Plate continuous flexible incremental forming machining device and method

Abstract

The invention discloses a plate continuous flexible incremental forming machining device and method, and solves the problems that in the prior art, a machining clamp needs to be continuously disassembled and assembled to clamp a plate during machining, and continuous flexible incremental forming machining of the plate cannot be achieved. According to the technical scheme, the device comprises a conveying device, clamping devices, a vertical adjusting device, a longitudinal adjusting device and a cutting device. The conveying device is fixed to front and back vertical plates through short shafts, and the front and back vertical plates are installed on the longitudinal adjusting device. The four clamping devices are installed in the front direction, the rear direction, the left direction and the right direction respectively. Each clamping device is composed of an upper part and a lower part, the front clamping device and the rear clamping device are connected with the longitudinal adjusting device through the vertical adjusting device, and the cutting device is installed on the clamping device on the left side. The conveying device and the front and back clamping devices can move front and back through the longitudinal adjusting device.

Description

technical field [0001] The invention relates to the field of sheet material forming processing, in particular to a sheet material continuous flexible progressive forming processing device and method. Background technique [0002] Sheet metal incremental forming technology is based on the idea of ​​"layered manufacturing" of rapid prototyping technology. It is an emerging flexible forming technology that can process non-rotating complex curved surface parts without using molds in the forming process. Using flexible progressive forming technology, the processing program can be directly derived from the three-dimensional model of the part, and the part can be formed on the numerical control operating device such as the CNC machine tool without using a mold or a special mold. The development time and economic cost of development are much lower than traditional stamping or forming. technology. [0003] Sheet metal progressive forming technology is a plastic processing technology...

AI Technical Summary

Problems solved by technology

[0004] The inventors found that during incremental forming, the plate to be processed needs to be clamped by blank holders and support plates and fixed on a special fixture device. When the existing incremental forming device processes products with a medium batch or above, it needs to be continuously disassembled. The processing fixture clamps the plate and removes the processed plate, which is inefficient and cannot meet the needs of continuous flexible progressive forming of the plate. It is a waste of time and inconvenient to take the processed plate, which is not conducive to the variable batch processing of the plate.
