[0026] In use, the servo-driven material guide mechanism 201 delivers the hardware stamping material to the material conveying channel, and through the drive wheels 207 of the mounting seat one 202 and the mounting seat two 206, the material is smoothly fed. The design of the material guide mechanism 201 can be easily disassembled, facilitating maintenance and replacement.

[0027] The punch part 301 and the punch-shear part 302 are connected with the positioning plate 3, and the connection between the upper die seat 1 and the lower die seat 2 is provided with a guide structure.

[0028] The lower die seat 2 is also provided with a forming insert, two rapid cooling systems 4 and a detection system 5. The rapid cooling system 4 is symmetrically arranged on both sides of the forming insert, and the detection system 5 is connected with the rapid cooling system 4. The rapid cooling system 4 includes a plurality of nozzles 401 and control valves 402 connected with the nozzles 401. The control valves 402 are arranged on the lower die seat 2 in a linear manner. The detection system 5 includes a mounting seat three 503, a strain sensor 501 and a temperature sensor 502 arranged on the mounting seat. The mounting seat three 503 is provided with a controller, and the controller is connected with the strain sensor 501 and the temperature sensor 502.

[0029] The rapid cooling system 4 is provided in the embodiment, which sprays cooling medium such as cold air through the nozzles 401 to rapidly reduce the temperature of the forming insert, so as to reduce the influence of temperature on the properties of the material and improve the forming effect. The control of the cooling system is connected with the detection system 5 to ensure the synchronization of the cooling effect and the forming process. The detection system 5 monitors the mold state in real time through the strain sensor 501 and the temperature sensor 502, transmits the data to the controller, and performs feedback adjustment to achieve the best stamping effect.

[0030] The ultrasonic auxiliary stamping die group 203 arranged in the material conveying channel provides additional energy according to the preset frequency and intensity during the stamping process, helps to improve the plasticity of the material, improves the stamping quality, and reduces deformation or cracks. Finally, the application of the ejection spring 103 ensures that the finished product can be smoothly separated from the mold after the stamping is completed, avoiding the jamming of the material.

[0031] Further, the punch part 301 and the punch-shear part 302 are arranged corresponding to the position of the forming insert of the upper die seat 1, and the punch part 301 and the punch-shear part 302 are connected with the positioning plate 3. The connection between the upper die seat 1 and the lower die seat 2 is provided with a guide structure.

[0032] When the mold is closed, the punch part 301 pushes the material downward to perform bending or punching, and when the upper die holder 1 moves, the punching shear part 302 can be engaged with the corresponding part on the lower die holder 2 to complete the shearing action.

[0033] Further, the positioning plate 3 is provided with guide posts one 102 on both sides, and the lower die holder 2 is provided with guide posts two 204 on both sides, and the guide posts one 102 and the guide posts two 204 are coaxially arranged, and the end of the guide posts two 204 is provided with a control button 205.

[0034] Guide posts one 102 and guide posts two 204: The positioning plate 3 is provided with guide posts one 102 on both sides, and the lower die holder 2 is provided with guide posts two 204 on both sides, and the guide posts one 102 and the guide posts two 204 are coaxially arranged. This coaxial arrangement helps to ensure the alignment of the upper die and the lower die during movement. When the two ends of the guide posts one 102 and the guide posts two 204 are in contact, the control button 205 is pressed down, and the control button 205 is connected with the controller to realize synchronous operation.

[0035] Further, the guide structure includes a plurality of guide rods, the guide rods are respectively connected to the upper die holder 1 and the lower die holder 2, the connection between the guide rods and the upper die holder 1 is provided with a tension adjusting ring one 104, and the connection between the guide rods and the lower die holder 2 is provided with a tension adjusting ring two 208.

[0036] The connection between the guide rods and the upper die holder 1 is provided with a tension adjusting ring one 104, and the connection between the guide rods and the lower die holder 2 is provided with a tension adjusting ring two 208. These adjusting rings can optimize the fastening degree of the mold to adapt to different processing needs and ensure the stability and consistency when the mold is closed.

[0037] Further, the connection between the upper die holder 1 and the positioning plate 3 is also provided with a plurality of buffer springs 101, and the buffer springs 101 are arranged in a matrix manner.

[0038] The connection between the upper die holder 1 and the positioning plate 3 is provided with a plurality of buffer springs 101, and the buffer springs 101 are arranged in a matrix manner. The function of these buffer springs 101 is to absorb impact force, reduce the vibration generated during the closing and opening of the mold, reduce the risk of damage, and at the same time improve the durability and working stability of the mold.

[0039] Further, the lower die holder 2 is internally provided with a stripping spring 103, and the stripping spring 103 is arranged at the bottom of a forming insert, and the forming insert includes a concave die.

[0040] The stripper spring 103 is arranged at the bottom of the forming insert. After the stamping or shearing operation is completed, the material will rely on the restoring force of the spring to separate. In the specific process, the spring is compressed. When the upper die is separated (i.e. the mold is opened), the stripper spring 103 will quickly restore its original state, thereby pushing the workpiece after forming or blanking out of the die, reducing the need for external intervention of workers or machines, and ensuring smooth operation of the production line.

[0041] Further, the mounting seat one 202 and the mounting seat two 206 are arranged below the material conveying channel, and the mounting seat one 202, the mounting seat two 206 and the mounting seat three 503 are arranged horizontally with the lower die seat 2, wherein the mounting seat three 503 is arranged above the material conveying channel.

[0042] The hardware stamping material is conveyed to the material conveying channel, and the driving wheels 207 of the mounting seat one 202 and the mounting seat two 206 are used to realize stable material feeding. In this process, the stamping process, cooling and detection of the forming insert are sequentially performed. The mounting seat three 503 is arranged above the finished hardware, which facilitates the detection of the strain sensor 501 and the temperature sensor 502.

[0043] Further, the material conveying channel is provided with an ultrasonic auxiliary stamping module 203, which includes an ultrasonic generator, a transducer and an acoustic wave matcher, and the ultrasonic generator is connected with the controller.

[0044] The ultrasonic generator is responsible for generating a high-frequency electrical signal. The transducer receives an electrical signal above 20 kHz. The transducer converts the electrical signal generated by the ultrasonic generator into mechanical vibration. The acoustic wave matcher improves the transmission efficiency of ultrasonic waves in the material, so as to maximize the vibration energy transmitted to the material to be processed. The high-frequency vibration makes the hardware material produce high-frequency vibration inside when the ultrasonic wave is transmitted to the material. This vibration changes the microstructure of the material, enhancing its plasticity and fluidity. By reducing the yield strength of the material, the material is more easily deformed under external force.

[0045] In summary, through the arrangement of the material guiding mechanism 201 and the ultrasonic auxiliary stamping module, the material conveying and stamping process is more efficient, the non-processing time is reduced, and the rapid cooling system 4 and the ultrasonic auxiliary function effectively improve the forming precision of the hardware, reducing the quality problems caused by overheating. At the same time, the detachable design makes it more convenient to maintain and replace the material guiding mechanism 201 and other components, reducing downtime. Combined with the real-time monitoring of the detection system 5, timely feedback adjustment can be made to ensure that the entire stamping process is carried out in the best state, improving product consistency.
