A kind of linear flame welding machine and its welding method

Abstract

The invention discloses a linear flame welding machine. The linear flame welding machine comprises a feeding mechanism, a welding mechanism and a discharging mechanism; the feeding mechanism comprisesa feeding table, a storing table and a pushing device; the welding mechanism comprises a welding room supporting frame and welding assemblies; each welding assembly comprises a welding head set, a longitudinal adjusting assembly and a transverse adjusting assembly; and the discharging mechanism comprises a discharging table, a material conveying device and a material table. A welding method comprises the following steps of (1) feeding of welded workpieces; (2) adjustment of the height of the welding assemblies; (3) adjustment of the position of the welding head sets; (4) welding; and (5) discharging of the welded workpieces. The linear flame welding machine is ingenious and reasonable in structural design, and convenient and rapid to use and operate, achieves automatic treatment operationof workpiece feeding and discharging through the feeding mechanism and the discharging mechanism, relieves labor intensity, improves operation safety performance, can conduct welding on the workpieces at the same time through design of the multiple welding assemblies, effectively increases the welding rate, and improves the work efficiency.

Description

Technical field [0001] The invention relates to a linear flame welding machine and a welding method thereof. Background technique [0002] Welding, also known as welding or welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. With the development of industry and science and technology, the welding process and requirements of various high melting point, high strength and active metals, alloy welding, dissimilar metals and precision and complex structural parts are getting higher and higher. Different metals and workpieces with different structures require corresponding welding processes and equipment to implement welding. There are many energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction, and ultrasonic. In addition to being used in factories, welding can also be carried out in a variety of environments, such as the fi...

Problems solved by technology

[0003] The existing production methods of direct-fired electric welding machines are relatively backward, and most of them use manual loading and unloading, which is extremely inefficient, wastes manpower and material resources, and has certain dangers, especially after electric welding. The temperature is high, and it needs to be cooled for a period of time before it can be transported, which affects the working efficiency
