AHYW China Yawei CNC Press brake Bending Thick Sheet Material
AHYW Yawei electro-hydraulic servo bending machine is a high-precision equipment widely used in metal sheet processing, especially in the field of thick plate processing, where its efficiency, stability, and precision are fully demonstrated. Thick plate bending processing demands high requirements for equipment, not only requiring strong bending force but also an accurate control system to ensure processing quality. The following is a detailed analysis of the method and key technologies for processing thick plates with an electro-hydraulic servo bending machine.
AHYW Yawei CNC Press brake-Technological characteristics of thick plate bending
Compared to thin plate bending, thick plate bending has the following characteristics:
High bending force requirement: Due to the high thickness and strength of thick plates, a larger bending force is required to ensure smooth forming of the plates during bending.
The springback phenomenon is evident: during the bending process of thick plates, due to the release of internal stress within the material, the springback phenomenon is prone to occur, affecting the bending accuracy.
Severe mold wear: The processing of thick plates causes significant wear to the mold, necessitating the selection of mold materials with high hardness and wear resistance.
High machining accuracy requirements: Thick plates are typically used for important structural components, which require high precision in bending angles and dimensions.
Advantages of AHYW Yawei electro-hydraulic servo bending machine
The electro-hydraulic servo bending machine combines the powerful power of the hydraulic system and the high-precision control of the servo motor, which can well meet the needs of thick plate processing. Its main advantages include:
High precision control: The combination of servo motor and hydraulic system can achieve precise control of bending angle, speed, and pressure, reducing rebound phenomenon.

The key steps of thick plate bending processing AHYW Yawei China made CNC Press brake
Material selection and preparation
Select suitable thick plate materials based on processing requirements, such as carbon steel, stainless steel, or aluminum alloy.
Check the surface quality and dimensions of the board to ensure there are no defects such as cracks or scratches.
According to the bending requirements, pre treat the board, such as deburring and cleaning the surface.
Mold selection and installation
Select the appropriate upper and lower molds based on the thickness of the board and the bending angle. Thick plate processing usually uses V-shaped molds, and the width of the mold opening should be greater than the thickness of the plate.
Ensure that the mold is securely installed to avoid looseness or displacement during the processing.
Check the wear of the mold and replace or grind it if necessary.
Equipment parameter settings
Set parameters such as pressure, speed, and stroke of the bending machine based on the material, thickness, and bending angle of the board.
Use a CNC system to input bending programs, ensuring automation and precision in the machining process.
For thick plate processing, it is usually necessary to bend step by step, that is, multiple bends to achieve the target angle, in order to reduce rebound and material stress.

After starting the device, observe whether the bending process is smooth and avoid abnormal vibration or noise.
Monitor the bending angle and size to ensure compliance with design requirements. For rebound phenomenon, it can be compensated by adjusting the bending angle or increasing the holding time.
For thick plates with complex shapes, segmented bending or multi axis linkage technology can be used to ensure forming accuracy.
Quality inspection and subsequent handling
After the bending is completed, use measuring tools to check the size and angle of the board to ensure that it meets the design requirements.
For workpieces with high surface quality requirements, subsequent treatments such as grinding and polishing can be carried out.
Record processing parameters and quality data to provide reference for subsequent production

spring back
Reason: Due to the release of internal stress in the material.
Solution: Increase the bending angle compensation value, or adopt a step-by-step bending and pressure holding process.
Inconsistent bending angle
Reason: The mold installation is not firm or the equipment parameters are not properly set.
Solution: Check the installation status of the mold and recalibrate the equipment parameters.
Surface damage on the board
Reason: The surface of the mold is rough or there are foreign objects on the surface of the board.
Solution: Grind the surface of the mold and clean the surface of the board.
Insufficient bending force
Reason: The equipment pressure is set too low or the hydraulic system is malfunctioning.
Solution: Adjust the pressure parameters and check if the hydraulic system is operating normally.
