Abstract
The present invention discloses a high-speed flying shear for plate and band materials for metallurgy industry, which comprises hydrodynamic lubrication and electric control systems. A main motor, a reductor, a gear box, a universal shaft and a flying shear body are orderly arranged on a machine row. A pair of shear blades doing circular motion is arranged on the flying shear body. An adjustment device for the opening degree of the shear blades, an inlet pinch roll, an outlet pinch roll and a machine frame roll are installed on a machine frame of the flying shear body. The shearing speed of the high-speed flying shear for plate and band materials of the present invention to plate and band materials is high, and the shearing speed is from a plurality of meters to scores of meters/per minute. The adjustment device for the opening degree of the shear blades realizes the section shearing of the plate and band materials in a high-speed motion process. The high-speed flying shear is only provided with a pair of shear blades which does circular motion. Shearing motion is controlled by the adjustment device for the opening degree of the shear blades. After the plate and band materials are sheared in a section mode, the inlet pinch roller of the high-speed flying shear can establish stable tension with a rolling machine at the front, and the stable tension is transmitted to the outlet pinch roll and a front pinch roll of a reeling machine. The stability of the plate and band materials in the production process is kept, and the quality of the plate and band materials is enhanced.

Described a pair of cutting edge be installed on respectively on the upper shearing drum of flying shear body frame and the lower shearing drum, by cutting edge clamping device fixing upper scissor blade and lower scissor blade.
The motor of described cutting edge opening degree adjusting device and decelerator, pinion, axle, gear eccentric bushing, bearing are installed in respectively on the flying shear body frame.
Described cutting edge clamping device is connected with baroclinic block with oil cylinder by the pull bar that spring is housed.
Described entrance pinch roll is equipped with top pinch roll and the bottom pinch roll that is connected by universal-joint spindle, bearing block by motor with outlet on the pinch roll respectively, and top pinch roll is equipped with oil cylinder.
Described breast roll is the roller that is connected by universal-joint spindle by motor.
Beneficial effect of the present invention: high-speed flying shear for plate and band material is installed on strip material continuous hot-rolling mill or the strip material cold continuous rolling production line, particularly on endless rolling of strip material or the semi-endless rolled production line, the strip material of high-speed motion is carried out crop, back-end crop, disjunction shear.High-speed flying shear shear plate window of web velocities is fast, speed from several meters of per seconds to tens meters of per seconds, cutting edge opening degree adjusting device is realized band disjunction shearing in the high-speed motion process: high-speed flying shear has only a pair of cutting edge, and cutting edge is made circular motion, and shearing motion is controlled by cutting edge opening degree adjusting device.The entrance pinch roll of high-speed flying shear can be set up stable tension with the milling train of front after the band disjunction is sheared, and stable tension is passed to pinch roll before outlet pinch roll, the coiling machine.Can realize endless rolling of strip material or semi-endless rolled production, the stability of holding plate band production process, thus improve strip material output, quality and production efficiency.The basic mechanical design feature of state's tyre steel high-speed flying shear and the technology of the present invention sees Table 1.
