The device comprises a bed 1 of the preforming section 2 of a glass forming machine. With the aid of section 2, the portions of the drip feeder (not shown) of the liquid or viscous glass portions are molded by pressing and blowing into hollow glass objects.
With the bed of the machine 3, the section 2 is firmly connected vertically to the stand of the hinge 4, on which the half 5 and 6 of the preformed pincers are rotatably mounted. The hinge pillar 4 has an axis 7. At half 6 of the preforming tongs, the reverse lever 8 is strengthened, which is connected with the bolt 9 to the bar 10. Similarly from the half of the five preforming forceps, the reverse lever 11 is articulated with a finger 12 and the bar 13. Each bar 10 , 13 is connected to the crank pin 14 of the crank mounted on the drive shaft 15. The drive shafts 15, on which the cranks are fastened 16, are simultaneously and oppositely driven by half of the 5 and 6 in the technological cycle preforming forceps between end positions.

In the lateral recess 17 of each half, 5 and 6 spikes of preforming are located on the balance pin 18 with the possibility of swinging.
yoke 19. In each yoke 19 inserted two coupling halves 20 of the molding tool 21, designed as a dual form. The molding tool 21 has, in addition, two divided mouths 22 and 23 which, in a known manner, independently of the halves 5 and 6 of the preforming forceps, are installed with the possibility of turning on the lever 24 of the section 2 around the longitudinal axis 25 of the lever 24. In the closed position of the halves 5 and The 6 preforming forceps the lower zones of the halves of the half-molds 20 of both the halves 5 and 6 of the pre-molding cover the upper zones of the closed mouths 22, 23 and form the closed half-molds.
The work is carried out as follows.
Through the upper bottom hole. 26 of the closed half of the half-mold 20 in a known manner is introduced a set of glass melt and through a bottom-up moving through the mouth 22, 23 of the punch 27 is molded into a jar.
On each half of the 5, 6 preforming, the distribution device 28 of the working environment is strengthened, which has
upward directed outlets 29 for the working fluid, in this case compressed air. Half-molds 20 with an annular surface 30, which
together with the outlet openings 29 has coaxial inlet openings 31 of the channels 32. Each channel 32 of the half-mold 20 lies in a plane passing through the longitudinal axis 33 of the half-mold,
and has a discharge outlet 34 above.
The bed frame 3 has a chambered upper chamber.
air crossmember 35, which for each switchgear of the working medium has a gap 36. In each gap 36 an insert 37 is inserted with a SUPERVISION channel 38 and a gate valve 39. The insert with screws 40 is mounted on the crossbar 35. Each insert 37 bears 41 screws reinforced by 41 that covers the other part of the supply chain
Nala 38 cooling air. A upper mounting bore 43 of the nozzle 42 is inserted a bearing sleeve 44, which encloses the upper part in the form of a circular cylinder of the supply channel 38 with a longitudinal axis 45 parallel to the axis 7,
A drive pin 46 is mounted on each switchgear 28 at a distance from the balancer pin 18. The longitudinal axis of each drive pin 46 defines an axis 47 parallel to the axis 7 and axis 45.
The drive fingers 46 go down out through the lower limitation of the switchgear 28 of the working medium and engage with part of the crankshaft 48. The drive fingers 46 and thereby the axis 47 swing during the opening and closing of the preforming halves 5 and 6 on the arc of a circle around the axis 7. The driving fingers 46 capture in this oscillatory movement of the part of the cranked channel 48, i.e. portions of the crankshaft 48 move in a plane of movement perpendicular to the axes 7, 45, 47.
Each part of the cranked channel 48 moves in the plane of movement by slotting crackers 49 and 50 relative to the supply channel 38. The slotting crackers 49, 50 are fastened with screws 51 on another part of the cranked channel 52, which is rotatably mounted around the axis 45. Dp of this other part of the crankcase the channel 52 has a downwardly extending bearing ring 53, which surrounds the connecting channel 54 permanently connected to the inlet channel 38. The lower outer flange 55 is held in an additional annular groove of the bearing sleeve and 44 half-rings 56 and 57 divided by a length of retaining ring 58. I.
The location is chosen so that when
the oscillatory movement of the halves of the p; pre-molding units 5, 6 of the part of the cranked channel 48, on the one hand, are oscillatingly gripped around the axes 47 by means of the driving fingers 46, and on the other hand, they are directed through the slot crackers 49, 50, which each part of the cranked channel 48 constantly intersects the axis 45. Parts of the crankshaft 3054
The helix 48, thus, performs a combined oscillatory movement and a movement of movement in the said plane of movement.
The axis 47 moves between the fully closed and fully open position of half of the 6 preforming forceps in an arc of a circle 59 around the axis 7. In addition to the oscillatory
On movement, part of the crank bore 48 performs between the end positions a directional movement of the slot crackers 49, 50, a movement of movement in the direction of its longitudinal axis 60. When
5, a portion of the cranked channel 48 with the bottom surface 61 slides along the upper surface 62 of another part of the cranked channel 52. There is a small gap between surfaces 61, 62.
0 The leakage of the working medium through this gap, in particular with a relatively small pressure to blow the working fluid, is too insignificant.
5 The outlet 63 of the parts of the crankshaft 48 is an almost complete annular shape. The annular shape is interrupted only by a radial crosspiece: 64, which
connects the wall of the housing part 65
a crankshaft 48 with a hollow cylinder 66 of a part of the crankshaft 48, concentric to axis 47. An axle bushing 67 is inserted into the upper end of the hollow cylinder 66 to receive the lower end of the drive pin 46. The outlet 63 is bounded outside by an angled ring 69 that is inserted from the outside.
On each nozzle 42 there is a connecting nipple 70 for supplying compressed compressed air. Compressed air is supplied to the cylinder 71 through a system of channels in the
 cage 42 and actuates the piston 73 connected to the eubchatuy rake 72. The gear 74 on the shaft 75 of the vertical flap 39 is engaged with the toothed rack 72, Ta-
In a QIM way, the valve flap is remotely installed between the position completely closing the supply channel 38 and the position fully opening the supply channel 38,
The cooling air flow path is shown in FIG. 3 elongated arrows, and the direction of movement - contour arrows. Coolant
the spirit passes from the connecting channel 54 through the inlet 76 in the bottom surface 61 of the part of the cranked channel 48, which is extended in the direction of the axis 47, into the internal cavity 77 of the part of the cranked channel 48 and from there to the outlet 63,
The dispenser 28 of the worker has an annular inlet 78, concentric to the axis 47, which captures cooling air from the outlet 63. The inlet 78 is bounded by a tubular extension that, when mounted with the lower annular end surface, is located on the upper adjacent surface of the corner ring 69 crankshaft 48 and together with it forms a sliding seal. The compression spring 79 pushes the tubular extension 80 down into the seal contact with the corner ring 69. The cooling air flows from the inlet 78 in the direction of the continuous arrows through the system of working environment switchgear 28 until it comes up through the outlets 29 and enters the channels 32 half half molds 20.
The tubular extension 80 is axially directed with the ability to move with a tapered upper part in the mounting bore 81 of the distribution device 28 of the working medium. It has lintels radially inward. If the length of the halves of the half-molds 20 is changed when changing the hollowed glass items to be manufactured, the layout of the cooling device from the insert 37 to the part of the bend channel 48 remains completely unchanged. Alignment in height to the new length of the halves of the half-molds 20 is carried out by replacing the tubular extension 80 with an analogous extension that is suitable in length.
Half rings 56, 57, bearing sleeve 44 and nozzle 42 are fixed against each other in the axial direction with screws 82 offset by 45 °. The fit between the half-rings 56, 57 and the bearing sleeve 44 is so relative to the lower outer flange 55 of the bearing ring 53 that between these parts

There is a relatively large gap, which allows free relative oscillation of the bearing ring 53 around the axis 45. This gap results in only small leaks from the working medium.
The bottom surface 61 of the part of the crank bore 48 is determined by the plates 83 and 84, which are fixed to the bottom side 85 of the crank bore 48 by screws 86 and 87, and the screws 86 reach the upper side 88 of the crank bore 48.
Each plate 83, 84 is positioned with two positioning pins 89 relative to part of the bend channel 48.
In the zone of movement of the groove crackers 49 and 50, the plates 83, 84 form guide rails 90 and 91, as well as 92 and 93, which engage in the side grooves 94–97 of the slot grooves 49 and 50 for the longitudinal direction of the part of the cranked duct 48 the direction of the longitudinal axis 60,
Slot crackers 49 and 50 have a cross section. The connecting nipple 70 for regulating air supply is shifted by 45. Vent Gate
39 is in its closing inlet channel 38, in which the piston 73, when pre-compressed by the compression spring 98 in its upper final position, leans to the underside of the nozzle 42. If the adjusting compressed air is supplied through the connecting nipple 70 to the cylinder 71, the valve flap 39 pivots under the increasing opening of the supply channel 38.

The section 99 of the finishing forms of the glass-forming machine contains on the hinge rack 100 rotatably arranged two half-pieces 1prints 101 of the finishing form, of which FIG. 9 shows only the top. Each half of the finishing tweezers 101 is articulated with a pin 102 with a strap 103, which is connected to a crank pin 104 of a crank 15 driven by a drive shaft 106 located in the frame of the machine 3. Both drive shafts 106 and hinge stand 100 are interconnected by a cross beam 107 which is located at a distance of 108 from the cross-piece 35 of the frame of the machine 3.

In the lateral recess 109 of each half of the tweezers 101 of the finishing form, the balance arm 111 is rotatably mounted on the balance finger PO fixed to the half of the tweezers 101. Two halves 112 of the final shape are inserted into each rocker arm 111, of which in the upper half of FIG. 9 shows only one. The presented section 2 thus operates in a double mode and in each technological cycle simultaneously produces two hollow glass objects.
On the underside of each rocker arm 111, a working medium dispenser 113, made in a similar way, is strengthened and acts as a dispenser 28 for the working medium of the preforming bed 1. Each working dispenser 113 has a cooling air inlet 114. The finishing form 112 has a longitudinal axis 115. The exit from the inlet 114, the cooling air is divided inside each switchgear 113 of the working medium into separate jets and comes out of the slots 116 of the switchgear 113 of the working medium concentrically bent to the longitudinal axis 115 of half 112 finishing form. From the slots 116, the cooling air enters the upper channels 117, which lie in a plane passing through the longitudinal axis 115, and emerge on the upper side of the halves 112 of the final shape. I
Under the head plate 107 on each side of the hinge pillar 100 in cross member 35 there is a hole defining the inlet channel 38 of the cooling air. A portion of the crank channel 118 forms a permanent connection between each inlet channel 39 and the inlet 114 of the working fluid distributor 113. Thus, the cooling air, irrespective of the position of the swing of the halves of the finishing tweezers 101, can constantly get into the channels 117 of the halves 112 of the finishing. FIG. 9, the upper half shows the fully open position, the lower half shows the fully closed position of the distribution switch
