[0033] In the notching device, the pipe 20 is transported to the die 22 by the feeding device 1, and then is removed from the die 22 after being machined on the die 22. The feeding device 1 and the discharging device 3 are beneficial to improve the rhythm and efficiency of feeding and discharging the pipe 20, and are also beneficial to reduce the possibility of knocking the pipe 20 and the waste rate.

[0034] In some specific embodiments, reference is made to Figure 2 andFigure 5 The notch processing device 2 comprises a first notch processing structure 25, which comprises a first die 221 and a first cutter 231 arranged correspondingly, the first die 221 is provided with a first placing groove 2212 and a V-shaped cutting groove 2211 which are perpendicular to each other and communicate, the first placing groove 2212 is used for placing the pipe 20, the first cutter 231 is provided with a V-shaped blade 2311 which is arranged correspondingly with the V-shaped cutting groove 2211, and the first cutter 231 is drivingly connected to the processing driving device 21.

[0035] Specifically, the first notch processing structure 25 comprises two first dies 221 and two first cutters 231 which are arranged correspondingly, and through the first notch processing structure 25, a V-shaped notch 201 is processed on the pipe 20, so that the pipe 20 can be bent at the V-shaped notch 201, and after bending, the two edges of the V-shaped notch 201 are welded together to form an angular strip-shaped pipe fitting, which enriches the product variety.

[0036] In the embodiment, the notch processing equipment further comprises a processing table 10, and the notch processing device 2 is arranged on the processing table 10. The notch processing device 2 further comprises a guide rail 24, and the die 22 is slidably connected to the guide rail 24, so that the die 22 can be adjusted in position according to the length of the pipe 20 and the different notch processing positions, and the notch processing device 2 can process pipes 20 of different lengths, which is beneficial to expand the application range and improve the production efficiency and benefits.

[0037] The processing table 10 is further provided with a mounting frame, the processing driving device 21 adopts a hydraulic structure form, and comprises a first hydraulic cylinder 211 arranged on the mounting frame and a second hydraulic cylinder 212 arranged on the first hydraulic cylinder 211. The first cutter 231 is arranged on the second hydraulic cylinder 212, the first hydraulic cylinder 211 is used to drive the second hydraulic cylinder 212 to move up and down, and the second hydraulic cylinder 212 is used to drive the first cutter 231 to move forward and backward.

[0038] During processing, the pipe 20 is placed in the first placing groove 2212 of the die 22, then the first hydraulic cylinder 211 drives the second hydraulic cylinder 212 and the first cutter 231 to move downward, so that the first cutter 231 penetrates through the upper side wall of the pipe 20, and stops when the lowermost end of the V-shaped blade 2311 of the first cutter 231 is about to contact the lower side wall of the pipe 20, and finally the second hydraulic cylinder 212 drives the first cutter 231 to move forward and backward to cut V-shaped notches on the front side wall and the rear side wall of the pipe 20 respectively, thereby completing the processing of the V-shaped notch 201. The processing method first penetrates the upper side wall of the pipe 20, and then moves the first cutter 231 forward and backward to cut the front side wall and the rear side wall of the pipe 20, which is beneficial to the deformation of the cutout of the pipe 20 after the V-shaped notch 201 is processed, and ensures the product quality.

[0039] In some specific embodiments, reference is made to Figure 2 andFigure 5 The first mold 221 is provided with a first limiting part 223, and the first cutter 231 is provided with a second limiting part 224 matched with the first limiting part 223, and the first limiting part 223 and the second limiting part 224 are used to limit the downward movement of the first cutter 231 during machining.

[0040] Specifically, the first limiting step 2231 is arranged on both sides of the V-shaped cutting groove 2211 of the first mold 221, and the second limiting step 2241 is arranged on both sides of the V-shaped blade 2311 of the first cutter 231, and the first cutter 231 is limited to move downward by the first limiting step 2231 and the second limiting step 2241, so that the first cutter 231 stops moving downward when it is about to contact the pipe 20, that is, the cutting accuracy is ensured, and the pipe 20 is also protected.

[0041] In some specific embodiments, referring to Figure 2 and Figure 6 The notch machining device 2 comprises a second notch machining structure 26, the second notch machining structure 26 comprises a machining driving device 21 and a second mold 222 and a second cutter 232 arranged correspondingly, the second mold 222 is provided with a second placing groove 2222 and a second cutting groove 2221 perpendicular to each other and communicating, the second placing groove 2222 is used to place the pipe 20, the second cutter 232 is provided with a second cutter blade 2321 matched with the second cutting groove 2221, and the second cutter 232 is drivingly connected to the machining driving device 21.

[0042] Specifically, the second cutter 232 is arranged on the second hydraulic cylinder 212 of the machining driving device 21. The second cutter 232 is clamped on the guide rail 24 and can move along the guide rail 24. During machining, the two second cutters 232 correspond to the two end portions of the pipe 20 respectively.

[0043] In this way, the notch machining device can simultaneously machine multiple notches on the pipe 20, which is beneficial to improve the machining efficiency.

[0044] In this embodiment, the pipe 20 comprises a square tube and an extension plate arranged on the upper side of the square tube. During machining, the pipe 20 is placed in the second placing groove 2222 of the second mold 222, then the first hydraulic cylinder 211 drives the second hydraulic cylinder 212 and the second cutter 232 to move downward, and stops when the lowermost end of the second cutter 232 is about to contact the upper side wall of the pipe 20, and finally the second hydraulic cylinder 212 drives the first cutter 231 to move back and forth to machine the second notch 202 at the end of the extension plate.

[0045] During machining, the pipe 20 is placed in the first placing groove 2212 of the first mold 221 and the second placing groove 2222 of the second mold 222 at the same time, so as to machine the V-shaped notch 201 and the second notch 202 at the same time.

[0046] The second mold 222 is also provided with a first limiting part 223, and the second cutter 232 is also provided with a second limiting part 224.

[0047] In some other embodiments, different molds 22 and cutters 23 with different blade shapes can be used to process different shapes of notches on the pipe 20.

[0048] In some specific embodiments, referring to Figure 9 The processing table 10 further comprises a chip removal structure 5 corresponding to the position of the mold 22. After the cutter 23 processes the pipe 20 on the mold 22, the chip removal structure 5 pushes or sweeps the chips on the pipe 20 out.

[0049] Specifically, the processing table 10 is provided with a chip removal hole, and the chip removal structure 5 comprises a chip removal brush and a chip removal driving device. When the pipe 20 is placed on the mold 22, 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.

[0050] When processing a V-shaped notch, after the first cutter 231 extends into the pipe 20, it first moves forward to cut the front side wall of the pipe 20. When cutting the front side wall, it will not cut the front side wall completely, but will leave a thickness of about 0.1 mm uncut. Then the first cutter 231 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 driving device drives the chip removal brush to move backward to sweep the cut part on the front side wall out and fall from the rear side of the pipe 20. In this way, the chips generated when cutting the V-shaped notch can all fall from the rear side of the pipe 20 and be discharged through the chip removal hole, which is beneficial to improve the chip removal effect and avoid affecting the processing of subsequent pipes 20.

[0051] In some other embodiments, when the pipe 20 is placed on the mold 22, the chip removal brush is located at the rear side of the pipe 20, and the chip removal hole is located at the front side of the pipe 20.

[0052] In some other embodiments, the chip removal structure 5 comprises a push rod or other structure that can push the chips to fall.

[0053] In some specific embodiments, referring to Figure 2 The processing table 10 further comprises a plurality of clamping seats 27 arranged in sequence, and the mold 22 is arranged between two adjacent clamping seats 27. During processing, the clamping seat 27 and the mold 22 jointly support and horizontally and radially limit the pipe 20.

[0054] Specifically, the clamping seat 27 is clamped on the guide rail 24 and can move along the guide rail 24.

[0055] In the existing notching device, during machining, generally only the die 22 supports and horizontally limits the pipe 20. The placing groove on the die 22 for placing the pipe 20 generally cannot be adjusted in width, and the pipe 20 is placed in the placing groove, and the placing groove is slightly wider than the width of the pipe 20. For the pipe 20 with a relatively short length and a relatively large diameter, the supporting effect is sufficient to prevent the pipe 20 from deforming during machining, but for the pipe 20 with a relatively long length and a relatively small diameter, the pipe 20 may deform during notching only by being supported by the die 22. The notching device in the embodiment further comprises a plurality of clamping seats 27, which can support the pipe 20 more accurately, and together with the die 22, support and horizontally limit the pipe 20, which is conducive to reducing the probability of deformation of the pipe 20 during machining and improving the quality of finished products.

[0056] In some specific embodiments, with reference to Figure 1 and Figure 6 , the axial positioning assembly 4 comprises an axial positioning driving device 41 and two oppositely arranged axial positioning members 42, and a supporting structure 43 for supporting the pipe 20 is arranged between the two axial positioning members 42. At least one axial positioning member 42 is in transmission connection with the axial positioning driving device 41, and when the pipe 20 is axially positioned, the pipe 20 is placed on the supporting structure 43, the axial positioning driving device 41 drives the axial positioning members 42 to move, so that the two axial positioning members 42 abut against the two ends of the pipe 20 respectively to limit the axial movement of the pipe 20.

[0057] The pipe 20 positioned by the axial positioning assembly 4 is conducive to improving the accuracy of notching and thus improving the quality of finished products.

[0058] In some specific embodiments, with reference to Figure 1 and Figure 6 , the axial positioning assembly 4 and the notching device 2 are arranged along a direction perpendicular to the arrangement direction of the two axial positioning members 42, and a feeding device 1 is arranged between the axial positioning assembly 4 and the notching device 2. The feeding device 1 is used to transport the pipe 20 from the supporting structure 43 to the die 22.

[0059] Specifically, the pipe 20 is first axially positioned on the axial positioning assembly 4, and then moved to the die 22 of the notching device 2 by the feeding device 1. The feeding device 1 comprises a feeding driving device 11 and a feeding clamping seat 27, and the feeding driving device 11 can drive the feeding clamping seat 27 to move up and down and move along the arrangement direction of the axial positioning assembly 4 and the notching device 2.

[0060] Generally, since the strength of the pipe 20 will be reduced after the notching process, the notching process is arranged after other processing processes. As arranged above, the pipe 20 can be positioned on the supporting structure 43, and then other processing processes are performed, and then the pipe 20 is transported to the die 22 by the feeding device 1, and the pipe 20 can be notched without axial positioning, which is beneficial to improve the processing efficiency of the pipe 20.

[0061] Further, the supporting structure 43 includes a clamping cylinder, which can be used to position the pipe 20 radially, which is beneficial to further improve the feeding accuracy and make the feeding process more smooth.

[0062] In some other embodiments, the axial positioning assembly 4 is integrated with the notching device 2, and the supporting structure 43 includes the die 22 and / or the clamping seat 27. The die 22 and the clamping seat 27 are arranged between the two axial positioning members 42.

[0063] In some specific embodiments, referring to Figure 2 and Figure 3 , the demolding structure 32 includes a discharging ramp 321, and the discharging driving device 31 includes a discharging driving cylinder 311 arranged on the die 22. The discharging ramp 321 and the discharging driving cylinder 311 are in transmission connection. The upper end of the discharging ramp 321 corresponds to the position of the die 22. During discharging, the discharging driving device drives the discharging ramp 321 to move upward, and the pipe 20 on the die 22 is lifted to be separated from the die 22, so that the pipe 20 slides or rolls off along the discharging ramp 321.

[0064] The discharging of the pipe 20 is performed by the discharging ramp 321, which is beneficial to reduce the cost, save space, and make the notching equipment compact compared with other discharging structures.

[0065] In some other embodiments, the demolding structure 32 includes a discharging clamping structure, which is used to clamp and move the pipe 20 away from the die 22.

[0066] In some specific embodiments, referring to Figure 2 and Figure 8 , the discharging device 3 further includes a discharging conveying assembly 33. The discharging conveying assembly 33 includes a discharging conveying frame 331, a discharging conveying belt 332 arranged on the discharging conveying frame 331, and a discharging conveying angle adjusting device 333 arranged on the discharging conveying frame 331. The discharging driving device 31 further includes a discharging conveying driving device 3311 arranged on the discharging conveying frame 331. The discharging conveying driving device 3311 and the discharging conveying angle adjusting device 333 are in transmission connection with the discharging conveying belt 332. The discharging conveying driving device 3311 is used to drive the discharging conveying belt 332 to rotate, and the discharging conveying angle adjusting device 333 is used to adjust the inclination degree of the discharging conveying belt 332. The discharging conveying belt 332 corresponds to the lower end of the discharging ramp 321, so that the pipe 20 can fall from the discharging ramp 321 to the discharging conveying belt 332.

[0067] Specifically, the blank conveying angle adjusting device 333 comprises an adjusting frame, the adjusting frame comprises a fixed frame 3331 and a movable frame 3332, the movable frame 3332 is movably connected to the fixed frame 3331 and can move up and down. A locking piece is arranged between the fixed frame 3331 and the movable frame 3332, and the locking piece can fix the movable frame 3332 on the fixed frame 3331. The upper end of the movable frame 3332 is rotatably connected to one end of the blank conveying frame 331, and the inclination degree of the blank conveying frame 331 can be adjusted by adjusting the height of the movable frame 3332, so that the conveying belt forms a slope, and the pipe 20 falling from the blank slope 321 is provided with a buffering effect, so as to avoid damage to the pipe 20.

[0068] The processing table 10 is provided with a blank avoiding groove corresponding to the lower end position of the blank slope, and the blank conveying belt 332 is located below the blank avoiding groove. After the pipe 20 falls from the blank slope, it passes through the blank avoiding groove and reaches the blank conveying belt 332.

[0069] In some other embodiments, the height of the movable frame 3332 can be adjusted by using a driving device such as a pneumatic cylinder.

[0070] The above is only the preferred embodiment of the present application, and does not limit the patent range of the present application.
