Mold for manufacturing curved part

Abstract

The invention discloses a mold for manufacturing a curved part. The mold comprises an upper mold assembly, a lower mold assembly and a driving member; the upper mold assembly comprises a concave mold,and the lower mold assembly comprises a convex mold for supporting a workpiece material sheet; the driving member can drive the upper mold assembly to move to be close to the lower mold assembly so that the first end of the concave mold can apply force to the bending position of the workpiece material sheet; the concave mold is rotatably connected to an upper mounting assembly of the upper mold assembly, and the rotation center line of the concave mold is parallel to the upper surface of the convex mold; the lower mold assembly further includes an elastic member and a heel block supported onthe elastic member and is configured to be that in the process of moving the upper mold assembly to the lower mold assembly, the second end of the concave mold can press and abut against the heel block, and the rotating center of the concave mold is located between the first end and the second end of the convex mold. The mold can compensate rebound of the curved part, the bending angle of the curved part can be adjusted without disassembling the mold or adjusting the mold during punching, the production efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a mold for making curved parts. Background technique [0002] For parts with curved structures, it is mostly extruded by using a male die and a die with a fixed angle (adapted to the bending angle of the manufactured part). However, due to the springback deformation of curved parts, it is often impossible to achieve the ideal bending angle in actual production. It can only be realized by correcting the angles of the punch and die through repeated trials. In stamping production, if the angle of the bent part needs to change, it cannot be adjusted in time. [0003] Therefore, how to design a mold for making curved parts, which can compensate the springback of the curved parts and adjust the bending angle of the curved parts during stamping, is currently a problem that those skilled in the art need to solve technical problem.
