摘 要
通過拉絲模拋光機的傳動機構圖，在消化、吸收、引進國外先進技術的基礎上,創(chuàng)新設計機械式拉絲模拋光機。本設計以機械結(jié)構設計為基礎完成了控制拋光絲往復移動的系統(tǒng)設計和夾緊拉絲模的夾緊裝置設計，帶傳動裝置具體參數(shù)和尺寸的設計以及關鍵零部件及總裝圖的三維造型。在拋光機系統(tǒng)設計中，主要完成了滑動導軌和曲柄滑塊機構的詳細連接設計，以及零件連接的結(jié)構設計和電機選擇。該拋光機的特點在于用曲柄滑塊機構來控制拋光絲的往復運動，通過拋光絲的往復運動和夾具的旋轉(zhuǎn)運動形成的復合運動來實現(xiàn)對拉絲模內(nèi)孔的研磨拋光。
關鍵詞：拉絲模拋光機；導軌；夾緊裝置；帶傳動
Abstract
On the basis of advanced foreign technology and the abroad picture materials of drawing die, the drawing die polishing machine has been designed creatively.Basing on the mechanical structural design, the creative design finished the design of hydraulic system which is used to control the reciprocating movement of polishing wire as well as the clamping device which is used to clamp polishing wire. And the specific parameters ,dimensions of belt driver transmission device, key components and the three-dimensional modeling have also been designed here. In the design of control system, I have mainly finished the four important designs which are hydraulic cylinders, fuel tanks, the structure of pumping systems’ connection parts and the choosing of coupling. The characteristics of this polishing machine is that it uses the double-piston hydraulic cylinders to control the reciprocating movement, then realizes the lapping and polishing on the hole in drawing die with the compound motion which is formed by the drawing wire’s reciprocating movement and the fixture’s rotary motion
Key Words: Drawing Die polishing machine; hydraulic transmission;clamping device ; belt transmission.
