Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 2, a metal plate bending arc die includes an upper die 10 and a lower die 20 opposite to each other. The upper die 10 comprises an upper die base 11, an upper die core 12 and a locking piece 13.

Referring to fig. 3 and 4, the upper die base 11 is provided with a plurality of connecting portions 111, and is detachably connected to the bending machine through the connecting portions 111. The connecting portion 111 is a protruding stripe bump.

The lower end of the upper die holder 11 is provided with a plurality of mounting grooves 112, and the locking piece 13 is arranged in the mounting grooves 112. A strip-shaped groove 121 is formed in the upper mold core 12, a connecting hole 122 is formed in the strip-shaped groove 121, so that the lower end of the upper mold base 11 extends into the strip-shaped groove 121, and the locking piece 13 extends out of the mounting groove 112 and is detachably connected with the connecting hole 122.

When the upper die needs to be replaced, the locking piece 13 is made to exit from the connecting hole 122, the upper die core 12 is moved to make the lower end of the upper die base 11 exit from the strip-shaped groove 121, and another upper die core 12 is selected to be installed to the original position. Therefore, only the upper mold core 12 needs to be replaced during replacement, so that the material is saved, and the cost is reduced.

The bottom surface of the upper mold core 12 is an arc surface, and the lower mold 20 is provided with a groove 21 opposite to the bottom surface of the upper mold. The upper mold core 12 is of a round bar structure, and the strip-shaped groove 121 extends along the length direction of the upper mold core 12. Wherein the strip-shaped groove 121 is in clearance fit with the lower end of the upper die holder 11.

The groove 21 is a V-shaped groove. The ratio of the maximum width dimension of the groove 21 to the radius dimension of the bottom surface of the upper mold core 12 is at least 3: 1. Specifically, the width of the lower mold 20 is 60 mm. The maximum width dimension of the groove 21 is 50mm, and the radius dimension of the bottom surface of the upper die is R5mm-R15 mm. By making the groove 21 a V-shaped groove, only the upper die core 12 of the corresponding specification needs to be replaced during bending, and the lower die 20 does not need to be replaced, which is highly versatile.

The locking member 13 is embodied as a bolt. The mounting groove 112 is a T-shaped groove. The mounting groove 112 includes a horizontal extension portion 1121 and a vertical portion 1122, and the width of the horizontal extension portion 1121 is greater than the width of the nut of the locker 13 so as to facilitate tightening or loosening of the locker 13 by an open-end wrench.

In the scheme, the upper mold core 12 is made of 42CrMo material, and the hardness of the upper mold core 12 is HRC 45-49. The upper die holder 11 and the lower die 20 are also made of 42CrMo materials, and the hardness of the upper die holder 11 and the hardness of the lower die 20 are HRC 45-49.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
