Manufacturing method for upper cover product of integrated control system box of hybrid automobile

Abstract

The invention discloses a manufacturing method for an upper cover product of an integrated control system box of a hybrid automobile. The manufacturing method is characterized by including the following steps of a mold process: drawing, reshaping, trimming, bending, and hole punching and hole edge overturning; a first project: punching of a plate material and drawing, and after punching is performed on the plate material, performing drawing of the shape of a product on a same station; a second project: reshaping, shrinking an R angle in drawing, and performing height beating and pressing on the drum height in drawing; performing the following operation through a blanking work station: a third project: trimming and long-shaped hole punching, and cutting off an excess material; performing the following operation through a bending work station: a fourth project: bending, and performing bending operation on a portion, needing bending, on the product; and a fifth project: hole punching andhole edge overturning, and hole punching operation is performed on the product and edge overturning operation is performed on a hole needing edge overturning. The manufacturing method is adopted for solving the product quality problem that the thinning rate is too large during existing machining of products in the type.

Description

technical field [0001] The invention belongs to the technical field of stamping and forming, and in particular relates to a method for manufacturing a cover product of a hybrid vehicle integrated control system box. Background technique [0002] In today's society, cars have become an indispensable means of transportation for families. As the country controls the environment more and more strictly, and there are still many disadvantages of electric vehicles that have not been resolved. Therefore, in order for car manufacturers to reduce the exhaust emissions of cars to At the very least, in order to reduce fuel consumption, many companies have begun to develop gasoline-electric hybrid vehicle powertrains to make their products more attractive and sales better; [0003] The upper cover of the hybrid vehicle integrated control system box is a key component to ensure the integrated control system box of the vehicle. After the cover is installed on the box, the box must be a dus...
