A kind of metal bellows outer wall rust removal and grinding machine

Abstract

The invention relates to the technical field of corrugated pipe grinding and manufacturing, and specifically relates to a metal corrugated pipe outer wall derusting and grinding machine, which is equipped with a bottom plate, a traction device, a grinding device and a cleaning device to complete the derusting of the outer wall of the bellows; the present invention can be Solve the problem of manual grinding and derusting directly, resulting in slow manual grinding and derusting speed, and it is difficult to polish the depression of the bellows, resulting in insufficient derusting of the outer wall of the metal bellows, and the existing rust removal machinery for the outer wall of the metal bellows Usually, the outer wall of the bellows is directly polished by the grinding mechanism, and the impurities bonded to the outer wall of the bellows are not removed, which may easily cause the impurities to scratch the outer wall of the bellows, and the waste debris under grinding is not cleaned after grinding, which may easily lead to The corrugated pipe will rust again when it is used.

Description

technical field [0001] The invention relates to the technical field of bellows grinding and manufacturing, in particular to a machine for removing rust and grinding the outer wall of metal bellows. Background technique [0002] Metal bellows is a regular wavy pipe. Commonly used metal bellows are made of carbon steel and stainless steel, as well as plastic and aluminum. Metal bellows are mainly used for non-concentric axial transmission with small bending radius, irregular turning, expansion and contraction, absorption of thermal deformation of pipes, etc., and for occasions where it is not convenient to install with fixed elbows for pipe-to-pipe connection and pipe-to-pipe connection In the connection and use of equipment, etc., the outer wall of the metal bellows is prone to rust, and it needs to be polished and derusted before use. [0003] When grinding and derusting the outer wall of the metal bellows through the existing bellows derusting technology, the following pro...

AI Technical Summary

Problems solved by technology

[0003] When grinding and derusting the outer wall of the metal bellows through the existing bellows derusting technology, there are often the following problems: (1) When manually grinding and derusting the outer wall of the metal bellows, usually directly by using an angle grinder or Grinding and derusting the outer wall of the metal bellows with sandpaper, etc., due to the spiral protrusions on the outer wall of the metal bellows, the speed of manual grinding and derusting is slow, and it is difficult to polish the depressions of the bellows, resulting in insufficient derusting of the outer wall of the metal bellows , affecting the use of metal bellows

[0004] (2) When the outer wall of the bellows is derusted by the existing metal bellows outer wall derusting machine, the outer wall of the bellows is usually directly polished by the grinding mechanism, and the impurities bonded to the outer wall of the bellows are not removed before the existing mechanical grinding Cleaning, impurities are likely to cause scratches on the outer wall of the bellows during grinding, and after the grinding is completed, the waste debris under the surface of the bellows is not cleaned, and the remaining waste is likely to cause the bellows to rust again when used
