Bending machines, I think everyone knows that they belong to heavy industry, and the risk factor is relatively high. Therefore, the country pays more attention to it and has infrared safety protection devices. The following is explained by Xiaobian for everyone:
      The working process of the infrared protection device of the bending machine can be divided into two areas: dangerous area and safety area. Safety protection is needed in the dangerous area. The safety area must meet the production dangerous area. The bending machine is in contact with the bent workpiece. until. In this area, if the shading occurs, it is necessary to immediately issue a dangerous stop signal to the control circuit of the bending machine to control the bending of the bending machine to stop. According to the working principle of the bending machine, before the pressure is applied, the upper knife automatically returns to the starting position. When the pressure is started, if the safety light curtain is blocked, the upper knife automatically stops.
     The safety zone refers to the knife returning to the initial end at the beginning of the bending and bending. This area does not require an infrared protection device to control the bending machine to stop. It is the working area:
When the bending machine works to bend the workpiece, the workpiece is upturned and the safety light curtain is blocked. If the infrared protection device sends a stop signal to the bending machine at this time, it cannot be produced at all.
This is the problem that most safety light curtain manufacturers have not solved, and it is the real reason why most of the bending machine equipment has a safety light curtain installed.
     Technical breakthroughs, overcoming difficulties, the introduction of SZZ type bending machine special safety light curtain, the same safety light curtain is also divided into two corresponding areas, in the danger zone to achieve control of the bending machine at any time
stop. The bending machine is not controlled in the safe area, so that the bending machine can be processed and produced safely and conveniently. In order to achieve safety protection while meeting normal production, the bending machine is used to ensure the safety of the enterprise.
The problem is to protect both the workers and the enterprises, and the economic benefits and social benefits are obvious.
