Description

Technical Field

[0001] This invention relates to the field of stamping technology, and in particular to a stamping machine for the production and processing of aluminum-plastic composite caps. Background Technology

[0002] In the production and processing of aluminum-plastic composite caps, the stamping machine is the core equipment for forming the cap body. However, the stamping machines currently on the market used for the production of aluminum-plastic composite caps generally have many problems.

[0003] Among them, the stamping structure design is unreasonable, and the fit between the stamping rod and the cutting parts is low. When stamping and circumferential cutting are carried out simultaneously, irregular edges of the cover and poor forming accuracy are likely to occur, making it difficult to meet the strict requirements of aluminum-plastic composite covers for sealing performance and appearance quality.

[0004] Secondly, the lack of an effective shock absorption and buffer mechanism during the stamping process means that the stamping force is directly transmitted to the main body of the equipment, which not only generates significant vibration and noise but also exacerbates the wear of equipment components and shortens the service life of the equipment. In addition, the vibration may also cause the aluminum and plastic materials to shift during processing, further affecting the product qualification rate.

[0005] Furthermore, the inadequate unloading and waste disposal mechanisms make it difficult for the stamped aluminum-plastic composite covers to be quickly and smoothly discharged from the stamping station. Waste accumulation also easily causes equipment jamming, requiring frequent manual cleaning and severely reducing production efficiency. Additionally, the lack of a stable material conveying and precise positioning structure leads to unstable conveying and positional deviations of the aluminum-plastic raw materials before they enter the stamping station, resulting in uneven stress on the materials during stamping and consequently producing defective products. At the same time, insufficient pre-cutting precision of the raw materials makes it difficult to match the dimensional requirements of subsequent stamping processes, further affecting production continuity and product consistency.

[0006] These problems severely restrict the production quality and efficiency of aluminum-plastic composite covers, making it impossible to meet the needs of modern mass production. Therefore, a stamping machine with optimized structure and stable performance for the production and processing of aluminum-plastic composite covers is needed to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a stamping machine for the production and processing of aluminum-plastic composite caps, so as to solve the problems mentioned in the background art.

[0012] Preferably, a servo motor is fixedly installed on the front and rear edges of the left side of the base, and a first rotating shaft is fixedly installed on the output shaft of the servo motor. A second rotating shaft and a third rotating shaft are rotatably installed on the left and right sides of the inner side of the upper frame, respectively. A fourth rotating shaft is rotatably installed on the left side of the base. A conveyor belt is rotatably installed on the outer circumferential surface of the first, second, and third rotating shafts.

[0013] Preferably, a grid is fixedly installed on both sides of the left side of the upper frame, a mounting bracket is fixedly installed on the left side of the upper frame, a second telescopic rod is fixedly installed on the inner side of both the front and rear mounting brackets, a cutting blade is fixedly installed on the telescopic rods of both the front and rear second telescopic rods, and a stress roller is rotatably installed on the right edge of the upper frame.

[0014] Preferably, a first motor in a symmetrical configuration is fixedly installed on the upper inner surface of the housing, and a first gear is fixedly installed on the output shaft of each of the first motors. A first drive gear is installed by the common meshing of the two first gears on the left and right sides, and a first threaded sleeve is fixedly installed from the upper end face to the lower end face of the first drive gear.

[0016] Preferably, a limit ring is provided on the outer circumferential surface of the lower end of the movable screw, a guide rod is slidably installed from the upper end face to the lower end face of the limit ring, and a buffer pad ring is fixedly installed on the upper end face of the limit ring and outside the guide rod.

[0017] Preferably, a fixing ring is fixedly installed on the outer circumferential surface of the guide rod and at the lower end of the housing, and an air spring shock absorber is evenly fixedly installed in a ring array on the lower end face of the fixing ring.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention effectively solves the problems of low stamping accuracy and high vibration and noise in traditional equipment by optimizing the structure of the stamping assembly. The outer shell of the stamping assembly is fixed to the upper end of the inner side of the upper frame. The stamping rod installed inside can achieve precise stamping and forming of the cover. The lower end of the movable screw installed on the outer side of the stamping rod is fixed with a ring cutter, which can complete the ring cutting of the cover during stamping, ensuring that the edge of the cover is neat. It realizes the integrated operation of stamping and cutting, eliminating the need for subsequent position correction process. At the same time, the mounting ring on the outer side of the lower end of the movable screw is equipped with a ring array of guide rods. The lower end of the guide rod is fixed with a shock-absorbing ring. Air spring shock absorbers are also provided between adjacent shock-absorbing rings, which can efficiently absorb the impact force during the stamping process, reduce equipment vibration and noise, improve the forming accuracy of the aluminum-plastic composite cover, effectively buffer the stamping force, reduce the wear of equipment parts, extend the service life, and avoid material displacement caused by vibration.

[0019] 2. This invention solves the problems of poor unloading and waste accumulation in traditional equipment by improving the base structure and unloading mechanism. A waste frame is set on the left side of the base to directly receive the waste generated during stamping, preventing waste accumulation from affecting equipment operation. An arc-shaped sliding plate is fixed in the finished product groove opened from the upper end face of the base to the inside, and the rear end face of the base to the inside of the finished product groove is in a through-slope state. After stamping, the aluminum-plastic composite cover can quickly fall into the finished product groove through the finished product unloading hole in the center of the base, and be smoothly discharged along the inclined channel through the arc-shaped sliding plate, realizing automated unloading of finished products. At the same time, the sliding grooves on the left and right sides of the finished product groove are equipped with return springs and sliders. The sliders are connected to the base, and the telescopic cylinder inside the left side of the base drives the inclined block to move, which can push the base to slide smoothly up and down. This not only assists in the efficient unloading of finished products, but also supports and positions the raw materials during stamping, greatly reducing manual cleaning and intervention, and significantly improving production efficiency.

[0020] 3. This invention solves the problems of unstable raw material feeding, insufficient pre-cutting accuracy, and burrs on materials after stamping by constructing a multi-component collaborative material conveying, positioning, and pre-cutting system. The servo motor and multiple rotating shafts drive the conveyor belt to feed materials smoothly, the second telescopic rod drives the cutting blade to achieve precise pre-cutting of raw materials, and the telescopic cylinder drives the support platform and the conveyor belt to achieve bidirectional limiting. The whole process control ensures stable raw material feeding, accurate positioning, and dimensional compliance, avoids uneven stamping force, reduces the defect rate, improves raw material utilization, and ensures the stability of mass production and product consistency.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 11 The present invention provides a technical solution: A stamping machine for producing aluminum-plastic composite caps includes a scrap frame 1. Each corner of the lower end face of the scrap frame 1 is rotatably equipped with casters for moving the frame, ensuring that during operation, the scrap material can be transferred simply by pushing it without requiring manual handling. Figure 1 As shown.

[0026] Then, a base 2 is set on the right side of the waste frame 1. A finished product groove 201 is opened from the upper end face of the base 2 to its interior. An arc-shaped sliding plate 202 is fixedly installed inside the finished product groove 201. It should be noted that an inclined through groove is opened from the rear end face of the base 2 to the interior of the finished product groove 201. The through groove and the finished product groove 201 are in a through-hole state. Figure 4 As shown, during use, the finished products after stamping and cutting will enter the interior of the through slot along the arc-shaped slide plate 202, and then enter the next process through the through slot, saving manual material collection and saving manual operation time.

[0027] The finished product groove 201 has equally spaced sliding grooves 203 on its left and right sides. A return spring 204 is slidably installed inside each sliding groove 203. The lower end of the return spring 204 is fixedly installed at the center of the bottom surface inside the sliding groove 203. A slider 205 is fixedly installed on the top of the return spring 204, and the inner side of the slider 205 extends to the outer side of the sliding groove 203. Figure 4 As shown.

[0028] It should be noted that a shock-absorbing buffer rod can be added inside the return spring 204 to slow down the movement of the subsequent structure, ensuring that the subsequent structure will not slide up and down rapidly and significantly, but only allow the subsequent structure to move in a buffered manner, thus ensuring the safety of the structure.

[0029] A support platform 206 is fixedly installed between two adjacent sliders 205 on the left and right sides. A finished product unloading hole 207 is opened at the center position from the upper end face to the lower end face of the support platform 206.

[0030] Then, a telescopic cylinder 208 is fixedly installed inside the left side of the base 2, and a wedge 209 is fixedly installed on the telescopic rod of the telescopic cylinder 208, such as... Figure 5 As shown, the upper end face of the inclined block 209 and the lower end face of the support 206 are in a close fit.

[0031] Therefore, during use, when the telescopic cylinder 208 is activated, its telescopic rod will drive the inclined block 209 to move linearly. Since the upper end face of the inclined block 209 and the lower end face of the support platform 206 are in contact, the linear movement of the inclined block 209 is converted into the up-and-down movement of the support platform 206. Specifically, when the telescopic rod of the telescopic cylinder 208 extends, the inclined block 209 will move left and right. Because one side of the inclined block 209 is higher than the other, as the higher side contacts the lower end face of the support platform 206, it pushes the support platform 206 to move upward.

[0032] When the telescopic rod of the telescopic cylinder 208 retracts, the support platform 206 moves downward under the action of the return spring 204.

[0033] This design allows the support platform 206 to move smoothly up and down, enabling the finished product to be smoothly unloaded from the finished product unloading hole 207. Simultaneously, due to the addition of a shock-absorbing buffer rod inside the return spring 204, the support platform 206 will not experience rapid, large-amplitude sliding during movement, ensuring the safety and stability of the structure. After the top of the support platform 206 moves upward, its top will be in contact with the lower end face of the subsequent aluminum sheet, thus facilitating subsequent stamping and cutting operations.

[0034] Secondly, servo motors 3 are fixedly installed on the front and rear edges of the left side of the base 2. A first rotating shaft 301 is fixedly installed on the output shafts of both servo motors 3. Then, a U-shaped upper frame 4 is fixedly installed on the top of the base 2. A second rotating shaft 302 and a third rotating shaft 303 are rotatably installed on the lower inner side of the upper frame 4. A fourth rotating shaft 304 is rotatably installed on the upper left side of the base 2. Figure 3 As shown.

[0035] Therefore, conveyor tracks 305 are rotatably mounted on the outer circumferential surfaces of the first rotating shaft 301, the second rotating shaft 302, and the third rotating shaft 303, with the conveyor tracks 305 arranged in pairs, such as... Figure 3 As shown, the larger gap between the conveyor tracks 305 is used to allow the platform 206 to move up and down, such as... Figure 3 As shown, it should also be noted that the outer surface of the conveyor track 305 will be in contact with the outer circumferential surface of the fourth rotating shaft 304 to support and limit the conveyor track 305, preventing the conveyor track 305 from colliding with the upper left right angle of the base 2 and avoiding friction of the conveyor track 305. Figure 3 As shown.

[0036] Therefore, during use, when the servo motor 3 is started, its output shaft drives the first rotating shaft 301 to rotate. Since the conveyor belt 305 is rotatably mounted on the outer circumferential surface of the first rotating shaft 301, the second rotating shaft 302 and the third rotating shaft 303, the rotation of the first rotating shaft 301 will drive the conveyor belt 305 to start running.

[0037] The conveyor tracks 305 operate in pairs in an orderly manner. During operation, because the outer side of the conveyor track 305 is in contact with the outer circumferential surface of the fourth rotating shaft 304, the fourth rotating shaft 304 provides good support and limit for the conveyor track 305, enabling the conveyor track 305 to move smoothly along the predetermined trajectory without colliding with the right-angle position on the upper left side of the base 2. This effectively reduces the frictional wear of the conveyor track 305 and extends its service life.

[0038] Meanwhile, the gaps between the conveyor tracks 305 provide ample and suitable space for the up-and-down movement of the platform 206, ensuring that the platform 206 can smoothly move up and down to meet the needs of material transfer and processing operations during the production and processing of aluminum-plastic composite covers, ensuring that the entire stamping machine can operate efficiently and stably, and improving the production quality and efficiency of aluminum-plastic composite covers.

[0039] The upper frame 4 is fixedly installed with grids 401 on both the left and right sides. The grids 401 on the left and right sides can protect the staff and prevent splashing and injury.

[0040] Secondly, mounting brackets 402 are fixedly installed on the left side of the upper frame 4, near the front and rear edges. Second telescopic rods 403 are fixedly installed on the inner bottom surface of the mounting brackets 402. Cutting blades 404 are fixedly installed on the telescopic rods of both the front and rear second telescopic rods 403. Figure 11 As shown, a stress roller 405 is then rotatably mounted on the lower right end face of the upper frame 4, as follows. Figure 2 As shown, it should be noted that adjacent stress rollers 405 are provided with U-shaped rods, and the central axis of stress rollers 405 and the right end of the U-shaped rods are rotatably connected by the same shaft. The left sides of the U-shaped rods are all mounted on the circumferential surface of the same shaft, and both ends of this shaft are located at the lower right end of the upper frame 4. (It should be noted that since the raw material is continuously conveyed, the conveying speed may cause the roll to warp. Therefore, to avoid such situations, the two ends of the shaft connected to the left side of the U-shaped rods can use a drive device, such as a motor or a structure similar to a motor, to allow the stress rollers 405 to rotate at an angle.) The adjustment allows the stress roller 405 to smooth out any warping of the raw material. Furthermore, in conjunction with the aforementioned conveying device, it effectively prevents material accumulation. Additionally, during use, due to the conveying speed of the roll, the ends of the left-side rotating shaft can be made extendable, allowing the left-side rotating shaft to move with the U-shaped rod, which in turn moves the stress roller 405 synchronously, moving it away from or towards the base 2. Then, driven by the aforementioned motor, the stress roller 405 can be angled. However, it should be noted that this setting needs to be adjusted according to the actual site conditions.

[0041] With the above structure, during the operation, when the raw material after the stamping operation needs to be cut, the second telescopic rod 403 will extend according to the preset program, driving the cutting blade 404 to move downward and accurately cut the material. The cutting position and cutting force are precisely designed and adjusted to ensure the accuracy and quality of the cutting. After the cutting is completed, the second telescopic rod 403 will retract back to its original position.

[0042] The stress roller 405 rotates during operation as the equipment runs, applying a certain stress to the aluminum-plastic composite cover, making it flatter during transport and preventing bending or deformation. This ensures smooth subsequent processing and further improves the production quality and efficiency of the aluminum-plastic composite cover. This is because the aluminum sheet is in an unwinding state, and after being in a winding state for a long time, stress relief is required after unwinding to ensure the quality and pass rate of subsequent products.

[0043] A stamping assembly 5, matching the support platform 206, is fixedly installed on the upper inner surface of the upper frame 4. The stamping assembly 5 includes a housing 501. Symmetrically arranged first motors 502 are fixedly installed on the upper inner circumferential surface of the housing 501. First gears 503 are fixedly installed on the output shafts of the first motors 502. First threaded sleeves 505 are provided inside the two first gears 503. First drive gears 504 are fixedly installed on the outer circumferential surface of the first threaded sleeves 505. The first drive gears 504 and the first gears 503 are in a meshing state. It should be noted that a support plate is provided on the lower end surface of the first drive gear 504, i.e., on the inner circumferential surface of the housing 501, to support the first drive gear 504 at a fixed height, ensuring that the first threaded sleeves 505 are at a fixed height. Figure 8 As shown.

[0044] Then, a stamping rod 506 is slidably installed on the upper end face to the lower end face of the first threaded sleeve 505 and extending to the outer side of the outer shell 501. It should be noted that in order to ensure that the first threaded sleeve 505 rotates while the stamping rod 506 can only move up and down, a guide structure is provided at the contact part between the side wall of the stamping rod 506 and the first threaded sleeve 505. The guide structure is a combination of a guide groove and a guide block. The guide groove is opened on the inner side of the first threaded sleeve 505 in the vertical direction. The guide block is fixedly installed on the side wall of the stamping rod 506 and slidably disposed in the guide groove. With this arrangement, when the first threaded sleeve 505 rotates under the drive of the first drive gear 504, due to the restriction of the guide structure, the stamping rod 506 can only move in the vertical direction defined by the guide structure and will not rotate with the first threaded sleeve 505.

[0045] Therefore, during use, when the first motor 502 is started, the output shaft of the first motor 502 drives the first gear 503 to rotate. Since the first drive gear 504 and the first gear 503 mesh with each other, the rotation of the first gear 503 will drive the first drive gear 504 to rotate, which in turn drives the first threaded sleeve 505 to rotate.

[0046] Because of the guide structure (the cooperation between the guide groove and the guide block) set at the contact part between the side wall of the stamping rod 506 and the first threaded sleeve 505, the stamping rod 506 will not rotate with the first threaded sleeve 505, but will move in a straight line along the up and down direction defined by the guide structure.

[0047] When the first threaded sleeve 505 rotates forward, the stamping rod 506 moves downward, which can stamp the aluminum sheet placed on the bearing 206.

[0048] When the first threaded sleeve 505 reverses, the stamping rod 506 moves upward and returns to its initial position so that the next stamping operation can be performed. This cycle is repeated to achieve continuous stamping production of aluminum-plastic composite covers.

[0049] Then, a movable screw 511 is slidably installed on the outer side of the stamping rod 506, and a second threaded sleeve 510 is provided on the outer side of the upper end of the movable screw 511. A second drive gear 509 is fixedly installed on the outer circumferential surface of the second threaded sleeve 510, and a symmetrical second motor 507 is fixedly installed on the inner middle circumferential surface of the housing 501. A second gear 508 is fixedly installed on the output shaft of the second motor 507. The second gear 508 and the second drive gear 509 mesh with each other. It should be noted that the internal structure of the second threaded sleeve 510 and the movable screw 511 is the same as that of the first threaded sleeve 505 and the stamping rod 506. Therefore, the movable screw 511 can only move up and down. A ring cutter 519 is fixedly installed at the lower end of the movable screw 511 for cutting the stamped aluminum cover. Figure 9 As shown.

[0050] Therefore, during use, when the second motor 507 is started, the output shaft of the second motor 507 drives the second gear 508 to rotate. Since the second gear 508 and the second drive gear 509 mesh with each other, the rotation of the second gear 508 will drive the second drive gear 509 to rotate, which in turn drives the second threaded sleeve 510 to rotate.

[0051] Because of the guide structure (also a combination of guide groove and guide block) set at the contact part between the side wall of the movable screw 511 and the second threaded sleeve 510, the movable screw 511 will not rotate with the second threaded sleeve 510, but will move in a straight line along the up and down direction defined by the guide structure.

[0052] When the second threaded sleeve 510 rotates forward, the moving screw 511 moves downward, driving the ring cutter 519 downward, which can cut the stamped aluminum cover.

[0053] When the second threaded sleeve 510 reverses, the moving screw 511 moves upward, driving the ring cutter 519 back to its initial position so that the next cutting operation can be performed. This cycle is repeated to achieve continuous cutting of the stamped aluminum cover.

[0054] It should be noted that a ring-shaped support plate is fixedly installed on the inner circumferential surface of the housing 501. The support plate is used to support the second drive gear 509 and to ensure that the second threaded sleeve 510 is at a fixed height.

[0055] Secondly, an installation ring 512 is fixedly installed on the outer circumferential surface of the middle part of the movable screw 511. Four guide rods 513 are evenly fixedly installed in a ring array on the lower end face of the installation ring 512. A limit ring 514 is fixedly installed on the lower circumferential surface inside the housing 501. The lower ends of the guide rods 513 all pass through the limit ring 514 and are slidably combined. A buffer pad ring 515 is fixedly installed on the upper end face of the limit ring 514 and outside the guide rods 513. Figure 10 As shown.

[0056] A fixing ring 516 is fixedly installed at the lower end of each of the four guide rods 513 and on the outer side of the housing 501. A damping ring 517 is fixedly installed at the lower end of each guide rod 513. An air spring damper 518 is fixedly installed on the lower end face of the fixing ring 516 between two adjacent guide rods 513. Figure 10 As shown.

[0057] Therefore, during operation, when the ring cutter 519 cuts downwards against the aluminum cover, the mounting ring 512 moves downwards along with the moving screw 511, thereby causing the guide rod 513 to slide within the limiting ring 514. At this time, the buffer ring 515 provides a certain buffering effect, reducing the direct impact between the mounting ring 512 and the limiting ring 514. Furthermore, the damping ring 517 and the air spring damper 518 effectively absorb and disperse the vibration energy generated during cutting, ensuring the stability of the entire stamping press during operation. The damping ring 517, through its elastic properties, deforms when the guide rod 513 is impacted, thereby consuming some of the vibration energy. The air spring damper 518 utilizes the compressed air inside to generate a reaction force when subjected to pressure, further offsetting and weakening the vibration, enabling the stamping press to remain stable when cutting the aluminum cover, improving cutting accuracy and product quality.

[0058] When the ring cutter 519 moves upward after the cutting is completed, the guide rod 513 slides upward within the limiting ring 514. The damping ring 517 and the air spring damper 518 can work together to absorb and disperse vibration energy, making the entire equipment more stable during operation, reducing noise caused by vibration and wear on equipment parts, and improving the service life of the equipment and the accuracy of cutting.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
