Use and Maintenance of NC Punch Die
模具应定期清洗和油润。
Mold should be cleaned and oiled regularly.
不同板厚不同材质应选用不同的下模间隙，间隙过小易啃模，过大则毛刺大。
Different plate thickness and different material should choose different lower die clearance, too small clearance easy to gnaw die, too large burr.
不同材质板材应选用不同材质模具，如不锈钢及铝铜板，应选用特殊用钢。
Dies of different materials, such as stainless steel and aluminium-copper plate, should be selected for different materials, and special steel should be selected for different materials.
要定期检查冲床上下的模座同轴性，模位不正，容易单边啃模或打坏模具。
It is necessary to regularly check the coaxiality of the upper and lower die seats on the punch press, and the die position is not correct. It is easy to gnaw or break the die unilaterally.
成型模具应将打击头从最低逐步向上微调到适当位置，否则，容易一次就造成打散模具。
The forming die should be fine-tuned from the lowest to the proper position step by step, otherwise, it will easily cause the die to be broken up at one time.
当发现上下模刃口磨损达R0.25毫米的圆弧时，就需要重新刃磨。
When it is found that the upper and lower die edges are worn to R0.25mm arc, it is necessary to re-grind.
每次刃磨量（吃刀量）不应超过0.013毫米，磨削量过大会造成模具表面过热，相当于退火处理，模具变软，大大降低了模具的寿命，刃磨时必须增加足够的冷却液。
Each grinding amount (feed amount) should not exceed 0.013 mm. Excessive grinding amount will cause die surface overheating, which is equivalent to annealing treatment, die softening, greatly reducing the life of the die, and sufficient cooling fluid must be added during grinding.
刃磨完后，边缘部要油石处理，去掉过分尖锐的棱线，并退磁和上油。
After grinding, the edge should be treated with oil stone, removing excessively sharp edges, and demagnetizing and oiling.
当入模深度不够时，将打击头的高度调整为要求尺寸。
When the penetration depth is not enough, the height of the hitting head is adjusted to the required size.
模具的刃磨量是一定的，数控微信公号cncdar如果达到该数值，冲头就要报废。如果继续使用，容易造成模具和机器的损坏，得不偿失。
The grinding capacity of the die is certain. If the numerical control Wechat company cncdar reaches this value, the punch will be scrapped. If it continues to be used, it is easy to cause damage to the mould and machine, which is not worth the loss.
更换模及刃模时，启动设备前后应注意安全，以防设备、模具、人身受损。
When replacing the die and blade die, attention should be paid to safety before and after starting the equipment in order to prevent damage to the equipment, the die and the person.
