Description

Technical Field

[0001] This invention relates to the field of automotive sheet metal trimming and stamping technology, specifically to a stable automotive sheet metal trimming and stamping equipment. Background Technology

[0002] Automotive sheet metal parts refer to metal components manufactured using sheet metal processing techniques. They are primarily made from thin steel sheets, aluminum sheets, etc., and are produced through stamping, bending, and trimming processes using edge-trimming and stamping equipment. The die set of the edge-trimming and stamping equipment is a core component in automotive sheet metal part processing. Through precise structural design and collaborative working principles, it achieves efficient and accurate trimming of the edges of metal sheets.

[0003] When producing car doors, the excess edges need to be cut off after the upper and lower molds are pressed together. Then, a robotic arm with suction cups is used to pick up and cut the sheet metal parts. Because the sheet metal parts of the car doors are large and have a certain curvature, and need to be stamped in the middle of the sheet, the suction cup spacing of the robotic arm needs to be adjusted to be able to pick up the edges and corners of the scrap when cutting the scrap. After the sheet metal parts of the car doors are stamped in the middle, the scrap is prone to warping, wavy deformation or local dents due to internal stress release, stamping and stretching. The suction cups at some corners may not be able to fully adhere to the surface of the sheet due to the deformation of the workpiece, resulting in gaps between the suction cups and the workpiece, causing air leakage. The suction force decreases as the amount of air leakage increases. At best, it will cause the workpiece to shift during the handling process, affecting the positioning accuracy of subsequent processes. At worst, the insufficient suction force will cause the workpiece to fall, causing equipment collision damage or safety accidents. Summary of the Invention

After the stamping and trimming mechanism completes a stamping and trimming action, the main cutter cuts off the edge of the sheet metal, and the slitting cutter divides the waste into two symmetrical parts. During the upward movement of the stamping and trimming mechanism, the lifting component is activated simultaneously, driving the collection component to lift upward. Under the influence of gravity, the waste falls into the collection frame, and the directional collection avoids the waste from scattering and reduces the risk of equipment jamming.

[0016] This application provides a stable automotive sheet metal trimming and stamping equipment. During the descent of the stamping plate, the lifting component drives the collection component to flip. This synchronization ensures that the slit waste material falls directly onto the flipping plate, preventing waste material from falling into the stamping device or onto the ground due to positional deviation. This reduces the problem of waste material scattering and accumulation, and significantly improves the accuracy and efficiency of waste material collection.

[0017] This application provides a stable automotive sheet metal trimming and stamping equipment. By absorbing vibration energy through the deformation of buffer columns and springs, it can significantly reduce the collision noise between the first and second flipping plates and the first stamping plate, while also reducing the transmission of vibration to the main body of the equipment. This not only improves the working environment for operators but also avoids the long-term impact of vibration on the stability of the equipment's precision components.

[0018] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be further described in detail below with reference to figures. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0023] Please refer to Figures 1 to 8 A stable stamping and trimming equipment for automotive sheet metal parts includes: a stamping device 1, on which a plurality of columns 2 are symmetrically fixedly arranged, and a top plate 3 is fixedly arranged on the columns 2. A stamping cylinder 4 is fixedly arranged on the top plate 3, and an output shaft 5 is arranged on the stamping cylinder 4, the output shaft 5 passing through the top plate 3. The equipment also includes: a stamping and trimming mechanism 6, which is arranged on the stamping device 1. The stamping and trimming mechanism 6 includes a stamping plate 7 and a stamping plate 9 arranged on the columns 2. The stamping plate 7 is slidably arranged on the columns 2. A punch 8 is fixedly arranged at the bottom of the stamping plate 7. The stamping plate 9 is fixedly arranged on the columns 2. A concave die 10 is opened on the stamping plate 9. The stamping and trimming mechanism 6 is used to quickly and stably stamp and trim the sheet metal parts. The output shaft 5 is fixedly connected to the top of the first stamping plate 7. A telescopic spring 11 is sleeved on the column 2 between the second stamping plate 9 and the first stamping plate 7. A main cutter 12 is fixedly installed on the second stamping plate 9. A slitting cutter 13 is symmetrically installed on the main cutter 12. The main cutter 12 is located at the edge of the punch 8 and is adapted to its shape. The slitting cutter 13 is used to cut the waste material along the middle. A stamping plate 14 is placed between the punch 8 and the die 10.

[0024] The sheet metal 14 to be processed is placed in the corresponding position between the punch 8 and the die 10. Then, the stamping cylinder 4 is activated, the output shaft 5 extends and pushes the stamping plate 7 to slide downward along the column 2; the punch 8 moves downward with the stamping plate 7 and cooperates with the die 10 to stamp the sheet metal; at the same time, the main cutter 12 moves downward with the stamping plate 7 to precisely cut the edge of the sheet metal and remove excess material; the waste generated by cutting is separated under the action of the main cutter 12, and the slitting cutter 13 moves with the main cutter 12 to divide the waste into two parts along the center line. After stamping is completed, the stamping cylinder 4 drives the output shaft 5 to retract, and the stamping plate 7 returns to its original position upward along the column 2 with the assistance of spring force. Finally, the formed sheet metal part is removed by a robotic arm in conjunction with a suction cup.

[0025] Please refer to Figures 2 to 8 A stable automotive sheet metal trimming and stamping equipment includes a lifting and collecting mechanism 15, which is located on both sides of the stamping and trimming mechanism 6 and the stamping device 1. The lifting and collecting mechanism 15 includes a lifting component 16, a collecting component 24, and a buffer component 34. After being lifted by the lifting component 16, the lifting and collecting mechanism 15 uses the collecting component 24 to collect the waste material. Then, when the collecting component 24 descends, it is buffered by the buffer component 34.

[0026] After the stamping and trimming mechanism 6 completes one stamping and trimming action, the main cutter 12 cuts off the edge of the sheet metal, and the slitting cutter 13 divides the waste into two symmetrical parts. During the upward movement of the stamping and trimming mechanism 6, the lifting component 16 is started simultaneously, driving the collection component 24 to lift upward. Under the influence of gravity, the waste falls into the collection frame 33, and the directional collection avoids the waste from scattering and reduces the risk of equipment jamming.

[0027] Please refer to Figures 3 to 4 as well as Figure 6A lifting assembly 16 in a stable automotive sheet metal trimming and stamping equipment includes a first lifting rod 20 and a second lifting rod 21. Fixed rods 17 are symmetrically and fixedly mounted on both sides of the slitting blade 13 on a first stamping plate 7. A movable cavity 23 is symmetrically opened on a second stamping plate 9 directly below the fixed rods 17. Fixed shafts 18 are symmetrically fixedly mounted on the fixed rods 17, and torsion springs 19 are sleeved on the fixed shafts 18. One fixed shaft 18 is rotatably connected to the first lifting rod 20, and the other fixed shaft 18 is rotatably connected to the second lifting rod 21. The first lifting rod 20 and the second lifting rod 21 are oriented in opposite directions, and the longest distance between them is less than the length of the movable cavity 23. The first lifting rod 20 and the second lifting rod 21 are limited by the torsion springs 19, and a fixing block 22 is fixedly mounted at the bottom of each fixed rod 17.

[0028] Please refer to Figures 1 to 3 as well as Figures 5 to 7 A collection component 24 in a stable automotive sheet metal trimming and stamping equipment includes: a first flip plate 28 and a second flip plate 30. Connectors 25 are fixedly mounted on both sides of the second flip plate 30. Connecting shafts 26 are symmetrically mounted on both sides of the first flip plate 25, and second connectors 27 are rotatably mounted on each connecting shaft 26. The second connectors 27 are fixedly connected to the first flip plate 28 and the second flip plate 30 respectively. Notches 29 and 31 are provided through the opposite sides of the first flip plate 28 and the second flip plate 30. A stamping groove 32 adapted to the die 10 is provided on both the first flip plate 28 and the second flip plate 30. Collection frames 33 are provided on both sides of the first flip plate 28 and the second flip plate 30 located in the stamping device 1.

[0029] By lifting component 16 driving collection component 24 to flip during the descent of stamping plate 7, this synchronization ensures that the slit waste material can fall directly onto the flipping plate, avoiding waste material falling into the stamping device 1 or onto the ground due to positional deviation, reducing the problem of waste material scattering and accumulation, and greatly improving the accuracy and efficiency of waste material collection.

[0030] Please refer to Figure 8 A buffer assembly 34 in a stable automotive sheet metal trimming and stamping equipment includes: a buffer column 37 disposed above a second stamping plate 9; mounting holes 35 symmetrically opened above the second stamping plate 9; a buffer spring 36 disposed within the mounting holes 35; one side of the buffer spring 36 being fixedly connected to the buffer column 37; and the outer surface of the buffer column 37 sliding on the inner wall of the mounting hole 35. The weight of the first flipping plate 28 and the second flipping plate 30 is slightly greater than the contraction force of the buffer spring 36.

[0031] The buffer assembly 34 absorbs vibration energy through the deformation of the buffer column 37 and the spring, which can significantly reduce the collision noise between the first flip plate 28 and the second flip plate 30 and the first stamping plate 7, while also reducing the transmission of vibration to the main body of the equipment. This not only improves the working environment for operators, but also avoids the long-term impact of vibration on the stability of the precision components of the equipment.

[0032] When the stamping plate 7 is in the high, unstamped state, the lifting rods 20 and 21 maintain their initial posture under the elastic force of the torsion spring 19, and are perpendicular to the fixed rod 17. The stamping cylinder 4 drives the stamping plate 7 to move downward along the column 2, and the fixed rod 17 descends synchronously with the stamping plate 7. The lifting rods 20 and 21 gradually approach and fit against the notches 29 and 31. When the stamping plate 7 moves to be completely fitted against the stamping plate 14, the lifting rods 20 and 21 break free from the constraints of the notches 29 and 31 and enter the movable cavity 23. At this time, the lifting rods 20 and 21... When the second rod 21 and the fixed rod 17 are perpendicular again, when the first stamping plate 7 is driven to rise by the output shaft 5 of the stamping cylinder 4, the first lifting rod 20 and the second lifting rod 21, under the restriction of the fixed block 22, drive the first flipping plate 28 and the second flipping plate 30 to flip along the connecting shaft 26. Under the action of gravity, the waste on the first flipping plate 28 and the second flipping plate 30 falls into the collection frame 33. When the first stamping plate 7 continues to rise, the first lifting rod 20 and the second lifting rod 21 separate from the first flipping plate 28 and the second flipping plate 30. Then the first flipping plate 28 and the second flipping plate 30 fall and are buffered by the buffer column 37 and the buffer spring 36.

[0033] Based on all the above embodiments, the working principle of the present invention is as follows: The operator starts the equipment, and the robotic arm, in conjunction with a suction cup, places the stamping sheet 14 above the first flip plate 28 and the second flip plate 30. Then, the stamping cylinder 4 is activated, and the output shaft 5 extends, pushing the first stamping plate 7 downwards along the column 2. The punch 8 moves downwards with the first stamping plate 7, cooperating with the die 10 to stamp the sheet. Simultaneously, the main cutter 12 moves downwards with the first stamping plate 7, precisely trimming the edges of the sheet to remove excess material. The waste generated from trimming is separated by the main cutter 12, and the slitting cutter 13 moves with the main cutter 12, dividing the waste into two parts along the centerline. After stamping is complete, the stamping cylinder 4 drives the output shaft 5 to retract, and the first stamping plate 7 returns to its original position along the column 2 with the assistance of a spring. Finally, the formed sheet metal part is removed by the robotic arm in conjunction with the suction cup. During the above process, when the stamping plate 7 is in a high, unstamped state, the lifting rods 20 and 21 maintain their initial posture under the elastic force of the torsion spring 19, and are perpendicular to the fixed rod 17. The stamping cylinder 4 drives the stamping plate 7 to move downward along the column 2, and the fixed rod 17 descends synchronously with the stamping plate 7. The lifting rods 20 and 21 gradually approach and fit against the notches 29 and 31. When the stamping plate 7 moves to a point where it is completely fitted against the stamping plate 14, the lifting rods 20 and 21 break free from the constraints of the notches 29 and 31 and enter the movable cavity 23. At this time, the lifting rods 20 and 21... And the lifting rod 21 and the fixed rod 17 are once again in a vertical state. When the stamping plate 7 is driven to rise by the output shaft 5 of the stamping cylinder 4, the lifting rod 20 and the lifting rod 21, under the restriction of the fixed block 22, drive the flipping plate 28 and the flipping plate 30 to flip along the connecting shaft 26. Under the action of gravity, the waste on the flipping plate 28 and the flipping plate 30 falls into the collection frame 33. When the stamping plate 7 continues to rise, the lifting rod 20 and the lifting rod 21 disengage from the flipping plate 28 and the flipping plate 30. Then the flipping plate 28 and the flipping plate 30 fall and are buffered by the buffer column 37 and the buffer spring 36. By driving the collection component 24 to flip during the descent of the stamping plate 7, the lifting component 16 ensures that the cut waste can fall directly onto the flipping plate, avoiding the waste from falling into the stamping device 1 or onto the ground due to positional deviation, reducing the problem of waste scattering and accumulation, and greatly improving the accuracy and efficiency of waste collection. The buffer assembly 34 absorbs vibration energy through the deformation of the buffer column 37 and the spring, which can significantly reduce the collision noise between the first flip plate 28 and the second flip plate 30 and the first stamping plate 7, while also reducing the transmission of vibration to the main body of the equipment. This not only improves the working environment for operators, but also avoids the long-term impact of vibration on the stability of the precision components of the equipment.

Under the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
