[0002] Annealing furnaces are a metal heat treatment process in which metal parts are slowly heated to a certain temperature in different annealing furnaces, held at that temperature for a period of time, and then cooled at a suitable rate. The purpose is to soften materials or workpieces that have been cast, forged, welded, or machined, reduce hardness, improve plasticity and toughness, homogenize chemical composition, remove residual stress, or obtain the desired physical properties.

[0003] For example, utility model patent CN213388805U discloses an annealing furnace for metal processing, including a housing. The bottom of the housing has a second device cavity, and the bottom of the second device cavity has a motor. The output shaft of the motor is fixedly connected to a first rotating shaft. The other end of the first rotating shaft passes through the top wall of the second device cavity and extends into the housing. The middle of the housing has two arc-shaped plates. The other end of the first rotating shaft is fixedly connected to the bottom end of one arc-shaped plate, and the bottom end of the other arc-shaped plate is fixedly connected to a second rotating shaft. The metal to be processed is located in the middle of the two arc-shaped plates. When the device is in use, the heating and cooling air ducts are respectively located on one side of the metal to be processed. During the production process, it is impossible to heat or cool the entire metal to be processed at the same time. One side of the metal to be processed is always in an unprocessed state, which reduces the production quality of the annealing furnace. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an annealing furnace for metal processing, which solves the problem that in existing annealing furnaces, the heating and cooling air ducts are located on one side of the metal to be processed, making it impossible to heat or cool the entire metal to be processed simultaneously during production. As a result, one side of the metal to be processed is always unprocessed, which reduces the production quality of the annealing furnace.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an annealing furnace for metal processing, comprising a base, a furnace body mounted on the base, a baffle mounted inside the furnace body, a first chamber above the baffle, a first hot air channel and a first cold air channel within the first chamber, a plurality of second hot air channels on the first hot air channel, a plurality of second cold air channels on the first cold air channel, a hot air blower and a cold air blower mounted on the furnace body, the first hot air channel and the first cold air channel being respectively connected to the hot air blower and the cold air blower, a plurality of first exhaust holes on the second hot air channel, a plurality of second exhaust holes on the second cold air channel, a second chamber below the baffle, a support plate movably mounted inside the second chamber, a multi-stage electric telescopic cylinder mounted on the upper wall of the support plate, a placement platform mounted on the telescopic end of the multi-stage electric telescopic cylinder, a groove on the baffle, and the placement platform movably mounted within the groove of the baffle.

[0006] Preferably, the furnace body is provided with a pair of sliding grooves, and the support plate is provided with a pair of sliders, and the support plate is slidably installed in the sliding grooves via the sliders.

[0007] Preferably, the furnace body is provided with an insert block, the furnace body is provided with a cavity, the insert block is provided with a stop block located in the cavity of the furnace body, the insert block is provided with a spring, the insert block is provided with a handle, one of the sliders is provided with a first limiting groove and a second limiting groove, and the insert block is movably disposed in the first limiting groove and the second limiting groove.

[0008] Preferably, the second hot air channel and the second cold air channel are annular pipes, and the second hot air channel and the second cold air channel are arranged alternately in the first chamber.

[0009] Preferably, the furnace body is hinged with a protective door.

[0010] Beneficial effects

[0011] The annealing furnace for metal processing provided by this utility model has the following beneficial effects:

[0012] The second hot air channel and the second cold air channel of this design are arranged alternately in the first chamber. The second hot air channel and the second cold air channel are located around the metal to be processed. During the production process, the entire metal to be processed can be heated or cooled at the same time, thereby improving the production quality of the annealing furnace.

[0013] This design uses a multi-stage electric telescopic cylinder to extend and retract, thereby raising and lowering the placement platform. The placement platform is movably positioned within the groove of the baffle. When the metal to be processed is in the second hot air channel and the second cold air channel, the placement platform moves into the groove of the baffle to isolate the first and second chambers. During processing, this prevents hot air or cold air from the first chamber from entering the second chamber and causing damage to the multi-stage electric telescopic cylinder, thus improving the service life of the multi-stage electric telescopic cylinder.

[0020] 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.

[0021] Please see Figure 1-5This utility model provides a technical solution: an annealing furnace for metal processing, including a base 14, a furnace body 1 mounted on the base 14, a baffle 9 inside the furnace body 1, a first chamber 8 above the baffle 9, a first hot air channel 4 and a first cold air channel 6 inside the first chamber 8, a plurality of second hot air channels 5 on the first hot air channel 4, a plurality of second cold air channels 7 on the first cold air channel 6, a hot air blower 2 and a cold air blower 3 mounted on the furnace body 1, and the first hot air channel 4 and the first cold air channel 6... The second hot air channel 5 is provided with a plurality of first exhaust holes 15, and the second cold air channel 7 is provided with a plurality of second exhaust holes 16. A second chamber 10 is provided below the baffle 9. A support plate 18 is movably arranged in the second chamber 10. A multi-stage electric telescopic cylinder 13 is provided on the upper wall of the support plate 18. A placement platform 12 is provided on the telescopic end of the multi-stage electric telescopic cylinder 13. A groove is provided on the baffle 9. The placement platform 12 is movably arranged in the groove of the baffle 9.

[0022] The placement table 12 is used to place the metal to be processed;

[0023] The multi-stage electric telescopic cylinder 13 is driven to extend and retract, thereby raising and lowering the placement table 12. The placement table 12 is movably set in the groove of the baffle 9. When the metal to be processed is in the second hot air channel 5 and the second cold air channel 7, the placement table 12 moves into the groove of the baffle 9 to isolate the first chamber 8 and the second chamber 10. During the processing, the hot air or cold air in the first chamber 8 can be prevented from entering the second chamber 10, which would cause damage to the multi-stage electric telescopic cylinder 13, thereby improving the service life of the multi-stage electric telescopic cylinder 13.

[0024] In this embodiment, the furnace body 1 is provided with a pair of sliding grooves 17, and the support plate 18 is provided with a pair of sliders 22. The support plate 18 is slidably installed in the sliding grooves 17 through the sliders 22.

[0025] The support plate 18 is slidably mounted in the slide groove 17 via the slider 22, which is used to control the moving direction of the support plate 18.

[0026] In this embodiment, the furnace body 1 is further configured with an insert block 25, a cavity is provided inside the furnace body 1, a stop block 21 is provided on the insert block 25 and located in the cavity of the furnace body 1, a spring 20 is provided on the insert block 25, a handle 19 is provided on the insert block 25, and a first limiting groove 23 and a second limiting groove 24 are provided on one of the sliders 22, and the insert block 25 is movably disposed in the first limiting groove 23 and the second limiting groove 24;

[0027] The drive handle 19 moves, causing the insert block 25 to move away from the first limiting groove 23 or the second limiting groove 24. The control block 21 moves, and the block 21 compresses the spring 20, causing the spring 20 to generate elastic force. The handle 19 is released, and the interaction force generated by the spring 20 drives the block 21 to move, thereby causing the insert block 25 to move into the first limiting groove 23 or the second limiting groove 24 for fixing the support plate 18.

[0028] In this embodiment, the second hot air channel 5 and the second cold air channel 7 are annular pipes, and the second hot air channel 5 and the second cold air channel 7 are arranged alternately in the first chamber 8.

[0029] The second hot air channel 5 and the second cold air channel 7 are arranged alternately in the first chamber 8. The second hot air channel 5 and the second cold air channel 7 are located around the metal to be processed. During the production process, the entire metal to be processed can be heated or cooled at the same time, thereby improving the production quality of the annealing furnace.

[0030] In this embodiment, a protective door 11 is further configured to be hinged to the furnace body 1.

[0031] Example: When placing the metal to be processed, open the protective door 11, drive the handle 19 to move, causing the insert 25 to move away from the second limiting groove 24. Pull the support plate 18 to move the insert 25 away from the second limiting groove 24. At the same time, release the handle 19, and the insert 25 moves to the first limiting groove 23. The interaction force generated by the spring 20 drives the stop block 21 to move, thereby moving the insert 25 into the first limiting groove 23 to fix the support plate 18 and also to limit it, preventing the support plate 18 from detaching from the furnace body 1. The support plate 18 can be moved outside the furnace body 1, making it easier for workers to place the metal to be processed. The metal to be processed is placed on the placement table 12, thereby improving the installation efficiency of the metal to be processed. When the annealing furnace is in use, the drive handle 19 is moved, which moves the insert block 25 away from the first limiting groove 23, pushing the support plate 18 and moving the insert block 25 away from the first limiting groove 23. At the same time, the handle 19 is released, and the insert block 25 moves to the second limiting groove 24. The interaction force generated by the spring 20 drives the stop block 21 to move, thereby moving the insert block 25 into the second limiting groove 24 to fix the support plate 18 and also to play a positioning role. At this time, the placement table 12 is in the groove of the baffle 9, which facilitates the operation of the workers. The operator moves the placement table 12 into the groove of the baffle 9, drives the multi-stage electric telescopic cylinder 13 to extend and retract, and drives the placement table 12 to rise and fall. The placement table 12 is movably set in the groove of the baffle 9. When the metal to be processed is in the second hot air channel 5 and the second cold air channel 7, the placement table 12 moves into the groove of the baffle 9 to isolate the first chamber 8 and the second chamber 10. During the processing, this can prevent the hot air or cold air in the first chamber 8 from entering the second chamber 10 and causing damage to the multi-stage electric telescopic cylinder 13, thereby improving the service life of the multi-stage electric telescopic cylinder 13. This drives the hot air blower 2 to start, and the hot air blower 2 produces... The hot air enters the second hot air channel 5 through the first hot air channel 4, and then heats the metal to be processed through the first exhaust hole 15. This drives the cold air blower 3 to start. The cold air generated by the cold air blower 3 enters the second cold air channel 7 through the first cold air channel 6, and then cools the metal to be processed through the second exhaust hole 16. The second hot air channel 5 and the second cold air channel 7 are arranged alternately in the first chamber 8. The second hot air channel 5 and the second cold air channel 7 are located around the metal to be processed. During the production process, the entire metal to be processed can be heated or cooled at the same time, thereby improving the production quality of the annealing furnace.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
