Forming die for aluminum alloy side impact beam

Abstract

The invention provides a forming die for an aluminum alloy side impact beam, and belongs to the technical field of dies. The forming die comprises an upper die structure, a lower die structure and a forming space, and two ends of the forming space are each provided with a clamping structure, a translation structure and a pressing structure; each clamping structure comprises a guide seat, a pull block is arranged in the guide seat, and two clamping parts capable of relatively moving are mounted at one end of the pull block; each translation structure comprises two oppositely-arranged translation parts, and one ends of the two translation parts extend into the corresponding guide seat and are matched with the other end of the corresponding pull block in an abutting mode; and each pressing structure comprises a first power source used for pressing the pull block downwards and a second power source used for resetting the pull block. By means of the clamping structures and the upper die structure, a product reaches the yield strength before being formed, and then the product is completely formed through the power sources in the pressing structures, so that the springback amount of the formed product is reduced, and the percent of pass of formed products is increased.

Description

technical field [0001] The invention belongs to the technical field of moulds, and relates to a forming die, in particular to a forming die for an aluminum alloy car door anti-collision bar. Background technique [0002] Among the existing alloy materials, the aluminum alloy material has been widely used due to its high strength and high tensile limit, especially for the anti-collision bar of the car door. [0003] However, the aluminum alloy has a large amount of springback during the forming process, and the two ends and the middle of the door anti-collision bar need to be bent. Therefore, the amount of springback of the bent part needs to be considered during the forming process However, because the rebound amount is difficult to accurately control, the defect rate of the formed car door bumper bar increases, resulting in waste of materials. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned problems in the existing t...
