Definitions

  • the parts of the seal construction by flat (soft seals or metal-soft material seals) or Profile seals (soft seals or hard seals) to each other seal.
  • Expansion elements are also known that close in the closing opening introduced and in this to expand are brought, whereby a tight closure of the Opening is reached.
  • Expansion elements of the type mentioned above consist of a Sleeve and a pin guided in the sleeve.
  • the sleeve has the shape of a cylinder and is on the entire lateral surface provided with groove-like incisions, so that in Cut results in a jagged surface.
  • the inner surface of the Sleeve is flat and on the front side, from the head of the pen points away, provided with a circumferential bead.
  • the Pen consists of a shaft and a head made of one there is a widening cone, the slender area of the cone corresponds to the inner diameter of the sleeve. in the Area of the largest diameter is through the conical head ended a circumferential bead.
  • the length of the sleeve to Bead corresponds to the length of the head to the bead.
  • the first step is to seal the sleeve in which the head of the pen is in the starting position in the sealed hole introduced.
  • the outside diameter of the The sleeve corresponds approximately to the diameter of the bore (0 - 0.12 mm larger).
  • the conical Head by the action of a tensile force on the shaft Moved towards the bead of the sleeve, creating the braced Sleeve expands and extends with its grooved surface to the hole.
  • the head is moved so far until he puts on the bead of the sleeve or until the Bead of the head lies against the sleeve. After putting on on the beads there is an increase in force, which is the severing of the shaft from the head to the one in front of the head Has a predetermined breaking point.
  • This sealing plug system is very suitable, a tight one Closure of pressurized cavities to reach.
  • the high manufacturing technology is a disadvantage Effort and the high precision with which both the Sleeve as well as the pin and also the bore to be sealed are to be produced. This is reflected in the price of the sealing plug system out.
  • the use of this system is therefore relative expensive and its use in mass production has one significant influence on the unit price. This will continue System only for closures from a bore diameter of 4 mm offered. The system is for smaller diameters apparently not producible with reasonable effort.
  • plastic deformation e.g. by means of a plastic deformable plug made of aluminum
  • a plastic deformable plug made of aluminum is a tight closure a bore of a cavity under pressure possible.
  • the generation the plastic deformation resulting in the seal to achieve without loading the workpiece, which in particular intolerable for thin-walled and long workpieces Can cause deformation (bulging or buckling), that negatively affect their usability.
  • the invention has for its object a constructive and a technically simple solution for sealing propose boreholes under pressure, with which also provides a secure seal between the bore and the plug at high internal pressure.
  • FIG. 1 shows a workpiece 1 which has a bore 2, whose diameter tapers stepwise, the Area 2b the larger diameter compared to area 2a having.
  • a plug 3 is located in the area 2b of the bore 2 inserted from a plastically deformable material such as about aluminum can exist.
  • the diameter of the plug 3 is about 10% smaller than the diameter of the bore 2 in Area 2a and about 1.5 - 4.5% smaller than the diameter hole 2 in area 2b.
  • a firing pin 4 Before the stopper 3 is with a distance X a firing pin 4.
  • the diameter of the Firing pin 4 on its side facing the stopper 3 is about 80-90%, preferably 85%, of the diameter of the plug 3.
  • the firing pin 4 is in an element 5 slidably guided. In the starting position the Firing pin 4 by means of a spring 6, which is between a Collar 7 and a bearing 8 is arranged with the collar 7 pressed against a stop 9, whereby the distance x between Firing pin 4 and plug 3 are created.
  • the firing pin 4 partially protrudes through the stop 9. Before the end of the firing pin protruding through the stop 9 4 stands at a distance y a stamp 10, which is the end a piston rod 11 forms, at the other end a in a piston 12 guided piston 13 is arranged.
  • the Cylinder 12 is abruptly connected via a feed line 20 Compressed air supplied. In the starting position, the position the stamp 10 fixed by a stop 19.
  • the cylinder 12 is fixed to a slide 14, which in turn is arranged on a guide 15.
  • the carriage 14 is started by means of a spring 16 pressed against a stop 17.
  • the tension of the spring 16 can be changed by means of an adjusting nut 18.
  • Figure 2 shows a device according to the invention in the end position on average.
  • the device ensures that the kinetic energy of the Systems Piston - Piston Rod - Stamp on the Plug 3 acts, the impact is finely dosed.
  • the impact on the stopper 3 causes the stopper 3 partly flows into the area 2a of the bore 2 and in the Area 2a of hole 2 is placed intensively on the wall.
  • closures produced in this way withstand significantly higher pressures than Closures by slowly pushing the plugs in the hole is made.
  • the dosage of the impact effect ensures that the one required to create the tight seal Forming work is initiated in the stopper without it unwanted deformations of the workpiece to be locked comes.
