Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PE corrugated pipe processing, in particular to a PE corrugated pipe cutting device. Background Art
[0002] The corrugated pipe is a circular profile with a corrugated outer circumference and an uneven outer circumferential surface. The application of the corrugated pipe is very wide, and it is widely used in municipal engineering, farmland water conservancy irrigation and water supply, chemical ventilation pipes, communication cable maintenance pipes, cement, metallurgy and other industries.
[0003] For the cutting equipment of the corrugated pipe, when cutting the corrugated pipe, if the corrugated pipe is clamped too tightly, it is easy to cause the corrugated pipe to deform. If it is clamped loosely, the corrugated pipe will vibrate during the cutting process, which is easy to cause inaccurate processing problems and affect the processing quality. Therefore, in the cutting process, the fixing and clamping of the corrugated pipe is very important. However, most of the current devices are difficult to meet the requirements, thereby failing to improve the cutting efficiency. In addition, one device cannot process corrugated pipes of multiple different diameters, which reduces the applicability of the device. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
