Description

Technical Field

[0001] This utility model relates to the field of forging equipment, and in particular to a gear blank forging equipment. Background Technology

[0002] Gear blank forging is a crucial initial step in gear manufacturing. It refers to the process of applying pressure to a metal blank to induce plastic deformation, thereby obtaining a gear blank with specific shape, size, and mechanical properties. This process improves the metal's microstructure and properties. The process includes raw material preparation, heating, forging, heat treatment, and subsequent processing. The gear blank forging equipment, as a key component, mainly consists of a forging press and dies. The forging press provides the pressure, while the dies determine the shape and size of the blank.

[0003] Traditional gear blank forging equipment has significant technical drawbacks: during the forging of heat-treated blanks, the blanks transfer a large amount of heat to the die. Due to the limited heat dissipation capacity of the die, the die temperature continues to rise. This reduces the hardness and strength of the die material, shortens its service life, and causes thermal deformation of the die, affecting the dimensional and shape accuracy of the gear blank. It may even lead to defects such as blank sticking during forging, reducing product quality and production efficiency. Therefore, this application proposes a gear blank forging equipment to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a gear blank forging equipment that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A gear blank forging equipment includes a forging press, a worktable fixedly mounted on the forging press, a forging die fixedly mounted on the upper end of the worktable, an annular cooling groove through which the forging die passes vertically, two cooling components symmetrically fixedly mounted vertically within the annular cooling groove, each cooling component consisting of an annular cooling water pipe and a connecting water pipe, the connecting water pipe being fixedly inserted into one side wall of the annular cooling water pipe, and a plurality of cooling fins fixedly mounted within the annular cooling groove and between the two cooling components.

[0007] Preferably, the forging press is equipped with a forging punch, and a forging die is fixedly installed at the lower end of the forging punch.

[0008] Preferably, two mounting slots are symmetrically formed on the outer wall of the forging lower die, and the mounting slots are connected to the annular cooling channel.

[0009] Preferably, two mounting connecting plates are symmetrically fixedly installed on the lower outer wall of the forging die.

[0010] Preferably, the annular cooling water pipe on the cooling assembly is fixedly embedded in the annular cooling channel, and a plurality of water flow perforations are opened on the inner wall of the annular cooling water pipe. The connecting water pipe passes through the installation channel and is connected to the cooling water circulation equipment.

[0011] Preferably, the cooling fins are fixedly connected to the inner wall of the annular cooling channel, and the cooling fins are also fixedly connected to the annular cooling water pipe on the cooling assembly.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By creating an annular cooling channel on the lower forging die, and installing a cooling assembly consisting of an annular cooling water pipe and connecting water pipes within the annular cooling channel, while placing cooling fins between the two cooling assemblies, cooling water can flow into the annular cooling water pipes through the connecting water pipes during equipment operation. This water then flows evenly into the annular cooling channel through water flow perforations. Combined with the increased heat dissipation area from the cooling fins, the heat generated by the forging of the blank in the lower forging die is quickly dissipated, effectively controlling the temperature of the lower forging die. This avoids problems such as decreased material hardness and strength, and shortened service life caused by excessively high die temperatures. Simultaneously, it reduces the impact of thermal deformation of the lower forging die on the size and shape accuracy of the gear blank, lowers the probability of defects such as blank sticking during forging, and ultimately improves product quality and production efficiency.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5 As shown, a gear blank forging equipment includes a forging press 1, a worktable 2 fixedly mounted on the forging press 1, a forging die 3 fixedly mounted on the upper end of the worktable 2, an annular cooling groove 8 formed on the forging die 3, the annular cooling groove 8 penetrating the forging die 3 vertically, two cooling components 4 symmetrically fixedly mounted vertically within the annular cooling groove 8, the cooling components 4 consisting of an annular cooling water pipe 11 and a connecting water pipe 12, the connecting water pipe 12 being fixedly inserted into one side wall of the annular cooling water pipe 11, and a plurality of cooling fins 5 fixedly mounted within the annular cooling groove 8 and between the two cooling components 4. By forming an annular cooling groove 8 on the forging die 3 and setting annular cooling fins 5 within the annular cooling groove 8, the equipment achieves the desired cooling effect. The cooling assembly 4, consisting of the cooling pipe 11 and the connecting pipe 12, has cooling fins 5 between the two cooling assemblies 4. When the equipment is running, cooling water can flow into the annular cooling water pipe 11 through the connecting pipe 12 and then flow evenly into the annular cooling channel 8 through the water flow perforation 13. The cooling fins 5 increase the heat dissipation area and quickly remove the heat generated by the forging die 3 during the forging of the blank. This effectively controls the temperature of the forging die 3 and avoids problems such as reduced material hardness and strength and shortened service life caused by excessive temperature of the forging die 3. At the same time, it reduces the impact of thermal deformation of the forging die 3 on the size and shape accuracy of the gear blank and reduces the probability of defects such as sticking to the die during blank forging, thereby improving product quality and production efficiency.

[0022] Specifically, a forging punch 6 is installed on the forging press 1. A forging upper die 7 is fixedly installed at the lower end of the forging punch 6. Two mounting slots 9 are symmetrically opened on the outer wall of the forging lower die 3. The mounting slots 9 are interconnected with the annular cooling channel 8. Two mounting connecting plates 10 are symmetrically fixedly installed on the lower outer wall of the forging lower die 3. An annular cooling water pipe 11 on the cooling assembly 4 is fixedly embedded in the annular cooling channel 8. Several water flow perforations 13 are opened on the inner wall of the annular cooling water pipe 11. A connecting water pipe 12 passes through the mounting slot 9 and is connected to the cooling water circulation equipment. The cooling fins 5 are fixedly connected to the inner wall of the annular cooling channel 8. The cooling fins 5 are simultaneously connected to the inner wall of the annular cooling channel 8. The annular cooling water pipe 11 on the cooling assembly 4 is fixedly connected. The upper end of the upper cooling assembly 4 is lower than the upper end of the forging lower die 3. This design can effectively prevent the cooling assembly 4 from being hit by the forging upper die 7 during the forging process, thereby ensuring the structural integrity and normal working performance of the cooling assembly 4. The material selection of the cooling fins 5 must have good thermal conductivity, such as copper or aluminum alloy, to ensure efficient heat transfer and improve heat dissipation. The annular cooling channel 8 is sealed by the two cooling assemblies 4. Specifically, sealing structures such as sealing gaskets can be set at the contact parts of the cooling assembly 4 and the annular cooling channel 8 and the mounting slot 9 to effectively prevent cooling water leakage and ensure the normal operation of the equipment.

[0023] When forging gear blanks, the heat-treated blank is placed into the cavity of the lower forging die 3, and then the forging press 1 is started. At this time, the forging punch 6 drives the upper forging die 7 to move downward. Finally, the forging punch 6 provides the punching force, and with the cooperation of the upper forging die 7 and the lower forging die 3, the blank is forged into shape. During the forging process, the heat on the blank is transferred to the lower forging die 3. Therefore, the cooling water circulation equipment connected to the cooling assembly 4 is started at the same time during the forging process. At this time, the cooling water circulation equipment delivers cooling water to the upper cooling assembly 4 to cool the blank. Water enters the annular cooling water pipe 11 on the upper cooling component 4 through the connecting water pipe 12 on the upper cooling component 4. Then, the cooling water flows into the annular cooling channel 8 through the water flow perforation 13 on the inner wall of the annular cooling water pipe 11 on the upper cooling component 4. At the same time, the cooling fins 5 increase the heat dissipation area and quickly remove the heat generated by the forging die 3 during forging, thereby cooling the forging die 3, controlling its temperature, and avoiding excessive temperature from affecting the performance of the die and the quality of the blank. Then, the cooling water that has completed the cooling of the forging die 3 will flow back to the cooling water circulation equipment through the lower cooling component 4.

[0024] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
