[0001] This utility model relates to the technical field of metal sheet processing, and specifically to a high-precision CNC stamping and forming device for metal sheet processing. Background Technology

[0002] In the field of sheet metal processing, stamping is an extremely common and crucial process, widely used in many industries such as automobile manufacturing, electronic equipment, and home appliance production.

[0003] However, after the stamping operation is completed, fragments of the sheet metal tend to accumulate in the discharge area of ​​traditional stamping equipment. Furthermore, traditional stamping equipment uses manual feeding, requiring operators to place the sheet metal directly onto the stamping die and frequently contact the equipment during the stamping process. This operating method exposes operators to high safety risks. Therefore, those skilled in the art have provided a high-precision CNC stamping forming device for processing thin metal sheets to solve the problems mentioned in the background art. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A high-precision CNC stamping and forming device for processing thin metal sheets includes a base. A limiting mold is fixedly installed on the top of the base by bolts. A limiting component for limiting the material plate is fixedly installed on one side of the top of the base. A top plate is fixedly installed around the top of the base by support rods. A cylinder is fixedly installed on the top of the top plate. A connecting component is fixedly installed on the output shaft of the cylinder. A stamping component is threaded on the bottom end of the connecting component. A discharge mechanism for assisting material discharge is installed on the top of the connecting component. A feeding mechanism for driving the material plate to move is installed on the bottom of the connecting component.

[0006] Preferably, the discharge mechanism includes a connecting ring, which is fixedly installed on the top of the connector. A telescopic rod is rotatably installed on one side of the connecting ring, and a first mounting member is rotatably installed in the middle of the telescopic rod. The first mounting member is fixedly connected to one end of the base.

[0007] Preferably, a second mounting component is rotatably mounted on one end of the telescopic rod, a first drive plate is fixedly mounted on one side of the second mounting component, a first limiting plate is fixedly mounted on both ends of the first drive plate, a discharge groove is opened at the bottom of the base, a limiting groove is opened on both sides of the discharge groove, the first drive plate is movably mounted in the discharge groove, and the two first limiting plates are movably mounted in the two limiting grooves respectively.

[0008] Preferably, the feeding mechanism includes a first mounting plate, which is movably mounted on a support rod. The middle part of the first mounting plate is fixedly connected to the bottom of the connecting member, and a third mounting member is fixedly mounted on one end of the first mounting plate.

[0009] Preferably, a drive rod is rotatably mounted on one side of the third mounting member, and a second mounting plate is fixedly mounted on the bottom end of the first mounting plate. The second mounting plate is movably connected to the support rod, and a first spring is fixedly mounted on one side of the second mounting plate. The other end of the first spring is fixedly connected to one side of the drive rod.

[0010] Preferably, the feeding mechanism further includes a third mounting plate, one end of which is fixedly connected to one end of the base, and an inclined plate is fixedly installed on one side of the top of the third mounting plate, the inclined plate being fixedly connected to the base.

[0011] Preferably, a fourth mounting plate is fixedly mounted on the other side of the top of the third mounting plate, a fourth mounting component is fixedly mounted on one end of the fourth mounting plate, a second driving plate is rotatably mounted on the fourth mounting component, a first connecting plate is fixedly mounted on the top of the second driving plate, and a second limiting plate is fixedly mounted on the top of the first connecting plate.

[0012] Preferably, a fifth mounting component is fixedly installed in the middle of one side of the second drive plate, a second connecting plate is rotatably mounted on the fifth mounting component, a second spring is fixedly installed on one side of the second connecting plate, and the other end of the second spring is fixedly connected to the fourth mounting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The designed discharge mechanism allows the stamped parts, driven by the cylinder, to fall into the discharge chute after stamping. When the cylinder drives upward, it moves the connecting ring upward, thereby driving the telescopic rod to rotate. Through the transmission of the first mounting component, the other end of the telescopic rod rotates in the opposite direction, driving the second mounting component to move the first drive plate within the discharge chute, thus pushing the material plate outward from one side of the discharge chute. This prevents material plate fragments from accumulating in the discharge chute, which could cause them to get stuck inside the base after multiple stampings.

[0015] 2. The feeding mechanism facilitates downward movement of the first mounting plate when the cylinder moves downward. Due to the pull of the first spring, the bottom of the drive rod engages in the punched hole. The inclined plate allows the bottom of the drive rod to rotate along it, pushing the material plate. When the cylinder moves upward, it moves the first mounting plate upward, driving the drive rod upward. This causes the bottom of the drive rod to disengage from the punched hole, and the punched hole, pushed by the drive rod, engages sequentially in the second limiting plate, thus limiting the material plate in conjunction with the limiting components. This facilitates automatic feeding, avoids the safety hazards of manual feeding, and effectively limits the material plate, thereby improving punching accuracy. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] This utility model discloses a high-precision CNC stamping and forming device for processing thin metal sheets. (Refer to...) Figure 1-5 The system includes a base 1, a limiting mold 2 fixedly mounted on the top of the base 1 by bolts, a limiting component 3 for limiting the material plate fixedly mounted on one side of the top of the base 1, a top plate 4 fixedly mounted around the top of the base 1 by support rods, a cylinder 5 fixedly mounted on the top of the top plate 4, a connecting component 6 fixedly mounted on the output shaft of the cylinder 5, a stamping component 7 threadedly mounted on the bottom end of the connecting component 6, a discharge mechanism for assisting discharge mounted on the top of the connecting component 6, and a feeding mechanism for driving the material plate to move mounted on the bottom of the connecting component 6.

[0024] By adopting the above technical solution, the present invention, through the set discharge mechanism, facilitates the stamping of the stamped part 7 by the drive of the cylinder 5, so that the material plate fragments can fall into the discharge groove 14. When the cylinder 5 is driven upward, it can drive the connecting ring 8 to move upward, thereby driving the telescopic rod 9 to rotate. Through the transmission of the first mounting part 10, the other end of the telescopic rod 9 rotates in the opposite direction, driving the second mounting part 11 to drive the first driving plate 12 to move in the discharge groove 14, thereby pushing the material plate outward from one side of the discharge groove 14. This design prevents material fragments from accumulating in the discharge chute 14, which could cause them to get stuck inside the base 1 after multiple stampings. The feeding mechanism allows the cylinder 5 to move downwards, causing the first mounting plate 16 to move downwards. Due to the pull of the first spring 20, the bottom of the drive rod 18 engages in the stamping hole. The inclined plate 22 allows the bottom of the drive rod 18 to rotate along it, pushing the material plate. When the cylinder 5 moves upwards, it moves the first mounting plate 16 upwards, driving the drive rod 18 upwards. This causes the bottom of the drive rod 18 to disengage from the formed hole, and the stamping hole, pushed by the drive rod 18, sequentially engages in the second limiting plate 27, thus working with the limiting component 3 to limit the material plate. This facilitates automatic feeding, avoids the safety hazards of manual feeding, and effectively limits the material plate, thereby improving stamping accuracy.

[0025] Reference Figure 1-5The discharge mechanism includes a connecting ring 8, which is fixedly installed on the top of the connecting member 6. A telescopic rod 9 is rotatably installed on one side of the connecting ring 8, and a first mounting member 10 is rotatably installed in the middle of the telescopic rod 9. The first mounting member 10 is fixedly connected to one end of the base 1. A second mounting member 11 is rotatably installed on one end of the telescopic rod 9, and a first drive plate 12 is fixedly installed on one side of the second mounting member 11. Both ends of the first drive plate 12 are fixedly installed with first limiting plates 13. A discharge groove 14 is opened at the bottom of the base 1, and limiting grooves 15 are opened on both sides of the discharge groove 14. The first drive plate 12 is movably installed in the discharge groove 14, and the two first limiting plates 13 are movably installed in the two limiting grooves 15 respectively.

[0026] By adopting the above technical solution, after the stamping part 7 is stamped by the cylinder 5, the material plate fragments can fall into the discharge groove 14. When the cylinder 5 is driven upward, it can drive the connecting ring 8 to move upward, thereby driving the telescopic rod 9 to rotate. Through the transmission of the first mounting part 10, the other end of the telescopic rod 9 rotates in the opposite direction, driving the second mounting part 11 to drive the first driving plate 12 to move in the discharge groove 14, thereby pushing the material plate outward from one side of the discharge groove 14.

[0027] Reference Figure 1-5 The feeding mechanism includes a first mounting plate 16, which is movably mounted on a support rod. The middle part of the first mounting plate 16 is fixedly connected to the bottom of the connecting member 6. A third mounting member 17 is fixedly mounted on one end of the first mounting plate 16. A drive rod 18 is rotatably mounted on one side of the third mounting member 17. A second mounting plate 19 is fixedly mounted on the bottom end of the first mounting plate 16. The second mounting plate 19 is movably connected to the support rod. A first spring 20 is fixedly mounted on one side of the second mounting plate 19. The other end of the first spring 20 is fixedly connected to one side of the drive rod 18.

[0028] By adopting the above technical solution, when the cylinder 5 drives downward, it drives the first mounting plate 16 to move downward. Due to the pull of the first spring 20, the bottom of the drive rod 18 is inserted into the hole formed by stamping. Furthermore, the setting of the inclined plate 22 enables the bottom end of the drive rod 18 to rotate along the inclined plate 22, thereby pushing the material plate.

[0029] Reference Figure 1-5The feeding mechanism also includes a third mounting plate 21, one end of which is fixedly connected to one end of the base 1. A ramp 22 is fixedly mounted on one side of the top of the third mounting plate 21, and the ramp 22 is fixedly connected to the base 1. A fourth mounting plate 23 is fixedly mounted on the other side of the top of the third mounting plate 21. A fourth mounting component 24 is fixedly mounted on one end of the fourth mounting plate 23. A second drive plate 25 is rotatably mounted on the fourth mounting component 24. A first connecting plate 26 is fixedly mounted on the top of the second drive plate 25. A second limiting plate 27 is fixedly mounted on the top of the first connecting plate 26. A fifth mounting component 28 is fixedly mounted in the middle of one side of the second drive plate 25. A second connecting plate 29 is rotatably mounted on the fifth mounting component 28. A second spring 30 is fixedly mounted on one side of the second connecting plate 29, and the other end of the second spring 30 is fixedly connected to the fourth mounting plate 23.

[0030] By adopting the above technical solution, the punched hole can be pushed by the drive rod 18 to rotate the second drive plate 25 on the fourth mounting part 24, thereby enabling the second limiting plate 27 to disengage from one hole. When the subsequent hole moves to the moving position, the tension of the second spring 30 can drive the second drive plate 25 to reset, so that the second limiting plate 27 can be re-engaged into the subsequent hole. In addition, with the setting of the limiting part 3, the material plate can be limited.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
