[0024] Reference Figure 1-Figure 6 A punching system for a guide baffle plate for a grass discharge port includes a die plate 000, an upper die assembly 100 and a lower die assembly 200. The upper die assembly 100 includes an upper die seat 101, an upper pad 102 connected to the upper die seat 101, a guide sleeve 103 and an upper stripping plate 104; the lower die assembly 200 includes a lower die seat 201, a vertical plate 202, a guide column 203, a lower pad, a feed protection groove 221 and a product chute 222; the vertical plate 202, the lower die seat 201 and the die plate 000 form a blanking space, the guide column 203 is fixed to the lower die seat 201, the guide column 203 and the guide sleeve 103 are slidably connected, and the upper pad 102 and the lower pad are correspondingly arranged; it is characterized in that: it includes a stamping die and a control module; the stamping die is sequentially arranged on the upper die seat 1 according to the stamping process 01 and the lower die base 201, including the first punching die, the second punching die, the third punching die, the first trimming die, the second trimming die, the forming die, the bending die, the side shaping die and the separation die; the control module is connected to the upper die assembly 100 and the lower die assembly 200 by signal and is used to complete the stamping control process of the grass discharge port guide baffle 400; wherein, the material strip 300 is punched out with a positioning hole 301 by the first punching die, the upper die base 101 is provided with a guide pin 1041, and the lower die base 201 is provided with a guide hole 223. When the stamping die is closed, the guide pin 1041 passes through the positioning hole 301 and is inserted into the guide hole 223 to guide the material strip 300, and the material strip 300 is stamped by the stamping die to generate the grass discharge port guide baffle 400.

[0025] According to the stamping process, the first punching die, the second punching die, the third punching die, the first trimming die, the second trimming die, the forming die, the bending die, the side shaping die and the separation die are sequentially arranged on the upper die assembly 100, so that the process is more reasonable, there is a good connection between the processes, and unnecessary waiting is avoided; by setting the positioning hole 301, the guide pin 1041 and the guide hole 223, the material strip 300 is guided to ensure the precise positioning of the stamping in the subsequent process, reduce the product scrapping due to the deviation of the material strip 300 during the stamping process, reduce the generation of waste materials, and reduce the material cost. The stamping control process of the grass discharge port guide baffle 400 is completed by setting the control module, and the quality problem of the grass discharge port guide baffle 400 is reduced. The problems of unreasonable process design, low material utilization rate, poor quality of stamped parts and low precision in the stamping system of the grass discharge port guide baffle 400 are solved.

[0026] The feed guard groove 221 guides the material strip 300 to the correct position of the mold, ensures that the material strip 300 is accurately aligned with the first punching mold, reduces the shaking of the material strip 300 when entering the mold, ensures that the material strip 300 smoothly enters the punching process, and avoids processing errors caused by the offset of the material strip 300; the product chute 222 ensures that the grass discharge port guide baffle 400 can slide out of the mold smoothly after the stamping is completed, thereby improving production efficiency, and the grass discharge port guide baffle 400 slides out along a predetermined path to facilitate subsequent collection and sorting.

[0027] The guide pin 1041 and the guide hole 223 are used together. The guide pin 1041 first passes through the material strip 300 and the upper positioning hole 301, and then is inserted into the guide hole 223 of the lower die base 201. On the one hand, it ensures that the upper die base 101 and the lower die base 201 can be accurately aligned each time they are closed, ensuring the consistent effect of each stamping, reducing product defects caused by position deviation, and improving product quality; on the other hand, it reduces the shaking of the mold during the stamping process, improves the stability of the mold, and avoids product quality problems caused by mold instability; in addition, in the stamping system of the grass discharge port guide baffle 400, multiple stamping operations may lead to cumulative errors. The design of the guide pin 1041 and the guide hole 223 can reduce the impact of such cumulative errors. The conical design of the guide pin 1041 can be more easily inserted into the guide hole 223, and can automatically adjust even if there is a slight position deviation, reducing the difficulty of alignment.

[0028] In some embodiments, the first punching die includes a first punching punch 105 provided on the upper die base 101 and a first punching die 204 provided on the lower die base 201; the second punching die includes a second punching punch 106 provided on the upper die base 101 and a second punching die 205 provided on the lower die base 201; the third punching die includes a third punching punch 107 provided on the upper die base 101 and a third punching die 206 provided on the lower die base 201; the first trimming die includes a first trimming punch 108 provided on the upper die base 101 and a first trimming die 207 provided on the lower die base 201; the second trimming die includes A second trimming punch 109 is arranged on the upper die base 101 and a second trimming die 208 is arranged on the lower die base 201; the forming die includes a forming punch 110 arranged on the upper die base 101 and a forming die 209 arranged on the lower die base 201; the bending die includes a bending punch 111 arranged on the upper die base 101 and a bending die 210 arranged on the lower die base 201; the side shaping die includes a side shaping punch 112 arranged on the upper die base 101 and a side shaping die 211 arranged on the lower die base 201; the separation die includes a separation punch 113 arranged on the upper die base 101 and a separation die 212 arranged on the lower die base 201.

[0029] In some embodiments, Figure 3 As shown, a first straight wedge block 1111 and a second straight wedge block 1112 are respectively provided on both sides of the bending punch 111.

[0030] The first straight wedge 1111 and the second straight wedge 1112 press the material strip 300 downward from both sides of the bending punch 111, so that both sides of the material strip 300 are perpendicular to the middle of the material strip 300. During the bending process, the material strip 300 will produce a certain elastic recovery, and the design of the first straight wedge 1111 and the second straight wedge 1112 helps to reduce the elastic recovery and improve the bending accuracy.

[0031] In some embodiments, Figure 4 As shown, a first oblique wedge block 2111, a second oblique wedge block 2112, a first guide rod 2113, a second guide rod 2114, a first driving member 2115 and a second driving member 2116 are provided on both sides of the side shaping die 211, two ends of the first guide rod 2113 are respectively fixed to the first oblique wedge block 2111 and the first driving member 2115, and two ends of the second guide rod 2114 are respectively fixed to the second oblique wedge block 2112 and the second driving member 2116.

[0032] The first guide rod 2113 and the second guide rod 2114 are used as transmission components. The first guide rod 2113 connects the first inclined wedge block 2111 and the first driving member 2115, so that under the action of the first driving member 2115, the first inclined wedge block 2111 moves along a predetermined horizontal direction to achieve the extrusion of the material strip 300 on one side; the second guide rod 2114 connects the second inclined wedge block 2112 and the second driving member 2116, so that under the action of the second driving member 2116, the second inclined wedge block 2112 moves along a predetermined horizontal direction to achieve the extrusion of the material strip 300 on the other side. Through the reverse movement of the first driving member 2115 and the second driving member 2116, the first inclined wedge block 2111 and the second inclined wedge block 2112 are smoothly separated from the material strip 300. On the one hand, the first oblique wedge block 2111 and the second oblique wedge block 2112 serve as the main force-bearing components for extruding the material strip 300; on the other hand, the first oblique wedge block 2111 and the second oblique wedge block 2112 serve as guiding elements to help the material strip 300 to be accurately positioned when entering the side shaping die 211, thereby ensuring the stable position of the material strip 300 during the forming process.

[0033] In some embodiments, Figure 5 As shown, the lower die base 201 is provided with a first waste chute 213, a second waste chute 214, a third waste chute 215, a fourth waste chute 216, a fifth waste chute 217 and a sixth waste chute 218 which pass through the lower die base 201; the first waste chute 213 is arranged on the first punching die 204, the second waste chute 214 is arranged on the second punching die 205, the third waste chute 215 is arranged on the third punching die 206, the fourth waste chute 216 is arranged on the first trimming die 207, the fifth waste chute 217 is arranged on the second trimming die 208, and the sixth waste chute 218 is arranged on the separation die 212.

[0034] Waste will be generated during the punching, trimming and separation processes. The provision of the first waste chute 213, the second waste chute 214, the third waste chute 215, the fourth waste chute 216, the fifth waste chute 217 and the sixth waste chute 218, on the one hand, enables the waste to be automatically discharged from the mold during the stamping production process to avoid waste blockage; on the other hand, the waste discharge process does not require frequent manual cleaning, which reduces labor intensity, reduces downtime for cleaning, and improves the continuity and efficiency of the production line; in addition, the waste is discharged through specific chutes, which makes it easier to classify and collect, and facilitates subsequent reuse or treatment; it is worth mentioning that a clear waste discharge path is conducive to integration with automated systems, such as waste collection systems or robot grasping systems, to achieve unmanned or less-manpowered production.

[0035] Preferably, the lower die base 201 is provided with three pairs of guide rulers 220, such as Figure 3~4 As shown, the guide rulers 220 are symmetrically arranged, the first pair of guide rulers 220 are respectively arranged on both sides of the forming die 209, the second pair of guide rulers 220 are respectively arranged on the rear side of the first straight wedge block 1111 and the rear side of the second straight wedge block 1112, and the third pair of guide rulers 220 are respectively arranged on both sides of the separation die 212.

[0036] After the material strip 300 is extruded by the forming die 209, the first straight wedge 1111 and the second straight wedge 1112, the width of the material strip 300 changes. The guide ruler 220 is set on both sides of the forming die 209, the rear side of the first straight wedge 1111 and the rear side of the second straight wedge 1112, which can correct the position of the material strip 300 in time, ensure the smooth transition of the material strip 300 between various processes, and improve the processing accuracy; the material strip 300 is separated at the separation die 212. If the position of the material strip 300 here is inaccurate, it will directly lead to uneven separation, and the formed material strip 300 will become scrap; the guide ruler 220 is set on the front side of the separation die 212 to ensure the precise guidance of the material strip 300, reduce the scrap rate caused by the misalignment of the material strip 300, and improve production efficiency and yield rate.

[0037] In some embodiments, Figure 4 As shown, the lower die base 201 is fixedly connected with at least two floating material guiding blocks 219 . The floating material guiding blocks 219 are of a “┏”-shaped structure and are symmetrically arranged on both sides of the first punching die 204 , the second punching die 205 and the third punching die 206 .

[0038] The floating material guide block 219 guides the material strip 300 to the correct position, ensuring that the material strip 300 can be accurately aligned with the first punching die 204, the second punching die 205 and the third punching die 206 during each punching, thereby improving the accuracy and consistency of the product. Since the floating material guide block 219 is a "┏"-shaped structure, on the one hand, it limits the left and right movement of the material strip 300, and on the other hand, it prevents the material strip 300 from being lifted up when the upper die assembly 100 moves upward after punching, resulting in position deviation.

[0039] In some embodiments, Figure 3~4 As shown, the upper mold assembly 100 also includes a laser ranging sensor 114, and the upper mold plate is provided with a sensing channel and a calibration pin 115. When the stamping mold is closed, the calibration pin 115 passes through the positioning hole 301 and is inserted into the calibration hole 224, and the laser ranging sensor 114 detects the position of the calibration pin 115 through the sensing channel.

[0040] During stamping, the calibration pin 115 first passes through the positioning hole 301 of the material strip 300, and then is inserted into the calibration hole 224 of the lower die base 201, which plays the role of aligning the upper die base 101 and the lower die base 201. The position of the calibration pin 115 is detected by the laser distance sensor 114, and the upper die assembly 100 and the lower die base 201 are monitored in real time to see whether they can be accurately aligned during each stamping. This helps to improve the position accuracy when the mold is closed, thereby ensuring the consistency and quality of the stamped parts.

[0041] In some embodiments, a grass discharge port material guide baffle stamping system also includes an alarm module, the alarm module includes a signal-connected electric field sensor, a microcontroller, a transceiver unit and an LED alarm light; the control module is signal-connected to the transceiver unit, the electric field sensor includes a plurality of sensing electrodes, and the plurality of sensing intervals are evenly distributed on the lower mold assembly 200 and are used to detect the transmission status of the material belt 300; the sensing electrode collects the status signal of the material belt 300 and transmits it to the microcontroller, the microcontroller filters, amplifies, converts analog to digital, and processes the signal, and then transmits the signal to the control module or the LED alarm light through the transceiver unit.

[0042] By setting up the alarm module, real-time monitoring and automatic control can be achieved, reducing manual intervention and improving the production efficiency of the stamping system. Timely monitoring and alarm mechanisms can reduce product defects caused by the position deviation of the material strip 300, thereby reducing the defective rate and improving product quality.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
