Abstract

The invention discloses an aluminium alloy plate press forming method, and relates to the technical field of machining. The method comprises the following steps that an aluminium alloy plate is heated, the heating temperature is controlled to be 495-500 DEG C, and heat insulation is conducted for 30-60 minutes; after heating, the aluminium alloy plate is transferred to water of 75-85 DEG C within 20 s, and after cooling, press forming is conducted within eight hours; before pressing, the surface of a press die and the surface of the aluminium alloy plate are evenly coated with press oil; in the pressing process, the deforming temperature of pressing is controlled to be 250-290 DEG C, the deep drawing speed is 0.2-2 mm / s, and the edge pressing force is 2-3.5 N / mm<2>. According to the aluminium alloy plate press forming method, compared with the prior art, the problem that scratches, deformation and cracking can happen easily in the press forming process of the aluminium alloy plate is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a stamping forming method of an aluminum alloy plate. Background technique [0002] Aluminum alloy has the characteristics of low density, good plasticity, and strong corrosion resistance. Its resources are relatively abundant, and it can be processed into various profiles and plates, and has been widely used in industry. However, in the existing stamping and forming production of aluminum alloy sheets, scratches, deformations, and even sheet breakages often occur, resulting in failure of forming, low product qualification rate, and waste of raw materials. Contents of the invention [0003] The purpose of the present invention is to provide a stamping forming method of an aluminum alloy plate, which can solve the problems of easy abrasion, deformation and cracking in the stamping forming of an existing aluminum alloy plate. [0004] In order to solve the above-me...
