Analysis of stamping part drawings and manufacturing precautions

（1） The analysis and manufacturing of stamping parts are carried out through the part drawings of the product. Therefore, when designing the stamping production process for related parts, designers need to start from the design drawings of the parts. 1. The stamping process for economically manufactured automotive parts has a wide range of applications, and the operation of stamping process is relatively convenient, thus it can generate high productivity. During the stamping process, the economic viability is significantly affected by the cost of the grinding tool, which has a significant impact on the batch production. The production cost of individual processing of stamping parts is inversely proportional to the production batch, and the smaller the production batch, the higher the cost consumption of stamping technology. Therefore, if the number of parts produced is relatively small, using other solutions is more suitable for the economic benefits of the enterprise. In the process of manufacturing stamped parts, it is necessary to combine multiple production plans to maximize the economic benefits of the enterprise. 2. Process oriented stamping parts; During the production process, the difficulty of its components is reflected accordingly. From the perspective of technology, the analysis mainly focuses on the degree, material properties, and dimensions, and the basic requirements need to comply with the regulations of stamping technology. In addition, the processability is also reflected in its ease of operation, fewer required processes, and stable quality. Normally, the structure and degree of stamped parts will affect the final processability of stamped parts. If the processability of the parts is poor, appropriate modifications need to be made to the part drawings to improve the processability of stamped parts. （2） Precautions for stamping parts manufacturing: Install dual hand brake switches on semi-automatic and manual punching machines, and it is strictly prohibited to press the switch with foot or one hand. After the high impact adjustment is completed and normal stamping is carried out, close the soundproof box (except for the packaging of product 8065 during inspection). During continuous stamping, employees are not allowed to pick up products by hand within 1 meter of the punch press. When the technician is debugging the machine, only one person can debug it, not two people. Technicians can only adjust the machine and feed materials outside the machine, with a distance of no less than 1M. When installing the mold, tighten the screws and stop the machine after 4 hours to check if the screws are loose. When there is a problem with the mold during the production process and it does not need to be removed, it is necessary to first turn off the power of the injection molding machine and hang a maintenance sign on the power box before repairing the mold. All tools should be returned to the toolbox after use and should not be placed on the machine to prevent them from slipping and injuring people. When the machine is not in production, the power supply should be cut off in a timely manner. When dealing with small workpieces, specialized tools should be used and direct feeding or retrieval by hand is not allowed. Producers should stand appropriately, maintain a distance between their hands and head and the punch press, and always pay attention to the action of the punch press. It is strictly prohibited to chat with others. Metal stamping parts; Operators and mold repairers are strictly prohibited from putting their hands into the mold during production. Operators are strictly prohibited from reaching their hands onto the motor to clean up waste when installing the suction fan. It is strictly prohibited to wear slippers during work to avoid hitting feet with molds, iron blocks, etc. in the workshop. The class monitor, fitter, and mold repairman wear protective shoes when going to work; Male operators are strictly prohibited from keeping long hair, while female operators must tie up their long hair to prevent it from getting caught in the flywheel. Attention should be paid to other oils such as white oil, alcohol, cleaning agents, etc. Gloves should be worn when packing materials, waste, and molds to avoid scratching hands. When there is oil, it should be cleaned in a timely manner to avoid slipping and falling. It is strictly prohibited to wear gloves when drilling and milling machines; Wear a mask and eye protection when using the grinder to protect yourself. Pay attention to dragging the mold to prevent it from falling to the ground (the flatbed truck must be placed on it to transport the mold). Non electricians are strictly prohibited from connecting electricity and repairing machines. It is strictly prohibited to aim the air gun at people to blow, as it may harm the eyes. The operator needs to wear earplugs. When abnormalities are found in the machine, turn off the power first and then promptly seek assistance from the on duty technician. Unauthorized handling is not allowed. When new employees start work, the team leader should explain the operating procedures to them and study them once a week every day. When adjusting the machine, it should be adjusted to a single action and it is strictly prohibited to use a linked discharge belt. No flammable or explosive materials can be stored under the electric switch. Operators are strictly prohibited from chasing or hitting in the workshop to avoid falling, knocking over products, or injuring themselves. Perform equipment inspection according to the inspection content on the equipment inspection card, paying special attention to whether the guiding and braking devices of the punching machine are operating normally, and whether the single punch and continuous punch functions are clear. When installing the mold on the small punch (10T), first loosen the locking device of the guide rail, install the upper and lower molds, and then adjust the travel of the guide rail until it meets the requirements and lock the fastening device. In addition, when the high punch is used to mount the mold, hit the single stroke. After the upper mold is locked, the lower mold is locked after the oil pressure mold locking, and then checked again before production. The tools (pliers, hooks) used for discharging or manually picking up raw materials are strictly prohibited from manually feeding or picking up raw materials. Single switch may hurt hands, dual switch is needed. The machine cannot leak oil, otherwise it will fall off. Do not expose the power supply, it is dangerous. Wear gloves and concentrate when stamping iron sheets, otherwise your hands may be injured. In work, first check if there are any abnormalities in the operation of the equipment, such as unclear single or continuous flushing, ineffective operation, or electrical faults. Stop the machine immediately and seek timely assistance from the on duty technician. The use of foot switches is strictly prohibited for punching machines, and all original equipment on the machine must be removed. When cleaning and inspecting equipment, cut off the power before operation. Cut off the power, clean and scrub the workbench, remove the mold for maintenance and storage, and check the lubrication system oil regularly every week.
