a bending mold

Abstract

The invention discloses a bending mold which comprises an upper mold and a lower mold, wherein the lower mold comprises a lower mold base, a lower convex mold arranged on the lower mold base and two rotating plates positioned beside two sides of the lower convex mold; and the upper mold comprises an upper mold base, a driving device, an upper convex mold arranged on the lower side of the upper mold base, and two pressing parts positioned beside two sides of the upper convex mold. Two pressing parts are arranged on the driving device, the two pressing parts are arranged corresponding to the tworotating plates and are in driving connection with the driving device, when being pressed down to a plate to be bent by the upper convex mold, the two pressing parts are driven downwards by the driving device to the two rotating plates, and the rotating plates are pushed to rotate to press down the plate to be bent, and the two pressing plates can be adjusted transversely to adjust the bending molding angle of the bending mold, so that the problem that the bending mold needs to be redesigned when parts of different bending angles are processed is solved, the production cost is greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a bending mold. Background technique [0002] Bending is a processing method that bends various metal blanks into a certain angle, curvature and shape through molds and presses. It is one of the commonly used process methods for sheet metal stamping. Springback is one of the common phenomena in the bending process. As a result, the bending radius and bending angle of the part are inconsistent with the mold size, and the springback value is closely related to the material of the part. The forming angle of the existing bending die is fixed. For parts of the same material, only a fixed angle can be bent, which will cause the following two problems: (1) Once the bending angle of the part design changes, it needs to be redesigned Manufacture a pair of molds; (2) Considering the springback factor, in order to obtain bending parts with qualified angles, it is often necessary to trial-man...

AI Technical Summary

Problems solved by technology

The forming angle of the existing bending die is fixed. For parts of the same material, only a fixed angle can be bent, which will cause the following two problems: (1) Once the bending angle of the part design changes, it needs to be redesigned Manufacture a pair of molds; (2) Considering the springback factor, in order to obtain bending parts with qualified angles, it is often necessary to trial-manufacture a variety of molds with different angles and carry out trial punching to finally determine the mold forming angle that meets the angle requirements of qualified parts, and Once the material of the part changes, its springback value will change, and it is necessary to redesign and manufacture a pair of molds

This will increase the cost of the mold design and manufacturing process and reduce efficiency
