Steel bar straight thread rolling machine is a key equipment for rolling straight thread screw head of ribbed steel bar in construction engineering to realize steel bar straight thread connection. It can be clamped at one time to complete rib stripping and thread rolling. The reinforcement processed by the straight thread rolling machine can be closely and continuously connected with the straight thread metal fiber, and has good mechanical properties. The tensile strength can be increased by 20% - 30%, the fatigue strength can be increased by 40% - 60%, and the corrosion resistance can be increased by 50% - 200%. The connection strength and performance of the reinforcement processed by the straight thread rolling machine are higher than that of the reinforcement base metal, and the mechanical properties of the reinforcement joint meet and exceed the domestic and foreign standards.

The head structure of dbg-50 steel bar straight thread rolling machine produced by Shanghai Dirui Reinforcing Project Co., Ltd is innovatively designed. It adopts straight axis stepless cycle adjustment to effectively reduce the loss of rolling wheel. It has three points and one line, high concentricity and strong stability. The tooth shape of the processed thread is full and smooth. The added wire length reaches 120mm, which can almost meet the use of reinforcement mechanical connection engineering in all industrial and civil construction projects in China.
The reinforcement mechanical connection technology has high tensile strength, meets or exceeds the standard requirements of grade I joints in the national standard jgj107-2010, is not affected by rainy days, has simple operation, can connect a joint in one minute, and there is no open fire operation, reduces the fire risk, can be prefabricated in advance, shortens the construction period and greatly reduces the cost. It is a reinforcement mechanical connection technology vigorously promoted by the Ministry of construction at present.
Steel bar straight thread rolling machine Φ 12、 Φ 14、 Φ 1 6、 Φ 1 8、 Φ 20、 Φ 22、 Φ 25、 Φ 28、 Φ 32、 Φ 36. The HRB335, HRB400 and rrb400 ~ bars of medium 40 and other specifications can be rolled directly. Regular threads can be processed directly without pretreatment such as upsetting and rib stripping. The above is Shanghai Dirui's introduction to the types and uses of steel bar straight thread rolling machine, hoping to bring some convenience to users who buy this product.
