This results in variations in the heating of metal parts, affecting the consistency of material properties after heat treatment and making it difficult to quench metal workpieces uniformly and effectively in a timely manner, thus impacting processing efficiency. Therefore, improvements are needed. This paper proposes a quenching furnace for metal heat treatment. Utility Model Content

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7 This utility model provides a technical solution:

[0029] A quenching furnace for metal heat treatment includes a furnace body 1, a cover plate 2 on one side of the furnace body 1, symmetrical support plates 3 fixedly installed on the inner wall of the furnace body 1, a crossbar 4 rotatably installed in the middle of the furnace body 1, uniformly distributed blades 5 fixedly installed on the crossbar 4, the blades 5 being disposed inside the furnace body 1, a motor 6 fixedly installed on the side of the furnace body 1 away from the cover plate 2, a symmetrical connecting rod 7 fixedly installed at the end of the output shaft of the motor 6, a connecting plate 8 fixedly installed at the end of the crossbar 4, the ends of both sets of connecting rods 7 being fixedly installed to the connecting plate 8, a liquid infusion pipe 9 fixedly installed on the side of the furnace body 1, a rotary joint 10 fixedly installed at the top of the liquid infusion pipe 9, both the crossbar 4 and the blades 5 being hollow, the rotating end of the rotary joint 10 being connected to the end of the crossbar 4, and uniformly distributed liquid outlets 11 being opened on the side of each blade 5.

[0030] When heat treating metal parts, the metal parts are first placed on the tray 3 inside the furnace body 1, and the cover 2 is closed. The furnace body 1 is then turned on, and the furnace body 1 starts to work and generate heat to heat the space inside the furnace, thereby heating the metal parts on the tray 3.

[0031] While the metal parts are being heated, the motor 6 starts. The output shaft of the motor 6 drives the connecting rod 7 to rotate. The rotation of the connecting rod 7 drives the connecting plate 8 to rotate. The rotation of the connecting rod 7 eventually drives the crossbar 4 and the blades 5 fixed on the crossbar 4 to rotate synchronously. During the heating process, the rotation of the blades 5 is like a fan, which makes the hot air in the furnace form a circulating airflow. The hot air is evenly delivered to the surface of the metal parts to ensure that the metal parts are heated evenly.

[0032] When the metal parts need to be quenched after heating, the quenching medium is delivered through the infusion pipe 9, enters the hollow crossbar 4 and blade 5 through the rotary joint 10, and finally sprays out from the outlet 11 evenly distributed on the side of the blade 5. Since the blade 5 rotates continuously under the drive of the motor 6, the quenching medium can be evenly sprayed on all parts of the metal parts to achieve a fast and uniform quenching operation.

[0033] The quenching furnace used in this metal heat treatment can not only heat the metal parts uniformly, but also quickly quench them uniformly, effectively improving the processing efficiency of the metal parts.

[0034] A drain pipe 12 is provided at the bottom side of the furnace body 1, and a drain pump 13 is provided on the drain pipe 12;

[0035] After the quenching process is completed, the drain pump 13 is started. The drain pump 13 generates suction, which causes the quenching medium in the furnace body 1 to be discharged from the furnace body 1 through the drain pipe 12 under the action of suction.

[0036] The furnace body 1 is provided with symmetrical slots 14, and the tray 3 is snapped onto the slots 14;

[0037] When installing the tray 3, align the tray 3 with the position of the slot 14 and then gently push it in. The shape and size of the slot 14 match the tray 3, so that the tray 3 can be stably fixed in the furnace body 1. When it is necessary to remove the tray 3, simply apply a certain amount of external force to pull the tray 3 out of the slot 14, which makes it easy to disassemble and assemble the tray 3.

[0038] The blades 5 on the crossbar 4 are provided with at least four sets that are evenly distributed;

[0039] The crossbar 4 has at least four sets of blades 5 evenly distributed. During heating, multiple sets of blades 5 rotate simultaneously, which can form a stronger and more uniform airflow. During quenching, the rotation of multiple sets of blades 5 can drive more quenching medium to be sprayed out from the liquid outlet 11, and make the quenching medium evenly dispersed over a larger area, which can improve the uniform heating effect and quenching effect of the metal parts.

[0040] The length of blade 5 is adapted to the inner diameter of the quenching furnace;

[0041] The length of blade 5 is matched with the inner diameter of the quenching furnace. During the heating process, when blade 5 rotates, it can maximize the circulation of hot air in the furnace throughout the cross-section of the furnace body 1, avoiding dead zones in airflow. This ensures that all parts of the metal parts can come into contact with a uniform flow of hot air, guaranteeing that the metal parts are heated evenly. During the quenching stage, when blade 5 rotates, it can evenly distribute the quenching medium sprayed from the outlet 11 throughout the entire furnace body 1. This prevents uneven quenching in certain areas due to the limited spray range of the quenching medium caused by blade 5 being too short, thus ensuring uniform heating and quenching of the metal parts.

[0042] A controller is provided on the side of the furnace body 1, and the controller is electrically connected to the furnace body 1, the motor 6, and the drain pump 13 respectively;

[0043] The controller can automatically control the heating and quenching process of metal parts.

[0044] Working principle:

[0045] When heat treating metal parts, the metal parts are first placed on the tray 3 inside the furnace body 1, and the cover 2 is closed. The furnace body 1 is then turned on, and the furnace body 1 starts to work and generate heat to heat the space inside the furnace, thereby heating the metal parts on the tray 3.

[0046] While the metal parts are being heated, the motor 6 starts. The output shaft of the motor 6 drives the connecting rod 7 to rotate. The rotation of the connecting rod 7 drives the connecting plate 8 to rotate. The rotation of the connecting rod 7 eventually drives the crossbar 4 and the blades 5 fixed on the crossbar 4 to rotate synchronously. During the heating process, the rotation of the blades 5 is like a fan, which makes the hot air in the furnace form a circulating airflow. The hot air is evenly delivered to the surface of the metal parts to ensure that the metal parts are heated evenly.

[0047] When the metal parts need to be quenched after heating, the quenching medium is delivered through the infusion pipe 9, enters the hollow crossbar 4 and blade 5 through the rotary joint 10, and finally sprays out from the outlet 11 evenly distributed on the side of the blade 5. Since the blade 5 rotates continuously under the drive of the motor 6, the quenching medium can be evenly sprayed on all parts of the metal parts to achieve a fast and uniform quenching operation.

[0048] After the quenching process is completed, the drain pump 13 is started. The drain pump 13 generates suction, which causes the quenching medium in the furnace body 1 to be discharged from the furnace body 1 through the drain pipe 12 under the action of suction.

[0049] The crossbar 4 has at least four sets of blades 5 evenly distributed. During heating, multiple sets of blades 5 rotate simultaneously, which can form a stronger and more uniform airflow. During quenching, the rotation of multiple sets of blades 5 can drive more quenching medium to be sprayed out from the liquid outlet 11, and make the quenching medium evenly dispersed over a larger area, which can improve the uniform heating effect and quenching effect of metal parts.

[0050] The length of blade 5 is matched with the inner diameter of the quenching furnace. During the heating process, when blade 5 rotates, it can maximize the circulation of hot air in the furnace throughout the cross-section of the entire furnace body 1, avoiding dead air flow and ensuring that all parts of the metal parts can come into contact with a uniform flow of hot air, thus ensuring that the metal parts are heated evenly. During the quenching stage, when blade 5 rotates, it can evenly distribute the quenching medium sprayed from the liquid outlet 11 throughout the entire furnace body 1, and will not cause uneven quenching in some areas due to the limited spray range of the quenching medium caused by blade 5 being too short. This ensures that the metal parts are heated and quenched evenly.

[0051] The controller can automatically control the heating and quenching process of metal parts;

[0052] The quenching furnace used in this metal heat treatment can not only heat the metal parts uniformly, but also quickly quench them uniformly, effectively improving the processing efficiency of the metal parts.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
