Pipe rounding device

Abstract

The invention relates to the field of pipe machining, in particular to a pipe rounding device. The pipe rounding device comprises a workbench. The workbench is provided with a base for containing a pipe. The upper end surface of the base is provided with a groove matched with the lower surface of the pipe. The groove is in a circular arc shape and is internally provided with a heating layer. A supporting rod for shaping the pipe is arranged above the base and comprises a front segment and a back segment, and the front segment and the back segment are connected through a clamping connector. A plurality of pushing rods are arranged in the circumferential direction of the supporting rod. First gears are arranged at the two ends of the supporting rod correspondingly. Brackets are arranged on the two sides of the base. A rotating shaft is rotationally connected to each bracket. One end of each rotating shaft is provided with a motor, and the other end of each rotating shaft is sleeved with a second gear engaged with the corresponding first gear. The workbench is provided with a sliding rail. The brackets are slidably connected with the sliding rail. According to the pipe rounding device, secondary forming is conducted on the pipe in a local high-temperature heating mode, the process is simple, and resources are saved.

Description

technical field [0001] The invention relates to the field of pipe processing, in particular to a pipe rounding device. Background technique [0002] Pipes are necessary materials for construction projects. Commonly used are water supply pipes, drainage pipes, gas pipes, heating pipes, wire conduits, rainwater pipes, etc. With the development of science and technology, most pipes have also developed from metal materials to plastic materials. At present, the processing of pipes mainly includes feeding, high-temperature forming, low-temperature vacuum setting, traction and fixing, cutting, stacking and other links. The processing and collection of pipes are completed through the above process links. However, in the process of low-temperature vacuum setting The degree of spraying will be uneven, resulting in different degrees of shrinkage of the pipes, so that the shape of the pipes is not round. Now, for such pipes that do not meet the requirements, they are mostly placed asid...

Problems solved by technology

At present, the processing of pipes mainly includes feeding, high-temperature forming, low-temperature vacuum shaping, traction fixing, cutting, stacking and other links. The processing and collection of pipes are completed through the above process links. However, in the process of low-temperature vacuum shaping The degree of spraying will be uneven, resulting in different degrees of shrinkage of the pipes, so that the shape of the pipes is not round. Now, for such pipes that do not meet the requirements, they are mostly placed aside as waste products, which is a waste of materials; or the pipes are heated again. Melt and re-extrude, the process is more complicated
