Definitions

  • the invention relates to an additional device for pneumatic nail feed of a compressed air-operated nail driving device with a cylinder in which a working piston is axially displaceably mounted, which carries a driver pin at the lower end, an expulsion channel formed at the lower end of the cylinder, in which the driver pin is guided and which is connected to a fastener magazine, a main control valve arranged at the upper end of the cylinder, a compressed air supply chamber separated from the working chamber of the cylinder by the main control valve and a cover closing the cylinder.
  • pneumatic driving tools work with an operating pressure of 6 to 8 bar.
  • the compressed air is admitted into a cylinder chamber by control valves, the working piston being axially displaced with a driver pin fastened to the bottom and a fastening means, such as e.g. a nail, a clip or the like. drives into a workpiece from the drive channel.
  • the fastening means preferably a nail
  • the fastening means lies in its entire length in the drive-out channel during one operation, the position of the nail to be driven in can be determined only with difficulty.
  • the nail can be driven through the sheet without holes being provided in the sheet.
  • sheet thicknesses of more than 2 mm the power of the working piston is not sufficient to drive the nail through the sheet into the workpiece. For this reason, holes are provided in the sheets through which the nail is driven into the workpiece.
  • driving tools are provided with an additional device which has the task of partially pushing the nail out of the driving channel. This allows the nail to be placed exactly on the specified attachment point of the workpieces (e.g. on holes in perforated plates) and driven into them.
  • Additional devices are already known, in the form of a compressed air cylinder arranged on the cover of the driving tool, the piston rod of which pulse the arm axially moves the piston and pushes the nail a little out of the expulsion channel.
  • additional devices limit the mode of operation of a portable and hand-held driving tool, since they exceed the limited size in any case.
  • the invention has for its object to provide an additional filing for pneumatic nail feed that does not significantly increase the size and weight of a portable and hand-held driving tool.
  • a pneumatic control system is installed in the cover, which axially advances the working piston up to an overflow upon actuation of a switching element and thus pushes the nail a bit out of the expulsion channel.
  • This control system preferably consists of a control piston which is arranged concentrically in the cover and which is provided with an axial bore which is connected to a compressed air reservoir in the operating position of the control piston.
  • control piston is expediently provided on its end face with a sealing ring which surrounds the mouth of the bore and which closes the exhaust air opening arranged in the main control valve when the control piston is in the operating position. This measure ensures that the working space of the cylinder comes into connection with the pressure fluid reservoir in the operating position of the control piston.
  • a check valve is expediently arranged in the overflow and can be actuated simultaneously with the control piston in the opening direction via a rocker. If the working piston has moved to overflow after actuation of the rocker, the compressed air can escape from the working chamber of the cylinder through the overflow and the working piston stops.
  • the compressed air required for pneumatic feed control is expediently taken directly from the driving tool.
  • the bore arranged in the control piston is aligned with the malfunction of the control piston with a supply line arranged in the cover, which leads into the compressed air supply space.
  • An adjustable throttle is expediently installed in the feed line in order to be able to set the feed speed of the working piston.
  • Fig. 1 shows a compressed air-operated nail device of conventional type.
  • This nail device consists of a trigger valve 1, a main control valve 2 and a cylinder 3, in which a working piston 4 designed as a differential piston is axially displaceably mounted, which is provided on the bottom with a driver pin 5.
  • the main control valve 2 is provided with an auxiliary piston 6, in which an axial exhaust air opening 22 is formed is.
  • a cover 7 is fastened above the main control valve 2.
  • This additional device consists of a control piston 8 which is mounted coaxially to the working piston and a ball check valve 9 (FIG. 2), both of which can be triggered by a mechanical rocker 10.
  • a helical spring 16 is supported on the cover 7 and on the control piston 8 in order to load it upwards into its rest position.
  • the control piston 8 is provided on its lower end face with a sealing ring 19.
  • the ball check valve 9 opening into the atmosphere is connected to the working space of the cylinder 3 via an overflow line 13.
  • a feed line 11 is formed, which opens into the compressed air storage space 20.
  • the control piston 8 is provided with a bore 12 which consists of a lower axial region and an upper radial region. The radial region of the bore 12 can be made to coincide with the feed line 11 formed in the cover 7.
  • the space between the auxiliary piston 6 and the control piston 8 communicates with the atmosphere via outlet openings 17 formed in the cover 7.
  • the driver pin 5 fastened to the working piston 4 is guided in an expulsion channel 14 in order to drive in a nail 15 which is fed laterally from a conventional nail magazine 21.
  • the nailing device provided with the above-described auxiliary device for pneumatic nail feed works as follows:
