Quick decomposing roll changing rolling mill

Abstract

The invention relates to a rolling mill capable of rapidly split-type changing rollers, which is characterized in that independent upper and lower crossbeams and two pillar parts are arranged on a pedestal and are embedded-type matched and connected with each other to form a split-type combined frame; a supporting roller bearing device is arranged on the top of the pillars; an upper and a lower roller lifting adjusting devices are arranged in the upper and the lower crossbeams; the upper crossbeam is connected with an upper slider through a connector; a power-driven pillar upward opening device is arranged on the top of the pillars; a power-driven pillar downward opening device is arranged on the pedestal; chutes are formed on the opposite side surfaces of the two pillars and are formed on the side surfaces of the upper and the lower sliders corresponding thereto; a door frame capable of sliding along the chutes is arranged in the chutes; and a door frame travel mechanism is arranged on the bottom of the door frame corresponding to the bottom surface of the lower slider in a lower shaft system. The rolling mill has the advantages of reasonable design, compact structure, lowered labor intensity, shortened frame disassembly time such as roller changing time, automatic control, rapid and simple roller changing operation, safe and reliable operation, convenient maintenance, etc.

Description

technical field [0001] The invention belongs to roll mill equipment including a pipe profile rolling mill, and in particular relates to a quick split type rolling mill for changing rolls. Background technique [0002] At present, roll mills have been widely used in the metallurgical industry. In order to improve production efficiency, multiple rolling mills are often used to form a rolling mill production line; and the structure of each roll mill , The lower beam is made into an integral frame, and the lower shaft system, side rollers, side roller lifting adjustment devices, and upper shaft system are installed in the frame. In the rolling mill production line, the raw material enters from the first rolling mill, passes through several rolling or forming, and finally the finished product comes out from the last rolling mill. When the specifications are changed, the rolls are ground or repaired, the rolling mill needs to be disassembled and assembled. The length of the disas...

Problems solved by technology

It must transport the shafting including rolls and bearing housings to the roll changing area one by one, lift them out from the archway and reinstall them. Although the roll changing and maintenance work can be performed off-line, it is not easy to automate, and the labor intensity is high. longer time
