Definitions

  • the invention relates to a for cutting workpieces cutting press formed from a film, which a press table with a ribbon running over it has that by two on each side of the press table arranged deflection rollers is guided all around and on which the film for making the cutouts by means of a cutting tool rests in the area of the press table.
  • Cutting presses of the above type are, for example used to cut soundproofing parts from bitumen foils, which on body parts of motor vehicles be glued. Usually have such cutting presses several cutting tools side by side.
  • the tape serves to transport the film under the cutting tools and for subsequent transportation. It usually consists of Rubber or a rubber-like plastic.
  • To cut out of the soundproofing parts cuts the respective cutting tool each during a short-term standstill of the tape through the film lying on the tape except for the tape. It cannot be avoided that with each cut, the one that supports the film Tape is at least slightly damaged. Similar to formerly formed by vehicles with spikes on road surfaces this leaves traces in the circulating band that are relative quickly lead so deep into the tape that it renews must become.
  • the invention is based on the problem of a To design a cutting press of the type mentioned at the beginning that your circulating clocked tape is as large as possible Has durability.
  • the belt can be used on the deflection rollers in very different ways shifted relative to the cutting tools become. There is particularly little construction effort Creation of the ability to move required if according to an advantageous development of the invention Means for moving the belt by means of a height adjustment a bearing of a deflecting roller are formed. With such a bearing height adjustment, that the belt moves by itself as it rotates shifted to one side.
  • Bearing height adjustment one that can be moved by a spindle Wedge, on which a bearing of the deflecting roller is supported is.
  • the band is made of steel.
  • Such one Band has a particularly long durability and leads to that the formation of punch burrs on the workpieces Deformation of the band is avoided.
  • Such a Punching burr can cause that when fitting the workpieces Material crumbles that when later painting the parts provided with the material interfere by impurities in the paint layer due to the material form.
  • using a steel band is more reliable to achieve that the workpieces during the cutting stroke be completely separated from the cutting grid.
  • the tape with belt cooling for cooling to below the dew point the surrounding air.
  • Belt cooling is basically with all cutting presses advantageous with a circumferential steel band, where the problem of undesirably strong adhesion of the cutting good exists.
  • the belt cooling could, for example, by a cooler can be realized via the below the press table returning run of the tape is performed. Especially the belt cooling is easy to implement, if according to another development of the invention Belt cooling is provided in one of the deflecting rollers.
  • Figure 1 shows a press table 1, over which a belt 2 made of steel, which is endless two trackless deflection rollers 3, 4 kept under tension is and can be set in a clocked orbital movement.
  • a band-shaped film 5 is made above the band 2 bituminous material represented by rollers 6, 7, 8 brought into contact with the band 2 from above becomes.
  • a cutting tool 9 moves from above into the film 5 except for the tape 2 and cuts a workpiece from the film 5.
  • the deflecting rollers 3, 4 are each supported by bearings 10, 11 stored on each side.
  • Bearing height adjustment 12 which is only on the bearing 11 is provided.
  • This bearing height adjustment 12 has one Wedge 13 on which the bearing 11 is supported.
  • the wedge 13 is by driving a spindle 14 by means of a Actuator 15 more or less in the horizontal direction to adjust. Because of its wedge surface, this will the bearing 11 more or less raised or lowered, which has the consequence that the band 2 from that shown in Figure 2 middle position more or less on the one hand or other side of the deflection rollers 3, 4 runs out, that is there is a transverse displacement of the belt 2.
  • a belt cooling 16 which is caused by a cooling medium flowed through tubes 17 is formed.
  • This belt cooling 16 is designed to cause condensation from Moisture comes from the air on the tape 2. Thereby the film 5 adheres less strongly to the tape 2.
  • FIG. 2 illustrates that the deflection rollers 3, 4 are longer are than the band 2 is wide.
  • the tape has 2 the opportunity to look through the effect of the height adjustment 12 sideways to one side or the other to move on the guide rollers 3, 4.
