Description

Technical Field

[0001] The utility model relates to the technical field of tower crane connecting piece production, in particular to a forging clamping tool for producing tower crane connecting pieces. Background Art

In construction, tower cranes are primarily used to hoist building materials, prefabricated components, and construction equipment. As large-scale machinery, tower cranes have numerous structures, each requiring connectors to connect them. These connectors vary depending on the component.

[0003] Tower cranes have numerous connecting parts. For example, taking metal shafts, which are common and required in large quantities on tower cranes, Chinese Patent Publication No. CN 213997668 U discloses a clamping device for metal forging, comprising a workbench with a movable ring movably mounted inside the workbench, a connecting ring fixedly mounted on the top of the movable ring, a first gear fixedly mounted on the top of the connecting ring, a fixed block fixedly mounted on the top of the first gear, hydraulic cylinders fixedly mounted on both the front and rear sides of the fixed block, a drive motor fixedly mounted on the top of the workbench, and a second gear fixedly mounted on the output shaft of the drive motor, which meshes with the gear.

[0004] The above-mentioned clamping device for metal forging utilizes two clamping plates to clamp the metal shaft. However, when forging the metal shaft, the heated metal shaft needs to be forged, hammered, and other operations.

The two clamping plates are in a suspended state under the action of the limit spring, causing the two clamping plates to shake greatly under the action of the impact force, thereby causing the metal shaft to shake greatly. The stability of the metal shaft cannot be guaranteed, and the forging work cannot be carried out normally. Utility Model Content
