Small friction welder for frame foundation construction

Abstract

The invention relates to the technical field of friction welders, in particular to a small friction welder for frame foundation construction. The small friction welder comprises a base. A protection cover is arranged on the outer wall of the base. An electric hydraulic cylinder is arranged in the protection cover. A shaft body of the electric hydraulic cylinder penetrates through the outer wall ofthe base. One end of the shaft body of the electric hydraulic cylinder is connected with a first clamping plate. The first clamping plate clamps a bottom connected workpiece. A hole, for the shaft body of the electric hydraulic cylinder to penetrate through, of the base is internally provided with a silica gel heat conduction sleeve. A heat conduction rod is arranged on the outer wall of the silica gel heat conduction sleeve. The small friction welder has the advantages that the size is small, two workpieces are clamped by two clamping plates correspondingly, a rotating mechanism is added into a top base to drive one workpiece to rotate at a high speed so that friction welding can be realized, the small friction welder is more suitable for the building construction field, and the application range of the friction welder is enlarged.

Description

technical field [0001] The invention relates to the technical field of friction welding machines, in particular to a small friction welding machine for frame foundation construction. Background technique [0002] Friction welding is a method of using the heat generated by the friction between the end faces of the workpiece to make it reach a plastic state, and then upsetting to complete the welding. Because chips are often firmly stuck to the cutter head when turning workpieces, and local welding will also occur when the lubrication between the shaft and the bearing bush is poor, friction welding is invented based on these phenomena. Friction welding can be divided into continuous drive friction welding and inertia friction welding; [0003] The frame structure is a structure composed of many beams and columns to bear all the loads of the house. For high-rise civil buildings and multi-storey industrial plants, the load-bearing of brick walls can no longer meet the requirem...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the traditional friction welding machine has a large volume and is mostly used in the processing of workpieces in the mechanical lathe workshop. When the frame foundation construction is carried out on the construction site, the welding between the rod workpieces will also be encountered. Friction welding has obvious advantages for the welding of rods. advantages, but there is a lack of small friction welding machines for building construction on the market
