Abstract

The invention relates to the processing of metals by pressure and can be used in the development of hydraulic press equipment for pressing panels. The purpose of the invention is to reduce the metal intensity of the press and the expansion of technological capabilities. The press contains a fixed and movable beam, a container holder moving along the axis, a container, a sleeve located between the container holder and the container. A high-pressure cavity is made on the inner surface of the container holder. During pressing, a high pressure fluid is supplied to the cavity, which allows the container holder to be used as the outer container holder. 6 Il.

Description

The invention relates to the processing of metals by pressure and can be used in the development of hydraulic press equipment for pressing panels.

The purpose of the invention is to reduce the metal intensity of the press and the expansion of technological capabilities.

FIG. 1 shows a press, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. one; in fig. 4 — node II in FIG. one; in fig. 5 shows the node III in FIG. one; in FIG. 6 a section BB in FIG. one.

The press consists of the following main components. Koteiner holder 1, located between movable 2 and fixed 3 traverses, Inside container holder 1 is the sleeve 4 covered by it, supported by brackets 5 (Fig. 6) located in traverse 2 with the possibility of moving the latter from the rods of hydraulic cylinders 6 perpendicular to the axis of the press. Container holder 1 has the ability to move

along the axis of the press from the rod of hydraulic cylinders 7. Inside the sleeve 4 there is a power container 8 and a holder 9 for a block of dies 10. Along the edges of the container holder, seals 11 - 13 are installed on the mating surfaces of sleeve 4 and container holder 1 . Depending on the installation variant, the seals form cavities 14 located between them for supplying high pressure fluid through the multiplier 15. The container holder 1 rests on the brackets 16 with the punch 17 fixed inside them with the possibility of their movement perpendicular to the axis of pressing from the rods of the hydraulic cylinders 18 for loading the blanks 19 and servicing the punch 17 (cleaning, lubricating, controlling dimensions, etc.), on a fixed traverse 3 has a working cylinder 20 with a rod 21 in contact with the movable crosshead 22, which

through rod 23 it is connected to crosspiece 2. In support 2, there is a support sleeve 24 (mouthpiece) with the possibility of its extraction and feeding with hydraulic rod 25. In the grooves of the holder 1, ribs 26 are wound from high-strength prestressed tape.

The work of the press is carried out in the following sequence.

To the end of the workpiece 19 serves the punch 17 with the brackets 16 using the rods 18 of the hydraulic cylinder. After this, the multiplier 15 supplies high pressure fluid in the cavity 14. As a result, the radial force is transmitted to the sleeve 4 and through it to the power container 8 and the holder 9. Then the working fluid is fed into the cylinder 20. From interaction with it, the rod 21 moves and moves through the yoke 22 and t ha 23 traverse 2 in the direction of the container holder 1, the sleeve 4 and rigidly fixed on the traverse 2 by means of brackets 5 sleeve 24 moves and pulls the container 8 on the punch 17. The workpiece 19 through the matrix 10 is pressed out before full ochego stroke of the press. After that, the multiplier 15 relieves the pressure of the working fluid in the cavity 14 and when the working fluid interacts with the rods

the cylinders 7 are retracted movable cross braces 2 and 22 with the container 8, the yoke 9 and the die 10 to the initial position. Then open the bracket 5 and the movement of the rod 25 is removed from the cavity of the sleeve 4, the sleeve 24, the holder 9 and the matrix 10 with the molded panel 27.
