Bow beam bender machine Shu Shu 250 camber machine

 250-automatic electro-hydraulic control type bending machine (cold-formed arch machine) is my company developed a new type of automatic steel camber machine. Hydraulic system, with a smooth transmission, pressure and other characteristics, mainly used in curved tunnel, subway, station, underground caverns and other beams, channels, such as U-shaped steel angle profiles. 250-automatic electro-hydraulic bending machine is controlled steel arch tunnel support manufacture of new equipment. It consists of a base, mechanical transmission, cold system, hydraulic system, electrical control systems and auxiliary systems, such as six major components. When the work required by the auxiliary cold-formed steel processing systems push door bracket on the initiative between the two rollers, the hydraulic cylinder hydraulic system start pushing the wheel dovetail slot and cold cold-formed steel, the design needed to be reached radian closed hydraulic system, start mechanical transmission, so take the initiative and rely on the friction drive wheel to rotate slowly forward smooth steel, cold-formed in order to achieve continuous operation. At the end of cold-formed, closed mechanical drive, and start the hydraulic system, the hydraulic cylinder retracted. The cold-formed steel is placed on the secondary system to door bracket. This cold bending operations to ensure the material's strength, improve the quality of steel arch support, which greatly improves the efficiency, simple and clear. Compared with the press bending machine, with good performance.

The device reasonable structure, convenient operation, strong carrying capacity, speed and volume Park, a small size, low power consumption, high efficiency, no noise, long life, a machine and many other advantages. It replaced under the original steel material, docking, correction, lathes and other complex processes, and saves oxygen, acetylene, labor, raw materials, is a high quality rolled rings and flanges, high efficiency Rolling equipment. The device can be widely used in fans, petrochemical, shipbuilding, bridge template, grid, steel buildings, large pipes, hydraulic instrumentation and other industries. Also suitable for external processing, lucrative 3. structure and working principle of the device by the main motor, reducer, rollers, pump motor, gear pumps, relief valve, solenoid valve, working cylinder, top round and tanks and other components, refer to the electrical schematics and hydraulic schematics. How it works: The I-beam on the bending machine, and reducer drive wheel after contact, will compress the feed locking handle, start the motor pump set, electric pump output from the high-pressure oil through the relief valve (adjustable required pressure), entered together into the electro-hydraulic valve block with electro-hydraulic valves and jog switch (point forward, point back) control cylinders work, work to promote the fuel tank, the I-beam and three support rollers are not pressed bending deformation occurs at the beginning of the calculation, the length of the process for each cylinder and then propelled 10mm-15mm, open the main motor forward or reverse, driven by the main motor beam work, repeated operations to achieve the desired date. 4. Use the installation instructions on a hard base surface, alignment, to feed the rail surface in a horizontal position prevail. Beam must operate at the level of the bench (with scroll table). Must refuel before use (reducer plus 30 # engine oil, hydraulic oil tank with # 46), after the regular replacement of new oil. 5. In order to ensure the smooth test machine before starting the second set put the machine to work good debugging. Check the power supply is normal. Check the motor pump set is forward. The pressure gauge switch is on, the regulator relief valve hand wheel release. Jog motor, check the direction of rotation is correct. Check the electro-hydraulic valve and jog switch is normal. All preparatory work is correct, start the motor, the hydraulic raised 10Mpa, commissioning three minutes or so, if functioning properly, prepare a formal job. 6. Cautions use the equipment properly and conscientiously perform equipment maintenance, compliance with safety procedures, reduce equipment failures, extend equipment life, safeguard the necessary conditions for safe production, and therefore equipment operator and maintenance personnel must understand the structure of equipment, performance , maintenance methods and procedures. No oil in the tank before injecting Never start the motor. Before using the first check whether the oil tank fill, such as inadequate should be filled to prevent pump cavitation. Hydraulic oil equipment used must be rigorously filtered before injection tank, the tank must be cleaned before loading oil well is generally recommended to use 46 anti-wear hydraulic oil is oil as the medium of this equipment, must be prepared to clean the oil and the equipment maintenance work, in order to avoid blockage or leakage affect the results. Fluid must be kept clean, the first time should not use more than two months, the replacement, should also clean the filter and tank, pay attention to the filter can be placed flush kerosene, can not scrub with a stiff brush, such as the oil is not deterioration, after filtration can be used. Always check whether the device is intended for the lubrication of the clogging. After the class work, please recover the cylinder. If the long-term is not used, they have to slide at the surface coated with anti-rust oil.
