Definitions

  • the invention relates to a method for loading and unloading rotationally drivable dies for axial die rolling, the forging blank being conveyed up on a conveyor track and fed to the die and being removed and removed therefrom after the axial die rolling.
  • the invention relates to a device for carrying out the method according to claim 1 or one or more of the following claims, with an axial die rolling machine with a die that can be driven in a motor-rotating manner, at least one loading and unloading device each with a loading and unloading tongs for gripping, Lifting and swiveling as well as depositing the forged blank or the finished formed workpiece.
  • the invention has for its object to first improve a method for loading and unloading rotatably drivable dies in axial die rolling according to the type required in claim 1 in such a way that the cycle times are shortened, the wear on the drive units is reduced and the energy consumption is reduced.
  • the invention is based on the object of providing an advantageous die-rolling machine for carrying out this method, which allows the method according to the invention to be carried out economically with simple, robust means.
  • the forging blank is introduced into the motor-driven, that is to say rotating, die so that it no longer needs to be braked to a standstill.
  • the loading device takes over the forging blank from a conveyor belt. If it is forged blanks with an inner bore, they are gripped on the inside. For forged blanks without a center hole, these are gripped on the outside. For example, the loading device is immersed in the forged blank for gripping.
  • the outer diameter is checked at the same time. If the diameter is too large, the forging blank in question is removed. If the specified tolerances are correct, the forging blank is raised and swiveled until it is vertically above the lower die of the die rolling machine. Then the loading tongs are immersed in the running die.
  • a suitable motor drive e.g. B. a gripping cylinder (piston-cylinder unit)
  • the forging blank is released and falls into the rotating lower die.
  • An axial die rolling machine has a loading and unloading tongs and consists of a few robust and therefore reliably functioning parts.
  • the synchronously driven grippers provided for this purpose enable a central internal or external gripping of ring-shaped parts.
  • Claim 7 describes advantageous tongs for loading rotatably drivable dies in the case of external gripping of parts, while claim 8 contains such a construction for internal gripping.
  • claim 9 contains a robust and functioning with few structural parts device for unloading the forgings from the die.
  • the reference numeral 1 denotes a motor-driven conveyor, which can be designed as a continuous conveyor or as an intermittently driven conveyor by means of which forging blanks, not shown here, are conveyed in direction X.
  • the one on the Conveyor 1 forged blanks are removed from the conveyor 1 by a loading device 2 and brought to an axial die-rolling machine, which is only indicated schematically in FIG. 1 and is designated by the reference number 3 as a whole.
  • the loading device 2 can perform a pivoting movement on the trajectory Y.
  • This loading device 2 is assigned a loading tongs 4, which can pick up a workpiece that is brought up on the conveyor 1, pivot it and feed it to a lower die 5.
  • the pivot center of the loading device 2 is designated 6 (Fig. 1).
  • the loading tongs 4 are assigned a gripping cylinder 7 (piston-cylinder unit) which can be acted upon alternately on both sides with pressure medium pressure, in particular with hydraulic oil, the piston rod 8 of which is connected to an actuating rod 9 in a gearbox, for example by a clutch.
  • the confirmation rod 9 is connected to a suitable gear means, for example a toothed rack, as will be explained in more detail in connection with a removal tongs to be described in connection with FIG. 11.
  • a suitable gear means for example a toothed rack, as will be explained in more detail in connection with a removal tongs to be described in connection with FIG. 11.
  • This rack actuates a pinion, not shown in FIGS.
  • the actuating rod 9 is moved in direction A, whereupon the gripping eccentrics 10, 11 and 12 move outwards to a larger diameter and thereby non-positively against the wall of the inner bore or inner recess for contact with the system arrive (Fig. 2, 3), so that the forging blank 13 is removed from the conveyor belt 1, pivoted into the correct position via the loading device 2 and placed in the lower die 5, which is always driven by a motor can.
  • the loading tongs 4 are thus immersed in forging blanks 13 provided with an inner bore or an inner recess, the outer diameter of the forging blank 13 being checked at the same time. If the diameter is too large, the forging blank 13 is eliminated.
  • the forging blank 13 is raised and pivoted by the conveyor 1 until it stands vertically above the rotating lower die 5 driven by a motor. Then the loading tongs 4 are immersed in the running lower die 5. By actuating the gripping cylinder 7, the gripping eccentrics 10, 11 and 12 are pivoted and the forging blank 13 falls into the rotating lower die 5. The forging blank 13 is guided inside and outside in all embodiments during the entire loading process. The forging blank 13 is then formed by lowering the upper slide. When the carriage has been moved up again after the shaping process has ended, an unloading device, designated overall by reference numeral 15, is pivoted in. The unloading device 15 is arranged to be pivotable about the pivot center 16.
  • the formed forging 13 turns on the path curve Z into an intermittent or continuous conveyor 17 which is also motorized like the conveyor 1 is driven, moved and placed on it.
  • 6 and 7 for forged parts 13 provided with inner bores or inner recesses.
  • the unloading device 15 like the loading device 2
  • An actuating rod 19 is also assigned to the unloading tongs 18 and is operatively connected to a piston rod 20 of a gripping cylinder 21 (piston-cylinder unit).
  • the piston rod 20 and the actuating rod 19 can be connected in one piece in terms of function or material, just like in the loading tongs 2.
  • the piston rod 20 and thus also the actuating rod 19 can be moved in the direction C or D by appropriate pressurization of the gripping cylinder 21.
  • the actuating rod 19 in turn grips eccentric 22, 23 and 24 in synchronous motor fashion, which are able to engage under the finished formed workpiece 13 with eccentric levers 25, 26 and 27, respectively, when it has been lifted out of the lower die 5 by an ejector 28.
  • the unloading pliers 18 with their gripping eccentrics 22, 23 and 24 are immersed in the forged part 13, whereupon by applying pressure accordingly the eccentrics 22, 23 and 24 are pivoted outwards (FIGS. 6 and 7), whereupon the unloading tongs 18 lift the completely formed ring 13 and pivot it to the conveyor 17 and can deposit it there.
  • the loading tongs 2 are equipped with three gripping eccentrics 30, 31 and 32, which in turn are driven by a gripping cylinder 7 with a piston rod 8 and an actuating rod 9.
  • the drive can be equipped in the same manner as in the gripping pliers 2 according to FIGS. 1 to 3 with the difference that in the embodiment according to FIGS. 4 and 5, the gripping eccentrics 31, 32 and 33 on the outer circumference of the Forging blank 33 act non-positively, so that it can be gripped by the conveyor 1, lifted and pivoted on the trajectory Y and placed in the motor-driven lower die 5 without braking the same.
  • the outer diameter of the forging blank 33 is checked at the same time.
  • the forging blank 33 is eliminated. If the tolerances are met, the forging blank 33 is placed in the rotating lower die 5. As in the previously described embodiment, this is done by correspondingly pressurizing the Gripping cylinder 7 and moving the actuating rod 9 in the direction A or B.
  • the unloading device 15 (FIGS. 8 and 9) has a gripper tongs 18 which is designed and driven in the same way as the gripper tongs according to FIGS. 6 and 7 with the difference that the gripping eccentrics 34, 35 and 36 according to FIGS. 10 and 11 are driven synchronously via a toothed rack 37, which is coupled to the actuating rod 9 and this in turn is coupled to the piston rod 8 of the gripping cylinder 7.
  • a pinion 38 meshes with the rack 37, with which two further pinions 39 and 40 mesh.
  • the pinions 38, 39 and 40 are fastened to axes of rotation arranged parallel to one another and are each assigned to one of the gripping eccentrics 34, 35 and 36.
  • the gripping cylinders 34, 35 and 36 have eccentric levers 41, 42 and 43 which engage under the edge 44 of the forging blank 33, so that after lifting out of the lower die 5 with the pivoting of the eccentric levers 41, 42 and 43 under the edge 44 and lifted up on the trajectory Z (Fig. 1) pivoted to the conveyor 17 and stored there.
