Definitions

  • the invention relates to a device for punching eyelets or the like.
  • Such a punching device is e.g. known from DE-GM 82 28 727. With this known device used in practice, it is possible to carry out mobile, i.e. on site to use eyelets in tarpaulins, e.g. in the tarpaulin of truck bodies.
  • a portable hydraulic system first drives an inner piston down via a first hydraulic line. This inner piston penetrates the entire system and has e.g. the cutting tool. This inner piston is surrounded approximately in the middle by an outer piston, which is actuated by a second hydraulic supply after the cutting process has ended and then moves the flanging tool, which surrounds the cutting tool, into the working position.
  • the object of the invention is to provide a solution which, on the one hand, makes a double hydraulic supply unnecessary while at the same time saving weight and overall height.
  • this object is achieved according to the invention in that the cylinder space of the outer piston can be filled via a single hydraulic supply and by a bypass the cylinder space of the inner piston for lowering the upper part of the tool onto the lower part of the tool, that of the cylinder head plate starting from the outer cylinder, a central feed and sealing tube is provided so that it is immersed in the cylinder space of the inner piston that the central feed and sealing tube is of such a length that the inner piston can be pushed back into its initial position if necessary and that a through line for returning Hydraulic fluid is provided under the sealing surface of the inner piston in the cylinder space.
  • the supply and sealing tube serves several functions, so it enables the filling of the inner cylinder space with hydraulic fluid, but it also serves as a sealant in a certain position of the outer piston and ensures the return of the hydraulic fluid located inside the cylinder space of the inner piston when the System from the lowered position.
  • the supply and sealing tube is connected to the single hydraulic supply via a bypass line provided with a regulated throttle valve.
  • the supply and sealing tube is provided in the region of its free end with a sealing surface which seals the cylinder head of the outer cylinder in the cutting position of the inner piston.
  • the invention also provides that the through-line in the head of the inner piston consists of a through-bore which leads below the sealing surface and is provided with a check valve, as well as a cross-bore, the inner surface of the cylinder chamber surrounding the head of the inner piston being made relative to the sealing surface of the head of the inner piston a sealing in a position releasing the head is (Fig. 5).
  • the upper tool part is designed as a riveting tool for riveting rivets arranged in the lower tool part after punching through the textile or plastic tarpaulin lying therebetween.
  • riveting tools an abundance of additional work can be carried out, which is required for plastic tarpaulins or the like.
  • it can also be useful to rivet strap staples, which are particularly required for customs closures on truck bodies.
  • belt staples which are usually formed from a base plate of the top plate with a staple and rivets
  • other elements can also be riveted, such as the buckle closures, so-called stripping or the like.
  • the invention also provides in a further embodiment that between the riveting tools a holding device, in particular a magnetic carrier, is provided for holding an element of a belt ramp or the like.
  • quick-action clamping devices are provided on the upper tool parts for fastening to the outer piston and / or inner piston.
  • the device generally designated 1
  • a single hydraulic supply line 6 can be removed as well as return springs 7 which raise the upper part of the tool back to the basic position after completion of the operation.
  • the double-piston drive unit 4, as shown in more detail in FIG. 2, is essential for the invention.
  • a first, outer piston 9 is sealingly guided in an approximately cup-shaped outer cylinder 8; the cylinder space of this piston 9 is designated by 10 in FIG. 2.
  • the piston 9 itself is in turn designed as a cylinder for a second, inner piston 11, the corresponding cylinder space is designated by 12.
  • the inner piston 11 is sealingly guided with a sealing surface 13 in a corresponding recess on the tool carrier 14, the latter being fastened in the lower region of the outer piston 9, screwed in the example shown.
  • An essential element for the invention is a sealing tube 16 which is screwed centrally in the cylinder head plate 15 of the outer cylinder 8 and has an inner through bore 17, which leads via a bypass line 19 acted upon by an adjustable throttle valve 18 into the cylinder space 10 of the outer cylinder 8.
  • the feed and sealing tube 16 has an upper tapered region 20 and a lower, thicker sealing region 21.
  • the narrower area 20 is selected in the dimension such that a sealing sleeve 23 introduced in the cylinder head 22 of the outer cylinder does not initially rest there, so that hydraulic fluid can get into the cylinder space 12 through the annular gap formed in this way.
  • the hydraulic supply is shown in FIG. 2 only as a corresponding bore and is designated by 24. In the upper starting position shown in FIG. 2, this hydraulic supply 24 initially acts on an annular space 25 in which the hydraulic fluid can get into the cylinder space 10.
  • FIG. 2 also shows a transverse bore 26 and a check valve 27 in the head of the inner piston 11 as well as through bores 28 in a sealing screw 29.
  • the mode of operation of the hydraulic drive unit 4 is as follows: The system is supplied with hydraulic fluid via the hydraulic supply line 6. It is initially in the position shown in FIG. 2 or FIG. 3, ie the Return springs 7 have raised the upper tool part 5. The hydraulic fluid supplied to the system via the supply nozzle 24 is first pressed into the cylinder space 10 via the annular space 25 between the outer wall and the outer piston 9, and also into the inner cylinder space 12 through the annular gap between the tapered area 20 of the inner supply and sealing tube 16.
  • the system has two significant advantages: practically no lubrication of the pistons is required, and on the other hand the cutting and pressing pressure can be regulated simply by adjusting the throttle valve.
  • FIG. 6 shows the possibility of using a double riveting tool 30 as the upper tool part and 30a as the lower tool part instead of the upper tool part consisting of punching tool 5a and flanging tool 5b.
  • the upper tool part 30 has two rivet punches 31, between which e.g. a magnetic carrier 32 is arranged.
  • the upper part 33 of a belt ramp can be held in position with this magnetic carrier 32.
  • the other element 34 of the rivet ramp is covered in lower tool parts 30a, rivet sleeves 35, which may be fastened thereon, point upward.
  • the open-top rivet sleeves 35 first penetrate the fabric web 36, penetrate corresponding holes in the upper belt part 33 and become then permanently riveted by the rivet dies 31.
  • riveting tools for so-called stripping, i.e. Buckle closures to be able to rivet u. Like. more.
