Pipe bending preventing device used for corrugated forming machine

Abstract

The invention discloses a pipe bending preventing device used for a corrugated forming machine. The pipe bending preventing device comprises a bottom plate. A corrugated module is arranged on one side of the bottom plate. A corrugated pipe is movably arranged in the corrugated module. An air inlet pipe is arranged on one side of the corrugated module and internally sleeved with a supporting pipe. A bladeless fan is arranged on one side of the air inlet pipe. According to the pipe bending preventing device used for the corrugated forming machine, an exhaust fan and a water tank are arranged, so that the corrugated pipe is preliminarily cooled beneficially, the situation that the corrugated pipe is deformed due to the fact that the corrugated pipe collides the supporting pipe is avoided, a pungent smell produced through machining of the corrugated pipe is exhausted beneficially, the environment is purified, and the harm of the pungent smell to the human health is avoided; the air inlet pipe and the supporting pipe are arranged, and thus sufficient and uniform air supply and cooling are conducted from the exterior and the interior of the corrugated pipe beneficially; the bladeless fan is arranged, so that air is blown to cool the corrugated pipe beneficially, and discharging is convenient; and springs and gaskets are arranged, so that the supporting pipe is selected or replaced according to corrugated pipes with different diameters beneficially, and the situation that the corrugated pipe is deformed in the supporting pipe due to the fact that the diameter of the supporting pipe is too large is avoided.

Description

technical field [0001] The invention relates to the technical field of corrugated pipe processing, in particular to a pipe bending prevention device for a corrugated forming machine. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets made of plastic along the direction of folding and expansion. Bellows are widely used in instruments and meters, and their main purpose is as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, and the measurement range is tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and the auxiliary coil spring or spring leaf is used to increase the elasticity. At present, when some corrugated pipes with large diameters are produced, the pipes need to be heated during production. After the corrugation is formed, the outer wall and internal tem...

AI Technical Summary

Problems solved by technology

At present, when some corrugated pipes with large diameters are produced, the pipes need to be heated during production. After the corrugation is formed, the outer wall and internal temperature of the pipes are high, and it is easy to bend when discharging. After cooling, the pipes are set and difficult to return to their original shape. , therefore, it is necessary to invent an anti-pipe bending device for corrugation forming machines to solve the above problems
