1, Equipment overview The machine belongs to hydraulic 3-roller plate rolling machine, used for processes such as pre-bending, rolling to round, round setting of all kinds of containers with carbon steel, low alloy steel feeding once and need not u-turn. Upper roller can vertically move and horizontally move. Pre-bending is realized through the upper rollers horizontal moving so that upper roller is in nonsymmetrical position relative to lower roller. Rolling circle is through the motor and speed reducer drive to take two lower rollers. The constant elevation of lower roller is convenient for operation and feeding. Provide detailed electrical schematic diagram, electrical wiring is strictly carried out according to the diagram, every number on both ends of wire is clear and complete, wire terminal strip is marked the same wire number with wire number, and marked with corresponding marks on electrical appliance wiring diagram and schematic diagram. The electrical equipments use all adopt brand quality products, electrical protection devices (such as the current relay, air switch etc.) have been tested strictly before installation and promise reliable operation. Equipment runs smoothly with flexible controlling, no resistance, no leakage and no abnormal noise. Paint surface is smooth and bright with average thickness and no defects such as flow mark leakage injection. Overturning rack adopts hydraulic overturning with fast speed. The upper rollers displacement adopts hydraulic transmission; horizontal movement adopts mechanical transmission with high speed. Equipment has high reliability and low failure rate. 2, Main specifications Plus-pressure 1600 Tons Max. plate width 3000 mm roller working length 3000 mm Max.
