Abstract

The invention discloses a plate trimming and forming mould and belongs to the technical field of moulds. According to the technical scheme, the plate trimming and forming mould is characterized in that flanging forming surfaces are arranged on a material pressing core and a material supporting core separately, meanwhile, cutting blocks are arranged on the edges of the flanging forming surfaces, two processes of flanging and cutting can be completed in the process that an upper mould part moves towards a lower mould part and finally is in contact with the lower mould part, the rebounding forceof the material pressing core can be adjusted by adjusting the position of a movable positioning plate, and adjustment is performed according to different materials and plate thicknesses, so that thevibration strength during stamping is reduced, the vibration friction force generated when an upper mould knife and a lower mould knife are in contact is reduced, and the service life of a cutter is prolonged. According to the plate trimming and forming mould, the number of workpiece moulds is reduced, the cost of the mould is reduced, the production efficiency is improved, and the mould has the advantages of simple structure and low cost.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a board trimming and forming mould. Background technique [0002] In the manufacturing process of auto parts, a large number of plate parts need to be trimmed and flanged, such as the outer panel of the automobile engine, the body cover panel, the inner panel of the door and the rear floor. In the existing technology, trimming and flanging of the plate requires two processes to complete, and each process needs to use the corresponding trimming mold and flanging mold. Multiple molds not only increase the production cost of the enterprise , but also reduces the efficiency of production. Contents of the invention [0003] The technical problem to be solved by the present invention: Aiming at the problem that the current board trimming and forming process needs to use two processes of trimming and flanging, not only the cost is high, but also the production efficiency i...
