Problems solved by technology

But if the steel pipe is placed vertically, the steel pipe will be easily separated from the driving wheel and the driven wheel, and it is not easy to weld. The machine is improved to facilitate stable and efficient welding when the steel pipe is in a vertical state

Embodiment 1

[0036] Such as figure 1 with 2 As shown, a fully automatic pipe end argon arc welding machine includes a frame 1, on which a mounting plate 2 is vertically fixed by screws, and a steel pipe 3 to be welded is vertically arranged on the mounting plate 2, the steel pipe 3 A pipe cap to be welded is installed on the upper end of the steel pipe, and one side of the mounting plate 2 is provided with an upper positioning structure and a lower positioning structure that can rotate the steel pipe 3 in the circumferential direction and position it axially, and the upper positioning structure is directly above the lower positioning structure. Between the upper positioning structure and the lower positioning structure, there is a rotating mechanism that can make the steel pipe 3 rotate circumferentially. The side of the mounting plate 2 is fixed with a welding torch 13 through a fixed structure. The muzzle of the welding torch 13 faces the upper end of the steel pipe 3, and the mounting p...

Embodiment 2

[0056]The structure and principle of this embodiment are basically the same as that of the first embodiment, the difference is that in the first embodiment, the pressing and holding mechanism includes a pressing wheel 16, a cylinder one 14 and a pressure rod 15; and in the second embodiment , the pressing and holding mechanism includes a pressing wheel 16, a push rod motor and a connecting rod. All on the same plane with the driven wheel 7, the other end of the connecting rod is hinged on the mounting plate 2, the push rod of the push rod motor is hinged on the middle part of the connecting rod, and the push rod motor is hinged on the mounting plate 2. In this embodiment, the holding mechanism always presses the steel pipe 3 on the driving wheel 6 and the driven wheel 7 in this way: the push rod of the push rod motor stretches out, and the connecting rod is close to the driving wheel 6 and the driven wheel 7 , the pressing wheel 16 moves toward the driving wheel 6 and the driv...

Abstract

The invention provides a full-automatic pipe end argon arc welding machine, and belongs to the technical field of welding equipment. The full-automatic pipe end argon arc welding machine solves the problem that an existing argon arc welding machine can not achieve automatic welding on steel pipe annular welding joints in the vertical direction. The full-automatic pipe end argon arc welding machine comprises a machine frame. An installation plate is vertically fixed on the machine frame. The full-automatic pipe end argon arc welding machine is characterized in that an upper locating structure and a lower locating structure are arranged on the installation plate, the upper locating structure and the lower locating structure enable a steel pipe to circumferentially rotate and be axially located, a rotation mechanism capable of enabling the steel pipe to circumferentially rotate is further arranged between the upper locating structure and the lower locating structure, a welding gun is fixed on the installation plate through a fixing structure, a gun opening of the welding gun is arranged towards the upper end of the steel pipe, and a pressing and holding mechanism capable of enabling the steel pipe to always abut against a driving wheel and a driven wheel is further arranged on the installation plate. According to the full-automatic pipe end argon arc welding machine, automatic welding on the steel pipe annular welding joints can be achieved in the vertical direction. The full-automatic pipe end argon arc welding machine is convenient to operate and high in efficiency, and the labor intensity of workers is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and relates to a full-automatic pipe end argon arc welding machine. Background technique [0002] Argon arc welding technology is based on the principle of ordinary arc welding, using argon gas to protect the metal welding material, and through high current to make the welding material melt into a liquid state on the base material to be welded to form a molten pool, so that the welded metal and the welding material It is a welding technology that achieves metallurgical combination of materials. Since argon gas is continuously supplied during high-temperature fusion welding, the welding materials cannot be in contact with oxygen in the air, thereby preventing the oxidation of the welding materials. Therefore, stainless steel and iron metals can be welded. . According to the different electrodes, argon arc welding is divided into two types: melting pole argon arc welding and non-melting ...
