Three-Roll Hydraulic Plate Rolling Bending Press Machine

Three-Roll Hydraulic Plate Rolling Bending Press Machine   Introduction The plate rolling process of a plate rolling machine is a continuous three-point bending process of the plate. According to the different rolling temperatures, it can be divided into cold rolling, hot rolling and warm rolling. It is mainly a mechanical equipment that bends metal plates of a certain thickness into cylindrical, arc-shaped, rectangular and other curvatures or variable curvatures. It is one of the essential mechanical equipment in the metallurgy, building materials, petroleum, chemical, water conservancy and power, bridge, military industry, coal, mining, shipbuilding, boiler, aviation, power transmission and transformation equipment manufacturing industries. This machine belongs to the hydraulic three-roll plate bending machine, which is used to complete the pre-bending, rolling and straightening of the plate ends of various container carbon steel and low alloy steel plates without turning at room temperature after one feeding. The upper roller can move vertically or horizontally. Pre-bending is achieved by the horizontal movement of the upper roller, causing it to be in an asymmetrical position relative to the lower roller. The rounding process is carried out by the motor and the reducer driving the two lower rollers. Since the elevation of the lower roller remains unchanged, it is convenient for feeding and operation. Provide a detailed electrical schematic diagram. Electrical wiring must be strictly carried out in accordance with the drawing. The numbers at both ends of each connection are clear and complete. The terminal blocks of the wires are marked with the same wire number as the connection number, and corresponding marks are made on the electrical wiring diagram and schematic diagram. All the electrical components used in the equipment are high-quality products from well-known enterprises. Electrical protection devices (such as current relays, air switches, etc.) are strictly tested before installation to ensure reliable operation. The equipment operates smoothly, with flexible control, no jamming, oil leakage or abnormal noise. The tipping frame adopts hydraulic tipping, which is relatively fast. The vertical displacement of the upper roller is driven by hydraulic power, while the horizontal movement is driven by mechanical power. The equipment has high reliability and a low failure rate.   Technical parameter No Item Unit Parameters 1 Maximum thickness of the rolled plate mm T16*B3000*φ900(0s≤245MPa) 2 Maximum pre-bent plate thickness mm T12*B3000*φ900(0s≤245MPa) 3 Maximum width of the rolled plate mm 3000 4 The working length of the roller mm 3050 5 The remaining straight side length mm ≤4 times the thickness of the board 6 Apply pressure to he upper roller T 200 7 Rolling plate speed m/min 4.5 8 Upper roller diameter mm φ330 9 Diameter of the lower roller mm Ф180 10 The center distance between the two lower rollers mm 300 11 The pressure application speed of the upper roller mm/min 120 12 Number of idlers pcs 4 13 Number of idler sets pcs 1 14 Main motor power KW 15 15 Power of hydraulic motor KW 5.5 16 Power of mobile motor KW 1.5 The equipment's capacity for rolling cone cylinders is 60% of its full-load capacity The rounding capacity is 70% of the full-load capacity Oil cooling is an optional accessory
