Description

Technical Field

[0001] This application relates to the field of metal processing technology, and in particular to a stamping device for forming metal flanges and a method of using the same. Background Technology

[0002] Metal flanging refers to a forming method in which a mold is used to create a straight wall or flange at a certain angle along a closed or open curved edge on a flat or curved part of a metal blank.

[0003] In related technologies, when flanging metal pipe workpieces, it is usually necessary to fix the pipe workpiece to be processed onto a rotatable clamping platform and control the clamping platform to rotate; then, the stamping equipment on one side of the clamping platform is used to press the position of the pipe workpiece to be processed and deform it to form a flange, thereby realizing the flanging process of the pipe workpiece.

[0004] Regarding the aforementioned technologies, the inventors have discovered that: common pipe workpieces come in a wide variety of styles, and their inner diameters range widely; when it is necessary to perform flanging processing on pipe workpieces with different inner diameters, it is usually necessary to change to a clamping table of different diameters to clamp and fix the pipe workpieces, which makes the overall processing process quite cumbersome and thus needs to be improved. Summary of the Invention

[0005] To improve the convenience of flanging processing of pipe workpieces, this application provides a stamping device for forming metal flanging.

[0006] In a first aspect, the stamping equipment for forming metal flanges provided in this application adopts the following technical solution:

[0007] A stamping device for forming a metal flange includes a support platform for carrying a pipe fitting. A clamping wheel assembly for clamping the end of the pipe fitting is provided on one side of the support platform. A rotating component for driving the pipe fitting to rotate is provided on the clamping wheel assembly. A rotating assembly for driving the clamping wheel assembly to rotate the end of the pipe fitting relative to the support platform is provided on the support platform.

[0008] By adopting the above technical solution, the pipe fitting is placed on the support platform, with a portion of the pipe fitting extending beyond the support platform. Then, the pipe wall of the part to be processed is placed on the clamping wheel assembly. The clamping wheel assembly clamps the pipe wall at the location to be flanged. The rotating component drives the pipe fitting to rotate, and the rotating assembly drives the clamping wheel assembly to rotate the pipe wall at the clamped location. The pipe fitting abuts against the support platform, causing the clamped pipe wall to gradually fold relative to the pipe fitting, thereby achieving a fast and convenient flanged processing of the pipe fitting. This simplifies the clamping steps in the traditional flanged processing of pipe fittings and facilitates flanged processing of pipe fittings with various inner diameters, improving the economic applicability of pipe flanged processing.

[0009] Preferably, the clamping wheel assembly includes a mounting frame, a docking wheel, a sliding block, a pressure wheel, and a driving component; the mounting frame is disposed on one side of the support platform, the docking wheel is rotatably disposed on the mounting frame, and the rotating component is disposed on the mounting frame to drive the docking wheel to rotate; the peripheral wall of the docking wheel has a transition annular groove for the pipe fitting to abut; the sliding block is slidably disposed on the mounting frame, the pressure wheel is rotatably disposed on the sliding block, and the end of the pipe fitting exposed on the support platform is located between the docking wheel and the pressure wheel; the driving component is disposed on the mounting frame to drive the sliding block to move closer to or away from the pressure wheel.

[0010] By adopting the above technical solution, the filter ring groove supports the pipe wall of the fitting, facilitating the positioning of the fitting. When the output end of the control drive extends, it drives the pressure roller to gradually approach the docking roller, so that the pressure roller and the docking roller clamp the pipe wall of the fitting. At this time, when the rotating component drives the docking roller to rotate, the pressure roller can drive the fitting to rotate. When the output end of the control drive retracts, the pressure roller gradually moves away from the docking roller to release the clamping of the fitting, thus facilitating the movement of the fitting. By using the drive to clamp the pipe wall of the fitting with the pressure roller and the docking roller, the fitting to be processed can be quickly positioned, which facilitates the flanging of fittings with various inner diameters, thereby improving the convenience of fitting processing.

[0011] Preferably, the rotating assembly includes a rotating rod and a rotating motor; the rotating rod is rotatably mounted on the side wall of the support platform near the mounting frame, the rotating rod is connected to the mounting frame, and the rotating motor is mounted on the support platform to drive the rotating rod to rotate.

[0012] By adopting the above technical solution, the output end of the control motor drives the rotating rod to rotate, and the rotating rod drives the mounting frame, docking wheel and pressing wheel to rotate. At this time, the pipe wall held by the docking wheel and pressing wheel is bent relative to the pipe fitting, and the rotating component drives the pipe fitting to rotate, so as to continuously adjust the pipe fitting position between the docking wheel and the pressing wheel, thereby realizing the rapid flanging process of the pipe fitting.

[0013] Preferably, a positioning shaft is provided on the support platform, and a limiting wheel is rotatably provided on the positioning shaft to abut against the outer peripheral wall of the pipe fitting. An active gap is left between the limiting wheel and the support platform to facilitate the rotation of the pipe fitting.

[0014] By adopting the above technical solution, when the pipe is rotated, the outer peripheral wall of the pipe abuts against the limiting wheel, and the bent flange of the pipe is located inside the movable gap, so as to limit the position of the pipe and reduce the occurrence of the pipe detaching from the pressing wheel and the connecting wheel when the pipe is flanged.

[0015] Preferably, the support platform has a through-hole for the positioning shaft to slide through, and a movable block is slidably arranged on the bottom wall of the support platform along the length direction of the sliding hole. The movable block is connected to the positioning shaft. A rotating screw is rotatably arranged on the bottom of the support platform along the length direction of the sliding hole. The rotating screw passes through the movable block and is threadedly connected to the movable block. A moving motor is provided at the bottom of the support platform to drive the rotating screw to rotate.

[0016] By adopting the above technical solution, the output end of the moving motor drives the rotating screw to rotate, and the rotating screw drives the moving block to move the positioning shaft, so as to quickly adjust the position of the limit wheel on the bearing platform, thereby facilitating the limit wheel to limit pipes of different diameters and improving the practicality of the limit wheel.

[0017] Preferably, the movable block has a movable groove for the positioning shaft to move, and a guide rod that passes through the positioning shaft is provided inside the movable groove. The length direction of the guide rod is parallel to the length direction of the sliding opening. An elastic element is sleeved on the guide rod. One end of the elastic element is connected to the positioning shaft, and the other end of the elastic element is connected to the inner sidewall of the movable groove.

[0018] By adopting the above technical solution, when the moving block drives the positioning shaft and the limiting wheel to quickly approach the pipe to be processed, the limiting wheel abuts against the outer peripheral wall of the pipe, thereby applying a force to the positioning shaft in the direction away from the pipe. This causes the elastic element to deform and contract under pressure, thus reducing the hard collision between the limiting wheel and the pipe and reducing the occurrence of pipe damage due to excessive movement of the limiting wheel. In addition, under the elastic force of the elastic element, the positioning shaft can drive the limiting wheel to stably abut against the pipe. Moreover, when the pipe is irregularly shaped, the limiting wheel can maintain continuous contact with the outer wall of the pipe during the expansion and contraction of the elastic element, thereby improving the working stability and applicability of the limiting wheel during use.

[0019] Preferably, the positioning shaft is provided with an abutment rod, and the inner side wall of the moving groove is provided with a trigger switch, which is located on the side of the positioning shaft away from the pipe; the trigger switch is used to control the power supply of the moving motor, and when the abutment rod presses against the trigger point of the trigger switch, the moving motor is de-energized.

[0020] By adopting the above technical solution, when the moving block drives the limit wheel to abut the pipe fitting, the positioning shaft applies pressure to the elastic element, causing the elastic element to deform and contract. The positioning shaft also drives the contact rod to gradually approach the trigger switch. By pressing the trigger point of the trigger switch with the contact rod, the moving motor is de-energized, thereby realizing the timely stopping of the moving block and reducing the occurrence of pipe fitting damage caused by excessive movement of the moving block.

[0021] Preferably, a workbench is provided on one side of the support platform, a material rack is rotatably mounted on the workbench, and a material transfer motor for driving the material rack to rotate is provided on the workbench; pneumatic fingers are provided on the material rack, and a clamping plate for clamping pipe fittings is provided at the output end of the pneumatic fingers; a lifting component for driving the pneumatic fingers to move closer to or away from the support platform is provided on the material rack.

[0022] By adopting the above technical solution, the pneumatic fingers are controlled to clamp the pipe wall of the fitting, the material transfer motor is controlled to drive the material rack to rotate, so that the fitting to be processed is moved above the docking wheel. The output end of the lifting component is controlled to extend, and the pneumatic fingers are controlled to drive the clamping plate to release the clamping plate from the fitting, so as to realize the rapid loading of the fitting. After the fitting is flanging, the output end of the lifting component is controlled to extend, and the pneumatic fingers are used to control the clamping plate to clamp the pipe wall of the fitting. The rotation of the material rack is used to make the fitting disengage from the clamping wheel assembly. The lifting component is used to make the fitting disengage from the support platform, thereby realizing the rapid unloading of the fitting. This achieves rapid loading and unloading of the fitting for flanging, further simplifying the flanging process and improving the convenience of the flanging process.

[0023] Preferably, a conveyor for transporting pipe fittings is provided on the side of the workbench away from the support platform. Limiting plates are provided on both sides of the conveyor in the width direction, and a positioning baffle is provided at the end of the conveyor in the transport direction. A guide plate is rotatably provided on each of the limiting plates, and a gap is left between the two guide plates for a single pipe fitting to pass through. An abutting screw is threadedly connected to each of the limiting plates, and the abutting screw abuts against the guide plate.

[0024] By adopting the above technical solution, during the transportation of pipe fittings by the conveyor, the guide plates guide the pipe fittings, allowing them to pass through the gaps between the guide plates and thus positioning the pipe fittings along the width direction of the conveyor frame. By utilizing the abutment between the pipe fittings and the positioning baffles, the pipe fittings slip against the conveyor, achieving positioning along the length direction of the conveyor. This enables rapid positioning of the pipe fittings to be processed, facilitating mechanical feeding and improving the convenience of pipe fitting flanging. Furthermore, by screwing the abutment screw, the length of the abutment screw between the two sets of limiting plates is adjusted. The abutment screw abuts against the guide plates, quickly adjusting the gap between the two sets of guide plates, facilitating the processing of pipe fittings of different diameters and improving the practicality and economic applicability of the overall device.

[0025] Secondly, this application provides a method of using a stamping device for forming a metal flange, comprising the following steps:

[0026] Loading: Place the pipe fitting on the support platform and place the end of the pipe fitting to be processed inside the clamping wheel set;

[0027] Clamping: Controlling the clamping wheel assembly to clamp the part of the pipe fitting to be processed;

[0028] Flanging: The pipe fitting is rotated by a rotating component, and the clamping wheel group is driven by a rotating assembly to rotate the end of the pipe fitting relative to the bearing platform.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. By setting up a clamping wheel set to clamp the pipe wall at the position to be flanged; by driving the pipe to rotate through the rotating component, and by driving the clamping wheel set to rotate the pipe wall at the clamping position through the rotating assembly, the flanged processing of the pipe is realized quickly and conveniently, simplifying the snap-fit ​​steps in the traditional flanged processing of pipes, and facilitating flanged processing of pipes with various inner diameters.

[0031] 2. By setting a moving motor, rotating screw and moving block, the relative position of the limiting wheel and the pipe fitting can be adjusted, which makes it easier for the limiting wheel to limit pipe fittings of different diameters and reduces the phenomenon of the pipe fittings detaching from the mating wheel and the pressing wheel during the flange processing.

[0032] 3. By setting up material racks, transfer motors, lifting components, and pneumatic fingers to work together, the pipe fittings can be quickly loaded and unloaded; by setting up conveyors to transport the pipe fittings, and using guide plates and positioning baffles to position the pipe fittings, the pipe fittings can be mechanically loaded, thereby improving the convenience of pipe fitting flanging processing.

[0038] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0039] This application discloses a stamping device for forming metal flanges, which improves the convenience of flange processing for pipe workpieces.

[0040] Reference Figure 1 and Figure 2 A stamping device for forming metal flanges includes a support platform 1 for supporting a pipe fitting 101. In this embodiment, the pipe fitting 101 is a cylindrical pipe workpiece. A rotating assembly 3 is installed on the side wall of the support platform 1. The rotating assembly 3 includes a rotating rod 31 and a rotating motor 32. The rotating rod 31 is rotatably mounted on the side wall of the support platform 1 via a support rod. The rotating motor 32 is fixedly mounted on the support platform 1, and the output end of the rotating motor 32 is connected to the rotating rod 31 via a coupling to drive the rotating rod 31 to rotate relative to the support platform 1.

[0041] Reference Figure 1 and Figure 2 A clamping wheel assembly 2 is mounted on the rotating rod 31. The clamping wheel assembly 2 includes a mounting frame 21, a docking wheel 22, a sliding block 23, a pressing wheel 24, and a driving component 25. In this embodiment, the driving component 25 is a driving cylinder. The mounting frame 21 is welded and fixed to the rotating rod 31, and the docking wheel 22 is rotatably mounted on the mounting frame 21. A filter ring groove is formed on the peripheral wall of the docking wheel 22 so that the pipe wall at the end of the pipe fitting 101 can abut against it. A clearance notch 10 is formed on the side wall of the support platform 1 so that the docking wheel 22 can pass through, thereby reducing the portion of the pipe fitting 101 exposed on the support platform 1.

[0042] Reference Figure 1 and Figure 2A rotating component 20 is fixedly connected to the mounting bracket 21. In this embodiment, the rotating component 20 is a motor. In this embodiment, the output end of the rotating component 20 is connected to the docking wheel 22 via a coupling to drive the docking wheel 22 to rotate.

[0043] Reference Figure 1 and Figure 2 The sliding block 23 is slidably connected inside the mounting bracket 21, and the sliding block 23 is located on the side of the docking wheel 22 away from the bearing platform 1. The pressure wheel 24 is rotatably connected to the sliding block 23, and the driving component 25 is fixedly connected to the mounting bracket 21, and the output end of the driving component 25 is fixedly connected to the sliding block 23.

[0044] Reference Figure 1 and Figure 2 When the output end of the control drive 25 extends, it can drive the pressure roller 24 to gradually approach the docking roller 22, so that the pressure roller 24 and the docking roller 22 clamp the pipe wall of the pipe fitting 101. At this time, when the rotating member 20 drives the docking roller 22 to rotate, the pressure roller 24 can drive the pipe fitting 101 to rotate. Furthermore, when the output end of the drive 25 retracts, it can drive the pressure roller 24 to gradually move away from the docking roller 22, so that the pressure roller 24 and the docking roller 22 disengage from clamping the pipe fitting 101.

[0045] Reference Figure 2 and Figure 3 A rotating lead screw 13 is rotatably mounted on the bottom of the support platform 1. A moving block 4 is threaded onto the rotating lead screw 13 and abuts against the bottom wall of the support platform 1. A moving motor 14 is mounted on the bottom of the support platform 1. The output end of the moving motor 14 is keyed to the end of the rotating lead screw 13 to drive the rotating lead screw 13 to rotate, thereby driving the moving block 4 to move along the length of the rotating lead screw 13.

[0046] Reference Figure 2 and Figure 3 A positioning shaft 11 is mounted on the side wall of the movable block 4 facing the support platform 1. A sliding opening 12 is provided through the support platform 1 along its thickness direction for the positioning shaft 11 to pass through, and the length direction of the sliding opening 12 is parallel to the length direction of the rotating lead screw 13. The end of the positioning shaft 11 away from the movable block 4 passes through the sliding opening 12, and a limiting wheel 111 is rotatably connected to the positioning shaft 11. The peripheral wall of the limiting wheel 111 abuts against the outer peripheral wall of the pipe fitting 101, and an movable gap 1111 is left between the limiting wheel 111 and the upper surface of the support platform 1 to allow the flange of the pipe fitting 101 to pass through.

[0047] Reference Figure 2 and Figure 3The side wall of the movable block 4 has a movable groove 41 for the positioning shaft 11 to abut, and the length direction of the movable groove 41 is parallel to the length direction of the rotating lead screw 13, so that the positioning shaft 11 can slide inside the movable groove 41. A guide rod 42 is fixedly installed inside the movable groove 41 along its length direction, and the guide rod 42 passes through the positioning shaft 11 to guide the movement path of the positioning shaft 11.

[0048] Reference Figure 2 and Figure 3 An elastic element 43 is sleeved on the guide rod 42. In this embodiment, the elastic element 43 is a spring, and the elastic element 43 is located on the side of the positioning shaft 11 away from the tube 101. One end of the elastic element 43 is glued to the positioning shaft 11 along its length, and the other end of the elastic element 43 is glued to the inner wall of the moving groove 41.

[0049] Reference Figure 2 and Figure 3 When the moving block 4 drives the positioning shaft 11 and the limiting wheel 111 to gradually approach the pipe fitting 101, the limiting wheel 111 abuts against the pipe fitting 101. At this time, the elastic element 43 on the positioning shaft 11 deforms and contracts under pressure, causing the positioning shaft 11 to move along the length direction of the guide rod 42. Under the influence of the force of the elastic element 43, the positioning shaft 11 causes the limiting wheel 111 to abut against the outer peripheral wall of the pipe fitting 101. In addition, it also reduces the phenomenon that the moving block 4 drives the limiting wheel 111 to move too much, causing the limiting wheel 111 to press against the pipe fitting 101 and damage it.

[0050] Reference Figure 2 and Figure 3 A trigger switch 45 is fixedly installed on the inner wall of the moving groove 41, and the trigger switch 45 is located on the side of the positioning shaft 11 away from the pipe fitting 101. In this embodiment, the trigger switch 45 is electrically connected to the moving motor 14, so that the trigger switch 45 can control the power supply to the moving motor 14 by pressing its own trigger point. A contact rod 44 is threadedly connected to the positioning shaft 11 for touching the trigger point of the trigger switch 45.

[0051] Reference Figure 2 and Figure 3 When the moving block 4 drives the limiting wheel 111 to abut the pipe fitting 101, the positioning shaft 11 applies pressure to the elastic element 43, causing the elastic element 43 to deform and contract. The positioning shaft 11 also drives the abutment rod 44 to gradually approach the trigger switch 45. By pressing the trigger point of the trigger switch 45 with the abutment rod 44, the moving motor 14 is de-energized, thus achieving timely stopping of the moving block 4.

[0052] Reference Figure 1 and Figure 3A workbench 5 is installed on the ground on one side of the support platform 1, and a material rack 51 is rotatably installed on the workbench 5. A transfer motor 52 is installed on the workbench 5, and the output end of the transfer motor 52 is connected to the material rack 51 for transmission, so that the material rack 51 can be driven to rotate by the transfer motor 52.

[0053] Reference Figure 1 and Figure 3 A lifting component 55 is fixedly installed on the material rack 51. In this embodiment, the lifting component 55 is a lifting cylinder. The output end of the lifting component 55 passes through the material rack 51 and is fixedly connected to a pneumatic finger 53. The output end of the pneumatic finger 53 is fixedly connected to a clamping plate 54 by bolts to facilitate clamping the pipe 101.

[0054] Reference Figure 1 and Figure 3 A conveyor 6 is installed on the ground on the side of the workbench 5 away from the support platform 1. In this embodiment, the conveyor 6 can be a belt conveyor for transporting the pipe fitting 101. Limiting plates 61 are welded and fixed on both sides of the conveyor frame in the width direction, and a positioning baffle 62 is welded and fixed at the end of the conveyor 6 along the transport direction. The positioning baffle 62 abuts against the pipe fitting 101 to position the pipe fitting 101.

[0055] Reference Figure 1 and Figure 3 The two sets of limiting plates 61 are rotatably connected to the side walls of each other. Each set of limiting plates 61 is threaded with an abutting screw 611. The end of the abutting screw 611 abuts against the side wall of the guide plate 63 away from the pipe fitting 101, thereby limiting the maximum gap between the two sets of guide plates 63, so that a gap is left between the two sets of guide plates 63 for only a single pipe fitting 101 to pass through.

[0056] Reference Figure 1 and Figure 3 During the transport of pipe fitting 101 by conveyor 6, the moving pipe fitting 101 abuts against guide plate 63 and gradually passes through the gap between guide plates 63, thereby restricting the position of pipe fitting 101 along the width direction of conveyor 6. Then, pipe fitting 101 abuts against positioning baffle 62, restricting the position of pipe fitting 101 along the length direction of conveyor 6, thereby achieving rapid positioning of the pipe fitting 101 to be processed, so as to facilitate mechanical feeding.

[0057] The implementation principle of a stamping device for forming a metal flange according to an embodiment of this application is as follows:

[0058] The pipe fitting 101 is placed on the support platform 1, with a portion of the pipe fitting 101 extending out of the support platform 1, and the pipe wall of the end of the pipe fitting 101 to be processed is placed inside the transition annular groove on the docking wheel 22. The output end of the control drive unit 25 extends, causing the pressure wheel 24 to gradually approach the docking wheel 22, so that the pressure wheel 24 and the docking wheel 22 clamp the pipe fitting 101.

[0059] The rotating component 20 is activated, causing the pressure roller 24 to drive the pipe fitting 101 to rotate. Simultaneously, the rotating motor 32 drives the rotating rod 31 to rotate, which in turn drives the mounting bracket 21, the docking wheel 22, and the pressure roller 24 to rotate. This causes the pipe fitting 101 to rotate while the docking wheel 22 and the pressure roller 24 clamp a portion of the pipe wall, thus enabling convenient flanging of the pipe fitting 101. This simplifies the traditional flanging process and facilitates flanging of pipe fittings 101 with various inner diameters.

[0060] This application also discloses a method for using a stamping device to form a metal flange, comprising the following steps:

[0061] Loading: Place the pipe fitting 101 on the support platform 1, extend a portion of the pipe fitting 101 out of the support platform 1, and place the pipe wall of the part of the pipe fitting 101 to be processed inside the clamping wheel set 2;

[0062] Clamping: The clamping wheel set 2 is used to clamp the pipe wall of the protruding area of ​​the pipe fitting 101;

[0063] Flanging: The rotating component 20 drives the pipe 101 on the clamping wheel assembly 2 to rotate; then the rotating component 3 controls the clamping wheel assembly 2 to drive the pipe wall it clamps to rotate against the support platform 1, thereby realizing the flanging treatment of the pipe 101.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
