Dangerous factors of stamping work and safety technical measures1

1. The risk factors in the stamping process are analyzed according to the general causes of stamping accidents. The accidents in stamping work are mainly caused by the following reasons: 1. The danger caused by the structure of the punch itself. At this stage, most of the punch presses are used. The still is a rigid clutch. Once the clutch connection is running, a stamping cycle must be completed before the electric flat car slider will stop running. If the punching worker's hand cannot be taken out of the mold in time during the under-punching process, a punching hand injury accident will occur. 2. Failure in the stamping process. The punch will produce shock and vibration during operation. Over time, the parts of the punch will be deformed, worn or even broken, which will cause the punch to lose control and produce continuous punching. This is a very dangerous situation. 3. Punch switch failure The punch switch fails due to man-made or long-term lack of maintenance, resulting in failure in the stamping process. 4. Unreasonable stamping die design stamping die is the basis for the production of stamping parts. Unreasonable stamping die design will greatly increase the possibility of stamping accidents. Normal stamping dies will also be worn, deformed or damaged as the use time increases, leading to accidents. 2. Safety technical measures for stamping operations 1. Stamping safety tools must be used. During the stamping process, use safety tools to put the product blanks into the mold and take out the stamped products and waste materials to achieve out-of-mold operations and avoid direct hands. Into the mold to ensure the safety of workers. 2. Protection of the working area of u200bu200bthe stamping die (1) Install a protective device around the stamping die. (2) Reasonable design of molds reduces the danger zone of stamping molds. (3) Design automatic or mechanical feeding. 3. Safety protection of the punch (1) Mechanical protection push-hand type. This is a protection device that is linked with the punch slider and pushes the worker's hand away from the die through the swing of the baffle. Swing rod hand guard. It is a device that uses the principle of leverage to move the hand away. Handle safety device. It is a device that uses pulleys, levers, and ropes to link the hand movements of the workers with the movement of the slider. (2) The dual-switch control system will only activate the slider when the punching worker’s hands press the two buttons at the same time. This completely eliminates the possibility that the worker puts his hand into the mold and the punch starts. (3) The safety grating installs the safety grating punch, which is equivalent to forming a protection zone for the entire dangerous area. When the worker enters the safety grating protection area, the punch cannot be started.
