Rolling cut type bilateral shear mobile shear fixed width traversing device

The invention relates to a fixed-width transverse moving device of a roll-cutting dual-edge shear and movable shear applied to metallurgy mechanical industry, consists of a frame, a supporting plate, a lower sliding plate, a lower steel strip, a locking plate, a tightening plate, an adjusting wedge, a track base, a transmission screw rod, etc. The lower steel strip is arranged on the upper surface of the track base and is tightened by a tightening mechanism; a side steel strip is arranged on the side surface of the track base and is tightened by the tightening mechanism; the lower sliding plate is embedded into the supporting plate and is pressed by the pressing plate; the side sliding plate is embedded into the side supporting plate and is pressed by the pressing plate; after that, the supporting plate and the side supporting plate are butted together and wholly assembled on the track base where the steel strip is arranged; the transmission screw rod is assembled; the adjusting wedge is butted on the frame and the frame is then arranged on the assembled track base; the adjusting wedge is inserted for integrated adjustment; when technical parameter requirement is reached, the adjusting wedge is tightly locked, the supporting plate is tightly fixed on the frame, the locking plate is tightly locked and the device is finished. The device has the advantages of novel and scientific conception, convenient adjustment and disassembly, no-clearance transmission, no leakage, low manufacture cost, fast and stable adjustment and high fixed-width control precision.
