Definitions

  • the present invention relates to a powder-operated bolt-actuating device, in particular for use in hard-to-reach places, with a housing containing devices for receiving and guiding the bolts, for feeding the cartridges, for tensioning and releasing the device and at least securing the loaded and tensioned device, also with an approximately perpendicular to the setting direction handle handle with actuating means for triggering.
  • a wide variety of designs are known for powder-operated bolt-setting tools. Their mode of operation is similar to that of small arms. They are usually loaded individually with bolts, while the cartridges can also be fed in a magazine. The fuses are generally designed so that the device is released by pressing on the setting point. The clamping and the cartridge change can also be done via a pressure mechanism or by means of separate clamping and cartridge changing devices.
  • a special type of stud setting device is used for setting studs in hard-to-reach places, for example in pipes or when attaching heat-insulating plates in the head parts of molds.
  • These devices have one handle handle attached to the housing, which is provided with actuating means for triggering the bolt setter, so that the device can be inserted into the opening, can be pressed against the handle handle and the setting process can be triggered.
  • actuating means for triggering the bolt setter
  • the device according to the invention makes it possible for the user of the bolt-setting tool to tension the device by pressing in the mandrel and to change the cartridge after the setting process. Since the mandrel is essentially axially parallel to the handle of the handle and is located on the opposite side of the housing, this process can be carried out by simply placing the device; the user does not have to change hands, change hands or operate a separate lever. The handling of the device is thus easier, more convenient and more rational for the user.
  • sliding surfaces on the mandrel and percussion hammer are provided as actuators between the mandrel and percussion hammer, which are wedge-shaped on both devices, so that when the mandrel is pressed into the housing, the wedge surface of the mandrel meets the wedge surface of the percussion hammer and the latter clamped against the ignition spring.
  • a lever mechanism can be arranged as the actuating member between the mandrel and the hammer, so that when the mandrel is pressed in, it acts on a lever arm, while the other lever arm acts on the hammer against the ignition spring tension and tensions the hammer.
  • the present invention is not limited to these two preferred embodiments; rather, other actuators can also be used nete, known mechanical means, such as ball displacement or the like, curved sliding surfaces, etc. are used.
  • FIGS. 1 to 3 show only the parts essential for the clamping process in a schematic representation. The change of the cartridge is not shown.
  • 1 means the housing of the bolt-setting tool
  • 2 the attachment for the handle
  • 3 the trigger pin for the process of setting the bolt, which is located in the handle and can be actuated by means of the handle
  • 4 the bolt guide, which is mechanical with the hammer guide 5 connected is.
  • the percussion hammer 6 and the ignition spring 7 are arranged within the percussion hammer guide.
  • the percussion hammer guide 5 has a pressure spring 8, and a locking slide 9 under spring pressure is provided as a backup.
  • 10 is the mandrel, by the actuation of which the tensioning process takes place and which is connected to the tensioning slide 11.
  • the mandrel with the 1o Spannsehieber 11 is, as is apparent upon a consideration of Figures 1, 2 and 3, in the Ge - housing axially parallel to the stick handle against the spring pressure displaceable. Its wedge-shaped sliding surface slides over the surface-parallel sliding surface of the hammer 6 and tensions it against the ignition spring 7. After the actuation of the mandrel has ended, the mandrel slides back into its initial position by spring force, as shown in FIG. Figures 1 to 3 also show the various working stages of the device. In Figure 1, the device is shown in a relaxed, not pressed state, in Figure 2 in the status of the end of the tensioning process, in Figure 3 in a tensioned, pressed and ready for the triggering of the setting process.
