Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting, in particular to a pipe cutting device with a peeling function. Background Technique

[0002] When recycling and reusing pipes, it is necessary to cut and classify the pipes, and the anticorrosive coating on the outer surface of the pipes needs to be scraped off before cutting.

[0003] The Chinese patent discloses a natural gas pipe cutting machine with an anticorrosive coating peeling function, with the publication number CN218612767U, which includes side support plates and a pipe arranged inside them. A peeling mechanism is provided at the lower end of the pipe. The peeling mechanism includes a scraping plate that abuts against the outer wall of the pipe. A rotation and support mechanism is also provided inside the side support plates. When the anticorrosive coating needs to be peeled, the flame sprayer will preheat the outer wall of the pipe by spraying fire, and then the electric push rod will push the cutting edge end of the scraping plate directly into the softened anticorrosive coating. As the pipe continues to rotate, the anticorrosive coating on its outer wall will be removed one by one. The elastic abutment between the scraping plate and the outer wall of the pipe can be formed by the spring pressing leg, which not only prevents scratches on the outer wall of the pipe but also enables the scraping plate to tightly enter the junction of the anticorrosive coating and the pipe, so as to remove the anticorrosive coating as much as possible. The structure is simple and easy to operate, greatly improving the peeling efficiency of the pipe anticorrosive coating.

[0004] However, it still has the following disadvantages: The device uses a servo motor to drive the pipe to rotate, but the device cannot convey the pipe. After the pipe peeling and cutting operation, the pipe needs to be manually fed, which increases the labor intensity of workers and reduces the processing efficiency of the device. For this reason, we propose a pipe cutting device with a peeling function to solve this problem. Content of the Utility Model
