Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a forging die for processing automotive parts. Background Technology

[0002] In the automotive parts manufacturing industry, forging is a key process for achieving high-precision machining of metal parts, and the performance of forging dies directly affects the quality of parts, production efficiency, and the service life of the dies themselves. Traditional automotive parts forging dies typically use a rigid connection between the upper and lower die components during the forging process. When the high-speed moving upper die applies pressure to the blank, the huge impact force acts directly on the die body. The lack of an elastic buffer structure that can effectively absorb vibration energy leads to fatigue wear of various die components due to high-frequency impact, and even cracking or deformation.

[0003] Based on the above, this utility model proposes a forging die for processing automotive parts, which can effectively solve the above problems. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing a forging die for processing automotive parts.

[0020] A forging die for processing automotive parts, comprising

[0021] The upper mold assembly includes an upper mold base 1, an upper template 2 fixedly connected to the bottom of the upper mold base 1, and an upper forging block 3 fixedly connected to the bottom of the upper template 2.

[0022] The lower die assembly includes a lower die base 4, a buffer plate 5 is provided above the lower die base 4, a through hole 51 is provided in the middle of the buffer plate 5, a lower forging block 6 adapted to the upper forging block 3 is installed in the through hole 51, and the lower forging block 6 is fixedly connected to the lower die base 4; a plurality of buffer springs 7 are connected between the bottom perimeter of the buffer plate 5 and the lower die base 4; guide holes 52 are provided at the four corners of the buffer plate 5, the guide holes 52 are slidably connected to the first guide rod 8, and the bottom of the first guide rod 8 is fixedly connected to the lower die base 4.

[0023] This invention absorbs the forging impact force through the buffer spring 7 at the bottom of the buffer plate 5, transforming rigid collisions into elastic buffers, extending the service life of the forging die, and reducing maintenance frequency and costs. At the same time, after forging is completed, the rebound force of the buffer spring 7 causes the buffer plate 5 to automatically reset, simplifying the part removal process, reducing manual intervention, shortening the single batch processing cycle, and improving production efficiency.

[0024] Furthermore, in another embodiment, positioning blocks 9 are fixedly connected to the top perimeter of the buffer plate 5.

[0025] By setting multiple positioning blocks 9, the blanks of automotive parts to be forged can be positioned to ensure that the blanks are accurately positioned during the forging process.

[0026] Furthermore, in another embodiment, the lower mold base 4 is fixedly connected to two sides with buffer limit blocks 10 in the shape of the number "7", and the buffer plate 5 is provided with limit grooves 53 on both sides that cooperate with and connect with the buffer limit blocks 10.

[0027] By setting the buffer limit block 10, when the upper mold assembly moves upward, the buffer plate 5 moves upward under the action of the buffer spring 7, and the buffer limit block 10 can limit the movement range of the buffer plate 5 to prevent it from moving excessively.

[0028] Furthermore, in another embodiment, two lower limit blocks 11 are fixedly connected to both ends of the lower mold base 4, and upper limit blocks 12 that abut against the lower limit blocks 11 are fixedly connected to both sides of the upper mold base 1.

[0029] By abutting the lower limit block 11 of the lower die holder 4 against the upper limit block 15 of the upper die holder 1, the closing stroke of the upper and lower dies can be precisely controlled, preventing excessive forging from causing over-pressure deformation of the workpiece or wear of the die.

[0030] Furthermore, in another embodiment, guide mounting seats 13 are fixedly connected to the bottom four corners of the lower mold base 4, and a second guide rod 14 is fixedly connected to the top of the guide mounting seats 13. Guide sleeves 15 that are slidably connected to the second guide rod 14 are fixedly connected to the top four corners of the upper mold base 1.

[0031] The guide mounting seat 13 at the bottom of the lower mold base 4 and the second guide rod 14 cooperate with the guide sleeve 15 of the upper mold base 1 to provide guidance for the movement of the upper mold assembly, thereby preventing the upper mold assembly from swaying when it moves downward.

[0032] The working principle of one embodiment of this utility model is as follows:

[0033] First, the automotive part blank to be processed is positioned between the positioning blocks 9 around the top of the buffer plate 5. Then, the upper mold base 1 drives the upper template 2 and the upper forging block 3 to move downwards, and the second guide rod 14 slides within the guide sleeve 15 to ensure the upper mold assembly moves accurately in the vertical direction. When the upper forging block 3 contacts the blank and applies pressure, the buffer plate 5 slides downwards along the first guide rod 8 under pressure, compressing the buffer springs 7 around the bottom. The elastic deformation of the buffer springs 7 absorbs the impact force during the forging process, providing buffer protection. When the upper forging block 3 continues to press down, it cooperates with the lower forging block 6 in the through hole 51 to forge the blank. When the set forging stroke is reached, the upper limit blocks 12 on both sides of the upper mold base 1 and the lower limit blocks 11 at both ends of the lower mold base 4 abut against each other, restricting the upper mold assembly from continuing to move downwards and preventing excessive forging from damaging the mold. After forging is completed, the upper mold assembly returns to its original position, and the buffer plate 5 slides upwards along the first guide rod 8 under the elastic force of the buffer spring 7, allowing the formed automotive part to be removed.
