Definitions

  • the invention relates to a crimping press according to the preamble of claim 1.
  • Such a crimping press is known from DE 10 2006 041 846 B3. It comprises a clamping plate, a crimping tool with a base plate, which are rigidly connected during normal use. An adapter is connected to the base plate with the aid of first half claws without rigid contact and relatively movably in order to achieve vibration isolation with respect to a memory fixed thereon for the crimp contacts to be processed.
  • the assignment of the base plate to the clamping plate after a tool change is not always as accurate as is desirable. The crimping result can be adversely affected.
  • the invention is based on the object of further developing such a crimping press in such a way that an accurate and exactly reproducible positioning of the crimping tool in the crimping apparatus can be achieved even with frequent tool changes.
  • the adapter for solving this problem is provided at one end with an I - projection and fixed immovably to the base plate with the aid of the first holding claws in the region of the I - projection, wherein the I - projection parallel to its longitudinal direction in a one-sided in the longitudinal direction and in the direction of the base plate open groove of the clamping plate is inserted, wherein the I ⁇ projection in the direction of the base plate has a lower height than the groove, wherein the I - projection a centrally mounted recess having a parallel to the longitudinal direction in the recess projecting retaining cams, wherein the retaining cam with at least a second retaining claw of the clamping plate is engageable and wherein the base plate is pressed by the second retaining claw on both sides of the groove directly to the platen.
  • the adapter thereby fulfills the purpose to position the base plate very accurately with respect to the platen and to press directly adjacent to each other while avoiding intermediate layers. Both in the horizontal direction as well as in the vertical position, this results in a very accurate and reproducible positioning of the crimping tool in the crimping press, which contributes significantly to avoid adjustment work even after a tool change and immediately achieve a perfect crimping result.
  • a particularly firm, vertical compression of the clamping plate and the base plate can be obtained when the retaining cam is provided with a clamping surface arranged inclined to the plane of the platen, wherein the second retaining claw is movable parallel to the plane of the clamping plate and engageable with the inclined clamping surface.
  • the clamping surface is suitably positioned within one of three imaginary, straight connecting lines of the first retaining claws enclosed field, which connect the I-projection with the base plate.
  • the retaining cam can thus be particularly stable statically to the mutual contact surfaces of the base plate and the clamping plate to press together.
  • the profile of the I - projection and the profile of the groove should correspond to each other as far as possible with good Relatiwerschieb sadness.
  • the lateral flank surfaces of the I - projection and the groove should touch each other for this purpose displaced play.
  • the I - projection and the groove may be formed at the end facing the adapter 1.5 to 2 times as wide as at the projecting end.
  • the insertion of the I - projection in the longitudinal direction of the groove is facilitated.
  • the tilting security is improved with respect to the tensioned during the intended use with the I - projection Auf ⁇ pannlatte, which makes it easier to use the adapter for attaching secondary objects, for example, from memories for crimp contacts o.a ..
  • the regions of different width of the I - projection and the groove by at least one inclined surface inclined to be connected in transition.
  • the I - projection and the groove are exactly adapted to each other in terms of shape and size, so that they are easily but shakeproof and play-free inserted into each other. Only in the vertical direction is the groove higher than the I-projection,
  • the I - projection may be extended at the end facing the adapter to a transverse web, wherein two of the first retaining claws respectively the front end of the transverse web, according to facing forward, overlap above and at least a third retaining claw, the front end of the I - projecting, turned backwards, overlaps above.
  • a single, first retaining claw is arranged at the front end of the I - projection.
  • This first retaining claw can be displaceable by a clamping screw in the direction of the other holding claws and be brought into engagement with the associated inclined clamping surfaces of the base plate in order to grasp this forceps like the front and rear end and set immovable.
  • the adapter can be extended to a holder for secondary elements at the end remote from the I - projection. If vibrations can be excited by such secondary elements during the intended use, there is the possibility that the holder and the adapter are connected vibration-isolated. This can be done, for example, that the holder and the adapter during the intended use of the crimping press outside the clamping area of the crimping tool without direct mutual contact loosely connected and are supported completely independent of each other. Secondary elements that tend to generate natural vibrations, during the intended use of the crimping press can also be completely separated from the holder and thus the adapter, in which the loose connection is temporarily canceled.
