[0002] In the automotive industry, the manufacturing quality and precision of chassis components are crucial to the performance and safety of the entire vehicle. Traditional manufacturing processes for automotive chassis components often suffer from low efficiency, insufficient precision, and high costs.

[0003] With the rapid development of the automotive industry, the demand for chassis components is increasing, and the requirements for their quality and precision are also becoming higher and higher. As an important tool for chassis component manufacturing, the optimization of the performance and structure of stamping dies has become the key to improving production efficiency and product quality.

[0004] Past stamping dies may have the following shortcomings:

[0005] The hydraulic system is not precise and synchronized enough, resulting in poor stamping results and affecting the quality and precision of the parts.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example

[0029] like Figure 1-3 As shown, an embodiment of the present invention proposes a stamping die for manufacturing automobile chassis components, comprising a hollow base 1, a column 2 is fixedly connected to the hollow base 1, a crossbeam 3 is fixedly installed on the column 2, a large hydraulic cylinder 4 is inlaid and installed on the crossbeam 3, and a small hydraulic cylinder 5 is fixedly installed below the crossbeam 3, the output ends of the large hydraulic cylinder 4 and the small hydraulic cylinder 5 are fixedly connected to a mounting plate 6, an upper punch 7 is installed on the mounting plate 6 by fixing ear bolts, and a lower die 8 is fixedly installed with the fixing ear bolts below the hollow base 1, two vertical racks 9 are fixedly installed on the mounting plate 6, one end of the rack 9 is meshed with a gear plate 10, and the other end of the rack 9 is transmission-connected to a wheel plate 11, and an arc plate 12 is fixedly installed on the hollow base 1;

[0030] Hollow base 1: provides stable basic support for the entire mold.

[0031] Column 2: connects the hollow base 1 and the beam 3, and plays the role of supporting and fixing the beam 3.

[0032] Crossbeam 3: used for installing large hydraulic cylinder 4 and small hydraulic cylinder 5.

[0033] The large hydraulic cylinder 4 and the small hydraulic cylinder 5 jointly provide power to the mounting plate 6 to realize the stamping action.

[0034] Mounting plate 6: used to mount the upper punch 7 and transmit the power of the hydraulic cylinder.

[0035] The upper punch 7 and the lower die 8 cooperate with each other to complete the stamping of the chassis components.

[0036] Rack 9: cooperates with the toothed disc 10 and the wheel disc 11 to monitor the movement of the mounting disc 6.

[0037] Sprocket 10 and wheel 11 work together with rack 9 to achieve specific transmission or control functions.

[0038] Arc plate 12: fits against the side of the mounting plate 6 to guide or stabilize the movement of the mounting plate 6;

[0039] The working principle of this stamping die used in the manufacture of automobile chassis components is as follows:

[0040] During the stamping operation, the large hydraulic cylinder 4 and the small hydraulic cylinder 5 operate simultaneously. Due to the synchronous movement of their output ends, they provide a stable and powerful driving force for the mounting plate 6. The two small hydraulic cylinders 5 symmetrically arranged on both sides of the mounting plate 6 can further enhance the uniformity and stability of the driving force.

[0041] The mounting plate 6 moves downward under the push of the large and small hydraulic cylinders 5, driving the upper punch 7 to approach the lower die 8 below. The upper punch 7 and the lower die 8 cooperate with each other to stamp and form the raw materials of the automobile chassis parts placed between the two.

[0042] During the movement of the mounting plate 6, the rack 9 fixed on the mounting plate 6 moves accordingly. One end of the rack 9 is meshed with the gear plate 10 for transmission, and the other end is connected to the wheel plate 11 for transmission. Through the rotation of the gear plate 10 and the wheel plate 11, the movement state and position of the mounting plate 6 can be monitored.

[0043] The scale lines arranged vertically and parallel to the rack 9 can more accurately reflect the moving distance and direction of the mounting plate 6, and help the operator to accurately control the stroke and precision of the stamping.

[0044] The arc-shaped plate 12 on the hollow base 1 is fitted to the side of the mounting plate 6, guiding and stabilizing the movement of the mounting plate 6, ensuring the accuracy of its movement trajectory and reducing deviation and shaking.

[0045] like Figure 1 As shown, in some embodiments, the output ends of the large hydraulic cylinder 4 and the small hydraulic cylinder 5 move synchronously, ensuring that the thrust exerted on the mounting plate 6 during the up and down movement is evenly distributed, avoiding tilting or unstable movement of the mounting plate 6 due to uneven force, thereby ensuring the smoothness and accuracy of the stamping process.

[0046] like Figure 1 As shown, in some embodiments, there are two small hydraulic cylinders 5, which are symmetrically arranged on both sides of the mounting plate 6; the symmetrical arrangement can evenly balance the thrust on both sides of the mounting plate 6, avoiding the mounting plate 6 from tilting or offsetting due to excessive force on one side during movement, thereby ensuring the accuracy and stability of the stamping action.

[0047] In some embodiments, scale lines are provided on one side of the rack 9 .

[0048] In some embodiments, the scale lines are both vertical and parallel. The vertical scale lines can intuitively reflect the vertical movement distance of the mounting plate 6, helping the operator to accurately control the punching depth. The parallel scale lines can be used to measure the horizontal displacement of the mounting plate 6, helping to monitor the horizontal accuracy of the mounting plate 6 movement.

[0049] like Figure 2 As shown, in some embodiments, the shapes and sizes of the upper punch 7 and the lower die 8 are adapted to each other and are smaller than the diameter of the mounting plate 6; being smaller than the diameter of the mounting plate 6 makes the installation of the upper punch 7 and the lower die 8 on the mounting plate 6 more stable, avoiding loosening or displacement of the die due to the small contact area between the die and the mounting plate 6 during the stamping process, thereby ensuring the accuracy and stability of the stamping.

[0050] like Figure 2 As shown, in some embodiments, the side of the arc plate 12 is fitted onto the side of the mounting plate 6; when the mounting plate 6 moves, the arc plate 12 can guide it to move along a predetermined trajectory, preventing the mounting plate 6 from deviating or shaking, thereby ensuring the linearity and stability of the movement.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
