The wire drawing die is a die used to make the metal wire gradually reach the size people need from thick to thin. In metal pressure processing, the metal is forced to pass through the die under the action of external force. The wire drawing die has a wide range of uses, such as electronic devices and radar. High-precision wires used in, TV, instrumentation and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires can be drawn with a wire drawing die.
To
During the long-term use of the wire drawing die, the die wall is subject to strong friction and scouring of the metal wire, which will inevitably produce abrasion. The most common one is the annular groove (dent) at the wire entrance in the working area. The appearance of the ring groove of the drawing die has aggravated the wear of the die hole, because the small particles of the core material that peeled off due to the loosening of the ring groove are brought into the working area and the sizing area of the die hole by the metal wire, acting as an abrasive, and entering The wire of the die hole aggravates the wear of the die hole like a grinding pin. If it is not replaced in time for repair, the ring groove will continue to expand rapidly, making repair more difficult, and there may even be cracks in the deeper part of the ring groove, causing the mold to be completely broken and scrapped.
To
Therefore, it is necessary to scientifically formulate the maintenance specifications of the wire drawing die according to the type of material to be drawn and the characteristics of the wire drawing machine. Under normal circumstances, slight ring wear needs to be polished to resume use, or a slight enlargement of the diameter can also meet the wire drawing requirements. Excessive wear will greatly reduce the number of mold repairs, or even scrap. Regular maintenance can extend the life of your drawing molds and reduce production costs.
