Said mechanism provides process of slider movement after first pass extreme position to position for implementation of second process operation.EFFECT: result is performance of two technological operations or two passes stamping in one press stroke.1 cl, 1 dwg
FIELD: manufacturing technology.SUBSTANCE: invention relates to design for presses, particularly, to forming of ceramic articles. Structure for press comprises having resistance structure consisting of at least one having resistance element containing flat ring-shaped or arched element. Inside arched element there are two opposite surfaces, diametrically opposite to each other, between which can be installed at least one power element to perform pressing action by pre-compression object or material between two bodies so that said opposite surfaces receive equal and opposite reaction pressing action. At that, at ends of said surfaces there are through slots. At that, every through slot has preset width, starts from end of corresponding opposite surface and passes along the curve, having at least first section and at least second section. Edge of outer surface of first section is connected with side surface of vertical or almost vertical part of ring-shaped or arched element, limiting sideways space to accommodate power element. Second section is connected to first section and concave in same direction as first section. Note here that through slots are located symmetrically at least relative to central vertical axis of ring-shaped or arched element, perpendicular to opposite surfaces. At that, in each through slots there is at least one plate, opposite surfaces of which are intended for contact with surfaces facing each other, limiting that through slot.EFFECT: technical result is reduced weight and overall dimensions of design, simplified design.10 cl, 3 dwg
FIELD: recycling.SUBSTANCE: invention relates to press equipment for briquetting crushed solid household or loose process wastes. Installation consists of a bed, on which there are inner and outer rotors with shifted relative to each other vertical rotation axes. Working surfaces of rotors at closure form a closed briquetting volume. Outer rotor has a disk shape and is equipped with pushers of formed briquettes, which are controlled by track former. With external rotor is attached a circular platform with pushers. Rotary drive is connected with external rotor. Inner rotor is installed with possibility of free rotation. External rotor working surface is formed by continuous row of briquetting moulds, separated by teeth. Track guide plate is arranged in form of curved line fitted on stationary cover.EFFECT: providing higher reliability of installation and higher density of obtained briquettes.1 cl, 3 dwg
FIELD: process engineering.SUBSTANCE: invention relates to production of two-ply pellets. For this, the first powder mix is first, placed on the die plate and, then, the second powder mix. The first powder mix contains pharmaceutically active substance and the binder. The second powder mix contains the binder. The second powder mix composition differs from the first one. Then, the first and second powder mixes are compacted at the mould plate to get the pellets to be subjected to RF-radiation for the period sufficient for activation of the binder and fusion of pellets to a two-ply pellet. Pellet density makes approx 0.8 g/cm3. Pellet on the tongue is sucked off in not over 30 s.EFFECT: higher efficiency of the process.18 cl, 14 dwg, 10 tbl, 12 ex
FIELD: machine building.SUBSTANCE: pelleting press contains a ring matrix, press roller with shell, located on the cylindrical eccentric bushing, and pinion carrier. The eccentric bushing has cone shank located on one its end coaxially with the cavity. At the another end of the bushing coaxially with the cavity there is band with elements for the torque transfer. The pinion carrier is made with the eccentric axis having the cone cavity, with thread hole and with cavity. The cone shank of the eccentric bushing is connected detachably with the cone cavity of the eccentric axis. In the eccentric axis cavity a bolt is installed, it is connected with the thread hole of the pinion carrier, and is made with the shoulder. The shoulder diameter exceeds diameter of the eccentric bushing cavity. The shoulder is located in the cavity between the cone cavity of the eccentric axis and with thread hole of the pinion carrier. At that the possibility of the shoulder interaction with the cylindrical eccentric bushing is ensured, and its contact with the pinion carrier is excluded.EFFECT: improvement of the pelleting press capability and reliability.3 cl, 4 dwg
FIELD: process engineering.SUBSTANCE: invention relates to equipment for production of pellets from powders, for example, the nuclear fuel pellets. Claimed device comprises the powder dispenser (6) and table (2) with cavities (4) for the powder. Said dispenser (6) displaces over the table (9) and includes the casing composed of the cover, two side walls and two end walls. Said cover is coupled with at least one pipe (10) for powder feed from the bin. Guide rollers (26) are used to guide the dispenser (6). The latter is pressed to the table (2) by pressure rollers. Said pressure rollers can up the dispenser pressure applied to the table.EFFECT: higher reliability and simplified design.20 cl, 10 dwg
FIELD: process engineering.SUBSTANCE: this invention relates to pressure pad for hot press. Claimed pressure pad comprises the flat textile article composed of threads or fibres and silicon elastomer. The latter is produced by cross-linking of silicon rubber, and/or copolymer produced by cross-linking of silicon rubber and fluorosilicon rubber, and/or copolymer produced by cross-linking of silicon rubber and fluorosilicon. Note here that said silicon elastomer and/or copolymer are cross-linked additively.EFFECT: higher quality of moulded article.17 cl, 2 dwg
FIELD: medicine, pharmaceutics.SUBSTANCE: group of inventions refers to pharmaceutics and is applicable to produce a solid galenic form of a preparation for oral administration. A device (1) for connection of a medicinal capsules (A, B) by an adhesive joint comprises a matrix (10), which limits a capsule (A, B) packing cavity (15) and a space (16); the cavity and space are separated from each other by means of a deformable wall (14) of the matrix, which is adjusted to transform its space (16) smoothly under air exposure from a first configuration, wherein the cavity (15) comprises capsules of an adhesive (Z) applied in between, into a second configuration, wherein the wall (14) deformed elastically encloses the capsules at least partially to squeeze these capsules between the deformable wall and a cavity bottom to align and press them to each other. The group of inventions also refers to an assembly for capsule connection by the adhesive joint, comprising the above device.EFFECT: group of inventions provides damaging the capsules while fastening them by adhesion and ensured higher performance of the assembly for the adhesive joint of capsules.15 cl, 6 dwg
