[0040] Please refer to Figures 1 to 3A U-tube aggregate machine includes a material receiving mechanism 100, a shaping mechanism 200, a material collecting mechanism 300 and a manipulator 400. The shaping mechanism 200 includes a shaping frame 210, a carrying platform 220 and a shaping mold 230 installed on the shaping frame 210. The material receiving mechanism 100 is used to receive and convey the U-tube 10 to the carrying platform 220. The carrying platform 220 is slidably installed on the shaping frame 210 to convey the pipe end 11 of the U-tube 10 to the shaping mold 230. The shaping mold 230 is used to shape the pipe end 11 of the U-tube 10. The manipulator 400 is used to convey the U-tube 10 from the carrying platform 220 to the material collecting mechanism 300.

[0041] In the U-tube aggregate machine provided by the present invention, the receiving mechanism 100 conveys the U-tube 10 to be shaped to the carrying platform 220. After receiving the U-tube 10, the carrying platform 220 slides to dock with the shaping mold 230 so that the shaping mold 230 can shape the tube end 11 of the U-tube 10. After the U-tube 10 is shaped, the carrying platform 220 slides away from the shaping mold 230, and then the robot 400 conveys the shaped U-tube 10 to the aggregate mechanism 300. The U-tube aggregate machine provided by the present invention can realize automatic loading, automatic processing, and automatic unloading, thereby improving the automation level and work efficiency of the shaping processing of the U-tube 10 and solving the technical problem that the existing shaping processing of the U-tube 10 requires manual loading and unloading.

[0042] The U-tube 10 is formed by bending a straight tube from the middle. The end of the U-tube 10 with a tube opening is called the tube opening end 11 (see Figure 11 ), the other end of the U tube 10 (i.e. the bending position) is called the tube tail end 12 (see Figure 5 ).

[0043] Specifically, the receiving mechanism 100 receives the U-tubes 10 output from the long U-tube machine. The shaping mechanism 200 shapes the U-tubes 10, and the collecting mechanism 300 collects the shaped U-tubes 10 to provide material for the next tube threading process. In the accompanying drawings, the receiving mechanism 100, shaping mechanism 200, collecting mechanism 300, and manipulator 400 process eight U-tubes 10 at a time. To facilitate visualization of the structure of the U-tube collecting machine, not all U-tubes 10 are shown. It should be understood that, in practice, the number of U-tubes 10 processed per batch is not limited to eight.

[0044] In some embodiments, please refer to Figure 4 、 Figure 5 、 Figure 8 and Figure 9The carrying platform 220 has multiple first clamping grooves 221 for clamping the U-tube 10. The material receiving mechanism 100 includes a material receiving bracket 110, a material receiving assembly 120 and a feeding assembly 130. The material receiving assembly 120 is installed on the material receiving bracket 110. The material receiving assembly 120 has multiple material receiving grooves 121. The distance between two adjacent material receiving grooves 121 is adjustable. The feeding assembly 130 has multiple feeding grooves 131 matching the multiple first clamping grooves 221. The feeding assembly 130 is slidably installed on the material receiving bracket 110 to transport the U-tube 10 from the material receiving assembly 120 to the carrying platform 220.

[0045] Because the spacing between the U-tubes 10 in the first and second steps differs, i.e., the spacing between adjacent U-tubes 10 received by the receiving mechanism 100 differs from the spacing required by the shaping mold 230, the multiple U-tubes 10 must be adjusted before they can be used for shaping. Specifically, the multiple receiving troughs 121 of the receiving assembly 120 receive the multiple U-tubes 10 in a one-to-one correspondence. The distance between adjacent receiving troughs 121 is adjustable, thereby adjusting the spacing between the U-tubes 10 to meet the spacing requirements of the shaping mold 230. The feeding assembly 130 slides to the receiving assembly 120, and the multiple U-tubes 10 with adjusted spacing are transferred from the receiving trough 121 of the receiving assembly 120 to the feeding trough 131 of the feeding assembly 130. Then, the feeding assembly 130 slides to the carrying platform 220, and the multiple U-tubes 10 with adjusted spacing are transferred from the feeding trough 131 of the feeding assembly 130 to the first clamping groove 221 of the carrying platform 220. The carrying platform 220 then slides to the shaping mold 230, which can directly shape the multiple U-tubes 10. In this way, the above-mentioned receiving mechanism 100 can achieve a smoother connection between U-tubes 10 between adjacent processes, effectively improving work efficiency.

[0046] In addition, the material receiving mechanism 100 includes a feeding assembly 130 for conveying the U-tube 10 to the carrying platform 220 and a material receiving assembly 120 for adjusting the spacing of the U-tube 10, so that the material receiving mechanism 100 can simultaneously adjust the spacing of the U-tube 10 and convey the U-tube 10, effectively improving work efficiency.

[0047] Specifically, the sliding direction of the feeding assembly 130 is perpendicular to the sliding direction of the carrying platform 220 .

[0048] Specifically, please refer to Figure 4 and Figure 5The feeding assembly 130 includes a first guide rail 132, a first slider 133, a support plate 134, and a plurality of first clamping blocks 135. The first guide rail 132 is mounted on the receiving bracket 110. The first slider 133 is slidably mounted on the first guide rail 132 and connected to the support plate 134. The feeding assembly 130 is slidably mounted on the receiving bracket 110 by means of the sliding fit between the first slider 133 and the first guide rail 132, facilitating the receiving of U-tubes 10 from the receiving assembly 120 and transporting them to the carrying platform 220. The plurality of first clamping blocks 135 are installed at intervals on the support plate 134, and a feeding trough 131 is formed between adjacent first clamping blocks 135. The plurality of first clamping blocks 135 are arranged on the support plate 134, forming a feeding trough 131 with the same spacing as the first clamping groove 221 of the carrying platform 220, facilitating the transport of U-tubes 10 from the feeding assembly 130 to the carrying platform 220.

[0049] Specifically, the first slider 133 is connected to the end of the support plate 134 away from the carrying platform 220. Although the first slider 133 slides on the first guide rail 132 installed on the material receiving bracket 110, the support plate 134 and the U-tube 10 located in the feeding trough 131 can slide onto the shaping mechanism 200 to transport the U-tube 10 to the carrying platform 220, so that the material receiving mechanism 100 and the shaping mechanism 200 can be independent of each other and the structures do not interfere with each other, and the support plate 134 can slide between the material receiving mechanism 100 and the shaping mechanism 200 to realize the transportation of the U-tube 10.

[0050] For further information, please refer to Figure 5 The feeding assembly 130 also includes a conveyor belt 136 rotatably mounted on the material receiving bracket 110. The conveying direction of the conveyor belt 136 is consistent with the sliding direction of the first slider 133. The top of the conveyor belt 136 supports the support plate 134 to avoid insufficient support of the support plate 134 by the first slider 133.

[0051] Optionally, refer to Figure 5 The conveyor belt 136 is wound between the two rotating wheels. The conveyor belt 136 is located above the first guide rail 132. The first slider 133 has a through hole for the conveyor belt 136 to pass through. The first slider 133 slides between the two rotating wheels. The two rotating wheels serve as a sliding limit for the first slider 133.

[0052] For further information, please refer to Figure 4 The carrying platform 220 is installed on the shaping frame 210 in a liftable manner. When the feeding assembly 130 slides to one side of the carrying platform 220, the carrying platform 220 rises to transport the U-tube 10 from the feeding assembly 130 to the carrying platform 220.

[0053] Among them, the carrying platform 220 and the feeding assembly 130 are staggered. When the feeding assembly 130 slides to the shaping frame 210, it is located on one side of the carrying platform 220, and the carrying platform 220 will not block the feeding assembly 130. Then, the carrying platform 220 rises and carries the suspended part of the U-tube 10. The U-tube 10 falls into the first clamping groove 221 of the carrying platform 220. The carrying platform 220 continues to rise, and the U-tube 10 is separated from the feeding groove 131 of the feeding assembly 130, thereby realizing the transportation of the U-tube 10 from the feeding assembly 130 to the carrying platform 220.

[0054] Similarly, the receiving assembly 120 is mounted on the receiving bracket 110 in a scalable manner, with the feeding assembly 130 located outside the receiving assembly 120. The receiving assembly 120 rises, receives the U-tubes 10, and adjusts the spacing between them. The feeding assembly 130 then slides to the side below the receiving assembly 120 and descends. The U-tubes 10, with their spacing adjusted, then descend into the feeding trough 131 of the feeding assembly 130.

[0055] Specifically, please refer to Figure 5 、 Figure 8 and Figure 9 The material receiving assembly 120 includes a receiving drive member 122, a second guide rail 123 and a plurality of material receiving parts 125. The receiving drive member 122 and the second guide rail 123 are both installed on the material receiving bracket 110. The material receiving part 125 has a material receiving groove 121. The material receiving part 125 is slidably installed on the second guide rail 123 through a second slider 126. The adjacent two material receiving parts 125 are slidably connected by a connecting rod 127. The receiving drive member 122 is connected to the first material receiving part 125 among the plurality of material receiving parts 125 to drive the first material receiving part 125 to slide along the second guide rail 123.

[0056] Among the plurality of material receiving portions 125 arranged in a row, any end of the plurality of material receiving portions 125 is defined as the head end of the plurality of material receiving portions 125, and correspondingly, the other end is defined as the head end of the plurality of material receiving portions 125. The material receiving portion 125 located at the head end of the plurality of material receiving portions 125 is defined as the first material receiving portion 125. For example, please refer to Figure 5 The ends of the multiple material receiving portions 125 that are away from the load-bearing platform are the head ends of the multiple material receiving portions 125, and correspondingly, the ends of the multiple material receiving portions 125 that are close to the load-bearing platform are the tail ends of the multiple material receiving portions 125. It is understood that in other embodiments, the ends of the multiple material receiving portions 125 that are away from the load-bearing platform may be the tail ends of the multiple material receiving portions 125, and the ends of the multiple material receiving portions 125 that are close to the load-bearing platform may be the head ends of the multiple material receiving portions 125.

[0057] The retracting drive 122 drives the first receiving portion 125 to slide. Since adjacent receiving portions 125 are slidably connected by a connecting rod 127, the multiple receiving portions 125 move in concert. If the first receiving portion 125 slides away from the last receiving portion 125, the multiple receiving portions 125 disperse, increasing the spacing between the multiple receiving portions 125 and the multiple receiving troughs 121. Conversely, the spacing between the multiple receiving portions 125 and the multiple receiving troughs 121 decreases. In this way, the receiving assembly 120, through the retracting drive 122 and connecting rod 127, achieves adjustable spacing between the receiving troughs 121.

[0058] It is understood that in other embodiments, the receiving drive member 122 is connected to the first receiving portion 125 of the plurality of receiving portions 125, and two adjacent receiving portions 125 are slidably connected via elastic members, and the receiving assembly 120 can also achieve adjustable spacing of the receiving troughs 121. Alternatively, each receiving portion 125 is equipped with a receiving drive member 122, and the receiving assembly 120 can also achieve adjustable spacing of the receiving troughs 121.

[0059] Optionally, the retracting drive member 122 is a cylinder or a motor.

[0060] For further information, please refer to Figure 8 and Figure 9 The material receiving assembly 120 further includes a retraction and expansion limiter 128 mounted on the material receiving bracket 110. The retraction and expansion limiter 128 is located at the rear end of the plurality of material receiving portions 125 to limit the material receiving portions 125 from sliding off the second guide rail 123. When the retraction drive member 122 retracts, the retraction and expansion limiter 128 blocks the last material receiving portion 125 from separating from the second guide rail 123, thereby keeping all the material receiving portions 125 on the second guide rail 123 and preventing them from sliding off the second guide rail 123.

[0061] For further information, please refer to Figure 8 and Figure 9 Each connecting rod 127 is provided with a sliding limit portion 124 at both ends, and the two adjacent material receiving portions 125 are slidably installed on the connecting rod 127 and are located between the two sliding limit portions 124, so that the two adjacent material receiving portions 125 can slide on the connecting rod 127 without sliding out of the connecting rod 127.

[0062] For further information, please refer to Figure 8 and Figure 9 The material receiving portion 125 includes a second clamping block 1251, a third clamping block 1252 and a bottom plate 1253. The second clamping block 1251 and the third clamping block 1252 are installed on the bottom plate 1253 at intervals, and a material receiving groove 121 is formed between the second clamping block 1251 and the third clamping block 1252.

[0063] Specifically, please refer to Figure 4The U-tube aggregate machine includes a base 140 and two receiving mechanisms 100, which are installed at intervals on the base 140. The receiving troughs 121 of the two receiving assemblies 120 and the feeding troughs 131 of the two feeding assemblies 130 are located at both ends of the U-tube 10, which can more stably support and transport the U-tube 10.

[0064] For further information, please refer to Figure 4 The two receiving mechanisms 100 are slidably mounted on the base 140 so that the distance between the two receiving mechanisms 100 is adjustable, thereby meeting the receiving and feeding of U-tubes 10 of different length specifications.

[0065] In one embodiment, please refer to Figure 4 and Figure 6 A plurality of fourth clamping blocks 222 arranged at intervals are provided on the carrying platform 220 , and two adjacent fourth clamping blocks 222 form a first clamping groove 221 .

[0066] Specifically, there are two groups of fourth clamping blocks 222 , one group is located at one end of the carrying platform 220 , and the other group is located at the other end of the carrying platform 220 . The two groups of fourth clamping blocks 222 clamp and fix the U-tube 10 together.

[0067] In one embodiment, please refer to Figure 4 and Figure 6 The shaping mechanism 200 also includes a platform driving component 223 installed on the shaping frame 210. The platform driving component 223 has a rotating output shaft 224. The setting direction of the rotating output shaft 224 is consistent with the sliding direction of the carrying platform 220. The carrying platform 220 is threadedly connected to the rotating output shaft 224, so that the platform driving component 223 drives the carrying platform 220 to slide through the rotating output shaft 224.

[0068] In one embodiment, please refer to Figure 4 and Figure 6 The shaping mechanism 200 also includes a clamping jaw 240 and a third guide rail 250 installed on the shaping frame 210. The clamping jaw 240 has a second clamping groove for clamping the tail end 12 of the U tube 10. The clamping jaw 240 is located on the side of the supporting platform 220 away from the shaping mold 230. The clamping jaw 240 and the supporting platform 220 are both slidably installed on the third guide rail 250.

[0069] After the U-tube 10 is transported to the carrier platform 220, the clamping jaws 240 slide toward the carrier platform 220 and clamp the tail end 12 of the U-tube 10, securing the U-tube 10 and ensuring its stable position. The clamping jaws 240 and the carrier platform 220 then slide together along the third guide rail 250 toward the shaping mold 230, allowing the tube end 11 of the U-tube 10 to be shaped.

[0070] Specifically, please refer to Figure 4 and Figure 6 The shaping mechanism 200 includes a plurality of clamping jaws 240 , and the second clamping grooves of the clamping jaws 240 correspond one-to-one to the first clamping grooves 221 of the carrying platform 220 .

[0071] Specifically, please refer to Figure 4 and Figure 6 The shaping mechanism 200 further includes a claw driving member 241 for driving the clamping claws 240 to slide. One claw driving member 241 synchronously drives the plurality of clamping claws 240, so that the plurality of clamping claws 240 move synchronously and neatly.

[0072] Specifically, please refer to Figure 4 and Figure 6 The shaping mechanism 200 also includes an anti-warping component 260, which is located between the clamping claw 240 and the carrying platform 220. The anti-warping component 260 includes an anti-warping bracket 261, an upper pressure plate 262 and a lower pressure plate 263. The anti-warping bracket 261 is slidably installed on the third guide rail 250, and the upper pressure plate 262 and the lower pressure plate 263 can be installed on the anti-warping bracket 261 in a liftable manner.

[0073] In this way, the first clamping groove 221 of the supporting platform 220 clamps the middle part of the U-tube 10, and the anti-warping bracket 261 presses the U-tube 10 located between the clamping claw 240 and the supporting platform 220 up and down through the upper pressure plate 262 and the lower pressure plate 263 to prevent the U-tube 10 from warping and ensure the stability of the position of the U-tube 10 so that the clamping claw 240 can accurately clamp and fix the tail end 12 of the U-tube 10.

[0074] For further information, please refer to Figure 6 The anti-warping assembly 260 further includes an anti-warping driving member 264 for driving the upper pressing plate 262 and the lower pressing plate 263 to move up and down.

The upper pressure plate 262 and the lower pressure plate 263 are slidably installed on the anti-warping guide rod 265. The anti-warping guide rod 265 guides the lifting and lowering movement of the upper pressure plate 262 and the lower pressure plate 263.

[0076] In one embodiment, please refer to Figure 8 and Figure 11The shaping die 230 includes a necking die base 231 and an expanding die 232. The necking die base 231 has a machining hole 233. The expanding die 232 is installed in the machining hole 233. A machining gap 234 is formed between the expanding die 232 and the wall of the machining hole 233 to accommodate the tube end 11 of the U-tube 10. The tube end 11 of the U-tube 10 is shaped and extruded into the shape of the machining gap 234. The expanding die 232 is used to expand the tube end of the U-tube 10, and the necking die base 231 is used to shrink the tube end of the U-tube 10. The expanding die 232 controls the minimum diameter, while the necking die base 231 controls the maximum diameter.

[0077] In one embodiment, please refer to Figure 8 and Figure 10 The number of the shaping molds 230 is consistent with the number of the U-tubes 10 , so that the U-tubes 10 located in the first clamping grooves 221 of the carrying platform 220 are matched with the shaping molds 230 in a one-to-one correspondence.

[0078] Specifically, please refer to Figure 8 and Figure 10 The shaping mechanism 200 also includes a shaping driver 235. The shaping molds 230 are slidably mounted on the third guide rail 250. The shaping driver 235 is used to drive the multiple shaping molds 230 to slide synchronously, ensuring consistent shaping quality. The carrying platform 220 transports the U-tube 10 to the front of the shaping molds 230. The shaping driver 235 drives the shaping molds 230 to slide forward, squeezing the tube ends 11 of the U-tubes 10 to perform the shaping operation.

[0079] In one embodiment, please refer to Figure 2 、 Figure 8 and Figure 11 The shaping mechanism 200 also includes a clamping die 270 mounted on the shaping frame 210, positioned between the shaping die 230 and the supporting platform 220. This clamping die 270 clamps the center of the U-tube 10 within the first clamping groove 221 of the supporting platform 220. The clamping die 270 clamps the front end of the U-tube 10, exposing the tube end 11, allowing the shaping die 230 to perform the shaping process on the tube end 11. The clamping die 270 secures the U-tube 10, maintaining its stable position and improving the quality of the shaping process.

[0080] Specifically, please refer to Figure 2 、 Figure 8 and Figure 11 The clamping mold 270 includes an upper mold base 271, a lower mold base 272 and a clamping drive 273. The upper mold base 271 and the lower mold base 272 can be lifted and lowered on the shaping frame 210. The clamping drive 273 drives the upper mold base 271 and the lower mold base 272 to close to achieve the clamping of the U tube 10.

[0081] Specifically, please refer to Figure 2 、 Figure 8 and Figure 11 The shaping mechanism 200 also includes a tube handling assembly 280 located between the supporting platform 220 and the clamping die 270. The tube handling assembly 280 includes multiple tube handling components 281 and a tube handling driver 282. The tube handling components 281 are mounted on the shaping frame 210 in a traversable manner, and the tube handling driver 282 is used to drive the tube handling components 281 to move up and down. The tube handling components 281 are located above the supporting platform 220. The multiple tube handling components 281 are arranged in intervals to form guide grooves for the passage of the U-tubes 10. The tube handling components 281 are used to adjust the spacing between adjacent U-tubes 10 to facilitate the entry of the U-tubes 10 into the clamping die 270.

[0082] In one embodiment, please refer to Figure 1 、 Figure 3 and Figure 4 The U-tube collecting machine also includes a transfer table 500. The manipulator 400 includes a first manipulator 401 and a second manipulator 402. The first manipulator 401 is used to transfer the U-tube 10 from the carrying platform 220 to the transfer table 500, and the second manipulator 402 is used to transfer the U-tube 10 from the transfer table 500 to the collecting mechanism 300. The transfer table 500 is used to buffer the U-tubes 10 after shaping, so that the shaping mold 230 can continuously perform the shaping operation of the U-tube 10, thereby improving work efficiency.

[0083] Optionally, the structure of the transfer platform 500 is the same as that of the carrying platform 220 .

[0084] Specifically, please refer to Figure 1 、 Figure 3 and Figure 4 The U-tube aggregate machine also includes a fourth guide rail 600, which is installed on the shaping frame 210. The shaping mold 230, the transfer table 500 and the aggregate mechanism 300 are distributed in sequence along the setting direction of the fourth guide rail 600, and the first manipulator 401 and the second manipulator 402 are slidably installed on the fourth guide rail 600.

[0085] Specifically, please refer to Figure 3 and Figure 7 The first manipulator 401 has multiple third clamping slots for clamping the U-tubes 10, and the second manipulator 402 has multiple fourth clamping slots for clamping the U-tubes 10. The number of fourth clamping slots is different from the number of third clamping slots. In this way, the U-tubes 10 that have been shaped can be reordered on the transfer table 500.

[0086] For example, the shaping mold 230 processes eight U-tubes 10 at a time, and the collecting mechanism 300 can accommodate sixteen U-tubes 10 in one layer. The first manipulator 401 has eight third clamping slots, and the second manipulator 402 has sixteen fourth clamping slots. The U-tubes 10 are re-arranged into groups of sixteen on the transfer table 500 for the second manipulator 402 to grasp.

[0087] In one embodiment, please refer to Figure 3 and Figure 7 The manipulator 400 includes a mechanical support 410, a lifting drive member 420, a mounting base 430, a clamping drive assembly 440 and a clamping member 450. The mounting base 430 can be lifted and lowered on the mechanical support 410. The lifting drive member 420 is installed on the mechanical support 410. The lifting drive member 420 is used to drive the mounting base 430 to lift and lower. The bottom of the mounting base 430 has a plurality of receiving grooves 431 for accommodating U-tubes 10. The clamping member 450 corresponds to the receiving grooves 431 one by one. The clamping member 450 is movably installed in the receiving grooves 431. The clamping drive assembly 440 is installed on the mounting base 430. The clamping drive assembly 440 is connected to the clamping member 450 to drive the clamping member 450 to move to clamp the U-tube 10 fixed in the receiving groove 431.

[0088] First, the lifting drive 420 drives the mounting seat 430 to descend so that the receiving groove 431 at the bottom of the mounting seat 430 can be loaded into the U-tube 10. Second, the clamping drive assembly 440 drives the clamping member 450 to move in the receiving groove 431, so that the clamping member 450 can move to contact and clamp the U-tube 10 fixed in the receiving groove 431, thereby clamping the U-tube 10. Third, the lifting drive 420 drives the mounting seat 430 to rise, thereby transporting the U-tube 10. Fourth, the manipulator 400 arrives at the transfer table 500 or the collecting mechanism 300, the mounting seat 430 descends, and the clamping member 450 moves to release the U-tube 10, thereby completing the release of the U-tube 10.

[0089] Among them, the detailed structure of the manipulator can be found in the Chinese utility model patent with the invention name "A manipulator for clamping copper tubes" and patent number "20122041115208".

[0090] In this embodiment, the clamping member 450 is rotatably disposed through the mounting base 430. As the clamping member 450 rotates, the distance between the clamping member 450 and the walls of the receiving groove 431 changes. As the distance between the clamping member 450 and the walls of the receiving groove 431 gradually decreases, the U-tube 10 can be clamped. As the distance between the clamping member 450 and the walls of the receiving groove 431 gradually increases, the U-tube 10 can be released.

[0091] In one embodiment, please refer to Figure 4The material collection mechanism 300 includes a material collection bracket 310 and a plurality of material needles 320 spaced apart on the bracket 310. Adjacent material needles 320 are spaced at a predetermined distance from each other, forming a storage space for accommodating the U-tubes 10. The robot 400 neatly arranges the U-tubes 10 in the storage space. This allows for orderly picking during unloading, and can simultaneously pick up U-tubes 10 at the same height, ensuring not only orderly picking but also a large number of picks and high efficiency.

[0092] Please refer to Figure 4 The material collecting mechanism 300 also includes a material blocking plate 330, which is installed at one end of the material collecting bracket 310 to prevent the U-tube 10 from falling from the material collecting mechanism 300, and plays the role of leveling the two ends of the U-tube 10, so that the U-tube 10 can be placed more neatly and is conducive to unloading.

[0093] Please refer to Figure 4 The material collecting mechanism 300 further includes a roller 340 mounted on the bottom of the material collecting bracket 310. Specifically, the roller 340 includes two universal wheels and two fixed wheels, which can facilitate the staff to save effort and efficiently transport materials, thereby improving production efficiency.
