Definitions

  • the invention relates to a forging device consisting of two swaging tool holders arranged between a main and a subframe, movable relative to the underframe perpendicular to the direction of the stroke of the main and articulated by means of articulated levers on the main, and arranged in the swaging zone between the end faces of the swaging tools fastened in these swaging tool holders Press jaws.
  • a forging device in which the press ram is connected by means of articulated levers to the upsetting tools designed as clamping jaws with positive locking, which are movable perpendicular to the direction of the stroke of the press ram.
  • the articulated levers are articulated at one end to a main arranged on the press ram and at the other end to the rear of the upsetting tools.
  • a bending tool and an anvil associated with it are arranged in the compression zone between the end faces of the compression tools.
  • the object of the invention is to provide a forging device which enables the workpiece to be compressed at two points at the same time.
  • this object is achieved in that the press jaws are designed as workpiece holders and the articulated levers which are articulated on the main by means of articulated levers have the form of angle elements, the arms of which are arranged perpendicular to the stroke direction of the main and can be pressed against the jaw of the workpiece holder in the direction of the stroke of the main and at the same time are displaceable perpendicularly to the stroke of the main and the stroke of which Main parallel arms are equipped with upsetting tools.
  • the jaws of the workpiece holder mentioned remain immobile during the entire forming process.
  • adjustable guide members are arranged on the main, to which the articulated levers are articulated. These guide elements serve to regulate the working stroke of the upsetting tools.
  • the arm of the respective angular element arranged perpendicular to the stroke direction of the main is supported by means of a semicircular insert on the jaw of the workpiece holder, this insert being articulated to one of these elements and being displaceably mounted with respect to the other element is.
  • the arm of the respective angle element which is arranged perpendicular to the stroke direction of the main, is supported on the jaw of the workpiece holder by means of a rolling element.
  • the jaws of the workpiece holder can be designed as dies that form the workpiece.
  • a stamp is arranged on the central part of the main, the front part of which can be inserted into an opening in the jaw of the workpiece holder.
  • the forging device according to the invention is to be used to produce two flange-like upsets on rods or tubes at a desired mutual distance, it is recommended that at least one of the upsetting tools be designed as a pair of clamping jaws, one of these jaws being slidably arranged relative to the base frame.
  • the angular elements used in the device according to the invention enable the pressing force directed in the direction of the stroke of the main to be transmitted from the main to the jaws of the workpiece holder, as a result of which the workpiece is clamped in these jaws. At the same time, they also transmit the compression force directed perpendicular to the direction of the main stroke to the two compression tools. No additional mechanisms or servomotors have to be used for these two functions.
  • the device shown in FIGS. 1 and 2 comprises a movable head 1, which is attached to a press ram or another drive, not shown, a central workpiece holder, which is supported on a base frame 11 and has two jaws 2a and 2b, and one these elements connecting compression and clamping mechanism 13th
  • the head 1 has two side arms 1a and 1b, which extend downward in the shape of a fork and are inclined at approximately 45 ° to the vertical.
  • a guide member 3 On each arm 1a and 1b of the main a guide member 3 is mounted in slide bearings, which can be adjusted by means of screws 4.
  • Two bearing rollers 5 are supported on each of these guide members 3.
  • Four articulated levers 6 are articulated to these four bearing rollers 5, which are connected at their other ends to further bearing rollers 5a.
  • These bearing rollers 5a are attached to two angle elements 7.
  • the horizontal arm 7a of each angle element 7 is supported by means of a sliding plate 8 and a semicircular insert 9 on a plate 10 which is arranged on the upper jaw 2a of the workpiece holder.
  • the semicircular insert 9 is rotatably mounted in a recess in the plate 10, which ensures that the cooperating parts fit exactly.
  • the lower jaw 2b of the workpiece holder is attached to the base frame 11.
  • Each angle element 7 is additionally connected to the main 1 by means of a hydraulic cylinder 12, which serves to reset the angle elements 7 and the upsetting tools 13 attached to them.
  • the number 14 is on the drawing indicates the forged workpiece.
  • the guide members 3 on the right and left arms 1a and 1b of the head 1 can be adjusted to different heights so that the right and left angular element associated joint lever are inclined differently and the right and left compression tools various A rbeitshübe have.
  • each of the upsetting tools is designed as a pair of clamping jaws 15a and 15b.
  • the rod-shaped workpiece 16 is clamped between this pair of jaws.
  • the jaw 15a is fastened to the vertical arm 7b of the angle element 7, while the jaw 15b is slidably mounted on the base 11 in a holder 17.
  • the device is mounted in a position rotated by 180 ° in relation to the previous exemplary embodiments.
  • the main 1 rests on a support not indicated in the drawing, for example on the table of a press.
  • the plate 11a is attached to a press ram not indicated in the drawing.
  • a roller 19 is provided instead of the semicircular insert which is shown in FIGS. 1 and 2 as well as 4 and 5.
  • a stamp 20 is arranged in a socket 21 in the central part of the main 1.
  • the jaws 2a and 2b are designed as die halves of a closed die, the engraving of which corresponds to the shape of a cross piece (FIGS. 10 and 11).
  • the parts of the engraving which form two arms of the cross piece lying in one axis, are closed at the outer ends.
  • the other parts of the engraving, in which the two remaining arms of the cross piece are formed, form a channel open on both sides.
  • Central openings are provided in the jaw 2a and the plate 10, through which the stamp 20 can engage in the space of the engraving.
  • the upsetting tools are cylindrical and their diameter corresponds to the diameter of the above-mentioned channel in the jaw 2a or 2b.
  • the workpiece 22 is clamped between the jaws 2a and 2b in the aforementioned channel of the engraving during forging.
  • the upsetting tools 13 press against the ends of the workpiece 22 and cause the material to flow into the entire engraving in the jaws 2a and 2b, in which it is formed.
  • the stamp 20 presses out the central recess 23.
  • a cross piece is formed, which is shown in FIGS. 10 and 11.
