Definitions

  • the object of the present invention is a multistation carousel for changing the tool of a press.
  • One of the main needs felt in the sector is to be able to handle tools as quickly as possible, in order to reduce the set-up time of the press.
  • the object of the present invention is to resolve the problems of the prior art while taking into account the requirements of the sector.
  • a multistation carousel which allows the tool of a press to be changed quickly and automatically.
  • the carousel is equipped with different types of stations, namely a station for loading/unloading the tool from the press, at least one die changing station and at least one pressing simulation or standby station, so as to allow the simultaneous execution of several different operations on different tools, all loaded onto the carousel itself.
  • the carousel 1 is therefore a circular conveyor suitable for changing the dies of a press or for changing the tool of a press.
  • Such figure 1 shows an example embodiment of the multistation carousel 1 with four stations 2, three of which accommodate a tool A.
  • the carousel 1 is equipped with a load-bearing structure comprising an upper frame 11 supported by pillars 12.
  • a turntable 3 supported by a lower frame 13 that rests directly on the ground.
  • the turntable 3 is rotated by rotation means 31, which are housed underneath it on the lower frame 13.
  • the rotation means 31 comprise at least one slewing ring and a toothed pinion-crown assembly driven by a gear motor which controls the rotation.
  • stopping means located below the turntable 3 are provided to stop the rotation of the same at the stations 2.
  • the turntable 3 is divided into a plurality of equal segments 31, each of which corresponds to one station 2.
  • movable walls for example sliding walls, adapted to separate the turntable 3 into segments 31 to define the operating area of each station 2.
  • the frame also comprises a central column 15, which extends from the upper frame 11 to the turntable 3, which is hollow internally and adapted to house mechanical components and/or electrical cables for handling the moving parts of the carousel 1.
  • the multistation carousel 1 comprises at least three stations 2, i.e. the turntable 3 is divided into at least three segments 31.
  • the carousel 1 comprises a station 21 for loading/unloading the tool from the press, i.e. one of the segments 32 of the turntable 3 is equipped in such a way as to allow the extraction or insertion of a tool (or of a die) from a press.
  • the station 21 is therefore intended to face the exit of the press whereon the tool change is to be carried out.
  • the loading/unloading station 21 comprises, adjacent to the turntable 2, an outer frame 22 whereon the tool is guided.
  • the station 21 also comprises a suspension frame 29, equipped with guides and a hydraulic cylinder, suitable for the translation of the tool A.
  • the station 21 then pushes/extracts the tool from the press onto the floor-mounted outer frame 22 and from there onto the turntable 2 via the suspension frame 29.
  • the turntable 1 comprises at least one die changing station 23, i.e. one of the segments 32 of the turntable 3 is equipped in such a way as to allow the removal of the die extracted from the press from the carousel 1 (and in particular from the tool A), the placement on the carousel 1 of a new die in the tool A to be inserted in the press, and the reheating of the die.
  • the die changing station 23 is therefore equipped with a mechanical arm 24 to allow the replacement of the die.
  • the carousel 1 comprises at least one work station 25 or standby station 27, i.e. one of the segments 32 of the turntable 3 is equipped in such a way as to allow further activities on the tool A extracted from the press or on the new tool to be inserted into the press.
  • the standby station 27 does not require any special equipment, as it is only used as a depot for a tool A awaiting a successive step.
  • the work station 25 is, on the other hand, equipped with additional equipment to enable special activities to be carried out on the tool A, such as maintenance, lubrication and pressing simulation.
  • the work station 25 is equipped with at least one handling device 26, adapted to allow the radial handling of the tool inside the station 25.
  • the handling device 26 is fixed to the upper frame 11.
  • the handling device 26 is a pusher driven by hydraulic cylinders.
  • the handling device 26 also allows the vertical handling of the tool A.
  • the device 26 is equipped with a vertical ram, driven by a hydraulic cylinder and equipped with automatic locks, to lift the upper die half (or tool half) and allow the operator to simulate a pressing step, complete also with lubrication points.
  • the work station 25 comprises, adjacent to the turntable 2, an outer frame 28 whereon the tool A is placed, to allow the operator to perform the required activities on the tool.
  • the multistation carousel 1 is equipped with control and safety systems for the correct and safe operation of the different steps and operations.
  • the multistation carousel 1 comprises three stations:
  • the standby station 27 and/or the changing station 23 is also further equipped as a pressing simulation station 25, i.e. it comprises a handling device 26 (radial and preferably also vertical) of the tool A and an external frame 28 for supporting the tool during the required work activities.
  • a pressing simulation station 25 i.e. it comprises a handling device 26 (radial and preferably also vertical) of the tool A and an external frame 28 for supporting the tool during the required work activities.
  • the multistation carousel 1 comprises four stations:
  • the standby station 27 and/or the die changing station 23 is also further equipped as a pressing simulation station 25, i.e. it comprises a die handling device 26 (radial and preferably also vertical) and an external frame 28 for supporting the tool during the required work activities.
  • a pressing simulation station 25 i.e. it comprises a die handling device 26 (radial and preferably also vertical) and an external frame 28 for supporting the tool during the required work activities.
  • only the changing station 23 is also further equipped as pressing simulation station 25.
  • a multistation carousel 1 in accordance with the present invention allows the tool and die of a press to be changed quickly and automatically.
  • a multistation carousel 1 in accordance with the present invention being provided with different types of stations (loading/unloading of the tool from the press, die changing, pressing simulation, standby) allows the simultaneous execution of several different operations on different tools, all loaded on the carousel itself.
