Reasons for unqualified surface quality of wire drawing products
During the drawing process of the wire drawing machine, the surface of the drawn wire sometimes has the problem of unqualified. In practice, we need to choose countermeasures to deal with according to the specific situation to reduce losses. There are several different phenomena of unqualified product surface. Here we will introduce two of the more common situations, which will be introduced separately below.
The manifestation of this problem is that there are scratches, bumps and scratches on the surface of the wire drawn by the wire drawing machine. There are seven main reasons, which are: there is a jumper problem on the tower wheel; there is a groove mold on the tower wheel; the wire is rubbing the edge of the wire reel when the wire is retracted; there is a certain part of the equipment that will cause damage to the wire; There are bumps between the discs; the ground is uneven and the take-up is too full.
In view of the causes of the problems analyzed above, our suggestions are: 1. Trim the surface of the pulley of the wire drawing machine equipment in time and correct the angle; 2. Remove the pulley for repair; 3. Adjust the width of the cable and correct the angle. 4. Repair and adjust the part in time; 5. The wire reel should be placed in a "T" shape; 6. Renovate the floor; 7. Maintain a serious and responsible attitude during work to prevent over-reeling Full.
The performance of the second problem is that in the process of drawing the wire with the wire drawing machine, it is found that there are pits, peeling, triangles and burrs on the surface of the product. There are five main reasons for this problem, namely: the rods have flash, inclusions, shrinkage holes, etc.; 2. The pickling quality is poor; 3. The hole is not smooth and there is a certain deformation; 4. The lubrication is unreasonable 5. The tower wheel is not smooth and so on.
In response to this problem, the measures we should take are: first, strengthen the inspection of materials, and unqualified raw materials should not enter the wire drawing process; second, 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 lubricating care; fifth, the surface of the pulley should be polished in time and the mold matching should be adjusted.
