摘 要
鋼筋彎曲機(jī)是建筑工業(yè)常用的工程機(jī)械之一,主要用于各種型號(hào)的鋼筋的彎曲,以用于工程在施工工地上。如何更有效提高機(jī)械生產(chǎn)效率,減少工人勞動(dòng)強(qiáng)度,提高鋼筋加工角度精度以及有更好的安全措施是鋼筋制作中被普遍關(guān)注的問(wèn)題。本文設(shè)計(jì)的GW40鋼筋彎曲機(jī)適用于建筑行業(yè)彎曲鋼筋之用。本機(jī)工作程序簡(jiǎn)單,彎曲形狀一致,調(diào)整簡(jiǎn)單,操作方便,性能穩(wěn)定.它能將Q23540圓鋼或8—36螺紋鋼筋彎曲成工程中所需的各種形狀。
本次設(shè)計(jì)先由兩種典型的傳動(dòng)方案入手,分別對(duì)其傳動(dòng)精度和傳動(dòng)效率進(jìn)行分析,從而選擇傳動(dòng)方案。然后簡(jiǎn)單說(shuō)明其主要的工作裝置的設(shè)計(jì)。通過(guò)對(duì)鋼筋彎曲所需扭矩的計(jì)算選擇電動(dòng)機(jī),再初步確定其傳動(dòng)裝置的運(yùn)動(dòng)和動(dòng)力參數(shù)。最后分別對(duì)V帶、圓柱齒輪、蝸輪蝸桿、軸等進(jìn)行相關(guān)的設(shè)計(jì)和計(jì)算。
通過(guò)此次對(duì)鋼筋彎曲機(jī)的結(jié)構(gòu)設(shè)計(jì)與運(yùn)動(dòng)分析,使我的理論和實(shí)際聯(lián)系的更加緊密,豐富了實(shí)踐經(jīng)驗(yàn),從中發(fā)現(xiàn)并彌補(bǔ)了好多自身不足之處,獲益匪淺。

Steel bending machine is commonly used in the construction industry,one of construction machinery,mainly for various types of bending steel bars for construction site.How to more effectively improve mechanical production efficiency more effectively, reduce labor intensity, improve the processing precision Angle steel and have a better security is a universal concern in che progress of steel making.The designed GW40 reinforced bending machineIn this pape is applicable to bend steel in the construction industry.Working procedure of the machine is simple, curved shape of the same ajustment is simple, easy to operate, stable performance.It will round or Q23540 thread 8-32 bending steel into works of various of forms required for.
In this design firstly the two typical transmission scheme of its transmission precision and respectively on transmission efficiency is analyzed, and choose transmission scheme. And then that the simple the main job of the design of the device. Through the calculation of bending torque required reinforced the choice of motor, and preliminary determine its transmission device sports and dynamic parameters. Finally, the V belt, cylindrical gears, worm and shafts of related is designed and calculated.
Through the reinforced bending machine to the structural design and movement analysis, It makes my theory and actual connection more closely, richs my practical experience, findsand makes up a lot of my own shortcomings, benefit.
Keyword: Steel bending machine;Bending moment;Spindle torque.
