Description
Technical Field
[0001] This utility model relates to the field of processing equipment technology, specifically to a high-strength cold-rolled steel pipe processing equipment. Background Technology
[0002] High-strength cold-rolled steel pipe is a type of steel pipe produced through cold rolling. It has advantages such as high precision, high strength, good surface finish, and a wide range of sizes. During the rolling process, the cooling device cools the steel to improve its hardness and strength. At the same time, the lubrication system lubricates the rolls and the steel to reduce friction and wear. After cold rolling, the pipe is arranged, cut, and sorted by the pipe removal unit to meet certain size and shape requirements.
[0003] The existing technology has the following problems:
[0004] The existing equipment does not provide lubrication and cooling for the steel pipe during operation. During cold rolling, the temperature of the workpiece and rolls will rise significantly due to severe deformation and friction. Without lubricating coolant to effectively reduce these temperatures, it may lead to a decline in material properties or equipment damage. The lack of lubricating coolant will cause more intense direct contact between the steel surface and the rolls, thereby increasing surface roughness and even causing defects such as scratches and cracks. Furthermore, the existing equipment does not limit and fix the steel pipe. Without limit and fixation, the steel pipe is prone to displacement or deviation during processing, resulting in a decrease in processing accuracy. Especially in the cutting process, even a slight movement of the steel pipe may cause the finished product dimensions to not meet the requirements. Utility Model Content

Then the steel pipe 6 is limited and fixed, and then the steel pipe 6 can be rolled. At the same time as rolling, the pump 10 can be turned on to spray the cooling lubricant inside the storage tank 3 onto the steel pipe 6.
[0024] like Figure 2 As shown, this utility model provides a technical solution: Preferably, a movable frame 11 is slidably connected to the lower inner wall of the fixed box 2, a first motor 12 is fixedly connected to the left side of the movable frame 11, a rotating shaft 13 is fixedly connected to the left side of the toothed column 9, a pressure roller 14 is fixedly connected to the outer wall of the rotating shaft 13, the left end of the upper rotating shaft 13 is fixedly connected to the output end of the first motor 12, a steel pipe 6 is movably connected to the outer wall of the pressure roller 14, a liquid pump 10 is fixedly connected to the left side of the fixed box 2, the output end of the liquid pump 10 is fixedly connected to the spray pipe 7, and the output of the liquid pump 10...

The first motor 12 can drive the rotating shaft 13 to rotate, which in turn drives the toothed column 9 to rotate. The interaction between the toothed column 9 and the rack can drive the moving frame 11 to move as a whole. During the movement of the moving frame 11, the lower toothed column 9 will mesh with the rack, driving the lower toothed column 9 to rotate, so that the two rotating shafts 13 rotate simultaneously. The rotation of the rotating shafts 13 can drive the pressure roller 14 to rotate, rolling the steel pipe 6.
[0025] like Figure 3-4As shown, this utility model provides a technical solution: Preferably, the limiting device 5 includes a fixing block 51, a second motor 52 is fixedly connected to the front side of the fixing block 51, a threaded rod 53 is fixedly connected to the output end of the second motor 52, a movable frame 55 is threadedly connected to the outer wall of the threaded rod 53, a connecting rod 54 is fixedly connected to the front side of the inner wall of the fixing block 51, two inclined grooves 56 are opened through the left and right sides of the movable frame 55, the outer wall of the connecting rod 54 is slidably connected to the movable frame 55, two support plates 57 are fixedly connected to the rear side of the inner wall of the fixing block 51, a sliding groove 58 is opened through the left side of the support plate 57, a limiting post 59 is slidably connected to the inner surface of the inclined groove 56, the outer wall of the limiting post 59 is slidably connected to the sliding groove 58, and the opposite surfaces of the two limiting posts 59 are fixed. A clamping block 510 is connected to the outer wall of the steel pipe 6. When the steel pipe 6 is fixed in a limited position, the second motor 52 can be started. The second motor 52 can drive the threaded rod 53 to rotate. The rotation of the threaded rod 53 can drive the moving frame 55 to move on the connecting rod 54. The movement of the moving frame 55 can drive the inclined groove 56 to move. The cooperation between the inclined groove 56 and the limiting post 59 can drive the two limiting posts 59 to move in opposite or the same direction at the same time. When the two limiting posts 59 move in the same direction on the inner surface of the sliding groove 58, the two clamping blocks 510 can be driven to move towards the middle to press and limit the steel pipe 6. This can ensure that the steel pipe 6 maintains an accurate position during processing, which is convenient for subsequent cutting processing.
[0026] like Figure 5 As shown, this utility model provides a technical solution: Preferably, a connecting pipe 17 is fixedly connected to the upper side of the liquid storage tank 3, and the outer wall of the connecting pipe 17 is fixedly connected to the fixed box 2.

Then, the fan 19 is turned on, and the fan 19 can draw outside air into the lower interior of the reservoir 3 through the input pipe. The air will then carry the heat from the lower part of the reservoir 3 out of the device, thereby achieving cooling. In addition, the device can also recycle the lubricant and coolant, reducing production costs.
[0027] The working principle of this high-strength cold-rolled steel pipe processing device will be explained in detail below.
[0028] like Figure 1-5As shown, during the use of the device, cooling lubricant can first be injected into the storage tank 3 through the liquid filling pipe 4.

When the steel pipe 6 is limited and fixed, the second motor 52 can be started. The second motor 52 can drive the threaded rod 53 to rotate. The rotation of the threaded rod 53 can drive the moving frame 55 to move on the connecting rod 54. The movement of the moving frame 55 can drive the inclined groove 56 to move. The cooperation between the inclined groove 56 and the limiting post 59 can simultaneously drive the two limiting posts 59 to move in opposite or the same direction. When the two limiting posts 59 move in the same direction on the inner surface of the sliding groove 58, the two clamping blocks 510 can be driven to move towards the middle to press and limit the steel pipe 6. This can ensure that the steel pipe 6 maintains an accurate position during processing, which is convenient for subsequent cutting processing. After that, the steel pipe 6 can be rolled. During the rolling process, the first motor 12 can be started. The first motor 12 can drive the rotating shaft 13 to rotate, thereby... The toothed column 9 rotates, and the interaction between the toothed column 9 and the rack drives the entire moving frame 11 to move. During the movement of the moving frame 11, the lower toothed column 9 meshes with the rack, causing the lower toothed column 9 to rotate, thereby causing the two rotating shafts 13 to rotate simultaneously. The rotation of the rotating shafts 13 drives the pressure roller 14 to rotate, rolling the steel pipe 6. At the same time as rolling, the liquid pump 10 can be turned on to spray the cooling lubricant inside the liquid storage tank 3 onto the steel pipe 6. After the cooling lubricant is used up, After use, the coolant enters the reservoir 3 through the connecting pipe 17, and then passes through multiple heat-conducting plates 18 via the metal heat-conducting pipe 15. The metal heat-conducting pipe 15 transfers the heat of the used coolant to the heat-conducting plates 18. Then, the fan 19 is turned on, and the fan 19 draws outside air into the lower part of the reservoir 3 through the input pipe. The air then carries the heat from the lower part of the reservoir 3 out of the device, thereby achieving cooling. In addition, the device can also recycle the coolant, reducing production costs.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
