Notices for surface treatment of automobile sheet metal parts.
First: It should be noted that the state of the workpiece, all electrochemical treatment must be carried out in the bulk of the workpiece, the assembly feel that it can not be electrochemical treatment. Because in the process of treatment, the solution will be trapped in the gap of the assembly and cause corrosion to the workpiece.
The application of automobile stamping parts processing technology is more and more extensive. Many parts, including tools, are stamped by machines. Like automobile lampshade, we all know that the shape of lampshade is elliptical, and the parts of this shape are not easy to produce. Using stamping technology, they can be realized very well.
Automobile stamping parts are obtained under the action of stamping force, so there will be certain deformation, size, shape and other aspects of the corresponding deformation. For stamping parts, sheet metal, die and equipment are the three indispensable elements in the forming process, which play a vital role in the forming quality of stamping parts.
The testing methods for stamping parts of automotive parts are as follows:
Touch test: wipe the surface of the outer covering with clean gauze. Inspectors need to wear touch gloves to touch along the stamping part vertically close to the surface of the stamping part. This inspection method depends on the experience of the inspectors. If necessary, the suspicious area can be polished and verified by oil stone, but this method is an effective and rapid inspection method.
