Embodiment Construction

[0020] According to Fig. 1, the pin installer 1 pushed by the explosive force schematically has a mounting piston 4 that is pushed by the expanding gas of the propellant cartridge in the combustion chamber 2 and performs limited axial movement in a guide cylinder 3 to make A pin 5 arranged along the axial direction is nailed into the base body 6 until the bottom dead center uTP of the movement or the corresponding installation depth T, and also has an electromechanical adjustment circuit I indicated by a thick line. An electronic adjustment device 7 in the form of a microcontroller with an integrated counter n and timer t, a rotatably adjustable setpoint generator 8 for the installation depth T, and a position measuring sensor 9 arranged in the guide cylinder 3 , A control device 10 in the form of a discharge valve sleeve that can be moved electronically and mechanically as a mechanical actuator that can be controlled electrically and an operating switch 11 are controllably connec...

Abstract

The invention relates to a pin mounting device (1), having a mounting piston (4) impelled by the inflatable combustible gas in the combustion chamber (2) and driving a pin (5) in the base body (6) in a single propelling process and a mounting depth adjusting device, in which an adjusting circuit (I) is provided with an electron adjusting device (7), a rated value generator (8) for the mounting depth (T), a position-determining sensor (9) for determining a position of a lower dead point (uTP) of movement of the mounting piston (4), and a control device (10) for an automatic adjustment of a motion energy of the mounting piston (4) for the next propelling process; and in the adjusting method the electron adjusting device (7) can find out the adjusting amount for altering a motion energy of the mounting piston (4) for the control device (10) based on the rated value of the mounting depth (T) for next mounting process and the position of the lower dead point (uTP) of movement, and temporarily as the adjusting amount for the next mounting process which is intermediate stored.

Description

Technical field [0001] The invention relates to a bolt installer (Bolzensetzgeraet) with an installation depth adjustment device and a matching adjustment method. Background technique [0002] In the pin installer, the installation piston is accelerated in a one-time propulsion process usually formed by the explosion of the propellant cartridge or the combustion of the mixed gas in the combustion chamber, and it drives the pin into the base with its kinetic energy. The kinetic energy is pre-determined according to the hardness of the substrate and the desired installation depth through the composition of the propellant cartridge or mixed gas, the change in the volume of the combustion chamber, and the selection of the starting position for the installation of the piston and the damping element. This usually requires time-consuming and material-consuming preliminary trials. [0003] According to DE 3930592 A1, there is known a gunpowder propelling pin installer with a mounting pis...
