Punching device for steel corrugated pipe production
By designing clamping components and tension spring devices, the corrugated steel pipe is straightened to an approximately straight state, solving the problem that traditional punching equipment cannot conform to curved surface contours, thus achieving accurate and uniform punching of the corrugated steel pipe and avoiding hole collapse.

Abstract
The utility model relates to a punching device for steel corrugated pipe production relates to steel corrugated pipe processing field, including bottom plate, fixedly arranged in the vertical board of bottom plate top surface one side, set up in the lateral wall of vertical board horizontal plate, fixedly set up in the air cylinder of horizontal plate, fixedly set up in the electric drill of air cylinder bottom, fixedly set up in the fixed plate of bottom plate top surface, slidingly set up in the sliding plate of bottom plate top surface and set up in the butt joint plate of bottom plate top surface and be located between fixed plate and sliding plate. In the utility model, the clamping assembly can clamp the both ends of the steel corrugated pipe, the tension spring drives the sliding plate and the fixed plate to exert the axial tension on the both ends of the steel corrugated pipe, straightens the curved surface profile of the steel corrugated pipe to the approximate straight line state, makes the pipe body lateral wall and electric drill bit vertical adhesion, eliminates the punching deviation caused by the pipe body curved surface.
