Definitions
- the invention relates to the field of metal forming, in particular to four-sided forging devices and can be used for forging ingots and billets of various steels and alloys on hydraulic forging presses.
- the invention can be used in the engineering and metallurgical industries in the manufacture of products with an elongated axis, for example, rods, columns, intermediate shafts, torsion shafts, rolls of rolling mills and the like, as well as in the production of forged billets from ingots and rolled from carbon, medium alloyed, tool and high alloy steels and alloys, as well as non-ferrous metals and alloys.
- the four-side forging device is known from the prior art, consisting of two holders of the upper and lower strikers with inclined surfaces, kinematically, with the help of guides - links associated with them of two holders side strikers with inclined surfaces corresponding to the inclined surfaces of the upper and lower holders and four strikers attached to the respective holders (1).
- a four-sided forging device comprising two holders of the upper and lower strikers with inclined planes, two holders of the side strikers with inclined planes corresponding to the inclined planes of the holders of the upper and lower strikers, kinematically connected with the said holders of the upper and lower strikers using eight lateral guide rails , centering guides with the ability to center the holders of the strikers, anti-friction plates mounted on the inclined planes of the holder her fights and four fights (2).
- a disadvantage of the known forging device is that its design does not provide high productivity in the process of manufacturing workpieces or products, the production of which requires a quick change of the tool with the withdrawal of the four-flange forging device from the forging zone, and, if necessary, its subsequent return to the working area of the press.
- This is due to the fact that the device requires rigid fastening of the holder of the upper striker to the moving part of the press (upper traverse or upper striker) and rigid mounting of the holder of the lower striker to the press table. To remove the device from the working area of the press, you need to disconnect it from the upper movable part of the press, which takes a lot of time. Also, a lot of time is required to install the device in the working area of the press.
- the basis of the invention is the task, by changing the design of the forging device, to reduce the time to remove the device from the working area of the press and the time to install it in the working area of the press and, due to this, to increase the productivity of the process.
- the task is also achieved by the fact that the device is equipped with a lubricant supply system on the anti-friction plates.
- the task is also achieved by the fact that the device is equipped with a water cooling system for strikers and holders of strikers.
- Patented four-sided forging device is illustrated by drawings (Fig.1-6).
- Figure 1 shows a four-side forging device in a static state, front view (in the closed position - the left side of the figure and in the open position - the right side of the figure); figure 2 is a side view; Fig. 3 is a plan view; in FIG. - section aa in figure 1; Fig. 5 - four-sided forging device in a perspective view; figure 6 - four-side forging device for crimping the workpiece (the cross section of the workpiece is shaded at the time of compression).
- the four-side forging device consists of the holder of the upper striker 1, the holder of the lower striker 2 mounted on the press table (not shown in Fig.), Two holders of the side strikers 3.4, eight side distributing guides 5-8, with the help of which the kinematic connection of the holders is ensured side strikers with holders of the upper and lower strikers, upper striker 9, lower striker 10, side strikers 1 1, 12, four centering guides 13-16 (Figs. 1-5).
- the holders of the upper and lower strikers 1, 2 have inclined planes corresponding to the inclined planes of the holders of the side strikers 3.4.
- springs 27 are installed with the possibility of vertical movement of the holder of the upper striker 1 relative to the holder of the lower striker 2.
- the centering guides 13-16 made in the form of columns, are installed in holes 21, 23, 24, 26 located symmetrically on both sides relative to the longitudinal plane of symmetry of the device “0 - 0“. Moreover, the sections of these guides - columns 13-16 are pressed into the holes 21, 23, 24 and 26 of the holder of the lower striker 2, with the possibility of vertical movement in these guides of the holder of the upper striker 1.
- antifriction plates 28 are installed having a U-shaped cross section (Figs. 1, 4,5).
- the inclined planes of the holders of the side strikers 3, 4 are limited by the rectangular side walls of these holders, covering the antifriction plates 28.
- the lateral guide rails 5-8 are fixedly fixed on the rectangular side walls of the holders of the side strikers 3, 4 so that they cover the side sections of the antifriction plates 28 with the possibility of movable contact on the edge sections of the planes et x antifriction plate on which the inclined plane contact holders lateral pins 3, 4.
- the four-forging device can also be equipped with a lubrication system for anti-friction plates and water cooling system for strikers and strikers holders (not shown in FIG.).
- Four-sided forging device operates as follows.
- the device is installed in the working area of a hydraulic forging press under its upper flat head (not shown in Fig.).
- the holder of the upper striker 1 does not have fasteners on the moving parts of the press.
- the holder of the lower striker 2 is rigidly fixed on the movable table of the press (not shown in Fig.).
- the holder of the upper striker 1 together with the upper striker 9 moves up, and at the same time, with the help of the side distributing guides 5-8, raises the holders of the side strikers 3, 4 together with side strikers 1 1, 12, opening the working space of the device (Fig L, 5).
- the process of breeding strikers 9, 1 1, 12 is as follows.
- the movement of the holders of the side strikers 3, 4 along the antifriction plates 28 upward and to the sides is ensured by the coverage of the side distributing guides of 5-8 antifriction plates having a U-shaped cross section.
- Side distributing guides 5-8 are fixed on the rectangular side walls of the holders of the side strikers 3, 4 with bolts and brought under the edge sections of the antifriction plates 28.
- the workpiece (not shown) is fed into the workspace by a manipulator. Then, the working stroke of the press is switched on, in which its movable crosshead through the upper flat striker (not shown in Fig.) Moves the holder of the upper striker 1 together with the upper striker 9 towards the workpiece. At the same time, the holders of the side strikers 3, 4 together with the side strikers 1 1, 12 also move towards the workpiece. All three movable strikers (9, 1 1, 12) and the lower stationary striker 10 begin to simultaneously compress the workpiece (Fig.6).
- the movable crosshead of the press with the upper flat striker of the press moves up, the holder of the upper striker 1 under the action of the springs 27 also rises up, opening the working space of the device for longitudinal movement and / or rotation of the workpiece around the axis, after which the crimping cycle is repeated.
- To withdraw the device from the working area of the press it is only necessary to raise the upper crosshead of the press, thereby creating a small gap (10-200 mm) between the working surface of the upper flat die of the press and the holder of the upper die, and then remove the entire device from the working area of the press.
- the device can be located on the press tool table near the working area, and at the same time, another tool can be installed in the press working area and continue working on the press using this new tool. If necessary, you can also quickly bring a four-gang forging device into the working area of the press.
- the time to withdraw the device from the working area of the press is 1-3 minutes. The same amount of time is required to install the device in the working area of the press.
- the time for removing the device from the working area of the press is 20-30 minutes, and for its installation - 15-20 minutes.
- the proposed design of the device provides a significant reduction in the time taken to remove the device from the working area of the press and to install it in the working area of the press, thereby increasing the productivity of the process.
