Causes and solutions of wire breakage in wire drawing machine
In this production process, the quality of the wire drawing machine is checked layer by layer. But good quality wire drawing machine does not mean that the customer will not have problems during use, perhaps because of improper operation, or because of other external factors. For these problems, we basically found out the reasons for the broken wire of the drawing machine. Share with everyone.
The main reasons for wire breakage in wire drawing machine:
1. Due to the unstable annealing current during production, the sudden high current may easily cause the wire to be suddenly broken during the annealing process, or be melted directly by the suddenly increased current to cause wire breakage.
2. The material has quality problems. During the production process, if the metal rod material has quality problems, it will cause unpredictable changes in the tension of the wire during the deformation of the wire, and at the same time cause the wire to be broken;
3. The wire drawing die of the wire drawing machine will wear out after a long period of work and the sizing area of the wire drawing die will become larger, resulting in wire breakage.
In response to the wire breakage of the above wire drawing machine, we have proposed our own solution and give the following two suggestions to customers:
1. During the production process, it is necessary to constantly observe whether the annealing current of the wire drawing machine is normal, especially at the beginning of the start, you must pay special attention to the change of the annealing current. It is that the annealing current keeps increasing with the increase of line speed until it reaches the normal position, so as to ensure the normal operation of the entire wire drawing machine without wire breakage;.
2. Before the production, the quality of the metal wire must be tested, and the quality defects of the wire should be found in time, and then the wire drawing machine can be better adjusted for the quality of the wire. To a certain extent, it can avoid the phenomenon of wire breakage, or cut off the defective wire, thereby ensuring the smooth progress of the wire drawing machine during the I operation process;
3. Maintain the parts of the wire drawing machine frequently. If the parts are worn to a large extent, replace the parts in time to ensure the normal operation of the wire drawing machine.
