在拖拉机和柴油机的修理中,平垫圈用量大,在没有冲床的情况下,我们制作了一个专用冲压模具,在一吨齿条压力机上冲压,效果很好。冲压模具的上压板9和下托板1各用四个沉头螺钉15与上、下冲模8及3固定。弹簧定位座2与下托板静配合。冲杆12的螺丝固定在压套13上。导向杆6的下端用螺丝装在下冲模上,上冲模可在导向杆上滑动。螺母10可以调整上、下冲模的距离,调整适当后锁紧。冲杆、滑套,上冲模互相滑配。冲头头部、滑套下平面以及上,下冲模的冲压部位均需淬
In the repair of tractors and diesel engines, flat washers large amount of use, in the absence of punch, we have made a special stamping die, stamping on a one-ton rack press, the effect is very good. Stamping die on the plate 9 and the lower plate 1 each with four countersunk head screws 15 and the upper and lower die 8 and 3 fixed. Spring positioning seat 2 and the lower pallet static fit. The screw of the punch rod 12 is fixed on the pressure sleeve 13. The lower end of the guide rod 6 is screwed on the lower die, and the upper die can slide on the guide rod. Nut 10 can be adjusted up and down the distance between the die, adjust the appropriate lock. Punch, sliding sleeve, the die slide with each other. Punch head, sliding sleeve under the plane and the stamping parts of the upper and lower die must be quenched
