Machining method for fixed angle plate of automobile instrument skeleton beam

Abstract

The invention relates to a processing method for a fixed angle plate of an automobile instrument skeleton beam, comprising the following steps of: firstly, coining: stamping raw materials with a coining mould and a press machine, to get a workpiece A; secondly, edge scraping and punching: carrying out edge scraping and punching on the workpiece A with a trimming and punching mould and the press machine, to get a workpiece B; thirdly, first turnuping: turning up the side of the workpiece B with a first turnuping mould and a punching machine, to get a workpiece C; fourthly, first lead deep punching: punching the workpiece C with a first lead deep punching mould and the punching machine, to get a workpiece D; fifthly, secondary lead deep punching: punching the workpiece D with a second lead deep punching mould and the punching machine, to get a workpiece E; sixth, secondary turnuping: turning up the workpiece E with the second turnuping mould and the punching machine, to get a workpiece F; seventhly, small ear bending: punching the workpiece F with a small ear bending mould and the punching machine, to get a workpiece G; and eighthly, waist hole punching: punching the workpiece G with a waist hole punching mould and the punching machine, to get a workpiece H.

Description

technical field [0001] The invention relates to a processing method of an automobile part, in particular to a processing method of a fixed angle plate of an automobile instrument panel skeleton beam. Background technique [0002] At present, the metal reinforcement used for the instrument panel of the front cabin of a car is mainly fixed together by welding of skeleton beams, mounting columns, mounting plates, and mounting brackets. Since the installation column, the installation plate and the installation bracket are all installed on the beam, the structure of the beam is particularly complicated. [0003] Among them, regarding the fixed angle plate of the skeleton beam of the automobile instrument panel, due to its complex shape and complicated process method, its manufacturing cost is relatively high, and it does not meet the needs of market competition. Contents of the invention [0004] In view of the above problems, the object of the present invention is to provide ...
