Technical Field

[0001] The utility model relates to the technical field of arc steel plate punching, in particular to a punching device for arc steel structures. Background Art

[0002] Steel structures are mainly made of molten steel poured and pressed after cooling. There are a wide range of steel structure types, including many curved plates with a certain curvature, which are used in metal roofs in public buildings. They get rid of the traditional horizontal shape and present curved arc-shaped steel plate metal roofs. Before installation and use, most of these curved steel plates need to be punched with a punching machine to insert screws for laying and installation;

[0003] The existing punching machine for punching holes in arc-shaped steel plates generally fixes and stabilizes the arc-shaped steel plate to be punched by a fixing fixture, and then punches the fixed arc-shaped steel plate.

[0004] When the above-mentioned existing punching machines are performing punching operations, their fixing fixtures can mostly only be used to fix curved steel plates of one size and thickness. When faced with curved steel structure plates of different sizes and thicknesses, the used fixing fixtures need to be disassembled and then matched fixing fixtures need to be installed, which is rather troublesome and inconvenient.

[0005] Based on this, the utility model designs a punching device for arc-shaped steel structure to solve the above problems. Summary of the invention

[0012] Preferably, a motor is fixedly connected to the outer wall of the mounting seat, and a drill bit is drivingly connected to one end of the motor shaft.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the storage seat can be used for placing curved steel plates with more curvatures, the spacing between the two clamping plates can be adjusted, and it is suitable for clamping curved steel plates with wider widths. At the same time, the first hand-tightening bolt of the horizontal plate can be screwed to further clamp and stabilize the curved steel plate in cooperation with the storage seat. The adjustable first hand-tightening bolt can be used for curved steel plates with more thicknesses, and then the curved steel plates with more sizes and thicknesses can be punched stably, without frequent and troublesome disassembly and assembly, which is more convenient.
