路沿石模具设计难点
Difficulties in the design of the road along the stone
1、质料的合理利用
1, reasonable utilization of material
质料利用率：冲裁件的实际面积与所用板料面积的百分比，它是衡量合理利用质料的经济性指标。
Material utilization ratio: the actual area of the blanking parts and the percentage of the area used, it is an economic index to measure the rational utilization of materials.
1个步距内的质料利用率
The utilization ratio of material within 1 steps
1张板料(或带料、条料)上总的质料利用率
The total material utilization rate of 1 sheets (or strip and strip).
板料的裁剪要领
Cutting edge of sheet material
2、提高质料利用率的要领
2. The essentials of improving the utilization ratio of material
冲裁所孕育产生的废料：1类是布局废料；另1类是工艺废料。
The waste generated by blanking is: the 1 category is layout waste, and the other 1 is process waste.
工艺废料与布局废料
Waste and layout waste
布局废料是由制件本身的形状决定，1样平常是牢固稳定的；工艺废料取决于搭边与余量的大小，也取决于排样要领与冲压要领。因此，要提高质料的利用率，就要合理排样，淘汰工艺废料。
The waste of the layout is determined by the shape of the part itself, and the 1 is usually firm and stable; the waste of the process depends on the size of the side and the allowance, and also on the layout and stamping essentials. Therefore, in order to improve the utilization rate of materials, rational layout and elimination of technological wastes are necessary.
计划合理的排样方案；
Plan reasonable layout plan;
选择切合的板料规格与合理的裁板法（淘汰料头、料尾与边余料）；
Choose suitable gauge for sheet metal and reasonable cutting method.
利用废料作小0件（如肴杂排样）等。
Use waste to make 0 small pieces, such as dishes.
