Description

Clamping device is used in bellows processing

Technical Field

The utility model relates to a clamping device technical field is used in the bellows processing, specifically is a clamping device is used in bellows processing.

Background

The corrugated pipe is a tubular elastic sensitive element which is formed by connecting foldable corrugated sheets along the folding and stretching direction. The corrugated pipe has wide application in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thin pipe wall and high sensitivity, and the measurement range is from tens of Pa to tens of MPa. Its open end is fixed, its sealed end is in free state, and its elasticity is increased by using auxiliary helical spring or reed. When working, the pipe is extended along the length direction under the action of internal pressure, so that the movable end generates displacement in a certain relation with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often combined with displacement sensors to form pressure sensors that output an electrical quantity, sometimes also acting as isolation elements. The response speed of the bellows is slower than that of the bourdon tube because of the large volume change required for the expansion of the bellows. The bellows is adapted to measure low pressure.

The corrugated pipe mainly comprises a metal corrugated pipe, a corrugated expansion joint, a corrugated heat exchange pipe, a diaphragm capsule, a metal hose and the like. The metal corrugated pipe is mainly applied to the effects of compensating the thermal deformation of a pipeline, damping, absorbing the settlement deformation of the pipeline and the like, and is widely applied to the industries of petrifaction, instruments, aerospace, chemical industry, electric power, cement, metallurgy and the like. The corrugated pipe made of other materials such as plastics has irreplaceable effects in the fields of medium conveying, electric power threading, machine tools, household appliances and the like.

Corrugated pipe: a load cell in a pressure measuring instrument. It is a cylindrical thin-walled corrugated shell with a plurality of transverse corrugations, and the corrugated tube has elasticity and can generate displacement under the action of pressure, axial force, transverse force or bending moment. The corrugated pipe has wide application in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thin pipe wall and high sensitivity, and the measurement range is from tens of Pa to tens of MPa. In addition, the bellows may also serve as a sealing and isolating element, separating the two media or preventing harmful fluids from entering the measurement portion of the device. It can also be used as a compensation element to compensate for temperature errors of the instrument by virtue of its volumetric variability. Sometimes also as a resilient coupling joint or the like of the two parts. The corrugated pipe can be divided into a metal corrugated pipe and a nonmetal corrugated pipe according to the forming materials; it can be divided into single layer and multilayer according to structure. Single-layer corrugated pipes are used more often. The multilayer corrugated pipe has high strength, good durability and small stress, and is used in important measurement. The material of the bellows is typically bronze, brass, stainless steel, monel, inconel, and the like.

The corrugated pipe sometimes needs to be processed before being used, the pipe body of the corrugated pipe is small, and the corrugated pipe is not convenient to process due to the fact that the surface of the corrugated pipe is provided with the corrugations, so that the corrugated pipe needs to be fixed before being processed and then processed.
