Description

Technical Field

[0001] The utility model relates to a mechanism for assisting the feeding and unloading of a gas expansion shaft of an aluminum coil slitting machine. Background Art

[0002] Aluminum coils are generally divided into hot-rolled coils and cast-rolled coils. Aluminum strips are formed into aluminum coils by winding them layer by layer on the coiler of a hot-rolling or cast-rolling mill. Then, when unloading the coil, the steel sleeve and the aluminum coil are unloaded together and transported to the cold rolling mill for production. The coiler and uncoiler of the rolling mill both have an air expansion shaft. When the sleeve is installed, the air expansion shaft contracts, that is, when the diameter is reduced, the outer diameter of the expansion shaft is smaller than the inner diameter of the sleeve, which is convenient for installing the sleeve. When the diameter of the air expansion shaft is expanded, the outer diameter is larger than the inner diameter of the sleeve, which is conducive to fixing the aluminum coil on the air expansion shaft. The steel sleeve mainly plays a role in bearing and fixing the aluminum coil. The aluminum coil is wound on the steel sleeve, and the steel sleeve is in direct contact with the uncoiler and coiler air expansion shaft, and the coiling and unloading operations are completed by the expansion and contraction of the air expansion shaft.

[0003] After completing the operation, the traditional slitting machine opens the two rubber rollers supporting the aluminum coil, allowing the air-expanding shaft to fall into the groove of the discharge arm, and then controls the cone head shaft to detach from the grooves at both ends of the air-expanding shaft through the oil cylinder. However, due to the excessive weight of the aluminum coil and the friction between the air-expanding shaft and the inner wall of the groove of the discharge arm during the coiling process, the discharge arm is deformed and the inner diameter of the groove becomes larger. When the air-expanding shaft falls into the groove in the discharge arm, the actual height of the air-expanding shaft will be lower than the predetermined height, resulting in the cone head shaft and the air-expanding shaft being unable to detach. Therefore, an auxiliary mechanism is needed to compensate for the height difference caused by the deformation of the discharge arm. Utility Model Content
