Description

Technical Field

[0002] Traditional continuous quenching processes usually involve directly immersing heated metal workpieces in water or other cooling media for rapid cooling to achieve the required hardness and strength.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1 to 9 shown, the present invention provides an on-line quenching system, including a lifting mechanism 3 and a box body 1. A box cover 2 is covered on the top of the box body 1. The lifting mechanism 3 is used to lift the box body 1. The box body 1 is provided with a cooling mechanism 4, and the cooling mechanism 4 includes a water spraying mechanism 41 and an air jet mechanism 42;

[0035] The water spraying mechanism 41 includes a water pump 411. The water pump 411 is connected with a conveying pipe network for conveying water. The conveying pipe network is arranged in the box body 1 and in the box cover 2. The conveying pipe network is provided with at least one nozzle 415 for spraying water. The conveying pipe network includes a lower horizontal pipe 413 and an upper horizontal pipe 414. The lower horizontal pipe 413 is installed in the;

[0036] The jetting mechanism 42 includes a third blower 421 and a fourth blower 424. A lower air chamber 423 is installed in the box body 1, and an upper air chamber 425 is installed in the box cover 2. At least one air outlet head 426 for air outlet is installed in the lower air chamber 423 and the upper air chamber 425. The third blower 421 is connected to the lower air chamber 423, and the fourth blower 424 is connected to the upper air chamber 425.

[0037] During operation, the heated metal workpiece is placed in the box body 1, and then the cooling mechanism 4 is started. The cooling mechanism 4 includes a water spraying mechanism 41 and a jetting mechanism 42. The water spraying mechanism 41 is driven by a water pump 411, and water is transported through a pipe network to the delivery pipe networks arranged in the box body 1 and the box cover 2, and the workpiece is evenly sprayed and cooled through a plurality of nozzles 415. At the same time, the jetting mechanism 42 uses the third blower 421 and the fourth blower 424 to supply air to the lower air chamber 423 installed in the box body 1 and the upper air chamber 425 installed in the box cover 2 respectively, and the workpiece is jet-cooled through the air outlet heads 426. This combination method can flexibly adjust the proportion and rate of water spraying and jetting according to actual needs, so as to achieve precise control of the cooling speed, effectively reducing internal stress and deformation problems caused by uneven cooling. Since the local spraying method is adopted instead of the overall immersion method, the usage amount of the cooling medium is greatly reduced, the production cost is reduced, and the environmental protection pressure is alleviated.

[0038] Further, as a preferred implementation manner of the present invention rather than a limitation, the delivery pipe network includes a connecting pipe 412, the connecting pipe 412 has a telescopic function, the air outlets of the third blower 421 and the fourth blower 424 are fixedly connected with air ducts 422, the air ducts 422 have a telescopic function, one end of the air duct 422 connected to the third blower 421 is connected to the lower air chamber 423, and one end of the air duct 422 connected to the fourth blower 424 is connected to the upper air chamber 425. The telescopic functions of the connecting pipe 412 and the air ducts 422 enable the system to adapt to different positions of the box cover 2, ensuring a stable supply of the cooling medium in any operating state, and improving the flexibility and reliability of the equipment.

[0039] Further, as a preferred embodiment of the present invention rather than a limitation, at least one air-permeable mechanism 15 is installed on the side wall of the box body 1. The air-permeable mechanism 15 is composed of a number of corrugated plates 151. The corrugated plates 151 are plates with continuous concave and convex shapes on the surface. A gap for air permeability is provided between two adjacent corrugated plates 151. During the quenching process, the jetting mechanism 42 supplies gas to the lower air chamber 423 in the box body 1 and the upper air chamber 425 in the box cover 2 through the third blower 421 and the fourth blower 424, generating a large amount of gas. These gases are discharged outside the box body through the gaps between the corrugated plates 151, ensuring that the pressure in the box body will not increase due to gas accumulation. At the same time, the design of the air-permeable mechanism 15 enables it to effectively discharge the wind generated by the jetting mechanism without allowing the water of the water spraying mechanism 41 to leak through these gaps. Specifically, the corrugated plates 151 have continuous concave and convex shapes. This design not only provides sufficient air-permeable channels but also can block the passage of liquid. The concave and convex shapes enable the gas to flow smoothly through the gaps, while the liquid is difficult to pass through these small holes due to the surface tension and gravity.

[0040] Further, as a preferred embodiment of the present invention rather than a limitation, the box body 1 is equipped with a feeding mechanism 11 for conveying materials. The feeding mechanism 11 includes a frame body 111. The frame body 111 is fixedly connected to the inner cavity of the box body 1. A number of rollers 112 are installed on the frame body 111. The rollers 112 are rotatably connected to the frame body 111. During the operation, the heated metal workpiece enters the box body 1 through the feeding mechanism 11 for quenching treatment. Specifically, the workpiece is placed on the rollers 112, and the rollers 112 are rotated by an external driving device, thereby driving the workpiece to move smoothly to the designated position.

[0041] Optionally, in some embodiments, the feeding mechanism 11 includes a motor, and the motor is rotatably connected to the rollers 112.

[0042] Further, as a preferred embodiment of the present invention rather than a limitation, air curtain mechanisms 12 are installed at both ends of the box cover 2. The air curtain mechanism 12 includes a first blower 121. The air outlet of the first blower 121 is equipped with a first air outlet nozzle 122, and the air outlet of the first air outlet nozzle 122 faces downward. When the heated metal workpiece enters the box body 1 through the feeding mechanism 11, the first blower 121 is started, and an air flow is blown downward through the first air outlet nozzle 122 to form an air barrier. This air curtain can effectively prevent external air and impurities from entering the box body and ensure that the cooling medium (such as water vapor and cold air) in the box body will not escape to the external environment.

[0043] Further, as a preferred embodiment of the present invention but not a limitation, a drying mechanism 14 is installed at one end of the box body 1, and the drying mechanism 14 includes a second fan 141, and the air outlet of the second fan 141 is installed with a second air outlet nozzle 142, and the second air outlet nozzle 142 is installed at one end of the box body 1, and the air outlet of the second air outlet nozzle 142 is upward. When the workpiece after water spraying and air jet cooling is removed from the box body 1 through the feeding mechanism 11, the second fan 141 is started, and a strong airflow is blown upward through the second air outlet nozzle 142 to quickly dry the moisture attached to the surface of the workpiece. At the same time, the first fan 121 of the air curtain mechanism 12 continues to blow air downward, and is used in conjunction with the drying mechanism 14 to improve the drying efficiency.

[0044] Further, as a preferred embodiment of the present invention but not limiting, a pumping unit 13 is installed on one side of the box body 1, and the pumping unit 13 is a water pump, and the pumping unit 13 is used to pump out the accumulated water inside the box body 1. When the heated metal workpiece enters the box body 1 through the feeding mechanism 11, the water spraying mechanism 41 and the air jet mechanism 42 are started to quickly cool the workpiece. A large amount of water generated during the cooling process will accumulate at the bottom of the box body 1. In order to ensure that the inside of the box body 1 is always dry and ready for the processing of the next workpiece, the pumping unit 13 (i.e., the water pump) is started to pump out the cooling water accumulated at the bottom of the box body 1.

[0045] Further, as a preferred embodiment of the present invention but not limited thereto, the lifting mechanism 3 includes a support frame 31, the motor 32 is installed, the motor 32 is connected to a connecting shaft 36 in a transmission manner, the first gear 33 is installed at both ends of the connecting shaft 36, the first gear 33 is installed with a chain 35, the chain 35 is meshed with a second gear 34, the first gear 33 is connected to the second gear 34 in a transmission manner through the chain 35, and one end of the chain 35 is fixedly connected to the box body 1. When the motor 32 is started, the connecting shaft 36 drives the first gear 33 to rotate, and the first gear 33 drives the second gear 34 to rotate through the chain 35. Since the chain 35 is fixedly connected to the box cover 2, the movement of the chain directly drives the box cover 2 to move up and down. The box cover 2 can be easily lifted by the lifting mechanism 3, which is convenient for the staff to inspect the interior of the box body 1 and the box cover 2, which greatly simplifies the workflow of daily maintenance and troubleshooting.

[0046] Further, as a preferred embodiment of the present invention but not a limitation, sliders 37 are provided on both sides of the support frame 31, and the sliders 37 are slidably connected to the support frame 31. At least one limiting wheel 38 is provided on both sides of the slider 37, and the limiting wheel 38 is slidably connected to the slider 37. The limiting wheel 38 is installed on the support frame 31, and one end of the slider 37 is fixedly connected to the box cover 2. Through the design of the slider 37 and the limiting wheel 38, the lifting mechanism can provide a smoother operating experience during the lifting and lowering of the box cover 2. The limiting wheel 38 reduces the friction of the slider 37 during movement, avoiding shaking and deviation. The limiting wheel 38 not only plays a guiding role, but also effectively prevents the slider 37 from deviating from the track, thereby improving the safety of the equipment.

[0047] Further, as a preferred embodiment of the present invention but not limited thereto, both sides of the slider 37 are provided with connecting parts, and the wheel wall of the limiting wheel 38 is provided with a matching part, and the matching part is engaged with the connecting part. The connecting part is a clamping strip, and the matching part is a clamping groove engaged with the clamping strip. By inserting the clamping strip into the clamping groove, a stable connection between the slider 37 and the limiting wheel 38 is achieved. This clamping design not only simplifies the installation process, but also ensures that the slider 37 will not fall off the track during movement, thereby enhancing stability and reliability.

[0048] Optionally, in some embodiments, the connecting portion is a card slot, and the matching portion is a card strip that is card-connected with the card strip.

At the same time, the air jetting mechanism 42 uses a third fan 421 and a fourth fan 424 to supply air to the lower air chamber 423 installed inside the box body 1 and the upper air chamber 425 inside the box cover 2 respectively, and the workpiece is cooled by jetting air through the air outlet head 426. This combined method can flexibly adjust the proportion and rate of water spraying and air jetting according to actual needs, so as to achieve precise control of the cooling speed, effectively reducing the internal stress and deformation problems caused by uneven cooling. Since the local spraying method is adopted instead of the overall immersion method, the usage amount of the cooling medium is greatly reduced, the production cost is reduced, and the environmental protection pressure is relieved.

[0054] A water pumping part 13 is installed on one side of the box body 1. The water pumping part 13 is a water pump, and the water pumping part 13 is used to pump out the accumulated water inside the box body 1. After the heated metal workpiece enters the box body 1 through the feeding mechanism 11, the water spraying mechanism 41 and the air jetting mechanism 42 are started to quickly cool the workpiece. A large amount of water generated during the cooling process will accumulate at the bottom of the box body 1. To ensure that the inside of the box body 1 always remains dry and is ready for the processing of the next workpiece, the water pumping part 13 (i.e., the water pump) is started to pump out the cooling water accumulated at the bottom of the box body 1.

[0055] The conveying pipe network includes a connecting pipe 412. The connecting pipe 412 has a telescopic function. The air outlet of the third fan 421 and the air outlet of the fourth fan 424 are both fixedly connected with an air duct 422. The air duct 422 has a telescopic function. One end of the air duct 422 connected to the third fan 421 is connected to the lower air chamber 423, and one end of the air duct 422 connected to the fourth fan 424 is connected to the upper air chamber 425.

[0056] At least one ventilation mechanism 15 is installed on the side wall of the box body 1. The ventilation mechanism 15 is composed of a number of corrugated plates 151. The corrugated plates 151 are plates with continuous concave and convex shapes on the surface. A gap for ventilation is provided between two adjacent corrugated plates 151. During the quenching process, the air jet mechanism 42 supplies air to the lower air chamber 423 in the box body 1 and the upper air chamber 425 in the box cover 2 through the third fan 421 and the fourth fan 424, generating a large amount of gas. These gases are discharged outside the box body through the gaps between the corrugated plates 151, ensuring that the pressure in the box body will not increase due to gas accumulation. At the same time, the design of the ventilation mechanism 15 enables it to effectively discharge the wind generated by the air jet mechanism without allowing the water of the water spraying mechanism 41 to leak through these gaps. Specifically, the corrugated plates 151 have continuous concave and convex shapes. This design not only provides sufficient ventilation channels but also can block the passage of liquid. The concave and convex shapes enable the gas to flow smoothly through the gaps, while the liquid is difficult to pass through these small holes due to the action of surface tension and gravity.

[0057] The box body 1 is equipped with a feeding mechanism 11 for conveying materials. The feeding mechanism 11 includes a frame body 111. The frame body 111 is fixedly connected to the inner cavity of the box body 1. A number of rollers 112 are installed on the frame body 111. The rollers 112 are rotatably connected to the frame body 111. During the operation, the heated metal workpiece enters the box body 1 through the feeding mechanism 11 for quenching treatment.

A first air outlet nozzle 122 is installed at the air outlet of the first fan 121. The air outlet of the first air outlet nozzle 122 faces downward. When the heated metal workpiece enters the box body 1 through the feeding mechanism 11, the first fan 121 starts and blows out an air current downward through the first air outlet nozzle 122, forming an air barrier. This air curtain can effectively prevent external air and impurities from entering the box body and ensure that the cooling medium (such as water vapor and cold air) in the box body will not escape to the external environment.

The first gear 33 is connected to the second gear 34 in a transmission manner through the chain 35, and one end of the chain 35 is fixedly connected to the box body 1. When the motor 32 is started, the connecting shaft 36 drives the first gear 33 to rotate, and the first gear 33 drives the second gear 34 to rotate through the chain 35. Since the chain 35 is fixedly connected to the box cover 2, the movement of the chain directly drives the box cover 2 to move up and down.

The limiting wheel 38 is installed on the support frame 31, and one end of the slide block 37 is fixedly connected to the box cover 2. Through the design of the slide block 37 and the limiting wheel 38, the lifting mechanism can provide a smoother operating experience during the lifting and lowering of the box cover 2. The limiting wheel 38 reduces the friction of the slide block 37 during the movement, avoiding shaking and offset phenomena.

[0062] The water pump 411 and the fans (the third fan 421 and the fourth fan 424) all use variable frequency technology, which can dynamically adjust the speed and pressure of water supply and air supply according to the specific needs of the workpiece. The nozzle 415 and the air outlet 426 are also equipped with temperature sensors to monitor the temperature changes in the cooling area in real time and automatically adjust the cooling parameters as needed.

[0063] The roller 112 is not only rotatably connected to the frame 111, but is also equipped with a servo motor and an encoder to accurately control the speed and position of the roller. Through an external controller or an automated production line system, the staff can remotely monitor and adjust the feeding speed to ensure that the workpiece can enter and leave the box 1 smoothly and accurately.

[0064] Specifically, the working principle of the present invention is as follows:

[0065] The on-line quenching system realizes efficient and precise quenching treatment through the lifting mechanism 3, the box body 1 and various cooling and auxiliary mechanisms inside it. First, the heated metal workpiece enters the box body 1 through the feeding mechanism 11. The feeding mechanism 11 includes a frame body 111 and a number of rotatably connected rollers 112 to ensure that the workpiece can be smoothly moved to the designated position. Subsequently, the cooling mechanism 4 is started. This mechanism includes a water spraying mechanism 41 and an air jetting mechanism 42. The water spraying mechanism 41 is driven by a water pump 411, and water is transported through a pipe network to the conveying pipe networks arranged inside the box body 1 and inside the box cover 2, and the workpiece is evenly sprayed and cooled through a number of nozzles 415; the air jetting mechanism 42 uses a third fan 421 and a fourth fan 424 to supply air to the lower air chamber 423 arranged inside the box body 1 and the upper air chamber 425 inside the box cover 2, and the workpiece is jet-cooled through the air outlet head 426. This combination method can flexibly adjust the proportion and rate of water spraying and air jetting according to actual needs, so as to achieve precise control of the cooling rate.

[0066] At the same time, in order to maintain the purity and stability of the internal environment of the box body 1, a ventilation mechanism 15 is installed on the side wall of the box body 1. This mechanism consists of a number of corrugated plates 151 with continuous concave and convex shapes on the surface. A gap for ventilation is provided between two adjacent corrugated plates 151. These gaps allow gas to be discharged smoothly but block the passage of liquid, ensuring that no leakage occurs. In addition, air curtain mechanisms 12 are installed at both ends of the box cover 2. The first fan 121 blows out an air flow downward through the first air outlet nozzle 122 to form an air barrier to prevent external air and impurities from entering the inside of the box body. When the workpiece is cooled and removed from the box body 1 through the feeding mechanism 11, the second fan 141 blows out a strong air flow upward through the second air outlet nozzle 142 to quickly dry the moisture on the surface of the workpiece and improve the drying efficiency.

[0067] The lifting mechanism 3 is responsible for lifting the box cover 2 to facilitate the maintenance of the inside of the box body 1 and the box cover 2 by the staff. The lifting mechanism 3 includes a support frame 31, a motor 32, a connecting shaft 36, a first gear 33, a chain 35 and a second gear 34. After the motor 32 is started, the connecting shaft 36 drives the first gear 33 to rotate. The first gear 33 drives the second gear 34 to rotate through the chain 35. One end of the chain 35 is fixedly connected to the box cover 2, so as to realize the lifting of the box cover 2. Sliders 37 are arranged on both sides of the support frame 31. The sliders 37 are slidably connected to the support frame 31 and are equipped with limit wheels 38. The limit wheels 38 are slidably connected to the sliders 37 and are installed on the support frame 31. One end of the slider 37 is fixedly connected to the box cover 2. Card strips are arranged on both sides of the slider 37, and card slots for clamping with the card strips are arranged on the wheel wall of the limit wheel 38 to ensure that the slider 37 will not deviate from the track during the movement process, improving the stability and safety of the system.

[0068] In summary, the present invention solves the problems of inaccurate control of the cooling rate and uneven cooling of workpieces in traditional quenching methods, resulting in internal stress and deformation.

[0069] It should be understood that in the present invention, terms such as "first" and "second" are used to describe various information, but such information should not be limited to these terms, and these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information. In addition, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0070] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and deformations can be made, and these improvements and deformations are also regarded as the protection scope of the present invention.
