[0029] Example 1

[0030] Referring to Figure 3 and Figure 4 , a stamping part bending and shaping jig set includes a shaping jig and a sand blasting jig, the shaping jig includes: a shaping jig base, a shaping jig lower steel plate, a shaping and bending jig upper steel plate, and a plurality of support columns, a plurality of positioning columns, and a plurality of boss structures; the sand blasting jig includes: a sand blasting jig base plate and a sand blasting jig cover plate.

[0031] Referring to Figure 7 and Figure 8 ​, the 36 boss structures are designed on the base of the shaping fixture, each boss structure corresponds to a product, the top surface of the boss structure is designed according to the profile of the inner cavity of the product, and the boss structure can stably support the product; the single-side gap between the boss structure and the skirt structure of the product is 0.2mm, the safety gap ensures that the boss structure effectively limits the product, and also ensures that the product does not easily appear "stuck" phenomenon when the disc is clamped; the lower steel plate of the shaping fixture, the main function of the steel plate is: at the middle hand position of the fixture, the lower steel plate of the shaping and bending fixture is pushed upward by two hands and four fingers, the steel plate pushes the "wings" on both sides of each product to bend according to the designed size; because the shaping and bending fixture set is used in a sandblasting workshop environment, when the product and the fixture base are "stuck" due to sand particles, the self-weight of the lower steel plate of the fixture can generate a pushing force on the 36 products, so that the products can be smoothly turned to the sandblasting fixture. The lower steel plate has corresponding avoidance holes and multiple weight reduction holes according to the 36 boss structures of the shaping fixture base; the upper steel plate of the shaping and bending fixture, the main function of the steel plate is: at the middle hand position of the fixture, the upper steel plate of the shaping and bending fixture is pressed by two thumbs, and the support column limits the steel plate, the steel plate can be pressed on the upper part of the "wings" of each product, the designed gap between the product and the steel plate is 0.25mm, which limits the bending of the product, and cooperates with the lower steel plate to complete the shaping operation of the product. The upper steel plate of the shaping fixture has corresponding avoidance holes and multiple weight reduction holes according to the 36 boss structures of the shaping fixture base.

[0032] Referring to Figure 14 and Figure 15 , the support column has the main function of limiting the lower steel plate of the shaping fixture in "X / Y" direction, supporting the middle position of the upper steel plate of the bending and shaping fixture, limiting the upper steel plate in "Z" direction, and the height of the support column determines the position of the product bending line; the positioning column has the main function of limiting the upper steel plate of the shaping fixture in "X / Y" direction, supporting the four corners of the upper steel plate of the shaping fixture, the size of the step is the same as that of the positioning column, and the two kinds of positioning columns are used in cooperation to limit the upper steel plate in "Z" direction.

[0033] Referring to Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13, sand blasting jig bottom plate, its main role is the largest area to support the product, and the product is limited, to prevent the product in the sand blasting process in a large range of shaking, and prevent the product sanding when the stress deformation is not good; sand blasting jig cover plate, its main role is to cooperate with the sand blasting jig bottom plate to limit the product, to prevent the product in the sand blasting process in a large range of shaking, and prevent the product sanding when the stress deformation is not good; product in Y direction through the edge of the sand blasting jig bottom plate limit, product and sand blasting jig bottom plate design gap 0.4mm, product X direction through the edge of the sand blasting jig bottom plate limit, product and sand blasting jig bottom plate design gap 0.2mm, the above design is to prevent the product sanding when the stress deformation, the product is supported to the product maximum area.
