Bending mold

Abstract

The invention relates to a bending mold. The bending mold comprises a lower mold assembly and an upper mold assembly parallel to the lower mold assembly. The lower mold assembly includes a lower moldbase, a forming block connected to the lower mold base and a bending push block slidably connected to the lower mold base. The upper mold assembly includes an upper mold base, a slotting tool slidablyconnected to the upper mold base and an adjusting block slidably connected to the upper mold base. One end of the slotting tool extends out of the upper mold seat and extends toward the lower mold seat to drive the bending push block to slide toward the forming block. The adjusting block is slidably disposed on the upper mold base and one end of the adjusting block extends to the outer side of the upper mold base. The adjusting block is slidably connected with the slotting tool to adjust the amount of extension of the slotting tool relative to the upper mold base. According to the bending mold, in the mold-testing process, by adjusting the adjusting block without modifying the angle of a forming part in the mold, the purpose of adjusting the bending angle of a product can be achieved, themold machining cost can be reduced, and the development cycle of the mold can be shortened.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a bending die. Background technique [0002] In the product manufacturing process, the bending process of the product is sometimes involved, that is, the bending deformation of the product is forced to produce a preset angle by applying force to the product. The problem with the current bending process is that most metal products will rebound at the bend after bending. For example, if figure 1 As shown, in order to bend the product 200 into a right angle, the traditional method is to bend the product 200 into a right angle in a bending mold. However, when the product 200 is out of the mold, the bend will rebound, that is, the end of the bend will rebound from the M1 position to the M2 position when the mold is out, so that the product 200 after the mold out cannot meet the right angle requirement. [0003] For the problem of rebound, the corrective method adopted...

The current problem in bending processing is that most metal products will rebound at the bend after bending

The problem with this approach is that the bending angle calculated by using the rebound rate is a theoretical value, and there will be errors between the theoretically calculated bending angle and the actual processing. Therefore, for the traditional bending angle Bending mold, even if the required bending angle of the product in the bending mold is calculated through the rebound rate, it is still necessary to carry out multiple mold trials in actual operation, and each mold trial must re-modify the molded parts in the mold Angle, resulting in increased mold processing costs, and prolong the mold development cycle
