Multi-wing-plate H-shaped steel door type straightening machine

Abstract

The invention discloses a multi-wing-plate H-shaped steel door type straightening machine which comprises a guide device. A straightening main machine is arranged on the right side of the guide device, the guide device comprises a base, servo drivers are arranged at the two ends of the base correspondingly, and lead screw transmissions are fixedly connected to the opposite faces of the servo drivers correspondingly. Sliding rail guides are fixedly connected to the two sides of the top of the base, wing plate depended wheels are arranged in an inner cavity of a door-shaped frame, web dragging wheels are arranged on the opposite sides of the door-shaped frame, the straightening main machine comprises a main machine frame and a lifting mechanism, and a fixed steel plate is fixedly connected to the top of the main machine frame. The opposite faces of the fixed steel plate are fixedly connected with synchronous shafts, the top of the fixed steel plate is provided with a lifter, the bottom of the lifter is fixedly connected with a lifting beam, the bottom of the lifting beam is fixedly connected with a lifting guide column, and the middle of the bottom of the lifting beam is movably connected with an upper correcting unit. A lower correcting unit is arranged at the bottom of the inner cavity of the main machine frame.

Description

technical field [0001] The invention relates to the technical field of H-shaped steel straightening, in particular to a multi-blade H-shaped steel portal straightening machine. Background technique [0002] Conventional H-shaped steel is welded by two flange plates and one web plate. Due to the principle of thermal expansion and contraction of the weld seam, the angle of the flange plate relative to the web plate is deformed, so correction equipment is required to correct the component. However, with the development of various industries, in order to obtain components with higher unidirectional strength and smaller width, a multi-flank H-shaped steel component has emerged, and its application fields include steel structures such as ships and integrated buildings. The H-shaped steel with multiple wings is welded by three or more wings and one web. [0003] The existing correction equipment needs to correct the flanges not only on the outermost two sides, the traditional H-sh...

Problems solved by technology

[0003] The existing correction equipment needs to correct the flanges not only on the outermost two sides, the traditional H-shaped steel correction equipment cannot realize the flange plate correction of this multi-flange H-shaped steel member, on the other hand, the traditional shipbuilding industry The rib plate straightening machine cannot straighten the thicker flange plate
