Manufacturing method for windscreen wiper supporting base

Abstract

The invention discloses a manufacturing method for a windscreen wiper supporting base. An integrated reflux strip assembly is placed into a supporting base forming mould, so that a semi-finished product comprising a plastic supporting base and the reflux strip assembly is obtained; a rivet is placed into a riveting lower mould on a loading position of a riveting rotary disc, the semi-finished product is placed into the riveting lower mould and an elastic contact piece is placed onto the semi-finished product; while rotating to the riveting position below a riveting upper mould, the riveting lower mould is matched with the riveting upper mould to complete riveting of the elastic contact piece and the reflux strips; a first punch on a riveting mould is matched with a first punching mould cavity, and a rectangular division hole is punched out in a connecting part, so that reflux strips at the two sides are separated from each other; and when the riveting lower mould rotates to a materialtaking position, a manipulator grabs a product onto a transmission belt. The manufacturing method can realize automatic production of the windscreen wiper supporting base; and meanwhile, the reflux strips are conveniently placed during injection molding, and operations are orderly during riveting, so that labor cost is favorably reduced, and a qualification rate of products is increased.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a method for manufacturing a wiper support which is beneficial to realize automatic production. Background technique [0002] Wiper is an essential component on the automobile, and existing wiper generally comprises a wiper support, is arranged on the electric motor on the wiper support, speed reducer, four-bar linkage, wiper blade rotating shaft, wiper blade etc. When the driver presses the switch of the wiper, the motor starts, and the speed of the motor drives the swing arm after being decelerated by the reducer. Rotate, and finally the wiper blade is driven by the wiper blade rotating shaft to wipe the windshield. For example, "a kind of wiper and vehicle" disclosed in the Chinese patent literature, its announcement number is CN203472809U, the wiper includes a wiper swing arm, a wiper rotating arm, and a washing liquid ejection pipe is arranged on the wiper ...

AI Technical Summary

Problems solved by technology

[0005] The first object of the present invention is to provide a method for manufacturing the wiper support, in order to solve the problems of low degree of automation in the manufacturing process of the wiper support and the difficulty in placing the return strip by the operator when the base is injection molded. It can not only realize the automatic production of the wiper support, but also facilitate the placement of the return bar during injection molding, which is conducive to reducing labor costs and improving the pass rate of products

[0006] The second object of the present invention is to provide a method for manufacturing the wiper support, in order to solve the difficult operation of riveting the elastic contact piece in the manufacturing process of the wiper support, and also prone to misplacement and leakage. It can simplify the operation procedures during riveting, and can effectively avoid the problems of misplacement and omission, so as to reduce labor costs and improve the pass rate of products
