Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, specifically a punching machine with a straightening function. Background Technology

[0002] In the field of construction scaffolding, cup-lock scaffolding and ring-lock scaffolding are two common types. They are used to build temporary support structures. Cup-lock scaffolding uses a cup-lock design for its joints, while ring-lock scaffolding uses a ring-plate connection.

[0003] Deformation may occur when dismantling the scaffolding's rim and ring fasteners. In such cases, a punching machine with a straightening function is needed. The straightening mechanism can straighten the bent parts of the scaffolding, restore the straightness of the steel pipes, and avoid stability problems caused by bending during overlapping. The punching mechanism can also punch and correct the misalignment of scaffolding pipes, thereby enhancing the bending resistance of the steel pipes or correcting misalignment of connectors caused by deformation.

[0004] However, existing punching machines with straightening functions have limited applicability when straightening cup-lock and ring-lock scaffolding due to the different pipe diameters and the limited variety of limit block specifications. Furthermore, different tools are required for punching and straightening pipes, and traditional tool replacement methods using threaded connections result in excessive disassembly time, affecting straightening efficiency. Therefore, those skilled in the art have provided a punching machine with straightening function to solve the problems mentioned in the background. Utility Model Content
