Definitions

  • the invention relates to a device and a method for producing meandering heat sinks.
  • Heat sinks usually consist of a material with good thermal conductivity and often have a meandering shape to increase the heat-dissipating surface. Such heat sinks are currently made of die-cast aluminum. However, the production of such die-cast heat sinks is relatively slow, inflexible and expensive.
  • the device contains a first tool carrier, a second tool carrier that can be displaced relative to the first tool carrier via a drive in the direction of a travel axis, a holder arranged between the first tool carrier and the second tool carrier for guiding the sheet-like material, and a plurality of tools on the first and second tool carriers at right angles to the travel axis slidably guided folding tools, which are moved together when the second tool carrier is displaced in the direction of the first tool carrier at right angles to the axis of travel of the tool carrier.
  • the object of the invention is to provide a device and a method for producing meandering heat sinks that allow flexible and cost-effective production with high precision.
  • the device according to the invention contains a first tool carrier, one that can be displaced relative to the first tool carrier via a drive in the direction of a travel axis second tool carrier, a holder arranged between the first tool carrier and the second tool carrier for accommodating a blank and several bending punches which are guided on the first and second tool carrier so as to be displaceable at right angles to the traversing axis and which, when the second tool carrier is displaced in the direction of the first tool carrier, are activated by drives at right angles to the Traversing axis of the tool carrier are moved together.
  • meandering heat sinks can be produced flexibly, quickly and precisely from a printed circuit board cut from a strip material.
  • the circuit board separated from the metal strip for example, is folded together by the device in the manner of an accordion, with relative movements between the strip material and the bending stamps being avoided by the multi-axial movements of the bending stamps.
  • the simultaneity of all bending movements also enables a high production speed.
  • a wide variety of heat sinks can thus be manufactured in an effective and cost-effective manner with high productivity and great accuracy.
  • Between the first tool carrier and the second tool carrier are arranged two rails which can be moved relative to one another in the direction of the axis of travel of the second tool carrier and have holding devices which can be displaced on them at right angles to the axis of travel for holding the ends of the board. This allows the board ends to be gripped and moved to their end position on two axes.
  • the bending punches are arranged on tool slides which are displaceably guided on the tool carriers via guide rails that are parallel to one another.
  • Two tool slides, each with a bending punch, are expediently guided in a displaceable manner on the guide rails.
  • the tool slides are preferably displaced by the drives in such a way that they simultaneously move together when the second tool carrier moves in the direction of the first tool carrier.
  • the drives for shifting the tool slides, which are each guided displaceably on a guide rail can expediently be designed as a belt drive with an endless belt guided via a drive roller and a deflection roller, with one of the tool slides on an upper strand and the other tool slide on a lower strand of the endless belt is attached.
  • the tool slides which are movably guided on a guide rail, can be moved by a common motor.
  • the tool slides could also be moved along the guide rails by a chain drive, by individual drives or the like.
  • the holding devices can be formed by a counter-holder that is guided in a displaceable manner on one rail and a punching and holding stamp that is guided in a displaceable manner on the other rail.
  • the counterholder and the punching and holding punches can likewise be arranged on two tool carriages which are guided over guide rails and can be moved in relation to one another, in the same way as the bending punches.
  • a first processing module designed as a cutting and bending module and a second processing module designed as a bending module can be fastened to the holder arranged between the first tool carrier and the second tool carrier.
  • the method according to the invention is characterized in that the heat sink is bent from a circuit board in one working stroke by a plurality of bending punches that can be moved in two axes perpendicular to one another, and the ends of the circuit board are gripped by a holding device that can be moved in two axes that are perpendicular to one another and are moved to their end position.
  • the heat sink can be calibrated with its contact surfaces after bending by pressing against the bending die.
  • FIG. 1 and 2 is a device 1 for the production of an in figure 3 illustrated meandering heat sink 2 shown from a separated from a band material circuit board 3.
  • the device 1 has a first tool carrier 4 and a second tool carrier 6 which can be moved transversely thereto in the direction of a travel axis 5 .
  • the traversing axis 5 is designed as a vertical axis.
  • the in the figures 1 and 2 The first tool carrier 4 arranged at the bottom is stationary, while the second tool carrier 6 arranged at the top can be moved in the direction of the vertical travel axis 5 with the aid of a drive 7 . about in figure 1 recognizable guides 8, the second tool carrier 6 is slidably guided on a frame, not shown here.
  • the first tool carrier 4, which is designed to be stationary here, could also be moved in the direction of the travel axis 5 if required.
  • the two tool carriers 4 and 5 arranged vertically here could also be arranged horizontally and moved along a horizontal axis of travel.
  • a stationary rail-shaped holder 9 is arranged between the two plate-shaped tool carriers 4 and 6 .
  • a guide 10 for the strip material, a first processing module 11 embodied as a cutting and bending module, and a second processing module 12 embodied as a bending module are fastened to the rail-shaped holder 9 .
  • This first rail 13 can be displaced in the direction of the displacement axis 5 via a drive 14 .
  • Also arranged between the second tool carrier 6 and the rail-shaped holder 9 is a second rail 15 which is parallel to the holder 9 and can be displaced in relation to it.
  • the second rail 15 can be displaced in the direction of the displacement axis 5 via a drive 16 .
  • a plurality of bending punches 17 and 18 arranged next to one another are displaceably guided at right angles to the traversing axis 5.
  • the bending punches 17 and 18 are seated on tool slides 19 and 20, respectively, which are displaceably guided on mutually parallel guide rails 21 and 22, respectively.
  • four mutually parallel and horizontally extending guide rails 21 are attached to the first tool carrier 4 arranged below.
  • Four parallel and horizontally extending guide rails 22 are also provided on the second tool carrier 6 arranged at the top.
  • two tool carriages 19 and 20, respectively are displaceably guided for one bending punch 17 and 18, respectively.
  • the bending punches 17 and 18, which can be moved via the tool slides 19 and 20, are moved via drives 24 in such a way that they move together transversely to the travel axis 5 in the direction of the central bending punch 23 when the second tool carrier 6 moves towards the first tool carrier 4 in the lifting direction.
  • the bending punches 17 and 18, which can be moved via the tool slides 19 and 20, will also move apart again into their starting position.
  • the bending punches 17 and 18 guided on the tool carriages 19 and 20 therefore carry out controlled movements at right angles to the travel axis 5 of the second tool carrier 6 .
  • the two tool carriages 19 and 20 guided on the respective guide rails 21 and 22 of the first and second tool carriers 4 and 6 are simultaneously moved together or apart by the drives 24 together with the bending punches 17 and 18 attached thereto.
  • the drives 24 are designed as belt drives with an endless belt 27 guided over a drive roller 25 and a deflection roller 26 .
  • One of the tool slides 19 or 20 arranged on each guide rail 21 or 22 is fastened to the upper run of the endless belt 27 and the other tool slide 19 or 20 to the lower run of the endless belt 27, so that the two tool slides 19 or 20 upon rotation of the drive roller 25 in one Direction are moved together and moved apart when reversing the direction of rotation of the drive roller 25.
  • the drive rollers 25 are each fitted over an in figure 1 Motor 28 shown driven.
  • two tool slides 30 and 31 are also slidably guided on the first rail 13 and the second rail 15 on a respective guide rail 32 and 33, respectively.
  • the two tool slides 30 and 31 guided on the respective guide rails 32 and 33 are also moved in opposite directions via a drive 38 designed as a belt drive with a motor 34 and an endless belt 37 guided via a drive roller 35 and a deflection roller 36.
  • a drive 38 designed as a belt drive with a motor 34 and an endless belt 37 guided via a drive roller 35 and a deflection roller 36.
