Tubular cutter for tube opening

Abstract

The invention relates to a device for processing steel structural members, in particular to a tubular cutter for tube opening, which comprises a welding machine, a base and a support rod connected with the base, and is characterized in that a cantilever is connected with the support rod through a sleeve, a hanging shaft and a motor seat are arranged on the cantilever, the lower end of the hanging shaft is provided with a die body fixedly connected with the hanging shaft, the upper end of the die body is provided with a cutting track, the hanging shaft at the upper end of the die body is sleeved with a rotary body, the lower end of the rotary body is in contradiction with the cutting track on the die body, a rotary gear and a connecting rod are arranged on the rotary body, the rotary gear is meshed with the motor output shaft gear fixed on a motor seat, the upper end of a suspender is connected with the connecting rod, the lower end of the suspender is provided with a welding gun connected with the welding machine, the tubular cutter for tube opening has the advantages of simplicity in operation, high processing efficiency, good processing quality, low production cost, low labor intensity of workers and the like, and is particularly suitable for forming round holes in a steel plate barrel body.

Description

technical field [0001] The invention relates to a device for processing steel structure parts, in particular to a tubular pipe hole cutter with convenient operation, good processing quality, low processing cost, greatly improved working environment and reduced labor intensity. Background technique [0002] As we all know, for large-scale foundation piles (bridge piers, offshore working platforms), steel plates are generally used to make cylindrical pile legs, and there are a number of corresponding through-holes on the wall of the cylinder. The through-holes are used to connect the poles or conduct convection. The processing of pile legs is to bend and weld the steel plate into a cylindrical shape, and then use gas cutting welding to open the convection energy hole on the wall of the cylinder, and sometimes it is necessary to perform bevel treatment on the periphery of the convection hole to reduce the water flow resistance or facilitate the connection with the pile.

[0002] As we all know, for large-scale foundation piles (bridge piers, offshore working platforms), steel plates are generally used to make cylindrical pile legs, and there are a number of corresponding through-holes on the wall of the cylinder. The through-holes are used to connect the poles or conduct convection. The processing of pile legs is to bend and weld the steel plate into a cylindrical shape, and then use gas cutting welding to open the convection energy hole on the wall of the cylinder, and sometimes it is necessary to perform bevel treatment on the periphery of the convection hole to reduce the water flow resistance or facilitate the connection with the pile. Other parts are welded together, and the convection holes are processed manually in the cylinder by cutting and welding. The disadvantages are complicated operation, low processing efficiency, poor processing quality, high labor intensity of workers, and harsh working environment.
