Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a continuous stamping forming equipment for copper strip. Background Technology

[0002] The continuous stamping forming equipment for copper strip is a mechanical device specifically designed for stamping copper strip material through a continuous die. It can efficiently and accurately stamp copper strip material into various required shapes and sizes. This equipment is widely used in many fields such as electronics, electrical engineering, communications, automobiles, and construction to produce various copper parts and components.

[0003] In traditional continuous stamping forming equipment for copper strip, a strong stamping force is rapidly applied to the copper strip during the stamping operation, aiming to press it into a preset shape. However, during this process, the copper strip material may undergo local deformation or adhesion within the mold cavity, which may cause the copper strip to stick tightly to the surface of the lower mold, making it difficult to demold smoothly. This affects stamping efficiency, increases the workload of workers, and also affects the processing of subsequent copper strip products.

[0004] For example, if copper strip gets stuck inside the lower die, it will not only directly hinder the normal stamping process of subsequent copper strips, leading to a significant decrease in production efficiency, but may also cause irreversible damage to the die itself. Frequent die damage not only increases the cost of replacement and maintenance, but also seriously affects the stability and reliability of the production line. In addition, stuck copper strips often need to be cleaned manually, which not only increases labor intensity, but may also cause safety hazards due to improper operation. Utility Model Content

[0005] This utility model discloses a continuous stamping forming equipment for copper strip, which aims to solve the problem that in traditional continuous stamping forming equipment for copper strip, when a strong stamping force is rapidly applied to the copper strip to press it into a preset shape, the copper strip material may undergo local deformation or adhesion within the mold cavity. As a result, the copper strip may stick tightly to the surface of the lower mold, making it difficult to demold smoothly, which in turn affects stamping efficiency, increases the workload of workers, and also affects the technical problems of subsequent processing of copper strip products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A continuous stamping forming equipment for copper strip includes a fixed base, a stamping mechanism on the top outer wall of the fixed base, a crossbar on one outer wall of the fixed base, a feeding rack and a receiving rack at both ends of the crossbar, and a copper strip coil wound inside the feeding rack and the receiving rack. The equipment also includes: a limiting mechanism located between the feeding rack and the receiving rack; a cleaning mechanism fixedly connected to one outer wall of the fixed base; and a pushing mechanism located below the limiting mechanism. The pushing mechanism includes a lower die, a support platform on the bottom outer wall of the lower die, a mounting frame on one outer wall of the support platform, and a first electric telescopic rod on one inner wall of the mounting frame. Three first toothed plates are fixedly connected to the movable end of the first electric telescopic rod. Three gears and three limiting rails are provided inside the support platform. Second toothed plates are slidably connected to the inner walls of the limiting rails. The gears mesh with the first and second toothed plates. A top plate is provided at one end of the second toothed plate.

[0008] The above technical solution improves stamping efficiency, reduces manual intervention, lowers operational difficulty and cost, and prevents copper strip products from getting stuck inside the lower die, affecting subsequent copper strip stamping. Specifically, during use, the copper strip is unwound from the copper strip coil on the feeding rack, passes through a limiting mechanism to ensure the copper strip's stable position during the stamping process, and then the stamping mechanism begins to stamp the passing copper strip to form the required shape. After stamping is completed, the first electric telescopic rod is activated, and its movable end drives the three first toothed plates to move forward. When the first toothed plates move forward... During movement, the first toothed plate meshes with the gear, driving the gear to rotate in place. The rotation of the gear, in turn, causes the second toothed plate, which meshes with it, to slide within the limiting rail. Since the limiting rail is inclined, the second toothed plate generates an upward thrust during the sliding process, which in turn causes the top plate to rise. After the copper strip is stamped, it is easy to push the copper strip out of the lower mold through the top plate. During the stamping and pushing process, some waste or debris may be generated. After the top plate pushes out the copper strip product, the waste can be cleaned up in time by the cleaning mechanism, ensuring the continuous and stable operation of the equipment.

[0009] In a preferred embodiment, the limiting mechanism includes two mounting plates and several pressure rollers. The mounting plates are located on the top outer wall of the support platform. The top inner wall of the mounting plates is provided with several equally spaced limiting components. Each limiting component includes a fixed cylinder. The top inner wall of the fixed cylinder is provided with a return spring. The several pressure rollers are respectively located at one end of the several return springs and the bottom inner wall of the mounting plate.

[0010] In this solution, when the copper strip moves from the feeding rack to the receiving rack via the limiting mechanism, its top and bottom surfaces will contact the pressure roller. The upper pressure roller can compress the return spring upward according to the thickness of the copper strip, thereby allowing the copper strip to pass through. Due to the elasticity of the return spring, the pressure roller can quickly return to its original position after the copper strip passes through, preparing for the subsequent passage of copper strip.

[0011] In a preferred embodiment, the stamping mechanism includes a cylinder, a fixing frame is provided on one outer wall of the fixing seat, the cylinder is located on the bottom outer wall of the fixing frame, two mounting cylinders are provided on the top outer wall of the fixing frame, a pressure plate is fixedly connected to the piston end of the cylinder, an upper mold is provided on the bottom outer wall of the pressure plate, and two limiting rods are provided on the top outer wall of the pressure plate. One end of the limiting rod completely penetrates the fixing frame, and the other end of the limiting rod is slidably connected to the inner wall of the mounting cylinder.

[0012] In this design, before stamping begins, the cylinder is in a non-operating state, the pressure plate is at its highest position, and the limiting rod fully penetrates the fixed frame and slides against the inner wall of the mounting cylinder. At this time, a certain gap is maintained between the upper and lower dies to provide space for the insertion of the copper strip and for stamping preparation. When stamping is required, the cylinder starts to work, converting the energy of compressed air or gas into mechanical motion, driving the piston end to move downward. The movement of the piston end causes the pressure plate and the upper die to move downward together until the upper die contacts the lower die and presses the copper strip. During the stamping process, the limiting rod slides inside the mounting cylinder, playing a guiding and limiting role, ensuring that the movement path of the pressure plate and the upper die is accurate and stable.

[0013] As described above, a continuous stamping forming equipment for copper strip includes a fixed base, a stamping mechanism on the top outer wall of the fixed base, a crossbar on one outer wall of the fixed base, a feeding rack and a receiving rack at both ends of the crossbar, and copper strip coils wound inside the feeding rack and the receiving rack. The equipment also includes: a limiting mechanism located between the feeding rack and the receiving rack; a cleaning mechanism fixedly connected to one outer wall of the fixed base; and a pushing mechanism located below the limiting mechanism. The pushing mechanism includes a lower die, a support platform on the bottom outer wall of the lower die, an installation frame on one outer wall of the support platform, and a first electric telescopic rod on one inner wall of the installation frame. Three first toothed plates are fixedly connected to the movable end of the first electric telescopic rod. Three gears and three limiting rails are provided inside the support platform. A second toothed plate is slidably connected to the inner wall of the limiting rails. The gears mesh with the first and second toothed plates. A top plate is provided at one end of the second toothed plate. The copper strip continuous stamping forming equipment provided by this utility model can improve stamping efficiency, reduce manual intervention, reduce operation difficulty and cost, and avoid copper strip products getting stuck inside the lower mold, thus affecting the technical effect of subsequent copper strip product stamping.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] The copper strip continuous stamping forming equipment disclosed in this utility model is mainly used in traditional copper strip continuous stamping forming equipment. During the stamping operation, a strong stamping force is rapidly applied to the copper strip to press it into a preset shape. However, during this process, the copper strip material may undergo local deformation or adhesion in the mold cavity, so the copper strip may stick tightly to the surface of the lower mold, making it difficult to demold smoothly. This affects the stamping efficiency, increases the workload of workers, and also affects the processing of subsequent copper strip products.

[0022] Reference Figure 1 , Figure 3 and Figure 4 A continuous stamping forming equipment for copper strip includes a fixed base 1, a stamping mechanism on the top outer wall of the fixed base 1, a crossbar on one outer wall of the fixed base 1, and a feeding rack 2 and a receiving rack 8 at both ends of the crossbar. Copper strip coils 3 are wound inside the feeding rack 2 and the receiving rack 8. The equipment also includes: a limiting mechanism located between the feeding rack 2 and the receiving rack 8; a cleaning mechanism fixedly connected to one outer wall of the fixed base 1; and a pushing mechanism located below the limiting mechanism, the pushing mechanism including a lower die 22. The bottom outer wall of 22 is provided with a support platform 9. One side of the outer wall of the support platform 9 is provided with a mounting frame 11. One side of the inner wall of the mounting frame 11 is provided with a first electric telescopic rod 15. The movable end of the first electric telescopic rod 15 is fixedly connected with three first toothed plates 16. The inside of the support platform 9 is provided with three gears 17 and three limiting rails 18. The inner wall of the limiting rail 18 is slidably connected with a second toothed plate 19. The gears 17 mesh with the first toothed plates 16 and the second toothed plates 19. One end of the second toothed plate 19 is provided with a top plate 20.

[0023] It should be noted that the range of the discharge port is larger than that of the unloading port, and the shape of the top plate 20 is not specifically defined. It can be arbitrarily changed according to the shape inside the lower mold 22, which facilitates the rapid ejection of the copper strip product.

[0024] The support platform 9 has a hollow structure inside. The support platform 9, the mounting frame 11 and the lower mold 22 are connected. A connecting plate 25 is provided between two adjacent first toothed plates 16. This arrangement makes it easy for the other two first toothed plates 16 to move forward synchronously when the movable end of the first electric telescopic rod 15 extends to one side.

[0025] In the specific implementation process, the limiting rail 18 is set at an inclination, the top outer wall of the support platform 9 has three feeding ports, and the interior of the lower mold 22 has three discharge ports. The three feeding ports correspond to the three discharge ports. During the ejection process, the top plate 20 can be designed as a "V" shape or other shapes that distribute the ejection force evenly on the entire surface of the copper strip product, avoiding damage caused by excessive local pressure. The inclination of the limiting rail 18 is to provide an upward thrust for the second toothed plate 19 when the pushing mechanism is working. When the first electric telescopic rod 15 drives the first toothed plate 16 to move forward, the first toothed plate 16 meshes with the gear 17, thereby driving the gear 17 to rotate. Due to the inclination of the limiting rail 18, when the gear 17 rotates, the second toothed plate 19 that meshes with it will slide in the limiting rail 18 along the inclination direction. This design makes the second toothed plate 19 not only move forward during the sliding process, but also generate an upward component force. This upward component force acts on the stamped copper strip product through the top plate 20, ejecting it from the lower mold 22.

[0026] Specifically, in use, the copper strip is unwound from the copper strip roll 3 on the feeding rack 2, passes through a limiting mechanism to ensure the copper strip's position is stable during the stamping process, and then the stamping mechanism begins to stamp the copper strip to form the required shape. After stamping is completed, the first electric telescopic rod 15 is activated, and its movable end drives the three first toothed plates 16 to move forward. When the first toothed plates 16 move forward, since the first toothed plates 16 mesh with the gears 17, the gears 17 are driven to rotate in place. The rotation of the gears 17 then drives the second toothed plates 19, which mesh with them, to slide within the limiting rail 18. Since the limiting rail 18 is inclined, the second toothed plates 19 slide during the process. This generates an upward thrust, which in turn causes the top plate 20 to rise. After the copper strip is stamped, it is easier to push the copper strip out of the lower die 22 through the top plate 20. During the stamping and pushing process, some waste or debris may be generated. After the top plate 20 pushes out the copper strip product, the waste will fall into the three discharge ports on the top of the support table 9 along the three discharge ports inside the lower die 22. The cleaning mechanism then cleans up the waste or debris in time, ensuring the continuous and stable operation of the equipment. This device can improve stamping efficiency, reduce manual intervention, reduce operation difficulty and cost, and prevent the copper strip product from getting stuck inside the lower die 22, affecting the stamping of subsequent copper strip products.

[0027] Reference Figure 1 , Figure 2 and Figure 4In a preferred embodiment, the limiting mechanism includes two mounting plates 10 and several pressure rollers 14. The mounting plates 10 are located on the top outer wall of the support platform 9. The top inner wall of the mounting plates 10 is provided with several limiting components distributed at equal intervals. The limiting components include a fixed cylinder 12. The top inner wall of the fixed cylinder 12 is provided with a return spring 13. The several pressure rollers 14 are respectively located at one end of the several return springs 13 and the bottom inner wall of the mounting plates 10.

[0028] The mounting plate 10 has a concave structure with a central groove. This groove can be used to accommodate and fix limiting components such as the fixing cylinder 12, the return spring 13, and the pressure roller 14. This design allows the limiting components to be installed more stably on the mounting plate 10, reducing the risk of loosening or damage caused by vibration or impact.

[0029] Specifically, when the copper strip moves from the feeding rack 2 to the receiving rack 8 via the limiting mechanism, its top and bottom surfaces will contact the pressure roller 14. The upper pressure roller 14 can compress the return spring 13 upward according to the thickness of the copper strip, thereby allowing the copper strip to pass through. Due to the elasticity of the return spring 13, the pressure roller 14 can quickly return to its original position after the copper strip passes through, preparing for the subsequent passage of copper strips.

[0030] Reference Figure 1 In a preferred embodiment, the stamping mechanism includes a cylinder 7, a fixed frame is provided on one outer wall of the fixed seat 1, the cylinder 7 is located on the bottom outer wall of the fixed frame, two mounting cylinders 4 are provided on the top outer wall of the fixed frame, a pressure plate 6 is fixedly connected to the piston end of the cylinder 7, an upper mold is provided on the bottom outer wall of the pressure plate 6, and two limiting rods 5 are provided on the top outer wall of the pressure plate 6. One end of the limiting rod 5 completely penetrates the fixed frame, and the other end of the limiting rod 5 is slidably connected to the inner wall of the mounting cylinder 4.

[0031] The cylinder 7 is located between the two limit rods 5.

[0032] Specifically, before stamping begins, cylinder 7 is in a non-working state, and pressure plate 6 is in its highest position. At this time, a certain gap is maintained between the upper mold and the lower mold 22 to provide space for the copper strip to be inserted and for stamping preparation. When stamping is required, cylinder 7 starts to work, converting the energy of compressed air or gas into mechanical motion, driving the piston end to move downward. The movement of the piston end drives pressure plate 6 and upper mold to move downward together until the upper mold contacts and presses the copper strip against the lower mold 22. During the stamping process, the limiting rod 5 slides in the mounting cylinder 4, playing a guiding and limiting role, ensuring that the movement path of pressure plate 6 and upper mold is accurate and stable.

[0033] Reference Figure 1 , Figure 3 and Figure 5In a preferred embodiment, the cleaning mechanism includes a fixed frame 21. A second electric telescopic rod 23 is provided on the inner wall of one side of the fixed frame 21. A push plate 24 is fixedly connected to the movable end of the second electric telescopic rod 23. A discharge port is opened on one side of the fixed frame 21. In use, the movable end of the first electric telescopic rod 15 pushes the debris into the fixed frame 21. Then, the second electric telescopic rod 23 is activated, so that its movable end extends forward and pushes the push plate 24 forward. During the forward movement, the push plate 24 will contact the waste in the fixed frame 21 and push it towards the discharge port. As the push plate 24 continues to push, the waste is gradually squeezed out of the discharge port, completing the cleaning process.

[0034] Working principle: During use, the copper strip is unwound from the copper strip coil 3 on the feeding rack 2. After passing through the limiting mechanism, the copper strip is kept in a stable position during the stamping process. Then, the stamping mechanism begins to stamp the copper strip to form the required shape. After stamping is completed, the first electric telescopic rod 15 is activated, and its movable end drives the three first toothed plates 16 to move forward. When the first toothed plates 16 move forward, they mesh with the gears 17, thereby driving the gears 17 to rotate in place. The rotation of the gears 17 then drives the second toothed plate 19, which meshes with it, to rotate on the limiting rail 1. The inner sliding mechanism 8, due to the inclined setting of the limiting rail 18, generates an upward thrust during the sliding process of the second toothed plate 19, which in turn drives the top plate 20 to rise. After the copper strip is stamped, it is easy to push the copper strip out of the lower mold 22 through the top plate 20. During the stamping and pushing process, some waste or debris may be generated. After the top plate 20 pushes out the copper strip product, the waste will fall into the three discharge ports on the top of the support table 9 along the three discharge ports inside the lower mold 22. The cleaning mechanism then cleans up the waste or debris in time to ensure the continuous and stable operation of the equipment.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
