Description

Technical Field

[0001] The present invention belongs to the field of press clutches, and particularly relates to an exhaust buffering and oil collecting device for the breathing port of a wet clutch of a press. Background Art

[0002] In the prior art, press clutches and brakes are used to start or stop the crank side rod mechanism of a press when the motor and the flywheel are rotating continuously. Therefore, the clutch and the brake are indispensable transmission components to ensure the normal operation of the press, and the two must work closely and coordinately. The inside of the wet clutch of the press is filled with hydraulic oil. When the clutch is working, gas will enter and exit the breathing port of the wet clutch in a breathing cycle alternately. The disadvantage is that during the process of the gas discharging from the breathing port, high-pressure air flow mixed with oil mist will be sprayed out from the breathing port, resulting in the oil mist spraying around and polluting the environment. Summary of the Invention

[0003] The purpose of the present invention is to provide an exhaust buffering and oil collecting device for the breathing port of a wet clutch of a press, which can achieve the effects of air flow buffering and oil mist collecting and refluxing by setting a pressure relief hole and an oil return hole for oil mist collecting and refluxing during the process of the gas discharging from the breathing port, and is applicable to the installation of various wet clutches.

[0004] The purpose of the present invention is achieved as follows: An exhaust buffering and oil collecting device for the breathing port of a wet clutch of a press includes a top cover and a tank base arranged corresponding to each other up and down. A circular tank body is vertically arranged between the top cover and the tank base. A balance air pressure pipe extending upward vertically is arranged on the top cover, and the balance air pressure pipe is communicated with the inside of the tank body. A central hole is penetrated through the middle of the tank base, and a vertical air outlet pipe is inserted into the central hole of the tank base from below. The lower end of the vertical exhaust pipe located inside the tank is inserted into the central hole of the tank base. The end of the air outlet pipe is fixed to the end of the exhaust pipe. A plug is arranged at the upper end of the exhaust pipe. A plurality of pressure relief holes are densely arranged on the outer periphery of the exhaust pipe above the central hole. A plurality of oil return holes are also arranged on the outer periphery of the exhaust pipe above the central hole. Each oil return hole is located below each pressure relief hole; A filter assembly is correspondingly arranged above the exhaust pipe inside the tank body.

[0005] When the present invention works, the gas discharged from the clutch breather port carries oil mist. The gas enters the exhaust pipe through the outlet pipe. The upper end of the exhaust pipe is blocked, and the gas is discharged laterally through the pressure relief holes on the outer periphery of the exhaust pipe. After the gas hits the inner side wall of the tank body, it is discharged upward. When the gas passes through the filter assembly, the oil mist can be blocked. Finally, the gas is discharged from the balance air pressure pipe to complete exhaust and pressure relief. The oil mist blocked by the filter screen of the filter assembly will flow downward, and the oil mist remaining on the inner side wall of the tank body also flows downward. When the clutch breather port inhales air, the oil mist is inhaled into the exhaust pipe through the return holes at the lower part of the exhaust pipe, and then the oil mist flows back into the clutch through the outlet pipe, which saves more hydraulic oil. Compared with the prior art, the beneficial effects of the present invention are as follows: The plug blocks the oil mist in the exhaust pipe, avoiding the direct upward spraying of the oil mist and causing the oil mist to splash everywhere; The oil mist condenses and converges in the tank body, on the upper filter screen and the lower filter screen of the filter assembly, and then flows into the buffer tank body, and then flows back into the wet clutch through the oil return hole again, avoiding the oil mist spraying everywhere and polluting the environment; During the process of the gas being discharged from the breather port, by setting the pressure relief holes and the oil return holes for oil mist collection and reflux, the effects of air flow buffering and oil mist collection and reflux are achieved, which is suitable for the installation of various wet clutches.

The outer diameter of the connecting part I is smaller than the outer diameter of the top cover. The inner wall of the upper end of the tank body is threadedly connected with the outer periphery of the connecting part I, and the upper end surface of the tank body abuts against the top cover.

[0007] As a further improvement of the present invention, both the top cover and the tank base are circular. The balance air pressure pipe is connected to the middle of the top cover, and the lower end of the balance air pressure pipe is inserted into the middle of the top cover.

[0008] In order to facilitate the connection between the tank body and the tank base, a connecting part II extending into the tank body is provided at the upper end of the tank base. The outer periphery of the connecting part II is circular, and the outer diameter of the connecting part II is smaller than the outer diameter of the tank base. The inner wall of the lower end of the tank body is threadedly connected with the outer periphery of the connecting part II, and the lower end surface of the tank body abuts against the tank base.

[0009] In order to facilitate the oil liquid flowing back from the inner wall of the tank body and the filter screen of the filter assembly into the oil return hole, the outlet pipe is fixed to the tank base, and the exhaust pipe is fixed to the tank base. A diversion groove is provided on the connecting part II of the tank base. The diversion groove is frustum-shaped, and the diversion groove coincides with the axes of the tank base, the exhaust pipe, and the outlet pipe.

The oil return hole is located above the inner wall of the lower end of the diversion groove, and the oil return hole is provided in the part of the exhaust pipe close to the central hole of the tank base. A circle of oil return holes is arranged around the outer periphery of the exhaust pipe.

[0010] In order to filter the oil flowing back into the oil return hole of the exhaust pipe and prevent impurities from flowing back into the clutch, an oil return filter screen is horizontally arranged inside the diversion groove. The outer periphery of the oil return filter screen is connected to the inner wall of the inclined side groove of the diversion groove. The oil return filter screen is located between the oil return hole and each pressure relief hole in the vertical direction, avoiding the direct backflow of oil without filtering impurities into the oil return hole.

[0011] As a further improvement of the present invention, the height position of the upper end of the exhaust pipe is at half of the height of the tank body. The inner diameter of the upper end of the diversion groove is equal to the inner diameter of the tank body, and the height of the diversion groove is one-third to one-half of the height of the exhaust pipe.

[0012] In order to facilitate the smooth dripping of oil from the upper filter screen downward into the bottom of the tank, the filtering assembly includes an upper filter screen and a lower filter screen. The outer peripheries of the upper filter screen and the lower filter screen are both connected to the inner wall of the tank body. The lower filter screen is arc-shaped, and the height of the outer periphery of the lower filter screen is lower than the height of the center. By setting two layers of filter screens, the effect of filtering oil mist is improved, and the downward dripping of oil from the arc-shaped lower filter screen is smoother and more convenient.
