Definitions

  • the invention relates to a punching device for incorporating a recess into a hollow profile at a predetermined distance from its abutting surface and is particularly useful for punching aluminum composite profiles for rung connections.
  • connecting elements for example rung connectors
  • connecting elements for example rung connectors
  • one of the profiles must be drilled in the end areas of the profile so that it can be screwed to the connecting element. Since known punching devices cannot be used for this due to their structural design, the bores to be provided at a predetermined distance from the abutting surface of the profile are machined into it by means of drilling machines. For this, a drilling template is placed on the profile and the hole is drilled of 'hand.
  • the object of the invention is therefore to provide a Stenz ⁇ or direction by means of which it is possible without difficulty and with simple handling to incorporate a recess into a hollow profile at a predetermined distance from its abutting surface in a short time.
  • the recess should be burr-free, so that reworking is not necessary.
  • the punching device should also be versatile.
  • a two-armed lever is pivotally mounted on a support which can be inserted into the hollow profile with a cutting plate and is articulated at one end to a cutting punch which cooperates with the cutting plate and is adjustable with respect to the latter, and the other end by one pneumatically operated servo device supported on the carrier is adjustable.
  • a fork-shaped intermediate member on the lever to provide which is rotatably mounted and preferably engages behind the cutting punch by means of a collar formed thereon.
  • the servo device can be formed from a piston which is inserted into a cylinder articulated to the carrier and can be acted upon by compressed air on both sides, the piston rod of which is articulated on the lever.
  • the carrier, the fork piece and / or the cutting plate should be provided with a recess which extends in their axial direction and which has a stop surface for the abutting surface of the profile which is arranged at a predetermined distance from the cutting stamp.
  • the carrier, the fork piece and / or the cutting plate on one or both outer sides with one or more guide surfaces for the hollow profile, the guide surfaces being provided with longitudinal grooves incorporated in the fork part and / or the carrier for webs molded onto the hollow profile can be formed.
  • a handle can be provided on the carrier between the cutting punch and the servo device, approximately in the center of gravity of the punching device, on which a pressure switch, which is inserted into the pressure medium supply lines of the servo device, is preferably attached to the face facing the cutting punch.
  • the punching device designed according to the invention is not only simple in its structural design and thus economical to produce, but also easy to handle and this makes it possible, above all, to incorporate a recess into a hollow profile in a short time without having to cut it Burr arises. If a two-armed lever is pivotably mounted on the carrier, via which a cutting punch interacting with a cutting plate can be actuated with the aid of a servo device, it is possible to insert the support of the cutting punch into the hollow profile and to have its abutting surface rest against a stop, so that a recess is to be machined into the hollow profile at a predetermined distance from this.
  • the hollow profile lies on it, it is not deformed, and there is no burr due to the narrowing of the recess. There is therefore no need for extensive reworking, rather the required recess has to be machined into the hollow profile in a very short time. And since the punching device designed according to the proposal has only a low weight and the cutting punch and the cutting plate can be adapted to the respective requirements without difficulty, there is a simple and versatile usability.
  • the punching device shown in FIG. 1 and designated 1 serves to incorporate a recess, for example a hole in a wall 3 of a hollow profile 2 of a heat-insulated composite profile, and essentially consists of a carrier 11 provided with a cutting plate 41, one of which can be removed by means of screws 19 bearing bracket 12 and a lever 13 pivotally held therein, one end 13 'of which acts on a cutting punch 14 and the other end 13 "of which can be actuated by a servo device 15. On the carrier 11 there is also a handle by means of struts 17 and 18 16 attached.
  • the servo device 15 is in this case formed from a cylinder 21 and a piston 22 which is inserted therein and can be acted upon by compressed air on both sides and to which pressure chambers 23 and 24 are assigned. Compressed air can alternately be supplied to the pressure chambers 23 or 24 from a pressure line 25 with the aid of a pressure switch 28 mounted on the end of the carrying handle 16 via pressure lines 26 or 27 connected to the handle.
  • the cylinder 15 is articulated on the carrier 11 by means of an integrally formed fork-shaped eye 29 and a hinge pin 30.
  • the piston 22 is also held at the end 13 ′′ of the lever 13, in which an eye 32 is formed on the piston rod 31 thereof and is mounted on a pivot pin 33 inserted into the lever 13. The pivoting movements of the lever 13 are thus balanced.
  • a recess 45 is incorporated into the bearing block 12, which has a stop surface 46 for the abutting surface of the hollow profile to be machined at a predetermined distance from the cutting punch 14.
  • the carrier 11 is provided with lateral guide surfaces 47 for the hollow profile 2
  • the bearing block 12 is provided with guide grooves 48 incorporated therein, into which webs 4 formed on the hollow profile 2 engage. Tilting of the hollow profile 2 during a stamping process is therefore largely excluded.
  • the pressure chamber 23 of the servo device 15 becomes closed Machining hollow profile attached punching device 1 supplied with compressed air, the end 13 "of the lever 13 are pivoted upwards and the end 13 'thereof downward about the hinge pin 34.
  • the force acting on the lever end 13" is corresponding to the distances between the hinge pin 34 and the hinge pin 32 and the pin 35 translated.
  • the cutting die 14 which is guided displaceably in the bearing block 12, since the lever end 13 acts on it via the pressure roller 36, a recess is punched burr-free into the hollow profile 2 in cooperation with the cutting plate 41 at a predetermined distance from the abutting surface 46 on the abutment surface 46 .
  • the punched-out part falls through a recess 43 of the cutting plate 41, which is exchangeably fastened to the carrier 11 by means of screws 42, and the slightly larger recess 44 of the carrier 11. If the pressure chamber 23 is then vented and the pressure chamber 24 is connected to the compressed air line 25 via the pressure switch 28, the piston 22 and the cutting die 14 which is inevitably connected to it via the lever 13 and the intermediate piece 38 are returned to the starting position, the punching device 1 can be removed from the processed hollow profile and another work process can be started.
