In fact, in almost all metal manufacturing industries, there are requirements of one kind or another for the surface requirements, and some are very strict to the point of being outrageous. In the production of a small screw, its surface is also in compliance with such requirements and regulations. In production, we must respond quickly to possible problems, find and solve them in time, only in this way, we can grasp the production process in production and make a good check on the quality of our products. General surface defects will have such and other problems in these two links. The first is the beginning of this link. There are many bad phenomena, so we should reflect on how to avoid such bad phenomena and what caused our mistakes.
Phenomenon one is eccentricity. This error is usually caused by a problem in the installation of the second punch or an error in the mechanical adjustment; phenomenon two, the head is tilted, this problem is the most troublesome for us, the first punch is installed incorrectly and the adjustment is unfavorable; Third, if the head is not round, it must be a problem with our punching tools; phenomenon four, cracks, double layers, that is, the molding is our work is not in place; phenomenon five, there are burrs, except for the problems during molding It is also possible that the crevices of the punching tool have not been well grasped; Phenomenon 6, the head has cracked, which shows that we made a mistake in the selection of materials.
The second link is the process of tooth formation. Phenomenon one, there are cracks in the processing, in addition to the adjustment problem, there is also the problem of the tooth plate; second, the fire, the distance is too large, and the time is not well grasped; third, crooked If the tail is docked, the debugging machine is too tight or too loose, this operation is problematic; fourthly, if the rod is crooked or the tooth bottom is rough, it is worth checking whether it is the correction problem or the tooth distance Not well adjusted.
In fact, during the production process, we will always have this and that kind of problems, but think about the problems that we have, and come to our conclusions, and then we will sum up and avoid such risks. For a good screw It is very important for production.
