[0002] Heaters are common household appliances used in winter, mainly for heating local or small spaces to provide a warm and comfortable environment. In the manufacturing of heaters, the punching of the outer shell is a key step. By reasonably designing the hole shape (such as round hole, diamond hole, elongated hole) and hole spacing, the air convection efficiency can be improved.

[0003] However, in the use of existing punching devices, the inside of the outer shell is usually hollow. During the punching process, the surface of the outer shell is subjected to excessive pressure, which may cause local deformation of the outer shell, thereby reducing the overall structural strength of the outer shell and affecting its appearance. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the interior of the casing is usually hollow during the use of the punching device. During the punching process, the surface of the casing is subjected to excessive pressure, which may cause local deformation of the casing, thereby reducing the overall structural strength of the casing and affecting its appearance. This utility model proposes a casing punching device for heater processing.

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a punching device for the outer shell of a heater. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 5 A punching device for the outer shell of a heater includes a punching box 1. A positioning seat 3 is fixedly connected to the bottom of the inner cavity of the punching box 1. The top of the positioning seat 3 contacts the outer shell of the heater 4. A moving component 5 is installed on the top of the punching box 1. The moving component 5 consists of a moving guide rail and a cylinder. It is driven to move horizontally by the moving guide rail and to move vertically by the cylinder. A fixing plate 6 is installed at the bottom of the moving component 5. A punch 7 is installed at the bottom of the fixing plate 6. Clamping plates 8 are fixedly connected to both sides of the bottom of the fixing plate 6. A support mechanism 2 is installed in the inner cavity of the punching box 1. The support mechanism 2 includes a motor 209. The front side of the motor 209 is fixedly connected to the back side of the punch box 1. A gear 208 is fixedly connected to the output end of the motor 209. A toothed plate 207 is meshed with the bottom of the surface of the gear 208. A movable plate 204 is fixedly connected to the bottom of the toothed plate 207. A connecting plate 206 is fixedly connected to the left side of the movable plate 204. A support frame 202 is fixedly connected to the left side of the connecting plate 206. The surface of the support frame 202 is slidably connected to the inner cavity of the heater shell 4.

[0018] Reference Figure 1 and Figure 3A support rod 203 is slidably connected to the inner cavity of the movable plate 204. The surface of the support rod 203 is fixedly connected to the inner cavity of the punching box 1. The support rod 203 supports the position of the movable plate 204, improves the stability of the movable plate 204 during movement, and prevents the position of the movable plate 204 from shifting during movement.

[0019] Reference Figure 3 and Figure 4 A support plate 212 is movably connected to the top of the inner cavity of the support frame 202. There are several support plates 212 arranged in multiple rows. The top of the support plate 212 contacts the top of the inner cavity of the heater shell 4. By setting the support plate 212, the contact area with the inside of the heater shell 4 is increased, thereby improving the support effect on the inside of the heater shell 4.

[0020] Reference Figure 3 and Figure 4 The top of the support frame 202 is provided with a positioning groove 213. The positioning plate 211 is engaged in the inner cavity of the positioning groove 213. One side of the positioning plate 211 is fixedly connected to the surface of the support plate 212. By setting the positioning groove 213, the surface of the positioning plate 211 can be engaged into the interior of the support frame 202, thereby fixing the position of the support plate 212 and ensuring the stability of the support plate 212 during use.

[0021] Reference Figure 3 and Figure 4 A positioning rod 210 is fixedly connected to the inner cavity of the positioning groove 213. The surface of the positioning rod 210 is inserted into the inner cavity of the positioning plate 211. The positioning rod 210 is used to position the positioning plate 211 and prevent the positioning plate 211 from shifting during use, thus preventing the positioning plate 211 from detaching from the inside of the positioning groove 213 during use.

[0022] Reference Figure 2 The right side of the punching box 1 is provided with a movable groove 205. The inner cavity of the movable groove 205 is slidably connected to the surface of the movable plate 204. Through the setting of the movable groove 205, the surface of the movable plate 204 can enter and exit the interior of the punching box 1, thereby allowing the support frame 202 to be stored in place. This prevents the support frame 202 from being too close to the heater housing 4 when not in use, thus affecting the normal handling and placement of the heater housing 4.

[0023] Reference Figure 1 and Figure 2A protective cover 201 is fixedly connected to the right side of the punching box 1. The inner cavity of the protective cover 201 is fitted onto the surface of the movable plate 204. The protective cover 201 protects the exposed surface of the movable plate 204, preventing the external part of the movable plate 204 from being hit by external objects, which would damage the surface of the movable plate 204 and affect its subsequent normal use.

[0024] Working principle: First, the heater housing 4, which needs to be punched, is placed on top of the positioning seat 3. After the heater housing 4 is placed, the motor 209 is started by an external power source. The motor 209 drives the gear 208 to rotate, which in turn moves the gear plate 207. The movement of the gear plate 207 moves the moving plate 204, which in turn moves the connecting plate 206. The movement of the connecting plate 206 moves the support frame 202 until the surface of the support frame 202 enters the interior of the heater housing 4, thereby supporting the interior of the heater housing 4. Then, the fixed plate 6 is driven to move downward by the moving component 5. The movement of the fixed plate 6 drives the punch 7 and the clamping plate 8 to move synchronously. During the movement of the fixed plate 6, the clamping plate 8 will first contact the surface of the heater shell 4. Through the cooperation of the clamping plate 8 and the positioning seat 3, the heater shell 4 can be clamped and fixed. Subsequently, when the fixed plate 6 continues to move, the bottom of the punch 7 will contact the surface of the heater shell 4, thus completing the punching of the surface of the heater shell 4. Afterward, the fixed plate 6 is driven to move back and forth or left and right inside the punching box 1 by the moving component 5, so that the surface of the heater shell 4 can be punched as needed.

[0025] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0026] 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 claimed utility model.
