Hydraulic motor power(approximately)
■ The rolling machine specialized in gas-tank making industry, and it can roll carbon steel, low ally steel, etc, with normal environments around.
■ The rolling machine’s top and bottom roller drived by motor and reducer.
■ The bottom roller own fixed height, it is easy to feed the machine with material.
■ With the help of touch screen, PLC will be more easy to operate.
■ World famous parts wildly used in the machine, guarantee the rolling machine has very good performance.
■ Moving of top roller drived by hydraulic power.
▀ The rolling machine make up with bottom, left and right frame, main cylinder, top and bottom roller, movable beam device, support roller device, main gearing system, hydraulic system, electrical system, etc.
▀ The 2 bottom roller are the main fixed drive roller, the main motor drive the bottom roller by the help of main reducer.
▀ The top roller device.
;► The top roller device made up with main cylinder, top supper roller bearing, top roller bearing, top roller, swing beam and top support roller, etc.
► The 2 main cylinder provide rolling power, they working pressure is 19.5Mpa.
► The top roller with tempering processing and hardness is HB240~300.
► The top roller bearing support the top roller and combined with the swing beam on the both side of top roller, besides, the top roller support device located in the middle of top roller and swing beam.
► We use spherical roller bearing as support roller bearing, it has more long working life.
► The material of support roller is 45# steel, with tempering processing, and the hardness is HB190~220, the hardness is lower than the bottom roller, so the surface of bottom roller can be protected.
► The height of top roller can be adjusted according to operator’s requirements.
► The top swing beam is welded parts, with stress relief processing, good quality and more reliable to use.
▀ The bottom roller device.
► The bottom roller device made up with bottom roller bearing, bottom roller and bottom roller support, etc.
► The material for bottom roller is 45# steel, and after tempering process, the hardness is HB240~280.
► The bottom roller bearing support the bottom roller, and combined with bottom beam at both side of the machine. The bottom roller support located between bottom roller and bottom beam.
► The bottom roller could bearing the load from top roller when machine processing, and support roller use spherical roller bearings.
► Support roller device made up with support roller, wedge mechanism, etc.
► The material of support roller is 45# steel, with tempering process, the hardness is HB190~220, the surface hardness of support roller is lower than bottom roller.
► The bottom beam is welded part, with stress relief process.
► Main gearing device made up with main motor, reducer, brake, etc.
► Main gearing device can do positive and negative going motion, and provide torque for material rolling process.
▀ Machine frame device.
► The machine frame device made up with machine frame, bottom, and combined parts, etc.
► All machine frame are welded parts, and with stress relief process.
► 2 cylinder fixed on the machine frame.
▀ The hydraulic system made up with gear pump, value, fluid combined parts, hydraulic accessories, etc.
► We use Yuci Yuken from Japan as our machine’s hydraulic value, simple to use and easy to maintance. This device also have over-load protect system.
► The hydraulic value working pressure is 19.5MPa.
▀ Protect system.
► The process of up and down of top roller protected by fluid value.
▀ The electrical control system made up with control table, hand-hold button box, etc.
►temperature of environment, -5～45°
►relative humidity, 5%～85%
►The rolling machine use PLC control.
►The control table have all button, pilot light, programable display, etc, and can control all the rolling process.
▀ Function of rolling machine as following:
►Fault self-find system.
►Important part protect system.
►Memory function when power off suddenly.
