Principle and characteristics of rebar upsetting machine

By using the principle of hydraulic cold heading, the plastic deformation of the steel tip is increased, the diameter increases by 4~6mm, and then the thread is processed. The actual cross-sectional area after thread processing is greater than that of the original reinforcement section, which greatly improves the tensile strength of the joint. This upsetting thread joint is completely broken by the tensile test and is suitable for the higher requirements.
The steel upsetting machine adopts hydraulic technology, upsetting reinforcing bar, used for straight thread connection technology, and sleeve connection joint. The device is suitable for the upsetting straight thread reinforcement joints made of hot rolled ribbed steel bars with diameters of 16 ~ 40mmHRB335 (grade II steel) and HRB400 (grade III steel).
Equipment features:
(1) simple operation, hydraulic and electrical control, no professional technicians, and training for ten minutes.
(2) enlarge the sectional area of the steel bar by 15-20%, so that the base diameter of the thread is not less than that of the steel.
The diameter of the reinforced material is fully exerting the tensile strength.
(3) the production efficiency is high, each class can upend 300-500 heads.
(4) processing steel bar is wide, and can be machined in accordance with GB1499 or BS4449 (CS2) standard 12- 12- 40 specifications of reinforcement.
(5) equipment failure rate is small, no spare parts are easily damaged, and construction cost is at the bottom.
(6) environmental protection and safety, not affected by environment and climate.
