Description

Technical Field

[0001] This utility model relates to the field of tempering furnace technology, specifically a forging tempering furnace with a tempering cold air device. Background Technology

[0002] In large-scale industrial production, a large number of metal workpieces need to be tempered. Traditional small tempering equipment cannot meet the requirements of production efficiency. The emergence of tempering furnaces allows multiple workpieces to be tempered simultaneously, greatly improving production efficiency. For example, in large machining enterprises or metal product factories, a large tempering furnace can process hundreds or thousands of small metal parts or dozens of large metal components at once, meeting the needs of batch production. Industrial production has high requirements for the stability of product quality. Through precise temperature control, uniform heating environment and standardized tempering process, tempering furnaces can ensure that each workpiece obtains a consistent tempering effect, thereby ensuring the stability of product quality. This is crucial for the production of high-precision, high-performance metal products, such as aerospace parts and precision mechanical components, which all require strict tempering treatment in tempering furnaces to meet their quality standards.

[0003] In the existing technology, in machining workshops, some metal blanks that require high-precision machining need to be tempered before processing. Forging tempering furnaces with tempering cold air devices can provide suitable pretreatment for these blanks. However, in use, the existing cold air devices are usually fixed and cannot flexibly change the blowing angle according to the shape and size of the workpiece, resulting in uneven cooling. Furthermore, during the blowing process, the cold air may blow up impurities on the surface of the workpiece, and the airflow may cause injury to the operator when it is discharged.

[0004] Therefore, a forging tempering furnace with a tempering cold air device was proposed. Utility Model Content

[0022] 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.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1:

[0025] A preferred embodiment of the forging tempering furnace with tempering cold air device provided by this utility model is, for example... Figure 1-4 As shown: A forging tempering furnace with a tempering cold air device includes a tempering furnace 1, with support legs 2 fixedly installed at equal intervals on both sides of the bottom of the tempering furnace 1, a cabinet door 3 movably installed on the front of the tempering furnace 1, an opening in the top of the tempering furnace 1, a cold air regulating component 4 installed on the top of the tempering furnace 1, and protective components 5 installed on both sides of the tempering furnace 1.

[0026] The cold air regulating component 4 specifically includes: a hollow concave plate 411, fixedly installed on the top of the tempering furnace 1; a rotating rod 412, located on both sides of the hollow concave plate 411; a semi-circular gear 413, fixedly installed on one end of the rotating rod 412; a compressed air chiller 415, fixedly installed on one side of the top of the tempering furnace 1; a side plate 417, fixedly installed on one side of the tempering furnace 1; a grooved plate 4114, equidistantly fixedly installed on the top of the tempering furnace 1; and an electric push rod 4117, fixedly installed on one side of the side plate 417.

[0027] The other end of the rotating rod 412 moves through one side of the hollowed-out concave plate 411 and extends into the interior of the hollowed-out concave plate 411. The outer wall of the rotating rod 412 is rotatably connected to the inner wall surface of the hollowed-out concave plate 411. A nozzle 414 is fixedly installed between the rotating rods 412.

[0028] A connecting pipe 416 is installed on the top of the compressed air refrigeration unit 415. The other end of the connecting pipe 416 is connected to the top of the nozzle 414. An electric actuator 418 is fixedly installed on one side of the side plate 417. A connecting plate 419 is fixedly installed on the telescopic end of the electric actuator 418.

[0029] A toothed plate 4111 is meshed with the surface of the semi-circular gear 413. Grooved rods 4112 are fixedly installed on both sides of the bottom of the toothed plate 4111. One side of the grooved rod 4112 is fixedly connected to the other side of the connecting plate 419. A roller 4113 is rotatably connected between the inner walls of the grooved rod 4112. The surface of the roller 4113 is in contact with the top of the tempering furnace 1. A slider 4115 is slidably connected to the inner wall of the grooved plate 4114. A sealing plate 4116 is fixedly installed between the inner sides of the slider 4115. One side of the sealing plate 4116 is fixedly installed at the telescopic end of the electric push rod 4117.

[0030] In this example, multi-angle air cooling can be achieved by setting up the cold air adjustment component 4. Activating the electric actuator 2 4117 drives the sealing plate 1 4116 to move, disengaging it from the hole. Activating the electric actuator 1 418 drives the connecting plate 419 to move, and through the grooved rod 4112, drives the toothed plate 4111 to move. The toothed plate 4111 drives the semi-circular gear 413, the rotating rod 412, and the nozzle 414 to rotate, thereby achieving the function of angle adjustment.

[0031] Example 2:

[0032] Based on Embodiment 1, a preferred embodiment of the forging tempering furnace with a tempering cold air device provided by this utility model is, for example... Figure 1-4 As shown: The protective component 5 specifically includes: an exhaust frame 511, which is connected and installed on both sides of the tempering furnace 1; a recess 512, which is fixedly installed on both sides of the exhaust frame 511; and a top plate 518, which is fixedly installed on both sides of the tempering furnace 1.

[0033] The outer wall of the exhaust frame 511 is movably fitted with a collar 513. A locking block 514 is fixedly installed on one side of the collar 513. The outer wall of the locking block 514 is engaged with the inner wall of the recess 512. A high-temperature resistant filter frame 515 is fixedly installed on the other side of the collar 513.

[0034] A pull rod 516 is provided on the top of the exhaust frame 511. Insert rods 517 are fixedly installed on both sides of the bottom of the pull rod 516. The bottom of the insert rods 517 respectively movably passes through the top of the recess 512 and the top of the locking block 514 and extends to the bottom of the recess 512. An electric push rod 519 is fixedly installed on the bottom of the top plate 518. A sealing plate 5111 is fixedly installed on the telescopic end of the electric push rod 519. The bottom of the sealing plate 5111 movably passes through the top of the exhaust frame 511 and extends to the inner wall of the exhaust frame 511 to engage with it.

[0035] In this example, the protective component 5 is used to isolate impurities. The electric actuator 3 519 is activated to drive the sealing plate 2 5111 to rise, breaking away from the isolation of the air intake frame 511. The high-temperature resistant filter frame 515 intercepts the impurities in the discharged gas, preventing them from affecting the surrounding environment, thereby achieving the protective effect.

[0036] Working principle: First, the operator activates electric actuator 2 4117 to move sealing plate 1 4116. Sealing plate 1 4116 slides stably within grooved plate 4114 via slider 4115, disengaging from the hole. Then, electric actuator 3 519 is activated to raise sealing plate 2 5111, disengaging from the air inlet frame 511. Next, compressed air compressor 415 is activated to generate cold air, which cools the workpieces inside tempering furnace 1 via connecting pipe 416 and nozzle 414. When the angle of nozzle 414 needs adjustment, electric actuator 1 418 is activated to move connecting plate 419, which in turn moves toothed plate 4111 via grooved rod 4112. Groove rod 4112 is connected to roller 411. 3. Sliding stably on the tempering furnace 1, the toothed plate 4111 drives the semi-circular gear 413, the rotating rod 412 and the nozzle 414 to rotate. The gas will be discharged through the exhaust pipe 511 and then the high-temperature resistant filter frame 515 will intercept the impurities in the discharged gas to prevent it from affecting the surrounding environment. When it is necessary to clean the high-temperature resistant filter frame 515, the operator pulls the pull rod 516 to drive the insert rod 517 upward and disengage it from the concave block 512 and the locking block 514. Then the high-temperature resistant filter frame 515 and the collar 513 are removed from the exhaust pipe 511, and the locking block 514 is separated from the concave block 512, which facilitates the cleaning of the high-temperature resistant filter frame 515 in the later stage, thereby achieving the function of cold air regulation and protection.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
