Ⅰ. What is a plate rolling machine?
In the field of sheet metal processing, the use of plate rolling machines is indispensable. It is a device that uses working rollers to bend flat metal sheets into a circle. It can form parts of different shapes such as cylindrical parts and conical parts. It is a very important processing equipment. Plate rolling machines are divided into three-roller mechanical plate rolling machines and four-roller hydraulic plate rolling machines.
Ⅱ. What is the most important operation of a plate rolling machine?
The most important operation link of a plate rolling machine is pre-bending before rolling, which can bring unexpected effects to our work and products.
Ⅲ. Is it necessary to pre-bend before rolling? What are the benefits of pre-bending?
1. Eliminate straight edges
If the plate is rolled directly without pre-bending, there will be obvious straight edges at both ends of the plate, making it difficult to roll into an ideal cylindrical shape. Pre-bending can bend both ends of the plate in advance, so that a complete cylinder can be formed smoothly in the subsequent rolling process.
For example, when manufacturing large cylindrical storage tanks, if pre-bending is not performed, the straight edges at both ends of the plate will affect the sealing and structural strength of the tank body.
2. Improve the quality of plate rolling
Pre-bending can improve the force distribution of the plate during the rolling process, reduce defects such as deformation, wrinkles or cracks caused by local stress concentration, and thus improve the quality and accuracy of the plate rolling.
Taking the manufacture of pressure vessels as an example, if the quality of the plate rolling is poor, it may cause serious consequences such as leakage or even explosion of the container during use.
3. Increase the efficiency of plate rolling
The pre-bending plate is smoother during the rolling process, reducing the time for repeated adjustments and corrections, thereby improving the efficiency of the entire plate rolling operation.
For example, in the batch production of cylindrical parts, pre-bending can significantly shorten the production cycle and reduce production costs.
4. Ensure dimensional accuracy
Pre-bending helps control the final size and shape of the plate, making it more in line with the design requirements and improving the consistency and reliability of the product.
Assuming that the dimensional accuracy of the pipe connector is not up to standard, it may cause loose connection and affect the normal operation of the pipeline system.
In summary, pre-bending before rolling is essential. For better product effects, ZYCO recommends that every customer use the plate rolling machine according to our suggestions.
