Definitions

  • the invention relates to a transport device of workpieces by processing stages of a transfer press according to the preamble of claim 1.
  • the production of a workpiece requires several machining processes, such as cutting and forming, the necessary individual operations are carried out in a so-called step press for economic production.
  • the number of tools then corresponds to the number of work stages that are required for the production process of the workpieces.
  • the transport device In the presses are transport devices with which the workpieces are transported from one workstation to the next.
  • the transport device can be designed as a 2-axis transfer or 3-axis transfer, whereby the axes of movement of the means of transport are defined.
  • a 2-axis transfer running on both sides through the press support rails are provided on those equipped with suction cups or the like crossbeams for workpiece transport are fixed, which perform an overlapping horizontal and vertical movement.
  • the support rails are designed as so-called gripper rails, which in addition to the horizontal and vertical movement still perform a transverse movement and grip by means of gripper elements the workpiece to transport this from one processing stage to the next.
  • the 3-axis or gripper transfer is preferably used for transporting externally grippable, rigid sheet metal parts.
  • the drive of the three axes can be done directly via cams and levers of the press drive or each movement axis is equipped with a self-propelled.
  • a 3-axis transfer with its own drives is in the U.S. Patent 4,887,446 disclosed.
  • an electric linear drive is proposed for the execution of the horizontal movement of the support rails.
  • a device for coupling and decoupling gripper rail parts is in the generic DE 36 36 010 described in detail.
  • As a connecting element or gripper rail lock acting according to the swing tensioner principle device is proposed.
  • In addition to the required complex design requires in particular the achievement of a free space of the gripper rail parts to each other, the change process, a considerable effort.
  • this movement can also be done by dolly on the mounting rails.
  • the invention is based on the object for a press and in particular for a transfer press with two- or three-axis transfer form a linear drive for the horizontal movement such that it is designed inexpensively and results in a compact design even with high power requirement.
  • the linear drive should allow easy replacement of the gripper rails when a tool change.
  • the invention is based on the idea to provide two linear drives per support rail for the horizontal movement. These linear drives are arranged so that in a simple way, the change of the support rail is possible.
  • the linear motors are located substantially at the outer ends of the mounting rail. These outer ends are separated from the support rail to be replaced and detachably connected thereto via mounting rail locks.
  • the DIN rail locks are also located in the independent end pieces and only one clamping head engages in the interchangeable mounting rail.
  • the connection is released and driven by the linear motors, the end pieces horizontally apart by a defined amount, creating a trouble-free tool change is possible.
  • the mounting rail lock can be formed in a very simple form by this movement.
  • the support rail is formed in a preferably used 3-axis transfer as a gripper rail.
  • the linear drives drive the DIN rail end pieces with the DIN rail locks located therein so far in the direction of the mounting rail, that the clamping heads can engage in the provided in the mounting rail receptacle.
  • the DIN rail locks tighten the DIN rail and the Together end pieces and thereby the support rail is also firmly connected to the linear drive.
  • linear drives advantageously fulfills the stated object.
  • Recent developments provide drives with high dynamics and fast stroke sequence. Since these drives work wear-free, a lasting high positioning accuracy over the entire life cycle is guaranteed.
  • the reliability is increased with the use of two drives because in the failure of a drive of the second drive the support rail and in particular the gripper moves on a gripper rail from the collision area.
  • the exemplary embodiment describes a 3-axis transfer with gripper rail drive.
  • FIG. 1 is shown by a step press 1 of the plunger 2 and sliding table 3 to which the upper tools 4 and lower tools 5 are attached.
  • the so-called lock boxes 8, 9 are arranged in the area of the stand 6, 7, the so-called lock boxes 8, 9 are arranged.
  • These lock boxes 8, 9 are provided with drive devices which perform a vertical and a closing stroke of the mounting rails or gripper rail 10.
  • Such lock boxes 8, 9 are known and eg in the DE 43 36 854 A1 described in detail by the applicant.
  • the connections of the gripper rail 10 with the end pieces 11, 12 cause gripper rail locks 13.
  • the gripper rail locks 13 are designed as swing clamps or rotary tensioning whose basic body 14 with the clamping drive directly in the hollow section of Gripper rail end pieces 11, 12 are integrated, while the clamping heads 15 engage in the corresponding receptacles of the gripper rail 10 and tension.
  • the linear drives are denoted by 16 and 17 and consist of a primary part 18, 19 and a secondary part 20, 21.
  • the primary part 18, 19 is arranged on the lock boxes 8, 9.
  • the secondary part 20 is connected to the gripper rail end piece 11 while the secondary part 21 is divided and is attached to both the gripper rail 10 and the gripper rail end piece 12.
  • the linear drives 16, 17 effect in the 3-axis transfer, the horizontal movement of the workpieces in the transport direction 22 and the return stroke against the transport direction 22nd
  • the situation for a tool change shows FIG. 2 ,
  • the gripper rail locks 13 are open and by the linear actuators 16, 17, the gripper rail end pieces 11, 12 horizontally and oppositely moved far enough apart that a clearance is given to the gripper rail 10.
  • the uncoupled gripper rail 10 is on recordings 23, which are located on the sliding table 3, stored and held.
  • the division of the secondary part 21 in a part which is fixed to the gripper rail 10 and a part which is located on the gripper rail end piece 12 allows for the shortest design and low horizontal movement the required space for gripper rail change.
  • FIG. 3 In the sectional view, in the region of the gripper rail part, the arrangement of the linear drive 16 can be seen.
  • the primary part 18 is connected to a receptacle 23 of the lock case 8.
  • the gripper rail end piece 11 is guided and held in the receptacle 23.
  • the device according to the invention can in principle also be transferred to a 2-axis transfer with suction bar workpiece transport.
