Fully Automatic Bent Bolts Machine from Coil

Straight, cut, thread, bend. All-in-One Machine

From coil to completed product, the VAS machines are completely automatic machines and fully adjustable, allowing you to create limitless products on one machine. The machine will draw the coil, straighten it, cut it to the desired length, and thread it (one side or both), and bend it. 

The VAS line can perform a variety of operations, that include cold forming operations such as thread rolling, and material removing operations, such as drilling, pointing, etc.

The parts are automatically transferred inside the VAS machine from one station to the other, and the outcome is a finished part, that does not require any additional operations.

The following operations can be performed on the VAS machine in any sequence:

  • Chamfer Cutting (pointing)
  • Chamfer Rolling
  • Thread and Form Rolling
  • Knurling
  • Extrusion of the ends before thread rolling
  • Collaring
  • Heading
  • Grooving
  • Drilling
  • Stamping
  • Bending
  • Flattening

Samples of parts that can be made on the machine:

  • Straight Studs, with threads on one or both sides.
  • Hanger Bolts, with one side wood screw thread and one side machine thread.
  • U Bolts, Eye Bolts, Anchor Bolts.
  • Hooks and Eye Bolts with Wood Screw Threads.
  • Truck and Trailer U Bolts with chamfers.
  • Weld Studs and other studs, Chamfered, Stamped, and Fully Threaded.
  • Chain Links with chamfered ends and blanks for Fully Threaded Stainless-Steel Rods.
  • Bicycle shafts, Shafts for Children's Toys.
  • Extruded Studs for Engines, Extruded U Bolts.

The main advantage of the VAS line is the capacity to perform any number and any combination of operations in one machine. Each operation is done in a separate station, so a few operations take place at any given time, but in separate locations, to keep the high production rate. The separation of operations makes the machine very easy to operate and reduces the risk of one operation affecting the other. The flow of parts is done internally, with no external conveyors.  The finished parts eject from one side of the machine, at a rate of a minimum of 40-50 PPM (for chamfer cut parts) to 200 PPM, for rolled parts.
