Definitions

  • the subject of the present invention is a press with a box frame having hydraulic-, mechanical-or other drive, which can be applied for various technological purposes, especially for plastic working.
  • presses with a frame supporting structure being a further progress in the design of previously applied C-frame presses.
  • presses with a frame supporting structure enable a considerable increase of rigidity of the frame and rigid guidance of the press slide, which in C-frame presses was supported from two sides, whereas in presses with a frame supporting structure - from four sides.
  • a substantial disadvantage of the known frame structures was the necessity of applying correspondingly big assembling windows enabling introduction of the slide and the driving mechanism to the inside of the press frame, as well as difficulties associated with the treatment of surfaces for guides of the inner part of the press frame.
  • presses with a frame design are most often equipped with guides of the press slide situated in its corners due to which the contact surface of slide guides is considerably limited.
  • roll - lateral guides have been applied, which, however, for the reason of the quantity of transferred pressures, have not given positive results because of a too small contact surface of guiding elements.
  • a particular inconvenience has been shown by presses with a frame supporting structure at the application of hydraulic drives. Namely for the reason of assembling difficulties the hydraulic drive is mounted outside the press frame, most often on its top, and is attached to the said frame by means of screws, the said screws transferring forces coming from the main pressure of the press.
  • the frame consists of a box open at one side and a flat closing plate connected thereto, whereby the driving mechanism can be situated both in the box and in the closing plate.
  • Presses of this type are characterized by increased rigidity and an easy access to the working space of the press, however, in result of the fact that the parting planes of elements of the supporting unit of the press are perpendicular to the working direction of the press slide the connecting elements, usually screws, transfer forces resulting from the working pressure of the press. Transfer of pressure forces occurs in all parting planes of both the frame and the drive of the frame.
  • this task is solved by creating a press with a box frame provided with holes enabling an access to the working space of the press and a press slide guided inside said box frame, characterized in that said box frame is formed by two similar parts being symmetrical to a parting plane parallel to the direction of the working motion of said press slide. Due to this elements connecting both parts of the frame do not transfer forces originating from the main pressure of the press. Besides, the design of this type enables an access to the interior of the frame in a dismounted state in order to perform a treatment of surfaces and to fix guides of the press slide.
  • fig. 1 presents the press with a split frame in a perspective projection
  • fig. 2 presents the same press in a schematic vertical section with a plane CC
  • fig. 3 - one of the two parts of these frames of the presses in the view from the centre
  • the frame of the press consists of two similar parts 1 and 2 being symmetrical to a parting plane 3 and forming after connection a closed box (fig. 1) provided with holes 4, 5 enabling an access to the working space of the press, the parting plane 3 of both parts 1 and 2 being parallel to the direction 6 of the working motion of the press slide 7.
  • both parts 1 and 2 are provided with grooves 8 in which slats 9 protecting against mutual displacement of both parts 1 and 2 in the parting plane 3 are situated.
  • flat guides 10 are fixed which serve for guiding the slide 7 of the press, whereby as opposed to the hitherto known designs the slide is guided along side surfaces and not on corners.
  • the slide 7 is connected with a plate 11 serving for fixing tools and provided with a discharging hole 12 serving for discharge of ready details and wastes from the inside of the press.
  • a plate 13 is fixed to parts 1 and 2, serving for fixing the upper part of a tool.
  • a guide 70a of the slide 7 covering the parting plane 3 of both parts 1 and 2 of the frame and the upper tool plate 13 are at the same time elements connecting both parts 1 and 2 of the press frame, whereby the said elements do not transfer forces coming from the main pressure.
  • the slide 7 is provided in corners with bevels 14 enabling a correspbnding thickening of corners 15 of parts 1 and 2 of the press frame, and due to this, correspondingly, an increase of rigidity of the said frame and advantageous transfer of loads acting on the said frame.
  • the press according to the invention is mounted so that to part 1 of the guides 10 and 70a of the slide 7 are fixed, and then the tool plate 13, and in part 1 the slide 7 is mounted together with the press drive which is not shown, and then the frame together with the mounted slide and the drive is closed by the other part 2 of the frame fixed by means of pins and screws situated in guides 10 and the plate 13.
  • the press according to the invention can be applied both as a press with hydraulic drive, mechanical drive and other.
