Full-automatic corrugated pipe tempering furnace

Abstract

The invention discloses a fully automatic tempering furnace for bellows, which comprises a discharge turntable, a collection turntable, a tempering furnace and a driving motor. One end of the bellows is wound on the discharge turntable. There is a furnace, and the other end of the bellows passes through the furnace of the tempering furnace and is wound on the collecting turntable. There is a second sprocket, the drive motor is connected to the first sprocket through the first chain, the first sprocket and the second sprocket are closely offset, the second sprocket is connected to the reciprocating screw rod through the second chain, and the reciprocating screw rod is set There is a slide block, a pipe sleeve is installed on the slide block through a connecting rod, and the pipe sleeve is set on the bellows. The invention can automatically temper the bellows, simplifies the operation, shortens the time and manpower, greatly improves the production efficiency of the whole bellows, and reduces the generation of cracks in the bellows.

Description

technical field [0001] The invention relates to the technical field of corrugated pipes, in particular to a fully automatic tempering furnace for corrugated pipes. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and stretching. Its open end is fixed, and the sealed end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. When working, under the action of internal pressure, it is elongated along the length of the pipe, so that the movable end produces a displacement that has a certain relationship with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often combined with displacement sensors to form a pressure sensor whose output is electricity, and are sometimes used as an isolation element. [0003] At present, the existing production process of stainless steel bellows is feeding,...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing production process of stainless steel bellows is feeding, welding and forming, tempering and cooling, drying, cutting, turning over, inspection, packaging and storage. However, after the existing production of bellows is welded and formed, it needs to be manually Tempering, to avoid oxidation on the surface of the bellows, the process is more complicated, requires multiple processing operations, labor-intensive, and low production efficiency; and it is easy to cause oxidation of the bellows during heat treatment, reducing the elastic properties of the bellows; during the welding process , it is easy to cause printing cracks, and its strength is lower than that of seamless stainless steel bellows

It requires multiple tedious operations, which is time-consuming and labor-intensive, which greatly affects the production efficiency of the entire bellows and increases the occurrence of cracks in the bellows
