In the work of wire drawing machine equipment, its mold is a very important part. As users, we need to pay more attention to its use and carry out appropriate maintenance. In fact, we often encounter three problems in the daily use of wire drawing machine equipment and molds. These three problems are what we must pay attention to. Let's take a look at the specific content together.
One issue that should be paid attention to is whether the choice of working cone angle is reasonable. If the angle we choose is unreasonable, when the wire drawing machine is drawing the wire, whether the working cone angle is too large or too small, it will bring certain negative effects. If the tensile stress is too large, the problem of axial extension is likely to occur in the sizing area, resulting in a series of problems such as diameter reduction, ellipse, and poor lubrication, which will eventually affect the production effect of the equipment.
The second issue that needs attention is whether the center is broken or is a herringbone crack. For this problem, many people think that it is caused by the problem of the mold material. It was only then discovered that the root cause of this problem was improper drawing process arrangement. In the drawing process of wire drawing machine equipment, if the tensile stress used exceeds the strength it can withstand, then it will lead to the appearance of cracks.
The third issue that needs attention is its residual stress and surface work hardening. In fact, this situation is mainly caused by residual work. Under the effect of residual work, the problem of material hardening will be more serious, and if the situation is serious, it may even cause the surface of the wire to crack and peel. Therefore, if the process is not properly selected, it will eventually lead to a decline in the work quality of the wire drawing machine.
Therefore, for users and friends, we must pay more attention to these three aspects in the production process, and avoid these problems as much as possible, so as to ensure the working quality of the wire drawing machine.
