Abstract

Usage: supply of atomized lubricant to lubricated surfaces. Summary of the invention; the device comprises a housing with a nozzle and a spray chamber, a lubricant reservoir. A sleeve with a hole in the bottom is mounted in the housing, the cavity of which is connected to a source of compressed air. The sleeve and body are displaced relative to each other in a plane perpendicular to the axis of the nozzle and the hole of the sleeve. 3 ill.

Description

The invention relates to auxiliary equipment for forging and pressing and can be used to supply liquid process lubricant and a cavity of dies.

An object of the invention is to simplify the design of a lubricant supply device.

The displacement of the housing and the sleeve relative to each other makes it possible to use the mismatch between the axes of the nozzle and the hole as a mechanical barrier to the flow, and thus the curvature of the flow path from the hole in the sleeve to the spray chamber. At the same time, the operating mode of the device changes: from the suction mode due to the discharge that occurs when the axes of the nozzle and the bore of the sleeve coincide, and the lubricant is supplied to the purge and sparging mode due to the pressure in the rarefaction chamber above atmospheric when the axis of the nozzle and the bore of the sleeve do not coincide.

The location in the device’s body, for example, of four nozzles movable relative to the respective spray chambers, makes it possible to supply dies to four surfaces (two upper and two lower) during on-off stamping, and to control the device using one actuator,

The intensity of the interrelated purging of the supply channels and the nozzle and sparging of the lubricant in the tank is controlled by the relative displacement — the axes of the nozzle and the sleeve bore in the direction perpendicular to their axes.

In FIG. 1 is a perspective view of a lubricant supply device; FIG. 2 is a view along arrow A in FIG. 1, FIG. 3 is an arrangement of four nozzles in one housing.

2 with an opening 3 in the bottom part coaxial with the spray chamber A, the sleeve 2 was fixed from axial movement by a pin 5, rigidly fastened to the sleeve and located in the groove of the housing 1, closed by a cover 6. The opening of the hole 3 relative to the spray chamber 4 is made using pin 5, relative to the housing 1, for example, by an electromagnet (not shown in FIG.). Air is supplied through the nozzle 7 and the nut 8, the lubricant is sucked during operation of the device through the nozzle 9. A nozzle is mounted at the outlet of the spray chamber from the housing (not shown).

The device operates as follows.

The air flow from the pneumatic network through the nozzle 7, the passage through the hole 3 and the spray chamber 4 adjacent to it, in the device body 1, creates a vacuum in the area of which the end face of the nozzle 9. is connected to the lubricated reservoir (not shown in the drawing). Through the nozzle 9, the lubricant is sucked into the cavity of the housing 1 and sprayed in the chamber 4. With the pin 5, rigidly fastened to the sleeve 2, the hole 3 is displaced relative to the axis of the spray chamber 4 in the plane perpendicular to the axis of the hole 3 and chamber 4. and air the flow from the opening 3 swirls from the abutment against the wall of the internal cavity of the housing 1. In this case, a pressure above atmospheric pressure is created in the discharge zone and the device switches over to the purge and sparge mode. Return sleeve 2

with the hole 3 in the position where the hole 3 becomes coaxial with the spray chamber 4, it switches to the spray lubricant supply mode.

In FIG. Figure 3 shows an arrangement of four holes 3 and four spray chambers 4 in a housing 1 for lubricating the two upper and two lower die cavities during double-punching, for example, in a roughing and finishing pen. The four sprayed lubricant streams are controlled by a pin 5 by a single actuator, while the dimensions of the installation are significantly reduced.
