SU361105A1 - DEVICE FOR FORMING PRODUCTS FROM POWDER MATERIAL - Google Patents

Description

one

The invention relates to the production of blanks of powder materials.

A device for forming blanks of powder materials is known, including an iBOKpyr rotary vertical axis matrix and a punch mounted in a mechanical unbalance vibrator moving vertically along rails. The disadvantages of the known device are the unsatisfactory quality of the products, the complexity of the KONOT1RU1KTsII, energy intensity, 1green intensity.

The invention eliminates the described disadvantages due to the fact that the device is equipped with a loading mechanism for the heated powder in the forming zone and irrigating it with a binder, made in the form of a rotary shaft around its axis and an axially movable cylinder with a longitudinal chute for backfilling the powder in it, as well as along it is a heated tube connected to the power supply of the binder and having openings for its supply. The cylinder is cantilevered in a support mounted on the frame and placed inside the horizontally mounted matrix.

FIG. 1 shows the device; in fig. 2 - section A-A on f-ig. one.

The device consists of a frame 1, to which

by means of flat springs 2, the platform 3 is attached with a vibrator 4, the amplitude of oscillation of which is parallel to the axis of rotation of the matrix 5 mounted in rolling bearings 6

buildings 7.

A container 8 is mounted on the frame / for heating the paroschka material 9, the container 10 for melting the binder 11, the mechanism 12 for loading the material to be fed into the forms of the molds and irrigating it with the molten binder, made in the form of a cylinder with a longitudinal chute 13 installed in the cantilever a support 14, movable in the axial and circumferential direction by means of the handle 15, with a tube 16 mounted in it with openings for the exit of the binder, which is heated by a spiral 17. The matrix 5 is driven by a V-belt transmission 18 from the electric motor (in the drawing

not shown).

The device works as follows. Filling the pilinar chute 13 with the required amount of powder material (depending on the geometric dimensions) | In the product

and processing modes), the loading mechanism 12 is introduced into the forming zone, the matrix 5 is driven and the vibrator 4 is turned. The cylinder 13 is rotated around the horizontal axis, loading the glomerular material into the internal cavity of the rotating and vibrating

the matrices 5 return the mechanism to the initial position, open the valve of the container 10, feed the loose binder // through the tube 16 heated by the spiral 17 into the forming zone and irrigate the moldable powder material.

After the completion of the molding cycle for the product 19 (the duration of which is determined by the processing parameters, the properties of the molded product and its geometrical dimensions), the latter is removed from the matrix 5, and the cycle is repeated.

Subject invention

A device for molding articles from a powder material, comprising a vibrator mounted on the frame and a matrix associated with it with a drive for rotating it around the axis, characterized in that, in order to improve the quality of the products. it is predominantly porous, it is equipped with a mechanism for charging the heated powder to the forming zone and irrigating it with a binder, made in the form of a cylinder rotatable around its axis — and moving axially in the axial direction

a chute for filling powder into it, as well as located along a heated tube that connects to the power source of the binder and the sinking feed hole, while the cylinder is cantilever mounted in a support mounted on the frame and placed inside a horizontally mounted matrix .
