7x7 Pvc Coated Wire Rope Cutting Process

7x7 pvc coated wire rope cutting process, divided into artificial wire cutting, line cutting gap processing is not correct, no effect of clearing and line cutting metamorphic layer, 7x7 pvc coated wire rope die cutting edge mostly using wire cutting processing. Due to the thermal effect and electrolysis of the 7x7 pvc coated wire rope cutting process, the surface of the 7x7 pvc coated wire rope mold has a certain thickness of the metamorphic layer, resulting in a decrease in surface hardness, microcracking, etc.The wire rope die is prone to early wear, which directly affects the 7x7 pvc coated wire rope die blanking clearance and the edge is easy to chip, shortening the service life of 7x7 pvc coated wire rope. Therefore, in the 7x7 pvc coated wire rope cutting process should choose a reasonable electrical standard, to minimize the depth of the metamorphic layer.

Punching equipment selection: punching tonnage, punching force is not enough, the mold is too deep. The accuracy and rigidity of the stamping equipment is extremely important for the life of the 7x7 pvc coated wire rope die. The stamping equipment has high precision and good rigidity, and the life of the 7x7 pvc coated wire rope die is greatly improved. For use on ordinary open presses, the die must select a press with high precision and rigidity. Otherwise, the die life will be reduced, and in severe cases, the chess piece will be damaged.
