Description

A bearing dust cover stamping die

technical field

The bearing dust cover stamping die involved in the present invention is suitable for stamping small, medium and large bearing dust covers.

Background technique

The traditional bearing dust cover stamping die is integral, and the stamping part of the die is of the same size (designed according to the nominal size of the dust-proof groove). The methods mentioned above all have the following shortcomings:

①The mold is integral, and the stamping part is not movable, so the use of the mold is very inflexible, because the size of the dust-proof groove currently processed is relatively large, and it is difficult for a mold to adapt to the dust-proof groove with such a large dispersion. It is necessary to prepare three sizes of molds (large size, medium size, small size) or even more molds, which increases the production cost of the workshop and reduces the production efficiency;

②It is necessary to roughly divide the size of the dust-proof groove before each stamping, which greatly affects the production efficiency of the workshop;

③Due to the relatively large dispersion of dust-proof grooves and the size and dispersion of each batch of dust-proof grooves are more or less different, it is difficult for the existing molds to cover all the sizes of dust-proof grooves, so that each batch will There are still some bearings with poor stamping of the dust cover, which affects the productivity of the workshop.

Utility model content

The technical problem to be solved by this utility model is to overcome the above-mentioned deficiencies in the prior art and provide a stamping die for bearing dust cover with a new structure.

In order to achieve the purpose of this utility model, the following technical solutions are adopted: a bearing dust cover stamping die, including a main body in the shape of a round tube, the outer wall of the main body is integrally formed with an annular connecting wall coaxial with the main body , the outer periphery of the connecting wall is evenly formed with 3-4 strip-shaped openings along the radial direction of the connecting wall; it also includes the same number of stamping parts as the strip-shaped openings, the stamping parts are arc-shaped, and each stamping part is connected end to end just to form A circular ring, each stamping part is respectively connected to each bar-shaped opening by a screw.

As a preferred solution: the outer edge of the stamping part away from the outer surface of the connecting wall is formed with a stamping bead with a triangular cross-section; the inner edge of the outer surface is formed with a concave ring, and the stamping part is located in the concave ring A threaded connection hole for connecting with the screw is formed at the position; an annular groove concentric with the arc-shaped stamped part is formed at the outer position of the threaded connection hole on the inner surface of the stamped part close to the connecting wall.

Compared with the prior art, the beneficial effect of the utility model is that the stamping abrasive tool for the dust cover of the utility model is composed of several adjustable stamping parts, and different sizes can be adjusted according to the size of the dust-proof groove, reducing The number of original molds is reduced and the number of mold repairs is reduced, which greatly improves the production cost and efficiency of the workshop; at the same time, it also saves the link for the operator to grade the size of the dust-proof groove, which greatly improves the production efficiency; Stamping quality of the dust cap.

Detailed ways

The specific embodiment of the utility model is described in detail below according to the accompanying drawings.

As shown in Figures 1 to 5, a stamping die for a bearing dust cover according to this embodiment includes a main body 1 in the shape of a round tube, and the outer wall of the main body is integrally formed with an annular connection coaxial with the main body Wall 11, the outer periphery of the connecting wall is uniformly formed with four strip-shaped openings 12 along the radial direction of the connecting wall; it also includes the same number of stamping parts 2 as the strip-shaped openings, the stamping parts are arc-shaped, and each stamping part is connected end to end It just forms a circular ring, and each stamping part is connected to each bar-shaped opening 12 by a screw 3 respectively.

The outer edge position of the outer surface of the stamping part away from the connecting wall is formed with a stamping convex ring 21 with a triangular cross-section; the inner edge position of the outer surface is formed with a concave ring 22, and the stamping part is located at the position of the concave ring A threaded connection hole 23 for connecting with the screw is formed; an annular groove 24 concentric with the arc-shaped stamped part is formed on the inner surface of the stamping part near the connecting wall outside the threaded connection hole.

Since the stamping abrasive tool for the dust cover has several adjustable stamping parts, different sizes can be adjusted according to the size of the dust-proof groove, which reduces the number of original molds and reduces the number of mold repairs, greatly improving the workshop efficiency. Production cost and efficiency; at the same time, it also saves the link of the operator to grade the size of the dust-proof groove, which greatly improves the production efficiency; in addition, it also improves the stamping quality of the bearing dust-proof cover.

When in use, connect the screw to the threaded connection hole of the stamping part, place the screw in the strip opening of the main body and lock the screw, so that the stamping part and the main body can be fixed for stamping, and the position of the stamping part needs to be adjusted to adapt to different For the dust cover of the same size, you only need to loosen the screws, move the stamping parts to a suitable position, and then tighten the screws again.
