Description
Technical Field
[0001] This application relates to the field of mechanical manufacturing technology, and in particular to a stamping die with a cooling function. Background Technology
[0002] Stamping dies are widely used tools in the manufacturing industry, primarily for forming and processing sheet metal. As the manufacturing industry's demands for product quality and production efficiency continue to increase, the performance of stamping dies directly affects the precision and consistency of products. Currently, stamping dies are prone to generating high temperatures during prolonged high-speed operation, leading to die deformation, accelerated wear, and even impacting product quality. To address this issue, the industry is continuously exploring various cooling technologies to improve the durability and stability of the dies.
[0003] Currently, common cooling technologies for stamping dies mainly include: 1. Cooling by external spraying of coolant; 2. Designing cooling channels inside the die; 3. Using air cooling technology. Among these, while external spraying of coolant is simple, the cooling effect is uneven and can easily cause production environment problems; while the design of internal cooling channels is more effective, it increases the complexity of the die and manufacturing costs; air cooling technology is low in cost, but its cooling efficiency is limited and cannot meet the needs of high-intensity production. Therefore, there is an urgent need for an efficient, uniform, and cost-effective cooling technology to solve the high temperature problem of stamping dies during long-term operation.
[0004] Therefore, this application provides a stamping die with a cooling function. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a stamping die with a cooling function, overcoming the deficiencies of the prior art. It aims to solve the problems of uneven cooling effect and potential environmental issues caused by external spraying of coolant, while internal cooling channels offer better performance but increase the complexity and manufacturing cost of the die. Air cooling technology is low-cost but has limited cooling efficiency, making it difficult to meet the demands of high-intensity production. Therefore, there is an urgent need for an efficient, uniform, and cost-effective cooling technology to address the high temperature problem of stamping dies during prolonged operation.
[0006] To achieve the above objectives, this application provides the following technical solution: a stamping die with a cooling function, comprising a lower die base and an upper die base, both of which have cooling channels inside. A water inlet pipe is fixedly installed on the top of both the lower and upper die bases, and a water outlet pipe is fixedly installed on the bottom of both the lower and upper die bases. A cooling medium circulation mechanism is provided between the lower and upper die bases, the cooling medium circulation mechanism including a coolant tank. The coolant tank is placed on one side of the lower die base, and a first water pump is fixedly installed on the top of the coolant tank. The first water pump pumps water... A water pump is connected to the coolant storage tank. A first tee connector is fixedly installed at the outlet end of the first water pump. A water inlet flexible hose is connected between the first tee connector and both sets of water inlet pipes. A second water pump is fixedly installed at the bottom of the coolant storage tank. A water delivery pipe is fixedly installed at the pumping end of the second water pump. A drain flexible hose is installed on one side of each of the two sets of water outlet pipes. A second tee connector is connected between the two sets of drain flexible hoses. The end of the water delivery pipe away from the second water pump is connected to the second tee connector. A heat dissipation mechanism is provided in the middle of the water delivery pipe.
[0007] By adopting the above technical solution, the lower die holder and the upper die holder are installed on the stamping machine. During the stamping process, the first water pump is started. The first water pump draws the cooling medium from the coolant storage tank through the water pumping pipe and disperses the cooling medium into two sets of water-filling telescopic hoses through the first tee joint. The cooling medium is then delivered to the cooling channels in the lower die holder and the upper die holder respectively. After flowing through the cooling channels, the cooling medium absorbs the heat from the lower die holder and the upper die holder, and then discharges it into the corresponding drain telescopic hoses through the water outlet pipe. At the same time, the second water pump is started, and the coolant returns to the coolant storage tank through the water supply pipe. When the coolant passes through the middle of the water supply pipe, it is cooled by the heat dissipation mechanism. Through the cooling medium circulation mechanism, the lower die holder and the upper die holder can maintain a suitable temperature during operation, avoiding deformation and wear caused by high temperature. At the same time, the structure of this application is simple and reduces manufacturing costs.
[0008] As a preferred technical solution of this application, the heat dissipation mechanism includes a heat dissipation box, which is fixedly installed on the outer surface of the water supply pipe. A fixing frame is fixedly installed in the middle of the heat dissipation box, and a bracket is fixedly installed in the middle of the fixing frame. A motor is fixedly installed on the side of the bracket near the heat dissipation box, and a fan is fixedly installed at the output end of the motor.
[0009] By adopting the above technical solution, the fan is driven to rotate through the heat sink to generate forced airflow, which carries away the heat in the heat sink and dissipates the heat of the cooling medium passing through the water pipe, effectively reducing the temperature of the cooling medium returning to the coolant storage tank.
[0010] As a preferred embodiment of this application, the cooling channel is spiral-shaped and the cooling channel is evenly arranged along the outer surface of the lower mold base.
[0011] By adopting the above technical solution, the spiral shape of the cooling channel extends the contact area between the cooling medium and the lower and upper mold bases, which is beneficial for the cooling medium to fully contact the surfaces of the lower and upper mold bases and improves the uniformity of cooling the lower and upper mold bases.
[0012] As a preferred technical solution of this application, a temperature sensor is fixedly installed at the cooling channel.
[0013] By adopting the above technical solution, the temperature of the lower die holder and the upper die holder can be monitored in real time by temperature sensors, which helps the staff to understand the temperature of the lower die holder and the upper die holder during the stamping process.
[0014] As a preferred technical solution of this application, a controller is fixedly installed on the top of the coolant storage tank, and the temperature sensor and the motor are both electrically connected to the controller.
[0015] By adopting the above technical solution, the controller receives the temperature data measured by the temperature sensor and adjusts the motor speed according to the temperature data measured by the temperature sensor. When the temperature is high, the motor speed is increased, and when the temperature is low, the motor speed is decreased, thereby controlling the heat dissipation effect of the cooling medium on the lower mold base and the upper mold base, and improving the automation level of the device.
[0016] As a preferred technical solution of this application, a number of heat dissipation fins are fixedly installed on the outer surface of the heat dissipation box.
[0017] By adopting the above technical solution, the heat dissipation area of the heat sink is increased by using heat dissipation fins, thereby improving the heat dissipation efficiency of the cooling medium passing through the water pipe.
[0018] As a preferred technical solution of this application, a liquid level observation window is fixedly installed at the bottom of the coolant storage tank.
[0019] By adopting the above technical solution, the liquid level observation window makes it easier for staff to check the remaining amount of cooling medium in the coolant storage tank, thus improving its practicality during use.
[0020] As a preferred embodiment of this application, a filling pipe is fixedly installed on the top of the coolant storage tank, and a sealing cap is fixedly installed on the top of the filling pipe.
[0021] By adopting the above technical solution, the cooling medium in the coolant storage tank can be easily replenished through the filling pipe. The coolant storage tank has a drain pipe at the bottom, and the filling pipe improves the sealing effect of the coolant storage tank.
[0022] The beneficial effects of this application are:
[0023] 1. The lower and upper die bases are installed on the stamping machine. During the stamping process, the first water pump is started. The first water pump draws the cooling medium from the coolant storage tank through the water pumping pipe and disperses the cooling medium into two sets of water-filling telescopic hoses through the first tee joint. The cooling medium is then delivered to the cooling channels in the lower and upper die bases respectively. After flowing through the cooling channels, the cooling medium absorbs the heat from the lower and upper die bases and is discharged into the corresponding drain telescopic hoses through the water outlet pipes. At the same time, the second water pump is started, and the coolant returns to the coolant storage tank through the water supply pipe. When the coolant passes through the middle of the water supply pipe, it is cooled by the heat dissipation mechanism. The cooling medium circulation mechanism helps the lower and upper die bases maintain a suitable temperature during operation, avoiding deformation and wear caused by high temperature. At the same time, the structure of this application is simple and reduces manufacturing costs.
[0024] 2. The fan is driven by the heat sink to rotate, generating forced airflow, which carries away the heat in the heat sink and dissipates the heat of the cooling medium passing through the water pipe, effectively reducing the temperature of the cooling medium returning to the coolant storage tank.

[0031] Reference Figure 1-4 A stamping die with cooling function includes a lower die base 1 and an upper die base 2. Cooling channels 3 are provided inside both the lower die base 1 and the upper die base 2. Water inlet pipes 4 are fixedly installed on the top of both the lower die base 1 and the upper die base 2, and water outlet pipes 5 are fixedly installed on the bottom of both the lower die base 1 and the upper die base 2. A cooling medium circulation mechanism 6 is provided between the lower die base 1 and the upper die base 2. The cooling medium circulation mechanism 6 includes a coolant storage tank 601, which is placed on one side of the lower die base 1. A first water pump 602 is fixedly installed on the top of the coolant storage tank 601. A water pumping pipe 603 connects the water pumping end of the first water pump 602 to the coolant storage tank 601. The water pumping outlet of the first water pump 602... A first tee connector 604 is fixedly installed at the end of the coolant tank 601. A water-filling telescopic hose 605 is connected between the first tee connector 604 and the two sets of water inlet pipes 4. A second water pump 606 is fixedly installed at the bottom of the coolant storage tank 601. A water supply pipe 607 is fixedly installed at the water pump end of the second water pump 606. A drain telescopic hose 609 is installed on one side of each of the two sets of water outlet pipes 5. A second tee connector 608 is connected between the two sets of drain telescopic hoses 609. The end of the water supply pipe 607 away from the second water pump 606 is connected to the second tee connector 608. A heat dissipation mechanism 7 is provided in the middle of the water supply pipe 607. The cooling channel 3 is spiral and is evenly arranged along the outer surface of the lower mold base 1.
[0032] The lower die holder 1 and upper die holder 2 are installed onto the stamping machine. During the stamping process, the first water pump 602 is started. The first water pump 602 draws the cooling medium from the coolant storage tank 601 through the water pumping pipe 603, and disperses the cooling medium into two sets of water-filling telescopic hoses 605 through the first tee connector 604, thereby delivering the cooling medium to the cooling channels 3 in the lower die holder 1 and upper die holder 2 respectively. After flowing through the cooling channels 3, the cooling medium absorbs the heat of the lower die holder 1 and upper die holder 2, and then discharges it into the corresponding drain telescopic hoses 609 through the water outlet pipes 5. At the same time, the second water pump 606 is started to cool... The coolant returns to the coolant storage tank 601 through the water pipe 607. When the coolant passes through the middle of the water pipe 607, it is cooled by the heat dissipation mechanism 7 and the cooling medium circulation mechanism 6. This helps the lower mold base 1 and the upper mold base 2 maintain a suitable temperature during operation, avoiding deformation and wear caused by high temperature. At the same time, the structure of this application is simple and reduces manufacturing costs. The cooling channel 3 is spiral, which extends the contact area between the cooling medium and the lower mold base 1 and the upper mold base 2. This helps the cooling medium to fully contact the surfaces of the lower mold base 1 and the upper mold base 2, improving the uniformity of cooling of the lower mold base 1 and the upper mold base 2.
[0033] Reference Figure 2-4 The heat dissipation mechanism 7 includes a heat dissipation box 701, which is fixedly installed on the outer surface of the water supply pipe 607. A fixing frame 702 is fixedly installed in the middle of the heat dissipation box 701, and a bracket 703 is fixedly installed in the middle of the fixing frame 702. A motor 704 is fixedly installed on the side of the bracket 703 near the heat dissipation box 701, and a fan 705 is fixedly installed at the output end of the motor 704. A temperature sensor 9 is fixedly installed at the cooling channel 3.
[0034] The fan 705 is driven by the heat sink 701 to rotate, generating forced airflow, which removes the heat in the heat sink 701 and dissipates the heat of the cooling medium passing through the water pipe 607, effectively reducing the temperature of the cooling medium returning to the coolant storage tank 601; the temperature sensor 9 monitors the temperature of the lower mold base 1 and the upper mold base 2 in real time, which is helpful for the staff to understand the temperature of the lower mold base 1 and the upper mold base 2 during the stamping process.
[0035] Reference Figure 2-4A controller 10 is fixedly installed at the top of the coolant storage tank 601, and the temperature sensor 9 and the motor 704 are electrically connected to the controller 10. A liquid level observation window 11 is fixedly installed at the bottom of the coolant storage tank 601. The controller 10 receives the temperature data measured by the temperature sensor 9 and adjusts the speed of the motor 704 according to the temperature data measured by the temperature sensor 9. When the temperature is high, the speed of the motor 704 is increased, and when the temperature is low, the speed of the motor 704 is decreased, thereby controlling the heat dissipation effect of the cooling medium on the lower mold base 1 and the upper mold base 2, and improving the automation level of the device. The liquid level observation window 11 makes it easy for the operator to check the remaining amount of cooling medium in the coolant storage tank 601, improving its practicality during use.
[0036] Reference Figure 2-4 The outer surface of the heat sink 701 is fixedly equipped with several sets of heat dissipation fins 8; the top of the coolant storage tank 601 is fixedly equipped with a liquid filling pipe 12, and the top of the liquid filling pipe 12 is fixedly equipped with a sealing cap; the heat dissipation fins 8 increase the heat dissipation area of the heat sink 701, thereby improving the heat dissipation efficiency of the cooling medium passing through the water supply pipe 607; the liquid filling pipe 12 facilitates the replenishment of the cooling medium in the coolant storage tank 601, wherein the bottom of the coolant storage tank 601 has a drain pipe, and the liquid filling pipe 12 improves the sealing effect of the coolant storage tank 601.
[0037] Working principle: The lower die holder 1 and upper die holder 2 are installed on the stamping machine. During the stamping process, the first water pump 602 is started. The first water pump 602 draws the cooling medium from the coolant storage tank 601 through the water pumping pipe 603, and disperses the cooling medium into two sets of water-filling telescopic hoses 605 through the first tee connector 604. This delivers the cooling medium to the cooling channels 3 in the lower die holder 1 and upper die holder 2 respectively. After flowing through the cooling channels 3, the cooling medium absorbs the heat from the lower die holder 1 and upper die holder 2, and then discharges it into the corresponding drain telescopic hoses 609 through the water outlet pipes 5. At the same time, the second water pump 606 is started to cool... The coolant returns to the coolant storage tank 601 through the water pipe 607. When the coolant passes through the middle of the water pipe 607, it is cooled by the heat dissipation mechanism 7. The cooling medium circulation mechanism 6 helps the lower mold base 1 and the upper mold base 2 to maintain a suitable temperature during operation, avoiding deformation and wear caused by high temperature. At the same time, the structure of this application is simple, reducing manufacturing costs. The fan 705 is driven by the heat dissipation box 701 to rotate, generating forced airflow, which carries away the heat in the heat dissipation box 701, realizing the heat dissipation of the cooling medium passing through the water pipe 607, effectively reducing the temperature of the cooling medium returning to the coolant storage tank 601.
[0038] The spiral cooling channel 3 extends the contact area between the cooling medium and the lower die holder 1 and the upper die holder 2, which helps the cooling medium to fully contact the surfaces of the lower die holder 1 and the upper die holder 2, improving the uniformity of cooling of the lower die holder 1 and the upper die holder 2. The temperature sensor 9 monitors the temperature of the lower die holder 1 and the upper die holder 2 in real time, which helps the staff to understand the temperature of the lower die holder 1 and the upper die holder 2 during the stamping process.
[0039] Meanwhile, the controller 10 receives the temperature data measured by the temperature sensor 9 and adjusts the speed of the motor 704 according to the temperature data measured by the temperature sensor 9. When the temperature is high, the speed of the motor 704 is increased, and when the temperature is low, the speed of the motor 704 is decreased, thereby controlling the heat dissipation effect of the cooling medium on the lower mold base 1 and the upper mold base 2, and improving the automation level of the device; the heat dissipation area of the heat dissipation box 701 is increased by the heat dissipation fins 8, which improves the heat dissipation efficiency of the cooling medium passing through the water pipe 607.
[0040] In addition, the liquid level observation window 11 allows staff to easily check the remaining amount of cooling medium in the coolant storage tank 601, improving its practicality during use; the filling pipe 12 facilitates the replenishment of cooling medium in the coolant storage tank 601, and the bottom of the coolant storage tank 601 has a drain pipe, while the filling pipe 12 improves the sealing effect of the coolant storage tank 601.
