Definitions

  • the present invention relates to a pair of profile shears trained punching tool for making miter cuts in especially soft elastic material according to the generic term of claim 1.
  • a punching tool of this type is intended in particular for heating engineers make work easier when laying pipes to be insulated, in the special case when these pipes must be guided in a curve.
  • the insulation strips or full foam insulation strips for the pipelines are equally in order to always to ensure a constant thermal insulation.
  • the insulation strips or full foam insulation strips for the pipelines are already insulating strips with square recesses or lateral V-shaped incisions known (EP 0 748 988 A1); the insulating strips are relatively easy to do bend according to the route of the pipe.
  • the disadvantage of this known Conception is that due to the insulation strip of his cuts or recesses with regard to his proper function namely thermal insulation, is no longer fully effective.
  • the object underlying the present invention is in making a (hand) tool available to the heating technicians with which they only work on site and only in the required Make incisions in an insulating strip can (if this insulating strip is to be laid bent).
  • the support angle has grooves corresponding to the punching tool so that this punching tool can be immersed and the Cut safely up to the material edge.
  • the basic arrangement of the punching tool is such that a V-shaped wedge is cut out in a further embodiment has convex / concave shaped elements.
  • a straight insulating strip to run the conduits accordingly in a dimensionally stable curved insulating strip convict.
  • the geometric shape of these form elements very different configurations are possible.
  • Fig. 1 is designed in the manner of profile shears Punching tool 1 shown, which has two handling handles 2, 3, one with a material support table (anvil) 4 and the second of which is connected to a tool carrier 5. Will the two handling handles 2, 3 compressed relative to a joint 6, so the tool carrier 5 becomes against the material support table 4 pressed; lies on this one - indicated by dashed lines - Material strips 7, so the arrangement of the Punching tool punched a cutting contour accordingly.
  • the stamping tool 8 is designed such that that there is a V-shaped cut 9 (compare material support table 4) results. The corresponding to this V-shaped section 9 Element of the material strip 7 can then be pushed out become.
  • the present invention is based on knowledge and experience based on the fact that with very soft strips of material these do not define any Have an anchorage point relative to the punch and so under The incision may be too deep (or too little deep). In addition, it has been shown time and again that after cut the material strips on the punching tool remains and must be withdrawn, with the risk that the Strip breaks.
  • a contact angle 10 is provided on which the material strip 7 can be put on neatly.
  • this contact angle 10 are -
  • two grooves 11 are provided the tool 8 the material edge lying against the contact angle 10 really severed.
  • the contact bracket 10 also has two acting as a hold-down Thorns 12 open. Is the material strip 7 (as shown in Fig. 1) thin enough, so it becomes when opening the scissors Thorns 12 securely held back; the material strip is 7 thicker than the distance between the mandrels 12 and the material support table 4 corresponds, the material strip 7 is pressed against the mandrels 12, which penetrate into the material strip 7 until this abuts the contact bracket 10.
  • This provides a hand tool that can be used on site have the required miter cuts punched.
  • a material strip 7 is shown, the different Miter cuts have corresponding punchings a ... g, wherein the pairs of shaped elements are connected to each other are. Apart from the simple V-shaped wedge (compare a) all pairs form a positive and non-positive Connection. Regarding solution e, it should also be noted that the T-cut according to Fig. 2 (d) here in Fig. 3 by a trapezoidal cut is replaced.
