HYDRAULIC 4 ROLL BENDING MACHINE

1,Main body overview

1-1, main body overview

The machine is fully hydraulically driven, digitally controlled, with advanced structure, superior performance and high efficiency. It is at the leading level in the international and domestic industries.

Our four-roller bending machine features: 1. Side roller linear motion, increasing work stability 2. Both sides of the pressure roller use absolute encoder to control synchronization.

  This machine features:

1, full hydraulic drive, high efficiency and energy saving (drive power is equivalent to 60% of the traditional), the rolling work is safer and more reliable than other types of coiling machine.

2, permanent lubrication technology (no need to refuel during the bearing life)

3, the clamping pressure is adjustable (there is no slip, the productivity is 50%-80% higher than the three-roller bending machine), the clamping force between the upper and lower rollers on the plate can be adjusted by the hydraulic station regulating valve The required pressure corresponding to the thickness and width of the sheet when rolled.

4. The cylinder can be rolled up to 1.3 times the diameter of the upper roller. When the end of the rolled sheet is pre-bent, the length of the straight side is smaller than that of other types of coiling machines.

The main technical parameters

Hydraulic system

5-1, main body overview

The hydraulic system consists of a hydraulic pump, a valve block, and an auxiliary line piece. The hydraulic valve is selected by Yuji Oil Research Superimposed Valve System. The pipeline layout is simple, the leakage is less, and the maintenance and debugging are convenient. Each input and output port of the hydraulic system is equipped with corresponding detection points for easy maintenance and fault checking. The hydraulic station is placed on the base to reduce the space, making the foundation simple and easy to transport.

1. The system consists of three circuits, overpressure protection and pressure regulation loop, synchronous loop,

The speed loop is composed. The pressure regulation circuit regulates the system operating pressure through the main relief valve. The system working pressure is 19.5Mpa.

2. The rise and fall of the lower roller and the side roller respectively have an overflow valve for pressure limit protection.

3. In order to ensure the synchronization accuracy of the cylinder, a high-precision displacement sensor is mounted on the right frame and the overturning frame. Through the pressure sensor and the microcomputer control system, the movement and detection of the piston movement of the main cylinder are performed, and the synchronization precision of both ends of the work roll is achieved.

2, technical characteristics

1. Adopt unique pre-relief pressure technology to effectively avoid hydraulic shock and improve pipeline and seal life.

2. The hydraulic components are made of imported high quality products to ensure the stability of the hydraulic system.

3. Each input and output port of the hydraulic system is equipped with corresponding detection points, which is convenient for maintenance, fault check, oil pump adopting lower type, positive pressure oil absorption. At the same time, the filter, the liquid level gauge, and the belt sending device can automatically alarm the fault prompt. The hydraulic station is independent of the base, easy to maintain and maintain and away from the heat source.

4, the system is strictly in accordance with international and line standards, the radius of the pipe is reasonable, and not less than 90 °, the transition of the garden slip, reasonable arrangement of the shock absorber pipe clamp, effectively avoiding shock and vibration.

5, the system design fully considers high efficiency and energy saving, reduces power waste, and reduces heat sources.

6, equipped with high-precision oil absorption and return filter to ensure the cleanliness of the system oil.

7. Provide common fault phenomena and troubleshooting methods for the hydraulic system of the coiling machine.

8. In order to ensure the manufacturing quality of the hydraulic system, the system is made according to the hydraulic professional manufacturer and the national GB3766-83 "General technical conditions of hydraulic system".

9. The fuel tank is sprayed, pickled and surface cleaned, and the walls are coated with oil-resistant varnish to ensure the fuel tank is clean. There is an air filter at the fuel tank of the fuel tank to ensure the function of oil filtering and ventilation. In addition, a fine filter must be provided at the end of the oil suction pipe and the oil supply pipe.

The normal operating temperature range of the hydraulic system is 15 °C ~ 65 °C. When the temperature is less than 15 °C, it can be automatically heated by electric heater. When the temperature is higher than 65 °C, the temperature of the oil can be controlled by the cooler to make it suitable for the system work.

3. Main technical indicators of the system

      System operating voltage is 380v, 50Hz

      Ambient temperature is -15 ~ 40 ° C

      Relative humidity is &le85%
