Metal bellowsIs a regular shape of the pipe, commonly used metal corrugated pipe carbon steel, stainless steel, steel lined plastic, metal corrugated pipe, etc., mainly used for bending radius of small non-concentric axial transmission connection, irregular rotation, expansion or absorption of pipe thermal deformation, or pipe and equipment connection.

　　Metal bellowsAs a sensitive element, damping element, compensation element, sealing element, valve core and pipe joint, it is widely used in automatic control and measuring instruments, vacuum technology, machinery industry, power industry, transportation and industry and other fields.

Metal bellows because of its use is different, choose different metal materials. Due to different materials, the performance and use of the processed metal bellows are also different.

Metal bellows expansion joints are often used as compensators. The compensator adopts metal bellows expansion joint. It has a good effect on compensating the additional stress caused by temperature difference and mechanical vibration. The product is usually installed in the shell and pipe of the container and acts as a flexible structure. Choosing a more suitable metal material to make the compensator will have a good impact on the quality. Of course, when we chooseMetal bellowsWhen expanding joints, we also need to determine them according to requirements, so that we can have good benefits in terms of reliability, and then have excellent performance in terms of quality. After all, a better product can bring more prominent advantages in use, and then a great advantage in reliability.

The automatic line will also make the surface tension of the metal bellows greater, or the calibration of the light source will not result in the same spectral response. The speed of the bellows continues to increase, the exhaust is not smooth, and the volatile content increases; the thickening effect of the material is poor and affects each other. The fluid channel under the vibration plate. For metal bellows, the high and low temperature changes rapidly to reduce the impact on the substrate. When forming the same product, it has the advantage of high repeatability of the metal bellows combination, because two batches of different pigment replacement equipment have the advantage of cleaning. However, the pressing temperature and holding time. Inserting two half-sleeves This method is particularly suitable for threaded shafts and is not suitable for direct insertion into journal parts.

　　Metal bellowsThin-walled ferrules made of medium carbon steel. Its outer diameter matches the inner ring bore of the metal bellows. During installation, sawing along the shaft with a hand saw or cutting with bellows. Cut the worn metal bellows into grooves in advance. The outer diameter of the metal bellows is the same as the inner diameter of the ferrule, and then the two halves are buckled to install the bellows. In order not to reduce the cross-sectional area of the metal bellows too much, the thickness of the two halves should not be too thick, generally 2-2.5% of the size of the metal bellows. For a shaft with a diameter of 105mm, the size of the two halves is 2mm.

Metal spraying When the journal part of the bellows is worn or the machining is out of tolerance, the journal can be metal sprayed. Before spraying, the journal part can be rotated to a certain size and then sprayed with metal. After spraying, it can be processed by lathe or grinder to meet the size requirements of the drawing. Repair worn shafts with electric welding. First, the shaft is roughly cut on the lathe, and then the shaft is welded to a certain size by manual electric welding, and then directly processed to the size required by the drawing on the machine tool.

In order to prevent bending deformation of the shaft during welding repair, the symmetrical balance anti-deformation re-welding method should be adopted. Knurling, punching, hanging tin, etc. WhenMetal bellowsWhen the journal of the is slightly worn, or the over difference during processing is small, and the matching tightness is lost, the following methods can be used to carry out temporary emergency treatment on the matching parts of the metal bellows.
