20230182242 · 2023-06-15 ·

A bolt setting method and device for a nail-shaped bolt with a head and a shaft, ending in a tapered manner. The bolt setting method includes: joining the bolt into a component with a deforming stroke during which the bolt reaches a first joining speed of ≤4 m/s and the shaft completely penetrates the components with a portion of a maximum diameter with respect to a shaft length, without a bottom side of the head abutting the at least one component, and after the deforming stroke, driving the bolt into the at least one component until a head abutment of the bottom side of the head on the at least one component by at least one friction stroke with which a frictional connection between the shaft and the components is overcome and with which the bolt reaches a second joining speed that is smaller than the first joining speed.

Hydraulic tool for a pulling and/or pressing device
