As further improvement of the utility model, described adjusting locating piece is fixed in the link slot on die shoe surface by adjusting bolt.
As further improvement of the utility model, on described lower bolster corresponding to being provided with lower jacking block in conduit, described lower jacking block lower end is connected with push rod, described push rod passes lower bolster, die shoe successively, on push rod, be fixed with mounting plate, bottom plate, on described push rod, corresponding to the push rod body between mounting plate and bottom plate, be provided with spring, lower sleeve, on described bottom plate, be connected with lower screw mandrel.
As further improvement of the utility model, described upper padding plate and upper mounted plate are fixedly connected on upper bolster bottom by bolt and holding screw.
The utility model compared with prior art, advantage is: the problem that the utility model exists for snap close ring forming device conventional in prior art and special development and Design, by being set, roller matches with punch, rolling friction is changed in the sliding friction producing when producing snap close ring in prior art, effectively avoided impaired problem in snap close ring forming process, guarantee that the snap close ring surface after moulding is bright, round and smooth, keep original performance of material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the horizontal cross-section schematic diagram of roller, snap close ring, punch triplicity face.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, comprise upper bolster 1, punch 2, half slot 2-1, upper padding plate 3, upper mounted plate 4, snap close ring 5, die shoe 6, regulate locating piece 7, the first wallboard 8, lower jacking block 9, push rod 10, mounting plate 11, lower bolster 12, lower block 13, spring 14, bottom plate 15, lower sleeve 16, lower screw mandrel 17, roller 18, fixed axis 19, the second wallboard 20, conduit 21 etc.
As shown in Figure 1 and Figure 2, snap close ring forming device for a kind of automotive lock of the utility model, the upper bolster 1 and die shoe 6 that comprise the effect of cooperatively interacting, described upper bolster 1 bottom is fixed with upper padding plate 3, upper mounted plate 4 successively, punch 2 is fixed on described upper bolster 1, and punch 2 lower ends pass from upper mounted plate 4, die shoe 6 upper surfaces are fixed with lower bolster 12, die shoe 6 upper surfaces are fixed with lower block 13 corresponding to a side end of described lower bolster 12, on lower block 13, be fixed with the second wallboard 20, at die shoe 6 upper surfaces, corresponding to the end side of described lower bolster 12, be provided with and regulate locating piece 7, on described adjusting locating piece 7, be fixed with the first wallboard 8, between described the first wallboard 8 and the second wallboard 20, form conduit 21, on the first wallboard 8 and the second wallboard 20, by a fixed axis 19, rotate and be provided with roller 18 respectively, and the line of centres of two rollers 18 parallels with the surface of lower bolster 12, described punch 2 bottoms are stretched in conduit 21, and after the half slot 2-1 on punch 2 surfaces matches with the groove arranging on roller 18 peripheries, form in the horizontal direction complete circle.
