The technical scheme of the utility model is as follows:
the utility model provides a hot rolling round steel head saw cuts and lifts device, the device sets up between saw export and roll table, it contains pivot, connecting rod, pneumatic cylinder base, support, roller and backup pad, roller and pivot are at coplanar and parallel arrangement with the roll table, roller both ends are equipped with bearing and bearing frame, be equipped with in the pivot with roller and hot rolling round steel head matched with backup pad, the pneumatic cylinder body articulates on the pneumatic cylinder base, the pneumatic cylinder jar pole passes through the connecting rod and is connected with the pivot drive, the pivot both ends rotate respectively and are connected on the support.
One end of the connecting rod is connected with the rotating shaft through a key slot, and the other end of the connecting rod is connected with the cylinder rod of the hydraulic cylinder.
The support is internally provided with a copper sleeve matched with the rotating shaft.
The copper bush matched with the rotating shaft in the support is provided with an oil groove, and the support is provided with an oil filling hole communicated with the oil groove.
The supporting plate on the rotating shaft, which is matched with the roller and the head of the hot-rolled round steel, is a rectangular steel plate.
The rectangular steel plate is fixed on the rotating shaft.
By adopting the utility model, when the round steel head is sawed, the supporting plate is lifted to support the round steel head, so that the round steel is prevented from being in a 'low head' state when being cut, and the sawing end surface is smooth.
The beneficial effects of the utility model are as follows: when the head defect is sawed by the sawing machine, the head cannot be lapped downwards, so that the end face of sawing is smooth, the sawing quality is ensured, and the manual secondary treatment is reduced.
