Description
Technical Field
[0001] This utility model relates to the field of cold heading machine manufacturing technology, and in particular to a mechanism for longitudinally rotating a clamp by 90 degrees. Background Technology
[0002] A cold heading machine is a device that cuts and cold-extrudes various processed metal wires, forming them into shapes within a mold. It is used to process various standard or non-standard fasteners. The clamping mechanism is the workpiece transfer mechanism within the cold heading machine's clamping system. When a workpiece is transferred from one station to the next, the clamps can open and close and rotate 180°, accurately transferring the workpiece from one station to the next, completing the workpiece reversal process. To process the side of the workpiece, the clamps need to be able to rotate the workpiece 90 degrees.
[0003] For example, Chinese Patent Publication (Announcement) No.: CN104190843A, patent title: Cold Heading Machine Clamp Piece Outward Flipping Mechanism, it discloses the technical solution of "
[0004] The present invention is implemented by the following technical solution: Cold Heading Machine Clamp Piece Outward Flipping Mechanism, including multiple feeding clamps that move back and forth in front of the cold heading machine bottom mold base, the lower end of the clamps are left and right jaws that can open or close, characterized in that: at least one clamp... when the flipping cam flips outward, it drives the clamp piece to flip outward" and achieves the technical effect of "
[0003] In view of the shortcomings of the background technology, the purpose of the present invention is to provide a cold heading machine clamp piece outward flipping mechanism that can realize the workpiece flipping outward by 90 degrees in the cold heading process, so that the workpiece can be upset in two mutually perpendicular directions, thereby greatly expanding the application space of the cold heading machine".
[0004] When processing two mutually perpendicular surfaces, it needs to move from the cold heading station M to the cold heading station N. That is, it cannot perform the heading process on two mutually perpendicular surfaces at the same station, resulting in low work efficiency. Therefore, it needs to be improved.
[0005] For example, Chinese Patent Publication (Announcement) No.: CN107931506B, patent title: A clamping device for a cold heading machine, which solves the technical problem that "some clamps in the prior art can rotate the workpiece by 90 degrees, but these clamps have complex structures and are inconvenient to operate".
