    The invention relates to equipment for processing metal workpieces and can be used for clean cutting in the process of sequential forming. The purpose of the invention is the retooling of multi-stage presses for finishing cutting. The press, equipped with an automatic device for interposition transportation of workpieces, contains a table (P) 1 and a slider 2. Stamps (W) for various technological operations (one of them for finishing cutting) are successively installed on the table 1 and the slider 2. For the installation of the finishing cut-out on the table 1 and the slider 2, the upper insert 9 and the lower insert 10 are fastened. On the inserts 9 and 10, tool holders 11 and 12 are fixed, and on them are the upper 28 and lower 34 stamp plates. In inserts 9 and 10 are placed blocks 13 and 14 hydraulic cylinders. Each cylinder has a control system. Inserts, Ø for finishing cutting, tool holders, cylinders and control system form a set. This kit can be set up on any universal press and installed on any position of a multi-position press as the process proceeds. When you exit the system for final cutting, you only need to dismantle and re-adjust it. 1 hp f-ly, 12 ill.

     removable on the table 1. The blocks 13 and 14 of the hydraulic cylinders have a control system including the engine 15, the pump 16, the accumulator 17, the block 18 for the liquid. Block 13 consists of hydraulic cylinders 23 and 24 and pistons 25 and 26. Blocks 13 and 14 are connected to the control system via valves 27. Hydraulic cylinders 19, 20, 23 and 24 operate independently of each other, and the pressure in them is regulated separately.
    The stamp 4 contains the top plate 28 of the stamp, mounted on it at the lip 29 and punch 30 punches and the safety device 31. In the top plate 28, an ejector 32 is installed connected to the piston 21 by the pusher 33. The stamp is 4со-. it also holds the bottom plate 34, on which the punch 35 is fixed, the tuning plate 36 and the insert 37 for adjustment after regrinding. On the plate 34, a counterpunch 38 and an ejector 39 are mounted. The counterpunch 38 is connected by a rod 40 to a piston 26, the ejector 39 is connected by a rod 41 to a piston

    Mezzda inserts 9 and 10 and, accordingly, instrumental holders 11 and; 12 are mounted fastening upper 42 and lower 43 plates. The tool holders 11 and 12 and the fastening plates 42 and 43 are interconnected by centering pins 44 and screws 45. The position of the plate 28 relative to the plate 34 is fixed by a lock 46. Cresa is equipped with trays 47 and 48 to remove the parts and waste respectively. Stamps 3 and 4 are mounted on a common lower plate 49 and aepxi. plate 50 (figure 1). For fastening the stamp 4 for the final notch in slider 2 and table 1, there are slots -51 (Fig 4) and intermediate upper 7 and lower 8 plates are placed in them.

    The press is punched as follows.
    The metal tape is fed to the first working position in the course of the technological process and the blanking of the workpiece 6 is performed, the following positions are bent and lubricated (r. 5), after which they are mixed to the finishing cutting position by means of an interoperative transportation device, stamp 4, the location of which is determined by the order given by the process.
    At the beginning of the finishing cutting operation, the press slider 2 is in the top dead center (position A in FIG. 12). During the slider 2 running down, the ejector 32 contacts the workpiece sandwiched between the stamp parts 32 and 35 placed on the top 11 and the tool holder 12 (slider 2 is in position B in FIG. 12). The safety device 31 enters the corresponding hole in the workpiece and into the hole provided in the ejector 39 and centers the workpiece (Fig. 8). At the same time, the Pusher 33 or the piston 21 is pressed up (the slider 2 is in position B in FIG. 12). During the further run of the slider 2, the piston 25 is lowered down and with it a punch 35. In this position, the workpiece is clamped by parts of the punch 32 and 35 placed between the upper 11 and 12 tool holders (Fig. 9). The slider 2 is in position D (Fig. 12). Thereafter, a cutting operation begins. Ejector 32 or pistons 21 and 22 are moved upward, and punches 29 and 30 are lowered relative to the counter-punch 38 and ejector 39 or their pistons 25 and 26 (FIG. 10). At the end of this operation, the slider 2 is at the bottom dead center (position D in Fig. 12). Then the pressure of the pistons 21, 22, 25 and 26 is stopped, the slider 2 moves up again (position in Fig. 12). The pressure in the hydraulic cylinder 24 is switched on again and the piston 35 returns to its initial position through the piston 25.
    In W slider 2 piston 25 pushes waste punching, and the piston 26 resets cutting waste. At the end of the pushing out process, the slider 2 is in position I. The slider 2 moves further upwards. At the same time cut down

    on the workpiece hangs on the upper tool holder 11. In the And position of the slider 2, the piston 22 is loaded with pressure and the ejector returns to the rear. When the slider 2 is in position L, the piston 21 is loaded and the cut-out part under pressure of the pusher 33 falls on the tray 47. The separation ends in the position L. In this position, the stamp 4 is again open. The slider 2 returns to the upper dead center — to position A. The cut-out part is removed from the working area along the chute 47, and the waste — along the chute 48.
    The stamp punch can be used as a stand alone. Stamps mounted on the press can be tested and adjusted on single-point presses. After adjustment, all the dies are mounted on common upper and lower plates of the press and equipped with a device for the inter-operational transportation of blanks, in particular, with a clamshell device. When you exit one of the stamps, you only need to remove and re-adjust this stamp. The hydraulic cylinders are powered through a separate unit, switching commands are received from a command device (not shown) of the slider.
    The use of the invention will allow the re-adjustment of the press to carry out finishing cutting on it in a continuous pressure treatment process using additional hydraulic cylinders.
