[0002] FFC flexible flat cable, also known as Flexible Flat Cable, can arbitrarily select the number of wires and the spacing, making the connection more convenient, greatly reducing the volume of electronic products, reducing production costs, and improving production efficiency. It is most suitable for use as a data transmission cable between moving parts and the main board, between PCB boards, and in miniaturized electrical equipment. During the processing of FFC flexible flat cables, it is necessary to punch cuts at its ends to facilitate the insertion of terminals.

[0003] Most of the existing punching methods of punching machines are to use a single punch to cut the multi-section FFC flexible flat cable one by one in sequence, and the overall processing efficiency is relatively low. A small number of punching machines use multiple punches for punching, but the spacing between each punch is relatively fixed, making it difficult to meet the processing requirements of flexible flat cables of various sizes. For this reason, we propose a punching machine for FFC flexible flat cables to solve the problems mentioned above. Content of the Utility Model

[0023] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0024] Referring to Figure 1 、 Figure 2 and Figure 4 As shown in the figure, a flanging machine for FFC flexible flat cable includes a workbench 1. Two brackets 2 are fixedly connected to the upper edge of the workbench 1. The upper ends of the brackets 2 are fixedly connected with a top plate 3. Two symmetrically distributed telescopic rods 4 are fixedly connected to the inner top end of the top plate 3. The other ends of the telescopic rods 4 are fixedly connected with a lifting plate 5. A hydraulic cylinder for driving the lifting plate 5 to lift is fixedly installed on the upper end of the top plate 3. Two first fixing plates 6 are fixedly connected to the lower end of the lifting plate 5. A fixed seat 7 is fixedly connected between the two first fixing plates 6. A T-shaped groove 8 is penetrated and opened in the middle of the upper end of the fixed seat 7. A plurality of slide blocks 9 are slidably connected in the T-shaped groove 8. The lower ends of the slide blocks 9 are fixedly connected with a connecting seat 11 through bolts 10. The lower end of the connecting seat 11 is fixedly connected with a punch 12.

[0025] Furthermore, the connecting seat 11 can be disassembled by rotating and removing the bolt 10, the number of punches 12 can be changed according to the usage requirements, and the detachable design is convenient for the maintenance of the punch 12.

[0026] Referring to Figure 2 and Figure 3 As shown in the figure, two symmetrically distributed chutes 13 are penetrated and opened on the front and rear sides of the upper end of the fixed seat 7 near the T-shaped groove 8. Fixed screws 14 are connected to the corresponding positions of the upper ends of the slide blocks 9 and the chutes 13. The fixed screws 14 are slidably connected inside the chutes 13. Rubber blocks 15 are slidably connected to the outer surfaces of the fixed screws 14. Nuts 16 are threadedly connected to the outer surfaces of the fixed screws 14 near the upper ends of the rubber blocks 15.

[0027] Further, by sliding the slider 9 along the T-shaped groove 8, the position of a single punch 12 can be adjusted, thereby changing the distance between two adjacent punches 12, and it can meet the processing requirements of wire harnesses of various sizes. After the punch 12 is adjusted to the appropriate position, rotate the nut 16 so that the nut 16 pushes the rubber block 15 to abut against the upper end of the fixed seat 7. The lower end of the rubber block 15 has strong friction, and the position of the slider 9 can be fixed by the friction between the rubber block 15 and the fixed seat 7.

[0028] Refer to Figure 5 As shown, a scale line 17 is provided on the front side of the fixed seat 7, and a pointer 18 pointing to the scale line 17 is provided at the corresponding position of the front side of the slider 9 and the punch 12.

[0029] Further, the pointer 18 corresponds to the position of the punch 12 one by one, and the difference between the scale lines 17 pointed to by two adjacent pointers 18 is the distance between two punches 12. The adjustment of the punch 12 can be made more accurate by the setting of the scale line 17 and the pointer 18.

[0030] Refer to Figure 1 and Figure 5 As shown, a placement table 19 is fixedly connected to the upper end of the workbench 1 inside the bracket 2. An adjustment groove 20 is opened at the front part of the upper end of the placement table 19. A bidirectional threaded rod 21 is rotatably connected inside the adjustment groove 20. A motor 22 for driving the bidirectional threaded rod 21 to rotate is fixedly installed at the right end of the placement table 19. Two symmetrically distributed limit plates 23 are threadedly connected to the outer surface of the bidirectional threaded rod 21, and a second fixing plate 24 is fixedly connected to the upper end of the limit plate 23.

[0031] Further, the limit plates 23 are used to limit both ends of the wire harness. By driving the bidirectional threaded rod 21 to rotate by the motor 22, the two limit plates 23 can be made to approach or move away from each other, thereby adjusting the distance between the two limit plates 23 to adapt to the fixation of wire harnesses of different sizes, and the limit plates 23 are located on the front side of the fixed seat 7 and will not affect the edge punching process.

[0032] A cylinder 25 is fixedly installed at the upper end of the second fixing plate 24. The output end of the cylinder 25 penetrates through the upper end of the second fixing plate 24 and is fixedly connected to a pressing plate 26.

[0033] Further, the cylinder 25 can drive the pressing plate 26 to press on the upper end of the wire harness to fix the wire harness and prevent the wire harness from shifting during edge punching.

[0034] Working principle: When this device is in use, first, install the required number of punches 12 at the lower end of the slider 9 through bolts 10. Then, adjust the distance between adjacent punches 12 by moving the slider 9. When the punches 12 are adjusted to the appropriate positions, rotate the nut 16 so that the nut 16 pushes the rubber block 15 to abut against the upper end of the fixed seat 7, thereby fixing the position of the slider 9. After that, place the end of the wire harness directly below the punch 12. Then, drive the bidirectional threaded rod 21 to rotate through the motor 22, so that the limiting plates 23 are close to both sides of the wire harness for limiting. At the same time, drive the pressing plate 26 to press on the upper end of the wire harness to fix the wire harness through the cylinder 25. Finally, drive the punch 12 to descend through the hydraulic cylinder to perform edge punching on the wire harness.

[0035] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
