Conical pipe stitch welding pressing device

Abstract

The invention belongs to the technical field of welding equipment, provides a conical pipe stitch welding pressing device, and aims to solve the problem that when a conical pipe is in stitch welding, a pressing action end cannot finely deflect when pressure is applied to a conical pipe by the pressing device. The pressing device comprises a side pressing mechanism and a hydraulic machine, the side pressing mechanism presses toward two sides of the conical pipe, the hydraulic machine presses toward the top of the conical pipe, the side pressing mechanism comprises a side pressing end and a side pressing cylinder connected with the side pressing end through a piston, the side pressing end comprises a carriage seat, an action end, a fixing shaft, a swinging rod and a fine tuning mechanism, the fixing shaft is fixed on the carriage seat, one end of the swinging rod is connected with the action end, the fine tuning mechanism comprises a pressure-bearing rod, a pressure-bearing sleeve and a gasket, the pressure-bearing rod is arranged on the carriage seat, one end of the pressure-bearing sleeve is a fine tuning end sleeving the pressure-bearing rod, the other end of the pressure-bearing sleeve is rotatably connected with the swinging rod relative to the other end connected with the action end, one end of the pressure-bearing rod is abutted to the fine tuning end through the gasket, and the other end of the pressure-bearing rod is provided with a fine tuning nut abutted to the fine tuning end through the gasket.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and relates to a conical pipe seam welding and pressing device. Background technique [0002] With the continuous construction of UHV power grids, more and more UHV steel pipe towers and substation frame supports are used in transmission lines, and due to their special structural forms, straight seam welded pipes in steel pipe towers and substation frames The amount of processing is very huge, and a considerable part of the straight seam welded pipe is tapered. Due to the internal welding characteristics of the seam welding machine, the opening of the seam of the steel pipe is at the 6 o'clock direction and parallel to the horizontal plane, so when the seam is welded When the in-seam welding machine performs seam welding on the tapered pipe, the axial position of the tapered pipe is constantly changing, so that the angle of the pressing end of the tapered pipe to be welded will occur al...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that when the conical steel pipe is seam welded, since the pressing device cannot make the pressing end slightly deflect during the process of applying pressure to the tapered pipe, the pressing end cannot adapt The problem of the slight angle change that occurs on the surface of the tapered pipe as the welding advances, and a conical pipe seam welding pressing device is provided to solve this problem
