Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of high line air pipe for steel industry, especially a kind of high line finishing mill with back blowing function air pipe. BACKGROUND

[0002] When producing round steel wire rod or ribbed steel bar wire rod in high-speed wire rod production line, air pipe is used to correct and guide the movement of round steel wire rod or ribbed steel bar wire rod.

[0003] Air pipe is usually made of a pipe, which is provided with a support seat, and the support seat is usually connected to the workbench of high-speed wire rod production line. A hole is also provided in the center of the air pipe. When the round steel wire rod or ribbed steel bar wire rod moves, it will pass through the hole. The hole can correct the shape of the round steel wire rod or ribbed steel bar wire rod when it moves, so that they are more straight.

[0004] However, the existing air pipe design still has some shortcomings. For example, when the round steel wire rod or ribbed steel bar wire rod moves, it will carry cooling water. The existing air pipe cannot block the cooling water from moving with the round steel wire rod or ribbed steel bar wire rod. This will cause the cooling water to flow out of the finishing mill group with the round steel wire rod or ribbed steel bar wire rod, affecting the stable detection of red steel by heat detection, and the unstable signal often causes the water tank valve and pinch roll to malfunction, which in turn causes the finishing mill outlet to pile up steel, seriously affecting the production stability and efficiency. SUMMARY

[0005] In view of the problem that the existing air pipe cannot block the cooling water from moving with the round steel wire rod or ribbed steel bar wire rod, affecting the stable detection of red steel by heat detection, and seriously affecting the production stability and efficiency, the utility model is proposed.

[0006] To solve the above technical problems, the utility model provides the following technical scheme: a kind of high line finishing mill with back blowing function air pipe, comprising,

[0007] The connecting assembly comprises a connecting seat, a connecting hole provided through the end of the connecting seat, and a side hole opened on one side of the connecting seat; and,

[0008] The first pipe group is connected to the inner wall of the connecting hole, and the second pipe group is connected to one side of the connecting hole.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1

[0028] Reference Figs. 1-4 This is the first embodiment of the present invention, which provides a high-speed wire rod finishing mill with a back-blowing air passage pipe, comprising:

[0029] The connecting assembly 100 includes a connecting seat 101, a connecting hole 102 extending through the end of the connecting seat 101, and a side hole 103 formed on one side of the connecting seat 101. The connecting seat 101 needs to be placed on the workbench of the production line and fixed with bolts. Then, the first tube group 200 and the second tube group 300 are connected to the connecting seat 101.

[0030] It should be noted that when assembling the empty tube, the air guide tube needs to be welded to the side hole 103.

[0031] The first pipe assembly 200 is connected to the inner wall of the connecting hole 102, and the second pipe assembly 300 is connected to one side of the connecting hole 102. When the air guide pipe is welded to the side hole 103, high-pressure air is output to the side hole 103 through the air guide pipe. The high-pressure air will enter the connecting hole 102 and will also enter the first pipe assembly 200 and the second pipe assembly 300. In this way, when the round steel wire rod or ribbed steel wire rod carries cooling water through the first pipe assembly 200 and the second pipe assembly 300, the high-pressure air can block the water flow, thereby preventing the cooling water from flowing out of the finishing mill along with the round steel wire rod or ribbed steel wire rod and affecting the stability detection of red steel by the hot inspection.

[0032] Example 2, which is based on the previous example, provides an air intake method.

[0033] The connecting hole 102 and the side hole 103 are interconnected and perpendicular to each other. The top of the connecting seat 101 is provided with a through hole 104, which is interconnected with the connecting hole 102. The through hole 104 is used to connect bolts. When the first pipe group 200 and the second pipe group 300 are connected to the connecting hole 102, the first pipe group 200 and the second pipe group 300 are clamped by connecting bolts. Alternatively, corresponding threaded holes are preset on the first pipe group 200 and the second pipe group 300 to connect bolts.

[0034] The first tube assembly 200 includes a front guide tube 201, a front channel 202 extending through one side of the front guide tube 201, and a nozzle outer ring 203 extending through one side of the front guide tube 201. The front guide tube 201 is cylindrical, and the front channel 202 is provided in its center. When moving, the round steel wire rod or ribbed steel wire rod will first enter the front channel 202 and then be guided to other components through the front channel 202.

[0035] It should be added that nozzle outer rings 203 are provided on both sides of the front guide tube 201. The nozzle outer ring 203 is specifically a groove recessed into the front guide tube 201, and its cross-sectional shape is V-shaped.

[0036] The outer wall of the front guide tube 201 is connected to the inner wall of the connecting hole 102. After the front guide tube 201 is connected to the connecting hole 102, the connecting seat 101 can provide sufficient support for the front guide tube 201, thereby supporting the round steel wire rod or ribbed steel wire rod to pass through the front guide tube 201.

[0037] The second tube assembly 300 includes a rear guide tube 301, a nozzle 302 disposed on one side of the rear guide tube 301, and a rear sizing channel 303 that passes through one side of the rear guide tube 301. When the round steel wire rod or ribbed steel wire rod passes through the front sizing channel 202, it will enter the rear sizing channel 303, which will guide the round steel wire rod or ribbed steel wire rod to move out of the finishing mill.

[0038] It should be noted that the nozzle 302 is only located at one end of the rear guide tube 301. It is protruding and its overall shape is close to a cone. It also has a through hole with the same diameter as the rear guide tube 303 in the middle.

[0039] The outer wall of the rear conduit 301 is connected to the inner wall on the other side of the connecting hole 102. The front ligature 202 and the rear ligature 303 are located on the same horizontal line and have the same diameter. After the rear conduit 301 is connected to the connecting hole 102, the entire empty tube is assembled. Subsequently, the air guide tube needs to be connected to the side hole 103, and the empty tube can be put into use.

[0040] The nozzle 302 is located inside the nozzle outer ring 203, and the side hole 103 is located at the connection between the nozzle 302 and the nozzle outer ring 203. The nozzle 302 and the nozzle outer ring 203 do not contact each other. Therefore, when the high-pressure gas enters the connecting hole 102 through the side hole 103, it will enter the front binding channel 202 and the rear binding channel 303 through the middle of the nozzle 302 and the nozzle outer ring 203. In this way, the high-pressure gas will blow towards the round steel wire rod or the ribbed steel wire rod. At this time, if there is residual coolant in the round steel wire rod or the ribbed steel wire rod, the high-pressure gas will prevent the coolant from continuing to move with the round steel wire rod or the ribbed steel wire rod.

[0041] Example 3 is based on the previous example, and provides another air intake method.

[0042] The connecting assembly 100 includes a connecting seat 101, a connecting hole 102 penetrating the end of the connecting seat 101, a first pipe group 200 connected to the inner wall of the connecting hole 102, and a second pipe group 300 connected to one side of the connecting hole 102. Multiple through holes can be opened on the connecting seat 101, the front guide pipe 201, and the rear guide pipe 301, and these through holes can be connected to air guide pipes. In this way, when the round steel wire rod or the ribbed steel wire rod moves, high-pressure gas can be blown towards the round steel wire rod or the ribbed steel wire rod from multiple directions, which can better block the coolant.
