Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is explained in detail.
An adapter shaft cold-heading molding technique as shown in Figure 1, processing step is:
S1, cut wire rod;
S2, to the little bar of wire rod intense beam;
S3, preformed head be shaping step simultaneously;
S4, preformed head endoporus and by cylindrical for head upsetting pressure;
S5, by the shaping macropore of head endoporus reverse drawing;
S6, at macropore inner counter pulling shaping aperture;
Colored tooth on S7, shaping little bar.
Described wire rod is through work hardening.
The mould structure of forming embossing tooth in a kind of step S7 as shown in Figure 7, comprise punch die unit and main form unit, described punch die unit comprises punch die shell 7, punching pin for punch dies 9 is provided with in the middle part of described punch die shell 7, punch die cushion block 8 is provided with in described punch die shell 7 inside, described punch die cushion block 8 offsets with punching pin for punch dies 9, described main form unit comprises main formwork 10, described main formwork 10 inside is provided with main mould leading portion 11 successively, main mould stage casing 12 and main mould back segment 18, forming hole 13 is provided with at described main mould leading portion 11 and main mould stage casing 12, in the middle part of described main formwork 10, be provided with main mould thimble 16 run through main mould back segment 18 and be communicated with forming hole 13, described main mould back segment 18 inside is provided with the material-receiving device 15 for fixing main mould thimble 16, and preventing main mould thimble 16 from rotating affects forming embossing tooth, described main formwork 10 rear end locks 17 after being provided with main mould, described main formwork 10 is provided with locating slot 14, facilitates mould stationary positioned.
Each station is divided into punch die unit and main form unit as shown in Figure 2 to 7, and punch die unit has punch die shell 1, punch die cushion block 2, punching pin for punch dies 3 forms, and main form unit has main formwork 4, the part compositions such as main mould 5 and main mould thimble 6, wherein cross mould to be completed by clip, all moulds are all contained on cold headers.Punch die unit mass motion and punching pin for punch dies pushes part enters in master cast chamber in the course of the work as shown in Figure 2, main form unit part is fixed on the machine, and main mould thimble motion, plays the effect releasing part.Punch die unit mass motion in the course of the work as shown in Figure 3, punching pin for punch dies and punch die cushion block move in the machine, punching pin for punch dies pushes part and enters shaping head in master cast chamber, main formwork, main mould leading portion, main mould stage casing and main mould back segment are fixed on cold headers, and the effect releasing part is played in main mould thimble activity.Punch die unit mass motion and punching pin for punch dies pushes part enters in master cast chamber in the course of the work as shown in Fig. 4, Fig. 5, Fig. 6 and Fig. 7, main formwork, main mould leading portion, main mould stage casing and main mould back segment are fixed on cold headers, and the effect releasing part is played in main mould thimble activity.
