AI Technical Summary
In the existing technology, the vertical baffle on the saw is difficult to effectively fix the standard elbow pipe, resulting in large angle errors when cutting non-standard elbow pipes, which increases the difficulty and cost of repair. Furthermore, it is difficult to align with the CNC beveling machine during subsequent beveling, affecting the processing accuracy and efficiency.
The design employs a combination structure of a support tube and a positioning ring plate. The support tube contains positioning holes and clearance holes. The positioning ring plate is fixed to one end of the support tube. The positioning holes are used to accommodate the elbow tube, and the clearance holes are used for clearance, ensuring stable positioning of the elbow tube end and preventing warping. During cutting, the elbow tube is accurately cut along the cutting line, and during beveling, it is aligned with the CNC beveling machine tool to ensure cutting accuracy and prevent the elbow tube from being cut at the point of obstruction. This also prevents warping and ensures accurate cutting along the cutting line, and alignment with the CNC beveling machine tool during beveling.
The combination of support tube and positioning ring plate achieves stable positioning of elbow tube, improves cutting accuracy and beveling accuracy, reduces repair costs and processing time, ensures that the end of elbow tube is aligned with the tool, and improves processing efficiency.

[0003] When cutting the elbow pipe, the cutting line is usually marked on the standard elbow pipe according to the corner angle of the non-standard elbow pipe, then the vertical stop plate on the sawing machine is clamped on both sides of the pipe body of the standard elbow pipe, and the cutting line is exposed outside the vertical stop plate, and finally the cutting knife on the sawing machine is driven to move from top to bottom to cut the cutting line part of the standard elbow pipe.
[0004] However, due to the large size of the elbow pipe, the vertical stop plate on the sawing machine cannot effectively fix the standard elbow pipe, and the end of the elbow pipe on the sawing machine is easy to lift, resulting in a large angle error of the non-standard elbow pipe after cutting. The large angle error of the non-standard elbow pipe not only increases the processing cost and delays the construction period due to the difficulty of repair, but also makes it difficult to center the port of the non-standard elbow pipe with the bevel processing tool on the numerical control bevel machine during subsequent beveling operation, further causing processing failure and increasing processing cost.

[0006] In the first aspect, the utility model provides a supporting device for elbow pipe processing, which comprises a supporting pipe;
[0007] At least one end of the supporting pipe is fixed with a positioning ring plate, the inner circle of the positioning ring plate forms a positioning hole, and the diameter of the positioning hole is equal to the outer diameter of the elbow pipe to be processed; the supporting pipe is used to accommodate the elbow pipe to be processed, and the positioning hole is used to pass through one end of the elbow pipe to be processed and make the end face of the end of the elbow pipe to be processed located in the vertical plane;
[0008] The tube body of the support tube is provided with a clearance hole for providing clearance for the end of the elbow pipe to be processed away from the positioning hole, so that the end of the elbow pipe to be processed can extend out of the support tube.
[0009] In an optional embodiment, the positioning ring plate is detachably connected with the support tube.
[0010] In an optional embodiment, the positioning ring plate is a plurality of positioning ring plates, the positioning holes on the plurality of positioning ring plates are not all of the same diameter, and the plurality of positioning ring plates are selectively connected with the support tube.
[0011] In an optional embodiment, the tube body of the support tube is provided with an ear.
[0012] In an optional embodiment, the ear and the clearance hole are located on the same side of the support tube.
[0013] In an optional embodiment, the ear is two ears, the two ears are distributed along the axial direction of the support tube, and one of the two ears is fixed between one end of the support tube and the clearance hole, and the other ear is fixed between the other end of the support tube and the clearance hole.
[0014] In an optional embodiment, the side of the clearance hole away from the positioning hole has a gap with the outer wall of the elbow pipe to be processed.
[0015] In an optional embodiment, any side of the clearance hole has a gap with the outer wall of the elbow pipe to be processed.
[0016] In an optional embodiment, the clearance hole is a strip-shaped hole and the clearance hole extends along the axial direction of the support tube.
[0017] In an optional embodiment, the shape of the support tube is cylindrical.
[0018] The utility model provides a support device for elbow pipe machining, which comprises a support pipe. At least one end of the support pipe is fixed with a positioning ring plate. An inner ring of the positioning ring plate forms a positioning hole. A diameter of the positioning hole is equal to an outer diameter of an elbow pipe to be machined. The support pipe is used to accommodate the elbow pipe to be machined. The positioning hole is used to allow one end of the elbow pipe to be machined to pass through and make an end face of the end of the elbow pipe to be machined located on a vertical plane. A pipe body of the support pipe is provided with a clearance hole. The clearance hole is used to make room for an end portion of the elbow pipe to be machined away from the positioning hole, so that the end portion of the elbow pipe to be machined can extend out of the support pipe. The support device for elbow pipe machining is used for cutting and beveling of a non-standard elbow pipe. During the machining process, a standard elbow pipe (i.e., an elbow pipe with a corner angle of 90 degrees) can be selected according to the size of the non-standard elbow pipe. At this time, the standard elbow pipe is the elbow pipe to be machined. Then, the standard elbow pipe can be placed in the support pipe through the clearance hole, and one end of the standard elbow pipe can extend out of the support pipe after passing through the positioning hole on the positioning ring plate. Then, a cutting line can be marked on the standard elbow pipe exposed outside the support pipe according to the corner angle of the non-standard elbow pipe, so as to ensure that the cutting line and the part to be cut and discarded of the standard elbow pipe are located outside the support pipe. If the distance between the end portion of the standard elbow pipe away from the positioning hole and the corner thereof is large at this time, the end portion of the standard elbow pipe away from the positioning hole can be exposed outside the support pipe through the clearance hole, so as to prevent the support pipe from hindering the standard elbow pipe. After the standard elbow pipe is placed in the support pipe, the support pipe with the standard elbow pipe is placed horizontally on a sawing bed for cutting. Then, the support pipe is clamped by the vertical stop plates on the sawing bed. Since the standard elbow pipe is supported and limited by the positioning hole at this time, the central axis of the end portion of the standard elbow pipe located outside the support pipe can be stably located on a horizontal plane. Correspondingly, the end face of the standard elbow pipe located outside the support pipe is located on a vertical plane. Thus, under the limiting action of the positioning hole, the end portion of the standard elbow pipe located outside the support pipe will not be tilted due to the large size of the elbow pipe. When the cutting knife on the sawing bed moves from top to bottom and cuts the standard elbow pipe, the part to be cut and discarded of the standard elbow pipe can be accurately cut along the cutting line, so as to effectively ensure the cutting accuracy and reduce the difficulty of repair, and even no repair is needed. At this time, the machining period can also be effectively guaranteed. After cutting is completed, the cut elbow pipe and the support pipe can be transferred to a numerical control beveling machine at the same time. At this time, the support pipe placed horizontally on the machine can also be clamped by the clamping device on the numerical control beveling machine, so as to ensure that the end face of the cut end portion of the elbow pipe is located on a vertical plane. Then, the position of the elbow pipe can be adjusted, so that the cut end portion of the elbow pipe is centered with the beveling tool on the numerical control beveling machine. Since the end face of the cut end portion of the elbow pipe is located on a vertical plane at this time, the end portion is easily centered with the beveling tool whose central axis is also located on a horizontal plane, so as to effectively ensure the beveling accuracy and reduce the machining failure and cost.
[0019] Compared with the prior art, the supporting device provided by the utility model can stably support the elbow pipe to be processed through the positioning ring plate on the supporting pipe, prevent the end part close to the cutting part of the elbow pipe to be processed from being raised to affect the cutting precision, thereby effectively improving the processing precision, reducing the repair cost and processing time, and ensuring the smooth centering of the elbow pipe and the cutter in the subsequent groove processing process.

[0028] In order to make the purpose, technical scheme and advantages of the utility model embodiments more clear, the following will combine the drawings in the utility model embodiments to clearly and completely describe the technical scheme in the utility model embodiments, obviously, the described embodiments are some embodiments of the utility model, not all the embodiments. The components of the utility model embodiments described and shown in the drawings here can be arranged and designed in various different configurations.
[0029] Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the application.
[0030] Some embodiments of the application will be described in detail below with reference to the drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.
[0031] Embodiments:
[0032] As shown in Figure 1 , Figure 2 and Figure 3 , the support device for elbow pipe machining provided in the embodiment includes a support pipe 1; at least one end of the support pipe 1 is fixed with a positioning ring plate 2, the inner circle of the positioning ring plate 2 forms a positioning hole 20, the diameter of the positioning hole 20 is equal to the outer diameter of the elbow pipe to be machined; the support pipe 1 is used to accommodate the elbow pipe to be machined, the positioning hole 20 is used to pass one end of the elbow pipe to be machined and make the end face of the end of the elbow pipe to be machined located in a vertical plane; the pipe body of the support pipe 1 is provided with a clearance hole 10, the clearance hole 10 is used to provide clearance for the end of the elbow pipe to be machined away from the positioning hole 20, so that the end of the elbow pipe to be machined can extend out of the support pipe 1.
[0033] The support device for elbow pipe machining provided in the embodiment is used in the cutting and beveling process of a non-standard elbow pipe 4, the non-standard elbow pipe 4 is an elbow pipe with a corner angle other than 90 degrees, for example, an elbow pipe with a corner angle of 73 degrees, as shown in Figure 5 and Figure 6 .
[0034] In the machining process, a standard elbow pipe 3 (i.e. an elbow pipe with a corner angle of 90 degrees) can be selected according to the size of the non-standard elbow pipe 4 as shown in Figure 5 , the structure of the standard elbow pipe 3 is as shown in Figure 4 , at this time the standard elbow pipe 3 is the elbow pipe to be machined as described above. Then the standard elbow pipe 3 can be placed in the support pipe 1 through the clearance hole 10, at the same time one end of the standard elbow pipe 3 is made to extend out of the support pipe 1 after passing through the positioning hole 20 on the positioning ring plate 2, and then a cutting line is marked on the standard elbow pipe 3 exposed outside the support pipe 1 according to the corner angle of the non-standard elbow pipe 4, so as to ensure that the cutting line and the part to be cut off of the standard elbow pipe 3 are both located outside the support pipe 1.
[0035] As shown in Figure 2 and Figure 3As shown, if the distance between the end of the standard elbow pipe 3 away from the positioning hole 20 and the corner thereof is large at this time, the diameter of the support pipe 1 is small, and the space in the pipe cannot accommodate the end of the standard elbow pipe 3 away from the positioning hole 20, the end of the standard elbow pipe 3 away from the positioning hole 20 can also be exposed outside the support pipe 1 by using the accommodation hole 10, thereby preventing the support pipe 1 from hindering the placement of the standard elbow pipe 3.
[0036] After the standard elbow pipe 3 is placed in the support pipe 1, the support pipe 1 with the standard elbow pipe 3 is placed horizontally on a sawing bed for cutting, and the support pipe 1 is clamped by the vertical clamping plates on the sawing bed. At this time, the standard elbow pipe 3 is supported and limited by the positioning hole 20, so the central axis of the end of the standard elbow pipe 3 outside the support pipe 1 can be stably positioned on the horizontal plane, and correspondingly, the end surface of the standard elbow pipe 3 outside the support pipe 1 is located on the vertical plane. Thus, under the limiting action of the positioning hole 20, the end of the standard elbow pipe 3 outside the support pipe 1 will not be tilted due to the large size of the elbow pipe, and when the cutting knife on the sawing bed moves from top to bottom and cuts the standard elbow pipe 3, the standard elbow pipe 3 can be accurately cut along the cutting line, thereby effectively ensuring the cutting accuracy, reducing the repair difficulty, and even eliminating the need for repair, and the processing period can also be effectively guaranteed.
[0037] After cutting, a non-standard elbow pipe 4 as shown in Figure 5 can be obtained. At this time, the non-standard elbow pipe 4 needs to be subjected to a beveling operation. In the beveling process, the cut elbow pipe and the support pipe 1 are transferred to a numerical control beveling machine at the same time. At this time, the support pipe 1 placed horizontally on the machine can also be clamped by the clamping device on the numerical control beveling machine, thereby ensuring that the end surface of the cut elbow pipe is located on the vertical plane. Then, the position of the elbow pipe can be adjusted so that the cut end of the elbow pipe is centered with the beveling tool on the numerical control beveling machine. Since the end surface of the cut elbow pipe is located on the vertical plane at this time, the end of the elbow pipe is easily centered with the beveling tool whose central axis is also located on the horizontal plane, thereby effectively ensuring the beveling accuracy, effectively reducing the processing failure, and improving the processing efficiency. The non-standard elbow pipe 4 after beveling is as shown in Figure 6 . Since the numerical control beveling machine and the beveling tool are prior art, their specific structures and working processes are not described here.
[0038] Compared with the prior art, the support device provided by the embodiment can stably support the elbow pipe to be processed by the positioning ring plate 2 on the support pipe 1, prevent the end of the elbow pipe to be processed near the cutting position from being tilted to affect the cutting accuracy, thereby effectively improving the processing accuracy, reducing the repair cost and processing time, and ensuring the smooth centering of the elbow pipe with the tool in the subsequent beveling process.
[0039] It should be noted that one end of the support pipe 1 is fixed with the positioning ring plate 2, which can meet the bending pipe machining requirement, but in order to improve the fitting range of the elbow pipe machining support device, the two ends of the support pipe 1 can be respectively fixed with the positioning ring plate 2, and the diameters of the two positioning ring plates 2 can be different, at this time, the two positioning ring plates 2 can adapt to two different diameter bending pipes, and realize the machining process of two different diameter non-standard bending pipes.
[0040] In addition, the positioning ring plate 2 and the support pipe 1 in the embodiment can be fixedly connected by welding or the like, or can be detachably connected. The detachable connection mode is, for example, threaded connection, clamping or connection through screws and the like fasteners.
[0041] In order to facilitate the machining of bending pipes of different sizes, the positioning ring plate 2 and the support pipe 1 are preferably detachably connected.
[0042] Further, the positioning ring plate 2 can be multiple, and the diameters of the positioning holes 20 on the multiple positioning ring plates 2 are all different, and the multiple positioning ring plates 2 are selectively connected with the support pipe 1.
[0043] The multiple positioning ring plates 2 are used to adapt to bending pipes of different sizes, when it is needed to machine bending pipes of different sizes, only the corresponding positioning ring plate 2 is selected according to the diameter of the bending pipe, and then the selected positioning ring plate 2 is fixed at the end of the support pipe 1.
[0044] As shown in Figures 1-3 , the support pipe 1 is provided with a lifting lug 11 on the pipe body.
[0045] The lifting lug 11 facilitates the connection of the hoisting device such as the hand-operated hoist with the support pipe 1, thereby facilitating the overall hoisting of the elbow pipe machining support device provided with the standard elbow pipe 3 to the sawing machine or numerical control beveling machine, effectively improving the use convenience of the elbow pipe machining support device.
[0046] In the embodiment, the positioning ring plate 2 can be cut from a steel plate, and the support pipe 1 can be formed by a pipe, and correspondingly, the lifting lug 11 can also be cut from a steel plate. At this time, the positioning ring plate 2, the support pipe 1 and the lifting lug 11 are all manufactured from materials that are easy to obtain in construction, or even the positioning ring plate 2, the support pipe 1 and the lifting lug 11 can be processed from the excess materials or waste materials in construction, effectively reducing the manufacturing cost of the elbow pipe machining support device.
[0047] Further, as shown in Figures 1-2 , the lifting lug 11 and the relief hole 10 are arranged on the same side of the support pipe 1.
[0048] When the lug 11 and the clearance hole 10 are arranged on the same side of the support pipe 1, the part of the standard elbow pipe 3 extending out of the support pipe 1 through the clearance hole 10 can be located above the support pipe 1 during hoisting, thereby facilitating smooth hoisting. Therefore, the lug 11 and the clearance hole 10 are preferably arranged on the same side of the support pipe 1.
[0049] In addition, as shown in Figures 1-3 , the lug 11 can be two, and the two lugs 11 are spaced along the axial direction of the support pipe 1, and one of the lugs 11 is fixed between one end of the support pipe 1 and the clearance hole 10, and the other lug 11 is fixed between the other end of the support pipe 1 and the clearance hole 10. This arrangement makes the distribution of the lug 11 on the support pipe 1 more balanced, thereby making the hoisting process more stable.
[0050] As shown in Figure 2 and Figure 3 , the side of the clearance hole 10 away from the positioning hole 20 has a gap with the outer wall of the elbow pipe to be processed. The gap makes the length of the clearance hole 10 greater than the cross-sectional length of the elbow pipe to be processed (i.e., a non-standard elbow pipe) at the clearance hole 10, thereby making the clearance hole 10 adaptable to more sizes of the elbow pipe to be processed, facilitating the improvement of the application range of the support device for elbow pipe processing.
[0051] Further, any side of the clearance hole 10 can have a gap with the outer wall of the elbow pipe to be processed. The gap can further enlarge the size of the clearance hole 10, not only improving the installation convenience of the elbow pipe to be processed on the support pipe 1, but also further improving the application range of the clearance hole 10 to different sizes of the elbow pipe to be processed.
[0052] The shape of the clearance hole 10 is not limited, since the strip-shaped hole can not only meet the requirement that the size of the clearance hole 10 is greater than the size of the elbow pipe to be processed, but also has a smaller opening area compared with a round hole. Therefore, the clearance hole 10 is preferably a strip-shaped hole and extends along the axial direction of the support pipe 1.
[0053] Further, the clearance hole 10 can be a waist-shaped hole.
[0054] In actual application, the support pipe 1 can adopt a cuboid shape, a prism shape, or a cylindrical shape. Since the support pipe 1 is cylindrical, it is easier to carry and the cylindrical pipe is easier to obtain. Therefore, as shown in Figures 1-2 , the shape of the support pipe 1 is preferably cylindrical.
[0055] In summary, the support device for elbow pipe machining provided by the embodiment is convenient to obtain and regular in shape, and is easy to process, when the non-standard elbow pipe 4 is machined, the positioning ring plate 2 can limit and support the non-standard elbow pipe 4, so that only one worker can complete the cutting operation by using a sawing machine, which can not only improve the machining precision and reduce the artificial repair polishing amount, but also effectively reduce the personnel investment and save the labor cost.
[0056] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
