Description

Technical Field

[0002] In metal forming technology, roll forging is more common, especially in the production of long shaft forgings to achieve volume distribution and pre-forming, reduce the final forming load, form a precision roll forging composite production line, with less investment in large quantities to produce complex forgings, such as automobile front axles, connecting rods, injector forgings.

[0003] In the roll forging production line of long-axis forgings, it is common that after roll forging by the roll forging machine, its clamp will throw out the roll forging; after conventional roll forging, the two ends of the workpiece are of different sizes. The smaller end is the roll forging elongated end, which has an inclination after deformation, an uneven end surface, and axial length error, which is not convenient for automatic positioning and clamping; the larger end is the clamping part of the clamp during the roll forging process, and the clamping part of the roll forging machine clamp has no roll forging deformation, which is convenient for the automatic clamping mechanism to position and clamp, but because the large end is occupied by the roll forging machine clamp, the forging needs to be thrown out after the roll forging is completed, and the small end faces the conveying direction of the forging. With the popularization of automated forging production lines such as robots, it is necessary to position the forgings at the end of the conveying line after roll forging, and the large end needs to face the conveying direction of the forgings in the subsequent forging process for automated clamping. In the past, it was transported manually. With the popularization of robot automated production lines, stable and controllable axial reversing devices have a large number of application needs in the field of roll forging.
