[0015] Compared with the prior art, the technical solution of the present application has the following beneficial effects: automobile parts stamping die and stamping equipment, through the setting of the stamping device, when the stamping operation starts, the hydraulic cylinder starts to push the hydraulic rod to move downward, and the hydraulic rod drives the punch and the guide plate connected to it to move downward together, and the guide blocks on both sides of the guide plate slide in the corresponding structure on the inner side of the bracket to ensure that the punch moves vertically downward without deviation. As the punch moves downward, the guide rod also drops. In this process, the lower pressure plate gradually approaches the lower die. When it contacts the workpiece, the lower pressure plate first contacts the workpiece to play a role of preliminary positioning and clamping. At this time, due to the reaction of the workpiece With force, the lower pressure plate pushes the guide rod to move upward, compressing the buffer spring. The buffer spring plays a buffering role to prevent the punch from causing damage to the workpiece and the mold due to excessive instantaneous impact force. The punch continues to move downward, driving the punch to approach the lower mold placed on the operating table. After the stamping is completed, the hydraulic cylinder drives the hydraulic rod to move upward, and the punch, guide plate, guide rod and lower pressure plate and other components rise accordingly. During the rising process, the buffer spring gradually stretches to help the lower pressure plate separate from the workpiece. When the punch rises to a certain height, the telescopic spring stretches to push the telescopic plate to move outward, so that the stop pawl is re-stuck in the stop groove to ensure the stability of the punch in the non-stamping state. When replacing, first stop the operation of the stamping equipment to ensure that the equipment is in a safe state, then lift the punch to a certain height so that the punch is completely separated from the lower die, then use a suitable tool, such as a wrench, to rotate the punch. Since the punch and the threaded groove at the bottom of the punch are threadedly connected, the punch gradually unscrews from the threaded groove during the rotation process. As the punch rotates, the telescopic spring, telescopic plate and stop pawl inside the thread block gradually relax, and the stop pawl disengages from the stop groove. When the old punch is completely unscrewed, prepare the new punch, align the threaded block on the new punch with the threaded groove at the bottom of the punch, and then slowly rotate the new punch to gradually screw it into the thread groove. During the screwing-in process, ensure that the punch and the punch remain vertical to avoid tilting. As the new punch is screwed in, the thread block enters the thread groove. When it is screwed in to a certain extent, the telescopic spring is compressed, pushing the telescopic plate to move outward, so that the stop pawl is stuck in the stop groove, thereby ensuring the stability of the new punch during operation. Finally, check whether the new punch is installed firmly. After confirmation, you can restart the stamping equipment and perform subsequent stamping operations. The detachable and replaceable punch greatly improves the flexibility of production. When facing the production needs of different types of automotive parts, you can quickly replace the appropriate punch according to the specific part shape, size and process requirements.

[0027] The stamping device 8 includes a hydraulic cylinder 801, a hydraulic rod 802, a first limiting groove 803, a punch 804, a guide plate 805, a guide block 806, a first slide groove 807, a first limiting block 808, a guide rod 809, a buffer spring 810, a lower pressing plate 811, a threaded groove 812, a punch 813, a threaded block 814, a telescopic groove 815, a telescopic spring 816, a telescopic plate 817, a stop pawl 818, a stop groove 819 and a lower mold 820. The upper surface of the bracket 7 is fixedly connected with the hydraulic cylinder 801, the hydraulic rod 802 is slidably connected inside the hydraulic cylinder 801, the inner surface of the bracket 7 is provided with a first limiting groove 803, one end surface of the hydraulic rod 802 is connected with the punch 804, and the surface of the punch 804 is fixedly connected with the guide The guide plate 805 is provided with a guide block 806 on both sides of the guide plate 805, a first slide groove 807 is provided inside the guide plate 805, a first limit block 808 is slidably connected to the inner wall surface of the first slide groove 807, a guide rod 809 is fixedly connected to the bottom end surface of the first limit block 808, a buffer spring 810 is wound around the outer wall of the guide rod 809, a lower pressing plate 811 is fixedly connected to the bottom surface of the guide rod 809, a threaded groove 812 is provided on the bottom surface of the punch 804, a punch 813 is threadedly connected to the inner wall surface of the threaded groove 812, a threaded block 814 is fixedly connected to the upper surface of the punch 813, a telescopic groove 815 is provided inside the threaded block 814, and a telescopic spring is fixedly connected to the inner wall surface of the telescopic groove 815 816, one end surface of the telescopic spring 816 is fixedly connected with a telescopic plate 817, the outer end surface of the telescopic plate 817 is fixedly connected with a stop pawl 818, the surface of the threaded groove 812 is provided with a stop groove 819, and the upper surface of the operating table 6 is fixedly connected with a lower mold 820. Through the setting of the stamping device 8, when the stamping operation starts, the hydraulic cylinder 801 is started to push the hydraulic rod 802 to move downward, and the hydraulic rod 802 drives the punch 804 and the guide plate 805 connected thereto to move downward together. The guide blocks 806 on both sides of the guide plate 805 slide in the corresponding structure on the inner side of the bracket 7 to ensure that the punch 804 moves vertically downward without deviation. As the punch 804 moves downward, the guide rod 809 also drops. In this process, The lower pressing plate 811 gradually approaches the lower die 820. When it contacts the workpiece, the lower pressing plate 811 first contacts the workpiece to play a role of preliminary positioning and clamping. At this time, due to the reaction force of the workpiece, the lower pressing plate 811 pushes the guide rod 809 to move upward, compressing the buffer spring 810. The buffer spring 810 plays a buffering role to prevent the punch 804 from causing damage to the workpiece and the die due to the instantaneous impact force of the punch 804. The punch 804 continues to move downward, driving the punch 813 to approach the lower die 820 placed on the operating table 6. After the stamping is completed, the hydraulic cylinder 801 drives the hydraulic rod 802 to move upward, and the punch 804, the guide plate 805, the guide rod 809 and the lower pressing plate 811 and other components rise accordingly. During the rising process, the buffer spring 810 gradually stretches.To help the lower pressing plate 811 to separate from the workpiece, when the punch 804 rises to a certain height, the telescopic spring 816 stretches, pushing the telescopic plate 817 to move outward, so that the stop pawl 818 is re-engaged in the stop groove 819, ensuring the stability of the punch 813 in the non-stamping state. When the punch 813 needs to be replaced, the operation of the stamping equipment is first stopped to ensure that the equipment is in a safe state, and then the punch 804 is lifted to a certain height so that the punch 813 is completely separated from the lower die 820. Then, use a suitable tool, such as a wrench, to rotate the punch 813. Since the punch 813 is threadedly connected to the thread groove 812 at the bottom of the punch 804, during the rotation process, the punch 813 is gradually screwed out of the thread groove 812. As the punch 813 rotates, the telescopic spring 816, the telescopic plate 817 and the stop pawl 818 inside the thread block 814 are gradually relaxed, and the stop pawl 818 is disengaged from the stop groove 819. When the old punch 813 is completely screwed out, the new one is inserted. The punch 813 is ready. The threaded block 814 on the new punch 813 is aligned with the threaded groove 812 at the bottom of the punch 804. Then the new punch 813 is slowly rotated to gradually screw into the threaded groove 812. During the screwing process, ensure that the punch 813 and the punch 804 remain vertical to avoid tilting. As the new punch 813 is screwed in, the threaded block 814 enters the threaded groove 812. When it is screwed in to a certain extent, the telescopic spring 816 is compressed, pushing the telescopic plate 817 to move outward, so that the stop pawl 818 is stuck in the stop groove 819, thereby ensuring the stability of the new punch 813 during the working process. Finally, check whether the installation of the new punch 813 is firm. After confirmation, the stamping equipment can be restarted for subsequent stamping operations. The detachable and replaceable punch 813 greatly improves the flexibility of production. When facing the production needs of different types of automotive parts, the appropriate punch 813 can be quickly replaced according to the specific part shape, size and process requirements.

[0028] Furthermore, multiple groups of shock-absorbing foot pads 3 are arranged on the bottom surface of the cabinet 1, and are symmetrically distributed at the four corners of the cabinet 1 with respect to the central axis of the cabinet 1. Through the arrangement of the shock-absorbing foot pads 3, the vibration generated during the stamping process can be effectively absorbed, reducing the impact of the vibration on the overall equipment, and improving the stability and precision of the equipment. At the same time, the symmetrical distribution design makes the cabinet 1 more evenly stressed, avoiding deformation or damage of the cabinet due to excessive local stress.

[0029] Furthermore, the outer wall size of the guide block 806 is consistent with the inner wall size of the first limit groove 803, and the outer wall size of the first limit block 808 is consistent with the inner wall size of the first slide groove 807. Through the setting of the first limit groove 803, the guide block 806, the first slide groove 807 and the first limit block 808, the mutual cooperation between the first limit groove 803 and the guide block 806 ensures that the punch 804 always maintains a vertical direction during the up and down movement without deviation, thereby improving the stamping accuracy. The mutual cooperation between the first slide groove 807 and the first limit block 808 further enhances the stability of the guide rod 809, ensuring that the lower pressure plate 811 can accurately position and press the workpiece, thereby improving the stamping quality.

[0030] Furthermore, the inner wall size of the thread groove 812 is consistent with the outer wall size of the thread block 814, and the telescopic plate 817 cooperates with the stop pawl 818 through the telescopic spring 816 to form a telescopic structure. Through the setting of the thread groove 812 and the thread block 814, the connection between the punch 813 and the punch 804 is made tighter and more stable, ensuring that the punch 813 will not loosen or fall off during the stamping process, thereby improving the safety and reliability of stamping.

[0031] Furthermore, the position of the stopping pawl 818 corresponds to the position of the stopping groove 819, and the outer wall size of the stopping pawl 818 is consistent with the inner wall size of the stopping groove 819. Through the setting of the stopping pawl 818, the phenomenon of the thread block 814 of the punch 813 being separated from the thread groove 812 during long-term use can be effectively prevented, thereby further increasing the stability of the connection between the punch 813 and the punch 804.

[0032] Furthermore, the positioning device 9 includes a fixed plate 901, a first motor 902, a first threaded rod 903, a stopper 904, a moving block 905, a moving plate 906, a positioning plate 907, a second limiting block 908, a fixed seat 909 and a second limiting groove 910. The upper surface of the punching device 8 is provided with a fixed plate 901, a side surface of the fixed plate 901 is fixedly connected to the first motor 902, an end surface of the first motor 902 is fixedly connected to the first threaded rod 903, a stopper 904 is provided in the middle part of the first threaded rod 903, the outer wall surface of the first threaded rod 903 is slidably connected to the moving block 905, and the upper surface of the moving block 905 is fixedly connected to A movable plate 906 is connected, a positioning plate 907 is fixedly connected to the lower surface of the movable plate 906, a second limiting block 908 is connected to the lower surface of one end of the movable plate 906, a fixed seat 909 is provided on the upper surface of one end of the punching device 8, a second limiting groove 910 is provided on the surface of the fixed seat 909, the bottom of the fixed plate 901 is fixedly connected to the upper end of one end of the lower mold 820, the bottom of the fixed seat 909 is fixedly connected to the upper end of the other end of the lower mold 820, through the setting of the positioning device 9, when it is necessary to punch the workpiece, the first motor 902 is first started, the first motor 902 drives the first threaded rod 903 to start rotating, and due to the setting of the stopper 904 , dividing the first threaded rod 903 into two working areas, making the moving direction of the moving block 905 clearer and more stable. As the first threaded rod 903 rotates, the moving block 905 starts to slide on the outer wall surface of the first threaded rod 903, and the sliding of the moving block 905 drives the moving plate 906 fixedly connected above to move together, and the positioning plate 907 connected below the moving plate 906 also moves accordingly, approaching the workpiece placed on the operating table 6. At the same time, the second limiting block 908 below one end of the moving plate 906 slides in the second limiting groove 910 opened on the surface of the fixed seat 909. The cooperation of the second limiting block 908 and the second limiting groove 910 ensures that the moving The stability and linearity of plate 906 during movement prevent it from deflecting or shaking. When positioning plate 907 contacts the workpiece, the position of moving block 905 is continuously adjusted so that positioning plate 907 applies appropriate pressure to the workpiece, firmly fixes the workpiece in a specific position, and provides reliable positioning guarantee for accurate stamping of stamping device 8. During the stamping process, positioning device 9 always maintains stable positioning of the workpiece to ensure the precision and quality of stamping. After the stamping is completed, the first motor 902 reverses to drive moving block 905, moving plate 906 and positioning plate 907 to move in the opposite direction, and releases the positioning of the workpiece so as to carry out the positioning and stamping operation of the next workpiece.

[0033] Furthermore, the threads of the first threaded rod 903 are symmetrically arranged with respect to the central axis of the stop block 904, and the outer wall size of the second limit block 908 is consistent with the inner wall size of the second limit groove 910. Through the arrangement of the first threaded rod 903, the limit block 908 and the second limit groove 910, the first threaded rod 903 ensures that the movement of the moving block 905 on the first threaded rod 903 is smoother. Due to the symmetry of the threads, no matter in which direction the moving block 905 moves, the thread pushing force it receives is evenly distributed, and there will be no unstable movement caused by the difference in the threads on one side. The outer wall size of the second limit block 908 is consistent with the inner wall size of the second limit groove 910, which ensures the linearity of the moving plate 906 during the movement process. The size matching enables the second limit block 908 to slide tightly in the second limit groove 910, thereby limiting the freedom of movement of the moving plate 906 in other directions and ensuring that it can only move along the predetermined straight line direction, so that the positioning plate 907 can be accurately aligned with the workpiece for positioning.

[0034] Furthermore, the collecting device 10 includes a second chute 1001, a second motor 1002, a second threaded rod 1003, a slider 1004, a push plate 1005, a slider 1006 and a collecting box 1007. The inner surface of the baffle 5 is provided with a second chute 1001, one end surface of the inner wall of the second chute 1001 is fixedly connected to the second motor 1002, one end of the second motor 1002 is fixedly connected to the second threaded rod 1003, the inner wall surface of the second chute 1001 is slidably connected to the slider 1004, and one end surface of the slider 1004 is fixedly connected to The push plate 1005, the inner wall surface of the second slide groove 1001 is fixedly connected with a slide rod 1006, the back of the cabinet 1 is connected with a collection box 1007, and the baffle plate 5 is provided with two groups on the surface of the workbench 4, and the inner side surfaces of the two groups of baffle plates 5 are provided with second slide grooves 1001, and the inner wall of one group of the second slide grooves 1001 is connected with a second threaded rod 1003, and the inner wall of the other group of the second slide grooves 1001 is fixedly connected with a slide rod 1006. Through the setting of the collecting device 10, after the stamping process is completed, some stamping waste or unqualified parts will remain in the operating On the workbench 6, at this time, the collecting device 10 is started, and the second motor 1002 located in one group of the second chutes 1001 starts to run, driving the second threaded rod 1003 to rotate. The slider 1004 is threadedly connected to the second threaded rod 1003, and starts to slide along the second chute 1001 under the rotation of the second threaded rod 1003. The push plate 1005 fixedly connected to one end of the slider 1004 also moves accordingly. At the same time, the slider 1004 in the other group of the second chute 1001 slides on the slide rod 1006 to provide auxiliary support and stabilize the push plate The function of 1005 is that as the push plate 1005 moves, the push plate 1005 pushes the stamping waste or unqualified parts on the operating table 6 toward the back of the cabinet 1. When the push plate 1005 pushes the waste to the opening on the back of the cabinet 1, the waste will fall into the collection box 1007. In this way, through the automatic operation of the collection device 10, the waste on the operating table 6 can be cleaned up in time, the working area can be kept clean, and preparations can be made for the next stamping operation. At the same time, the waste is collected in the collection box 1007, which is also convenient for subsequent unified treatment and recycling of the waste.

[0035] Furthermore, the second motor 1002 and the second threaded rod 1003 cooperate with each other to make the slider 1004 slide, and the outer wall size of the slider 1004 is consistent with the inner wall size of the second slide groove 1001. Through the setting of the second slide groove 1001 and the slider 1004, the stability of the movement of the push plate 1005 is guaranteed. The matching size ensures that the slider 1004 will not shake or deviate when sliding in the second slide groove 1001, ensuring that the push plate 1005 can push the waste smoothly, thereby improving the effect and reliability of waste cleaning, reducing friction and wear, and the tight fit reduces the gap between the slider 1004 and the second slide groove 1001, reducing the friction resistance during sliding, reducing the wear of components, and extending the service life of the collection device 10.

[0036] Working principle: First, place the blank of the automobile part to be stamped on the operating table 6, the positioning device 9 starts to work, the first motor 902 on one side of the fixed plate 901 starts, driving the first threaded rod 903 to rotate, and the moving block 905 on the first threaded rod 903 starts to slide under the push of the thread, and at the same time drives the moving plate 906 and the positioning plate 907 to move, and the second limit block 908 under one end of the moving plate 906 slides in the second limit groove 910 on the surface of the fixed seat 909 to ensure that the moving plate 906 moves in a straight line. The positioning plate 907 accurately fixes the blank part at a specific position on the operating table 6 to prepare for stamping. Then, the stamping device 8 starts, and the hydraulic cylinder 801 above the bracket 7 pushes the hydraulic rod 802 to move downward, and the hydraulic Rod 802 drives punch 804 and the guide plate 805 connected thereto to move downward together. The guide blocks 806 on both sides of the guide plate 805 slide in the first limiting groove 803 on the inner side of the bracket 7 to ensure that punch 804 moves vertically downward. As punch 804 moves downward, guide rod 809 also drops accordingly, and lower pressing plate 811 gradually approaches the part. When it contacts the part, lower pressing plate 811 first contacts the part to play a preliminary positioning and pressing role. At this time, due to the reaction force of the part, lower pressing plate 811 pushes guide rod 809 to move upward, compressing buffer spring 810, and punch 804 continues to move downward, driving punch 813 to approach lower die 820 placed on operating table 6 to punch the part. During the stamping process, The telescopic spring 816, telescopic plate 817 and stop pawl 818 inside the threaded block 814 can be adjusted for slight displacement as needed to ensure the stability of the stamping. After the stamping is completed, the hydraulic cylinder 801 drives the hydraulic rod 802 to move upward, and the punch 804, guide plate 805 and other components rise accordingly. The buffer spring 810 gradually stretches to help the lower pressure plate 811 to separate from the parts. When the punch 804 rises to a certain height, the telescopic spring 816 stretches to make the stop pawl 818 re-engage in the stop groove 819 to ensure the stability of the punch 813. The waste or unqualified parts generated during the stamping process will remain on the operating table 6. At this time, the collecting device 10 is started, and the second motor 1002 in one group of the second slide grooves 1001 drives the second screw The groove rod 1003 rotates to make the slider 1004 slide along the second slide groove 1001, and the push plate 1005 at one end of the slider 1004 pushes the waste to the collection box 1007 on the back of the cabinet 1. The sliders 1004 in the other set of second slide grooves 1001 slide on the slide rod 1006 to play a role in auxiliary support and stabilization of the push plate 1005. During the whole process, the shock-absorbing foot pads 3 at the bottom of the cabinet 1 effectively absorb the vibration generated during the stamping process and improve the stability of the equipment. The workbench 4 and the baffle 5 provide support and protection for each device. The cabinet door 2 can be opened when necessary to maintain and repair the equipment inside the cabinet 1. The model of the hydraulic cylinder 801 is CDM2B25, and the model of the first motor 902 is YE2-132S-4.The model of the second motor 1002 is Y315S-2, thus completing the use process of the automobile parts stamping die and stamping equipment.
