Definitions

  • the invention relates to a four-jaw forging device with a holder for an upper jaw and a holder for a lower jaw, wherein the holders provided with inclined surfaces and kinematically connected with holders for side jaws and only corresponding oblique surfaces as the holders for the upper and bottom jaw are provided, wherein on the inclined surfaces of the holders for the upper, the lower and the side jaws slide plates are arranged, wherein eight lateral connection guides a kinematic connection between the holders for the upper and the lower jaw with the holders for the side jaws wherein four jaws with working and bearing surfaces are incorporated in the jaw holders and wherein a system for supplying lubricant to the friction pairs of sliding plates is provided.
  • the apparatus may be used in mechanical and metallurgical industries for the manufacture of products having an elongated axis such as suction, supports, interstitial cells, torsion shafts, rolls and similar products, as well as for the production of forgings for further forming, e.g. Forging blocks made of structural, stainless steel, heat-resistant and difficult to deform steels and alloys are used.
  • a four-jaw forging apparatus which consists of two holders with inclined surfaces for the upper and the lower jaw. These brackets are kinematically connected to the holders for side jaws (with sloping surfaces). The surfaces correspond to the oblique surfaces of the upper and lower holder. They are arranged at an angle of 3 - 75 ° with respect to the vertical central longitudinal axis of the device. The device is also still with the four jaws, which are mounted in the corresponding jaw holders.
  • This device makes it possible to produce forging blocks of high quality with low Einschmiedungshack. It allows the forging of billets, which have a wide cross-sectional area.
  • This design of a four-jaw forging ensures a longer life.
  • the disadvantage of this known four-jaw forging device is that it does not ensure a sufficiently long service life without repair, as formed on the working surfaces of the sliding plates so-called “eaters” that prevent sliding.
  • centering guides 14 and 15 are provided in the inclined surfaces of the holder 1, 3 and 16, 17 for the upper and lower jaw 7, 9 and 21, 23 and in the inclined surfaces of the holders 5, 6 and 18, 19 for the lateral jaws 8, 10 and 22, 24 are installed in one or more planes, wherein the planes of the central guides 14 and 15 perpendicular to the longitudinal center plane 0-0 of the device run that the width B 1 of the working surface of each jaw 7 - 10 and 20 - 24 is 0.5 - 0.0 of the width B 2 of the bearing surface of the jaws 7 - 10 and 20 - 24 and that the entire contact surface S 1 of the slide plates 12 and 20 on the inclined surfaces of the holders 5, 6 and 18, 19 for the side jaws 8, 10 and 22, 24 and with the sliding plates on the holders 1, 3 and 16, 17 for the upper and lower jaw 7, 9 and 21, 23 in the closed device to the total area S 2 of the Schwarzi on the working surfaces of the lateral jaws 8, 10 and 22, 24 on the longitudinal center axis 0-0 the device is determined
  • centering guides which are installed on the inclined surfaces of the lateral holder in one or more levels. These planes are perpendicular to the longitudinal central axis of the device.
  • the planes are formed by centering grooves, wherein the centering grooves are formed by the walls of the grooves, which on the inclined surfaces of the holders for the side jaws or holder for the upper and lower jaw are executed. At the same time, these centering grooves are formed by lateral surfaces of the sliding plates.
  • the lateral connection guides have an F-shaped cross-section. The width of the working surface of each jaw is 0.5-0.9 of the jaw of the bearing surface of these jaws.
  • the entire contact surface S 1 of the sliding plates provided on the inclined surfaces of the holder door of the side jaws, with the sliding surfaces mounted on the holders for the upper and lower jaws in the closed device and the total area S 2 of the projection of Working surfaces of the lateral jaws on the longitudinal center plane of the device is selected in a ratio S 1 / S 2 ⁇ 2.5.
  • the side jaw holders 5, 6 are centered by the centering guides 14 with respect to the upper jaw holders 1, 3 and the lower jaw. Therefore, one or more centering guides 14 can each be arranged on the inclined surfaces of the jaw holders.
  • a centering guide 14 shows Fig. 2 and two centering guides Fig. 3 ,
  • the centering guides 14 can be mounted on the inclined surfaces of the side-jaw holders 5, 6 in one or more planes. These planes are perpendicular to the longitudinal center plane 0-0 of the device.
  • the centering guides 14 can also engage in centering grooves.
  • the centering grooves are placed on the inclined surfaces of the holders 1, 3 for the upper jaw and the lower jaw.
  • the centering grooves are formed by the lateral surfaces of the sliding plates 12 and groove walls ( Fig. 1 to 3 ).
  • centering guides 15 can also be introduced on the inclined surfaces of the holders 16, 17 for the upper jaw and the lower jaw and engage in centering grooves.
  • the centering guides 15 are placed on the inclined surfaces of the holders 18, 19 for the lateral jaws and formed by the lateral surfaces of the sliding plates 20 and groove walls.
  • the lateral connection guides 11 have an F-shaped cross-section. They are firmly attached to the holder 1, 3 for the upper jaw and the lower jaw by means of pins.
  • the connecting guides 11 have a margin to the holders 5, 6 for the lateral jaws on the sliding surface on ( Fig. 1 and 4 ).
  • the jaws 21-24 of the forging apparatus have a shape in cross-section which in FIG Fig. 6 is shown.
  • the attachment of the four-jaw forging apparatus to the press table and the movable press truss is carried out as well as in the conventional jaws.
  • the four-jaw forging works as follows:
  • the working space of the forging device is opened by the movement of the movable Traverse up to the required distance. Thereafter, the billet 25 by means of a manipulator (not shown in the figures) is conveyed into the working space and with the jaws 7 - 10 and 21 - 24 compressed by the movable press truss is guided downwards ( Fig. 7 ).
  • a manipulator not shown in the figures
  • the transmission of the pressing force on the holders 5, 6 for the lateral jaws takes place via the oblique surfaces of the holders 1, 3 or 16, 17 for the upper and the lower jaws, namely during the movement of the holders 5, 6 and 18, respectively. 19 of the side jaws.
  • the pressure on the sliding surfaces of the slide plates 12 and 20 increases rapidly.
  • the billet 25 is fed to a specific value before each swaging from one of the sides of the forging apparatus. This always ensures the eccentricity of the load application with respect to the plane of symmetry of the device. This eccentricity tends to offset the jaw brackets against each other (skew). Due to the inclinations increase the specific pressures that are exerted on individual areas of the slide plates 12 and 20 respectively. This can cause eaters on the surfaces of the slide plates 12 and 20, respectively.
  • the reduction of the inclinations in the forging device to be patented is also achieved by means of the centering guides 14 and 15, respectively.
  • the centering guides are arranged on the inclined surfaces of the one jaw holders and engage in the centering grooves of the other jaw holders.
  • the centering guides 14 and 15 the inclinations between the jaw holders are substantially reduced.
  • the side connecting guides 11 have an F-shaped cross-section. This section of the lateral connecting guides 11 ensures a firmer kinematic connection of the holders 5, 6 and 18, 19 for the lateral jaws with the holders 1, 3 and 16, 17 for the upper and lower jaw.
  • This cross section also reduces the inclinations between the sliding plates 12 and 20 in the friction pairings and, accordingly, the possible formation of scores on the sliding surfaces of the sliding plates 12 and 20, respectively.
