Description

Technical Field

[0001] The utility model relates to the technical field of rubber gasket processing, in particular to an adjustable tool structure for turning rubber and plastic gaskets. Background Art

[0002] With the development of industrial technology, rubber and plastic gaskets have been widely used in numerous industries due to their excellent sealing properties. However, traditional processing methods such as die punching and automatic gasket cutting machines have certain limitations in the production and maintenance of gaskets. While die punching can ensure high processing accuracy, it requires a corresponding mold for each gasket size, resulting in high costs and unsuitable for small-batch or customized production. On the other hand, while automatic gasket cutting machines have improved production flexibility to a certain extent, they often produce rough edges when processing small-sized gaskets due to mechanical properties, affecting the gasket's sealing effect. In addition, neither method can solve the problem that gasket thickness is limited by the thickness of the sheet material.

[0003] During equipment repair and maintenance, it is often necessary to adjust the size and thickness of the gasket according to the actual condition of the equipment. This is especially true when faced with different standards for domestic or imported equipment, differences between old and new national standards, or when gaskets need to be adjusted due to rust, wear, etc. Traditional processing methods are particularly inconvenient.
