Sheet metal incremental forming device with hydraulic support and auxiliary heating and forming method thereof

Abstract

The invention discloses a sheet metal progressive forming device with hydraulic support and auxiliary heating, comprising: a container with an upper opening, which can hold liquid; Formed sheet material; a pressure control system, used to introduce liquid into the container, and control the set pressure value of the liquid in the container; a temperature control circuit, used to control the set temperature value of the liquid in the container. The invention also discloses a forming method utilizing the device at the same time. The device and its forming method replace the support model with a liquid with a certain pressure, which can realize the progressive forming of the metal sheet without die, and can greatly improve the problem of uneven deformation of the sheet metal that occurs in the ordinary progressive forming process, and is better Controlling the temperature in the forming process of plastic sheet can simplify the whole process, improve the forming performance of sheet and improve the forming quality of products.

Description

technical field [0001] The invention relates to a sheet material progressive forming processing technology, in particular to a sheet material progressive forming device with hydraulic support and auxiliary heating and a forming method thereof. Background technique [0002] Sheet metal numerical control incremental forming technology adopts the idea of ​​rapid prototyping manufacturing technology "layered manufacturing", driven by CAD model, and adopts existing general CAM technology and equipment to process sheet metal parts of any shape, which is very suitable for processing single pieces Or small batches of thin shell products. [0003] Completely moldless and unsupported incremental forming, that is, negative forming, without any support at the bottom of the sheet, but can only be used to form parts with relatively simple shapes and low precision. If it is necessary to form parts with complex shapes and high precision, it is necessary to add a support model at the bottom...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of sheet metal gradual forming device and its forming method with hydraulic support and auxiliary heating, this device and forming method use the liquid with certain pressure to replace support model, can The realization of dieless incremental forming of metal sheet can greatly improve the problem of uneven deformation of sheet metal in the ordinary incremental forming process, and better control the temperature in the process of plastic sheet forming, thus simplifying the entire process, Improve the forming performance of sheet metal and improve the forming quality of products
