Definitions

  • the invention relates to a punching machine with a feed device for the cyclical further movement of the material to be punched by the punching machine; with a series of tool elements, each having a die arranged in a die holder, a guide arranged at a distance above it for a punch and a punch; with a head plate of the drive device acting on the punch; and with the tool elements associated, switchable and disengageable coupling devices that serve the optional transfer of punching force to the assigned punch.
  • a punching machine is known from the magazine “Bands, sheets, tubes” (1976), pages 448 to 450, in which the tool elements, including punching stamps, are each C-shaped and individually fastened to the machine table. Coupling devices that can be switched on and off are not available. With each downward movement of the head plate under the action of the drive device of the punching machine, all of the punching dies provided are simultaneously moved toward the material to be punched and the dies, so that they all perform a (punching) cut at the same time.
  • the punching machine works according to the principle of the follow-up cut, in which the material to be punched is cycled through the punching machine between the punching strokes, a series of identical punchings or identical punching patterns being punched one after the other and a specific workpiece to be punched having several identical punchings or punching patterns one after the other .
  • a punching machine with a row of tool elements lying transversely to the feed direction of the material to be punched and coupling devices that can be switched on and off are known.
  • This machine has a common die plate for the dies and above it a common guide plate with bores in which the lower end regions of the punches slide up and down.
  • the punches are held in a die holding plate which is attached to the top plate of the punching machine.
  • no interchangeably inserted guide sleeves are provided in the guide plate.
  • the invention has for its object to provide a punching machine which can be converted more easily to other punched parts.
  • the punching machine according to the invention is universal and can also punch workpieces which have a total punching pattern which cannot be subdivided into identical individual punching patterns, particularly quickly and with high precision.
  • the guide sleeves with punch and the dies can be exchanged extremely easily or removed or inserted according to the respective punching task, and one or more punches can be switched off from a provided punch arrangement with each punch stroke so that he or she does not perform any punching.
  • the punching machine according to the invention can work according to the follow-up cutting principle or the complete cutting principle.
  • the individual cuts of the cut sequence can, if necessary, be carried out with punching dies switched on and off differently, which considerably expands the spectrum of parts which can be produced using the follow-up cutting principle.
  • the punching machine according to the invention also rationalizes punching according to the complete cutting principle, because with a single row of tool elements, each of which has a punch with an associated die, a larger number of different parts can be punched if one switches on and off other punch depending on the part to be punched , and because new tool sets can be put together quickly by simply replacing, removing or adding guide sleeves with punch and die nen.
  • part families are also significantly simplified, as will be explained in more detail below.
  • the cutting off of the respectively punched part from the material to be punched which is fed as a continuous band can also be integrated into the function of the punching machine according to the invention by providing a punching punch which acts as a severing punch and which is only switched on at the end of the sequence of the individual punchings.
  • the punching machine according to the invention can be built much lighter and smaller than conventional punching machines in terms of the installed drive power, since these had to be designed for maximum occupancy, i.e. use of the entire machine length in the direction of material movement for use of the punch and the resulting forces and required power.
  • the intermediate pieces of the coupling devices are preferably pneumatically, hydraulically, mechanically or electromagnetically displaceable.
  • the tool element assembly and / or the coupling device assembly can preferably be replaced as a whole.
  • a switchable coupling device is advantageously provided for each punch that can be switched on and off, although it is also possible to provide for punching dies to be switched on and off in groups. Conveniently, all punches of the punch arrangement provided can be switched on and off.
  • the invention further relates to a tool set for installation in an existing press; with matrices arranged in die mounts, with guides for punching dies arranged at a distance above it and with punching dies; and with coupling devices which can be switched on and off and which serve for the optional transfer of the punching force to the associated punch, characterized in that a number of the punching dies and dies are combined to form a structural unit in which a lower part extending over their length forms the receptacles for the dies and one over the length of which extends and arranged at a distance above the upper part forms a guide plate into which axially displaceable guide sleeves for the axially displaceable stamping dies are inserted; and that a number of coupling devices is also combined into a single unit.
  • the punching machine according to the invention is preferably electronically controlled, in particular CNC-controlled (computerized numerical control).
  • This control can take over the switching on and off of the individual punches or the drive of the individual punches and, if necessary, the feed device.
  • the control is advantageously carried out by means of an integrated, program-controlled computer, to which the data for the workpiece to be manufactured are fed.
  • the reaching of the top and bottom dead center of the punching stroke can be detected by sensors, the respective punch stamps being switched on after top dead center and being switched off after bottom dead center.
  • a check can be carried out, for example, by means of a sensor as to whether punching waste comes from all the punching dies that are switched on, the punching machine automatically switching off in the event of faults not noticeable by punching waste not occurring.
  • the punching machine according to the invention can be fully automated and, as a result, can also be operated without operating personnel, for example at night.
  • the control can be programmed, for example, using a keypad, punched tape or information carrier cassette.
  • the details of a tool element 42 and its punching force application can be seen more in detail from FIG.
  • the tool element 42 shown consists essentially of a die holder 24 arranged on the lower part 44 with as inserted tem cutting insert 26 trained die, a punching unit 48 inserted into the upper part 46 from above, which can be moved downwards against the action of springs 50 to the die, and a coupling device attached to the head plate 2 at the bottom.
  • the coupling device essentially consists of a vertical blind bore 54 which is open at the bottom and has a plunger 56 which is arranged to be vertically displaceable therein and serves to switch the plunger 56 on and off.
  • Below the cutting insert 26, an opening 40 is provided in the lower part and in the machine table 38 for removing the punching waste.
  • the individual punching dies 18 can be switched on and off as required by a CNC control. E.g. For each punch stroke, an identical recess can be punched next to the other, while certain holes in the workpiece, for example, are only punched once after a certain number of recesses and a separating cutting punch is actuated only once at the end of the workpiece with the punched row of recesses becomes.
  • the tool elements 42 or the punch 18 do not have to be arranged in a straight line, but the punch 18 can also be arranged behind and partly in front of the plane of the drawing, as viewed in the direction of FIG. 1. It is also possible to provide a plurality of switchable punching dies 18 in one plane transverse to the longitudinal extent of the punching machine. A group of a plurality of dies 26, stamping die units 48 and coupling devices can also be combined as a structural unit or tool set. It is also possible to attach a group of several coupling devices as a structural unit under the head plate 2, even if the dies 26 and punching units 48 are used individually.
  • the punch unit 48 is inserted in the simplest way from above into a corresponding hole in the upper part. The same applies to the die 26.
  • the tool elements 42 can be provided not only in one row in the longitudinal direction of the punching machine, but also in several rows one behind the other, as seen in the viewing direction of FIG. 1. A punching machine is thus in front of one another with the individual tool elements 42 or groups of tool elements 42 can be arranged at a selectable position on the punching machine, adapted to the particular punching task.
  • the tool elements 42 are also ideal for retrofitting existing punching machines.
  • a preferred embodiment for a punch unit 48 is shown in more detail.
  • An upper tool head 58, a lower guide sleeve 60 and a spring element 62 arranged therebetween can be seen.
  • a stamping punch holder 64, through which the actual punching punch 18 of smaller diameter is arranged, extends through a concentric inner space of these parts 58, 60, 62 that runs from top to bottom is attached.
  • the stamping stamp unit 48 is designed in a manner lubricated from the inside by an oil supply channel 66, the lubricating oil reaching down to the cutting stamp 18 and its passage through the lower end of the guide sleeve 60.
  • the die shown in Fig. 3 is a cutting insert in a so-called one-way version, which is therefore not re-sharpened when blunt but is replaced.
  • the cutting punch receptacle 24 has a receptacle cutout 70, which is circular but has a straightening 68, as seen from above.
  • the cutting insert 26 provided with a corresponding circumferential contour is inserted into this from above and fastened with small screws.
  • the cutting insert 26 contains the actual die cutting opening 28.
  • the straightening 68 ensures that the cutting insert 26 is in a precise position.
  • Fig. 4 shows a simple example of a so-called family of parts from the switch housing construction.
  • families of parts also of a much more complicated type, can be produced particularly efficiently with a punching machine designed according to the invention.
  • FIG. 4 a shows the simplest part of the family of parts, in which there are seven large punched recesses 72 arranged at an identical distance and a smaller punched recess 74 between them.
  • two punches 18 are provided in the longitudinal direction of the punching machine, one for punching a larger recess 72 and the other for punching a smaller recess 74. Both punches are actuated at the same time after the part 76 has been advanced by the feed length a.
  • a separating cutting punch could only be provided for separating the finished part 76 from the strip-shaped punching raw material, which is only switched on once after seven punching strokes.
  • the part 78 according to FIG. 4b) differs from the part 76 in that it has a shorter length and in that an elongated recess shape 74 'has to be punched in part of the smaller recesses 74.
  • an additional punch can be provided in the longitudinal direction of the punching machine, spaced apart from the two punch punches described above, which punches the extensions of the recesses 74 '.
  • This additional punch is to be controlled so that it does not perform the punching every time the punching machine is punched, but only where this is specified by the program control of the punching machine. Otherwise this additional punch remains switched off.
  • the separating cutting punch is to be controlled in such a way that after a part 78 with five recesses 72 it is cut off.
  • the part 80 according to 4c) differs from the parts 76 and 78 in that the larger recesses 72 have a smaller mutual center spacing a, the smaller recesses 74 "are smaller than before, and in some of the sheet metal tabs 72 holes 82 between the recesses are to be punched and that a special recess 84 with a different shape is to be punched at the beginning of part 80.
  • the procedure is the same as for part 76.
  • a separate punch is provided in each case, analogously to that described in connection with FIG. 4b) for the extension of the smaller recesses 74 '.
  • the additional punches are to be switched on in a controlled manner when a hole 82 or a recess 84 is to be punched.
  • FIG. 1 shows a top view of a turret plate 90 which can be used in the punching machine.
  • the turret plate 90 has an essentially octagonal shape with rounded corners and can be rotated in 90 ° or 45 ° sections about its vertical axis of rotation 92.
  • a total of 14 through bores 94 are distributed over the circumference of the turret plate 90 in such a way that at least some of the cut-off positions of the turret plate 90 have a plurality of bores 94 arranged along a straight line 96 in the longitudinal direction of the punching machine.
  • At a distance below the turret plate 90 is another, in Fiq. 5 invisible, similar revolver plate.
  • These two turret heads can be incremented together.
  • the lower turret plate rests on the machine table 38, but can rotate on it in a rotationally sliding manner when switching over.
  • the bores 94 serve to insert punching die units 48 in the same manner as shown in FIG. 2.
  • die receptacles 24 and dies 26 are arranged in the same places in the same way as shown in FIG. 2.
