  • 机械零件材料选用的原则要考虑三个方面的要求
  • 本站编辑:杭州思良塑料模具有限公司发布日期:2020-03-12 09:50 浏览次数:

1、使用要求(首要考虑)

  1)零件的工况(震动,冲击,高温,低温,高速,高载都应当慎重对待);

  2)对零件尺寸和质量的限制;

  3)零件的重要程度。(对于整机可靠度的相对重要性)

  2、 工艺要求

  1)毛坯制造(铸造,锻打,切板,切棒);

  2)机械加工;

  3)热处理 ;

  4)表面处理。

  3、经济性要求

  1)材料价格(普通圆钢与冷拉型材,精密铸造,精密锻造的毛坯成本与加工成本的对比,);

  2)加工批量和加工费用;

  3)材料的利用率;(如板材,棒料,型材的规格,合理的加以利用)

  4)替代(尽量用廉价材料来代替价格相对昂贵的稀有材料,如在一些耐磨部位的套用球墨替代铜套,用含油轴承替代车削加工的一些套,速度负载不大的情况下,用尼龙替代钢件齿轮或者铜蜗轮等等)。

1. Requirements for use (primary consideration)

1) The working conditions of parts (vibration, shock, high temperature, low temperature, high speed, and high load should be treated carefully);

2) restrictions on the size and quality of parts;

3) The importance of the part. (Relative importance to overall machine reliability)

2, process requirements

1) blank manufacturing (casting, forging, cutting plate, cutting rod);

2) mechanical processing;

3) heat treatment;

4) Surface treatment.

3. Economic requirements

1) material price (comparison of raw round steel and cold drawn sections, precision casting, precision forging cost and processing cost);

2) processing batch and processing cost;

3) the utilization rate of materials; (such as the specifications of plates, bars, profiles, reasonable use)

4) Replacement (as much as possible to replace the relatively expensive rare materials with cheap materials, such as the use of ductile ink to replace copper sleeves in some wear-resistant parts, oil-based bearings to replace some of the turning process, under the condition of low speed load, nylon Replace steel gears or copper worm gears, etc.).
