Structure description:
Cold Shear in rolling mill is mainly composed of main motor, belt pulley, flywheel, pneumatic clutch brake, reducer, crankshaft, cutter shear mechanism, frame body, press device, tool change device, hydraulic control system, lubrication system, electronic control system. The connecting rod that drives the shear mechanism to move up and down is installed in the eccentric position of the crankshaft. Both sides of the eccentric position are provided with copper bushings to support the crankshaft.
1) Belt driving device: the main motor transmits the motion to the flywheel through the triangle belt (the flywheel is connected with the passive belt wheel).
2) Pneumatic pressure clutch, brake and reducer: When the clutch is closed, the flywheel transmits the movement to the reducer; When the clutch is open, the braking function will be realized, the reducer will stop working, and the flywheel will idle.
3) Crankshaft and shear device: The crankshaft is mounted on the frame body, the crank tool holder is mounted on the crankshaft, and the tool holder moves up and down in the slide way of the frame body. When the clutch is closed, the reducer works, turning the crankshaft to rotate. The crank tool holder moves down quickly from the high position to achieve shearing (the blade is installed on the tool holder through the tool holder). When the shearing is complete, the clutch opens and the crankshaft tool moves upward as the crankshaft turns. When it moved to high place, the brake immediately works. At this point, the crankshaft stops running, waiting for the next loop to work.
4) The frame body and tool rest are portal frame structures of cast welding. The crankshaft is mounted in a copper alloy sleeve on the frame body. The tool rest is installed in the slide way of the frame body. The slide is made of copper alloy liner and mounted on the slide. The inclined slide board can adjust the gap between the tool rest and the slide. The normal gap is 0.2mm to 0.3mm.
5) The locking of the cutter seat adopts the disc spring locking and hydraulic opening. When replacing the cutterbed, push it from the hydraulic cylinder to the cutterbed replacement trolley or pull it from the cutterbed replacement trolley into the shear.
6) The material clamping device is composed of a material clamping head, a lever and a cylinder. Its function is to press the head of the bar tightly to prevent the beating during shearing.
7) Lubrication system: The copper slide plate and the copper bushing of the shearing mechanism are lubricated with grease, and the gear and bearing of the reducer are lubricated with thin oil.
8) Electrical control system: The electronic control system consists of a control cabinet and an operation table. The main motor is frequency sensitive rheostat. Each control point and process control is completed by a Siemens S7-200 programmable controller. Low voltage components are Schneider products.
