[0002] In the heat treatment industry, especially in the quenching heat treatment of automotive stabilizer bars, stabilizer bars that have been isothermally bent are typically quenched to achieve the required hardness. Currently, different models or types of automobiles install stabilizer bars with different specifications, resulting in variations in the diameter, length, and shape of the stabilizer bars. This necessitates the use of various quenching oil tanks with different structures and sizes to match them, as a single quenching oil tank cannot accommodate multiple specifications of automotive stabilizer bars. Utility Model Content

[0003] The main purpose of this invention is to propose a quenching oil tank, which aims to solve the problem that existing quenching oil tanks cannot be adapted to various specifications of automotive stabilizer bars.

[0004] To achieve the above objectives, this utility model proposes a quenching oil tank, comprising a conveying mechanism, a loading mechanism, a unloading mechanism, and a tank body capable of containing oil. The tank body has loading and unloading stations spaced apart in the x-direction. The conveying mechanism is located within the tank body and between the loading and unloading mechanisms. The conveying mechanism includes two conveying components spaced apart in the y-direction. The two conveying components can be close to or far from each other. Each of the two conveying components includes a conveying part for supporting and fixing a stabilizing rod. The conveying parts of the two conveying components are synchronously moved, and their movement paths extend from the loading station to the unloading station. The loading mechanism includes a loading part for placing the stabilizing rod onto the conveying part, and the unloading mechanism includes a unloading part for removing the stabilizing rod from the conveying part.

[0005] According to some embodiments of the present invention, both of the conveying components have a placement groove formed on their conveying sections for placing and fixing materials.

[0006] According to some embodiments of the present invention, the discharge side wall of the placement trough includes a first wall section and a second wall section connected sequentially from the bottom of the trough to the opening of the trough. The first wall section has a limiting wall that can cooperate with the receiving side wall of the placement trough to support and restrict the movement of the stabilizing rod. The second wall section is inclined towards the discharge side.

[0007] According to some embodiments of the present invention, the material conveying assembly further includes a first chain and two first transmission wheels that rotate about an axis extending along the y-direction. The two first transmission wheels are respectively arranged corresponding to the loading station and the unloading station. The two first transmission wheels are connected through the first chain. The material conveying part is provided in multiple ways, and the multiple material conveying parts are arranged at intervals along the length direction of the first chain.

[0008] According to some embodiments of the present invention, the feeding mechanism further includes a motor, a screw, and two connecting parts. The screw is driven by the motor to rotate around an axis extending in the y-direction. The screw has two threads in opposite directions. The two connecting parts are respectively connected to the screw through the two threads. The two feeding assemblies are respectively connected to the two connecting parts.

[0009] According to some embodiments of the present invention, the feeding mechanism includes two feeding components spaced apart in the y-direction. The two feeding components are arranged in a one-to-one correspondence with the two conveying components. Each feeding component includes a feeding part, a second chain part, and two second transmission wheels that can be arranged in forward and reverse directions. The two second transmission wheels rotate around an axis extending in the y-direction. The two second transmission wheels are connected through the second chain part. The feeding part is connected to the second chain part. The feeding part is arranged to reciprocate between the two second transmission wheels. The end of the movement path of the feeding part is located close to the conveying part corresponding to the conveying component.

[0010] According to some embodiments of the present invention, the feeding mechanism further includes a transmission rod, the two ends of which are respectively connected to the second chain portions of the two feeding components. The feeding portions of the two feeding components are all located in the middle of the transmission rod, and the two feeding portions are movably and adjustablely mounted on the transmission rod.

[0011] According to some embodiments of the present invention, the feeding mechanism includes two feeding components spaced apart in the y-direction. The two feeding components are arranged in a one-to-one correspondence with the two conveying components. Each feeding component includes a feeding part, a third chain part, and two third transmission wheels that rotate about an axis extending along the y-direction. The two third transmission wheels are connected through the third chain part. One of the third transmission wheels is located close to the first transmission wheel corresponding to the conveying component. There are multiple feeding parts, and the multiple feeding parts are spaced apart in the length direction of the third chain part.

[0012] According to some embodiments of the present invention, the feeding mechanism further includes two unloading sections that are arranged one-to-one with the two feeding components. The unloading sections are arranged close to the third transmission wheel away from the feeding component. The unloading section includes a storage section and a guiding section. A storage groove for temporarily storing the stabilizing rod is formed on the storage section. The guiding section has a guiding surface that guides the stabilizing rod corresponding to the feeding component into the storage groove.

[0013] According to some embodiments of the present invention, the third transmission wheel on the unloading assembly near the conveying assembly is connected to the two first transmission wheels corresponding to the conveying assembly through the first chain portion.

[0014] This utility model has at least the following beneficial effects:

[0015] In this invention, the distance between two conveying components is adjusted by moving them closer or further apart according to the length of the stabilizing rod to be quenched. Then, the loading section places the stabilizing rod onto the two conveying sections. Since the conveying mechanism is located within the tank, which can hold oil, the quenching process can be performed on the stabilizing rod as it moves from the loading station to the unloading station. Simultaneously, the stability of the stabilizing rod is ensured by the joint support of the two conveying sections. After the two conveying sections reach the unloading station, the unloading section removes the stabilizing rod from the conveying section for transfer to the next process. This invention, by adjusting the distance between the two conveying components by moving them closer or further apart, allows the conveying mechanism to adapt to stabilizing rods of different lengths, thus enabling the quenching oil tank of this invention to quench stabilizing rods of various specifications.

[0029] This utility model provides a quenching oil tank. Figures 1 to 7 This invention provides a specific embodiment of a quenching oil tank.

[0030] like Figures 1 to 7 As shown, this embodiment of the utility model provides a quenching oil tank 100, including a conveying mechanism 1, a loading mechanism 2, a unloading mechanism 3, and a tank 4 for containing oil. The tank 4 has loading stations 41 and unloading stations 42 spaced apart in the x-direction. The conveying mechanism 1 is located inside the tank 4 and between the loading mechanism 2 and the unloading mechanism 3. The conveying mechanism 1 includes two conveying components 11 spaced apart in the y-direction, and the two conveying components 11 can abut against each other. Whether close to or far from each other, both of the conveying assemblies 11 include a conveying section 111 for supporting and fixing the stabilizing rod 200. The conveying sections 111 of the two conveying assemblies 11 are moved synchronously, and the moving paths of both extend from the loading station 41 to the unloading station 42. The loading mechanism 2 includes a loading section 211 for placing the stabilizing rod 200 onto the conveying section 111, and the unloading mechanism 3 includes an unloading section 311 for removing the stabilizing rod 200 from the conveying section 111.

[0031] In this invention, the two conveying components 11 are first driven to move closer or further apart according to the length of the stabilizing rod 200 to be quenched, so as to adjust the distance between the two conveying components 11. Then, the loading part 211 places the stabilizing rod 200 to be quenched onto the two conveying parts 111. Since the conveying mechanism 1 is located in the tank 4 and the tank 4 can hold oil, the quenching step can be performed on the stabilizing rod 200 during the process of moving from the loading station 41 to the unloading station 42. At the same time, the stability of the stabilizing rod 200 can be ensured by the joint support of the two conveying parts 111. After the two conveying parts 111 move to the unloading station 42, the unloading part 311 removes the stabilizing rod 200 from the conveying part 111 so that the stabilizing rod 200 can be transferred to the next process. This invention adjusts the distance between the two conveying components 11 by moving them closer or further apart, thereby enabling the conveying mechanism 1 to adapt to stabilizing rods 200 of different lengths. This allows the quenching oil tank 100 of this invention to quench stabilizing rods 200 of various specifications.

[0032] It should be noted that since the stabilizer bar 200 generates a large amount of oil fumes during the quenching process, the oil fumes in the tank 4 can be discharged by setting exhaust mechanisms 5 at the loading station 41 and the unloading station 42 respectively.

[0033] The specific manner in which the conveying section 111 supports and fixes the stabilizing rod 200 is not limited; for example, in some embodiments, such as... Figure 4 As shown, both conveying assemblies 11 have placement grooves 1111 formed on their conveying sections 111 for placing and fixing materials. With this configuration, by providing the placement grooves 1111 in the conveying sections 111 for placing and fixing the stabilizing rods 200, stabilizing rods 200 of various diameters and cross-sectional shapes can be placed in the placement grooves 1111. Compared to the traditional method of fixing the stabilizing rods 200 using positioning fixtures, the conveying mechanism 1 can accommodate stabilizing rods 200 of different diameters and shapes.

[0034] It should be noted that both the feeding part 211 and the unloading part 311 have groove structures to accommodate stabilizing rods 200 of different diameters and shapes.

[0035] Furthermore, in some embodiments, such as Figure 4 As shown, the discharge side wall of the placement trough 1111 includes a first wall section 11111 and a second wall section 11112 connected sequentially from the bottom to the opening. The first wall section 11111 has a limiting wall that can cooperate with the receiving side wall of the placement trough 1111 to support and restrict the movement of the stabilizing rod 200. The second wall section 11112 is inclined towards the discharge side. This configuration, with the second wall section 11112 inclined towards the discharge side, allows the stabilizing rod 200 on the conveying section 111 to roll along the second wall section 11112 to the unloading section 311, eliminating the need for additional gripping components in the unloading section 311 and simplifying the structure.

[0036] The specific structure of the material conveying mechanism 1 is not limited, as long as the movement path of the two material conveying parts 111 extends from the loading station 41 to the unloading station 42. For example, in some embodiments, such as Figure 4 and Figure 6 As shown, the material conveying assembly 11 further includes a first chain 112 and two first transmission wheels 113 that rotate about an axis extending along the y-direction. The two first transmission wheels 113 are respectively arranged corresponding to the loading station 41 and the unloading station 42. The two first transmission wheels 113 are connected by the first chain 112. Multiple material conveying sections 111 are provided, and the multiple material conveying sections 111 are spaced apart along the length of the first chain 112. By providing multiple material conveying sections 111, the quenching oil tank 100 can simultaneously quench multiple stabilizing rods 200, greatly improving the quenching efficiency.

[0037] Preferably, in some embodiments, such as Figure 2 and Figure 6As shown, the feeding mechanism 1 further includes a motor 12, a screw 13, and two connecting parts 14. The screw 13 is driven by the motor 12 to rotate around an axis extending in the y-direction. The screw 13 has two threads with opposite directions. The two connecting parts 14 are respectively connected to the screw 13 through the two threads. The two feeding assemblies 11 are respectively connected to the two connecting parts 14. With this configuration, since the connecting parts 14 are connected to the screw 13 through threads, and the two threads are in opposite directions, when the motor 12 drives the screw 13 to rotate, the two connecting parts 14 move in opposite directions. That is, the two connecting parts 14 can move closer to each other or further away from each other, causing the two feeding assemblies 11 to move closer to each other or further away from each other.

[0038] To improve the stability of the movement of the feeding assembly 11, in some embodiments, such as Figure 2 and Figure 6 As shown, the feeding mechanism 1 further includes a guide structure 15 and two support sliders 16. The guide structure 15 extends along the y-direction, and the two support sliders 16 are movably mounted on the guide structure 15. The two feeding assemblies 11 are respectively connected to the two support sliders 16. This arrangement ensures the stability of the feeding assembly 11's movement by having the connecting part 14 and the support sliders 16 jointly support it.

[0039] The specific structure of the feeding mechanism 2 is not limited, as long as the feeding part 211 of the feeding mechanism 2 can place the stabilizing rod 200 onto the conveying part 111. For example, in some embodiments, such as... Figure 2 and Figure 3As shown, the feeding mechanism 2 includes two feeding components 21 spaced apart in the y-direction. The two feeding components 21 are correspondingly arranged with the two conveying components 11. Each feeding component 21 includes a feeding part 211, a second chain part 212, and two second transmission wheels 213 that can be arranged in both forward and reverse directions. The two second transmission wheels 213 rotate around an axis extending in the y-direction. The two second transmission wheels 213 are connected through the second chain part 212. The feeding part 211 is connected to the second chain part 212. The feeding part 211 is arranged to reciprocate between the two second transmission wheels 213. The end of the movement path of the feeding part 211 is located close to the conveying part 111 corresponding to the conveying component 11. Since the conveying mechanism 1 immerses the stabilizing rod 200 in oil to complete quenching while conveying the stabilizing rod 200, it needs to ensure that the stabilizing rod 200 has sufficient time to be immersed in the oil. Therefore, the moving speed of the conveying part 111 is relatively slow. The task of the loading mechanism 2 is to quickly place the stabilizing rod 200 onto the conveying part 111 of the conveying mechanism 1 within a specified time. By setting one loading part 211 on the second chain part 212 of each of the two loading components 21, the loading requirements of the stabilizing rod 200 can be met. Moreover, the two loading parts 211 jointly support the stabilizing rod 200 to ensure the moving stability of the stabilizing rod 200. It is not necessary to arrange multiple loading parts 211 at intervals on the second chain part 212. On the one hand, it reduces production costs, and on the other hand, it reduces the area occupied by the loading mechanism 2.

[0040] Furthermore, in some embodiments, such as Figure 7 As shown, the feeding mechanism 2 further includes a transmission rod 22. Both ends of the transmission rod 22 are connected to the second chain portions 212 of the two feeding components 21, respectively. The feeding portions 211 of both feeding components 21 are located in the middle of the transmission rod 22, and the two feeding portions 211 are movably and adjustablely mounted on the transmission rod 22. This configuration, where the feeding portions 211 are connected to the second chain portions 212 via the transmission rod 22, improves the movement stability of the feeding portions 211. The movability and adjustability of the two feeding portions 211 on the transmission rod 22 allows for adjustment of the distance between them, accommodating stabilizing rods 200 of different lengths.

[0041] Furthermore, in some embodiments, the transmission rod 22 is provided with a scale, and the projected positions of the two feeding parts 211 are located between the two conveying assemblies 11. Since this invention mainly adapts the length of the stabilizing rod 200 by adjusting the distance between the feeding parts 111 of the two conveying assemblies 11, and sets the distance between the two feeding parts 211 to be smaller than the distance between the conveying assemblies 11, the two feeding parts 211 can always support the stabilizing rod 200.

[0042] The specific structure of the feeding mechanism 3 is not limited, as long as the feeding part 311 can receive the stabilizing rod 200 on the conveying part 111. For example, in some embodiments, such as... Figure 2 , Figure 4 and Figure 5 As shown, the feeding mechanism 3 includes two feeding assemblies 31 spaced apart in the y-direction. Each feeding assembly 31 corresponds to one of the two conveying assemblies 11. Each feeding assembly 31 includes a feeding section 311, a third chain section 312, and two third drive wheels 313 rotating about an axis extending in the y-direction. The two third drive wheels 313 are connected by the third chain section 312. One of the third drive wheels 313 is positioned close to the first drive wheel 113 corresponding to the conveying assembly 11. Multiple feeding sections 311 are provided, spaced apart along the length of the third chain section 312. Since the conveying mechanism 1 can simultaneously transport multiple stabilizing rods 200, the spaced arrangement of multiple feeding sections 311 on the third chain section 312 ensures that each stabilizing rod 200 can be received.

[0043] Specifically, in some embodiments, the plurality of conveying sections 111 are evenly distributed along the length of the first chain section 112, and the plurality of unloading sections 311 are evenly distributed along the length of the third chain section 312, with the spacing between two adjacent conveying sections 111 and the spacing between two adjacent unloading sections 311 being the same. This arrangement ensures that each stabilizing rod 200 conveyed by the conveying section 111 can be received by the unloading section 311.

[0044] Since the unloading part 311 is located on the third chain part 312, and the third transmission wheel 313 always rotates in the forward direction, when the unloading part 311 moves to the unloading station 42, the stabilizing rod 200 is simultaneously lifted and transferred to the next process. If the next process malfunctions and cannot temporarily transfer the stabilizing rod 200, the stabilizing rod 200 will directly detach from the unloading part 311 under the action of gravity during the movement of the unloading part 311 around the third transmission wheel 313. Therefore, in some embodiments, such as... Figure 5As shown, the feeding mechanism 3 also includes two unloading sections 32 corresponding to the two feeding components 31. The unloading sections 32 are located near the third transmission wheel 313 away from the feeding component 11. Each unloading section 32 includes a storage section 321 and a guide section 322. The storage section 321 has a storage groove 3211 for temporarily storing the stabilizing rod 200. The guide section 322 has a guide surface that guides the stabilizing rod 200 corresponding to the feeding component 31 into the storage groove 3211. This arrangement allows the stabilizing rod 200 to be temporarily stored in the storage groove 3211 of the unloading section 32, preventing it from directly detaching from the feeding section 311 and falling onto the tank 4, thus avoiding collision with other components of the quenching oil tank 100.

[0045] Specifically, in some embodiments, such as Figure 5 As shown, the feeding mechanism 3 also includes a cylinder 33, the telescopic rod of which is rotatably connected to the unloading part 32. This configuration allows the angle of the unloading part 32 to be adjusted under the drive of the cylinder 33, making it easier for the material handling component in the next process to remove the stabilizing rod 200 from the storage trough 3211.

[0046] Furthermore, in some embodiments, such as Figure 2 and Figure 4 As shown, the third transmission wheel 313 on the unloading assembly 31, near the conveying assembly 11, is connected to the two first transmission wheels 113 corresponding to the conveying assembly 11 via the first chain portion 112. With this configuration, when the first transmission wheel 113 rotates, it drives the third transmission wheel 313 to rotate, which in turn drives the other third transmission wheel 313 to rotate. By connecting one of the third transmission wheels 313 to the first transmission wheel 113, the unloading mechanism 3 does not require a separate drive component, simplifying the structure and reducing production costs.

[0047] The oil in the tank 4 will increase in temperature after prolonged use, which will lead to a decrease in the quenching effect. Therefore, in some embodiments, such as Figure 1As shown, the tank 4 is provided with an oil inlet 43 and an oil outlet 44. The oil inlet 43 is located at the lower part of the tank 4 and is set near the loading station 41. The oil outlet 44 is located at the upper part of the tank 4 and is set near the unloading station 42. Since the quenching of the stabilizer bar 200 begins at the loading station 41, the oil temperature at the loading station 41 rises. The conveying part 111 moves from the loading station 41 to the unloading station 42, causing the hotter oil to move to the unloading station 42. The hotter oil is located at the upper part of the tank 4 at the unloading station 42. The hotter oil is pumped away from the oil outlet 44 by the oil pump. At the same time, cooler oil is injected into the tank 4 from the oil inlet 43, so that the oil at the loading station 41 in the tank 4 is always kept at a low temperature to ensure the quenching effect of the oil.

[0048] Specifically, such as Figure 1 As shown, there are two oil outlets 44, located at the upper and lower parts of the tank 4 respectively, and both are positioned close to the unloading station 42. By increasing the number of oil outlets 44, the discharge efficiency of high-temperature oil is improved.

[0049] Furthermore, in some embodiments, the oil outlet 44 is connected to the inlet of the heat exchanger, and the oil inlet 43 is connected to the outlet of the heat exchanger. The oil with a higher temperature is cooled by the heat exchanger and then input into the tank 4 through the oil inlet 43, so that the oil is in a circulating state and there is no need to input oil from the outside.

[0050] Since the oil temperature will continuously rise when the stabilizer bar 200 is quenched at the loading station 41, in order to meet the quenching process requirements of the stabilizer bar 200, in some embodiments, a stirring device is provided in the tank 4. The stirring device is set close to the loading station 41. By stirring the oil at the loading station 41, the lower temperature oil input from the oil inlet 43 can be quickly mixed with the high temperature oil in the quenching area, thereby achieving rapid cooling of the oil in the quenching area.

[0051] In some embodiments, the tank 4 is further equipped with a temperature detection device and a liquid level detection device, both of which are electrically connected to the oil pump via a controller. When the liquid level detection device detects that the oil level in the tank 4 is lower than a set level, it can control the oil pump to input oil from the outside into the tank 4. When the temperature detection device detects that the oil temperature is higher than a set temperature, it can control the oil pump to pump away the oil with the higher temperature and cool it through the heat exchanger before returning it to the tank 4, so that the oil temperature in the tank 4 is maintained within the set temperature range.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
