SU383621A1 - VIBROSTAND FOR FORMING PRODUCTS FROM POWDER MATERIALS - Google Patents

Description

one

A vibrostand for molding articles from moth materials, containing a frame consisting of upper and lower taps, interconnected by means of wires, vertically mounted H: a her mat, a boarder with a rotary shaft and a punch, placed one end in matr; nce.

However, the known structure of the aisle complex is complex and is characterized by the limited range of parameters of the processes of vibratory molding.

In order to expand the frequency range of vibration, the proposed stand is equipped with a spring-loaded split but forming split sleeve, which encloses the free end of the punch and is mounted in the conical axial bore in the upper traverse.

The drawing shows a general view of the proposed stand.

The vibrostand consists of a frame /, a support 2, in which, with the possibility of rotation around a vertical axis from a drive with an adjustable angular velocity (shown on the drawing), the base 3 of the NCF 4 fixed on it is installed, containing a central rod 5 (in the case of forming a circular section section ), poalso-6, installed in a slotted cone sleeve 7, mounted with spring 8 and pin 9 in a conical socket T, ravers 10, reinforced by shtang // and plate 12 on a table 13 in an ibrostend. In the upper part of the punch 6 s. Mounted voroika 14 for powder powder

material, in the lower part of the punch and there are holes 15 for nodal powdered material in the extrusion zone.

The vibration table works as follows. Remove spring 8, install force

the friction between the punch 6 and the ivOHyAHAA split sleeve 7, the magnitude of which is determined by the parameters of the vibratory molding process, in particular by the molding pressure (the punch 6 touches the bottom of the matrix-).

Powder material is poured into ravens 14, including a stand and a rotation drive (not shown).

Pua, nsoi 6 starts to insert with frequency

and with the amplitude of the cutter mounted on the inside of the strand, the powder material passes through the holes 15 under the punch 6 into the pressing zone, as the height of the product 16 is increased by holding the punch 6,

cone sleeve 7, rises.

At the end of chi: klama molding products

the duration of which is due to the height

product and processing parameters, demoit matrix 4 and the central rod 5 with

base 3 and remove article 16 from matrix 4.

Subject invention

Shake table for molding. a product made of powder materials, containing a frame consisting of upper and lower beams, connected to each other by weights, vertically

Matrix mounted on it with a rotary drive around its axis and poi.ison: placed with one end in the matrix, characterized in that, in order to expand the range of vibration frequencies, it is equipped with an integrally split but conical sleeve that clamps the free end The punching hole and smithrowing are in the conical axial bore in the upper bead.
