The company developed the production of GYL-40A-type thread rolling bar reinforcement end machine is to fast and direct rolling into parts of a thread, the first part of the silk produced work hardening, so that the strength was increased, first to make steel wire mother the effect of such strong material. The machine can process φ16-φ40mm of steel. Reinforced straight thread joint performance to meet JGJ107-2003 "General technical specification for steel mechanical connection" I-level joint performance requirements, in full compliance with the provisions of JGJ107-2003. 
 GYL-40B-type rolling bar rolling straight screw thread machine is a newly developed process connected straight thread steel wire head and a dedicated machine. On the original machine tools to improve and enhance, in the case of replacing a few parts, the machine can achieve φ16-φ40mm nine kinds of specifications directly rolled steel, part of the cutting rib rolling, rolling three processes cutting method of processing steel wire head. Reinforced straight thread connector performance to JGJ107-2003 "General technical specification for steel mechanical connection" in the I-level connector requirements. 
 Composition: 
 Rolling machine consists of frame, clamping mechanism, the feed carriage, reducer and rolling head, cooling system, electrical system integration component.
