Mechanical press brake automatic measuring and controlling lubrication device

Abstract

The invention relates to a mechanical press brake automatic measuring and controlling lubrication device. The mechanical press brake automatic measuring and controlling lubrication device comprises abrake, an oil mist feeding mechanism, a gas-inlet gas path, a gas-exhaust gas path, an oil mist concentration detection instrument and a PLC controller, wherein the oil mist feeding mechanism providesoil mist, one end of the gas-inlet gas path communicates with the oil mist feeding mechanism, the other end of the gas-inlet gas path communicates with a piston cavity, one end of the gas-exhaust gaspath communicates with the piston cavity, the other end of the gas-exhaust gas path communicates with the gas-exhaust end, and the oil mist concentration detection instrument is arranged between thegas-inlet gas path and an oil mist device and communicates with the PLC controller. An existing lubrication system adopts a design that gas inlet and gas exhaust share one passage, the situations of unsmooth oil mist circulation, low sealing ring oil mist concentration and inadequate lubrication are caused, by means of the mechanical press brake automatic measuring and controlling lubrication device, the traditional design is subverted, a gas-inlet gas path and gas-exhaust gas path non-coincidence technical structure is adopted, then in coordination with an intelligent detection and control technology, brake intelligent measuring and controlling lubrication is realized, the brake service life is prolonged, the product quality is improved, and the mechanical press brake automatic measuringand controlling lubrication device has the advantages of high reliability and green environmental protection.

Description

Technical field: [0001] The invention relates to the technical field of forging machine tools, in particular to an automatic measurement and control lubricating device for a mechanical press brake. Background technique: [0002] The brake is one of the main components of a mechanical press. At present, the interior of the existing brake mainly adopts a piston-type technical structure with a sealing ring, and the on-off action of the brake is controlled through the cooperation of air pressure, sealing ring, piston, spring and other components to realize the connection action of the entire transmission system. The brake and the clutch 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 brake is ventilated to drive the transmission...

AI Technical Summary

Problems solved by technology

[0005] In addition, there are still many deficiencies in the existing lubrication system. First, the concentration of oil mist in the oil mist cannot be monitored in real time, and the concentration of oil mist in the oil mist cannot be adjusted in real time according to the wear of the sealing ring to better lubricate the sealing ring. Monitor the operating status of the lubricator, and when the lubricator is blocked or damaged, as an ordinary operator, as there is no obvious external symptom, the maintenance of the lubricator on the upper part of the fuselage will be neglected until the brake sealing ring is severely worn It will only be discovered when there is an air leakage block accident and cannot continue to be used

The second is that the wear of the sealing ring cannot be monitored, and sometimes it can continue to be used with slight wear and air leakage, but the operator does not know when to replace it, so he can only judge based on experience, which increases the difficulty of technical diagnosis for the operator, and reduces production efficiency and product quality.

The third is that the lubricator adopts the form of an oil cup to store oil. The lubricator is installed on the top of the frame, which is inconvenient to observe at any time. The air entering the brake does not contain oil mist, which leads to the lack of oil in the sealing ring and aggravates the wear and tear

Fourth, when the brake is exhausted, the gas with oil mist is directly discharged into the outside air through the speed-regulating quick-discharge valve and the double solenoid valve, and oil dirt will form on the maintenance platform on the upper part of the frame for a long time, that is, pollute the environment and exist. Security risks

[0006] In summary, the existence of these problems restricts the widespread use of mechanical presses and the improvement of product quality, and cannot meet the reliability, intelligent measurement and control, and environmental protection needs of mechanical press automated production lines.
