Description

Technical Field

[0001] The utility model belongs to the technical field of spring material heating, and particularly relates to a spring material heating device. Background Art

[0002] Spring materials refer to various metal materials used to manufacture springs. These materials need to have good elasticity, high fatigue strength, sufficient toughness and hardness, as well as good corrosion resistance and other physical and chemical properties. For example, carbon steel, alloy steel, stainless steel, copper alloy, nickel alloy, and titanium alloy, etc. During the spring production process, the spring materials need to be processed, and one of the main steps is heating. The purpose is to change the physical and chemical properties of the metal materials through heating, so as to improve the performance of the springs, such as strength, hardness, toughness, etc.

[0003] At present, box furnaces can achieve precise temperature control and time control, and are widely used in spring material heating and suitable for mass production. However, there is a high-temperature box furnace with the Chinese patent publication number CN219223253U: "Including: a box furnace, a box door is assembled on the front of the box furnace; a furnace body is embedded in the front of the box furnace, a heating cavity is opened on the front of the furnace body, and a plurality of heating rods are fixedly connected to the inner walls on both sides of the heating cavity; a support assembly is arranged inside the heating cavity; the support assembly includes a base and a plurality of partition bars, and the base is placed on the inner bottom wall of the heating cavity. In this high-temperature box furnace, through the provided support assembly, a plurality of sheet materials to be heated are respectively placed between a plurality of partition bars, and a plurality of heating rods heat the inside of the heating cavity, thereby heating a plurality of sheet materials simultaneously. Because the plurality of sheet materials are placed vertically and do not closely fit, uneven heating will not occur during the heating process."

[0004] It sets heating rods on both sides of the heating cavity, which will lead to uneven distribution of heating elements and uneven heat in the furnace, and easily cause uneven heating of spring materials.

[0005] Therefore, the existing spring material heating devices cannot meet the requirements in actual use, so there is an urgent need for improved technologies on the market to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a spring material heating device. By evenly arranging a plurality of first heating elements in a semi-surrounding manner inside the heat insulation layer and cooperating with the second heating elements evenly arranged in a semi-surrounding manner between the outer shell and the heat insulation layer, it solves the problem that setting heating rods on both sides of the heating cavity will lead to uneven distribution of heating elements, uneven heat in the furnace, and easily cause uneven heating of spring materials.

[0007] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0008] The present utility model is a heating device for spring materials, including a box furnace body. The box furnace body includes a housing, a heat insulation layer, and a plurality of first heating elements uniformly arranged inside the heat insulation layer. And a plurality of second heating elements are uniformly arranged between the heat insulation layer and the housing. By arranging a plurality of first heating elements in a semi - enclosed and uniform manner inside the heat insulation layer and cooperating with the second heating elements semi - enclosed and uniformly arranged between the housing and the heat insulation layer, the inside of the furnace chamber of the box furnace body is heated evenly.

[0009] Further, a through - hole is opened in the middle of the back of the box furnace body, and four support legs are uniformly fixed inside the furnace chamber of the box furnace body.

[0010] Further, a furnace chamber frame plate is fixed at the top of the four support legs. The furnace chamber frame plate is convenient for placing spring materials. By fixing the position of the furnace chamber frame plate through the support legs, the spring materials on the surface of the furnace chamber frame plate are located at the central position inside the furnace chamber of the box furnace body, ensuring uniform heating.

[0011] Further, a fixing rod is fixed on the outer side of the back of the box furnace body, and a rotating motor is fixed at one end of the fixing rod. The position of the rotating motor is fixed by the cooperation of the box furnace body and the fixing rod.

[0012] Further, a round rod is fixed at the output end of the rotating motor, and a fan blade group is fixed at one end of the round rod. By the operation of the rotating motor, the round rod and the fan blade group are driven to rotate. By the rotation of the fan blade group, the air inside the furnace chamber of the box furnace body is stirred and evenly mixed, ensuring uniform heating.

[0013] Further, the round rod penetrates through the through - hole and extends into the interior of the furnace chamber of the box furnace body. The position of the round rod is limited by the through - hole to prevent the round rod from shifting during rotation.

[0014] The present utility model has the following beneficial effects:

[0015] The present utility model heats the inside of the furnace chamber of the box furnace body evenly by arranging a plurality of first heating elements in a semi - enclosed and uniform manner inside the heat insulation layer and cooperating with the second heating elements semi - enclosed and uniformly arranged between the housing and the heat insulation layer. At the same time, a furnace chamber frame plate located at the center of the furnace chamber of the box furnace body is set to place spring materials, and the air inside the furnace chamber of the box furnace body is evenly mixed through the cooperation of the rotating motor, the round rod, and the fan blade group, further ensuring that the spring materials inside the furnace chamber of the box furnace body are heated evenly.
