Description

Technical Field

[0001] This utility model relates to the field of steel structure production technology, specifically to a heat treatment equipment for producing brittle-resistant steel structure components. Background Technology

[0002] The heat treatment process for steel structural components is a complex and delicate process. By controlling the parameters of heating, holding, and cooling, the performance of steel can be significantly improved to meet specific application requirements, such as hardness, strength, toughness, and wear resistance. The heat treatment process for steel structural components typically involves heating, holding, and cooling. Throughout the entire heat treatment process, it is necessary to strictly control key factors such as heating temperature, holding time, cooling rate, and subsequent processing parameters to ensure that the steel structural components obtain the required microstructure and properties.

[0003] Referring to Chinese Patent Publication No. CN220183345U, with the publication date of December 15, 2023, a heat treatment equipment for producing steel structural components is disclosed. This heat treatment equipment for producing steel structural components uses a displacement motor to drive a moving block to the right. The moving block, through a clamping mechanism, drives the steel structural component to the outside of the heat treatment furnace. At this time, the rotating gear just contacts the rack, causing the rotating shaft to rotate 90°. The rotating shaft, through the clamping mechanism, drives the steel structural component to rotate 90°. Thus, the steel structural component can be placed on a bracket inside the heat treatment furnace or taken out of the heat treatment furnace. There is no need for manual use of pliers to take out or put into the heat treatment furnace, avoiding the risk of workers being burned by the high temperature of the heat treatment furnace.

[0004] However, in the process of using this utility model, there are many components used to clamp the steel structure, which is quite troublesome. Also, it is not convenient to cool the steel structure after heating it. Therefore, there is still room for further improvement.

[0005] Therefore, we propose a heat treatment equipment for the production of brittle-resistant steel structural components to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a heat treatment equipment for the production of brittle-resistant steel structural components, in order to solve the problems mentioned in the background art. Currently, the utility model requires a large number of components when clamping steel structural components, which is cumbersome. Furthermore, it is inconvenient to cool the steel structural components after heating. Therefore, there is still room for further improvement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment device for producing brittle-resistant steel structural components, comprising:

[0008] A support platform is installed above the work plate via a support structure. The support structure is composed of a connecting shaft, a first support member, a connecting plate, and a second support member. The connecting shaft is fixedly connected to the output shaft of a stepper motor, and the stepper motor is located on the lower side of the work plate. The connecting shaft passes through the work plate.

[0009] Also includes:

[0010] The support platform is equipped with a clamping mechanism inside;

[0011] A cooling box, the interior of which is equipped with a cooling mechanism.

[0012] Preferably, a first support member is rotatably connected to the outer side of the connecting shaft, and the lower side of the first support member is fixedly connected to the working plate, and a connecting plate is provided on the outer side of the connecting shaft.

[0013] Preferably, the connecting plates are arranged in an array, and the lower side of the connecting plates is fixedly connected to the second support member, and the second support member is rotatably connected to the connecting shaft.

[0014] Preferably, the connecting plate is fixedly connected to the support platform, and the connecting plate, support platform, clamping plate, bidirectional threaded rod and rotating rod correspond one-to-one.

[0015] Preferably, the clamping mechanism is composed of a clamping plate, a bidirectional threaded rod, a rotating rod, and a drain outlet, and the clamping plate is slidably connected to the support platform, and the clamping plate is symmetrical about the vertical central axis of the support platform.

[0016] Preferably, the clamping plate is threadedly connected to the bidirectional threaded rod, the bidirectional threaded rod is rotatably connected to the support platform, and the bidirectional threaded rod is fixedly connected to the rotating rod.

[0017] Preferably, a heat treatment furnace is provided on the right side of the work plate, and a cooling box is provided on the left side of the work plate. A water tank is provided on the side of the cooling box, and a water pump is provided on the upper side of the water tank.

The water pump is fixedly connected to the water distribution plate, and the water distribution plate is located on the inner upper side of the working plate. The water distribution plate has water outlets on its lower side, and the water outlets are arranged in an array.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the heat treatment equipment for producing brittle-resistant steel structural components, the first support and the second support can reduce the force of the support table on the connecting shaft, thereby making it easier for the support table to move the steel structural component into the heat treatment furnace or cooling box. The bidirectional threaded rod rotates, causing the clamping plate to move inside the support table, thereby clamping the steel structural component and facilitating heat treatment. Water will be discharged from the water outlet and fall on the steel structural component, which will facilitate the cooling of the steel structural component and thus accelerate the heat treatment efficiency.

[0020] 1. It is equipped with a stepper motor, a connecting shaft and a first support component. The stepper motor is located on the lower side of the work plate. The stepper motor can rotate the connecting shaft, which makes it convenient for the connecting plate to rotate with the support platform.

[0021] 2. It is equipped with a first support member, a second support member, and a support platform. The first support member and the second support member are rotatably connected to the outside of the connecting shaft. The first support member and the second support member can reduce the force exerted by the support platform on the connecting shaft, thereby facilitating the movement of the support platform with the steel structure into the heat treatment furnace or cooling box.

[0022] 3. It is equipped with a clamping plate, a double-threaded rod and a rotating rod. When the steel structure is placed inside the support platform, any round rod can be inserted into the rotating rod to make the double-threaded rod rotate, thereby moving the clamping plate inside the support platform and clamping the steel structure for easy heat treatment.

[0023] 4. It is equipped with a cooling tank, a water tank and a water pump. The water tank has a water inlet on the upper side, through which water can be added to the water tank for easy cooling.

[0024] 5. Equipped with a water pump, a water distribution plate, and a water outlet, the water pump draws water from the tank and delivers it to the water distribution plate. The water then exits through the water outlet and falls onto the steel structure, facilitating cooling of the steel structure and thus accelerating heat treatment efficiency.

[0031] 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.

[0032] It should be noted that the clamping mechanism is composed of a clamping plate 8, a two-way threaded rod 9, a rotating rod 10 and a drain outlet 11. The clamping mechanism can clamp the steel structure on the upper side of the support platform 7. The cooling mechanism is composed of a water tank 14, a water pump 15 and a water distribution plate 16. The cooling mechanism can quickly cool the steel structure, which can facilitate the acceleration of the heat treatment process.

[0033] like Figure 1 As shown, a connecting plate 5 is provided on the outer side of the connecting shaft 3, and a support platform 7 is provided on the outer side of the connecting plate 5. The support platforms 7 are arranged in an array. One support platform 7 is located inside the heat treatment furnace 12, one support platform 7 is located inside the cooling box 13, and another support platform 7 is located on the outer side of the working plate 1. In actual operation, the support platform 7 inside the heat treatment furnace 12 is used for heating treatment, while the support platform 7 inside the cooling box 13 is used for cooling treatment. Steel structural components are provided on the inner side of both of these support platforms 7, and no steel structural components are placed on the remaining support platform 7.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a steel structure is placed on the upper side of one of the support platforms 7. Any circular rod is inserted into the rotating rod 10. Rotating the rotating rod 10 will cause the bidirectional threaded rod 9 to rotate. Since the bidirectional threaded rod 9 is threadedly connected to the clamping plate 8, the rotating bidirectional threaded rod 9 can cause the clamping plate 8 to move. At this time, the clamping plate 8 will move inside the support platform 7, thereby clamping the steel structure. Then, the stepper motor 2 is started, which will cause the connecting shaft 3 to rotate. Due to the characteristics of the stepper motor 2, the support platform 7 will move into the heat treatment furnace 12 for heat treatment.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, after the steel structural components inside the heat treatment furnace 12 have been heat-treated, steel structural components are added to the sequential support platform 7. Then, the stepper motor 2 is started again. At this time, the support platform 7 inside the heat treatment furnace 12 will move into the cooling box 13, and the steel structural components inside the sequential support platform 7 will move into the heat treatment furnace 12 for heating. At this time, the support platform 7 located inside the cooling box 13 will move to the next sequence to remove or place the cooled steel structural components. After the heated steel structural components are moved into the cooling box 13, the water pump 15 is started. The water pump 15 will draw water from the water tank 14 and then transport it to the water distribution plate 16 through the water pipe. At this time, the water will be discharged from the water distribution port 17 and fall on the steel structural components to facilitate cooling of the steel structural components, thereby accelerating the heat treatment efficiency. This cycle is repeated to heat treat the steel structural components. In addition, a drainage hole is provided on the lower side of the interior of the cooling box 13 for easy drainage.

[0036] It should be noted that the stepper motor 2 is located on the lower side of the working plate 1. When the stepper motor 2 is working, it can rotate the connecting shaft 3, which makes it easier for the connecting plate 5 to rotate the support platform 7. In addition, the outer side of the connecting shaft 3 is rotatably connected to the first support member 4 and the second support member 6. When the steel structure is placed inside the support platform 7, the second support member 6 will support the connecting plate 5 and lower the center of gravity brought by the support platform 7. The first support member 4 will also support the connecting shaft 3 to prevent the connecting shaft 3 from bending, thereby making it easier for the support platform 7 to move the steel structure into the heat treatment furnace 12 or the cooling box 13.

All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0038] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
