With the continuous development of the oil industry,the demand for sucker rod is becoming larger.According to the theoretic analysis and the experimental investigation,this paper designs a new type of sucker rod and puts forward a upsetting process for the Φ28.5mm sucker rod in order to meet the needs of the oil industry for the sucker rod.At the same time,a set of high accuracy dies with simple structure and long service life is designed.This new sucker rod requires less material and is convenient to be installed.The advantage of the production process of the new type of sucker rod has been verified that it is of high material utilization ratio and production efficiency as well as high accuracy.The social and economical efficiency is remarkable.For this reason,the method is a profitable reference for producing the new type of sucker rod in batch production.
