Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] refer to Figure 2-Figure 9, when this method is concretely implemented, comprise the following steps: a, drawing, promptly adopt drawing die, the plate shape blank of rectangle is processed into the first semi-finished product, the structure of the first semi-finished product refers to Figure 8 , in which all the external structures of two symmetrical components have been formed in the middle of the rectangular plate blank, and the two ends of the two components are bent relative to each other (the drawing in step a belongs to the mature existing processing technology, the drawing die It can be a lower mold and an upper mold, and the component cavity can be obtained after the lower mold and the upper mold are closed. The component cavity is formed after the ring is closed); b, (refer to figure 1 and Figure 8 ) using a tri...

Abstract

The invention discloses a method for pressing inner skins of front pillars. The method is implemented through the steps of drawing the shape of a product in place by one step with a drawing die, then, carrying out punching and edge cutting and trimming on the product by using an edge cutting die and a cutting-off die, so that processing on the shape and all holes and edges of the product can be completed just through three steps. Therefore, the method disclosed by the invention solves the problems in the prior art, improves the utilization ratio of materials, shortens the procedures, and reduces the times of product rotating and clamping and the number of production equipment; and multiple procedures are completed through one time clamping operation, thereby simplifying the processing step, improving the processing efficiency, reducing the manpower cost, and guaranteeing the product quality and the product stability.

Description

technical field [0001] The invention relates to a microcar component processing technology, in particular to a method for processing the inner skin of a front pillar of a miniature car. Background technique [0002] Mini-cars generally refer to A00-class cars in A-type cars. The wheelbase of this kind of car is generally between 2 meters and 2.2 meters (some models are outside this range), and the engine displacement is generally less than 1 liter. [0003] The front column of the miniature car refers to the support in front of the cab of the miniature car to support the roof of the cab. [0004] An existing inner skin component of a front pillar of a miniature car has a structure such as figure 1 As shown, it is a long plate-like shape with both ends slightly bent backwards (when describing the direction of the component in this manual, the actual installation state of the product component is used as the orientation reference, such as the front side of the component The ...
