Mechanical press clutch lubrication system

Abstract

The invention relates to a mechanical press clutch lubrication system. The mechanical press clutch lubrication system comprises a clutch, a lubricator supply mechanism, an air inlet air-channel and anexhaust air-channel, the lubricator supply mechanism provides lubricator; one end of the air inlet air-channel communicates with the lubricator supply mechanism, and the other end of the air inlet air-channel communicates with a piston cavity through a clutch shaft and a flywheel in sequence; one end of the exhaust air-channel communicates with the piston cavity, and the other end of the exhaustair-channel communicates with the exhaust end through the clutch shaft. The air inlet air-channel and the exhaust air-channel do not coincide. The situation that lubricator circulation is not smooth,lubricator concentration at a seal ring is low and the seal ring is still seriously worn due to the fact that a common channel design for air inlet and exhaust is adopted in an existing lubrication system exists, the traditional design is subverted, a non-coincident technical structure of the air inlet air-channel and the exhaust air-channel is adopted, lubricator circulation flow in a clutch cavity is achieved, the seal ring is effectively lubricated for a long time, and the wear of the seal ring is reduced. An intelligent detection means is adopted, intelligent measurement and control lubrication of the clutch seal ring is achieved, the service life of the clutch is prolonged, and high reliability and environmental protection are achieved.

Description

Technical field: [0001] The invention relates to the technical field of forging machine tools, in particular to a lubricating system for a mechanical press clutch. Background technique: [0002] The clutch is one of the main components of a mechanical press. At present, the interior of the existing clutch mainly adopts a piston-type technical structure with a sealing ring. Through the cooperation of air pressure, sealing ring, piston, spring and other components, the on-off action of the clutch is controlled to realize the connection action of the entire transmission system. The clutch and the brake adopt the pneumatic interlocking control method. When the press stroke is opened, the electromagnetic double valve and the two-position three-way electromagnetic valve act simultaneously, and the compressed air quickly enters the brake through the double valve to disengage the brake disc, and then the clutch is ventilated to drive the transmission. When the mechanism is running ...

AI Technical Summary

Problems solved by technology

[0003] When the mechanical press and the automatic feeding of the robot are operated in a single stroke state, the clutch needs to be frequently engaged and disengaged. With long-term and high-frequency operation, the sealing ring on the clutch piston will wear out rapidly due to lack of lubricating oil. When the wear reaches a certain level, air leakage will occur, causing the clutch torque to decrease, causing the clutch of the mechanical press to slip, resulting in insufficient punching force of the slider and resulting in waste products, and it is also difficult to reset the slider after the clutch slips

[0004] In order to improve the lubrication of the clutch piston seal ring, attempts have been made in the prior art, and the currently generally adopted scheme includes a pressure tank, a lubricator and a passage for lubricating the piston seal ring, which simultaneously serves as the intake passage and exhaust passage of the clutch. The air channel, that is, the air intake and exhaust share the same channel. Although the above solution improves the lubrication effect to a certain extent, the lubrication effect is not good

The root cause of the poor lubricating effect of the above scheme is that the air intake and the air outlet share the same channel, and the gas with a high concentration of oil mist pushes the gas with a low oil mist concentration inside the channel to move forward during the intake, which will cause Dispersion of the oil mist; when the gas returns to the original path when exhausting, the gas with a high concentration of oil mist will be discharged first, which will cause the oil mist to not circulate effectively in the clutch cavity, and the oil mist will not circulate smoothly for a long time , it will cause low oil mist concentration at the sealing ring inside the clutch, and insufficient lubrication at the sealing ring, which will aggravate the wear of the sealing ring, which will seriously affect the working effect and service life of the clutch, and reduce the accuracy and stability of the machine tool
