The effective maintenance and repair of wire drawing die is very important to reduce the cost. The first contact of the wire in the compressed area of the drawing die due to the vibration of the wire.
At first, some slight annular wear occurs in the area, and then it continues to expand until the sizing area, resulting in serious deterioration of wire surface quality and wire rod size
Inch expansion.
Excessive wear will greatly reduce the number of die maintenance, and even scrap, resulting in the increase of wire drawing cost. Effective maintenance and repair of wire drawing die for reducing
Cost is very important. Due to the vibration of the wire, some slight annular grinding is first produced in the first contact area of the wire rod in the compression area of the drawing die
The surface quality of the wire rod deteriorates seriously and the wire size expands.
How to improve the quality of the drawing die, which can be said to be the answer of many enterprises, but so far no one has found the absolute
The answer is that many enterprises just drive full power production, but ignore the problem of research and development.
First of all, we all know that the quality of the drawing die is good, which is closely related to the final quality of the product
The important connection, whether it is the output or quality of products, or even the market competitiveness of products, is difficult to escape the impact of quality
Is one of the reasons why we must pay attention to it.
In addition, with the continuous change of the market, many manufacturers also put forward the requirements for high-end products of drawing dies
Demand, there must be a reasonable person to solve the problem, this is the only way to improve the quality of the drawing die.
In addition, severe wear can lead to transverse cracks (mainly in the drawing process of soft wire) or longitudinal cracks (mainly
In the process of hard metal wire drawing), resulting in premature die scrapping. Therefore, it is necessary to carry out scientific research according to the types and characteristics of wire drawing
Drawing die maintenance specification. Generally speaking, slight annular wear can only be restored after polishing, or the diameter is slightly larger
It can meet the requirements of wire drawing. Excessive wear will greatly reduce the number of die maintenance, and even scrap, resulting in the increase of wire drawing cost. |
