The invention relates to devices for producing periodic profiles from dispersed materials, in particular to molds for pressing periodic articles from metal powder.

The purpose of the invention is to expand the product range.

The drawing shows the scheme of the device.

The device includes a housing 1 having

the movement of one of the supports of the rolls ahead of the other. At the same time, in the process of operation of the device, the support rolls have the possibility of reciprocating movement. At the same time, the punch 5 acts and, and the material and squeezes it between the rollers.

Due to the location of the axes of each of the rolls with eccentricity relative to the axis of the rods of the intersection of the axes of the rods

rectangular working cavity (chamber Yu at an angle of 60-170 ° at the location

press) 2, into which the powder is loaded, the rolls 3 mounted with the possibility of rotation in the movable supports 4, which are located in the hull projections made at an angle opposite to | side walls of the housing. The axes of these openings form an angle of 60-170 °.

In the pressing chamber there is an organ movable relative to its walls (punch 5), in order to move the processed

the points of their intersection outside the line connecting the centers of the rolls, when the rolls move asynchronously, the axis of the product deviates from the vertical axis to the side, which allows to obtain products with a more complex curvilinear surface as compared with the known device, as a result of which the complex range of products from various dispersed materials. If necessary, receive from the material. Hydraulic cylinders 6 with shafts20 and limited length between rolls

They are used to move and fix on or above them, as well as between the preparation of the rolls in the openings of the body. Oski pre-installed each of the rolls are located with the ex-rate,

centricity relative to the axis of the rods. The device allows to produce

i The axes of the hydraulic cylinders intersect I between them at an angle of 60-170 °, while the first point of their intersection is located outside the I line connecting the centers of the rolls, i When the angle is less than 60 °, the stiffness of the i-beam is formed by the working cavity

products having a variable cross section and variable curvature in length.

Claims (1)

The invention The apparatus for manufacturing a batch body and a side cavity in which -, Q of the profiles, mainly from the displacement, moves the movable support, becomes persian materials, comprising the body I insufficient for stable work with a pressing chamber, equipped with one I device. At an angle of more than 170 °, the conditions of the side moving relative to its walls  work rolls will be almost the same body to move the processed material and installed on the opposite side of the right side of the rollers mounted in the supports with the possibility of rotation in them, hydraulic cylinders and rods for moving and fixing the rolls in the projections of the body, the axes of which are at an angle to the axis of the body ., which limits the product range. : The device works as follows. I In the initial position, the rolls are pressed together. The powder material is poured into the pressing chamber 2. Then him compacted to a predetermined density of the material 40 in the chamber, differently m 5. Depending on the desired cone; figure out the surface of the press product, the hydraulic cylinders 6 operate in accordance with the program that provides the specified product profile. The roll supports can move at equal distances synchronously, or they may not synchronously when 45 In order to expand the product range, the axes of each of the rolls are eccentrically relative to the axis of the rods, and the axes of the rods intersect each other at an angle of 60-170 °, while their intersection point is located outside the line connecting the centers of the rolls. the movement of one of the supports of the rolls ahead of the other. At the same time, in the process of operation of the device, the support rolls have the possibility of reciprocating movement. At the same time, the punch 5 acts and, and the material and squeezes it between the rollers. Due to the location of the axes of each of the rolls with eccentricity relative to the axis of the rods of the intersection of the axes of the rods the points of their intersection outside the line connecting the centers of the rolls, when the rolls move asynchronously, the axis of the product deviates from the vertical axis to the side, which allows to obtain products with a more complex curvilinear surface as compared with the known device, as a result of which the complex range of products from various dispersed materials. If necessary, to obtain izdeizdeli, having a variable cross-section and variable curvature along the length. Apparatus of the Invention A device for the manufacture of a material in a chamber, characterized by In order to expand the product range, the axes of each of the rolls are eccentrically relative to the axis of the rods, and the axes of the rods intersect each other at an angle of 60-170 °, while their intersection point is located outside the line connecting the centers of the rolls.
