Definitions

  • the invention relates to a crimping press for producing a crimp connection by means of an upper tool and a lower tool, wherein the upper tool with a linear movement crimps a auflegbaren on the lower tool crimp contact with a conductor end.
  • a crimping press has become known, on the stator of which an engine and a transmission are arranged.
  • first guides are arranged on the stand on which a crimping rod is guided.
  • a driven by the gear shaft has at one end an eccentric, on the other hand, a resolver is coupled to detect the angle of rotation.
  • the Crimpbär consists of a guided in the first guides slider and a tool holder with force sensor and holding fork.
  • the slider is in loose connection with the eccentric pin, wherein the rotational movement of the eccentric pin is converted into a linear movement of the slider.
  • the maximum stroke of the slider is determined by the top dead center and the bottom dead center of the eccentric pin.
  • the tool holder actuates a tool which, together with a tool belonging to the anvil makes the crimped connection.
  • the tool has a guided in a tool housing punch carrier with carrier head, which is in loose connection with the holding fork of the tool holder.
  • At Stempelisme are a first Crimping die and a second crimping die arranged, which together with the correspondingly formed anvil make the crimp connections.
  • a disadvantage of the known device is that the guided in the tool housing punch carrier forces caused by friction or additional forces can be caused by tilting, the forces distort the measurement of the crimping force.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1, solves the problem of avoiding the disadvantages of the known device and to provide a crimping press, the upper tool causes no frictional forces caused by guides.
  • the upper tool with crimping die is a unit which can be attached directly to the press carriage.
  • the lower tool with anvil and contact feed, the contact roller and the contact feeder are combined in a cassette, which is interchangeable as a drawer.
  • the crimp contacts are supplied to the crimping tool arcuately, whereby the crimping press builds narrow.
  • the space requirement in the width for a crimping press is approximately halved and the changeover time significantly reduced. Due to the mechanical separation of the upper tool from the lower tool, the contact belt no longer has to be run out.
  • the crimp height can be programmed (variable bottom dead center). This also eliminates the manual adjustment of the crimp height of the Crimping tool, as it is necessary with conventional tools.
  • a force measuring device for the crimp force monitoring is integrated in the upper tool holder of the press carriage.
  • this force measuring device must be installed above the coupling between press slide and tool or under the base plate of the tool.
  • other forces contact feed, cutting forces for separating the contact from the carrier strip, friction, jamming, etc.
  • the crimping press concept according to the invention exclusively measures the forces relevant for the assessment of the quality of the crimping.
  • Fig. 1 and Fig. 2 show the crimping press CR according to the invention, wherein Fig. 2 shows the crimping press CR with removed cassette KA and with removed upper tool OW.
  • An engine MO drives a transmission GE.
  • an eccentric device is provided, which converts the rotational movement of the motor MO and gear GE into a transferable to a press carriage 11 linear up / down movement, wherein the press carriage 11 is guided by guides FÜ.
  • FIG. 3 and FIG. 4 show details of the upper tool OW, which includes the wear parts such as wire crimper 1, insulation crimper 2 and knife ram 3. Depending on the crimp contact to be processed, additional wear parts and spacer plates may be necessary.
  • the wire crimper 1 is firmly screwed to a holder 4, the remaining wear parts used and the upper tool OW closed with a front panel 5.
  • a spacer 6 is interchangeable for adjusting the insulation crimp height.
  • the knife ram 3 with extension 3.1 is mounted vertically movable in the upper tool OW, wherein the dimensions of an elongated hole 7 limits the movement.
  • a recess 11.1 is provided, in which an eccentric of the eccentric engages, wherein the rotational movement of the eccentric pin is converted into a linear up / down movement of the press carriage 11.
  • the upper tool OW is manually inserted into a tool holder 10 arranged at the lower end of the press carriage 11 and held on a pin 13 by means of a bolt 12.
  • the pressed-up by means of compression springs 12.1 latch is pressed at a tool change by means of an extendable piston 14 down.
  • the piston 14 must be extended and the press carriage 11 perform a vertical movement upward.
  • Fig. 6 shows the inserted into the fork-shaped tool holder 10 upper tool OW, the upper tool OW is held by means of a lower fork 10.1 and 10.2 by means of an upper fork.
  • the knife ram 3 is operated during crimping a knife 41 of a lower tool UW, with which knife 41 a crimp contact 20 is separated from a carrier strip 21 and the carrier strip 21 is crushed.
  • the forces occurring do not flow through the force sensor device 16, since the Blade ram 3 in the upper tool OW is vertically movable and with its extension 3.1 rests directly on the body 22 of the press carriage 11.
  • insertable from the back of the crimping press CR fro cassette KA comprises a contact roller 30, which stores the supply of strapped crimp contacts 20.
  • a contact belt KO wraps around a tensioning roller 32 and is guided arcuately 90 ° turned onto the lower tool UW.
  • a TextilstMailschreibwickler 34 is driven via a gear from a placed in the crimping press CR mating.
  • Both sides arranged and sprung in the vertical direction mounted guide rails 33 are used to insert the cassette KA in the crimping press CR cassette change, the guide rails 33 are guided in guides 33.1 of the crimping press CR.
  • the cassette KA is pneumatically and electrically connected to the crimping press CR with a quick-change connector 36.
  • Fig. 7, Fig. 8 and Fig. 9 show details of the lower tool UW consisting of a vertical knife guide 40, a knife 41 for separating the crimp contacts 20 from the carrier strip 21 and for crushing the carrier strip 21, an anvil 42 for making a crimp and a contact pad 43 for guiding the crimp contacts 20.
  • the crushed Carrier strip 21 falls into the waste pipe 44.
  • the advance of the crimp contacts 20 is performed by a pivoting movement of a feed finger 45.
  • the two End positions of the pivoting movement can be determined with the adjusting screws 46.1, which determine the end positions of a pneumatic feed drive 46.
  • the deflection and guidance of the contact belt KO during feed is achieved by the guide members 47.
  • These guide parts 47 are adjustable as a whole in the cable direction, so that the position of the crimp contact 20 on the lower tool UW or on the anvil 42 can be determined exactly.
  • the crimp connection is produced by means of the upper tool OW and the lower tool UW, wherein the upper tool OW crimps with a linear movement auflegbaren on the lower tool UW crimp contact 20 with a conductor end LE. Details are in Fig. 9 shown.
  • the crimp contact 20 connected to the carrier strip 21 has tabs 20.1 for the wire crimp and tabs 20.2 for the insulation crimp, the tabs 20.1, 20.2 being plastically deformed by means of wire crimpers 1 or by means of insulation crimps 2 and after the crimping process the wire LD or the insulation Firmly embrace LI.
  • the knife 41 for separating the crimp contact 20 from the carrier strip 21 consists of a slide 41.1 with knife edge 41.2 and a fixed knife block 41.3 with spring 41.4, wherein during the crimping of the knife ram 3, the slide 41.1 moves against the spring force of the spring 41.4 down and the crimp contact 20th by means of the knife edge 41.2 and by means of a knife edge 42.1 of the anvil 42 separated.
  • Fig. 10 . 11 and FIG. 12 show details of the arranged at the lower end of the press carriage 11 tool holder 10 with the force sensor device 16.
  • the forces resulting from the crimping process are passed from the bearing surfaces 15 of the upper tool OW at several points to the force sensor device 16.
  • two sleeves 16.2 held by screws 16.1 are provided on the upper fork 10.2 on each side, the crimping forces being transmitted on each side of the support surface 15 to the two sleeves 16.2.
  • Each side can also be provided more or less than two sleeves 16.2.
  • the screws 16.1 hold with the head part of the sleeves 16.2, the other end, the screws 16.1 are screwed to the press carriage 11.
