Description

Technical Field

[0001] The utility model relates to precision processing technology, in particular to stamping and forming, and specifically to a stamping and forming structure of a bearing seat movable adjustment type product. Background Art

[0002] In the field of stamping technology, vertical stamping is one of the common methods. However, due to material problems of some products, such as stainless steel or metal materials with high elasticity, the existing technology uses one-time stamping, which is prone to rebound at the stamping point and low product qualification rate. At the same time, after vertical stamping, the vertically formed part is prone to sinking and getting stuck at the bearing seat.

[0003] Therefore, it is necessary to provide a support seat movable adjustment product stamping forming structure to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a product stamping forming structure with a movable and adjustable bearing seat.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A stamping structure for a bearing seat with movable adjustment.

[0007] It includes a pre-bent bearing seat module, several progressively reduced bearing seat modules, and a vertical bearing seat module with matching tolerances that are arranged in sequence; the pre-bent bearing seat module, several progressively reduced bearing seat modules, and the vertical bearing seat module respectively include a bottom bearing block, and the bottom bearing block is provided with an arc groove, in which a pre-bent bearing seat, several progressively reduced bearing seats, and a vertical bearing seat with matching tolerances are rotatably arranged; the opening angle of the pre-bent bearing seat is 95-100°; the opening angle of several progressively reduced bearing seats docking with the pre-bent bearing seat is 93-94°, and is reduced by 0.5-1° to 90.5° at each level.

[0008] Furthermore, the end of the arc groove has a docking plane, which is used as a downward pressing limit platform for the punch head.

[0009] Furthermore, the pre-bent bearing seat, the plurality of progressively reduced bearing seats, and the vertical bearing seat with final forming matching tolerances are all rotatably arranged on the bottom bearing block via a rotating shaft.

[0010] Furthermore, the bottom bearing block is connected to a pre-bent bearing seat, a plurality of progressively reduced bearing seats, and a vertical bearing seat with a final formed matching tolerance through an elastic holding member.

[0011] Furthermore, the pre-bent bearing seat, the plurality of progressively reduced bearing seats, and the vertical bearing seat with a final formed matching tolerance are provided with a holding connecting column for connecting the elastic holding member.

[0012] Furthermore, there is a pulling position difference between the pulling connecting column and the rotating shaft, and the pulling connecting column is used as a driving column similar to eccentric pulling.

[0013] Furthermore, the bottoms of the pre-bent bearing seat, the plurality of progressively reduced bearing seats, and the vertical bearing seat with a final formed matching tolerance are in an arc shape.

[0014] Furthermore, the pre-bent bearing seat, the plurality of progressively reduced bearing seats, and the vertical bearing seat with final forming matching tolerances are cylindrical, and corresponding opening grooves are set in the bearing area.

[0015] Furthermore, the elastic holding member is composed of a tension spring.

[0016] Compared with the existing technology, the utility model ensures the vertical stamping forming effect and thus the product quality through the preparation structure of bottom movable adjustable pre-forming, gradual opening, short-time pressure holding and final forming. At the same time, after each stamping, the bearing part can movably bounce the vertical forming part to reduce forming jamming. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example:

[0021] See Figure 1-3This embodiment shows a product stamping forming structure with a movable and adjustable bearing seat, including a pre-bent bearing seat module 100, a plurality of progressively reduced bearing seat modules 200, and a vertical bearing seat module 300 with a final forming matching tolerance, which are arranged in sequence; the pre-bent bearing seat module 100, the plurality of progressively reduced bearing seat modules 200, and the vertical bearing seat module 300 respectively include a bottom bearing block 1, and the bottom bearing block 1 is provided with an arc groove, in which a pre-bent bearing seat 101, a plurality of progressively reduced bearing seats 201, and a vertical bearing seat 301 with a final forming matching tolerance are rotatably arranged; the opening angle of the pre-bent bearing seat 101 is 95-100°; the opening angle of the plurality of progressively reduced bearing seats docking with the pre-bent bearing seat 201 is 93-94°, and is reduced by 0.5-1° to 90.5° at each stage.

[0022] The end of the arc groove is provided with a butt joint plane, which is used as a downward pressing limit platform for the punch head.

[0023] The pre-bent supporting seat 101 , the plurality of progressively reduced supporting seats 201 , and the vertical supporting seat 301 with final formed matching tolerances are all rotatably disposed on the bottom supporting block 1 via the rotating shaft 2 .

[0024] The bottom bearing block 1 is connected to a pre-bent bearing seat 101 , a plurality of progressively reduced bearing seats 201 , and a vertical bearing seat 301 with a final formed matching tolerance through an elastic holding member 3 .

[0025] The pre-bent bearing seat 101, the plurality of progressively reduced bearing seats 201, and the vertical bearing seat 301 with a final formed matching tolerance are provided with a holding connecting post 4 for connecting to an elastic holding member.

[0026] There is a pulling position difference between the pulling connecting column 4 and the rotating shaft 2, and the pulling connecting column 4 is used as a driving column similar to eccentric pulling.

[0027] In one configuration, the bottoms of the pre-bent support base 101 , the plurality of progressively reduced support bases 201 , and the final vertical support base 301 with matching tolerances are arc-shaped.
