Technical Field

[0001] The invention relates to the technical field of seamless steel pipe processing, and in particular to an automatic lubrication mechanism for a seamless steel pipe cold drawing die and a use method thereof. Background Art

[0002] A steel pipe made of a whole piece of metal with no seams on the surface is called a seamless steel pipe. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, jacking pipes, etc. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

[0003] Before cold drawing, the surface of the seamless steel pipe must be treated to reduce friction during the cold deformation process. The commonly used treatment method is to coat the steel pipe surface with a steel pipe drawing lubricant. Currently, there are still some problems when coating the seamless steel pipe with a drawing lubricant: since it is inconvenient to rotate the seamless steel pipe, it is inconvenient to fully coat the seamless steel pipe, resulting in uneven coating. In addition, when the seamless steel pipe needs to be rotated, it is also manually rotated, which is time-consuming and laborious. For this reason, the present application proposes an automatic lubrication mechanism for a seamless steel pipe cold drawing die and a method for using the same. Summary of the invention

[0010] Preferably, a rectangular sleeve is fixedly connected to the mounting plate, a rectangular rod is slidably connected inside the rectangular sleeve, the arc plate is fixed to the upper end of the rectangular rod, a threaded groove is provided at the bottom of the rectangular rod, a second screw is threadedly connected in the threaded groove, a short rod is fixedly connected to the lower end of the second screw, the short rod is rotatably connected to the inner bottom of the rectangular sleeve, a transmission rod rotatably connected to the rectangular sleeve is penetrated by a transmission rod, a second bevel gear is fixed on the transmission rod and the round rod, the two second bevel gears are meshed with each other, and a handle is fixedly connected to the transmission rod.

[0011] Preferably, the oil spray lubrication mechanism comprises an oil tank fixed on a mounting plate, an oil pump is mounted on the oil tank, a shaped hose is mounted on the output end of the oil pump, a spray pipe is fixedly connected to the other end of the shaped hose, and a plurality of atomizing nozzles are mounted on the spray pipe.

[0012] The present invention also discloses a method for using the automatic lubrication mechanism of a seamless steel pipe cold drawing die, comprising the following steps: S1, put one end of the steel pipe on the outside of the four arc blocks and start the air pump, so that the moving rod, the arc blocks and the anti-skid pad can move, so that the anti-skid pad is against the inner wall of the steel pipe, so that the steel pipe can be positioned; S2, the handle is rotated, the rotation of the handle drives the transmission rod to rotate, the rotation of the transmission rod drives the second bevel gear to rotate, the round rod and the second screw can be rotated through the transmission of the second bevel gear, and the rectangular rod, the arc plate and the sponge pad can be moved up until the sponge pad is against the outer wall of the steel pipe; S3, start the second motor, the second motor drives the short rod and the first screw to rotate, because the guide block cannot rotate in the guide groove, the movement of the first screw can realize the movement of the guide block, and the movement of the guide block drives the installation plate and the arc plate to move, and the oil pump is started. The oil pump can transport the lubricating oil in the oil tank through the shaped hose to the spray pipe, and finally spray it through the atomizing nozzle and spray it onto the steel pipe; S4, the first motor drives the first bevel gear to rotate, and the rotation of the rotating tube can be realized by the transmission of the first bevel gear; thus, the sponge pad and the steel pipe rotate relative to each other, and the sponge pad can evenly spread the lubricating oil sprayed on the steel pipe; S5, after the coating is completed, the second solenoid valve is opened, and the air is discharged through the exhaust pipe. Under the action of the spring, the moving piston and the arc block are reset so that the steel pipe can be removed.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The air pump can deliver air to the installation box through the delivery pipe and the rotating pipe, and finally to the four piston cylinders. The increased air pressure in the piston cylinder can drive the moving piston to move, thereby realizing the movement of the moving rod, the arc block and the anti-skid pad, so that the anti-skid pad is against the inner wall of the steel pipe, so that the steel pipe can be positioned. This method can realize the positioning of steel pipes with different inner diameters.

[0014] 2. Manually turn the handle, the handle rotation drives the transmission rod to rotate, the transmission rod rotation drives the second bevel gear to rotate, the round rod and the second screw can be rotated through the transmission of the second bevel gear. Since the rectangular rod cannot rotate in the rectangular sleeve, the rotation of the second screw can realize the upward movement of the rectangular rod, the arc plate and the sponge pad until the sponge pad is against the outer wall of the steel pipe. The arc plate can be used to support the steel pipe, thereby ensuring its stable rotation.

[0015] 3. The second motor drives the short rod and the first screw to rotate. Since the guide block cannot rotate in the guide groove, the movement of the first screw can realize the movement of the guide block, and the movement of the guide block drives the installation plate and the arc plate to move. At the same time, the oil pump is started. The oil pump can transport the lubricating oil in the oil tank through the shaping hose to the spray pipe, and finally spray it through the atomizing nozzle and onto the steel pipe. The first motor drives the first bevel gear to rotate, and the transmission of the first bevel gear can realize the rotation of the rotating tube. In this way, the sponge pad and the steel pipe rotate relative to each other, and the sponge pad can evenly spread the lubricating oil sprayed on the steel pipe.

[0016] In summary, the present invention drives the positioned steel pipe to rotate through the first motor, and can evenly apply lubricating oil to the surface of the steel pipe, which saves time and effort, improves the efficiency of applying lubricating oil to the steel pipe, and can be applicable to various models of steel pipes.
