[0020] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] The embodiment of the present invention provides a FFC flat cable stamping and forming device, such as Figure 1-15 As shown, it includes: a stamping base 10 for supporting an FFC cable product 100, on which a stamping mechanism is installed; wherein the stamping base 10 includes a stamping substrate 11, on which two support seats 12 are relatively installed, and between the two support seats 12 is connected a support plate 13 for supporting the FFC cable, wherein one of the support seats 12 is arranged adjacent to the stamping mechanism.

[0024] The stamping mechanism includes a moving component 20, an alignment platform 30 and a stamping component 40 connected in sequence. The moving component 20 is used to drive the alignment platform 30 and the stamping component 40 to move in a direction close to or away from the FFC cable product 100, and the alignment platform 30 is used to adjust the position of the stamping component 40; in this embodiment, the moving component 20 includes a moving base 21 fixedly connected to the stamping substrate 11, and a moving plate 22 is slidably connected to the moving base 21. A moving cylinder 23 for driving the moving plate 22 to move is provided at one end of the moving base 21, and the moving plate 22 is connected to the alignment platform 30; the alignment platform 30 can realize position adjustment in the horizontal direction and can be rotated and adjusted in the vertical direction. The alignment platform 30 is a common structure in the field and will not be repeated here.

[0025] The punching assembly 40 includes a punching frame 41, a first punching cylinder 42 and a punching knife 43. The first punching cylinder 42 is installed on the top of the punching frame 41. The punching frame 41 is slidably connected with a first punching slide 44, and the first punching slide 44 is positioned and connected with a first punching template 45. The punching knife 43 is fixedly embedded in the first punching template 45. The punching frame 41 is connected with a second punching template 46 corresponding to the first punching template 45. The second punching template 46 is provided with a first avoidance hole 461 for accommodating the punching knife 43 to pass through. At least two guide posts 47 are installed between the first punching template 45 and the second punching template 46, one end of the guide post 47 is installed in the first punching template 45, and the other end of the guide post 47 is movably connected in the second punching template 46; the first punching cylinder 42 is used to drive the punching knife 43 to move up and down in the vertical direction, so that the punching knife 43 punches the FFC cable product 100. In this embodiment, the first punching template 45 is fixedly installed on the first punching slide plate 44 by a positioning pin.

[0026] It should be noted that the present invention provides a FFC flat cable stamping forming device and forming method, which specifically includes a stamping base 10, on which a stamping mechanism is installed; the stamping mechanism includes a moving assembly 20, an alignment platform 30 and a stamping assembly 40. Through the design of the alignment platform 30, the position of the stamping assembly 40 can be effectively adjusted, so that the stamping knife 43 can be accurately aligned with the FFC cable product 100 when applying pressure; through the setting of the guide column 47, it is ensured that the stamping knife 43 remains stable during the lifting process to achieve smooth stamping; the stamping knife 43 is driven by the first stamping cylinder 42 to perform lifting and lowering movements, and the stamping force and speed can be accurately controlled; reasonable cylinder configuration can effectively reduce the vibration during the stamping process, thereby improving the overall stability and reducing the probability of product burrs. A stable stamping process not only improves production efficiency, but also reduces the scrap rate in the production process and improves the overall economic benefits. Therefore, the present invention solves the technical problem of unstable FFC cable stamping process in the prior art.

[0027] like Figure 1 , Fig. 9 and Fig.10 As shown, a stripper plate 48 is provided between the first stamping template 45 and the second stamping template 46, and the stripper plate 48 is connected to the first stamping template 45 by a plurality of bolts 49; Among them, one end of the bolt 49 overlaps the first stamping template 45, and the other end of the bolt 49 is interference fit with the stripper plate 48. The stripper plate 48 is provided with a stripper hole 481 for accommodating the passage of the stamping knife 43, and one end of the stamping knife 43 is located in the stripper hole 481. In this embodiment, after the stripper plate 48 contacts the FFC cable product 100, the first stamping template 45 continues to move downward along the bolt 49. The stripper hole 481 provides a precise guide and passage path to ensure that the stamping knife 43 can pass smoothly without obstruction during the stamping process, and facilitates the discharge of waste. The existence of the stripper hole 481 avoids direct contact between the stamping knife 43 and the stripper plate 48, reduces the wear of the stamping knife 43, and extends its service life.

[0028] It should be noted that the stripper plate 48 is located between the first stamping template 45 and the second stamping template 46, and plays a supporting and stabilizing role. During the stamping process, the stripper plate 48 can effectively withstand the impact force, disperse the pressure, and ensure the stable movement of the stamping knife 43. When the stamping knife 43 moves downward to complete the stamping action, the stripper plate 48 can help separate the stamped FFC cable product 100 from the stamping knife 43 to prevent the material from adhering to the stamping knife 43 and affecting the subsequent processing operations.

[0029] like Figure 1 , Fig. 9 and Fig.10As shown, a first receiving groove 451 is provided at the bottom of the first stamping template 45, and a second receiving groove 482 corresponding to the first receiving groove 451 is provided on the stripping plate 48; The guide column 47 is provided with a buffer spring 410, one end of which abuts against the first receiving groove 451, and the other end of which abuts against the second receiving groove 482. In this embodiment, after the punching knife 43 passes through the FFC cable product 100, the buffer spring 410 can reduce the impact force during the punching process, reduce the risk of damage to the product, and improve the quality of the finished product. The setting of the buffer spring 410 slows down and controls the end movement of the punching, thereby more accurately controlling the punching depth and ensuring that the FFC cable product 100 maintains consistency and high quality standards during the molding process.

[0030] It should be noted that when the stamping action occurs, the stamping knife 43 moves downward through the first stamping template 45 and contacts the FFC cable product 100. Since the high-frequency impact force may have a greater impact on the stamping assembly 40, the setting of the buffer spring 410 provides effective shock absorption and buffering. The buffer spring 410 can absorb the impact force and alleviate the impact on the equipment, thereby protecting other components of the stamping assembly 40 and extending its service life. After the stamping is completed, the reaction force of the buffer spring 410 helps to smoothly release the stamping force, thereby avoiding deformation or damage of the FFC cable product 100 due to excessive stamping force.

[0031] In summary, the stripper plate 48 and the embedded buffer spring 410 between the first stamping template 45 and the second stamping template 46 provide an efficient shock absorption and guiding stability solution. This design not only improves the durability and stability of the equipment and ensures the efficient operation of the stamping operation, but also ensures the molding quality of the FFC cable product 100, and has significant practical application effects and technical advantages.

[0032] like Figure 1 , Fig. 9 and Fig.10 As shown, a second stamping cylinder 420 is installed in the stamping frame 41, and a second stamping slide 430 corresponding to the first stamping slide 44 is slidably connected in the stamping frame 41; in this embodiment, the second stamping cylinder 420 provides support force to the second stamping template 46 to prevent the second stamping template 46 from being damaged due to excessive pressure from the stamping knife 43.

[0033] The second punching template 46 is positioned and installed on the second punching slide plate 430, and the second punching slide plate 430 is provided with a second avoidance hole 431 corresponding to the first avoidance hole 461, and the telescopic rod of the second punching cylinder 420 is connected to the second punching slide plate 430. In this embodiment, the first avoidance hole 461 and the second avoidance hole 431 are provided to facilitate the punching knife 43 to pass smoothly.

[0034] It should be noted that the second stamping slide 430 is driven to move by the second stamping cylinder 420, which ensures that during the stamping process, the second stamping cylinder 420 can drive the second stamping slide 430 and the second stamping template 46 to move coaxially and achieve precise matching with the first stamping template 45, thereby enhancing the stability and consistency of the stamping process and achieving a more precise stamping effect. The dual-cylinder motion system can realize a single or linkage operation mode according to actual needs, can be flexibly adjusted according to the design requirements of different products, adapt to the needs of various complex processes, and enhance the diversity and scope of application of the equipment.

[0035] like Figure 1-11 As shown, at least one contact component 50 is provided on the stripping plate 48, and the contact component 50 is used to elastically contact the FFC cable product 100; in this embodiment, the contact component 50 is an elastic contact structure, and under the drive of the first punching cylinder 42, the contact component 50 first contacts the FFC cable product 100 to provide an initial small-force contact. This elastic contact can buffer and reduce the instantaneous punching force, and gradually apply force, which can greatly reduce the instantaneous impact on the product and avoid damage to the product. During the contact process, the contact component 50 will apply uniform pressure to the FFC cable product 100, so that the pressure is evenly distributed on the product surface before the punching knife 43 acts, effectively reducing the local deformation caused by concentrated force.

[0036] Among them, under the drive of the first stamping cylinder 42, the contact component 50, the stripper plate 48 and the stamping knife 43 contact the FFC cable product 100 on the second stamping template 46 in sequence. In this embodiment, the contact component 50, the stripper plate 48 and the stamping knife 43 work in sequence, and through multi-step layer-by-layer unloading and protection, a continuous and reliable stamping process can be formed, reducing the intermediate adjustment and calibration time, thereby improving the overall production efficiency. In each step of the contact and stamping process, the contact component 50 plays a positioning and stabilizing role, ensuring that each stamping action is completed under precise positioning, thereby improving the processing accuracy. The contact component 50 plays a role of buffering and vibration reduction during the stamping process, which not only protects the product, but also reduces the wear of the stamping knife 43, the mold and other components on the stamping equipment, thereby extending the service life of the equipment. Due to the smoothness and balance of each stamping operation, the overall load distribution of the equipment is more reasonable, which effectively reduces the need for frequent overhaul and maintenance and improves the equipment utilization rate.

[0037] It should be noted that, driven by the first stamping cylinder 42, the contact assembly 50 first makes elastic contact with the FFC cable product 100 to mitigate the initial contact impact. As the stamping stroke continues, the stripper plate 48 then contacts the FFC cable product 100 to further stabilize the product position and prepare for the final stamping operation. Finally, the stamping knife 43, when fully positioned and stable, passes through the stripper hole 481 of the stripper plate 48 to complete the stamping operation of the FFC cable product 100. This ensures that each step of the operation is very precise and orderly, and ultimately forms a high-quality product.

[0038] In summary, the contact assembly 50 is arranged on the stripper plate 48, and the contact assembly 50 provides elastic buffering and protection through a multi-step, layer-by-layer stamping process, ensuring that the FFC cable product 100 remains stable and evenly stressed during the stamping process to avoid damage, thereby maximizing the molding quality and production efficiency of the product, while effectively extending the service life of the equipment and reducing maintenance costs. The technical effect of this design is remarkable, ensuring high efficiency, safety and high quality standards in industrial processing.

[0039] like Figure 11-15 As shown, a third receiving groove 483 is provided in the stripping plate 48, and the contact assembly 50 includes a contact spring 51 installed in the third receiving groove 483; in this embodiment, the provision of the third receiving groove 483 facilitates the installation of the contact spring 51.

[0040] Among them, the stripper plate 48 is provided with a mounting column 484 located in the third receiving groove 483, the mounting column 484 and the stripper plate 48 are an integrally formed structure, and the contact spring 51 is sleeved on the mounting column 484; one end of the contact spring 51 is fixedly connected to the stripper plate 48, and the other end of the contact spring 51 is fixedly connected to a contact pressure block 52, and a contact rubber pad 53 for flexible contact with the FFC cable product 100 is bonded and fixed to the contact pressure block 52. In this embodiment, the contact rubber pad 53 and the contact pressure block 52 are both cylindrically arranged; the height of the stripper plate 48 in the vertical direction is higher than the height of the contact rubber pad 53. The guiding effect of the mounting column 484 ensures that the movement path of the contact spring 51 and the contact pressure block 52 is accurate, and poor contact caused by deflection is avoided. Since the mounting column 484 and the stripper plate 48 are an integrally formed structure, the stability of the structure is further improved, and the risk of loose components caused by mechanical vibration or frequent use is reduced.

[0041] It should be noted that the contact rubber pad 53 is soft and has a certain resilience. When the contact rubber pad 53 contacts the FFC cable product 100, it can effectively protect the product surface and avoid scratches, deformation or other mechanical damage caused by hard contact. The cylindrical design of the contact rubber pad 53 further optimizes the force distribution, so that the contact force is evenly transmitted and the risk of local high pressure is reduced. The contact spring 51 absorbs and alleviates the instantaneous impact force during the stamping process through elastic deformation, reduces the direct impact on the FFC cable product 100, and extends the service life of the equipment. Through the elastic design of the contact spring 51, the contact component 50 is allowed to automatically adjust the force under different stamping conditions to adapt to the slight height differences on the product surface.

[0042] It should also be noted that the structural design is compact, and the cooperation between the stripper plate 48, the mounting column 484 and the contact component 50 realizes an efficient step-by-step contact process, reducing the friction of the direct contact between the punching knife 43 and the FFC cable product 100. During the stamping process, the contact component 50 first contacts the FFC cable product 100, and achieves preliminary positioning and buffering through flexible contact, ensuring that the product remains stable in subsequent stamping links and reducing dislocation and processing errors. Under the protection of the contact rubber pad 53, the product surface is intact and the yield rate is significantly improved. It has a reasonable structure and complete functions, which can significantly improve the molding quality of the FFC cable product 100, while reducing the maintenance cost of the equipment. It is suitable for production scenarios with high requirements for product surface quality and stamping accuracy.

[0043] like Fig.13 and Fig.14 As shown, a limiting protrusion 521 is provided on the side wall of the contact pressure block 52, and a limiting rod 54 is passed through the stripping plate 48; in this embodiment, the limiting protrusion 521 and the contact pressure block 52 are an integrally formed structure, and the limiting rod 54 limits the contact pressure block 52 to prevent the contact pressure block 52 from extending outward under the elastic force of the contact spring 51.

[0044] The limiting rod 54 includes a limiting portion 541, a threaded portion 542 and a rotating portion 543 which are connected in sequence and are an integrally formed structure. The limiting portion 541 is used to limit the limiting protrusion 521, and the threaded portion 542 is threadedly connected to the stripping plate 48. In this embodiment, the stripping plate 48 is sequentially provided with a first groove 486 and a second groove 487. The inner wall of the first groove 486 is a smooth surface and is connected to the third receiving groove 483. The first groove 486 is used to accommodate the limiting portion 541 passing through. The second groove 487 is threadedly matched with the threaded portion 542. The inner diameter of the first groove 486 is smaller than the inner diameter of the second groove 487.

[0045] It should be noted that when the limiting rod 54 is away from the limiting protrusion 521, the contact pressure block 52 can freely extend and retract in the third accommodating groove 483, and in a natural state, the contact pressure block 52 extends outward under the elastic force of the contact spring 51, thereby increasing the distance between the contact rubber pad 53 and the stripping plate 48, thereby increasing the buffering distance of the contact component 50 and further enhancing the buffering effect of the contact component 50.

[0046] like Fig.13 and Fig.14 As shown, a contact plane 5211 is provided on the limiting protrusion 521, and a limiting plane 5411 and a limiting arc surface 5412 connected to each other are provided on the limiting portion 541; in this embodiment, the number of the limiting planes 5411 and the limiting arc surface 5412 can be set to multiple, so that the contact pressure block 52 can be limited at different positions of the third accommodating groove 483.

[0047] The limiting plane 5411 and the limiting arc surface 5412 are both used to contact the contact plane 5211, and the rotating part 543 is provided with a rotating plane 5431 corresponding to the limiting plane 5411. In this embodiment, the limiting rod 54 has three working states. In the first working state, the limiting plane 5411 of the limiting rod 54 contacts the contact plane 5211; in the second working state, the limiting arc surface 5412 of the limiting rod 54 contacts the contact plane 5211; in the third working state, the limiting rod 54 does not contact the limiting protrusion 521. Since the rotating plane 5431 corresponds to the limit, the plane state of the limiting plane 5411 of the limiting part 541 can be obtained by observing the plane state of the rotating plane 5431 of the rotating part 543, which is convenient for users to quickly perceive and adjust. The three working states of the limiting rod 54 enable the operator to adjust according to different stamping requirements, reducing the trouble of frequent adjustment of equipment due to process changes. By rotating the limit rod 54 or adjusting the working state, the user can flexibly switch the working mode according to different processing requirements, thereby improving production efficiency.

[0048] It should be noted that, under different working conditions, the contact block 52 can be precisely adjusted according to specific process requirements, so that the system can adapt to various stamping depths, pressures and operating requirements. By switching different working states, the equipment can be quickly adjusted according to product specifications or stamping requirements during operation, greatly improving the flexibility and adaptability of the production process. Through the design of the limiting plane 5411 and the limiting arc surface 5412, a variety of positioning methods are provided for the contact block 52. The limiting cooperation of the contact plane 5211 and the limiting plane 5411 ensures the stability of the contact block 52 and avoids unnecessary movement and position deviation. The limiting arc surface 5412 provides more flexibility and adjustability in the second working state, ensuring that the block can move freely within a certain range to adapt to the height differences of the products and changes in the stamping process.

[0049] In summary, through the ingenious design of the limiting protrusion 521, the limiting part 541, and the rotating part 543, combined with various working states, the positioning and supporting functions of the contact block 52 are significantly enhanced. This structure gives the equipment a high degree of flexibility and precision, enabling it to adapt to different stamping requirements and providing a more stable and adjustable stamping process. This structure not only improves the stamping accuracy and product quality, but also reduces the wear and maintenance costs of the equipment, and improves the overall production efficiency and service life of the equipment.

[0050] like Figure 11-15 As shown, the stripper plate 48 is provided with a slide groove 485 which is connected with the third receiving groove 483, and the side wall of the contact pressure block 52 is provided with a hemispherical groove 522, and a ball 55 is embedded in the hemispherical groove 522, and the ball 55 is in contact with the slide groove 485. In this embodiment, the slide groove 485 is connected with the first groove 486; when the contact pressure block 52 is pressed, the contact spring 51 is squeezed, and the ball 55 rolls in the slide groove 485 until the contact rubber pad 53 enters the third receiving groove 483; at this time, the ball 55 does not contact the notch of the first groove 486. In this embodiment, through the provision of the ball 55, the traditional sliding friction is changed into rolling friction, which significantly reduces the friction resistance between the moving parts, and ensures that the contact pressure block 52 is smoother and more stable during the movement.

[0051] It should be noted that when the contact pressure block 52 begins to be subjected to force, the contact spring 51 is compressed, and at the same time the ball 55 remains stable in the hemispherical groove 522; as the pressure increases, the contact pressure block 52 continues to compress the contact spring 51, and the ball 55 rolls in the slide groove 485 to maintain the smooth movement of the contact pressure block 52; the contact rubber pad 53 gradually enters the third accommodating groove 483, and after the stripping plate 48 contacts the second stamping template 46, the contact rubber pad 53 flexibly contacts the FFC cable product 100, and the contact spring 51 is not further compressed; at this time, the ball 55 does not contact the notch of the first groove 486, ensuring smooth and accurate positioning.

[0052] In summary, by adding the slide groove 485 and the ball 55 design between the stripper plate 48 and the contact block 52, the structure effectively ensures the stable and smooth movement of the contact block 52 during the stamping process, while reducing friction and wear, and improving the reliability and production efficiency of the equipment. This structure not only achieves higher precision and stability, but also enhances the service life of the equipment and the molding quality of the product, and has significant industrial application value.

[0053] like Figure 1 , Figure 5 and Figure 6As shown, a first detection assembly 60 is provided on the stamping substrate 11 and is arranged adjacent to the stamping mechanism; wherein the first detection assembly 60 includes a first detection seat 61 arranged in a frame structure, a first detection camera 62, a first crimping cylinder 63 and a crimping block 64 are installed on the first detection seat 61, a first installation groove 641 is provided at the bottom of the crimping block 64, and a first rubber pad 65 for contacting the FFC cable product 100 is fixedly installed in the first installation groove 641; The first crimping cylinder 63 is used to drive the crimping block 64 to move up and down in the vertical direction, so that the first rubber pad 65 is close to or away from the FFC cable product 100; the first detection camera 62 is used to perform visual inspection on the FFC cable product 100 on the stamping base 10. In this embodiment, the position, state and quality of the FFC cable product 100 can be monitored in real time by capturing image data with the camera to ensure that the state of the product before stamping meets the requirements. The vertical height of the first detection camera 62 is higher than the vertical height of the stamping mechanism.

[0054] It should be noted that the equipment can be kept in a stable operating state through the coordinated work of the first detection assembly 60, the first crimping cylinder 63 and the crimping block 64. The first crimping cylinder 63 can accurately adjust each action in the crimping process, avoiding over-crimping or uneven crimping, and improving the safety of the equipment.

[0055] like Figure 1 , Figure 5 and Figure 6 As shown, the first detection component 60 also includes a first linear electric cylinder 66 arranged opposite to the first detection seat 61, and a first mounting seat 67 is slidably connected to the first linear electric cylinder 66. The first mounting seat 67 is equipped with a first light source 68 for providing illumination to the first detection camera 62.

[0056] It should be noted that the first mounting seat 67 is driven to move by the first linear electric cylinder 66, so that the first light source 68 provides light to the first inspection camera 62; after the first inspection is performed relative to the visual inspection of the FFC cable product 100, the first linear electric cylinder 66 drives the first mounting seat 67 to return to its original position, so as to facilitate the subsequent stamping operation of the stamping mechanism and avoid motion interference between the two.

[0057] like Figure 1-3 As shown, the stamping substrate 11 is provided with a second detection component 70 arranged side by side with the stamping mechanism. The second detection component 70 includes a second detection seat 71, on which a second detection camera 72 and a second crimping cylinder 73 are installed; in this embodiment, the second detection seat 71 is arranged adjacent to another support seat 12.

[0058] Among them, a crimping frame 74 is connected to the telescopic rod of the second crimping cylinder 73, and the crimping frame 74 is connected to a second rubber pad 75 for crimping the FFC cable product 100 after stamping, and the second detection camera 72 is used to detect the size of the FFC cable product 100 after stamping. In this embodiment, a detection through hole 741 is provided in the crimping frame 74, and a second mounting groove 742 is provided at the bottom of the crimping frame 74, and the second rubber pad 75 is fixedly installed in the second mounting groove 742. The second detection camera 72 performs dimensional detection on the stamped product to ensure that each link of the product after stamping can meet the design specifications and avoid quality problems such as dimensional over-tolerance. The first detection component 60 is mainly responsible for the detection before stamping, while the second detection component 70 is responsible for the detection after stamping. Through multiple detections, the consistency and quality of the finished product are improved, and the rework and scrap rate are reduced. The stamped FFC cable product 100 is moved by an external moving structure, and it is moved to the second detection component 70 for detection.

[0059] It should be noted that the first crimping cylinder 63 drives the crimping frame 74 to move up and down in the vertical direction, which can drive the second rubber pad 75 to approach the FFC cable product 100, so that the second detection component 70 can perform size detection on the FFC cable product 100 after stamping.

[0060] It should also be noted that the detection targets of the first detection component 60 and the second detection component 70 can be interchanged. The first detection component 60 can detect the FFC cable product 100 after stamping, and the second detection component 70 can detect the FFC cable product 100 before stamping.

[0061] like Figure 1-3 As shown, a second light source 76 for providing light to the second detection camera 72 is installed on the second detection seat 71, and the second detection camera 72, the second light source 76 and the crimping frame 74 are all located on the same straight line. It should be noted that the second light source 76 makes the imaging of the second detection camera 72 clearer.

[0062] The present invention discloses a FFC flat cable stamping forming method, which is applied to the above-mentioned FFC flat cable stamping forming device, such as Fig.16 As shown, including: Step S1, placing the FFC cable product 100 on the stamping base 10; Step S2, according to the punching parameters of the FFC cable product 100, the stamping component 40 is moved to the punching position by the moving component 20, and the alignment platform 30 adjusts the position of the stamping component 40 so that the FFC cable product 100 is positioned and placed on the second punching template 46; in this embodiment, the punching parameters include the punching width and the number of punching times; Step S3, the first stamping plate 45 is driven by the first stamping cylinder 42 to move toward the second stamping plate 46 along the guide column 47, so that the stamping knife 43 moves downward in the vertical direction, and the stamping knife 43 stamps the FFC cable product 100 on the second stamping plate 46. In this embodiment, the second stamping cylinder 420 provides support force to the second stamping plate 46 to prevent the second stamping plate 46 from being damaged due to excessive impact force of the stamping knife 43.

[0063] It should be noted that the present invention realizes high-precision stamping and forming of the FFC flat cable product 100 through precise operating steps and efficient device design. The method ensures the quality and forming accuracy of the product, improves production efficiency, simplifies the operation process, and has a high degree of automation and flexibility, and can adapt to the processing requirements of products of various specifications, making the method have significant advantages and broad application prospects in industrial applications.
