A seamless welding machine

Abstract

The invention discloses molecular staggered seamless welding machine equipment. The equipment comprises a main body, wherein a welding cavity is formed in the main body, a matching block is rotationally arranged in the welding cavity, the matching block is divided into an upper part and a lower part, the upper matching block and the lower matching block which correspond to each other vertically are connected through a screw rod, a welding gear capable of driving the matching block to rotate is arranged on the outer wall of the matching block, and bilaterally symmetrical upper fixing blocks arearranged in the welding cavity in a sliding mode. According to the equipment, the device is simple in structure, convenient to operate and maintain and continuous in welding process, integral connection of to-be-welded metal is guaranteed during welding, welding strength is greatly improved, meanwhile, personnel intervention is not needed in the welding process, dependence on the welding technology of welding personnel is reduced, personnel cost is reduced, rotating operation is not conducted on the welded metal during welding, the length range of weldable metal is greatly widened, the application capacity of the equipment is improved, and therefore the equipment has high use and popularization value.

Description

technical field [0001] The invention relates to the field of welding, in particular to a seamless welding machine. Background technique [0002] With the continuous development of social infrastructure, metal materials with longer length and higher strength are constantly required, and then longer metal materials are not easy to transport, and the cost increases; [0003] When a longer length of metal material needs to be used, welding is often used to extend the length of the material. However, the traditional welding method can only connect the metal surfaces at both ends, the welding strength is not high, and the technical requirements for the welding personnel are high. The new welding method has a limited extension length and a lower applicable range. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a seamless welding machine, which can overcome the above-mentioned defects of the prior art. [0005] A seamless welding machine incl...

[0002] With the continuous development of social infrastructure, there is a constant need for longer length and higher strength metal materials, and then longer metal materials are not easy to transport, and the cost increases;

[0003] When it is necessary to use a longer length of metal material, welding is often used to extend the length of the material. However, the traditional welding method can only connect the metal surfaces at both ends, the welding strength is not high, and the technical requirements for welding personnel are high. The extension length of the new welding method is limited, and the applicable range is low
