Definitions

  • the present invention generally relates to a spiral steel bar forming apparatus and a spiral steel bar forming method. More particularly, the present invention relates to a spiral steel bar forming apparatus and a spiral steel bar forming method for forming spiral steel bars used in civil engineering field.
  • stirrups are tied to main steel bar individually and gradually.
  • spiral stirrups having intervals are increasingly weighted and used by the structure design engineers.
  • So-called spiral stirrups are spiral steel bars used with main steel bars, wherein a steel bar is bended into a continuous spiral to form the spiral steel bar.
  • the spiral stirrups are used for positioning the main steel bars and providing shear strength.
  • the cross-section of the spiral steel bar may be adjusted according to the practical design, commonly is in rectangular or circular shape.
  • spiral steel bars may also be used as main structure frames that provide structure strength in some special structure design.
  • Spiral steel bars are conventionally formed by a steel bar bender, which gradually bends a straight steel bar to a spiral steel bar without intervals. Subsequently a machine dissociates the front and rear of the spiral steel bar to generate intervals. The efficiency and interval control of the forming process are both improvable.
  • Debry Maurice FR-A-1 590 141 disclosed conventional mechanism for producing an indented bar (see preamble of claim 1).
  • This conventional mechanism includes bar driving device, a bending device and at least one helical ramp.
  • the bar driving device conveys a bar into the bending device, and the bending device rotates to bend the bar 180 degrees about an axis.
  • the bending device also compels the bended part of the bar to move along the helical ramp and therefore generate a deformation.
  • This conventional mechanism restricts the rotation angle of the bending device to accommodate the structure of the helical ramp.
  • the generated deformation of the bar is also fixed and not adjustable.
  • the spiral steel bar forming apparatus of the present invention comprises a bar bending device, a bar driving device and an interval generating device.

  • the spiral steel bar forming device further comprises a straightening device, a turning device, and a supporting device.
  • the straightening device is preferably disposed between the bar driving device and the bar bending device, wherein the straightening device straightens the steel bar before it enters the bar bending device.
  • the turning device includes a second axis and is disposed corresponding to an outside of the bar bending device. The turning device is turnable corresponding to the second axis and overturns the spiral steel bar in accordance with a movement of the bar bending device.
  • a supporting device is disposed abreast of the turning device. The supporting device supports the spiral steel bar overturned by the turning device.
  • the supporting device includes a spiral steel bar driving device.
  • the spiral steel bar driving device is movably disposed on the supporting device for driving the spiral steel bar toward the turning device.
  • the spiral steel bar driving device simultaneously drives the spiral steel bar toward the turning device in accordance with the driving of the steel bar.
  • the spiral steel bar forming method of the present invention comprises driving the steel bar, bending the steel bar in a predetermined position by using a bar bending device, and pushing the steel bar output from the bar bending device along the interval generating direction to generate an interval.
  • the driving of the steel bar is simultaneous in accordance with the driving of the formed spiral steel bar on the supporting device.
  • the bending step includes synchronously turning the formed spiral steel bar.
  • the present invention provides a spiral steel bar forming apparatus and a spiral steel bar forming method.
