Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to a stamping die for irregularly shaped forgings. Background Technology

[0002] In modern industrial systems, shaped forgings, with their unique shapes and superior performance, occupy an indispensable position in many key areas. In the aerospace field, shaped forgings are used to manufacture core components such as aircraft engine blades and fuselage frames, playing a decisive role in the safety and performance of aircraft. In the automotive manufacturing industry, they are widely used in car chassis, engine crankshafts, and other parts, greatly improving the handling and safety of vehicles. In the machining field, shaped forgings are an important component of various large-scale mechanical equipment, helping to achieve high-precision mechanical operation and driving various industries towards high-quality development.

[0003] A utility model patent with Chinese patent authorization announcement number "CN220698030U" discloses a stamping die for irregularly shaped forgings, including a worktable, an upper die base, a stamping rod, and a lower die base. The upper die base is movably installed above the worktable, and the stamping rod is movably installed in the middle of the upper die base. The lower die base is fixedly installed in the middle of the upper end of the worktable, and lower limit blocks are fixedly installed at the four corners of the upper end of the worktable. By setting a fixed plate and a screw, the output end of the stamping rod is moved downward to expose the fixed plate. The screw at the upper end of the fixed plate is removed to replace the stamping head. The stamping head is set separately below the fixed plate and is not integrated with the entire stamping die. It is not necessary to disassemble the entire stamping die to replace the stamping head, which makes it more convenient and faster to disassemble and replace the stamping head, reduces the waiting time of the stamping die, and ensures that the efficiency of the stamping die is not reduced when replacing the stamping head.

[0004] Regarding the aforementioned technologies, the inventors believe that in the above-mentioned utility model, the mold, by setting a fixed plate and a screw, makes the replacement of the stamping head more convenient, effectively reducing the waiting time caused by replacing the stamping head and improving stamping efficiency. However, the mold still has shortcomings in practical applications. Strong vibrations and impacts are generated during the stamping process, and the mold lacks effective buffering and shock absorption design, resulting in serious damage to mold components. Frequent mold replacements not only increase production costs but also affect production progress.

[0005] Therefore, it is necessary to provide a new stamping die for irregularly shaped forgings to solve the above-mentioned technical problems. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] This utility model provides a special-shaped forging stamping die, which includes: a worktable 1; a lower die base 11 is installed on the top of the worktable 1, and an upper die base 12 is provided above the lower die base 11. The four corners of the upper end of the worktable 1 are connected to the upper die base 12 through guide post limiting components; wherein, an installation frame 2 is provided on the outside of the upper die base 12, and buffer components are installed around the bottom of the installation frame 2; shock-absorbing components are installed at the four corners of the bottom of the installation frame 2, and the shock-absorbing components can reduce the vibration generated during the stamping process.

[0023] It should be noted that: the worktable 1 is the basic support structure of the entire stamping die, bearing the lower die holder 11 and other related components, providing a stable platform for stamping operations. The lower die holder 11 is installed on top of the worktable 1 to fix the lower die and is the basic component for placing the irregular forging to be stamped. During the stamping process, it bears the pressure from the upper die holder 12 and the reaction force of the forging. The upper die holder 12 is located above the lower die holder 11 and cooperates with the lower die holder 11 to complete the stamping forming of the irregular forging. It is connected to the worktable 1 through the guide post limiting assembly, and can move accurately up and down during the stamping process to ensure stamping accuracy. The guide post limiting assembly includes a lower limiting block, an upper limiting block, a limiting plate, guide posts, and connecting blocks. The lower die holder 11, the upper die holder 12, and the guide post limiting assembly are all prior art, and their internal structures and functions are disclosed in patent publication number CN220698030U, and will not be further described here. The buffer assembly is installed around the bottom of the mounting frame 2. During the stamping process, a significant impact force is generated when the punch contacts the workpiece and applies pressure. The buffer assembly absorbs and mitigates these impact forces, reducing damage to other parts of the die, extending the die's service life, and also reducing noise during stamping, thus improving the comfort of the working environment. Vibration damping components are installed at the four bottom corners of the mounting frame 2. Their function is to further reduce vibrations generated during stamping. The vibration damping components, used in conjunction with the buffer assembly, can more effectively improve the stability and reliability of the die, ensuring smooth stamping operations.

[0024] In an embodiment of this utility model, the buffer assembly includes two brackets 21 connected to the bottom of the mounting frame 2, and the two brackets 21 are arranged opposite to each other. A slide rod 22 is connected between the two brackets 21. Slider blocks 23 are slidably connected to both ends of the outer side of the slide rod 22. Buffer rods 24 are connected to the bottom of the two sliders 23. Buffer plates 25 are connected to the bottom of the two buffer rods 24. Buffer springs 26 are sleeved on the outer side of the slide rod 22 on the side of the two sliders 23 that are relatively far apart. Buffer pads 27 are installed at the bottom of the buffer plates 25. Buffer grooves are equidistantly opened at the bottom of the buffer pads 27. The tops of the two sliders 23 are slidably connected to the bottom of the mounting frame 2.

[0025] It should be noted that bracket 21 is connected to the bottom of mounting frame 2, and the two brackets 21 are arranged opposite each other, serving to support and fix slide rod 22. It provides a stable mounting position for slide rod 22, ensuring that slide rod 22 remains horizontal within the entire buffer assembly, allowing slider 23 to slide smoothly on slide rod 22 and ensuring the normal operation of the buffer assembly. Slide rod 22 is connected between the two brackets 21, serving as the sliding track for slider 23. Slider 23 can slide freely at both outer ends of slide rod 22, allowing the buffer assembly to move horizontally, thereby better absorbing and buffering the impact force generated during the stamping process. A buffer rod 24 is connected to the bottom of slider 23. When slider 23 slides, it drives buffer rod 24 and buffer plate 25 to move together, thereby transmitting the impact force to buffer spring 26 to achieve the purpose of buffering. Simultaneously, the tops of both sliders 23 are slidably connected to the bottom of mounting frame 2, further ensuring the stability and accuracy of slider 23 during sliding. The buffer spring 26, sleeved on the outside of the slide bar 22 on the side of the two sliders 23 that are relatively far apart, is one of the core components of the buffer assembly. When subjected to a stamping impact, the sliders 23 slide to both sides, compressing the buffer spring 26. The buffer spring 26 absorbs the energy of the impact force through its own elastic deformation, converting kinetic energy into elastic potential energy, thereby mitigating the impact force on the mold. When the impact force disappears, the buffer spring 26 returns to its original shape, pushing the sliders 23 back to their original position. The buffer pad 27 further absorbs and buffers the impact force, reducing damage to the mold and workpiece. The design of the buffer groove increases the elastic deformation capacity of the buffer pad 27, enabling it to better absorb the impact force, while also improving the wear resistance and service life of the buffer pad 27.

[0026] In an embodiment of this utility model, the shock absorption assembly includes dampers 3 connected to the bottom perimeter of the mounting frame 2, and the bottom of each damper 3 is connected to the top of the workbench 1.

[0027] It should be noted that: Dampers 3 are connected to the bottom of the mounting frame 2 on all four sides, and the bottom of each damper 3 is connected to the top of the worktable 1. The damper 3 is the core component of the vibration damping assembly. Its main function is to dissipate vibration energy through the flow of internal damping media (such as oil). During the stamping process, the mounting frame 2 vibrates due to the stamping action, and this vibration is transmitted to the worktable 1 through the dampers 3. The damping media inside the dampers 3 resists the transmission of vibration, causing the vibration to gradually attenuate during transmission. When the mounting frame 2 vibrates up and down, the piston inside the damper 3 reciprocates in the damping media. The viscosity of the damping media hinders the movement of the piston, thereby converting the kinetic energy of the vibration into heat energy and other forms of energy to dissipate, achieving the effect of vibration damping. The worktable 1, as the lower connecting component of the dampers 3, provides a stable support foundation for the dampers 3. It bears the attenuated vibration transmitted through the dampers 3 and also provides a stable working platform for the entire mold. During the vibration damping process, the worktable 1 plays a crucial role in absorbing and dispersing vibration energy, enabling the mold to remain relatively stable during operation and reducing the impact of vibration on the surrounding environment and equipment. The damper 3 is an existing and mature technology and will not be described further here.

[0028] The working principle of the irregular forging stamping die provided by this utility model is as follows: When the stamping equipment is started, the upper die holder 12 moves downward along the guide post limiting assembly under the drive of the stamping equipment, approaching the irregular forging blank placed on the lower die holder 11. At the moment when the upper die holder 12 moves downward and contacts the blank, a strong impact force and vibration will be generated. These impact forces and vibrations are first transmitted to the mounting frame 2. The buffer assembly around the bottom of the mounting frame 2 begins to function. The buffer pad 27 first contacts the vibration and transmits it to the buffer plate 25. The buffer plate 25 drives the buffer rod 24, causing the slider 23 to slide to both sides on the slide rod 22, thereby compressing the buffer spring 26. The buffer spring 26 absorbs part of the impact force through elastic deformation, converting kinetic energy into elastic potential energy. At the same time, the vibration of the mounting frame 2 is also transmitted to the worktable 1 through the damper 3. The piston inside the damper 3 reciprocates in the damping medium. The viscosity of the damping medium hinders the piston movement, converting the kinetic energy of the vibration into heat energy and other forms of energy to dissipate, thus attenuating the vibration. After stamping is completed, the upper die holder 12 moves upward under the action of the stamping equipment. At this time, the buffer spring 26 returns to its original state, pushing the slider 23 back to its initial position, preparing for the next stamping. Throughout the process, the guide post limiting assembly ensures the precise fit between the upper die holder 12 and the lower die holder 11, while the buffer assembly and shock absorption assembly effectively reduce the impact of vibration and impact on the mold and the surrounding environment, ensuring the stable and efficient operation of the stamping process.

[0029] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
