Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A cold-heading molding technique for car door lock shaft as shown in Figure 1, described processing step is:
S1, cut wire rod;
S2, contracting bar is carried out to the both ends of wire rod;
S3, for the first time pre-upsetting ledge structure;
The pre-upsetting step of S4, second time and contracting bar;
S5, shaping step and chamfering;
S6, forming embossing tooth, shaft flange and groove.
Described wire rod is through work hardening.
The mould structure that in a kind of step S6, lock shaft is shaping as shown in Figure 6, comprise main form unit and punch die unit, described main form unit comprises main die sleeve 14, main die is provided with in described main die sleeve 14 inside, main mould thimble 18 is provided with in described main die center, described punch die unit comprises punch die cover 10, overlap 10 heads at described punch die and be provided with punch die benevolence 13, in the middle part of punch die cover 10, be provided with punching pin for punch dies 9 run through punch die benevolence 13, described main die comprises main mould epimere 15, main mould stage casing 16 and main mould hypomere 17, main die-cushion block 19 is provided with below described main mould hypomere 17, described main mould thimble 18 bottom is provided with main mould push rod 20 and offsets with main mould thimble 18, be provided with punch die cushion block 8 bottom the punching pin for punch dies 9 that described punch die overlaps 10 inside, bottom described punch die benevolence 13, be provided with die cushion block 11 be fixed on punch die cover 10, described punching pin for punch dies 9 runs through die cushion block 11 and punch die benevolence 13, described punch die benevolence 13 periphery and punch die are provided with die between overlapping 10 and overlap 12, described main die-cushion block 19 inside is provided with the positioner 21 preventing main mould push rod 20 from rotating, described main die sleeve 14 rear end locks 22 after being provided with main mould, described main mould thimble 18 comprises head and bar portion, described punching pin for punch dies 9 comprises head and bar portion.
