Shearing means of a differential temperature compensation multi-curvature bending equipment and technology

The present invention discloses a multi-curvature bending shear temperature difference compensating apparatus comprising a stationary die, a movable die, positioned box, made up by the stationary die mold, a stationary mold, alternatively gap sleeve, and the fuse material conveyor configuration; fully movable die by a replaceable sleeve, the movable die, the movable die, a large torque nuts, screws, and the right gripper composition; material is composed of a conveyor and a left hydraulic gripper rod; on the stationary mold, made up mold box positioning means, the upper mold located above the fixed mold and make up tank positioned immediately to the left; alternatively gap sleeve fitted to the stationary and fixed mold and the upper mold between the mold and made up, make up for interference mold mating; fuse is a fuse by the movable coil, winding and unloading fixing the fuse wire, and the elements at both ends of the pin ends of the fuse's temperature controller were blended. The process comprises two steps. The present invention can be effectively used to improve the processing of the pipe wall wrinkling and cracking phenomenon, so the pipe after processing more durable.
