Causes of unqualified surface quality of wire drawing machine

Sometimes, there are sometimes unqualified problems in the drawing process of wire drawing machines. In practice, we need to choose the appropriate measures according to the specific circumstances to deal with, in order to reduce losses. Surface nonconformities include several different phenomena. Here we will introduce two of the more common cases, which are described below.

The first problem is that the surface of wire drawn by wire drawing machine equipment has some problems, such as scratches, bruises and scratches. The main reasons include: jumper problem on the tower wheel; groove mold on the tower wheel; wiring scrape the coil edge of the coil when drawing up and arranging the line; damage to the wire at some part of the equipment; bruising between the coil; uneven ground and over-full coil.

In view of the above analysis of the causes of the problem, we give the following suggestions: 1, timely wire drawing machine tower wheel surface trimming and angle correction; 2, remove the tower wheel for repair; 3, adjust the widths of line arrangement, leveling the edge of the wire disc; 4, timely maintenance and adjustment of this part; 5, wire disc should be placed in the "T" shape; 6, repair and repair; 6, repair the tower wheel. Floors; 7, we should maintain a conscientious and responsible attitude in our work to prevent overtaking.

The second problem is the use of wire drawing machine equipment in the process of drawing wires, found in the surface of the product pits, peeling, triangles and burrs and other issues. There are five main reasons for this problem, which are: the rod has flange, inclusions, shrinkage and other problems; 2, poor pickling quality; 3, the hole is not smooth, there is a certain deformation; 4, unreasonable lubrication; 5, tower wheel is not smooth and so on.

In view of this problem, we should take measures as follows: first, to strengthen the material testing, unqualified raw materials can not enter the drawing process; secondly, to ensure the operation process of wire drawing machine equipment; third, to pay attention to the performance and quality of the mold used; fourth, to pay attention to do a good job of lubrication care; fifth, should be timely polishing. Adjust the mould on the surface of the cone wheel.
