Detailed Implementation

[0030] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0031] Example 1

[0032] like Figures 1-3 As shown, this application provides a metal wire auxiliary stamping mechanism, comprising:

[0033] A first stamping structure 1 and a second stamping structure 2 are provided. The second stamping structure 2 is disposed on one side of the first stamping structure 1. Both the first stamping structure 1 and the second stamping structure 2 are provided with material channels. The first stamping structure 1 is used to flatten wire.

[0034] The second stamping structure 2 includes a main body 21, on which a stamping die 4 is provided. The stamping die 4 includes a stamping die base 41 and a stamping die head 42. The stamping die head 42 is vertically and vertically disposed above the stamping die base 41, and a cutter 422 is provided at the bottom of the stamping die head 42.

[0035] Both the inlet of the first stamping structure 1 and the outlet of the second stamping structure 2 are provided with a feeding structure 3.

[0036] Specifically, the first stamping structure 1 includes a first pressure plate 11, a second pressure plate 12, and a drive system 13. The second pressure plate 12 is disposed above the first pressure plate 11, and the drive system 13 drives the second pressure plate 12 to move up and down above the first pressure plate 11.

[0037] During operation, the drive system 13 drives the second pressure plate 12 to descend, causing the second pressure plate 12 to press the wire on the first pressure plate 11, flattening the wire. The flattened wire is then fed into the second stamping structure 2 by the feeding structure 3 for further processing.

[0038] More specifically, the feeding structure 3 of this application mainly consists of a drive assembly, a transmission assembly, a feeding roller assembly, and an adjustment assembly.

[0039] The drive assembly uses a servo motor, which is fixedly mounted on the frame of the stamping mechanism via a motor bracket made of high-strength metal to ensure the stability of the motor installation. The transmission assembly includes a synchronous belt and synchronous pulleys. The synchronous pulleys are respectively mounted on the output shaft of the servo motor and the shaft of the feeding roller, with the synchronous belt fitted between the two pulleys. When the servo motor starts, it transmits power to the shaft of the feeding roller via the synchronous belt, driving the feeding roller to rotate. The feeding roller assembly consists of a driving roller and a driven roller, which work together. The driving roller is fixedly connected to the shaft in the transmission assembly and rotates actively under power; the driven roller is mounted on an adjustable bracket via bearings and can rotate freely to accommodate wire feeding. The roller surface is made of a special rubber material with anti-slip textured spiral patterns, increasing friction with the wire and preventing slippage during feeding, ensuring the wire is stably and smoothly fed into the material channel of the stamping structure.

[0040] The adjustment assembly includes an adjustment screw and an adjustment bracket. The adjustment bracket has a threaded hole that mates with the adjustment screw. By rotating the adjustment screw, the bracket of the driven roller can be moved up and down, thereby adjusting the distance between the driving and driven rollers. This allows for flexible adjustment of the roller spacing according to different wire specifications, ensuring that the feeding structure 3 is suitable for conveying various wires and improving the equipment's versatility.

[0041] In addition, the feeding structure 3 is equipped with sensor detection devices, including photoelectric sensors and pressure sensors. The photoelectric sensors are installed at the inlet and outlet ends of the feeding roller assembly to detect the presence of wire and the feeding progress. When an abnormality is detected, a signal is promptly sent to the control system, causing the feeding structure 3 to stop operating and preventing malfunctions. The pressure sensor is installed on the bracket of the driven roller, monitoring the pressure of the roller on the wire in real time. Based on the pressure feedback, the speed of the servo motor is automatically adjusted to ensure that the wire is neither deformed due to excessive pressure nor slipped due to insufficient pressure during conveying, further improving the stability and accuracy of feeding.

[0042] The aforementioned metal wire auxiliary stamping mechanism, during operation, utilizes the feeding structure 3 located at the inlet and outlet to achieve continuous feeding and processing of metal wire. During feeding, the metal wire is compressed within the first stamping structure 1, flattening it to a predetermined thickness. After flattening, the metal wire enters the material channel of the second stamping structure 2 under the action of the feeding structure 3. When the metal wire reaches the stamping die 4 of the second stamping structure 2, a hydraulic cylinder drives the stamping die head 42 to descend, and the cutter 422 at the bottom of the stamping die head 42 stamps and cuts the wire to form the required shape and size. Completing the flattening and stamping / cutting operations within the same mechanism reduces the turnaround time in wire processing and improves processing efficiency. Furthermore, this avoids potential positioning deviations during transfer between different devices, helping to ensure product quality.

[0043] In one embodiment, the stamping die base 41 is provided with two notches 412, the two notches 412 penetrate the stamping die base 41 along the height direction of the stamping die base 41, and a cutting groove 413 is provided between the two stamping die bases 41.

[0044] The bottom of the stamping die head 42 is provided with two punch blocks 421, which correspond to the two notches 412 respectively, and the cutter 422 corresponds to the cutting groove 413.

[0045] This embodiment provides an installation method for the stamping die base 41. Specifically, the stamping die base 41 is provided with a mounting hole 411, which penetrates the stamping die base 41 along its height direction. The stamping die base 41 is fixedly connected to the main body 21 by bolts passing through the mounting hole 411.

[0046] Specifically, after the wire is conveyed to the designated position above the stamping die base 41, the hydraulic cylinder drives the stamping die head 42 to move downward. The two punches 421 at the bottom of the stamping die head 42 punch the flattened wire and insert it into the notch 412 of the stamping die base 41 to cut off a specific portion of the wire. The cutter 422 cooperates with the cutting groove 413 to punch and cut the wire, thereby cutting the wire. The processed wire is output from the discharge port of the second stamping structure 2.

[0047] Example 2

[0048] like Figures 1-5 As shown, this embodiment provides a specific implementation of the second stamping structure 2.

[0049] Specifically, the main body 21 is provided with a guide post 29, the top of the guide post 29 is fixedly provided with an upper template 23, the upper template 23 is provided with a drive cylinder 22, the guide post 29 is provided with a liftable lifting plate 24, the output end of the drive cylinder 22 is fixedly connected to the lifting plate 24, and the stamping die head 42 is provided at the bottom of the lifting plate 24.

[0050] The guide post 29 provides precise guidance for the lifting movement of the lifting plate 24 and the stamping die 42, ensuring the stamping die 42 remains stable and vertical during its up-and-down movement, reducing movement deviation and wobbling. This helps improve the accuracy and quality of stamping and cutting, ensuring uniform position and force for each stamping, and avoiding product defects caused by inaccurate stamping position or uneven force. The combination of the upper die plate 23 and the guide post 29 forms a robust frame structure that can effectively withstand the strong pressure and impact force generated by the drive cylinder 22. This structural design enhances the overall strength and rigidity of the second stamping structure 2, reduces the risk of deformation and damage during long-term use, and improves the reliability and service life of the equipment.

[0051] More preferably, a locking block 5 is provided on the top of the main body 21, and a locking groove 51 is formed between the locking block 5 and the top of the main body 21. Locking strips are provided on opposite sides of the stamping die base 41, and the locking strips are engaged in the locking groove 51.

[0052] A drive cylinder 6 is provided on the top of the main body 21. The output end of the drive cylinder 6 is engaged with the stamping die base 41, and the drive cylinder 6 drives the stamping die base 41 to slide in the slot 51.

[0053] During operation, the first feeding structure 3 feeds the wire into the first stamping structure 1 for flattening. Then, the second feeding structure 3 delivers the flattened wire to a designated position above the stamping die base 41 of the second stamping structure 2. The drive cylinder 22 pushes the lifting plate 24 down along the guide post 29, causing the stamping die head 42 to move downwards. The punch block 421 inserts into the notch slot 412 to fix the wire, and the cutter 422 cooperates with the cutting groove 413 to complete the cutting. After one stamping cycle, the drive cylinder 22 drives the stamping die head 42 to rise and reset. Simultaneously, the drive cylinder 6 can drive the stamping die head 42 to slide in the slot 51, facilitating fine-tuning of the die head 42's position to adapt to different processing requirements or to correct the die head position after multiple stamping cycles.

[0054] In this embodiment, the drive cylinder 6 can drive the stamping die base 41 to slide in the slot 51, which allows the position of the stamping die base 41 to be adjusted quickly and accurately according to different processing requirements in actual production. This eliminates the need for complex disassembly and reinstallation operations, saving adjustment time and improving production efficiency.

[0055] Furthermore, a first rotating shaft 27 is provided on the top of the main body 21, a second rotating shaft 25 is provided on the upper template 23, and a drive motor 28 for driving the second rotating shaft 25 to rotate is also provided on the upper template 23;

[0056] The second rotating shaft 25 is disposed opposite to the first rotating shaft 27, and a rotating belt 26 is disposed between the first rotating shaft 27 and the second rotating shaft 25;

[0057] The lifting plate 24 is equipped with a displacement detector 241, and the rotating belt 26 passes through the displacement detector 241 and is located between the first rotating shaft 27 and the second rotating shaft 25.

[0058] The displacement detector 241, in conjunction with the rotating belt 26, can detect the position of the lifting plate 24 in real time and with precision. This allows for precise control of the lifting height and speed of the lifting plate 24 during the stamping process, ensuring accurate pressing position and force of the stamping die 42, and greatly improving the stamping precision and product quality stability.

[0059] The drive motor 28 drives the rotating belt 26 to rotate, and combined with the feedback from the displacement detector 241, the position of the lifting plate 24 is automatically monitored and controlled. The equipment can automatically adjust the position of the lifting plate 24 according to the preset program, reducing manual intervention, improving production efficiency, and reducing the risk caused by human error.

[0060] Example 3

[0061] like Figures 1-5 As shown, this embodiment provides a wire forming machine, including the metal wire auxiliary stamping mechanism described above.

[0062] The wire forming machine integrates a metal wire auxiliary stamping mechanism, combining wire flattening, stamping and cutting, and subsequent forming processes into one integrated process. This reduces the handling and transportation of wire between different devices, significantly shortens the processing cycle, and improves overall production efficiency.

[0063] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.
