Description

Technical Field

[0001] This utility model relates to the technical field of maintenance tools for steel rolling equipment, and specifically to a guide pin disassembly device. Background Technology

[0002] In the steel rolling production process, the rolling guide is a key component that guides the rolled piece smoothly through the rolling mill, and its performance directly affects the quality of the steel and production efficiency. When the rolling guide reaches the end of its service life, the replacement of the pin becomes a frequent and necessary maintenance task. However, the current pin disassembly work faces many challenging problems.

[0003] On the one hand, the operation process is extremely cumbersome and time-consuming. Due to the lack of suitable specialized tools, operators often have to make their own disassembly tools. However, because the rolling guides in the rolling mill area come in a variety of models, with different pin dimensions and structures for different models, it is necessary to weld a matching tool for each model individually. This not only consumes a lot of time and materials, but also makes tool switching extremely inconvenient when changing between different models of guides, severely restricting maintenance efficiency. On the other hand, manual operation makes it difficult to accurately control the disassembly force, resulting in inconsistent disassembly tightness. This can easily cause uneven force on the tool, leading to tool breakage. In the industrial environment of rolling mill, the flying fragments from broken tools can easily injure operators, posing a significant safety hazard.

[0004] Therefore, there is an urgent need to design a guide pin disassembly device to solve the problems of the lack of suitable special tools, which makes the replacement and maintenance of the pin extremely inconvenient, seriously restricts maintenance efficiency, makes it difficult for manual operation to accurately control the disassembly force, resulting in inconsistent disassembly tightness, easily causing uneven force on the tool, and thus causing tool breakage and posing a great safety hazard.
