Abstract
A sound reduction device for use in a mechanical machining method or a joining method, in particular a pulse-type joining method. The sound reduction device comprises a clamping device by means of which at least one part to be machined can be clamped at a plurality of clamping locations, as well as a plurality of engagement components which engage the part surface at a number of engagement points, in order to damp vibrations of the part. The present disclosure also describes a joining method and a machining method in combination with the sound reduction device.
Claims24
A sound reduction device in combination with a setting device for use in a joining method, in particular in a pulse-like joining method or a high-speed bolt setting method, comprising the following features:
- a. a clamping device with which at least one part to be machined or a plurality of parts to be connected to each other can be clamped releasably at a plurality of clamping points between fastening components cooperating with each other, respectively,
- b. so that the joining is ensured, and wherein
- c. a number of engagement points with respective engagement components are provided by means of which the part is engageable at least on one side in at least a vibration-sensitive part portion so that a part vibration can be damped compared to a part vibration without engagement components.
The sound reduction device according to 2, by means of which the part can be engaged with 1 to 3 engagement components per standard area of 100 cm2 of the vibration-sensitive part portions.
(canceled)
A joining method using a setting device for joining at least a first part and a second part, in particular a pulse-like joining method, comprising the following steps:
- a. releasably fixing the at least two parts by means of a clamping device by means of which a plurality of parts to be connected are clamped at a plurality of clamping points between fastening components cooperating with each other, respectively, wherein the plurality of clamping points fastens the plurality of parts to a base, so that the joining of the parts is ensured, and
- b. at least one-sided engaging of at least one engagement component in at least a vibration-sensitive part portion of the at least two parts at at least one engagement point so that a part vibration can be damped compared to a part vibration without the engagement component, and
- c. joining the at least two parts by means of the setting device.
