- Q-Q is the longitudinal plane of symmetry of the device.
- U-U is the vertical plane of symmetry of the device.
- the four-die forging device for forging presses contains the holder 1 of the upper striker, the holder 2 of the lower striker, holders 3, 4 side strikers, strikers 5-8, distributing guides 9-16 (Fig. 1, 2).
- the holder 2 of the lower striker has space for its rigid attachment to the bottom plate of a press (not shown) by means of grooves 17, 18, for example, like a dovetail, or with the help of special clamps.
- the holder 1 of the upper striker may also have attachment points 19, 20 for rigid attachment to the upper plate mounted on the movable crossbar of the press.
- Both holders 1, 2 of the strikers are rigidly attached to the press in the case when to move up the holder 1 of the upper striker a movable traverse of the press (not shown) is used. In those cases when springs 21 are used to lift the holder 1 of the upper striker, there is no fastening of the holder of the upper striker to the movable traverse of the press (Fig. 31).
- Holders 3, 4 side dies 5, 7 are inclined planes 22-25, corresponding to inclined planes 26-29 of the holders 1, 2 of the upper striker 6 and the lower striker 8 and kinematically connected with them by means of parting guides 9-16 or 42-45, providing recurrent side strikers (Fig. 1-11, 15-21).
- parting guides 9-16 or 42-45 On inclined planes 22-29 of the holders 1-4 of the dies, anti-friction plates 30-37 are installed, reducing friction between the holders of the dies in the process of their mutual movement.
- FIG. 1, 2 shows the option when eight distributing guides 9-16 are mounted on the side surfaces of the holders 1, 2 of the upper and lower heads.
- the distributing guides on the side surfaces of the holders 1, 2 of the heads is achieved by the most smooth movement of the latter, without jamming and distortions.
- the operation of the device can also be ensured by using four distributing guides 10, 11, 14, 15 installed on the side surfaces of the holder 1 of the upper striker (Fig. 3, 4). In this case, when lifting the holder 1 of the upper striker upwards, the holders 3, 4 of the side strikers lower under the action of gravity down four guide rails 10, 11, 14, 15.
- the first, known, variant of fastening of the distributing guides 9-16 is that they are fixed fixedly on the holder 1 of the upper striker and the holder 2 of the lower striker, and the internal plane of the distributing guide is movably in contact with the plane covered by it, made on the holder 3 or the holder 4 lateral strikers, or with a part plane rigidly mounted on a side striker holder, for example, with the plane of the anti-friction plate 33, 41 (Fig. 1, 6-8).
- fastening of the parting rails provides the required high level of the device assembly and the maximum overhaul period of its service.
- the second mounting option razvoditelnyh guides, which consists in the fact that the distributing guide is fixed on the holder side of the striker, and its inner plane is movably in contact with the covered plane, made on the holder of the upper or lower striker, or with the plane of the part rigidly fixed to the holder of the upper and lower striker, for example, with the plane of the anti-friction plate (not shown).
- centering guides 38, 39 can be located, which fit into grooves of rectangular cross section in holders 3, 4 (Fig. 6-8, 12). Using the centering guides 38, 39, the lateral displacements of the holders 1-4 are reduced and higher forging accuracy is achieved.
- the grooves of a rectangular cross section, in the plane of transverse symmetry of the device, into which the centering guides go, can be formed by anti-friction plates 33, 41 of rectangular section or U-shaped cross section (Fig. 6-8).
- the anti-friction plates 33, 41 of the U-shaped cross-section which are in contact with the anti-friction plates 32, 40, with their own sides, can form a groove of a rectangular cross-section, into which the centering guides 38, 39 fit, and the other THER ⁇ industrial melt cover the side planes of the holders 3 4.
- the inner planes of the distributing guides 9-16 cover the anti-friction plates 33, 34, providing a movable contact with them when lifting the holder 1. This design is simpler in manufacturing and assembly.
- Distributing guides 42-45 can also be made in the form of an I-beam (Fig. 13-21). They are installed on inclined planes of the holders of the strikers, in the longitudinal plane of symmetry of the QQ device. There are several options for installing spreader 42-45, made in the form of an I-beam, on inclined planes of the holders of the strikers, in the longitudinal plane of symmetry of the QQ device (Fig. 13-21).
- the first, well-known variant of the installation of the distributing guides is that all four distributing guides 42-45 are fixed on the holders 3, 4, and the inner plane of each divider guide movably contacts the inner plane of the holders 1, 2 covered by it (Fig. 15) . This option provides reliable fastening of the parting guides and their long work without breakages.
- the diverting guides which consists in that all four distributing guides 42-45 are fixed on the holders 3, 4 side dies of the antifriction plates 33 (34) and 30 (37), and the inner plane of each divider guide is in movable contact with the covered the plane of the anti-friction plate 32 (35) and 31 (36), rigidly mounted on the upper holder 1 and the lower holder 2 of the strikers (Fig. 17).
- This option is much easier to manufacture the previous ones, since it does not require the manufacture of complex T-shaped grooves in holders 3, 4 side dies, as well as holders 1, 2 upper and lower dies.
- the diverting guides which consists in that all four distributing guides 42-45 are fixed on the holder 1 of the upper striker and holder 2 of the lower striker, and the inner plane of each guide movably contacts the internal plane of the side striker 3 and holder 4 covered by it. side punch (not shown).
- This option provides reliable fastening of the parting guides and their long work without breakages.
- This The option of installing guides may not be carried out in all cases, since it requires the manufacture of complex T-slots in all holders of the strikers.
- distributing guides 10, 11, 14, 15, 44, 45 which consists in the fact that on the side surfaces of the holder 1 of the upper striker (or holders 3, 4 side strikers) the distributing guides 10, 11, 14, 15 are fixed , and on inclined surfaces of the holder 2 of the lower striker (or holders 3, 4 side strikers), in the longitudinal plane of symmetry of the QQ device, the distributing guides 44, 45 are fixed (Fig. 22, 23).
- This option can be used in the case when it is simpler in the performance of other options and distributing guides do not fit the installation of other equipment on this device.
- distributing guides 9, 12, 13, 16, 42, 43 which consists in the fact that on the side surfaces of the holder 2 of the lower striker (or holders 3, 4 of the side dies) fixed distributing guides 9, 12, 13, 16 , and on inclined planes of the holder 1 of the upper striker (or holders 3, 4 side strikers), the distributing guides 42, 43 are fixed (Fig. 24, 25).
- This option can be used in cases when, for any constructive or technological reasons, it is necessary to free up space on the side surfaces of the holder of the upper striker or holders of the side heads.
- An anti-friction coating 46 can be applied on the inner planes of the distributing guides 9-16, 42-45, which provide the movable contact in the locking connection (Fig. 6-11, 15-21, 23, 25). This significantly reduces the friction between the contacting planes, eliminates the appearance of scoring on these planes and allows you to increase the turnaround time of service ram distributors.
- a bronze coating can be used, for example, BrAZHMts 10-3-1.5,
- Holders 3, 4 side dies 5, 7 chetyrehvalkovochny forging devices in longitudinal section have a shape close to the shape of a truncated pyramid (Fig. 1, 26, 27).
- the center of mass 47 of each system “side-dies holder – side dies” does not extend beyond the limits of the longitudinal section of the holder 3 of the side dies 5 (Fig. 26, 27). This ensures a smooth, without distortions, movement of the system “side-striker holder-side striker” during reciprocating movements of holders 3, 4 side strikers 5, 7 (Fig. 1).
- protrusions 48, 49 In the lower part of the inclined plane 22-25 of each holder 3, 4 of the side striker there are protrusions 48, 49 in which the anti-friction plates 30-37, 40, 41, 50 abut (Figs. 1, 5-8, 28). These protrusions provide a secure antifriction plate. In the absence of such protrusions, it is possible to cut the fastening screws 51 holding the anti-friction plates 33, 50 on the inclined planes of the holders 3, 4 side of the strikers, their slipping from these inclined planes and breaking (Fig. 28).
- each striker in cross section, consists of a central working area 52 and two side sections 53, 54 (Fig. 29, 30).
- the maximum width of the working surface of the striker (b max ) and the length of the sliding surface of the antifriction plate (1) are related by the relation:
- the width of the central working section of the striker (L c ) and the length of the striker (L) can be related by the relation:
- This ratio ensures maximum performance of the forging process in the inventive device and, at the same time, the high quality of forgings.
- the holder 2 of the lower striker may have a T-shape in cross section with a wide part 55 on the side of its supporting surface (Fig. 2, 4). This is done for convenience during operation of the device and its maintenance during repairs.
- Such the design provides greater stability of the forging device during operation and allows you to securely and firmly fasten it to the wide support surface 55 to the bottom plate of the press (not shown) with the help of grooves 17.18, for example of the “dovetail” type.
- the holder 1 of the upper striker may also have a T-shaped cross section with a wide part 56 on the side of its supporting surface (Fig. 2, 4). This allows you to evenly transfer the load on the forging unit during pressure on it from the upper movable cross head of the press (not shown), and also securely and rigidly secure the forging device for its wide support surface 56 to the upper movable press plate using, for example, special grooves and clamps 19, 20.
- the four-piece forging device can be additionally equipped with at least two centering guide columns 57, installed in the lower striker holder 2, symmetrically relative to the vertical UU and longitudinal QQ planes of its symmetry, with the possibility of vertical movement in these guide-columns 57 of the upper holder 1 striker, which is made spring-loaded spring 21 relative to the holder 2 of the lower striker (Fig. 31).
- a pair of distributing guides 9-16, located on the side surfaces of the holders 1-4 of the dies, symmetrically with respect to the longitudinal plane of symmetry of the QQ device, can be fixed in pairs on the lateral surfaces of the upper holder 1 and the lower holder 2 of the dies with pins, studs or bolts 58 extending through these holders of the strikers parallel to the vertical plane of symmetry of the UU device (Fig. 2, 4, 6-11).
- Distributing guides 9-16 located on the side surfaces of the holders 1-4 of the dies can be fixed with pins, studs or bolts 59 located in a plane perpendicular to the vertical plane of symmetry of the UU device (Fig. 32). This fastening of the guide rails 9-16 in some cases may be easier to perform than the fastening of the cable guides shown in FIG. 2
- the strikers 5-8 of the four-die-casting forging device on the holders 1-4 can be fixed with the help of pins, studs or bolts 60 passing through these holders of the strikers parallel to the vertical plane of symmetry U-U, and clamps 61 (Fig. 1, 33). This ensures reliable fastening of the strikers 1-4 even when they are heated to high temperatures during operation,
- the four-die forging device can be equipped with a lubricant supply system to the rubbing surfaces, while the central channels 62 supplying lubricant to the device pass through the holders 3, 4 side dies, parallel to the slip planes of the anti-friction plates 30-37 (Fig. 1, 5, 28, 34) . This achieves effective lubrication of the rubbing surfaces of the device.
- Antifriction plates 31, 32, 35, 36, mounted on holders 1, 2 of the upper and lower heads can be made of bronze, and antifriction plates 30, 33, 34, 37, mounted on holders 3, 4 of the side heads - of steel ( Fig. 1).
- bronze can be used, for example, brand Bramts 10-3-1,5, and as steel, for example, brand XI 2M.
- Anti-friction plates 30-37 or 40, 41 can also be made of a composite material containing high-temperature polyamide and long-fiber carbon with the addition of graphite filler used for the manufacture of self-lubricating sliding bearings (Fig. 1, 6-8).
- a composite material containing high-temperature polyamide and long-fiber carbon with the addition of graphite filler used for the manufacture of self-lubricating sliding bearings (Fig. 1, 6-8).
- graphite filler used for the manufacture of self-lubricating sliding bearings (Fig. 1, 6-8).
- composite material "Vercomp 200". The use of this material provides a low coefficient of friction (0.18-0.25), high compressive strength
- Four-die forging device operates as follows.
- the forging device is installed in the working area of the forging press.
- the holder 2 of the lower striker 8 is rigidly fixed on the lower plate of the press (not shown) (Fig. 35).
- the holder 1 of the upper striker 6 can also be rigidly fixed to the upper plate mounted on the movable traverse of the press. In some cases, the holder 1 is not fixed on the upper plate of the press, if springs are provided in the forging device for lifting it (FIG. 31).
- the four-die forging device is opened to the required size due to the upward movement of the holder 1 of the upper striker by means of a movable traverse of the press (or springs).
- the manipulator serves the workpiece in the workspace. Then include the working stroke of the press, in which its sub-traverse traverse moves down the holder 1 together with the upper die 6 in the direction to the workpiece 64.
- the upper die holder 1 through the inclined planes acts on the inclined planes of the holders 3, 4 side dies, which due to this move together with the side dies 5, 7 in the radial directions and to the lower dummy 8 and begin to simultaneously compress the workpiece 64 (Fig.
- the operation of the four-die-casting forging device with distributing guides located on inclined planes of the holders of the strikers is similar to the operation of the device with the diverting guides located on the side surfaces of the holders of the strikers.
- the holders of the side dies in the longitudinal section had a shape close to the shape of a truncated pyramid with the center of mass of the system “side dies - side dies” system, not going beyond the limits of the longitudinal section of the side dies.
- the relationships were maintained:
