Description

Technical Field

[0001] This utility model relates to the field of punching device technology, specifically a direct punching device for forging products. Background Technology

[0002] In modern industrial production, forged products, with their excellent properties such as high strength and high toughness, are widely used in aerospace, automobile manufacturing, and machinery equipment. Punching, as a key process in forging, refers to the machining of holes in forged products using specific equipment to meet design requirements, satisfying functional needs such as structural connections and fluid transport. With the continuous expansion of industrial production scale and the increasing demands for product precision, higher standards are being placed on the accuracy, efficiency, and automation of punching in forging products. Highly efficient and precise punching equipment has become a core element in ensuring the quality and production efficiency of forged products.

[0003] Traditional punching technology for forging products has many drawbacks. Firstly, traditional equipment often employs mechanical stamping, which is complex in structure and cumbersome in operation. This requires significant manpower for equipment debugging and operation, and precise positioning during punching is difficult, leading to large hole position deviations and low product yield. Secondly, the high temperatures generated during punching due to friction can easily alter material properties, affecting product quality. Furthermore, the large amount of debris produced, if not cleaned promptly, will accumulate in the working area, interfering with normal punching operations, reducing production efficiency, and increasing equipment maintenance costs. This makes it difficult to meet the high-efficiency, high-quality production demands of modern industry. Therefore, we propose a direct punching device for forging products. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a direct punching device for forging products, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a direct punching device for forging products, including a worktable, a mold base fixedly connected to the top of the worktable, a punching bottom mold provided at the bottom of the inner wall of the mold base, the top of the punching bottom mold extending to the top of the mold base, a stamping groove opened at the bottom of the inner wall of the punching bottom mold, a limit groove opened at the top of the punching bottom mold, a support frame fixedly connected to the top of the worktable near the mold base, a hydraulic rod fixedly connected to the top of the support frame, and the bottom output end of the hydraulic rod extending to the top of the inner wall of the support frame.

[0006] Preferably, the limiting groove is connected to the output end of the stamping groove, and the diameter of the limiting groove is larger than the diameter of the stamping groove.

[0007] Preferably, a punch rod is fixedly connected to the bottom output end of the support frame, the bottom of the punch rod is provided with a limiting head, and the bottom of the limiting head is provided with a stamping head.

[0008] Preferably, the outer wall of the limiting head is fitted into the inner wall of the limiting groove.

[0009] Preferably, the bottom output end of the stamping head is fitted into the inner wall of the stamping groove.

[0010] Preferably, a fan is fixedly connected to one end of the outer wall of the workbench, a connecting seat is fixedly connected to the outer wall of the workbench near the fan, and the output end of the fan is fixedly connected to the outer wall of one side of the connecting seat.

[0011] Preferably, a fixed frame is fixedly connected to one end of the top of the workbench, a cooling head is provided on the top of the fixed frame, the top connecting end of the connecting seat is fixedly connected to the outer wall of one end of the cooling head, and the output end of the cooling head faces the top of the punching bottom die.

[0012] Compared with the prior art, this utility model provides a direct punching device for forging products, which has the following beneficial effects:

[0013] 1. This direct punching device for forging products, compared to traditional punching equipment which often suffers from large hole position deviations and low product yield due to its complex mechanical stamping structure and difficult positioning, offers a significant advantage. This device utilizes a precise fitting design between a limiting groove and a limiting head to provide accurate guidance for the punching head. During punching, the limiting head engages with the limiting groove, restricting the lateral movement of the punching head and ensuring precise punching along the vertical direction. This guarantees accurate alignment between the punching head and the stamping groove, effectively preventing misalignment. Compared to traditional technologies, this precise positioning mechanism significantly improves punching accuracy, keeping the hole position error of forged products within a minimal range, significantly increasing the product yield, and meeting the modern industrial demand for high-precision components.

[0014] 2. This direct punching device for forging products, compared to traditional punching devices which lack effective chip removal and cooling mechanisms, leading to chip accumulation that interferes with operation and high temperatures that affect production continuity and result in low efficiency, addresses these issues. In this device, a fan at one end of the worktable directs airflow to the punching area via a connecting seat. With the assistance of the connecting seat, a cooling head sprays airflow onto the forging product, reducing the high temperatures generated during punching and preventing overheating-induced processing halts. Furthermore, the hydraulic drive system is simpler to operate than traditional mechanical punching, reducing equipment setup time. These design features enable continuous and stable operation, effectively reducing downtime for cleaning and cooling, significantly improving production efficiency, shortening production cycles, and meeting the high-efficiency demands of modern large-scale industrial production.

[0015] 3. This direct punching device for forging products addresses the significant impacts on product quality caused by high-temperature-induced material property changes and debris interference, which are crucial factors in traditional techniques. Through the cooling function of the cooling head, this device effectively reduces the temperature of the forged product during the punching process, preventing changes in material properties due to high temperatures and ensuring that key performance indicators such as strength and toughness remain unaffected. Precise positioning and punching mechanisms guarantee that the shape and size of the holes meet design requirements, further improving product quality. Compared to traditional techniques, this device addresses multiple aspects to comprehensively ensure the quality of forged products, enhancing their competitiveness in the market.

[0044] Working Principle: First, the hydraulic rod 7, in conjunction with the punch rod 8, drives the limiting head 9 and the punching head 10. The hydraulic rod 7 is fixed to the top of the support frame 6, with its bottom output end extending to the top of the inner wall of the support frame 6, and the bottom is fixedly connected to the punch rod 8. When punching is required, the hydraulic rod 7 is activated, its output end extends, and drives the connected punch rod 8 downward. The bottom of the punch rod 8 is connected to the limiting head 9 and the punching head 10. The movement of the punch rod 8 drives the limiting head 9 and the punching head 10 downward together, thus providing power for punching. The limiting head 9 is linked to the limiting groove 5, achieving the positioning and guiding effect of the punching head 10. The limiting groove 5 is opened at the top of the punching bottom die 3 and is connected to the punching groove 4. Its diameter is larger than that of the punching groove 4. The outer wall of the limiting head 9 fits into the inner wall of the limiting groove 5. When the limiting head 9 moves downward with the punch rod 8, the limiting head 9 is embedded in the limiting groove 5. Due to the engagement between the limiting head 9 and the limiting groove 5, the positional accuracy of the punching head 10 during downward movement is ensured, allowing it to accurately align with the punching groove 4 and improving punching precision. The punching head 10 is linked to the punching groove 4 to achieve the punching effect on the forged product. The punching groove 4 is located at the bottom of the inner wall of the punching die 3, and the bottom output end of the punching head 10 engages with the inner wall of the punching head 10. After the limiting head 9 is inserted into the limiting groove 5, the punching head 10 continues to move downward, and the bottom of the punching head 10 contacts the forged product placed on the punching die 3, gradually pressing the product into the punching groove 4, thus completing the punching operation. The blower 11, linked to the connecting seat 12, achieves a blowing effect on the area of ​​the punching die 3. The blower 11 is fixed to the outer wall of one end of the worktable 1, and its output end is fixedly connected to the outer wall of one side of the connecting seat 12. After the fan 11 is started, it blows air toward the connecting seat 12. The connecting seat 12 guides the airflow. The cooling head 14 is linked to the connecting seat 12 to achieve the cooling effect on the forging product. The output end of the cooling head 14 faces the top of the punching bottom die 3 so that the blown air can be blown more accurately toward the area where the punching bottom die 3 is located, which helps to clean up the debris generated during the punching process and keep the working area clean.
