Definitions

  • the present invention relates to a unit for handling, separating, assembling and turning of two-part press and punch tools and the like comprising a lower part and an upper part which are fitted together by means of guides.
  • the tool For maintenance, repair work and exchange of tools for presses and the like the tool consisting of an upper part and a lower part is detached in assembled condition from the press or the like.
  • the tool which may have considerable dimensions and heavy weight, must thereupon be spaced apart to give access to its interior. Hitherto the upper part of the tool has usually been lifted up by means of more or less provisional units from the lower part placed on a suitable bed, which would not per se cause any particular trouble in the normal case provided that it has been possible to carry out the lifting operation in parallel with the guide studs of the tool so that no locking would take place between guide columns and guide bushings.
  • the object of the invention is to provide a unit permitting unproblematic disassembling and assembling of tools and also permitting safe and unproblematic turning of the upper part of the tool.
  • the essential characteristic of the unit of the invention is that the unit includes two columns between which there is a space for receiving a roller table or a similar carrying means, a pair of lifting yokes being vertically and synchronously movable along the columns on either side of said space, and a crosspiece arranged between the columns above the space and provided with a fixture designed for connection with the upper tool part, said crosspiece being connected with the columns by means of members which are movable into and out of engagement with the cross piece and permit turning of the crosspiece around a horizontal axus, and that the lifting yokes and the crosspiece are provided with stop and positioning means adapted to permit connection of the lifting yokes with the crosspiece in two turning positions and vertical displacement of the lifting yokes between the columns when the members for turning around the crosspiece are made inactive.
  • the unit includes a pair of spaced-apart columns 1 and 2, a roller table 4 displaceable along a roller way 3 into and out of the space between the columns, and a crosspiece 5 which is detachably supported between the columns and which can be raised and lowered and turned around.
  • lifting yoke 6 On either column there is a lifting yoke 6 having a plane top side provided with a pair of conical guide studs 61.
  • Either lifting yoke is movable along guides 7 by means of a jack 8.
  • the jack is a screw 8' which is borne in the column and coacts with a nut means 8" in the lifting yoke 6.
  • the screws in either column are mechanically connected by means of a transmission shaft 9 and are driven by a common motor 10 via a gearing unit.
  • the screws 8' permitting raising and lowering of the lifting yokes 6 can be rotated not only by means of the motor 10 but also by means of a hand crank 10' via a gear belt drive acting upon the transmission shaft.
  • the hand crank is used when a slow accurate displacement is called for.
  • Each column is provided at its bottom with brackets 13 which constitute supports for one end of two spaced-apart long plane rails 14 which constitute the roller way 3 and are supported against the base at the other end.
  • the roller table 4 is displaceable on the roller way rails 14 which are provided with end stops 15.
  • the roller table has a large number of spherical roller elements 16 which are borne in the roller table and roll on the plane top side of the roller way rails 14.
  • guide rollers 17 which are adapted to engage with the insides of the rails 14. The distance between the outwardly facing portions of the guide rollers 17 is less than the distance between the rails, thus permitting a certain lateral displacement as well as a certain inclination of the roller table 4.
  • Wedge-shaped centering means 14' which engage with the support rollers, are provided at the outer ends of the rails 14.
  • the top side of the roller table is adapted for application of suitable supports, attachments and like means 18.
  • the crosspiece 5 consists of a rigid frame having a downwardly facing side which in lifting position constitutes a fixture 19 with grooves and recesses for screwing on the upper part of the tool to be handled.
  • the crosspiece has projecting abutments 20 and 21 provided with bearing surfaces 23 on both sides.
  • the abutments also have guide openings 24 adapted for the guide studs 6' provided on the lifting yoke 6 of the respective column.
  • a bore 25 serving as a hub
  • a pivot 26 which is axially displaceable at the upper end of the column 2, is insertable into said hub. Said pivot is operated by means of a lockable mechanism 26' adapted to prevent unintentional displacement of the pivot.
  • a turning mechanism comprising a self-locking gearing unit 29 driven by means of a handle 28 and coupled to an axially displaceable driving disc 30.
  • driving disc there are two eccentrically located driving pins 31 adapted to run into the bores 27 at the abutment 21 of the crosspiece. Also the axial displacement of the driving disc is effected by means of a lockable operating unit.
  • the unit according to the invention is used in the following way.
  • the crosspiece is lowered so that its fixture will abut against the upper part B of the tool and be connected therewith by means of screw connections.
  • the upper part B anchored to the crosspiece 5 can then be lifted up by means of the lifting yokes from the lower part of the tool A which resting on the roller table can be pulled out and lifted away for the required steps.
  • Assembling of the tool is effected in the reverse order.
  • the upper tool part is placed on the crosspiece or is placed together with the crosspiece on the roller table which is pushed in between the columns and oriented so that the lifting yokes 6 can engage with the abutments 20 and 21.
  • the crosspiece is lifted by means of the lifting yokes 6 until the pins 26 and 31 can be introduced, whereupon the lifting yokes are lowered so as to allow turning around.
  • After turning around the lifting yokes are again raised into engagement with the abutments and the pivot pins 26 and 31 are moved out of engagement.
  • the lower tool part A has been placed on the roller table and been moved in between the columns so as to be aligned with the upper tool part B.
  • test pressing operations with reduced effect while the upper tool part still is attached to the crosspiece, and this is done by allowing the jacks to displace the upper tool part away from and towards the lower part of the tool which must of course be firmly supported at this stage. If test pressing is to take place the guide studs of the lifting yokes are completed with locking screws which extend through the abutments and bear against the upwardly facing sides thereof.
