　　In order to ensure high-quality wire and effectively control the cost of mold use, the following points should be paid attention to when using wire drawing molds

　　1. To ensure the smooth operation of the wire drawing equipment: the wire drawing drums and wire guide wheels should be smooth and flexible, and their runout tolerances should be strictly controlled.

　　If the drum wheel or the guide wheel has worn grooves, it should be repaired in time.

　　2. A good lubrication condition is an important condition to ensure the surface quality of the wire and extend the life of the mold. It is necessary to check the lubrication index frequently, remove the copper powder and impurities in the lubricating oil, so that it does not pollute the equipment and die holes. If the lubrication fails, it must be timely Replace and clean the lubrication system.

　　3. Reasonable matching of molds ensures the surface quality of the wire, the control size is accurate and consistent, reduces the wear of the drawing drum, and reduces the key factor of the equipment operating load. For the sliding wire drawing machine, it is necessary to be familiar with the mechanical elongation of the equipment, and to select the sliding coefficient reasonably, which is the first step of die matching.

　　4. Select the die pass according to the material of the wire to be drawn and the reduction rate of each drawing. Generally speaking, the harder the drawn wire, the smaller the compression angle of the die and the longer the sizing area; vice versa. The reduction rate of each drawing is also closely related to the compression angle of the corresponding die, and the compression angle should be adjusted appropriately according to the reduction rate.
