Description

Technical Field

[0001] The utility model relates to the field of pipeline production equipment, in particular to a pipeline prefabrication threading production combined line. Background Art

[0002] In the construction of fire protection systems, the installation and connection of fire protection pipes is a crucial link. The quality of fire protection pipes is directly related to the effectiveness of the fire protection system when a fire occurs. Therefore, the threading process of fire protection pipes is particularly critical. The traditional threading process of fire protection pipes usually relies on manual operation, which is not only inefficient, but also difficult to ensure the quality and consistency of threading. In addition, due to the high labor intensity of manual operation and the relatively harsh working environment, the skills and experience requirements of the operators are high, which further increases production costs and safety hazards.

[0003] In recent years, with the rapid development of automation technology, more and more industries have begun to try to introduce automation equipment to improve production efficiency and quality. In the field of fire pipe threading, the introduction of automation technology is also particularly urgent. By introducing an automated production line, the fire pipe threading process can be automated, intelligent and efficient, thereby greatly improving production efficiency and quality, reducing labor intensity and reducing human errors.

[0004] However, there are already some fire pipe threading automation equipment on the market, but these equipment often have single functions and cannot realize the automation of the entire threading process. For example, some equipment can only realize automatic feeding or automatic cutting, but cannot realize functions such as automatic threading or automatic storage. In addition, the cooperation and coordination between these equipment is not close enough, resulting in low efficiency of the entire production line.

[0005] Therefore, it is necessary to develop a technical solution that can solve the above problems. Utility Model Content

[0063] Automatic pipe feeding device

[0064] refer to Figures 2 to 7 As shown, the automatic pipe loading device 200 includes a material rack 210, a loading structure 250 and a top-leveling structure 240. The pipes 100 are placed on the material rack 210 for storage, and can be taken out and loaded through the loading structure 250. The top-leveling structure 240 can top-level the pipes 100 placed at different positions so that they can be loaded at a predetermined position.

[0065] refer to Figure 2 , Figure 4 The material rack 210 includes a support column 211 and at least two cross bars 212 arranged on the support column 211. Specifically, in the present embodiment, the support column 211 is a columnar structure with a substantially I-shaped cross section, the bottom of which can be fixed to the ground or other supporting surfaces by bolts, the cross bars 212 are supported on the support column 211 along the third direction, and at least two cross bars 212 are arranged parallel to each other. When placing the pipeline 100, the pipeline 100 is placed on the cross bars 212 along the first direction, so that the pipeline 100 is supported on the plane formed by the at least two cross bars 212.

[0066] Furthermore, at least one limiting protrusion 2121 is provided on the material rack 210 to prevent the pipe 100 from rolling out on the material rack 210. Specifically, in this embodiment, two limiting protrusions 2121 are provided on the cross bar 212 of the material rack 210, and the two limiting protrusions 2121 are respectively arranged at both ends of the cross bar 212, that is, on both sides of the third direction of the material rack 210. When the pipe 100 is placed on the cross bar 212 along the first direction, even if the pipe 100 rolls on the cross bar 212 along the third direction, the limiting protrusion 2121 can prevent the pipe 100 from rolling out of the range of the cross bar 212.

[0067] Optionally, in some other embodiments, the cross bar 212 on the rack 210 for supporting the pipe 100 may be slightly tilted, and only the limiting protrusion 2121 is set at the lower end of the tilted cross bar 212 , as long as the pipe 100 does not roll out of the rack 210 .

[0068] The rack 210 is also provided with a flipping structure 220 for flipping the pipe 100 on the rack 210. Figure 2 and Figure 5In this embodiment, the flip structure 220 is arranged on one side of the third direction of the material rack 210, and mainly includes a flip driving device 221 and a flip member 222 installed on the material rack 210 and driven to rotate by the flip driving device 221. The flip driving device 221 is preferably a driving cylinder, and the flip member 222 is a roughly 7-shaped structure, the middle of which is installed on the cross bar 212 through a rotating shaft 223 and can rotate. One end of the flip member 222 is connected to the driving end of the flip driving device 221. When flipping is required, the flip driving device 221 drives the flip member 222 to flip, and the other end of the flip member 222 that is not connected to the flip driving device 221 can abut against the pipe 100 on the cross bar 212, and the pipe 100 is flipped, thereby realizing the flipping of the pipe 100 on the material rack 210.

[0069] refer to Figure 2 and Figure 3 The flip structure 220 also includes a blocking protrusion 224, which can be used to cooperate with the flip member 222 to separate the pipe 100 on the material rack 210 separately, so as to facilitate the loading structure 250 to load the material after taking the material. Specifically, in this embodiment, the blocking protrusion 224 is arranged on the inner side of the limiting protrusion 2121 at one end of the cross bar 212 where the flip structure 220 is arranged. The blocking protrusion 224 separates the material rack 210 in the third direction into a pre-stored pipe material storage space 210a and a loading space 210b prepared for pipe loading. It can also be said that the blocking protrusion 224 and the limiting protrusion 2121 form a loading space for a single limited pipe 100. When the pipe 100 is placed on the cross bar 212, it is located in the loading space 210a (located on the side where the blocking protrusion 224 is away from the limiting protrusion 2121), and the flipping structure 220 works on the cross bar 212. When the flipping member 222 flips, it can flip the pipe 100 from the original loading space 210a to the loading space 210b, that is, from the side where the blocking protrusion 224 is away from the limiting protrusion 2121 to the side where the blocking protrusion 224 is close to the limiting protrusion 2121, flip the pipe 100 between the blocking protrusion 224 and the limiting protrusion 2121, and separate the pipe 100 from other pipes 100.

[0070] Optionally, a crane blocking plate 230 is further provided on one side of the rack 210, so that the staff can have a visual mark when hoisting the pipe 100 to the rack 210. Specifically, in this embodiment, the crane blocking plate 230 is provided at one end of the rack 210 in the first direction.

[0071] The flattening structure 240 can flatten the pipe 100 on the side of the rack 210 where the flipping structure 220 is provided. That is, after the flipping structure 220 separates the pipe 100 into the loading space 210b, the flattening structure 240 can flatten the pipe 100 in the loading space to a predetermined position.

[0072] The top flat structure 240 is at least partially disposed on the material rack 210. Figure 2 In this embodiment, the top-leveling structure 240 includes a blocking plate 241 and a top-leveling plate 242 movably mounted on the material rack 210. Preferably, the material rack 210 is provided with a top-leveling driving device 244, and the top-leveling driving device 244 is preferably a driving cylinder. The top-leveling plate 242 is movably mounted on the material rack 210 through a guide rod 245, such as being mounted on a support column 211 of the material rack 210, and the driving end of the top-leveling driving device 244 is connected to the guide rod 245. In the first direction, the blocking plate 241 and the top-leveling plate 242 are arranged opposite to each other. Moreover, the top plate 242 can level the pipe turned over by the turning structure 220 in the loading space 210b, that is, when the turning structure 220 turns over the pipe 100, the pipe 100 can be turned over separately between the blocking plate 241 and the top plate 242. The leveling drive device 244 can drive the guide rod 245 to move on the material rack 210, so that the top plate 242 moves in the first direction, abuts the top plate 242 against one end of the pipe 100, and pushes the pipe 100 to move in the first direction until the other end thereof abuts against the blocking plate 241. At this time, the pipe 100 reaches a predetermined position in the loading space.

[0073] Furthermore, a universal pin 243 is provided on one side of the top plate 242 for contacting with the pipe 100. The universal pin 243 can be elastically moved on the top plate 242 to adapt to different pipes 100. Figure 6 In this embodiment, the top plate 242 is provided with a plurality of mounting holes, and a plurality of universal pins 243 are installed in the plurality of mounting holes and installed on the side of the top plate 242 that abuts against the pipe 100, and an elastic member, preferably a spring, can be provided in the mounting hole, and the spring is provided in the mounting hole to provide elastic force for the universal pins 243, so that the universal pins 243 can be elastically moved on the top plate 242. The rear end of the pipe 100 is uneven, and the standard pipe length of the pipe 100 has a deviation of plus or minus 5 mm. Therefore, when the pipe 100 abuts against the top plate 242, the rear end abuts against the universal pins 243, thereby pushing the pipe 100, that is, ensuring that the other end of the pipe 100 is flush.

[0074] It should be noted that in some other embodiments, the loading space 210b between the blocking protrusion 224 and the limiting protrusion 2121 can also store multiple pipes, and separating a single pipe 100 is just a way to make it easier for the loading structure 250 to take out the material. When there are multiple pipes, the top flat driving device 244 pushes the entire mechanism of the top plate 242 to push the multiple pipes 100, and the universal needle 243 set on the top plate 242 ensures that the front ends of the multiple pipes are flush, while the rear ends of the pipes 100 are uneven, and the standard pipe lengths between the multiple pipes 100 have a deviation of plus or minus 5 mm.

[0075] Optionally, in some other embodiments, the leveling structure 240 may not be provided on the material rack 210 , as long as it can level the pipeline 100 on the side of the material rack 210 where the flip structure 220 is provided.

[0076] It should be noted that the flattening structure 240 corresponds to the position of the pipe 100 separated by the flipping structure 220 on the material rack 210. More precisely, it is used to flatten the pipe 100 separated by the flipping structure 220 on the material rack 210 so that it reaches a predetermined position and is clamped by the loading structure 250 for loading.

[0077] refer to Figure 2 , Figure 7 The feeding structure 250 is arranged on one side of the material rack 210, and is used to extend to the material rack 210 to clamp the pipe 100 for feeding. Optionally, the feeding structure 250 is arranged on one side of the material rack 210 in the third direction, and the feeding structure 250 is at least partially located below the material rack 210, and can be lifted and moved in the third direction to reach the material rack 210 for taking materials.

[0078] Specifically, in this embodiment, the loading structure 250 includes a loading base 251 fixed on the ground or any supporting surface and a clamping assembly 252 arranged on the loading base 251. The clamping assembly 252 is raised and lowered on the loading base 251, and the clamping assembly 252 can also move along a third direction on the loading base 251, so as to clamp the pipe 100 and move it away from the material rack 210 for loading.

[0079] The feeding structure 250 also includes a first bottom plate 254 and a second bottom plate 255. The first bottom plate 254 is installed on the feeding base 251 through a guide column 256 and can be lifted and lowered. The clamping assembly 252 is installed on the second bottom plate 255, and the bottom of the second bottom plate 255 is provided with a first guide rail 2551 set along a third direction, and the top surface of the first bottom plate 254 is provided with a first slider 2541 set along the third direction. The second bottom plate 255 can be moved on the first bottom plate 254 through the cooperation of the first guide rail 2551 and the first slider 2541, so that the clamping assembly 252 can be lifted and lowered and moved in the third direction.

[0080] A lifting drive device 257 is provided on the loading base 251, preferably a driving cylinder. The first base plate 254 is installed on the loading base 251 through the guide column 256 so that it can be lifted and lowered, and the first base plate 254 is connected to the driving end of the lifting drive device 257, and can be lifted and lowered by the lifting drive device 257.

[0081] A mobile driving device 258 is also provided on the top surface of the first bottom plate 254, and a driving end of the mobile driving device 258 is connected to the second bottom plate 255. By driving the mobile driving device 258, the second bottom plate 255 can be moved along the third direction on the first bottom plate 254, so that the clamping component 252 can clamp the pipe 100 and then load the pipe in a direction away from the material rack 210 along the width.

[0082] The material clamping assembly 252 includes a loading clamping block 2521 movably arranged on the second base plate 255 and a material clamping driving device 253. The second base plate 255 is provided with a second guide rail 2552 arranged along a third direction. Two loading clamping blocks 2521 are arranged. The two loading clamping blocks 2521 are both movably installed on the second base plate 255 and on the second guide rail 2552, and are arranged relatively along the third direction. The second base plate 255 is also provided with a rotatable first meshing tooth 2553, and the two loading clamps 2521 are both provided with a rack 2522. When the two loading clamps 2521 are relatively arranged on the second base plate 255, the first meshing tooth 2553 is arranged between the two loading clamps 2521, and the racks 2522 of the two loading clamps 2521 are both meshed with the first meshing tooth 2553. The driving end of the clamping drive device 253 is connected to one of the loading clamps 2521. When one of the loading clamps 2521 is driven to move, the first meshing tooth 2553 is driven to rotate, and the other loading clamp 2521 is driven to move through the first meshing tooth 2553. Preferably, the two loading clamps 2521 are arranged to move relative to each other, so that the clamping assembly 252 can clamp or loosen the pipe 100 through the loading clamp 2521.

[0083] Furthermore, the loading clamp block 2521 is a substantially V-shaped structure, so that when it is relatively arranged, it can clamp pipes 100 of different specifications. And the loading clamp block 2521 of the V-shaped structure is also provided with a plurality of teeth 2523 to ensure that the loading clamp block 2521 can clamp the pipe 100.

[0084] The pipe 100 is stored on the material rack 210 . When in use, the flip structure 220 works, and the flip member 222 flips the single pipe 100 , so that the loading space between the blocking protrusion 224 and the limiting protrusion 2121 is separately separated.

[0085] At this time, the top leveling structure 240 is working, and the top leveling driving device 244 drives the top plate 242 to move on the material rack 210. The top plate 242 abuts against one end of the single pipe 100 between the blocking protrusion 224 and the limiting protrusion 2121, pushing the pipe 100 to move until the other end of the pipe 100 abuts against the blocking plate 241. The pipe 100 reaches the predetermined position and the top leveling structure 240 stops working.

[0086] Finally, the feeding structure 250 works, and the lifting drive device 257 works, the clamping assembly 252 rises on the feeding base 251 and reaches the position of the separately separated pipe 100 on the material rack 211. The clamping drive device 253 works, and the feeding clamping block 2521 on the clamping assembly 252 moves relatively to clamp the pipe 100, and then the moving drive device 258 works to move the pipe 100 clamped by the clamping assembly 252, leaving the material rack 210 and placing it at the specified position, and the feeding is completed.

[0087] It can be understood that after completing one loading, the mobile drive device 258 works and returns to the original position, the clamping drive device 253 drives, the clamping assembly 252 moves relatively and loosens a certain distance, and the lifting drive device 257 works and the clamping assembly 252 descends on the loading base 251, waiting for the next time to clamp the pipe 100.

[0088] The automatic pipe feeding device 200 is provided with a flip structure 220 which can separate the pipes 100 individually, level them through a leveling structure 240, and finally feed them through a feeding structure 250. The feeding of the pipes 100 is fully automated, which improves efficiency and reduces labor intensity. After the pipes 100 are separated individually, they are leveled so that the pipes 100 can reach a predetermined position immediately when being fed, so that the feeding is accurate and material consumption is reduced.

[0089] Automatic pipe cutting device 300

[0090] The automatic pipe cutting device 300 is arranged on one side of the automatic pipe feeding device 200, and mainly includes a cutting machine 310 and a pipe feeding mechanism 320. The pipe 100 is fed to the pipe feeding mechanism 320 through the automatic pipe feeding device 200. The pipe feeding mechanism 320 can feed the pipe 100 to the cutting machine 310 to a predetermined length. When the pipe 100 reaches a predetermined length in the cutting machine 310, the cutting machine 310 cuts the pipe 100 so that the pipe 100 can be of a predetermined length for subsequent use.

[0091] refer to Figures 8 to 10The pipe delivery mechanism 320 includes a supporting structure 321 and a pipe delivery structure 322. The supporting structure 321 is used to support the pipe 100 loaded by the automatic pipe loading device 200. The pipe delivery structure 322 can move the pipe 100 supported on the supporting structure 321, and is used to transport the pipe 100 on the supporting structure 321 into the cutting machine 310 so that the pipe 100 is cut by the cutting machine 310.

[0092] The pipe delivery structure 322 includes a pipe delivery frame 3221 and a pipe clamping assembly 3223 that can move on the pipe delivery frame 3221. When the pipe 100 is located on the pipe delivery structure 322, the pipe 100 is clamped by the pipe clamping assembly 3223 and the pipe 100 is moved, so that the pipe 100 can be completely delivered into the cutting machine 310. Specifically, in this embodiment, the tube delivery rack 3221 is arranged along the first direction, and is provided with a third guide rail 32211 and a rack 32212 arranged along the first direction. The tube clamping assembly 3223 can be moved on the tube delivery rack 3221 along the first direction by being installed on the third guide rail 32211, and a tube delivery driving device 3222 is provided on the tube clamping assembly 3223. Preferably, the tube delivery driving device 3222 is a servo driving motor, and a gear is provided on the driving end of the tube delivery driving device 3222. When the tube clamping assembly 3223 is installed on the third guide rail 32211, the gear is engaged with the rack 32212, and is driven by the tube delivery driving device 3222. The gear rotates on the gear, so that the tube clamping assembly 3223 can move on the tube delivery rack 3221 along the first direction to deliver the pipe 100 into the cutting machine 310.

[0093] The tube clamping assembly 3223 includes a tube delivery base 32231, a tube clamping block 32232 movably arranged on the tube delivery base 32231, and a tube clamping driving device 32236. The tube delivery base 32231 is provided with a fourth guide rail 32233 arranged along a third direction. Two tube clamping blocks 32232 are provided. The two tube clamping blocks 32232 are both movably mounted on the fourth guide rail 32233 on the tube delivery base 32231 and are arranged relatively to each other along the third direction. The tube delivery base 32231 is also provided with a rotatable second meshing tooth 32235, and the two tube clamping blocks 32232 are both provided with a rack. When the two tube clamping blocks 32232 are relatively arranged on the tube delivery base 32231, the second meshing tooth 32235 is arranged between the two tube clamping blocks 32232, and the racks of the two tube clamping blocks 32232 are both meshed with the second meshing tooth 32235. The driving end of the tube clamping drive device 32236 is connected to one of the tube clamping blocks 32232. When one of the tube clamping blocks 32232 is driven to move, the second meshing tooth 32235 is driven to rotate, and the other tube clamping block 32232 is driven to move through the second meshing tooth 32235. Preferably, the two tube clamping blocks 32232 are arranged to move relative to each other, so that the tube clamping assembly 3223 can clamp or loosen the pipeline 100 through the tube clamping block 32232.

[0094] Furthermore, the pipe clamp block 32232 is a roughly V-shaped structure, so that when it is relatively arranged, it can clamp pipes 100 of different specifications. And the pipe clamp block 32232 of the V-shaped structure is also provided with a plurality of teeth 32232a to ensure that the pipe clamp block 32232 can clamp the pipe 100.

[0095] The supporting structure 321 is installed on the pipe delivery rack 3221 and can be raised and lowered. When the automatic pipe feeding device 200 is feeding, the pipe clamping assembly 3223 clamps the pipe 100 above the supporting structure 321, and the supporting structure 321 is raised and lowered to support the pipe 100. Specifically, in this embodiment, the supporting structure 321 includes a supporting driving device 3211, a lifting slide 3212, and a supporting member 3213 arranged on the lifting slide 3212. The lifting slide 3212 is provided with a fifth guide rail 3215, and the pipe delivery rack 3221 is provided with a slider. The lifting slide 3212 is installed on the slider through the fifth guide rail 3215 and can be raised and lowered on the pipe delivery rack 3221. A through hole 32213 is also provided on the pipe delivery rack 3221 at a position corresponding to the lifting slide 3212. The supporting driving device 3211 is installed on the pipe delivery rack 3221, and its driving end is connected to the lifting slide 3212. The lifting slide 3212 can be raised and lowered on the pipe delivery rack 3221 by driving the supporting driving device 3211. The supporting member 3213 can extend to the top of the pipe delivery rack 3221 on the through hole 32213 to support the tube 100.

[0096] Furthermore, the supporting member 3213 is a substantially V-shaped structure. Specifically, in the present embodiment, the supporting member 3213 includes a first roller 3213 and a second roller 3214, which are cross-arranged on the lifting slide 3212 to form a substantially V-shaped structure for supporting the pipe 100. Preferably, the angle formed between the first roller 3213 and the second roller 3214 is 120 degrees, so that the supporting member 3213 can more simply and effectively support pipes 100 of different specifications, and the pipe 100 can move on the supporting structure 321 formed by the first roller 3213 and the second roller 3214 without damaging the pipe 100.

[0097] refer to Figure 8 , Fig.11 The cutting machine 310 is arranged at one end of the pipe feeding mechanism 320, that is, the cutting machine 310 is located at one end of the pipe feeding mechanism 320 in the first direction, so that the pipe feeding mechanism 320 can feed the pipe 100 into the cutting machine 310 for cutting.

[0098] refer to Fig.11The cutting machine 310 includes a whole machine frame 311, a clamping assembly 313 arranged on the whole machine frame 311, and a cutting structure 316 that can be raised and lowered on the whole machine frame 311 for cutting. The pipe delivery mechanism 320 delivers the pipe 100 to the cutting machine 310. When the pipe 100 is delivered to a predetermined length, it is clamped by the clamping assembly 313, and then the pipe 100 is cut to obtain a pipe 100 of a predetermined length.

[0099] The whole machine frame 311 is provided with a track 312 for installing a cutting structure 316. The cutting structure 316 is installed on the track 312 of the whole machine frame 311 and can be driven to move, and is used to approach or move away from the pipeline 100 to achieve cutting of the pipeline 100. Specifically, in this embodiment, the whole machine frame 311 is provided with a track 312 arranged along the third direction at the top, and the cutting structure 316 is movably installed on the track, and can be driven by a driving device such as a motor, a cylinder, etc. to move along the second direction on the whole machine frame 311, so that the cutting structure 316 can cut the pipeline 100 on the whole machine frame 311.

[0100] The cutting structure 316 includes a cutting drive device 3161 and a cutting knife 3162 driven by the cutting drive device 3161 for cutting. Preferably, the cutting drive device 3161 and the cutting knife 3162 can be connected by a belt drive. When in use, the cutting drive device 3161 drives the cutting knife 3162 to rotate for cutting, and the cutting structure 316 is driven to move (lift and lower) along the second direction on the whole machine frame 311 to the position where the pipeline 100 is located, and the pipeline 100 can be cut.

[0101] The clamping assembly 313 includes at least one group of clamping blocks 3131 for clamping the pipe 100 and at least one clamping driving device 3132 for driving the clamping blocks 3131 to clamp the pipe 100. When the pipe 100 extends to a predetermined length of the whole machine frame 311, the clamping driving device 3132 drives the clamping blocks 3131 to clamp the pipe 100, and then cuts the pipe 100 through the cutting structure 316. Specifically, in this embodiment, there are two groups of clamping blocks 3131, and two clamping driving devices 3132 are provided, preferably driving cylinders. Each group of clamping blocks 3131 includes two relative clamping blocks 3131. The driving ends of the two clamping driving devices 3132 are respectively connected to one clamping block 3131 in the two groups of clamping blocks 3131. By driving one of the clamping blocks 3131 in one group to move, the distance between the two clamping blocks 3131 in one group of clamping blocks 3131 is reduced, and the pipe 100 is clamped.

[0102] Moreover, on the cutting machine 310, the position of the clamping assembly 313 corresponds to the position of the pipe delivery structure 322. When the pipe delivery structure 32 is feeding, the pipe 100 can pass between the two sets of clamping blocks 3131, and the two sets of clamping blocks 3131 can be driven by the clamping drive device 3132 to clamp the pipe 100 passing through them.

[0103] Furthermore, the cutting blade 3162 on the cutting structure 316 on the whole machine frame 311 is arranged along the third direction. The cutting blade 3162 is a circular saw blade. When cutting, the cutting blade 3162 performs a circular saw longitudinal cut on the pipe 100, so that the cutting machine 310 can be used to cut pipes 100 of different specifications. When the cutting structure 316 is driven to move on the whole machine frame 311, the cutting blade 3162 faces the gap between the two sets of clamping blocks 3131. When the cutting structure 316 moves, the cutting blade 3162 can move between the two sets of clamping blocks 3131 to cut the pipe 100.

[0104] Furthermore, the clamping drive device 3132 can also be adjusted on the whole machine frame 311, so that the opening amount of each group of clamping blocks 3131 can be adjusted. Specifically, in this embodiment, the whole machine frame 311 is provided with a mounting member 314 for mounting the clamping drive device 3132, the clamping drive device 3132 is mounted on the mounting member 314 and can move, and the clamping blocks 3131 connected to the driving end of the clamping drive device 3132 can also move with the clamping drive device 3132. The whole machine frame 311 is also provided with an adjustment handle 315, the adjustment handle 315 is mounted on the mounting member 314 and can rotate and move, preferably, one end of the adjustment handle 315 is set as a screw, which can rotate and move on the mounting member 314 through threaded engagement, and the other end is a handle portion that can be manually rotated. When the adjusting handle 315 is installed on the mounting component 314, one end of the screw rod is also connected to the clamping drive device 3132. By rotating the handle portion of the adjusting handle 315, the adjusting handle 315 is rotated on the mounting component 314, thereby driving the clamping drive device 3132 to move on the mounting component 314, so as to adjust the opening amount of each group of clamping blocks 3131.

[0105] When the feeding structure 250 is working, the pipe 100 is moved above the pipe delivery mechanism 320 in the third direction, and the supporting structure 321 is raised and lowered to support the pipe 100. At this time, the feeding structure 250 moves, no longer clamps the pipe 100, and retracts to the bottom of the material rack 210.

[0106] At the same time, the pipe clamping assembly 323 of the pipe feeding mechanism 320 works to clamp the pipe 100 , and the pipe clamping assembly 323 moves on the pipe feeding mechanism 320 to feed the pipe 100 into the cutting machine 310 to a predetermined length.

[0107] After the pipe delivery mechanism 320 delivers the pipe 100 to a predetermined length, the clamping assembly 313 on the cutting machine 310 clamps the pipe 100, the pipe clamping assembly 323 releases the pipe 100, and the cutting structure 316 moves on the whole machine frame 311 to cut the pipe 100.

[0108] The automatic pipe cutting device 300 is provided with a pipe delivery mechanism 320 to automatically deliver the pipe 100 to a predetermined length, and the cutting of the pipe 100 is fully automated, which improves efficiency and reduces labor intensity. Moreover, the supporting structure 321 and the clamping assembly 313 can both support and clamp pipes 100 of different specifications, and the automatic pipe cutting device 300 can be used for different pipes 100, and has strong applicability.

[0109] Pipeline automatic storage device 400

[0110] refer to Figures 12 to 17 The automatic pipeline storage device 400 is arranged on the outlet side of the cutting machine 310, and mainly includes a conveying mechanism 410 for transporting the pipeline 100 cut by the cutting machine 310 and a storage mechanism 420 for storing the pipeline 100. Part of the conveying mechanism 410 is arranged on the outlet side of the cutting machine 310, and the other part is arranged above the storage mechanism 420. After the cutting machine 310 cuts the pipeline 100, the conveying mechanism 410 transports the cut pipeline 100 to the storage mechanism 420 for storage.

[0111] refer to Fig.13 The conveying mechanism 410 includes a conveying frame 411 and a pipeline conveying structure 412 that is movable on the conveying frame 411. The pipeline 100 is clamped by the pipeline conveying structure 412 and then conveyed to the storage mechanism 420. Specifically, in this embodiment, the conveying frame 411 is a rectangular parallelepiped frame, one end of which is arranged at the outlet of the cutting machine 310, and the conveying frame 411 is partially located above the storage mechanism 420. A track 4111 is arranged on the top of the conveying frame 411. The pipeline conveying structure 412 includes a moving seat 4121 and a clamping plate 4122 that is arranged on the moving seat 4121 and is used to clamp the pipeline 100. The moving seat 4121 is movably mounted on the track 4111 and can be driven by a motor to move on the conveying frame 411. The clamping plate 4122 can be driven to move relatively to clamp the pipeline 100, and convey it to the top of the storage mechanism 420, and then put it into the storage mechanism 420 for storage.

[0112] Furthermore, at least two groups of fixed clamping blocks 4123 are arranged on the clamping plate 4122 of the pipeline conveying structure 412 to ensure the stability of the pipeline 100 when clamped. Preferably, the fixed clamping blocks 4123 of the clamping plate 4122 are provided with four groups, each group includes two fixed clamping blocks 4123 respectively arranged on two clamping plates 4122, and four groups of fixed clamping blocks 4123 are arranged on two clamping plates 4122 along the length direction. The clamping plate 4122 can be driven to move relatively, so that the four groups of fixed clamping blocks 4123 on it clamp the pipeline 100, convey it to the top of the storage mechanism 420, and put it into the storage mechanism 420 for storage. The pipeline conveying structure 412 is provided with multiple groups of fixed clamping blocks 4123 for clamping, which can maintain the stability of clamping the pipeline 100.

[0113] The storage mechanism 420 includes a storage rack 421, a single-flip structure 422 arranged on the storage rack 421, and a branching structure 423 arranged on the storage rack 421. After the conveying mechanism 410 conveys the pipeline 100 to the top of the storage rack 421, the conveying mechanism 410 puts down the pipeline 100, and the pipeline 100 is branched by the branching structure 423, so that the pipeline 100 falls on different sides of the storage rack 421, and the pipeline 100 on different sides of the storage rack 421 is separately separated by the single-flip structure 422, so as to facilitate the use of the pipeline 100 in the next process.

[0114] refer to Fig.14 The storage rack 421 is provided with a plurality of branch welding plates 4211, which are arranged in an array on the left and right sides of the storage rack 421 in the third direction, so that the storage rack 421 has two left and right storage spaces 4212 in the third direction.

[0115] Furthermore, an anti-falling protrusion 4213 is provided at the end of the branch welding plate 4211. When the branch welding plate 4211 is installed on the storage rack 421 and the array is distributed on the left and right sides of the storage rack 421, the branch welding plate 4211 will set one end with the anti-falling protrusion 4213 on the side of the storage rack 421, that is, the outer sides of the two storage spaces 4212 on the left and right sides of the storage rack 421 have anti-falling protrusions 4213 for limiting, so as to prevent the pipe 100 from rolling down on the storage rack 421.

[0116] The branching structure 423 is disposed on the storage rack 421 and is located in the middle of the storage rack 421 in the third direction. It corresponds to the position of the conveying mechanism 410, or more precisely, is located below the conveying mechanism 410. When the conveying mechanism 410 conveys the pipe 100 to the top of the storage rack 421, the branching structure 423 can divide the pipe 100 into two left and right storage spaces 4212 on the storage rack 421 in the third direction. Specifically, in this embodiment, refer to Fig.14 and Fig.17The branching structure 423 includes a branching member 4231 rotatably mounted on the storage rack 421 for branching and a branching driving device 4232 for driving the branching member 4231 to rotate. The branching member 4231 includes a rotating portion 42311 rotatably mounted on the storage rack 421 and a guiding portion 42312 for guiding the movement of the pipeline 100. The guiding portion 42312 is connected to one end of the rotating portion 42311, and the top of the guiding portion 42312 is set as an arc structure 42312a. The branch driving device 4232 is connected to the other end of the rotating part 42311. When the branch driving device 4232 is driven, the rotating part 42311 rotates in the middle position of the storage rack 421, so that the arc structure 42312a of the guide part 42312 connected thereto can swing back and forth to both sides in the third direction, thereby dividing the pipeline 100 into two storage spaces 4212 composed of the branch welding plates 4211 on the storage rack 421, thereby realizing branching on the storage rack 421.

[0117] Furthermore, in order to maintain the stability of the pipeline 100 during movement and branching, multiple branching components 4231 are provided on the storage rack 421 along the first direction. The multiple branching components 4231 are connected by shafts and driven to rotate by the same branching driving device 4232, so that the movement of the pipeline 100 is more stable.

[0118] refer to Fig.14 and Fig.15 The single-turn structure 422 is arranged on both sides of the storage rack 421 in the third direction, and the pipes 100 in the left and right storage spaces 4212 on the storage rack 421 can be turned over and separated separately to facilitate loading in the next process.

[0119] The left and right storage spaces 4212 on the storage rack 421 are both provided with a single-flip structure 422, and the single-flip structure 422 includes a dial-turn piece 4221 installed on the branch welding plate 4211, a partition protrusion 4222 arranged on the branch welding plate 4211 and a single-flip driving device 4223. The partition protrusion 4222 divides the two storage spaces 4212 on the storage rack 421 into two smaller spaces in the third direction. The dial-turn piece 4221 is connected to the driving end of the single-flip driving device 4223. Driven by the single-flip driving device 4223, the dial-turn piece 4221 flips the pipe 100 in the two smaller spaces to achieve individual separation of the pipe 100. Specifically, in the present embodiment, the partition protrusion 4222 divides the left and right storage spaces 4212 on the storage rack 421 in the third direction into a temporary storage space 4212a for temporarily storing the pipe 100 and a preparation space 4212b for preparing for feeding, wherein the preparation space 4212b is located between the partition protrusion 4222 and the anti-fall-off protrusion 4213. When the pipe 100 is fed through the conveying mechanism 410, it will first be divided into the temporary storage space 4212a of the left storage space 4212 of the storage rack 421 or the temporary storage space 4212a of the right storage space 4212 of the storage rack 421 through the branch structure 423. When the next process is required to load the material, the single-flip driving device 4223 drives the dial 4221 to flip the pipe 100 from the temporary storage space 4212a to the preparation space 4212b alone to wait for the next process.

[0120] Preferably, in order to maintain the stability of the pipeline 100 when it is flipped, a plurality of rotating parts 4221 are also provided on the storage rack 421 along the first direction. The rotating parts 4221 on the same side of the storage rack 421 are all connected by an axis and driven to flip by the same single-flip driving device 4223, so that the flipping of the pipeline 100 is more stable.

[0121] When the cutting machine 310 is cutting, the cut part of the pipe 100 extends out from the outlet of the cutting machine 310, and the pipe conveying structure 412 of the conveying mechanism 410 clamps the extended part of the pipe 100. After the cutting machine 310 completes the cutting, the clamping assembly 313 is released, and the pipe conveying structure 412 clamps the pipe and sends the pipe 100 to the top of the storage mechanism 420.

[0122] Then, the pipeline conveying structure 412 discharges the material on the storage rack 421 of the storage mechanism 420 , and the pipeline 100 falls on the branching structure 423 and is divided by the branching structure 423 into a temporary storage space 4212a of one of the storage spaces 4212 on the left and right sides of the storage rack 421 .

[0123] The single-turn structure 422 of the storage mechanism 420 can also turn the pipeline 100 from the temporary storage space 4212a to the preparation space 4212b to prepare for the next process.

[0124] The automatic pipe storage device 400 is provided with a pipe conveying structure 412, and the pipe 100 can be clamped after cutting and conveyed to the storage mechanism 420 for storage, which improves efficiency and reduces labor intensity. The storage mechanism 420 is provided with a branching structure 423 and a single-turning structure 422, and the pipe 100 is automatically divided and placed on the storage rack 421, and is automatically separated to prepare for the next process, with a high degree of automation and intelligence.

[0128] The material taking mechanism 510 includes a material taking frame 511 and a material taking structure 512 that can be driven to move and lift on the material taking frame 511. The material taking structure 512 is driven to clamp the pipe 100 on the storage rack 421 and move it to the material discharging mechanism 520 to complete the threading loading process. Specifically, in this embodiment, the material taking frame 511 is arranged on one side of the automatic pipe storage device 400, and the material taking frame 511 is at least partially located above the storage rack 421. Preferably, the material taking frame 511 is partially located above the single flip structure 422. The material taking structure 512 is a clamping assembly 5121 that can move and lift on the material taking frame 511. For example, a track along the third direction and the second direction is arranged. By being driven to move on the track, the material taking structure 512 is moved and lifted on the material taking frame 511, and the pipe 100 is clamped by the clamping assembly 5121 to the storage rack 421, thereby clamping the pipe 100. Preferably, the clamping assembly 5121 can be a common pipe clamping structure on the market.

The pipe 100 is placed on the roller group 523. The roller driving device 522 can drive the roller group 523 to rotate, so that the pipe 100 placed thereon can be moved to the threading machine 530 for threading. Specifically, in this embodiment, a plurality of roller groups 523 are provided on the material discharging base 521 along the third direction, each roller group 523 includes a plurality of rollers 5231 arranged along the first direction, and the outer circumferential surface of each roller 5231 is set to be roughly concave V-shaped, which can be used to support pipes 100 of different specifications. Each roller 5231 is provided with a gear on the side, and a sprocket can be provided at the driving end of the roller driving device 522 to be connected with the gear of the roller through a chain, thereby driving the roller 5231 to roll and realize the movement of the pipeline 100. The pipeline 100 falls on a group of roller groups 523 along the first direction, and the roller driving device 522 can move the pipeline 100 in the length direction.

[0130] The threading machine 530 is arranged at one end of the feeding mechanism 520, and is used for feeding and threading the pipe 100 on the feeding mechanism 520.

[0131] Furthermore, the plurality of rollers 5231 in the same group on the discharge base 521 are all driven by the same roller driving device 522. Specifically, the plurality of rollers 5231 in the same group are all connected to the roller driving device 522 by the same chain, so that the rollers 5231 in the same group have the same rolling speed, thereby preventing the pipeline 100 from being damaged when moving on the roller group 523.

[0132] When in use, the material taking mechanism 510 clamps the pipe 100 in the preparation space 4212b of the storage rack 421, moves the pipe 100 to the roller group 523, drives the roller driving device 522 to move the pipe 100 on the roller group 523, and sends it to the threading machine 530 for threading.
