Description

Technical Field

[0001] This utility model relates to the field of forging dies, and more specifically, to a forging device for irregularly shaped forgings. Background Technology

[0002] In today's booming manufacturing industry, irregularly shaped forgings, as metal parts with complex geometries or asymmetrical structures, occupy a crucial position in many key fields. In the automotive industry, irregularly shaped forgings such as gears and differential housings are widely used, and their high strength and fatigue resistance effectively ensure the stable operation of vehicles. The aerospace industry has even more stringent requirements for irregularly shaped forgings, such as turbine blades and engine mounts, which need to maintain excellent performance in extreme environments to provide solid support for the safe flight of aircraft. In the machinery manufacturing industry, irregularly shaped forgings are also often used in components that bear high loads to ensure the efficient and reliable operation of mechanical equipment.

[0003] However, existing forging processes face two major bottlenecks: First, after the forging die completes the forming of the forging, the cooling cycle typically lasts for several minutes or even tens of minutes due to residual heat in the metal and the limited thermal conductivity of the die, severely restricting production line cycle time. Second, the surface temperature of the forging remains in the high-temperature range of 200-500℃ after demolding. Manual removal of the parts not only poses a risk of burns, but the frequent waiting for cooling further exacerbates efficiency losses. These pain points not only limit the production scale of irregularly shaped forgings, but also pose challenges to die life and equipment stability—prolonged high-temperature retention can easily lead to die thermal fatigue, causing crack initiation, while uneven temperature distribution exacerbates equipment load fluctuations and increases maintenance costs.

[0004] Based on this, the present invention designs a forging device for irregularly shaped forgings to solve the above problems. Utility Model Content

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1) In this invention, after the upper and lower molds complete the mold closing operation, two sets of circulating pumps are immediately started. The circulating pumps transport the cooling water in the water tank to the spiral heat dissipation channels of the upper and lower molds through the inlet pipes, using the channels to efficiently dissipate heat from the molds. The cooled water flows out of the channels, enters the circulating pump through the extraction hose and the extraction pipe, and then returns to the water tank through the return pipe. The cooler in the water tank will cool the warm water, thus forming a circulating water cooling system to ensure that the mold is always at a suitable working temperature.

[0020] 2) In this utility model, when the upper mold moves downward, it drives the four guide rods to move synchronously, thereby pushing the four limit plates downward. During this process, the limit plates drive the buffer springs to extend, and the elastic reaction force generated by the buffer springs can effectively buffer the downward pressure, which can not only reduce the wear of the mold caused by impact, but also improve the service life and working stability of the mold.

[0021] 3) In summary, this utility model, through the dual technology design of circulating water cooling and buffer spring, achieves precise control of mold temperature on the one hand, avoiding quality problems of forgings caused by high temperature; on the other hand, it enhances the impact resistance of the mold, ensures the stable operation of the forging process, and effectively improves forging efficiency and product quality, thus having significant practical value and innovation.

[0028] Example: Please refer to Figure 1-5 A forging device for irregularly shaped forgings includes a workbench 1, with columns 2 fixedly connected to the four corners of the top of the workbench 1. The tops of the columns 2 are all fixedly connected to the bottom of the top plate 3. A buffer assembly is provided inside the top plate 3, and a cooling assembly is provided on the top of the workbench 1.

[0029] The buffer assembly includes guide rods 20, the outer sides of which are slidably connected to the inside of the top plate 3. Limiting plates 21 are fixedly connected to the outer sides of the guide rods 20. Buffer springs 22 are fixedly connected to the top of the limiting plates 21. The end of the buffer springs 22 away from the limiting plates 21 is fixedly connected to the bottom of the top plate 3.

[0030] The workbench 1 is fixedly connected to the top plate 3 via the column 2. The top plate 3 is used to install the hydraulic cylinder 4, the guide rod 20 and the buffer spring 22. The hydraulic cylinder 4 is used to drive the upper mold 5 to perform the mold closing operation. The limit plate 21 cooperates with the buffer spring 22. The elastic reaction force generated by the buffer spring 22 can effectively buffer the impact force generated by the mold closing.

[0031] Reference Figure 1-3 The cooling assembly includes a circulating pump 7 and a circulating pump 15. The bottoms of both circulating pumps 7 and 15 are fixedly connected to the top of the workbench 1. A suction hose 8 is fixedly connected to the output end of circulating pump 7, and a spiral cooling channel 9 is fixedly connected to the other end of the suction hose 8. The spiral cooling channel 9 is located inside the upper mold 5, and a water inlet pipe 10 is fixedly connected to the other end of the spiral cooling channel 9. The other end of the water inlet pipe 10 is fixedly connected to the inside of the water tank 12. A return pipe 11 is fixedly connected to the input end of circulating pump 7. The other end of pipe 11 is fixedly connected to the inside of water tank 12. The output end of circulation pump 15 is fixedly connected to water suction pipe 16. The other end of water suction pipe 16 is fixedly connected to the inside of spiral heat dissipation channel 17. Spiral heat dissipation channel 17 is set inside the lower mold 6. The other end of spiral heat dissipation channel 17 is fixedly connected to water inlet pipe 18. The other end of water inlet pipe 18 is fixedly connected to the inside of water tank 12. The input end of circulation pump 15 is fixedly connected to return pipe 19. The other end of return pipe 19 is fixedly connected to the inside of water tank 12.

[0032] During operation, two sets of circulating pumps operate synchronously, pumping the cooling water in water tank 12 to the spiral heat dissipation channels of the upper and lower dies. The cooling water in the spiral heat dissipation channels fully absorbs the heat generated by the dies during forging, achieving efficient heat dissipation. The cooled water then flows back to water tank 12 through return pipe 11 and return pipe 19, working in conjunction with the cooling effect of the chiller 14 inside the water tank to form a closed-loop circulating water cooling system. This ensures that the upper and lower dies maintain a suitable working temperature throughout the continuous forging operation, effectively improving forging quality and die lifespan.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The bottom of the water tank 12 is fixedly connected to the top of the workbench 1. The top of the water tank 12 is provided with a water inlet 13. The bottom of the lower mold 6 is fixedly connected to the top of the workbench 1. The top of the upper mold 5 is fixedly connected to the output end of the hydraulic cylinder 4. The hydraulic cylinder 4 is fixedly connected to the top of the top plate 3. The bottom end of the guide rod 20 is fixedly connected to the four corners of the top of the upper mold 5. The cooler 14 is fixedly connected inside the water tank 12.

[0034] The bottom of the water tank 12 is firmly fixed to the top of the workbench 1, and its top is equipped with a water inlet 13, allowing operators to easily add cooling water and ensuring that the water tank 12 always has a sufficient amount of cooling water. The lower mold 6 is also fixed to the top of the workbench 1, providing a stable foundation support for the forging. The top of the upper mold 5 is tightly connected to the output end of the hydraulic cylinder 4, which is fixedly installed on the top plate 3. This design allows the hydraulic cylinder 4 to precisely drive the upper mold 5 to move up and down, realizing the opening and closing operation with the lower mold 6. The bottom end of the guide rod 20 is fixed to the four corners of the top of the upper mold 5. With its precise guiding function, it ensures that the upper mold 5 remains stable during movement, avoids deviation, and ensures the accuracy of the forging process. In addition, the water tank 12 has a built-in cooler 14. When the cooled water flows back to the water tank 12, the cooler 14 is quickly activated to rapidly cool the water, allowing the cooling water to be recycled and continuously providing heat dissipation for the mold, maintaining the efficient and stable operation of the entire forging device.

[0035] Working principle of this utility model:

[0036] First, the forging material is precisely poured into the lower mold 6 fixed to the worktable 1. Then, the hydraulic cylinder 4 on the top of the top plate 3 is activated. The hydraulic cylinder 4 drives the upper mold 5 to move smoothly downward through its output end until the upper mold 5 and the lower mold 6 are tightly fitted together. During this process, the forging material is gradually compressed and shaped within the lower mold 6. As the upper mold 5 moves downward, the four guide rods 20 fixed at its top four corners move synchronously, thereby driving the limiting plate 21 fixed on the guide rods 20 to move downward. During the downward movement, the limiting plate 21 stretches the buffer spring 22, and the elastic reaction force generated by the buffer spring 22 can effectively offset the impact force generated when the upper mold 5 is pressed down. This not only significantly reduces the wear of the mold caused by impact but also significantly improves the service life and working stability of the mold, ensuring the smooth progress of the forging process.

[0037] Once the upper and lower molds are closed, two sets of circulating pumps immediately start, initiating the mold cooling process. The circulating pumps deliver cooling water from the water tank 12 to the spiral cooling channels inside the upper and lower molds via inlet pipes. The cooling water in the spiral cooling channels fully absorbs the heat generated by the mold during forging, achieving efficient heat dissipation. After cooling, the warm water is drawn back to the circulating pump through the extraction hose 8 and extraction pipe 16, and then reinjected into the water tank 12 via the return pipe. At this time, the cooler 14 inside the water tank 12 quickly cools the returning warm water, restoring it to a suitable cooling temperature. This cycle repeats continuously, forming a highly efficient and stable circulating water cooling system, ensuring that the mold is always within the ideal working temperature range and preventing overheating from affecting the quality of the forgings and the mold performance.
