Description

Technical Field

[0001] This utility model relates to the field of metal forging processing technology, and in particular to a metal forging heating device. Background Technology

[0002] Forgings are workpieces or blanks obtained by forging and deforming metal billets. By applying pressure to the metal billet, plastic deformation is caused, which can change its mechanical properties. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the billet during processing. Cold forging is generally processed at room temperature, while hot forging is processed at a temperature higher than the recrystallization temperature of the metal billet.

[0003] Chinese patent document CN218015571U discloses a multi-functional heating furnace for high-precision metal forgings. This design solves the problem that when multiple metal forgings are in contact and piled up inside the furnace, the contact surfaces cannot be fully heated due to the fixed positions of the forgings, resulting in low utilization of the heating chamber's aperture and affecting the forging processing efficiency. The furnace includes a furnace body with a door rotatably connected to one side. Heating lamps are symmetrically arranged on the inner wall of the furnace body. An installation column is located inside the furnace body, and a sealing plate is installed on one side of the installation column. Both the installation column and the sealing plate have threaded holes. This design facilitates the longitudinal arrangement of metal forgings within the furnace body, solving the problem of uneven heating of the contact surfaces caused by metal forgings piling up at the bottom of the furnace body's inner cavity, while also improving the longitudinal utilization of the furnace body's internal space.

[0004] While the aforementioned patent documents can improve the longitudinal utilization rate of the internal space of the heating furnace body during implementation, they cannot ensure a uniform temperature distribution within the heating furnace cavity, resulting in uneven heating of various parts of the metal forging and affecting the heating efficiency of the metal forging. Utility Model Content

[0005] The main purpose of this invention is to provide a metal forging heating device that can effectively solve the problem of uneven temperature distribution in the heating furnace cavity.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A metal forging heating device includes a heating furnace body. A door is rotatably connected to the left front end of the outer surface of the heating furnace body. An air supply component is fixedly installed on the rear upper part of the outer surface of the heating furnace body. An exhaust mechanism is fixedly connected to the middle rear end of the outer surface of the heating furnace body. A heating lamp is fixedly installed on the top wall of the inner cavity of the heating furnace body. A heat conduction mechanism is fixedly connected to the bottom wall of the inner cavity of the heating furnace body. A bearing mechanism is symmetrically fixedly connected inside the heat conduction mechanism. Temperature sensors are symmetrically installed on the upper left and right sides inside the heat conduction mechanism. Ventilation mechanisms are symmetrically fixedly connected to the upper left and right sides of the heat conduction mechanism.

[0008] Preferably, the air supply assembly includes a blower, and an air supply bend is fixedly connected to the rear output end of the blower.

[0009] Preferably, the heat-conducting mechanism includes a U-shaped heat-conducting frame, wherein the left and right walls of the inner cavity of the U-shaped heat-conducting frame are symmetrically provided with receiving cavities that communicate with the outside.

[0010] Preferably, the bearing mechanism includes two connecting steel plates, and the inner cavities of the two connecting steel plates are fixedly connected to a bearing frame. The upper surface of the outer surface of the bearing frame is provided with a plurality of through holes that communicate with the outside.

[0011] Preferably, the ventilation mechanism includes a ventilation bend, with a jet nozzle fixedly connected to the upper end of the outer surface of the ventilation bend, and the lower part of the outer surface of the ventilation bend is fixedly connected to the upper front side of the U-shaped heat-conducting frame, and the lower open end of the ventilation bend communicates with the inner cavity of the U-shaped heat-conducting frame.

[0012] Preferably, the exhaust mechanism includes an air collecting sleeve, and the front of the outer surface of the air collecting sleeve is provided with a plurality of rectangular exhaust ports that communicate with the outside. The input end of the rear surface of the air collecting sleeve is fixedly connected to the output end of the lower part of the air supply bend.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model can achieve the function of supplying air to the interior of the exhaust mechanism through the air supply component. The exhaust mechanism can make the air in the inner cavity of the heating furnace body flow evenly. At the same time, the heat conduction mechanism can absorb the heat emitted by the heating lamp tube. Under the action of the bearing mechanism, the metal forging can be supported. Furthermore, the ventilation mechanism can connect the air in the inner cavity of the heating furnace body with the outside, thus improving the practicality and versatility of the device.

[0015] 2. This utility model, by driving a blower, allows the air inside the gas collecting sleeve to be evenly blown out into the inner cavity of the heating furnace body through several rectangular exhaust ports. This ensures that the hot air inside the heating furnace body flows evenly, and allows the hot air inside the heating furnace body to come into even and sufficient contact with the metal forgings placed on the upper part of the corresponding support frame through several through holes. This ensures that all parts of the metal forgings are heated evenly, improving the practicality and versatility of the device. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1As shown, a metal forging heating device includes a heating furnace body 1. A door 2 is rotatably connected to the left front end of the outer surface of the heating furnace body 1. An air supply component 3 is installed and fixed at the rear upper end of the outer surface of the heating furnace body 1, which can supply air to the interior of the exhaust mechanism 4. An exhaust mechanism 4 is fixedly connected to the middle rear end of the outer surface of the heating furnace body 1, which can ensure uniform airflow inside the heating furnace body 1. A heating lamp 5 is installed and fixed on the top wall of the inner cavity of the heating furnace body 1. A heat conduction mechanism 6 is fixedly connected to the bottom wall of the inner cavity of the heating furnace body 1, which can absorb the heat emitted by the heating lamp 5. A bearing mechanism 7 is symmetrically fixedly connected inside the heat conduction mechanism 6, which can support the metal forging. Temperature sensors 8 are symmetrically installed and fixed on the upper left and right sides of the heat conduction mechanism 6. Ventilation mechanisms 9 are symmetrically fixedly connected to the upper left and right sides of the heat conduction mechanism 6, which can connect the air inside the heating furnace body 1 with the outside.

[0023] To achieve the purpose of supplying air to the interior of the exhaust system 4, please refer to... Figure 2 The air supply assembly 3 includes a blower 31, and an air supply bend 32 is fixedly connected to the rear output end of the blower 31, which can realize the function of continuously supplying air to the inner cavity of the air collection sleeve 41.

[0024] In order to absorb the heat emitted by the heating lamp 5, please refer to... Figure 2 The heat conduction mechanism 6 includes a U-shaped heat conduction frame 61, which can effectively absorb and conduct the heat emitted by the heating lamp tube 5. The left and right walls of the inner cavity of the U-shaped heat conduction frame 61 are symmetrically provided with receiving cavities 62 that communicate with the outside, which can facilitate the installation and positioning of the corresponding connecting steel plate 71.

[0025] To achieve the purpose of bearing load on metal forgings, see [reference]. Figure 3 The bearing mechanism 7 includes two connecting steel plates 71, and the inner cavity of the two connecting steel plates 71 is fixedly connected to a bearing frame 72. The upper part of the outer surface of the bearing frame 72 is provided with several through holes 73 that communicate with the outside.

[0026] The heat emitted by the heating lamp tube 5 will be effectively absorbed by the U-shaped heat-conducting frame 61, and then the heat will be conducted to the support frame 72 through the connecting steel plate 71, so that the metal forging placed on the upper part of the support frame 72 will heat up quickly. At the same time, through several through holes 73, the hot air can be evenly and effectively contacted with the lower surface of the metal forging, so that the metal forging can be heated quickly and comprehensively.

[0027] To achieve the goal of connecting the air inside the heating furnace body 1 with the outside environment, refer to... Figure 3The ventilation mechanism 9 includes a ventilation bend 91, with a jet nozzle 92 fixedly connected to the upper end of the outer surface of the ventilation bend 91, and the lower part of the outer surface of the ventilation bend 91 fixedly connected to the upper front side of the U-shaped heat-conducting frame 61. The lower open end of the ventilation bend 91 communicates with the inner cavity of the U-shaped heat-conducting frame 61.

[0028] When the hot air inside the furnace body 1 reaches the rated volume, it can be discharged to the outside through the two ventilation bends 91, thus avoiding the danger of excessive air pressure inside the furnace body 1.

[0029] To achieve uniform airflow within the furnace body 1, refer to... Figure 4 The exhaust mechanism 4 includes an air collection housing 41. Several rectangular exhaust ports 42 that communicate with the outside are distributed at intervals on the front of the outer surface of the air collection housing 41. The input end of the rear surface of the air collection housing 41 is fixedly connected to the output end of the lower part of the air supply bend 32.

[0030] The air entering the inner cavity of the gas collecting sleeve 41 will be discharged through several rectangular exhaust ports 42. During this process, the air volume delivered by the blower 31 should not be too large, but only enough to allow the air discharged from the openings of the several rectangular exhaust ports 42 to cause a certain degree of flow of hot air in the inner cavity of the heating furnace body 1.

[0031] It should be noted that the temperature sensor 8 in this utility model is model MKD090B-058-KO1-KN, and the blower 31 is model T4-72. The specific installation method, circuit connection method and control method of the temperature sensor 8 and the blower 31 are all conventional designs, and this utility model will not describe them in detail.

[0032] The working principle of this utility model is as follows: After the metal forging is placed on the upper part of the support frame 72, the door 2 is closed and the heating lamp 5 is turned on, so that the heating lamp 5 heats the air in the inner cavity of the heating furnace body 1. When the temperature of the inner cavity of the heating furnace body 1 is detected by two temperature sensors 8 to reach the required value, the blower 31 is driven to supply air to the inner cavity of the gas collecting sleeve 41, so that the air in the inner cavity of the gas collecting sleeve 41 is discharged from the openings of several rectangular exhaust ports 42, thereby making the hot air in the inner cavity of the heating furnace body 1 flow evenly, and thus making the hot air in the inner cavity of the heating furnace body 1 heat the metal forging in a consistent manner.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
