[0064] As shown in FIG. 1, a pipe processing method comprises the following steps: Figure 19

[0065] S1: The pipe 20 is placed in the hole processing equipment 1, and the hole processing equipment 1 processes a hole on the pipe 20;

[0066] S2: The material conveying device 3 conveys the pipe 20 from the hole processing equipment 1 to the notch processing equipment 2;

[0067] S3: The notch processing equipment 2 processes a notch on the pipe 20.

[0068] After the pipe 20 is processed with a hole on the hole processing equipment 1, the pipe 20 can be conveyed to the notch processing equipment 2 for notch processing by the material conveying device 3. The pipe 20 is conveyed by the material conveying device 3, which is beneficial to improve the conveying efficiency, thereby improving the processing efficiency of the pipe 20, and reducing the probability of damage to the pipe 20, which is beneficial to reduce the production cost.

[0069] ​When the previous pipe 20 is in step S3, the next pipe 20 can be in step S1 at the same time, so as to further improve the processing efficiency of the pipe 20.

[0070] In some embodiments, step S1 comprises:

[0071] S11: the first pipe clamping device 11 clamps the pipe 20;

[0072] S12: the first hole processing structure 121 processes the first hole 201 on the lower side wall of the pipe 20;

[0073] S13: the second hole processing structure 122 processes the second hole 202 on the front side wall and the rear side wall of the pipe 20;

[0074] S14: the third hole processing structure 123 processes the third hole 203 on the upper side wall of the pipe 20.

[0075] In this embodiment, the pipe 20 is clamped on the first pipe clamping device 11, and the pipe 20 can be processed with three kinds of holes, which is beneficial to save clamping time and improve processing quality and efficiency.

[0076] In other embodiments, when the pipe 20 is clamped on the first pipe clamping device 11, the pipe 20 can be processed with one, two, four or more kinds of holes.

[0077] In some embodiments, steps S12, S13 and S14 are performed synchronously.

[0078] In this embodiment, the three kinds of holes are processed synchronously, which is beneficial to improve the rationality of the time arrangement of each hole processing procedure, improve the hole processing efficiency, and thus improve the pipe 20 processing efficiency.

[0079] In other embodiments, the three kinds of holes are processed in a sequential order.

[0080] In other embodiments, two of the three kinds of holes are processed synchronously.

[0081] In some embodiments, in steps S12, S13 and S14, the first hole processing structure 121, the second hole processing structure 122 and the third hole processing structure 123 respectively process the first hole 201, the second hole 202 and the third hole 203 on the pipe 20 by milling.

[0082] The hole processing is performed by milling, which is beneficial to improve the hole processing precision and improve the product quality.

[0083] In some embodiments, the first hole processing structure 121, the second hole processing structure 122 and the third hole processing structure 123 are processed by means of drilling.

[0084] In some embodiments, the step S2 comprises the following steps:

[0085] S21: the first material conveying clamping structure 321 conveys the pipe 20 from the hole processing equipment 1 to the intermediate support seat 33;

[0086] S22: the second material conveying clamping structure 322 conveys the pipe 20 from the intermediate support seat 33 to the notch processing equipment 2.

[0087] In this way, the single movement distance of the pipe 20 during the conveying process is shortened, and the probability of damage to the pipe 20 is reduced, especially for pipes 20 with small diameters and long lengths, and the protective effect is more obvious.

[0088] In this embodiment, the first material conveying clamping structure 321 and the second material conveying clamping structure 322 move synchronously. When the first material conveying clamping structure 321 conveys the previous pipe 20 from the hole processing equipment 1 to the intermediate support seat 33, the second material conveying clamping structure 322 conveys the next pipe 20 from the intermediate support seat 33 to the notch processing equipment 2, which helps to improve the conveying efficiency of the pipe 20.

[0089] In some embodiments, the step S3 comprises the following steps:

[0090] S31: the second pipe clamping device 21 clamps the pipe 20;

[0091] S32: the notch processing driving device 224 drives the first cutting knife 2213 to move and process a V-shaped notch 204 on the pipe 20;

[0092] S33: the notch processing driving device 224 drives the second cutting knife 2223 to move and processes a second notch 205 on the pipe 20;

[0093] The step S32 and the step S33 are performed synchronously.

[0094] In this way, the notch processing equipment 2 can process multiple notches on the pipe 20 at the same time, which helps to improve the processing efficiency.

[0095] In some embodiments, the pipe processing method further comprises the step S4: the polishing device polishes the pipe on the notch processing equipment; the step S3 and the step S4 are performed synchronously.

[0096] The notch processing and the polishing are simultaneously performed, no additional damage is caused to the pipe 20, the processing time of each process can be more reasonably distributed, the pipe 20 processing time can be further shortened, and the processing efficiency is improved.

[0097] In some other embodiments, the step S4 is performed first, and then the step S3 is performed, so as to avoid damaging the pipe 20 with reduced strength after the notch processing.

[0098] In some specific embodiments, before the step S1, there is a step S5: the feeding and lifting assembly 52 lifts the pipe 20 into the hole processing equipment 1; and the feeding and lifting assembly 52 positions the pipe 20 when the hole processing equipment 1 processes the hole of the pipe 20.

[0099] After the feeding and lifting assembly 52 lifts the pipe 20 to the corresponding position of the hole processing equipment 1, the pipe 20 is still supported and horizontally and radially positioned during the hole processing. Therefore, the feeding and lifting assembly 52 can be regarded as a part of the first pipe clamping device 11, so that the feeding and lifting assembly 52 is diversified in function, and the pipe 20 can be more fully supported during the hole processing, and meanwhile, the structure of the hole processing equipment 1 and the feeding device 5 is more compact.

[0100] In some specific embodiments, the pipe processing method further comprises a step S6: the discharging and lifting assembly 62 lifts the pipe 20 to be separated from the second pipe clamping device 21, so that the pipe 20 moves along the discharging inclined table 612 and falls onto the discharging conveying assembly 62.

[0101] The embodiment also discloses a pipe processing equipment for performing the above pipe processing method, referring to Figures 1 to 18 , comprising the hole processing equipment 1 and the notch processing equipment 2; the hole processing equipment 1 comprises the first pipe clamping device 11 and the hole processing device 12 corresponding in position, when the pipe 20 is clamped on the first pipe clamping device 11, the hole processing device 12 can process a hole on the pipe 20; the notch processing equipment 2 comprises the second pipe clamping device 21 and the notch processing device 22 corresponding in position, when the pipe 20 is clamped on the second pipe clamping device 21, the notch processing device 22 can process a notch on the pipe 20; the pipe processing equipment further comprises the conveying device 3 arranged between the hole processing equipment 1 and the notch processing equipment 2, the conveying device 3 comprises the conveying and clamping device 32 and the conveying moving device 31 connected in transmission, and is used for conveying the pipe 20 on the first pipe clamping device 11 to the second pipe clamping device 21.

[0102] After the hole is processed on the first pipe clamping device 11, the pipe 20 can be conveyed to the second pipe clamping device 21 by the conveying device 3 for notching. The pipe 20 is transported by the conveying device 3, which is beneficial to improve the conveying efficiency, thereby improving the pipe 20 processing efficiency, reducing the probability of pipe 20 damage, and reducing the production cost.

[0103] In some embodiments, referring to Figures 7 to 9 The conveying clamping device 32 includes at least two conveying clamping structures, and the two conveying clamping structures are drivingly connected to the conveying moving device 31.

The conveying horizontal moving cylinder 312 can drive the first conveying clamp cylinder and the second conveying clamp cylinder to move synchronously along the arrangement direction thereof. The plurality of conveying longitudinal moving cylinders 311 and the plurality of conveying horizontal moving cylinders 312 also move synchronously.

[0105] Referring to Figure 8 and Figure 9, the first time, under the driving of the material moving device 31, the first material clamping structure 321 clamps and moves the pipe 20 on the first clamping device to the intermediate support seat 33, and the second material clamping structure 322 is empty; in the subsequent multiple material moving processes, under the driving of the material moving device 31, the second material clamping structure 322 clamps and moves the pipe 20 on the intermediate support seat 33 to the second pipe clamping device 21, and at the same time, the first material clamping structure 321 clamps and moves the pipe 20 on the first clamping device to the intermediate support seat 33; the last time, under the driving of the material moving device 31, the second material clamping structure 322 clamps and moves the pipe 20 on the intermediate support seat 33 to the second pipe clamping device 21, and the first material clamping structure 321 is empty.

During machining, the pipe 20 is located on the first cutting die 2212 and the second pipe clamping device 21, the notch machining driving device 224 first drives the first cutting knife 2213 to move downward and extend into the pipe 20, and then drives the first cutting knife 2213 to move in the horizontal direction perpendicular to the pipe 20, so as to machine a V-shaped notch 204 on the pipe 20.

[0136] Through the first gap processing structure 221, the V-shaped gap 204 is processed on the pipe 20, so that the pipe 20 can be bent at the V-shaped gap 204, and after bending, the two edges of the V-shaped gap 204 are welded on one side to form an angular strip-shaped pipe, enriching the product variety.

[0140] During processing, the pipe 20 is clamped on a plurality of second pipe clamp cylinders, and simultaneously passes through the first cutting accommodation groove 22122 on the first cutting die 2212, and then the first hydraulic cylinder 22111 drives the second hydraulic cylinder 22112 and the first cutting knife 2213 to move downward, so that the first cutting knife 2213 penetrates the upper side wall of the pipe 20, and stops when the lowermost end of the V-shaped blade 22131 of the first cutting knife 2213 is about to contact the lower side wall of the pipe 20, and finally the second hydraulic cylinder 22112 drives the first cutting knife 2213 to move forward and backward to cut V-shaped notches on the front and rear side walls of the pipe 20 respectively, completing the processing of the V-shaped gap 204.

[0147] In some embodiments, referring to Figure 10 and Figure 12The notch processing device 22 comprises a notch processing driving device 224 and a second notch processing structure 222, the second notch processing structure 222 comprises two second cutting dies 2222 and two second cutting knives 2223 arranged one by one, the second cutting knives 2223 are drivingly connected to the notch processing driving device 224 and located on the upper side of the second cutting dies 2222, during processing, the pipe 20 is located on the second cutting dies 2222 and the second pipe clamping device 21, the notch processing driving device 224 first drives the second cutting knives 2223 to move downward, and then drives the second cutting knives 2223 to move along the horizontal direction perpendicular to the pipe 20, so as to process the second notch 205 on the end of the pipe 20.

[0148] Specifically, the second cutting knives 2223 are arranged on the second hydraulic cylinders 22112 of the notch processing driving device 224.

During processing, the pipe 20 is clamped on the plurality of second pipe clamp cylinders and passes through the second cutting accommodation grooves 22221 on the second cutting dies 2222. Then the first hydraulic cylinders 22111 drive the second hydraulic cylinders 22112 and the second cutting knives 2223 to move downward, and stop when the lowermost end of the second cutting knives 2223 is about to contact the upper side wall of the pipe 20. Finally, the second hydraulic cylinders 22112 drive the first cutting knives 2213 to move forward and backward, so as to process the second notch 205 on the end of the extension plate 206.

The polishing machine 42 is used for polishing the burrs protruding outward around the second hole 202 on the rear side wall of the pipe 20.

[0153] The polishing device 4 is arranged beside the second pipe clamping device 21, so that the polishing device 4 can polish the pipe 20 while the notching processing equipment 2 processes the pipe 20. Since the structural strength of the pipe 20 is reduced after the notching, in the prior art, the pipe 20 is polished first after the hole processing, and then notched. In the embodiment, the notching and polishing are performed simultaneously, which does not cause additional damage to the pipe 20, and is also beneficial to more reasonably allocate the processing time of each process, further shorten the processing time of the pipe 20, and improve the processing efficiency.

[0155] Specifically, the feeding conveying assembly 51 comprises a feeding conveying frame and a feeding conveying belt arranged thereon, and the feeding and lifting assembly 52 comprises a feeding and lifting cylinder and a feeding and lifting clamp cylinder arranged thereon, which is beneficial to improve the stability of feeding.
