Description

Technical Field

[0001] The present invention relates to the technical field of pipe processing, and in particular to a pipe processing method and equipment. Background Art

[0002] Pipes are widely used in today's production and life, and the specific application scenarios are also diverse. In different application scenarios, the processing requirements for pipes will also be different. For example, the pipes used to make the cabinet door panel frame need to be processed with three kinds of holes on the pipes, and then bent to form the three sides of the frame. In order to make the bending process smooth, two notches will be processed on the pipes during processing for avoidance during bending.

[0003] In the prior art, the processing process of this type of pipe is as follows: a certain length of pipe is cut out, and then the pipe is clamped and positioned two or three times. After each clamping and positioning, the hole processing device processes one or two holes on the pipe, and finally three holes are processed on the pipe; then the pipe is polished, and after polishing, the pipe is clamped and positioned again, and the notch processing device processes a notch on the pipe to complete the processing of the pipe.

[0004] However, the above prior art has at least the following deficiencies:

[0005] 1. A pipe has to go through multiple processes in the process of completing the above processing. Even if the processing processes do not interfere with each other, different processes must be carried out separately. The time coordination between the processes is not reasonable, which is not conducive to improving processing efficiency;

[0006] 2. A pipe has to go through multiple processing devices during the above processing, so it needs to be clamped and positioned multiple times, which takes a lot of time, and the position accuracy of each hole and notch cannot be effectively guaranteed;

[0007] 3. The transfer of workpieces between different processing devices relies on manual handling, which is not only inefficient but also prone to collisions and damage to the workpieces. Summary of the invention

[0064] like Fig.19 As shown, a pipe processing method comprises the following steps:

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

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

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

[0068] After the hole is processed in the pipe 20 on the hole processing equipment 1, it can be transported to the notch processing equipment 2 through the material transport device 3 for notch processing. Using the material transport device 3 to transport the pipe 20 is beneficial to improving the transportation efficiency, thereby improving the processing efficiency of the pipe 20, and can also reduce the probability of damage to the pipe 20, which is beneficial to reducing production costs.

[0069] When the pipes 20 are processed in batches, when the previous pipe 20 is processed to step S3 , the next pipe 20 can be processed to step S1 simultaneously, so as to further improve the processing efficiency of the pipes 20 .

[0070] In some specific embodiments, step S1 includes:

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

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

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

[0075] In this embodiment, by clamping the pipe 20 on the first pipe clamping device 11, three types of holes can be processed on the pipe 20, which is beneficial to saving clamping time and improving processing quality and efficiency.

[0076] In some other embodiments, when the tube 20 is clamped on the first tube clamping device 11 , one, two, four or more types of holes may be processed on the tube 20 .

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

[0078] In this embodiment, the processing of the three holes is performed simultaneously, which is beneficial to improving the rationality of the time arrangement of each hole processing step, improving the hole processing efficiency, and thus improving the efficiency of the tube 20 processing.

[0079] In some other embodiments, the three types of holes are processed sequentially.

[0080] In some other embodiments, two of the three types of holes are processed simultaneously.

[0081] In some specific 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 tube 20 by milling.

[0082] Hole processing by milling is beneficial to improving the accuracy of hole processing and improving the quality of finished products.

[0083] In some other embodiments, the first hole processing structure 121 , the second hole processing structure 122 and the third hole processing structure 123 are processed into holes by drilling with a twist drill.

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

[0085] S21: The first material transporting and clamping structure 321 transports the pipe 20 from the hole processing device 1 to the intermediate supporting seat 33:

[0086] S22 : The second material transporting and clamping structure 322 transports the pipe 20 from the intermediate supporting seat 33 to the notch processing equipment 2 .

[0087] Such a configuration is beneficial to shortening the single moving distance of the pipe 20 during the material transportation process and reducing the probability of damage to the pipe 20, especially for the pipe 20 with a smaller diameter and a longer length, the protective effect is more obvious.

[0088] In this embodiment, the first material transport clamping structure 321 and the second material transport clamping structure 322 move synchronously. When the first material transport clamping structure 321 transports the previous pipe 20 from the hole processing equipment 1 to the intermediate supporting seat 33, the second material transport clamping structure 322 transports the next pipe 20 from the intermediate supporting seat 33 to the notch processing equipment 2, which is beneficial to improving the transportation efficiency of the pipe 20.

[0089] In some specific embodiments, step S3 includes 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 processes a V-shaped notch 204 on the tube 20;

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

[0093] Step S32 and step S33 are performed simultaneously.

[0094] Such an arrangement enables the notch processing device 2 to process multiple notches on the pipe 20 at the same time, which is beneficial to improving the processing efficiency.

[0095] In some specific embodiments, the tube processing method further includes step S4: a grinding device grinds the tube on the notch processing equipment: step S3 and step S4 are performed simultaneously.

[0096] The notch processing and grinding are carried out simultaneously, which will not cause additional damage to the pipe 20, and is also conducive to more reasonable allocation of the processing time of each process, which is conducive to further shortening the processing time of the pipe 20 and improving the processing efficiency.

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

[0098] In some specific embodiments, there is a step S5 before step S1: the loading and pushing assembly 52 pushes the tube 20 into the hole processing equipment 1; when the hole processing equipment 1 performs hole processing on the tube 20, the loading and pushing assembly 52 positions the tube 20.

[0099] After the material loading and lifting component 52 lifts the pipe 20 to the corresponding position of the hole processing device 1, the pipe 20 is still supported and horizontally radially positioned during the hole processing. Therefore, the material loading and lifting component 52 can be regarded as a part of the first pipe clamping device 11, so that the material loading and lifting component 52 has diversified functions, and the pipe 20 can be more fully supported during the hole processing, which is also conducive to making the hole processing device 1 and the material loading device 5 more compact.

[0100] In some specific embodiments, the tube processing method further includes step S6: the material unloading and lifting assembly 62 lifts the tube 20 to disengage from the second tube clamping device 21 , so that the tube 20 moves along the unloading ramp 612 and falls onto the unloading conveying assembly 62 .

[0101] This embodiment also discloses a pipe processing device for executing the pipe processing method. Figures 1 to 18 , including a hole processing device 1 and a notch processing device 2; the hole processing device 1 includes a first pipe clamping device 11 and a hole processing device 12 corresponding to the position, when the first pipe clamping device 11 is clamped with a pipe 20, the hole processing device 12 can process a hole on the pipe 20; the notch processing device 2 includes a second pipe clamping device 21 and a notch processing device 22 corresponding to the position, when the second pipe clamping device 21 is clamped with a pipe 20, the notch processing device 22 can process a notch on the pipe 20; the pipe processing equipment also includes a material transport device 3 arranged between the hole processing device 1 and the notch processing device 2, the material transport device 3 includes a material transport clamping device 32 and a material transport moving device 31 connected by transmission, which is used to transport the pipe 20 on the first pipe clamping device 11 to the second pipe clamping device 21.

[0102] After the holes are processed on the first tube clamping device 11, the tube 20 can be transported to the second tube clamping device 21 through the material transporting device 3 for notch processing. Transporting the tube 20 with the material transporting device 3 is beneficial to improving the transportation efficiency, thereby improving the efficiency of tube 20 processing, and can also reduce the probability of damage to the tube 20, which is beneficial to reducing production costs.

[0103] In some specific embodiments, reference Figures 7 to 9 The material transport clamping device 32 includes at least two material transport clamping structures, and the two material transport clamping structures are both transmission-connected to the material transport moving device 31; the material transport device 3 also includes an intermediate supporting seat 33 arranged between the first pipe clamping device 11 and the second pipe clamping device 21, and the two material transport clamping structures are respectively a first material transport clamping structure 321 and a second material transport clamping structure 322.

[0105] refer to Figure 8 and Fig. 9During the first material transportation, driven by the material transportation moving device 31, the first material transportation clamping structure 321 clamps the pipe 20 on the first clamping device and moves it to the intermediate supporting seat 33, and the second material transportation clamping structure 322 is unloaded; in the subsequent multiple material transportation processes, driven by the material transportation moving device 31, the second material transportation clamping structure 322 clamps the pipe 20 on the intermediate supporting seat 33 and moves it to the second pipe clamping device 21, and synchronously, the first material transportation clamping structure 321 clamps the pipe 20 on the first clamping device and moves it to the intermediate supporting seat 33; during the last material transportation, driven by the material transportation moving device 31, the second material transportation clamping structure 322 clamps the pipe 20 on the intermediate supporting seat 33 and moves it to the second pipe clamping device 21, and the first material transportation clamping structure 321 is unloaded.

[0106] Such a setting is conducive to shortening the single moving distance of the pipe 20 during the material transportation process and reducing the probability of damage to the pipe 20, especially for the pipe 20 with a smaller diameter and a longer length, the protective effect is more obvious; it is also conducive to shortening the length of the material transportation moving device 31, thereby reducing the length, volume and footprint of the pipe processing equipment, making the pipe processing equipment compact and easy to install.

[0107] Furthermore, the intermediate supporting seat 33 is an intermediate clamp cylinder, which is beneficial to maintaining the position accuracy of the pipe 20 during transportation and improving transportation efficiency.

[0112] The first limiting part 1131 is in the shape of a four-sided cone. When clamping, the first limiting driving device 1121 drives the first limiting member 113 to move along the axial direction of the tube 20 and approach the tube 20, so that the first limiting part 1131 extends from the end opening of the tube 20 until the four conical surfaces of the first limiting part 1131 are respectively pressed on the four side edges of the end opening of the tube 20, thereby achieving radial limiting of the tube 20. The two first tube clamping structures 111 clamp the tube 20 from both ends of the tube 20, thereby achieving axial limiting of the tube 20, that is, limiting in the left and right directions.

[0113] The second limiting portion 11421 includes a limiting groove arranged on the lower side of the second limiting piece 1142, and the structure of the limiting groove matches the shape of the tube 20. After the first limiting structure 115 clamps the tube 20, the second limiting movable structure 1141 drives the second limiting piece 1142 to move downward, so that the limiting groove is sleeved on the tube 20, thereby limiting the tube 20 in the front and rear directions.

[0114] The first position limiting driving device 1121 and the second position limiting moving structure 1141 both adopt cylinder structures.

[0115] In this way, the first limiting structure 115 and the second limiting structure 114 are structurally integrated, which is beneficial to saving space and improving the utilization rate of the pipe processing equipment.

[0116] The first pipe clamping device 11 in this embodiment can perform all-round positioning of the pipe 20. It is more targeted especially for square pipes, and can achieve accurate positioning of the square pipes, thereby improving processing accuracy.

[0117] Furthermore, the second position-limiting member 1142 can be detachably connected to the second position-limiting movable structure 1141, so that it is convenient to replace the appropriate second position-limiting member 1142 according to the pipes 20 of different shapes, which is beneficial to expanding the application scope of the pipe processing equipment.

[0118] In some specific embodiments, reference Figure 1 and Figure 3 The hole processing device 12 includes a first hole processing structure 121, a second hole processing structure 122 and a third hole processing structure 123 which are staggered in position. The first hole processing structure 121 is located at the lower side or upper side of the first pipe clamping device 11, the second hole processing structure 122 is located at the front side or rear side of the first pipe clamping device 11, and the third hole processing structure 123 is located at the upper side or lower side of the first pipe clamping device 11.

Since the positions of the first hole processing structure 121, the second hole processing structure 122 and the third hole processing structure 123 are interlaced, during processing, the first hole processing structure 121, the second hole processing structure 122 and the third hole processing structure 123 can process the tube 20 at the same time, so as to process the first hole 201, the second hole 202 and the third hole 203 on the tube 20. Such an arrangement allows the pipe 20 to be processed into three holes of different specifications after one clamping, which is beneficial to saving the time consumed in clamping the pipe 20, improving the accuracy of the positions of each hole and the mutual matching relationship, improving product quality, and also beneficial to improving the rationality of the time arrangement of each hole processing process, improving the hole processing efficiency, thereby improving the efficiency of the pipe 20 processing.

The first hole 201 is used to install a latch, the second hole 202 is used to install a handle, and the third hole 203 is used to install a card plate to clamp the door panel of the cabinet door to the inner side of the cabinet door frame.

[0122] In some other specific embodiments, the positions of the various hole processing structures do not have to be interlaced with each other, and the multiple hole processing structures can sequentially process holes of different specifications on the tube 20 .

[0123] In some specific embodiments, reference Figure 3 The first hole processing structure 121 includes a first hole processing driving device 1211 and a first puncher 1212 disposed thereon. The first hole processing driving device 1211 is disposed at the lower side of the first position-limiting movable seat 1122. The first puncher 1212 is located inside the first position-limiting movable seat 1122 and at the lower side of the first position-limiting member 113. After the first tube clamping structure 111 clamps the tube 20, the first hole processing driving device 1211 drives the first puncher 1212 to move upward close to the end of the tube 20, and processes the first hole 201 on the lower side wall of the end of the tube 20. The first hole processing structure 121 is disposed on both first position-limiting movable seats 1122. The first hole processing driving device 1211 adopts a cylinder structure.

[0124] Specifically, the first punching machine 1212 includes a first milling cutter, which processes the first hole 201 by milling.

[0125] When processing the first hole 201, the first punch 1212 processes from bottom to top, and the second limiting structure 114 can limit the upward movement of the tube 20, which is beneficial to keep the position of the tube stable during processing and improve the processing quality.

[0126] Such an arrangement is conducive to structural integration of the first tube clamping structure 111 and the first hole processing structure 121, and further improves the rationality of the spatial distribution of various components of the tube processing equipment.

[0127] In some other embodiments, the first punching machine 1212 includes a first twist drill, which facilitates the twist drill to process the first hole 201 on the pipe 20 .

During processing, the second hole processing moving device 1221 can drive the second puncher 1222 to approach or move away from the pipe 20 and can move along the extension direction of the pipe 20.

[0129] Specifically, the second hole processing moving device 1221 includes a second hole processing moving seat 12211 and a second hole processing driving device 12212 disposed thereon.

[0130] The second hole processing driving device 12212 adopts a cylinder structure, and the second punching machine 1222 includes a second milling cutter.

[0131] During processing, the second hole processing driving device 12212 drives the second punching machine 1222 to approach the tube 20 and processes the second holes 202 on the front side wall and the rear side wall of the tube 20 .

[0132] In some specific embodiments, reference Figure 3 The hole processing device 12 includes a third hole processing structure 123 for processing the third hole 203. The third hole processing structure 123 includes a third hole processing moving device 1231 and a plurality of third punching machines 1232 arranged in sequence thereon. Each third punching machine 1232 includes a third punching motor 12321 and a third punching shaft 12322 that are transmission-connected. During processing, the third hole processing moving device 1231 can drive the third punching machine 1232 to approach or move away from the pipe 20 and can move along the extension direction of the pipe 20.

[0133] Specifically, a mounting frame 101 is provided on the processing table 10, and the third hole processing moving device 1231 includes a third hole processing driving device 12311 and a mounting plate 12312 provided thereon.

The third hole processing driving device 12311 adopts the driving form of "motor + screw rod" to provide sufficient power for synchronously driving the mounting plate 12312 and multiple third punching machines 1232. During processing, the third hole processing driving device 12311 drives the third punching machine 1232 to approach the pipe 20 and processes the third hole 203 on the upper side wall of the pipe 20. The third punching shaft 12322 is a third milling cutter.

[0134] Each third punching machine 1232 includes a third punching motor 12321 and a third punching shaft 12322 which are transmission-connected, so that the control device of the pipe processing equipment can accurately monitor the working condition of each third punching shaft 12322 for timely adjustment or maintenance, which is beneficial to improving product quality.

[0135] In some specific embodiments, reference Fig.10 and Fig.11 The notch processing device 22 includes a notch processing drive device 224 and a first notch processing structure 221. The first notch processing structure 221 includes two first cutting dies 2212 and two first cutting knives 2213 which are arranged in a one-to-one correspondence. The first cutting die 2212 is provided with a V-shaped cutting groove 22121. The first cutting knife 2213 is provided with a V-shaped blade 22131 which matches the V-shaped cutting groove 22121. The first cutting knife 2213 is transmission-connected to the notch processing drive device 224 and is located on the upper side of the first cutting die 2212. During processing, the pipe 20 is located on the first cutting die 2212 and the second pipe clamping device 21. The notch processing drive 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 a horizontal direction perpendicular to the pipe 20 to process a V-shaped notch 204 on the pipe 20.

[0136] A V-shaped notch 204 is processed on the tube 20 through the first notch processing structure 221, so that the tube 20 can be bent at the V-shaped notch 204. After bending, the two sides of the V-shaped notch 204 are welded on one side to form an angled strip pipe fitting, enriching the product variety.

[0137] Specifically, the notch processing device 2 also includes a third guide rail group 223 provided on the processing table 10 and extending along the direction of the pipe 20, and the second pipe clamping device 21 includes a plurality of second pipe clamping structures arranged in sequence along the direction of the pipe 20. The second pipe clamping structure includes a second pipe clamping seat and a second pipe clamping cylinder provided thereon, and the second pipe clamping seat is clamped on the third guide rail group 223 and can move along the third guide rail group 223.

[0138] The first cutting die 2212 is disposed between two adjacent second pipe clamping structures, and the first cutting die 2212 is clamped on the third guide rail set 223 and can move along the third guide rail set 223. The first cutting die 2212 is provided with a first cutting accommodating groove 22122 for the pipe 20 to pass through, and the first cutting accommodating groove 22122 is connected to the V-shaped cutting groove 22121 and is perpendicular to each other. With such a configuration, the positions of the second pipe clamping structure and the first cutting die 2212 can be adjusted according to actual needs, so that the two do not interfere with each other and affect the processing, which is conducive to improving the processing quality and efficiency, and is also conducive to expanding the application scope of the pipe processing equipment.

[0139] The notch processing drive device 224 adopts a hydraulic structure, including a first hydraulic cylinder 22111 provided on the mounting frame 101 and a second hydraulic cylinder 22112 provided on the first hydraulic cylinder 22111. The first cutting knife 2213 is provided on the second hydraulic cylinder 22112, the first hydraulic cylinder 22111 is used to drive the second hydraulic cylinder 22112 to move up and down, and the second hydraulic cylinder 22112 is used to drive the first cutting knife 2213 to move forward and backward.

[0140] During processing, the pipe 20 is clamped on a plurality of second pipe clamp cylinders and passes through the first cutting receiving groove 22122 on the first cutting die 2212. 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 lowest 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. Finally, the second hydraulic cylinder 22112 drives the first cutting knife 2213 to move forward and backward to cut V-shaped incisions on the front side wall and the rear side wall of the pipe 20, respectively, and complete the processing of the V-shaped notch 204. The processing method first penetrates the upper side wall of the pipe 20, and then moves forward and backward to cut the front side wall and the rear side wall of the pipe 20, which is conducive to avoiding deformation of the incision of the pipe 20 after the V-shaped notch 204 is processed, thereby ensuring product quality.

[0141] In some specific embodiments, reference Fig.18 The notch processing device 2 also includes a chip removal structure 7, which corresponds to the position of the first cutting mold 2212. After the first cutting knife 2213 processes the tube 20 on the first cutting mold 2212, the chip removal structure 7 pushes out or sweeps out the debris on the tube 20.

[0142] Specifically, the processing table 10 is provided with a chip removal hole, and the chip removal structure 7 includes a chip removal brush and a chip removal drive device. When the pipe 20 is placed on the first cutting die 2212, the chip removal brush is located at the front side of the pipe 20, and the chip removal hole is located at the rear side of the pipe 20.

[0143] When processing the V-shaped notch, after the first cutting knife 2213 is inserted into the pipe 20, it first moves forward to cut the front side wall of the pipe 20. When cutting the front side wall, the front side wall will not be completely cut, and a thickness of about 0.1 mm will be left uncut; then the first cutting knife 2213 moves backward to cut the rear side wall of the pipe 20, and the cut chips on the rear side wall will fall from the rear side of the pipe 20. After the cutting action is completed, the chip removal drive device drives the chip removal brush to move backward to sweep out the cut part of the front side wall and drop it from the rear side of the pipe 20. In this way, the chips generated when cutting the V-shaped notch can fall from the rear side of the pipe 20 and be discharged through the chip removal hole, which is conducive to improving the chip removal effect and avoiding affecting the subsequent processing of the pipe 20.

[0144] In some other embodiments, when the tube 20 is placed on the first cutting die 2212 , the chip brush is located at the rear side of the tube 20 , and the chip removal hole is located at the front side of the tube 20 .

[0145] In some other embodiments, the chip removal structure 7 includes a push rod or other structures that can push the chips to fall.

[0146] In some specific embodiments, reference Fig.11 First limiting steps 22123 are provided on both sides of the V-shaped groove 22121 on the first cutting mold 2212, and second limiting steps 22132 are provided on both sides of the V-shaped blade 22131 of the first cutting knife 2213. The first cutting knife 2213 is limited in its downward movement by the first limiting step 22123 and the second limiting step 22132, so that the first cutting knife 2213 stops moving downward when it is about to contact the pipe 20, thereby ensuring the cutting accuracy and protecting the pipe 20.

[0147] In some specific embodiments, reference Fig.10 and Fig.12The notch processing device 22 includes a notch processing driving device 224 and a second notch processing structure 222. The second notch processing structure 222 includes two second cutting dies 2222 and two second cutting knives 2223 which are arranged in a one-to-one correspondence. The second cutting knives 2223 are transmission-connected to the notch processing driving device 224 and are located on the upper side of the second cutting die 2222. During processing, the tube 20 is located on the second cutting die 2222 and the second tube clamping device 21. The notch processing driving device 224 first drives the second cutting knife 2223 to move downward, and then drives the second cutting knife 2223 to move in a horizontal direction perpendicular to the tube 20, so as to process a second notch 205 at the end of the tube 20.

[0148] Specifically, the second cutting knife 2223 is disposed on the second hydraulic cylinder 22112 of the notch processing driving device 224. The second cutting die 2222 is clamped on the third guide rail set 223 and can move along the third guide rail set 223. During processing, the two second cutting dies 2222 respectively correspond to the two ends of the pipe 20. The second cutting die 2222 is provided with a second cutting receiving groove 22221 for the pipe 20 to pass through.

[0149] Such an arrangement enables the notch processing device 2 to process multiple notches on the pipe 20 at the same time, which is beneficial to improving the processing efficiency.

[0150] In this embodiment, the pipe 20 is a square pipe, and an extension plate 206 is provided on the upper side of the square pipe. During processing, the pipe 20 is clamped on a plurality of second pipe clamp cylinders and passes through the second cutting receiving groove 22221 on the second cutting die 2222. Then, the first hydraulic cylinder 22111 drives the second hydraulic cylinder 22112 and the second cutting knife 2223 to move downward until the lowermost end of the second cutting knife 2223 is about to contact the upper 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 process the second notch 205 at the end of the extension plate 206.

[0151] In some specific embodiments, reference Figure 3 The pipe processing equipment also includes a grinding device 4, which is arranged next to the second pipe clamping device 21. The grinding device 4 includes a grinding movable device 41 and a grinder 42 which are transmission-connected. During grinding, the grinding movable device 41 can drive the grinder 42 to approach or move away from the pipe 20 and can move along the extension direction of the pipe 20.

[0152] Specifically, the grinding device 4 is arranged at the rear side of the second pipe clamping device 21. The grinding moving device 41 includes a grinding seat and a grinding driving device 412 arranged on the grinding seat, and the grinding machine 42 is arranged on the grinding driving device 412. The grinding seat is clamped on the third guide rail group 223 and can move along the third guide rail group 223, and can adjust its position according to the position of the second hole 202 on the rear side wall of the pipe 20. The grinding machine 42 is used to grind the burrs protruding outside the periphery of the second hole 202 on the rear side wall of the pipe 20.

[0153] The grinding device 4 is arranged beside the second pipe clamping device 21, so that the grinding device 4 can grind the pipe 20 while the notch processing device 2 is processing the pipe 20. Since the structural strength of the pipe 20 is reduced after the notch processing, in the prior art, the pipe 20 is generally firstly grinded after the hole processing, and then the notch processing is performed. In this embodiment, the notch processing and grinding are performed at the same time, which will not cause additional damage to the pipe 20, and is also conducive to more reasonably allocating the processing time of each process, which is conducive to further shortening the processing time of the pipe 20 and improving the processing efficiency.

[0154] In some specific embodiments, reference Figure 1 , Figure 2 , Figures 13 to 15 The pipe processing equipment also includes a processing table 10, a loading device 5 and a unloading device 6.

The loading conveying component 51 is located at the lower side of the loading avoidance groove 102 and protrudes from the processing table 10. The loading and lifting component 52 is directly opposite to the loading and lifting groove 102. When loading, the pipe 20 is transported to the bottom of the loading avoidance groove 102 by the loading conveying component 51, and the loading and lifting component 52 pushes the pipe 20 to the loading Above the workbench 10, for clamping of the first pipe clamping device 11; the unloading device 6 includes a unloading and lifting assembly 61 and a unloading conveying assembly 62, the unloading and conveying assembly 62 is located at the lower side of the loading avoidance groove 102 and protrudes from the processing table 10, the unloading and lifting assembly 61 includes a unloading and lifting driving device 611 and an unloading inclined platform 612 arranged thereon, the upper and lower ends of the unloading inclined platform 612 respectively correspond to the positions of the second pipe clamping device 21 and the unloading avoidance groove 103. When unloading, the unloading and lifting driving device 611 drives the unloading inclined platform 612 to move upward, and pushes the pipe 20 up to separate from the second pipe clamping device 21, so that the pipe 20 slides or rolls along the unloading inclined platform 612 to the unloading conveying assembly 62.

[0155] Specifically, the loading conveying assembly 51 includes a loading conveying frame and a loading conveying belt arranged thereon, and the loading and lifting assembly 52 includes a loading and lifting cylinder and a loading clamp cylinder arranged thereon, which is conducive to improving the stability of loading. The unloading conveying assembly 62 includes an unloading conveying frame 621 and an unloading conveying belt 622 arranged thereon, and the unloading and lifting driving device 611 is an unloading and lifting cylinder.

[0156] With such arrangement, the pipe feeding device 5 and the unloading device 6 are integrated with the hole processing equipment 1 and the notch processing equipment 2 to realize automation, which is beneficial to improving production efficiency and product quality.

[0157] After the material loading and lifting component 52 lifts the pipe 20 to the corresponding position of the hole processing device 1, the pipe 20 is still supported and horizontally radially positioned during the hole processing. Therefore, the material loading and lifting component 52 can be regarded as a part of the first pipe clamping device 11, so that the material loading and lifting component 52 has diversified functions, and the pipe 20 can be more fully supported during the hole processing, which is also conducive to making the hole processing device 1 and the material loading device 5 more compact.

[0158] In some specific embodiments, reference Fig.17 The unloading conveying assembly 62 includes an unloading conveying frame 621, an unloading conveying belt 622 and an unloading conveying angle adjustment device 623 arranged thereon. The unloading conveying frame 621 is provided with an unloading conveying driving device.

A locking member is provided between the fixed frame 6231 and the movable frame 6232, and the locking member can fix the movable frame 6232 on the fixed frame 6231. The upper end of the movable frame 6232 is rotatably connected to one end of the material unloading conveying frame 621, and the inclination of the material unloading conveying frame 621 can be adjusted by adjusting the height of the movable frame 6232, so that the material unloading conveying belt 622 forms a slope, providing a buffering effect for the pipe 20 falling from the material unloading ramp 612, and preventing the pipe 20 from being damaged.
