[0056] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0057] like Figures 1 to 7 As shown, an embodiment of the present invention provides a stamping self-adhesive motor core precision mold, including a punch press 1, wherein the punch press 1 adopts a high-strength punch press frame 4 and a progressive die stamping structure for stamping materials, and the high-strength punch press frame 4 stabilizes the overall structure; the pressure limiting structures 2 on both sides assist the stamping structure in positioning the stamping of extremely thin materials, and a limiter 15 is used to give a certain pressure to the stamping material, so that the stamping material segment being stamped has better strength, so that when the punch press 1 stamps the extremely thin material, the pressure limiting structure 2 ensures that the stamping material segment being stamped is pulled straighter, and will not cause the strength of the material strip other than the stamping material segment being stamped to be too high, thereby causing fracture, and will not cause the overall strength fluctuation of the stamped extremely thin material strip to become larger, thereby making the stamping product smoother;

[0058] The pressure limiting structure 2 is arranged on the punching machine 1, and is used to adjust the position state and strength of the extremely thin material being punched. According to the actual needs on site, the length of the hydraulic rod 23 of the limiter 15 is changed to increase the pressure on the extremely thin material being punched, and the strength of the punching material section being punched is adjusted to prevent the extremely thin material from being fed, shifted, and broken during the punching process. Safety hazards. During use, the pressure limiting structure 2 divides the punching material section into two parts. The punching material section between the pressure limiting structure 2 is different from the punching material section outside. The space between the two pressure applying rods 22 in the limiter 15 of the pressure limiting structure 2 provides a buffer zone for these two different pressures, so that the material being punched is more straight, and there will be no feeding or shifting during punching; and the punching material section outside the pressure limiting structure 2 will not break or be excessively loose in the material transport structure 3.

[0059] The material transport structure 3 is used for material transportation and waste recycling, wherein the material transportation and waste recycling are operated at differential speeds. The operating speed of the driving motor is adjusted according to on-site needs so that the operating speeds of the driving motor of the feeding structure 24 and the driving motor of the pulling structure 25 are different, thereby generating a traction force between the two to improve the strength of the stamped ultra-thin material strip.

[0060] In the present invention, the punching machine 1 provides stability and safety of the overall structure. The force applied to the punched extremely thin material can be changed from a single adjustment to a linkage adjustment of multiple devices. The pressure limiting structure 2 can be changed according to the actual needs on site, and the adjustment is more convenient and accurate; the pressure limiting structure 2 is adjusted to drive the second motor 19 to adjust the distance between the transmission shaft 17 and the base bracket 16, and the first motor 18 is driven in linkage to adjust the height of the limiter 15, increase the pressure of the pressure rod 22, adjust the strength of the punched material, adjust the length of the hydraulic rod 23, compensate and increase the pressure of the pressure rod 22 on the punched extremely thin material, and more accurately adjust the strength of the punched extremely thin material. According to the actual needs on site, the running speed of the driving motor of the material transport structure 3 is adjusted to increase or decrease the traction force between the two on the punched extremely thin material, so as to increase or decrease the strength of the punched extremely thin material, so that the punched extremely thin material reaches an optimal punching state.

[0061] like Figures 1 to 7 As shown, the punch press 1 structure includes:

[0062] The punch frame 4 is used to provide pressure and support. The progressive die structure 5 is connected to the punch frame 4. According to actual on-site needs, the punch frame 4 cooperates with the progressive die structure 5. The punch frame 4 provides power for the progressive die structure 5, adjusts the stamping position, and enables the progressive die structure 5 to process the stamped ultra-thin material. At the same time, the stamped ultra-thin material belt is not broken, so that the pulling structure 25 can recycle waste well and prevent the stamped ultra-thin material from being fed up and deformed during operation.

[0063] The progressive die structure 5 is arranged in the punch frame 4 and is detachably connected to the punch frame 4 for punching and processing materials. According to the on-site requirements, it is connected with the feeding speed of the material transport structure 3 and the conveying speed of the punching material by the pressure limiting structure 2 to adjust the punching function speed so that the punching of extremely thin materials can work stably and the waste belt will not break after punching, and the intact pulled material structure 25 can be recovered.

[0064] In the present invention, the punch frame 4 and the progressive die structure 5 together constitute a processing and handling mechanism for punching extremely thin materials; according to the actual needs of the site, the structure of the die 6 and the punch 7 improves the processing operation of punching extremely thin materials, improves product accuracy, and increases the yield of good products.

[0065] like Figures 1 to 7 As shown, the progressive die structure 5 includes:

[0066] The die 6 is arranged in the punch frame 4, connected to the punch frame 4, and provided with a guide member 8. According to the actual needs on site, the punch 7 is cooperated with the punch to process the extremely thin material. One end of the spring is connected to the punch 7, and the other end is connected to the punch frame 4, so that the punch 7 can achieve elastic output without contacting the punch frame 4. At the same time, the guide member 8 and the limiting hole 9 are inserted into each other, which is convenient for the rapid positioning of the die 6 and the punch 7, and improves the processing accuracy of the extremely thin material, that is, the service life of the punch 7 is increased, and the waste generated during stamping will not adhere to the punch 7, resulting in reduced accuracy. The ejector oil cylinder 10 is arranged in the punch frame 4 and is plug-connected with the die 6. During the stamping process, it has an upward supporting force on the extremely thin material to prevent the extremely thin material from being supplied upward. At the same time, the supporting force of the ejector oil cylinder 10 can be adjusted according to actual on-site needs to improve the discharge of the product and prevent the material from being stuck. It is also easy to automate and realize automatic discharge, thereby improving the stamping process.

[0067] like Figures 1 to 7 As shown, the ejector cylinder 10 comprises:

[0068] The cylinder body 11 is arranged in the punch frame 4, and serves as the bottom support for the movement of the ejector cylinder 10. The cylinder column 12 is driven to telescope through the cylinder body 11, and the cylinder platform 13 moves along with the movement of the cylinder column 12. According to the on-site requirements, the rising height of the cylinder platform 13 is adjusted so that the cylinder platform 13 has an upward supporting force on the stamping material; according to the actual on-site requirements, the stamping speed of the progressive die structure 5 is coordinated to accurately provide supporting force for the stamping material, thereby increasing the discharge speed of the product and preventing material jamming or breakage of the stamping material belt.

[0069] like Figures 1 to 7As shown, the pressure limiting structure 2 includes:

[0070] The conveying structure 14 is arranged on the punch frame 4 and is slidably connected with the limiter 15. The second motor 19 drives the conveying shaft 17 to move forward and backward to extend or shorten the length of the stamped extremely thin material strip between the two limiting structures. In cooperation with the limiter 15, the rod sleeve 21 of the limiter 15 slides on the force bar 20 to limit the position of the stamped extremely thin material strip, increase the length of the hydraulic rod 23, increase the pressure of the pressure rod 22, and further increase the strength of the stamped extremely thin material strip. The first motor 18 drives the force bar 20 to move up and down to adjust the pressure of the force bar 20 on the pressure rod 22. According to the actual needs on site, the second motor 19 is driven to adjust the distance between the transmission shaft 17 and the base bracket 16 to increase or decrease the length of the stamped extremely thin material strip between the two limiting structures, control the length of the stamped extremely thin material strip, and improve the strength of the stamped extremely thin material strip. When the required strength of the stamped extremely thin material strip needs to be greater, the first motor 18 is required to drive the force bar 20 to move up and down to compensate for the pressure of the limiter 15 on the material, prevent the occurrence of arching, wrinkling or bending, and prevent the stamped material from loosening;

[0071] In the present invention, the pressure limiting structure 2 provides for adjusting the strength of the stamping material and limiting the position of the stamping ultra-thin material; the conveying structure 14 provides the punch frame 4 with a stable and appropriately conditioned stamping material; the pressure limiting structure 2 processes the stamping material to ensure that the stamping material conveyed into the progressive die structure 5 has a certain strength and an appropriately conditioned position. According to the actual needs on site, through the reasonable coordination of the conveying structure 14 and the limiter 15, the force applied to the stamping ultra-thin material can be adjusted from the single pressure of the limiter 15 to the joint pressure of the conveying structure 14 and the limiter 15, making the adjustment more convenient and accurate, and also convenient for adjustment; the second motor 19 is driven to adjust the distance between the transmission shaft 17 and the base bracket 16, to increase the stretching degree of the stamping material segment, and the first motor 18 is driven in linkage to adjust the lowering height of the limiter 15, to increase the pressure of the pressure rod 22 on the stamping material, to adjust the length of the hydraulic rod 23, and to further increase the pressure of the pressure rod 22 on the stamping ultra-thin material, so as to achieve the effect of adjusting the strength of the stamping material.

[0072] like Figures 1 to 7 As shown, the material transport structure 3 includes:

[0073] The feeding structure 24 includes a first driving motor 26 for feeding out materials. The feeding structure 24 is driven by the first driving motor 26, which can better control the feeding speed and prevent the problem of displacement of the stamping material during feeding.

[0074] The material pulling structure 25 includes a first drive motor 26 for recycling waste materials; the material pulling structure 25 includes a second drive motor 27 for recycling waste materials; the material pulling structure 25 is driven by the first drive motor 26, which can better control the material pulling speed and prevent the stamping material belt from breaking and loosening during the material pulling.

[0075] In the present invention, by adjusting the differential speed of the driving motors of the feeding structure 24 and the pulling structure 25 and utilizing the differential motion principle, the traction force caused by the differential speed is used to increase the strength of the extremely thin material being punched between the two, thereby preventing the material from being fed upward and deformed, controlling the position of the extremely thin material being punched to be less likely to change, and preventing the extremely thin material from being loosened and staying somewhere instead of moving forward with the strip, causing an accident.

[0076] like Figures 1 to 7 As shown, the feeding structure 24 includes:

[0077] The first drive motor 26 is arranged in the feeding structure 24 and is used to feed the material. The high-power torque of the first drive motor 26 can better provide power for the feeding structure 24, and the feeding structure 24 can stably transmit and punch extremely thin materials.

[0078] The material loading tray 28 is disposed in the feeding structure 24 and connected to the first driving motor 26. The material loading tray 28 of different sizes is used according to the on-site requirements, so as to better provide support and limit for the stamping material coil.

[0079] like Figures 1 to 7 As shown, the material pulling structure 25 includes:

[0080] The second drive motor 27 is arranged in the material pulling structure 25 to recycle materials; the second drive motor 27 is arranged in the material pulling structure 25 to recycle waste materials; the high-power torque of the second drive motor 27 is greater than that of the first drive motor 26, and can also better provide power for the material pulling structure 25. The recycling of waste materials requires more stable activities to ensure that the waste belt will not break or loosen during the pulling process; according to on-site requirements, different stamping materials have different operating torques to ensure that the material is not broken and the safety of the operator during use is guaranteed.

[0081] The material receiving tray 29 is disposed in the material pulling structure 25 and is rotationally connected to the second driving motor 27 .

[0082] In the present invention, by adjusting the differential speed of the first drive motor 26 and the second drive motor 27, the rotation speed of the second drive motor 27 is increased, the rotation speed of the first drive motor 26 is reduced, and the differential speed between the two is changed, so as to generate traction to straighten the stamped ultra-thin material, thereby increasing the strength of the stamped ultra-thin material between the two. According to the needs of the site, the reasonable use of the control loading tray 28 and the receiving tray 29 can further control the position of the stamped ultra-thin material, so that the position is not easy to change, the stamping manufacturing accuracy is improved, the operation cycle is shortened, and a certain cost is reduced.

[0083] The above is a preferred embodiment of the present invention.
