Description

Technical Field

[0001] The present invention relates to the technical field of elbow processing, and specifically to a butt-welding elbow processing equipment and process. Background Art

[0002] The manufacturing process of butt-welding elbows includes using medium plates as raw materials, cutting them and then pressing them into half of the profiles of two elbows, and then butt-jointing and welding. This manufacturing method usually results in two weld seams for butt-welding elbows, which is suitable for large-diameter and high-batch production. However, during the pressing process of large butt-welding elbow pieces, due to the limitations of the weight and volume of the molds used, existing equipment such as overhead cranes and forklifts cannot meet the requirements for installing the upper and lower tire molds and loading the butt-welding elbow pieces. Summary of the Invention

[0003] The purpose of the present invention is to provide a butt-welding elbow processing equipment and process to solve the problems raised in the above background art.

[0004] To achieve the above invention purpose, the present invention adopts the following technical solutions:

[0005] A butt-welding elbow processing equipment provided by the present invention includes a four-column hydraulic press, a processing mold and a control center. The processing mold includes a female mold and a male mold. It is characterized in that it further includes a feeding installation platform;

[0006] The four-column hydraulic press includes a base, a lower mold base, an upper mold base and a driving mechanism. The lower mold base is fixedly installed at the top of the base, and at the four corner positions of the top of the lower mold base, guide columns are vertically and fixedly arranged. The upper mold base is slidably assembled between the four guide columns and can only slide axially along the guide columns. The driving mechanism is installed at the top of the four guide columns, and the driving mechanism is connected to the upper mold base and can drive the upper mold base to slide on the guide columns;

[0007] The male mold is detachably installed at the bottom of the upper mold base; T-shaped clamping grooves are uniformly arranged at the bottom of the upper mold base, and a clamping component adapted to the T-shaped clamping grooves is detachably installed at the top of the male mold;

[0008] The feeding installation platform is arranged on one side of the lower mold base. The feeding installation platform includes a positioning seat, a feeding installation plate slidably installed on the top of the positioning seat, and a hydraulic telescopic cylinder for driving the feeding installation plate to slide into or out of the upper part of the lower mold base in a side-sliding manner. The female mold is detachably installed at the top of the feeding installation plate, and the T-shaped clamping grooves are arranged along the sliding direction of the feeding installation plate.

[0009] Further, a mold cavity is formed at the top of the female mold, and the longitudinal section of the mold cavity is semicircular, and the overall shape of the mold cavity is bent tubular, and the male mold is adapted to the mold cavity.

[0010] Further, bolt holes are evenly distributed on the loading mounting plate, and a mounting seat is arranged at the bottom of the female die. The mounting seat can be bolted to the bolt holes of the loading mounting plate, so that the female die is fixed on the top of the loading mounting plate.

[0011] Further, the clamping component includes a movable clamping plate, a mounting substrate, and a connection structure arranged between the movable clamping plate and the mounting substrate. There is a movable gap between the movable clamping plate and the mounting substrate, and a T-shaped clamping bar corresponding to the T-shaped clamping groove is arranged at the top of the movable clamping plate;

[0012] A strip-shaped connection groove is penetrated and opened at the central position of the mounting substrate. The strip-shaped connection groove includes an upper groove body and a lower groove body, and the longitudinal section of the upper groove body is smaller than that of the lower groove body;

[0013] The connection structure includes a connection column vertically fixed at the bottom of the movable clamping plate. The connection column penetrates through the upper groove body and is fixedly connected with a limit disk. The diameter of the connection column is equal to the width of the upper groove body, and the diameter of the limit disk is equal to the width of the lower groove body. Handles are symmetrically arranged on both sides of the movable clamping plate.

[0014] Further, the clamping component further includes a correction component arranged between the movable clamping plate and the mounting substrate. The correction component includes correction columns arranged in a rectangular array and fixed at the bottom of the movable clamping plate. A rolling ball is embedded at the bottom of the correction column. A conical groove is opened at the top of the mounting substrate corresponding to the position of the correction column. When the bottom surface of the movable clamping plate is attached to the top surface of the mounting substrate, the rolling ball of the correction column abuts against the central position at the bottom of the conical groove.

[0015] Further, the clamping component further includes a positioning plugging plate arranged between the movable clamping plate and the mounting substrate. The positioning plugging plate includes plugging parts symmetrically arranged on both sides of the connection column and a connection part connected to one end of a pair of plugging parts. Among them, a plugging groove adapted to the plugging parts is formed between the movable clamping plate and the mounting substrate. The plugging groove includes a first groove body arranged on the bottom surface of the movable clamping plate and a second groove body arranged on the top surface of the mounting substrate.

[0016] Further, the loading mounting plate includes a lower bottom plate, an upper bottom plate, and a lifting component. The lower bottom plate is slidably assembled on the positioning seat, and the upper bottom plate is installed on the top of the lower bottom plate through a lifting structure.

[0017] Further, the lifting assembly includes four first telescopic structures disposed between the lower bottom plate and the upper bottom plate, and a second telescopic structure fixedly installed at one end of the lower bottom plate close to the hydraulic telescopic cylinder. The first telescopic structure includes a cylinder body, a piston movably disposed inside the cylinder body, and a first movable rod vertically fixed to the top of the piston and fixedly connected to the upper bottom plate. The second telescopic structure includes a box body fixedly connected to the lower bottom plate, a movable plate horizontally slidably disposed inside the box body, and a second movable rod fixed to one side of the movable plate and fixedly connected to the output end of the hydraulic telescopic cylinder. Wherein, the inside of the box body is communicated with the inside of the four cylinder bodies through pipelines; a contact plate is installed at the bottom of the lower die base.

[0018] The present invention also provides a process using the above butt welding elbow processing equipment, including the following steps:

[0019] Step 1: Select a suitable processing die according to requirements, and install the clamping assembly on the top of the corresponding convex die.

[0020] Step 2: Use a traveling crane or a forklift to transfer the selected processing die to the top of the loading and installation plate. During this process, adjust the angle of the processing die so that the T-shaped clamping strip of the clamping assembly is parallel to the sliding direction of the loading and installation plate.

[0021] Step 3: Drive the upper die base to move through the driving mechanism so that the bottom surface of the upper die base and the top surface of the clamping assembly are at the same height.

[0022] Step 4: Move the positioning insertion plate of the clamping assembly out from between the movable clamping plate and the installation substrate, adjust the movable clamping plate so that its T-shaped clamping strip corresponds to the T-shaped clamping groove, and then start the hydraulic telescopic cylinder to drive the loading and installation plate to slide above the lower die base. During this process, when the loading and installation plate contacts the contact plate, the hydraulic oil in the box body is introduced into the cylinder body to move the upper bottom plate upward. Under the action of the correction component, the installation substrate and the convex die are reset and aligned with the positioning insertion plate.

[0023] Step 5: Drive the loading and installation plate to reset through the hydraulic telescopic cylinder, and then insert the positioning insertion plate between the movable clamping plate and the installation substrate to limit the movable clamping plate and the installation substrate, completing the installation of the upper die.

[0024] Step 6: Place the processing plate on the female die, drive the loading and installation plate to drive the female die to move below the convex die through the hydraulic telescopic cylinder, and then drive the lower die base to move downward through the control center so that the female die and the convex die are closed, so that the plate between the female die and the convex die forms an elbow split under the action of high pressure.

[0025] Step 7: Butt the two elbow splits and weld along the gap between them to obtain a butt welding elbow.

[0026] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0027] 1. The present invention can select processing molds of different specifications according to the elbow dimensions required by actual requirements, install the corresponding punch on the upper die base, and realize the continuous production of elbows.

[0028] 2. When the punch needs to be installed in the present invention, the punch can be transferred to the loading and installation plate by equipment such as a crane and a forklift. Subsequently, after adjusting the position of the punch, the loading and installation plate is driven by a hydraulic telescopic cylinder to slide above the lower die base. During this process, the clamping component is smoothly clamped into the upper die base to complete the installation of the punch.

[0029] During the processing, the female die can be fixed on the loading and installation plate. Subsequently, during the process of the loading and installation plate moving back and forth between the lower die base and the positioning seat, the elbow split parts are continuously taken out from the female die, and the plates to be processed are placed on the female die by equipment such as a crane and a forklift, so as to continuously complete the manufacturing work of the elbow split parts.

[0030] 3. Compared with the conventional technology, the present invention needs to adjust the position and angle of the punch to achieve the precise docking of the clamping component with the T-shaped clamping groove of the lower die base. In this device, it only needs to roughly correspond the clamping component of the punch with the T-shaped clamping groove of the upper die base during the process of the crane transferring the punch to the loading and installation plate. Subsequently, the precise docking of the clamping component with the T-shaped clamping groove of the lower die base is achieved by adjusting the position and angle of the movable clamping plate, which greatly reduces the labor intensity of the operator and improves the installation efficiency of the punch.

[0031] 4. When the punch moves to a suitable position in the present invention, after the installation substrate and the punch are corrected by the correction component, through the movable clamping plate, it is ensured that the installation substrate and the movable clamping plate remain relatively stationary after installation, so as to ensure that the punch and the female die can be normally closed.

Detailed implementation manner

[0054] In order to enable those skilled in the art of this technology to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0055] Please refer to Figures 1 - 18 , the present invention provides a butt-welding elbow processing device, including a four-column hydraulic press 1, a processing die 2 and a control center 3. The processing die 2 includes a female die 21 and a male die 22 (as Figure 5 shown);

[0056] When in use, the control center 3 can control the operation of the four-column hydraulic press 1, and the four-column hydraulic press 1 provides pressure to make the female die 21 and the male die 22 complete the die closing, so that the plate between the female die 21 and the male die 22 forms an elbow split body 6 under the action of high pressure (as Figure 6 shown).

[0057] Among them, as Figure 1As shown, the four-column hydraulic press 1 includes a base 11, a lower die holder 12, an upper die holder 13 and a driving mechanism 14. The lower die holder 12 is fixedly installed at the top of the base 11, and four guide columns 15 are vertically and fixedly arranged at the four corner positions of the top of the lower die holder 12. The upper die holder 13 is slidably assembled between the four guide columns 15 and can only slide axially along the guide columns 15. The driving mechanism 14 is installed at the top ends of the four guide columns 15, and the driving mechanism 14 is connected to the upper die holder 13 and can drive the upper die holder 13 to slide on the guide columns 15.

[0058] During use, the processing die 2 can be placed between the upper die holder 13 and the lower die holder 12. The driving mechanism 14 provides a driving force to move the upper die holder 13 downward, so that the sheet between the concave die 21 and the convex die 22 is forged into the elbow split body 6 through their cooperation.

[0059] In order to continuously complete the manufacturing work of elbow split bodies 6 of different sizes, the convex die 22 is detachably installed at the bottom of the upper die holder 13; T-shaped clamping grooves 131 are uniformly arranged at the bottom of the upper die holder 13, and a clamping component 4 adapted to the T-shaped clamping grooves 131 is detachably installed at the top of the convex die 22.

[0060] Based on the above design, the operator can select processing dies 2 of different specifications according to actual requirements (i.e., the required elbow size), and install the corresponding convex die 22 on the upper die holder 13 through the clamping component 4 to achieve continuous production of the elbow split body 6;

[0061] Specifically, the clamping component 4 is installed at the top of the corresponding convex die 22, so that the convex die 22 can be fixed on the upper die holder 13 through the clamping component 4 (as Figure 4 shown); during processing, the upper die holder 13 can drive the convex die 22 to move together under the control of the control center 3, so that the convex die 22 reciprocates up and down continuously to cooperate with the concave die 21 to continuously complete the manufacturing work of the elbow split body 6.

[0062] Due to the relatively large weight of the processing die 2, the transfer of the processing die 2 is generally completed by using equipment such as overhead cranes and forklifts in conventional technologies. However, due to the obstruction of the upper die base 13 and the driving mechanism 14, it is not convenient to transfer the processing die 2 between the upper die base 13 and the lower die base 12 by using equipment such as overhead cranes and forklifts. Therefore, in this embodiment, the butt-welding elbow processing equipment further includes a feeding installation platform 5. The feeding installation platform 5 is arranged on one side of the lower die base 12. The feeding installation platform 5 includes a positioning seat 51, a feeding installation plate 52 slidably installed on the top of the positioning seat 51, and a hydraulic telescopic cylinder 53 for driving the feeding installation plate 52 to slide into or out of the upper part of the lower die base 12 in a side-sliding manner. The female die 21 is detachably installed on the top of the feeding installation plate 52, and the T-shaped clamping groove 131 is arranged along the sliding direction of the feeding installation plate 52.

[0063] Based on the above setting of the feeding installation platform, it not only facilitates the installation work of the punch, but also facilitates the unloading and feeding work.

[0064] Specifically, when the operator determines the specifications of the processing die 2, first, the installation work of the punch 22 needs to be completed. In this process, the operator first installs the clamping component 4 on the top of the punch 22, and then transfers the processing die 2 to the feeding installation plate 52 by using equipment such as overhead cranes and forklifts. Then, the position of the clamping component 4 is adjusted (i.e., making the clamping component 4 correspond to the T-shaped clamping groove 131 of the upper die base 13), and the upper die base 13 is lowered to correspond to the clamping component 4. Finally, the hydraulic telescopic cylinder 53 is used to drive the feeding installation plate 52 to slide into the upper part of the lower die base 12. During this process, the clamping component 4 is smoothly clamped into the upper die base 13 to complete the installation of the punch 22 (after the installation of the punch 22 is completed, the position of the clamping component 4 can be fixed by using bolts in conventional technologies). After the punch 22 is installed, the operator can smoothly fix the female die 21 on the feeding installation plate 52.

[0065] During the processing, the hydraulic telescopic cylinder 53 is used to drive the feeding installation plate 52 to move back and forth between the lower die base 12 and the positioning seat 51. During this process, the operator can place the plate to be processed on the female die 21 by using equipment such as overhead cranes and forklifts, and take out the manufactured elbow split body 6, so as to continuously complete the manufacturing work of the elbow split body 6.

[0066] In this specific embodiment, a die cavity is formed on the top of the female die 21, and the longitudinal section of the die cavity is semi-circular, and the whole die cavity is in a bent tube shape, and the punch 22 is adapted to the die cavity.

[0067] In this specific embodiment, bolt holes are evenly distributed on the feeding installation plate 52, and an installation seat is arranged at the bottom of the female die 21. The installation seat can be locked to the bolt holes of the feeding installation plate 52 by bolts, so that the female die 21 is fixed on the top of the feeding installation plate 52.

[0068] In order to quickly complete the precise docking of the clamping component 4 with the T-shaped clamping groove 131 of the upper die base 13, thereby improving the installation efficiency of the punch 22 and reducing the labor intensity of the operator. (It can be understood that after the processing die 2 is transferred to the feeding and installation plate 52 by a traveling crane, if the installation of the punch 22 is completed in the manner described above, the key point lies in how to make the clamping component 4 correspond to the T-shaped clamping groove 131 of the upper die base 13, that is, during this process, the operator needs to adjust the position and angle of the processing die 2 to make the clamping component 4 correspond to the T-shaped clamping groove 131 of the upper die base 13. However, due to the large weight of the processing die 2, although assisted by a traveling crane during this process, the overall adjustment work has a relatively large labor intensity)

[0069] Therefore, the present invention specially designs the clamping component 4 to reduce the labor intensity of the operator and improve the installation efficiency. Specifically, as Figures 5 - 13 shown, in this embodiment, the clamping component 4 includes a movable clamping plate 41, an installation substrate 42, and a connection structure 43 arranged between the movable clamping plate 41 and the installation substrate 42. There is a movable gap 44 between the movable clamping plate 41 and the installation substrate 42, and a T-shaped clamping strip 411 corresponding to the T-shaped clamping groove 131 is arranged at the top of the movable clamping plate 41;

[0070] A strip-shaped connection groove 421 is penetrated and opened at the central position of the installation substrate 42. The strip-shaped connection groove 421 includes an upper groove body 4211 and a lower groove body 4212. The longitudinal section of the upper groove body 4211 is smaller than the longitudinal section of the lower groove body 4212;

[0071] The connection structure 43 includes a connection column 431 vertically fixed to the bottom of the movable clamping plate 41. The connection column 431 passes through the upper groove body 4211 and is fixedly connected with a limit disk 432. The diameter of the connection column 431 is equal to the width of the upper groove body 4211, and the diameter of the limit disk 432 is equal to the width of the lower groove body 4212 (refer to Figure 14 shown), and handles are symmetrically arranged on both sides of the movable clamping plate 41.

[0072] Based on the above settings in this embodiment, during the installation of the punch 22, the operator only needs to make the clamping component 4 of the punch 22 roughly correspond to the T-shaped clamping groove 131 of the upper die base 13 during the process of transferring the processing die 2 to the feeding and installation plate 52 by a traveling crane. The precise docking work between the clamping component 4 and the T-shaped clamping groove 131 of the upper die base 13 can be realized by subsequently adjusting the position and angle of the movable clamping plate 41. Thus, the labor intensity of the operator is greatly reduced, and the installation efficiency of the punch 22 is improved.

[0073] Specifically, in combination with the attachedFigure 9 , Figure 12 and Figure 14 As shown in Figure 14 , since the movable clamping plate 41 is connected to the mounting substrate 42 (strip-shaped connecting groove 421) through the connecting structure 43 (connecting column 431 and limiting disc 432), the movable clamping plate 41 can be finely adjusted relative to the mounting substrate 42 in the left-right, up-down, and circumferential directions, so as to facilitate the docking of the T-shaped clamping strip 411 of the movable clamping plate 41 with the T-shaped clamping groove 131.

[0074] Since the movable clamping plate 41 and the mounting substrate 42 will move relative to each other, in order to ensure that they can correspond to each other and remain relatively stationary after installation, so as to ensure that the punch 22 and the die 21 can perform normal die closing.

[0075] For this reason, in combination with Figure 11 , Figure 14 and Figure 15 As shown, in this embodiment, the clamping assembly 4 further includes a correction member 45 disposed between the movable clamping plate 41 and the mounting substrate 42. The correction member 45 includes correction columns 451 arranged in a rectangular array and fixed to the bottom of the movable clamping plate 41. A rolling ball is embedded at the bottom of the correction column 451. A conical groove 452 is formed at the top of the mounting substrate 42 corresponding to the position of the correction column 451. And when the bottom surface of the movable clamping plate 41 is attached to the top surface of the mounting substrate 42, the rolling ball of the correction column 451 abuts against the central position at the bottom of the conical groove 452.

[0076] In combination with Figures 10 - 13 As shown, in this embodiment, the clamping assembly 4 further includes a positioning plugging plate 46 disposed between the movable clamping plate 41 and the mounting substrate 42. The positioning plugging plate 46 includes plugging portions 461 symmetrically arranged on both sides of the connecting column 431 and a connecting portion 462 connected to one end of a pair of plugging portions 461. Among them, a plugging groove adapted to the plugging portion 461 is formed between the movable clamping plate 41 and the mounting substrate 42. The plugging groove includes a first groove body 47 disposed on the bottom surface of the movable clamping plate 41 and a second groove body 48 disposed on the top surface of the mounting substrate 42.

[0077] Based on the above settings in this embodiment, when installing the punch 22, the operator can first pull out the positioning plugging plate 46 from between the movable clamping plate 41 and the mounting substrate 42 to release the limit between the movable clamping plate 41 and the mounting substrate 42, so as to facilitate the movable clamping plate 41 to be finely adjusted relative to the mounting substrate 42 in the left-right, up-down, and circumferential directions through the connecting structure 43. Thus, by adjusting the position and angle of the movable clamping plate 41, the precise docking of the T-shaped clamping strip 411 of the movable clamping plate 41 with the T-shaped clamping groove 131 of the upper die base 13 can be achieved;

[0078] After the T-shaped card strip 411 of the movable card connection plate 41 is butted with the T-shaped card connection groove 131 of the upper die base 13, the operator can drive the loading mounting plate 52 to move through the hydraulic telescopic cylinder 53, and drive the processing die 2 to move together through the loading mounting plate 52, so that the T-shaped card strip 411 of the movable card connection plate 41 is slowly inserted into the T-shaped card connection groove 131 of the upper die base 13. When the punch 22 moves to a suitable position, the operator can drive the lower die base 12 to move down through the control center 3 to correct the positions of the mounting substrate 42 and the movable card connection plate 41, so as to facilitate the reinsertion of the positioning plug-in plate 46 between the movable card connection plate 41 and the mounting substrate 42 to limit the two;

[0079] Specific correction principle: When the movable card connection plate 41 moves down, the correction column 451 at its bottom abuts against the inclined surface of the conical groove 452 on the mounting substrate 42 through the roller, so that the punch 22 and the mounting substrate 42 are driven to move on the loading mounting plate 52 passively. When the mounting substrate 42 is attached to the movable card connection plate 41, the rolling ball of the correction column 451 just abuts against the center position at the bottom of the conical groove 452, that is, the mounting substrate 42 drives the processing die 2 to complete the reset work of the processing die 2 with the movable card connection plate 41 as the reference; At this time, the operator can drive the upper die base 13 to reset, insert the positioning plug-in plate 46 between the mounting substrate 42 and the movable card connection plate 41, and then lock the positions of the punch 22 and the die 21 respectively through bolts, that is, complete the installation and positioning work of the processing die 2 in the previous process.

[0080] Further, the loading mounting plate 52 includes a lower bottom plate 521, an upper bottom plate 522 and a lifting assembly. The lower bottom plate 521 is slidably assembled on the positioning seat 51, and the upper bottom plate 522 is installed on the top of the lower bottom plate 521 through a lifting structure.

[0081] Based on the above design, the device can drive the upper bottom plate 522 to move through the lifting assembly, reduce the distance between the mounting substrate 42 and the movable card connection plate 41, correct the positions of the mounting substrate 42 and the movable card connection plate 41, and there is no need to adjust the movement of the upper die base 13.

[0082] Such as Figures 16 - 18As shown, in this embodiment, the lifting assembly includes four first telescopic structures 541 disposed between the lower bottom plate 521 and the upper bottom plate 522, and a second telescopic structure 542 fixedly installed at one end of the lower bottom plate 521 close to the hydraulic telescopic cylinder 53. The first telescopic structure 541 includes a cylinder block 5411, a piston 5412 movably disposed inside the cylinder block 5411, and a first movable rod 5413 vertically fixed to the top of the piston 5412 and fixedly connected to the upper bottom plate 522. The second telescopic structure 542 includes a box body 5421 fixedly connected to the lower bottom plate 521, a movable plate 5422 horizontally slidably disposed inside the box body 5421, and a second movable rod 5423 fixed to one side of the movable plate 5422 and fixedly connected to the output end of the hydraulic telescopic cylinder 53. Among them, the inside of the box body 5421 is communicated with the inside of the four cylinder blocks 5411 through pipelines; a contact plate is installed at the bottom of the lower die base 12.

[0083] Based on the above settings in this embodiment, the contact plate can be determined as the installation position of the processing die (as Figure 3 shown). When the hydraulic telescopic cylinder 53 drives the lower bottom plate 521 to move, since the punch 22 is placed on the top of the upper bottom plate 522, under the gravity of the punch 22, the first movable rod 5413 of the first telescopic structure 541 is at the bottom of its stroke. As the lower bottom plate 521 continues to move, when the lower bottom plate 521 contacts the contact plate, the lower bottom plate 521 cannot continue to move. As the hydraulic telescopic cylinder 53 continues to extend, at this time, the output end of the hydraulic telescopic cylinder 53 can push the second movable rod 5423 to move, and then the hydraulic oil inside the box body 5421 is injected into the cylinder block 5411 through the pipeline by the movable plate 5422, so that the first movable rod 5413 drives the upper bottom plate 522 to move upward, thereby moving the punch 22 upward to correct the position of the processing die 2 with the movable clamping plate 41 as a reference, without adjusting the movement of the upper die base 13.

[0084] The present invention also provides a process for the butt-welding elbow processing equipment as described above, including the following steps:

[0085] Step 1: Select a suitable processing die 2 according to requirements, and install the clamping assembly 4 on the top of the corresponding punch 22;

[0086] Step 2: Use a crane or forklift to transfer the selected processing die 2 to the top of the loading and installation plate 52. During this process, adjust the angle of the processing die 2 so that the T-shaped clamping strip 411 of the clamping assembly 4 is parallel to the sliding direction of the loading and installation plate 52;

[0087] Step 3: Drive the upper die base 13 to move through the driving mechanism 14 so that the bottom surface of the upper die base 13 and the top surface of the clamping assembly 4 are at the same height;

[0088] Step 4: Move the positioning plug-in plate 46 of the clamping assembly 4 out from between the movable clamping plate 41 and the mounting base plate 42, adjust the movable clamping plate 41 so that its T-shaped clamping strip 411 is parallel and corresponding to the T-shaped clamping groove 131, and then start the hydraulic telescopic cylinder 53 to drive the loading mounting plate 52 to slide above the lower die base 12. During this process, when the loading mounting plate 52 contacts the contact plate, the hydraulic oil in the box 5421 is introduced into the cylinder 5411 to move the upper base plate 522 upward. Under the action of the correction component 45, the position of the processing mold 2 is corrected with the movable clamping plate 41 as a reference;

[0089] Step 5: The feeding mounting plate 52 is driven to reset by the hydraulic telescopic cylinder 53, and then the positioning plug-in plate 46 is inserted between the movable clamping plate 41 and the mounting base plate 42 to limit the movable clamping plate 41 and the mounting base plate 42, thereby completing the installation of the upper mold;

[0090] Step 6: Place the processing plate on the die 21; drive the feeding mounting plate 52 to move the die 21 to the bottom of the punch 22 through the hydraulic telescopic cylinder 53, and then drive the lower die base 12 to move downward through the control center 3, so that the die 21 and the punch 22 are molded together, so that the plate between the die 21 and the punch 22 forms an elbow split 6 under the action of high pressure;

[0091] Step 7: After the two elbow parts 6 are butt-jointed, they are welded along the gap between them to obtain a butt-welded elbow (such as Figure 6 shown).

[0092] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
