Definitions

  • the invention relates to a powder-operated bolt-actuating device with barrel, barrel mouth part and ignition device, wherein a tensioning plunger which is displaceable along the barrel axis is provided for tensioning the ignition device and which interacts with a displaceably mounted in the barrel mouth part, the end face of which protrudes in the relaxed position.
  • powder-operated bolt-setting tools have ignition devices which are only cocked when the bolt-setting tool is pressed sufficiently against a component.
  • devices are known in which the barrel is mounted displaceably and is displaced against the setting direction when pressed against the component, thereby tensioning the ignition device.
  • a bolt-setting device in which a tensioning plunger passing through the barrel mouth part is provided with the interposition of a tensioning plunger for tensioning the ignition device. Thanks to the small contact area of the tendon protruding from the end of the bolt guide part before the ignition device is tensioned, a specific support on the component and a high specific surface pressure are required to tension the ignition device.
  • the invention has for its object to provide a bolt-actuating device that takes into account the safety aspects relating to the tensioning of the ignition device on the one hand and on the other hand enables unimpeded use even in places that are difficult to access.
  • the object is achieved in that the barrel mouth part is rotatably mounted relative to the barrel about its axis and a sleeve which is displaceable along the barrel axis and whose one end face cooperates with the tension ram and the other end face cooperates with the probe member is arranged between the tensioning plunger and the feeler member.
  • the arrangement of the displaceable sleeve between the plunger and the feeler element ensures that the feeler element can be used in any rotational position of the barrel mouth part to move the tendon and thus the tension of the ignition device. So that one end of the sleeve always interacts with the clamping plunger and the other end with the feeler.
  • the above-mentioned requirements are met in particular when the end face of the sleeve facing the barrel opening part lies in the axial projection of the path which the feeler describes when rotating the barrel mouth part around the barrel axis.
  • the sleeve preferably surrounds the barrel concentrically.
  • the bolt gun has a housing 1 with a laterally projecting handle 1a.
  • a trigger 2 is mounted in the handle 1a.
  • a barrel 3 is slidably arranged in the front area of the housing 1.
  • a barrel mouth part 4 connects to barrel 3 on the front.
  • the axially immovable, rotatable about the axis of the barrel 3 holder of the barrel mouth part 4 serves a bolt 5. This sits in an opening 3a of the barrel 3 and is held by an annular spring 6 in engagement with an annular groove 4a of the barrel mouth part 4.
  • the locking of the barrel mouth part 4 in any rotational position is served by a locking bolt 7 seated in the barrel mouth part 4, which is pressed by a compression spring 8 against the locking recesses 3b having the front end face of the barrel 3.
  • a rod-shaped pushbutton 9 is slidably mounted, which alternately projects over the barrel mouth part 4 either to the front or to the rear.
  • the displaceability of the sensing element 9 is limited by a transverse pin 11 seated in the barrel mouth part 4, which protrudes into a groove 9a of the sensing element 9.
  • a sleeve 12 concentrically surrounding the barrel 3 between the barrel 3 and the housing 1 slidably mounted.
  • the front face ie the face on the setting direction, overlaps in axial projection with the rear face of the feeler element 9.
  • a driving piston 13 is slidably mounted in the barrel 3 and in the barrel mouth part 4, a driving piston 13 is slidably mounted.
  • a cartridge bearing 3d opens into the rear bore 3c receiving the driving piston 13.
  • the barrel 3 is supported in the ready-to-ignite position under contact pressure on a component 14 and bears on the back against a closure part 15 supported in the housing 1.
  • An ignition device 16 with an ignition pin 17, which is mounted displaceably in the closure part 15, and an ignition spring 18 is located in the rear housing area of the housing 1.
  • An arm 17a which projects laterally from the ignition pin 17, acts for tensioning the ignition device 16 with a slide that can be moved along the barrel axis , on the sleeve 12 upright ram 19 together.
  • the pushbutton 9 projecting beyond the barrel mouth part 4 in the rest position (FIG. 2) is first displaced in the barrel mouth part 4 against the setting direction.
  • the feeler element 9 transmits the displacement movement to the sleeve 12, which in turn displaces the tensioning plunger 19 against the setting direction against the force of the ignition spring 18.
  • the barrel mouth part 4, together with the pushbutton 9 is subsequently moved against the setting direction from the rest position shown in FIG. 2 to the ignition ready position shown in FIG. 1.
  • This displacement path is also transmitted for tensioning the ignition device 16 from the sensing element 9 via the sleeve 12 and the tensioning plunger 19.
  • the firing pin 17 By disengaging the arm 17a from the axial projection of the plunger 19, the firing pin 17 can be released to ignite a cartridge.
  • a spring 21 driving the plunger in the setting direction is provided for the renewed attack of the tensioning plunger 19 on the arm 17a of the ignition pin 17 which has moved in the setting direction for ignition.
  • the barrel mouth part 4 can be used together with the feeler element 9 in any rotational position relative to the barrel 3, since the feeler element 9 can always transmit the contact pressure to achieve the ignition-ready position on the annular end face of the sleeve 12.
