Renewable Design for Straight Screw Rebar Coupler - Steel Bar Direct thread Rolling machine GGZL-40A3 – YIDA

1. Steel Bar Rib Peeling and threading machine BGZL-40A3

GGZL-40A3-type steel bar Direct thread Rolling machine is straight thread connection special steel rolling machine, mainly for the construction of steel processing. Straight thread reinforced joint is a new technology that uses straight thread to connect steel bar. It is a kind of mechanical reinforced joint which can withstand two kinds of forces. It is not reinforced by the pattern and carbon content of the restrictions, is conducive to poor solderability, and even does not allow welding of steel connections, with the same diameter, different diameter steel connection. Can be prefabricated, fast connection, good for neutral, simple process, safe and reliable, no fire operations, no environmental pollution, saving steel and energy, all-weather construction, a wide range of application prospects and obvious technical and economic and social benefits.

GGZL-40A3 Direct thread Rolling machine , can make the end of the steel straight thread forming, thread smooth standard, simple operation, reliable work. After use to the coolant device, the cooling effect is better. A kind of reinforced steel processing, rolling head only need to adjust once, so that the operating procedures greatly simplified, to overcome the general straight thread machine operation steps repeat the cumbersome drawbacks, than the average machine tool efficiency can be increased 2-3 times.

2).The Characteristics of the Usage

 3).The material of the splicing coupler

The material of the splicing coupler is constructional quality steel of No.45 steel.

Working Principle: 

1)Slice up the end of the rebar;

2)Peel the rib of the end of rebar with specialty rib peeling parallel thread rolling machine;

3)Connect the two ends of rebar with rib peeling thread coupler;
