Description

Technical Field

[0001] The utility model relates to the technical field of bellows processing, in particular to a bellows punching device. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters, and are mainly used as measuring elements of pressure measuring instruments. Bellows mainly include metal bellows, bellows expansion joints, bellows heat exchange tubes, diaphragm boxes and metal hoses. Metal bellows are mainly used to compensate for pipeline thermal deformation, shock absorption, and absorb pipeline settlement deformation. They are widely used in petrochemical, aerospace, chemical, electric power, cement, metallurgy and other industries. When processing bellows, the inner diameter of the tube body needs to be shaped by punching.

[0003] Authorization announcement number CN209223568U discloses a bellows punching device. The patented technology is provided with an air pump, a punching column, a positioning column and a semicircular fixing plate. During processing, the inner diameter reserved hole of the pre-processed bellows is inserted into the positioning column, one end of the bellows is pressed against the mounting plate, and at the same time, two semicircular fixing plates are aligned from both sides of the outer surface of the bellows to tighten the bellows, and then the bellows is further fixed by tightening the bolts on the semicircular fixing plates. After the fixing is completed, the air pump is started to extend, and the punching column is aligned with the inner diameter reserved for the bellows. The bellows is punched and the inner diameter is determined. The bellows is punched and the inner diameter is the size we need. After the punching is completed, the motor is started to rotate. Driven by the rotating shaft, the punching column starts to rotate in the inner diameter of the bellows to grind the inner diameter surface. However, in this solution, a side installation method is adopted when processing the bellows. This installation and fixing method is unstable and may cause the processing device and the bellows to fall. Not only is the efficiency low, but if the distance is too close to the operator, it is easy to cause accidental injury to the operator. Therefore, a bellows punching device is needed to improve the above problems. Utility Model Content
