Manufacturing and machining device and machining method for high-density polyethylene HDPE double-wall corrugated pipe

Abstract

The invention relates to a manufacturing and machining device and a machining method for a high-density polyethylene HDPE double-wall corrugated pipe. The device comprises a workbench and supporting frames symmetrically arranged at the centers of the front end and the rear end of the bottom of the workbench, wherein an outer grinding device is arranged above the supporting frames, an inner grinding device is arranged above the workbench, and a cleaning device is arranged between two sets of rectangular baffles. According to the device, guide rods, bidirectional screw rods, first grinding rollers and first arc-shaped plates are matched so that the two sets of first grinding rollers can move oppositely under the thread driving of the bidirectional screw rods and the guide action of the guide rods, the corrugated pipe to be machined is jacked to the position above the workbench, burrs on the outer wall of the corrugated pipe to be machined are ground, the first arc-shaped plates rotate along with the first grinding rollers, the burrs in grooves in the outer wall of the corrugated pipe to be machined can be ground, the size precision of the corrugated pipe is improved, the situation that the burrs in the grooves are not removed, and consequently installation of the corrugated pipe is affected is avoided, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the field of pipe material processing, in particular to a high-density polyethylene (HDPE) double-wall corrugated pipe manufacturing and processing equipment and processing method. Background technique [0002] High-density polyethylene, referred to as HDPE, also known as low-pressure polyethylene, is a kind of translucent with high crystallinity and a certain degree of non-polar surface. PE has excellent resistance to most domestic and industrial chemicals. [0003] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and expansion. It is widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries. A bellows is a tube with a series of parallel ridges and grooves on its surface. The tube can be made of steel or plastic such as high density polyethylene (HDPE) or PVC. It comes in various diamete...

AI Technical Summary

Problems solved by technology

[0005] 1. Due to the grooves on the surface of the existing bellows, it is inconvenient to grind the burrs in the grooves, and manual grinding is often required. The grinding process is complicated and reduces the work efficiency;

[0006] 2. When the existing grinding device grinds the inner wall of the bellows, it can only grind the bellows with a single diameter. The applicable occasions are very limited, which reduces the applicable value of the grinding device and greatly increases the production cost.
