Wire Drawing Products Unqualified Surface Quality Reasons

During the drawing process of the wire drawing machine, the surface of the wire drawing products sometimes has unqualified problems. In actual operation, we need to choose countermeasures according to the specific situation to reduce losses.

Unqualified product surface includes several different phenomena. Here we will introduce two of the more common situations, and they will be introduced separately below.

The first problem is that there are scratches, bruises, and scratches on the surface of the wire drawn by the wire drawing machine equipment.

It mainly includes seven reasons, namely: there is a jumper problem on the tower wheel; there is a groove mold on the tower wheel; There are bruises between the discs; the ground is uneven and the winding line is too full.

In view of the causes of the problems analyzed above, the suggestions we give are as follows:

1. Repair the surface of the tower pulley of the wire drawing machine equipment in time, and correct the angle;
2. Remove the tower wheel for repair;
3. Adjust the width of the line and level the edge of the line;
4. Overhaul and adjust this part in time;
5. The reel should be placed in a “T” shape;
6. Renovate the floor;
7. Maintain a serious and responsible attitude during work to prevent overfilling.

The second type of problem is that in the process of drawing wires with wire drawing machine equipment, it is found that pits, peeling, triangles, and burrs appear on the surface of the product.

There are five main reasons for this problem, namely:

1. The rod has problems such as flash, inclusion, shrinkage cavity, etc.;
2. Poor pickling quality;
3. The hole is not smooth and has certain deformation;
4. Unreasonable lubrication;
5. The tower wheel is not smooth, etc.

To address this issue, the measures we should take are:

The first is to strengthen the inspection of materials, and unqualified raw materials are not allowed to enter the drawing process;

Secondly, it is necessary to ensure the operation process of the wire drawing machine equipment;

Third, pay attention to the performance and quality of the molds used;

Fourth, attention should be paid to lubrication care;

Fifth, the surface of the tower wheel should be polished in time, and the mold matching should be adjusted.
