How does the upper roller universal hydraulic rolling machine work under high load conditions? Has it been strengthened to cope with heavy workpieces?
Publish Time: 2025-02-20
The upper roller universal hydraulic rolling machine has indeed undergone a series of strengthening designs to cope with heavy workpieces under high load conditions. These strengthening measures are mainly reflected in the following aspects:
1. Structural strengthening
Roller material and process: The three rollers (upper roller, lower roller and idler) of the upper roller universal hydraulic rolling machine are solid forged rollers, and are tempered and quenched to improve their hardness and wear resistance. The roller surface may also be chrome-plated to prevent the plate from scratching and leaving marks during the rolling process.
Drum-shaped upper roller design: The upper roller is in the shape of a drum. This design helps to better distribute the pressure during the rolling process, improve the rolling accuracy and product quality. The upper roller drum preset is generally preset to 70% of the uniformly distributed load of the roller to meet the rolling requirements under different load conditions.
Idler roller matching adjustment: There is a roller matching adjustment at the bottom of the lower roller. The height of the idler can be adjusted according to the load of the rolled product to adapt to the rolling of plates of different thicknesses. This design helps to improve the straightness and roundness of the product.
2. Hydraulic system enhancement
Hydraulic system upgrade: The upper roller universal hydraulic rolling machine under high load conditions is equipped with a more powerful hydraulic system to ensure sufficient pressure and flow to meet the needs of rolling heavy workpieces. The hydraulic system may use a high-performance gear pump or axial piston pump to improve the stability and durability of the system.
Solenoid reversing valve and limit switch: The hydraulic system uses an electromagnetic reversing valve to control the movement direction of the cylinder to ensure the precise operation of the plate rolling machine. The setting of the limit switch can ensure that the cylinder stops moving in time when it reaches the predetermined position to prevent overload or damage.
3. Control system enhancement
PLC programmable display control: The upper roller universal hydraulic rolling machine is equipped with a PLC programmable display control system, and the digital operation is simple and easy to learn. The PLC system can monitor the operating status of the machine in real time and adjust and optimize it as needed.
Displacement sensor and feedback system: The setting of the displacement sensor can monitor the position and movement status of the upper roller in real time. The feedback system can ensure the synchronization and precision control of the upper roller during the rolling process and reduce the amount of product misalignment.
4. Safety Enhancement
Safety protection measures: The upper roller universal hydraulic rolling machine is designed with full consideration of the safety of operators. For example, the two lower rollers are fixed, the upper roller moves up and down, left and right, and the workpiece does not move with the working roller, reducing the safety risks during operation. At the same time, the machine may also be equipped with an emergency stop button and other safety protection devices.
Operation specifications and training: Operators need to receive professional training before using the upper roller universal hydraulic rolling machine to understand the performance, operation methods and safety precautions of the machine. Strict compliance with the operating specifications can ensure the stable operation of the machine under high load conditions and the safety of the operator.
In summary, the upper roller universal hydraulic rolling machine copes with heavy workpieces under high load conditions through structural reinforcement, hydraulic system reinforcement, control system reinforcement and safety reinforcement. These reinforcement measures ensure the stable operation of the machine, high-precision rolling and the safety of the operator.
