At present, the lubrication of copper nuts and screws of a screw press adopts oil immersion type lubrication, the screws and the copper nuts are immersed in lubricating oil, a cross beam of a machine body is a large oil tank, each device needs about 1000 kilograms of high-strength lubricating oil on average, the energy consumption is high, the lubricating oil can deteriorate after being stored in the device for a long time, and a sealing ring is immersed in the oil for a long time to age to generate oil leakage and seriously pollute the environment.
Disclosure of Invention
The invention aims to provide a copper nut forced lubricating device of a heavy numerical control screw press, which has the advantages of forced lubrication, oil floating effect, sufficient lubrication of a screw pair, good lubricating effect and long service life.
In order to achieve the purpose, the heavy numerical control screw press copper nut forced lubrication device comprises a machine body cross beam, copper nuts fixedly arranged in a machine body cross beam hole, a pneumatic pump arranged on the machine body and providing lubricating oil power, a forced oil distributor arranged on the machine body and connected with the pneumatic pump through a lubricating pipeline, a plurality of forced lubrication points which penetrate through the machine body cross beam and a copper nut spiral tooth surface and distribute the lubricating oil to each branch through the forced oil distributor, wherein the forced lubrication points are provided with forced lubrication horizontal holes on the copper nuts, the copper nut tooth surface is provided with semicircular grooves and semicircular groove type inclined lubrication holes communicated with the tail ends of the forced lubrication horizontal holes, and ports are arranged at the threads of the copper nuts; when the press works, the screw rod is connected with the screw pair tooth surface of the copper nut, and the port is arranged from the beginning to the end of the thread of the copper nut, so that the lubricating spiral oil way forms a closed working environment.
The invention relates to a copper nut forced lubrication device of a heavy numerical control screw press, which is characterized in that ports are arranged at the joint of screw threads of two workpieces, namely a screw rod and a copper nut, from the beginning to the end of the screw thread of the copper nut when the press works, so that a lubricating spiral oil way forms a closed working environment. The pneumatic pump is used for providing power, the forced oil separator divides the lubricating oil to each forced lubricating point, the copper nut outer diameter closed circular ring path is filled with the modulated mixed lubricating oil, the forced lubricating hole from the copper nut to the tooth surface is filled with the rotating thread semicircular groove, and under a general state, the lubricating oil can also play an oil floating role, so that the weight of a moving part is relatively reduced.
According to the copper nut forced lubricating device of the heavy numerical control screw press, the semicircular groove can store lubricating oil, so that an oil floating effect is achieved, the screw pair is sufficiently lubricated, the lubricating effect is good, and the service life is long.
The invention relates to a copper nut forced lubricating device of a heavy numerical control screw press, which has the working principle that: when the device runs, the screw moves downwards, the lower tooth surface of the screw and the upper tooth surface of the copper nut are always in contact with lubricating oil and cannot seep out, but when the device is hit, gaps are formed between the two tooth surfaces instantly, and the lubricating oil can be sprayed to the whole contact tooth surface by using the pressure in a forced lubricating system, so that the lubricating effect can be achieved. The lubricating oil at the bottom of the copper nut is included, so that the whole tooth surface of the copper nut is filled with the lubricating oil, and the screw and the copper nut can be fully lubricated.
In conclusion, the copper nut forced lubricating device for the heavy numerical control screw press has the advantages of forced lubrication, oil floating effect, full lubrication of a screw pair, good lubricating effect and long service life.
