[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A surface treatment structure for a cold-rolled seamless tube mandrel includes a cleaning component 1, a lubrication component 2, a mandrel body 3, a base 4, and a cold rolling mill body 5. The cleaning component 1 is disposed on the top of the base 4, the lubrication component 2 is disposed on the top of the cleaning component 1, the mandrel body 3 is fixedly connected to the front side of the cold rolling mill body 5, and the cold rolling mill body 5 is fixedly connected to the top of the base 4.

[0027] The cleaning assembly 1 includes a cleaning wheel 101, a first fixing pin 102, a first connecting seat 103, and a first electric telescopic rod 104. The cleaning wheel 101 is rotatably connected to the surface of the first fixing pin 102. The first fixing pin 102 is bolted to the inside of the first connecting seat 103. The first connecting seat 103 is fixedly connected to the top of the first electric telescopic rod 104. The first electric telescopic rod 104 is fixedly connected to the bottom of the base 4.

[0028] In this embodiment: the cleaning component 1, used in conjunction with the lubrication component 2, can clamp the mandrel body 3 and clean debris from its surface during rotation. The lubrication component 2, used in conjunction with the threaded grooves on the surface of the mandrel body 3, can provide uniform lubrication.

The first fixing pin 102 can fix the connection between the cleaning wheel 101 and the first connecting seat 103. The first electric telescopic rod 104 can adjust the connection of the first connecting seat 103.

[0029] Specifically, such as Figure 4 As shown, the lubrication assembly 2 includes a support frame 201, which is fixedly connected to the top of the base 4. A second electric telescopic rod 202 is fixedly connected to the top of the support frame 201, and an oil tank 203 is fixedly connected to the bottom of the second electric telescopic rod 202.

[0030] Specifically, such as Figure 4 As shown, an oil injection pipe 204 is fixedly connected to the bottom of the oil tank 203, and an electric valve 205 is fixedly connected to the surface of the oil injection pipe 204.

[0031] Specifically, such as Figure 4 As shown, the second connecting seat 206 is slidably connected to both sides inside the support frame 201. The top of the second connecting seat 206 is fixedly connected to the bottom of the oil tank 203. The second fixing pin 207 is bolted inside the second connecting seat 206. The oiling wheel 208 is rotatably connected to the surface of the second fixing pin 207.

[0032] In this embodiment: the support frame 201 connects to the second electric telescopic rod 202, which in turn connects to and adjusts the oil tank 203. The oil tank 203 stores lubricating oil. The oil injection pipe 204 delivers lubricating oil to the surface of the oiling wheel 208. The electric valve 205, an existing intelligent control valve, controls the opening and closing of the oil injection pipe 204. The second connecting seat 206, used in conjunction with the second fixing pin 207, connects to the oiling wheel 208. The oiling wheel 208 applies lubricating oil to the surface of the mandrel body 3 for lubrication.

[0033] Specifically, such as Figure 4 As shown, an oil filling hole 6 is provided on the front side of the oil tank 203, and a sealing cap 7 is attached to the inner wall of the oil filling hole 6.

[0034] Specifically, such as Figure 5 As shown, the support frame 201 has sliding grooves 8 on both sides inside, and the inner wall of the sliding grooves 8 is slidably connected to the sides of the first connecting seat 103 and the second connecting seat 206.

[0035] In this embodiment: by setting the oil injection hole 6, the oil injection hole 6 can achieve the effect of injecting lubricating oil into the oil tank 203; by setting the sealing cover 7, the sealing cover 7 can achieve the effect of sealing the oil injection hole 6; by setting the sliding groove 8, the sliding groove 8 can achieve the effect of limiting the sliding connection between the first connecting seat 103 and the second connecting seat 206.

[0036] Specifically, such as Figure 5 As shown, a first connecting hole 9 is provided at the bottom of the base 4, and the inner wall of the first connecting hole 9 is slidably connected to the surface of the first electric telescopic rod 104.

[0037] Specifically, such as Figure 5 As shown, a second connecting hole 10 is provided on the top of the support frame 201, and the inner wall of the second connecting hole 10 is slidably connected to the surface of the second electric telescopic rod 202.

[0038] In this embodiment: by setting the first connecting hole 9, the first connecting hole 9 can achieve the effect of providing connection conditions between the first electric telescopic rod 104 and the first connecting seat 103. By setting the second connecting hole 10, the second connecting hole 10 can achieve the effect of providing connection conditions between the second electric telescopic rod 202 and the second connecting seat 206.

[0039] Working principle: First, open the sealing cover 7, then inject lubricating oil into the oil tank 203 through the oil injection hole 6. Then, open the first electric telescopic rod 104, which raises and lowers the first connecting seat 103, causing the top of the cleaning wheel 101 to contact the bottom of the mandrel body 3. At the same time, the threaded protrusion on the surface of the cleaning wheel 101 engages with the threaded groove on the surface of the mandrel body 3. Then, open the second electric telescopic rod 202 to adjust the oil tank 203, which in turn drives the second connecting seat 206 to adjust the oiling wheel 208, causing the bottom of the oiling wheel 208 to contact the top of the mandrel body 3. The mandrel body 3 engages with the threaded groove on its surface. During use, the electric valve 205 can be opened to open the oil injection pipe 204, allowing lubricating oil to flow through the oil injection pipe 204 onto the surface of the oiling wheel 208. The mandrel body 3 rotates back and forth during operation, thus performing cold rolling on the steel pipe. When the mandrel moves back and forth in coordination with the rotation, it drives the oiling wheel 208 to rotate, allowing the lubricating oil to be evenly applied to the surface of the mandrel body 3, thereby lubricating the mandrel body 3. At the same time, when the mandrel is retrieved, the cleaning wheel 101 at the bottom removes debris from its surface.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
