Valps 4 are equipped with automatic mechanisms for 1) narrow and unloading blanks. Further along the axis of the rolls, the usganovt.t. transport is about the movement of the rail to the press 6. Press 6 is installed in such a way that the axis of the conveyor 5 passes through the side windows of the press. The complex 7 of the tooling is installed on the press H in such a way that the extension of the axes of the streams of punches is parallel to the front of the press D).

one axle with a punch 12 for nary hot stamping of the jaws of the levers to the bottom plate 10 of the block 8 are fixedly mounted a photopyrometer 18, servants for the remote control of the press 6.

The stamp 12 for pair hot stamping of the jaws of the levers consists of the upper 19 (Fig. 5) and the lower 20 (Fig. 6) inserts, pins 21 (Fig. 4. 7 and 8) and the stop 22. It serves to fix the rolling 23 relative to a creek of the stamp 12, which are fastened to the lower insert 20. On the upper side of the 9 block 8 are installed with the possibility of entering the grooves of the lower insert 20 (Fig. 4 and 6) spring-loaded clamps 24 (Fig. 5), which serve to prevent the bending of the rolling pens 23 .

The stamp 13 for trimming the scrap (Fig. 3) consists of a cut matrix 25 (Fig. 7 and 9) of the intermediate plate 26, spring-loaded clamps 24 (Fig. 5 and 7) attached to the upper section 9 of the block 8 of the cut punch 27 , pins 21 and skidding 28 for removing the plume (phi1. 8) installed on the bottom plate 10 of the block 8. The bores of the ejectors 29 are installed in the bores of the intermediate plate 26 (phi1. 9) and the cut matrix 25.

The handle profiling mechanism 14 (Fig. 3) consists of fine-tuning copiers 30 (Figs. 10 and 12) that are fixed on the bottom plate K) b. Of current 8, have rolling tracks and a surface corresponding to the Hute profile of the finished handle. Above the copiers 30, with the possibility of rolling along their paths and vertical, two rolls 31 are located (Fig. I 1 and

the flanges 32, which have working surfaces in the form of grooves along the forming roll, correspond to the prof. of the cross section (grades and form the flanges. The rolls 31 are mounted on the slip ()) DN1I11niki 33 slip in K0 iiiycax 34. The drive movement of the rolls 31 consists from the i55 lever system (Fig. 12), which is connected to one storszha with rollers M. a with another () from the top nli-T (JY 9 b. | 1 () ka 8. and p) of the clamping pilipdra 36, whom ) s also pprnirno connected with rollers 31 and the top plate 9 of the block 8.

The knives 15 for separating the levers (Fig. 10) consist of lower cutting knives 37. mounted on copiers 30. On the upper nlit 9 of block 8, the i # bar is fixedly fixed. on which are mounted with the possibility of vertical () 1 about the movement of the package of the sponge-like springs 39 and the clamp 40. At the end of the shtashi 38 there is an upper detachable fire 41. Mechanism 16 of the turn-over (Fig. 3) is in the form of a clamshell cage grips for transfer from the extrusion to the stamp 13 for trimming with the drive from the pneumocene lipdra.

The removal mechanism 17 is made in the form of known devices: a movable carriage with a tong clamp, a turn-off device and an lever pusher with an individual drive through a lever system from a cam distribution shaft (not shown).

Automatic line works as follows.

The blanks are loaded into the storage bin 1 (Figs. 1 and 2) and poured in portions into the bunker orientator 2, which pushes out the blanks in an oriented position on the tray of the loading mechanism and pushing the heater 3, in the inductor of which the blanks are heated to temperature ( The moldings and 1pc are delivered to the roll segment rollers 4. Rollers 4 advance the rolling of workpieces (manufacture of rollers). From rollers 4, the rollers fall onto a chain conveyor 5 and alternate to press 6 to stamp 12 for a pair of hot stamps. of the jaws of the levers (phi-1. 3) of the tooling complex 7 up to the stop 22 (Fig. 4). The rolling 23 is fixed relative to the die of the stamp 12 in gauge 21. The photo-pyrometer 18 sends a command to the working pressure of the press 6. During the working stroke I pressed down the grip handles of the rolling 23, and then the tamping of the levers went on. At idle press 6 from him about the com- pactapparator (not shown) with the transfer mechanism 16, the stamped blank is transferred to P1tamp 13 for trimming, pins 21 are fixed (fig. 7). At the same time, the following procedure is submitted to the stamp 12 h of double stamping of the jaws of the levers. Press 6 from the 18 VC: 1H photopyrometer is sampled and makes working stroke, and P1tamping and trimming occurs simultaneously. When trimming the oblo, first the spring-loaded clamps 24 (Fig. 5) press the handles () to stamp the workpiece, and then the trimming occurs.

kab circumferential matrix 25 (fi | -. 7 and 9). When the press is idling 6, the pods), the ejected pushers 29 (FIG. 9), push the trimmed billet out of the trimming matrix 25, and the spring-loaded clamps 24 press it against the trimming punch 27 (FIG. 7). Thus, the trimmed billet remains on the trimming punch 27, the burrs during trimming fall on the clip 28 to remove the plump (Fig. 8). From the press controller 6 by the removal mechanism 17 (Fig. 3), the trimmed workpiece is picked up by a klepg pick-up, turned by 90 ° and placed on the co-sticks 30 (Fig. 10) of the handle profiling mechanism 14. The next roll is fed to die 13 for trimming. Press 6 from the photopyrometer 18 performs a working stroke. At the same time, first, with the clamp 40 (Fig. 10), with the package of belleville springs 39, the cut-off workpiece is pressed behind the jaws to the copiers 30 and the lower cutting blades 37. The pressing cylinders 36 (FIG. 12) rolls 31 are lowered and pressed by the flanges 32 to the raceways of the copiers 30 with the necessary effort Pp (rasporoy) throughout the entire stroke of the press 6. When the upper plate 9 of the block 8 is lowered through the lever system 35 The rolls 31 are rolled along the tracks of the copiers 30 and the cut piece, the handle profile with a force P, (roll pressure). At the end of the working stroke of the press 6, the levers are separated by an upper cutting knife 4 (Fig. 10) and collide with the mechanism 17 for removing the container (not indicated) during the return stroke of the press. Having made a working stroke, the rolls 31 return, are returned to the initial state when lifting the upper plate 9 bb 8 with the help of the lever system 35 and additional cylinders 36. Then the cycle repeats.

The operation of the entire line is provided from a single automatic control unit (not shown).
