Detailed Description

The structure of the flanging die of the present invention will be further described below with reference to specific embodiments to help those skilled in the art to understand the technical solution of the present invention more completely, accurately and deeply.

Example 1

As shown in fig. 3 to 5, the flanging die structure of the present embodiment includes a lower die holder 40, an upper die holder 50, a punch insert 10, a die insert 70, a flanging ejector 30, and a swager 60. The male die insert 10 and the flanging ejector 30 are arranged on the lower die holder 40, the male die insert 10 is positioned on one side of the upper part of the lower die holder 40, the flanging ejector 30 is positioned in the middle of the lower die holder 40, the other side of the upper part of the lower die holder 40 is provided with a lower die holder lateral-preventing part 80, and the lower die holder 40 and the lower die holder lateral-preventing part 80 are of an integrally formed structure. The swager 60 is provided on the punch insert 10. The upper end of the die insert 70 is an installation surface 71, one side of the lower end of the die insert 70 is provided with a flanging die opening surface 72, and the other side of the lower end of the die insert 70 is provided with a die insert anti-lateral surface 73; the mounting surface 71 of the die insert 70 is arranged at the lower part of the upper die holder 50; the flanging module surface 72 of the die insert 70 is arranged opposite to the flanging ejector 30. The die insert anti-lateral surface 73 is attached to the lower die holder anti-lateral part 80. The upper die holder 50 and the material pressing device 60 are arranged side by side.

The embodiment changes the flanging die insert structure on the basis of the background technology, increases the reverse lateral force structure, and is used for offsetting the lateral force generated in the punching flanging process, thereby enabling the flanging of the high-strength steel material product to eliminate flanging rebound, improving the flanging quality, ensuring the flanging precision of the product, and meeting the requirement of the quality of the vehicle body. Specifically, as shown in connection with FIG. 4, the lateral forces generated by the die insert 70 are transmitted to the die insert side guard surface 73, where they are offset by the lateral forces of the lower die holder side guard portion 80. The process avoids the deformation of the die insert 70 caused by the lateral force and controls the change of the flanging gap, thereby reducing the resilience of the flanging position of the part and ensuring the flanging size of the part.

For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial modifications are possible within the protection scope of the present invention as long as the method concept and technical solution of the present invention are adopted.
