According to the analysis of the cause of the accident of the power press, the dangers of the press operation of the power press mainly include the following aspects:
1. The danger of power press structure
A considerable part of the stamping equipment uses a rigid clutch. This is the use of a cam mechanism to engage or disengage the clutch. Once engaged, it must complete a cycle before stopping. If the hand cannot be drawn out of the mold in time during this cycle, a hand injury will inevitably occur.
2. Movement out of control
The power press will also be subjected to frequent strong shocks and vibrations during operation, causing some parts to be deformed, worn or even broken, causing the equipment to run out of control and cause dangerous continuous impact or accidents.
3. Switch failure
Malfunction of switch control system of power press due to human or external factors.
4. The danger of mold
The mold is responsible for the main function of processing and forming the workpiece, and is the concentrated release part of the energy of the entire system. Because the mold design is unreasonable or defective, the safety of the operator during use is not taken into account. During operation, the hand must be directly or frequently reached into the mold to complete the operation, so the possibility of injury is increased. Defective molds may cause accidents under normal operating conditions due to wear, deformation, or damage.
