Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a quenching device for spring processing. Background Technique

[0002] Quenching for spring processing is a heat treatment process used to improve the mechanical properties of springs, such as strength, hardness, and toughness. Through quenching treatment, springs can obtain higher strength and hardness, thereby improving their load-bearing capacity and service life.

[0003] Traditional quenching processes usually use oil as the cooling medium. When a high-temperature spring is immersed in the oil, it will cool rapidly and generate a large amount of oil waste gas. These waste gases contain various harmful substances, such as particulate matter, volatile organic compounds, etc. If directly discharged into the environment, it will not only pollute the atmosphere but also may pose a hazard to the health of operators. In addition, during the quenching process, iron filings and impurities will be generated on the surface of the spring. If these impurities are not cleaned in time, they will mix into the quenching medium, thereby affecting the subsequent quenching effect and quality of the spring. Content of the Utility Model

[0004] To solve at least to some extent the above technical problems, the utility model provides a quenching device for spring processing.

[0005] The utility model is realized by the following technical solutions: A quenching device for spring processing includes a quenching pool. The outer surface of the quenching pool is fixedly connected with a purification box. An air extraction component is arranged on the upper surface of the purification box. A discharge pipe is fixedly connected to the outer surface of the purification box.

[0006] The air extraction component includes an air extraction pump. The bottom of the air extraction pump is fixedly installed on the upper surface of the purification box through bolts. The input end of the air extraction pump is fixedly connected with a bidirectional air pipe. Both ends of the bidirectional air pipe are fixedly connected with main air inlet pipes. Several auxiliary air pipes are fixedly connected to the outer surface of the main air inlet pipes. Both ends of the main air inlet pipes are fixedly connected with support frames. The support frames are fixedly connected to the outer surface of the quenching pool. The output end of the air extraction pump is fixedly connected with a delivery air pipe. The bottom end of the delivery air pipe is arranged inside the purification box.

[0007] Through the above technical solutions, by integrating the purification box with the quenching pool, the generated harmful gases can be processed in a timely and effective manner, avoiding affecting the environment and the health of operators. The design of the air extraction component can efficiently collect the harmful gases generated during the quenching process and send them into the purification box for treatment, ensuring the cleanliness and safety of the working environment. The discharge pipe is fixed on the outer surface of the purification box and is used to discharge the treated clean gas. Through the discharge pipe, the treated clean gas can be smoothly discharged into the environment, avoiding secondary pollution.

[0008] As a further improvement of the above solution, guide grooves are provided on both sides of the inner wall of the quenching pool, and sliding blocks are slidably connected inside the guide grooves.

[0009] As a further improvement of the above solution, a placement basket is fixedly connected to the surface of the sliding block.

[0010] Through the above technical solution, the placement basket can prevent the spring from directly contacting the bottom of the quenching pool during the quenching process, thereby reducing the risk of adhesion between the spring and the pool bottom. By placing the spring in the basket, it can ensure that the quenching medium more evenly surrounds and cools the spring, improving the uniformity and quality of quenching. Moreover, using the placement basket makes it easier to take out the spring after quenching, reducing the operation difficulty and the labor intensity of workers.

[0011] As a further improvement of the above solution, the placement basket is slidably connected to the inner wall of the quenching pool through the sliding block.

[0012] Through the above technical solution, due to the sliding connection between the sliding block and the inner wall of the quenching pool, the placement basket can be easily slid out, facilitating the operator to take and place the quenched spring, and improving work efficiency.

[0013] As a further improvement of the above solution, a number of filtering fine holes are provided on the inner bottom wall of the placement basket.

[0014] Through the above technical solution, through the filtering fine holes, iron filings and impurities generated during the quenching process can be effectively screened out, maintaining the cleanliness of the quenching medium and extending the service life of the medium. Automatically screening out impurities through the filtering fine holes reduces the frequency of manual cleaning of the quenching medium, saving maintenance time and costs.

[0015] As a further improvement of the above solution, lifting handles are fixedly connected to both sides of the upper surface of the placement basket.

[0016] Through the above technical solution, the lifting handles provide convenient gripping points, enabling the operator to more easily lift and move the placement basket, reducing the operation difficulty and the labor intensity of workers.

[0017] As a further improvement of the above solution, a first purification net and a second purification net are respectively arranged on both sides of the inner wall of the purification box.

[0018] Through the above technical solution, by setting the first purification net and the second purification net, multi-stage filtration and purification can be achieved, effectively removing the fume and waste gas generated by the spring during the quenching process and the oil liquid, and improving the purification effect.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] By setting up an air extraction component and a purification box, the utility model can effectively suck the oil exhaust gas generated by the contact between the spring and the oil during the quenching process into the purification box, and conduct double filtration and purification through the first purification net and the second purification net, effectively removing the particulate impurities in the harmful gas, ensuring the cleanliness of the gas discharged into the environment, protecting the working environment of personnel and the atmospheric environment, and when the placement basket is lifted out of the quenching medium, the quenching medium flows back into the quenching pool through the filtering pores, while the iron filings and impurities generated during the quenching process are blocked by the filtering pores and remain in the placement basket. After the operator takes out the placement basket, the iron filings and impurities remaining in the placement basket can be conveniently cleaned up, thereby maintaining the cleanliness of the quenching medium and avoiding the influence of impurities on the subsequent quenching effect.

Specific Embodiment

[0028] Next, in combination with the drawings and specific embodiments, the utility model will be further described. It should be noted that on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0029] Embodiment:

[0030] Please combine Figures 1-5 , A quenching device for spring processing in this embodiment includes a quenching pool 1, a purification box 2 is fixedly connected to the outer surface of the quenching pool 1, an air extraction component 3 is arranged on the upper surface of the purification box 2, and a discharge pipe 4 is fixedly connected to the outer surface of the purification box 2;

[0031] The air extraction assembly 3 includes an air extraction pump 301. The bottom of the air extraction pump 301 is fixedly installed on the upper surface of the purification tank 2 through bolts. The input end of the air extraction pump 301 is fixedly connected with a two-way air pipe 302. Both ends of the two-way air pipe 302 are fixedly connected with main air inlet pipes 303. The outer surface of the main air inlet pipe 303 is fixedly connected with several sub-air pipes 304. Both ends of the main air inlet pipe 303 are fixedly connected with support frames 305. The support frames 305 are fixedly connected to the outer surface of the quenching tank 1. The output end of the air extraction pump 301 is fixedly connected with an air delivery pipe 306. The bottom end of the air delivery pipe 306 is arranged inside the purification tank 2. During the quenching process, the harmful gases generated by the oil liquid and the spring are inhaled into the two-way air pipe 302 through the sub-air pipes 304 and the main air inlet pipes 303. The air extraction pump 301 is started to extract the harmful gases from the two-way air pipe 302 and send them into the purification tank 2 through the air delivery pipe 306. The harmful gases are purified in the purification tank 2 to remove the harmful components and are converted into clean gases. The treated clean gases are discharged into the environment through the discharge pipe 4 to ensure the safety and environmental protection of the working environment.

[0032] Guide grooves 5 are provided on both sides of the inner wall of the quenching tank 1, and sliding blocks 6 are slidably connected inside the guide grooves 5.

[0033] The surface of the sliding block 6 is fixedly connected with a placement basket 7. The placement basket 7 can prevent the spring from directly contacting the bottom of the quenching tank 1 during the quenching process, thereby reducing the risk of the spring sticking to the bottom of the tank. By placing the spring in the basket, it can ensure that the quenching medium more evenly surrounds and cools the spring, improving the uniformity and quality of quenching.

[0034] The placement basket 7 is slidably connected to the inner wall of the quenching tank 1 through the sliding block 6. The spring to be quenched is placed in the placement basket 7, and then the placement basket is pushed into the quenching tank through the sliding block so that it is completely immersed in the quenching medium for quenching treatment. After quenching, cooling is carried out. After cooling, the operator can smoothly take out the placement basket 7 from the quenching medium through the sliding block 6, thereby completing the entire quenching process.

[0035] A number of filtering fine holes 8 are provided on the inner bottom wall of the placement basket 7. During the quenching process, due to the high temperature effect, iron filings and other impurities may be generated on the surface of the spring. These impurities will gradually precipitate to the bottom of the placement basket 7. When the placement basket 7 is lifted out of the quenching medium, the quenching medium flows back into the quenching tank 1 through the filtering fine holes 8, while the iron filings and impurities are blocked by the filtering fine holes 8 and remain in the placement basket 7. The operator can conveniently clean the iron filings and impurities remaining in the placement basket 7 after taking out the placement basket 7, thereby keeping the quenching medium clean.

[0036] On both sides of the upper surface of the placement basket 7, there are fixedly connected lifting handles 9. The lifting handles 9 provide convenient grasping points, enabling the operator to more easily lift and move the placement basket 7, reducing the operation difficulty and the labor intensity of the workers.

[0037] On both sides of the inner wall of the purification box 2, a first purification net 10 and a second purification net 11 are respectively arranged. By setting the first purification net 10 and the second purification net 11, multi-stage filtration and purification can be achieved, effectively removing the fume waste gas generated by the oil during the spring quenching process, improving the purification effect, and preventing the waste gas from being directly discharged, which may affect the working environment of personnel and the atmospheric environment.

[0038] The implementation principle of a quenching device for spring processing in the embodiment of the present application is as follows: The operator places the spring to be quenched into the placement basket 7, and through the sliding block 6, the placement basket 7 is pushed into the quenching pool 1, making it completely immersed in the quenching medium for quenching treatment. After quenching, cooling is carried out. After cooling, the operator can smoothly take out the placement basket 7 from the quenching medium through the sliding block 6, thus completing the entire quenching process. During the quenching process, due to the high temperature effect, iron filings and other impurities may be generated on the surface of the spring, and these impurities will gradually settle to the bottom of the placement basket 7. When the placement basket 7 is lifted out of the quenching medium, the quenching medium flows back into the quenching pool 1 through the filtering pores 8, while the iron filings and impurities are blocked by the filtering pores 8 and remain in the placement basket 7. The operator can conveniently clean the iron filings and impurities remaining in the placement basket 7 after taking out the placement basket 7, thereby maintaining the cleanliness of the quenching medium. The operator holds the lifting handles 9 on both sides of the placement basket 7 with both hands and smoothly lifts or lowers the placement basket 7 through the hand force to complete the operation of taking and placing the spring. During the quenching process, the harmful gas generated by the oil and the spring is inhaled into the two-way air pipe 302 through the secondary air pipe 304 and the main intake pipe 303. The air extraction pump 301 is started to extract the harmful gas from the two-way air pipe 302 and send it into the purification box 2 through the air supply pipe 306. The harmful gas enters the purification box 2 through the air supply pipe 306. The harmful gas first passes through the first purification net 10, and larger particles of impurities are intercepted by the filter net. Subsequently, the gas passes through the second purification net 11, and tiny particles and harmful gases are adsorbed to further purify the medium. The treated clean gas is discharged into the environment through the discharge pipe 4 to ensure the safety and environmental protection of the working environment.

[0039] The above implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the protection scope required by the present utility model.
