Automatic welding device for nanometer thin-wall pipe fitting

Abstract

The invention discloses an automatic welding device for a nanometer thin-wall pipe fitting. The automatic welding device comprises a base, wherein a lifting plate is arranged at the top of the base, supporting conveying mechanisms are arranged at the two ends of the top of the lifting plate correspondingly, a first hydraulic cylinder is fixedly installed between the lifting plate and the base, a welding machine is arranged at the top of the base, a second hydraulic cylinder is fixedly installed at the bottom of the welding machine, a welding gun is fixedly connected to the bottom end of the second hydraulic cylinder, each supporting conveying mechanism comprises a supporting base, the supporting bases are rotationally connected to the top of the lifting plate, and gear teeth are arranged on the circumferential side of the bottom end of each supporting base. By means of rotation of the supporting bases, two sets of supporting idler wheels can change states continuously, moving and rotating control over a to-be-welded pipe is achieved, and then the processes of automatic feeding, aligning, seam aligning, automatic welding and automatic discharging of the to-be-welded pipe are achieved, so that the practicability and convenience of using the device are improved.

Description

technical field [0001] The invention relates to the technical field of pipe fitting welding, in particular to an automatic welding device for nanometer thin-walled pipe fittings. Background technique [0002] Thin-walled tubes are made of steel ingots or solid tube billets through perforation, and then hot-rolled, cold-rolled or cold-drawn. In order to improve certain properties of thin-walled tubes, thin-walled tubes are usually combined with modern nano The combination of technologies, such as nano-spraying, nano-plating and other technical processes, such products can be called nano-tubes, and along with the high-level application and development of nano-materials, nano-technology has also been widely used; [0003] The prior art has the following deficiencies: according to different actual places of use, thin-walled pipe fittings need to be welded or cut during production to achieve a suitable length for use. However, due to the low strength of thin-walled pipes, when we...

Problems solved by technology

[0003] The prior art has the following deficiencies: according to different actual places of use, thin-walled pipe fittings need to be welded or cut during production to achieve a suitable length for use. However, due to the low strength of thin-walled pipes, when welding them Difficult to clamp effectively. If the force is too high, it is easy to cause damage to the pipe fittings, resulting in welding failure. Therefore, it is difficult to automatically weld, resulting in low welding efficiency. However, the existing welding equipment is difficult to adapt to a variety of pipe fittings of different sizes. limitation
