[0002] Leaf springs are the most widely used elastic elements in automobile suspensions. They accelerate the attenuation of frame and body vibrations to improve the ride smoothness of the car. When the impact force of the road on the wheels is transmitted, the steel plate deforms to play a role in buffering and vibration reduction. Leaf springs that have undergone chemical heat treatment often need to be quenched and cooled, that is, in a high-temperature red-hot state, the austenite structure is quickly immersed in oil with a suitable cooling rate to achieve the required comprehensive mechanical properties of the parts.

[0003] At present, the quenching agent or quenching oil inside the leaf spring quenching oil tank is generally in a static state, which leads to uneven temperature distribution during the quenching process. This uneven temperature distribution will directly affect the quenching effect, making it impossible for the properties such as hardness and toughness of the leaf spring to achieve the expected uniformity. In addition, static quenching oil is also prone to cause impurities and sediments to accumulate inside the oil tank, which not only affects the cleanliness and service life of the quenching oil, but may also cause pollution to the leaf spring, further affecting its quality.

[0004] Therefore, it is very necessary to invent a quenching oil tank for producing leaf springs. Utility Model Content

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a quenching oil tank for leaf spring production, comprising a quenching oil tank 1, a cleaning door 2, a sedimentation tank 3 and a flow rate uniformity mechanism 4, wherein the cleaning door 2 is sealed and fixedly installed on the quenching oil tank 1, and the sedimentation tank 3 is provided on the quenching oil tank 1 and the cleaning door 2; the flow rate uniformity mechanism 4 is installed on the quenching oil tank 1.

[0022] The flow rate uniformity mechanism 4 includes a swing shaft 41, a swing plate 42, a swing gear 43, a driving rack 44, a mounting seat 45 and a reciprocating hydraulic cylinder 46. The swing shaft 41 is rotatably mounted inside the quenching oil tank 1, and the swing plate 42 is fixedly mounted on the swing shaft 41; either end of the swing shaft 41 rotates through the quenching oil tank 1 and is fixedly connected to the swing gear 43 outside it, and the swing gear 43 is meshed with the driving rack 44, one end of the driving rack 44 is fixedly connected to the output end of the reciprocating hydraulic cylinder 46 fixedly mounted on the mounting seat 45, and the other end of the driving rack 44 slides through the mounting seat 45, and the two mounting seats 45 are fixedly mounted on the quenching oil tank 1. The flow rate uniformity mechanism 4 not only improves the fluidity of the quenching oil, but also effectively solves the problem of uneven temperature distribution, thereby improving the quenching effect and product quality.

[0023] Embodiment 1:

[0024] Specifically, the sedimentation groove 3 provided on the quenching oil tank 1 is a composite groove consisting of a triangular groove and a rectangular groove. The triangular groove is provided at the inner bottom of the quenching oil tank 1. The selection of this position is based on the principle of gravity sedimentation, so that impurities and sediments generated during the quenching process can naturally settle into the triangular groove. The rectangular grooves are provided on both sides of the interior of the quenching oil tank 1 and the inner side of the cleaning door 2. This layout not only expands the sedimentation area and improves the sedimentation efficiency, but also ensures that impurities and sediments during the entire quenching process can be effectively collected.

[0025] Specifically, the swing shaft 41 and the swing plate 42 are located above the triangular groove of the sedimentation tank 3 and below the quenching oil tank 1. This layout enables the swing plate 42 to not only effectively promote the circulation of the quenching oil in the quenching oil tank 1 and improve the uniformity of the quenching oil during the swinging process, but also to use the force generated by the swinging to push the impurities suspended in the oil to the sedimentation tank 3, especially the position of the triangular groove, thereby further enhancing the sedimentation effect. The swing plate 42 is designed as a diamond plate. This shape not only ensures the strength of the swing plate 42, but also makes it have better fluidity and flexibility during the swinging process. The design of the diamond plate also allows the spacing between the swing plates 42 to allow each other to swing, avoiding mutual interference and obstruction during the swinging process, and ensuring the cooperative working effect of the swing shaft 41 and the swing plate 42.

[0026] Specifically, the swing gear 43 is located outside the quenching oil tank 1. This layout allows the swing gear 43 to be away from the high temperature environment inside the quenching oil tank 1, ensuring its normal operation and long service life. At the same time, many swing gears 43 are meshed and connected with the driving rack 44. This design allows all the swing gears 43 to rotate synchronously when the driving rack 44 is driven by the reciprocating hydraulic cylinder 46 to reciprocate.

[0027] Specifically, the mounting seat 45 is a "U"-shaped structure, wherein a through hole is provided on one of the mounting seats 45 to allow the shaft end of the driving rack 44 to slide through, and the reciprocating hydraulic cylinder 46 is fixedly installed on the outer side of the other mounting seat 45, and the reciprocating hydraulic cylinder 46 is used to drive the driving rack 44 to reciprocate. The two ends of the driving rack 44 are integrally provided with round shaft ends, which not only enhances the strength and stability of the driving rack 44, but also makes it smoother during movement, reducing friction and wear. The round shaft end can also easily pass through the through hole on the mounting seat 45 to achieve the connection between the driving rack 44 and the mounting seat 45.

[0028] Embodiment 2:

[0029] First, the quenching oil tank 1 is filled with quenching oil, and after the preparation work is completed, the leaf spring workpiece is placed in the quenching oil tank 1 for quenching. At this time, the reciprocating hydraulic cylinder 46 starts to work, driving the drive rack 44 connected to its output end to reciprocate.

[0030] The reciprocating motion of the driving rack 44 drives all the swing gears 43 to rotate synchronously through the meshing relationship. Since the swing gear 43 is fixedly connected to the swing shaft 41, the rotation of the swing gear 43 will be converted into the rotational motion of the swing shaft 41, thereby driving the swing plate 42 fixed on the swing shaft 41 to swing.

[0031] When the swing plate 42 swings inside the quenching oil tank 1, its diamond design makes the swinging process smoother, and the spacing between the swing plates 42 allows each other to swing, avoiding mutual interference. This swinging motion effectively promotes the circulation of the quenching oil in the quenching oil tank 1, improves the uniformity and fluidity of the quenching oil, and thus solves the problem of uneven temperature distribution caused by traditional static quenching oil.

[0032] At the same time, the swing of the swing plate 42 also generates a certain impact force, pushing the impurities suspended in the quenching oil to the precipitation tank 3. In particular, when the swing plate 42 is close to the triangular groove of the precipitation tank 3, its impact force can more effectively push the impurities into the groove, thereby enhancing the precipitation effect.

[0033] On the other hand, the sedimentation tank 3 on the cleaning door 2 also plays a role in collecting impurities. During the quenching process, some impurities and sediments will be brought to the vicinity of the cleaning door 2 by the flow of the quenching oil, and finally collected in the sedimentation tank 3 inside the cleaning door 2.

[0034] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
