[CN 201820129645.9] A Multi-station Cold Heading Machine Running Clamp Mechanism
[CN 201820129645.9] Title of a multi-station cold heading machine running clamp mechanism: Application number of a multi-station cold heading machine running clamp mechanism: CN 201820129645.9 Applicant: Jinhua Guoding Hardware Products Co., Ltd. Application Date: 2018-1-28 Patent Type: Utility Model The utility model relates to a cold heading machine structure, especially to a multi-station cold heading machine running clamp mechanism, which solves the problem of inconvenient use of running clamps, including clamping shafts and clamps, as well as movable blocks, the movable block is movably connected with the sandwich shaft, and the movable block rotates with the connection point with the sandwich shaft as the rotation center. There are two movable blocks, and the movable blocks are symmetrically arranged on both sides of the sandwich shaft. A spring is arranged between the same end of the movable block, and the clamp is arranged at the other end of the movable block. The clamp and the movable block are fixedly assembled, and the movable block is connected with the sandwich shaft through a fixed pin, the clamp and the movable block are connected by screws to meet the needs of the cold heading process with large deformation. The compression spring is placed back. On the one hand, the length of the spring is increased to the greatest extent, thereby increasing the compression stroke of the spring. On the other hand, the lever principle is used to improve the clamping force of the clamp, making the clamp more stable, and the structure is simple, convenient for production and processing, and reducing economic costs.
