本文簡(jiǎn)要分析了鋼筋調(diào)直切斷機(jī)、彎曲機(jī)、套絲機(jī)的工作原理及其的應(yīng)用。 鋼筋作為混凝土的骨架構(gòu)成鋼筋混凝土，成為建筑結(jié)構(gòu)中使用面大、量大的主材。在澆注混凝土前，鋼筋必須制成一定規(guī)格和形式的骨架納入模板中。制作鋼筋骨架，需要對(duì)鋼筋進(jìn)行強(qiáng)化、拉伸、調(diào)直、切斷、彎曲、連接等加工，最后才能捆扎成形。由于鋼筋用量極大，加工操作難以完成，需要采用各種專用機(jī)械進(jìn)行加工，這類機(jī)械稱為鋼筋加工機(jī)械，簡(jiǎn)稱鋼筋機(jī)械。 為了增加鋼筋混凝土粱、屋架等主要結(jié)構(gòu)的強(qiáng)度．常采用預(yù)應(yīng)力鋼筋混凝土，即預(yù)先將鋼筋(鋼絲束或鋼鉸線)拉伸到設(shè)計(jì)應(yīng)力，并錨固于結(jié)構(gòu)受拉區(qū)內(nèi)，使其產(chǎn)生有利的壓應(yīng)力利應(yīng)變，用以抵消荷載時(shí)產(chǎn)生的拉應(yīng)力，從而增加其荷載能力。張拉鋼筋產(chǎn)生預(yù)應(yīng)力的專用設(shè)備，稱為鋼筋預(yù)應(yīng)力機(jī)械。 現(xiàn)代建筑施工中，由于鋼筋混凝土用量日益增大，鋼筋加工量相應(yīng)增加，促使鋼筋機(jī)械不斷發(fā)展。一般施工現(xiàn)場(chǎng)和預(yù)制混凝土構(gòu)件廠都有一定規(guī)模的鋼筋加工車間，為實(shí)現(xiàn)鋼筋加工機(jī)械化提供有利條件。 隨著社會(huì)經(jīng)濟(jì)的發(fā)展,產(chǎn)品的多樣化及對(duì)市場(chǎng)的快速反應(yīng)成為企業(yè)能否在激烈的市場(chǎng)競(jìng)爭(zhēng)中處于有利位置的必備能力，這就對(duì)企業(yè)的生產(chǎn)設(shè)備提出了更高地要求如何提高生產(chǎn)設(shè)備的柔性和效率,滿足產(chǎn)品的多樣化的需要,是每個(gè)企業(yè)都面臨著的一個(gè)重要問題，尤其是近些年來住宅產(chǎn)業(yè)、能源交通等基礎(chǔ)設(shè)施建設(shè)不斷發(fā)展，鋼筋砼結(jié)構(gòu)的跨度和規(guī)模不斷擴(kuò)大，對(duì)建筑物、構(gòu)筑物使用年限的提高，對(duì)抗震、節(jié)能、節(jié)材要求的提高，施工難度不斷增加，傳統(tǒng)施工方法及現(xiàn)場(chǎng)手工操作已不適應(yīng)工程的要求，只有發(fā)展鋼筋加工商品化才能滿足建筑結(jié)構(gòu)和工程新技術(shù)發(fā)展的需要，就是在這樣的背景下,我們即將設(shè)計(jì)一種適用于鋼筋鋼管多種加工的產(chǎn)品。 在當(dāng)今的建筑施工現(xiàn)場(chǎng)，工人一般使用的是機(jī)械式的鋼筋加工設(shè)備，這樣的設(shè)備不但占用的場(chǎng)地大，而且費(fèi)力費(fèi)時(shí)，同時(shí)沒有安全保護(hù)措施，極易造成工人的受傷；有些雖然占地少，但是工序繁雜，不能同時(shí)加工出所須的鋼筋用件，并且噪聲大，不宜控制，鑒于以上的情況，有必要設(shè)計(jì)一種有液壓系統(tǒng)統(tǒng)一提供動(dòng)力的多功能鋼筋鋼管加工機(jī)械，可以適用于中小型建筑隊(duì)，該加工機(jī)動(dòng)作方便靈活，便于掌握，移動(dòng)，安裝簡(jiǎn)便可靠。 鋼筋切斷機(jī)是把鋼筋原材或已校直的鋼筋按配料計(jì)算的長(zhǎng)度要求進(jìn)行切斷的專用設(shè)備。廣泛應(yīng)用于施上現(xiàn)場(chǎng)和構(gòu)件預(yù)制廠剪切6—40mm的鋼筋。更換相應(yīng)刀片，還可作為各種型鋼的下料機(jī). 切斷機(jī)的使用 1．使用前的準(zhǔn)備工作 1.1鋼筋切斷機(jī)應(yīng)選擇堅(jiān)實(shí)的地固安置平穩(wěn)，機(jī)身鐵輪用三角木楔好，接送料工作臺(tái)面府和切刀的刀刃下部保持水平，工作臺(tái)的長(zhǎng)度可根據(jù)加工材料的長(zhǎng)度決定，四周應(yīng)有足夠搬運(yùn)鋼筋的場(chǎng)地。 1.2使用前必須清除刀口處的鐵銹及雜物．檢查刀片應(yīng)無裂紋，刀架螺栓應(yīng)緊固防護(hù)罩應(yīng)完好，接地要牢固，然后用于扳動(dòng)帶輪，檢查齒輪嚙合間隙，調(diào)整好刀刃間隙、定刀片和動(dòng)刀片的水平間隙以0.5—1mm為宜。間隙的調(diào)整，通過增減固定刀片后面的墊塊來實(shí)現(xiàn)。 1.3按規(guī)定向各潤(rùn)滑點(diǎn)及齒輪面加注和涂抹潤(rùn)滑油，液壓式的還要補(bǔ)充液壓油： 1.4起動(dòng)后先空載試運(yùn)轉(zhuǎn)．整機(jī)運(yùn)行應(yīng)無卡滯和異常聲響，離合器應(yīng)接觸平穩(wěn)，分離徹底。若是液壓式的，還應(yīng)先排除油缸內(nèi)空氣，待各部確認(rèn)正常后，方可作業(yè)。 2．操作要點(diǎn) 2.1新投入使用的切斷機(jī)，應(yīng)先切直徑較細(xì)的鋼筋，以利于設(shè)備磨合。 2.2被切鋼筋應(yīng)先調(diào)直，切料時(shí)必須使用刀刃的中下部位、并應(yīng)在動(dòng)刀片后退時(shí)，緊握鋼筋對(duì)準(zhǔn)刀口迅速送人，以防鋼筋末端擺動(dòng)或蹦出傷人。嚴(yán)禁在動(dòng)刀片已開始向前推進(jìn)時(shí)向刀門送料，否則易發(fā)生事故。 2.3嚴(yán)禁切斷超出切斷機(jī)規(guī)定范圍的鋼筋和材料。一次切斷多根鋼筋時(shí)，其總截面積應(yīng)在規(guī)定范圍以內(nèi)。禁止切斷中碳鋼鋼筋和燒紅的鋼筋。切斷低合金鋼等特種鋼筋時(shí)，應(yīng)更換相應(yīng)的高硬度刀片。 2.4斷料時(shí)，必須將被切鋼筋握緊，以防鋼筋末端擺動(dòng)或彈出傷人。在切短料時(shí)，靠近刀片的手和定刀片之間的距離應(yīng)保持150mm以上，如手握一端的長(zhǎng)度小于400mm時(shí)，用套管或夾具將鋼筋短頭壓住或夾緊，以防彈出傷人。 2.5在機(jī)械運(yùn)轉(zhuǎn)時(shí)，嚴(yán)禁用手去摸刀片或用于直接去清理刀片上的鐵屑，也不可用嘴吹。鋼筋擺動(dòng)周圍和刀片附近，非操作人員不可停留。切斷長(zhǎng)料時(shí)，也要注意鋼筋擺動(dòng)方向，防止傷人。 2.6運(yùn)轉(zhuǎn)中如發(fā)現(xiàn)機(jī)械不正?；蛴挟愴懀约俺霈F(xiàn)刀片歪斜、間隙不合等現(xiàn)象時(shí)，應(yīng)立即停機(jī)檢修或調(diào)整。 2.7工作中操作者不可擅自離開崗位，取放鋼筋時(shí)既要注意自己，又要注意周圍的人。已切斷的鋼筋要堆放整齊，防止個(gè)別切口突出，誤踢割傷。作業(yè)后用鋼刷清除刀口處的雜物，并進(jìn)行整機(jī)擦拭清潔。 2.8液壓式切斷機(jī)每切斷一次，必須用手扳動(dòng)鋼筋，給動(dòng)刀片以回程壓力，才能繼續(xù)工作。 為了保證鋼筋在混凝土結(jié)構(gòu)中的相互連接，提高預(yù)制構(gòu)件的強(qiáng)度。必須對(duì)鋼筋進(jìn)行配胃，彎曲成設(shè)汁圖紙所要求的尺寸和形狀．這是鋼筋加工中一道重要的加工工序。因此．在鋼筋加工機(jī)械中，鋼筋彎曲機(jī)械同樣是重要的鋼筋加工設(shè)備之一. 目前，為了更適應(yīng)于建筑行業(yè)的發(fā)展方向，成功設(shè)計(jì)了一種液壓鋼筋彎曲切斷機(jī)，它是由液壓傳動(dòng)和操縱的兩用機(jī)床，適用于加工直徑為6—32mm的鋼筋。這種彎曲機(jī)還可以進(jìn)行切斷工作，是一種兩用機(jī)械，自動(dòng)化程度高，操作方便，但不能同時(shí)進(jìn)行切斷和彎曲兩項(xiàng)工作。該機(jī)械有一臺(tái)電動(dòng)機(jī)帶動(dòng)兩組柱塞式液壓泵，一組推動(dòng)切斷用活塞；另一組驅(qū)動(dòng)回轉(zhuǎn)液壓缸，帶動(dòng)工作盤旋轉(zhuǎn)。同時(shí)，為了移動(dòng)方便，機(jī)械底盤上裝有行走輪。但是這樣的兩用機(jī)械有一個(gè)缺點(diǎn)就是不能同時(shí)進(jìn)行加工。 鋼筋彎曲機(jī)的使用 1為適應(yīng)鋼筋和中心軸直徑的變化，應(yīng)在成形軸上加——個(gè)偏心套，用以調(diào)節(jié)中心軸、鋼筋和成形軸三者之間的間隙. 2根據(jù)彎曲鋼筋的直徑更換配套齒輪，以調(diào)整工作盤(主軸)轉(zhuǎn)速。當(dāng)鋼筋直徑d＜18mm 時(shí)取高速；d＝18—32mm 時(shí)取中速；d＞32mm時(shí)取低速：一般工作盤常放在慢速上，以便彎曲在允許范圍內(nèi)所有直徑的鋼筋。 3當(dāng)彎曲鋼筋直徑在20mm以下時(shí)，應(yīng)在插入座上放置擋料架，并有軸套，以使被彎鋼筋能正確成形。擋板要貼緊鋼筋，以保證彎曲質(zhì)量。 4業(yè)前先進(jìn)行空載試運(yùn)轉(zhuǎn)，應(yīng)無卡滯、異響，各操縱按鈕靈活可靠；再進(jìn)行負(fù)載試驗(yàn)，先彎小直徑鋼筋，再彎大直徑鋼筋，確認(rèn)正常后、方可投入使用。 鋼筋套絲機(jī) 即鋼筋螺紋連接設(shè)備的一種， 鋼筋螺紋連接設(shè)備和工具主要有鋼筋套絲機(jī)、量規(guī)、力矩扳手和砂輪鋸等。 傳統(tǒng)的加上方法是手工在車床上扳牙，而手工扳牙最大的困難是定心難，對(duì)于大批量生產(chǎn)時(shí)，手工扳牙存在著勞動(dòng)強(qiáng)度大、生產(chǎn)效率低、不安全等問題。為此，我們?cè)O(shè)計(jì)了一種扳牙自動(dòng)定心套絲裝置。 工作原理:將所用標(biāo)準(zhǔn)的扳牙放于調(diào)緊圈內(nèi)(調(diào)緊圈的大小根據(jù)扳牙的大小由調(diào)節(jié)栓 )，用定位栓將扳牙鎖緊在調(diào)緊圈內(nèi)。將套8的錐柄桿套于車床尾座內(nèi)，固定尾座，車床正轉(zhuǎn)運(yùn)廳了，搖動(dòng)尾座手輪，扳牙白動(dòng)定心，隨著工件轉(zhuǎn)動(dòng)，殼體在套體內(nèi)向左滑動(dòng)，同時(shí)扭縮彈簧(彈簧由限位塊限位)進(jìn)行扳牙。扳牙完成后，將車床反轉(zhuǎn)運(yùn)行，在彈簧的反彈力作用下，殼體自動(dòng)退出，完成扳牙。鐵屑從殼體上銑的一個(gè)落屑槽中落下。 由于調(diào)緊圈上銑有缺口，可以通過調(diào)節(jié)栓來調(diào)節(jié)其大小，所以此裝置可以用于扳不同規(guī)格的螺紋。它既解決了手工扳牙定心難的問題，又減輕了勞動(dòng)強(qiáng)度，大大提高了生產(chǎn)效率。 展望前景，隨著建筑施工機(jī)械化程度的提高，液壓技術(shù)和電子技術(shù)在鋼筋機(jī)械中加快應(yīng)用，微機(jī)自動(dòng)控制技術(shù)的逐漸普及，將使鋼筋機(jī)械自動(dòng)化和半自動(dòng)化的新面貌早日實(shí)現(xiàn)。 設(shè)計(jì) 文獻(xiàn)翻譯 院（系）名稱 專業(yè)名稱 學(xué)生姓名

The Chinese-English summary 】 this text synopsis analyzes the reinforcing bar to adjust to keep the work principle of cut off the machine, the flection machine, a silk machine and it of application. Extend continuously along with the capital construction scale since the reform open. the dosage of the reinforced concrete hoick, urging the reinforcing bar machine in ushering in the foundation of[with] foreign technique or the kind machine. speed to develop a step.some techniques with new adoptions develop success with multi-function new model one after another, entering batch quantity production.Applied a liquid to press the technique,electronics technique,calculator control technique in the reinforcing bar take shape,weld and prepare should the dint machine particularly etc., make the dynasty of the reinforcing bar machine wear the half automation with full-automatic turn a development. The reinforcing bar is the framework of the concrete to constitute reinforced concrete, become construct to use noodles in the structure big,have great capacity of main material.Before sprinkling to note concrete, the reinforcing bar has to be made into the certain specification and the framework of the form to bring into template.Manufacture the reinforcing bar framework, need to carry on enhance,pull to stretch,adjust to keep,cut off,curve,link to the reinforcing bar etc. process, then can tie～up to tie to take shape finally.Because the reinforcing bar dosage processes to operate hard completion biggest, need to adopt various appropriation machine to carry on to process, this machine is called reinforcing bar to process a machine, the brief name reinforcing bar machine. For increasing reinforced concrete,the house the strength of the structure with main etc..often adopt to prepare should the dint reinforced concrete, pull reinforcing bar(the steel wire tie or the steel 鉸 line) to stretch a design dint in advance namely, and the anchor man is solid is pulled area in the structure inside, make it creation's pressing beneficially should the dint benefit meet an emergency, offsetting a lotus to carry in order to creation of pull should dint, increase its lotus to carry an ability thus.ZHANG LA's reinforcing bar creation's prepare should the appropriation equipments of the dint, be called reinforcing bar to prepare should dint machine. The modern construct under construction, because the reinforced concrete dosage enlarges increasingly, the reinforcing bar processes quantity to correspond increment, urging the reinforcing bar machine to develop continuously.General the construction the spot with prepare to make the concrete piece, the factories all have the reinforcing bar of the certain scale to process the car, for carry out reinforcing bar to process mechanization to provide a beneficial condition. Along with the development of the society economy, the diversification of the product and become to the fast reaction of the market business enterprise can in the vehemence of be placed in the essential ability of the beneficial position in the market competition, this put forward to the production equipments of the business enterprise higherly a request"how raise to produce an equipments of gentle with efficiency, satisfy a product of the demand of the diversification, is each business enterprises face of an important problem is the infrastructure constructions, such as particularly nearer in the last years residence industry and the energy transportation...etc. to develop continuously, the reinforcing bar structure of across the degree and scale to extend continuously, To the building,construct the exaltation of the thing usage time limit, resist an earthquake,economize on energy,the exaltation of the stanza material request, start construction the difficulty increase continuously, the tradition construction method and the spot handicraft operation are unwell already at the request of engineering, only developping reinforcing bar to process to commercialize then can satisfy building the structure and engineering the new technique development of demand be under this background, we will soon design a kind of be applicable to the reinforcing bar steel pipe various processed products. Construct a construction the spot nowadays, worker generally what to use is the reinforcing bar of the machine type to process an equipments, such equipments takes up not only of place big, and hard to tackle time-consuming, have no safety protection measure in the meantime, result in the worker get hurt easier Some although cover little, the work preface is complicated, can't process to use a piece the reinforcing bar of the beard in the meantime, and the voice is big, not proper control, owing to above circumstance, there is necessity to design a kind of have a liquid to press system to unify to provide dynamical multi-function reinforcing bar steel pipe to process a machine, can be applicable to a medium small scaled building brigade, should process mobile make convenience vivid, easy to control, move, install simple credibility. Reinforcing bar's cutting off machine is reinforcing bar original material or already the school keep of the reinforcing bar presses to go together with the appropriation equipments that length request of anticipate the calculation carries on cut off.Extensively applied in SHI SHANG3 the spot and the piece reinforcing bar that prepare to make factory to shear to slice a 6-40 mms.Replace to correspond razor blade, can also conduct and actions various steel descend to anticipate machine. Cut off the usage of the machine 1.usage ex- preparation work (1)Reinforcing bar's cutting off machine should choose a solid setting of solid ground steady, the fuselage of airplane iron round uses the wedge good, the knife blade lower part that connects to send to anticipate the work set noodles mansion and slices knife keeps level, the length of the work pedestal can according to process the length decision of the material, on all sides should have the place of the enough porterage reinforcing bar. (2)Before use have to clearance the rust and miscellaneous articles or objects of the edgy place.The check razor blade should have no crack, the knife stud bolt should the tightly solid protection cover should be intact, connecting ground to want firm, then used for pulling to move to take a round, check the wheel gear to match cleft, adjust good knife blade cleft and settle razor blade and fight with weapons the level cleft of the slice to take 0.5-1 mms as proper.The adjustment of the cleft, pass the mat piece of increase or decrease the behind of the fixed razor blade to carry out. (3)By rule order toward each lubrication and the wheel gear noodles add to note with the daubery lubricant, the liquid press type still needs to add a liquid to press oil: (4)Get empty first to carry to try an operation after start.the whole luck go and should have no card and excrescent voice to ring, the clutch deals with to touch steady, separate thoroughly.If the liquid press type of, should also expel the oil air inside the urn first, after needing each confirmation normally, square can homework. 2.the operation important point (1)The new devotion use of cut off machine, should slice thinner reinforcing bar of diameter first, for the convenience of whetting to match in the equipments. (2)Being slice reinforcing bar should adjust first to keep, have to use the medium lower part of the knife blade while slicing to anticipate and should grip reinforcing bar to aim at edge of knife to send a person quickly while fight with weapons a slice of countermarch also, in order to prevent the reinforcing bar bitter end swing or leap a wound person.Strictly forbid while fighting with weapons a slice to have already forwarded start push forward send to anticipate toward the knife door, otherwise take place trouble easily. (3)Strictly forbid to cut off to outrun the reinforcing bar and the material of cut off the machine provision scope.While cutting off several reinforcing bars once, its always cutting area should Be ruling scope in.Forbid to cut off the medium carbon steel reinforcing bar and burn red reinforcing bar.Cut off a low metal alloy steel etc. the special kind reinforcing bar, should replace to correspond of high degree of hardness razor blade. (4)Have to will be slice reinforcing bar to fist while breaking to anticipate, in order to prevent the reinforcing bar bitter end swing or flick harm a person open to.At slice short anticipate, close to the hand of the razor blade with settle an of razor blade of the distance should keep a 150 mms above, if hold a carry of use a set of tube or tongs when the length is small in the 400 mms reinforcing bar the short head suppress or clip tightly, in order to prevent flick wound open person. (5)At the machine revolve, strictly forbid to touch razor blade or used for by hand tidy up the iron scraps of the razor blade directly, can't blow with the mouth, either.The reinforcing bar swings the surroundings and razor blade a neighborhood, operating a personnel not can't stop over.Also want to notice the reinforcing bar swing direction while cutting off to grow to anticipate, prevent°from harming a person. For the sake of assurance reinforcing bar is in the concrete structure of link mutually, raise to prepare strength of make the piece.Have to carry on go together with to the reinforcing bar Stomach, the flection becomes to establish the size and shape that the juice diagram paper request. this BE, in the reinforcing bar that process to process a work preface together and importantly.Therefore.at The reinforcing bar processes a machine in, the reinforcing bar flection machine the similarly important reinforcing bar process one of the equipmentses; Currently, for being adapt in a development direction of construct the profession more, success design a kind of liquid press the reinforcing bar flection to cut off machine, it is press by the liquid to spread to move and manipulate of two use tool machine, be applicable to process the diameter as the reinforcing bar with 6-32 mms.This kind of bent machine can be also carry on cutting off a work, is a kind of two use a machine, automation the degree is high, operation convenience, but can't be in the meantime carry on cut off and curve two works.That machine has a the set electric motor to arouse two sets of pillar fill type liquids to press a pump, a set of push cuts off to use piston;Another a set of drive to turn round a liquid to press an urn, arouse a work to hover around to turn.In the meantime, for moving convenience, have to run about a round on the machine bedrock.But such of two have a weakness with the machine be can't be in the meantime carry on process. The usage of the reinforcing bar flection machine 1，In order to adapt the variety of the reinforcing bar and the central axis diameter, should add in taking shape stalk- the partiality set, regulate central axis,reinforcing bar and take shape stalk three clefts of in order to. 2，According to the diameter of the flection reinforcing bar replace the kit wheel gear to turn by adjusting the work dish(principal axis) soon.When the reinforcing bar diameter d<18 mms take high speed;D=18-32 mms take medium soon;D>32 mms take low speed:General work the dish often put on slowly and soon, in order to flection all diametral in allow the scope of reinforcing bar. 3，When curve the reinforcing bar diameter following in the 20 mm, should place to block to anticipate on inserting, also the stalk set with make curved reinforcing bar of quilt ability the exactitude take shape.Block the plank wants to stick tight reinforcing bar, curving quality by assurance. 4，Homework the ex- forerunner go to get empty to carry to try an operation, should have no card ,the difference ring, each manipulate to press button vivid credibility;Carry on again a load to experiment, bend small diameter reinforcing bar first, then bend big diameter reinforcing bar, confirm a normal empress,the square can throw in an usage. Set of steel wire The reinforcing bar set silk machine namely the reinforcing bar thread conjunction equipments of a kind of, the reinforcing bar thread conjunction equipments and tool mainly have the reinforcing bar set the silk machine,quantity the rules,the dint wrench and emery wheel saw etc.. Plusing a method traditionally is a handicraft to pull a tooth on the lather, but the handicraft pull a biggest difficulty of tooth is fix mind difficult, for When the large quantity produce, the handicraft pulls a tooth to exist a labor strength big,produce an efficiency a low and uneasy and identically equal problem.For this, we design a kind of pull a tooth to fix mind a set of silk to equip automatically. The work principle:pull the standard use the tooth put in adjust a tight inside of circle(adjust the size of the tight turn according to pull the size of the tooth from regulate to bolt), bolting with the fixed position will pull the tooth lock tightly Be adjusting a tight inside of circle.Set of the awl handle pole set in the lather tail inside, fix the tail, the lather was transport hall, waving the tail the hand round, pulling the tooth white to move to fix mind, turning to move along with the work piece, the hull body at set left glide with introverted body, twist the spring coil(spring coil from limit piece the limit) to carry on pulling a tooth in the meantime.Turn over lather after pulling the tooth completion movement, under the rebound dint function of the spring coil, the hull body withdraws automatically, completing to pull a tooth.The iron scraps falls the scraps slot to decline a bottom from an of the hull body top . In order to adjusting to fence in to there is indentation tightly, can pass to regulate to bolt to regulate its size, so this device can used for the thread that pulls different specification.It since resolved handicraft to pull a tooth to fix mind a difficult problem, and then eased the labor strength, raised to produce an efficiency consumedly. Prospect foreground, along with construct the exaltation of[with] the construction mechanization degree, the liquid presses the technique and the electronics technique to speed an application in the reinforcing bar machine, the tiny machine controls automatically technical gradual universality, will make the reinforcing bar machine automate to automate and half of the new feature carries out soon.
