Description

Technical Field

[0001] This invention relates to the field of copper tube processing equipment technology, specifically to a combined, waste-free short tube bending machine. Background Technology

[0002] Copper pipes, aluminum pipes, and steel pipes are important components of the pipe processing industry and represent its fastest-growing sector. They are primarily used in construction and real estate, refrigeration, marine engineering, shipbuilding, automotive, and power industries. Therefore, integrated pipe bending machines that combine waste-free material cutting, shaping, and bending play a crucial role in the manufacturing of copper, aluminum, and steel pipes. These machines are environmentally friendly and waste-free, meeting current national environmental protection requirements. They can replace traditional multi-process or multi-machine manual production, achieving automated production.

[0003] Existing pipe bending machines can complete a series of processes including straightening, cutting, shaping, and bending. After straightening, the pipe material on the tray is circumferentially cut. Following cutting, a mechanism separates the pipe segments, which are then collected by a vibratory feeder and systematically fed to a shaping mechanism for shaping. Finally, the shaped pipe segments are transferred to the bending device for bending. In other words, the current shaping mechanism receives the pipe segments via a vibratory feeder and then transports them systematically. Furthermore, the current processing flow is relatively tortuous, prolonging the material transport time and thus affecting work efficiency. Summary of the Invention

Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0048] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0049] See Figure 1 A combined waste-free short pipe bending machine includes a straightening device 1, a cutting device 2, a shaping device 3, a transfer device 4, and a bending device 5. The straightening device 1, the cutting device 2, the shaping device 3, and the bending device 5 are arranged sequentially along the X-axis. The transfer device 4 transfers the pipe section that has been shaped on the shaping device 3 to the bending device 5.

[0050] The straightening device 1, cutting device 2, shaping device 3, transfer device 4, and pipe bending device 5 constitute a pipe bending processing line. To increase the equipment's capacity, multiple pipe bending processing lines can be set up, arranged side by side. In this embodiment, there are two pipe bending processing lines.

[0051] In this embodiment, the straightening device 1 and the cutting device 2 are existing technologies, and will be briefly described below.

[0052] See Figure 2 The straightening device 1 includes a straightening mechanism 11 and a conveying mechanism 12. The straightening mechanism 11 is used to straighten the pipe material, and the conveying mechanism 12 is used to convey the pipe material.

[0053] The straightening mechanism 11 includes a straightening assembly 111, which comprises a straightening feed end 1111, a straightening wheel set 1112, and a straightening discharge end 1113, all three being arranged along the X-axis. The straightening feed end 1111 is connected to one end of the straightening wheel set 1112, and the other end of the straightening wheel set 1112 is connected to the straightening discharge end 1113. The tubular material on the tray enters the straightening wheel set 1112 from the straightening feed end 1111, undergoes straightening processing by the straightening wheel set 1112, and is then output from the straightening discharge end 1113. In this embodiment, there are four sets of straightening assemblies 111, arranged side by side.

[0054] The conveying mechanism 12 includes a conveying clamping assembly, a conveying clamping drive 121, a conveying clamping assembly 122, and a conveying moving drive 123. The conveying clamping assembly and the conveying clamping drive 121 are mounted on a conveying carrier 120, which is slidably mounted on a machine base 6 along the X-axis. The conveying moving drive 123 is mounted on the machine base 6. The conveying clamping assembly is connected to the output end of the conveying clamping drive 121; the conveying carrier 120 is connected to the output end of the conveying moving drive 123. Pipe material straightened by the straightening mechanism 11 passes through the conveying clamping assembly. The conveying clamping drive 121 drives the conveying clamping assembly 122 to open or close to release or clamp the pipe material. The conveying moving drive 123 drives the conveying carrier 120 to move the conveying clamping assembly and the conveying clamping drive 121 along the X-axis. In this embodiment, the number of transport clamping components is the same as the number of straightening components 111. The transport clamping components and straightening components 111 correspond one-to-one, that is, there are four sets of transport clamping components. Each pair of transport clamping components is transported by the same transport clamping drive 121 and driven by 122.

[0055] The cutting device 2 includes a fixing mechanism 21 and a cutting mechanism 22. The fixing mechanism 21 is used to fix the pipe material, and the cutting mechanism 22 is used to perform circumferential cutting on the pipe material.

[0056] The fixing mechanism 21 includes a fixing clamping assembly 211 and a fixing clamping drive 212. The fixing clamping assembly 211 and the fixing clamping drive 212 are mounted on the fixing support 210, and the output ends of the fixing clamping assembly 211 and the fixing clamping drive 212 are connected. The fixing support 210 is fixed on the machine base 6 along the X-axis. The tube material output by the conveying mechanism 12 passes through the fixing clamping assembly 211. The fixing clamping drive 212 drives the fixing clamping assembly 211 to open or close, thereby releasing or clamping the tube material. In this embodiment, the number of fixing clamping assemblies 211 is the same as the number of conveying clamping assemblies. The fixing clamping assemblies 211 and the conveying clamping assemblies correspond one-to-one, that is, there are four sets of fixing clamping assemblies 211, of which every two sets of fixing clamping assemblies 211 are driven by the same fixing clamping drive 212.

[0057] The cutting mechanism 22 includes a cutting assembly 221 and a cutting drive 222. The cutting assembly 221 is rotatably mounted on a cutting support 220, and the cutting drive 222 is mounted on the cutting support 220, which is mounted on the machine base 6. The cutting assembly 221 is connected to the output end of the cutting drive 222 via a cutting transmission assembly. The tubular material output by the conveying mechanism 12 passes through the fixed clamping assembly 211 and then through the cutting assembly 221. The fixed clamping drive 212 drives the fixed clamping assembly 211 to close and fix the tubular material. The cutting drive 222 drives the cutting transmission assembly to rotate the cutting assembly 221, performing circumferential cutting on the cutting assembly 221. In this embodiment, the number of cutting assemblies 221 is the same as the number of fixed clamping assemblies 211, and there is a one-to-one correspondence between the cutting assemblies 221 and the fixed clamping assemblies 211, that is, there are four sets of cutting assemblies 221, all of which are driven by the same cutting drive 222.

[0058] See Figure 3-7 A shaping device includes a shaping conveying mechanism 31 and a shaping mechanism 32. The shaping conveying mechanism 31 and the shaping mechanism 32 are mounted on a machine base 6 along the X-axis. The shaping conveying mechanism 31 is used for conveying pipe segments, and the shaping mechanism 32 is used for shaping the pipe ends of the pipe segments. A cutting device outputs circumferentially cut pipe material along the X-axis. The shaping conveying mechanism 31 clamps the pipe segments from the pipe material, moves the pipe segments along the X-axis, and conveys them to the shaping mechanism 32, which then shapes the pipe ends of the pipe segments.

[0059] The shaping and conveying mechanism 31 includes a shaping clamping assembly 311, a shaping clamping drive 312, and a shaping moving drive 313. The shaping clamping assembly 311 and the shaping clamping drive 312 are mounted on the shaping and conveying carrier 310, with the shaping clamping assembly 311 connected to the output end of the shaping clamping drive 312. The shaping and conveying carrier 310 is slidably mounted on the machine base 6 along the X-axis, and the shaping moving drive 313 is fixedly mounted on the machine base 6. The output end of the shaping moving drive 313 is connected to the input end of the shaping moving transmission assembly, and the output end of the shaping moving transmission assembly is connected to the shaping and conveying carrier 310.

[0060] The shaping and moving drive unit 313 drives the shaping and moving transmission assembly to move the shaping and conveying carrier 310 along the X-axis. The shaping and clamping assembly 311 and the shaping and clamping drive unit 312 move with the shaping and conveying carrier 310. The shaping and clamping drive unit 312 drives the shaping and clamping assembly 311 to open or close to release or clamp the pipe segment. In this embodiment, the shaping and moving drive unit 313 is a rotary motor, and the shaping and moving transmission assembly is a screw drive structure.

[0061] The shaping and clamping assembly 311 includes a shaping and clamping fixed member 3111 and a shaping and clamping moving member 3112. The shaping and clamping fixed member 3111 and the shaping and clamping moving member 3112 are arranged opposite to each other, and the shaping and clamping moving member 3112 is connected to the output end of the shaping and clamping drive member 312. The shaping and clamping drive member 312 drives the shaping and clamping moving member 3112 to move relative to the shaping and clamping fixed member 3111, thereby opening or closing the relationship between the shaping and clamping fixed member 3111 and the shaping and clamping moving member 3112. The shaping and clamping fixed member 3111 and the shaping and clamping moving member 3112 are respectively provided with clamping grooves 3113, which are arranged opposite to each other to facilitate the clamping of the pipe section.

[0062] Specifically, the shaping clamping fixed member 3111 is fixed on the shaping conveying carrier 310, the shaping clamping moving member 3112 is slidably disposed on the shaping conveying carrier 310 along the Y-axis direction, the driving direction of the shaping clamping driving member 312 is along the Z-axis direction, and the output end of the shaping clamping driving member 312 is connected to the shaping clamping transmission member 314, with the shaping clamping moving member 3112 and the shaping clamping transmission member 314 slidably connected. The shaping clamping driving member 312 drives the shaping clamping transmission member 314 to move along the Z-axis direction, and the shaping clamping transmission member 314 drives the shaping clamping moving member 3112 to move along the Y-axis direction. In this embodiment, the shaping clamping driving member 312 is a linear cylinder.

[0063] Furthermore, the shaping clamping transmission member 314 has a clamping transmission inclined portion 3141 and a clamping transmission connecting portion 3142, and the shaping clamping actuator 3112 has a clamping actuator inclined portion 31121 and a clamping actuator connecting portion 31122. The clamping transmission inclined portion 3141 and the clamping actuator inclined portion 31121 are slidably connected, and the clamping transmission connecting portion 3142 and the clamping actuator connecting portion 31122 are slidably connected. When the shaping clamping transmission member 314 moves along the Z-axis direction, it is guided by the cooperation between the clamping transmission connecting portion 3142 and the clamping transmission connecting portion 3142, and driven by the cooperation between the clamping transmission inclined portion 3141 and the clamping actuator inclined portion 31121, so that the shaping clamping actuator 3112 moves along the Y-axis direction. In this embodiment, both the clamping transmission inclined portion 3141 and the clamping actuator inclined portion 31121 are inclined surfaces, and their inclinations are matched. The clamping transmission connection part 3142 is a convex strip, and the clamping moving part connection part 31122 is a groove. The cross-section of the clamping transmission connection part 3142 is trapezoidal, and the shape of the clamping moving part connection part 31122 is adapted to the shape of the clamping transmission connection part 3142.

[0064] Furthermore, there are multiple sets of shaping and clamping assemblies 311, and the number of shaping and clamping assemblies 311 is the same as the number of output ends of the cutting device, with each shaping and clamping assembly 311 corresponding to one output end of the cutting device. As described above, the cutting device has four output ends, and correspondingly, there are also four sets of shaping and clamping assemblies 311.

[0065] In this embodiment, each pair of adjacent shaping clamping components 311 is connected to the output end of the same shaping clamping drive 312. In other words, the same shaping clamping drive 312 drives two adjacent sets of shaping clamping components 311 to open or close. Each shaping clamping transmission component 314 is connected to two shaping clamping actuators 3112. Therefore, in this embodiment, there are two shaping clamping drive components 312 and two shaping clamping transmission components 314. Correspondingly, each shaping clamping transmission component 314 has two clamping transmission inclined portions 3141 and two clamping transmission connecting portions 3142, with the two clamping transmission inclined portions 3141 and the two clamping transmission connecting portions 3142 arranged opposite to each other.

[0066] The shaping mechanism 32 includes a shaping component 321, which is mounted on a shaping support member 320. The shaping support member 320 is movably mounted on the machine base 6 along the Z-axis and is connected to the output end of a shaping displacement drive member 322, which is mounted on the machine base 6. The shaping component 321 includes a first shaping member 3211 and a second shaping member 3212, which are arranged opposite to each other along the X-axis.

[0067] Furthermore, there are multiple sets of shaping components 321, and the number of shaping components 321 is the same as the number of shaping clamping components 311, with each shaping component 321 corresponding to a different shaping clamping component 311. As described above, there are four sets of shaping clamping components 311 and four sets of shaping components 321, arranged side by side.

[0068] The following is a brief description of the working process of this shaping device:

[0069] First, the shaping displacement drive 322 drives the shaping carrier 320 to move the shaping assembly 321 upward along the Z-axis, so that the shaping carrier 320 and the shaping assembly 321 do not obstruct the movement of the shaping conveyor carrier 310 and the shaping clamping assembly 311; then, the shaping clamping assembly 311 is opened by the shaping clamping drive 312, so that each group of shaping clamping moving members 3112 moves relative to the shaping clamping stationary member 3111; next, the shaping movement drive 313 drives the shaping conveyor carrier 310 to move the shaping clamping assembly 311 and the shaping assembly 321 upward along the Z-axis, so that the shaping carrier 320 and the shaping assembly 321 do not obstruct the movement of the shaping conveyor carrier 310 and the shaping clamping assembly 311. The shaping clamping drive 312 moves towards the output end of the cutting device, causing the shaping clamping assembly 311 to move to the output of the circumferentially cut pipe material. The pipe segment at the front end of the pipe material passes between the corresponding shaping clamping stationary 3111 and the shaping clamping moving 3112. Next, the shaping clamping drive 312 drives each group of shaping clamping moving 3112 to move relative to the shaping clamping stationary 3111, causing the shaping clamping moving 3112 and the shaping clamping stationary 3111 to clamp the pipe segment at the front end of the pipe material. Subsequently, the shaping movement drive 313 drives the shaping... The forming conveyor 310 drives the forming clamping assembly 311 and the forming clamping drive 312 away from the output end of the cutting device to separate the pipe section at the front end of the pipe material; the forming movement drive 313 continues to drive the forming conveyor 310 to move the forming clamping assembly 311 and the forming clamping drive 312 until the forming clamping assembly 311 moves below the forming carrier 320, at which point the forming movement drive 313 stops driving; then, the forming displacement drive 322 drives the forming carrier 320 to move the forming assembly 321 along the Z-axis. The tube segment moves downwards, aligning the shaping assembly 321 with the end of the tube segment on the shaping clamping assembly 311. Next, the shaping movement drive 313 drives the shaping conveying carrier 310 to move the shaping clamping assembly 311 back and forth along the X-axis, causing the two ends of the tube segment on the shaping clamping assembly 311 to be successively inserted into the first shaping component 3211 and the second shaping component 3212, thus achieving tube end shaping. Finally, the shaping clamping assembly 311 is driven open by the shaping clamping drive 312 to release the tube segment, and the transfer device receives the tube segment with the completed tube end shaping. This process is repeated continuously.

[0070] In summary, the shaping and conveying mechanism of this shaping device receives pipe segments along the X-axis and conveys them to the shaping mechanism along the X-axis. That is, the picking and shaping of pipe segments are both completed in the X-axis direction, which simplifies the receiving and conveying routes of pipe segments, eliminates the need for material collection, shaping, and reloading, saves time, and thus improves production efficiency.

Preferably, to improve the movement stability of the transfer carrier component 40, a drag chain 71 is also provided on the transfer carrier frame 7, and the drag chain 71 is connected to the transfer carrier component 40.

[0074] The transfer mechanism 42 includes a transfer drive assembly 421, a transfer pitch change assembly 422, and two sets of transfer clamping assemblies 423. The transfer drive assembly 421 is mounted on the transfer carrier 40. The transfer pitch change assembly 422 and the two sets of transfer clamping assemblies 423 are connected to the output end of the transfer drive assembly 421, and the two sets of transfer clamping assemblies 423 are connected to the output end of the transfer pitch change assembly 422. The transfer drive assembly 421 drives the transfer pitch change assembly 422 and the two sets of transfer clamping assemblies 423 to move along the Z-axis, and the transfer pitch change assembly 422 drives the two sets of transfer clamping assemblies 423 to move relative to each other along the Y-axis.

[0075] The transfer drive assembly 421 includes a first transfer drive member 4211 and a second transfer drive member 4212. The first transfer drive member 4211 is mounted on the transfer carrier 40, and the second transfer drive member 4212 is mounted on the transfer connector 424. The transfer connector 424 is movably connected to the transfer carrier 40 via a transfer drive guide member 4241. The output end of the first transfer drive member 4211 is connected to the output end of the second transfer drive member 4212, and the driving directions of both the first transfer drive member 4211 and the second transfer drive member 4212 are along the Z-axis.

[0076] The transfer pitch component 422 is mounted on the transfer connector 424, and two sets of transfer clamping components 423 are slidably mounted on the end of the transfer connector 424 away from the second transfer drive component 4212. The two sets of transfer clamping components 423 are arranged along the Y-axis direction, and the output end of the transfer pitch component 422 is connected to the two sets of transfer clamping components 423.

[0077] The transfer pitch-changing assembly 422 includes a transfer pitch-changing drive 4221, a transfer pitch-changing linkage 4222, and two transfer pitch-changing transmission components 4223. The transfer pitch-changing drive 4221 is fixed in the transfer connector 424. The transfer pitch-changing linkage 4222 is connected to the output end of the transfer pitch-changing drive 4221, and extends through the transfer connector 424 at the end furthest from the second transfer drive 4212. The two transfer pitch-changing transmission components 4223 are arranged opposite to each other, and both are slidably connected to the transfer pitch-changing linkage 4222. Each of the two transfer pitch-changing transmission components 4223 is connected to one of the two sets of transfer clamping assemblies 423.

[0078] Specifically, the driving direction of the transfer pitch drive 4221 is along the Z-axis, and the transfer pitch drive 4221 drives the transfer pitch linkage 4222 to move along the Z-axis. A V-shaped pitch linkage connection portion 42221 is provided at the end of the transfer pitch linkage 4222 away from the transfer pitch drive 4221, that is, the pitch linkage connection portion 42221 has two inclined surfaces 422211. The two transfer pitch transmission members 4223 are each provided with a pitch transmission connection portion 42231, and the two pitch transmission connection portions 42231 are slidably connected to both sides of the pitch linkage connection portion 42221. In this embodiment, the pitch transmission connection portion 42231 is an inclined groove, and the shape of the pitch transmission connection portion 42231 is adapted to the inclined surface 422211 of the pitch linkage connection portion 42221.

[0079] Furthermore, the pitch-changing linkage connection part 42221 is also provided with at least two pitch-changing guide positions 42222, and each transfer pitch-changing transmission member 4223 is provided with at least one pitch-changing guide part 42232. The pitch-changing guide parts 42232 and the pitch-changing guide positions 42222 are slidably connected one-to-one, so that the two pitch-changing transmission connection parts 42231 can maintain linkage with the pitch-changing linkage connection part 42221. The pitch-changing guide positions 42222 are inclined, and the inclination of the pitch-changing guide positions 42222 is consistent with the inclination of the inclined surface 422211 of the pitch-changing linkage connection part 42221. Correspondingly, the pitch-changing guide parts 42232 are also inclined, and the inclination of the pitch-changing guide parts 42232 is consistent with the inclination of the corresponding pitch-changing guide positions 42222.

[0080] Furthermore, there are four pitch guide positions 42222, which are arranged in pairs on opposite sides of the pitch linkage connection part 42221, with the two pitch guide positions 42222 on the same side arranged in a V-shape. Correspondingly, each transfer pitch transmission component 4223 has two pitch guide parts 42232, which are symmetrically arranged on the pitch transmission connection part 42231. The pitch guide parts 42232 and the pitch guide positions 42222 are slidably connected one-to-one, improving the stability of the linkage. In this embodiment, the pitch guide position 42222 is a groove, and the pitch guide part 42232 is a convex strip.

[0081] When the transfer pitch linkage 4222 moves along the Z-axis, the two transfer pitch transmission components 4223 are linked together under the cooperation of the pitch guide position 42222 and the pitch guide part 42232, which drives the two pitch transmission connecting parts 42231 to move along the two inclined surfaces 422211 of the pitch linkage connecting part 42221, thereby causing the two transfer pitch transmission components 4223 to move relative to each other along the Y-axis, thereby driving the two sets of transfer clamping assemblies 423 to move relative to each other along the Y-axis.

[0082] Two sets of transfer clamping assemblies 423 are arranged side by side. Each transfer clamping assembly 423 includes a transfer clamping drive 4231 and two transfer clamping members 4232. The transfer clamping drive 4231 is slidably mounted on the end of the transfer connector 424 away from the second transfer drive 4212 and fixedly connected to the adjacent transfer pitch transmission member 4223. The transfer clamping drive 4231 is arranged along the Y-axis. The two transfer clamping members 4232 are connected to the output end of the transfer clamping drive 4231. The transfer clamping drive 4231 drives the two transfer clamping members 4232 to open or close, thereby releasing or clamping the pipe section.

[0083] In specific applications: the transfer drive 411 drives the transfer carrier 40 to move the transfer mechanism 42 along the X-axis, moving back and forth between the shaping device and the bending device; the first transfer drive 4211 and the second transfer drive 4212 drive the transfer pitch assembly 422 and the two sets of transfer clamping assemblies 423 to move along the Z-axis; the transfer pitch drive 4221 drives the transfer pitch linkage 4222 to move along the Z-axis, and the transfer pitch linkage 4222 drives the two pitch transmission connecting parts 42231 to move relative to each other along the Y-axis, thereby driving the two sets of transfer clamping assemblies 423 to move relative to each other along the Y-axis; the transfer clamping drive 4231 drives the two transfer clamping parts 4232 to release or clamp the pipe section.

[0084] To accommodate different workstations, two sets of transfer mechanisms 42 are arranged side-by-side on the transfer carrier 40. This variable-pitch transfer device includes a transfer pitch-changing component. This component drives the two sets of transfer clamping components to move relative to each other along the Y-axis, changing their relative positions. This alters the spacing between the clamping pipe sections, adapting to different workstation spacings and simultaneously meeting the requirements of simple design, low cost, and high efficiency.

[0085] See Figure 14-21 The pipe bending device 5 includes a pipe bending loading mechanism 51, a pipe bending mechanism 52, and a pipe bending drive mechanism 53. The pipe bending loading mechanism 51 and the pipe bending drive mechanism 53 are mounted on a pipe bending support member 50, which is installed on a machine base 6. The pipe bending mechanism 52 is connected to the output end of the pipe bending drive mechanism 53, and the pipe bending mechanism 52 and the pipe bending top mechanism 54 are located on opposite sides of the pipe bending loading mechanism 51. The pipe bending loading mechanism 51 carries the pipe segment to be processed, the pipe bending mechanism 52 clamps the pipe segment, and the pipe bending drive mechanism 53 drives the pipe bending mechanism 52 to rotate. The pipe bending mechanism 52 causes the pipe segment to bend, thus achieving pipe bending.

[0086] The pipe bending loading mechanism 51 includes multiple pipe bending loading modules 511, which are arranged side-by-side on the pipe bending support member 510, which in turn is mounted on the pipe bending support member 50. Each pipe bending loading module 511 has only one loading position 5111, which can only accommodate a single pipe segment; in other words, each pipe bending loading module 511 only supports a single pipe segment, ensuring the support provided by the pipe bending loading module 511 for the pipe segment. In this embodiment, there are four pipe bending loading modules 511, and the loading positions 5111 are U-shaped grooves.

[0087] Furthermore, the pipe bending material loading mechanism 51 also includes a first material loading template drive 512 and a second material loading template drive 513. Driven by the first and second material loading template drives 512 and 513, the pipe bending material loading template 511 is brought as close as possible to the pipe bending template of the pipe bending mechanism 52, ensuring the pipe bending effect. Specifically, the first material loading template drive 512 is mounted on the pipe bending support 50, and the pipe bending material loading support 510 is slidably mounted on the pipe bending support 50 along the X-axis direction. The output end of the first material loading template drive 512 is connected to the pipe bending material loading support 510 through the first material loading transmission assembly 514. The number of the second material-carrying template drive members 513 is the same as the number of the bending pipe material-carrying modules 511, and there is a one-to-one correspondence between the second material-carrying template drive members 513 and the bending pipe material-carrying modules 511. Multiple second material-carrying template drive members 513 are installed side-by-side on the bending pipe material-carrying support member 510, and multiple bending pipe material-carrying modules 511 are movably installed on the bending pipe material-carrying support member 510.

In this embodiment, the first material-carrying template drive member 512 is a motor, the first material-carrying transmission group 514 is a screw drive mechanism, and the second material-carrying template drive member 513 is a hydraulic cylinder.

[0088] The first material-carrying template drive 512 drives the first material-carrying transmission group 514 to move the bent pipe material-carrying component 510 along the X-axis direction, and multiple bent pipe material-carrying modules 511 move with the bent pipe material-carrying component 510; the second material-carrying template drive 513 drives the second material-carrying transmission group 515 to move the corresponding bent pipe material-carrying module 511 along the Z-axis direction.

[0089] The pipe bending mechanism 52 and the pipe bending loading mechanism 51 are arranged opposite each other along the X-axis. The mechanism includes multiple sets of pipe bending modules 522, the number of which is the same as the number of pipe bending loading modules 511, with each set of modules corresponding to one of the modules. The multiple sets of modules 522 are arranged side-by-side on the pipe bending support 521, which is connected to the output end of the pipe bending drive mechanism 53. Each set of modules 522 clamps a pipe segment, and the pipe bending drive mechanism 53 drives the pipe bending support 521 to rotate the multiple sets of modules 522, thus bending the pipe segment. Among them, the single-unit pipe bending module 522 can only clamp a single pipe segment, that is, the single-unit pipe bending module 522 only clamps the pipe segment on the corresponding pipe bending loading module 511, ensuring the clamping force of the pipe bending module 522 on the pipe segment.

[0090] Specifically, the single-unit pipe bending module 522 includes a pipe bending die 5221, a pipe bending clamping die 5222, and a pipe bending clamping die drive 5223. The pipe bending die 5221 is fixedly installed on the pipe bending support 521, and the pipe bending clamping die 5222 is movably installed on the pipe bending support 521. The pipe bending die 5221 and the pipe bending clamping die 5222 are arranged vertically opposite each other. The pipe bending clamping die drive 5223 is installed on the pipe bending support 521, and the output end of the pipe bending clamping die drive 5223 is connected to the pipe bending clamping die 5222.

[0091] The pipe bending die drive 5223 drives the pipe bending die 5222 to move closer to or away from the pipe bending die 5221, causing the pipe bending die 5221 and the pipe bending die 5222 to clamp or release the pipe segment. Preferably, for ease of installation and cost savings, the pipe bending die drive 5223 of multiple sets of pipe bending dies 522 uses the same pipe bending die drive seat 523, but each pipe bending die drive 5223 can work independently. In this embodiment, the pipe bending die drive 5223 is a hydraulic cylinder piston rod, and the pipe bending die drive seat 523 is a hydraulic cylinder.

[0092] The pipe bending drive mechanism 53 includes a pipe bending drive component 531 and a pipe bending transmission component 532. The pipe bending drive component 531 is mounted on the pipe bending support component 50 via the pipe bending drive support component 533. One end of the pipe bending transmission component 532 is connected to the output end of the pipe bending drive component 531, and the other end of the pipe bending transmission component 532 is connected to one end of the pipe bending mold drive seat 523. The pipe bending drive component 531 drives the pipe bending transmission component 532 to rotate the pipe bending mold drive seat 523, and multiple sets of pipe bending and bending modules 522 rotate with the pipe bending mold drive seat 523.

[0093] To improve operational stability, a bending auxiliary component 534 is connected to the other end of the bending die drive seat 523. The bending auxiliary component 534 is rotatably mounted on the bending transmission support component 535, which is fixed on the bending support component 50.

[0094] Furthermore, it also includes a pipe bending and ejecting mechanism 54, which is used to push and eject the pipe section on the pipe bending and loading mechanism 51. The pipe bending and ejecting mechanism 54 includes a pipe bending and ejecting drive 541 and a pipe bending and ejecting component 542, wherein the pipe bending and ejecting drive 541 drives the pipe bending and ejecting component 542 to move along the X-axis.

[0095] A pipe bending ejector drive 541 is mounted on a pipe bending ejector mounting 543, which in turn is mounted on a pipe bending support 50. The number of pipe bending ejector components 542 is the same as the number of pipe bending support modules 511, and each ejector component 542 corresponds one-to-one with a different pipe bending support module 511. Multiple ejector components 542 are arranged side-by-side on a pipe bending ejector support 544, which is slidably mounted on the pipe bending mounting 543 and connected to the output end of the pipe bending ejector drive 541. In this embodiment, the pipe bending ejector drive 541 is a linear cylinder.

[0096] The bending pipe ejector drive 541 drives the bending pipe ejector carrier 544 to move multiple bending pipe ejector components 542 along the X-axis. After the bending pipe ejector component 542 enters the loading position 5111 of the corresponding bending pipe loading mold 511, it is inserted into the pipe section and pushes the pipe section between the corresponding bending pipe clamping mold 5222 and bending pipe bending mold 5221.

[0097] Furthermore, it also includes a pipe bending unloading mechanism 55, which is used to unload the pipe section that has completed the bending process on the pipe bending loading mechanism 51. The pipe bending unloading mechanism 55 includes a pipe bending unloading drive 551 and a pipe bending unloading assembly 552, wherein the pipe bending unloading drive 551 drives the pipe bending unloading assembly 552 to move along the X-axis.

[0098] A pipe bending ejection drive unit 551 is installed at the bottom of the pipe bending support unit 50, and the output end of the pipe bending ejection drive unit 551 is connected to the input end of the pipe bending ejection transmission group 553. The number of pipe bending ejection assemblies 552 is the same as the number of pipe bending loading modules 511, and multiple sets of pipe bending ejection assemblies 552 correspond one-to-one with multiple pipe bending loading modules 511. Multiple sets of pipe bending ejection assemblies 552 are arranged side by side on the pipe bending ejection support unit 554, which is slidably mounted on the pipe bending top material mounting unit 543, and is connected to the output end of the pipe bending ejection transmission group 553. The single-unit tube bending ejection assembly 552 includes a first tube bending ejection component 5521 and a second tube bending ejection component 5522. The first tube bending ejection component 5521 and the second tube bending ejection component 5522 are arranged side by side, one above the other, and the first tube bending ejection component 5521 is fitted onto the adjacent tube bending top component 542. In this embodiment, the tube bending ejection drive component 551 is a rotary motor, and the tube bending ejection transmission assembly 553 adopts a screw drive structure.

[0099] The bending tube ejection drive unit 551 drives the bending tube ejection transmission group 553 to move the bending tube ejection carrier 554 along the X-axis. Multiple bending tube ejection assemblies 552 move with the bending tube ejection carrier 554. The bending tube ejection assemblies 552 push the pipe segment that has completed the bending process on the corresponding bending tube loading module 511, so that the pipe segment is separated from the bending tube top material component 542 and moves the pipe segment to a suitable position for easy unloading.

[0100] In order for the pipe ejector 542 and the pipe ejector assembly 552 to accurately push the pipe section, each pipe loading module 511 is provided with an ejector guide 516, and the pipe ejector 542 and the pipe ejector assembly 552 are inserted into the corresponding ejector guide 516.

[0101] Furthermore, it also includes a pipe bending end mechanism 56, which is used to prevent pipe end deformation during pipe bending. The pipe bending end mechanism 56 is arranged opposite to the pipe bending and bending mechanism 52 along the X-axis, and includes a pipe bending end drive assembly 561 and a pipe bending end piece 562. The pipe bending end drive assembly 561 drives the pipe bending end piece 562 to move along the X-axis or Z-axis. The number of pipe bending end pieces 562 is the same as the number of pipe bending loading modules 511, and multiple pipe bending end pieces 562 correspond one-to-one with multiple pipe bending loading modules 511, and every two pipe bending end pieces 562 share a set of pipe bending end drive assemblies 561.

[0102] The single-unit pipe bending end drive assembly 561 includes a first pipe bending end drive component 5611 and a second pipe bending end drive component 5612. The first pipe bending end drive component 5611 is mounted on the side of the pipe bending clamping mold drive seat 523. The output end of the first pipe bending end drive component 5611 is connected to a pipe bending end transmission component 563. The second pipe bending end drive component 5612 is mounted on the pipe bending end transmission component 563. The output end of the second pipe bending end drive component 5612 is connected to a pipe bending end support component 564, and the pipe bending end support component 564 is slidably disposed on the pipe bending end transmission component 563. The two pipe bending end components 562 are mounted side by side on the pipe bending end support component 564.

[0103] The second pipe end drive component 5612 drives the pipe end bearing component 564 to move the two pipe end components 562 along the Z-axis, aligning the pipe end components 562 with the pipe segments on the corresponding pipe loading mold 511. The first pipe end drive component 5611 drives the pipe end transmission component 563 to move both the first pipe end drive component 5611 and the pipe end bearing component 564 along the X-axis, inserting the pipe end components 562 with the pipe segments on the corresponding pipe loading mold 511. This insertion ensures that the pipe segments do not deform during the bending process. After bending, the pipe end mechanism 56 resets, and the pipe end components 562 separate from the corresponding pipe segments, preventing the pipe end mechanism 56 from affecting the pipe segment feeding.

[0104] The following is a brief explanation of the working process of this multi-station pipe bending device:

[0105] First, the transfer device 4 transfers the shaped pipe segment to the pipe bending loading mechanism 51, where a single pipe bending loading module 511 carries a single pipe segment. Then, the pipe bending ejector drive 541 drives multiple pipe bending ejectors 542 to move, and each ejector pushes the pipe segment on the corresponding pipe bending loading module 511, moving one section of the pipe segment into the corresponding pipe bending module 522. Next, the pipe bending clamping drive 5223 drives the pipe bending clamping module 52... 22 moves along the Z-axis, clamping the pipe segment between the pipe bending die 5222 and the pipe bending die 5221; then, the pipe bending ejector drive 541 drives the pipe bending ejector 542 to move, inserting the pipe bending ejector 542 into one end of the pipe segment; simultaneously, the pipe bending end drive assembly 561 drives the pipe bending end piece 562 to move, inserting the pipe bending end piece 562 into the other end of the pipe segment; subsequently, the pipe bending drive 531 drives the pipe bending transmission 532 to move the pipe bending... The clamping mold drive seat 523 flips, and multiple sets of pipe bending and bending modules 522 rotate with the pipe bending clamping mold drive seat 523, thereby realizing the bending of the pipe segment; after the pipe bending is completed, the pipe bending end drive assembly 561 drives the pipe bending end piece 562 to move, so that the pipe bending end piece 562 separates from the pipe segment and ensures that the pipe bending end piece 562 does not obstruct the pipe segment. At the same time, the pipe bending mold drive assembly 5223 drives the pipe bending mold assembly 5222 to move to release the pipe segment; next, the pipe bending ejection drive... The actuator 551 drives the pipe bending ejection assembly 552 to push the pipe segment, causing the pipe bending ejector 542 to separate from the pipe segment and push the pipe segment away from the pipe bending module 522 to the unloading point. Finally, the pipe bending ejection drive 551 drives the pipe bending ejection assembly 552 to reset, the pipe bending ejector drive 541 drives multiple pipe bending ejectors 542 to reset, and the pipe bending drive 531 drives multiple sets of pipe bending modules 522 to reset, in preparation for bending the next batch of pipe segments. This cycle repeats continuously.

[0106] In this multi-station pipe bending device, the pipe bending loading mechanism includes multiple pipe bending loading modules, with each module carrying a single pipe segment. Correspondingly, the pipe bending mechanism includes multiple sets of bending modules, with each module clamping or releasing the pipe segment on the corresponding loading module. This ensures that the multiple loading modules and the multiple bending modules are relatively independent and do not interfere with each other. This guarantees both the support of the loading modules for the pipe segments and the clamping force of the bending modules, thereby ensuring the bending effect of each pipe segment, improving product quality, and increasing the product qualification rate.

[0107] The following is a brief description of the working process of the combined zero-waste short pipe bending machine:

[0108] First, the pipe material on the tray is straightened by the straightening mechanism 11, and then transported by the conveying mechanism 12 to the cutting mechanism 22, exposing a section of pipe material facing the shaping mechanism 32. Next, the fixing mechanism 21 clamps and fixes the pipe material, and the cutting mechanism 22 performs a circumferential cut on the pipe material, thus segmenting it. Then, the shaping and conveying mechanism 31 clamps the segmented pipe material and moves it along the X-axis, separating the segmented pipe material from the original pipe material. Finally, the shaping and conveying mechanism 31 moves the pipe segment along the X-axis to the forming mechanism 32. After pipe end shaping is completed, the shaping conveying mechanism 31 releases the pipe segment. Subsequently, the transfer moving mechanism 41 drives the transfer mechanism 42 to move to the shaping conveying mechanism 31. The transfer mechanism 42 clamps the pipe segment on the shaping conveying mechanism 31, and the transfer moving mechanism 41 drives the transfer mechanism 42 to transfer the pipe segment to the pipe bending loading mechanism 51. Finally, the pipe bending mechanism 52 clamps the pipe segment on the pipe bending loading mechanism 51, and the pipe bending drive mechanism 53 drives the pipe bending loading mechanism 51 to bend the pipe segment, thus achieving pipe bending and obtaining the finished pipe. The pipe bending unloading mechanism then unloads the finished pipe. This process is repeated continuously.

[0109] In summary, this combined, waste-free short pipe bending machine sequentially arranges the straightening device, cutting device, shaping device, and bending device along the X-axis, ensuring that the transport of pipes between each device is completed in the X-axis direction. This simplifies the pipe processing and transport route, eliminates the need for material collection and secondary feeding mechanisms, material straightening, and reloading, saving the process and costs associated with secondary feeding, saving time, reducing the probability of unexpected malfunctions, and thus improving production efficiency. Furthermore, the process also meets environmental protection requirements.
