Definitions

  • the invention relates to a device for feeding electrical contact elements into the crimping tools of a crimping press, the contact elements being fed in the form of a strip material, in which they are lined up next to one another via scrap webs standardized at least in-house.
  • a feed device enables the step-by-step feeding of electrical contact elements, which are produced in the form of strip goods and are wound on spools, into the crimping tool of a crimping machine.
  • a crimped contact element is separated from the tape after crimping or at the same time as crimping with a cutting knife.
  • the individual contact elements are connected to one another via scrap webs of defined length and width.
  • the contact elements are fed to the crimping tools in the so-called cross transport.
  • the contact elements are usually fed in using a transport finger.
  • the transport finger is actuated by a lever device when the upper punch of the crimping tool moves down. He takes z. B. behind an edge of a contact element and pushes the tape towards the crimping tool.
  • the frictional forces of a transport brake acting on the tape must also be overcome.
  • the transport brake serves to prevent the kinetic energy generated and stored by the high acceleration of the tape or the reel from being converted into an uncontrolled advancement.
  • the transport brake exerts a pressing force which, in the case of relatively small miniaturized contact elements which are made of a correspondingly thin material, must not cause any deformation.
  • the braking force must not be reduced so much that the transport movements become uneven.
  • the contact elements After crimping, when moving the transport finger backwards, the contact elements must not be brought along by friction, since otherwise the contact elements will be inaccurately positioned and the finger will not be able to reach behind the edge provided for this purpose. If in such a case there is a disturbed transport movement, the finger hits the edge, so that the transport is jerky and the contact elements are not conveyed under the crimping dies precisely enough. During the subsequent crimping process, this can lead to pressure peaks between the crimping tools and thus damage or even breakage of the crimping dies.
  • the object of the invention is to provide a feed device in the transverse transport, which ensures a precise placement of adjacent contact elements in the crimping tools and which requires little space.
  • a strip product 1 (see FIG. 5) is transported, in which contact elements 3 are connected to a scrap strip 2 via a short scrap web (not recognizable).
  • the contact elements 3 are connected to the scrap strip 2 in such a way that the longitudinal axis 4 of their longitudinal extent lies perpendicular to the longitudinal axis 5 of the scrap strip 2 in the plane of the strip, the contact elements 3 being arranged next to one another at the same distance "a".
  • rectangular driving windows or driving holes 6 are punched out in the tape direction at the same distance "a" from one another, as is known per se.
  • the essential components of the feed device according to the invention are mounted on a table top 7 which is detachably arranged on the press table of a crimping press (not shown) (see FIG. 1).
  • a crimping press Of the crimping press, only the tool head 9 moved vertically in the double arrow direction 8 from the plunger of the crimping press to crimping is shown.
  • the plunger of the crimping press is releasably attached to the driving head screw 10 of the tool head 9, the tool head 9 carrying the upper punches 15 of the crimping tools.
  • the lower punches are arranged in the press table and not in the drawing recognizable because they are covered by components of the feed device. Due to the detachable arrangement in each case, the table top 7 together with the feed device including the tool head 9 mounted thereon can be removed or replaced from the crimping press.
  • the feed device according to the invention has, as essential components, the transport finger actuation device 11 (FIG. 2), the transport finger displacement device 12 (FIG. 3), the transport finger positioning device 13 (FIG. 4) and the retraction lock 14 (FIG. 5).
  • the feed device according to the invention has the task of pushing each contact element 3 in a positionally accurate manner under the upper punches 15 or between the punches of the crimping tool by means of a gradual advance in the transverse transport in the transport direction 15 a.
  • the transport finger actuation device 11 serves to pull the transport finger 16 downward out of a driving hole 6 of the scrap strip 2 and to push it into the next driving hole 6 from below.
  • the transport finger 16 is underfloor for this purpose, i.e. arranged below the scrap strip 2 in the feed device according to the invention. It is provided on a vertically aligned plate 17 in one piece upwards, which is fastened on a bearing block 21 which is pivotably seated in a recess 18 of a transport carriage 19 about a horizontal axis 20 lying parallel to the transport direction 15a.
  • the transport finger 16 protrudes out of the recess 18 upwards.
  • the transport carriage 19 is horizontally displaceable in the double arrow direction 23 on two side by side and parallel to the transport direction 15 a arranged cylindrical slide rods 24, 25, which pass through holes (not shown) in the transport carriage 19 in a form-fitting manner.
  • the slide rod 24 is pivotally supported in the double arrow direction 33 at one end in a bearing block 26 arranged downstream of the crimping die 15 in the transport direction 15a, firmly seated on the table top 7, and pivotable at the other end in a bearing block which is also firmly seated on the table top 7 and the crimping die 15 upstream in the transport direction 15a 27, the bearing block 27 being part of the transport finger positioning device 13.
  • the substantially horizontal transport slide 19 is - viewed in plan view - L-shaped, the L-base web 19 a being penetrated by the slide rod 24 and the L-leg 19 b approximately in the middle of its extension by the shorter slide rod 25.
  • the slide rod 25 is carried by the slide rod 24 by a cross member arm 28 in the area of the bearing block 27 or the transport finger positioning device 13 and a cross member arm 29 in the area of the bearing block 26 and firmly seated on the slide bar 25 and the slide bar 24 with its respective end area in the respective cross member is stuck.
  • two adjustable stop pieces 30, 31, clamped on the slide rod 25, are adjustable, of which one stop piece 31 in the transport direction 15 a in front of the L-leg 19 b and the other stop piece 30 in the transport direction 15 a behind the L- Leg 19 b are arranged.
  • the stop pieces 30, 31 limit the movement stroke of the transport block 19 in the double arrow direction 23.
  • a vertically upward connecting tab 32 is provided, the task of which will be described below.
  • an upwardly directed lever arm 29 a is integrally connected to the cross member arm 29, so that the cross member arm 29 and the lever arm 29 a are L-shaped, about the axis 24 a of the slide rod 24 in the double arrow direction 39 as a result of Bearings in the bearing blocks 26, 27 result in tiltable lever 34.
  • the rocker arm 34 is actuated by a roller 35 against which the lever arm 29 a is pressed with its front edge 34 a by a compression spring 36 which acts against the rear edge of the lever arm 29 a.
  • the roller 35 is rotatably supported in a carrying fork 37, which sits firmly on the outside on a wall 38 a of the tool head housing 38 and thus follows the movement of the tool head 9 in the double arrow direction 8.
  • the front edge 34 a of the rocker arm 34 is equipped with a projection 34 b in the upper end region of the lever arm 29 a, so that the roller 35, when it rolls over the projection 34 b during the downward stroke of the tool head, the rocker arm 29 a moved against the spring 36.
  • the reverse movement takes place, i.e. the transport finger 16 is pulled down.
  • the transport finger 16 which indeed makes a movement along the circular arc path 22, remains vertically aligned due to the pivotable mounting about the axis 20.
  • the transport carriage 19 is most expediently driven with the transport finger displacement device 12 according to FIG. 3. It has a push rod 40 which is articulated at one end on the connecting bracket 32 of the transport carriage 19 and points in the direction of the rocker arm 34 and which is articulated at the lower end of a rocker arm 41, which protrudes upwards and is pivotably supported at another end about an axis 42 on a fixed part of the crimping press (not shown). Approximately in the longitudinal center of the rocker arm 41, the piston rod 43 is articulated to a piston cylinder arrangement 44 which is fixedly arranged in the crimping press. A back and forth movement of the piston rod 43 parallel to the double arrow direction 23 moves the transport carriage 19 from one stop piece 30 to the other stop piece 31 or vice versa. The transport finger 16 is moved in the double arrow direction 23 by the same path.
  • the pushing movement of the transport finger 16 must be combined with its immersion or surfacing movement caused by the rocker arm 34 in such a way that the transport finger 16 submerses or appears shortly before the onset of the respective pushing movement.
  • This is expediently done with a switching device 45 according to FIG. 3.
  • the switching device 45 is provided at the upper free end of the lever arm 29 a, a switching pin 46 pointing in the direction of the piston-cylinder arrangement 44, which is arranged from the side, being arranged at the upper free end of the lever arm 29 a forth in a U-shaped recess 47 of a slide plate 48 slidable horizontally in a groove 49.
  • the groove 49 is arranged frontally in a switch housing 50 mounted in the crimping press, in which a z. B.
  • the width of the U-shaped recess 47 in the switching slide plate 48 is larger. than the diameter of the switching pin 46, so that the switching pin 46 actuates the slide plate 48 only after a certain idle stroke when the respective tilting movement of the rocker arm 34 begins.
  • the slide rod 24 with the parts attached to it can be adjusted with the transport finger positioning device 13 in its axial direction (double arrow direction 52) (FIG. 4).
  • This fine adjustment provides that the bearing block 27 in the transport direction 15 a at a distance downstream of another bearing block 27 a is arranged on the table top 7, which is responsible for the actual rotatable mounting of the slide rod 24, with the space between the blocks 27, 27 a a clamping piece 27 b with a clamping screw 27 c sits on the free end of the slide rod 24.
  • the slide rod 24 is extended by an adjusting screw 24 a, which is in the free end region of the slide rod 24, the slide rod 24 ending immediately in front of the bearing block 27.
  • the set screw 24 a has an external thread which is guided in an internal thread in the end region of the slide rod 24 (not shown), the shaft 24 c of the set screw 24 a passing through a bore 27 d in the bearing block 27 and the head 24 b of the screw 24 a protrudes outwards from the bearing block 27.
  • the bore 27 d is larger in diameter than the diameter of the screw shank 24 c, and also accommodates a compression spring 24 d that surrounds the shank 24 c, which rests against a bore step 27 e in the bearing block 27 provided near the screw head and at one end against one at the end of the slide rod 24 provided 24 e supports.
  • the clamping screw 27 c is loosened.
  • the adjusting screw 24 a which rests on the bearing block 27 by the spring force, the position of the slide rod 24 together with the stops is adjusted. Then the clamping screw 27 c is tightened again.
  • the retraction lock 14 is located in the band goods inlet area of the feed device. It has an L-shaped angle block 53, the horizontal L-base web 53 a overlaps the scrap strip 2 and the vertical L-leg 53 b protrudes downward.
  • the L-leg 53 b laterally opposite a bearing plate 54 is provided under the contact elements 3, which supports an upright stopper arm 55 pivoted about an axis 56, which is arranged in the space between the bearing plate 54 and the L-leg 53 b below the scrap strip 2 is.
  • the stopper arm 55 is inclined in the transport direction 15 a; its upper free end presses from below against the scrap strip 2 and thus the scrap strip 2 against the L-base web 53 a, which is caused by a compression spring 58 which is supported at one end against the stopper arm 55 against its inclination and at the other end on the bearing plate 54.
  • the lower end of the stop arm 55 protrudes downward from the space between the L-leg 53 b and the bearing plate 54 and has an actuating pin 57 with which the stop arm 55 can be pivoted by hand.
  • the stopper arm 55 thus acts in the manner of a holding wedge which is constantly in contact with the transport or scrap strip 2 and prevents the strip material from being retracted by means of the self-locking. By pulling the pin 54 against the direction of transport and against the spring force, the clamping can be released so that the tape can be removed and / or moved.
  • the scrap strip is guided between two superimposed guide webs 59 and 60, as is known per se, the guide web 60 being arranged so that it can be folded away, so that the strip product is inserted into the feed device or can be removed from the feed device.
