Description

Technical Field

[0001] The utility model relates to the field of cutting devices, in particular to a double-station sealing ring cutting device. Background Art

[0002] A sealing ring is a device used to prevent the leakage of liquids or gases, usually made of rubber, silica gel or other elastic materials. They are widely used in various machinery, pipelines and equipment to ensure the sealing of the connection parts. The sealing ring can help prevent external pollutants from entering the equipment while maintaining the stability of the internal fluid or gas.

[0003] A Chinese patent with the authorization announcement number CN219054540U discloses a cutting device for the production of rubber sealing rings. The utility model includes a counterweight disk engraved with diameter scales, a cylindrical ring cutter, and an electric push rod. Above the counterweight disk, there is a variable-diameter cylinder with adjustable diameter, which is used for the rubber ring to be sleeved on its outer wall. On the side of the counterweight disk, there is a support frame for installing the electric push rod. By engraving diameter scales on the counterweight disk and making the diameter of the variable-diameter cylinder change accordingly, when cutting the rubber ring, the rubber ring is sleeved outside the variable-diameter cylinder, and then the variable-diameter cylinder is driven to stop when it reaches the inner diameter of the rubber ring. Then, the electric rod is driven to extend to drive the cylindrical ring cutter to cut. At this time, the excess rubber at the outer edge of the rubber ring will be cut off. With such a design, the outer edge of the cut is very flat, and the diameter change of the variable-diameter cylinder can adapt to rubber rings of different sizes.

[0004] However, this device still has deficiencies: when in use, the aperture size of the cutting blade cannot be adjusted, so it can only cut sealing rings of fixed sizes, which will reduce the cutting efficiency of the sealing rings to a certain extent. Content of the Utility Model
