A high-precision automatic flanging equipment

Abstract

The invention discloses a high-precision automatic flanging equipment, comprising: a pipe clamping mechanism for clamping and fixing the flanged pipe; a mold rotating mechanism for rotating and rotating different molds, so as to realize the matching of different molds. Pipe heating, flanging, and trimming operations; control the drive mechanism, which is used to control the feeding action of the mold and realize the back and forth sliding of the mold. The patent provides a high-precision automatic flanging equipment, which integrates heating, flanging and trimming into one device, and the automatic operation not only ensures the flanging quality, but also greatly improves the flanging efficiency. With convenient operation, high degree of automation and precise product quality control, it not only has high flanging accuracy but also is suitable for mass production, solving the problems that cannot be solved by existing flanging machines on the market.

Description

technical field [0001] The patent of the invention belongs to the field of plastic pipe manufacturing equipment, and particularly relates to a high-precision automatic flanging equipment. Background technique [0002] In the oil field, countless pipelines are scrapped each year due to corrosion of metal pipelines. Because the medium in the oil is complex and contains many chemical components, in order to reduce the corrosion of the metal pipeline, it is better to lining the plastic pipe inside the steel pipe to avoid the contact between the crude oil and the steel pipe, and to improve the oil barrier and resistance of the pipeline as a whole. Corrosive. However, in the field of oil transportation in my country, the plastic pipe lined steel pipe is currently limited to the oil pumping pipe, and has not been applied to the gathering and transportation pipelines with large consumption. Since the operation mode of the sucker pipe is that the sucker rod is pulled in the pipe, t...

AI Technical Summary

Problems solved by technology

The flanging treatment is to prevent the medium from entering the space between the lined plastic pipe and the metal pipe from the joint, which will lead to the collapse and failure of the lined plastic pipe in the long run, which will cause the lined pipe to fall off and the pipe to be scrapped

At present, there are many flanging devices on the market, but most of them are used for flanging of PVC, PE and other pipes, not for flanging of lined pipes, and the existing devices cannot be applied to the mass production of flanging of lined pipes due to some defects.

For example, Patent No. CN03261894.8 discloses a plastic pipe flanging machine. This device is used for flange connection, but cannot be used for lining pipe flanging, and this device is a manual device, which cannot guarantee the consistency of pipe flanging products. characteristics, and cannot be applied to mass production

After the existing flanging machine is used for the flanging of the inner liner, the redundant edge needs to be manually trimmed, and there are uncertain factors in the operation of the workers, the process is uncontrollable, and the original flanging is easily damaged during the trimming, resulting in leakage at the flanging , the liner collapsed
