Definitions
- the invention relates to a transfer device for Multi-stage presses, especially for massive forming.
- the invention relates to a transfer device for stepped presses where forming tools in are arranged in a row.
- Step presses are mostly used for extrusion, where from a solid blank through several successive forming steps a desired workpiece arises. There are separate ones for each forming step Tools required. The workpiece must therefore between individual forming steps from tool to tool to be transported further. For multi-stage presses are the workpieces on a common table in one Row arranged. Associated top tools are also attached in a row to a pestle. The The transfer device now has the task of handling the workpieces then transported in cycles from tool to tool, when the ram releases the tools.
- massive forming is particularly suitable for mass production is suitable for large and recurring same workpiece lots must be machined massive forming increasingly for smaller workpiece lots Application.
- After the forming tools each especially for the production of a single type of workpiece serve up when setting up the multi-stage press a specific workpiece or when retooling Tool change required.
- the tool change should not be done by im In the area of the tools, standing gripper means is obstructed be on the transfer device for workpiece transport are provided.
- the one used for the further transport of the workpieces Transfer device usually has grippers that are adapted to a special workpiece type. In this In addition to changing the workpiece, this also includes changing the gripper required when converting the multi-stage press shall be.
- DE 34 43 874 A1 describes a transfer device for moving workpieces in one Multi-stage press known. This transfer device points a set of arms held parallel to each other Pliers on. The arms are each approximately at right angles arranged in a line through the series in succession Workpieces is defined.
- the pliers moving on approximately semicircular paths become.
- the Pliers opened and closed, each for separate Serve drive devices. These point to the arms intended and leading through this gear means, which are driven by cams.
- the pliers are purely passive with Provide spring clamps.
- Individual pliers are provided for workpiece transfer, their drive and / or adjustment is relatively complex can be.
- EP 00 41 690 B1 is a multi-stage forming machine known for massive forming.
- the forming machine has several in a row on a support arranged tool stages, which is a solid blank has to go through.
- a pliers apparatus also serves for the tool level two pliers boxes that are translationally synchronous to each other are movable.
- a transfer facility for creating multi-stage presses that are simple is convertible.
- the transfer facility be simple, work precisely and can be converted easily.
- the carrier means designed as gripper rails are arranged on one side of the tool row and therefore give the other side of the tools (front) free.
- access to the tools is significantly easier. This is not exacerbated by the disadvantage of more complicated gripping devices bought like it when using gripping tongs or the like would be the case.
- the gripping devices of Grippers formed, each containing two gripper fingers.
- the first gripper fingers are with the first Gripper rail connected and the second gripper fingers are connected to the second gripper rail.
- a translatory opposite adjustment of the gripper rails permitted in their respective longitudinal directions thus opening and closing all grippers.
- the opposite Allows movement in relation to the workpiece that the clamped workpiece is in the same position is held like that freely in the respective tool seated workpiece. In this way, a tilting Tilting or incorrect insertion of workpieces certainly excluded.
- the gripper fingers in are resilient in a certain area, it is advantageous if they are essentially rigidly trained Booms that extend from the respective gripper rail stretch away.
- the gripper fingers are structurally simple designed and the adjustment effort is limited to a minimum.
- a solution that makes it particularly easy to change the gripper allows is obtained when the gripper fingers are connected to an attachment rail, which can be detached the gripper rail is held.
- To replace the The gripper is simply changing the top rails required, in the simplest case per top rail only two screw connections have to be loosened.
- the gripper fingers intended for each workpiece type remain firmly attached to the top rail and pre-adjusted in relation to this.
- the gripper rails are preferably one common carrier device worn with respect to the multi-station press is movably mounted and over appropriate Drive devices is specifically adjustable.
- the carrier device can be raised and lowered and in Adjustable lengthwise.
- the gripper rails are over Carriage or linear guides on the carrier device held and longitudinally adjustable in relation to this. Thereby can open and close the gripper fingers be obtained regardless of the transport movement that is granted to the carrier as a whole.
- the Carrier device with both gripper rails and gripper fingers from the neighborhood of the Tools can be swiveled into a rest position which is further away from the tools.
- the rest position is free access to the tools grants what a particularly easy tool change enables.
- the Carrier device and the gripper rails When swiveling into the rest position, the Carrier device and the gripper rails preferably around pivoted an axis of rotation parallel to the longitudinal extent the gripper rails is arranged.
- Transfer device has a common drive means for the opposite longitudinal adjustment of the gripper rails for opening and closing the grippers and for the transfer movement on that of the carrier device and thus both gripper rails is issued synchronously.
- the drive device is, for example, a central shaft Cam discs over a gear with a worm drive communicates.
- the axis of rotation of the worm wheel is also the axis of rotation about which the carrier device when swiveling in and out of her Rest position is pivoted. That way they can Carrier device and the drive devices assigned to it pivoted about an otherwise stationary drive become.
- the solution is mechanically simple and robust.
- the translational movement to open and close the gripper rails can be easily obtained by the gripper rails each of two crank cores to be worn on the carrier device are stored.
- the advantage and the peculiarity of this The solution is that when the gripper fingers are transferred a circular arc in the respective gripping position Infeed movement to the individual workpieces carried out becomes. As a result, the lateral infeed movement disappears the gripper finger just before the gripper finger come almost completely into contact with the workpiece. It is therefore the gripper fingers despite the side infeed a pure clamping movement in relation to the workpieces reached and a lateral shifting and tilting of the Workpieces are avoided.
- the gripper rails are preferably driven via a rack that runs parallel to the gripper rails mounted on the carrier device and by a gear pinion is driven. This in turn is over driven by a cardan shaft, its movement from a Cam derives.
- the cardan shaft enables that translational movement of the carrier device under Carrying the gear pinion without twisting it. In this way, the transfer movement is decoupled (Lifting, lowering, feed, i.e. synchronous Movement of both gripper rails) from the gripping movement (opposite movement of the gripper rails) reached.
- FIG. 1 is perspective and highly schematic a multi-stage press 1 shown as the massive forming of workpieces across five tool levels serves.
- the multi-stage press 1 has a table 2, on which a tool base frame 3 is mounted in a stationary manner.

- the resulting movement of the gripper rail 13 and Gripper fingers 15 (a to f) are illustrated by arrows 29.
- the crank link 23, 27 and the crank link 24, 28 are in pairs only schematically indicated gears 31, 32; 33, 34 with each other in Intervention.
- the gears are so big and arranged so that the crank links 23, 27; 24, 28 each turn in pairs in opposite directions at the same speed, if they are driven.
- gear pinion 39 rotatable on the carrier 19 mounted, which is in engagement with the rack 36.
- the gear pinion 39 is also connected via a cardan shaft 41 connected to a drive source 42, the cardan shaft 41 a translational movement of the gear pinion 39 in Direction of arrow 21 allows without rotating the To cause gear pinion 39.
- a drive source 42 for the gear pinion 39 and thus for opening and closing the pairs of gripper fingers serves a control shaft 43, which via a gear 44 a screw 45 (Fig. 3) is driven.
- the continuously rotating worm 45 drives the control shaft 43 synchronized with the working strokes of the plunger 8.
- From the Continuous movement of the control shaft 43 is based a cam plate 47 via a not shown Lever and gear tap a periodic targeted Movement of the gear pinion 39 brought about.
- Additional cams 49, 50 do not effect one further illustrated lever drive the transport or Feed movement of the carrier 19 in the direction of the arrow 21.
- the lifting and lowering of the carrier 19, however, is by a cam 51 derived on the control shaft 43 sits and the corresponding lever gear Raising and lowering the carrier 19 causes.
- the transfer device 11 forms including the Control shaft 42 is a structural unit which, as in FIG. 3 is indicated from the working position to a rest position is pivotable.
- the gripper fingers 14, 15 put the rest position in dashed lines indicated path 53 back. Your resting position is indicated at 54.
- the pivot axis is the axis of rotation the worm 45, with the gear 44 around the Snail 45 is pivoted.
- the multi-stage press 1 described so far works as follows:
- the gripper fingers 14, 15 (a to f) are almost closed and withdrawn position.
- the crank link 23, 27; 24, 28 by about 180 ° against the respective position shown in Fig. 2 rotated.
- the Gripper rails 12, 13 are in their Matrices 5 (a to e) as far away as possible.
- the cam disks 49, 50 act Shifting the carrier 19 towards the transfer station 17 to, i.e. 2 to the left. Is this position reached and the plunger 8 moved so far up that the matrices 5 (a to e) are free, reaches the cam 47 in their rotation an area where they begins the gear pinion 39 via the cardan shaft 41 to rotate the rack 36 to the left in Fig. 2 is moved.
- the crank handlebar runs 23 from its position marked by a cross 56 in the position shown. The turns accordingly Crank handlebar 24.
- crank links 23, 24 counterclockwise run
- the crank links 27, 28 rotate in Fig. 2 clockwise also from their matrices 5 (a to e) pointing in the position shown, position to be pointed at.
- the gripper fingers 14, 15 each like a pair of pliers Circular arc, which is indicated by the arrows 25, 29. It is thereby the in the transfer station 17 and the the following tool stations and thus clamped by the gripping fingers 14, 15.
- a slope-free area of the Cam disc 47 reached so that the gear pinion 39th stop shooting.
- the cam disc 51 now controls a lifting movement, whereby the carrier 19 with the gripper rails 12, 13, Grippers 14, 15 and the workpieces located therein is lifted. Shortly afterwards or overlapping in time begins that caused by the cam disks 49, 50 Transfer movement in Fig. 2 to the right, i.e. on the Failure station 18 too.
- the stroke corresponds to the transfer movement exactly the same distance from each other spaced matrices 5 (a to e).
