Automatic threading machine coupler thread coupler tapping machine DGS 40Z

 Introduction of automatic threading machine

 Shanghai Dirui DGS-40Z automatic threading machine is used for production of construction material rebar coupler, tapping thread in the rebar coupler. Our DGS-40Z automatic threading machine is newly researched and developed by our company, it's in vertical type,PLC controled and gear drive, with touch screen system.

In production, workers only need to put the coupler into the feeding channel, so it has a lower technical requirement for workers. Meanwhile, one worker can easily operate several machines, greatly saving up the labor cost, reducing labor intensity and improving production safety.It is the most ideal device for processing steel bar connection coupler so far.

Shanghai Dirui threading machine DGS-40Z  is used to produce Rebar Splicing Coupler, threading inside the rebar coupler. It can produce rebar coupler diameter 12-40mm, raw material can be carbon steel.

Besides, DGS-40Z tapping machine can process couplers with different screw pitches and different diameter, operators only need to change the screw tap and screw spindle. The operation is very simple.
