Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical mechanical equipment, in particular to a tool for disassembling and installing a side guide plate pin shaft. Background Art

[0002] The installation of the pin in the push rod device of the side guide plate of the hot strip production line generally adopts interference fit. In the traditional pin replacement process, the pin is generally cut by destructive removal. This method has high technical requirements for the operators. If you are not careful, it will cause irreversible damage to the installation hole of the push rod, and finally affect the installation accuracy of the pin. When the pin is installed, it is usually knocked into the installation hole of the push rod. Because the pin adopts interference fit, the knocking method often causes the knocked part to deform, affecting the subsequent installation of other parts. At this time, the pin must be polished. Manual polishing not only increases labor costs and wastes time, but also the manually polished pin cannot restore the original size of the pin, resulting in deviations in the installation accuracy of subsequent copper sleeves and other workpieces.
