Reinforced straight thread rolling machine. Is the reinforcement end parts of a rapid direct roll made of thread, the wire first part of the cold hardening, and thus the strength is improved, so that the steel wire head and the base metal and other effects. This thread rolling machine can be processed Φ16mm ~ the Φ40mm the reinforced. Steel bar rib peeling thread rolling machine, transverse ribs and longitudinal ribs of the first reinforced peel cut processing, steel rolling the cylinder in front of the wire diameter to achieve the same size, then the thread rolling forming. This approach enables high precision threaded joint quality and stability, and the bar diameter and thread length, it is set to auto-reversing return from the workpiece, and shake to 0 when the automatic parking. Using the device within the coolant in the rolling machine, processing a specification reinforced, simply it is set rolling head, start a switch can be continuous processing of a large number of screw head, is compact, reliable performance, operation is very simple. greatly improve the work efficiency. Reinforced straight thread joint performance to meet the performance requirements of JGJ107-2003 "reinforced mechanical connection general technical procedures in Class I connector. HRB335 and 400 rolling straight threaded rebar splice detection by the State Construction Engineering Quality Supervision and Inspection Center, through 2 million cycles of load fatigue performance of experiments, in full compliance with the provisions of JGJ107-2003. Rolling machine construction speed, affordable, and have greater prospects for development.
