Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of spring steel wire processing equipment, specifically a lead bath quenching equipment for processing high-strength spring steel wire. Background Technology
[0002] Spring steel wire is a material specifically used to make springs. It is primarily made of high-carbon steel or alloy steel and has a slender, filament-like shape. It possesses high elasticity and tensile strength, making it suitable for applications requiring elastic deformation and rebound. The main components of spring steel wire are carbon and chromium, and it is widely used in machinery, electronics, and automotive industries.
[0003] Currently, before lead bath quenching, all existing spring steel wires need to be threaded through the wire support and pressure shafts in the lead bath. Because the lead bath contains molten lead, it is impossible to accurately position the wire support and pressure shafts, making threading difficult, time-consuming, and generally inefficient.
[0004] Therefore, we propose to design a lead bath quenching equipment for processing high-strength 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 lead bath quenching device for processing high-strength spring steel wire includes a lead bath pot. An electric push rod is fixedly connected to one side of the outer wall of the lead bath pot. The telescopic end of the electric push rod passes through the lead bath pot and is rotatably connected to a limit wheel. Fixed pulleys are provided on the inner walls of both ends of the lead bath pot. A gas collecting hood is fixedly connected to the top of the lead bath pot. A hydraulic rod is fixedly connected to the center of the top of the gas collecting hood. A pressure plate is provided at the bottom of the telescopic end of the hydraulic rod. Movable wheels are provided at both ends of the bottom of the pressure plate.
[0008] As a preferred embodiment of the lead bath quenching equipment for processing high-strength spring steel wire described in this utility model, a limiting rod is fixedly connected to the inner wall of the lead bath pot away from the electric push rod. The side of the limiting wheel is provided with a shaft hole corresponding to the limiting rod. The limiting wheel and the limiting rod are rotatably connected to each other, so that the limiting wheel can dock with the limiting rod after entering the lead bath pot, thereby improving the stability of the limiting wheel.
[0009] In a preferred embodiment of the lead bath quenching equipment for processing high-strength spring steel wire described in this utility model, an adapter is fixedly connected to the top of the pressure plate, and the adapter is threadedly connected to the end of the hydraulic rod telescopic end, which facilitates the installation of the pressure plate.
[0010] As a preferred embodiment of the lead bath quenching equipment for processing high-strength spring steel wire described in this utility model, the pressure plate has a U-shaped cross-section, and the limiting wheel is located at the center of the bottom of the pressure plate. After the spring steel wire is pressed down into place by the pressure plate, the limiting wheel can be inserted to limit the wire and realize rapid wire threading.
[0011] As a preferred embodiment of the lead bath quenching equipment for processing high-strength spring steel wire described in this utility model, the center of the limiting wheel, the fixed pulley and the movable wheel are all provided with limiting grooves, and the centers of the three limiting grooves are all located in the same vertical plane. Under the limiting of the limiting wheel, the fixed pulley and the movable wheel, it is convenient to thread the spring steel wire and then quench it in the lead bath pot.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention utilizes the cooperation between a pressure plate, a lead bath, and a limiting wheel. The pressure plate presses the spring steel wire into the lead bath, and the limiting wheel passes through the pressure plate to guide the wire instead of the movable wheel, thereby achieving rapid wire threading for lead bath quenching and greatly improving the wire threading efficiency.

[0019] 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.
[0020] 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.

[0021] 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.
[0022] Please see Figure 1-3 This utility model provides a lead bath quenching equipment for processing high-strength spring steel wire, including a lead bath pot 1. An electric push rod 2 is fixedly connected to one side of the outer wall of the lead bath pot 1. The telescopic end of the electric push rod 2 passes through the lead bath pot 1 and is rotatably connected to a limit wheel 3.
[0023] In this embodiment, a limiting rod 4 is fixedly connected to the inner wall of the lead bath 1 on the side away from the electric push rod 2. The side of the limiting wheel 3 is provided with a shaft hole corresponding to the limiting rod 4. The limiting wheel 3 and the limiting rod 4 are rotatably connected to each other, so that after the limiting wheel 3 enters the lead bath 1, it can dock with the limiting rod 4, thereby improving the stability of the limiting wheel 3.
[0024] Both ends of the lead bath pot 1 are equipped with fixed pulleys 5. A gas collecting hood 6 is fixedly connected to the top of the lead bath pot 1. A hydraulic rod 7 is fixedly connected to the center of the top of the gas collecting hood 6. A pressure plate 8 is provided at the bottom of the telescopic end of the hydraulic rod 7. Both ends of the bottom of the pressure plate 8 are equipped with movable wheels 10.
[0025] The pressure plate 8 is fixedly connected to the top of the adapter 9, which is threaded to the telescopic end of the hydraulic rod 7, making it easy to disassemble and replace the pressure plate 8.
[0026] In this embodiment, the pressure plate 8 has a U-shaped cross-section, and the limiting wheel 3 is located at the bottom center of the pressure plate 8. After the spring steel wire is pressed down into place by the pressure plate 8, the limiting wheel 3 can be inserted to limit the steel wire, so as to achieve quick threading.
[0027] In this embodiment, a limiting groove is provided at the center of the limiting wheel 3, the fixed pulley 5 and the movable wheel 10. The centers of the three limiting grooves are all located in the same vertical plane. Under the limiting of the limiting wheel 3, the fixed pulley 5 and the movable wheel 10, it is convenient to thread the spring steel wire and then quench it in the lead bath pot 1.
[0028] In use, connect the hydraulic rod 7 to the external oil pump and the electric push rod 2 to the external power source.
[0029] When threading the wire, the steel wire is directly passed through the lead bath 1. At this time, both ends of the steel wire are located at the top of the two fixed pulleys 5. Then, the hydraulic rod 7 is activated to drive the pressure plate 8 to descend. During the pressing process, the movable wheels 10 at both ends of the plate 8 are used to press the steel wire down until it is pressed down to the bottom of the limit wheel 3. Then, the electric push rod 2 is activated to drive the limit wheel 3 to move into the lead bath 1, so that the limit wheel 3 moves to the top of the pressed steel wire. At this time, one end of the limit wheel 3 is inserted into the limit rod 4, and the limit wheel 3 can rotate at the end of the limit rod 4.
[0030] Finally, the hydraulic rod 7 is activated to lift the pressure plate 8, so that it is no longer pressed against the steel wire. Then, one end of the steel wire is pulled. At this time, the steel wire enters the lead bath 1 and passes through the left fixed pulley 5, the bottom of the middle limit wheel 3 and the top of the right fixed pulley 5 in sequence. At this time, the threading is completed.
[0031] 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.
