Leveling machine

Abstract

The invention discloses a planisher, belonging to the molding technique, which can apply the belt steel planisher and the cold rolling finisher. It comprises an automatic thickness control cylinder and a table servo valve; wherein, the hydraulic elements as servo valve and the accumulator are mounted beside the automatic thickness control cylinder; the storing bracket of working roller beside the transmission is mounted on the base via bolt; the bolt and stop cut inside the framework used to change rolling rails are mounted on the bend roller; the roller changing vehicle of working roller besides operation is moiunted on the rail of roller changing vehicle of base. The invention can improve the response frequency of servo control system, simplify the design, and improve the service life with easy maintenance, short time for changing roller when the belt steel is between two working rollers, and improved working efficiency of planisher.

Description

technical field [0001] The invention belongs to the technical field of forming, and discloses a tempering machine, which is especially suitable for strip steel tempering machines and cold rolling mills. Background technique [0002] The main function of the tempering machine is to improve the shape of the steel plate and eliminate the local thickness tolerance, so that the steel plate has a good shape and better surface quality; in addition, the use of a small reduction can also eliminate the yield platform, Improve the deep drawing performance of steel plate. At present, most of the tempering machines are imported, and some automatic thickness control cylinders are push-up structures placed at the lower part of the archway window. The working environment of automatic thickness control cylinders, servo valves and their hydraulic components is poor, and they are affected by dirt such as iron oxide scale. Erosion affects service life; Servo valves, accumulators and other hydr...

Problems solved by technology

At present, most of the tempering machines are imported, and some automatic thickness control cylinders are push-up structures placed at the lower part of the archway window. The working environment of automatic thickness control cylinders, servo valves and their hydraulic components is poor, and they are affected by dirt such as iron oxide scale. Erosion affects service life; Servo valves, accumulators and other hydraulic components are connected to long pipelines, which affects the response frequency of the servo control system; it is inconvenient for spot inspection workers to observe, and maintenance is inconvenient; some roll changes require lateral movement of work rolls Mechanical, unable to achieve fast roll change online (strip steel in two working rolls); high equipment investment and high maintenance costs
