Fig 2 Horizontal profile of a typical roll forming machine. Two pressure rollers supported on the automatic alignment of the spherical roller bearings, the bearings installed in the rack. The drive gear through the safety coupling with gear reducer input shaft. By the gear reducer motor speed is reduced to the speed of the pressure roller. Gear accelerator, the synchronization of the two helical gear and output shaft. Pressure roller and connected to double output shaft gear reducer with a the Jaw gear couplings. The pressure roller surface (Figure 3 can not see) the feeding system is installed. Did not indicate there to the main gear lubrication system device, the sliding section of bracket on the gearbox, coupling, and the pressure roller with hydraulic pressure from the device. 1. Safe coupling Molding machine work, material (adding) do not avoid zone ， A small iron and hard thing into the roller gear area and prevent roller the rotation of the wheels. In this case, in order to ensure that the molding machine the roller security work, the activities of the component must have a certain distance .The concessions from the translation of the function, and in serious cases can overload, united the open transmission shaft can take off. So the coupling design should have comfortable should this concession and safety protection function. This design USES the double friction roller type safe coupling, it with roller friction clutch and function, namely, use rolling the son chain, meet the molding machine activities on roller bearing a component big will move a type concession request; Use of friction transmission, setting overload protection. This safe coupling also has easy installation, adjustment and convenient maintenance, reliable working, long service life, not affected by environmental factors influence characteristics. 2. Pressure roller The most important part of the roll forming machine is the pressure roller itself. The different designs are possible. First of all, the pressure roller has Caine work the surface of solid forgings made. The hard surface allows suitable to choose a variety of surface structures for the production of high strength of the cake. Another way, the pressure roller of the roller core may be replaced. In this way, the roll itself is easy to be water cooled. The work surface of the roll ring is usually processed into a shallow ball and socket. The latest design of the molding machine used in this way. Conduction to the pressure roller temperature must be down to ensure that the bearings at low temperatures the surface of the roller ring must be cooled, usually due to higher feed temperature, in order to avoid the occurrence in the material surface melt. Fig 3 Profile of a typical roll forming machine The hard pressure roller advantage is that it can replace the simple machine parts. When the severe wear of the pressure roller surface, within the scope of the regulations in the outer diameter surface of the re-to welding . This will enable the device is always to maintain efficient operation. Of course, the use of pre-processed components can ensure that the people expected to pass the hot and would not make the pressure roller overheating. The inner surface of the heat of the cooling system sleeve (Figure 4) will be more economic use, and require the use of cleaner cooling water. In order to avoid improper handling of water in contact with the roller core corrosion, pressure roller and a cooling device cooling water system closure is appropriate. Most of the equipment used can shake a shallow rectangular metal box, with high and uniform density and strength in order to facilitate the discharge of air and ensure that the material bread. Advantages the figure, equipment selection of gear coupling is easy to disengage. Shown on the left, the upper pressure roller centerline is half of the coupling has been moved to the left, the pressure roller is easily torn off and the scene (to see cutaway view of stent). Fig 4 Briquetting machine with thermal sleeve and the cooling system pressure roller profile 3. Bearings (pressure roller support device) In modern large-scale briquetting machine, the pressure roller in the efficient and small size, self-calibrated spherical roller bearings. In this way, free to adjust especially in the wide pressure roller, pressure roller with removable feeding uneven and to the material thickness (how much). To ensure that the briquetting machine work more safely, it is crucial to the correct selection of the appropriate bearing. The most important considerations include the design of bearings and seals, cooling and lubrication. Bearing comprising a bearing force and distribution must be optimal. This requires a precise calculation. Come like Koppern latest briquetting machine, the actual deformation of the bearing is carried out detailed calculations using finite element method. The purpose of these calculations is consistent with the deformation of the bearing sleeve and the theoretical distribution of bearing loads (Figure 5). Fig 5 Self-calibration of spherical roller bearing load distribution map If necessary, cooling systems will ensure that the bearings at low temperatures, and can improve lubrication grease at low temperatures but also to ensure that the bearings in the bearing kit has a good sealing performance. High load, low speed bearing using a special grease, it has about as high as 10-3/m2 viscosity, and the addition of certain additives. 4. Feeding system Top of the feeding system in the bracket is facing the pressure briquetting machine roll gap. Feed fine and of or require large production, and some other special reason, a simple gravity feed chute may not be adopted in these cases, the screw feeder is a must. The diameter of the pitch characteristics of the screw feeder is in the center of the pitch and the edge of the feeding is not the same and the pitch of different geometric dimensions and the size of the roll gap area is restricted. To make the pressure roller machine uniform feed distribution along the roll width, using a multi-screw feeder. For example, a production capacity of 80 100t / h briquetting machine, single roller width is between 1000 1200mm, this requires the installation of multi-screw feeder. Spiral into a certain angle installed on both sides of the feeding center, under the action of gravity, the material into the feeder, conveying spiral pitch down, forcing the material directly into the pressure nip between the roll (Figure 6) Fig 6 Spiral to the schematic of the feeder In particular, fine-grained material in the compaction process, the materials in the air discharge plays an important role for the efficient work of the briquetting machine, for example, in the briquetting of the potassium salt, the density of the bulk material is about as 1g/cm3material the density of the cake is about 2 g/cm3, if the output of 100t / h, then approximately 50m3 / h air is discharged, so a lot of air through the pores of the bulk compound excreted. As the bulk compound pores become smaller with the compaction process, therefore, a tablet of this material will become more difficult. Pressure roll roll band to band compacted into blocks, because the material tightly fill the pressure roller, moving down the material in the air must be going against the logistics up the overflow, if not the quiver of the machine will result in the loss of machinery and equipment. Therefore, the design must implement (1) allow air discharged from the lower part of the feeder between the roll surface: (2) to ensure that the gap on both sides and the pressure roller shoulder angle (Figure 7). Fig 7 The escape of air in the briquetting machine Studies have shown that if roller width 600mm, over 500 air only from both sides of the overflow, this roller width limit always depends on the particle size distribution of bulk materials or the permeability of the bulk material. With the roll width increases, the air may be forced to clip roll band to bands material can not escape, resulting in a further increase in the briquetting machine load. To avoid this problem, briquetting machine of 1000 a total width of 1200mm, the total working width will be divided into two 500 a 600mm two parts, each part of the set up two spiral. In order to allow the air to overflow, all spiral is the same (see Figure 4), in order to meet the requirements of various feed speed and equipment production capacity, the speed of the screw must be adjusted separately. 5. Pressure stent Pressure stent in the design of briquetting machine, you must make it able to withstand the pressure of the high-pressure roller coming and supporting feeding system, usually with double stent. The so-called standard stents require easy maintenance, for example, due to wear or maintenance must be the pressure roller is removed. Not only that, like knock Koppern company and the development of a hinge bracket (Figure 8), this bracket is easy to remove or replace pressure roller. Bracket connected to the bottom of the vertical part of the horizontal portion of the above, the vertical bracket can be hinged at the down, remove part of the pressure roller attachment and floating roller side of the hydraulic tank, and disconnect the gear couplings grease piping, after connection of the cooling water system, the pressure roller can be pulled out to an easy overhead crane to lift. If using a standard bracket, replacement of a pressure roller of the fee may a week, while the articulated bracket may only need two classes can be. In order to make maintenance work more convenient, the design of a pressure roller to remove the device and a lifting bar, both connected with the pressure roller bearing box. Fig 8 Schematic of the articulated bracket 6. Drive gear The pressure roller drive gear of the machine by two large gear couplings, including synchronized helical gears, gear reducer, and a secure coupling between the people axis in the motor and gearbox input. Typically, the safety coupling is an automatic reset of the institutions, it can drive torque range of 1.7 to 1.9 times usual hours of work adjustment. Reduction gear consists of two parts : Reducers and synchronous torque distribution gear, under normal circumstances, the safety factor of the reducer for synchronous torque distribution gear safety factor of 2. The large gear reducer is equipped with oil cooling and filtering devices to ensure that the equipment of continuous operation. The most important is the connection of the synchronization gears and gear couplings guarantee provided to the uniform linear velocity of the pressure roller. Equipment in order to obtain higher yields only in the case of no shear stress. 7. Lubricating A continuous lubrication system provides continuous to the main gear and a sliding surface of the floating roller, reliable special grease. To ensure effective work, the lubrication system is monitored. Large machines tend to always have the automatic lubrication of the gear coupling system, it will give the device long-term continuous operation without having to stop for lubrication maintenance. 8.Hydraulic put pressure on the system The hydraulic put pressure on the system used to provide to the hydraulic tank pressure to change the pressure on roller closer to the compaction of materials and fixed roller. To meet special needs, the level and size of the pressure can be adjusted freely. Pressure gradient with the change of the pitch increased, the pressure gradient can be adjusted in a wide range by changing the sub-nitrogen in the hydraulic accumulator pressure. Also used as safety devices in the hydraulic system when the material is pressure pressure roller gap. An electric control system to monitor its function. 9 Frame In order to improve the speed of the old machine overloaded, and rigid he shortage problem, this design USES the from both left, up, right, with four The frame of a frame structure, each end frame with pin shaft link between, Make the convenient in assembling and disassembling, make simple, and the bearing can frame .Force is powerful, meet the large to roller machine work requirements. 黃河科技學(xué)院畢業(yè)設(shè)計(jì)（論文）開題報(bào)告表 課題名稱 360型對輥式壓塊機(jī)設(shè)計(jì) 課題來源 教師擬訂 課題類型 AX 指導(dǎo)教師 康紅偉 學(xué)生姓名 張國輝 專 業(yè)

360型對輥式壓塊機(jī)設(shè)計(jì)文獻(xiàn)綜述 在現(xiàn)代工業(yè)中，造粒，即用細(xì)粉狀分散的物料，通過加壓成型團(tuán)礦方法，轉(zhuǎn)化為顆粒狀產(chǎn)品，為此，要使用對輥式成型機(jī)。工藝技術(shù)條件的改進(jìn)，設(shè)備尺寸的增大，導(dǎo)致對輥成型機(jī)不斷進(jìn)步，當(dāng)然其目的是為了是每條線的生產(chǎn)能力更大。對輥成型機(jī)可以用于成型、壓塊和顆粒的高壓破碎，這種設(shè)備的給料裝置以及壓輥的表面將根據(jù)使用要求來設(shè)計(jì)。壓球機(jī)主要用于壓制難以成型的粉狀物料，其特點(diǎn)是成型壓力大、主機(jī)轉(zhuǎn)數(shù)可調(diào)、配有螺旋送料裝置。 　　主要用于：煤粉成型；干粉成型；脫硫石膏成型；焦粉成型；鐵屑及各種金屬礦粉成型等。壓球機(jī)技術(shù)先進(jìn)，質(zhì)量可靠，一機(jī)多用，壓力強(qiáng)大，適合大、中、小型企業(yè)建立具有一定生產(chǎn)規(guī)模的生產(chǎn)線。適用于工業(yè)造氣、鍋爐型、冷壓型焦點(diǎn)、點(diǎn)火型煤、民用型煤、民用冶金、耐材、醫(yī)藥等材料的各種成型。強(qiáng)力壓球機(jī)經(jīng)多年工業(yè)使用及改進(jìn)，與其它同類產(chǎn)品相比較，強(qiáng)力壓球機(jī)具有成球率高、消耗功率小，結(jié)構(gòu)緊湊便于檢修調(diào)試等明顯優(yōu)點(diǎn)。 壓球機(jī)構(gòu)造組成 　　壓球機(jī)結(jié)構(gòu)由三部分組成：給料部分；傳動(dòng)部分；成型部分。 　　1、給料部分，主要是實(shí)現(xiàn)定量給料來保證物料均勻進(jìn)入對輥間。螺旋送料裝置由電磁調(diào)速電機(jī)驅(qū)動(dòng)，經(jīng)皮帶輪、蝸桿減速器轉(zhuǎn)動(dòng)，將被 壓物料強(qiáng)制壓入主進(jìn)料口。由于電磁調(diào)速電機(jī)恒矩特性，當(dāng)螺旋送料機(jī)的壓料量與主機(jī)所需物料量相等時(shí)，可以保持恒定的供料壓力使球團(tuán)質(zhì)量穩(wěn)定。如供料量過大，則送料裝置的電過載;供料量過小則不成球。因此熟練的操作技是保證壓球正常工作的重要條件。 　　2、傳動(dòng)部分，主傳動(dòng)系統(tǒng)為：電動(dòng)機(jī)--三角形帶---減速機(jī)---開式齒輪---軋輥。主機(jī)由電磁調(diào)速電機(jī)提供動(dòng)力，經(jīng)皮帶輪、圓柱齒輪減速機(jī)，通過棒銷聯(lián)軸器傳至主動(dòng)軸。主動(dòng)軸與被動(dòng)軸通過開式齒輪保證同步運(yùn)行。被動(dòng)軸承座后邊裝有液壓裝置。液壓保護(hù)裝置是由液壓泵將高壓油打入液壓缸，使活塞產(chǎn)生軸向位移?；钊麠U的前接頭頂在軸承座上以滿足生產(chǎn)壓力要求。 　　3、成型部分，主要指主機(jī)部分，核心部分是軋輥。當(dāng)兩壓輥之間進(jìn)料過多或進(jìn)入金屬塊時(shí)，液壓缸活 塞桿受壓過載，液壓泵會(huì)停機(jī)、蓄能器對壓力變化起緩沖作用、溢流閥開啟回油、活塞桿移位使壓輥間縫隙加大從而使硬物通過壓輥，系統(tǒng)壓恢復(fù)正常，可以保護(hù)壓輥不損壞。華威機(jī)械制造根據(jù)壓球密度的要求調(diào)整壓力，生產(chǎn)機(jī)動(dòng)靈活。 功能用途 壓球機(jī)可用來壓制煤粉、鐵粉、焦煤、鋁粉、鐵屑、氧化鐵皮、碳粉、炭粉、礦渣、石膏、尾礦、污泥、高嶺土、活性炭、焦末等各種粉末、粉料、廢料、廢渣，廣泛應(yīng)用于耐材、電廠、冶金、化工、能源、運(yùn)輸、供暖等行業(yè)，經(jīng)壓球機(jī)制作成型后的物料，節(jié)能環(huán)保，便于運(yùn)輸，提高了對廢料的利用率，具有良好的經(jīng)濟(jì)效益和社會(huì)效益。 結(jié)構(gòu)原理 　　主電機(jī)：經(jīng)V形帶，傳至減速器：減速器通過聯(lián)軸器，傳至主動(dòng)軸再由一對開式齒輪，保證兩輥軸同步 ??（等速相反）其中被動(dòng)輥由液壓油缸的活塞頂?。ê銐菏降挠尚辫F頂住），由液壓回路及液壓控制閥和蓄能器保證系統(tǒng)壓力，物料由貯料倉經(jīng)定量設(shè)備均勻地進(jìn)入成型機(jī)料斗，通過料斗上的調(diào)節(jié)閘板調(diào)節(jié)，使物料均勻的進(jìn)入對輥中間，等速反向運(yùn)轉(zhuǎn)的對輥進(jìn)行壓縮物料的單位成型壓力由小變大，在對輥中心線處成型壓力達(dá)到最大值，物料過該線后，成型壓力迅速變小使物料進(jìn)過脫球狀態(tài)，順利脫球。 工作原理：對輥式壓球機(jī)的主要部件是一對直徑相等，彼此留有一定間隙的對輥。兩對輥以相同的轉(zhuǎn)速做反方向旋轉(zhuǎn)。兩對輥表面上規(guī)則的排列許多形狀大小相同的球窩。兩對輥呈水平布置，粉粒狀物料從兩對輥上方連續(xù)、均勻的加入，主要靠小料倉內(nèi)的預(yù)壓螺旋進(jìn)行強(qiáng)制喂料進(jìn)入兩對輥之間。送入對輥前，物料作自由流動(dòng)，從對輥表面的某點(diǎn)起被對輥咬入。隨著對輥的旋轉(zhuǎn)，物料占有的空間逐漸減小，逐漸被壓縮，達(dá)到成型壓力最大值，隨后則壓力逐漸減小。所壓的型球因彈性恢復(fù)而產(chǎn)生尺寸增大，球與球窩壁的粘和受到破壞，加上其本身的重量而順利脫落。 壓球機(jī)等型煤設(shè)備技術(shù)發(fā)展的有以下四個(gè)重要問題： 1、解決廉價(jià)、來源廣、效果好的粘結(jié)劑 ??型煤是用一種或數(shù)種煤粉與一定比例的粘結(jié)劑或固硫劑在一定壓力下加工形成的，具有一定形狀和一定理化性能的煤炭產(chǎn)品。軟瀝青作為配型煤技術(shù)的基本粘結(jié)劑，具有價(jià)格高，在煉焦過程中50％轉(zhuǎn)為焦炭材料，故周轉(zhuǎn)損失多的缺點(diǎn)，且軟瀝青可廣泛用于生產(chǎn)瀝青焦或針狀焦，是一種貴重的瀝青資源。因此，尋找廉價(jià)、來源廣、效果好的粘結(jié)劑替代軟瀝青，是配型煤煉焦發(fā)展的一個(gè)關(guān)鍵。 2、煤料與粘結(jié)劑充分混捏 ??這是保證最有效地利用粘結(jié)劑和提高成型煤強(qiáng)度的重要環(huán)節(jié)，混捏機(jī)是實(shí)現(xiàn)充分混捏的關(guān)鍵設(shè)備。 3、操作可靠的壓球機(jī) ??一般均使用對輥式壓球機(jī)。這種成型機(jī)生產(chǎn)能力大，結(jié)構(gòu)緊湊，壓制的型球均勻，但受壓時(shí)間短，成型壓力為20～50mpa，這對有粘結(jié)劑的冷壓型煤是足夠的。為在較短受壓時(shí)間內(nèi)壓實(shí)煤料，設(shè)有均勻布料和給料調(diào)節(jié)裝置。為保證壓出完整的型球，兩個(gè)壓輥還應(yīng)設(shè)有相應(yīng)的軸向和徑向間隙的調(diào)節(jié)機(jī)構(gòu)。對輥壓球機(jī)的球碗形狀和光滑度是影響能否順利脫模的重要因素，一般采用厚度不大的枕型球碗。 4、型球的冷卻、輸送和防破碎 ??這是保證型球整球率的又一重要環(huán)節(jié)。由于成型球是在80～100mpa下進(jìn)行，此時(shí)粘結(jié)劑均布在煤粒表面上，但仍屬液膜狀，故型煤強(qiáng)度不大。采用帶空氣通風(fēng)冷卻的網(wǎng)式運(yùn)輸機(jī)，可以在輸送型煤的同時(shí)，冷卻型煤提高強(qiáng)度，但要縮短運(yùn)輸距離，減少運(yùn)轉(zhuǎn)和進(jìn)倉時(shí)的落差，并采取相應(yīng)的防破碎裝置。也有的將型球卸至粉煤運(yùn)輸帶上，與粉煤一起運(yùn)轉(zhuǎn)，以減少撞擊，提高整球率。 壓球機(jī)分類： ?? ? 根據(jù)壓球機(jī)原理結(jié)構(gòu)形式可分為：兩輥壓球機(jī)，四輥壓球機(jī)。 ??????根據(jù)壓球機(jī)的壓力強(qiáng)度可分為：低壓壓球機(jī)，強(qiáng)力壓球機(jī)，高強(qiáng)壓球機(jī)。 ??????根據(jù)壓球機(jī)的用途可分為：礦粉壓球機(jī)，型煤壓球機(jī)，脫硫石膏壓球機(jī)，干粉壓球機(jī)等。 ??????根據(jù)加工物料常見名字：如鐵粉壓球機(jī)，錳粉壓球機(jī)，高嶺土壓球機(jī)等等?。?型煤壓球機(jī)核心設(shè)備“減速機(jī)”的選型設(shè)計(jì) ? 合理選型的重要性 ?????? ? 減速機(jī)的選型與型煤選型、型煤設(shè)計(jì)、型煤壓球機(jī)選型一樣重要，選好了，設(shè)備功效可淋漓盡致的發(fā)揮，選不好，則無法順利投產(chǎn)。減速機(jī)是型煤壓球機(jī)的核心設(shè)備，好的型煤壓球機(jī)，必有一個(gè)安全、穩(wěn)定、耐久度減少機(jī)與其相配套，那么，如何正確認(rèn)知、選購型煤壓球機(jī)減速機(jī)呢？減速機(jī)是型煤壓球機(jī)的好搭檔，其選型設(shè)計(jì)不可小視。減速機(jī)設(shè)計(jì)是按照壓球機(jī)的要求設(shè)計(jì)的，其型號與壓球機(jī)型號也恰恰相對。鄭州威力特先帶您了解一下減少機(jī)的相關(guān)知識(shí)，以便您更好的了解其功能及重要性。 減速機(jī)基本知識(shí) 減速機(jī)定義：減速機(jī)又稱為增速器、減速器，減速器是指原動(dòng)機(jī)與工作機(jī)之間獨(dú)立封閉式傳動(dòng)裝置， 用來降低轉(zhuǎn)速并相應(yīng)地增大轉(zhuǎn)矩。 在 某些場合，也有用作增速的裝置，并稱為增速器。 減速機(jī)構(gòu)造：型煤壓球機(jī)配套裝置減速機(jī)內(nèi)部構(gòu)造比較簡單，主要由傳動(dòng)零件、 軸、軸承、箱體及其附件所組成，其基本結(jié)構(gòu)有三大部分：1）齒輪、軸及軸承組合；2）箱 體；3）減速器附件。 如何正確選擇減速機(jī)？ 選擇型煤壓球機(jī)減速機(jī)，需要根據(jù)選擇的機(jī)型號、負(fù)載轉(zhuǎn)距、傳動(dòng)比、輸出轉(zhuǎn)速確定所需的電機(jī)規(guī)格等來選配。 1、盡量選用接近理想減速比： 減速比=輸入轉(zhuǎn)速/輸出轉(zhuǎn)速； 2、扭矩計(jì)算：對減速機(jī)的壽命而言，扭矩計(jì)算非常重要，并且要注意加速度的最大 轉(zhuǎn)矩值(TP)，是否超過減速機(jī)之最大負(fù)載扭力； ?3、減速機(jī)的適用性很高，工作系數(shù)都能維持在 1.2 以上，但在選用上也可以根據(jù)自己的 需要來決定； 4、輸入軸徑不能大于提供的最大使用軸徑； 5、根據(jù)選擇的機(jī)型號、負(fù)載轉(zhuǎn)距、傳動(dòng)比、輸出轉(zhuǎn)速確定所需的電機(jī)規(guī)格；這些選型知識(shí)比較深，如果您不太了解到話，可留言咨詢，鄭州威力特將在最短時(shí)間內(nèi)給您恢復(fù)，為您解決難題。 小結(jié) 不同型號的型煤壓球機(jī)，對應(yīng)著不同的減速機(jī)。減速機(jī)的選型包括原始條件、選擇類型、確定規(guī)格等步驟。 相比之下，類型選擇比較 簡單，而準(zhǔn)確提供減速器的工況條件，掌握減速器的設(shè)計(jì)、制造和使用特點(diǎn)是減速器正確合 理選擇規(guī)格的關(guān)鍵。規(guī)格選擇要滿足強(qiáng)度、熱平衡、軸伸部位承受徑向載荷等條件。 參考文獻(xiàn)： 1. 徐灝.機(jī)械設(shè)計(jì)手冊（第四冊）.北京：機(jī)械工業(yè)出版社，1991 2. 王華坤，范元?jiǎng)?機(jī)械設(shè)計(jì)基礎(chǔ)（Ⅱ）.北京：兵器工業(yè)出版社，2001.6 3.
