Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment, specifically to a temperature uniform control furnace for heat treatment of silicon steel sheets. Background Technology

[0002] The main heat treatment process for silicon steel sheets is annealing. Its purpose is to improve the properties of the silicon steel sheets, particularly their magnetic and processing properties, through heating, holding, and slow cooling. Annealing is an indispensable process step in silicon steel sheet production and is of great significance for improving product quality and performance.

[0003] During the annealing process of silicon steel sheets, the sheets need to be heated in a heat treatment furnace before being slowly cooled. Current processing methods involve directly stacking the silicon steel sheets inside the furnace, using spacers to separate them. However, the innermost sheets do not receive uniform heating, and the spacers must be removed one by one when unloading the sheets, resulting in slow unloading efficiency. Therefore, those skilled in the art have provided a temperature-uniform control furnace for the heat treatment of silicon steel sheets to solve the problems mentioned in the background. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a temperature uniform control furnace for heat treatment of silicon steel sheets, including a furnace body, and a movable seat is slidably connected to the lower part of the furnace body.

[0005] The movable seat includes a base, a limiting rod is fixedly connected to the top of the base, a movable plate is slidably connected to both sides of the limiting rod, a rotating shaft is rotatably connected inside the movable plate, multiple spacer rods are rotatably connected above the movable plate, the rotating shaft passes through the spacer rods, a round hole is provided below the spacer rod, a second protrusion is fixedly connected inside the round hole, a first protrusion is fixedly connected to the outside of the rotating shaft, the first protrusion is located on one side of the second protrusion, and an insertion hole is provided at one end of the rotating shaft.

[0006] Preferably, multiple heating components are installed on both sides and the top of the furnace body.

[0007] Preferably, a gantry frame is fixedly installed at both ends of the front side of the furnace body, and a closed door is slidably connected to the gantry frame, which can fit against the front side of the furnace body.

[0008] Preferably, a connecting plate is fixedly connected to the front side of the base, and multiple sets of rollers are installed under the base.

[0009] Preferably, a plurality of pull rods are fixedly connected to one side of the movable plate.

[0010] Preferably, the spacer is tilted to one side.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model incorporates a spacer bar, which vertically separates multiple silicon steel sheets, preventing uneven heating of the inner silicon steel sheets and improving the yield rate during heat treatment.

[0013] 2. This utility model is designed with rotatable spacer bars, which can be lowered sequentially when unloading silicon steel sheets, making unloading convenient. Furthermore, the rotating shaft can be used to lower all the spacer bars on one side first, so that only one side of the spacer bars needs to be rotated during unloading, further improving unloading efficiency.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-3 In this embodiment, a temperature uniform control furnace for heat treatment of silicon steel sheets is provided, including a furnace body 1, and a movable seat 4 is slidably connected to the lower part of the furnace body 1.

[0024] The movable base 4 includes a base 41, a limiting rod 44 fixedly connected above the base 41, a movable plate 45 slidably connected to both sides of the limiting rod 44, a rotating shaft 47 rotatably connected inside the movable plate 45, a plurality of spacer rods 48 rotatably connected above the movable plate 45, the rotating shaft 47 passes through the spacer rods 48, a round hole is provided below the spacer rods 48, a second protrusion 481 is fixedly connected inside the round hole, a first protrusion 471 is fixedly connected to the outside of the rotating shaft 47, the first protrusion 471 is located on one side of the second protrusion 481, and an insertion hole 472 is provided at one end of the rotating shaft 47.

[0025] In use, silicon steel sheets are placed between the spacers 48 above the moving plate 45. The spacers 48 vertically separate multiple silicon steel sheets to prevent uneven heating during heating. When removing the silicon steel sheets, the spacers 48 are rotated so that they are horizontally positioned between the moving plates 45, allowing the silicon steel sheets between the spacers 48 to be removed sequentially. A lever inserted into the insertion hole 472 drives the rotating shaft 47 to rotate. The rotating shaft 47 drives the first protrusion 471 to rotate, pushing the second protrusion 481 to rotate. The second protrusion 481 drives the spacers 48 to rotate and lower, thus allowing one side of the spacers 48 to be lowered together before unloading, improving unloading efficiency.

[0026] In this embodiment, specifically, multiple heating components are installed on both sides and the top of the furnace body 1. The silicon steel sheets are heated by these heating components.

[0027] In this embodiment, specifically, a gantry frame 2 is fixedly installed at both ends of the front side of the furnace body 1, and a sealing door 3 is slidably connected to the gantry frame 2. The sealing door 3 can fit against the front side of the furnace body 1. The furnace body 1 is sealed by the sealing door 3.

[0028] In this embodiment, specifically, a connecting plate 42 is fixedly connected to the front side of the base 41, and multiple sets of rollers 43 are installed below the base 41. A traveling mechanism is connected through the connecting plate 42, and the traveling mechanism pulls the base 41 out from under the furnace body 1 for easy loading and unloading of silicon steel sheets.

[0029] In this embodiment, specifically, a plurality of pull rods 46 are fixedly connected to one side of the movable plate 45. The movable plate 45 can be moved by pulling the pull rods 46, and the spacing of the movable plate 45 can be adjusted according to the size of the silicon steel sheet.

[0030] In this embodiment, specifically, the spacer 48 is tilted to one side. This ensures that during movement, the spacer 48 will not tip over on its own and thus lose support for the silicon steel sheet.

[0031] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
