Publication number: 20060156776Abstract: A magnetic pulse forming process is performed by an apparatus and a method that causes the plasticity of a workpiece to be preliminarily increased to facilitate deformation to the desired shape. Initially, a mandrel having a surface and an electrically conductive member are provided. The workpiece is oriented between the surface of the mandrel and the electrically conductive member, and a first electrical current is caused to flow through the workpiece and the electrically conductive member so as to increase the plasticity of the workpiece. Then, a second electrical current is caused to flow through the electrically conductive member and the workpiece so as to cause to cause the workpiece to be deformed into engagement with the surface of the mandrel.Type: ApplicationFiled: December 19, 2005Publication date: July 20, 2006Inventor: Boris Yablochnikov

Publication number: 20060131300Abstract: A method of performing magnetic pulse welding operation to secure first and second metallic components together involves initially increasing the temperature of a first portion of the first metallic component to soften same without substantially increasing the temperature of and softening a second portion of the first metallic component adjacent to the first portion. Then, the first portion of the first metallic component is disposed in an axially overlapping manner relative to a portion of the second metallic component with a space therebetween. An inductor is provided relative to the axially overlapping portions of the first and second metallic components. The inductor is energized to deform the first portion of the first metallic component into engagement with the portion of the second metallic component so as to secure the first and second metallic components together.Type: ApplicationFiled: November 23, 2005Publication date: June 22, 2006Inventor: Boris Yablochnikov

Patent number: 7026585Abstract: The performance of a magnetic pulse forming or welding process is monitored by positioning a deformation member relative to an inductor coil of the apparatus, then energizing the inductor coil to exert a force thereon. The deformation member can be a plastically deformable tube, and the amount of such plastic deformation that occurs when the inductor coil is energized can be measured to determine the magnitude of the force that is generated by the inductor coil. Alternatively, the deformation member can be an elastically deformable body, and the amount of such elastic deformation that occurs when the inductor coil is energized can be measured to determine the magnitude of the force that is generated by the inductor coil.Type: GrantFiled: September 10, 2004Date of Patent: April 11, 2006Assignee: Torque-Traction Technologies, Inc.Inventors: Boris A.

Patent number: 7015435Abstract: A method for securing components of a vehicular driveshaft includes disposing a neck of an end fitting into the open end of a driveshaft tube. The end fitting is held with respect to the driveshaft tube so that an annular gap is formed between the neck and the driveshaft tube. An inductor is provided about the driveshaft tube adjacent the end receiving the neck. The inductor is energized to generate a magnetic field for collapsing the driveshaft tube about the neck at a high velocity so that the driveshaft tube and the end fitting are welded to each other.Type: GrantFiled: May 10, 2005Date of Patent: March 21, 2006Assignee: Torque-Traction Technologies, Inc.Inventor: Boris A.

Patent number: 6910617Abstract: A magnetic pulse welding operation is performed to secure first and second metallic components together, such as a yoke and a driveshaft tube in a vehicular driveshaft assembly. The yoke includes a first portion, such as a body portion, and a second portion, such as a pair of opposed yoke arms. The end of the driveshaft tube is disposed co-axially about the body portion of the yoke. An inductor axially is positioned co-axially about the overlapping portions of the end of the driveshaft tube and the body portion of the yoke. The inductor is energized to perform a magnetic pulse welding operation to secure the end of the driveshaft tube to the body portion of the yoke without generating a significant flow of air toward the inductor.Type: GrantFiled: March 5, 2003Date of Patent: June 28, 2005Assignee: Torque-Traction Technologies, Inc.Inventor: Boris A.

Patent number: 6908023Abstract: An apparatus for supporting a workpiece, such as a yoke having a body portion and a pair of opposed yoke arms, during a magnetic pulse welding operation includes a lower jaw, an upper jaw, and a support pin extending therebetween. During the magnetic pulse welding operation, the lower and upper jaws of the support apparatus engage the opposed yoke arms, and the support pin extends through respective openings formed through the opposed yoke arms. The support apparatus can also include a counter die that is disposed between the lower jaw and the upper jaw and has an arcuate recess formed therein that receives the outer portions of the opposed yoke arms therein. Lastly, the support apparatus can further include a pair of positioning rails that engage the body portion of the yoke. As a result, the support apparatus prevents deformation of the opposed yoke arms and absorbs shock waves that can be propagated through the yoke during the magnetic pulse welding operation.Type: GrantFiled: March 5, 2003Date of Patent: June 21, 2005Assignee: Torque-Traction Technologies, Inc.Inventor: Boris A.

Patent number: 6892929Abstract: A magnetic pulse welding operation is performed to secure first and second metallic components together, such as a yoke and a driveshaft tube in a vehicular driveshaft assembly. The yoke includes a first portion, such as a body portion, and a second portion, such as a pair of opposed yoke arms, that are separated by a bridge portion. The end of the driveshaft tube is disposed co-axially about the body portion of the yoke, and a magnetic pulse welding operation is performed to secure the end of the driveshaft tube to the body portion of the yoke. The bridge portion can be defined by a groove formed in either the outer surface or the inner surface of the yoke. The groove may have side portions that extend either generally perpendicular or are angled or tapered relative to an axis of rotation of the yoke. If desired, a pair of opposed, semi-circular grooves may be formed in the yoke to define the bridge portion.Type: GrantFiled: March 5, 2003Date of Patent: May 17, 2005Assignee: Torque-Traction Technologies, Inc.Inventor: Boris A.
