摘要
针对内螺纹冷挤压成形加工工艺设计出一套低频振动加工装置。通过该装置对挤压丝锥施加低频振动,从而改善挤压区的恶劣环境,进而达到降低挤压温度、挤压扭矩、促进冷却润滑液进入挤压区和减少挤压丝锥折断的目的。首先,给出该装置的总体方案,并对其中的振动源选取和振动杆、振动板、固定板和底座的设计给予详细说明;其次,基于Adams对该装置进行动力学仿真,通过获得的振动板振动位移曲线和振动杆的角位移曲线,表明该装置可以对挤压丝锥施加振动,使其产生微小的圆周方向振动,进而达到内螺纹的振动冷挤压加工。
A set of low frequency vibration processing equipment was designed for internal thread formed by cold extrusion. The processing equipment can improve the harsh environment in the extrusion area, reduce extrusion temperature and extrusion torque, make lubricant flow into the compress zone easily and reduce the broken of extrusion tap. Firstly, the overall design of the processing equipment was given and the design of the parts was given and described in detail; Secendly, through the Adams dynamics simulation of the processing equipment, vibration displacement curve of vibration plate and angular displacement curve of vibration pole were obtained. The curves show that the processing equipment can provide vibration on the extrusion tap, and realize vibration cold extrusion.
