Description

Technical Field

[0001] This utility model belongs to the technical field of steelmaking equipment, and specifically relates to an improved structure of a cooling water nozzle for high-speed wire rod. Background Technology

[0002] When our company produces steel cord, the newly installed water pump can ensure a final rolling speed of 78m / s. After a period of use (about 20 days), the final rolling speed must be reduced to 76m / s because the spinning temperature is too high in order to operate normally. After analysis by our technicians, we found that this was caused by water pump wear, which reduced water pressure and flow. Since replacing it with a high-flow water pump is costly and there is no space to install it, our technicians improved the nozzle structure of the water-cooled running channel to solve this problem.

[0003] Among existing patents, application number 201921172616.1, entitled "An Improved Structure of a Water-Cooled Running Tank," includes running tanks a and b with identical structures, connected and fixed by pins. Both running tanks a and b include a rectangular running tank body. A semi-circular groove a is provided on the front side of the running tank body, and a conical groove a is provided at the left end of the semi-circular groove a. A semi-circular groove b is provided on the rear side of the running tank body, and a conical groove b is provided at the left end of the semi-circular groove b. A pressure plate is provided in the middle of the running tank body, symmetrically arranged through the running tank body. Brackets are symmetrically arranged on the left and right sides of the pressure plate. Ear seats are symmetrically arranged on the upper and lower surfaces of the running tank body, and pin holes are provided on the ear seats. This application mainly solves the problem of slotting on both sides of a running tank to allow steel bars to pass through, improving efficiency. However, it cannot solve the problem of insufficient water flow, resulting in low final rolling speed and affecting production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an improved structure for cooling water nozzles used in high-speed wire rod production, and to avoid the problem of low wire rod production efficiency caused by insufficient flow due to water pump wear.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] An improved cooling water nozzle structure for high-speed wire rods includes an upper half and a lower half of a water tank. The upper and lower half of the water tank have identical structures and are fastened together to form a wire running channel. The lower half of the water tank includes a lower nozzle section and a lower running channel body fixedly connected to the lower nozzle section. The upper half of the water tank includes an upper nozzle section and an upper running channel body. The upper and lower nozzle sections have identical structures and constitute a single nozzle section. The nozzle section has a conical hole for guiding the wire entry and a wire-passing hole concentric with the conical hole at its center. The lower and upper running channel bodies constitute a running channel body. The running channel body has a running channel hole concentric with the wire-passing hole. A water inlet chamber is formed between the running channel body and the nozzle section. The water inlet chamber communicates with the running channel hole.

[0007] Furthermore, the lower nozzle portion is provided with a lower conical hole and a lower threading hole concentric with the lower conical hole.

[0008] Furthermore, the lower nozzle portion includes a fixing portion fixedly connected to the lower running tank body, a positioning portion positioned to the lower running tank body, a lower cylindrical water inlet portion fixedly connected to the positioning portion, and a semi-conical water inlet portion fixedly connected to the semi-cylindrical water inlet portion.

[0009] Furthermore, the lower half of the running tank is provided with a lower half positioning hole, a lower half cylindrical water inlet hole, and a lower half conical water inlet hole; the positioning part is inserted into the lower half positioning hole; the semi-cylindrical water inlet part and the lower half cylindrical water inlet hole form a lower half cylindrical water inlet cavity; the semi-conical water inlet part and the lower half conical water inlet hole form a lower half conical water inlet cavity that communicates with the lower half cylindrical water inlet cavity.

[0010] The upper cylindrical water inlet chamber of the upper nozzle section and the lower cylindrical water inlet chamber of the lower nozzle section constitute a cylindrical water inlet chamber;

[0011] The upper conical water inlet cavity of the upper nozzle section and the lower conical water inlet cavity of the lower nozzle section constitute a conical water inlet cavity; the cylindrical water inlet cavity is concentric with and connected to the conical water inlet cavity.

[0012] Furthermore, the distance between the small end face of the conical water inlet cavity and the small end face of the lower half-conical water inlet hole is 2mm.

[0013] Furthermore, the surface of the conical water inlet is provided with a semi-spiral water channel.

[0014] Furthermore, the conical water inlet section is provided with an auxiliary water inlet hole that communicates with the lower half of the wire hole.

[0015] Compared with the prior art, the significant beneficial effects achieved by this utility model are as follows:

[0016] The tapered hole allows the wire to be guided before entering the slot, meaning that even if the wire is slightly misaligned with the slot, it can still enter normally without precise adjustment, thus reducing adjustment time.

[0017] The conical water inlet cavity can be designed to increase the water flow rate and cool the wire as quickly as possible.

[0018] The water flow is accelerated by the spiral water channel set in the conical water inlet;

[0019] By using auxiliary water inlets, some cooling water is pre-flowed into the wire threading holes to cool the wire in advance, thereby maximizing the rolling speed and improving efficiency. Attached Figure Description

[0030] Example 1

[0031] like Figure 1 , Figure 2 As shown,

[0032] An improved cooling water nozzle structure for high-speed wire rods includes an upper half 1 and a lower half 2 of a water tank. The upper half 1 and lower half 2 have identical structures and are fastened together to form a wire running groove 3 for cooling the wire. The upper half 1 and lower half 2 are fixed using a clamp-on and then bolt method, which is existing technology and will not be described further.

[0033] The lower half 2 of the water tank includes a lower nozzle section 22 and a lower running tank body 21 fixedly connected to the lower nozzle section 22; the upper half 1 of the water tank includes an upper nozzle section and an upper running tank body; the upper nozzle section and the lower nozzle section 22 constitute a nozzle section; the nozzle section has a conical hole for guiding the wire in and a wire-passing hole concentric with the conical hole at its center; the lower running tank body 21 and the upper running tank body constitute a running tank body; the running tank body has a running tank hole concentric with the wire-passing hole; a water inlet cavity is formed between the running tank body and the nozzle section; the water inlet cavity communicates with the running tank hole. The lower nozzle section 22 and the running tank body are fixedly connected by bolts.

[0034] like Figure 1 As shown, the lower nozzle portion 22 is provided with a lower conical hole 221 and a lower wire-passing hole 222 concentric with the lower conical hole 221. The upper nozzle portion 21 is provided with an upper conical hole, and the lower conical hole 221 and the upper conical hole form a complete conical hole. The wire enters from the large end of the conical hole and exits from the small end (e.g., ...). Figure 1 (The arrow direction) The tapered hole design allows the wire to be threaded in without being completely aligned with the slotted hole.

[0035] The lower nozzle section 22 includes a fixing part 223 fixedly connected to the lower running tank body 21, a positioning part 229 positioned by the lower running tank body 21, a cylindrical water inlet part 224 fixedly connected to the positioning part 229, and a conical water inlet part 226 fixedly connected to the cylindrical water inlet part 224. The positioning part 223, the positioning part 229, the cylindrical water inlet part 224, and the conical water inlet part 226 are an integral structure, manufactured by casting and then machined to the design dimensions.

[0036] The fixing part 223 is fixed to the lower half of the running trough body 21 by bolts;

[0037] The lower half of the running tank 21 is provided with a lower half positioning hole, a lower half cylindrical water inlet hole and a lower half conical water inlet hole 211; the positioning part 229 is inserted into the lower half positioning hole; the cylindrical water inlet part 224 and the lower half cylindrical water inlet hole form a lower half cylindrical water inlet cavity 225; the conical water inlet part 226 and the lower half conical water inlet hole 211 form a lower half conical water inlet cavity that communicates with the lower half cylindrical water inlet cavity 225.

[0038] The lower half 2 of the water tank is also equipped with a semi-conical water inlet cavity and a semi-cylindrical water inlet cavity.

[0039] After the upper half 2 of the water tank is engaged with the lower half 1 of the water tank, a complete cylindrical water inlet cavity and a conical water inlet cavity are formed. The water used for cooling is accelerated through the conical water inlet cavity and then cools the wire, thereby improving the cooling efficiency.

[0040] A water inlet valve 230 is provided on the side wall of the cylindrical water inlet section 224, and the valve 230 is connected to the cylindrical water inlet cavity.

[0041] The distance between the small end face of the conical water inlet 226 and the small end face of the lower conical water inlet 211 is 2mm. If this distance is too small, the water volume will be insufficient and easily vaporized; if the distance is too large, the water flow rate will be insufficient and unable to carry away enough heat, forcing the production line to slow down and affecting the efficiency of wire production. After repeated experimentation, a distance of 2mm was found that neither the water volume is too small, causing water vaporization, nor the wire speed is too large, thus ensuring a speed of 78m / s.

[0042] The working process of this utility model,

[0043] Once the wire rod production line is started, valve 230 is opened to allow water to flow from the cylindrical inlet chamber into the conical inlet chamber.

[0044] Because there is a gap (2mm) between the small end face of the conical water inlet 226 and the small end face of the lower half-conical water inlet 211,

[0045] Cooling water cools the passing wire, and then the water flows with the wire to the outside of the running tank for natural cooling and recycling.

[0046] Example 2

[0047] The structure of this embodiment is largely the same as that of Embodiment 1.

[0048] The difference is that,

[0049] like Figure 5As shown, the surface of the conical water inlet 226 is provided with semi-spiral water channels 228. Two semi-spiral water channels form a complete spiral water channel. After passing through the spiral water channel, the cooling water has an accelerating effect, which can accelerate the water flow and cool the wire.

[0050] Example 3

[0051] The structure of this embodiment is largely the same as that of embodiment 2.

[0052] The difference is that,

[0053] like Figure 1 and Figure 4 As shown, the conical water inlet 226 is provided with an auxiliary water inlet 227 that communicates with the lower half of the wire threading hole 222. The auxiliary water inlet 227 allows a small amount of water to cool the wire in advance, while also preventing the high temperature of the wire from affecting the nozzle and causing nozzle deformation.

[0054] The auxiliary water inlet 227 is inclined in the direction of wire travel to prevent water from running out or dripping.

[0055] Currently, the technical solution of this application has undergone pilot testing, which is a small-scale experiment before the product is mass-produced. After the pilot testing was completed, a user survey was conducted on a small scale, and the survey results showed that user satisfaction was high. Now, preparations have begun for the formal production and industrialization of the product (including intellectual property risk warning surveys).
