automatic u bolt making and nut assembly machine



1. One straight line feeding operation direction among multi-stations, such as chamfering, thread rolling, bending, nut assembly. This machine can save operators, working space and loading / un-loading time and create the best benefit.

2. Automatic Loading from the Bar/Stud Storage Tank, then Automatic Move to chamfer both ends at the same time from 1 clamping transferring operation.

3. Bar/Stud Loading and Bar Unloading automatically Clamping from middle of the steel rod supported, and both ends with a special design live clamping threading tools rotate drive. The steel rod no rotate, the threading tools rotate to cut.


Automatic Loading => Chamfering => Double heads Threading => Both ends nut assembling  => Bending => Automatic Unloading


1.We make the U Bolt Making Forming Machine (Full Automatic Production Line), Double end studs Making Forming Machine, SCREWS and Special-Purpose Hardware Processing Machines / Secondary process machine to Create a New Perspective for the Hardware Industry.

2. SPM for Auto Parts, Stud, Bolt, & Fastener

3. Automatic Movement System: to move the steel rod from Bar Storage Tank to Chamfering Station.

4. Processing Time: about 6~8 seconds/pc

5. Thread Size: M2~M20

6. 1~2 Operators.
