Description

Technical Field

[0001] The present application relates to the technical field of metal forging, and in particular to a forging clamping device. Background Art

[0002] Forgings refer to metal parts that are processed by forging. Forging is a process that heats metal materials to a certain temperature and then plastically deforms them under forging presses or hammers. Forging can eliminate internal structural defects in metals, refine grains, improve the mechanical properties of metals, and obtain parts with fibrous structures. Therefore, forgings usually have good comprehensive mechanical properties and can withstand large loads and complex working environments.

[0003] Before forging, the rough blank needs to be pretreated, and after the pretreatment, the rough blank needs to be transferred to the forging table. The prior art discloses a clamping device for forging production, including a fixed main board, two connecting support plates are evenly installed in the middle of the fixed main board, and movable connecting plates are installed at both ends of the two connecting support plates. Two shrinkage grooves are evenly arranged inside the movable connecting plate, an electric push rod is installed between the movable connecting plate and the fixed main board, a hydraulic cylinder is installed below the movable connecting plate, a connecting block is installed at one end of the hydraulic cylinder, telescopic screws are installed at both ends of the connecting block, and a movable forging clamp is installed at the other end of the telescopic screw.

[0004] With regard to the above-mentioned related technologies, during the process of transferring the position of the rough blank, the connecting block is driven to rise and fall by the hydraulic cylinder, and the connecting block drives the movable forging clamp to move to the side of the rough blank through the telescopic screw, and then the movable forging clamp is driven by the telescopic screw to clamp and fix it to the side wall of the forging. When the mass of the forging is large, a larger clamping force is required to clamp the forging, and the larger clamping force will cause the movable forging clamp to damage the surface of the forging, and the clamping stability is also relatively poor.
