The invention concerns an apparatus and a method for mechanically joining metal sheets, profiles and/or multi-sheet joints lying on top of each other, wherein joining tools are moved by power means towards the parts to be joined and a joint is made between the parts to be joined by the force effect of the joining tools. To make the joining tools easier to handle and widen the range of application for joints, it is proposed to reduce the reaction forces of the joining process by the fact that one joining tool applies the joining force to the joint at an exciting frequency which is above the characteristic frequency of the opposite joining tool, and the mounting of at least one joining tool is isolated from vibrations. The vibration isolation can also be arranged exclusively or in addition in the excited joining tool or the parts to be joined.
An apparatus for mechanically joining metal sheets, profiles and/or multi-sheet joints lying on top of each other, comprising a frame, joining tools arranged therein and power means for moving the joining tools;
An apparatus for mechanically joining metal sheets, profiles and/or multi-sheet joints lying on top of each other, the apparatus comprising a frame, joining tools arranged on the frame, a delivery mechanism for moving the joining tools toward each other, a percussion mechanism for exciting at least one of the joining tools, and a vibration-isolating means for keeping an exciting frequency at which the at least one excited joining tool can be excited, higher than a characteristic frequency of at least one joining tool located opposite the at least one excited joining tool.
An apparatus for mechanically joining metal sheets, profiles and/or multi-sheet joints lying on top of each other, comprising at least one guide housing, joining tools arranged therein, power means for moving at least one of the joining tools, and means for resiliently mounting at least one of the joining tools located opposite the joining tool moved by the power means and a vibration-isolating means for keeping an exciting frequency at which the at least one movable joining tool can be excited, higher than a characteristic frequency of the at least one resiliently mounted opposite joining tool.
