What are the commonly used safety protection devices for stamping equipment?

Punching machine. At present, the commonly used safety protection devices are: safety start device, machinery.

Guards and automatic protective devices.

1) Safety start device: its functional feature is the clutch of the press when the operator's limb enters the danger zone.

If it cannot be closed, or the block cannot go down, the press can only be started when the operator's limb is completely out of the danger zone. This assembly includes: a double-handle coupling and a dual-button coupling.

The principle of this facility is that during operation, the operator must activate the switch with both hands at the same time, so that the press can be connected to the power supply and start working, thus ensuring safety.

2) mechanical protective equipment 1 is characterized by trying to separate the danger zone from the operator's hand when the slider goes down, or pulling the operator's hand out of the danger zone with a forced method, so as to ensure safe production. This type of protective equipment includes: protective plates, pusher-type protective equipment, and handle safety devices.

The mechanical protective loading dish has a simple structure and is convenient to manufacture, but it has a great impact on the interference of the operation.

3) Automatic protection device: its functional feature is to set up beam, air flow, electric field, etc. around the dangerous area of the die. Once the hand enters the danger zone, the press will automatically stop working through light, electricity and air control.

At present, the commonly used automatic protection equipment should be photoelectric protective basin. The principle is to set up a light emitter and a light receiver in the danger zone. One or more rays of light are formed.

When the operator's hand is wrong in the danger zone, the optical signal is converted into an electrical signal through the photocell, and the electrical signal is amplified and locked with the start control line, so that the slider of the press stops working immediately, so as to play a protective role.

In the stamping parts processing plant, it is necessary to use stamping protection tools to take certain protective technical measures for stamping operations;

In the stamping process, use protective tools to put the product blank into the mold and take out the stamped products and waste materials to achieve out-of-mold operations and avoid putting your hands directly into the mold.

1. Protection of the working area of the stamping die in the stamping parts processing plant.

1. Install guards around the stamping die.

2. Reasonable design of the mold is to reduce the dangerous area of the stamping die.

3. Design automatic or mechanical feeding.

Second, the stamping parts processing plant to the punching machine protective measures.

1. Push hand type. This is a kind of protection device that is linked to the punch slider and pushes the worker's hand away from the die through the swing of the baffle.

2. A pendulum gauntlet. It is a device that uses the principle of a lever to pull your hand apart.

3. Handle guard. It is a device that uses pulleys, levers, and ropes to link the worker's hand movement with the movement of the slider.

What are the commonly used safety protection devices for stamping equipment? I think the first thing is overload protection, and in addition, there must be a protective cover and a fence in front of the stamping equipment.

Stamping equipment is still relatively dangerous, so it is necessary to prevent personnel from being injured according to protective equipment.

1) Safe start device.

Its function is that when the limb of the Sakura enters the danger zone, the clutch of the press cannot be closed, or the slider cannot go down, and the press can only start working when the operator's hand completely exits the danger zone.

Such devices include: a double-handle coupling device and a double-button coupling device. The principle of this facility is that when operating, the operator must use both hands to activate the switch.

The press can be plugged in and start working.

Thus ensuring safety.

2) Mechanical guards.

Refers to when the slider is going down. Try to separate the danger zone from the operator's hand, or use a forced method to pull the operator's hand out of the danger zone to ensure safe production.

This type of protective device includes: protective plate, push handle protection device, handle safety device. The mechanical protective equipment is simple in structure and easy to manufacture, but it has a great impact on the interference of operations.

3) Automatic protection device.

The device is to set up a light beam, air flow, electric field, etc. around the dangerous area of the die, once the hand enters the danger zone, through light, electricity, air control, so that the press will automatically stop working. At present, the commonly used automatic protection blind pin device is a photoelectric protection device. The principle is to set up a luminaire and a light receiver in the danger zone to form one or more beams of light.

When the operator's hand mistakenly enters the danger zone, the beam is blocked, so that the optical signal is converted into an electrical signal through the photocell, and the electrical signal is amplified and locked with the starting control line, so that the slider of the press stops working immediately, so as to play a protective role in dust swimming.

The safety protection devices include safe start devices, mechanical protection devices and digital core automatic protection devices. The function of the safety start device is that when the operator's limb enters the danger zone, the clutch of the press can not be closed, or the slider can not go down, and only when the hand of the person who misses the operation completely exits the danger zone, the press can start to work.

The press has a safety guard and can be fitted with a safety light curtain. The safety light curtain is mainly composed of the luminaire and the light receiver group, and the light beam between the light emitter and the light receiver is formed by a light curtain, when the object blocks the light beam, it will give the light receiver a signal, and the mechanical branch will stop working, so as to avoid the occurrence of dangerous accidents.

1. There should be nameplates, various operation instructions, safety and warning instructions on the stamping equipment.

2. The power wiring should be standardized, and the cable of the equipment should not be damaged to prevent aging.

3. The door lock of the distribution box on the stamping equipment should be keyed, and the power supply should be automatically cut off when the door is opened.

4. The conversion of single, continuous, foot stamping and other operations should be changed by a transfer switch with key lock.

5. When the stamping equipment is operated in a single stroke, there shall be no continuous stamping stroke.

6. When continuous stroke operation is selected, there should be a pre-control action link during the operation.

7. There must be an emergency stop button on the stamping equipment, and it should be able to lock itself.

8. There should be interlocking control between foot operation and hand operation.

9. Protective covers should be installed for transmission gears, pulleys, flywheels, levers and other transmission parts exposed outside the fuselage and on the top of the fuselage.

10. The foot pedal operation device adopts the foot pedal type, which is controlled by the foot pedal for electrical switch and can be automatically reset.

11. There should be protective covers on the upper part and both sides of the pedal, and the pedal should be non-slip.

12. The stamping equipment must have safety protection measures to prevent hands from entering the mold closure area, and the user unit shall take safety measures for stamping operations such as automatic feeding and discharging, installation of safety protection devices, safety molds and the use of special tools for picking and feeding materials according to the types of stamping equipment and the shape of the workpieces produced by the products.

13. Regularly test the three tests of the electrical system (protective grounding, insulation, and withstand voltage test), and have a test report.

14. Each stamping equipment should obtain the "Stamping Equipment Safety License" and be within the validity period.

At present, the commonly used safety protection devices of stamping machinery are: safe start device, mechanical protection device and automatic protection device. (1) Safe starter grinding posture:

Its functional characteristics are that when the operator's limb enters the danger zone, the clutch of the press can not close the first hound, or the block can not go down, and only when the operator's limb completely exits the danger zone, the press can be started to work. This assembly includes: a double-handle coupling and a dual-button coupling.
