Description

TECHNICAL FIELD

[0001] The utility model relates to galvanization processing device technical field, concretely is a kind of tension torsion spring surface galvanization processing device. BACKGROUND

[0002] In today's industrial production field, tension torsion spring is widely used in automobile manufacturing, mechanical equipment, electronic appliances and many other industries as a key elastic element. However, the spring is easily eroded by environmental factors such as humid air, acid-base medium during long-term use, which can cause rust and corrosion of the spring, and thus seriously affect its mechanical properties and service life.

[0003] Traditional protection methods have been difficult to meet the increasingly stringent industrial needs. Early simple paint protection is prone to peeling, and cannot provide durable and stable protection. Ordinary rust-proof oil is applied, and in some high-temperature, high-humidity or chemically contaminated environments, the protection effect is greatly reduced.

[0004] With the development of surface treatment technology, galvanizing has become a popular solution. Compared with other protection methods, the galvanized layer can provide a reliable barrier for the spring due to its good corrosion resistance, effectively blocking external erosion factors. However, some existing galvanizing equipment has many drawbacks. Some small galvanizing devices lack efficient stirring and mixing mechanisms, resulting in uneven distribution of zinc liquid composition, uneven quality of spring galvanizing, and problems such as local underplating or large thickness differences of zinc layer. Some equipment is not user-friendly, such as the cumbersome loading and unloading process of the spring, which consumes a lot of manpower and time and reduces production efficiency.

[0005] In summary, it is urgent to develop a tension torsion spring surface galvanizing processing device that can ensure high-quality galvanizing and is easy to operate. SUMMARY

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figures 1-3 As shown, an embodiment of the present invention provides a galvanizing processing device for tension, compression and torsion springs, including a galvanizing tank 1, a drain valve pipe connected to one end of the galvanizing tank 1, four fixed seats 2 fixedly connected around the galvanizing tank 1, and a column 3 fixedly connected to one side of each fixed seat 2.

[0027] The galvanizing tank 1 is the main container for holding molten zinc and carrying out the galvanizing operation. The four fixed bases 2 around the perimeter are connected to the columns 3. The perforated mounting plates at the bottom of the columns 3 are used to stably fix the entire device in the work area, ensuring that the device will not shake or shift during operation, and providing a stable foundation for the galvanizing process.

[0028] The top of the galvanized tank 1 is movably fitted with a cover plate 4. A large motor 6 is fixedly installed at the center of the bottom of the galvanized tank 1. The output end of the large motor 6 extends through the galvanized tank 1 and is fixedly connected to an inner cylinder 7. The diameter of the inner cylinder 7 is smaller than the diameter of the galvanized tank 1. Several through holes 8 are opened on the cylinder wall of the inner cylinder 7. A positioning post 9 is installed in the inner cylinder 7.

[0029] A large motor 6 is installed at the center of the bottom of the galvanizing tank 1, and its output drives the inner cylinder 7 to rotate. The diameter of the inner cylinder 7 is smaller than that of the galvanizing tank 1, and the through holes 8 on the cylinder wall allow the molten zinc inside and outside the inner cylinder 7 to flow. Two rings of positioning posts 9 are set for vertically mounting springs, keeping the springs in a stable position during the galvanizing process; at the same time, they isolate the space inside the inner cylinder 7, increasing the number of springs that can be placed and improving processing efficiency.

[0030] Four stirring rods 11 are provided in the gap between the inner cylinder 7 and the galvanized tank 1. Stirring blades 12 are fixedly connected to the stirring rods 11. The stirring rods 11 extend through the galvanized tank 1 to the outside and are fixedly connected to the small motor 10.

[0031] Four small motors 10 are fixed to the bottom of the galvanizing tank 1, each driving a stirring rod 11 to rotate. The stirring blades 12 on the stirring rods 11 stir the molten zinc in the gap between the galvanizing tank 1 and the inner cylinder 7. By setting different speeds and rotation directions, the stirring effect is enhanced, ensuring a uniform distribution of the zinc liquid composition, guaranteeing the consistency of the spring galvanizing quality, and avoiding problems such as localized missed plating or excessive differences in zinc layer thickness.

[0032] Principle: The mixture of zinc powder, accelerator, lubricant and other substances is thoroughly stirred and collided with the spring in a specific container, so that the zinc powder particles are deposited on the surface of the spring and form a zinc plating layer.

[0033] When the galvanizing device for tension, compression, and torsion springs is in operation, the springs are mounted on the positioning posts 9 of the inner cylinder 7. The positioning posts 9 allow for vertical installation of the springs and also isolate the space within the inner cylinder 7, facilitating the placement of more springs. Simultaneously, the large motor 6 at the center of the bottom of the galvanizing tank 1 starts, driving the inner cylinder 7 to rotate. The through-holes 8 on the inner cylinder 7 wall allow communication between the internal and external liquids. At the same time, four small motors 10 at the bottom of the galvanizing tank 1 drive the stirring rods 11 to rotate. The stirring blades 12 on the stirring rods 11 agitate the molten zinc in the gap between the galvanizing tank 1 and the inner cylinder 7. The different speeds and directions of the small motors 10 enhance the agitation effect, ensuring a uniform distribution of the zinc composition. During this process, the molten zinc continuously flows and enters the inner cylinder 7 through the through-holes 8, making full contact with the springs and achieving surface galvanizing of the tension, compression, and torsion springs.

[0034] like Figure 1 As shown, in some embodiments, four columns 3 are provided, and a perforated mounting plate is fixedly connected to the bottom of each column 3; a stable support structure and a reliable installation method are the foundation for the safe operation of the device. Once the device is stably fixed, it can avoid safety accidents caused by shaking or displacement, such as zinc liquid splashing and injuring people, or equipment damage.

[0035] like Figure 1 As shown, in some embodiments, the diameter of the cover plate 4 is larger than the diameter of the galvanizing tank 1, and a protective cover is fixedly connected to the edge of the cover plate 4, covering the galvanizing tank 1; the cover plate 4 with a larger diameter and a protective cover can effectively block the splashing zinc liquid, avoid the zinc liquid splashing onto the operator and causing burns, or splashing onto the surrounding equipment and affecting the normal operation and service life of the equipment, thus ensuring the safety of the operator and the cleanliness of the working environment.

[0036] like Figure 1As shown, in some embodiments, an arc-shaped handle 5 is fixedly connected to the cover plate 4; the arc-shaped handle 5 conforms to ergonomic design and is convenient for operators to grip.

[0037] like Figure 2 As shown, in some embodiments, the small motors 10 are fixedly connected to the bottom of the galvanizing tank 1, and four of them are provided; the four small motors 10 drive the stirring rods 11 to rotate, so that the stirring blades 12 can stir the zinc liquid from multiple angles and in all directions.

[0038] like Figure 3 As shown, in some embodiments, the rotation speed and direction of the small motor 10 are set differently. Different rotation speeds and directions of the small motor 10 cause the stirring rod 11 and stirring blade 12 driven by them to agitate the molten zinc in different ways. Some stirring blades 12 rotate at high speeds, generating strong local water flow impact forces; others rotate at low speeds, responsible for propelling a larger area of ​​molten zinc to flow slowly. Different rotation directions create a complex and turbulent flow state of the molten zinc in the gap between the galvanizing tank 1 and the inner cylinder 7. This complex flow pattern can thoroughly mix the molten zinc, ensuring a uniform distribution of various components in the molten zinc, effectively avoiding uneven zinc concentration, and thus ensuring consistent thickness and quality of the galvanized layer in all parts of the spring, reducing problems such as localized missed plating or excessive differences in zinc layer thickness.

[0039] like Figure 3 As shown, in some embodiments, the positioning posts 9 are arranged in two rings: one for vertically mounting the springs, and the other for isolating the space of the inner cylinder 7, facilitating the placement of more springs within the inner cylinder 7. The positioning posts 9 isolate the space of the inner cylinder 7, helping to utilize the space more efficiently and increasing the number of springs that can be placed. By rationally planning the spacing and layout between the two rings of positioning posts 9, the springs can be arranged compactly, making full use of the radial and axial space of the inner cylinder 7. Without changing the overall dimensions of the device, more springs can be galvanized at once, increasing the processing capacity per batch, reducing the number of batches, improving production efficiency, and reducing production costs.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
