S-shaped steel positioning and shaping device

Abstract

The invention relates to an S-shaped steel positioning and shaping device. The S-shaped steel positioning and shaping device comprises a workbench and oil cylinders, wherein a lower cross beam is arranged at the lower end of the workbench, the oil cylinders comprise positioning oil cylinders, clamping oil cylinders, pressing oil cylinders and shaping oil cylinders, the positioning oil cylinders are sequentially and fixedly arranged on one side of the top of the lower cross beam, the clamping oil cylinders are fixed to the other side of the top of the lower cross beam in parallel, the positioning oil cylinders, the clamping oil cylinders, the pressing oil cylinders and the shaping oil cylinders are installed at equal intervals, clamping molds, positioning molds, S-shaped steel and a transverse plate are placed on the workbench, the positioning oil cylinders are connected with the positioning molds, the clamping oil cylinders are connected with the clamping molds, the positioning molds and the clamping molds fix the S-shaped steel and the transverse plate from the two sides, the pressing oil cylinders press the top of the S-shaped steel and press the S-shaped steel and the transverseplate on the top of the lower cross beam, and the shaping oil cylinders are located at the bottom of the transverse plate. The S-shaped steel positioning and shaping device is simple in structure, convenient to use, accurate in positioning, high in welding precision, good in consistency, small in welding deformation and convenient to shape, the efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a shaped steel fixing device, in particular to an S-shaped steel positioning and shaping device. Background technique [0002] Bridge expansion joints refer to expansion joints usually set between two girder ends, between girder ends and abutments, or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. It is required that the expansion joints can freely expand and contract in two directions parallel to and perpendicular to the bridge axis, and are firm and reliable. The vehicles should run smoothly without sudden jumps and noises; they should be able to prevent rainwater and garbage from infiltrating and blocking; installation, inspection, and maintenance , Elimination of dirt should be simple and convenient. Where expansion joints are set, railings and bridge deck pavement must be disconnected. The function of bridge expansion joints is to adjust the displacement and connect...

AI Technical Summary

Problems solved by technology

The bent S-shaped steel will have elastic deformation, which will bring difficulties to welding positioning

In the prior art, there is a lack of special equipment for welding the S-shaped steel and the horizontal plate together. It can only be manually marked and then fixed with a clamp. Not only the production efficiency is low, but also the welding accuracy is low, the consistency is poor, and the welding deformation is large. Difficulty in follow-up shaping and high processing cost
