Three Die Three / Four Die Four Blow Bolt Forming Machine

Three die three / four die four blow bolt forming machine is an ideal machine for producing bolt-type fasteners. With a long stroke of the slider and the coordinated operation of various systems, it can produce large quantities of extra-long bolts in a short time.


Three die three / four die four blow bolt forming machine can achieve fully automatic production of nuts. Three die three / four die four blow bolt forming machine can cold forge bolts made of medium to low carbon alloy steel, such as m6-m40. Depending on the specifications of the bolts being produced, the production speed ranges from 50 pieces per minute to 300 pieces per minute. Equipped with a main shaft clutch, it consumes less power during normal operation.

Features of Three / Four Die Four Blow Bolt Forming Machine

  • Diagram of the Bolt Forming Process
  • Main Slider Section

    The slider is highly stable and precise, featuring a "horse-leg" design that can be adjusted up, down, left, and right. The main slider is cleverly connected to the rear wing, and the bottom is equipped with ultra-wear-resistant cast tin-copper plates. Automatic oil supply ensures the long-term operation of the machine's slider.


  • Clamping Table Parts

    A high-precision, multi-functional clamping unit that offers the choice between spring-type or pneumatic-type clamps. It enables the translation or flipping of parts.

  • Gear Mechanism

    The large feed gear and cutter gear are precisely machined. After the tooth surfaces are heat-treated, they are ground using an advanced gear grinding machine, ensuring perfect alignment between the cutting mechanism and the feeding mechanism.

  • Cutting Section

    The cutting part is driven by a slider linkage, with the crankshaft delivering consistent cutting force, ensuring clean and smooth cut surfaces.

  • Rear Support Section

    The ejection length at each station of the rear support can be individually adjusted via cams, and the cams can also be replaced to achieve trimming.

  • Feeding Part
    Imported equipment is used to process gears, which ensures gear accuracy and improves feed accuracy.


  • Clamp Movement Section

    Utilizes a conjugate cam clamp transmission mechanism, making the reciprocating motion of the clamp frame smoother and ensuring more stable high-speed operation.

  • Industries
