Powder blowing device at inlet of welding machine

Abstract

The invention belongs to the field of welding machines, and particularly relates to a powder blowing device at an inlet of a welding machine. The powder blowing device comprises a blowing beam, air blowing holes and a blowing unit; the air blowing holes are uniformly formed in the blowing beam; the blowing unit is arranged on the blowing beam; the blowing unit comprises a base pipe, a cover pipe, a steel ball, an exhaust hole and a guide pipe; the base pipe is fixedly connected to the air blowing holes in a threaded sealing mode; and the base pipe is in threaded sealing connection with the cover pipe. The angle of the guide pipe can be changed through damping rotation of the steel ball in the base pipe and the cover pipe, so that the air blowing position can be accurately adjusted to remove iron oxide powder, compressed gas can be saved, an air pipe is more convenient to connect and disassemble through a built-in pneumatic connector, the built-in pneumatic connector is arranged, so that the blowing beam is high in appearance integrity, free of protrusions and convenient to install and use, the problem that the welding quality is low due to the fact that iron oxide powder is not removed in traditional welding is solved, and the quality of welding seams is improved.

Description

technical field [0001] The invention relates to the field of welding machines, in particular to a powder purging device at the entrance of a welding machine. Background technique [0002] The purging device is generally a device used to remove dust, and generally uses compressed air and a brush as the cleaning medium. [0003] Welding machine refers to equipment that provides power for welding. Welding is a connection method that uses high-temperature current to melt electrodes to connect two metals with high strength. [0004] When the welding machine at the entrance of the acid rolling line is welding, the welding quality is often affected by the accumulation of iron oxide powder near the weld, which makes the welding quality low; therefore, a powder purging device at the entrance of the welding machine is proposed to solve the above problems.
