当产品零件结构为圆形板件,厚δ=1～6mm,虽其精度要求不高,但由于缺乏圆落料模下料和机加工不好装夹等原因,往往使操作者为加工而犯愁。这里介绍一简易可行的加工方法:(1)先把钢板落料成正方形或正多角形;(2)进行校平;(3)车制一带顶尖孔的圆压板(其压紧用平面与顶尖孔中心应垂直)再按如图示的压紧法(用活顶尖顶紧)即可进行切削加工。若用切环槽落料时,可先切至距工件平面约0.1～0.25mm时把
When the structure of the product parts is a circular plate, the thickness δ = 1 ~ 6mm, although its accuracy is not demanding, but because of the lack of circular blanking die cutting and machining is not good folder and other reasons, often make the operator for processing worry. Here is a simple and feasible method of processing: (1) the first sheet of steel blanking into a square or regular polygon; (2) leveling; (3) car with a round hole with the top plate (the pressing plane and the top Hole center should be vertical) and then press the compression method as shown (with the living top sharp tight) can be cut. If you use cutting ring slot blanking, you can cut to the workpiece plane about 0.1 ~ 0.25mm when put
