Furthermore, the describes DE 34 08 413 C2 a device for removing a workpiece adhering to a punching tool after the raising of the tool carrier following the punching operation with an actuating tip attached to a lever whose movement is controlled by levers of a four-bar linkage in cooperation with the moving tool carrier so that when starting the tool carrier the Operating tip under the Tool carrier moves and when shutting down the tool carrier from the area under the tool carrier moves out again.
Another known solution (see DE 87 14 829 U1 ) provides a device for removing parts from a punch, a press o. The like. Before, the one movable in the movable or upper tool, the tool during the return stroke of the upper or movable tool from this tool demoulding ejector, a, transversely movable to the working path, by means of a coupled with the movement of the movable tool actuating device optionally in the working path of the movable tool in and out of this movable and laterally engageable with the workpiece ejector element.
In the DE 82 02 852 U1 In addition, there is disclosed a work ejection apparatus for a press comprising a frame with a first tool and a carriage liftable in the frame relative to the first tool between first and second carriage positions. The ejector has an ejector which is hydraulically operated.
The DE 1 752 242 A1 suggests pneumatic actuation rather than hydraulic actuation of the ejector. Furthermore, from the EP 0 148 354 A1 a device for removing parts from a punch, a press or the like, in which the workpiece during the upward return stroke of the upper tool is preferably removed from the mold by means of an ejector down from the tool. It is a transversely extending to the working path, leaving the tool workpiece on the underside supporting deflection provided by means of an actuator selectively in the Working path of the upper tool is movable. The blast unit used with this known solution causes when hitting a fine atomization of the oil located on the parts, the corresponding filter devices for cleaning the exhaust air required to avoid hazardous indoor air pollution and pollution of machinery and workpieces, which adds the expense elevated.

All these known solutions have the disadvantage in common that they lead to damage to the surface of the parts, on the one hand by the sudden action of the high-speed ejector elements on the parts surface, on the other hand by the possible damage to the surfaces due to the clash of the parts with each other when leaving the working space between upper and lower tools.
Precision parts, as they are regularly fineblanking parts, not only have to meet high standards of compliance with tolerances, but also have a high surface quality, therefore, the known solutions lead to a very high proportion of rework on the finished parts.
Moreover, it is not possible with these known solutions to remove workpieces and Abfallbutzen separately from the tool, whereby the cost increases and the efficiency is impaired.
Another disadvantage is that the heights of the known solutions for the well-known in fine cutting available lower opening height of the tool are much too big, if not even unsuitable.
In addition, the known solutions do not reach the high delivery rates required for high speed presses.

example 1

In the example described below, with the device according to the invention a fine blank is processed without waste slugs.

The Fig. 1 schematically shows the basic structure of the device according to the invention, which also applies to Example 2. A fixed to the press frame 1 of the press 14 liquid-cooled torque motor drives as a direct drive 2 via its shaft 3, a lever 4 at.
The direct drive 2 achieves accelerations of up to 100 m / s ² and speeds of up to 3.5 m / s at max. 250 mm stroke.

The lever 4 is one end fixed against rotation of the shaft 3 and the other end hingedly connected to a tab 5 in the pivot point A, which in turn via a quick coupling 6 and overload protection 7 (see Fig. 2 ) is hinged to a cross slide 8 in the pivot point B. Below the cross slide 8 is a transport means 9, for example, a slide for discharging parts is provided. The chute consists of juxtaposed with side walls 11 provided discharge channels 10, the width of which are matched to the dimensions of the parts.

The controller 12 of the torque motor is controlled by the controller 13 of the press 14, in such a way that, depending on the plunger position, the direction of rotation of the shaft 3 is reversed, so that the lever 4 performs a pivoting movement in an alternating direction, ie the hinge point A. moves on a circular arc whose respective reversing position is matched to the ram position. The hinged at the hinge point B cross slide 8 performs a linear movement between its front end position D and its rear end position C (see Fig. 4 ) Based on the spanned between the lower and upper tool part 15 and 22 working space E with open tool.

The lower tool part 15 is located on a tool plate 16, which in turn is mounted on a tool change plate 17. The tool change plate 17 is hydraulically clamped on the press table of the press 14. For the lower tool part 15 includes at least one cutting plate 19 and an ejector 20, wherein the fine blanking part 21 in the cutting plate 19 by a tool in the upper part 22 in a guide plate 23rd guided cutting punch 24 is cut with the tool closed (see Fig. 6 ). The ejector 20 serves to eject the fine blanking part 21 from the cutting plate 19. The upper tool part 22 is guided on columns 25 of the tool plate 16 screwed onto the tool change plate 17.

The cross slide 8 is -as out of the Fig. 2 and 3 is removable from a part plate 26 and a base plate 27 together. The base plate 27 has on its longitudinal sides rails 28, which 27 stops 29 are assigned to the end faces of the base plate. The sub-plate 26 has on each of its longitudinal sides on the rails 28 facing sides at least two running elements 30 which guide the parts plate 26 along the rails 28 linearly as soon as the lever 4 performs the pivoting movement and this movement on the tab 5 and the quick coupling 6 in a linear movement of the part plate 26 is converted. The rails 28 and the running elements 30 form the linear guides for the part plate 26 on the base plate 27th
In the rear end position C is the part plate 26 outside of the tool in the normal position and the tool is closed, in the front end position D, the part plate 26 is fully retracted with the tool open in the working space E and takes the working position (see Figure 4 ).
The side of the parts plate 26 facing the lower tool part 15 is provided with a mask 31, which is formed from openings / recesses 32 adapted to the contour and geometry of the fine stamped parts 21. The detail X in Fig. 3 shows variants of the embodiment of the mask 31, the For example, from an opening 32 with cover or a recess 32 may be formed on the underside of the part plate 26.

In the parts plate 26 a plurality of openings 33 and recesses 34 are incorporated, which help to reduce the mass of the plate in order to achieve corresponding acceleration values and high speeds in the movement of the parts plate 26. The base plate 27 also has on its side facing the lever 4 end a recess 35 for the lever 4 and tab 5, so that they can penetrate the base plate 27 without contact in their movement. Furthermore, the base plate 27 has a recess 56 for the passage of the fine cutting parts 27 and further recesses 35 for reducing the mass of the base plate 27th
The quick coupling 6 with overload protection 7 is mounted in the rear region of the rear end side at the top of the part plate 26.

The base plate 27 is fixed by means of spacer elements 36 on the tool plate 16. The spacer elements 36 extend along the longitudinal sides of the base plate 27 from the end face facing C to the rear end position on a length which ensure a secure support and support of the base plate 27 on the tool plate 16. They have such a height that the part plate 26 is located approximately at the level of the cutting plate 19 and the ejected fine blanking or fine cutting 21 can be pressed into the openings 32 of the parts plate 26 through the ejector 20 in the lower mold part 15.

The part plate 26 is designed tool and workpiece specific, ie the contour and geometry of the openings 32 in the part plate 26 are adapted to the respective tool geometry of the tool and cutting geometry of the parts (see also Fig. 3 ).

The quick coupling 6 with overload protection 7 makes it possible on the one hand quickly decouple the direct drive 2 from the cross slide 8 for replacing the part plate 26 and on the other hand, when blocking the part plate 26, the tab 5 abruptly separated from the part plate 26. The quick coupling 6 ensures short changeover times of the press 14 on parts plates 26 of different geometry.

The high-speed discharge of fine cutting parts 21 from the working space E defined between the upper and lower tool parts 15 and 22 proceeds as follows.
At the bottom dead center of the plunger of the press 14, the opening of the tool between the lower tool part 15 and the upper tool part 22 reaches its maximum value, for example 250 mm.
The driven by the torque motor, located in the basic position lever 4 pivots and moves over the tab 5, the part plate 26 from its rear end position C in its front end position D. The end position D corresponds to the working position, ie the part plate 26 is ready, from the insert Receive 19 ejected by the ejector 20 fine stampings 21 in their openings 32.

After the ejector 20 has pressed the fine blanking member 21 in the opening 32, there is a reversal of the direction of rotation of the torque motor and the lever 4 moves the Hinge point A back, so that the part plate 26 performs a linear movement from the working position (end position D) in the basic position (end position C). The part plate 26 takes in the openings 32 located fine stampings 21 to the chute, on which the fine stampings 21 are then removed.
The tool closes, ie the plunger of the press 14 moves to the top dead center, and from the material strip clamped between the upper and lower tool parts 15 and 22, a new fine blanking member 21 is cut with the cutting punch 24 in the cutting plate 19. The discharge of the fine cutting part 21 from the working space E begins again.

Example 2

With the inventive device according to Example 2 fine blanking or fine blanking parts 21 and waste slug 37 are to be discharged separately from the working space E of the tool. The basic structure of the device according to the invention shown in Example 1 is retained.

The cross slide differs - like Fig. 5 shows- compared to the cross slide 8 in Example 1, characterized in that on parts plate 26, a Butzen plate 39 is arranged stationary, which coincides in length with the length of the parts plate 26. The slug plate 39 is provided on its longitudinal sides in each case with rails 40, between which a Butzenschieber 41 is linearly displaceable relative to the displacement position of the parts plate 26 between the basic position and working position. The slug plate 39 and the rails 40 are secured to the part plate 26 by screw connections.
The slug plate 39 and the part plate 26 have superimposed congruent diarrhea openings 53 and 54, which are associated with the rear end position C for removing the Abfallbutzen 37 (see Fig. 7 and 8th ).

The Butzenschieber 41 is composed of a resting on the Butzen plate 39 plate 42, running elements 43, a brush ring 44 and a rear end position C and front end position D along a longitudinal side of the Butzen plate 39, mounted on the parts plate 26 cable drive 45 together. The plate 42, whose longitudinal and width dimension is significantly smaller than the longitudinal and width dimension of the slug plate 39, has an opening 46 and carries a brush ring 44 which surrounds the opening 46. The flexible brushes 47 of the brush ring 44 are supported by a flange-shaped ring 48 and protrude therefrom perpendicularly from the plate 42. The ring 48 is held on the plate 42 by screw 49. The flexible brushes 47 allow an early start of the drive when moving apart of the lower and upper tool part and close the collecting space largely.

On the longitudinal sides of the plate 42, the running elements 43 are fixed, which slide on the rails 40 during the relative movement of the slipper shifter 41 on the Butzen plate 39. The cable drive 45 includes one of the rear and front end position C and D associated roller 50 for deflecting a circulating between the rollers rope 51. The rope 51 is fixed to a fixed, attached to the base plate 27 cable holding block 52 and the terminal point G clamped. During the forward or backward movement of the parts plate 26, the rope 51 moves around the two rollers 50 and pulls the Butzenschieber 41 over the driver 53 forward or backward.
On the rope 51, a driver 53 is clamped thereto, which is connected to the attachment of one of the running elements 43 on the cable drive 45 facing the longitudinal side of the Platts 42. The nip F of Butzenschiebers 41 on the rope 51 is selected so that the Butzenschieber 41 is in its normal position, ie in the rear end position C.

The separate discharge of fine stampings 21 and waste slug 37 from the defined between the upper and lower mold parts 15 and 22 working space E runs as follows.
The basic position of the modified cross slide 8 described in Example 2 shows Fig. 7 in which, for reasons of clarity, the upper tool part 22 has been omitted. In the basic position, ie the rear end position C, the tool is closed and the cross slide 8 is located outside of the working space E of the tool (see Fig. 6 ).
The Butzenschieber 41 also assumes its basic position. In other words, the diarrhea opening 53 in the slug plate 39, the diarrhea opening 54 in the divider plate 26, the opening 46 in the plate 42 of the slipper valve 41 and the recess 55 of the base plate 27 are superimposed and give the passage for waste slug 37 on the transport means arranged thereunder 9, for example, a slide for Wegfuhr the Abfallbutzen 37 free (see Fig. 8 ).

The Fig. 8 shows the modified cross slide 8 in its working position with the tool open. The part plate 26 has along the linear guides of the base plate 27 by the pivotal movement of the lever 4 in their rear end position C moves. At the same time as this movement, the cable drive 45 has displaced the Butzenschieber 41 on the Butzen plate 39 in its matching with the front end position D working position, whereby the Butzen plate 39, the opening 46 in the plate 42 completely covers. The brush ring 44 thereby forms a collecting space 55 for collecting Abfallbutzen 37th

With reference to the Fig. 6 showing the modified cross slide 8 inserted between the lower tool part 15 and the upper tool part 22, the ejectors 38 are guided inside the cutting punch 24 in the upper tool part 22, which serve to eject the waste slugs 37 as soon as the upper tool part 22 opens or the parts plate 26 and the slipper valve 41 have reached the front end position D.
The ejected Abfallbutzen 37 fall into the collecting space 55 of the brush ring 44th
When this is completed, the cable drive 45 shifts the slipper shifter 41 linearly on the slug plate 39 in the direction of the front end position D. The brush ring 44 passes over the superposed Durchfallsöffnungen 53 and 54 of slug plate 39 and parts plate 26 and the recess 55 of the base plate 27, so that the waste slugs 37 pass through their gravity on the transport means 9 for Wegfuhr the slugs.

The ejector 20 in the lower tool part 9 has the finished stamped part 21 pressed into the opening 32 of the parts plate 26 and the part plate 26 moves due to the reversal of direction of the direct drive 2 in the linear guides of the base plate 27 toward the rear End position C. The part plate 26 takes with it the fine stampings 21 located in the openings 32 up to the transport means 9, which then removes the fine stamped parts 21.
The further procedure corresponds to that of Example 1.

The transport means 9 is in this case a chute, the discharge channels 10 having a width which corresponds approximately to the dimensions of the fine stamped parts 21. The Abfallbutzen 37 fall through the diarrhea opening 54 on the above and behind the slide for the fine stamped parts mounted additional slide.
