The 10 common ways of sheet metal bending are as follows:
(1) Bending from the inside to the outside;
(2) Bending from small to large;
(3) Bending special shapes first, and then bending - general shapes;
(4) Forming of the previous process does not have an impact on the succeeding process or interference.
The principle is to maximize the convenience of the next process. That is: easier to control the accuracy of the product, better rely on the fence, more simple to use the mold. It makes the molding of the product free from obstacles.
Expanded Information:
Sheet metal has the characteristics of lightweight, high strength, electrical conductivity (which can be used for electromagnetic shielding), low cost, mass production performance and so on. characteristics, in the electronic and electrical appliances, communications, automotive industry, medical equipment and other fields have been widely used.
For example, sheet metal is an essential component in computer cases, cell phones and MP3s. With the increasing application of sheet metal, the design of sheet metal parts has become an important part of the product development process, mechanical engineers must master the design of sheet metal parts skills, so that the design of the sheet metal not only to meet the functionality and appearance of the product and other requirements, but also to make the stamping die manufacturing simple, low-cost.
