我车间加工的导电螺钉,材料为H62T,原工艺为车、铣、去毛刺,单件定额工时为两小时,效率很低。为此,车间组成三结合小组,对这一零件的冷镦工艺进行分析,并决定在6毫米的冷镦机上初镦,再在10吨冲床上终镦,镦出了合格零件,单件工时缩短到8秒钟。在此基础上,我们作了进一步的分析、试验,打破了变形部分毛坯高度大于选用丝杆直径2.5倍时只能采用双击成形的框框,实现
I workshop processing of conductive screws, material H62T, the original process for the car, milling, deburring, single fixed working hours for two hours, the efficiency is very low. To this end, the workshop composed of three combinations of cold heading process for this part of the analysis, and decided to 6 mm cold heading machine upsetting, and then 10-ton punch on the final upsetting upset qualified parts, single Work time shortened to 8 seconds. On this basis, we made a further analysis, test, breaking the deformation part of the blank height greater than 2.5 times the diameter of the selected screw can only use double-click forming frame, to achieve
