The JS-185 Steel Bar Upsetting Machine offers a reliable and efficient solution for creating strong steel bar joints, ideal for projects with demanding strength requirements. With its user-friendly design, high tensile strength output, and ease of operation, it is a valuable asset for construction, rail, and power plant industries.




The primary function of this machine is to perform cold upsetting of steel bars, increasing their diameter by 4–6mm to improve the tensile strength of the joints, particularly after threading.
This machine is ideal for construction projects, road and bridge constructions, high-speed railways, and power stations, where high-strength steel bar connections are required.
The cold upsetting process increases the diameter of the steel bar ends, which significantly enhances the tensile strength of the joints, ensuring they are strong and durable.
The maximum working pressure of the JS-185 Steel Bar Upsetting Machine is 30 MPa.
The machine requires a voltage of 380V and has a motor power of 7.5 kW.
Yes, the machine is designed for ease of use and can be operated with minimal training, making it accessible for various operators.
The JS-185 Steel Bar Upsetting Machine can process rebar sizes ranging from 16mm to 32mm.
The recommended hydraulic oil for this machine is anti-wear oil with a viscosity of 68.
The machine dimensions are 1020mm x 500mm x 965mm, and it weighs 920 kg.
The machine utilizes advanced hydraulic and electrical systems to ensure high processing accuracy and reliable results in one operation.
Upset threaded joints created by this machine are strong and durable, often breaking in the base metal during tensile testing, ensuring long-lasting strength.
Regular maintenance is recommended to ensure optimal performance, including checking hydraulic oil levels and ensuring all components are functioning correctly.
Minimal training is required to operate the machine due to its user-friendly design, making it suitable for operators with basic machinery experience.
Yes, the machine is equipped with safety features to protect the operator and ensure safe operation during use.
You can purchase this machine through authorized distributors or manufacturers specializing in industrial machinery for construction.
