Description

Technical Field

[0001] The invention belongs to the technical field of pipe processing equipment, in particular to a pipe bending and expanding integrated pipe processing device. Background Art

[0002] As a common pipe connector, elbows are typically welded to pipes to create a bend in the media transport path. To improve the sealing effect between the elbow and the pipe, the elbow port must first be flared. The pipe end is then inserted into the flared port for welding to ensure weld tightness and stability throughout the entire pipeline.

[0003] Compared with the flaring of straight pipes, the flaring of bent pipes cannot directly expand the diameter of the pipe mouth by inserting a thick pipe. Usually, two balls, one large and one small, are required. By pushing, the large ball is driven to roll and squeeze the inner wall of the bent pipe, thereby realizing the flaring of the bent pipe. In order to ensure that the small ball can be aligned with the center position of the large ball, manual correction of the docking is required when the large ball is subsequently squeezed by docking. This may cause damage to the operator's hands during stamping, which may easily cause production accidents. Therefore, an integrated pipe bending and expanding equipment is needed. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting a technical solution: a pipe bending and expanding integrated pipe fitting processing device, comprising: Expanding elbow, placing metal shaping balls inside the expanding elbow, using the squeezing force of the shaping balls on the inner wall of the expanding elbow to expand the inner diameter of the elbow, The pipe clamping parts are in two sets and are used to clamp the outer surface of the expansion elbow; The external control component is used to control the movement of the pipe clamping component and expand the inner wall of the expansion elbow; The pipe clamping component comprises: A tube clamp container, wherein an external baffle is provided at the axis center of the upper portion of the tube clamp container, and a through guide opening is provided at the axis center of the inner cavity of the external baffle, and the through guide opening extends to the outside of the tube clamp container. The tube clamp containers on both sides can be used together during operation to form a container adapted to the bent pipe, thereby sealing the bent pipe inside the container; A built-in magnetic ring, wherein the built-in magnetic ring is arranged in the inner cavity of the tube clamp container through an embedded groove; An arc-shaped receiving groove is provided on one side of the inner cavity of the tube clamp container, and a straight guide groove is provided on the other side of the inner cavity of the tube clamp container. A built-in magnetic ring is arranged near the arc-shaped receiving groove, and the metal bent tube can be temporarily attached to the arc-shaped receiving groove without manual support through magnetic attraction. The external control component includes: A plug-in rotary drum, wherein the two ends of the inner cavity of the plug-in rotary drum are symmetrically provided with adapting slots; A force-applying plate is provided in the middle of the plug-in rotating drum, a side of the force-applying plate is provided with a bending arm, and a thrust ball is installed at the bottom end of the bending arm; The torque motor has an outer surface fixedly connected to a guide base plate through a fixed connecting plate. The torque motor drives the plug-in rotating drum to rotate along its axis through its plug rod, thereby pushing the shaping ball along the inner wall of the bent pipe through the bending force arm and the thrust ball. After the shaping ball sweeps across the inner wall of the bent pipe, it slides out from the bottom end of the bent pipe.

[0005] Furthermore, the tube clamping component further includes: A side pressure cylinder, wherein the axis center of the inner wall of the side pressure cylinder is sleeved with the outer surface of the plug-in rotating cylinder; A compression connecting tube, one side of the outer surface of the compression connecting tube is fixedly connected to the outer surface of the side pressure cylinder, and the other side of the outer surface of the compression connecting tube is fixedly connected to the outer surface of the external baffle, and the side surface of the side pressure cylinder extends to the interior of the compression connecting tube through the exchange port. The side pressure cylinder is fixed at the farthest end position of the plug-in rotating cylinder. By pressurizing or depressurizing the interior of the compression connecting tube, the length of the compression connecting tube is controlled so that the compression connecting tube can pull the tube clamping container to slide horizontally.

[0006] The tube clamping component further includes: The ball clamping component is arranged inside the tube clamping container through a straight guide groove and is used to clamp the plastic ball that slides out of the expansion elbow; A guide collar is provided at the top of the arc-shaped receiving groove and is used to initially stabilize the shaping ball; The upper surface of the guide base plate is evenly provided with guide slide bars, and the lower surface of the tube clamping container is slidably connected to the outer surface of the guide slide bar through the guide groove. The tube clamping container slides directionally along the guide slide bar, thereby ensuring that the tube clamping containers on both sides are accurately docked.

[0007] Furthermore, the force applying plate includes: The counterweight box has a plug pin at the bottom of the inner cavity of the counterweight box, and the bottom end of the plug pin is plugged into the middle of the outer surface of the plug-in drum. The counterweight box is an important force point for the shaping ball and is made of alloy steel; An inner pressure plate, the outer surface of which is arranged on a side of the inner wall of the counterweight box close to the bending arm; The top of the inner communicating tube is plugged into the pressure surface of the inner pressure plate through the docking interface, and the bottom end of the inner communicating tube is fixedly connected with a compression sleeve, and the compression sleeve is arranged inside the bending force arm, and the bottom end of the compression sleeve is fixedly connected to the outer surface of the thrust ball. When the bending force arm pushes the internal plastic ball, the plastic ball will generate a reaction force on the compression sleeve inside the bending force arm through the thrust ball. At this time, the compression sleeve will pressurize the pressure-sensitive surface of the inner pressure plate through the inner communicating tube, so that the inner pressure plate can judge whether the internal plastic ball is blocked and cannot move according to the pressure it receives. When the plastic ball is stuck in the inside of the bent pipe, the reaction force received by the inner pressure plate will continue to increase due to the continuous pressure of the torque motor. When it exceeds the safety threshold set, it is necessary to stop pressurizing. When the plastic ball can slide smoothly along the inner wall of the bent pipe, the reaction force received by the inner pressure plate will not increase to its threshold, and the pipe expansion work can be carried out safely at this time.

[0008] Furthermore, the guide collar includes: An arc-shaped shell, wherein the lower surface of the arc-shaped shell is fixedly connected to the upper surface of the guide base plate, and the inner cavity of the arc-shaped shell is uniformly provided with through openings; An inner wall pad, the outer surface of which is fixedly connected to the inner wall of the arc-shaped shell, the portion of the inner wall pad close to the inner wall of the arc-shaped shell being a hard plate structure, the outer portion of which is a hollow eardrum; An independent pressure pump, the outer surface of the independent pressure pump is fixedly connected to the outer surface of the curved shell, the exhaust port of the independent pressure pump is fixedly connected to a built-in connecting pipe, and the built-in connecting pipe extends to the interior of the inner wall pad at one end away from the independent pressure pump. The independent pressure pump can pressurize the interior of the inner wall pad to expand the eardrum of each inner wall pad, thereby reducing the actual inner diameter of the curved shell after docking, and further strengthening the top end of the bent pipe.

[0009] Furthermore, the ball clamping component includes: A wall-attached air pressure box, the outer surface of which is slidably connected to the outer surface of the tube-clamping container; A slide rod outer box, the outer surface of which is fixedly connected to the outer surface of the clamping tube container; A connecting straight rod, the outer surface of which is slidably connected to the inner cavity of the sliding rod outer box, the front end of which is plugged into the outer surface of the wall-attached air pressure box, and the rear end of which is sleeved with an anti-shelling device.

[0010] Furthermore, the ball clamping component further includes: an inner curved slide, wherein the outer surface of the inner curved slide is slidably connected to the inner wall of the tube clamp container via a straight guide groove, and the middle portion of the outer surface of the inner curved slide extends to the outside of the tube clamp container via the straight guide groove; An expansion inner pad is arranged at the axis center of the inner cavity of the inner arc skateboard, and both sides of the expansion inner pad are fixedly connected to the inner wall of the inner arc skateboard. The connection port of the wall-attached air pressure box is fixedly connected to the inner cavity of the inner arc skateboard. When the wall-attached air pressure box pressurizes the interior of the inner arc skateboard, the expansion inner pad of the inner arc skateboard begins to bulge outward, clamping the plastic ball that slides out from the inner wall of the bent pipe.

[0011] The beneficial effects of the present invention are as follows: 1. The device can drive the bending arm and the thrust ball through the torque motor to pressurize the plastic ball inside the expansion elbow, thereby realizing the expansion of the inner wall of the elbow. Since the bending arm rotates with the axis of the plug-in rotary drum, the thrust ball can always face the plastic ball and perform thrust extrusion movement. There is no need to manually adjust the extrusion point of the plastic ball, so it can effectively avoid the problem of extrusion injury to workers who adjust the angle during stamping, thereby achieving the purpose of safe production.

[0012] 2. The device can fix the expansion elbow in the reserved arc-shaped receiving groove through the tube clamping containers docked on both sides, thereby achieving the effect of limiting the expansion elbow and preventing the expansion elbow from slipping due to the strong squeezing effect of the shaping ball. The sealed tube clamping container can isolate the tube body from the outside world, thereby preventing the tube body from being damaged or cracked due to the extrusion process, causing tube fragments to splash to the outside and cause injury.

[0013] 3. During the merging process of the tube clamp containers, in order to avoid the shaking of the tube body when it moves, which causes the tube clamp containers on both sides to be unable to perfectly wrap the tube body inside the arc-shaped receiving groove when merging, the expansion elbow is simply fixed in the arc-shaped receiving groove by means of a built-in magnetic ring, and a straight guide groove is provided to reserve sufficient space at the bottom of the tube body. The straight guide groove can also provide a sliding area for the plastic balls pushed out of the tube body, so that the pushed plastic balls can be temporarily stored inside the straight guide groove, thereby avoiding the problem that the heavier plastic balls roll out directly from the tube clamp container and hit the ground, causing damage to the ground.

[0014] 4. In the process of the force plate applying pressure to the bending lever arm, the thrust ball at the bottom of the bending lever arm will press the compression sleeve due to the reaction force of the shaping ball, and then the compression sleeve will pressurize the internal pressure plate through the internal connecting tube inside the bending lever arm. Since the reaction force on the thrust ball is relatively large, in order to avoid damage to the internal pressure plate due to excessive pressure, the compression sleeve is used to apply pressure instead of the bending lever arm to directly squeeze the internal pressure plate, thereby greatly reducing the reaction force on the internal pressure plate and effectively protecting the pressure plate.

[0015] 5. Since the bending force arm exerts a large thrust on the shaping ball, when the shaping ball escapes from the bottom of the tube body, the bending force arm is still applying pressure, and the shaping ball will slide out of the straight guide groove with a large acceleration, which is easy to hit the inner wall of the device and relevant personnel outside, which is more dangerous. Therefore, an inner arc slide is provided at the straight guide groove, and the shaping ball is clamped by the expansion inner pad inside the inner arc slide, thereby slowing down and buffering the shaping ball, and driving the shaping ball to slide out of the straight guide groove, realizing the transfer of the shaping ball from the inside to the outside.

DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0019] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a pipe bending and expanding integrated pipe fitting processing device, comprising: Expand the elbow 5. Place a metal plastic ball inside the expanded elbow 5. Use the squeezing force of the plastic ball on the inner wall of the expanded elbow 5 to expand the inner diameter of the elbow. The pipe clamping parts 2, which are in two groups, are used to clamp the outer surface of the expansion elbow 5; The external control component 1 is used to control the movement of the pipe clamping component 2 and expand the inner wall of the expansion elbow 5; The tube clamping component 2 includes: The clamp tube container 21 has an external baffle 22 disposed at the axis center of the upper portion of the clamp tube container 21. A through-guide opening is provided at the axis center of the inner cavity of the external baffle 22, and the through-guide opening extends to the outside of the clamp tube container 21. The clamp tube containers 21 on both sides can be used together during operation to form a container adapted for the bent tube, thereby sealing the bent tube inside the container. A built-in magnetic ring 26 is provided in the inner cavity of the tube clamp container 21 through an embedded groove; An arc-shaped receiving groove 25 is formed on one side of the inner cavity of the tube clamp container 21, and a straight guide groove 23 is formed on the other side of the inner cavity of the tube clamp container 21. A built-in magnetic ring 26 is arranged near the arc-shaped receiving groove 25. Through magnetic attraction, the metal bent tube can be temporarily attached to the arc-shaped receiving groove 25 without manual support. The external control component 1 includes: The plug-in rotating drum 14 has symmetrically opened adapting slots at both ends of the inner cavity of the plug-in rotating drum 14; The force-applying plate 4 is arranged in the middle of the plug-in rotating drum 14. A bending arm 15 is provided on the side of the force-applying plate 4, and a thrust ball 16 is installed at the bottom end of the bending arm 15. The torque motor 13, the outer surface of the torque motor 13 is fixedly connected to the guide base plate 11 through a fixed connecting plate. The torque motor 13 drives the plug-in rotating drum 14 to rotate along the axis through its plug rod, thereby pushing the shaping ball along the inner wall of the bent pipe through the bending force arm 15 and the thrust ball 16. After the shaping ball sweeps across the inner wall of the bent pipe, it slides out from the bottom end of the bent pipe.

[0020] The tube clamping component 2 further includes: The side pressure cylinder 27, the axis of the inner wall of the side pressure cylinder 27 is sleeved with the outer surface of the plug-in rotating cylinder 14; The compression connecting tube 29 has one side of its outer surface fixedly connected to the outer surface of the side pressure cylinder 27, and the other side of its outer surface fixedly connected to the outer surface of the external baffle 22. The side surface of the side pressure cylinder 27 extends to the interior of the compression connecting tube 29 through the exchange port 28. The side pressure cylinder 27 is fixed at the farthest end of the plug-in rotating cylinder 14. By pressurizing or depressurizing the interior of the compression connecting tube 29, the length of the compression connecting tube 29 is controlled so that the compression connecting tube 29 can pull the tube clamping container 21 to slide horizontally.

[0021] The tube clamping component 2 further includes: The ball clamping component 3 is arranged inside the tube clamping container 21 through a straight guide groove 23 and is used to clamp the plastic ball that slides out of the expansion elbow 5; A guide collar 6 is provided at the top of the arc-shaped receiving groove 25 and is used to initially stabilize the plastic ball; The upper surface of the guide base plate 11 is evenly provided with guide slides 12. The lower surface of the tube clamping container 21 is slidably connected to the outer surface of the guide slide 12 through the guide groove 24. The tube clamping container 21 slides along the guide slide 12 in a direction, thereby ensuring that the tube clamping containers 21 on both sides are accurately docked.

[0022] Before using the device to expand a bent pipe, the bent pipe to be processed is first placed inside the pipe clamping component 2, and the pipe clamping containers 21 on both sides are pulled apart. At this time, the side pressure cylinders 27 on both sides pressurize the inside of the compression connecting tube 29, shortening the compression connecting tube 29, thereby pulling the pipe clamping containers 21 away from the center and pulling the pipe clamping containers 21 on both sides apart.

[0023] The operator places the bent pipe directly into the arc-shaped receiving groove 25 of the pipe clamping container 21 on either side, as shown in FIG. Figure 3 As shown, taking the right-side clamping container 21 as an example, after the expansion bend 5 is placed, since a built-in magnetic ring 26 is provided around the arc-shaped receiving groove 25, the metal expansion bend 5 can be temporarily fixed after being directly placed in the arc-shaped receiving groove 25. Subsequently, the compression connecting pipes 29 on both sides push the corresponding clamping container 21 toward the middle. After the clamping containers 21 on both sides are docked and clamped, a shaping ball is added to the top of the expansion bend 5. Since the outer diameter of the shaping ball is slightly larger than the inner diameter of the expansion bend 5, the shaping ball will be stuck on the top of the expansion bend 5 at this time.

[0024] After the shaping ball is placed, the torque motors 13 on both sides rotate the force-applying plate 4 by twisting the plug-in rotating drum 14 counterclockwise. At this time, the force-applying plate 4 pressurizes the shaping ball on the top of the expansion bend 5 through the bending arm 15 and the thrust ball 16, and then pushes the shaping ball into the interior of the expansion bend 5. The squeezing force of the shaping ball is used to squeeze the inside of the bend, so that the inner diameter of the bend is increased to the same value as the outer diameter of the shaping ball.

[0025] When the thrust ball 16 pushes the shaping ball out from the bottom of the expansion bend 5, it means that the expansion of the expansion bend 5 is completed. At this time, the plug-in rotating cylinder 14 is twisted clockwise to extract the bending arm 15 and the thrust ball 16 from the inside of the expansion bend 5. Then, the rolled-out shaping ball is recovered through the straight guide groove 23, and then the tube clamping container 21 is opened to take out the expansion bend 5. If there is a subsequent bend to be expanded, continuous processing can be achieved by replacing the subsequent processed bend.

[0026] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: Based on embodiment 1, the force-applying plate 4 includes: The counterweight box 41 has a plug pin 42 at the bottom of the inner cavity of the counterweight box 41. The bottom end of the plug pin 42 is plugged into the middle of the outer surface of the plug drum 14. The counterweight box 41 is an important force point for shaping the ball and is made of alloy steel. An inner pressure plate 43, the outer surface of which is arranged on the inner wall of the counterweight box 41 near the bending arm 15; The top of the internal communicating tube 44 is plugged into the pressure surface of the internal pressure plate 43 through the docking interface, and the bottom end of the internal communicating tube 44 is fixedly connected to a compression sleeve 45, which is arranged inside the bending arm 15. The bottom end of the compression sleeve 45 is fixedly connected to the outer surface of the thrust ball 16. When the bending arm 15 pushes the internal plastic ball, the plastic ball will generate a reaction force on the compression sleeve 45 inside the bending arm 15 through the thrust ball 16. At this time, the compression sleeve 45 will pass through the internal communicating tube 44. The pressure-sensitive surface of the inner pressure plate 43 is pressurized so that the inner pressure plate 43 can judge whether the plastic ball inside is blocked and cannot move based on the pressure it receives. When the plastic ball is stuck inside the curved pipe, the torque motor 13 is continuously applying pressure, and the reaction force on the inner pressure plate 43 will continue to increase. When it exceeds the safety threshold set, the pressure needs to be stopped. When the plastic ball can slide smoothly along the inner wall of the curved pipe, the reaction force on the inner pressure plate 43 will not increase to its threshold, and the pipe expansion work can be carried out safely at this time.

[0027] The guide collar 6 comprises, The arc-shaped shell 61 has a lower surface fixedly connected to the upper surface of the guide base plate 11, and the inner cavity of the arc-shaped shell 61 is uniformly provided with through openings; The inner wall pad 64 has an outer surface fixedly connected to the inner wall of the arc-shaped shell 61. The portion of the inner wall pad 64 close to the inner wall of the arc-shaped shell 61 is a hard plate structure, and the outer portion of the hard plate is a hollow eardrum; An independent pressure pump 62, the outer surface of the independent pressure pump 62 is fixedly connected to the outer surface of the arc shell 61, and the exhaust port of the independent pressure pump 62 is fixedly connected to a built-in connecting pipe 63, and the built-in connecting pipe 63 extends from one end of the independent pressure pump 62 to the interior of the inner wall pad 64. The independent pressure pump 62 can pressurize the interior of the inner wall pad 64 to expand the eardrum of each inner wall pad 64, thereby reducing the actual inner diameter of the arc shell 61 after docking, and further strengthening the top end of the bend.

[0028] The ball clamping component 3 includes: The wall-attached air pressure box 31 has an outer surface that is slidably connected to the outer surface of the clamping tube container 21; A slide outer box 35, the outer surface of the slide outer box 35 is fixedly connected to the outer surface of the clamping tube container 21; The connecting straight rod 34 has its outer surface slidably connected to the inner cavity of the sliding rod outer box 35, its front end is plugged into the outer surface of the wall-attached air pressure box 31, and its rear end is sleeved with an anti-shelling device.

[0029] The ball clamping component 3 also includes: An inner curved slide 32, the outer surface of the inner curved slide 32 is slidably connected to the inner wall of the clamp tube container 21 through the straight guide groove 23, and the middle portion of the outer surface of the inner curved slide 32 extends to the outside of the clamp tube container 21 through the straight guide groove 23; The expansion inner pad 33 is arranged at the axis center of the inner cavity of the inner arc-shaped slide 32, and both sides of the expansion inner pad 33 are fixedly connected to the inner wall of the inner arc-shaped slide 32. The connection port of the wall-attached air pressure box 31 is fixedly connected to the inner cavity of the inner arc-shaped slide 32. When the wall-attached air pressure box 31 pressurizes the interior of the inner arc-shaped slide 32, the expansion inner pad 33 of the inner arc-shaped slide 32 begins to bulge outward, clamping the plastic ball that slides out from the inner wall of the bend.

[0030] During the process of the force-applying plate 4 applying pressure to the bending lever 15, the thrust ball 16 at the bottom of the bending lever 15 will press the compression sleeve 45 due to the reaction force of the shaping ball, and then the compression sleeve 45 will apply pressure to the internal sensing pressure plate 43 through the internal connecting tube 44 inside the bending lever 15. Since the reaction force exerted on the thrust ball 16 is relatively large, in order to prevent the internal sensing pressure plate 43 from being damaged due to excessive pressure, the compression sleeve 45 is used to apply pressure instead of the bending lever 15 to directly squeeze the internal sensing pressure plate 43, thereby greatly reducing the reaction force exerted on the internal sensing pressure plate 43.

[0031] After the shaping ball is placed on the top of the expansion bend 5, the shaping ball will be inside the arc shell 61, and then each independent pressure pump 62 outside the arc shell 61 will inflate the inner wall gasket 64 to expand the inner wall gasket 64. At this time, the inner wall gasket 64 will clamp the outer side of the shaping ball to temporarily stabilize the shaping ball, and in the process of the shaping ball being squeezed toward the inside of the expansion bend 5 by the thrust ball 16, since the shaping ball slides toward the inside of the expansion bend 5, the shaping ball will gradually be offset from the inner wall gasket 64 during the process of entering the expansion bend 5, so the inner wall gasket 64 will not clamp the shaping ball too tightly, causing the shaping ball to be unable to be pushed toward the inside of the tube body by the thrust ball 16.

[0032] When the shaping ball is about to slide out from the bottom of the expansion bend 5, the inner arc slide 32 is in contact with the bottom of the expansion bend 5, and then the wall-attached air pressure box 31 pressurizes the inside of the inner arc slide 32 to expand the expansion inner pad 33 in the middle. At this time, the expansion inner pad 33 is in close contact with the outer surface of the shaping ball, thereby clamping the shaping ball inside the inner arc slide 32, and then the sliding rod outer box 35 pushes the connecting straight rod 34 to slide the inner arc slide 32 forward, thereby driving the shaping ball to slide out from the straight guide groove 23, realizing the transfer of the shaping ball from the inside to the outside.

[0033] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
