[0031] A copper needle K punching mechanism, as shown in the appendix Figures 1-4 includes:

[0032] A fixed seat 11, which is provided with a receiving cavity 111

[0033] A K punching assembly, which includes an upper K punching knife 12 and a lower K punching knife 13. The upper K punching knife 12 is strip-shaped, and the lower K punching knife 13 is sheet-shaped; or, the upper K punching knife 12 is sheet-shaped, and the lower K punching knife 13 is strip-shaped. Part of the K punching assembly is located outside, and part of the K punching assembly is located in the receiving cavity 111. Here, the strip shape specifically means that the K punching knife is a conventional setting, an entire strip structure. The sheet shape specifically means that the K punching knife is composed of a plurality of equally spaced blades, and adjacent two blades are independently arranged. The blade and the whole K punching assembly can be fixed by plugging or buckling, etc. It should be noted that the shape of the blade is not drawn in the attached drawings, but the groove for fixing the blade has been shown in the attached drawings

[0034] A force multiplying assembly 14, which is accommodated in the receiving cavity 111. The force multiplying assembly 14 is linked with the K punching assembly, and the force multiplying assembly 14 produces a force multiplying effect, that is, improves the punching impact force and the punching quality. For example, it can be a multi-link structure, or a lever structure, or other structures with magnification multiples

[0035] A first driving source 15, which is linked with the force multiplying assembly 14. Here, the first driving source 15 is fixedly connected to the fixed seat 11, and the first driving source 15 can be a cylinder, or an oil cylinder, or a motor, etc

[0036] First, the first driving source 15 acts to drive the force multiplying assembly 14 to work, and drives the upper K punching knife 12 to move through the force multiplying assembly 14, or drives the lower K punching knife 13 to move, so as to achieve a K punching effect. Secondly, through the sheet-shaped setting, when one of the blades is damaged, it can be repaired and replaced separately, without replacing the whole K punching knife, which can reduce the maintenance cost and improve the maintenance efficiency

[0037] Specifically, as shown in the appendix Figures 1-4As shown, the upper K-knife 12 is strip-shaped, and the lower K-knife 13 is sheet-shaped. The power multiplication component 14 is linked with the lower K-knife 13. The power multiplication component 14 and the lower K-knife 13 cooperate to form a vertically upward driving effect. In this embodiment, the first driving source 15 is located on the top surface of the fixed seat 11, the output end of the first driving source 15 is vertically upward, and the power multiplication component 14 connects the output end of the first driving source 15 and the lower K-knife 13, so that the lower K-knife 13 moves vertically upward. In addition, the power multiplication component 14 can also be linked with the upper K-knife 12.

[0038] Specifically, as shown in the appendix Figures 1-4 As shown, it further includes a first driving mechanism. The power multiplication component 14 includes a connecting block 16 linked with the first driving source 15 and a connecting rod 17. The connecting block 16 and the connecting rod 17 are movably connected, and the movable connection can be a hinge or other linkage methods. In this embodiment, the connecting block 16 is located in the lower region of the accommodating cavity 111, and the first driving source 15 is vertically downward and forms a linkage with the connecting block 16. The connecting rod 17 is horizontally arranged. One end of the connecting rod 17 cooperates with the connecting block 16, and the other end of the connecting rod 17 cooperates with the lower K-knife 13. The first driving mechanism includes a driving member 18, a first slider 19 and a first slide rail 20. The first slider 19 is connected to the fixed seat 11, the first slider 19 slides on the first slide rail 20, and the driving member 18 drives the fixed seat 11 to move relative to the K-knife assembly. Driven by the driving member 18, the fixed seat 11 slides on the first slide rail 20. Since the connecting block 16 and the connecting rod 17 are movably connected, at this time, the fixed seat 11 can move relative to the K-knife assembly, and the K-knife assembly can be exposed for easy replacement and maintenance.

[0039] Specifically, as shown in the appendix Figures 1-4 As shown, the driving member 18 is a handle. Through the setting of the handle, the structure is simpler and the effect of manual operation is better achieved. In addition, an electric method can also be adopted, such as a motor.

[0040] Specifically, as shown in the appendix Figures 1-4 As shown, the fixed seat 11 is fixed with a sensor 21, and the sensor 21 senses the position of the driving member 18. The setting of the sensor 21 forms the position detection of the fixed seat 11 to ensure that the driving member 18 rotates in place, and only then can the first driving source 15 work. When the sensor 21 detects that the driving member 18 has not rotated in place or the fixed seat 11 has not moved in place, the first driving source 15 cannot work at this time. In addition, an alarm device can also be used to generate an alarm. In this embodiment, the sensor 21 can be an infrared sensor or a photoelectric sensor, etc.

[0041] Specifically, the driving member 18 is provided with a wear-resistant groove 181. The wear-resistant groove 181 is used to cooperate with the operator's hand to form human-computer interaction, which conforms to ergonomics.

[0042] Specifically, as attached Figures 1-4 As shown, the connecting block 16 is provided with a groove 161, and the connecting rod 17 is provided with a bearing 171, and the bearing 171 slides relative to the groove 161. The groove 161 is open toward one side of the bearing 171, and the bearing 171 can be located in the groove 161, or can slide toward the outside of the groove 161. The setting of the bearing 171 realizes the linkage effect between the connecting rod 17 and the connecting block 16. When the bearing 171 is located in the groove 161, the connecting block 16 drives the connecting rod 17 to move, and when the fixed seat 11 moves, the bearing 171 will move toward the outside of the groove 161. It should be noted here that the bearing 171 will not completely detach from the groove 161. The sliding distance here can be adjusted according to the position where the K-punching component needs to be exposed, that is, after the bearing 171 slides, the K-punching component needs to be exposed for easy maintenance.

[0043] Specifically, the K-punching assembly includes a lower slider 22 , which is linked to the lower K-punching knife 13 , and the lower slider 22 is located on the rotation track of the connecting rod 17 .

[0044] Specifically, as attached Figures 1-4 As shown, the lower limit block 23 is also included. The lower limit block 23 cooperates with the lower slider 22 to form a first shaft cavity. The first shaft cavity contains a first shaft sleeve 24. The connecting rod 17 rotates in cooperation with the first shaft sleeve 24. The lower limit block 23 is provided to form a chamber effect. The first shaft sleeve 24 is fixed in the chamber to form a rotation effect with the connecting rod 17.

[0045] Specifically, as attached Figures 1-4 As shown, it also includes a fixed block 25, which is located in the accommodating cavity 111. The fixed block 25 is connected and fixed to the fixed seat 11, and the pin passes through the fixed block 25 and is rotatably connected to the connecting rod 17. The setting of the fixed block 25 forms a rotating fulcrum effect, which better realizes the amplification of force. The position where the fixed block 25 cooperates with the connecting rod 17 is located between the first rotating shaft sleeve 24 and the bearing 171. Here, the position of the fixed block 25 can be adjusted according to actual needs, so as to realize the adjustment of the force amplification multiple.
