Description

Technical Field

[0001] This utility model relates to the technical field of bearing steel pipe processing equipment, specifically to a friction-reducing lubrication device for cold drawing of bearing steel pipes. Background Technology

[0002] In the cold drawing process of bearing steel tubes, friction-reducing lubrication is crucial. Good friction-reducing lubrication can reduce the friction between the steel tube and the die, reduce energy consumption, improve the surface quality of the steel tube, and extend the service life of the die.

[0003] Traditional friction-reducing lubrication methods have many shortcomings, such as uneven lubrication, which leads to inconsistent friction in different parts of the steel pipe, affecting the dimensional accuracy and surface roughness of the steel pipe; the amount of lubricating medium applied is difficult to control precisely, too much will cause waste and pollute the environment, while too little will not achieve a good friction-reducing effect; in addition, when the cold drawing process is ongoing, the lubricating medium cannot be replenished in time, resulting in a gradual decrease in the lubrication effect. Therefore, there is an urgent need for a new type of friction-reducing lubrication device for cold drawing of bearing steel pipes to solve these problems. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned lubrication devices, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a friction-reducing lubrication device for cold-drawing bearing steel pipes, which solves the problem of uneven lubrication.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A friction-reducing lubrication device for cold-drawn bearing steel pipes includes a base, a plurality of support plates fixedly mounted on the top of the base, a rotating shaft rotatably mounted inside the support plates, a rotating roller fixedly mounted on the wall of the rotating shaft, a plurality of protrusions fixedly mounted on the wall of the rotating roller, a motor fixedly mounted on one side of the support plates, the output end of the motor fixedly connected to one of the rotating shafts, a rotating wheel fixedly mounted on one end of the rotating shaft, a belt fitted against the outer wall of the rotating wheel, a lubrication box fixedly mounted on the top of the support plates, an oil distribution plate fixedly mounted on the bottom of the lubrication box, a plurality of oil distribution ports fixedly mounted on the bottom of the oil distribution plate, a replenishment tank fixedly mounted on the top of the lubrication box, a connecting pipe fixedly mounted on the bottom of the replenishment tank, one end of the connecting pipe fixedly connected to the lubrication box, and a one-way valve fixedly mounted on the wall of the connecting pipe.

[0008] Preferably, the lubrication tank outlet is fixedly equipped with a flow control mechanism, which includes a flow control valve and a flow meter.

[0009] Preferably, a liquid level sensor is fixedly installed inside the replenishment tank, and an alarm is fixedly installed at the bottom of the liquid level sensor.

[0010] Preferably, one of the support plates is fixedly provided with an external power source on one side.

[0011] Furthermore, an oil inlet is fixedly provided on the top of the replenishment tank.

[0012] Preferably, a support column is fixedly provided at the bottom of the base.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] This invention utilizes raised points on the rotating rollers for lubrication, ensuring uniform lubrication. The design of the rotating roller assembly, especially the tiny raised points on the roller surface, allows the lubricating medium to adhere evenly to the surface of the bearing steel pipe, effectively reducing frictional differences between different parts of the pipe and improving dimensional accuracy and surface quality. Precise control of the application amount is achieved through the flow control valve and flow meter working in conjunction with the flow control mechanism, which precisely controls the flow rate of the lubricating medium according to actual processing needs, avoiding waste and insufficiency of the lubricating medium while also reducing environmental pollution. Timely replenishment of the lubricating medium is ensured by the level sensor and alarm in the replenishment mechanism, which monitors the lubricating medium level in the replenishment tank in real time. When the level is too low, it promptly reminds the operator to replenish the lubricating medium, guaranteeing the continuous and stable operation of the lubrication device during cold drawing and improving processing efficiency.
