Description

(54) ROLL PRESS

I

The invention relates to mechanical engineering and can be used for pressing articles from powder and paste-like materials.

A roller press is known, which contains a drive press ring with matrix holes and articulated rolls, on the pressing surface of which evenly formed recesses are aligned in the pressing zone with the matrix holes flj.

However, in a known press, it is impossible to press the product in the form of plugs from pasty materials.

The purpose of the invention is to improve the quality of finished products and expand technological capabilities by expanding the range of processed materials and products.

This goal is achieved by the fact that in a press containing a drive press ring with matrix holes and articulated rolls with an i

the indentations combined in the extrusion zone with the matrix holes are numbered, the press ring is made in the form of two discs, the matrix holes are made in the latter, their axes parallel to the rolls axis, and the rolls are articulated with the discs with their ends.

The press consists of mounting the rollers 1 on the support device 2, press rings 3 with matrix holes 4, support disks 5 with directional holes 10 CHECKS 6. On

Claims (1)

IS 7 and 8, connected with the drive (not shown), are installed rolls 9, along the entire length of the rolls evenly spaced around the circumference of the recession IO with notch 11 to hold material in them. The recesses 10 form holes at the point of contact of the rolls 9, the diameter of which is equal to the diameter of the matrix holes 4. The ends of the rolls 9 are adjacent to the ends of the press rings 3. Gears 12 and 13 are mounted on the shaft 7. The teeth 14 are cut on the outer surfaces of the press rings 3. The teeth 15 are cut on the outer surfaces of the support discs 5. The rolls 9, gears 12 and 13 are fixed on shafts 7 and 8 with pins 16. Sideways, coaxially with the matrix holes 4, the needles 17 are mounted. Mvdu press rings 3 coaxially with matrix ridges 4 mounted pushers 18. Above the rolls 9 mouth copulating download bunker with 19. The pushers 18 are intended to remove dll sleeves 20. Press works as follows. When the shafts 7 and 8 rotate towards each other, the rolls 9, gears 12 and 13 and the press rings 3 meshed with the matrix holes 4 and the supporting disks 5 with the guide holes 6 rotate simultaneously with each other in such a way that the holes holes 10 of the rolls 9, matrix holes 4 of the press rings 3, and directions to the hole 6 of the supporting disks 5 in the pressing zone are coaxial. Before entering the matrix holes 4 of the press rings 3, a special device (not shown) is inserted into the pressing zone of the needle 17 by the matrix holes 4. In this case, the needles 17 pass through the guide holes 6 of the supporting discs 5 and center them. The source material is loaded into the hopper 19, from which the material is picked up by the rollers 9, compressed in the direction perpendicular to the matrix holes 4, and thereby flows in the axial direction, filling the matrix holes 4 in the pressing zone. Since the needles 17 are inside the matrix holes 4, the device is pressed into articles in the form of sleeves 20. Upon further movement of the press rings 3, the material is moved and removed by the rolls 9 from the ends of the pressing rings 3 and from the needles 17 to the part $: ah between press rings 3. After the material has been removed from the needles 17 in the areas between the press rings 3, the needles 17 are replaced from the matrix holes 4 and retracted to their original position, and the sleeves 20 are pushed out of the matrix holes 4 by the pushers 18 4. The economic effect is provided by increasing qualities Started manufacturing and the expansion of technological capabilities. Invention Roller press containing a drive press ring with matrix holes and articulated rolls, on a pressing surface of which evenly made recesses combined in a zone of pressing with matrix holes, characterized in that in order to improve the quality of finished products and expand technological opportunities by expanding the range of machined materials and products, the press ring is made in the form of two discs, the matrix holes are filled in the latter, and their axes are parallel Yelnia roll axes, and the rollers are coupled to the wheels by its ends; Sources of information taken into account in the examination 1.
