Technical Field
The invention relates to the field of welding machines, in particular to a submerged arc welding machine capable of automatically feeding wires and an operation method.
Background
Welding, also known as fusion welding, is a manufacturing process and technique for joining metals or other thermoplastic materials, such as plastics, by means of heat, high temperature or high pressure. The energy sources for modern welding are many, including gas flame, electric arc, laser, electron beam, friction, and ultrasonic, among others. In addition to use in a factory, welding can be performed in a variety of environments, such as the field, underwater, and space. Wherever welding can be dangerous for the operator, appropriate precautions must be taken while welding is being performed. The possible injuries to human body caused by welding include burn, electric shock, visual impairment, toxic gas inhalation, over-irradiation of ultraviolet rays, etc.
Submerged arc welding (including submerged arc welding, electroslag welding, and the like) is a method in which an electric arc is burned under a flux layer to perform welding. The welding method has the advantages of stable inherent welding quality, high welding productivity, no arc light, little smoke and the like, and becomes a main welding method in the manufacture of important steel structures such as pressure vessels, pipe sections, box-type beam columns and the like. In recent years, although many new welding methods with high efficiency and high quality have been developed, the application field of submerged arc welding is still not affected at all.
The existing submerged arc welding machines all automatically feed welding wires, labor is saved, but the existing wire feeding devices all adopt a single wire reel, if the welding wire is required to stop welding work after being used up in the welding process, a new wire reel is manually replaced, so that the welding process is reduced, and the welding quality is greatly reduced when the welding work is suddenly stopped.

10. The method of operating an automated wire feed submerged arc welding machine of claim 1, wherein: the method comprises the following steps:
s1, two wire reels (4) are installed at the same time, welding wires on one wire reel (4) pass through the two-way wire feeder (3) and are sent to a position between the early warning induction wire feeding wheels (2), then the welding wires on the other wire reel (4) are inserted into the two-way wire feeder (3) and pass through the wire feeding reels (5), and the telescopic rod (8) is started through the control processor, so that the telescopic rod (8) pushes the wire clamping plate (9) to clamp the welding wires;
s2, in normal wire feeding work, the two opposite early warning induction wire feeding wheels (2) continuously feed the welding wire downwards, the pressure sensor (204) inside the early warning induction wire feeding wheels (2) is continuously pressed by the feeler lever (205), after the welding wire is fed, the pressure sensor (204) is not pressed and is interrupted, and at the moment, the pressure sensor (204) sends a signal to the control processor to enable the servo motor (6) to be started;
s3, the servo motor (6) drives the pulley (7) to rotate, the wire feeding disc (5) clamps the welding wire to move downwards, the lower end of the welding wire is fed between the two early warning induction wire feeding wheels (2), and the welding wire is automatically connected by virtue of the clamping force.
