卷料成本取决于材料种类、厚度和表面光洁。它占冲压生产成本的30％～70％。如果材料得不到合理利用,冲压生产的成本可能更高。假如压力机行程每分钟为500次,每次产生2g废料,那么每8小时就会浪费将近半吨的材料。因此,应根据冲件的特点和质量要求,在保证模具强度和不影响压力机工作的前提下,设计少废料排样。下面例举一些能改善材料利用率和提高生产效率的方法。 1.多行排样设计排样主要是依据冲压件的形状、尺寸和复杂程度。一般,单行排样每次冲压行程只
The cost of the coil depends on the material type, thickness and surface finish. It accounts for 30% to 70% of stamping production costs. If materials are not used properly, the cost of stamping may be higher. If the press travels 500 times per minute, producing 2 grams of scrap each time, nearly half a ton of material is wasted every eight hours. Therefore, should be based on the characteristics of the pieces and quality requirements, to ensure the strength of the mold and does not affect the press work under the premise of less scrap design layout. Here are some ways to improve material utilization and increase productivity. 1. Multi-row layout design Layout is mainly based on the shape of the stamping parts, size and complexity. In general, single row layout stamping stroke only
