-4 INS The invention relates to the processing of metals by pressure and can be used to mechanize laborious operations during forging on presses. A device for feeding a tool into a working area of a press comprises a base with a housing located on it, on which are mounted a tool mounted on rods and a drive for moving a housing with power cylinder. However, the known device does not allow a different tool to be fed into the work area in any sequence, which limits its technological capabilities. The purpose of the invention is the expansion of the technological capabilities of the device. For this, the device case is manufactured in a platform with a support collar on the outer diameter and a trunnion in the middle part, with a pivoting clip installed on it with a stepping mechanism of rotation, carrying an instrument on the rods, and on the base of the RI a platform is fixed between the press and the platform roller, while instrumental rods are equipped with rollers that interact with the support ring of the platform and the roller rack. The step mechanism along the gate is made in the form of two located on the basis of driving power cylinders with a common rod, kinematically connected with the help of levers with the crackers provided on the swiveling yoke. 1 shows the proposed device, a general view, in FIG. 2 - the same, view along arrow A in FIG. on fig.Z - section BB in figure 1; figure 4 - section bb In fig.Z; on fig.Z - section GG on fig.Z. The device for feeding the tool into the press working space contains the base 1, on which the slider 2, case 3 is mounted. The case 3 is made in the form of a lifting platform connected by way 4 to the rod 5 of the drive cylinder b, also mounted on the slider 2. The cylinder body b serves as a guide when the platform moves. In the upper part of the housing 3, the support ring 7 and the support bracket 8 are made. On the slider 2, the support 9 is also mounted, supporting the support roller 10. The support 9 passes through the through window of the platform of the housing 3, while the axis of the support roller 10 in the lower position of the platform 1 1 is aligned with the location of the support ring 7. A trunnion 11 is made in the middle part of the platform of the housing 3, on which a swivel holder 1 supporting rods 13 are fitted, equipped with shock absorbers 14 and swivel rollers 15. In the holder 12 on six axles 16, six rods 13 are mounted, for example, free (upper) the ends of which are fixed working tool 17 - ax, prissech, firmware, etc. The yoke 12 is kinematically connected with the step mechanism (see Fig. 4), which includes the driven cylinders 18 and 19 and the pivoting lever 20 with two spring-loaded pins 21, which engage with the croutons 22 fixed on the yoke 12 The slider 2 is associated with a horizontal displacement cylinder 23. On the slider 2 there are also pumps: I set 24 and control device 25. The base 1 of the device is clicked onto the foundation adjacent to the base 26 of the press (see Fig. 2). The device works as follows. In the initial state, the platform of the housing 3 is in its lowest position. The rods 13, in the free ends of which the tool kit 17 is installed, are supported by the rollers 15 on the support ring 7 and in a vertical position. Before starting work on. the position of the tool half into the working space of the press sets the tool necessary for the operation, for which pressure is supplied to the drive cylinder 19, cylinder rod 19 turns the lever 20 associated with it, and the fingers 21 engage with the corresponding crackers 22 12, turning the last at a given angle. When the yoke 12 is rotated, the rollers 10 of the rods 13 roll over the support ring 7, with one of the rods being mounted onto the roller 10, from which the tool 17 is then fed into the working space of the press. By the working stroke of the cylinder 18, the lever 20 returns to its original position, and the fingers 21 are mounted by the bevels of the crackers 22. Pressure is applied to the drive cylinder b. The rod 5 connected by the rods 4 to the platform of the body 3 lifts the body 3 to the upper (predetermined) position. The rod 13, supported on, the roller 10 rotates in a vertical plane and takes a horizontal position, resting on the support bracket 8. In this position, pressure is supplied to the horizontal movement cylinder 23, which moves the slider 2 in the direction of the press, and the tool 17 is installed in the specified position on the forging 27 (see Fig.2). When performing a technological operation - cuttings, cuttings, clamping, etc. - tool 17 under the influence of the upper die head penetrates into the metal, forgings 27. At the same time, the bracket 28 of the movable traverse of the press presses the rod 5 of the cylinder b, providing simultaneous lowering of the platform of the housing 3 with the other 12. After performing the technological operation of the traverse of the press with the bracket 28 moves to the upper position and releases the platform of the housing 3, which by the rod 5 of the cylinder 6 also moves to the upper position and removes the tool 17 from the forging 27. In this position the cylinder 23 moves the slider 2 in the original The battery status. The rod 5 of the cylinder b moves the platform of the housing 3 to the lowest position, while the rod 13, which was in a horizontal position, rests on the roller 10, and rotates on the hinge axis 16, occupies the original (vertical position. Further operation of the device proceeds in the above sequences.
