How to use the plate rolling machine rolled fast and good

Plate rolling machine to roll round is an important process that is widely used in the metal fabrication industry. Its purpose is to roll sheet metal into round shape to meet the needs of different industries. In the process of rolling round by plate rolling machine, how to realize efficient and fast operation, and at the same time to ensure the quality of rolling round, is a problem that every operator needs to pay attention to.

The basic principle of rounding of plate rolling machine is to roll the metal sheet into round shape gradually through the rollers of plate rolling machine. The coiler usually consists of upper rollers, lower rollers and side rollers. The upper and lower rollers are used to curl the metal sheet, and the side rollers are used to control the position and shape of the sheet. During the curling process of the plate rolling machine, the operator needs to adjust the position and angle of the rollers according to the specific needs to ensure the precision and quality of the curling.

1.Key tips to improve the rolling speed of plate rolling machine

（1）Choose the right rolling machine 

Different rolling machines have different rolling speeds and applicable range. In the choice of rolling machine, according to the actual needs of its rolling speed and performance indicators to ensure that it can meet the production requirements.

（2）Roller spacing adjustment 

According to the thickness of the plate and the required curvature, adjust the spacing of the rollers appropriately. Too large a distance may lead to the plate can not closely fit the rollers, affecting the pre-bending effect; too small a distance may increase the friction between the plate and the rollers, resulting in damage to the surface of the plate.

（3）Control the appropriate pressure 

In the operation of the coiler, reasonable pressure settings for the success or failure of the rounding operation is critical. Too much pressure will lead to plate deformation or rupture; too little pressure can not achieve the desired pre-bending effect. Therefore, in the operation process need to gradually adjust the pressure value according to the actual situation, until the best balance is found.

（4）Speed control

In the process of rolling round, control the operating speed of the coiler is also very critical. Too fast may lead to uneven plate deformation, affecting the final result; too slow will reduce production efficiency. Therefore, you need to adjust the operating speed according to the actual situation, in order to achieve the best productivity and product quality.

2.Rolling machine rolling process need to pay attention to the following matters

（1）Pre-treatment of the plate 

In the rolling machine before rolling round, you need to pre-treatment of metal plates, such as removing surface dirt, trimming edges and so on. This will reduce the load on the coiler and improve the speed and quality of the coiler.

（2）Regular Inspection and Maintenance 

The plate rolling machine needs regular inspection and maintenance to ensure its normal operation. The operator should regularly check the wear of the rollers and replace the badly worn rollers in time to ensure the quality of the rolled round.

（3）Straightening process 

Sometimes during the process of rolling round, slight deformation may occur, especially the lack of precision in the joint part. At this time, it is necessary to further correct through the rounding process to ensure that the roundness deviation is as small as possible, and the ellipticity is controlled within a small range. The rounding method takes time, but can ensure the accuracy of the final product.

（4） Reasonable operation 

In the rolling operation of the coiler, the operator needs to carry out meticulous operation according to the material, thickness and shape of the plate and other factors. Reasonable operation process can help us better realize the effect of rolling round without leaving straight edges. At the same time, we need to carry out regular maintenance and repair of the plate rolling machine to ensure the normal operation and service life of the equipment.

（5）Safety norms 

When the plate rolling machine is operated, it must be managed by professional personnel. Operators need to be familiar with the equipment structure and operating procedures to ensure that the safety devices are intact. During operation, it is strictly prohibited to place hands and feet near the rollers and transmission parts to avoid accidents. At the same time, regularly check the safety of the rolling machine, avoid overload work, and promptly cut off the power supply and lock the equipment after the operation is completed.

Plate rolling machine is an important metal processing equipment, the correct use of plate rolling machine can realize high-quality roll round effect. By choosing the right coiler, adjusting the position and angle of the rollers, as well as precautions, the efficient and fast operation of the coiler rolling round can be realized. Operators should continue to learn and accumulate experience to improve their own technical level and realize the high efficiency and quality of the rolled round work.
