  • This invention relates to an apparatus for drawing wires and tubes, which employs ultrasonic vibrational energy. More particularly, the invention relates to an apparatus wherein the amount of vibrational energy can be varied depending upon the size and quality of the materials being drawn.
  • lt is the purpose, therefore, of the present invention to provide an apparatus for drawing tubes and wires using ultrasonic vibrational energy, without the foregoing disadvantages.
  • an apparatus in which an elongated energy transmitting device is provided with an axial bore.
  • the energy transmitting device is placed so that one end thereof abuts the feed end of a die so that material may be inserted into an aperture of the energy transmitting device and fed to the die.
  • the other end of the energy transmitting device is coupled to a device for generating vibrational energy and for changing the direction of the vibrational energy which comprises a plurality of resonance discs attached to the circumference of which are a plurality of vibrational energy devices. Energy is transmitted from the vibrational energy devices to the die through the feed device.
  • FIGURE is a longitudinal side sectional view illustrating the novel apparatus in accordance with the present invention.
  • the reference numeral 1 denotes a die holder, 2 a spacer, 3 a die load cell, 4 a die, 5 a spacer and 6 a vibrational energy transmission or feed element, respectively.
  • the tip portion of said transmission element 6 is attached to the die 4 by welding or other means such as a bolt and the like.
  • the reference numeral 8 denotes an element for changing the direction of vibration of the ultrasonic energy waves which is provided with a number of resonance discs 9 in a multistage fashion perpendicularly in the axial direction thereof, and the tip portion thereof is connected to the rear end portion of the vibration transmission element 6 by means of the bolt 7.
  • any suitable length and location for connection of the die 4, vibration transmission element 6 and element 8 for changing the direction of vibration may be selected so that they may be integrally actuated in a resonant state.
  • bolt 7 and element 8 for changing the direction of vibration identical diameter apertures 6a, 7a and 8a are provided. Tubes or wires to be drawn are fed through apertures 6a, 7a and 8a to the die 4 in the direction of the arrow 13 in the drawing.
  • the diameters of the apertures 6a, 7a and 8a are preferably determined in accordance with the outer diameter of tubes and wires to be drawn, and it is preferable that at least the diameters of the apertures 6a, 7a and 8a are larger than the diameter of the die 4 at the delivery side.
  • Each of the resonance discs 9 is formed into a polygonal shape and to each side thereof devices 10 for distributing vibrational energy are rigidly fixed by means of bolts and the like.
  • the resonance motion of the resonance discs 9 in a radial direction as shown with the arrow II is changed to the axial direction in the element 8 and is transmitted to the die 4 as the synthesized resonance vibration in the axial direction at the transmission element 6 as shown by the arrow I2.
  • tubes or wires to be drawn are continuously inserted through the open end of the aperture 321 of the element 8, fed into the die 4, and drawn from the outlet of the die 4 by powered means (not shown).
  • the synthesized vibrational energy to be transmitted to the die 4 can be freely selected by changing the number of the devices 10 for distributing vibrational energy fixed around the resonance discs 9 or by changing the number of the resonance discs 9. Therefore, it is possible to provide proper vibrational energy to the die 4 corresponding; to the material quality and the size of tubes or wires to be drawn. Furthermore, because the die 4 is connected to the element 8 for changing direction of vibration at the bolt portion 7, the change thereof is freely done.
  • Example Material Size before drawing Carbon steel tube Carbon steel wire As is clear from the above Example, the novel apparatus in accordance with the present invention considerably improves the drawing rate, reduction of area and the like, and is preferably but not exclusively directed to drawing metals and the like.
  • the novel apparatus for drawing wires and tubes in accordance with the present invention is so contrived that resonance discs are provided in a multi-stage fashion in perpendicular relationship to an element for changing the direction of ultra sonic vibration which is provided with an axial bore and a plurality of radial apertures to the bore and a plurality of devices for distributing vibrational energy are attached to the circumferences of the resonance discs, so that it is possible to provide a large amount of vibrational energy to the die.
  • the novel apparatus does not require a cooling apparatus and the like which is required when a number of devices for distributing large amounts of vibrational energy are fixed, and the space around the periphery of the die is not greatly restricted, thereby bringing about a very high efficiency. Further, it is possible to continuously feed tubes or wires to be drawn to the die through apertures, so that it is not necessary to move the apparatus each time when setting of tubes or wire to be drawn, further increasing efficiency. Moreover, the line from the element 8 to the die is in a resonant state, and there is no influence of a reflection wave or generation of transverse vibration, which further increases efficiency.
