Definitions

  • the present invention relates to an apparatus for processing of locking ring bolts with gripping jaws for tightening of the bolt and a sleeve with anvil for cold forming the Locking ring (see e.g. US-A-3 695 086).
  • the bolt is inserted into a borehole, which is by two or more flat workpieces to be connected, for example Sheets, stretches and the locking ring is opened put the bolt on. Then the bolt is through the Device for processing the locking ring bolts tightened and the workpieces to be joined are thus firmly on top of one another pressed. With the further movement the locking ring molded into the locking grooves of the bolt, taking place a cold deformation, in which the locking ring at the same time the sleeve is cold formed with anvil. This is what happens Problem that after the processing of the Locking ring in the anvil is so 'caulked that one Restoring force of approx. 2 kN is required to release the caulk To release the locking ring from the anvil, and then with the Tool to be able to process the next locking ring bolt.
  • the object of the invention is achieved by such a device solved for processing locking ring bolts, at a support device is arranged next to the anvil protrudes beyond the anvil from the device and against the force of a spring element parallel to the longitudinal direction of the bolt is movable towards the device, and the force of the spring element is between 1.5 kN and 3 kN.
  • the support device formed as a sleeve arranged concentrically around the anvil is.
  • the spring element can preferably be a metallic coil spring or designed as a rubber or polyurethane spring element his.
  • a rubber or polyurethane spring can preferably be concentric to the anvil arranged rubber sleeve become.
  • the spring element of a concentric Sleeve is surrounded, which also serves as a guide serves for the support device. Doing so simultaneously the spring element is protected from environmental influences or the risk of injury by clamping in a metallic coil spring locked out.
  • the present invention is based on a prior art in which the devices for processing locking bolt systems very complex and heavy hydropneumatic Devices were designed with a special hydropneumatic Reset device had to be equipped around the processed locking ring, which is usually in the anvil has caulked out after completion of the processing loosen the anvil so that the processing device again could be removed.
  • the present invention offers a new solution, in the processing of locking bolts considerably is simplified and the processing is essential lighter and simpler devices can be performed.
  • devices can be processed according to the invention of broken mandrel rivets, which are very widespread, and are available much cheaper for processing can be converted from locking bolt systems.
  • 1 and 2 show such an invention for the Processing of locking bolt systems converted Dornbruchblindniet Meeting.
  • the present invention solves this problem in that the restoring force is increased.
  • Fig. 3 shows two sheets 20, 22 to be connected. These are provided with a drill hole running through both sheets. a locking ring bolt 24 is inserted into this borehole.
  • the locking ring bolt 24 has a head 26 which is similar a screw head can be formed.
  • the bolt 24 will with its end facing away from the head 26 through the bore Box Type.
  • the bolt 24 via locking grooves 28, preferably after Type of thread are formed.
  • This continues a predetermined breaking point 30 is removed from the head 26.
  • the gripping section 32 This is on its surface provided with grooves 34, which the transmission allow the corresponding tensile force on the bolt.
  • the invention is now Design of the processing device provided.
  • Figs. 1 and 2 is the invention Processing device for locking ring bolts from one Dornbruchblindniet réelle derived because these devices special light, simply constructed and thanks to large-scale production are inexpensive.
  • the illustrated embodiment is a device powered by compressed air.
  • the device has the usual gripping jaws 5, which is usually the mandrel of the broken mandrel rivet to grab.
  • the mouthpiece is for processing the locking ring bolt provided a different construction, the one with the union nut 6 like a mandrel broken blind rivet mouthpiece is placed on the processing device.
  • the inventive device for processing Locking bolt then has a sleeve on it, which concentrically around the gripping jaws 5 similar to the Dornbrüchblindniet-mouthpiece is arranged.
  • This sleeve opens in the anvil 2, which is used for cold forming the locking ring.
  • In front of this anvil 2 can be a holder 7 for the locking rings be provided if these are plugged directly with the setting tool should be.
  • An abutment ring 4 is arranged directly in front of the union nut 6, which is also a concentric guide sleeve 8 carries and at the same time for a concentrically arranged Spring element 3 serves as an abutment.
  • This spring element 3 can be used as a sleeve-shaped rubber or polyurethane spring or be designed as a metallic coil spring.
  • At the other end of the spring element is another sleeve attached, which concentrically surrounds the anvil 2, and over this forward, i.e. on the workpieces to be riveted protrudes.
  • This sleeve is in the sleeve 8 led that they are in the axial direction against the force of Spring element parallel to the longitudinal direction of the bolt can move behind.
  • This sleeve serves as a support device 1, and can be moved backwards until ends with anvil 2.
  • this support device 1 placed on the workpiece 22 in the state of FIG. 3. If, as shown in Fig. 4, the anvil 2 on the workpiece is moved, the supporting device 1 is guided in the sleeve 8 to the rear, i.e. into the processing device in, out, the spring element 3 being compressed.
  • the force of the spring element is chosen so that the Cold deformation of the locking ring is not yet hindered, but after tearing off the locking ring bolt at the predetermined breaking point 30 enough power is available to the anvil 2 from the locking ring 40 with the help of those stored in the spring element 3 Force to release.
  • the force of the spring element 3 is 1.5 to 3 kN.
  • the support device 1 does not of course have to be concentric Be formed sleeve. Also are, for example polygonal cross-sections or an openwork conceivable, where the support is only on some points on the workpiece 22 takes place.
