Why do bending machines need to be fitted with safety light grids？

In the metal processing industry, bending machines are indispensable and critical equipment, widely used for precision forming of steel plates, aluminum plates, stainless steel and other metal materials. However, as the working speed and automation of the equipment increase, the safety of the operators is also attracting more and more attention. As a professional bending machine manufacturer with 10 years of experience, we have a deep understanding of equipment safety issues. This article will combine our many years of technical experience, in-depth analysis of why the safety grating is a key device to protect the operation of the bending machine safety, from the multi-dimensional selection and maintenance guide, to help you feel more comfortable, more efficient into production.

1.What is safety light grating?

Safety encoder is mainly composed of two parts: transmitter and receiver. The transmitter emits one or more beams of infrared light, these infrared rays will be reflected back when encountering obstacles, the receiver receives the reflected infrared rays, will be converted into electrical signals, and then control the action of the equipment. When the operator or his clothing and other parts of the infrared blocked, the receiver will immediately receive the signal, and quickly respond to stop the mechanical equipment, thus avoiding potential safety risks.

2. Why bending machine must be equipped with safety grating?

(1) Prevent operators from being injured: During the working process of a bending machine, its moving parts may cause injury to the human body. The safety grating can cut off the power supply in time when the operator enters the dangerous area, thus avoiding accidents.
(2) Improve production safety: the installation of safety grating can reduce the safety hazards in the production process, to create a safer working environment for the operator, thereby improving production safety.
(3) guarantee production efficiency: through the protection of safety grating, can avoid equipment failure and production stagnation caused by operator misoperation, so as to guarantee production efficiency and product quality.

3. The role of safety light grating

(1) real-time monitoring: safety grating by transmitting and receiving infrared rays, real-time monitoring equipment around the security situation, to ensure the safety of operators and equipment.
(2) rapid response: once an object enters the monitoring range of the safety grating, the safety grating will immediately cut off the power supply, thus avoiding accidents.
(3) easy to install and maintain: safety grating installation and maintenance is relatively simple, no need for complex operation process, can save a lot of time and energy for the user.

4. How to choose the right safety grating?

(1) inspection height and resolution: according to the bending machine mold size selection grating detection height, usually need to cover the entire hazardous area. The smaller the resolution (optical axis spacing), the higher the detection sensitivity, recommended to choose ≤ 14mm high-resolution models.
(2) safety level certification: to ensure that the grating in line with international safety standards, to meet the requirements of the Machinery Safety Directive.
(3) Environmental adaptability: If the workshop environment is dusty, oil, need to choose IP67 and above protection grade products to ensure long-term stable operation.

5. Safety grating installation and maintenance

(1) Installation points: grating transmitter and receiver are strictly aligned to avoid angular deviation. The installation position is at least 50mm away from the dangerous area to prevent mechanical vibration leading to false triggering. It is recommended to install and debug by professional technicians to ensure the trigger accuracy.
(2) Daily maintenance: Regularly clean the grating surface dust to ensure infrared penetration. Quarterly function test to verify the response speed and emergency stop effect.

Bending machine as a high-risk, high-value processing equipment, safety protection is not optional, but the responsibility of the enterprise to employees and customers. Safety light barriers are a central tool for achieving this.
