Plate double-side pressing mould-less incremental forming device

Abstract

A plate double-side pressing mould-less incremental forming device comprises an external support, a moving mechanism and a forming mechanism. The moving mechanism is arranged on the external support. The forming mechanism is placed in the external support and is placed on a sliding table. The forming mechanism carries out mould-less incremental forming on plates through the moving mechanism which comprises a sliding table moving mechanism and a plate clamping frame moving mechanism. A first forming tool head and a second forming tool head are symmetrically arranged on two moving units of the sliding table moving mechanism, so that the two forming tool heads act on the two sides of each plate respectively, by feeding matching of the two forming tool heads, the plates carry out plastic deformation ceaselessly point by point, and accordingly various metal plate parts provided with convex curved faces and concave curved faces at the same time can be manufactured without concave-convex moulds, and compared with a traditional forming mould, the plate double-side pressing mould-less incremental forming device has higher machining flexibility. Meanwhile, the plate double-side pressing mould-less incremental forming device has the advantages of being high in locating and moving precision, stable in track, convenient to operate and low in cost.

Description

technical field [0001] The invention belongs to the field of mechanical processing, in particular to a dieless progressive forming device for sheet metal. Background technique [0002] Usually in traditional production, the manufacture of sheet metal parts with complex curved surfaces needs to be processed with punches and dies. However, the design and manufacture cycle of the punch and the die is long and the cost is high, so this device is suitable for mass production, but not suitable for the production of single small batch parts and the trial production of new product prototype systems. At the same time, the types and complexity of parts formed by traditional molds have great limitations. Moreover, since springback is unavoidable in the sheet metal forming process, in order to compensate the impact of springback on the forming accuracy, it takes a lot of time and manpower to repeatedly correct the die and punch in actual production. Therefore, in order to reduce costs...

Problems solved by technology

[0005] In order to overcome the deficiency that the forming pressure head in the prior art can only be punched and formed in one direction, but cannot form a workpiece with a depression between two high points on the contour surface, the present invention proposes a die-free press for both sides of the sheet metal.
