在设备制造中,最大限度的节约材料,是降低制造成本的关键。实践证明,材料限额由项目工艺编制人员制定比较合适。因为①工艺人员对所负责项目的图纸了如指掌;②工艺人员直接编制制造工艺,对加工手段、胎模具情况、技术要求等都很清楚;③工艺人员比较容易发现图纸中存在的问题或材料数量的误差。在编制设备材料限额中,难度比较大的要算是异形板材了。如瓜瓣形封头、锥形封头、翻边锥形过渡段等。这些件的展开形状比较复杂,给编制带来了困难。材料使用限额不仅决定于自身的几何形状,而且还受板材的规格、制造厂的加工能力、已有胎模具的尺寸及技术
In equipment manufacturing, maximizing material savings is the key to reducing manufacturing costs. Practice has proved that the material quota is more appropriate for the project process staff. Because 1 craftsman knows well the drawings of the responsible project; 2 the craftsman directly compiles the manufacturing process, and it is very clear about the processing means, the condition of the tire molds, the technical requirements, etc.; 3 the craftman can easily find the problems or the quantity of materials in the drawings. error. In the preparation of equipment material limits, the more difficult to be counted as shaped plates. Such as melon-shaped head, conical head, flanging cone transition. The unfolding shape of these parts is more complicated and brings difficulties to the preparation. The material use limit is not only determined by its own geometry, but also by the specification of the sheet, the processing capability of the manufacturer, the size and technology of the existing tire mold.
