Description

Technical Field

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

[0002] Metal bellows is a pipe with a regular wave-like appearance. Commonly used metal bellows are carbon steel and stainless steel, as well as steel lined with plastic and aluminum. They are mainly used for non-concentric axial transmission with a very small bending radius, or for connecting pipes and equipment. In the processing of metal bellows, cutting devices are often used to cut the bellows. In order to facilitate the cutting of metal bellows, specific cutting devices are used to cut the metal bellows.

[0003] In the cutting device, the two ends of the cutting part of the metal bellows are limited by the clamping device, and the cutting device cuts the metal bellows at the clamping part inside the clamping device at the same time. However, the metal bellows is wavy, and the metal bellows is in a convex and concave state, and has a bending characteristic. When the cutting device contacts and cuts the metal bellows, the cutting device applies pressure to the metal bellows, and the pressure causes the metal bellows to deform. When the metal bellows is deformed, it causes deviations in the cutting part, which in turn affects the cutting quality of the metal bellows. For this reason, we propose a cutting device for metal bellows processing. Utility Model Content

At the same time, the inner support plate can extrude and limit the metal bellows from the inside. At the same time, when cutting the metal bellows, it can prevent the metal bellows from sinking inward, causing the cutting part to be offset, thereby solving the problems raised in the above-mentioned background technology.
