Problems solved by technology

[0003] Flanging is a common production process in current production. During the flanging process, the requirements for its precision are very high. Ordinary processing methods often cause the size and angle to be unguaranteed, resulting in product scrapping, thereby increasing The production cost is increased, and the production efficiency is low, which basically cannot meet the production process of the workpiece

Embodiment 1

[0046] Embodiment 1: as figure 1 As shown, a flanging fixture includes a lower die 1 , an upper die 2 , a first punch 3 and a second punch 4 .

[0047] The lower mold 1 is a cuboid. The lower mold 1 includes a first mounting surface 11 and a first flange hole 12 . Wherein, the installation surface includes four upright posts 13 , and the upright posts 13 are arranged at four corner ends of the cuboid lower mold 1 . The first flanging hole 12 is provided in the middle of the lower mold 1. For the convenience of description, in this embodiment, the flanging hole is a cuboid. The first mounting surface 11 is a plane.

[0048] This upper mold 2 is also a cuboid. The upper mold 2 includes a second mounting surface 21 and a second flange hole 22 . Wherein, the second installation surface 21 is opposite to the first installation surface 11 , and the size and shape of the first burring hole 12 are consistent with the size and shape of the second burring hole 22 . The second moun...

Embodiment 2

[0053] Example 2, such as Figure 2 to Figure 7 As shown, a flanging method using a flanging jig includes the following steps.

[0054] S01: Fix the flanged sheet metal part 5 between the first installation surface 11 and the second installation surface 21 .

[0055] S02: Press the first punch 3 into the second flange hole 22 .

[0056] S03: using the first punch 3 to punch holes.

[0057] S04: Take off the upper mold 2, and turn over the surface of the sheet metal part 5.

[0058] S05: Utilize the second punch 4 to punch the raised edge of the sheet metal part 5 .

[0059] Further, the step S05 includes the following steps:

[0060] S051: Use the stamping part 42 of the second punch 4 to punch the turned-up side of the sheet metal part 5, so that the turned-up side is inclined outward.

[0061] S052: Use the plane of the limiting portion 41 of the second punch 4 to punch the inclined edge to complete the flanging.

Abstract

The invention provides an edge turning jig. The jig comprises a lower mold, an upper mold, a first punch and a second punch, wherein the lower mold comprises a first mounting surface and a first edge turning hole; the upper mold comprises a second mounting surface and a second edge turning hole; the second mounting surface is opposite to the first mounting surface, and the first edge turning hole is consistent with the second edge turning hole in size and shape; the first punch is used for punching holes for the first time and is fit with the first edge turning hole or the second edge turning hole in size and shape; the second punch is used for punching holes for the second time and turning edges; during hole punching, a sheet metal part is closely pressed between the first mounting surface and the second mounting surface; the first punch punches in the second edge turning hole and the first edge turning hole; and during edge turning, the punched sheet metal part is reversely fixed to the first mounting surface, and edge turning is performed on the sheet metal part by the aid of the second punch. The invention further discloses an edge turning method using the edge turning jig.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a flanging jig and a flanging method thereof. Background technique [0002] With the development of industry, there are many types of mold products and they are complicated. For small batches and complex products, how to flang is a difficult problem to solve. [0003] Flanging is a common production process in current production. During the flanging process, the requirements for its precision are very high. Ordinary processing methods often cause the size and angle to be unguaranteed, resulting in product scrapping, thereby increasing The production cost is increased, and the production efficiency is low, which basically cannot meet the production process of the workpiece. [0004] Therefore, in view of the above problems, it is necessary to develop a new type of flanging fixture, especially a flanging fixture for sheet metal parts. Contents of the invention [0005] The first objec...
