摘要：

基于锻造操作机夹持热工件的实际工况，将钳口材料ZG310-570和HT350与几种常见的锻件材料组成摩擦副，通过对M-200摩擦磨损试验机进行改造，测试了各摩擦副在常温下的摩擦因数以及高温热试样块温度在降低过程中的各摩擦副间摩擦因数。试验分析表明，试样环ZG310-570与各材料间的摩擦因数小于试样环HT350与各材料间的摩擦因数；随着热试样块温度的降低各摩擦副间的摩擦因数增大。因此，在设计夹持装置时，钳口与热工件间的摩擦因数以热试样块高温下的摩擦因数来选取比较合理。

Based on the actual working condition that the forging manipulator clamping the thermal parts, the friction pairs were made by jaw material ZG310-570 or HT350 with other common materials. The friction coefficient of the friction pairs at normal temperature and in the process of the sample block temperature decrease were tested by the transformed M-200 type friction and wear tester. The experimental results show that the friction coefficients of the ZG310-570 pairs are smaller than that of the HT350 pairs and the friction coefficients increase with the decrease of the sample block temperature. Therefore, when designing of clamping apparatus, it is more reasonable to choose the friction coefficient between jaw and thermal parts according to the friction coefficient at high temperature.
