Description

Technical Field

[0001] The present invention relates to the technical field of pipe production equipment, and in particular to a pipe flanging device and pipe production equipment. Background Art

[0002] Self-rolling sleeve is a plastic sleeve used to cover wire harnesses. Self-rolling sleeves are different from other tubular structures. They are usually formed by spirally rolling a whole piece of fabric into a tubular structure and heating it. This makes it convenient for employees to protect the wire harnesses formed by multiple wires that have been arranged, and it also makes it convenient for the self-rolling sleeve to bend and other positional deformations.

[0003] However, since the self-rolling sleeve is not completely sealed, dust and other particles can easily enter the tube through the gaps between the self-rolling sleeves. Employees need to use cable ties or other additional methods to process the self-rolling tube to ensure the cleanliness of the wire harness inside the tube. Summary of the Invention

[0004] The main purpose of the present invention is to provide a pipe flanging device, aiming to solve the problem of poor sealing effect of self-rolling casing.

[0005] To achieve the above-mentioned object, the present invention provides a pipe flanging device for flanging a pipe, wherein the pipe has a first side and a second side, the second side covering the first side, and the pipe flanging device comprises:

[0006] Guiding structures; and

[0007] A shifting structure, the shifting structure being connected to one end of the guide structure, the shifting structure being provided with a shifting rod, the shifting rod and the guide structure being arranged at an angle;

[0008] The guide structure guides the tube to pass through the distribution structure, and the distribution rod turns the first side of the tube to the outside of the second side, so that the first side covers the second side.

[0009] In one embodiment, the shifting structure also includes a shift rod seat, the shift rod seat is connected to the guide structure, the shift rod is connected to the shift rod seat, and the shift rod is provided with a first limiting portion and a second limiting portion at intervals along the axial extension direction of the shift rod, the first limiting portion is used to limit the movement position of the first side, and the second limiting portion is used to limit the movement position of the second side.

[0010] In one embodiment, the shift lever is a cylindrical structure, the first limiting portion is a side surface of the cylindrical structure, and the second limiting portion is a groove located on the other side surface of the cylindrical structure facing away from the first limiting portion.

[0011] In one embodiment, the cylindrical structure has a top surface, the groove has a first surface and a second surface, the first surface and the second surface are arranged at an angle, and the intersection position of the first surface and the second surface is lower than the top surface.

[0012] In one embodiment, the first surface is parallel to the top surface, the second surface is located between the first surface and the top surface, and the angle between the second surface and the first surface is 45 degrees to 90 degrees.

[0013] In one embodiment, the guide structure is provided with a rotating shaft, and the distribution structure is sleeved on the rotating shaft, so that the distribution structure is rotatably connected to the guide structure.

[0014] In one embodiment, the guide structure further includes a retaining spring, which is sleeved on the rotating shaft and abuts against the shifting structure to limit the position of the shifting structure on the rotating shaft.

[0015] In one embodiment, the guide structure is a cylindrical structure;

[0016] The lever seat is a cylindrical structure, and the lever is convexly arranged on the cylindrical surface of the lever seat;

[0017] The guide structure and the shift rod seat are coaxially arranged, and / or the guide structure and the shift rod seat have the same diameter.

[0018] In one embodiment, the axial direction of the guide structure is a first direction, a second direction is perpendicular to the first direction, and the second direction is the axial direction of the shifting rod.

[0019] The present invention also proposes a pipe production equipment, which includes an equipment main body and a pipe flanging device as described in any one of the above items, wherein the pipe flanging device is arranged in the downstream direction of the equipment main body.

[0020] The technical solution of the present invention utilizes a guide structure and a distribution structure. The pipe moves along the guide structure until the end of the pipe abuts against the lever located in the distribution structure. Under the obstruction of the lever, the pipe is elastically deformed due to external force, causing the diameter of the self-winding sleeve to gradually increase until it opens, and finally causing the two sides of the pipe to pass through the two sides of the lever. At the same time, the lever limits the movement of the pipe edge with smaller curvature of the self-winding sleeve, causing the pipe edge with larger curvature to be located above the pipe edge with smaller curvature. After the self-winding sleeve is separated from the lever, the elastic deformation is restored, causing the pipe edge with larger curvature to cover the pipe edge with smaller curvature. The pipe edge with larger curvature will cling to the pipe edge with smaller curvature due to its own plasticity, reducing the gap of the self-winding sleeve and improving the protective effect of the self-winding sleeve.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] Combine Figures 1 to 5 The present invention proposes an embodiment, a tube flanging device 100, used to flanging a tube 200, the tube 200 having a first side 201 and a second side 202, the second side 202 covering the first side 201, the tube flanging device 100 includes a guide structure 1 and a distribution structure 2, the distribution structure 2 is connected to one end of the guide structure 1, the distribution structure 2 is provided with a shifting rod 22, the shifting rod 22 and the guide structure 1 are arranged at an angle, wherein the guide structure 1 guides the tube 200 through the distribution structure 2, the shifting rod 22 flips the first side 201 of the tube 200 to the outside of the second side 202, so that the first side 201 covers the second side 202.

[0034] Specifically, the tube 200 is formed by rolling a sheet of material inwardly. For example, the sheet is square and has a first side 201, a second side 202, a third side, and a fourth side. The first side 201 and the second side 202 are opposite each other, and the third side and the fourth side are opposite each other. The first side 201 and the second side 202 are rolled inwardly to form a tube, and the third side and the fourth side form the ends of the tube. The first side 201 and the second side 202 are rolled so that the sheet partially overlaps, and the overlapping portion accounts for approximately 10-90% of the outer diameter of the tube 200. In other words, the first side 201 is rolled inwardly approximately 180 degrees about the axis of the tube 200, so that the second side 202 is outside and the first side 201 is inside, that is, the second side 202 covers the first side 201. The guide structure 1 is connected to the upstream equipment, and the upstream equipment transmits the pipe 200 to the guide structure 1. The guide structure 1 guides the pipe 200 to the distribution structure 2. The distribution structure 2 is provided with a shift rod 22. The axial extension direction of the shift rod 22 is set at an angle to the guiding direction of the guide structure 1. The position of the shift rod 22 blocks the movement path of the pipe 200. During the movement of the pipe 200, the shift rod 22 can abut the overlapping part of the pipe 200.

[0035] Through this embodiment, the tube 200 moves along the guide structure 1 until the end of the tube 200 abuts the lever 22 located on the distribution structure 2. Under the obstruction of the lever 22, the tube 200 is elastically deformed due to external force, causing the diameter of the self-rolling sleeve to gradually increase until it opens, and finally causing the two sides of the tube 200 to pass through the two sides of the lever 22. At the same time, the lever 22 limits the movement of the tube edge with smaller curvature of the self-rolling sleeve, so that the tube edge with larger curvature is located above the tube edge with smaller curvature. After the self-rolling sleeve is separated from the lever 22, the elastic deformation is restored, so that the tube edge with larger curvature covers the tube edge with smaller curvature. The tube edge with larger curvature will be in close contact with the tube edge with smaller curvature due to its own plasticity, reducing the gap of the self-rolling sleeve and improving the protective effect of the self-rolling sleeve.

[0036] Combine Figures 1 to 5 The present invention proposes an embodiment, wherein the shifting structure 2 includes a shifting rod seat 21 and the shifting rod 22, the shifting rod seat 21 being connected to the guide structure 1, the shifting rod 22 being connected to the shifting rod seat 21, and the shifting rod 22 being provided with a first limiting portion 221 and a second limiting portion 222 at intervals along the axial extension direction of the shifting rod 22, the first limiting portion 221 being used to limit the movement position of the first side 201, and the second limiting portion 222 being used to limit the movement position of the second side 202.

[0037] Specifically, the lever seat 21 is connected to one end of the guide structure 1, and the lever seat 21 is provided with a lever 22, which is provided with two limiting parts. When the pipe 200 abuts against the lever 22 but is not shifted by the lever 22, as shown in FIG. Figure 3 As shown, the first edge 201 is located on one side of the lever 22, and the second edge 202 is located on the other side of the lever 22. The first limiting portion 221 is provided at a position of the lever 22 away from the first edge 201, and is used to limit the position of the first edge 201. The second limiting portion 222 is provided at a position of the lever 22 away from the second edge 202, and is used to limit the position of the second edge 202. Along the axial extension direction of the lever 22, the second limiting portion 222 is located lower than the first limiting portion 221, or in other words, the second limiting portion 222 is located closer to the lever seat 21 than the first limiting portion 221. When the tube 200 is separated by the lever 22, that is, when the lever 22 opens the overlapping portion of the tube 200, as shown in FIG. Figure 4 As shown, when the first side 201 and the second side 202 of the tube 200 clamp the shifting rod 22 , the first limiting portion 221 limits the first side 201 , and the second limiting portion 222 limits the second side 202 .

[0038] Through this embodiment, the tube 200, under the guidance of the guide structure 1, abuts the lever 22 of the distribution structure 2, and the tube 200 continues to move, so that the position where the tube 200 abuts the lever 22 undergoes elastic deformation. It can be understood that the lever 22 abuts the overlapping part of the tube 200, and the overlapping part is only plastically overlapped and not fixedly connected. Therefore, the first side 201 and the second side 202 of the tube 200 are separated again under elastic deformation, so that the first side 201 is stuck in the first limiting portion 221, and the second side 202 is stuck in the second limiting portion 222, forming a situation where the first side 201 and the second side 202 clamp the lever 22. The separated tube 200 is not blocked by the shifting rod 22 and can pass through the shifting structure 2. After passing through the shifting structure 2, the first side 201 and the second side 202 are free from the restriction of the shifting rod 22 and the elastic deformation is restored. Since the position of the second limiting portion 222 is lower than the first limiting portion 221, the second side 202 is rolled up first, and then the first side 201 is rolled up, so that the first side 201 covers the second side 202, completing the flanging of the tube 200.

[0039] Combine Figures 1 to 5 The present invention proposes an embodiment, wherein the lever 22 is a cylindrical structure, the first limiting portion 221 is a side surface of the cylindrical structure, and the second limiting portion 222 is a groove located on the other side surface of the cylindrical structure facing away from the first limiting portion.

[0040] Specifically, the first limiting portion 221 is the outer edge of the lever 22, which includes the top surface 201 of the cylindrical surface of the lever 222. The second limiting portion 222 is a groove on the cylindrical surface of the lever 22. The groove is only provided on a portion of the cylindrical surface and does not surround the lever 22. In other words, the groove forms a notch on one side of the lever 22.

[0041] The principle of this embodiment is that the first side 201 and the second side 202 of the pipe are separated and abutted on both sides by abutting the pipe, and the limiting portion is provided to ensure that the heights of the first side 201 and the second side 202 are inconsistent on both sides. It is understood that grooves can be provided on both sides, and the inconsistent position of the grooves can limit the inconsistent position of the first side 201 and the second side 202; or the groove can be provided on only one side, and the other side is a smooth cylindrical side, so that one side is confined within the groove and the other side extends along the cylindrical side to the highest point, so that it is higher than the groove, which can also achieve the same effect.

[0042] Optionally, the structure of the shift lever is not limited to a cylindrical structure, but may be a prismatic structure.

[0043] In this embodiment, the first side 201 and second side 202 of the tube 200 re-separate under elastic deformation. The first side 201 abuts the outer edge of the lever 22, while the second side 202 initially abuts the outer edge of the lever 22. When the second side 202 abuts the outer edge of the lever 22, it abuts the groove, where it is guided by the groove and abuts the groove wall. Because the groove is lower than the top surface 2211 of the lever 22, meaning the second side 202 is closer to the lever seat 21, the second side 202 recovers its elastic deformation first, followed by the first side 201, so that the first side 201 covers the second side 202.

[0044] Combine Figures 1 to 5 The present invention proposes an embodiment, wherein the groove has a first surface 2221 and a second surface 2222, the first surface 2221 and the second surface 2222 are set at an angle, and the intersection position of the first surface 2221 and the second surface 2222 is lower than the top surface 2211.

[0045] Specifically, the groove has two intersecting surfaces, the first surface 2221 is used to limit the height of the second side 202 , and the second surface 2222 is used to guide the sliding direction and position of the second side 202 .

[0046] In this embodiment, the second side 202, under the contact of the lever 22, enters the second surface 2222. The second surface 2222 guides the second side 202 to slide onto the first surface 2221, specifically at the intersection of the first surface 2221 and the second surface 2222. This intersection is lower than the top surface 2211 of the lever 22, i.e., the position where the lever 22 restrains the second side 202 is lower than the position of the first side 201. Therefore, after the first side 201 and the second side 202 are freed from the restraint of the lever 22 and elastically recover, the first side 201 covers the second side 202.

[0047] Combine Figures 1 to 5 The present invention proposes an embodiment in which the second surface 2222 is located between the first surface 2221 and the top surface 2211 , and the angle between the second surface 2222 and the first surface 2221 is 45 degrees to 90 degrees.

[0048] Specifically, the first surface 2221 is located near the lever seat 21 and / or the guide structure 1. As can be understood, when the tube 200 is moved around the guide structure 1, the proximity of the first surface 2221 to the guide structure 1 allows the second side 202 to recover its elastic deformation earlier, thereby increasing the rate at which the first side 201 covers the second side 202. The second surface 2222 and the first surface 2221 form an angle of 45 to 90 degrees, which provides space for the second side 202 to recover its elastic deformation.

[0049] Through this embodiment, when the lever 22 separates the first side 201 and the second side 202, the intersection position of the first surface 2221 and the second surface 2222 of the second limiting portion 222 and the space formed enable the second side 202 to complete partial recovery of elastic deformation when abutting the lever 22, while the first side 201 is still abutted by the lever 22 and produces elastic deformation, thereby improving the success rate and speed of the first side 201 covering the second side 202 after the tube 200 passes through the distribution structure 2.

[0050] Combine Figures 1 to 5 The present invention proposes an embodiment in which the guide structure 1 is provided with a rotating shaft 11 , and the distribution structure 2 is sleeved on the rotating shaft 11 so that the distribution structure 2 is rotatably connected to the guide structure 1 .

[0051] Specifically, a rotating shaft 11 is protruded from one end of the guide structure 1 , the shifting structure 2 is sleeved on the rotating shaft 11 , and the shifting rod 22 can rotate around the axis of the rotating shaft 11 , which is also the axis of the guide structure 1 .

[0052] Furthermore, the shifting structure 2 is provided with a bearing or a damping connector, which is connected to the rotating shaft 11 through the bearing or the damping connector, so that the shifting rod 22 can be freely rotated to adjust the position, or the position of the shifting rod 22 can be manually controlled.

[0053] According to this embodiment, the tube 200 may produce circumferential deformation during thermoplasticization, so that the overlapping positions of the tubes 200 are not always located in one direction, that is, they may be located at different radial positions of the guide structure 1. By providing a rotatable lever 22, the lever 22 can be simultaneously clamped by the first side 201 and the second side 202 of the tube 200 to adjust the position of the lever 22, thereby better performing the distribution and avoiding the lever 22 contacting the tube 200 at an incorrect position, thereby destroying the shaping of the tube 200 and affecting the shape and structure of the tube 200.

[0054] Combine Figures 1 to 5 The present invention proposes an embodiment, wherein the guide structure 1 further includes a retaining spring 12 , which is sleeved on the rotating shaft 11 and abuts against the distribution structure 2 to limit the position of the distribution structure 2 on the rotating shaft 11 .

[0055] Specifically, two grooves for installing the clamping springs 12 are provided on the rotating shaft 11 , and the two clamping springs 12 are sleeved in the grooves to clamp the distribution structure 2 .

[0056] According to this embodiment, the clamping spring 12 can not only limit the position of the distribution structure 2 but also facilitate the disassembly or replacement of the distribution structure 2 .

[0057] Combine Figures 1 to 5 , the present invention proposes an embodiment, wherein the guide structure 1 is a cylindrical structure;

[0058] The lever seat 21 is a cylindrical structure, and the lever 22 is protruding from the cylindrical surface of the lever seat 21;

[0059] The guide structure 1 and the shift rod seat 21 are coaxially arranged.

[0060] Specifically, the guide structure 1 is cylindrical, the rotating shaft 11 is cylindrical, and the lever seat 21 is cylindrical. The guide structure 1, rotating shaft 11, and lever seat 21 are all coaxially arranged. As will be understood, when the tube 200 is sleeved on the guide structure 1 and moves along the axis of the guide structure 21, the tube 200 will also be sleeved on the lever seat 21 and then leave the tube flanging device 100. The outer diameter of the guide structure 1 is equal to or smaller than the inner diameter of the tube 200. The lever 22 is disposed on the circumferential surface of the lever seat 21.

[0061] Through this embodiment, the cylindrical guide structure 1 and the shifting rod seat 21 make it easier for the pipe 200 to move on the guide structure 1 and the shifting structure 2 .

[0062] Combine Figures 1 to 5 The present invention proposes an embodiment in which the axial direction of the guide structure 1 is a first direction, and a second direction is perpendicular to the first direction, and the second direction is the axial direction of the shift rod 22 .

[0063] Specifically, the axial extension direction of the shift rod 22 is the radial direction of the shift rod seat 21 .

[0064] Through this embodiment, the shifting rod 22 can be accurately located in the radial position of the tube 200, better applying force to the overlapping part of the tube 200, so that the first side 201 and the second side 202 of the tube 200 are relatively evenly stressed, and the shifting effect is better.

[0065] The present invention also provides a pipe 200 production device, comprising a device body and any of the aforementioned pipe flanging devices 100. The specific structure of the pipe flanging device 100 is similar to the aforementioned embodiments. Since the present pipe flanging device 100 utilizes all of the technical solutions of all of the aforementioned embodiments, it at least possesses all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be described in detail here. The device body produces a pipe 200 having a first side 201 and a second side 202, with the second side 202 enclosing the first side 201. The pipe flanging device 100 is located downstream of the device body and guides the pipe 200 through the lever 22 structure so that the first side 201 of the pipe 200 encloses the second side 202.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
