[0024] By placing the plate 12 to be processed on the table 11 of the lower die seat 2, and ensuring that the plate 12 is correctly placed along the length direction of the table 11; check and ensure that the positioning punch 6, the inner ring forming punch 7, the outer tooth forming punch 8 and the cutting punch 9 are respectively aligned with the positioning hole 13, the inner ring forming hole 14, the outer tooth forming hole 15 and the blanking hole 16 on the table 11; Ensure that the waste recovery box 17 and the finished product collection box 18 are respectively placed in the appropriate position below the positioning hole 13, the inner ring forming hole 14, the outer tooth forming hole 15 and the blanking hole 16, so as to collect the waste and finished products generated in the stamping process; When the stamping mechanism is started, the mounting plate 5 below the top plate 4 drives the positioning punch 6, the inner ring forming punch 7, the outer tooth forming punch 8 and the cutting punch 9 to move downward together; The positioning punch 6 first contacts the plate 12, ensuring that the plate 12 is accurately positioned during stamping to prevent displacement; Then, the inner ring forming punch 7 starts to stamp the plate 12 to form the inner ring part of the locking washer; Next, the outer tooth forming punch 8 continues to stamp the plate 12 to form the outer tooth part of the locking washer; Finally, the cutting punch 9 cuts the completed stamping locking washer from the plate 12 through the blanking hole 16, so that the finished product falls into the finished product collection box 18; During stamping, the waste below the positioning hole 13, the inner ring forming hole 14 and the outer tooth forming hole 15 will be directly dropped into the waste recovery box 17 by the stamping waste, realizing automatic collection of waste; The finished product collection box 18 is used to collect the locking washer finished product dropped through the blanking hole 16, facilitating subsequent packaging and transportation; The automobile locking washer stamping mechanism can efficiently and accurately produce locking washers that meet the requirements, while realizing automatic collection of waste and neat discharge of finished products, improving production efficiency and product quality.

[0025] Please refer to Figure 6 , Figure 7 , as an embodiment of the utility model, a plurality of damping reset assemblies 19 are arranged between the top plate 4 and the upper die seat 3, wherein the damping reset assemblies 19 are respectively arranged on both sides of the mounting plate 5.

[0026] The damping reset assembly 19 can ensure that the top plate 4 remains in a horizontal state under the weight of the mounting plate 5 and the punches, and prevent tilting or deformation caused by uneven weight distribution. By arranging the damping reset assembly 19 on both sides of the mounting plate 5, the stability and reliability of the entire stamping mechanism can be further improved. During the stamping process, when the top plate 4 drives the mounting plate 5, the positioning punch 6, the inner ring forming punch 7, the outer tooth forming punch 8, and the cutting punch 9 to move downward to stamp the plate 12, a large impact force is generated. The damping reset assembly 19 can absorb and disperse this impact force, reducing the vibration and impact on the upper die holder 3, the lower die holder 2, and the entire stamping mechanism. The damping reset assembly 19 typically includes springs, rubber pads, telescopic rods, or other elastic materials that can deform when subjected to pressure, thereby absorbing energy. When the impact force disappears, they can return to their original shape, ready for the next stamping. After completing a stamping, the top plate 4 needs to return to the initial position under the drive of the stamping mechanism for the next stamping. The damping reset assembly 19 not only provides damping effect during stamping, but also plays a resetting role when the top plate 4 rises. When the top plate 4 starts to rise, the elastic material in the damping reset assembly 19 releases the previously stored energy, pushing the top plate 4 back to the initial position quickly and smoothly, ensuring that the stamping mechanism can work continuously and stably, improving production efficiency, and prolonging the service life of each component.

[0027] Please refer to Figures 1 to 3 , as an embodiment of the utility model, the upper end of the storage table 11 is symmetrically provided with multiple sets of limiting shafts 20, wherein the limiting shafts 20 are arranged on both sides of the plate 12, and the upper end of the limiting shaft 20 is provided with a material guide groove 21 matched with the plate 12.

[0028] In the above-mentioned scheme, when the plate 12 to be processed is placed on the storage table 11, the limiting shaft 20 plays a positioning and guiding role. The limiting shaft 20 is arranged on both sides of the plate 12 to ensure that the plate 12 can be accurately aligned with the positioning hole 13, the inner ring forming hole 14, the outer tooth forming hole 15, and the blanking hole 16 on the storage table 11 when placed. Through the guidance of the limiting shaft 20, the plate 12 can be smoothly slid into the material guide groove 21, thereby avoiding the problem of inaccurate stamping or damaged mold caused by displacement or tilting of the plate 12 during stamping. The design of the limiting shaft 20 and the material guide groove 21 enables the plate 12 to maintain a stable position and posture during stamping, which helps to improve the precision and consistency of stamping, ensures that each locking washer can meet the design requirements, thereby reducing the scrap rate caused by deformation or damage of the plate 12, and improving production efficiency and economic benefits.

[0029] Please refer to Figure 5 , Figure 6As an embodiment of the utility model, the limiting pressing plate 10 is provided with a plurality of avoiding grooves 22 along the length direction, wherein the avoiding grooves 22 correspond to the top ends of the limiting shafts 20 arranged on the upper end of the storage table 11.

[0030] In the above scheme, during the stamping process, the limiting pressing plate 10 also moves downward along with the downward movement of the mounting plate 5 and the positioning punch 6, the inner ring forming punch 7, the outer tooth forming punch 8 and the cutting punch 9 driven by the top plate 4. If the limiting pressing plate 10 is not provided with the avoiding grooves 22, it may collide or interfere with the limiting shafts 20 on the storage table 11, resulting in obstruction or damage of the stamping process. By providing the avoiding grooves 22 on the limiting pressing plate 10 corresponding to the top ends of the limiting shafts 20, it can ensure that the limiting shafts 20 can move smoothly during the stamping process without being hindered by the limiting pressing plate 10. The design of the avoiding grooves 22 not only avoids the collision between the limiting pressing plate 10 and the limiting shafts 20, but also plays a role in protecting the limiting shafts 20 and the mold. During the stamping process, if the limiting shafts 20 are subjected to excessive pressure or friction, they may be deformed or damaged. However, the provision of the avoiding grooves 22 can reduce the generation of such pressure or friction, thereby prolonging the service life of the limiting shafts 20 and the mold. The limiting shafts 20 play a role in positioning and guiding during the stamping process, ensuring the stability of the plate 12 and the accuracy of the stamping. The provision of the avoiding grooves 22 further ensures the normal functioning of the limiting shafts 20, thereby improving the precision and consistency of the stamping. When the top plate 4 drives the mounting plate 5 and the punches to move downward, since the limiting shafts 20 are stably fixed and can move smoothly, the punches can accurately stamp the corresponding positions on the plate 12 to form the required locking washer, ensuring that the stamping mechanism works efficiently and stably, while improving the production efficiency and product quality.

[0031] Please refer to Figure 2 、 Figure 5 As an embodiment of the utility model, the lower mold base 2 is provided with guide sleeves 23 at the four corner positions, wherein the upper mold base 3 is provided with guide rods 24 adapted to the guide sleeves 23 at the four corner positions. The guide rods 24 are fixedly connected with the upper mold base 3, wherein the lower ends of the guide rods 24 are arranged in the guide sleeves 23 and are slidably connected therewith, and the upper ends of the guide rods 24 penetrate through the top plate 4 upward and are movably connected therewith.

[0032] In the above scheme, in the stamping process, the cooperation of the guide rod 24 and the guide sleeve 23 plays a key role in guiding and positioning. When the top plate 4 drives the upper die holder 3 and the positioning punch 6, the inner ring forming punch 7, the outer tooth forming punch 8, and the cutting punch 9 to move downward, the guide rod 24 will smoothly slide along the inner wall of the guide sleeve 23, ensuring that the upper die holder 3 can accurately move to the predetermined stamping position. The cooperation of the guide rod 24 and the guide sleeve 23 not only prevents the upper die holder 3 from shifting or tilting during the stamping process, but also improves the precision and consistency of the stamping, ensuring that each locking washer meets the design requirements. The cooperation of the guide rod 24 and the guide sleeve 23 also provides stable support for the upper die holder 3. During the stamping process, the upper die holder 3 will be subjected to a large impact force, but the guide rod 24 can disperse this impact force to the guide sleeve 23, thereby reducing the damage to the upper die holder 3 and its internal parts. At the same time, the sliding connection of the guide rod 24 and the guide sleeve 23 also plays a buffering role, which can absorb and disperse part of the impact force, improve the stability and durability of the stamping mechanism, and ensure that the stamping mechanism works efficiently and stably, while improving the production efficiency and product quality.

[0033] Please refer to Figure 2 , Figure 4 and Figure 5 , as an embodiment of the present application, the height limiting rod 25 is arranged below the top plate 4, wherein the lower end of the height limiting rod 25 penetrates the upper die holder 3 and extends downward; the upper end of the lower die holder 2 is provided with a buffer column 26, wherein the buffer column 26 corresponds to the height limiting rod 25.

[0034] In the above scheme, the main role of the height limiting rod 25 is to limit the descending height of the top plate 4 and the upper die seat 3 driven by the top plate 4 during the stamping process. When the top plate 4 drives the upper die seat 3 and each punch to move downward, the height limiting rod 25 will first contact the buffer column 26 on the lower die seat 2. This contact point is the termination point of the stamping, which ensures that the upper die seat 3 will not descend excessively to damage the mold or cause other accidents. By setting the height limiting rod 25, the excessive stamping caused by operation errors or equipment failures can be effectively prevented, thereby protecting the safety of the mold and the stamping mechanism. The cooperation of the buffer column 26 and the height limiting rod 25 also plays a role in buffering and shock absorption. When the height limiting rod 25 contacts the buffer column 26, the buffer column 26 can absorb and disperse the impact force, reducing the vibration and impact on the upper die seat 3, the lower die seat 2 and the entire stamping mechanism. The buffer column 26 is usually made of elastic materials. These materials can deform when subjected to pressure, thereby absorbing energy. When the impact force disappears, they can return to their original shape, ready for the next stamping. The design of the height limiting rod 25 and the buffer column 26 also facilitates the adjustment and calibration of the stamping mechanism. By adjusting the length of the height limiting rod 25 or the height of the buffer column 26, the gap between the upper die seat 3 and the lower die seat 2 can be accurately controlled, thereby meeting the stamping requirements of plate materials 12 of different thicknesses and sizes. This ensures that the stamping mechanism works efficiently and stably, while improving production efficiency and product quality.

[0035] Please refer to Figure 4 As an embodiment of the utility model, a partition 27 is arranged between the waste recovery box 17 and the finished product collection box 18, and the two ends of the partition 27 are fixedly connected with the base 1.

[0036] In the above scheme, the main role of the partition 27 is to separate the waste recovery box 17 and the finished product collection box 18, so that the waste generated during the stamping process and the finished products can be collected into different containers respectively. This helps to keep the working area clean and facilitates subsequent processing and recycling. By fixedly connecting the two ends of the partition 27 with the base 1, the stable position and posture of the partition 27 during the stamping process can be ensured, and the partition 27 will not move or deform due to vibration or impact force. This further improves the collection efficiency of waste and finished products and reduces the situation of scattering and missing.
