Description

Technical Field

[0001] The utility model relates to the technical field of grinding, and more specifically, to a grinding device for the end surface of a corrugated pipe. Background Art

[0002] The bellows is a cylindrical thin-walled corrugated shell with multiple transverse corrugations, usually made of metal (such as stainless steel, carbon steel) or plastic, with good elasticity. It is widely used in instrumentation, medical equipment, automotive industry, packaging materials and construction.

[0003] The existing bellows grinding device does have some obvious drawbacks in design and use, which greatly affect the grinding effect and the safety of operation. First, the clamping function of the device is not satisfactory and the bellows cannot be firmly fixed. During the grinding process, due to unstable clamping, the bellows is easily affected by external forces, resulting in tilting or popping out. This will not only seriously affect the accuracy and effect of grinding, but also may cause problems such as unevenness or scratches on the surface of the bellows. Secondly, when the bellows tilts or pops out during the grinding process, its sharp edges may directly injure the staff, bringing great safety hazards to the operation process. This not only increases the risk of industrial accidents, but also may affect production progress and efficiency. In addition, the existing bellows grinding device usually lacks adjustment function and cannot adapt to the grinding needs of different angles. This means that the device can only grind a fixed angle of the end face of the bellows, but cannot achieve multi-angle or all-round grinding. This limitation greatly reduces the practicality and flexibility of the device, requiring operators to frequently change equipment or adjust angles when handling bellows of different shapes and sizes, increasing the complexity and difficulty of operation.
