Description

The invention relates to the field of metal forming, in particular to universal blocks for sheet metal forming.

The aim of the invention is the expansion of technological capabilities.

FIG. 1 shows a block, a general view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. one; FIG. 5 is a section B-B in FIG. 2

The universal unit contains the upper 1 movable v, the lower 2 fixed plates, in which are mounted the fasteners 3 dp of fastening the plates 4 and 5 of the interchangeable bag (for example, of the combined action), made with the ability to perform a vertical reciprocating movement under the action of a pneumatic actuator and rotate at a given angle in the horizontal plane around its vertical axis. A compression spring 7 or a rubber plate (not shown) is installed below the lower movable puller 6 of the replacement bag. In the upper plate 1, perpendicular to its supporting plane, adjustable pressure rods 8 are screwed with locking nuts 9 placed on them.

Under the pressure rods 8 above the bottom plate 2, the brake carriages 10 are placed with the gripping bodies 11 and the adjusting screws 12 screwed into them, which come into contact through the bearing washers 13 with the return springs 14.

In addition, guide columns 15 and 16 are perpendicular to each other in the brake carriages 10. Columns 15, which are parallel to the feed direction of the material to be processed 17, are provided with feed carriages 19 connected to each other with pneumatic grips. A pneumatic cylinder 20 is mounted in one of the carriages 19, by means of which the material 17 is fed at a predetermined pitch.

Springs 21 are placed at the ends of the columns 16 installed in the bottom plate 2 perpendicular to its support plane.

The universal unit operates as follows.

The replaceable package is installed at the workplace of the support plate 1. Then, from the pneumatic network, channels (not shown) drilled in plates 1 and 2 are supplied with an energy carrier — compressed air, under the action of which they simultaneously rotate in a horizontal plane around their vertical axis and lowering the tacks 3, This causes the pressing of the plates 4 and 5 of the interchangeable package to the base plates 1 and 2.

Further, by rotating the bores 12, the support planes of the brake carriages 10 and the movable puller 6 are combined.

To ensure that the puller 6 and the carriages 10 are simultaneously lowering in one plane, the sizes of protruding parts of the pressure rods 8 protruding from the plate are fixed and fixed by nuts 9. Then the press is turned on and the air coming from the pneumatic network is fed into the piston cavity of the cylinder 20, which is rigid connected to one of the brake carriages 10. The pneumatic clamps of the clamp type in the feed carriages 19 are in the raised position. When the piston cavity of the cylinder 20 is filled with air, the feed carriages 19 move from left to right. In this case, the gripping bodies 11 of the brake carriages 10 clamp the material 17 and keep it in a stationary position. The pneumatic conveyor carriages 19 slide over the material 17. At the end of the stroke, the carriage 19 is set to its original position to feed the material at a predetermined step from right to left and under the action of the upper movable part, the puller 6 is lowered and the springs 7 are compressed. At the same time, the rods 8 are pressed on the carriages 10 and move them down the required stroke along with the feeding carriages 19, which are placed on the guide columns 15.

In doing so, the columns 16 also fall down and loosen the compressive force of the springs 21, and the screws 12, resting on the support washers 13, compress the return springs 14.

In this way, the puller 6, carriages 10 and 19 and the material 17 to be processed are displaced during operation of the stamp (package) in the vertical direction together (simultaneously) and in the same plane to each other.

to a friend.

During the return stroke of the press ram, the plate 1 and the pressure rods 8 secured therein are lifted up. At the same time, the springs 7 and 14 are depressed, which raise the puller 6, the carriages 10 and 19 and the material 17 lying on their supporting planes.

At the moment when the upper movable part of the replaceable package comes out of contact with the stripper of rods 8 with carriages 10, the pneumatic valve is switched, air enters the pneumatic clamps of the feed carriages 19 and the material 17 is clamped up. The air moves upward into the rod cavity of the cylinder 20 and the carriage

the clamp type 19 together with the clamped material is moved along the guide columns 15 from right to left. The material is fed to the specified step. In the extreme upper position, the feed cycle is stopped and the pneumatic valve is switched.

At the start of the downward movement of the press slide, the cycle of return (cocking) of the feed carriage 19 is repeated.

The effect of using the proposed technical solution, as compared with the known one, is that the range of interchangeable stamp packages increases, which can be used when working in automatic mode for this universal unit, and in the latter, thanks to the design, not only stamps can be used - packages of simple action (cutting, punching), but also combined.
