[0050] A pipe punching device using an auxiliary device includes a frame 5, a punching plate 6, a punching device 1, a cutting device 2, and a conveying device 3. The top surface spacer of the frame 5 is equipped with at least two guide rails 51 extending in the front-to-back direction, and also includes an auxiliary device 4.

[0051] The auxiliary device 4 is mounted in front of the punching plate 6; the auxiliary device 4 includes a first mounting base 41, a first clamping device 42 and a second clamping device 43;

[0052] The conveying device 3 includes a second mounting base 31, a driving motor 32 and a connecting rod 34;

[0053] The first mounting base 41 and the second mounting base 31 are slidably mounted on the guide rail 51 , respectively. The drive motor 32 drives the second mounting base 31 to slide along the guide rail 51 , and the rear end of the connecting rod 34 is connected to the second mounting base 31 .

[0054] The first clamping device 42 and the second clamping device 43 are respectively mounted on the first mounting base 41 . The first clamping device 42 clamps the front end of the connecting rod 34 , and the second clamping device 43 is used to clamp the front end of the pipe 10 to be processed which is a tailing.

[0055] Figure 1-5 This is a schematic structural diagram of the pipe punching equipment using the auxiliary device of the present invention. Figure 1 A schematic structural diagram of a pipe punching device for using an auxiliary device 4 to complete the punching process of a pipe 10 to be processed as tailings.

[0056] like Figure 2-5As shown, the punching plate 6 is installed near the front end of the frame 5, the cutting device 2 and the punching device 1 are adjacently mounted on the punching plate 6, the conveying device 3 is mounted on the guide rail 51, the conveying device 3 is located behind the punching device 1, and the third clamping device 33 is installed on the second mounting base 31. The rear end of the pipe 10 to be processed is clamped in the third clamping device 33. When the drive motor 32 is started, the drive motor 32 drives the second mounting base 31 to slide forward along the guide rail 51, so that the front end of the pipe 10 to be processed passes through the first punching die 11 and the second punching die 11 in the punching device 1 in sequence. After the hole die 12 completes the punching process, it moves forward through the feeding hole 211 of the cutting die 21 of the cutting device 2. The cutting die 21 cuts off the front end portion of the pipe 10 to be processed that has completed the punching process according to the set punching step length. After punching processes with multiple punching steps, the front end face of the second mounting base plate 31 is close to the rear end face of the punching flat plate 6. At this time, the remaining pipe 10 to be processed becomes the tail material, which means that the rear end of the pipe 10 to be processed that is clamped as the tail material by the third clamping device 33 cannot continue to complete the punching process of the tail material portion of the pipe 10 to be processed.

[0057] like Figure 1 As shown, the pipe punching device using the auxiliary device of the present invention, when the pipe 10 to be processed becomes the tail material, the driving motor 32 is turned off, the clamping of the rear end of the pipe 10 to be processed by the third clamping device 33 is released, and the driving motor 32 is moved backward along the guide rail 51 to a distance the same as the length of the pipe 10 to be processed, and then the front end of the connecting plate 34 is clamped on the first clamping device 42, so that the first clamping device 42 is connected to the second mounting base 31, and the front end of the pipe 10 to be processed that is the tail material is pushed forward and passes through the punching device 1 and the cutting device 2 in sequence, and then the front end of the pipe 10 to be processed that is the tail material is clamped by the second clamping device 43. , then start the drive motor 32, and drive the first mounting base 41 and the second mounting base 31 to slide forward along the guide rail 51 at the same time through the drive motor 32, the connecting plate 34 and the first clamping device 42, thereby driving the rear end of the tailing portion of the pipe 10 to be processed to pass through the first punching die 11 and the second punching die 12 in sequence, and then completing the punching processing of the tailing portion of the pipe 10 to be processed, and finally cutting off the remaining part of the rear end portion of the pipe 10 to be processed by the cutting device 2, that is, completing the punching processing of the tailing portion of the pipe 10 to be processed, thereby improving the raw material utilization rate of the pipe 10 to be processed and avoiding the increase in pipe processing costs due to waste of raw materials.

[0058] Furthermore, the first clamping device 42 includes a first hydraulic cylinder 421 and a first support frame 422; the second clamping device 43 includes a second hydraulic cylinder 431 and a second support frame 432;

[0059] The first support frame 422 and the second support frame 432 are respectively mounted on the top surface of the first mounting base plate 41.

[0060] The output end of the first hydraulic cylinder 421 extends downward into the first support frame 422 and is close to the top surface of the first mounting base 41 ; the output end of the second hydraulic cylinder 431 extends downward into the second support frame 432 and is close to the top surface of the first mounting base 41 .

[0061] like Figure 3 As shown, the front end of the connecting rod 34 is clamped downward on the top surface of the first mounting base plate 41 through the output end of the first hydraulic cylinder 421, and the front end of the pipe 10 to be processed, which is the tail material, is clamped downward on the top surface of the first mounting base plate 41 through the output end of the second hydraulic cylinder 431.

[0062] Furthermore, the auxiliary device 4 also includes a mounting frame 40 and a baffle 45;

[0063] The rear end surface of the mounting bracket 40 is fixed to the front end surface of the frame 5, and the top surface of the mounting bracket 40 is flush with the top surface of the frame 5;

[0064] At least two guide rails 51 are mounted on the top surface of the mounting frame 40 at intervals. The front ends of the guide rails 51 are close to the front end surface of the mounting frame 40. The first mounting base 41 is slidably mounted on the two guide rails 51.

[0065] The lower end of the baffle 45 is fixed to the front end surface of the mounting frame 40 , the upper end of the baffle 45 protrudes upward, and the upper end surface of the baffle 45 is located above the top surface of the first mounting base 41 ; the baffle 45 is located between the two guide rails 51 .

[0066] like Figure 1 and Figure 2 As shown, the baffle 45 can prevent the first mounting base 41 from exceeding the front ends of the two guide rails 51 , thereby preventing the first mounting base 41 from falling from the front of the mounting bracket 40 .

[0067] Furthermore, the auxiliary device 4 further includes a locking assembly 44;

[0068] The locking assembly 44 includes a flap cylinder 441 and a flap 442;

[0069] The lower end of the flap cylinder 441 is fixed to the mounting bracket 40, the upper end of the flap cylinder 441 extends obliquely upward, one end of the flap 442 is rotatably fixed to the upper end of the flap cylinder 441, and the other end of the flap 442 is used to press the front end surface of the first mounting base plate 41 by flipping and facing upward.

[0070] like Figure 2 As shown, when the front end of the connecting rod 34 is clamped downward on the top surface of the first mounting base plate 41 through the output end of the first hydraulic cylinder 421, in order to prevent the first mounting base plate 41 from moving forward along the guide rail 51 during the clamping process, the other end of the flap 442 can be flipped upward so that the rear end face of the other end of the flip 442 after flipping is pressed against the front end face of the first mounting base plate 41, and the rear end face of the pressed first mounting base plate 41 is pressed against the front end face of the punching plate 6, thereby improving the operational convenience of clamping the front end of the connecting rod 34.

[0071] After completing the clamping operation of the front end of the connecting rod 34 and before processing the tailings, the other end of the flap 442 is flipped downward to prevent the flap 442 from blocking the first mounting base 41 from moving forward.

[0072] Furthermore, the auxiliary device 4 further includes a first supporting plate 47 and a second supporting plate 48;

[0073] A third supporting plate 52 is also mounted on the upper portion of the frame 5;

[0074] The cutting device 2 includes a cutting die 21, and the cutting die 21 is provided with a feeding through hole 211;

[0075] The bottom surface of the cutting die 21 abuts against the top surface of the punching plate 6, and the feeding hole 211 passes through the cutting die 21 from front to back. The feeding hole 211 is used to accommodate the front end of the pipe 10 to be processed.

[0076] The first supporting plate 47, the second supporting plate 48 and the third supporting plate 52 extend in the front-to-back direction respectively and are located on the same horizontal line;

[0077] The second supporting plate 48 is disposed in the first supporting frame 422 and is located directly below the output end of the first hydraulic cylinder 421;

[0078] The first supporting plate 47 is disposed directly in front of the second supporting plate 48 , and the bottom surface of the first supporting plate 47 is fixed to the top surface of the mounting frame 40 ;

[0079] The bottom surface of the third supporting plate 52 is fixed to the top surface of the frame 5, the rear end of the third supporting plate 52 passes under the second mounting base 31 and is close to the rear end surface of the frame 5, and the front end of the third supporting plate 52 is close to the rear end surface of the punching plate 6.

[0080] like Figure 1-5As shown, the bottom of the pipe 10 to be processed can be supported by the first support plate 47, the second support plate 4 or the third support plate 52 during the entire processing process, thereby having good stability and helping to improve the processing quality of the pipe 10 to be processed.

[0081] Furthermore, the frame 1 is also equipped with a discharge slide 7;

[0082] The unloading chute 7 is arranged below the punching plate 6 .

[0083] Figure 2 A discharge chute 7 for collecting punching waste is also provided below the auxiliary device 4 , and the mounting frame 40 is located on the right side of the discharge chute 7 .

[0084] Therefore, when the auxiliary device 4 is in a non-use state, the first mounting base plate 41 can also be fixed by the flap 442 to prevent the first mounting base plate 41 from sliding, thereby improving the operational convenience of taking the cut pipe from above the first support plate 47 and preventing the auxiliary device 4 from colliding when taking the cut pipe.

[0085] Furthermore, the conveying device 3 further includes a third clamping device 33;

[0089] The output end of the third hydraulic cylinder 331 extends downward into the third support frame 332 and is close to the top surface of the second mounting base 31 .

[0090] like Figure 2 and Figure 5 As shown, the front end of the non-tailing pipe 10 to be processed is clamped downward on the top surface of the second mounting base plate 31 through the output end of the third hydraulic cylinder 331, so that the front end of the pipe 10 to be processed passes through the first punching die 11 and the second punching die 12 in the punching device 1 in sequence. After the punching process is completed, the front end of the processed pipe 10 passes forward through the feeding hole 211 of the cutting die 21 of the cutting device 2. The cutting die 21 cuts off the front end of the pipe 10 to be processed according to the set cutting step length. In this way, the punching process of the front end part of the pipe 10 to be processed before becoming the tailing can be completed through the punching process of multiple punching steps.

[0091] Furthermore, the conveying device 3 further includes a rack plate 35;

[0092] The rack plate 35 extending in the front-to-back direction is close to the right side of the third supporting plate 52, and the rack plate 35 is fixed to the top surface of the frame 5;

[0093] A driving gear is installed at the output end of the driving motor 32, and the driving gear is engaged with the rack plate 35. The rear end of the rack plate 35 passes under the second mounting base plate 31 and is close to the rear end surface of the frame 5. The front end of the rack plate 35 is close to the rear end surface of the punching plate 6.

[0094] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, by cooperating with the rack plate 35 and the driving gear located at the output end of the driving motor 32, the stability of the driving motor 32 in driving the second mounting base plate 31 to slide back and forth can be improved, and the vibration of the second mounting base plate 31 can be reduced, thereby improving the processing quality of the pipe 10 to be processed.

[0095] Preferably, the first hydraulic cylinder 421 , the second hydraulic cylinder 431 and the third hydraulic cylinder 331 are all gas-liquid booster cylinders.

[0096] The gas-liquid booster cylinder combines the advantages of air cylinders and oil cylinders, with the advantages of fast action speed, stable pneumatic transmission, high output pressure, low energy consumption and small space occupation, and also has the characteristics of low noise, no temperature rise and long service life.

[0097] In summary, if Figure 1-5 In the embodiment of the present invention shown, the pipe punching equipment using the auxiliary device can improve the raw material utilization rate of the pipe 10 to be processed through the cooperation of the auxiliary device 4 and the conveying device 3, and avoid the increase in pipe processing costs due to waste of raw materials.
