Upsetting Forged Rebar Coupler

Upsetting forged rebar coupler is made by a steel bar upsetting machine to upset the end of the steel bar, then use a special equipment such as a thread rolling machine or a threading machine to process the upsetting part on the thread, and then use the matching upsetting sleeve. It is mainly used for the connection of steel cages of bridges, high-speed railways, etc..




Upsetting forged rebar coupler features:

1. Upsetting forged rebar coupler is to upsetting the steel bar head and then rolling the wire, which enhances the strength of the steel bar joint and ensured the quality of the joint.


2. The upsetting forged rebar coupler is good for the connection of road bridges and high-speed railway steel cages, which is convenient for construction.


3. The Upsetting forged rebar coupler is produced and processed by No. 45 high-quality carbon steel, and the joint performance meets the performance requirements of the "I" level joint specified in the national standard JGJ107-2016.

1   Remove the  eccentric bushing  and eccentric shaft from the thread holder, loosen the screws first, and then use a special wrench for the eccentric bushing to rotate the eccentric bushing 180 degrees . Then, place the loosened screws into the screw hole after the rotation of 180 degrees and tighten them (the rolling head and rib stripping head are equipped with 3 eccentric bushing, each with a 180 degree rotation, and tighten them by changing the screw hole). 2 Install the threading roller and place it counterclockwise in 1-2-3  (POSITIVE THREAD)    Install the threading roller and place it anticlockwise in 3-2-1  (NEGATIVE THREAD) 3 Upper the rib stripping machine head, tighten the screws, adjust the test bar, and start working

Several Advantages of Using Straight Threaded Steel Bars

图片
1. The steel connecting sleeve is able to reduce the use of materials and easy to operate which not limited by the types of steel components. 2. The  straight threaded sleeve  can be connected conveniently, quickly and simply, they not need electricity in construction. 3. They can connect horizontal, vertical and oblique HRB335 and HRB400 steel bars of the same diameter or different diameter. The specifications and models of straight-threaded steel bar connection sleeves that our factory can produce are φ14-φ40 ordinary steel bar connection sleeves, adjustable steel bar connection sleeves, different diameter steel bar connection sleeves, and special steel bar connection sleeves. And provide wire rolling machine products of steel straight thread processing equipment.

Problems Encountered During Rebar Coupler Processing

图片
 Rebar coupler is also known as mechanical splices in the construction industry. The common specifications of the  rebar coupler  are M12, M14, M16, M18, M20, M22, M25, M28, M32, M36, and M40. The most commonly used specifications are M16, M18, M20, M22, M25, M28, and M32. These are the most used on the site, but also the most commonly used. Today, we will introduce to you how to solve the wrong diameter or length problems encountered in the processing of steel sleeves.  Causes:  1. The specifications of raw materials are not accurate, and the feeding speed is too slow. 2. Raw materials are bent and not straightened before processing. 3. The mechanical equipment malfunctioned, resulting in the diameter of the rebar coupler becoming smaller. 4. Operators do not process according to engineering drawings.   Solutions: 1. Adjust raw material specifications and models, and pre-feed appropriate amount. 2. Straighten the round bend steel before cutting the raw material. 3. Check the mechanica
