What material is used for the tooth rubbing die that will not wear?

Core hardening (1.2344 1.2767, etc. ), and the braces are screwed with a wear-resistant (copper cup) mold? Knocking is knocking. Any material can be tapped as long as it is not quenched, but low carbon steel is more suitable for tapping. The utility model discloses a tooth rubbing mechanism for a tooth rubbing mold, which comprises a motor, a sprocket A, a sprocket B, a chain and teeth, wherein the motor is connected with a motor fixing block, the sprocket A is installed on the tooth rubbing, and the sprocket A and the sprocket B are connected through chain transmission; A tooth rubbing sleeve is sleeved below the sprocket B, and an outer ball sleeve is also arranged on the tooth rubbing. The utility model has reasonable structure. The tooth sleeve and the outer ball sleeve are added to the teeth, which can ensure that the teeth will not be worn and will not swing because of the wear of the teeth, so that the products will not flash, and the water channel is added to dissipate heat for the tooth mechanism, which ensures the mobility of the tooth mechanism and prolongs the service life.
