() DEVICE FOR BRIQUETTING OF BULK MATERIALS

The invention relates to the processing of metals by pressure, in particular to the design of devices for the briquetting of bulk materials.

According to the main author. St. No. 812b01 is known. A device for briquetting loose materials, comprising a mold fixed on the frame and two punch plates mounted therein with the possibility of oncoming movement. with the drive, as well as two wedges with springs, the side walls of the mold are made inclined relative to the direction of movement of the punches, one of the punches being made composite in the form of a disk with a central hole and washers placed in it, and the wedge mounted on the composite punch disk are articulated with inclined planes of the mold and springs connected to the frame of the DUT. The purpose of the invention is to increase the reliability of the device.

This goal is achieved in that the Device for briquetting bulk materials, containing a mold fixed on the frame and installed in it with the possibility of two moving punch with a drive, as well as two wedges with springs, lateral molds of the mold are made inclined relative to the direction of movement of the punches with one

10 of the punches are made composite in the form of a disk with a central hole and washers placed in it, and the wedge is mounted on the composite punch disk, articulated with inclined planes of the mold and connected by springs to the frame, provided with a flexible element placed between the punches and inclined walls moveable molds

20 along the latter.

FIG. D shows a diagram of the device; FIG. 2 shows a variant with a flexible element connected to the driven ones.

drums-, in fig. 3 shows a diagram of the device at the moment of the start of pressing, FIG. 1: a diagram of the device at the time of termination of pressing.

The device comprises a mold 1 in which an upper punch 2 and a lower composite punch consisting of disc 3 and washer k are mounted. The disk 3 is equipped with 5, connected by springs 6 with the 7Punson 2 bed, connected to the drive 8, and the disk 3 and the washer L are connected according to the transfer 9 and 10. The wedge 5 is mounted on a flexible element 11, which can be made in the form of an infinite metal ribbon covering the side inclined walls of the mold, or in the form of a metal tape wound on the drive drums 12 and 13.

. The device works as follows.

When loading the mold, the disk 3 and the washer k are in the lowest I position, and the wedge 5 is separated. After loading the bulk material, the punch 2 is set / filled and the wedge 5 and the disc 3 are lifted. and, when mixed, move together with

flexible element 11 on the side NAC-. the inner walls of the mold. After mixing the wedges 5, the final pressing is carried out by the punch 2 and 5 with the washer C at their oncoming movement.

After ejection of the briquette, the wedge 5 is diluted for the next dose selection and then the cycle of operation of the device is repeated.

The application of the proposed device allows you to expand the range of extruded material.
