Definitions
- the present invention relates to a machine tool for cutting and / or forming plate-like workpieces, preferably sheets, comprising: a punching die for separating a workpiece part located in a machining position, in particular a deformed workpiece part from a resting on a support surface of the punching workpiece.
- the invention also relates to a method for discharging a particular shaped workpiece part from a punching die on a machine tool for cutting and / or forming plate-like workpieces, preferably sheets, comprising: separating the workpiece part located at a machining position from the workpiece resting on a support surface of the punching die ,
- a machine tool of the type mentioned in which the workpiece part of the processing position, preferably under gravity, with a rotational, tilting and / or linear movement in a discharge position on a formed on the punching die Ausschleusschräge can be moved along of which the workpiece part with a sliding movement preferably under gravity in a provided below the workpiece support and adjacent to the punching die Ausschleusposition can be brought.
- the workpiece part be firstly moved out of the machining position by a turning, tilting and / or linear movement into a discharge position on a discharge chamfer of the tool die in order to subsequently transfer the workpiece part with a sliding movement to a discharge position located next to the punching die.
- the workpiece part In the machining position, the workpiece part can in this case partially project beyond the bearing surface and after the free cutting, which is made at an opening in the bearing surface, execute a tilting movement about the edge. In this case, it is necessary that the workpiece part is positioned so that the center of gravity is arranged in the processing position not on the support surface, but over the Ausschleusschräge.
- a Abstanz simulation is formed between the edge and the Ausschleusschräge the punching die.
- the Abstanz simulation here typically runs at a right angle to the (horizontal) bearing surface.
- the workpiece part to be cut free from the remainder workpiece protrudes in the machining position over the support surface in the horizontal direction, i. the workpiece part is not in the processing position on the support surface.
- the workpiece part is separated from the remainder of the workpiece by the punch is lowered along the Abstanz scenes with a lifting movement, whereby the workpiece part is cut free from the rest of the workpiece resting on the support surface and lowered with a combined linear and rotary movement on the Ausschleusschräge.
- the support surface has at least one opening for engagement with a punch.
- the workpiece can be punched at the opening, eg to separate the workpiece from the remainder of the workpiece.
- the workpiece part which has been cut free at the opening can hereby be brought onto the support surface by this executing a tilting movement about an edge on the outer edge of the support surface, to which the discharge slant immediately adjoins.
- the punching die has a scraper surface in addition to the opening, it is possible to machine the workpiece at the opening by means of a punch with an off-center cutting edge with respect to the tool rotation axis, which can be positioned by rotation over the opening or over the scraper surface at the Abstanz notes the workpiece part to be separated from the remainder of the workpiece.
- the machine tool comprises a control unit for positioning the workpiece part in the machining position such that the center of gravity of the workpiece part is above the Ausschleusschräge. This ensures that the workpiece part performs a tilting or rotational movement about a provided on the edge of the support surface edge after the separating processing under gravity and thereby spent from the processing position to the discharge position.
- the machine tool additionally comprises a die receptacle in which the punching die is mounted, a punch receptacle in which a punch is mounted, and a drive unit, by means of which the punch receptacle and the die receptacle along a lifting axis are movable towards each other to edit the workpiece part in the machining position separating.
- the punching die is mounted in a die receptacle, which is moved along a lifting axis before or after the separating machining, until the discharge slope of the punching die joins a chute of the machine tool provided at the removal position.
- the die receptacle can already be arranged in the processing position so that the discharge slope adjoins the chute, but it is alternatively also possible to use the die receptacle only after the separating processing, i. while the workpiece part slides along the discharge slope, to move down so far that the lower edge of the Ausschleusschräge is positioned adjacent to the chute. This is particularly favorable for workpiece parts with large transformations to produce more space for discharging below the workpiece support or if a machining of the workpiece part above or below the workpiece level should be done.
- the workpiece is optionally punched at an opening in the bearing surface of the punching die or at a provided between an edge formed on the outer edge of the support surface and the Ausschleusschräge the punching die provided Abstanzisation.
- the punch and / or the punching die can be rotated about an axis of rotation to position the punch either over the opening or over the Abstanz imagery or the cutting edge. It is understood that a plurality of openings may be provided for engagement by the punch in the punching die.
- the punching die can be rotated relative to the punch in more than two different positions and fixed there, as in the DE 10 2006 049 044 the applicant, which is incorporated herein by reference for the purposes of this application.
- Fig. 2a shows a detailed view of the stored in the female receptacle 10 punching die 11 of Fig. 1 , on whose flat bearing surface 23 a deformed workpiece part 22 rests that of the in Fig. 1 shown workpiece 4 by punching processing along a formed in the support surface 23 opening 24 separated has been.
- punching die 11 has the problem that the separated, resting on the support surface 23 workpiece part 22 must be discharged by pushing, which can be done for example by means of a (not shown) scraper (eg in the form of a Eladurfeder) as a guide on the punch 9.
- a scraper eg in the form of a Eladurfeder
- the free-cut workpiece part 22 tilts under the action of gravity about a tilting edge 26 formed on the edge of the support surface 23 from the processing position B to a discharge position AB , in which the workpiece part 22 rests on the discharge slope 25 of the punching die 11, cf. Fig. 3b ,
- the Ausschleusschräge 25 is inclined relative to the support surface 23 of the punching die 11 and the workpiece plane 5 at a tilt angle ⁇ , which is approximately 45 ° in the present case.
- the workpiece part 22 subsequently slides under the action of gravity on the discharge slope 25 of the punching die 11 into a discharge position AS (see FIG. Fig. 3c ), In which the workpiece part 22 rests on an adjoining the Ausschleusschräge 25 rigid chute 27, at which the workpiece part 22 further slides along in order to be discharged from the machine tool. 1
- the support surface 23 of the punching die 11 is in the workpiece plane 5, to support the workpiece part 22 during the punching process.
- the die holder 10 is positioned by the punching processing below the workpiece plane 5, for which purpose the die holder 10 is typically lowered by approximately 30 mm with respect to the workpiece plane 5.
- the opening 24 can also be widened toward the center of the punching die 11 'in order to allow ejection of workpiece parts through the opening 24.
- the punch 9 and the punching die 11 ' may also be formed as a forming tool, by means of which in addition to the punching at the in the in Fig. 4a shown position a deformation can be made on the workpiece.
- the edge 26 for punching the workpiece may alternatively be arranged centrally on the punching die 11 '.
- the central cutting edge 9a of the punch 9 is lowered onto the punching die 11 'in order to punch the workpiece part at the cutting edge 26 or along the cutting surface 28.
- no opening is made in the support surface 23 of the punching die 11 ', since the rotation of the punch 9 or of the punching die 11' in this case does not open any additional processing options on the workpiece.
- Fig. 5b shows a further punching die 11 ", in which the Ausschleusschräge 25 is mounted below the opening 24 in the support surface 23.
- the punch 9 in this case has a cutting edge 9a, which can be brought into engagement with the opening 24 to one above the opening 24th In this case, the separated workpiece part is lowered in a combined linear and rotary movement onto the bearing surface 25. It is understood that in the right-hand sub-region of the bearing surface 23 there is an additional opening for the workpiece punching editing a workpiece can be introduced. It is further understood that for discharging large workpiece parts other than in Fig. 5b shown the Ausschleusschräge can extend over almost the entire cross-section of the punching die 11 ", in which case the support surface is formed by a narrow, for example, annular edge.
- the discharge is made possible with high process reliability, since the discharge position AS is located below the workpiece support and hooking of the workpiece part can be effectively prevented at the remainder workpiece in the discharge process described above.
