The outer shape edges of the product after forming are irregular and unstable. When subsequent trimming treatment is required for the outer shape of the product after forming, it is very difficult to clamp and position it, seriously affecting the accuracy of the subsequent trimming process, increasing the production cost, and reducing the production efficiency. Therefore, it is urgent in this field to improve a die forming positioning mechanism to solve the defects of the prior art. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a die forming positioning mechanism, which is convenient for positioning the workpiece after forming, and thus improves the accuracy and efficiency of trimming the formed workpiece in the later stage.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a die forming positioning mechanism, including an upper forming male die and a lower forming male die. The opposite sides of the upper forming male die and the lower forming male die are both provided with adapted forming cavities. The lower forming male die is provided with a plurality of flanging punches, the upper ends of the flanging punches exceed the upper surface of the lower forming male die, a forming hole adapted to the flanging punches is opened on the lower surface of the upper forming male die, and a workpiece is placed on the upper ends of the plurality of flanging punches.

[0005] Preferably, the opposite sides of the upper forming male die and the lower forming male die are respectively provided with an upper die base and a lower die base. The opposite sides of the upper die base and the lower die base are respectively provided with upper cushion feet and lower cushion feet. The opposite sides of the upper cushion feet and the lower cushion feet are respectively provided with an upper support plate and a lower support plate. The plurality of flanging punches are arranged on the upper surface of the lower die base and penetrate through the lower forming male die.

[0006] Preferably, a stepped hole is penetrated through the upper end of each flanging punch, an installation bolt is penetrated through the stepped hole, and a threaded hole adapted to the installation bolt is opened on the upper surface of the lower die base.

[0007] Preferably, a forming ring is threadedly connected to the side surface of the upper end of each flanging punch, and the side surface of the forming ring is arc-shaped.

[0008] Preferably, the aperture of the forming hole is larger than the diameter of the flanging punch, and the depth of the forming hole is greater than the height of the flanging punch leaking out of the upper surface of the lower forming male die.

[0009] Preferably, a forming angle is opened on the inner side wall of the opening end of the forming hole, and the forming angle is arc-shaped and adapted to the outer side surface of the forming ring.
