In order to ensure high-quality wire and effectively control the cost of mold use, attention should be paid to the following aspects:

To ensure the smooth operation of the wire drawing die equipment; each wire drawing drum and wire guide roller should be smooth and flexible, and their runout tolerances should be strictly controlled. If it is found that the drum and guide wheel have worn grooves, they should be repaired in time.

Good lubrication conditions are important conditions to ensure the surface quality of the wire and extend the life of the mold. Always check the lubricating strength index, 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, the lubrication system must be replaced and cleaned in time.

Reasonable mold matching is the key element to ensure the surface quality of the wire, control the size accurately and consistently, reduce the wear of the wire drum and reduce the operating load of the equipment. For the sliding wire drawing machine, it is necessary to be familiar with the mechanical elongation of the equipment, and choose the sliding coefficient reasonably, which is the first step of mold matching.

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