The mechanical industry analysts pointed out that the product structure of domestic pipe bender and metal circular saw industry has been continuously optimized and presented three major characteristics: first, with the continuous development of industry and technology, the pipe shrinking machine products have shown the trend of development in the direction of large (heavy) and super-heavy; Second, medium and high grade high speed and high precision forming machines have become the mainstream and focus of market demand.
With the development and progress of science and technology, the machine tool products of the pipe bender and pipe processing machinery industry also have a leap forward in reform and renewal, which is due to the demand of China for the pipe bender and pipe processing machinery and equipment industry in recent years. In recent years, with the progress and development of China's society, the pipe bender and other machine tool industries have been vigorously developed in many related supporting facilities industries. The pipe bender, pipe cutter, pipe shrinking machine and other pipe processing equipment are facing the development of pipe bender, hydraulic pipe bender, automatic pipe bender and CNC pipe bender in the face of years of scientific and technological research and innovation.
Our pipe bender industry involves the processing needs of various industries, so we should make innovation and progress in flexibility and versatility. In this way, the single pipe bender, single end pipe bender and hydraulic pipe bender cannot meet the needs of comprehensive development. Therefore, CNC pipe benders and automatic pipe benders have been developed along with them. In the past, imported pipe benders have been relied on to support the demand of high-tech industries.
At present, we can completely develop and manufacture independently, and also customize for users. Relevant models are matched according to the material and processing characteristics. It can be reconstructed or completely designed on the original model.
There are many different pipe bending processes of pipe bender in practice, and there are many different classifications from different angles. In the project, cold bends and hot bends are generally divided according to whether the bends are heated or not. The bends are divided into cored bends and coreless bends according to whether there is filler during bending. The cold bending method is used for bending stainless steel pipes, especially thin-walled stainless steel pipes.
The cold bending method is to bend the pipe under normal temperature. Because the pipe bender does not need heating when bending, it is more suitable for bending stainless steel pipe, aluminum pipe and copper pipe. The commonly used cold bending method is rolling bending (rounding machine - winding machine). Pull-wound bending, push-wound bending and pressure bending, etc. Now the related problems of pipe fittings in the process of stretch-wound bending are mainly introduced. Generally, the bending radius of cold bending shall not be less than 1.5 times of the pipe diameter. Because the pipe has certain elasticity. However, after the external force applied during bending is eliminated, the pipe will bounce back at an angle, and there must be a certain amount of over-bending rebound during bending. The rebound amount is related to the mechanical properties of the pipe material, wall thickness and bending radius. Generally, the rebound angle is about 2-5 degrees when the copper pipe is bent.
