What are the safety points of hardware mold design? In terms of structure, the convenience of feeding, ordering, discharging, and cleaning up waste materials should be ensured as much as possible. For the processing of small parts, it is strictly forbidden for the operator's fingers, wrists or other parts of the body to extend into the mold area; for the processing of large parts, if the operator wants to enter the mold by hand, the scope of the mold should be minimized. Minimize the time that a certain part of the body stays in the mold as much as possible, and the danger zone of the mold should be clearly defined, and necessary protective measures and devices should be equipped.
The various parts on the mold should have sufficient strength and rigidity to prevent damage and deformation during use. The fastening parts should have anti-loose measures to avoid accidental injury to the operator.
It is not allowed to produce waste or workpiece missiles during the processing, which will affect the attention of the operator or even hurt the operator. In addition, it is necessary to avoid cuts from the burrs of the blanking parts. Operators are not allowed to have too much motion range during the punching operation, to avoid the posture that makes the body lose stability; excessive and over-accurate movements are not allowed during the operation. Should try to avoid strong noise and vibration during stamping processing.
The mold design should indicate the mold weight on the general drawing for easy installation and safety. Lifting and handling measures should be adopted for the processing of parts over 20 kg to reduce labor intensity. When assembling and disassembling mold parts, it should be convenient and safe to avoid the possibility of pinching or cutting hands; the mold should be easy to disassemble and store. In short, even minor problems in the mold will affect safety. Only by analyzing the specific problems in each operation can the safety precautions in the mold be put forward.
