Welded pipe electric welding machine with excellent cooling effect

Abstract

The invention provides a welded pipe electric welding machine with an excellent cooling effect and relates to the field of welded pipe machining. The welded pipe electric welding machine with the excellent cooling effect comprises a first box body, a second box body and cooling boxes, wherein an electric welding machine assembly is arranged inside the second box body; the second box body is positioned in the first box body; two symmetrically distributed cooling boxes are arranged in a gap between the first box body and the second box body; the two cooling boxes are respectively mounted on the outer wall of the second box body; a first air outlet pipe is arranged on the top of the cooling boxes; one end of the first air outlet pipe penetrates through the cooling boxes and extends into the cooling boxes; one side of the outer wall of the first air outlet pipe is communicated with an exit pipe; and one end, which is far away from the first air outlet pipe, of the exit pipe sequentially penetrates through the cooling boxes and the second box body and extends into the second box body. According to the welded pipe electric welding machine with the excellent cooling effect, a cyclic refrigerating effect is achieved, the temperature of the electric welding machine assembly is reduced, and the service life of the electric welding machine is prolonged.

Description

Technical field [0001] The invention relates to the technical field of welded pipe processing, in particular to a welded pipe electric welder with a good cooling effect. Background technique [0002] Welded pipe is a device for conveying gas, liquid or fluid with solid particles connected by pipes, pipe couplings and valves. Generally, the fluid is pressurized by blowers, compressors, pumps, boilers, etc., and then flows from the high pressure of the welded pipe to the low pressure. The fluid can also be transported by its own pressure or gravity. Welded pipes have a wide range of uses, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. [0003] Welded pipe welding machines are mostly used to connect welded pipes, but most of the current welders on the market have insufficient heat dissipation. For example, the Chinese patent discloses ...

AI Technical Summary

Problems solved by technology

[0003] Welding pipe welding machines are mostly used for the connection of welded pipes, but the heat dissipation of most of the welding machines on the market is not good enough. The energy-saving electric welding machine includes an electric welding machine, which is mainly characterized in that an electromagnetic relay is connected in series in the secondary circuit of the electric welding machine, and a heat dissipation fan is connected in series in the primary circuit of the electric welding machine, and the heat dissipation fan is installed on the top of the electric welding machine. It can blow air downward to dissipate heat for the welding machine. The two circuit terminals of the electromagnetic relay in the secondary circuit are connected in series in the primary heat dissipation fan.

Although the above-mentioned patent has simple structure and easy to use, when the electric welding machine is unloaded, the secondary circuit is not connected, so that the relay does not work; The fan runs to take away the heat of the welding machine, but this patent cannot circulate heat dissipation, and only one cooling fan cannot guarantee the cooling effect, and the cooling effect is not ideal, which will have a certain impact on the service life of the welding machine
