Definitions

  • the invention relates to a device for deep drawing of sheet metal, consisting of a machine stand with a Machine table with a sheet holder arranged on it Sheet metal holder ring, an upper tool arranged above it with drawing ring and a drawing stamp that holds the machine table reaches through and during the pulling process in an upward stroke the sheet metal holder ring between sheet metal holder ring and Drawing ring clamped circuit board formed in the upper tool.
  • the invention has for its object a device of the structure mentioned at the beginning with an upwards working drawing stamp with regard to the constructive To simplify the effort and the movements.
  • the upper tool is designed as a shuttle and between the Forming position within the machine stand in which it is aligned with the punch and an ejector position outside the machine stand, in which the drawn part after is ejected below, is movable, and that loading with the boards either in the direction of movement the shuttle from the position opposite the ejector position Side of the machine stand or perpendicular to this direction of movement can take place.
  • Sheet metal holders remain in the device according to the invention and upper tool in position during deep drawing and only the drawing die is moved, you can see on the small stroke of the sheet metal holder.
  • the arrangement of the upper tool on a shuttle will Eject the deep-drawn part and thus the one with it linked movement sequence outside the machine stand relocated and can pull the deep-drawn part directly into an appropriate collection container or on a conveyor are thrown off, so that these movements inside the machine. It can also speed up the work cycle by during the Eject from the opposite side of the machine stand forth or perpendicular to the direction of movement the shuttle a new board for the next thermoforming process is loaded. By minimizing the movements the previous ones within the machine Safety devices and the necessary for this Controls are largely simplified, in part even dropped.
  • the ejector position can - depending on the spatial Conditions or loading options, as well as with Consideration of the tool change - on the side or behind the machine.
  • a particularly advantageous embodiment of the invention is characterized by the fact that the shuttle has two upper tools has, one of which is always in the forming position inside the machine stand, the other in one of two ejector positions on either side of the machine stand and both upper tools alternately are moved into the forming position, and that the Load with the boards transverse to the direction of movement of the Shuttle takes place.
  • the performance per Almost double the time unit of a deep-drawing device by one deep drawing and one ejection process can take place simultaneously.
  • Another acceleration can be achieved in that during the process the upper tools the device is loaded.
  • the forces can be easily within of the machine stand while guiding the shuttle only minor outside the machine stand Has to absorb forces that can easily be supported by a prop can be picked up on the machine stand.
  • the ejector position from top to bottom Ejector cylinder is provided on the shuttle guide attached and the guide with its ejector and reaches through the upper tool.
  • the ejector can eject Thermoformed part directly into one below Collection container, on a pallet or a conveyor be dropped.
  • Another preferred embodiment is distinguished characterized in that the device for forming a tandem arrangement a second device with the same structure Distance is assigned and the feeding of the boards from the space between the two devices and ejecting of the deep-drawn parts on those turned away from each other Side of the device is done.
  • the performance can be achieved with such a tandem arrangement double the device in the smallest space. You can also use both devices if necessary different deep-drawn parts manufactured at the same time become.
  • a single hydraulic unit can be used for the drive be provided.
  • the device has a machine stand 1, e.g. in Form of a welded construction, with an upper part 2 and a lower part 3.
  • a machine stand e.g. in Form of a welded construction
  • the piston rod 4 carries the punch 5.
  • the piston rod 4 is guided in a machine table 6, the is an integral part of the machine stand 1.
  • the sheet metal holder 7 rests with the Sheet metal holder ring 8, the pressure medium cylinder 9 in Machine table 1 is driven.
  • the guide 11 is in the upper part 2 of the machine stand 1 a shuttle 10 arranged to the outside of the Machine extends, the projecting part over a Support 12 supported on the upper part 2 of the machine stand 1 is.
  • the upper tool 13 is on the shuttle with the Drawing ring guided horizontally.
  • an ejector cylinder 14 arranged, the ejector rod 15 through the guide 11 is retractable into the tool 13.
  • the pressure medium cylinders 9 down the sheet metal holder 7, so that the upper tool 13 together with the deep-drawn part from the position shown in Figure 3 to the ejector position can be moved according to Figure 1.
  • the ejector cylinder 14 actuates and throws the ejector rod 15 the deep-drawn part 16 downwards.
  • a recording e.g. one container, one Pallet or a conveyor can be arranged, the Thermoformed part.
  • the device 1 to 3 designed as a tandem construction be.
  • the guide 11 projects above the machine stand 1 also to the other side and is too an ejector cylinder 14 is arranged there.
  • On the shuttle 10 are two top tools 13 next to each other with one Draw ring arranged and the shuttle runs over the forming station and both ejector positions, so that at the same time a deep-drawing stroke and an ejector stroke are carried out can be.
  • FIG 4 are two devices 20, 21 of the previously described construction arranged side by side, which in Alternate cycle work.
  • the integrated in the machine stand 1 Guideways 11 of the shuttle 10 run after opposite sides. From the space between the Devices 20, 21 alternate the boards corresponding to the arrows 22, 23 of that device fed, whose upper tool is just in the Ejector position is while the other device carries out the deep-drawing stroke at the same time.
  • the upper tools with the molded deep-drawn parts are followed by the shuttle along the guideways 11 opposite sides in the ejector position hazards.
  • the ejected deep-drawn parts are made accordingly the directional arrows 24, 25 transported away.
  • Hydraulic unit can be provided, for example in the foundation pit between the two devices and the hydraulic cylinder of the deep-drawing stamp both devices supplied.
