Problems solved by technology

In the bending process, it is necessary to ensure that the surface of the bent part is clean and free of scratches, which is usually an important precision requirement item for the bent part. However, during the working process of the bending die in the prior art, due to friction between the workpiece and the surface of the die, or More or less, it will damage the surface of the curved parts, reduce the quality of the workpiece, and affect the shape and dimensional accuracy of the workpiece

Embodiment 1

[0017] Embodiment 1: The thickness of the anti-wear protective layer 8 is 0.3mm, and the included angle of the V-shaped part 3 of the concave mold is set to 88°, taking into account the rebound angle of the workpiece.

Embodiment 2

[0018] Embodiment 2: The thickness of the anti-wear protective layer 8 is 0.5 mm, and the included angle of the V-shaped part 3 of the concave mold is set to 87°, taking into account the rebound angle of the workpiece.

[0019] The working process of the anti-workpiece wear-resistant die of the present invention is as follows: first, the die and the supporting punch are installed on the bending die, and installed on the workbench, and then the bending die is equipped with a suitable press; The blanked workpiece to be bent is put into the die and positioned by the positioning block installed on the die. When the mold is working, the punch goes down with the press. When the punch contacts the workpiece, the workpiece starts to bend under the pressing of the punch until the workpiece touches the top piece set in the chute in the middle of the die, and then The block and the die work together to compress the workpiece. The return stroke of the press goes up, and the punch goes up...

Abstract

The invention discloses a female die capable of preventing a workpiece from being abraded. The female die comprises a cuboid-shaped female die body. A rectangular step portion, a female die V-type portion, a sliding groove and a material jacking block mounting groove are formed in the middle of the female die body from top to bottom. Small screw holes and small pin holes for allowing locating blocks to be mounted are formed in the rectangular step portion. An abrasion preventing protection layer is arranged on the surface of the female die V-type portion. Screw holes and pin holes for allowing fasteners to be mounted are further formed in the female die body. The female die is applied to a bending die, the workpiece can be effectively prevented from being scratched in the bending procedure machining process, the precision of the finished workpiece is improved, and production quality is guaranteed.

Description

technical field [0001] The invention relates to a mold used for processing hinge gaskets, in particular to a concave mold for a bending mold which can effectively prevent workpieces from being worn during the bending process. Background technique [0002] The bending process is a stamping process that bends the blank into a certain angle and a certain shape of the workpiece through a mold and a press according to the shape of the part. attached figure 1 The middle hinge gasket is shown. This part is a typical V-shaped part. The shape and structure of the workpiece are relatively simple and symmetrical. It is usually mass-produced. This part mainly has two processing procedures: punching and bending. In the bending process, it is necessary to ensure that the surface of the bent part is clean and free of scratches, which is usually an important precision requirement item for the bent part. However, during the working process of the bending die in the prior art, due to frictio...
