摘要： A method for adjusting percussion pressure and a drilling machine. In the method the percussion power of a drilling machine is adjusted by moving a shank (2) in the longitudinal direction of the drilling machine forwards when a smaller percussion power is to be transferred from the percussion piston to the shank (2). The drilling machine comprises at least two groups of pistons (4a, 4b) moving in the axial direction of the drilling machine, the pistons being connected to act on the shank (2) by means of a pressure medium acting behind the pistons towards the front end of the drilling machine. The drilling machine comprises at least two separate groups of pistons (4a, 4b) whose travel with respect to one another is different and where pressure medium channels (7a, 7b) separate from one another lead to the cylinder spaces of both piston groups.

摘要： A pneumatic assembly (1) having combined approach and strike functions, and suitable for incorporation into a foundry core sand removal apparatus. The assembly comprises a barrel (1) comprising compressed air supply means (6, 7, 8) and pulsed air discharge means (25, 26); an approach cylinder (9) mounted in the barrel (2); a striking piston (11) mounted in the approach cylinder (9); a valve (13) and a valve housing (12) mounted above the approach cylinder (9) and communicating with the compressed air supply means (6, 7, 8); and a punch (23) rigidly connected to the end portion (9a) of the approach cylinder (9) projecting from the barrel (2). The pulsed air discharge means include a manifold (25) arranged to enable the mounting of a pulsed air discharge duct (26) and means (35, 36, 37, 38) provided thereon for analysing at least part (26b) of the pulsed air flow so that the output of the assembly (1) may be remotely controlled.

摘要： The impact velocity and impact frequency of the hammer piston of a percussion rock drill are varied in incremental steps in order to find the maximum penetration rate. The frequency and impact velocity are so varied that the impact power is kept substantially constant all the time. A micro-computer is used to control the process.

摘要： In a rock drill, the feed force is transmitted from the housing 11 of the rock drill to the drill stem or drill stem adapter 14 via a damping piston 17. The damping piston 17 rebounces by the reflected compressive shock waves and the rebounce is sensed and used to control a control pin 48 which adjusts the stroke length of the hammer piston 13 so that the reflected shock wave energy is minimized.
