Lifting stand column transmission mechanism of H steel door welding machine

Abstract

The invention discloses an H steel door welding machine lifting stand column transmission mechanism, and particularly relates to the field of steel welding equipment.The H steel door welding machine lifting stand column transmission mechanism comprises a support and at least one transmission assembly, the transmission assembly comprises a driving component, a plurality of supporting components and a plurality of overturning components, and the driving component is used for driving the supporting components to move; the overturning part and the supporting part are arranged in a matched mode, the overturning part comprises an abutting rod, a pushing block and a first driving part for driving the pushing block to move, the abutting rod is connected with the support, and the pushing block is connected with the abutting rod in a sliding mode. According to the lifting stand column transmission mechanism of the H steel door welding machine, steel is conveniently driven to move through the overturning component, then the steel is overturned, further welding of the steel is facilitated, and the welding efficiency of the steel is improved.

Description

technical field [0001] The invention relates to the field of steel welding equipment, in particular to a transmission mechanism for a lifting column of an H steel door welding machine. Background technique [0002] H-shaped steel is an economical cross-section high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. Because all parts of H-shaped steel are arranged at right angles, H-shaped steel has strong bending resistance in all directions and simple construction. , cost saving and light structure weight, etc. H-beams can be produced by welding or rolling, and H-beams are usually welded by portal welding machines. [0003] In the related art, when welding H-beams, the steel strips with appropriate thickness are first cut into appropriate widths, then the cut steel plates are spliced, and then the steel plates are welded by a portal welding machine to complete the welding of the H-beams. [0004] In view o...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that the H-shaped steel needs to be welded on both sides. Usually, when one side is welded, the H-shaped steel needs to be transported out of the welding machine, then turned over, and then transported back to the welding machine for welding, which wastes time and leads to Reduced welding efficiency
