Definitions

  • the invention relates to a machine casing, in particular for a printing unit of a printing press, which in addition to the protective function also fulfills a sealing function for machine elements supplied with lubricant.
  • a machine cover of this type is known from DE-G 8 620 168.9. Clamping angles are arranged in the edge area, between which there is an elastic profile rubber. This solution is very complex and requires many individual parts.
  • EP 0 417 465 A2 Another protective device for printing presses is known from EP 0 417 465 A2, in which the protective device encapsulates the printing units and consists of a sound-reducing material. If the protective device is made in several parts, sealing elements are used. A sealing function for lubricants cannot be found.
  • the object of the invention is to develop a machine cover that can be produced with little effort, consists of a reduced number of parts and fulfills a reliable sealing function against lubricants.
  • the machine cladding made of sheet metal consists of at least one component with at least one side wall that is plane-parallel a flange is assigned.
  • a circumferential depression is made in the side wall or the flanged wall, in which a rubber is preferably arranged as the circumferential sealing material.
  • the sealing material is elastic and resistant to lubricants.
  • a cover is attached to the machine casing, which can also be designed as a door.
  • the machine cladding reduces the manufacturing costs and, in addition to the protective function, also improves the sealing function of free spaces for accommodating machine elements that are supplied with lubricant. The reduction in manufacturing costs results in particular from the complete elimination of subsequent (after the bending processes) non-cutting or machining steps.
  • the machine casing can be coated with a sound-absorbing, lubricant-resistant material.
  • a plate 1 is in the form of a sheet metal blank for a flat preform as the starting material for a machine cladding in FIG. 1 shown.
  • the circuit board 1 has already been provided with all the necessary openings, for example in the form of notches 15, bores 16 or openings 17.
  • the processing can be carried out, for example, by punching, using a laser beam or cutting tools (drills, milling cutters, etc.), which will not be discussed further.
  • the circuit board 1 is processed in the method steps described below to form a component of a machine cladding which has a side wall 13, a flanged wall 14 and a circumferential depression 10 on at least one side, in which a sealing element 9, preferably an elastic circumferential rubber, is arranged.
  • the openings 15 to 18 provided in the side wall 13 and the flange wall 14 are congruent one above the other, so that the machine casing or the component can be connected to an associated side frame 22.
  • the manufacturing process takes place as follows: A tool known per se in forming technology, especially in sheet metal forming, is used for the angular bending of blank 1.
  • the tool essentially consists of a punch 3 and an associated die 4.
  • the punch 3 is fastened to a punch holder 2 and the die 4 has a bending die with a die profile 5 in a U-shape, which is directed in the direction of the punch 3 changes into a V-shape.
  • the die 4 is assigned a movable stop 6 (FIGS. 2, 6, 9, 11) and at least one side surface of the die 4 is designed as a stop 7 (FIG. 7).
  • the punch holder 2 has a surface 30 which is arranged plane-parallel to the surface of the die 4.
  • the circuit board 1 is positioned against the stop 6 in such a way that the stamp 3 is above a bending line 12 of the circuit board 1 (FIG. 2).
  • the stamp 3 penetrates with the circuit board 1 into the die 4, an angle is bent so that the flange wall 14 is formed (FIG. 3).
  • the punch 3 is moved back out of the die 4 and moved vertically parallel to the exposed side face of the die 4, such that a face 30 of the punch holder 2 bends the flanging wall 14 along the bending line 12 plane-parallel to the plate 1 (FIGS. 4, 5).
  • the stamp 3 also serves as Attack.
  • the openings in the form of notches 15, bores 16 or elongated holes 18 are thus congruent.
  • the board 1 resting on the die 4 is moved further against the stop 6 to the position of the intended depression 10.
  • the punch 3 is moved towards the board 1 and bends the depression 10 at an angle which depends on the thickness of the board 1 and is the die shape (Fig. 6).
  • the board 1 is rotated in the tool and on the back the side wall 13 is angled away from the board 1 along the bending line 11 (FIG. 1).
  • One side surface of the die 4 is used as a stop 7 (FIGS. 7, 8).
  • the first side of the circuit board 1 is thus produced.
  • the opposite side of the circuit board 1 is moved according to FIG. 9 against the stop 6 and in the present example the punch 3 bends the stiffening wall 24 at a right angle (FIG. 10).
  • the side wall 13 is bent at right angles to the circuit board 1.
  • the second side of the board 1 is finished (Fig. 13).
  • the circuit board 1 is now angled at the bending lines 19 and 20 and the finished component can be connected to adjacent components 27, 28 and 29 as a cladding 8.
  • the second side of the circuit board 1 can, however, also be formed after the above-mentioned method steps of the first side, namely with a side wall 13 and a flanged wall 14 and a depression 10 for receiving a sealing element 9.
  • the entire machine casing can be made from a single board 1.
  • the sealing element 9 is glued circumferentially into the depression 10, and the sealing element 9 can also be clamped between the side wall 13 and the flange wall 14.
  • the machine cover, enclosing the free space 23, is fastened to a side frame 22 by means of detachable connecting elements 21.
  • the sealing element 9 is thus arranged between the side frame 22 and the machine cladding or the circuit board 1 and completely seals the surroundings against lubricant occurring in the free space 23.
  • the drive elements that require lubrication are generally arranged in the free space 23.
  • the Machine cover arranged approximately parallel to the side frame 22, a cover 26 in which a sealing element 25 is incorporated.
  • the cover 26 is connected to the machine casing or the circuit board 1 via connecting elements 21.
  • the cover 26 can also be designed as a door with hinges and connecting elements.
