A bending machine is a common industrial equipment used for bending metal sheets and other materials. While these machines greatly improve production efficiency, improper operation can also pose serious safety risks. To ensure the safety of operators and prevent workplace accidents, this article will detail the safety precautions to be observed when using a bending machine.
Understanding the Basic Operation and Risks of a Bending Machine
Before starting the operation of a bending machine, users must understand the basic functions, operational processes of the machine, and potential risk points. Common risks include hand injuries, being struck by machine components, and equipment damage due to improper operation. Therefore, training and education before operation are essential.
Wearing Appropriate Personal Protective Equipment (PPE)
When operating a bending machine, wearing suitable personal protective equipment is a basic requirement to ensure the safety of the operator. Necessary protective equipment includes:
- Safety glasses: to prevent metal chip splashes or liquid from injuring the eyes.
- Work gloves: to protect hands from cuts and heat injuries.
- Earplugs or earmuffs: to reduce the risk of hearing damage from prolonged exposure to high noise levels.
- Safety shoes: wearing steel-toed shoes can protect toes from injuries caused by falling heavy objects.
Checking the Safety Devices of the Bending Machine
Ensure all safety devices are in good condition and correctly set up, including:

(3) Initial Setup and Adjustment of a Bending Machine: A Guide to Adapt to Different Bending Needs
In the metalworking industry, a bending machine is a fundamental and indispensable equipment used to bend metal sheets into the desired shapes and angles. To adapt to different bending requirements, operators must understand how to perform the initial setup and adjustment of a bending machine. Proper setup not only enhances production efficiency but also ensures processing quality and operational safety. This article will detail the initial setup and adjustment process of a bending machine.
Understanding the Basic Components of a Bending Machine
A bending machine mainly consists of a bed, press plate, dies, control system, etc. The key to initial setup and adjustment lies in correctly installing the dies and setting appropriate bending parameters. Dies typically include upper and lower dies, with the upper die directly in contact with the metal sheet and the lower die supporting the sheet, completing the bending process together.
Initial Setup Steps
1. Install the dies:
- Select suitable dies based on the thickness of the processed sheet and the bending radius. Ensure the dies are clean and free of impurities to avoid damaging the sheet during processing.
- Install the dies in the corresponding positions on the machine, typically with the upper die mounted on the dynamic press plate and the lower die on the machine bed's worktable.
2. Adjust the die clearance:
- The die clearance directly affects the bending quality and the sheet's elastic recovery. The clearance size should be adjusted according to the sheet's thickness and material. Generally, the clearance is about 8 times the sheet's thickness.
3. Set pressure and stroke:
- Adjust the pressure based on the sheet's thickness and bending length to ensure the pressure is sufficient to bend the sheet but does not cause breakage.
- Setting the stroke requires ensuring the press plate can fully press down to the appropriate position, achieving the predetermined bending angle.
Adjusting Bending Parameters
1. Control system settings:
- Modern bending machines often use CNC systems, allowing input of bending parameters such as angle, pressure, stroke, etc., through the control panel.
- For complex bending tasks, multiple steps may need to be set, each step potentially involving different angle and pressure settings.
2. Adjusting bending angles:
- The accuracy of bending angles is crucial in high-quality bending processes. Pre-set angles based on design requirements and material characteristics, considering the material's elastic modulus for proper adjustment.
3. Testing and calibration:
- Before starting mass production, conduct several test bends to check the bending angle and the sheet's elastic recovery.
- Based on the test bend results, adjust parameters until the optimal bending effect is achieved.
Safety and Maintenance
- Check safety facilities: Ensure all safety devices such as emergency stop buttons, safety light curtains, etc., are working properly.
- Regular maintenance: Regularly inspect the machine's hydraulic system, electrical system, and mechanical components, promptly replace worn parts, lubricate moving parts, ensuring the machine's stable and safe operation.
By following the above initial setup and adjustment steps, operators can ensure efficient and precise bending operations according to different processing requirements. This not only improves production efficiency but also guarantees product processing quality, prolongs the equipment's lifespan, and ensures operator safety. Correct setup and maintenance are key to the efficient operation of a bending machine.
