A continuous flexible incremental forming processing device and method for sheet metal

Abstract

The invention discloses a continuous flexible progressive forming processing device and method of a plate, which solves the problem in the prior art that the continuous flexible progressive forming process of the plate cannot be realized because the processing fixture needs to be continuously disassembled and assembled to clamp the plate. Its technical solution is: comprising a conveying device, a clamping device, a vertical adjustment device, a longitudinal adjustment device and a cutting device. The transmission device is fixed on the front and rear vertical plates through the short axis, and the front and rear vertical plates are installed on the longitudinal adjustment device; there are four clamping devices, which are respectively installed in four directions, front, rear, left, and right. Each clamping device consists of upper and lower parts. Composition, the front and rear clamping devices are connected with the longitudinal adjustment device through the vertical adjustment device, and the cutting device is installed on the left clamping device; the transmission device and the front and rear clamping devices can move forward and backward through the longitudinal adjustment 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.
