[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" 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.

[0026] Please see Figure 1-7 This utility model provides a punching machine for the production of power distribution cabinets, including a machine body 1. Support rods 2 are fixedly connected to the four corners of the top wall of the machine body 1. A top plate 3 is fixedly connected between the upper ends of the four support rods 2. A hydraulic cylinder 4 is installed at the center of the upper side wall of the top plate 3. A lifting plate 5 is slidably arranged between the four support rods 2. The telescopic end of the hydraulic cylinder 4 passes through the top plate 3 and is fixedly connected to the lifting plate 5. The telescopic end of the hydraulic cylinder 4 can drive the lifting plate 5 to move up and down. A mounting base is fixedly connected at the center of the lower side wall of the lifting plate 5. 6. The mounting base 6 has a mounting groove 61, and the upper punch 7 is installed in the mounting groove 61. The upper side wall of the mounting groove 61 has a heat dissipation cavity 62, and a heat conduction plate 63 is fixedly connected in the heat dissipation cavity 62. The upper side wall of the heat conduction plate 63 is fixedly connected to the heat dissipation fins 64. When punching, the heat of the punch 7 will be conducted to the heat dissipation fins 64 through the heat conduction plate 63, and then the heat dissipation fins 64 will be cooled by liquid cooling mechanism 8. The upper side wall of the lifting plate 5 is provided with liquid cooling mechanism 8 and the lower side wall is provided with pressing mechanism 9.

[0027] Specifically, such as Figures 4 to 6As shown, a punching machine for producing electrical distribution cabinets includes a liquid cooling mechanism 8 comprising a liquid storage tank 81, a semiconductor cooling chip 82, cooling fins 83, a circulating pump 84, an inlet pipe 85, a drain pipe 86, a heat absorption pipe 87, and a return pipe 88. The liquid storage tank 81 is fixedly connected to the rear of the upper side wall of the lifting plate 5. The semiconductor cooling chip 82 is installed on the upper outer wall of the liquid storage tank 81, and the cooling fins 83 are installed on the upper inner wall of the liquid storage tank 81. The cooling fins 83 are in contact with the cold surface of the semiconductor cooling chip 82. The circulating pump 84 is also installed on the liquid storage tank 81, and its inlet is connected to the liquid storage tank 81 via the inlet pipe 85. A heat absorption pipe 87 is provided on the mounting base 6, and the heat absorption pipe 87 is inserted between the heat dissipation fins 64. The output port of the heat sink 87 is connected to one end of the heat absorption tube 87 via the drain pipe 86, and the other end of the heat absorption tube 87 is connected to the liquid storage tank 81 via the return pipe 88. The cold surface of the semiconductor cooling chip 82 cools the liquid, causing the cooling fins 83 to conduct the low temperature to the liquid storage tank 81, thus cooling the coolant in the liquid storage tank 81. The circulation pump 84 uses the inlet pipe 85 to draw out the coolant from the liquid storage tank 81 and transports the coolant to the heat absorption tube 87 through the drain pipe 86. When the coolant passes through the heat absorption tube 87, it will carry away the heat from the heat dissipation fins 64, and then flow back to the liquid storage tank 81 through the return pipe 88 for cooling, forming a cycle. This can continuously cool the die 7, avoid problems such as deformation caused by high temperature, and improve the service life of the die 7.

[0028] Specifically, such as Figure 2 and Figure 7 As shown, a punching machine for producing electrical distribution cabinets includes a clamping mechanism 9 comprising a sleeve 91, a movable plate 92, a push rod 93, a pressure plate 94, and a spring 95. A sleeve 91 is fixedly connected to the lower side wall of the lifting plate 5, located on both the front and rear sides of the mounting base 6. A movable plate 92 is slidably disposed within the sleeve 91. A push rod 93 is fixedly connected to the lower side wall of the movable plate 92. The lower end of the push rod 93 extends to the outside of the sleeve 91 and is fixedly connected to the pressure plate 94. A spring 95 abuts against the upper inner wall of the movable plate 92. When the lifting plate 5 moves downward, the pressure plate 94 contacts the metal plate before the punching die 7. As the lifting plate 5 continues to move downward, the push rod 93 pushes against the movable plate 92 and moves upward, forcing the spring 95 to contract. Under the rebound force of the spring 95, the pressure plate 94 can continuously press the metal plate, preventing the metal plate from shaking during punching and improving the punching accuracy.

[0029] Specifically, such as Figure 6 As shown, a punching machine for producing power distribution cabinets has a heat sink installed on the hot surface of a semiconductor cooling chip 82. The heat sink can dissipate heat from the hot surface of the semiconductor cooling chip 82 to ensure its normal operation.

[0030] Specifically, such as Figure 2As shown, a punching machine for producing distribution cabinets has a rubber pad 941 on the bottom wall of the pressure plate 94. The rubber pad 941 can prevent the pressure plate 94 from causing indentations on the metal plate and can increase friction, making the metal plate less prone to shaking.

[0031] Specifically, such as Figure 6 As shown, a punching machine for producing power distribution cabinets has a liquid inlet on the upper outer wall of the liquid storage tank 81, through which coolant is added into the liquid storage tank 81.

[0032] It should be noted that this utility model is a punching machine for the production of power distribution cabinets. In use, the metal plate of the power distribution cabinet is placed above the machine body 1. The telescopic end of the hydraulic cylinder 4 pushes the lifting plate 5 downwards. The pressure plate 94 contacts the metal plate before the punching die 7. As the lifting plate 5 continues to move downwards, the push rod 93 pushes the movable plate 92 upwards, forcing the spring 95 to contract. Under the rebound force of the spring 95, the pressure plate 94 can continuously press the metal plate until the punching die 7 completes the punching of the metal plate. During the punching process, the cold side of the semiconductor cooling chip 82 is cooled. The cooling fins 83 conduct low temperature to the liquid storage tank 81, cooling the coolant in the tank. The circulating pump 84 uses the inlet pipe 85 to extract the coolant from the tank 81 and sends it to the heat absorption pipe 87 through the outlet pipe 86. When the coolant passes through the heat absorption pipe 87, it carries away the heat from the heat dissipation fins 64 and then flows back to the liquid storage tank 81 through the return pipe 88 for cooling, forming a cycle. This continuously cools the die 7, preventing deformation caused by high temperature and improving the service life of the die 7.

[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.
