| 高速护坡模具材料的选用既要满足客户对产品质量的要求,还需考虑到材料的成本及其在设定周期内的强度,当然还要根据模具的类型、使用工作方式、加工速度、主要失效形式等因素来选材。例如:冲裁模的主要失效形式是刃口磨损,就要选择表面硬度高、耐磨性好的材料;冲压模主要承受周期性载荷,易引起表面疲劳裂纹,导致表层剥落,那就要选择表面韧性好的材料;拉深模应选择磨擦系数特别低的材料;压铸模由于受到循环热应力作用,故应选择热疲劳性强的材料;对于注假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温塑模,当塑件为abs、pp、pc之类材料时,高速护坡模具材料可选择预硬调质钢,当塑件为高光洁度、透明的材料时,可选耐蚀不锈钢,当制品批量大时,可选择淬火回火钢。 The selection of materials for high-speed slope protection moulds should not only satisfy customers'requirements for product quality, but also take into account the cost of materials and their strength in the set period. Of course, materials should be selected according to the type of moulds, working methods, processing speed, main failure forms and other factors. For example, the main failure mode of punching die is edge wear, so it is necessary to select materials with high surface hardness and good wear resistance; punching die bears periodic load, which easily causes surface fatigue cracks, so it is necessary to select materials with good surface toughness; drawing die should choose materials with very low friction coefficient; die casting die should have strong thermal fatigue because it is subjected to cyclic thermal stress. For injection moulds, when the plastic parts are abs, pp, PC and other materials, high-speed slope protection moulds can choose pre-hardened and tempered steel, when the plastic parts are high gloss and transparent materials, corrosion-resistant stainless steel can be selected, and when the mass of products is large, quenching tempered steel can be selected |
