A Brief Introduction To Isothermal Forging Technology

等温技术是在传统技术的基础上发展起来的一种新技术 die forging technology. Different from ordinary die forging technology, 同时将模具和坯料加热到锻造温度. 这使坯料在较窄的温度变化范围内完成变形过程.

The advantages of isothermal forging are:

  1. Greatly reduces the rheological resistance of the metal, 其总压力相当于普通模锻的10-20%. Save equipment investment and power consumption.
  2. Significantly improve the plasticity of metal materials. 因此,坯料具有良好的流动性,容易填充型腔. After forging, the dimensional accuracy of the workpiece is high, and the machining allowance is small, even without machining.
  3. 等温锻造技术可以制造形状复杂的锻件, thin walls, and high ribs formed at a go. 普通模锻技术需要对特殊的难变形合金进行多种成形.
  4. In the isothermal forging process, due to the uniform deformation temperature, 金属能保持相对均匀、精细的等轴晶组织. 因此产品具有屈服强度低、低频疲劳、高应力耐腐蚀等特点.
  5. The material utilization rate is high. 等温模锻的金属消耗比普通模锻低50%以上.

3 Categories of isothermal forging

  1. Isothermal precision die forging

在等温条件下锻造的金属,其锻件倾角小或无倾角,余量小或无余量. 该方法可以生产形状复杂、尺寸精度要求一般的结构件. 它也适用于高应力条件和形状接近零件的形状.

  1. Isothermal superplastic die forging

金属不仅在等温条件下表现出高塑性,而且在极低的变形速率(10-4/s)下也表现出高塑性。. 这是为了使不易变形的金属能够获得所需的冶金组织, shape, and size.

  1. Powder alloy isothermal forging

这种工艺方法采用粉末冶金作为原坯料进行等温锻造. 在等温超塑性条件下,坯料发生较大变形. 压实坯料,从而获得满足工艺要求的锻件.

适用于等温锻造的钢牌号是钛合金, superalloy, aluminum alloy, and magnesium alloy. The forgings are common in aerospace and aviation industries, 以及新材料难变形合金锻件的精密成形.

等温锻造技术不仅提高了金属材料的利用率,而且减少了后续加工余量的消耗和加工时间. It has high technical and economic benefits.
