Description

Technical Field

[0001] The utility model relates to the technical field of high-speed wire materials, in particular to a high-speed wire material flying shear conduit. Background Art

[0002] The flying shear of high-speed wire rods places high demands on the rolling line tooling. When rolling the wire rods, due to the high temperature of the wire rods themselves, after passing through the inside of the conduit, they come into contact with the conduit, which will cause the temperature inside the conduit to rise. As the wire rods move and rub inside the conduit, it will cause greater wear inside the conduit, greatly reducing the service life of the conduit.

[0003] Some solutions have also been provided in the prior art, such as the Chinese patent: application number 202011236926.2, publication date: 2022-12-06, which discloses a high-speed wire slow cooling tube outer wall cooling device, which cools the slow cooling tube by cooling water, so that the slow cooling tube maintains a constant wear-resistant body temperature during the wire production process.

[0004] However, this cooling method involves placing the conduit on a cooling device, which is relatively complex and occupies a large area. The conduit used needs to be replaced according to different specifications. Due to the large number of rolling specifications, the conduit needs to be replaced frequently during the production process, the work intensity is high, and the conduit consumption is high, resulting in high costs.

[0005] Therefore, the utility model provides a high-speed wire flying shear conduit. Utility Model Content

[0006] The purpose of the utility model is to propose a high-speed wire flying shear conduit, which solves the problem that when the existing wire is rolled, the temperature of the wire itself is high, which will cause greater wear inside the conduit. At the same time, due to the large number of rolled specifications, the conduit needs to be replaced frequently. The utility model reduces the temperature inside the conduit during the rolling of the wire, reduces wear, and increases the service life of the conduit. There is no need to frequently replace the conduit, which reduces labor intensity and saves costs.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a high-speed wire flying shear conduit, comprising:

[0008] tube core;

[0012] An extension tube is sleeved on an end of the tube core away from the tube head, and the extension tube is used to change the diameter of the outlet.

[0013] Preferably, the first curved pipe and the second curved pipe are connected to both ends of the sleeve via fixing rings respectively.

[0014] Preferably, the extension tube comprises:

[0015] A round tube, sleeved on one end of the tube core away from the tube head;

[0016] a conical tube, the largest outer diameter end of which is connected to the circular tube;

[0017] The tail pipe has one end connected to the end with the smallest outer diameter of the circular pipe.

[0018] Preferably, a rectangular groove is axially opened at one end of the circular tube, and the rectangular groove radially penetrates the circular tube.

[0019] Preferably, two connecting blocks are provided on the circular tube, and the two connecting blocks are respectively located on both sides of the rectangular groove, and the two connecting blocks are used to fix the circular tube on the tube core.

[0027] The following is a further description of the method of use of the present invention in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1 and Figure 2 As shown, a high-speed wire flying shear conduit comprises:

[0029] Die 1;

[0030] A tube head 2 is provided at one end of the tube core 1;

[0031] Also includes:

[0032] The sleeve 3 is sleeved on the tube core 1. The sleeve 3 and the tube core 1 form a closed space. The two ends of the sleeve 3 are respectively provided with a first elbow 4 and a second elbow 5 for the flow of cooling water to cool the tube core 1;

[0033] After the wire passes through the tube core 1 from the tube head 2, due to the high temperature of the wire, generally around 1000°C, it will pass through the tube core 1 and through high-speed friction and its own high temperature, the temperature of the tube core 1 will rise sharply, which can easily cause damage to the tube core 1. Therefore, it is necessary to insert a sleeve 3 into the outside of the tube core 1 and pass cooling water between the sleeve 3 and the tube core 1 to cool the tube core 1, which greatly improves the service life of the tube core 1 and saves production costs.

[0034] The extension tube 6 is sleeved on the end of the tube core 1 away from the tube head 2, and the extension tube 6 is used to change the diameter of the outlet.

[0035] It should be noted that, since wires of different specifications need to be produced, in order to reduce the frequency of replacement of the tube core 1, an extension tube 6 is installed at the outlet end of the tube core 1. When the wire passes through the extension tube 6 of corresponding specifications, corresponding wires will be produced. Generally, when the difference is not large, the extension tube 6 can be replaced. When the difference is large, the tube core 1 can be directly replaced, thereby realizing the production of wires of different diameters according to the extension tubes 6 of different diameters, reducing the frequency of replacement of the tube core 1 and reducing labor intensity.

[0036] The first elbow 4 and the second elbow 5 are respectively connected to both ends of the sleeve 3 through a fixing ring 7. Water enters and exits through the first elbow 4 and the second elbow 5, thereby realizing the circulation of cooling water and greatly improving the heat exchange efficiency of the tube core 1.

[0037] The extension tube 6 includes:

[0038] The circular tube 61 is sleeved on the end of the tube core 1 away from the tube head 2;

[0039] The tapered tube 62, whose largest outer diameter end is connected to the circular tube 61;

[0040] One end of the tail pipe 63 is connected to the end with the smallest outer diameter of the circular tube 61. According to the diameter of the tail pipe 63, the wire rod passing through the tail pipe 63 can produce a wire rod with a corresponding diameter.

[0041] A rectangular groove 611 is axially opened at one end of the circular tube 61, and the rectangular groove 611 radially penetrates the circular tube 61. The rectangular groove 611 is to ensure that the circular tube 61 can be sleeved on tube cores 1 of different sizes, so that the circular tube 61 has a certain adjustment range and improves the applicability of the extension tube 6.

[0042] Two connecting blocks 612 are provided on the circular tube 61 , and the two connecting blocks 612 are respectively located on both sides of the rectangular groove 611 . The two connecting blocks 612 are used to fix the circular tube 61 on the tube core 1 .

[0043] The two connecting blocks 612 are connected by bolts 613. The extension tube 6 can be fixed to the tube core 1 through the connecting tube and the bolts 613. The connecting block 612 can not only strengthen the force of the bolts 613, but also greatly improve the connection strength of the extension tube 6 on the tube core 1. In addition, the connection through the bolts 613 can also be easily disassembled and replaced.

[0044] Working process: When the wire is rolled, since the stability of the wire is about 1000℃, the wire passes through the tube head 2 into the tube core 1 and passes out through the tail pipe 63 on the extension tube 6. When the wire moves in the tube core 1, the first bend 4 will be filled with cooling water, so that the cooling water enters the inside of the sleeve 3 and flows out from the second bend 5 for circulating cooling, thereby cooling the tube core 1 and reducing the wear of the tube core 1. Then the wire will pass through the tapered tube 62 on the extension tube 6 into the inside of the tail pipe 63, and according to the diameter of the tail pipe 63, the wire can reach the corresponding diameter specification.

[0045] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
