Definitions

  • the invention relates to a tool holder with a tool adjustment and an arrangement of such a tool holder and a appropriate tool.
  • the invention relates to the field the tool holder for step presses or similar machines on which a stamp with at least one tool back and forth in one working direction is moved.
  • Such a multi-stage press is known for example from EP 0 354 428 A2 known.
  • This includes a tool holder, in which several Stamps in tool holders on a reciprocating carriage being held. By the back and forth movement the stamp pressed against the corresponding matrices and thereby an between Stamp and die arranged workpiece machined. With every stroke of the slide, the individual workpieces are gripped along a direction of transport from one pair of stamps and dies to the next transported.
  • This change holder includes a change plate in which a wedge is arranged per tool holder, which over a one Intermediate bushing having a tool system, an adjustment of the individual Allows stamp.
  • the individual adjustable Wedges are guided laterally in the removable plate. This happens in particular by guiding the wedges to one another and laterally Limitation of the space accommodating the wedges in the removable plate.
  • the wedge is supported on a wedge rear bearing and can in this way put on it by the stamp over the intermediate piece encounter exercised forces.
  • the invention proposes a tool holder with a Tool adjustment in which at least two tools in one tool holder each are held on a slide, whereby the tool adjustment for each tool an adjustable wedge, a wedge rear bearing, includes a wedge guide and a tool system and such is designed such that adjusting the wedge displaces the tool system into an adjustment device, which is characterized by that each of the two tool holders together with the associated wedge each separately as a structural unit of the carriage is removable.
  • the tool holder and the wedge as one structural unit are removable, they can be much more compact as an assembly be formed. Eliminating otherwise necessary fasteners, Holding plates and the like as well as the resultant Compactness allow the entire tool holder to be essential builds smaller and therefore more space for the stamp and corresponding The slide guide remains.
  • the arrangement also has the advantage that if a wedge during operation is damaged, only the corresponding tool holder needs to be replaced with the wedge. With the known Arrangements must be made for the entire tool holder with the ones still intact Wedges and tool holders can be replaced.
  • the invention proposes a tool holder with a Tool adjustment before, in which a tool in a tool holder is held on a carriage, the tool adjustment an adjustable wedge, a wedge rear bearing, a wedge guide and one Includes tool system and is designed such that an adjustment of the Keils causes the tool system to be shifted in an adjustment direction, which is characterized in that the tool holder and the wedge guide are integrally formed with each other.
  • the one-piece design of tool holder and wedge guide requires a particularly compact design, through which a corresponding Size reduction of the tool holder with those already described above Advantages.
  • the term "tool system” denotes every system or every stop on which a tool which to be held by the tool holder for the purpose of adjustment Facility is coming.
  • the tool holder is a recess, such as, for example, designed as a hollow cylinder or cuboid, into which a tool can be inserted and fastened, so the corresponding tool is pushed into the recess until it is comes into contact with the tool system.
  • relocation the depth of the tool system in the tool Tool holder can be inserted, adjusted so that the opening direction of the recess the corresponding adjustment direction Are defined. It goes without saying that the direction of adjustment also applies to others Chosen way and the relocation take effect in another way can.
  • the wedge guide ensures the fact that the wedge can be adjusted along an adjustment direction is used Wedge rear bearing to do this, most of the on the wedge through the tool to compensate for the forces exerted. It is understood that part the forces also by other locking means, such as the adjusting device for the wedge.
  • the tool holder is particularly compact, even if the wedge rear bearing is integrally formed with the tool holder.
  • This arrangement also has the advantage that the tool holder absorbs the forces of the wedge even when the tool is loaded, so the load on the assembly which side on the slide the tool holder connects, is reduced. In this respect, this can Assembly correspondingly lighter or smaller and thus space-saving be formed.
  • the one-piece connection of the wedge rear bearing enables and tool holder that if the wedge rear bearing is destroyed, which is usually accompanied by a destruction of the wedge by one relatively quick and easy to replace the Tool holder the damaged parts can be replaced.
  • the one-piece training of Tool holder and wedge rear bearing also independent of the one-piece Training of tool holder and wedge guide advantageous is.
  • an interchangeable holder which is detachable with the carriage is connected and on which the tool holders are provided.
  • several tool holders can be attached to one of these Exchange holder can be attached, so that a tool change especially can be done easily.
  • Usually there will be several Tools changed as a group because the workpiece is changed a different sequence of tools is required.
  • the arrangement is particularly space-saving if the change holder is one Exchangeable plate on which the tool holders or the Tool holder is provided. For a tool change needs then only the removable disk to be replaced.
  • the tool holders are detachably attached to the removable plate, so that individual tool holders can also be replaced individually can. This is particularly advantageous in the case of wear.
  • the tool system is covered by a surface of the adjustable wedge formed, so can on an intermediate piece comprising the tool system between the wedge and the tool.
  • the one formed by this Arrangement is cheaper and space-saving than the prior art arrangements.
  • the direction of adjustment along which the wedge is caused is preferred is adjustable by the wedge guide, with an angle ⁇ 90o with respect to the Adjustment direction inclined.
  • appropriate adjustment means for the wedge are placed in an area of the tool holder, that decreases in height.
  • the term "height" is perpendicular to Understand stamp axis. This area is usually easily accessible and must also be provided for every tool holder, so that no additional installation space is required for the adjustment means. To that extent is another by such an angle deviating from 90o Space reduction possible. It is understood that the angle between Direction of adjustment and direction of adjustment, which this space reduction enables, regardless of the other features of the tool holder is advantageous.
  • the tool holder comprises a tool holder 1, which has a Removable plate 2 is connected to a carriage 3. On the removable plate 2, several tool holders can also be provided.
  • the tool holder has a bore 4 as a tool holder.
  • a tool can be inserted into this tool holder 4 and then for example by means of a screw 5 as a tool attachment be fixed.
  • the tool holder 1 also has a further bore 6 in which a cylindrical wedge 7 is inserted.
  • the cylindrical one Wedge is made from a thread 8 by means of an adjusting device, Nuts 9 and a support plate supported on the edge of the bore 6 10 held in place.
  • the wedge 7 also has a tool system 11 as a wedge surface and is supported with its side opposite the tool system 11 on a wedge rear bearing 12. As can be seen immediately Wedge rear bearing 12 and a wedge guide defining the adjustment path of the wedge 7 13 formed by the bore 6.
  • the wedge system is in this embodiment force-free with regard to the removable plate. This allows dynamic Alternating loads, such as suspensions or strains, be caught by the closed system of the tool holder. This requires a higher durability. This creates a parting line avoided, the tool attachment is also more stable than when standing of the technique.
  • this arrangement protects the slide itself, since the removable plate 2 is not affected, if the wedge 7 damages its guide in the event of breakage.
  • the holes 4 and 6 and the tool system 11 designed such that the tool system 11 is at right angles is aligned with the tool holder 4.
  • the central axis is determined accordingly 15 of the bore 6, the direction of adjustment, along which the wedge 7 is adjustable is.
  • the wedge 7 also has an elongated hole in this embodiment 16, through which an optional stamp ejector can be used 17 by a tool provided in the tool holder 4 Stamp can be used to eject a workpiece can.
