Technical Field

[0001] The utility model relates to the technical field of steel pipe rolling, and particularly relates to a cold rolling device for stainless steel seamless steel pipes for fluid transportation. Background Technique

[0002] Stainless steel seamless steel pipe is a long steel with a hollow cross-section and no seams around. Due to its excellent corrosion resistance, good sealing performance, high hardness and strength, and smooth surface, it is very suitable for transporting various liquid media, so it is widely used in chemical industry, petroleum, electric power, metallurgy and other fields. In the production process of stainless steel seamless steel pipes, cold rolling is generally used to process the steel pipe blank into a seamless pipe with a certain diameter and wall thickness, with high efficiency and is currently widely used.

[0003] When cold rolling steel pipes currently, generally, a conveying mechanism first clamps the steel pipe and moves it forward to send the pipe material into the cold rolling mill for processing. The steel pipe is compressed and stretched by the rollers in the cold rolling mill, thereby changing the diameter of the steel pipe. However, there is generally some oil stain remaining on the outer surface of the steel pipe blank. When clamping the steel pipe and driving it to move, it is easy to have sliding between the steel pipe and the fixing part, thus affecting the conveying effect. To solve this technical problem, the utility model proposes a cold rolling device for stainless steel seamless steel pipes for fluid transportation. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a cold rolling device for stainless steel seamless steel pipes for fluid transportation, which can effectively solve the problems mentioned in the background technique.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0023] As Figures 1-5 shown, a cold rolling device for stainless steel seamless steel pipes for fluid transportation includes a bottom plate 1. An extrusion mechanism 2 is arranged on the upper surface of the bottom plate 1. A conveying mechanism 3 is arranged on one side of the bottom plate 1 where the extrusion mechanism 2 is located. The extrusion mechanism 2 includes a sliding box 201. The lower part of the sliding box 201 is slidably connected to the bottom plate 1. Two limiting grooves are arranged on the bottom plate 1. The sliding box 201 is provided with limiting components at the positions of the limiting grooves to prevent the sliding box 201 from shifting during movement and improve stability. The limiting grooves and limiting components can also be replaced with a guide rail and roller structure to reduce the friction between the sliding box 201 and the bottom plate 1. A hydraulic rod 202 is installed on the inner wall of the sliding box 201. An extrusion plate 203 is installed at the telescopic end of the hydraulic rod 202. The inner side of the extrusion plate 203 is provided with a rough surface to increase the friction with the steel pipe.

[0024] The conveying mechanism 3 includes a fixing plate 301. The lower surface of the fixing plate 301 is fixedly connected to the bottom plate 1. A chute 302 is provided on the inner wall of the fixing plate 301. A motor 303 is installed on the outer surface of the sliding box 201. A rotating rod 304 is fixedly installed at the output end of the motor 303. The outer surface of the rotating rod 304 is slidably connected to the chute 302. A toothed ring 305 is fixedly installed at the end of the rotating rod 304. A toothed plate 306 is meshed with the outer surface of the toothed ring 305. One side surface of the toothed plate 306 is fixedly connected to the bottom plate 1. When the motor 303 operates, it will drive the toothed ring 305 to rotate. Through the cooperation of the toothed plate 306 and the toothed ring 305, the horizontal movement of the toothed ring 305 is realized. The toothed ring 305 drives the sliding box 201 to move through the motor 303.

[0025] On one side of the extrusion mechanism 2, there is a cold rolling mill body 4. The steel pipe is conveyed into the inside of the cold rolling mill body 4 for cold rolling. A blower 5 is installed on the other side of the bottom plate 1 where the extrusion mechanism 2 is located. A liquid storage tank 6 is provided on the side of the blower 5 away from the extrusion mechanism 2. The outer surface of the liquid storage tank 6 is fixedly connected to the bottom plate 1. A liquid spraying ring 7 is fixedly installed on the inner wall of the liquid storage tank 6. The diameter of the liquid spraying ring 7 is larger than that of the steel pipe. The steel pipe is sleeved therein. A plurality of liquid spraying holes are provided on the inner side of the liquid spraying ring 7, and high-pressure liquid can be sprayed out.

[0026] On one side of the liquid storage tank 6, there is a circulation mechanism 8. The circulation mechanism 8 includes a liquid storage barrel 801. A water outlet pipe with a valve is provided at the bottom of the liquid storage barrel 801. A feed inlet is provided at the upper part of the liquid storage barrel 801. A water pump 802 is installed at the upper part of the liquid storage barrel 801. An input end of the water pump 802 is provided with a pipe connected to the bottom of the liquid storage barrel 801. An outlet pipe 803 is installed at the output end of the water pump 802. The outer surface of the outlet pipe 803 penetrates through the liquid storage tank 6 and is fixedly connected to the liquid spraying ring 7. The water pump 802 can inject the cleaning liquid inside the liquid storage barrel 801 into the inside of the liquid spraying ring 7, and at the same time pressurize the cleaning liquid so that it forms a high-pressure water column and sprays out from the inner side of the liquid spraying ring 7.

[0027] A connecting pipe 804 is connected to the bottom of the liquid storage barrel 801. One end of the connecting pipe 804 away from the liquid storage barrel 801 is connected to the liquid storage tank 6. The connecting pipe 804 connects the liquid storage barrel 801 and the liquid storage tank 6. Two sealing rings 9 are installed on the outer surface of the liquid storage tank 6. The two sealing rings 9 block both sides of the liquid storage tank 6 to prevent the cleaning liquid from leaking out inside the liquid storage tank 6. One of the sealing rings 9 is detachably connected to a water-absorbing sponge 10. The water-absorbing sponge 10 can be connected to one side of the sealing ring 9 by means of clamping or threaded connection, etc. When needed, the water-absorbing sponge 10 can be replaced to prevent its excessive water absorption from affecting the water absorption effect.

[0028] It should be noted that during the actual use of this device, the steel pipe is successively passed through the liquid storage tank 6 and the extrusion mechanism 2. The motor 303 rotates to drive the toothed ring 305 to rotate. Through the cooperation of the toothed plate 306 and the toothed ring 305, the horizontal movement of the toothed ring 305 is realized. The toothed ring 305 drives the sliding box 201 to move through the motor 303. When the sliding box 201 moves to a position away from the cold rolling mill body 4, the hydraulic rod 202 extends to drive the extrusion plate 203 to squeeze the steel pipe, thereby fixing the steel pipe inside the sliding box 201. Then the motor 303 rotates in the reverse direction, so that the sliding box 201 moves closer to the cold rolling mill body 4. Then, the extrusion plate 203 moves away from the steel pipe, and this process is repeated successively, thereby realizing the pushing of the steel pipe and achieving the effect of conveying the steel pipe.

[0029] During the process of conveying the steel pipe, the water pump 802 pumps the cleaning liquid inside the liquid storage barrel 801, and injects the cleaning liquid into the inside of the spraying ring 7 through the liquid outlet pipe 803. The spraying ring 7 flushes the outer surface of the steel pipe, thereby removing substances such as oil stains on the outer surface of the steel pipe and achieving the effect of removing oil stains on the outer surface of the steel pipe. The steel pipe continues to move forward. The cleaning liquid on the outer surface of the steel pipe is blocked by the sealing ring 9 and remains inside the liquid storage tank 6 to prevent the cleaning liquid from leaking. The outer surface of the steel pipe then passes through the water-absorbing sponge 10, and the water-absorbing sponge 10 absorbs the cleaning liquid and other substances on the outer surface of the steel pipe, thereby further removing the liquid on the outer surface of the steel pipe. Then, the blower 5 blows air on the outer surface of the steel pipe to dry it, thereby increasing the friction on the outer surface of the steel pipe to prevent the outer surface of the steel pipe from slipping with the extrusion plate 203.

[0030] The cleaning liquid after flushing falls to the bottom of the liquid storage tank 6. The liquid storage barrel 801 and the liquid storage tank 6 are connected by the connecting pipe 804, so that the cleaning liquid inside the liquid storage tank 6 enters the inside of the liquid storage barrel 801, thereby realizing the recycling of the cleaning liquid and reducing costs. After recycling multiple times, the valve at the bottom of the liquid storage barrel 801 can be opened to discharge the cleaning liquid, and then clean cleaning liquid is injected from the feed port at the top of the liquid storage barrel 801, achieving the effect of facilitating the replacement of the cleaning liquid.
