These terms are only used to distinguish elements of the same type from each other. For example, without departing from the scope of this disclosure, the first element may also be referred to as the second element, and similarly, the second element may also be referred to as the first element.

[0035] Refer to Figures 1 to 12 , in some embodiments, the present invention discloses an automatic pipe cutting device, including:

[0036] Refer to Figure 1 the frame 1000 of

[0037] Refer to Figure 1 Combined with Figures 2 to 4 the pipe body feeding mechanism 2000 of Figure 1 Combined with Figures 2 to 3 , the pipe body feeding hopper 2100 is vertically arranged on the frame 1000, a feeding port 2110 is opened at the top end of the pipe body feeding hopper 2100, and a discharging port 2120 is horizontally opened at the bottom end of the pipe body feeding hopper 2100. Refer to Figure 1 Combined with Figure 13 As shown in

[0038] Refer to Figure 1 Combined with Figures 2 to 3 , a pushing component 2200 and a supporting component 2500 are respectively arranged on both sides corresponding to the discharging port 2120.

[0039] Refer to Figures 2 to 3 , the pushing end of the pushing component 2200 is arranged towards one end of the discharging port 2120, the supporting part of the supporting component 2500 is adjacently arranged at the other end of the discharging port 2120, and the blocking block 2300 is arranged between the discharging port 2120 and the supporting part of the supporting component 2500. Refer to Figure 2, the pusher component 2200 can push the metal tube at the bottom of the feeding hopper 2100 to be processed out from the discharge port 2120 to the top of the supporting part of the supporting component 2500. When the metal tube is pushed out at the discharge port 2120, the metal tube will hit the material blocking block 2300, so as to force the metal tube to flip over from the material blocking block 2300 under the restricting action of the protruding material blocking block. At this time, the flat part in the middle of the metal tube is supported by the supporting part of the supporting component 2500, so that the flat part in the middle of the metal tube can be parallel to the horizontal plane. Wait for the metal tube on the supporting part of the supporting component 2500 by the previous supporting component to be conveyed by the feeding mechanism 3000 of the metal tube; at the same time, the material blocking block 2300 also has the function of blocking the metal tube. After the previous metal tube is conveyed away from the supporting component 2500, the material blocking block 2300 blocks the metal tube at the bottom of the tube body feeding hopper 2100 and waits for the pusher component 2200 to push out the metal tube.

[0040] Continue to refer to Figure 1 , the feeding mechanism 3000 arranged on the corresponding side of the supporting component 2500, the feeding mechanism 3000 is arranged on the frame 1000, and the pushing end of the feeding mechanism 3000 is arranged towards the top of the supporting component 2500. Refer to the figure in combination with Figure 5 , the pushing end of the feeding mechanism 3000 sleevs the metal tube on the supporting part of the supporting component 2500 and drives it to the next clamping mechanism.

[0041] Refer to Figure 1 In combination with Figure 7 , the clamping mechanism 4000 arranged on the corresponding other side of the supporting component 2500, the clamping path of the clamping mechanism 4000 is arranged corresponding to the pushing end of the feeding mechanism 3000, and the cutting groove 4900 with an inclined trend at the top of the clamping mechanism 4000. After the metal tube to be processed is clamped in the clamping path of the clamping mechanism 4000, the cutting mechanism is ready to cut the metal tube.

[0042] Refer to Figure 1 the cutting mechanism 5000, the cutting mechanism 5000 is arranged on the frame 1000, the cutting part of the cutting mechanism 5000 is arranged corresponding to the cutting groove 4900, and the cutting mechanism 5000 cuts the metal tube obliquely, so that the metal tube is cut into two finished metal tubes as shown in the appendix Figure 14 , and then the clamping mechanism 4000 releases the two finished metal tubes, completing the operations of automatic feeding, feeding, clamping and cutting of the metal tube.

[0043] In the above-mentioned automatic pipe cutting device, the metal pipe to be processed is automatically fed through the metal pipe feeding mechanism. Through the cooperation of the discharge port on the metal pipe feeding hopper, the material blocking block, the pushing component and the supporting component, during the process of the flat middle part of the metal pipe being conveyed from feeding to the feeding part, the flat middle part of the metal pipe remains parallel to the horizontal plane. At the same time, the end of the pusher of the feeding mechanism is tightly sleeved with the opening of the metal pipe, ensuring that the flat middle part of the fed metal pipe remains parallel to the horizontal plane. After the feeding mechanism conveys the metal pipe to the clamping mechanism, it can also ensure that the flat part of the metal pipe in the clamping mechanism is parallel to the horizontal plane. Only in this way can the two cut metal pipes ensure the output of two-section metal pipe finished products with high-precision inclined cutting, ensuring the high-precision operation of the automatic cutting of metal pipe finished products.

[0044] The entire automatic pipe cutting device realizes the fully automatic production of feeding, feeding and clamping, improving the production efficiency of metal pipes.

[0045] Refer to Figures 2 to 4 As shown in the figure, the pusher assembly 2200 includes a pusher cylinder 2210 and a pusher block 2220 connected to the push rod of the pusher cylinder 2210. When the pusher block 2220 pushes the metal pipe to be processed out of the discharge port 2210, convex portions 2221 are provided at both ends of the pusher block 2220. The provision of the convex portions 2221 on the pusher block 2220 can reduce the contact area with the metal pipe, thereby reducing the friction between the pusher block 2220 and the metal pipe, enabling the metal pipe to be turned over the material blocking block 2300 with a small pushing force, and also reducing the excessive friction between the metal pipe and the material blocking block 2300 due to a large pushing force, which may scratch the metal pipe. The pusher block 2220 pushes the metal pipe to be processed out of the discharge port 2120.

[0046] Refer to Figure 4 As shown in the figure, the outer contour shape of the inner bottom plate surface of the pipe body feeding hopper 2100 partially matches the outer contour shape of the pipe body. The inner bottom plate surface of the pipe body feeding hopper 2100 in the figure is arc-shaped, which matches the arc shape of the two sides of the metal pipe, making it easier for the pusher block 2220 to roll the metal pipe when pushing.

[0047] Refer to 2 to Figure 4, the tube feeding mechanism 2000 includes a stop material cylinder 2600. The push rod of the stop material cylinder 2600 is connected to one end of a stop block 2300. The stop material cylinder 2600 is fixed below the tube feeding hopper 2100. The stop block 2300 moves up and down at the other end of the discharge port 2120. The inner shape of the stop block 2300 partially matches the outer contour shape of the metal tube. The stop material cylinder 2600 can drive the stop block 2300 to move slightly up and down, which is used in combination with metal tubes of different sizes. Different sizes of metal tubes can be adjusted to roll under the stop block 2300 with different protruding degrees. It is also possible to adjust the stop material cylinder 2600 to drive the stop block 2300 to extend upward for a longer length to achieve the additional function of blocking the metal tube at the discharge port 2120. Refer to Figure 4 The inclined plane shape of the stop block 2300 is adapted to the outer contour shape of the arc of the metal tube. Therefore, the inner inclined plane of the stop plate and the inner bottom plate arc of the tube feeding hopper 2100 cooperate with the pusher block 2220 having a protruding portion 2221, which can make it easier for the pusher block 2220 to push the metal tube to roll over the stop block 2300, and make the flat part of the metal tube lie flat on the material supporting assembly 2500.

[0048] Refer to Figure 1 Combined with Figures 7 to 9 As shown, the feeding mechanism 3000 includes a first feeding cylinder 3100, a second feeding cylinder 3200, a feeding slide rail assembly 3300, a feeding mounting seat 3400, a feeding ejector rod 3500 and a connecting block 3600.

[0049] Refer to Figures 7 to 9As shown, the first feeding cylinder 3100 is installed at the end of the feeding mounting base 3400. The slide rail of the feeding slide rail assembly 3300 is arranged on the feeding mounting base 3400. The second feeding cylinder 3200 is installed on a slider of the feeding slide rail assembly 3300. The end of the feeding ejector rod 3500 is installed on another slider of the slide rail assembly through the connecting block 3600 assembly. The push rod of the second feeding cylinder 3200 is fixedly connected with the connecting block 3600 assembly. The push rod of the first feeding cylinder 3100 is fixedly connected with the rear part of the second feeding cylinder 3200, so as to allow the first feeding cylinder 3100 to push the second feeding cylinder 3200 and the feeding ejector rod 3500 to move on the feeding slide rail assembly 3300. The shape of the starting end of the feeding ejector rod 3500 matches the shape of the opening of the metal pipe. The above feeding mechanism realizes two-stage feeding and pushing. When the metal pipe is placed on the material supporting assembly 2500, first, the second feeding cylinder 3200 acts first. After the starting end of the feeding ejector rod 3500 is pushed into the opening of the metal pipe and tightened, the first feeding cylinder 3100 then acts to send the metal pipe on the feeding ejector rod 3500 to the next clamping mechanism. The feeding ejector rod 3500 configured by the first feeding cylinder 3100 and the second feeding cylinder 3200 displaces on the feeding slide rail assembly 3300 through the connecting block 3600, ensuring the stability of the linear movement of the feeding ejector rod 3500. Moreover, the action stroke of the first feeding cylinder 3100 is greater than that of the second feeding cylinder 3200.

[0050] Referring to Figure 5 Combined with Figure 6 , the feeding mechanism 3000 includes a feeding adjustment cylinder 3700 and a plurality of feeding adjustment slide rail assemblies 3800.

[0051] Referring to Figure 6 As shown, the slide rails of the plurality of feeding adjustment slide rail assemblies 3800 are arranged in parallel on the frame 1000. Figure 6 In the embodiment of

[0052] Referring to Figure 7 Combined with Figure 9As shown, the clamping mechanism 4000 includes a clamping cylinder 410, a clamping mounting part 420, a clamping side mounting plate 430, a first clamping block 440, a second clamping block 450, a first material discharging strip 460, a second material discharging strip 470, a first connecting rod 480 and a second connecting rod 490. The cutting grooves 4900 are distributed on the tops of the first clamping block 440 and the second clamping block 450.

[0053] Continue to refer to Figure 7 Combined with Figure 9 As shown, the clamping cylinder 410 is arranged on the side plate outside the clamping mounting part 420, and the push rod of the clamping cylinder 410 is fixedly connected to the outer side part of the first clamping block 440.

[0054] Refer to Figure 7 Combined with Figure 8 As shown, one end of the first connecting rod 480 is fixedly connected to the side plate outside the clamping mounting part 420, and the other end is fixedly connected to the inner side surface of the second clamping block 450. The first clamping block 440 is slidably connected to the first connecting rod 480 through a sliding hole.

[0055] Refer to Figure 7 Combined with Figure 8 As shown, one end of the second connecting rod 490 is fixedly connected to the inner side surface of the first clamping block 440, and the other end is fixedly connected to the clamping side mounting plate 430 arranged adjacent to the outside of the second clamping block 450. The second clamping block 450 is slidably connected to the second connecting rod 490 through a sliding hole, so as to allow the clamping cylinder 410 to drive the first clamping block 440 and the second clamping block 450 to clamp or loosen the metal pipe respectively.

[0056] Refer to Figure 7 Combined with Figure 8 As shown, the push rod of the clamping cylinder 410 is fixedly connected to one end of the first material discharging strip 460 through a connecting piece. The other end of the first material discharging strip 460 is arranged through the first clamping block 440. One end of the second material discharging strip 470 is fixedly connected to the inner wall of the clamping side mounting plate 430, and the other end is arranged through the second clamping block 450, so as to allow the first material discharging strip 460 and the second material discharging strip 470 to push the completed metal pipes to fall respectively when the first clamping block 440 and the second clamping block 450 loosen the two cut sections of the metal pipe.

[0057] The above-mentioned clamping mechanism 4000 controls the action of the clamping cylinder 410. When the push rod of the clamping cylinder 410 extends, the first clamping block 440 slides on the first connecting rod 480, causing the first clamping block 440 to gradually approach the second clamping block 450. The cooperation of the two clamping blocks enables the clamping of the metal pipe. At the same time, the ends of the first ejector bar 460 and the second ejector bar 470 respectively retract into the first clamping block 440 and the second clamping block 450. At this time, the pusher block does not push the completed two sections of the metal pipe for feeding. When the push rod of the clamping cylinder 410 retracts, the first clamping block 440 slides on the first connecting rod 480, causing the first clamping block 440 to gradually move away from the second clamping block 450. The cooperation of the two clamping blocks enables the loosening of the metal pipe. At the same time, the ends of the first ejector bar 460 and the second ejector bar 470 respectively extend from the inner sides of the first clamping block 440 and the second clamping block 450, as Figure 7 shown. At this time, the ejector bar pushes the completed two sections of the metal pipe for feeding to carry out ejection. The above-mentioned clamping mechanism 4000 realizes the function of auxiliary ejection while clamping or loosening the metal pipe, effectively improving the efficiency of ejection. At the same time, a limiting component 4999 can be provided at the end of the clamping channel between the first clamping block 440 and the second clamping block 450. The front end surface of the limiting component 4999 can adopt a soft material, enabling the metal pipe to reach the front end surface of the limiting component 4999 to play a limiting role, so that the electric saw component 5400 can accurately cut the flat position in the middle of the metal pipe.

[0058] Referring to Figures 7 to 9 , the clamping mechanism 4000 includes an ejection cylinder 4100 and an ejection block 4200. The push rod of the ejection cylinder 4100 is fixedly connected to the pusher block 2220. The ejection cylinder 4100 is installed on the outer side of the clamping installation part 420. The ejection cylinder 4100 and the clamping cylinder 410 are arranged perpendicular to each other. When the first ejector bar 460 and the second ejector bar 470 respectively push the completed metal pipe to fall from the first clamping block 440 and the second clamping block 450, the ejection block 4200 ejects the completed metal pipe. The further cooperation of the ejection cylinder 4100 and the ejection block 4200 further improves the degree of automatic production of the device.

[0059] Referring to Figures 10 to 11The cutting mechanism 5000 includes a mounting column 510, a driving rail assembly 520 vertically arranged on the mounting column 510, a lead screw 530 arranged in the mounting column 510, and an electric saw assembly 5400 slidably connected to the driving rail assembly 520. A driving motor 511 is installed on the top of the mounting column 510. The power end of the driving motor 511 is connected to one end of the lead screw 530. The lead screw 530 is in transmission connection with the side of the electric saw assembly 5400 to allow the lead screw to drive the electric saw assembly 5400 to move up and down on the driving rail assembly 520. The above-mentioned electric saw assembly 5400 can control the relative position of the electric saw assembly 5400 moving up and down according to whether there is a metal pipe to be processed on the cutting groove 4900. After the cutting is completed, the cutting assembly moves up from the mounting column 510 to wait for the next workpiece to be processed.

[0060] Reference Figure 10 The electric saw assembly 5400 includes an electric saw motor 5410, a saw blade 5420 connected to the electric saw motor 5410 through a transmission part, a protective shell 5430, a cooling water pipe 5440, and a switch 5450 for controlling the cooling water pipe 5440. The outer upper part of the electric saw blade 5420 covers the protective shell 5430. The switch 5450 is arranged above the protective shell 5430. The interface of the switch 5450 is connected with one end of a pair of cooling water pipes 5440. The other end of the cooling water pipe 5440 passes through the side wall of the protective shell 5430. The other end of the cooling water pipe 5440 opens toward the outer surface of the saw blade 5420. The cooling water pipe is arranged here to cool the two sides of the electric saw blade with water, so that the electric saw assembly can cooperate with the device for automatic production for a long time while ensuring the life of the saw blade.

[0061] Reference Figure 9 The clamping mechanism 4000 includes an adjusting base 4800, an adjusting bolt 4810 connected to the bottom of the adjusting base 4800, and a fastening nut 4820, and the clamping mounting portion 420 is mounted on the adjusting base 4800. A mounting hole is provided on the frame 1000. The adjusting bolt 4810 passes through the mounting hole, and the adjusting bolt 4810 part at the bottom of the frame 1000 is threadedly connected with the fastening nut 4820, so that the adjusting base 4800 is fastened to the frame 1000, and the fastening nut 4820 is connected with an adjusting long rod 4821. It is convenient for the operator to adjust the tightness of the fastening nut 4820 by adjusting the long rod, so as to facilitate the adjustment of the deflection position of the clamping mechanism 4000 on the frame 1000, so as to meet various production requirements.

[0062] Reference Figure 2As shown in the figure, the stock supporting assembly 2500 includes a stock supporting cylinder 2510, a supporting plate 2520 and a limiting block 2530. The stock supporting cylinder 2510 is vertically and adjacently arranged on the frame 1000 at the discharge port 2120. The upper end of the push rod of the stock supporting cylinder 2510 is fixedly connected to the supporting plate 2520. The width of the supporting plate 2520 is less than or equal to the size of the flat part in the middle of the metal pipe. The supporting plate 2520 is fixedly connected to the inner side surface of the limiting block 2530 through a connecting pipe 2400. There is a gap between the supporting plate 2520 and the limiting block 2530. A convex part 2521 is arranged upward on one side of the surface of the supporting plate 2520 away from the discharge port 2120. When the metal pipe to be processed rolls over onto the supporting plate 2520, since the width of the supporting plate 2520 is less than or equal to the size of the flat part in the middle of the metal pipe, the flat part in the middle of the supporting plate 2520 can ensure that it is placed on the supporting plate 2520. At the same time, since the limiting block 2530 can cooperate with the feeding ejector rod 3500, one end of the metal pipe is restricted at the limiting block 2530. The feeding ejector rod 3500 can extend into and tightly fit the metal pipe from the opening at the other end of the metal pipe body. At the same time, the convex part 2521 enables the metal pipe body to be at an accurate position and be tightly fitted by the action of the feeding ejector rod 3500.

[0063] Overall, the working principle of the above automatic pipe cutting device is as follows: After the metal pipe to be processed is placed into the pipe body feeding hopper 2100, the pushing cylinder 2210 acts to roll the metal pipe from the discharge port 2120 over the baffle block 2300 onto the supporting plate 2520. The second feeding cylinder 3200 drives the feeding ejector rod 3500 to extend into and tightly fit the metal pipe from the opening of the metal pipe body. The stock supporting cylinder 2510 retracts, and the first feeding cylinder 3100 extends to drive the metal pipe to the clamping mechanism. The clamping cylinder 410 drives the first clamping block 440 and the second clamping block 450 to clamp the metal pipe body. The first feeding cylinder 3100 and the second feeding cylinder 3200 drive and act to retract, so that the feeding ejector rod 3500 releases the metal pipe. The driving motor 511 on the cutting mechanism 5000 drives the lead screw 530, so that the saw blade 5420 on the electric saw assembly 5400 drops into the cutting groove 4900 to obliquely cut the metal pipe. After completion, the saw blade 5420 is raised, and the first clamping block 440 and the second clamping block 450 release the two completed sections of the metal pipe, completing the automated cutting operation of one workpiece.
