Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of metal pipe processing, and particularly relates to a pipe bending and welding device for metal product processing. Background Art
[0002] A metal bent pipe is a tubular member with a bent shape made of metal materials. Common metal bent pipe materials include stainless steel, carbon steel, alloy steel, etc. Different materials have different characteristics. For example, stainless steel bent pipes have advantages such as corrosion resistance, high temperature resistance, and high strength, and are widely used in industries such as new energy vehicles; carbon steel bent pipes have relatively low costs and high strength, and are suitable for general industrial pipe systems. Currently, there are many forming methods for metal bent pipes, including the grooved wheel rolling method, induction heating bending method, die pressing method, progressive forming method, numerical control pipe bending method, and welding forming method. Among them, the welding forming method is also a relatively common forming method at present. The principle of pipe bending welding is mainly based on the melting and solidification process of metals. During the welding process, the solder is heated to a molten state and flows along the joint between the bent pipe and other metal base materials under the action of capillary force, forming tiny uneven crystals and adhering to the surface of the base material. As the solder cools and solidifies, a diffusion phenomenon occurs between the solder and the base material, forming a metal compound layer, thereby achieving a firm connection. Pipe bending welding is widely used in various pipe systems, such as oil pipelines, gas pipelines, liquid pipelines, and engineering bridge construction. Through pipe bending welding technology, flexible connection and efficient operation of pipe systems can be achieved.
[0003] For the welding between a bent pipe and a straight pipe commonly seen in the market, most of them are manually welded. It is necessary to align one end of the bent pipe with one end of the straight pipe, and then the worker welds. However, during the welding process, it is necessary to rotate the bent pipe and the straight pipe. Affected by the shape of the bent pipe, when rotating the bent pipe, it is often necessary to hold the bent pipe while welding, which is rather troublesome and prone to mistakes during the welding process, resulting in a significant decrease in welding efficiency.
