Description

  • The content of the German patent application DE 10 2011 087 084.9 is incorporated herein by reference.
  • The invention relates to a multiple tool for a punching device, in particular for a turret punch press.
  • Multiple tools or multiple punching tools, also called multitools, are well known for punching devices of the prior art. The multiple tools have multiple punches that gradually wear in the punch insert. The punches can generally be sanded to a certain extent in their stamped part in order to continue to use them.
  • The invention has for its object to provide a multiple tool for a punching device, which is very user-friendly and easy to maintain.
  • This object is achieved by the features specified in the claim 1. The essence of the invention is that the multiple tool has a mechanical punch length tester. With the punching length tester, the effective punching length of the punch is easy and fast verifiable. Further, separate tools are not required for this review. Under the effective punching length is understood here the punching length, which is required for punching the workpiece to be machined. The effective punching length is preferably slightly larger than the thickness of the workpiece to be machined.
  • In the guide body are preferably performed between 3 and 24 punches. For guiding the punches corresponding guides are provided in the guide body, which may be formed as a guide recesses. Conveniently, the punches are designed differently.
  • Further advantageous embodiments of the invention are specified in the subclaims.
  • The Prüffederelement according to claim 2 is preferably designed as a helical spring. But it can also be carried out for example as a plate spring, elastic material block or the like. The Prüfffederelement is preferably indirectly actuated by the punch to be tested. But it can also be actuated directly by the punch to be tested. By actuating the Prüffederelements changes its length and the Prüffederelement generates a spring force or restoring force acting on the punch to be tested and this moves back to its rest position. The test spring element can be designed as a test spring pressure element or Prüffederzugelement. In an embodiment as a test spring pressure element, the test spring element is compressed in the test insert and it generates a pressure force acting on the punch to be tested.
  • It is advantageous if exactly one Prüfffederelement is provided, which is arranged on the longitudinal center axis of the multiple tool. However, it is also possible to provide a plurality of test spring elements which are connected in parallel or in series.
  • The embodiment according to claim 3 enables a simple and uncomplicated operation of the Prüffederelements or the punch to be tested. Under the finger pressure is understood a pressure that can be applied for example by a machine user or machine operator with at least one of his fingers on the Prüfffederelement.
  • In claim 4, a preferred characteristic of the Prüffederelements is given.
  • According to claim 5, the Prüffederelement has a length which is variable by 3 mm to 40 mm, more preferably by 5 mm to 15 mm. It is advantageous if the length of the Prüfffederelements by 3 mm to 40 mm, more preferably by 5 mm to 15 mm, manually compressible by the finger pressure.
  • The bottom element according to claim 6 is preferably formed as a separate component which is fixed to the guide body. The arrangement according to claim 6 is extremely simple and reliable.
  • The embodiment according to claim 8 allows a secure transmission of the movement of the punch or the force applied to this force on the central part of the Prüffederelement. Preferably, the movement-transfer projection is designed as a web, more preferably as an annular web, which projects laterally at least in regions relative to the stamping body. The middle part is connected to the punch to be tested in, preferably direct, connection. Furthermore, the middle part in the test insert acts on the test spring element. The displacement of the punch to be tested is transferred to the middle part, so that this is also offset. The middle part is arranged and designed such that it through the various punch to be tested in the test is operable.
  • The punch fixing element according to claim 9 allows a local setting of the punch located in the rest position. When punch insert is preferably carried out only an actuation of the corresponding, intended for the punching punch. Further, the punch fixing element conveniently fixed in the test use the punches, which are currently not tested.
  • The test opening according to claim 9 allows a simple, manual displacement of the punch to be tested.
  • The gripping projection according to claim 10 is preferably provided on the punch-fixing element gripping bar, which holds the punches in their rest position. Preferably, the gripping projection then engages under the movement-transferring projection of the corresponding punches. It is advantageous if the gripping bar is designed in an annular manner.
  • The multiple tool according to claim 11 has essentially two main components. These are releasably connected to one another via a corresponding connection device. The driving device and the punch magazine are preferably screwed together.
  • It is expedient if a plurality of biasing spring elements are provided according to claim 12. All biasing spring elements together preferably have a biasing force of between 100 N and 10,000 N.

  • The driving pin body 15 also has an outer fixing shoulder 21, which also faces the driving head 13. At the fixing shoulder 21 is a stop ring 22, which runs around the drive bolt body 15. In the stop ring 22 sit a plurality of biasing springs 23. The biasing springs 23 are identical and preferably have an equal distance from each other. The biasing springs 23 are based on the bottom of the drive head 13 and the bottom of the stop ring 22 from. In the stop ring 22 a plurality of recesses 61 are formed, which are open to the punch magazine 11 out. In each recess 61 sits a pressure piece socket 24. In each pressure piece sleeve 24 in turn a spherical pressure piece 25 is displaceably guided, which protrudes towards the pressure piece bushing 24 and the stop ring 22 in the direction of the punch magazine 11 and by a compression spring 26 in the direction of the punch Magazine 11 is pressed. The stop ring 22 is movable in the direction of the drive head 13. Upon movement of the stop ring 22 in the direction of the drive head 13, the biasing springs 23 are compressed and exert a corresponding restoring force on the stop ring 22 with the pressure pieces 25.
  • The punch magazine 11 has a sleeve-like guide body 27 in which a plurality of punch guides 28 are provided. The guides 28 have an identical distance from one another and are arranged around the longitudinal center axis 12 around. They extend parallel to the longitudinal center axis 12. The guides 28 are each end open.
  • The guide body 27 has a connecting flange 29, which is arranged in the assembled state of the multiple tool 5 adjacent to the driving device 10. On the connecting flange 29, a locking ring 30 is provided with a plurality of Arretierausnehmungen 31. The Arretierausnehmungen 31 are associated with the pressure pieces 25 and have a corresponding complementary cross-sectional shape.
  • Opposite to the driving device 10, a stripping device 32 is arranged on the guide body 27, which forms a bottom element and the guide body 27 substantially closes there. The stripping device 32 comprises a plate-shaped central holding body 33, in which a plurality of receiving recesses 34 are formed. The receiving recesses 34 are arranged adjacent to the guides 28. In each receiving recess 34, a disc-like scraper element 35 is inserted, which in turn has a central passage opening 36.
  • Furthermore, the stripping device 32 has an intermediate plate 37, which is located between the holding body 33 and the guide body 27 and fixes the holding body 33 on the guide body 27.
  • On the holding body 33 sits inside the guide body 27, a cup-shaped receiving body 38 which has a central receiving recess 39. The receiving recess 39 is cylindrical and extends along the longitudinal center axis 12. The receiving body 38 is centrally inserted into the intermediate plate 37.
  • In the receiving recess 39 sits a Prüffeder 40 which projects on the side facing away from the holding body 33 from the receiving recess 39. The test spring 40 is designed as a helical compression spring, which is manually compressible by a finger pressure in the punching direction 9.
  • On the receiving body 38 remote from the end of the test spring 40 sits a coupling piece 41 which carries a central part 42. The middle part 42 is formed like a bush and is axially penetrated by the longitudinal central axis 12. The middle part 42 has a laterally outwardly extending middle part head 43, which is opposite to the receiving body 38.
  • In the guide body 27, a punch-fixing element 44 is inserted, which also in the FIGS. 5 and 6 is shown isolated. The punch-fixing element 44 extends from the connecting flange 29 in the direction of the stripping device 32. However, it ends at a distance from the stripping device 32. The punch-fixing element 44 has a bottom plate 45 which extends perpendicular to the longitudinal central axis 12 and from a central opening 46 is interspersed. From the bottom plate 45, an annular web 47 projects in the direction of the driving device 10. The annular web 47 runs around the opening 46. The bottom plate 45 is adjoined on the outside by a side wall 48. The side wall 48 jumps from the bottom plate 45 both in the direction of the stripping device 32 and in the direction on the locking ring 30 before. On the side wall 48, a gripping bar 49 is provided in the region projecting onto the stripping device 32, which protrudes from there inwardly from the side wall 48 inwards in the direction of the longitudinal central axis 12. The gripping bar 49 is arranged at a distance from the bottom plate 45.
  • In the bottom plate 45, a test opening 55 is further provided, which is arranged eccentrically to the longitudinal center axis 12 and so laterally to the opening 46. The test opening 55 has two opposite opening points 56, 57. The gripping web 49 is recessed in the region of the test opening 55.
  • In each guide 28, a punch 50 is arranged. Each punch 50 is elongated and substantially cylindrical. Each punch 50 has a punch body 54 to which a punching head 51 facing the driver 10 is provided. The punch head 51 have a larger transverse dimension compared to the punch body 54, so that each one of the stripping 32 facing movement transfer surface 52 is formed. The punch heads 51 thus form movement transfer protrusions.
  • Each punch 50 also has a punch portion 53 provided opposite to its punch head 51 on the punch body 54 and tapered with respect to the punch body 54. The punching punch part 53 essentially determines the effective punching length of the respective punching punch 50. The punching punch 50 preferably differ in their punching punch parts 53. The transverse dimensions of the punching punch parts 53 essentially correspond to the respective through openings 36. The punches 50 are guided in the guides 28 in and against the punching direction 9 axially displaceable.
  • Hereinafter, the multiple tool 5 will be described in detail in its assembled state for the punch insert.
  • For fixed connection of the drive device 10 and the punch magazine 11 is a connecting bushing 19 passing through the connecting screw 58, wherein the screw head 59 rests against the abutment shoulder 20. The connecting screw 58 has an elongated shaft 60 with an external thread, which is screwed into the central part 42. The connection bushing 19 passes through the opening 46 and bears against the annular web 47 on the inside.
  • The plungers engage in a latching manner into the locking recesses 31 of the locking ring 30, so that a relative pivoting movement about the longitudinal central axis 12 is prevented between the driving device 10 and the punch magazine 11. The pressure pieces 25 are pressed by the biasing springs 23 and the compression springs 26 in the Arretierausnehmungen 31.
  • The drive pin 16 passes through the test opening 55 and is arranged adjacent to the punch head 51 of the punch to be actuated 50.
  • The remaining punches 50 are fixed by the punch fixing element 44. The gripping bar 49 engages under the respective punch heads 51, so that the punch heads 51 rest on the gripper bar 49. These punches 50 are then in their inner rest position, in which they are completely arranged in the guide body 27 and do not protrude from the punch magazine 11.
  • When punching insert is then pushed over the actuating plunger 4 on the drive head 13, whereby the drive pin 16 is offset axially in the punching direction 9. The punching force is transmitted from the driving head 13 to the connecting bushing 19, which transmits the punching force with its head 18 via the retaining shoulder 17 on the drive bolt 16 comprehensive drive bolt body 15. By the drive pin 16 is then aligned with the drive pin 16 punching punch 50 axially guided in the punching direction 9 in its guide 28. The drive pin 16 penetrates the test opening 55. The punching part 53 of the offset punch 50 passes through the passage opening 36 and penetrates through the workpiece 8 into the die 7. The connecting bushing 19 also transmits the punching force centrally on the middle part 42 for the axial movement of the same. The centric power transmission prevents tilting of the central part 42.
  • The connecting sleeve 19 also transmits together with the connecting screw 58 after punching on the central part 42 a stripping force which is generated by the rebounding biasing springs 23.
  • By a relative pivoting movement between the driving device 10 and the punch magazine 11 about the longitudinal central axis 12, a different punch 50 can be locally offset by the driving pin 16. The plungers 25 hold the drive head 13 in a desired pivot position. They then engage with a detent into the locking recesses 31. The connection sleeve 19 also allows a pivoting movement of the drive device 10 and the punch magazine 11 to the Longitudinal central axis 12. The head 18 of the connecting bushing 19 is namely recorded with play in the driving device 10.
  • The test insert of the multiple tool 5, ie the testing of at least one punch 50, will be described in more detail below. For the driving device 10 and the punch magazine 11 are separated by loosening the connecting screw 58 from each other. The test opening 55 is aligned with the punch to be tested 50. Via the test opening 55, a machine operator or a test person exerts a finger pressure directed onto the stripping element 32 on the punch head 51 of the stamping punch 50 to be tested in such a way that the punch 50 to be tested is displaced axially in the punching direction 9. The punch to be tested 50 is like the other punches 50 in the punch magazine 11th
  • Since the middle part 42 rests with its middle part of the head 43 on the movement-transfer surface 52 of the punch head 51, and the middle part 42 is offset axially by the described coupling between the punch to be tested 50 and the middle part 42 in the punching direction 9 along the longitudinal central axis 12. The standing with the central part 42 in a fixed connection, preferably in screw connection, coupling piece 41 is moved accordingly. In this case, the test spring 40 is compressed in the punching direction 9. The test spring 40 is supported against the stripping device 32, which is attached to the guide body 27. The punching part 53 of the stamping punch 50 to be tested passes through the passage opening 36 of the associated stripping element 35 and then protrudes out of the passage opening 36 at the bottom. It is advantageous if the punching stamp part 53 then protrudes from the passage opening 36 by about 10 mm at the bottom. It can thus the effective punching length of the test Punch 50 to be tested or measured. The punch to be tested 50 is then in its disengaged test position ( Fig. 4 ). The compressed Prüfffeder 40 then pushes the tested punch 50 back to its rest position when the finger pressure is no longer exercised sufficiently or not at all.
  • The punch-fixing element 44 prevents that in the examination of a punch 50 and the other punches 50 are moved.
  • The connecting bushing 19 and the middle part 42 are guided axially displaceably in the driving device 10 or in the punch magazine 11 over a total guide length FGL. Each punch guide 28 has a longitudinal central axis 61. The longitudinal center axes 61 of the punch guides 28 lie on a diameter DS whose center is in turn on the longitudinal central axis 12 of the multiple tool 5. The diameter DS thus runs around the longitudinal center axis 12 of the multiple tool 5. Between the guide overall length FGL and the diameter DS is a guide ratio of guide total length FGL to diameter DS of 1.5 to 2.5, more preferably 1.7 to 2 , 2, before.
  • Each punch 50 is axially displaceable guided with its punch body 54 in the respective punch guide 28. Each punch guide 28 has a punch guide length FL and a punch guide transverse dimension FQ. In each case, there is a guide ratio of punch guide length FL to punch guide transverse dimension FQ of 2.2 to 4.2, more preferably 2.8 to 3.2 before.
  • Also, details of the illustrated embodiment may in itself constitute an invention or be part of an inventive subject matter. This relates in particular to the punch-fixing element 44 for fixing the punches 50 located in a rest position.
  • A corresponding multiple tool 5 for a punching device 1 then comprises a driving device 10 displaceable in the punching direction 9 with a driving head 13 for driving the driving device 10 through the punching device 1 and a driving body 16 in communication with the driving head 13. The multiple tool 5 then also has a drive The punching device 50 each have an effective punching length for punching a workpiece to be machined 8, wherein the driving body 16 in the punch insert each with one of the punching device 10 in connection punching magazine 11 with a guide body 27 and several guided in the guide body 27 punch punches Punch 50 cooperates to drive the same. Furthermore, the multiple tool 5 then has the punch fixing element 44 for fixing the punch located in a rest position 50. The punch fixing element 44 preferably has a gripping projection 49 which engages for fixing the punch to be fixed 50 in this.
