1. Main usage
The WYQ24-16 is a semi-hydraulic, 3-roller type profile bending machine designed primarily for bending various steel profiles. It can roll “O” spiral-shaped workpieces and is widely used in industries such as petrol, chemical, shipyard, metalworking, and machine manufacturing.
2. Technical Parameters
Here are the technical specifications:
To choose the appropriate model, refer to the maximum bending resistant modulus of the profiles.
3. The main structure of the profile bending machine
All three rollers serve as the main drive roller. The top roller moves by elevation, while the bottom roller rotates in a fixed position. It is easy to remove the finished workpiece, and the machine features an independent and movable console to facilitate operation.
This advanced machine is easy to operate and maintain, and has a small flat edge. The top roller is installed above the machine body, and the sides of the top roller are supported by cylindrical roller bearings.
The top roller is driven by hydraulic power and can move up and down, while the bottom roller remains stationary. Both the top and bottom roller shafts are main drive shafts, which are driven by hydraulic motors, gears, and chains.
The synchronous mechanism is uniquely designed to ensure that the top and bottom molds have the same line speed when bending different profiles. Additionally, the guide roller is designed to facilitate the rolling of asymmetrical sections and prevent bending defaults.
4. Hydraulic system
The hydraulic system is used to drive the motor, which in turn rotates the top and bottom rollers, and also to drive the cylinder to move the top roller up and down.
The design of the hydraulic system is reasonable and it operates reliably. It is equipped with a high-accuracy oil and return oil filter to ensure the cleanliness of the system oil. The main valve of the hydraulic system uses high-quality, well-known products.
The pump, oil filter, motor, and seals are all made by reputable domestic or foreign joint-venture manufacturers, and their advanced performance and reliable quality are assured.
All hydraulic parts in the factory undergo rigorous testing and screening to eliminate any hidden problems. The pipeline system is laid out for convenient operation, flexible action, and equipped with overload protection devices.
5. Electric system
- Main voltage 380V 50HZ 3phases
- Main motor 5.5KW
The electric control part of the machine functions as the core, which comprises the electric control system and hydraulic system to facilitate every machine action. The main buttons, move button box, and console constitute the primary control panel.
The digital display exhibits the amount of movement, ensuring a convenient and intuitive operation.
The high voltage components of the main electrical system are of branded and high-quality products, boasting of a long service life and no downtime due to faults.
6. Main characteristic
6-1. The molds of this machine exhibit excellent mechanical properties, high strength, and strong wear resistance, making them suitable for high load operations with a long lifespan, thanks to forging, quenching, and tempering.
6-2. The end of the main shaft features a double-row, self-aligning roller bearing with a large capacity that reduces power loss caused by friction, thereby offering a long service life and energy efficiency.
6-3. The movable console and digital display for the top roller elevation amount make the operation of this machine easier.
6-4. The top roller elevation is monitored by a high-accuracy displacement sensor to ensure precision for each roller.
6-5. This machine has a strong, rigid whole-body design that provides good hoisting and easy installation. The annealing treatment eliminates stress, improves accuracy, and makes it suitable for use.
7. Profile bending machinery installation and commissioning
The ground plane level and tilt in any direction shall not exceed 2mm/m.
Machines must be fully checked before installation. Only after all preparations are completed, can the installation proceed in sequence.
The mold surface level serves as a benchmark for checking the tilt and upper and lower mold parallelism. Adjustments should be made to meet the requirements.
Before tightening bolts, ensure that all installations are inspected.
The equipment must be able to run flexibly after installation.
Before starting the test, ensure that the connections are secure and inspect and adjust the gaps in all moving parts and travel to verify that the electrical switch is working properly.
After completing the preparatory work for commissioning, conduct a 10-minute commissioning and then stop to check if everything is in good condition before proceeding with the load test.
8. Profile rolling machine operation and safety maintenance
This equipment is both easy to operate and reliable. Simply push the “forward” and “backward” buttons separately to achieve different rotation directions. The following principles should be followed during operation:
8-1. Do not operate the machine when the electrical system is abnormal.
8-2. Only operators who are familiar with the machine and adhere to the rules should be allowed to operate it.
8-3. Ensure that the working area is well lit.
8-4. Do not allow the two sides of the workpiece to overlap, as this may cause damage to the machine.
To ensure the machine runs smoothly, it is important to replace worn parts in a timely manner. Additionally, it is recommended to establish a reasonable repair and maintenance system, and keep the workplace and device surroundings clean and tidy.
9. Machine lubrication
Proper machine lubrication is crucial for reducing power consumption and increasing the machine’s lifespan. To achieve this, it’s essential to choose the right lubricants and establish the necessary lubrication system.
9-1. Lubrication: The machine should be lubricated with oils that are suitable for its specific application. There are three main ways to deliver lubricant to the machine: lubricating oils, artificial fuel, and lubricating oil tanks.
9-2. Lubricant Selection: When it comes to selecting the appropriate lubricant, the artificial refueling department should use calcium-based grease. For oil cup lubrication points, calcium-based #2 grease is recommended for use in the summer, while # calcium-based grease is preferred for use in the winter.
9-3. Lubrication System and Notes: It’s essential for the user to establish a specific lubrication system based on the machine’s workload and operation. Before starting the machine, lubrication points must have sufficient oil supply. In continuous working conditions, oil cup oil should be lubricated every 4 hours, and the gears should be lubricated once a month. The entire lubrication system should be washed once a year.
