Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, specifically a high-speed nut stamping and forming machine. Background Technology

[0002] Nut stamping is a process that uses molds and stamping equipment to deform metal sheets, and it is widely used in the furniture manufacturing industry. Its basic principle is to use molds to stretch, bend, and compress the metal sheet to ultimately form the desired nut shape.

[0003] Existing technology disclosure number CN221675626U discloses a stamping forming machine for square nuts, belonging to the field of nut processing technology. It includes a machine body and a stamping mechanism. The stamping mechanism for stamping square blanks is installed inside the machine body. The stamping mechanism includes a hydraulic cylinder, a punch, a punch head, a spring, a collar, a diagonal bar, and a clamping plate. The punch extending into the machine body is installed at the power output end of the hydraulic cylinder. During the downward movement of the punch, the bottom of the clamping plate first contacts the surface of the support. The punch head continues to move downward through the punch. During the downward movement, the spring is compressed, and at the same time, the diagonal bar moves into the punch, causing the clamping plates to move closer to each other. During the movement, the clamping plate contacts the side of the square blank and positions the blank to the top stamping position of the support before the punch contacts the blank, realizing automatic positioning of the blank, saving time and effort.

[0004] While the above-mentioned positioning has certain advantages, it still has certain drawbacks.

[0005] 1. During the stamping process of the nut, some iron filings will inevitably fly out and cannot be effectively blocked.

[0006] 2. Furthermore, if the equipment is damaged during use, it cannot be effectively and quickly disassembled and replaced, making the operation relatively troublesome. Utility Model Content

[0047] Example 1:

[0048] Please see Figures 1-5This utility model discloses a high-speed nut stamping and forming machine, comprising a C-shaped base 1, a discharge port 2 located on the front end face of the C-shaped base 1, a stamping groove 3 located on the inner bottom end face of the C-shaped base 1, wherein the discharge port 2 and the inner side of the stamping groove 3 are interconnected to allow waste material to be discharged, a hydraulic cylinder 4 fixedly connected to the upper end face of the inner side of the C-shaped base 1, a punch 401 installed at the output end of the hydraulic cylinder 4, a punch 402 fixedly connected to the lower end face of the punch 401, and a clamping device on the outer side of the punch 402. A limit device 5 is connected to the ring plate B6. The punch 402 is slidably connected to the center of the ring plate B6. Multiple automatic spring-loaded telescopic rods 7 are fixedly connected to the lower end face of the ring plate B6. Each automatic spring-loaded telescopic rod 7 is composed of two connecting rods inserted into each other and slidably connected. A spring is provided between the two rods to allow the automatic spring-loaded telescopic rods 7 to extend and return to their original position. The upper end face of the ring plate B6 is provided with a sliding groove 8. The outer side of the ring plate B6 is provided with a reserved opening 9. A large crown gear 10 is rotatably connected inside the ring plate B6. The lower end face of the large crown gear 10 is fixedly connected to... There is a connecting cylinder 11, and a worm gear 12 is fixedly connected to the lower end face of the connecting cylinder 11. A worm 13 is meshed on the worm gear 12. A knob 14 is fixedly connected to the front end face of the worm 13, and the knob 14 is located at the reserved opening 9 and rotates with the outer side of the ring plate B6. Multiple crown gears 15 are meshed on the upper end of the large crown gear 10. A screw 16 is fixedly connected to the center of the rear end face of the crown gear 15. A slider 17 is threaded on the screw 16. The slider 17 passes through the slide groove 8 via a connecting plate. A clamping plate A18 is fixedly connected. An automatic rebound telescopic rod 7 is fixedly connected to a ring plate A19 at its lower end. Two clamping plates B20 are slidably connected to the left and right ends of the outer side of the ring plate A19 through connecting plates. Multiple small rollers 21 are provided on the left end of the clamping plate B20. The small rollers 21 can prevent the material from directly rubbing against the surface of the clamping plate B20. An annular magnet 22 is fixedly connected to the lower end of the ring plate A19. A spring 23 is provided at the insertion and sliding connection between the inner side of the ring plate A19 and the clamping plate B20.

[0049] The working principle of a high-speed nut stamping machine based on Embodiment 1 is as follows:

[0050] First, when using the device, place it in the work area and connect it to an external power source to provide the necessary power.

[0051] Second, take the material to be stamped and move it to the lower end of the limiting device 5. Then, place the material between the two clamping plates B20 so that the material (usually carbon steel, alloy, etc., which can be attracted by magnets) comes into contact with the ring magnet 22 and is attracted. The clamping plates B20 are forced to open to the left and right, and at the same time, the spring 23 is stretched. When the spring 23 is stretched, it pulls the clamping plates B20 by rebounding, thus clamping the material between the two clamping plates B20 for limiting.

[0052] Third, the hydraulic cylinder 4 is then activated to drive the punch 402 to move through the punch cylinder 401, and at the same time, the limiting device 5 is moved to the inside of the stamping groove 3. During the stamping process, the two clamping plates B20 can also greatly prevent the flying of debris. When the stamping is completed, due to the attraction of the ring magnet 22, when the limiting device 5 moves out of the stamping groove 3, the nut can also be taken out of the stamping groove 3 together, making it convenient for personnel to remove and collect.

[0053] Fourth, when the limiting device 5 is damaged, the worm gear 13 can be rotated by turning the knob 14, which in turn drives the worm wheel 12 to drive the crown gear 10 to rotate through the connecting cylinder 11, which in turn drives the crown gear 15 to drive the slider 17 to move through the screw 16, which in turn moves the clamping plate A18 to loosen the clamping and fixing of the punch 402. This also allows the limiting device 5 to be quickly removed and replaced, which is convenient for personnel to use and has strong applicability.

[0054] This utility model provides an improved high-speed nut stamping machine. During stamping, the material is placed between two clamping plates B20. Simultaneously, the clamping plates B20 are opened to the left and right by force. The tension and rebound of the spring 23 can also clamp and limit the material. Then, the hydraulic cylinder 4 is activated to move the punch 402 and simultaneously move the limiting device 5 to the inside of the stamping groove 3, thus enabling mechanical stamping. At the same time, the clamping plates B20 can greatly prevent the splashing of debris. When the limiting device 5 is damaged, the knob 14 is turned to move the slider 17 and the clamping plate A18 to loosen the clamping and fixing of the punch 402, which can also achieve quick disassembly and replacement, making it more convenient to use.
