Intelligent safety protection system of rivet machine

risk assessmentThe riveter rivets down, causing serious injury to the operator's fingers, etc.

Operation principle: the rivet intelligent safety protection device is composed of a complete set of systems, including mechanical control, independent control box, multi-functional sensors, multiple adjustable finger proof probes, etc.

Protection principle: place the processed products, set the safety protection distance, fix the probe, and start the equipment for processing operation; when the finger is placed on the workpiece, the downward probe blocks and detects, the probe immediately stops the foot switch signal and cannot move the riveter downward; when the finger leaves, start the foot switch again, and the probe cannot detect the obstacle; The riveting machine of the equipment shall process rivets immediately to protect the safety of operators' fingers.

The main parts include: the safety box controller is respectively connected with the foot switch signal of the driving device, the limit device and the rivet machine, and the controller sends the start signal to the foot switch according to the falling of the protective component to the preset safety position; the controller controls the driving device to move down in the sensing range according to the start signal, and waits for the falling of the protective component to the preset safety In full position, the controller sends a start signal to the foot switch to open the rivet machine. The riveting machine can only be opened by foot switch when there is no obstacle in the free falling stroke of the protective component, so as to avoid injury to the fingers of the operator and better protect the safety of the personnel.

The connector of the protection component can be customized according to the customer's requirements: to ensure that it meets the product and site requirements, multiple finger probes can meet the needs of different equipment, The riveting machine and the welding machine are applicable; the driving device and the limiting device are installed on the support frame to limit the moving range of the driving device; the protective component is movably installed on the support frame, and the part of the protective component extends under the punch of the riveting machine; one end of the auxiliary connecting piece is fixedly connected with the driving device, and the other end is fixedly connected with the protective group Active connections.

 Principle
铆钉机的智能安全保护系统

The riveting machine adopts the principle of double-sided two-point over-current riveting: when working, two electrodes pressurize the work piece to make two layers of metal form a certain contact resistance under the pressure of two electrodes, while when the riveting current flows from one electrode to the other electrode, the two contact resistance points form a momentary hot fusion, and the riveting current flows from the other electrode to the electrode along the two workpieces to form a circuit in a momentary manner, which will not hurt The internal structure of the riveted workpiece.

The safety system shall conform to sil3 safety level / Se: the design shall be standard and firm, and meet the requirements of man-machine and site. The safety products are preventive protection measures, active protection measures and personal safety of operators.

Note: the safety project must be carried out by the professional safety personnel of Lihong in the early stage of equipment risk assessment, safety loop design, etc. the safety design of the same equipment is different due to the processing method and processing products (i.e. each equipment is customized), which is designed by the professional safety personnel.
