Notebook computer shell anti-cracking rounding forming process

Abstract

The invention relates to the technical field of notebook computer shell forming processes, in particular to a notebook computer shell anti-cracking rounding forming process. The defects in the prior art are solved; and the notebook computer shell anti-cracking rounding forming process comprises two groups of molds, namely a first mold and a second mold. The notebook computer shell anti-cracking rounding forming process comprises the following steps that S1, an aluminum plate is placed in a first mold, and 90-degree right-angle sides are formed at the four corners of the aluminum plate; S2, thestamped aluminum plate is placed in the second mold, and a stamping push block stamps the right-angle sides in the direction of 40-50 degrees, so that the right-angle sides are bent in a scattered mode; and S3, cutting treatment is conducted on the stamped aluminum plate, excessive metal at the corners is removed, and round edges are formed at the corners. Through the adoption of the inclined direction stamping forming process, after the 90-degree right-angle sides are formed through one-time stamping forming, the right-angle sides are stamped from an angle ranging from 45 degrees to 50 degrees through the molds, so that metal sheets of the right-angle sides are bent in a scattered mode, cracking cannot be caused, and the areas of the finally-formed round edges are large.

Description

technical field [0001] The invention relates to the technical field of notebook shell forming technology, in particular to a notebook shell anti-cracking round forming process. Background technique [0002] Stamping processing is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet to deformation force and deform in the mold, so as to obtain product parts of a certain shape, size and performance. Sheet metal, mold and equipment are the three elements of stamping processing. According to the stamping processing temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet metal processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineerin...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the length of the rounded corners of the notebook shell is short, and the protection of the internal components of the notebook is not in place, which may easily cause damage to the interior of the notebook. The conventional molding process is adopted, such as image 3 As shown, the product is stamped from one side of the right-angled edge. Even if the area of ​​the circle increases, the corners are often damaged and cracked due to the extrusion between the metals, which affects the quality of the product.
