METHOD FOR CONNECTING A SURFACE-STRUCTURED WORKPIECE AND A PLASTIC WORKPIECE |
| 摘要 |
A method for connecting a surface-structured workpiece (SSW) and a plastic workpiece using a joining tool with a sonotrode. The method includes: positioning the SSW and the plastic workpiece on an anvil such that a structured contact surface section (SCSS) of the SSW faces a contact surface of the plastic workpiece; positioning the sonotrode in contact with an outer surface of the SSW that is opposite to the SCSS; and applying pressure to the sonotrode and/or the anvil perpendicular to the contact surface to hold the workpieces fixed between the anvil and the sonotrode and applying ultrasonic vibrations to the workpieces by the sonotrode for a predetermined period of time to induce softening of the plastic workpiece and penetrate pin-like elements of the SCSS into the plastic workpiece. |

1. A method for connecting a surface-structured workpiece and a plastic workpiece using a joining tool including a sonotrode, said surface-structured workpiece comprising a structured contact surface section, said structured contact surface section comprising pin-like elements extending away from the structured contact surface section, said method comprising:
positioning the surface-structured workpiece and the plastic workpiece on an anvil such that the structured contact surface section faces a contact surface of the plastic workpiece, positioning the joining tool on the surface-structured workpiece so as to bring the sonotrode into contact with an outer surface of the surface-structured workpiece, the outer surface being opposite to the structured contact surface section, and applying a pressure to the sonotrode and/or the anvil perpendicular to the contact surface to hold the workpieces fixed between the anvil and the sonotrode and applying ultrasonic vibrations to the workpieces by the sonotrode for a predetermined period of time, so that softening of the plastic workpiece is induced and the pin-like elements penetrate into the plastic workpiece. |
