Time stamping the highest accident rate occurred in the delivery, reclaiming phase, and a considerable number of our country also continues to rely on hand-stamping machine to send, take material. A cheap solution to this problem is to use simple hand tools. The role of hand tools are tools on behalf of the hand, to avoid the operator reaches into the risk model mouth area. Hand Tools is the host in the press outside the safe operation of the user's hand to provide additional operational tools. Many types of hand tools, commonly used hand pliers, hook, tweezers, clips, all kinds of sucker (electromagnetic, vacuum, permanent magnet) and process-specific tools, is the safe operation of the aids. Hand tool design and selection should note the following: 1. Meet the safety requirements of hand tool, ergonomic handle shape for the operator's hands to control, and can stop in the force, the hand grip to move forward can not be achieved or unsafe position, to avoid improper use of tools by injury. 2. Simple structure, easy to use hand tool, the work of the position should be matched to the shape of the blank holder to facilitate gripping, reliable, quick to take delivery, accurate and into the mold. 3. Shall not damage the hand tool, mold should be made with soft material to prevent accidental circumstances, the tool does not die out in time population, while in the mold has closed, the resulting press overload. 4. Meet the safety requirements of hand-held power tools should be used hand-held power tools safe voltage, and to ensure insulation. 5. Operating position and posture should be consistent with the safety requirements of ergonomics for the operator as to provide comfortable and safe working conditions in order to more effectively develop people, and improve productivity. Some of the practices of foreign countries for reference, such as Japan, the job of stamping out the standard operating size. Not only in the press to consider the size of the design parameters of the body, but also set the elbow pallet, height-adjustable chairs and foot pedal to increase the operating comfort. 6. Provide a good physical and psychological working environment, work environment temperature, ventilation, lighting, noise and vibration should be consistent with the labor hygiene requirements. If the Dam to the requirements of reform measures to be adopted. 7. Labor protection products with dimensions in the environmental management standard operating before or during the transformation of transformation, should be equipped with necessary labor protection products, such as ear plugs (ear), operating gloves in order to strengthen the protection of personnel. It should be stressed that in normal operation, insisted on reducing the use of hand stamping tools can really play a role in the accident, but the hand tool itself does not have the basic functions of safety devices, which are not safety devices. It can only replace the staff into his danger zone, can not prevent the operator's hand accidentally inserted into the danger zone. Use of hand tools safety devices must be used simultaneously. Stamping operations monotonous, repetitive, easily lead to operator fatigue; noise and vibration down the operation of consciousness, which is one of the important reasons that lead to accidents. If the operator's posture is not correct, will accelerate the fatigue, increase risk, so the operating position and posture, as well as the factors surrounding environment should be given adequate attention.
