Description

Technical Field

[0001] The invention relates to the technical field of heat treatment, and in particular to an intelligent quenching device suitable for heat treatment. Background Art

[0002] In the prior art, aluminum alloy castings are usually quenched by heating them to a specific temperature and then rapidly cooling them by spraying or immersing them; a heat treatment furnace (electric heating furnace) is generally used to heat the aluminum alloy castings, a quenching pool with a built-in water circulation system is used to rapidly cool the aluminum alloy castings, and a steel conveyor belt is used to transfer the aluminum alloy castings between the heat treatment furnace and the quenching pool.

[0003] Although the above scheme can relatively automatically complete the quenching step of aluminum alloy castings, the aluminum alloy castings are always attached to the conveyor belt during the heating and cooling process, which may easily lead to different cooling times at different positions of the castings, and then lead to different quenching completion degrees and poor quenching quality of various parts of the castings, and even prone to quenching distortion, cracking, scrapping, etc. caused by uneven cooling, which is not conducive to the actual processing and production of aluminum alloy castings; and when the conveyor belt in the above scheme transfers the castings, if the shape and structure of the castings are easy to roll, it is necessary to add a clamp or a base on the conveyor belt; but the applicability of the clamp and the base is poor.

[0004] In response to the above problems, the Chinese invention patent with patent number CN117265230B discloses an intelligent quenching production line suitable for aluminum alloy melting furnaces, which includes a heat treatment furnace, a quenching pool, a casting conveying assembly, and a pump air assembly; the casting conveying assembly includes a conveyor belt body with positioning holes arranged at equal intervals, a rotating driving wheel, a reversing shaping wheel for guiding the movement of the conveyor belt body, and a carrier frame, and the conveyor belt body is supported into an oblong shape by two sub-bell-shaped rotating driving wheels positioned on the carrier frame; a bearing soft bag is fixed on each positioning hole; the heat treatment furnace includes a furnace body and a support body which are rotatably connected to a casting lifting wheel inside the furnace; a wheel body protrusion is provided on the side wall of the casting lifting wheel; by arranging a soft metal net bag on the conveyor belt body, and adding a lifting wheel for lifting the net bag in the heat treatment furnace, and arranging a lifting assembly for lifting the net bag in the quenching pool, the contact position of the casting and the casting conveying assembly can be changed multiple times without affecting the movement of the casting.

[0005] Although the solution disclosed in the above patent effectively solves the technical problems in the prior art that the quenching production line is prone to uneven cooling of castings during the quenching process due to the limitation of the structure of the conveying equipment, and the poor applicability of the conveying equipment; however, due to the limitation of its own structure, the use of the soft carrying bag will cause the position of the placed castings to be uncertain due to rolling, and the positions of different placed castings vary greatly, which makes it difficult to use mechanical arms and other equipment to clamp out castings of various structures and arrange them in order after the heat treatment of the castings, which is not conducive to the implementation of automatic material feeding; if the castings are directly taken out manually, the labor intensity is high, which has a greater impact on production efficiency; at the same time, the different shapes and positions of the castings in the soft carrying bag may lead to relatively poor consistency of the castings after heat treatment, which will affect the quality of the finished product to a certain extent.

[0006] Therefore, there is a need for an intelligent quenching equipment suitable for heat treatment that is not only suitable for castings of various structures and can ensure that the castings are heated and cooled more evenly and quickly during quenching, but can also impose certain restrictions on the posture of the castings during the heat treatment process, facilitate the removal and placement of the castings, and effectively ensure the consistency of the finished products.

[0069] Embodiment 1:

[0073] The quenching pool 200 is used to quickly cool the casting, and includes a pool body, a support frame, a lifting component 230 in the pool and a water circulation system; the pool body is a container with an open top and a built-in quenching liquid; the support frame is a frame structure, fixed to the bottom of the pool body, and plays a bearing and supporting role, propping up the pool body so that it is suspended in the air; the lifting component 230 in the pool is fixed to the inner bottom of the pool body, arranged longitudinally, and the main body is cylindrical and has a telescopic rod structure. Under the control of the control unit, it can be extended and retracted to timely lift the casting being quenched; the water circulation system is a combination of a water pump and a pipe, which is used to promote the flow of liquid in the pool body 210 and thus ensure the cooling effect.

[0074] The main body of the casting conveying assembly is a conveyor belt structure, including a conveyor belt body 310, a rotating driving wheel 330, a reversing shaping wheel 340 and a carrier frame 350; the conveyor belt body 310 is a steel belt body (woven from steel wires), which is supported into an oblong shape by two rotating driving wheels 330; the conveyor belt body 310 passes through the inside and bottom of the heat treatment furnace 100 and the top and bottom of the quenching pool 200; the rotating driving wheel 330 is dumbbell-shaped as a whole, and has at least one built-in motor, which drives the conveyor belt body 310 to rotate under the drive of the motor; the carrier frame 350 is a plate or frame The frame structure is fixed on the ground and plays the role of bearing and positioning the rotating driving wheel 330 and the reversing shaping wheel 340; the rotating driving wheel 330 is positioned on the bearing frame 350; the reversing shaping wheel 340 is also a dumbbell-shaped wheel, and there are multiple of them, which are rotatably connected to the bearing frame 350 and are used to guide the movement of the conveyor belt body 310; some of the reversing shaping wheels 340 are positioned in the quenching pool 200, and these reversing shaping wheels 340 immerse the conveyor belt body 310 and the casting thereon into the quenching liquid by extrusion, and ensure that the casting can be completely immersed in the quenching liquid;

[0075] The conveyor belt body 310 is provided with positioning holes 311 at equal intervals, and the positioning holes 311 are through holes; each positioning hole 311 is fixed with a carrier 320 for carrying the casting;

[0076] like Figures 2 to 5 As shown, the carrier 320 is in the shape of a bag as a whole, made of metal, and includes a conical net bag 322 and a bottom carrier plate 326; the conical net bag 322 is in the shape of a trumpet-shaped tube as a whole, with a larger opening at one end and a smaller opening at the other end, and is formed by a plurality of metal rings nested and woven together, and the larger opening end is fixed on the edge of the positioning hole 311; the bottom carrier plate 326 is a hard metal plate, and the edge of the bottom carrier plate 326 is positioned (fixed) on the smaller opening end of the conical net bag 322; the bottom carrier plate 326 is densely covered with liquid permeable holes 327, and is provided with a plurality of protrusions and pits for placing the casting and limiting the movement of the casting; the liquid permeable holes 327 are through holes; a plurality of bottom attraction blocks 325 made of ferromagnetic material are fixed to the bottom of the bottom carrier plate 326, and the bottom attraction blocks 325 can be attracted by magnets, and the bottom attraction blocks 325 at the bottom of the bottom carrier plate 326 are of the same size and have equal spacing between each other;

[0077] The bottom bearing plate 326 is densely covered with top support bodies 361. The existence of the top support bodies 361 is used to further reduce the contact area between the casting and the bottom bearing plate 326, thereby ensuring the uniformity of heating and cooling of the casting; the existence of the conical net bag 322 can effectively limit the movement of the casting during the heat treatment process, and prevent the casting from deviating and falling during movement and cooling, and from falling under the impact of water flow.

[0078] One or more casting lifting bodies 110 and sliding guide rails 120 are positioned in the heat treatment furnace 100; the casting lifting body 110 is located below the conveyor belt body 310 in the furnace body and is slidably positioned on the sliding guide rail 120, and moves along the sliding guide rail 120 under the control of the control unit; the main body of the casting lifting body 110 is a longitudinally arranged telescopic rod structure, which is telescoped under the control of the control unit to timely lift the casting being heated.

[0079] The adsorption and shaping component is fixed at the entrance of the furnace body and is located in the space surrounded by the conveyor belt body 310. It is used to adsorb the bottom attraction block 325 on the bottom supporting plate 326 by magnetic force, thereby ensuring the stretching of the supporting body 320 and avoiding the wrinkles of the supporting body 320 that affect the positioning of the casting; the adsorption and shaping component includes a supporting frame body 410 and an adsorption magnet 420; the supporting frame body 410 is fixed on the furnace body, and is a rod-shaped, plate-shaped or frame structure, which plays a role of bearing and fixing; the adsorption magnet 420 is a horizontally arranged plate-shaped magnet, which is a permanent magnet or an electromagnet, fixed on the top of the supporting frame body 410; the supporting body 320 does not directly contact the adsorption magnet 420 when it is in a stretched state.

[0080] The power assembly is used to provide power for the operation of various components of the intelligent quenching equipment suitable for heat treatment in this application, and the control unit plays a role in controlling the coordinated operation of various components of the intelligent quenching equipment suitable for heat treatment. Both are prior arts and will not be elaborated here.

[0081] Preferably, the control unit is a combination of a programmable logic controller and control buttons.

[0082] During the processing, the heating and cooling times and the running speed of the conveyor belt 310 are changed according to the size and shape of the casting.

[0083] The position of the furnace body close to the adsorption and shaping component is the placement area 003, which is used to place the castings on the conveyor belt body 310; the end of the casting conveying component away from the furnace body is the removal area 004, which is used to take out the processed castings.

[0084] This application is applicable to the use of intelligent quenching equipment for heat treatment:

[0085] 1. The suction and shaping component suction bottom attraction block 325 ensures that the carrier 320 moved to the top thereof is stretched out;

[0086] 2. In the placement area 003, use a clamping device such as a robot arm to place the trimmed casting in the stretched carrier 320; (pre-set the moving track in the clamping and moving device such as a robot arm according to the structure and size of the casting, and use the protrusions and pits on the bottom carrier plate to ensure that the casting placed in the carrier 320 can be stably placed and the position is determined);

[0087] 3. Control the operation of the casting conveying assembly to convey the casting to the heat treatment furnace 100 and the quenching pool 200 for quenching; when the casting moves to the top of the casting lifting body 110, control the casting lifting body 110 to extend to lift the bottom bearing plate 326 to ensure uniform heating of the casting; when the casting moves to the top of the lifting assembly 230 in the pool, control the lifting assembly 230 in the pool to extend and retract multiple times to make the casting cool more thoroughly;

[0088] 4. After the casting is moved to the retrieval area 004, use a clamping device such as a robotic arm to stably take out the heat-treated casting and place it in order on a carrier such as a pallet and a conveyor belt to enter the next process (a very small number of castings may be separated from their original position due to the impact of water flow, etc., making it difficult to clamp them correctly when taking them out, but even if there are castings that cannot be taken out of the carrier 320, they will fall to the ground as the casting conveying assembly runs, which will not affect the normal operation of the production line).

[0089] Furthermore, the casting lifting body 110 includes a lifting rod 111 and a top plate 112 . The lifting rod 111 is slidably positioned on the sliding guide rail 120 and is an electric telescopic rod structure. The top plate 112 is a hard plate body, horizontally arranged, and fixed on the top of the lifting rod 111 .

[0090] Preferably, Figure 6 As shown, a casting lifting body 110 includes a plurality of lifting rods 111, and a top plate 112 is positioned on each of the lifting rods 111; when the plurality of lifting rods 111 are extended, the extension amounts are different and continuously change, so that the inclination angle of the casting thereon continuously changes during the lifting process (during the change process, it is necessary to ensure that the casting does not slide or roll due to the inclination), which is conducive to uniform heating.

[0091] Preferably, Figure 8 As shown, in order to further ensure the uniformity of heating, the top of the top plate 112 is densely covered with insertion needles 113. When the top plate 112 moves upward, the insertion needles 113 are inserted into the liquid-permeable holes 327 of the bottom supporting plate 326 to lift the casting thereon to a certain height.

[0092] Preferably, the top of the lifting assembly 230 in the pool is also densely covered with insertion needles 113 to increase the contact surface between the casting and the quenching liquid during cooling, thereby increasing the cooling efficiency and ensuring cooling uniformity.

[0093] Preferably, the structure of the in-pool lifting assembly 230 is the same as that of the casting lifting body 110 .

[0094] Preferably, Figure 7 As shown, the top support body 361 is needle-shaped.

[0095] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0096] The invention solves the technical problems that the intelligent quenching production line suitable for aluminum alloy melting furnace in the prior art is limited by its own structure, which makes it difficult to clamp and orderly place the castings using various equipment such as mechanical arms after the heat treatment, which is not conducive to automatic material feeding and the consistency of the castings after heat treatment is relatively poor; the intelligent quenching equipment suitable for heat treatment is achieved. It can not only be suitable for castings of various structures, but also ensure that the castings are heated and cooled relatively evenly and quickly during quenching, and can also impose certain restrictions on the posture of the castings during the heat treatment process, facilitate the removal and placement of the castings, and effectively ensure the consistency of the finished product.
