Changsha DLADTO Rebar Splice Co., Ltd

  Upsetting forged threading rolling machine : (1) It is used to connect the steel cages on bridges. (2) This machine adopts double hydraulic cylinders for clamping and upsetting with stable performance and high efficiency. (3) Upsetting of 16~32 steel bars, it is not need to replace the impact head, the mold is durable and has a long life. (4) The weight of machine is 1000 kg, the material is affordable with large pressure and the forming rate of the steel bar head is high. It is an ideal product for upsetting straight thread connection. Changsha DLADTO Rebar Splice Co., Ltd  is a professional rebar coupler producer, we have been in this field for a long time with customers for all over the world.

Features of   grade 4 steel rebar coupler : 1. Taking international No. 45 steel with special manufacturing process. They have high dimensional accuracy and reliable quality. 2. Grade 4 steel rebar coupler is able to connect HRB500 ribbed steel bars of Ф16-Ф32mm. 3. Grade 4 steel rebar coupler are tested by the National Construction Engineering Quality Supervision and Inspection Center, it has reached the I-level joint standard in JGJ107-2016. 4. It has three series of standard type: positive and negative thread type and transition thread type, which can meet the horizontal, vertical and oblique directions of industrial and civil construction, water conservancy, power station, bridge, tunnel, subway and other building structures. The requirements for connecting steel bars of the same diameter, different diameter and adjustable length and direction in other parts.

Both straight thread rebar coupler and   cold extrusion rebar coupler   are steel mechanical connection. The cold extrusion rebar coupler is deformation connection after the sleeve is extruded, and it bite the steel bar through cold plastic deformation to form a plum-blossom toothed sleeve cold-pressed joint. Its strength exceeds that of the base metal. And the reliability and plasticity are better than electric welded joints. Advantages (1) The performance of the joint is reliable and it is less affected by environmental and human operating factors. (2) The operation is simple and easy, and the opertator can take up the operation after fast training. (3) The speed of deformation connection is 3 to 5 times faster than electric welding and it takes only 3 minutes to connect a 32 joint.
