Description

Technical Field

[0001] The utility model relates to the technical field of rubber O-ring production and processing equipment, in particular to a rubber O-ring cutting device. Background Art

[0002] Rubber O-rings are devices used to seal pistons in reciprocating hydraulic cylinders. They are made of polyurethane TPU, CPU, and rubber. They have excellent sealing properties and a long service life. When producing rubber O-rings, a cutting device is used to cut an O-shape on a rubber sheet to make a rubber O-ring.

[0003] In the prior art, after the O-ring is cut out on the rubber sheet using a cutting device, the cutter is reset, and then the operator manually moves the rubber sheet to move the uncut portion to just below the cutter for cutting again. However, it is not easy to control the moving distance of the rubber sheet manually, and it is easy to move the distance too close or too far. If the distance is too close, the position where the cutter cut last time will cause a gap in the cut O-ring and it cannot be used normally. If the distance is too far, it will cause waste of material. For this reason, we designed a rubber O-ring cutting device to solve the above problems. Utility Model Content
