Detailed introduction
The hydraulic cold drawing machine can be used for the cold drawing of various low and medium carbon steel, low and medium carbon alloy steel pipes and bars, with a wide range of applications. Our company designed experimental devices at the beginning of the research and development of the cold drawing machine, conducted a large number of process experiments, mastered the basic laws of the cold drawing process, and the first complete machine was designed entirely by our company's technical personnel. In the long-term production practice of using the cold drawing machine to produce precision oil cylinder pipes for our own use, we have accumulated rich experience, both positive and negative, summarized many practical technical tips for the cold drawing process, and collected a large amount of relevant information from both domestic and international sources, forming a unique idea for the improvement of the cold drawing machine and the research and development of supporting equipment. Continuous improvements have been made in the reliability of the cold drawing machine, working stability, degree of automation, reduction of operator labor intensity, safety, and improvement of production efficiency, achieving tangible results. Our company, with a highly responsible attitude towards customers, aims for customers to achieve good economic and technical indicators as the ultimate goal, sincerely cooperates with customers, and works with high standards of scientific, rigorous, efficient, and innovative design, manufacturing, installation debugging, trial production, and lifelong after-sale service.
