摘要
偏置曲柄零件是芦苇压缩打包装置中压缩机构的关键零部件,曲柄连杆的弯曲变形会降低压缩机构的寿命,本文针对在40Cr偏置曲柄零件淬火过程中采用传统人工测量和判断方法存在效率低、精确性较差等问题,采用ANSYS Workbench有限元软件的热分析模块,对该零件淬火过程中瞬时温度场及热应力场进行模拟及实验验证的分析,结果表明:本文提出的模拟方法可行,且至淬火结束时零件平均最大残余应力仅为30.24 MPa。这对装置中零件的材料选型以及提高装置的使用寿命具有实际意义。
Offset crank parts are the key components of the compression mechanism in the reed compression packing device.The bending deformation of the crank connecting rod will reduce the life of the compression mechanism.This article aims at the existence of efficiency by using traditional manual measurement and judgment methods during the quenching of 40Cr offset crank parts.Low temperature,poor accuracy and other issues,the thermal analysis module of ANSYS Workbench finite element software was used to simulate and verify the instantaneous temperature field and thermal stress field during quenching of 40Cr offset crank parts.The results show that the simulation method is feasible,and the average maximum residual stress of the part until the end of quenching is only 30.24 MPa.This has practical significance for the material selection of parts in the device and the improvement of the service life of the device.
