Embodiment Construction

[0015] The present invention will be further described in detail through specific implementation examples below.

[0016] A method for preparing an automobile sheet metal part, characterized in that it comprises the following steps:

[0017] The first step: place the plate body in a vacuum environment, process and shape it through sheet metal technology, and process a rectangular runner groove with a depth of 1.1 cm and a width of 0.6 cm;

[0018] Step 2: Position the board on the workbench, with the back of the board facing up, and the arc-shaped runner groove of the board is exposed. Fix the board on the milling machine with the clamp, and use the milling machine to place the runner groove in step 1. The two opposite side walls are processed into a concave arc shape;

[0019] Step 3: Heat the reinforced body to a molten state, put the raw materials configured with the reinforced body composition into the hopper of the casting machine, mix and heat to a molten state;

Abstract

The invention discloses a manufacturing method of automobile sheet metal parts and belongs to the technical field of automobile materials. The manufacturing method comprises the following steps that a plate is placed in a vacuum environment and molded through a sheet metal technique, and a rectangular runner groove which is 1-3 cm deep and 0.5-1 cm wide is obtained through machining; the two opposite side walls of the runner groove obtained in the first step are machined to be in an inwards concave arc shape through a milling machine; a reinforcer is heated to the molten state; the reinforcer in the molten state is poured into the runner groove; and nitrogen is sprayed to the obverse side of the plate for cooling so that the reinforcer can be solidified. Through the manufacturing method, the problem that manufacturing efficiency of existing sheet metal parts is too low is solved.

Description

technical field [0001] The invention relates to the technical field of automobile materials, in particular to a method for preparing automobile sheet metal parts. Background technique [0002] Sheet metal is a comprehensive cold processing process for metal sheets (usually below 6mm), including shearing, punching / cutting / compositing, folding, welding, riveting, splicing, forming (such as car body), etc. Its remarkable feature is that the same part has the same thickness, and the products processed by sheet metal technology are called sheet metal parts. The frame and door of the car are all made of sheet metal parts. Usually the front of the sheet metal part is exposed to the outside to form the outer surface of the car. (position outside the cab), or in the cab by interior wrapping. Some parts of automobile sheet metal parts are more vulnerable to impact, so some parts need to be reinforced, but because the thickness of the sheet metal parts is uniform, it is not possible ...
