The invention relates to the processing of metals by pressure and can be used in the manufacture of parts such as glasses on horizontal hydraulic presses.

The aim of the invention is to increase productivity and reduce energy consumption by combining the workpiece feed operations to the machining position and the movable stop at the entrance to the matrix assembly for flashing the original workpiece, as well as improving the quality of the products by ensuring the accuracy of centering the workpiece being pierced relative to the working tool.

I FIG. A device is shown, totaling 15 laziness in the power cylinder 5, its stock moving is I type; in fig. 2 shows section A-A in FIG. 1 snaps the slider 6 with the punch holder 7 and

the position of feeding the movable stop to the mat-punch 9. The latter forgives the workpiece 24 with the shaping of its bottom part, the support for which is the stop 10.

rich knot; in fig. 3 - the same, but with the movable m. Emphasis; in fig. 4 - the same, at the initial moment of retraction of the rolling stop.

The device contains a front cross member 1 with a matrix node 2 connected by means of columns 3 to a rear cross head 4. And in the latter there is placed a load cylinder 5, ne20

When the punch 9 is inserted into the workpiece 24, the latter increases in diameter, the bed 13 deflects according to the outer shape of the workpiece, without disturbing the centering of the workpiece 24 relative to the matrix node 2. The deviation occurs due to the reducing force on the slider 6, moving the elastic elements 14, on which is placed along the column 3. On the slider 6 there is mounted a punch holder 7 passing; through a through hole centering tra-; versions 8, installed with the possibility of free-: free movement along the columns 3. The punch is fastened in the punch holder. 9 lia: the entrance to the matrix node is movable; A new anvil 10 associated with the drive of it; displacement in the form of a power cylinder 11. In one piece with a movable stop 10 is 30

New lodgement 13.

Before the end of the firmware for cooking 24 punch 9, centering traverse 8 due to the frictional forces of punch holder 7 in the opening of traverse 8 moves along columns 3 synchronously with punch 9 and thereby prevents it from moving away from the firmware axis.

At the final stage of the firmware, the centering yoke 8 reaches the removable yiiopoB 23, the support pad 12 for the cradle 5 draws the punch, and then the firmware process

13 for the original billet, which is installed at the support site by means of elastic elements 14 with the possibility of compensatory movement in the direction: perpendicular to the pressure axis. Lodgment

is in an established stage.

When flashing, the rods 17 fixed to the slider with restrictive recesses 18 move together with the slider 6. Since the electromagnets 20 are made in the form of a prism at the beginning of the movement, the slant wall of the slider is inclined to de-energize, the opening 15 of which 19 slides across the surface of the rods 17 and

The supply of the movable stop 10 to the matrix node 2 is rotatable on the axis 16 and spring-loaded to the pressure axis. On the slider 6, rods 17 are rigidly mounted with restrictive recesses 18 at their ends, passing through holes made on a fixed rear traverse 4. On the latter, folding stops 19 are mounted on the axles in the form of pairs of brackets 19 installed with the possibility of simultaneous rotation of the brackets in each the pair and the interlock with the recesses 18 of the chtang 17. The free ends of the brackets in the pair are connected by means of a spring (not shown). One of the clips of the pair sv-: on with an electromagnet 20.

The device also has a mechanism for the piece-by-piece delivery of source blanks (not shown) with

at the approach of the restrictive notches 18 stops are included in them. The slider 6 with the punch 9 stops, before this the stop grooves 18 of the rods 17 are mounted on the slider 6 at such a distance that the punch 9 completely forms the internal cavity of the workpiece 24 with a predetermined bottom thickness. After that, the slider 6 of the device is retracted for a small distance in the reverse direction and the movable stop 10 with the lodgement 13 is retracted to its original position (Fig. 3). At the same time, the pivoting oblique wall 15 is deflected on the axis 16, allowing the removal of the lodgement 13 from under the workpiece 24.

The forces of the elastic elements 14 and the springs of the rotary wall 15 are designed in such a way that when the billet 24 is fed to the axis

tray 21. At the exit of the matrix node mounted tray 22 reset. On the columns 3 in front of the matrix node 2 are placed removable stops 23.

The device works as follows.

In the initial position, the movable stop 10 is in the extreme right position (Fig. 3). From the loading chute 21, the billet 24 is heated to the cradle 13. The cylinder 11 is supplied with a movable stop 10 with the cradle 13 and the billet 24 to the machining axis. The stop 10, located perpendicular to the pressure axis of the tray, overlaps the entrance to the matrix node 2. When pressure is applied to the power cylinder 5, its stem moves slider 6 with the punch holder 7 and

When the punch 9 is inserted into the workpiece 24, the latter increases in diameter, the bed 13 deflects according to the external shape of the workpiece, without disturbing the centering of the workpiece 24 relative to the matrix node 2. The deviation occurs due to the compression of the elastic elements 14, on which the

New lodgement 13.

Before the end of the firmware for cooking 24 punch 9, centering traverse 8 due to the frictional forces of punch holder 7 in the opening of traverse 8 moves along columns 3 synchronously with punch 9 and thereby prevents it from moving away from the firmware axis.

At the final stage of the flashing, the centering yoke 8 reaches the removable yiiopoB 23, stops and then does not center on the approach of the restrictive notches 18, the stops enter them. The slider 6 with the punch 9 stops, before that the restrictive undercuts 18 of the rods 17 are mounted on the slider 6 at such a distance that the punch 9 completely forms the internal cavity of the workpiece 24 with a predetermined bottom thickness. After that, the slider 6 of the device is retracted a short distance in the opposite direction and the movable abutment 10 with the lodgement 13 is retracted to its original position (Fig. 3). At the same time, the pivoting oblique wall 15 is deflected on the axis 16, allowing the removal of the lodgement 13 from under the workpiece 24.

The forces of the elastic elements 14 and the springs of the rotary wall 15 are designed in such a way that when the billet 24 is fed to the axis

machining, they sufficiently reliably center the workpiece 24 relative to the working tool, and when the movable stop 10 is withdrawn from the treatment area, the bed 13 and the swivel wall 15 are deflected due to 5 deformation of the springs, without disturbing the centering of the punch 9 with the workpiece 24 relative to the matrix assembly 2.

Further electromagnets 20 are included,
