Problems solved by technology

However, for different sheet metal parts, auxiliary mold bases and clamping devices that form a one-to-one correspondence with the features to be formed are often required, that is, a forming tool that matches the formed part is required. The existing forming tools are poor in interchangeability and are likely to cause Idle or abandoned, resulting in waste of resources

Abstract

The invention relates to a flexible clamping device for single-point incremental forming of sheet metal and a forming method. The flexible clamping device comprises a bottom plate, a plurality of clamping modules and a plurality of adjustable supporting modules, wherein the clamping modules and the adjustable supporting modules are detachably connected with the bottom plate. Mounting holes which are arranged in a matrix are formed in the bottom plate. The plurality of adjustable supporting modules are fixed on the upper surface of the bottom plate through the mounting holes and can be adjustedin height. The plurality of clamping modules are fixed on the upper surface of the bottom plate through the mounting holes and distributed at the peripheries of the adjustable supporting modules forclamping the sheet metal. Compared with the prior art, the flexible clamping device can be used for rapidly and accurately clamping the sheet metal and can be randomly combined according to the characteristics of a formed sheet metal part to generate a supporting structure for incremental forming; and the flexible clamping device has the functions of flexible clamping and flexible back mold.

Description

technical field [0001] The invention relates to the field of single-point progressive forming technology, in particular to a flexible clamping device and forming method for single-point progressive forming of sheet material. Background technique [0002] With the diversity of product requirements and changing market demands, the application of individualized, customized and small-batch sheet metal parts manufacturing is becoming more and more extensive. Due to the high mold cost and long development and manufacturing cycle, the traditional sheet metal stamping is not suitable for small batch production and new product development. Sheet metal incremental forming technology is a highly flexible new sheet metal plastic forming technology. It uses a computer to control a rigid tool head with a certain fillet radius, and moves along the set processing track to make the sheet gradually produce local plasticity. Deformation, the desired shape of the sheet metal product can be obt...
