Abstract

The invention relates to the processing of metals by pressure, in particular to the structures of devices for the manufacture of parts such as glasses. The goal is to increase tool life by reducing the specific strain forces and expanding technological capabilities. The device comprises a container in the form of a high pressure unit with a cavity for the working fluid. The block is divided into two interconnected parts by the base plate, forming the upper and lower chambers. The lower punch is mounted in the upper chamber on the base plate with the possibility of movement along its axis towards the upper punch and provided with channels for the working fluid. The bottom chamber is equipped with a movable plunzhero.m. After the billet is fully pressed, the plunger stops and the lower punch under its own weight returns to its original position. All elements of the device are returned to their original position. 2 Il.

The invention relates to the processing of metals by pressure, in particular to devices for the manufacture of articles such as glasses.

The press press can develop a greater force than the top (Q2), i.e., chambers 4 and 5 create the pressure necessary to extract the extruded

The purpose of the invention is to increase the durability of the semifinished product when the tool ram moves upward by reducing the specificity, while the upper press slider through

the effort of deforming and expanding the tech-punch 1 creates the necessary counter-pressure by the force Qs. The high pressure fluid transmits a portion of the force developed by the lower cylinder of the press, non-liquid, the workpiece is extruded through the die. When this occurs, the workpiece is stretched. By the time of completion of the deformatological possibilities.

FIG. 1 shows the device in the extrusion stage of the workpiece, a general view;

in fig. 2 - the same, in the stage of extrusion, only to the blank, and partly through the key of the extruded glass. The lower punch. Under pressure

The device comprises an upper punch 1 mounted on the upper movable plate of the press, a high pressure block 2

with a cavity under the working fluid, the divisions (Fig. 2, right side) of the lower blade of the base plate 3 into two parts, the punch rests against the conical surface

forming the top 4 and bottom 5 ka-in the conical funnel of the matrix and ostamer. The upper chamber performs function, and the elongated blank of the matrix is stretched. On the base plate, the lower punch 6 is set to move under the action of a liquid, coaxially with the high-pressure matrix, while removing the punch. The lower chamber is locked with a movable 20 sone. After complete pressing of the workpiece by the plunger 7, the fastening of the shims on the movable plunger 7 stops and the lower

the punch 6 returns to its original position under its own weight, and the cycle is completed, all the elements of the device thus return to their original position.

The advantages of the device include the fact that the working fluid is practically not consumed, and with one pouring into the device it can be used many times, which allows a significant press or pusher. The lower and upper chambers communicate via channels 8 made in the lower punch and the base plate.

The device works as follows.

In the initial position, the upper punch 1 is in the extreme upper position, the lower punch 6 rests on the plate 3, and the plunger 7 is in the extreme upper CJllb iyi / IVV.

his position. The high pressure unit 2 is filled with liquid, the workpiece 9 is loaded and loaded with the punch 1. The mutual arrangement of the elements of the device before extrusion corresponds to FIG. 1 (left side). When loaded with force Q: Qi, it deforms, flows into the annular gap formed by the matrix and the lower punch, compressing the fluid in chambers 4 and 5 to a value determined by the force Qi

but simplify device automation. Invention Formula 35 A device for manufacturing parts such as glasses, comprising an upper punch, a container with a die and a lower punch, characterized in that, in order to increase tool durability by reducing specific deformation forces and expanding technological capabilities, the container is designed as a block in a customized press cylinder. The final pressure with the cavity under the working extrusion corresponds to the position of the liquid divided by the base plate on elements of the device shown in FIG. 1 (right side). The upper punch is in its lowest position, the lower punch is in the same position, and the backpressure plunger is in the lower position. At this point, the hydraulic system of the press switches. Now the bottom half45 two interconnected parts forming the upper and lower chambers, the lower punch is made with channels for the working fluid and installed in the upper chamber on the base plate with the possibility of movement along its axis towards the upper punch, and the lower chamber is equipped with a movable plunger. the lower cylinder of the press, directly to the workpiece, and part through the lower punch. Under pressure the liquid is pressed through the die. When this occurs, the workpiece is stretched. By the time of completion of the deformation (Fig. 2, right side), the lower punch rests against the conical surface but simplify device automation. Invention Formula Whose pressure with the cavity under the working fluid divided by the base plate on two interconnected parts forming the upper and lower chambers, the lower punch is made with channels for the working fluid and installed in the upper chamber on the base plate with the possibility of movement along its axis towards the upper punch, and the lower chamber is equipped with a movable plunger.
