The invention discloses a main transmission shaft of a rolling mill. The main transmission shaft comprises a group of hydraulic cylinders which are arranged on supporting blocks on two sides of a spindle retainer cup, and a locking unit is respectively arranged in an upper through hole and a lower through hole in the spindle retainer cup; according to the structure of the locking unit, a nut block is fixedly installed on the junction of a flared section and a straight tube section of the through hole, a rack spring sleeve is nested in the straight tube section of the through hole, an ejector rod is arranged in an axis hole of the rack spring sleeve in a penetrating manner, one end of the ejector rod penetrates through the rack spring sleeve to face the end of a piston rod of the hydraulic cylinder, and a spring is arranged between the rack spring sleeve and an outer circumference of the ejector rod; one end of the ejector rod penetrates through the nut block, and the end, extending out of the nut block, of the ejector rod is provided with a limiting nut; the outer surfaces of the upper and lower rack spring sleeves are respectively and fixedly provided with a rack to be simultaneously engaged with a gear in a transmission manner, and the gear is connected with or separated from an intermediate roller through a clutch mechanism. By adopting the main transmission shaft, when in rolling and the intermediate roller moves transversely, the intermediate roller is reliably connected with a universal spindle in the axial direction; when the intermediate roller is replaced, an automatic unhooking device is released.
Description
technical field [0001] The invention belongs to the technical field of metallurgical equipment and relates to a main transmission shaft of a rolling mill. Background technique [0002] Ordinary six-high rolling mill adopts work roll transmission, which can realize intermediate roll traversing and positive roll bending, and work roll positive and negative roll bending. The six-high molybdenum plate reversing mill is used for cold / warm rolling single molybdenum and tungsten plates, with a maximum rolling force of 30,000KN, a maximum rolling torque of 464KN.M, and a finished product thickness of 0.3mm-4mm. Due to the small thickness of the rolling plate, the diameter of the work roll is small, and the transmission of the work roll cannot guarantee sufficient rolling torque. Therefore, in order to meet the above parameter requirements in actual work, the intermediate roll must be used for transmission. The roller must be moved laterally, which puts forward new requirements for ...
