Description

Technical Field

[0001] The present application relates to the field of flanging machines, and in particular to a pipe flanging machine. Background Art

[0002] In order to facilitate the disassembly and assembly of pipes and meet the requirements of connection strength and sealing, it is often necessary to flanging the end faces of pipes in the actual processing process of pipes. After the flanging is completed, the flanging can be used directly as a flange. The flanging of the two pipes to be connected can be directly welded or bolt holes can be opened and connected with bolts. It can also be used in conjunction with a slip-on movable flange.

[0003] At present, the flanging of pipes is generally completed automatically by flanging machines. During the specific operation, the fixed wheel and the movable wheel complete the clamping and driving of the pipe, so that the pipe can rotate between the fixed wheel and the movable wheel. When the fixed wheel and the movable wheel rotate at the same time, the flanging of the pipe can be achieved. By controlling the rotation angle of the fixed wheel and the movable wheel, the flanging effect of the pipe can be controlled to ensure that the flanging operation of the pipe can meet the design requirements.

[0004] In order to improve the stability of the pipeline during rotation, support wheels are set on the outside of the pipeline. However, during use, the existing support wheels will generate friction with the pipeline, thereby causing many scratches on the outer wall of the pipeline, reducing the quality of the finished pipeline. Utility Model Content

[0005] In order to improve the problem that scratches are easily generated on the outer wall of the pipe during the flanging process, the present application provides a pipe flanging machine.

[0006] This application provides a pipe flanging machine, which adopts the following technical solution:

[0007] A pipe flanging machine comprises a workbench and a turning mechanism arranged on the side wall of the workbench, wherein the turning mechanism is provided with a driving wheel and a flanging wheel, and the pipe is clamped between the driving wheel and the flanging wheel. A rotating motor for driving the driving wheel to rotate is provided below the workbench, and a cylinder for driving the flanging wheel to slide is provided on the outside of the turning mechanism; an auxiliary wheel is also provided on the workbench, and the outer side of the auxiliary wheel is wrapped with a rubber ring, the inner wall of the rubber ring is detachably connected to the outer wall of the auxiliary wheel, and the outer wall of the rubber ring is in contact with the outer wall of the pipe.

[0008] By adopting the above technical solution, the rubber ring is used to resist the pipe, and the rubber ring and the auxiliary wheel rotate synchronously, which ensures that the auxiliary wheel can improve the support force of the pipe while effectively preventing the auxiliary wheel from forming scratches on the surface of the pipe.

[0009] Optionally, the workbench is provided with a waist hole and an adjustment seat, the adjustment seat is provided with a bolt locked in the vertical direction, and the bolt can slide in the waist hole; a support rod is provided in the adjustment seat, and an auxiliary wheel is provided at both ends of the support rod, and the support rod can rotate in the adjustment seat, and any of the auxiliary wheels is in contact with the outer wall of the pipe.

[0010] By adopting the above technical solution, the position of the adjustment seat is first determined by the cooperation between the bolt and the waist hole, ensuring that the auxiliary wheel can reliably fit the pipeline, and then the two auxiliary wheels are alternately used by rotating the support rod, which facilitates the maintenance and care of the rubber ring on the auxiliary wheel.

[0011] Optionally, the adjustment seat is in the shape of an elongated strip, and a through slot is provided on the top of the adjustment seat, and the through slot passes through the through slot along the length direction of the adjustment seat, and the support rod is arranged in the adjustment seat, and the thickness of the support rod is less than the depth of the through slot; a spring and a support plate are provided in the through slot, one end of the spring is connected to the bottom of the through slot, and the other end of the spring is flush with the bottom of the support plate, and the top of the support plate supports the bottom of the support rod, one of the auxiliary wheels is arranged on one side of the top of the support rod, and the other auxiliary wheel is arranged on the other side of the top of the support rod.

[0012] By adopting the above technical solution, when the support rod is located in the through groove, the through groove will form a limiting effect on the support rod, preventing the support rod from rotating during the flanging process, thereby causing the auxiliary support function of the auxiliary wheel to fail.

[0013] Optionally, the tail of the bolt contacts the bottom of the workbench, the rod of the bolt extends upward and passes through the adjustment seat and the support rod in sequence, the rod of the bolt is adaptively screwed with a nut for pressing the support rod downward, and the rod of the bolt is slidably connected to the adjustment plate and the support rod.

[0014] By adopting the above technical solution, after loosening the nut, the adjustment seat can slide on the workbench along the extension direction of the waist hole, thereby adjusting the position of the adjustment seat and the auxiliary wheel, ensuring that the auxiliary wheel can provide reliable supporting force when flanging pipes with different outer diameters; after the nut is loosened, the spring pushes the support rod out of the through slot, allowing the support rod to rotate around the bolt, thereby interchangeable the positions of the two auxiliary wheels.

[0015] Optionally, the sum of the naturally extended length of the spring and the thickness of the supporting plate is not less than the depth of the through groove.

[0016] By adopting the above technical solution, it is ensured that after the nut is loosened, the spring has sufficient elastic force to push the support rod to the outside of the through groove, thereby ensuring that the support rod can be rotated and the position of the auxiliary wheel can be changed by moving the support rod.

[0017] Optionally, a gasket is provided on the top of the support rod, and the gasket is located between the support rod and the nut. A smooth portion is provided in the middle of the screw rod, and the nut and the gasket can slide up and down in the smooth portion.

[0018] By adopting this technical solution, the washer enhances the locking effect of the nut and prevents it from loosening. When the nut is screwed into the smooth portion, the spring quickly rebounds, enabling the support rod to be quickly lifted. When the nut again contacts the threads on the bolt, the nut stops moving, limiting the nut's displacement and preventing it from slipping off the bolt, making it easier to tighten the bolt again.

[0019] Optionally, the flipping mechanism includes a turntable, a rotating rod and a flipping motor, the turntable is connected to the middle of the rotating rod, the driving wheel and the flanging wheel are respectively located on both sides of the rotating rod, and the flipping motor is used to drive either end of the rotating rod to rotate.

[0020] By adopting the above technical solution, under the drive of the flip motor, the rotating rod can drive the turntable to rotate, so that the driving wheel and the flanging wheel can rotate simultaneously to achieve flanging of the pipe.

[0021] Optionally, a slide groove is provided in the middle of the turntable, and the cylinder is connected to the turntable, and the cylinder is used to push the flanging wheel towards or away from the driving wheel.

[0022] By adopting the above technical solution, the cylinder is connected to the turntable, so that the cylinder can rotate synchronously during the rotation of the turntable, thereby maintaining the driving action on the flanging wheel to be able to continue, thereby ensuring that there is sufficient clamping force between the driving wheel and the flanging wheel to achieve flanging of the pipe.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. A rubber sleeve is provided on the outer wall of the auxiliary wheel so that the auxiliary wheel does not directly contact the outer wall of the pipe, effectively preventing scratches from being formed on the outer wall of the pipe during the flanging process. At the same time, under the action of the rubber sleeve, the auxiliary wheel can maintain the supporting effect on the pipe, thereby realizing the flanging operation of the pipe in cooperation with the driving wheel and the flanging wheel.

[0025] 2. By adjusting the locking and loosening states of the bolts and nuts, the position of the adjustment seat can be fixed and adjusted, so that the auxiliary wheels can support pipes with different outer diameters. At the same time, the support rod on the adjustment seat can be rotated, so that the two auxiliary wheels on the support rod can alternately contact the outer wall of the pipe, which is convenient for maintenance of the rubber ring on the auxiliary wheel.

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] Figure 1 is a schematic three-dimensional diagram of this application, Figure 2 This is a schematic three-dimensional diagram of the flip mechanism. Figure 1 and Figure 2A pipe flanging machine includes a workbench 1 and a flipping mechanism 2 disposed on a side wall of the workbench 1. The flipping mechanism 2 includes a turntable 21, a flipping motor 23, and a rotating rod 22. The turntable 21 is connected to the middle portion of the rotating rod 22. The flipping motor 23 drives either end of the rotating rod 22 to rotate via a transmission structure, so that the turntable 21 can rotate synchronously with the rotating rod 22. The two rotating rods 22 are coaxially arranged and extend along the width of the workbench 1. A slide 210 is provided on the turntable 21 and extends along the length of the workbench 1. The turntable 21 is connected to one side of the rotating rod 22. A flanging wheel 4 is provided on the turntable 21. A cylinder 40 is provided on the outside of the turntable 21. The cylinder 40 pushes the flanging wheel 4 to slide in the slide groove 210 (the lower part of the flanging wheel 4 slides in the slide groove 210, and the upper part of the flanging wheel 4 is located on the outside of the slide groove 210). A driving wheel 3 driven by a rotating motor 30 is provided on the other side of the rotating rod 22. When the rotating rod 22 rotates, the driving wheel 3 and the flanging wheel 4 will rotate synchronously, thereby completing the flanging operation.

[0035] When flanging a pipe, the pipe is first placed on the workbench 1, with the driving wheel 3 aligned with the inner wall of the pipe. The cylinder 40 is then activated, causing the flanging wheel 4 to engage the outer wall of the pipe, thereby clamping the pipe. After the pipe is placed, the rotary motor 30 is activated, causing the driving wheel 3 to rotate. Because the pipe is clamped between the driving wheel 3 and the flanging wheel 4 (i.e., the driving wheel 3 is located on the inside of the pipe and aligned with the inner wall, while the flanging wheel 4 is located on the outside of the pipe and aligned with the outer wall), the driving wheel 3 drives the pipe to rotate as it rotates. After the pipe begins to rotate, the tilting motor 23 is activated, causing the rotating rod 22 and the turntable 21 to flip. Furthermore, because the tilting mechanism 2 is located outside the workbench 1, the majority of the pipe is aligned with the top of the workbench 1. As the driving wheel 3 and the flanging wheel 4 flip upward, they exert downward pressure on the pipe edge, causing it to bend, thus achieving the pipe flanging operation.

[0036] Figure 3 This is a reference diagram of the separation state of the workbench and the adjustment seat. Figure 4 This is a reference diagram of the assembly status of the adjustment seat and support rod. Figure 3 and Figure 4 The workbench 1 is also provided with a waist hole 11 and an adjustment seat 6. A bolt 12 is passed through the adjustment seat 6. The tail of the bolt 12 is located at the bottom of the workbench 1. The shaft of the bolt 12 passes through the adjustment seat 6 and is appropriately screwed with a nut 121. After loosening the nut 121, the adjustment seat 6 can be pushed to make the bolt 12 slide in the waist hole 11. Then, the nut 121 can be tightened to adjust the position of the adjustment seat 6. This facilitates reliable adjustment of the position of the adjustment seat 6 when flanging pipes with different outer diameters.

[0037] A through slot 61 is provided at the top of the adjustment seat 6. The through slot 61 extends along the length of the adjustment seat 6 and penetrates the adjustment seat 6. A support rod 7 is provided within the through slot 61. The thickness of the support rod 7 is less than the depth of the through slot 61. The support rod 7 also extends along the length of the adjustment seat 6, with both ends of the support rod 7 extending to the outside of the through slot 61. Auxiliary wheels 5 are provided on both sides of the top of the support rod 7. The outer edges of the auxiliary wheels 5 are located outside the ends of the support rod 7. In other words, when either auxiliary wheel 5 contacts the outer wall of the pipe, the end of the support rod 7 will move away from the outer wall of the pipe. With the support of the auxiliary wheels 5, the pipe can be more stably supported, ensuring that the pipe will not fall during the flanging process, thereby ensuring the stability of the flanging process.

[0038] See also Figure 4 A rubber sleeve 50 is wrapped around the outer wall of the auxiliary wheel 5. The inner wall of the rubber sleeve 50 is detachably connected to the outer wall of the auxiliary wheel 5. During the flanging process, the outer wall of the rubber sleeve 50 contacts the outer wall of the pipe. Thus, when friction occurs between the outer wall of the pipe and the auxiliary wheel 5, the rubber sleeve 50 does not leave scratches on the outer wall of the pipe, thus protecting the pipe and improving the quality of the flanging pipe.

[0039] Figure 5 This is a reference diagram of the exploded state of the adjustment seat and support rod. Figure 5 A plurality of springs 62 and a plurality of supporting plates 63 are disposed within the through-slot 61. The number of springs 62 matches the number of supporting plates 63. The springs 62 are spaced apart along the length of the through-slot 61. One end of the spring 62 is connected to the bottom of the through-slot 61, and the other end of the spring 62 is connected to the bottom of the supporting plate 63. The tops of the supporting plates 63 are flush with and in contact with the bottom of the support rod 7. In other words, the springs 62 and supporting plates 63 support the support rod 7. The bolt 12 passes through the through-slot 61 from the bottom of the adjustment seat 6 and passes through the middle of the support rod 7 as it extends upward. A washer 64 is also disposed at the top of the support rod 7, and a nut 121 presses against the top of the washer 64. When the nut 121 is rotated downward, it pushes the washer 64 and the support rod 7 upward. When the nut 121 is locked, the top of the support rod 7 is flush with the notch of the through slot 61, and the bottom of the washer 64 contacts the top of the adjustment seat 6. In this way, when the adjustment seat 6 is in the locked state, the support rod 7 is also limited in the through slot 61 and cannot rotate, thereby ensuring that one of the auxiliary wheels 5 on the support rod 7 is in close contact with the outer wall of the pipe. During the downward rotation of the nut 121, a pressure effect is exerted on the washer 64, and the force-bearing area of the washer 64 is larger than the force-bearing area of the nut 121, thereby making the locking effect of the nut 121 on the support rod 7 more reliable. At the same time, the interaction between the washer 64 and the nut 121 can prevent the nut 121 from loosening during the flanging process, further improving the locking effect of the nut 121 on the support rod 7.

[0040] Figure 6 is a schematic perspective view of a bolt. Figure 6 Combined with Figure 5 The rod of the bolt 12 is in sliding connection with the adjustment plate and the support rod 7. A smooth portion 122 is provided in the middle of the screw rod. When the nut 121 is rotated upward, the spring 62 will gradually rebound and push the support rod 7 toward the outside of the through-slot 61. When the nut 121 is screwed upward into the smooth portion 122, the spring 62 will quickly reset. Since the sum of the natural extension length of the spring 62 and the thickness of the support piece 63 is not less than the depth of the through-slot 61, after the spring 62 has released its energy, the support rod 7 is completely located outside the through-slot 61. After the nut 121 continues to move upward under the support of the spring 62 and contacts the nut 121 on the bolt 12, the nut 121 stops moving. In other words, the uppermost thread of the bolt 12 can limit the nut 121 and prevent it from separating from the bolt 12.

[0041] When the support rod 7 is lifted up by the springs 62, the adjustment seat 6 can be pressed to fix it, and then the support rod 7 can be rotated 180 degrees, so that the other auxiliary wheel 5 on the support rod 7 is rotated to a position close to the pipe, that is, the positions of the two auxiliary wheels 5 on the support rod 7 are interchanged. In this way, the rubber ring 50 on the auxiliary wheel 5 that is not in contact with the pipe can be replaced without affecting the supporting effect on the pipe, ensuring that under the protection of the rubber ring 50, no scratches will be left on the outer wall of the pipe after the pipe flanging is completed.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
