Description

Technical Field

[0001] This utility model relates to the field of stamping device technology, specifically to a stamping device for power fittings. Background Technology

[0002] Power fittings are metal accessories used in power transmission and distribution systems to connect, fix, or support various power equipment, primarily responsible for transmitting mechanical and electrical loads. They are generally made of iron, aluminum, or aluminum alloy and are used to connect equipment via bolts, crimping, or welding. During manufacturing, processes such as punching, cutting, and bending require corresponding stamping equipment. The main difference between various types of stamping equipment lies in the molds used. Because the punching, cutting, and bending processes of power fittings are all cold stamping, the molds of the corresponding stamping equipment do not have cooling mechanisms. The heat generated during the stamping process relies on natural cooling, which can lead to the module's temperature remaining high due to excessively high ambient temperatures, thus affecting the mold's lifespan. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a stamping device for power fittings.

[0004] To achieve the above objectives, this utility model provides a stamping device for power fittings, including a base frame. An upper base plate and a lower base plate are respectively provided at the upper and lower ends of the base frame. A hydraulic unit is provided on the lower base plate. A frame is provided on the upper side of the upper base plate. A stamping cylinder is fixed on the frame and connected to the hydraulic unit. An upper die assembly is provided between the lower end of the stamping cylinder and the frame. A lower die assembly is fixed on the upper base plate and is located below the upper die assembly. An air duct is inserted through the upper base plate. An air inlet is provided at one end of the air duct and is located on one side of the upper and lower die assemblies. A fan is provided at the other end of the air duct.

[0005] Furthermore, the hydraulic unit includes a hydraulic oil tank and a hydraulic oil pump connected between the hydraulic oil tank and the stamping cylinder. The hydraulic oil tank is also connected to a cooling oil pump, which is connected to a heat exchanger. The fan is located at one end of the heat exchanger, and the other end of the air duct is connected to the other end of the heat exchanger.

[0006] Furthermore, an air filter is provided on the outside of the air inlet.

[0007] Furthermore, the upper mold assembly includes a slide fixed on the frame and a slide sleeve fixed on the lower side of the stamping cylinder. The slide sleeve is slidably connected to the inner side of the slide, and an upper mold base is fixed to the lower end of the slide sleeve. An upper mold is fixed to the lower end of the upper mold base.

[0008] Furthermore, the lower mold assembly includes a lower mold base fixed to the upper side of the upper base plate, and a lower mold is fixed to the upper side of the lower mold base, with the upper mold and the lower mold corresponding in position.

[0009] Furthermore, the underside of the base frame is provided with multiple support legs.

[0010] Beneficial effects: This utility model sets up an air duct inside the device, with the air inlet of the air duct located near the upper and lower dies. The air outlet of the air duct is connected to one end of the heat exchanger, and the other end of the heat exchanger is connected to a fan. When the fan is working, it can draw air from the vicinity of the upper and lower dies, thereby promoting airflow near the upper and lower dies. This facilitates the removal of heat generated by the upper and lower dies during the stamping operation, preventing the upper and lower dies from overheating and affecting their lifespan. The air in the air duct enters the heat exchanger, which can continue to dissipate heat from the hydraulic oil flowing through the heat exchanger, thus meeting the heat dissipation requirements of the hydraulic oil.

[0013] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0014] like Figure 1 and Figure 2 As shown, this embodiment of the utility model provides a stamping device for power fittings, including a base frame 1, with an upper base plate 2 and a lower base plate 3 fixedly connected to the upper and lower ends of the base frame 1, respectively. A hydraulic unit is provided on the lower base plate 3. A frame 4 is fixedly connected to the upper side of the upper base plate 2, and the frame 4 is offset L-shaped. A stamping cylinder 5 is fixed on the frame 4, and the stamping cylinder 5 is connected to the hydraulic unit, which provides hydraulic power to the stamping cylinder 5 to control its operation. An upper die assembly 6 is provided between the lower end of the stamping cylinder 5 and the frame 4. A lower die assembly 7 is fixed on the upper base plate 2, and the lower die assembly 7 is located below the upper die assembly 6. When the stamping cylinder 5 is extended, a stamping operation is performed. An air duct 8 is inserted through the upper base plate 2, with an air inlet at one end of the air duct 8 located on one side of the upper die assembly 6 and the lower die assembly 7, and a fan 9 at the other end of the air duct 8. When the fan 9 is running, the air near the upper mold assembly 6 and the lower mold assembly 7 can be drawn into the air duct 8, thereby increasing the airflow speed near the upper mold assembly 6 and the lower mold assembly 7 and improving the heat dissipation effect.

[0015] The hydraulic unit of this embodiment includes a hydraulic oil tank 10 and a hydraulic oil pump 11 connected between the hydraulic oil tank 10 and the stamping cylinder 5. The hydraulic oil tank 10 is also connected to a cooling oil pump 12, which is connected to a heat exchanger 13. A fan 9 is located at one end of the heat exchanger 13, and the other end of the air duct 8 is connected to the other end of the heat exchanger 13. The heat exchanger 13 is a gas-liquid heat exchanger. The cooling oil pump 12 can draw hydraulic oil from the hydraulic oil tank 10 into the heat exchanger 13, and then return it to the hydraulic oil tank 10 through the return oil pipe 14 connected to the heat exchanger 13. When the fan 9 is running, air is drawn from the vicinity of the upper mold assembly 6 and the lower mold assembly 7 using the air duct 8. As the air flows through the heat exchanger 13, it dissipates heat from the hydraulic oil in the heat exchanger 13, thus meeting the cooling requirements of the hydraulic oil. To prevent dust and other impurities in the air from entering the air duct 8, it is preferable to install an air filter 15 on the outside of the air inlet. The air filter 15 can be a non-woven fabric air filter, which can be fixed to the air inlet by an air inlet grille or a metal mesh, making it easy to disassemble and replace.

[0016] The upper die assembly 6 of this embodiment includes a slide block 61 fixed on the frame 4, a sliding sleeve 62 fixed at the lower end of the telescopic shaft of the stamping cylinder 5, the sliding sleeve 62 being slidably connected to the inner side of the slide block 61, an upper die base 63 fixed at the lower end of the sliding sleeve 62, and an upper die 64 fixed at the lower end of the upper die base 63. Under the action of the slide block 61 and the sliding sleeve 62, the upper die 64 can move stably up and down when the stamping cylinder 5 is extended and retracted. The lower die assembly 7 of this embodiment includes a lower die base 71 fixed on the upper side of the upper base plate 2, a lower die 72 fixed on the upper side of the lower die base 71, and the upper die 64 and the lower die 72 being positioned correspondingly.

[0017] Multiple support legs 16 are provided on the lower side of the base frame 1. The support legs 16 can be threaded to the lower end of the base frame 1. Locking nuts 17 are also threaded to the outside of the support legs 16. After adjusting the height and level of the base frame 1, the support legs 16 can be locked and fixed to the base frame 1 by locking nuts 17.

[0018] The above description is merely a preferred embodiment of this utility model. It should be noted that for those skilled in the art, other parts not specifically described are existing technology or common knowledge.
