Description
Technical Field
[0001] The utility model relates to the technical field of hot coil boxes, and specifically provides a cylinder head structure of an oil cylinder. Background Art
[0002] Since the hot coils in the hot coil box are coil-free coils, the coil core needs to be fully opened at the tail of the coil, otherwise the tail will be folded. When there are a few turns of the coil left, the coiling pin is inserted into the inner ring of the coil to ensure that the tail of the coil is opened. The coiling pin is to prevent the tail of the coil from entering the head shear and finishing mill before it is fully opened. The coiling pin consists of a pin head, a bearing mechanism, a connecting rod, a cylinder head connector, a cylinder, etc. The cylinder head connector is the middle part connecting the connecting rod and the cylinder. During use, the connecting rod thread or the cylinder thread often The loose situation makes it impossible to reset the uncoiling pin, and the next steel coil in the hot coil box cannot be uncoiled and the coil core cannot open the scrap steel. At the same time, it is necessary to twist the cylinder piston rod to make a threaded connection and replace the cylinder. Since the cylinder is installed in the guide groove, there is no space to twist after the tool is inserted. It takes a lot of time to tighten the piston rod and replace the cylinder. Once the thread is slipped, the connection will completely fail, and a series of equipment such as the cylinder head connector, connecting rod, bearing, etc. need to be replaced, which is time-consuming and laborious.
[0003] Accordingly, the art requires a new oil cylinder head structure to solve the above technical problems. Utility Model Content
