Description

Technical Field

[0001] This utility model relates to the field of carburizing furnace technology, and in particular to an integrated structure for cooling treatment of a carburizing furnace. Background Technology

[0002] Carburizing is a key process in the field of metal heat treatment to improve the surface hardness and wear resistance of workpieces. It is widely used in the manufacture of mechanical parts such as gears, bearings, and shafts. The core process is that the workpiece is subjected to the action of a high-temperature carburizing medium in the carburizing furnace, which allows carbon atoms to penetrate into the surface layer to form a hardened layer. After carburizing is completed, the workpiece needs to be cooled before being transferred to subsequent quenching, tempering and other processes.

[0003] To address the aforementioned issues, existing patents have provided solutions. However, the existing carburizing furnace and cooling equipment are independent separate structures, lacking a structure to connect them. This results in workpiece transfer relying on external robotic arms or railcars for cross-equipment transport, thereby reducing the efficiency of workpiece processing.

[0009] Preferably, the snap-fit ​​semi-holes are in contact with the surfaces of the lead screw and the limiting rod, respectively. The connecting rods are welded to the rear sides of the upper rotating baffle and the lower rotating baffle, respectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The cooling mechanism of this application adopts a welded integrated design between the cooling chamber and the cooling furnace, which allows the high-temperature workpiece that has completed carburizing to directly enter the cooling area without being exposed to the air. This avoids the heat loss and oxidation risk of workpiece transfer in traditional split structures. At the same time, the high-temperature fan installed on the top of the cooling furnace accelerates the airflow circulation in the furnace. Combined with the transition buffering effect of the cooling chamber, it effectively avoids workpiece deformation or cracking caused by excessive cooling. The temperature sensor can monitor the temperature in the furnace in real time and provide feedback data, which can be used to adjust the speed of the high-temperature fan or subsequent heat preservation strategy in a timely manner through the PLC controller to ensure the uniformity of the temperature field in the furnace.

[0018] 2. The conveying mechanism of this application uses a lead screw and a limit rod in combination. When the servo motor drives the lead screw to rotate, the conveying plate moves synchronously along the lead screw and limit rod through the threaded sleeve and sliding sleeve, ensuring the precise movement of the conveying plate in the carburizing furnace body, conveying trough, and cooling furnace. At the same time, the guiding effect of the limit rod prevents the conveying plate from rotating, further improving the conveying stability. Upper rotating baffles and lower rotating baffles are respectively set on the left and right sides of the conveying trough. They are linked with the stepper motor through connecting rods, gears, and stepper motors. When the conveying plate moves, the stepper motor drives the gear to rotate, causing the baffles to open and close. When the workpiece enters the cooling chamber from the carburizing furnace, the left baffle opens and the right baffle closes to ensure the sealing of the cooling chamber. When the workpiece enters the cooling furnace, the right baffle opens. The sealing and conveying connection of each area can be completed without manual intervention. The servo motor and stepper motor are electrically connected to the PLC controller. The conveying speed, baffle opening and closing timing and other parameters can be preset through the PLC controller to realize the automated control of the conveying process. At the same time, combined with the temperature sensor data of the cooling furnace, the conveying speed can be adjusted in linkage, reducing the reliance on manual operation and reducing labor costs.

[0027] 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.

[0028] Please see Figure 1-7 The present invention provides the following technical solution:

[0029] A carburizing furnace cooling treatment integrated structure includes a carburizing furnace body 1, a cooling mechanism 2 welded to the right side of the carburizing furnace body 1, and a conveying mechanism 3 rotatably connected to the rear side of the inner side of the cooling mechanism 2. The cooling mechanism 2 includes a cooling chamber 201, a cooling furnace 202, a high-temperature fan 203, a discharge port 204, a sealing block 205, and a conveying trough 206. The cooling chamber 201 is welded to the right side of the carburizing furnace body 1, the cooling furnace 202 is welded to the right side of the cooling chamber 201, the high-temperature fan 203 is installed on the top of the cooling furnace 202, the discharge port 204 is opened on the right side of the cooling furnace 202, the sealing block 205 is snapped into the inner side of the discharge port 204, and the conveying trough 206 is opened in the inner side of the cooling chamber 201.

[0030] In this embodiment: the carburizing furnace body 1 is set to undertake the function of high-temperature carburizing of the workpiece, and at the same time, it can support and limit the cooling mechanism 2. The cooling chamber 201 forms a transition buffer area to avoid the temperature difference impact caused by the high-temperature workpiece directly entering the cooling furnace 202, thereby reducing the risk of workpiece deformation. The cooling furnace 202, together with the high-temperature fan 203, can quickly form a uniform airflow field, stabilize and control the cooling rate of the workpiece within a reasonable range, and improve the cooling efficiency. The high-temperature fan 203 can accelerate the air circulation in the furnace. The discharge port 204 provides a dedicated discharge channel for the workpiece after cooling. The sealing block 205 can close the discharge port 204 during the cooling process to prevent external air from entering and disrupting the cooling environment in the furnace. The conveying trough 206 provides a dedicated moving track for the conveying plate 304 to ensure that the conveying plate 304 moves smoothly along a fixed path.

[0031] Specifically, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the conveying mechanism 3 includes a lead screw 301, a limit rod 302, a servo motor 303, a conveying plate 304, an upper rotating baffle 305, a lower rotating baffle 306, a locking half hole 307, a connecting rod 308, four gears 309, a mounting plate 310, two stepper motors 311, and a PLC controller 312. The lead screw 301 is rotatably connected to the rear side of the inner side of the cooling furnace 202.

[0032] Specifically, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a connecting shaft is connected to the right side of the lead screw 301 via a flat key. A servo motor 303 is mounted on the right side of the cooling furnace 202. The output end of the servo motor 303 on the left side passes through the cooling furnace 202 and is fixedly connected to the right side of the connecting shaft. A limit rod 302 is welded to the front side of the inner side of the cooling furnace 202. A threaded sleeve is welded to the rear side of the conveyor plate 304, and the threaded sleeve is threadedly connected to the surface of the lead screw 301. A sliding sleeve is welded to the front side of the conveyor plate 304, and the sliding sleeve is slidably connected to the limit rod 301. On the surface of 2, the conveying plate 304 is slidably connected to the inner side of the carburizing furnace body 1, the conveying trough 206 and the cooling furnace 202 respectively. The upper rotating baffle 305 is rotatably connected to the top of the left side of the conveying trough 206 and the top of the right side of the conveying trough 206 respectively. The lower rotating baffle 306 is rotatably connected to the bottom of the left side of the conveying trough 206 and the bottom of the right side of the conveying trough 206 respectively. The snap-fit ​​half hole 307 is opened on both sides of the bottom of the upper rotating baffle 305 and both sides of the top of the lower rotating baffle 306 respectively.

[0033] Specifically, such as Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the snap-fit ​​half-hole 307 contacts the surfaces of the lead screw 301 and the limiting rod 302 respectively. The connecting rod 308 is welded to the rear side of the upper rotating baffle 305 and the rear side of the lower rotating baffle 306 respectively. The rear side of the connecting rod 308 penetrates the carburizing furnace body 1 and the cooling furnace 202 respectively and extends to the outer side of the carburizing furnace body 1 and the cooling furnace 202. The gear 309 is welded to the surface of the rear side of the connecting rod 308. The mounting plate 310 is welded to the carburizing furnace body 1 and the cooling furnace 202. At the rear of furnace 202, stepper motors 311 are mounted on both sides of the top of mounting plate 310. The rear sides of the left rear gear 309 and the right rear gear 309 are connected to connecting shafts via flat keys. The output end of the front side of the left rear stepper motor 311 is fixedly connected to the rear side of the left rear gear 309, and the output end of the front side of the right rear stepper motor 311 is fixedly connected to the rear side of the right rear gear 309. PLC controller 312 is mounted at the front of cooling furnace 202.

[0034] In this embodiment: the lead screw 301 drives the conveyor plate 304 to move via threaded transmission. The limiting rod 302 provides sliding guidance for the conveyor plate 304 to prevent rotational deviation during movement. The servo motor 303 can adjust its speed through the PLC controller 312 to control the moving speed of the conveyor plate 304. The conveyor plate 304 directly carries the workpiece, allowing the workpiece to complete the carburizing to cooling process without transfer. The upper rotating baffle 305 and the lower rotating baffle 306 are rotatably connected to the top and bottom of the two sides of the conveying trough 206, respectively. They can be opened and closed to isolate the cooling chamber 201 from the carburizing furnace and the cooling furnace 202, avoiding temperature interference between different areas. The snap-fit ​​half-hole 307 contacts the surfaces of the lead screw 301 and the limiting rod 302 without affecting the rotation of the rod. It can also fill the gap between the baffle and the rod, reducing the loss of heat in the furnace through the gap. The connecting rod 308 connects the baffle to the external gear 309, realizing the external drive of the baffle and avoiding damage caused by setting the drive component in the high temperature environment inside the furnace. The gear 309 transmits the power of the stepper motor 311 to the baffle through meshing transmission, realizing the synchronous opening and closing of the baffle and ensuring that the actions of the baffles on both sides are consistent. The mounting plate 310 provides a stable mounting base for the stepper motor 311. The stepper motor 311 can control the rotation angle through the PLC controller 312 to realize the flexible adjustment of the opening and closing degree of the baffle. The PLC controller 312 integrates the data of the servo motor 303, the stepper motor 311 and the temperature sensor 10 to realize the linkage control of conveying, cooling and temperature monitoring, reducing manual intervention and reducing the difficulty of operation.

[0035] Specifically, such as Figure 5 As shown, a feed inlet 4 is provided on the left side of the carburizing furnace body 1, and a sealing cover 5 is snapped into the inside of the feed inlet 4.

[0036] Specifically, such as Figure 6As shown, handles 6 are welded to both the left side of the sealing cover 5 and the right side of the sealing block 205, and the surface of the handles 6 is engraved with anti-slip texture.

[0037] In this embodiment: by setting the feed port 4, a dedicated entry channel is provided for the workpiece; by setting the sealing cover 5, the high temperature and atmosphere inside the carburizing furnace are kept stable through physical sealing, preventing leakage of carburizing medium or air entry; by setting the handle 6, the operator can easily open the sealing cover 5 or the sealing block 205; by setting the anti-slip texture, the friction between the hand and the handle 6 is increased, preventing slippage caused by sweat or oil on the hands.

[0038] Specifically, such as Figure 7 As shown, a filter ring 7 is movably connected to the top of the inner side of the high-temperature fan 203, and the surface of the filter ring 7 is coated with an anti-corrosion coating.

[0039] Specifically, such as Figure 6 As shown, anti-detachment rings 8 are welded to the rear side of both the left and right top connecting rods 308, and the surface of the anti-detachment rings 8 is coated with anti-corrosion paint.

[0040] In this embodiment: By setting a filter ring 7, dust and impurities in the air entering the cooling furnace 202 are filtered to prevent them from adhering to the surface of the workpiece and affecting accuracy, or from clogging the blades of the high-temperature fan 203 and causing malfunctions. By setting an anti-corrosion coating, the filter ring 7 can resist the erosion of residual carburizing media in the high-temperature environment and extend its service life. By setting an anti-detachment ring 8, the connecting rod 308 is prevented from axial displacement or falling off due to vibration and wear during long-term rotation, avoiding the baffle from losing its drive and failing, ensuring the continuous operation of the conveying process. By setting an anti-corrosion coating, the filter ring 8 can resist the erosion of the external environment of the furnace body, prevent it from rusting and being damaged, and extend the service life of the components.

[0041] Specifically, such as Figure 5 As shown, a protective pad 9 is fitted on the bottom of the inner side of the conveyor plate 304, and the surface of the protective pad 9 is engraved with anti-slip texture.

[0042] Specifically, such as Figure 7 As shown, a temperature sensor 10 is installed on the left side of the top of the cooling furnace 202, and the detection end of the temperature sensor 10 extends through and into the inside of the cooling furnace 202.

[0043] In this embodiment: by setting a protective pad 9, the impact of the workpiece is buffered by the flexible material, avoiding surface scratches and deformation caused by rigid contact between the workpiece and the conveyor plate 304, thus protecting the workpiece's precision. By setting anti-slip texture, the friction between the workpiece and the conveyor plate 304 is increased, preventing the workpiece from sliding off due to inertia during the conveying process. By setting a temperature sensor 10, the temperature data inside the cooling furnace 202 can be collected in real time.

[0044] Working principle: First, the operator opens the sealing cover 5 by holding the handle 6 of the sealing cover 5, which is snapped onto the inside of the feed inlet 4. The workpiece to be carburized is placed at the bottom inside the conveyor plate 304. Then, the operator closes the sealing cover 5, ensuring the stability of the high temperature and carburizing atmosphere inside the carburizing furnace through physical sealing, preventing leakage of carburizing medium or entry of external air. At this time, the carburizing furnace body 1 starts the high-temperature carburizing program and begins surface carburizing treatment of the workpiece. Next, after the workpiece has completed carburizing inside the carburizing furnace body 1, the operator issues a command through the PLC controller 312 to start the servo motor 303 and the left stepper motor 311 of the conveyor mechanism 3. The output end of the left side of the servo motor 303 drives the lead screw 301 to rotate through the connecting shaft. The lead screw 301 rotates through the screw... The threaded drive causes the conveyor plate 304, with its welded threaded sleeve, to move along the lead screw 301. Simultaneously, the sliding sleeve on the front side of the conveyor plate 304 slides along the limit rod 302, achieving smooth movement of the conveyor plate 304. At the same time, the left stepper motor 311 drives the left rear gear 309 to rotate through its output end. The gear 309, through meshing transmission, causes the connecting rod 308 to drive the upper rotating baffle 305 and the lower rotating baffle 306 on the left side of the conveyor trough 206 to open and close synchronously. The conveyor plate 304, carrying the high-temperature workpiece, passes through the opened baffle and enters the conveyor trough 206 of the cooling chamber 201 from the carburizing furnace body 1. Then, after the workpiece is buffered in the cooling chamber 201, it enters the cooling furnace 202. After the conveyor plate 304 has completely driven the workpiece into the cooling chamber 201, the PLC controller 312 controls the movement. The left stepper motor 311 reverses, closing the baffle on the left side of the conveyor trough 206 to prevent temperature interference between the cooling chamber 201 and the carburizing furnace body 1. Then, the PLC controller 312 starts the right stepper motor 311, driving the right rear gear 309 and connecting rod 308 to rotate, opening the baffle on the right side of the conveyor trough 206. The conveyor plate 304 continues to move, feeding the workpiece into the cooling furnace 202. Next, the right baffle closes, ensuring the cooling furnace 202 is sealed. At this time, the high-temperature fan 203 at the top of the cooling furnace 202 starts, accelerating air circulation inside the furnace and quickly forming a uniform airflow field to cool the workpiece. Simultaneously, the temperature sensor 10 on the top left side of the cooling furnace 202 collects the furnace temperature data in real time and feeds the data back to the PLC controller. The PLC controller 312 facilitates operator monitoring of the cooling progress. Based on the temperature monitoring data, the cooling status is adjusted to ensure the workpiece reaches the target cooling temperature. During the cooling process, the PLC controller 312 dynamically adjusts the speed of the high-temperature fan 203 based on real-time data from the temperature sensor 10, stabilizing the workpiece cooling rate within a reasonable range. This prevents workpiece deformation due to excessively rapid cooling or efficiency issues due to excessively slow cooling. Simultaneously, the sealing block 205 is engaged inside the discharge port 204 on the right side of the cooling furnace 202, keeping the furnace sealed and preventing external air from entering and disrupting the cooling environment, thus avoiding workpiece oxidation and reducing heat loss and energy consumption. Finally, when the temperature sensor 10 detects that the temperature inside the cooling furnace 202 has reached the preset target value and the workpiece has completed cooling, the process is complete.The PLC controller 312 issues a command to stop the high-temperature fan 203. The operator holds the handle 6 on the right side of the sealing block 205 to open the sealing block 205, which is locked inside the discharge port 204. After the workpiece is removed, the PLC controller 312 controls the servo motor 303 to reverse, causing the conveyor plate 304 to return to the vicinity of the carburizing furnace body 1 for reset, preparing for the feeding and processing of the next batch of workpieces to be carburized, and entering the next round of carburizing and cooling cycle.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
