How to operate the plate rolling machine more safely under high temperature?

The plate rolling machine is a type of plate rolling machine used in many large, medium and small manufacturing plants. It makes the production of the factory more efficient. The quality of the rolling machine sold now is also good. Of course, during its use, the coiling machine should pay attention to the correct way and method of use. The operator should understand the operating procedures of the coiling machine in detail, and the rules of use, and should not operate blindly without any training. Otherwise, it is likely to bring a lot of problems and troubles, reduce the efficiency of the production work such as coils, delay the production process more time, and cause certain losses.

For the bending plate machine, analyze its processing function and cost resistance, guess the service life, and change the tool in time if necessary. For the majority of customers, the important guarantee of the rolling machine is the quality of the rolling machine. However, the word quality includes many aspects, such as the efficiency of machinery and the production technology of the bending machine itself.

In the past, most plate rolling machines used magnetic powder clutches to control tension, but the speed of magnetic powder clutches could not be high, which would easily cause high-speed friction of magnetic powder during operation, resulting in high temperature, shortening its life, and in severe cases, it would jam and hinder the operation of the machine. With the development of science and technology, a new generation of plate rolling machines occupy the market. It uses servo drive technology, vector frequency conversion motor to control the tension system of the plate bending machine, automatic detection by the swing roller, intuitive man-machine interface, more stable and reliable tension system, and easy operation. The new generation of equipment also uses advanced technology from the United Kingdom. The light-touch computer interface control makes the operation easy and the perfect roll paper force setting program can be directly controlled on the man-machine interface.

The operator of the coiling machine should tidy up the working environment and maintain a good operating environment before operating. At the same time, the operator must be dressed neatly to avoid getting caught in the roll at the corner of the work. During the process, it must be noted that the operator can only stand on both sides of the workpiece is a reasonable position. Only when the operator is familiar with and mastered the operation and use of the plate bending machine, can the efficiency of the use and work of the plate bending machine be guaranteed, and the personal safety of the production operators can be guaranteed, thereby reducing the cost required for production and improving the economic benefits of production. 

Metal Bending Machine

How to do the maintenance work of the rolling machine?

The plate rolling machine is general equipment for rolling metal sheets into cylindrical, arc, or other shapes. The working capacity of the plate rolling machine refers to the ability of the plate to roll the maximum plate thickness and width according to the specified yield limit in the cold state.

The movement form of the metal fabrication equipment can be divided into two forms of movement: main movement and auxiliary movement. The main motion refers to the rotation, bending, and other motions of the upper and lower rollers forming the plate bending machine to process the plate. The main motion completes the processing tasks of the plate bending machine. Auxiliary movement is the movement of the rolling machine in the form of loading, unloading, lifting, tilting, and turning of the inverted head frame during the rolling process.


The use of rolling machine equipment is not only related to the quality of the product but also has a lot to do with daily maintenance. If employees conduct regular inspections and repairs on the equipment in daily production, they can prevent problems and learn more about related issues. The knowledge can respond to emergencies.

Let's talk about the regular maintenance of the rolling machine:

1. Add oil to each oil cup lubrication and manual lubrication points as required.

2. Roll the plate according to the parameters of the plate rolling machine rules, and can not exceed its limit.

3. After turning on the power, carry out the movement of the lower roller in both positive and negative directions and the lifting movement of the upper roller to check whether each movement is abnormally stuck.

4. Strictly operate in accordance with the rolling processing procedures and operating methods. When the upper roller is lifted to the limit position, pay great attention to the safe operation of the equipment.

5. All personnel must reconcile with each other during operation, follow the instructions of the person in charge of the rolling plate, and prevent the machine from being operated without a password.

6. Pay great attention to safety when performing plate rolling operations to prevent your hands from being pressed by the steel plate and being rolled in with the steel plate.

7. When the main drive is stopped, the upper roller can be lifted and lowered, the overturned bearing can be tilted and reset, and the upper roller can be tilted.

8. In the course of operation, if irregular noise, impact, and other abnormal phenomena are found, the machine should be shut down immediately for an inspection.

9. When lifting the steel plate or drum with a crane, be careful not to bump into the machine.

10. After the coiling operation is completed, the place where all the materials are completed should be cleared, and the power supply should be closed in time.

What problems should occur in the operation should be shut down immediately?

1. The temperature rise of the bearing seat of the plate rolling machine is too high.

2. The plate rolling machine emits white smoke.

3. Severe vibration occurs.

4. The noise increases suddenly or abnormal noise occurs.

What types of rolling machines are there?

Because of the different fields of use, the types of bending machines are also different. From the number of rolls, it is divided into three-roller and four-roller. The 3 roll bending machine is divided into the symmetrical three-roller bending machine, horizontal downward-adjusting three-roller bending machine, arc-downward-adjusting plate bending machine, upper-roller universal three-roller bending machine, and hydraulic CNC bending machine. From the transmission point of the mechanical type and hydraulic type. In terms of the development of plate bending machines, the upper roll universal type is the most backward, the arc downward adjustment type is slightly advanced, and the horizontal downward adjustment type is the most advanced.

The three-roller bending machine has 1, mechanical type and 2, hydraulic type

1. The mechanical three-roller bending machine is divided into symmetrical and asymmetrical.

Mechanical three-roller symmetry

Performance characteristics of mechanical three-roller symmetrical plate bending machine: The structure of the machine is three-roller symmetrical. Rotational motion, through the output gear of the reducer meshing with the lower roller gear, provides torque for the rolled plate. The disadvantage of this machine is that the end of the plate needs to be pre-bent with the help of other equipment.

Mechanical three-roll asymmetrical

The main features of the mechanical three-roll asymmetrical plate bending machine: the structure of the machine is a three-roll asymmetrical type, the upper roller is mainly driven, and the lower roller moves vertically to clamp the plate and mesh with the upper roller gear through the lower roller gear, At the same time as the main drive; the side rollers are tilted and lifted, with the dual functions of pre-bending and rounding. Compact structure, convenient operation, and maintenance.

2. Hydraulic type

The main features of the hydraulic three-roller symmetrical plate bending machine: The upper roller can be vertically lifted, and the vertical lifting hydraulic transmission is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod; the lower roller is driven by rotation, and the output gear of the reducer meshes. Provide torque for the coil, and there is a supporting roller under the lower roller, which can be adjusted. The upper roller is in the shape of a drum, which improves the straightness of the product and is suitable for ultra-long tanks with various cross-sectional shapes.

It is an upward-adjusting symmetrical three-roller plate rolling machine, which can roll metal sheets into circular, arc-shaped, and conical workpieces within a certain range. The two lower rollers of this model are the driving rollers and the upper roller is the driven roller. It is widely used in shipbuilding, boiler, aviation, hydropower, chemical, metal structure, and machinery manufacturing industries.

It is suitable for bending and deformation of metal plates. It can roll around, arc, and tapered workpieces within a certain range, and has the function of pre-bending the end of the plate. The two lower rollers of this model are active rollers that can move horizontally. The roller is a driven roller that can move up and down. There are mechanical and hydraulic movement modes. The driveshafts are all connected by universal couplings.
