Definitions
- the invention relates to a carriage of a press with a tool holder with a tool adjustment and an arrangement of such a carriage and a appropriate tool.
- the invention relates to the field the slide in step presses or similar machines, in which a stamp with at least one tool back and forth in one direction is moved.
- Such a multi-stage press is known for example from EP 0 354 428 A2, which also forms the basis for the preamble of the claims 1 and 2 forms.
- This includes a tool holder, in which several Stamp in tool holders to a reciprocating slide being held. By the float, the stamps become pressed against corresponding matrices and thereby a between Stamp and die arranged workpiece processed. With every stroke of the carriage, the individual workpieces along with grippers along a transport direction from one stamp-die pair to the next transported.
- This change holder comprises a removable plate, in which per tool holder a wedge is arranged, which has a one Tooling having intermediate bush an adjustment of the individual Stamp allows.
- the single adjustable Wedges are guided laterally in the removable plate. This happens in particular by a guidance of the wedges with each other and a lateral Limiting the wedges receiving space in the removable disk.
- the wedge is supported by a wedge-shaped rear bearing and This way you can put it on the punch through the intermediate piece encountered forces.
- the invention proposes on the one hand a carriage of a press with a tool holder with a Tool adjustment before, in which at least two tools in each of a tool holder can be held on the carriage, wherein the tool adjustment per tool an adjustable wedge, a wedge rear bearing, a wedge guide and a tool system includes and so is formed, that an adjustment of the wedge a displacement of the tool system effected in an adjusting device, which is characterized by that each of the at least 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 a structural unit are removable, they can be much more compact than an assembly be formed.
- the renunciation of otherwise necessary fasteners, Holding plates and the like and the resulting Compactness allow the entire tool holder to be essential smaller builds and thus more space for the stamp and corresponding Slide guide remains.
- the arrangement also has the advantage that if a wedge during the operation is damaged, only the corresponding tool holder needs to be replaced with the wedge. In the known Arrangements must each be the entire tool holder with the still intact Wedges and tool holders are replaced.
- the invention proposes a carriage of a press with a tool holder with a Tool adjustment in which a tool in a tool holder can be held on the carriage, the tool adjustment an adjustable wedge, a wedge rear bearing, a wedge guide and a Includes tool and is designed such that an adjustment of the Wedge causes a displacement of the tool installation 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 the already described above Benefits is made possible.
- the term "tool installation" each plant or each stop to which a tool, which is to be held by the tool holder for the purpose of adjustment for Plant comes.
- the tool holder as a recess, such as hollow cylinder or hollow cuboid, designed, in which a tool can be inserted and fixed in it, so the corresponding tool is pushed into the recess until it comes to the tool plant to the plant.
- the adjustment direction also applies to others Chosen way and the shift in another way take effect can.
- the wedge guide ensures that the wedge is guided guided along an adjustment, this serves Wedge back bearing to do most of the on the wedge through the tool compensate for the forces exerted. It is understood that a part the forces also by further locking means, such as the adjustment for the wedge, can be included.
- the tool holder is particularly compact, even if the wedge-shaped rear bearing is formed integrally with the tool holder.
- This arrangement has the additional advantage that thereby the tool holder even when the tool is loaded, the forces of the wedge are absorbed by it, so that the load on the assembly, which slide side the tool holder connects, is reduced. Insofar, this can Assembly accordingly lighter or smaller and thus space-saving be formed.
- the one-piece connection enables wedge-shaped rear bearings and tool holder, that upon destruction of the wedge support, which is usually accompanied by a destruction of the wedge, by a relatively quick and easy to carry out the exchange Tool holder the damaged parts can be replaced. This especially in connection with machines which have several Have tool holders. In such machines then needs just replaced the tool holder with the defective wedge rear bearing become. It is understood that the one-piece training of Tool holder and wedge support also independent of the one-piece Training tool holder and wedge guide advantageous is.
- a change holder which releasably connected to the carriage is connected and on which the tool holders are provided.
- a plurality of tool holders may be attached to such Removable holder be attached so that a tool change especially can be easily done.
- several will be Tools changed as a group, as when changing the workpiece a correspondingly different sequence of tools is needed.
- the arrangement is particularly space-saving, when the change holder a Removable plate comprises, on which the tool holders or the Tool holder is provided. For a tool change needs then only to be replaced the removable disk.
- the tool holders are detachably attached to the removable plate, so that individual tool holders are also exchanged individually can. This is particularly advantageous when worn.
- the adjustment, along which the wedge conditional is adjustable by the wedge guide, with an angle ⁇ 90o with respect to the Adjustment direction inclined.
- appropriate adjustment for the wedge to be placed in an area of the tool holder, which decreases in height.
- the term "height" is perpendicular to Stamp axis to understand. This area is usually easily accessible and must also be provided with each tool holder, so that no additional space is needed for the adjustment. insofar is another by another such 90o angle Space reduction possible. It is understood that the angle between Adjustment and adjustment, which this space reduction allows, 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. At the removable plate 2 can also be provided several tool holders.
- the tool holder has a bore 4 as a tool holder.
- a tool can be inserted 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 by means of an adjustment of a thread 8, Nuts 9 and at the edge of the bore 6 supporting support plate 10 held in position.
- the wedge 7 also has a tool attachment 11 as a wedge surface and rests with its side opposite the tooling 11 side on a wedge support 12 from. As immediately apparent that becomes Wedge rear bearing 12 and the adjustment of the wedge 7 defining wedge guide 13 formed by the bore 6.
- the wedge system force-free with regard to the removable plate can be dynamic Alternating loads, such as suspensions or strains, be caught by the closed system of the tool holder. This requires a higher durability. By having a parting line is avoided, the tool attachment is also more stable than in the state of the technique.
- the holes 4 and 6 and the tool system 11 designed such that the tool system 11 at right angles is aligned with the tool holder 4.
- the central axis forms 14 of the tool holder 4 an adjustment direction, along which the tool is adjustable.
- the central axis determines 15 of the bore 6, the adjustment direction along which the wedge 7 adjustable is.
- the wedge 7 also has a slot in this embodiment 16, through which an optional to use stamp-side ejector 17 provided by a tool holder 4 as a tool Stamp can be used to eject a workpiece can.
