The effective maintenance and repair of drawing die is very important to reduce the cost.
Due to the vibration of the wire rod,the wire rod in the first contact area of the compression area of the Diamond Drawing Die first produces some slight annular wear,and then continues to expand until the sizing area,resulting in serious deterioration of the surface quality of the wire rod and expansion of the wire rod size.
Excessive wear will greatly reduce the number of mold maintenance,or even scrap,resulting in increased drawing costs.
How to improve the quality of wire drawing dies,which can be said to be the answer that many enterprises are asking,but so far no one has found the absolute answer,because many enterprises just run full power production,but ignore the problem of R & D.
First of all,we all know whether the quality of the drawing die is good or not,which has an extremely important relationship with the final quality of the product.Whether it is the output or quality of the product,or even the market competitiveness of the product,it is difficult to escape the impact of quality,which is one of the reasons why we must pay attention to it.
In addition,with the continuous change of the market,many manufacturers have put forward the requirements of high-end products of drawing dies.Once there are product requirements and demands,there must be reasonable people to solve the problem,which is the only way to improve the quality of drawing die.
Moreover,severe wear will lead to transverse cracks (mainly in the drawing process of soft wire) or longitudinal cracks (mainly in the drawing process of hard wire) in the die,which will lead to premature die scrapping.
Therefore,it is necessary to scientifically formulate the maintenance specification of drawing die according to the type and characteristics of drawing.
Generally speaking,slight ring wear can only be restored after polishing,or a little larger diameter can meet the requirements of Diamond Wire Drawing Dies.
Excessive wear will greatly reduce the number of mold maintenance,or even scrap,resulting in increased drawing costs. |
