Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper rod annealing and wire drawing, and more particularly to a multi-head annealing cooling device. Background Technology
[0002] During the entire annealing and wire drawing process, the copper wire needs to undergo a cooling process. The conventional cooling method is to place the copper wire in a container with multiple vertical grooves inside. The container also has a first water inlet located inside the grooves. The copper wire is located in the grooves, and cooling water flows out from the first water inlet. After the water comes into contact with the copper wire, it flows out from the bottom of the grooves.
[0003] In reality, this cooling method suffers from uneven cooling of the copper wires. This is because all the first water inlets are located on the same water supply pipe. Specifically, the water supply pipe is horizontal, and the first water inlets are sequentially located on the outer wall of the water supply pipe from left to right. One end of the water supply pipe is the second water inlet, and the other end is the second water outlet. When cooling water is poured in, due to the high flow rate and long flow distance of the liquid, as well as the frictional resistance inside the pipe, the pressure distribution at each first water inlet will be irregular. Therefore, this results in a significant difference in the inflow of cooling water in each wire groove, which causes the aforementioned problem of uneven cooling between the copper wires. Utility Model Content
[0004] To address the aforementioned problems, this invention provides a multi-head annealing cooling device, which aims to solve the problem of uneven cooling among various copper wires.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multi-head annealing cooling device, comprising a cooling box, a water supply pipe and a plurality of wire grooves for copper wires to pass through, wherein the outer wall of the water supply pipe is provided with a plurality of arrayed water outlets along the length direction, the water outlets of the water supply pipe are connected to the opening structure provided on the inner surface of the wire grooves, one end of the water supply pipe is a water inlet and the other end is a water outlet, characterized in that the cooling box is provided with a groove communicating with the aforementioned wire grooves.
[0006] Furthermore, grooves are set in the middle area of each wire groove, dividing the wire groove into a first part and a second part, with the opening structure located in the groove.
[0007] Furthermore, the cooling box is also equipped with winding posts located at both ends of the wire slot for wire passage.
[0008] Furthermore, the first part is equipped with a nitrogen outlet.
[0009] Furthermore, the groove, the first part, and the second part are integrally formed.
[0010] The beneficial effects of this utility model are:
[0011] To address the pressure difference between the various wire slots, this invention provides a groove on the inner surface of the cooling box. This groove is interconnected with each wire slot, aiming to balance the pressure difference between them and ensure a uniform flow of cooling water into each slot. This, in turn, solves the problem of uneven cooling between the copper wires. Attached Figure Description
[0012] Figure 1 This is a cross-sectional view of the present invention.
[0013] Figure 2 This is a cross-sectional view of a water pipeline. Detailed Implementation
[0014] Please see Figure 1-2 As shown, a multi-head annealing cooling device includes a cooling box 1, with copper wires entering from one end of the cooling box 1 and exiting from the other end of the cooling box 1.
[0015] The cooling box 1 is equipped with a water supply pipe 2 and multiple wire grooves for copper wires to pass through. The outer wall of the water supply pipe 2 is provided with multiple arrayed water outlets 21 along the length direction. The water outlets 21 of the water supply pipe are connected to the opening structure 3a provided on the inner surface of the wire groove. One end of the water supply pipe 2 is a water inlet 22 and the other end is a water outlet 23. The cooling box 1 is characterized by having a groove 4 that connects the wire grooves to each other.
[0016] To address the pressure difference between the various wire slots, this invention provides a groove 4 on the inner surface of the cooling box 1. This groove 4 is interconnected with each wire slot, and its purpose is to balance the pressure difference between the various wire slots, ensuring that the cooling water inflow into each wire slot is uniform, thereby solving the problem of uneven cooling between copper wires.
[0017] Furthermore, the groove 4 divides the wire groove into a first part 31 and a second part 32, and the opening structure 3a is located in the groove 4; this setting position of the groove 4 is the optimal way in this embodiment, and under this design, the air pressure balance adjustment between the wire grooves is the fastest.
[0018] Furthermore, the cooling box 1 is also equipped with winding posts 5 distributed at both ends of the wire groove for passing wires; its purpose is to act as a conductor, allowing the copper wire to smoothly enter the cooling box 1 and leave the cooling box 1.
[0019] Furthermore, the first part 31 is provided with a nitrogen outlet 31a, the purpose of which is to form a protective layer on the copper wire to prevent copper oxidation. The first part 31 is also provided with a high-temperature steam outlet 31b, where nitrogen reacts on the copper wire under high temperature, thereby forming a protective layer on the surface of the copper wire.
[0020] Furthermore, the groove 4, the first part 31, and the second part 32 are integrally formed, which has the advantage of low production cost.
[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
