Embodiment 1

[0028] In order to overcome the problem in the prior art that the pipe is easily deformed by the high temperature of cold rolling during the transfer process after cold rolling in the cold rolling mill, the present invention provides such as figure 1 As shown in the discharge air cooling device for a cold rolling mill, the invention can rapidly reduce the temperature of the tubes output from the cold rolling mill, prevent the tubes from being deformed during transportation after cold rolling, and improve the performance of the cold rolled tubes. At the same time, the device also has the function of self-cleaning of lubricating oil on the surface of the pipe, which does not require manual operation and reduces the labor intensity of the staff.

[0029] like figure 1 and figure 2 As shown, a discharge air cooling device for a cold rolling mill includes a mounting plate 1, a cooling cylinder 2 is fixedly connected to the upper surface of the mounting plate 1, and two sealed bea...

Embodiment 2

[0032] like figure 1 and figure 2 As shown, on the basis of Embodiment 1, preferably, the driving mechanism 6 includes a driving motor 61 that is fixedly connected to the outer wall of the cooling cylinder 2, the output end of the driving motor 61 is fixedly connected with a gear 62, and the outer wall of the cooling cylinder 2 is provided with a gear 62. There is a connecting through hole 63 in which the gear 62 is matched. The outer wall of the side end of the cooling pipe 4 is fixedly sleeved with an external gear ring 64 , and the external gear ring 64 and the gear 62 are meshed with each other.

[0033] In actual use, the driving mechanism 6 rotates the cooling pipe 4, and the rotating cooling pipe 4 enables the air discharged from the rectangular air outlet 8 to completely cool the surface of the pipe, thereby improving the cooling effect and reliability of the pipe. Both the starting air pump 5 and the driving motor 61 are electrically connected to an external power s...

Embodiment 3

[0035] On the basis of Embodiment 1 or Embodiment 2, as figure 1 and figure 2As shown, preferably, the lubricating oil cleaning mechanism 9 includes a U-shaped block 91 fixedly connected to the outer wall of the side end of the cooling pipe 4, a first hook 92 fixedly arranged on the end surface of the same side of the cooling pipe 4, and the U-shaped block 91 There are round holes on the outer walls of the two sides, and each round hole is movably connected with a rotating rod 93, the outer wall of the rotating rod 93 is fixedly connected with an extension rod 94, and the end of the extension rod 94 is connected with a cleaning blade 95.

[0036] In the actual use process, the outer walls of the U-shaped block 91 are provided with circular holes on both sides, and each circular hole is movably connected with a rotating rod 93, the outer wall of the rotating rod 93 is fixedly connected with an extension rod 94, and the end of the extension rod 94 is connected. There is a clea...

Abstract

The invention relates to the technical field of cold rolling processing, in particular to a discharge air cooling device and an air cooling method for a cold rolling pipe mill. The device includes a mounting plate, the upper surface of the mounting plate is fixedly connected with a cooling cylinder, the inner wall of the cooling cylinder is fixedly connected with two sealed bearing assemblies, the inner walls of the two sealed bearing assemblies are jointly fixedly connected with a cooling pipe, and the upper surface of the cooling cylinder is fixed An air pump and a driving mechanism are connected, the output end of the air pump is fixedly connected with an elbow, the bottom of the elbow is fixedly connected with the outer wall of the cooling cylinder, and the outer wall of the side end of the cooling pipe is fixedly connected with a lubricating oil cleaning mechanism. In the present invention, the temperature of the pipe output from the cold rolling mill is comprehensively and rapidly cooled by the cooling cylinder, so as to prevent the deformation of the pipe during transportation after cold rolling, improve the quality and pass rate of the pipe processed by the cold rolling machine, and pass lubricating oil The cleaning mechanism cleans the lubricating oil on the surface of the cooled pipe without manual operation, which reduces the labor intensity of the staff and improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of cold rolling, in particular to a discharge air cooling device and an air cooling method for a cold rolling mill. Background technique [0002] With the rapid development of the national economy and the continuous expansion of new technology fields, the application scope of cold-rolled pipes is becoming wider and wider, and the requirements for its variety and quality are getting higher and higher, especially the development of aviation, rocket, automobile, shipbuilding and other industries , making the demand for various precision, thin-walled, high-strength cold-rolled pipes more and more, at present, the production of these pipes is mainly cold-rolled pipe mills. [0003] Although the cold rolling process is carried out at room temperature, the extrusion and extension movement between the roll and the pipe will inevitably cause certain temperature fluctuations. At present, the pipe is likely to generate...
