Description

Technical Field

[0001] This invention relates to the field of pipe processing equipment, and in particular to a processing equipment and method for coaxial pipe rib directional debonding, brushing, and punching of pipe ends. Background Technology

[0002] Currently, the processing of coaxial pipes for automotive air conditioning requires rib orientation, followed by brushing, pipe end processing, punching, and other processing steps. However, these processing steps require transfer between multiple processing machines in existing equipment, resulting in low processing efficiency and inaccurate pipe positioning.

[0003] Especially after the internal ribs of the pipe fittings are oriented, each transfer may cause the pipe fittings to rotate circumferentially, which will cause the internal ribs to shift, leading to the shift of all subsequent processes. Summary of the Invention

[0004] The purpose of this invention is to provide a processing equipment and method for coaxial tube reinforcement directional debonding, brushing, and end punching that solves the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, the present invention provides a processing method for integrally punching holes at the end of a coaxial tube with directional debonding and brushing, comprising the following steps:

[0006] Step 1: The loading rack sequentially loads each pipe fitting to be processed into the rib orientation mechanism;

[0007] Step 2: The pipe falls into the V-groove, the positioning plate moves and pushes the pipe end, so that the pipe end moves to the set processing position, and then the clamping roller presses down, cooperating with the driving wheel and the driven wheel to position and clamp the pipe in the circumference. The driving wheel rotates, so that the pipe rotates at a uniform speed.

[0008] Step 3: Move the positioning rod towards the pipe fitting until the end of the positioning rod extends into the inside of the pipe end to be processed. The outer rib on the outside of the positioning rod positions the inner rib on the inside of the pipe end, causing the pipe fitting to stop rotating and completing the rib orientation.

[0009] Step 4: The robotic arm picks up the pipe fitting after the ribs have been oriented, and the clamping rollers rise and disengage. The robotic arm then moves the pipe fitting to the boring mechanism to remove the ribs from the pipe end, thus removing the internal ribs from the end of the pipe fitting.

[0010] Step 5: The robotic arm transfers the debonded pipe fittings to the brushing mechanism, where a rotating wire brush removes the burrs from the pipe ends.

[0011] Step 6: The brushed pipe fittings are sequentially transferred to the extrusion drum mechanism for extrusion processing and the punching mechanism for drilling side holes. After the pipe fittings are processed, the pipe fittings are stacked uniformly by the robot.

[0012] Furthermore, the rib orientation mechanism includes a plurality of V-shaped plates arranged sequentially along the axial direction of the pipe fitting and a movably arranged orientation mounting plate. The upper part of the V-shaped plate is provided with a V-shaped groove. A guide block is connected to the orientation mounting plate. A positioning rod is movably mounted in the guide block. An elastic element is provided between the positioning rod and the guide block. The orientation mounting plate moves along the axial direction of the pipe fitting.

[0013] Furthermore, a positioning cylinder mounting plate is movably provided on one side of the directional mounting plate, a positioning cylinder is connected to the positioning cylinder mounting plate, and a positioning plate is provided at the output end of the positioning cylinder, so that the positioning cylinder mounting plate and the positioning cylinder cooperate to drive the positioning plate to move and push the tube end.

[0014] Furthermore, a roller seat is provided on the side of one of the V-shaped plates, and a driving wheel and a driven wheel are rotatably connected to the roller seat so that the pipe is supported between the driving wheel and the driven wheel. The side of the roller seat has a lifting and lowering clamping rod, one end of which is rotatably connected to a roller pressure frame. The clamping roller is rotatably connected to the roller pressure frame, and the side of the roller pressure frame is rotatably connected to the roller seat so that when the clamping rod rises, the roller pressure frame drives the clamping roller to press down on the pipe.

[0015] Furthermore, the roller seat is mounted on the adjusting frame, and one end of the pressing drive for controlling the pressing rod is rotatably connected to the side of the adjusting frame, and the adjusting frame is mounted on the fixed seat of the lifting mechanism; the end of the positioning rod away from the pipe is connected to a positioning sensor block. When the positioning rod extends into the pipe end for positioning, the positioning sensor block contacts the side of the guide block to indicate that the positioning rod has been inserted into place.

[0016] Furthermore, the boring mechanism includes a boring mounting plate that can be moved along the axial direction of the pipe, a boring drive mounted on the boring mounting plate, and a boring cutter mounted on the output end of the boring drive. A boring auxiliary pneumatic gripper is provided in the moving direction of the boring mounting plate so that when the boring auxiliary pneumatic gripper clamps the outer wall of the pipe, the boring cutter performs boring treatment on the inner rib of the pipe end.

[0017] Furthermore, an anti-chip cover is provided on the outer side of the boring drive and the boring auxiliary gripper. A chip suction cover is provided on the inner side of the anti-chip cover near the machining position of the boring tool on the tube end. An air blowing block is provided on the side of the boring auxiliary gripper away from the boring drive. The air blowing block can move along the axial direction of the tube and is connected to an air pipe on its side so that the air blowing block blows air into the tube and drives the waste chips into the chip suction cover.

[0018] Furthermore, the extrusion mechanism includes a movable die base and a die mounting base that is raised and lowered on the die base. Several dies are sequentially mounted on the die mounting base along the height direction so that the die mounting base can be raised and lowered to adjust different dies. A die clamping mold for clamping pipe fittings is provided in the moving direction of the die base.

[0019] Furthermore, the brushing mechanism includes a brushing die for clamping the pipe fitting, a brushing drive unit disposed on one side of the brushing die, and a wire brush installed at the output end of the brushing drive unit, so that when the pipe fitting is clamped in the brushing die, the brushing drive unit drives the wire brush to rotate and brush the inner wall of the pipe fitting end; the punching mechanism includes a punching die for clamping the pipe fitting, a punching drive unit disposed on one side of the punching die, and a punch installed at the output end of the punching drive unit. The punching die has a mandrel on its side so that when the pipe fitting is clamped in the punching die, the mandrel extends into the inside of the pipe fitting to support the inner wall. A waste sheet box is telescopically provided on one side of the punching die. When the punch completes the punching, the waste sheet falls into the waste sheet box as the punch moves downward.

[0020] The present invention also discloses a processing equipment for coaxial tube reinforcement directional debonding brushing tube end punching, which is processed according to the above processing method.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. After the pipe fittings are oriented, the boring, deburring, pipe end treatment and punching processes are all performed on the same equipment, which effectively shortens the overall processing time and prevents positioning deviations during transportation.

[0023] 2. Before rib orientation, the pipe end position is initially positioned using a positioning plate to ensure that the subsequent rib orientation action of the positioning rod is stable and accurate, avoiding positioning failure due to uneven pipe ends, and even processing errors in all subsequent processes.

[0024] 3. During rib orientation, the outer rib around the positioning rod guides and positions the inner rib at the end of the pipe fitting. The positioning rod remains stationary while the pipe fitting rotates, allowing the inner and outer ribs to mesh and achieve precise positioning. The elastic element ensures that if the outer and inner ribs come into contact and the positioning rod cannot extend into the pipe fitting, the elastic element provides a buffering force, allowing the positioning rod to retract in a controlled manner, avoiding damage caused by hard collisions. After rotating to the meshing position, it automatically resets to complete the positioning, improving the stability of the mechanism's operation and extending its service life.

[0025] 4. The clamping action of the adjusting plate in conjunction with the clamping rollers can adjust the axis of pipe fittings of different sizes and specifications, ensuring that the axis of pipe fittings of different sizes is consistent with the machining center;

[0026] 5. After boring with a boring tool, the waste chips inside the pipe can be cleaned by using an air blowing block in conjunction with a chip suction hood. The air blowing and chip suction are carried out simultaneously to effectively avoid chip residue.

[0027] 6. The adjustable die mounting base allows for quick adjustment of different dies to suit pipe end processing requirements. Attached Figure Description

[0048] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0049] like Figures 1-17 The present invention provides a processing device and method for coaxial tube rib directional debonding, brushing, and punching of tube ends, comprising the following steps:

[0050] Step 1: The loading rack 1 sequentially loads each pipe fitting 8 to be processed into the rib orientation mechanism 2;

[0051] Step 2: The pipe fitting 8 falls into the V-groove 21. The positioning plate 22 moves and pushes the pipe end, so that the pipe end moves to the set processing position. Then the clamping roller 23 presses down, and the driving wheel 24 and the driven wheel 25 work together to position and clamp the pipe fitting 8 in the circumference. The driving wheel 24 rotates, so that the pipe fitting 8 rotates at a uniform speed.

[0052] Step 3: The positioning rod 26 moves towards the pipe fitting 8 until the end of the positioning rod 26 extends into the inside of the pipe end to be processed. The outer rib 27 on the outside of the positioning rod 26 positions the inner rib 81 on the inside of the pipe end, so that the pipe fitting 8 stops rotating and the rib orientation is completed.

[0053] Step 4: The robotic arm 7 grabs the pipe fitting 8 after the ribs are oriented, and the clamping roller 23 rises and disengages. The robotic arm 7 then moves the pipe fitting 8 to the boring mechanism 3 to remove the ribs at the pipe end, so that the inner ribs 81 at the end of the pipe fitting 8 are removed.

[0054] Step 5: The robotic arm 7 transfers the debonded pipe fitting 8 to the brushing mechanism 4, where the rotating wire brush 41 removes the burrs from the pipe end.

[0055] Step 6: The brushed pipe fittings 8 are sequentially transferred to the extrusion drum mechanism 5 by the robotic arm 7 for extrusion drum processing and the side holes 82 are drilled at the punching mechanism 6. After the pipe fittings 8 are processed, the robotic arm 7 stacks the pipe fittings 8 uniformly.

[0056] The feeding rack 1 has a storage tank that supports several pipe fittings 8. The bottom of the storage tank is inclined, so that the pipe fittings 8 automatically slide to the top plate at the discharge end under the action of gravity. The top plate is controlled to rise by a cylinder or motor and pushes the pipe fittings 8 on it to rise until the pipe fittings 8 rise to the discharge position. At the same time, the end of the top plate is also inclined, so that the pipe fittings 8 at the discharge position will roll down into the V-shaped groove 21 with the inclined surface, realizing continuous automatic feeding.

[0057] The robotic arm 7 includes a horizontally arranged linear guide rail. The slider moves horizontally along the linear guide rail via a motor and a lead screw. A vertical guide rail is connected to the slider. The gripper moves vertically along the vertical guide rail via a servo motor and a lead screw. The gripper also has a rotary cylinder to control the circumferential rotation of the gripper.

[0058] Preferably, the rib orientation mechanism 2 includes a plurality of V-shaped plates 28 arranged sequentially along the axial direction of the pipe fitting 8 and a movably disposed orientation mounting plate 29. The upper part of the V-shaped plate 28 is provided with a V-shaped groove 21. A guide block 210 is connected to the orientation mounting plate 29. A positioning rod 26 is movably disposed in the guide block 210, and an elastic element 211 is provided between the positioning rod 26 and the guide block 210. The orientation mounting plate 29 moves along the axial direction of the pipe fitting 8.

[0059] Specifically, after the pipe fitting 8 is pushed and fed to several V-shaped plates 28 by the feeding rack 1, the pipe fitting 8 is supported by the V-shaped groove 21. Under the action of gravity, the pipe fitting 8 is automatically positioned in the V-shaped groove 21. When the positioning rod 26 needs to orient the pipe end, the orientation mounting plate 29 drives the guide block 210 and the positioning rod 26 to move axially along the pipe fitting 8, so that the end of the positioning rod 26 extends into the inside of the pipe end, and the outer rib 27 and the inner rib 81 contact and cooperate to achieve circumferential positioning; if the outer rib 27 and the inner rib 81 are completely aligned... When the positioning rod 26 cannot be inserted into the pipe end due to inaccuracy, the elastic element 211 is compressed, allowing the positioning rod 26 to retract briefly to avoid interference. Then, under the fine adjustment of the rotation of the pipe fitting 8, it automatically finds the alignment gap until the outer rib 27 and the inner rib 81 complete the positioning engagement, ensuring that the positioning rod 26 is stably inserted into the inner side of the pipe end. The positioning rod 26 is stationary, so that the pipe fitting 8 during the rotation process is positioned by the outer rib 27 of the positioning rod 26, thereby achieving precise alignment of the inner rib 81 and the outer rib 27, as well as circumferential positioning of the pipe fitting 8.

[0060] The directional mounting plate 29 is controlled to move by a cylinder in conjunction with a guide rail, and the elastic element 211 adopts a spring structure.

[0061] Preferably, a positioning cylinder mounting plate 212 is movably provided on one side of the directional mounting plate 29, and a positioning cylinder 213 is connected to the positioning cylinder mounting plate 212. A positioning plate 22 is provided at the output end of the positioning cylinder 213, so that the positioning cylinder mounting plate 212 and the positioning cylinder 213 cooperate to drive the positioning plate 22 to move and push the tube end.

[0062] Specifically, during the initial positioning of the pipe end, the positioning cylinder mounting plate 212 drives the positioning cylinder 213 to move towards the pipe fitting 8. At the same time, the positioning cylinder 213 pushes the positioning plate 22 to extend to the pipe end position, so that the positioning plate 22 axially pushes and positions the pipe end, ensuring that the pipe fitting 8 is accurately positioned in the axial direction. Subsequently, the positioning cylinder mounting plate 212 and the positioning cylinder 213 retract synchronously to provide space for the subsequent rib orientation operation.

[0063] The movement of the positioning cylinder mounting plate 212 is controlled by the cylinder and the guide rail, and the positioning cylinder mounting plate 212 moves axially along the pipe fitting 8, while the positioning plate 22 moves radially along the pipe fitting 8.

[0064] In one embodiment of this solution, material level sensors are provided at both the V-groove 21 and the positioning plate 22 to detect whether the pipe fitting 8 is in place, and proceed to the next step after the pipe fitting is detected to be in place.

[0065] Preferably, a roller seat 214 is provided on the side of one of the V-shaped plates 28, and a driving wheel 24 and a driven wheel 25 are rotatably connected to the roller seat 214 so that the pipe 8 is supported between the driving wheel 24 and the driven wheel 25. The side of the roller seat 214 has a lifting and lowering clamping rod 215. One end of the clamping rod 215 is rotatably connected to a roller pressure frame 216, and a clamping roller 23 is rotatably connected to the roller pressure frame 216. The side of the roller pressure frame 216 is rotatably connected to the roller seat 214 so that when the clamping rod 215 rises, the roller pressure frame 216 drives the clamping roller 23 to press down on the pipe 8.

[0066] Specifically, the roller seat 214 provides rolling support for the driving wheel 24 and the driven wheel 25, allowing the pipe fitting 8 to be stably positioned between the driving wheel 24 and the driven wheel 25. The initial pressing rod 215 descends, causing the pressing roller 23 to disengage from the pipe fitting 8's placement position, thus facilitating the loading space for the pipe fitting 8. Subsequently, after the positioning plate 22 performs initial positioning of the pipe fitting 8, the pressing rod 215 rises, driving the roller pressing frame 216 to press down via the rotating connection of the roller seat 214 as a lever fulcrum. This causes the pressing roller 23 to move down to the outer circumference of the pipe fitting 8, achieving radial pressing of the pipe fitting 8 and preventing it from jumping or shifting during rotational positioning, ensuring circumferential positioning accuracy. Subsequently, the driving wheel 24 rotates, driving the pipe fitting 8 to rotate, cooperating with the positioning rod 26 for rib orientation.

[0067] Both the driving wheel 24 and the driven wheel 25 are connected to the roller seat 214 through bearings. The driving wheel 24 is driven by a motor, and the driven wheel 25 is driven to rotate by gears or synchronous belts, thereby ensuring the stability and synchronicity of the pipe 8 during rotation.

[0068] Preferably, the roller seat 214 is mounted on the adjusting frame 217, and one end of the pressing drive member 218 used to control the pressing top rod 215 is rotatably connected to the side of the adjusting frame 217, and the adjusting frame 217 is mounted on the fixed seat 219 with lifting and lowering. The end of the positioning rod 26 away from the pipe 8 is connected to a positioning sensor block 220. When the positioning rod 26 extends into the pipe end for positioning, the positioning sensor block 220 contacts the side of the guide block 210 to indicate that the positioning rod 26 has extended into place.

[0069] Specifically, the clamping drive component 218 is a cylinder structure, which controls the lifting and lowering of the clamping top rod 215 to achieve rapid clamping and release of the clamping roller 23 on the pipe fitting 8. Due to the rotating connection at one end of the clamping drive component 218, the clamping top rod 215 is subjected to more uniform force during the lifting and lowering process. Under the clamping action, the clamping drive component 218 can generate a certain amount of swing to ensure the fit between the clamping roller 23 and the outer circumference of the pipe fitting 8. At the same time, the lifting design of the adjusting frame 217 on the fixed base 219 makes it easy to adapt to workpieces with different pipe diameters and improves the versatility of the equipment. The positioning sensor block 220 moves synchronously with the positioning rod 26 and cooperates with external sensors (such as inductive switches, position sensors, etc.) to provide real-time feedback on the stroke position of the positioning rod 26 to ensure accurate and reliable circumferential positioning of the pipe fitting 8. When the positioning sensor block 220 triggers the external sensor, the system determines that the positioning rod 26 has completed its insertion position, and the drive wheel 24 rotates for a period of time before stopping.

[0070] When the pipe fitting 8 is oriented and the drive wheel 24 is rotating, there is sliding friction between the drive wheel 24 and the pipe fitting 8. Sufficient time is reserved for the drive wheel 24 to rotate in order to avoid problems such as the outer rib 27 abutting against the inner rib 81.

[0071] Preferably, the boring mechanism 3 includes a boring mounting plate 31 that can be moved along the axial direction of the pipe 8, a boring drive 32 mounted on the boring mounting plate 31, and a boring cutter 33 mounted on the output end of the boring drive 32. A boring auxiliary pneumatic gripper 34 is provided in the moving direction of the boring mounting plate 31 so that when the boring auxiliary pneumatic gripper 34 clamps the outer wall of the pipe 8, the boring cutter 33 performs boring treatment on the inner rib 81 of the pipe end of the pipe 8.

[0072] Specifically, after the robotic arm 7 moves the pipe 8 to the boring auxiliary gripper 34 for clamping and fixing, the boring mounting plate 31 drives the boring drive 32 to move towards the pipe end, and controls the boring cutter 33 to rotate to perform boring processing on the inner rib 81 on the inner side of the pipe end through the boring drive 32.

[0073] The boring mounting plate 31 is driven by a cylinder or servo motor to reciprocate along the guide rail, ensuring the precise feeding of the boring tool 33; the boring drive component 32 is a servo motor, which achieves constant speed rotation of the boring tool 33 through high-precision control, ensuring a stable and reliable cutting process; the boring auxiliary gripper 34 is controlled by cylinders on both sides to clamp and open.

[0074] Preferably, a chip-proof cover 35 is provided on the outer side between the boring drive 32 and the boring auxiliary gripper 34. A chip suction cover 36 is provided on the inner side of the chip-proof cover 35 near the machining position of the boring tool 33 at the tube end. An air blowing block 37 is provided on the side of the boring auxiliary gripper 34 away from the boring drive 32. The air blowing block 37 can move along the axial direction of the tube 8, and an air pipe is connected to the side of the air blowing block 37 so that the air blowing block 37 blows air into the tube 8, driving the waste chips into the chip suction cover 36.

[0075] Specifically, the boring area is sealed by the anti-chip shield 35 to effectively prevent cutting chips from splashing. The chip suction hood 36 is connected to a negative pressure device to remove the metal chips generated during machining in real time, avoiding chip accumulation from affecting the boring accuracy and tool life. At the same time, after the tube end is machined, the air blowing block 37 moves closer to the other end of the tube 8 and is supplied with airflow by the air pipe, so that the air blowing block 37 blows air onto the tube end, blowing the waste chips inside into the chip suction hood 36, which is then sucked in with the negative pressure device.

[0076] One side of the air blowing block 37 is connected to the cylinder and is initially in a retracted state to provide space for the pipe 8 to enter the boring mechanism 3. After boring is completed, the cylinder pushes the air blowing block 37 to the other end of the pipe 8 to ensure stable air blowing.

[0077] Preferably, the extrusion mechanism 5 includes a movable die base 51 and a die mounting base 52 that is raised and lowered on the die base 51. A plurality of dies 53 are sequentially mounted on the die mounting base 52 along the height direction so that the die mounting base 52 can be raised and lowered to adjust different dies 53. A die clamping mold 54 for clamping the pipe fitting 8 is provided in the moving direction of the die base 51.

[0078] Specifically, the die holder 51 moves precisely along the guide rail to the predetermined position of the pipe 8 under servo drive. The die 53 mounting plate is vertically lifted by a hydraulic cylinder, which drives the switching of different specifications of dies 53. Then, after the die clamping mold 54 clamps the pipe 8, the die holder 51 drives the current die 53 to extrude the pipe end.

[0079] The die 53 mounting plate is controlled by a servo motor and a lead screw to move along the track, and the die base 51 is controlled by a hydraulic cylinder to move along the track for processing; the die clamping mold 54 is controlled by cylinders on both sides to clamp and open.

[0080] Preferably, the brushing mechanism 4 includes a brushing mold 42 for clamping the pipe fitting 8, a brushing drive 43 disposed on one side of the brushing mold 42, and a wire brush 41 installed at the output end of the brushing drive 43, so that when the pipe fitting 8 is clamped in the brushing mold 42, the brushing drive 43 drives the wire brush 41 to rotate and brush the inner wall of the end of the pipe fitting 8; the punching mechanism 6 includes a punching mold 61 for clamping the pipe fitting 8, a punching drive 62 disposed on one side of the punching mold 61, and a punch 63 installed at the output end of the punching drive 62. The punching mold 61 has a mandrel 64 on its side, so that when the pipe fitting 8 is clamped in the punching mold 61, the mandrel 64 extends into the inside of the pipe fitting 8 to support the inner wall. A waste sheet box 65 is telescopically disposed on one side of the punching mold 61. When the punch 63 completes punching, the waste sheet falls into the waste sheet box 65 as the punch moves downward.

[0081] Specifically, after the robotic arm 7 places the pipe end on the outer periphery of the wire brush 41, the brush bristle clamp 42 closes and fixes the pipe 8, and the brush bristle drive 43 starts and drives the wire brush 41 to rotate at high speed, so as to uniformly brush the inner wall of the pipe end 8 and effectively remove welding residual burrs.

[0082] When the robotic arm 7 moves the pipe 8 to the punching mechanism 6, it first moves horizontally a certain distance so that the pipe end is fitted into the position of the mandrel 64. Then the punching die 61 closes and fixes the pipe 8. The punching drive 62 pushes the punch 63 to feed radially and completes precise hole opening in the pipe wall. At the same time, the mandrel 64 provides internal support to prevent the pipe 8 from deforming. Meanwhile, the waste sheet box 65 extends into the bottom of the punching to receive the metal waste generated during the punching process.

[0083] The brush clamping die 42 and the punching die 61 are both controlled by cylinders on both sides to clamp and open; the brush drive 43 is a motor; the punching drive 62 is controlled by a hydraulic cylinder to move along the guide rail; the mandrel 64 has a through hole that matches the punch 63 to ensure the stable setting of the punch 63; the waste sheet box 65 is controlled by a cylinder to extend and retract, thereby controlling the extension and retraction of the waste sheet box 65 to be synchronized with the punching operation.

[0084] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
