Definitions

  • the present invention relates to a multi-stage Forming machine with a last forming station for division of combination parts in at least two good parts, as in the preamble of the independent claim 1 is defined.
  • Multi-stage forming machines in a last forming station Split the combination parts into two good parts e.g. used for the production of ball bearing rings.
  • the generated ones fall Good parts, for example an inner ring and a Outer ring, due to its own weight on one under the forming station arranged slide and slip on this the forming area of the forming machine.
  • Another disadvantage is that the good parts are removed in a disorganized manner become. The production order of the removed Good parts do not result immediately, so quality control and a possible readjustment of the forming machine and eliminating faulty good parts is. This leads to safety parts in particular too many possibly faulty good parts eliminated Need to become. In addition, is in one a separate step sorting the two manufactured Good part types and possibly one for the following Steps suitable alignment of the good parts required.
  • multi-stage forming machines Given the disadvantages of the previously known, described above multi-stage forming machines is the invention based on the following task.
  • the essence of the invention is that a multi-stage Forming machine with a last forming station for division of combination parts in at least two good parts, has at least two good part removal devices, which each have a transfer device for transferring a Good part from the last forming station to the good part discharge device assigned.
  • the transfer devices enable a quick and controlled removal of the good parts from the last forming station. Thanks to the transfer devices, the speed is the forming machine no longer through the Falling speed of the good parts limited. You can also the good parts in one for the subsequent steps appropriate orientation and timed. Controlled removal according to the production order also enables identification of the Good parts, what an exact quality control, a possible one Readjusting the forming machine and exiting faulty good parts considerably facilitated. For example at due to transitions from bars where the combination parts are made defective good parts the resignation on the immediately affected good parts are limited. It is not more necessary, for security reasons all in one particular Period, possibly defective good parts to be eliminated.
  • the good parts can be removed with the Forming machine can also be manufactured more precisely because the good parts not like with the mentioned forming machines of the stand of technology hitting the slide at high speed. Avoiding or at least greatly reducing of surface damage allows the machining allowances to reduce the good parts or even omit them entirely.
  • the multi-stage forming machine shown has three forming stations 1 ", 1 'and 1, being in the last forming station 1 combination parts 2 in two good parts be divided. Can be seen in the last forming station 1 is only one good part 21, here in the form of a Inner ring; the other good part, in the present embodiment an outer ring has already been separated from it and removed.
  • the combination parts 2 are with a pair of pliers 11 'from the forming station 1 "to the forming station 1 'and with pliers 11 from the forming station 1' to the forming station 1 transported.
  • the pliers 11 'and 11 point an upper gripper 111 'or 111 and a lower one Grippers 112 'or 112 on an upper tong holder 12 respectively attached to a lower tong holder 13 are.
  • the cross-feeding of the tongs 11 'and 11 takes place by moving the tong holder 12 and 13.
  • a good part removal device is for removing one good part 21 3 is provided, which is a transfer device 5 to transfer the good part 21 from the last forming station 1 is assigned to the good part removal device 3.
  • the good part removal device 3 comprises one of two side walls, of which only the side wall 32 can be seen here is limited, obliquely arranged slide 31 on which the Good parts 21 slip out of the forming area of the forming machine.
  • the transfer device 5 has a transfer pliers 51 an upper gripper 52 and a lower gripper 53, the rotatable on the upper tong holder 12 or on the lower tong holder 13 are rigidly attached and by means of these two Pliers carrier from the last forming station 1 to the good part removal device 3 and vice versa.
  • a Screw 56 acts as an adjustable stop for the upper one Gripper 52.
  • a good part 21 is adjustable by means of two Gripping jaws 521, 522 of the upper gripper 52 from above and by means of an adjustable gripper jaw 531 of the lower gripper 53 held from below. That of the good part removal device 3 facing side of the gripped good part 21 is free, so that the good part 21 can be placed on the slide 31, without the transfer pliers 51 touching them.
  • the good part 21 with closed threading pliers 51 a certain preload is the upper one Gripper 52 with a biasing spring 54 in the gripping direction biased.
  • a pre-opening device provided the upper gripper 52nd shortly before reaching the good part removal device 3 moved a certain distance in the opening direction.
  • the pre-opening facility in the present case includes an am Anvil 8 attached ramp 55 on which a pre-opening screw 58, which is arranged in a on the upper gripper 52 Mounting plate 57 is screwed, can open.
  • a pre-opening screw 58 is the pre-opening distance of the upper gripper 52 adjustable.
  • the transfer pliers 51 is in the good part removal device side Extreme position and with 9 the machine body designated.
  • the good part unloading part shown here according to the invention Forming machine comprises a first transfer device with a transfer forceps according to FIG. 1, from which For reasons of clarity, only the visible gripping jaws 521, 522 and 531 are drawn, one of the first transfer devices assigned first good part removal device 3, a second transfer device 6 and one assigned to it second good part removal device 4.
  • the first good part removal device 3 is constructed similarly like the good part removal device shown in FIG. 1. The only difference is that the slide 31 has a longitudinally displaceable end part 311. This end part 311 is used to hold smaller good parts 21 moved towards the last forming station 1, see above that even small good parts 21 through the transfer pliers be put on that they slide down the slide 31.
  • Mounting brackets 93 and 94 are used for mounting the good part removal device 3 on the machine body 9 or on Anvil 8.
  • the second good part removal device 4 comprises one of two Side walls 42 and 43 limited, obliquely arranged slide 41, on which the good parts 22, here in the form of outer rings, slip out of the forming area of the forming machine.
  • Mounting brackets 91 and 92 are used for mounting the good part removal device 4 on the machine body 9 or on the anvil 8.
  • the transfer device 6 for transferring a good part 22 from the last forming station 1 to the good part removal device 4 comprises one between the last forming station 1 and the good part removal device 4 arranged slideway 61 for receiving a good part 22 from the last forming station 1 and a pushing device for pushing one on the slideway 61 located good part 22 on the slide 41 of the good part removal device 4.
  • the pushing device in the present case has a kick lever 62 which is on a fixed part 65 is arranged to be pivotable about an axis of rotation 64 is.
  • the fixed part 65 is connected to an anchoring part 63 attached to a stripper 82 (see below).
  • the transfer of the good parts 21 and 22 from the last forming station 1 to the good part removal devices 3 and 4 can be done simultaneously or at different times.
  • a stamp 83 in a die 80 is the retraction of the stamp 83 that Good part 22 pulled out of the die 80 and on the stripper 82 stripped from the stamp 83 and thus reaches the Track 61.
  • the good part 21 is by means of an ejector 81 pushed out of the die 80 and either goes directly in the closed transfer pliers or is from the closing transfer forceps gripped. Then the Transfer of the good parts 21 and 22 as described above the good part removal devices 3 and 4.
  • the present good part unloading part of an inventive one Forming machine differs from that in Figs. 2-5 represented by the fact that it instead of a transfer device 6 with a kick lever 62, a transfer device 7 with a slide 72.
  • the slider 72 will via a drive attachment point 722, e.g. from the upper tong holder 12 of the forming machine, driven and pushes with a sliding plate 721 one resting on the slideway 71 Good part with the speed of the upper tong holder on the slide 41 of the good part removal device 4.
  • the slide movement becomes the slide 72 of guided a carriage 73, which it can be moved vertically penetrates.
  • the carriage 73 itself is guided by a carriage 74 with a T-shaped guide part 75 worn and for this purpose has a T-shaped groove.
  • Guide part 75 and Nut can of course also be done differently be formed, for example dovetail-shaped, trapezoidal etc.
  • the slide guide 74 is over a Anchoring part 76 on scraper 82, which is not visible here attached.
  • the vertical displacement of the slide 72 in the carriage 73 enables this after reaching the good part removal device Extreme position to raise in the reverse extreme position without that the stamp of the last forming station is touched, and then lower back to the starting position.
  • the transfer device 7 with slide 72 has compared to the Transfer device 6 with kick lever 62 has the advantage that the good parts are moved relatively gently and no on them Blow is exercised.
