Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] The invention relates to a method for progressive forming of polymer plates based on metal backplate support, which can effectively improve the quality of progressively formed parts of polymer plates, and specifically includes the following steps:

[0025] 1) According to the shape of the polymer part, determine its main forming direction.

[0026] 2) According to the main forming direction of the part in step 1), find out the maximum forming angle of the part Forming angle here is the angle between the normal vector of the processing position and the Z axis.

[0027] 3) Select the metal support back plate according to the material and thickness of the polymer parts. Here, the materi...

Abstract

The invention discloses a high polymer board incremental forming method based on metal backboard supporting. The method has the beneficial effects that firstly, a metal backboard provides effective rigidity and strength supporting for a high polymer board, reverse pressure can be exerted on a high polymer part through forming and rebounding, the stress condition of the high polymer part is effectively improved, and the high polymer part can be effectively prevented from being twisted and deformed partially in the machining process; secondly, the overall twist and deviation of the high polymer part in the forming process can be effectively avoided through the metal backboard; thirdly, the partial necking and thinning of the high polymer machined part can be effectively controlled through the rigidity supporting of the metal backboard, and the thickness of the high polymer machined part can be effectively controlled; and fourthly, the adaptability of an incremental forming process is improved, and application and popularization of the incremental forming technology in machining of the high polymer part are facilitated.

Description

technical field [0001] The invention relates to a method for progressive forming of polymer plates, which belongs to the technical field of progressive forming of polymer plates. Background technique [0002] Incremental Sheet Forming (ISF) is a moldless flexible forming technology proposed by Leszak of the United States in the 1960s. In the 1990s, Matsubara Shigeo of Japan conducted further research on this technology, and gradually attracted the attention of various countries. attention of scholars. Incremental forming technology is an advanced manufacturing technology based on computer technology, numerical control technology and plastic forming technology. Its main feature is the introduction of the idea of ​​"layered manufacturing" in rapid prototyping manufacturing, and the three-dimensional CAD model of complex products along the forming axis The direction is discretized into many section layers, that is, it is decomposed into a series of contour layers, and the proc...
