A pickling-free process of folding in half for the processing of turn signal contact pieces

Abstract

The invention discloses a fold in half acid picking free technology for steering lamp contact chip machining. The fold in half acid picking free technology comprises the following steps that (1), moldmachining and shaping are conducted; (2), lineation processing at the fold position is carried out; (3), folding machining is carried out; and (4), detection and examination are carried out. The invention provides a technical scheme of fold in half acid picking free technology for steering lamp contact chip machining, through design of chamfer adding technology, sharp corners are free of collision and extrusion during rotating, copper scales do not occur, and sequential acid picking processes are not required; and through design of a fold in half device, folding of a product can be more automatic, accuracy and quality of folding are improved, and defective rate is lowered.

Description

technical field [0001] The invention relates to a half-fold pickling-free process for processing the contact sheet of the turn signal. Background technique [0002] The turn signal contact sheet is an important part in the automobile turn signal. The existing turn signal contact sheet needs to go through a variety of processing techniques, and the half-folding process is a common process for the turn signal contact sheet processing. However, in the actual double-folding process of the existing turn signal contact piece, if there is a sharp corner at the half-fold, then in the process of folding and rotating 180°, the sharp corner will collide and squeeze, which will cause copper shavings For the production of copper wire, after the half-folding process, it is necessary to carry out the process of pickling to remove the copper wire to ensure the quality, increase the process steps, and increase the production cost. Moreover, in the process of folding the existing turn signal...

Problems solved by technology

However, in the actual double-folding process of the existing turn signal contact piece, if there is a sharp corner at the half-fold, then in the process of folding and rotating 180°, the sharp corner will collide and squeeze, which will cause copper shavings For the production of copper wire, after the half-fold treatment, it is necessary to carry out the process of pickling to remove the copper wire to ensure the quality, increase the process steps, and increase the production cost.

Moreover, during the process of folding the existing turn signal contact pieces, the folding line is prone to deflection, which affects the quality of the folding and increases the rate of defective products.
