Description

Technical Field

[0001] This utility model relates to the field of steel wire processing technology, specifically to a heat treatment device for processing high-toughness spring steel wire. Background Technology

[0002] Spring steel wire is a type of steel wire used to make springs or wire-shaped components. Depending on the application of the spring, there are various types of spring steel wire required for making springs, such as spring steel wire for mattress springs (simply called mattress wire), spring steel wire for shock absorbers, spring steel wire for suspension springs, spring steel wire for engine valves, and spring steel wire for camera shutters, etc. Although there is no unified standard classification name, the quality requirements for these wires are different.

[0003] Currently, during the lead bath quenching process of existing spring steel wires, slag often forms in the molten lead. As the amount of slag in the molten lead increases, it not only easily affects the quenching quality of the steel wire, but also requires workers to clean it regularly, which affects the working efficiency of spring steel wire.

[0004] Therefore, we propose to design a heat treatment equipment for processing high-toughness spring steel wire. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A heat treatment device for processing high-toughness spring steel wire includes a lead bath, a screen horizontally arranged inside the lead bath, a lead water pump fixedly connected to one side of the outer wall of the lead bath, a sealed door on one side of the outer wall of the lead bath, a quenching tank fixedly connected inside the lead bath, two filter screens fixedly connected to the bottom of the quenching tank, a circulation pipe corresponding to the lead water pump fixedly connected to one side of the outer wall of the quenching tank, a bracket inside the quenching tank, positioning posts fixedly connected to both ends of the bottom of the bracket, rollers inside the bracket, and overflow holes at both ends of the quenching tank.

[0008] In a preferred embodiment of the heat treatment equipment for processing high-toughness spring steel wire described in this utility model, the lead water pump's pumping end penetrates through the lead bath and extends inward, the pumping end is located at the bottom of the screen, and the draining end is connected to the circulation pipe. The lead water pump facilitates the circulation of lead liquid in the lead bath and quenching tank.

[0009] In a preferred embodiment of the heat treatment equipment for processing high-toughness spring steel wire described in this utility model, the two filter screens are arranged vertically in parallel, and the bracket is located between the two filter screens, so that the lead slag produced when the spring steel wire is quenched in a lead bath can remain between the two filter screens, which is convenient for unified cleaning later.

[0010] As a preferred embodiment of the heat treatment equipment for processing high-toughness spring steel wire described in this utility model, the bottom of the positioning column is fixedly connected to the bottom of the quenching tank, and two brackets are provided, which are respectively located at both ends of the quenching tank, so as to facilitate the lifting and guiding of the spring steel wire during the feeding of the spring steel wire.

[0011] As a preferred embodiment of the heat treatment equipment for processing high-toughness spring steel wire described in this utility model, the rollers are provided in a plurality of manner, and the plurality of rollers are evenly distributed at the bottom of the bracket. When the steel wire moves on the top of the roller, the friction can be reduced by passing through the arc-shaped outer wall of the roller.

[0012] As a preferred embodiment of the heat treatment equipment for processing high-toughness spring steel wire described in this utility model, the two ends of the roller are rotatably connected to both sides of the inner wall of the bracket. By rotating the roller, friction is reduced when feeding the spring steel wire, making its movement smoother.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes the cooperation between a lead bath, a lead water pump, a quenching tank, a filter screen, and a sieve to facilitate the filtration and removal of slag in the molten lead.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-3 This utility model provides a heat treatment equipment for processing high-toughness spring steel wire, including a lead bath 1, a screen 2 horizontally arranged inside the lead bath 1, a lead water pump 3 fixedly connected to one side of the outer wall of the lead bath 1, a sealing door 8 provided on one side of the outer wall of the lead bath 1, a quenching pool 4 fixedly connected inside the lead bath 1, and two filter screens 5 fixedly connected to the bottom of the quenching pool 4.

[0024] In this embodiment, the two filter screens 5 are arranged vertically in parallel, and the bracket 7 is located between the two filter screens 5, so that the lead slag produced when the spring steel wire is quenched in the lead bath can remain between the two filter screens 5, which is convenient for unified cleaning later.

[0025] A circulation pipe 6 corresponding to the lead water pump 3 is fixedly connected to one side of the outer wall of the quenching pool 4. The water pump 3 has its pumping end penetrating through the lead bath 1 and extending inward. The pumping end of the lead water pump 3 is located at the bottom of the screen 2. The drain end of the lead water pump 3 is connected to the circulation pipe 6. The lead water pump 3 facilitates the circulation of lead liquid in the lead bath 1 and the quenching pool 4.

[0026] The quenching pool 4 is equipped with a bracket 7. Both ends of the bottom of the bracket 7 are fixedly connected to positioning columns 9. The bottom of the positioning columns 9 is fixedly connected to the bottom of the quenching pool 4. There are two brackets 7, which are located at the two ends of the quenching pool 4 respectively. When the spring steel wire is fed, it is convenient to lift and guide the steel wire spring.

[0027] The bracket 7 is equipped with a roller 10, and the quenching pool 4 has overflow holes 11 at both ends.

[0028] In this embodiment, a plurality of rollers 10 are provided, and the plurality of rollers 10 are evenly distributed at the bottom of the bracket 7. When the steel wire moves on the top of the roller 10, the friction can be reduced by passing through the arc-shaped outer wall of the roller 10.

[0029] The two ends of the roller 10 are rotatably connected to the inner walls of the bracket 7. The rotation of the roller 10 facilitates the reduction of friction when feeding the spring steel wire, making its movement smoother.

[0030] In use, a sufficient amount of molten lead is heated in the lead bath 1, and then pumped into the quenching tank 4 by the lead water pump 3. The molten lead is then discharged back into the lead bath 1 through the overflow hole 11 for circulation. The spring steel wire enters through the overflow hole 11 at one end of the quenching tank 4, passes through two brackets 7, and exits through the other overflow hole 11. During this process, the liquid level of the molten lead is always higher than the overflow hole 11, which facilitates the quenching of the steel wire by immersing it in the molten lead.

[0031] Impurities generated during the quenching process of spring steel wire are blocked by the filter screens 5 on both sides and always accumulate between the two filter screens 5. Larger slag particles fall to the bottom of the quenching pool 4 and are cleaned up later. Smaller slag particles can flow into the lead bath 1 below with the flow of lead liquid, thereby reducing the impact of impurities in lead liquid on the quenching of spring steel wire and reducing the impurities adhering to the steel wire.

[0032] As the lead slag is filtered by the screen 2, it can stay on the top of the screen 2, so that the lead liquid circulated by the lead water pump 3 has fewer impurities and is purer. The lead liquid circulates into the quenching pool 4, which facilitates the continuous quenching of steel wire.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
