During the stamping process, the stamping part 4 needs to move up and forward according to the stamping process, and a ∏-shaped limiter 332 is set to limit the moving direction of the stamping part 4, further improving the stamping accuracy, and solving the problem that the existing bottom guard plate mounting bracket stamping system only relies on an external feeding mechanism to move the stamping part 4, and the control of the stamping part 4 is not accurate enough. The ∏-shaped limiter 332 limits the moving height and left and right moving range of the stamping part 4.
[0027] When the upper die assembly 2 and the lower die assembly 3 are closed, the guide pin 32 is inserted into the guide sleeve 23 to ensure that the upper die assembly 2 and the lower die assembly 3 are aligned during stamping, thereby improving the stamping accuracy.
[0028] The upper die assembly 2 and the lower die assembly 3 are both continuous dies, which form multiple features of the stamping part 4 in one stroke, reducing the number of stamping times, thereby saving time and cost.
[0029] In order to make the stamping process smoother, a feed port is provided on the side of the lower die assembly 3 close to the punching die 5, and a finished product chute is provided on the side of the lower die assembly 3 close to the separation die 10; the feed port is used to transfer the stamping parts 4, and the setting of the finished product chute ensures that the finished product can be smoothly and safely removed from the die and transported to the designated location.

[0031] During the stamping process, the upper die assembly 2 moves downward, and the first punch 51, the second punch 52 and the third punch 53 punch out the positioning hole 41 on the stamping part 4. Waste will be generated during the punching process. These wastes will slide out of the lower die assembly 3 along the first waste chute, the second waste chute and the third waste chute respectively, ensuring the normal operation of the bottom guard plate mounting bracket stamping system and the quality of the stamping part 4.
[0032] The first punch 51 is located in the middle of the stamping part 4, the second punch 52 and the third punch 53 are respectively located on both sides of the stamping part 4, the first punch 51, the second punch 52 and the third punch 53 are distributed at equal intervals, and the first punch 51, the second punch 52 and the third punch 53 act simultaneously to accelerate the process of punching the positioning hole 41, thereby improving production efficiency.

[0035] In some embodiments, Figures 3-5 As shown, the outer trimming die set 7 includes a first outer trimming punch 71 and a second outer trimming punch 72 connected to the upper die base 21 and symmetrically arranged along the central axis of the upper die base 21, and a first outer trimming die 73 and a second outer trimming die 74 connected to the lower pad 33. The lower die assembly 3 is respectively provided with a sixth waste chute and a seventh waste chute corresponding to the first outer trimming punch 71 and the second outer trimming punch 72. The sixth waste chute and the seventh waste chute both pass through the lower die base 31 and the lower pad 33.
[0036] The first outer trimming punch 71 cooperates with the first outer trimming die 73 to cut off one side of the stamping part 4, and the second outer trimming punch 72 cooperates with the second outer trimming die 74 to cut off the other side of the stamping part 4. The waste generated during the cutting process slides out of the lower die assembly 3 along the sixth waste chute and the seventh waste chute respectively, so as to ensure the normal operation of the bottom guard plate mounting bracket stamping system and the quality of the stamping part 4.
[0037] In some embodiments, Figure 3~4 As shown, the forming module group 8 includes a first bending punch 81, a second bending punch 82, a third bending punch 83 and a fourth bending punch 84 connected to the upper die base 21, and a first bending groove 85, a second bending groove 86, a third bending groove 87 and a fourth bending groove 88 located on the lower pad 33 and arranged corresponding to the first bending punch 81, the second bending punch 82, the third bending punch 83 and the fourth bending punch 84; wherein the first bending punch 81 and the second bending punch 82 are symmetrically arranged along the central axis of the upper die base 21, and the third bending punch 83 and the fourth bending punch 84 are symmetrically arranged along the central axis of the upper die base 21.
[0038] The first bending punch 81 and the second bending punch 82 are symmetrically arranged, and the third bending punch 83 and the fourth bending punch 84 are symmetrically arranged to ensure that the stamping part 4 is subjected to uniform force during the bending and forming process, reduce deformation or warping caused by uneven force on one side, and improve the dimensional accuracy and shape consistency of the stamping part 4. The forming module 8 is stamped and formed in one time to reduce the accumulation of errors. According to the specific shape of the required stamping part 4, the forming module 8 is designed into a corresponding shape. During stamping, the first bending punch 81, the second bending punch 82, the third bending punch 83 and the fourth bending punch 84 bend the stamping part 4, and are respectively embedded in the first bending groove 85, the second bending groove 86, the third bending groove 87 and the fourth bending groove 88, so that the stamping part 4 is bent and accurately formed.
[0039] In some embodiments, Figure 3~4 As shown, the shaping mold group 9 includes a first shaping punch 91, a second shaping punch 92, a third shaping punch 93 and a fourth shaping punch 94 connected to the upper mold base 21, and a first shaping groove 95, a second shaping groove 96, a third shaping groove 97 and a fourth shaping groove 98 located on the lower pad 33 and corresponding to the first shaping punch 91, the second shaping punch 92, the third shaping punch 93 and the fourth shaping punch 94; wherein the first shaping punch 91 and the second shaping punch 92 are symmetrically arranged along the central axis of the upper mold base 21, and the third shaping punch 93 and the fourth shaping punch 94 are symmetrically arranged along the central axis of the upper mold base 21.
[0040] The forming module 8 is mainly used to shape the stamping part 4 into a basic shape, but there may be certain size and shape deviations during the forming process. The shaping module 9 further fine-tunes and corrects to eliminate deviations, improve the dimensional accuracy of the parts, ensure that the geometric shape of the stamping part 4 is more accurate, ensure that the bending forming effect of the stamping part 4 is consistent, and reduce bending rebound. Although the shaping module 9 increases the production steps, the proportion of defective products can be reduced through precise shaping, the rework rate can be reduced, and the overall production efficiency can be improved.
[0041] The symmetrically arranged first shaping punch 91 and second shaping punch 92, as well as the symmetrically arranged third shaping punch 93 and fourth shaping punch 94, ensure that the stamping part 4 is subjected to uniform pressure during the shaping process, reduce deformation or warping of the stamping part 4 due to uneven force on one side, and improve the accuracy of the size of the stamping part 4. The shaping die set 9 completes the shaping in one punching, reducing the accumulation of errors. According to the specific shape of the required stamping part 4, the shaping die set 9 is designed into a corresponding shape. During stamping, the first shaping punch 91, the second shaping punch 92, the third shaping punch 93 and the fourth shaping punch 94 shape the stamping part 4 and are respectively embedded in the first shaping groove 95, the second shaping groove 96, the third shaping groove 97 and the fourth shaping groove 98 to fine-tune the stamping part 4.
[0042] In some embodiments, Figures 3-5 As shown, the separation module 10 includes a separation punch 101 connected to the upper die base 21 and a separation die 102 connected to the lower pad 33. The separation punch 101 is located on the central axis of the upper die base 21. The lower die base 31 is provided with an eighth waste chute corresponding to the separation punch 101. The eighth waste chute runs through the lower die base 31 and the lower pad 33.
[0043] The stamping part 4 is stamped by the punching die 5, the inner trimming die 6, the outer trimming die 7, the forming die 8 and the shaping die 9 to form a connecting bridge in the middle of the stamping part 4. The separation punch 101 cooperates with the separation die 102 to cut off the connecting bridge, so that the stamping parts on both sides of the connecting bridge are separated to become independent finished products; the waste generated in the cutting process slides out of the lower die assembly 3 along the eighth waste chute to ensure the normal operation of the bottom guard plate mounting bracket stamping system and the quality of the stamping part 4.

The lower die assembly 3 is provided with a ninth waste chute and a tenth waste chute corresponding to the fourth punch 211 and the fifth punch 212.
[0045] During stamping, the fourth punch 211 and the fifth punch 212 punch holes in the stamping part 4, and the waste generated by the punching slides out of the lower die assembly 3 along the ninth waste chute without interfering with subsequent processing steps; the fourth punch 211 and the fifth punch 212 evenly apply force to both sides of the stamping part 4 to prevent the stamping part 4 from shifting, thereby ensuring the quality of the stamping part 4.
[0046] In some embodiments, Figure 4 As shown, the bottom pad 33 is connected to a floating material guide block 333, and the floating material guide block 333 is located on both sides of the inner trimming module 6. Figure 3 As shown, the upper die base 21 is provided with an inner guide column 213 and a nitrogen cylinder 214, and the lower pad 33 is provided with an inner guide hole 334.

During stamping, the other end of the inner guide column 213 passes through the upper stripping plate and is inserted into the inner guide hole 334, and the other end of the nitrogen cylinder 214 passes through the upper stripping plate to fix the stamping part 4.
[0047] The floating material guide block 333 guides the stamping part 4 to move forward smoothly, preventing the stamping part 4 from deviating or causing unnecessary deformation. The floating material guide block 333 accurately positions the stamping part 4 within the working area of the inner trimming module 6, ensuring that the position of the stamping part 4 is consistent during each stamping, thereby ensuring the consistency and quality of the finished product.
[0048] The use of the inner guide pin 213 and the inner guide hole 334 provides high-precision guidance, ensuring that the upper mold assembly 2 and the lower mold assembly 3 are accurately aligned when closed, thereby ensuring that each stamping action can achieve the same effect and ensure the consistency of product size, precision and quality. The nitrogen cylinder 214 is used to fix the stamping part 4. When the stamping starts, the nitrogen cylinder 214 provides a stable support force to make the stamping part 4 close to the lower mold assembly 3, preventing the stamping part 4 from being displaced or deformed during the stamping process, thereby ensuring the quality of the stamping part 4. In addition, when the upper mold assembly 2 and the lower mold assembly 3 are separated, the nitrogen cylinder 214 fixes the stamping part 4 to avoid the stamping part 4 moving with the upper mold assembly 2.
[0049] In some embodiments, a bottom guard plate mounting bracket stamping system also includes a driving module and a control module; the driving module includes a driving unit, which is connected to the upper die base 21 and drives the upper die base 21 to move linearly up and down; the control unit includes a signal-connected microcontroller, a photoelectric sensor and a transceiver unit, the photoelectric sensor is used to detect the position and status of the stamping part and send information to the microcontroller through the transceiver unit, and the microcontroller processes the signal and controls the driving unit.
[0050] The driving unit is specifically one of a hydraulic cylinder, a pneumatic cylinder or a servo motor; the photoelectric sensor monitors the position and state of the stamping part in real time and converts the detected light signal into an electrical signal. The signal output end of the photoelectric sensor is connected to the signal input end of the transceiver unit. The transceiver unit is specifically Bluetooth. The microcontroller receives information from the transceiver unit and processes the information according to a preset program to control the action of the driving unit, thereby controlling the movement of the upper die. The production efficiency is improved by setting the driving module and the control module.
