Description

The known automatic hydraulic presses for briquetting metal chips cannot perform a sufficiently rhythmic dosing of the material to be compressed, due to the presence of a number of design flaws in the dosing devices used in the presses.

The purpose of the present invention is to achieve a more rhythmic dosing of the material to be compressed and to work according to a predetermined program.

To accomplish the task, the dosing device in the press is made in the form of two channels communicating with a guide funnel of a cylindrical cavity equipped with a blade that oscillates around an axis by means of a gear mounted on it and coupled with a rail representing the servo cylinder, and is also used in the press a stroke counter, the pointer of which serves as a sensor, giving the command to automatically stop the press when it makes a set number of briquettes.

FIG. 1 shows a sectional view of the press; in fig. 2 shows a metering device, a general view.

The press is mounted on a base, which is a welded tank, which is a reservoir for the working fluid or oil, and is intended for installation on a line of metal-cutting machines, the chips from which enter the hopper, then the metering device.

The press is made with the upper position of the working cylinder 1 (Fig. 1) and multiplier 2, as well as the lower position of the funnel 3 of the loading mechanism and the movable press chamber 4. The press chamber is moved and the briquette is pushed out using a hydraulic cylinder 5, the piston rod of which by means of traverse 6 and t g 7 is rigidly connected to the press chamber.

No. 117636-2 -

In the initial position, the press chamber is lifted up and tightly pressed against the cone of the sleeve 8. The chips from the hopper fill the receiving funnel 9 (Fig. 2) of the metering device. From the funnel, the chips fall into the lower cylindrical part 10 of the device, which windows P and 12 communicate with the guide funnel 3.

In the cylindrical part there is a blade 13, which receives a swinging movement around the axis 14 by means of a pinion 15 sitting on it, coupled with a rack 16 representing the servo rod of the servo cylinder (not shown in the drawing).

From the funnel 3 (Fig. 1), the chip itself enters the sleeve 5 and the press chamber 4, the bottom of which is a fixed guide rod 17, rigidly connected to the frame 18. The working plunger 19 of the working cylinder / npji working stroke moves down, The pressing chips in the bale chamber 4, in which three pressing steps are sequentially activated.

At the end of pressing, the plunger goes up, the bale chamber is lowered down, releasing the cake 20 lying on the end portion of the fixed guide rod 17.

The press uses a conventional stroke counter (not shown in the drawing), the pointer of which serves as a sensor for issuing a command to automatically stop work when producing a specified number of briquettes.
