Manhart How to determine the processing parameters of the bending machine?

Determining the processing parameters of the bending machine is a key step in ensuring processing efficiency and product quality. The following are clear steps and reference information for determining the machining parameters of the rolling and bending machine:
1、 Understand processing requirements
1. Material characteristics: Firstly, it is necessary to clarify the type, thickness, hardness, and yield strength of the processed material, as different materials have different requirements for processing parameters.
2. Bending requirements: Understand the required bending angle, bending radius, and precision requirements after bending.
2、 Determine basic parameters
1. Drum diameter: Select the appropriate drum diameter according to the processing requirements, usually available in specifications such as 38 millimeters, 50 millimeters, 60 millimeters, etc.
2. Drum width: The width of the drum is determined based on the width and shape of the processed material.
3. Turning radius: Determine the turning radius according to the bending requirements, common specifications include 500mm, 800mm, 1000mm, etc.
3、 Calculate the dimensions of the roll bending machine
1. Length (L): According to the length calculation formula of the drum bending machine, L=turning radius+2 x (drum diameter/2), the length of the drum bending machine can be calculated.
2. Width (W): The width of a roll bending machine is usually determined by adding a certain margin to the width of the conveyed item, for example, W=width of the conveyed item+50mm.
3. Height (H): The height of a roll bending machine is usually determined based on the height of the conveyed item plus 2 to 4 times the diameter of the drum, that is, H=the height of the conveyed item+(2-4) x (drum diameter/2).
4、 Determine roller pressure and speed
1. Pressure (P): The pressure of the roller has a significant impact on machining accuracy. Generally, the optimal pressure range is determined based on empirical formulas or experiments, and then gradually adjusted to the optimal state. Be careful to avoid material deformation or equipment damage caused by excessive pressure.
2. Speed (V): The speed of the roller should be selected based on the hardness and thickness of the material. In general, harder materials require lower speeds, while softer materials can increase speeds appropriately. The selection of speed should consider the balance between processing efficiency and product quality.
5、 Precautions
When determining processing parameters, reference should be made to the user manual of the bending machine and the manufacturer’s recommendations.
2. Conduct trial processing according to the actual situation, adjust the parameters based on the trial processing results until the best effect is achieved.
3. Regularly maintain and upkeep the rolling and bending machine to ensure that the equipment is in good condition, in order to improve machining accuracy and stability.
6、 Summary
Determining the processing parameters of a roll bending machine is a process that comprehensively considers material characteristics, processing requirements, and equipment performance. By selecting appropriate drum diameter, width, and turning radius, calculating the size of the bending machine, and determining parameters such as roller pressure and speed, processing efficiency and product quality can be improved. At the same time, pay attention to following operating procedures and precautions to ensure the safety of operators and the stable operation of equipment.
