Description

Technical Field

[0001] The present invention relates to the technical field of aluminum hoses, and specifically relates to a forming device for aluminum hoses. Background Art

[0002] In people's daily life and production, various packaging materials are often used to encapsulate and store materials. Among them, the metal packaging material, the aluminum hose, is a common packaging material and is applicable to industries such as cosmetics and medicine.

[0003] Since conventional aluminum hoses have different shapes, stamping operations are required during processing. For example, the existing Chinese patent document CN202222581679.0 discloses a forming device for aluminum hoses, including a forming box, a rotating seat, a door body, a die base, a die core, a rotating mechanism, and a stamping mechanism. The bottom of the forming box is fixed on the rotating seat. There are two die bases on the left and right. A die core is arranged on the top of the die base. Through holes are opened at the bottom of the die base. A connecting frame is arranged at the bottom of the die base, and the top of the connecting frame is fixedly connected to each die base. One side of the inner top of the forming box is fixedly provided with a stamping box. Through the arranged rotating mechanism, the two die bases are intermittently placed at the bottom of the stamping box. Through the arranged stamping mechanism, the stamping block moves downward to stamp the die core, and the aluminum hose is stamped and formed between the die core and the die base. Cooperating with the rotating mechanism, the forming time of the aluminum hoses on the two die bases is shortened, and the working efficiency is improved. Although the forming device in the above solution can realize the sequential forming of aluminum hoses on two die bases, each stamping is only limited to forming two aluminum hoses. After the forming is completed, it is necessary to manually remove and replace new hoses to continue stamping. Therefore, during the process of mass stamping and forming of pipes, the efficiency is still insufficient. Although there are many existing ones that use robotic arms for automatic loading and unloading of aluminum hoses, the loading and unloading actions of the robotic arm during operation require the cooperation of power provided by multiple motors, making the entire loading and unloading process too complicated and the cost too high. Summary of the Invention

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figures 1 - 3 , a forming device for an aluminum hose shown in the figure, including an operating platform 1 for installing a forming die, and a lower pressing plate 2 for pressing and forming the aluminum hose on the forming die is provided directly above the operating platform 1. During operation, the aluminum hose is placed on the forming die, and then the hydraulic system drives the lower pressing plate 2 to move downward, so that the punching plate moves downward to punch the core of the forming die, and the aluminum hose is punched and formed in the core; It further includes: clamping units 3 provided on the left and right sides of the operation table 1 for clamping aluminum hoses. A rotating unit 4 is installed on one side of the clamping unit 3 for rotating the clamping unit 3 left and right; a triggering unit 5 fixed on the left and right sides of the lower pressing plate 2 for automatically causing the clamping unit 3 to loosen and clamp when the lower pressing plate 2 moves upward. After the stamping and forming is completed, the lower pressing plate 2 moves upward, driving the triggering unit 5 to move upward. The triggering unit 5 first transmits power to the clamping unit 3. One set of clamping units 3 clamps a new aluminum hose on the conveyor belt 6, while the other set of clamping units 3 just clamps the formed aluminum hose, ensuring the synchronization of the two actions until the upper end of the triggering unit 5 disengages from the clamping unit 3. Then the lower pressing plate 2 continues to move upward, thereby driving the rotating unit 4 to work. The rotating unit 4 drives the clamping unit 3 to rotate 180 degrees clockwise, so that one set of clamping units 3 rotates to directly above the forming die, and the other set of clamping units 3 rotates to the right side of the operation table 1 until the rotating unit 4 stops rotating. Then the lower pressing plate 2 continues to move upward, thereby driving the triggering unit 5 to transmit power to the clamping unit 3 again. At this time, the two sets of clamping units 3 generate a loosening action together, just putting the aluminum hose into the core of the forming die, and the formed hose is discharged. In this way, during the upward movement of the lower pressing plate 2, the aluminum hose is loaded and unloaded simultaneously. Compared with the existing method of manually removing and replacing a new hose to continue stamping, the loading and unloading operations can be completed during the stamping and forming process, improving the stamping and forming efficiency of the aluminum hose.

[0020] A conveyor belt 6 fixedly installed on one side of the operation table 1 is used for automatically conveying and loading the aluminum hoses. A transmission unit 7 is provided between one driving end of the conveyor belt 6 and the rotating unit 4. During the process of the rotating unit 4 driving the clamping unit 3 to rotate, the transmission unit 7 will also be driven to work together. The transmission unit 7 drives the conveyor belt 6 to convey the aluminum hoses, and conveys the new aluminum hoses to the position corresponding to the left clamping unit 3 again, thereby realizing the automatic conveying and loading operation. There is no need to drive the conveyor belt 6 to rotate by a motor, which can greatly simplify the complexity and cost of the equipment.

[0021] Further, referring to Figure 4 , the clamping unit 3 includes clamping blocks 301, connecting arms 302, a bidirectional lead screw 303 and a limiting member 304. There are two symmetrically arranged clamping blocks 301. One end of the connecting arm 302 is fixed to the clamping block 301, and the other end of the connecting arm 302 is threadedly connected to the bidirectional lead screw 303. Two one-way gears 305 are installed at both ends of the bidirectional lead screw 303, and the limiting member 304 is installed in the middle of the bidirectional lead screw 303.

[0022] Specifically, when clamping an aluminum hose, the trigger unit 5 drives the one-way gear 305 to rotate. The one-way gear 305 drives the bidirectional lead screw 303 to rotate, and the bidirectional lead screw 303 drives the two clamping blocks 301 to move closer to each other, thereby clamping and fixing the aluminum hose. Here, the one-way gear 305 is a structure that only allows one-way free rotation and reverse locking. Since the one-way gear 305 realizes one-way transmission through the cooperation of internal pawls (or rollers, wedges) and gear tooth grooves, which is an existing structure, its specific structure will not be described in detail.

[0023] Further, referring to Figure 5 , the limiting member 304 includes a bearing plate 3041, a connecting cylinder 3042, a fixing plate 3043 and a limiting rod 3044. Two bearing plates 3041 are symmetrically arranged in the middle of the bidirectional lead screw 303. The bearing plate 3041 is rotatably connected to the bidirectional lead screw 303 through a bearing. The two bearing plates 3041 are fixedly connected through the connecting cylinder 3042. The limiting rod 3044 is fixed to one side of the bearing plate 3041 through the fixing plate 3043. The connecting arm 302 is slidably sleeved on the limiting rod 3044. The bearing plate 3041 can perform bearing limit on the bidirectional lead screw 303, and the bearing plates 3041 are connected through the connecting cylinder 3042, which is equivalent to the bidirectional lead screw 303 being sleeved inside the connecting cylinder 3042. When the bidirectional lead screw 303 rotates, the connecting cylinder 3042 will not rotate, and the connecting cylinder 3042 will only drive the bearing plate 3041 to rotate. In this way, when performing a rotation action, the bidirectional lead screw 303 will only perform a revolution movement and will not perform a self-rotation movement, making the bidirectional lead screw 303 more stable during rotation.

[0024] Further, please refer to Figure 6 , the rotating unit 4 includes a U-shaped frame 401, a worm 402, a worm gear 403, a rotating shaft 404, a first gear 405, a second gear 406 and a third gear 407. One side of the U-shaped frame 401 is fixedly connected to the operating table 1 through a connecting plate. The two ends of the worm 402 are rotatably connected to the U-shaped frame 401 through bearings. The worm gear 403 is meshed with the worm 402. The rotating shaft 404 is fixedly connected to the middle hole of the worm gear 403. The first gear 405 is fixed to one end of the worm 402. The second gear 406 is fixed to the rotating shaft 404. Support plates are arranged on both sides of the second gear 406. The rotating shaft 404 is rotatably connected to the support plates through bearings. The third gear 407 is fixedly sleeved on the connecting cylinder 3042. A first rack 408 is fixed to the bottom of the lower pressing plate 2. The first rack 408 is meshed with the first gear 405.

[0025] Specifically, when the first rack 408 moves upward and meshes with the first gear 405, it will drive the first gear 405 to rotate. The first gear 405 drives the worm 402 to rotate, the worm 402 drives the worm wheel 403 to rotate, the worm wheel 403 drives the rotating shaft 404 to rotate, the rotating shaft 404 drives the second gear 406 to rotate, the second gear 406 drives the third gear 407 to rotate, and the third gear 407 drives the connecting cylinder 3042 to rotate, thereby driving the bearing plate 3041 to rotate. As a result, the bidirectional lead screw 303 connected to the bearing plate 3041 performs a revolution around the axis of the connecting cylinder 3042. Thus, before the first rack 408 and the first gear 405 disengage, the connecting arm 302 drives the clamping block 301 to just be able to rotate half a turn.

[0026] Furthermore, referring to Figure 7 , the trigger unit 5 includes a second rack 501 and a third rack 502. One side of the second rack 501 is fixedly connected to the lower pressing plate 2. The third rack 502 and the toothed side of the second rack 501 are arranged opposite to each other. A connecting frame 503 is fixed to the top of the second rack 501, and the bottom of the connecting frame 503 is fixedly connected to the third rack 502.

[0027] Specifically, first, during the upward movement of the lower pressing plate 2, the second rack 501 will first mesh with one of the one-way gears 305. Here, the one-way gear 305 will be locked. Thus, the second rack 501 drives the outer teeth of the one-way gear 305 to perform a revolution, driving the bidirectional lead screw 303 to rotate, enabling the clamping unit 3 to trigger a clamping action to clamp the aluminum hose. Then, during the upward movement of the lower pressing plate 2 driving the third rack 502, it will drive another one-way gear 305 to mesh. Here, the one-way gear 305 is also in a locked state. Since the second rack 501 and the third rack 502 are arranged face to face, the revolution directions of the two one-way gears 305 are exactly opposite, enabling the bidirectional lead screw 303 to reverse, thereby enabling the clamping unit 3 to perform a loosening action. During the downward movement of the lower pressing plate 2, the third rack 502 first meshes with one of the one-way gears 305. At this time, the one-way gear 305 is not in a locked state. Therefore, the third rack 502 will drive the one-way gear 305 to rotate self - rotatively, and the bidirectional lead screw 303 will not rotate. Similarly, when the lower pressing plate 2 moves downward to make the second rack 501 and the one-way gear 305 mesh, the bidirectional lead screw 303 will not rotate either. That is, when the lower pressing plate 2 moves downward, it will not perform a clamping and loosening action, but only make the first rack 408 and the first gear 405 mesh, driving the rotating unit 4 to rotate in the reverse direction, rotating the clamping unit 3 by 180 degrees to the corresponding position to prepare for the next action of clamping the aluminum hose.

[0028] Furthermore, please refer to Figure 6, one side of the bearing plate 3041 is provided with a first limiting ring 30411, and a first arc-shaped chute 30412 is further provided on the first limiting ring 30411. The radian size of the first arc-shaped chute 30412 is 180 degrees. One side of the bearing plate 3041 is fixed with a first limiting post 30413 adapted to the first arc-shaped chute 30412. The bottom of the first limiting ring 30411 is fixed to the operating table 1 through a connecting plate. When the third gear 407 drives the connecting cylinder 3042 to rotate, it will drive the bearing plate 3041 to rotate. The bearing plate 3041 drives the first limiting post 30413 to slide in the first arc-shaped chute 30412, so as to ensure that the connecting arm 302 is more stable during the revolution movement.

[0029] Further, please refer to Figure 9 , both sides of the limiting rod 3044 are provided with second limiting rings 30441, and a second arc-shaped chute 30442 is further provided on the second limiting rings 30441. The radian size of the second arc-shaped chute 30442 is 180 degrees. One end of the limiting rod 3044 is slidably sleeved with the second arc-shaped chute 30442. The bottom of the second limiting ring 30441 is fixed to the operating table 1 through a connecting plate. When the connecting arm 302 revolves, it will also drive the limiting rod 3044 to slide in the second arc-shaped chute 30442, so as to further improve the stability of the revolution movement of the material clamping unit 3.

[0030] Further, please refer to Figure 1 , both sides of the conveyor belt 6 are provided with mounting frames 601, and baffles 602 are fixed on the mounting frames 601. The aluminum hoses arranged on the conveyor belt 6 are located between the two baffles 602, so that the equally spaced aluminum hoses will not sway left and right when moving on the conveyor belt 6, ensuring the stability of the conveyor belt 6 for transporting the aluminum hoses, and also ensuring that the aluminum hoses can maintain a vertical state when entering the material clamping unit 3.

[0031] Further, please refer to Figure 1 , a blanking box 8 is provided on one side of the operating table 1 away from the conveyor belt 6. After the right material clamping unit 3 performs the loosening action, the formed aluminum hoses just fall into the blanking box 8, so as to realize the collection and storage of the aluminum hoses.

[0032] Embodiment 2: Please refer to Figure 3 and Figure 8 , this embodiment further explains Embodiment 1, and the difference is to optimize the conveyor belt 6.

[0033] Specifically, the transmission unit 7 includes a connecting shaft 701, a one-way pulley 702, and a transmission pulley 703. One end of the connecting shaft 701 is fixed to the rotating shaft 404. The one-way pulley 702 is connected to the connecting shaft 701 through a one-way clutch. The transmission pulley 703 is fixedly connected to a transmission roller of the conveyor belt 6. A belt is sleeved between the one-way pulley 702 and the transmission pulley 703.

[0034] Specifically, when the rotating shaft 404 rotates forward, that is, when the clamping unit 3 rotates from left to right, the one-way pulley 702 is in a locked state at this time and just drives the one-way pulley 702 to rotate. The one-way pulley 702 drives the transmission pulley 703 to rotate through the belt, and the transmission pulley 703 drives a transmission roller of the conveyor belt 6 to rotate, so that the conveyor belt 6 moves the next aluminum hose to the specified position. When the rotating shaft 404 rotates reversely, the one-way pulley 702 is in an unlocked state at this time, and the clutch inside the one-way pulley 702 rotates itself and does not drive the outer wheel body to rotate, so the belt does not drive the transmission pulley 703 to rotate, ensuring that the conveyor belt 6 does not perform the conveying work during the process of the clamping unit 3 rotating from right to left, and ensuring the rationality of the conveying movement of the aluminum hose.

[0035] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
