专利汇可以提供Sonic energy metal working process专利检索,专利查询,专利分析的服务。并且Utilization of a resonant electromechanical transducer for delivering high power (energy to a nonresonant load surface, excited from a fixed frequency power supply. The application of the tool to the work surface is accomplished by a flat surface tool coupled perpendicular to the horn axis and parallel to the end surface of the transducer tip. The sonic energy is delivered to the workpiece by coupling only a small fraction of the total tool surface to the work surface. The velocity of the cutting surface of the tool relative to the workpiece is a function of the excitation level of the transducer; the velocity being independent of the average velocity by which the transducer is moved across the work surface. The rate of removal of material in a metal cutting, chip forming, or shaving operation is a function of the excitation and the depth of cut independent of the transducer-transfer-velocity; whereas, outside of certain limits the transducer-transfer-velocity is utilized to reduce the cutting rate of the tool.,下面是Sonic energy metal working process专利的具体信息内容。

1. A resonant horn structure electromechanical transducer comprising a loading mass having a first elongated structure of relatively fixed diameter, a force concentrator consisting of a second elongated structure of a lesser diameter, a piezoelectric driving means, and a clamping means; said driving means being positioned between one end face of each of said first and second elongated structures and defining a location of lower velocity, said clamping means consisting of a ring element engaging the said end faces; and the other end of said force concentrator elongated structure remote from said driving means defining a location of maximum velocity, said last named end having a flat surface in a plane perpendicular to the longitudinal axis of said force concentrator elongated structure; a tool having a flat surface, and means for fixedly positioning said flat surface of said tool parallel with the flat surface of said other end of said force concentrator elongated structure.
2. The transducer of claim 1 further comprising means for pulling said tool face across said work surface.
3. The transducer of claim 2 wherein said last-named means further includes means for applying a static force to said work surface.
4. The method of sonically removing metal from a flat work surface with a tool sonically vibrated by a resonant horn structure electromechanical transducer comprising: defining a location of maximum velocity, providing a flat surface at said location, positioning said flat surface in a plane perpendicular to the axis of said structure, providing said tool with a flat surface, positioning said flat surface of said tool parallel with said flat surface at said location of maximum velocity, contacting only a small fraction of said tool with a work surface and varying the angle between the flat tool surface and said work surface to thereby vary the depth of cut of said tool into said work surface.
5. The method of claim 4 further providing the step of pulling said tool across said work surface.
6. The method of claim 4 further providing applying a static force to said work surface.
7. The method of claim 6 wherein said step of applying static force includes applying said static force through a spring system.
