Definitions

the present invention relates to a punching and embossing machine according to the preamble of claim 1.
Stamping and embossing machines are in a wide variety of designs known for a long time.
the main tool of these machines is a stamp that is usually against the a workpiece lying on or resting against a die brought to a stop or struck under high pressure becomes.
imprinting in the first case one speaks of imprinting, in the second Case of a die cut.
the embossing becomes plastic Deformation of the material in question is achieved in the workpiece.
There are also mixed forms in between, for example temple-like areas from an originally closed Workpiece surface are to be formed. there the area in question is partially identified by the stamp punched out of the workpiece, but still remains over bridges connected to the workpiece.
Such workpieces are primarily used with such machines Metals processed, which requires that the stamp forces to be applied must be very large in order to achieve plastic To achieve deformation or separation of the material.
the object of the present invention was a To find punching and embossing machines that are reliable, fast punching or embossing, especially of hollow cylindrical ones Workpieces allowed.
stamp By forcing the movement of the die and the Stamp and the overlays of these two movements with respect to the workpiece to be machined. whose Bracket with only a very small relative movement a reliable and sufficient between stamp and workpiece Punching or Embossing effect on the workpiece achieved.
stamp also allows the stamp to be viewed from the inside of hollow cylindrical workpieces with relatively small Allow inner radii to act outwards.
the Stamp can nevertheless be dimensioned sufficiently large, power transmission without risk of breakage or deformation enable even at high processing speeds.
control disc with the eccentric shaft relative twist angle adjustable coupled to the movements with respect to the workpiece holder, respectively.
workpiece to adapt to the requirements.
shape of the Control disc is also according to needs be adjusted.
a machine according to the invention can thus for example a set of different control disks have, which depending on need or Application for use reach.
the precision and adjustability be further increased and in synchronization with the control of a preferably also via a servo motor rotatable workpiece holder at high Machining speeds with high precision embossing or punching along hollow cylindrical workpieces their scope.
FIG 1 is a schematic longitudinal section through an inventive Punching and embossing machine shown.
the Workpiece 1 to be machined is over a workpiece holder 15, which is connected to the machine frame 16, in the position shown rotatable about the workpiece axis A. held.
a drive shaft 3 for example as Cardan shaft executed, the eccentric shaft 4 is driven.
the angle of rotation of the control disk 5 in relation to the eccentric shaft 4 is preferably adjustable, either continuously or in discrete levels. This adjustment is in usually made when setting up the machine, A controlled, motorized adjustment would also be conceivable, which during operation or during business interruptions could be activated.
the eccentric shaft 4 is coaxial with the control disk 5 arranged, but an eccentric, separate arrangement.
the control disk 5 has a control track on its underside in the form of a circumferential groove 6.
the groove 6 can for example as eccentric to the axis of rotation of the eccentric shaft trained circular or ellipse groove or have any closed shape. In these Groove 6 engages a pin 7, which with the feed carriage 2 is connected.
the feed of the feed carriage 2 can be done via a threaded spindle 18 from a mechanical or electrical Drive drive 19, which is fixed to the machine frame 16 is connected to be set radially to workpiece 1. It is used to set up the machine to the desired one respectively. workpiece diameter to be machined.
the eccentric shaft 4 is mounted in the die frame 8, which radially displaceable with respect to the workpiece axis A. is guided in the machine frame 16.
the die frame 8 is now corresponding the formation of the groove 6 of the control disc 5 periodically in his leadership back and forth, which at the end of the Matrix frame 8 arranged matrix 9 against the edge of the Workpiece 1 comes into abutment. lifted off becomes. This takes place in accordance with the design of the groove 6 Movement with a larger or smaller path, each once per revolution.
a connecting rod is on the eccentric shaft 17 of the eccentric shaft 4 10 arranged, which for example via a connecting pin 11 is connected to the stamp arm 12.
This Stamp arm 12 is also related in the radial direction Slidable on the workpiece axis A in the die frame 8 arranged.
control disc 5 and eccentric pin 17 is a coupled, positively guided movement of both the die 9 and the Stamp 13 causes the relative movement of the stamp 13 with respect to the workpiece axis A depending on the version and Arrangement of the groove 6 of the control disk 5 in relation to Stroke of the eccentric pin 17 can be very small.
the arrangement shown can also be used to stamp 13 from the outside to act on the workpiece 1, and thereby the die 9 to the inside of the workpiece 1 in stop bring, as shown in Figure 2.
the structure is the same as in Figure 1, only the matrix frame 8 and the stamp arm 12 are correspondingly different designed.
FIGs 3 a) to 3 c) are now schematic Supervision of the work area of the previously described, Machine according to the invention shown.
3 a) shows the starting position also shown in Figure 1 the machine in which both the die 9 and the Stamp 13 the greatest distance to the surface of the to be processed Have workpiece 1.
the workpiece holder respectively. the workpiece 1 is stationary with respect to the Machine frame 16 arranged, the die frame 8 is located in its rearmost position, i.e. in the illustration on the left, and the stamp arm 12 in its foremost position, i.e. against the right side.
the groove 6 is shifted towards the right towards the workpiece 1, as shown in Figure 3 b).
the groove 6 of the control disc 5 is designed such that the displacement is such What is great is that the die 9 just stops with the outer wall of the workpiece 1 comes.
this position is already after a twisting movement of 90 ° - 110 ° from the starting position and then reached maintained. This is achieved in that subsequent angular range, the groove 6 with respect to the axis the drive shaft 3 has a constant radius, is designed concentrically circular.
the controller precisely control this servo axis as well as the Rotation of the workpiece holder 15. This allows very high Accuracy and high working speed hollow cylindrical Workpieces punched or embossed from the inside become.
the shape of the groove 6 of the control disc 5 is dependent the stroke of the eccentric pin 17, the type of machining, the Size of the stamp head 14 and the cross-sectional shape and Design of the workpiece 1 determined. It usually does have an egg-shaped, symmetrical shape.
