A rolling stick is equipped in mounting groove.
Further, the material for rolling stick is hard tungsten alloy.
The beneficial effects of the utility model are: the utility model provides a kind of low friction bending mechanism, when the punch-pin
Mechanism is being applied pressure to downwards automatically when bending part, and the bending part to bending part offsets with the rolling stick, and the rolling
Dynamic stick rotates in the arc mounting groove, and rolling friction is changed into sliding friction, greatly reduces bending part fillet
Friction, the shaping groove in bending part surface and cavity plate molding die for bending part do not injure substantially, on the one hand prolong
The service life of mold has been grown, has on the other hand avoided and causes product surface occur to pull quality problems.
