Definitions
- the present invention relates to a punching device for a follow-cut punching machine for the production of metal stamped parts according to the preamble of patent claim 1.
- the metal part is processed in a series of workstations which are each provided with at least one punch and one die, each of which is provided for carrying out a specific work step, for example for severing and / or folding and / or drawing or thermoforming.
- a specific work step for example for severing and / or folding and / or drawing or thermoforming.
- the metal part changes shape until the final shape is achieved according to the design drawing.
- stamp here always a combination of one or more stamps in conjunction with its own associated die to understand.
- a "simple" punch press that can perform a single punching operation has a punch and a single die, while a progressive punch press has a series of punches, each with its own die.
- the feed of the sheet metal strip, and thus also of the stamped part is given by the feed device of the punch press, which advances the strip by one "step" for each punching stroke (the step being in the case of a number of more than two workstations of the follow-cut punch press is equal to the distance between one workstation and the next one).
- the above-described technology of the following step punching can not be used, in which the stamped part remains connected to the sheet metal strip and thus transported with it until it is cut off (cut off) only at the last work station. It may happen, for example, that certain stampings have no area in which the connection with the sheet-metal strip can remain. In such cases, the stamped part must already be separated from the band at the first workstation and then brought as a separate or independent part to the subsequent workstations.
- transfer punching technology in which the punching device is replaced by a series of individual stations arranged in a straight line, the transfer from one station to the next by means of a series of grippers accomplished, which are attached to a transporting arm.
- transfer punch press Such a transport system becomes an integral part of the stamping press, thus called “transfer punch press”, which is a special punch press type.
- this particular type of punch press is known as a "transfer punch press", with punching stations arranged in a single plane for punched parts cut off from the sheet metal strip from the first work station.
- This is, in the sense of an example, from the EP0778094 can be seen in the gripper devices formed by gripper tongs, with an access station and with an unloading station, wherein each of the clamping devices is mounted on a suitable sliding rod, or from the DE4022560 in which the punching stations are arranged along a zig-zag course to reduce the space requirement, the gripper arms transporting the stamped parts along this path.
- the Fig. 1 shows the punching press according to the invention in elevation. It consists of an upper part 1 and a lower part. 2
- Fig. 1 In the Fig. 1 are the two parts 1 and 2, which together form the punching device, are shown lifted off from each other: this is the position of the punching device in its open position or rest position. It is clear that in the working position, the punching stroke, the upper part 1 lowers to the lower part 2, so that the stamp (in the Fig. 2 only one punch 3 is shown in section) can penetrate into the corresponding dies 4, which in the Fig. 2 can be seen better, showing the bottom of the punching press in plan.
- the punching device 1,2 is shown on a punch press, which is not shown here for the sake of clarity, and because it is a conventional punch press type comprising a base 2 supporting frame, a horizontal portal on which the upper part. 1 the punching device is attached, as well as vertical guides along which the portal can move upwards (for opening the punching device) and downwards (for closing the punching device during the punching stroke), and the required movement and control mechanisms for the portal. All these movements are in the Fig. 1 indicated by the double arrow f itself, which indicates the movements of the upper part of the punching device upwards and downwards.
- the upper part 1 of the punching device consists of a substantially horizontal plate 5, on which the punch 3 in a well-defined arrangement resulting from the positions of the dies 4, which are fixed in the lower part 2 of the punching device, and, as explained later is a basic aspect of the present invention, as well as four guide elements 6 (one for each corner of the plate 5) whose purpose it is to guide the plate exactly when lowering on the lower part 2 of the punching device.
- Fig. 2 showing the bottom part 2 of the punching device with the top removed in plan view.
- Fig. 2 corresponds to the horizontal plate 8 of the lower part 2 of the punching device in shape of the plate 5 in the upper part 1, wherein through the center of the axis of rotation 9 of an arm star 10 extends, which is provided with gripper claws 11.
- the processing stations 12, 13, 13 ', 13 ", 13"' have matrices 4, each of which is designed for the operation to be performed in cooperation with the corresponding punch 3.
- Each processing station is thus equipped with a punch and a die which are different from those of the preceding station, so that the continuous deformation of the stamped part is performed.
- the processing stations 12, 13, 13 ', 13 ", 13"' and 14 are arranged according to the invention along a circular path which begins with a loading and cutting station 12 and ends with an unloading station 14.
- the charging station 12 while the stamped part is separated or cut from the metal strip 15 and thus becomes an independent part, which at best also experiences a first deformation by pulling during the separation, and thus, after it has been gripped by the gripper jaw 11 of the corresponding arm of the arm star 10, can be transported to the next processing station 13 , To perform this operation, the arm star 10, starting from his in the Fig.
- the arm star 10 shown at first a rotational movement about the center of the circular path from, in the counterclockwise direction, over an angle corresponding to half the angular distance between two successive arms of the arm star 10, so that the gripper claw 11 over the separated in the processing station 12 part located. Then, the claw 11 suitably grips the part and the arm of the star-shaped arm 10 rotates clockwise through an angle corresponding to the angular distance between two consecutive arms of the arm star 10, so that the part is in coaxial coincidence with the processing station 13 is brought. Then, the arm star 10 returns to its original position by making a counterclockwise rotation through an angle equal to half the angular distance between two successive arms of the arm star 10.
- the number of arms of Arm Star 10 depends on the number of processing stations provided along the circular path, and is always equal to this number minus one.
- FIGS. 1 and 2 In the illustrated case of an implementation of the present invention, which may be considered as a preferred case for many practical applications, six processing stations 12, 13, 13 ', 13 ", 13"' and 14 are provided which are angularly spaced from one another by 60 ° station arranged to the other.
- the arm star 10 has five arms, between two of which - those cooperating with the loading and unloading station 12 and the unloading station 14 - the angular distance is 120 °.
- FIGS. 1 and 2 is, merely in the sense of an example, a drive motor 17 for the arm star 10 shown, which acts via a reduction gear 18 and a camshaft 19.
- this arrangement is not part of the inventive idea and is left to the creativity of the designer.
- the present invention has been described here on the basis of a vertical punch press, in which the upper part 1 of the punching device is lowered onto the lower part 2 in a vertical movement.
- This is a preferred way of realizing the inventive concept, as it allows the use of normal punching presses with vertical lifting movement.
- the present invention can also be applied independently of the particular arrangement of the plane in which the circular path of the processing stations is designed, for example on stamping presses in which the lifting movement of the punching in the horizontal or similar (inclined) direction he follows.
- the access type of gripper jaws 11, 11 ', 11 ", 11"', 11 IV of the arm star 10 on the stamped part depending on the shape of the can be different to be produced stamped part.
- the gripper jaws 11,... 11 IV are equipped with pliers which mechanically grasp the stamped part, wherein according to a further preferred embodiment of the present invention, the pliers are pneumatic or hydraulically operated.
- a further preferred embodiment of the present invention then provides that the gripper jaws 11, 11 ', 11 ", 11"', 11 IV are equipped for the metallic stampings with suction cups, which access by means of pneumatic suction, or by means of magnetic attraction.
