During the drawing process of the wire drawing machine, the surface of the drawn wire sometimes appears to be unqualified. In actual operation, we need to choose response measures according to the specific situation to reduce losses. There are several different phenomena for product surface failure. Here we will introduce two of the more common situations and introduce them separately below.
The first problem is that the surface of the wire drawn by the wire drawing machine equipment has scratches, bruises and scratches. There are seven main reasons, namely: there is a jumper problem on the cone; there is a groove mold on the cone; the wire rubs the edge of the take-up reel when taking up the wire; there is a certain part of the equipment that will cause damage to the wire; There are bruises between the disks; the ground is uneven and the take-up line is too full, etc.
In view of the causes of the problems analyzed above, we give the following suggestions: 1. Polish the surface of the cone wheel of the wire drawing machine equipment in time and correct the angle; 2. Remove the cone wheel for repair; 3. Adjust the wiring width and calibrate the cone wheel. Flat wire reel edge; 4. Timely maintenance and adjustment of this part; 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 excessive wire take-up. Full.
The second problem is that during the process of drawing wire using a wire drawing machine, problems such as pits, peeling, triangular openings, and burrs are found on the surface of the product. There are five main reasons for this problem, namely: the rod has flash, inclusions, shrinkage holes and other problems; 2. Poor pickling quality; 3. The hole is not smooth and has certain deformation; 4. Unreasonable lubrication ; 5. The cone wheel is not smooth, etc.
In response to this problem, the measures we should take are: firstly, we must strengthen the inspection of materials, and unqualified raw materials must not enter the wire drawing process; secondly, we must ensure the operating technology of the wire drawing machine equipment; thirdly, we must pay attention to maintaining the performance and quality of the molds used; Fourth, attention should be paid to lubrication and care; fifth, the surface of the cone wheel should be polished in time and the mold should be adjusted.
