Description

Technical Field

[0001] The present invention relates to the technical field of pressure vessels, and more particularly to a welding device and method for pressure vessels. Background Art

[0002] Submerged arc welding machines are widely used for butt welding of pressure vessel shells and heads. Submerged arc welding is an efficient and automated arc welding method that uses an arc burning under a flux layer to weld metals. The arc produced by submerged arc welding is completely covered by granular flux during welding, so there is no arc light and spatter exposed, and the welding process is quiet and environmentally friendly.

[0003] During the welding process, the flux is spread sufficiently, and most of the flux only covers the arc and protects the molten pool, and does not directly participate in the formation of the weld. Therefore, most of the flux can be recycled. The roller frame is usually used in conjunction with automatic welding equipment such as a submerged arc welding machine. The flux spread on the joint will naturally fall off as the roller frame drives the pressure vessel to rotate. When welding pressure vessels, traditional submerged arc welding machines usually simply place boxes at the bottom of the roller frame to recover the fallen flux. However, during the welding process, part of the flux will be melted and hardened by the high temperature of the arc, and mixed with the unused flux. This situation not only reduces the recycling efficiency of the flux, but may also cause blockage of the flux delivery device, affect the subsequent welding quality, and increase the complexity of subsequent processing. Therefore, it is necessary to propose a welding device and method for pressure vessels to solve the above problems. Summary of the invention

[0014] As a preferred embodiment of the present invention, a welding method for a pressure vessel welding device comprises the following steps: S1: The end cap and the cylinder are aligned and placed on the auxiliary wheels between the two clamps, and the adjustment motor is started. The adjustment motor drives the clamp to move through the screw rod to stabilize the end cap and the cylinder; S2: Start the submerged arc welding machine, sprinkle the flux on the gap between the head and the cylinder, drive the driving motor to drive the driving wheel to rotate, thereby driving the head and the cylinder to rotate, and the submerged arc welding machine welds the weld; S3: The driving wheel drives the head and the cylinder to rotate and drives the crushing mechanism to knock the head and the cylinder, which not only plays a role in preliminarily crushing the agglomerated flux to disperse it, but also makes the flux fall into the box quickly through knocking and vibration; S4: The rotation of the driving wheel will also drive the screening mechanism to reciprocate.

[0015] Compared with the prior art, the advantages of the present invention are: 1. A recovery mechanism for recovering flux is arranged on one side of the base, and a receiving box with one end that can swing is arranged inside the box body, which is used for initially receiving the flux after submerged arc welding, and the rotation of the driving wheel drives the slide plate to slide back and forth, so that the receiving box swings, and when the slide plate causes the receiving box to swing downward, the flux falls into the screening frame, and when the slide plate makes the receiving box horizontal, the flux is stopped from being released, so that it can ensure that the receiving box collects a sufficient amount of flux, and the screening frame can screen the flux in batches to avoid the accumulation of flux, thereby improving the screening effect and ensuring the screening quality; during the sliding process of the screening frame, the vibration plate causes the screening frame to vibrate, so as to speed up the available flux to quickly pass through the screening frame and enter the recycling box, and when the other end of the screening frame slides to the top of the waste box, the ejector pushes the door panel to rotate, so that the other end of the screening frame is opened, and the block flux that cannot be filtered is transported to the waste box, thereby completing the classification and recovery of the flux, quickly screening out the flux that can be reused, and improving the efficiency of the flux.

[0016] 2. The driving wheel is used to drive the first lever and the first lever to move in a circle, and the curved rod can also be driven to move back and forth in a cycle, so that the pressure plate can cyclically knock the head and the cylinder, which not only accelerates the rolling of the granular flux, but also can preliminarily break up the agglomerated flux, facilitate the transportation of the receiving mechanism and the screening of the screening mechanism, thereby improving the screening efficiency.

[0017] 3. Use the slide plate to drive the slider to slide back and forth in the chute, drive the crushing roller to roll inside the receiving box, so as to further crush the flux initially crushed by the crushing mechanism, disperse the flux as much as possible, reduce the screening difficulty of the screening mechanism, and recycle as much reusable flux as possible to improve the screening effect; similarly, use the slider to slide inside the chute, and drive the wedge to slide by the rotating plate, which can drive the top column inside the discharge door to hit the push plate multiple times, so that the push plate repeatedly bounces the flux near the discharge door, disperses the flux, reduces the accumulation of flux, and thus facilitates the crushing roller to crush the flux and improves the effect of the crushing roller to crush the flux.

[0025] The screening mechanism 5 also includes a support shaft 51 installed on the side of the support frame 37, and a lever 52 is rotatably connected to the support shaft 51. Both ends of the lever 52 are penetrated with an adjustment slot 53, and the second lever 393 is slidably connected to the adjustment slot 53 at the top of the lever 52. The side protrusion of the slide plate 54 is slidably connected to the adjustment slot 53 at the bottom of the lever 52. Two side plates 56 are symmetrically installed on the top surface of the slide plate 54. Two first shafts 57 are symmetrically installed on the other end of the screening frame 55. The first torsion spring 58 is installed on the first shaft 57. The two first shafts 57 are elastically connected to the inside of the two ends of the door plate 59 through the first torsion spring 58. Two push plates 591 are symmetrically fixed on the top surface of the door plate 59. The bottom surface of the other end of the screening frame 55 is rotatably connected to a roller 592, and the roller 592 resists the vibration plate 36. A limiting mechanism 6 is installed inside the other end of the screening frame 55, and the limiting mechanism 6 includes a second spring 61 and a rack 62 installed inside the other end of the screening frame 55. The rack 62 is elastically connected to the inside of the other end of the screening frame 55 through the second spring 61, and the bottom end of the rack 62 protrudes from the bottom surface of the screening frame 55. A swing gear 63 is rotatably connected inside the other end of the screening frame 55, and the swing gear 63 is meshed with the corresponding rack 62. A limiting block 64 is fixed on the side of the swing gear 63, and the limiting block 64 abuts against the door panel 59.

[0026] A receiving mechanism 7 is installed inside the box body 31, and the receiving mechanism 7 includes a receiving box 71 installed above the slide plate 54, a second shaft 72 is installed at one end of the receiving box 71, a second torsion spring 73 is sleeved on the second shaft 72, and the second shaft 72 is elastically connected to the inside of the box body 31 through the second torsion spring 73, two slide grooves 74 are symmetrically provided on both sides of the receiving box 71, and lifting rods 75 and third springs 76 are installed on both sides of the receiving box 71. The lifting rods 75 are elastically connected to the inside of the receiving box 71 through the third spring 76, and the other end of the receiving box 71 is slidably connected to a discharge door 77, and the two ends of the discharge door 77 are installed at the ends of the two lifting rods 75.

[0027] First, align the end cap 22 and the cylinder 23 and place them on several auxiliary wheels 15 between the two clamps 14. The auxiliary wheels 15 lift the end cap 22 and the cylinder 23. Then start the adjustment motor 12, and drive the two clamps 14 to approach each other through the rotation of the screw rod 13, so as to stabilize the end cap 22 and the cylinder 23. A rotatable disc is provided on the clamp 14. When the clamp 14 clamps the end cap 22 and the cylinder 23, the disc contacts the surface of the end cap 22 and the cylinder 23. When the driving wheel 39 drives the end cap 22 and the cylinder 23 to rotate, the disc rotates synchronously, so as to ensure that when the end cap 22 and the cylinder 23 rotate, the clamp 14 can still stabilize the end cap 22 and the cylinder 23. Start the submerged arc welding machine 21 and the drive motor 38. The submerged arc welding machine 21 sprays the flux on the joint of the head 22 and the cylinder 23. At the same time, the drive motor 38 drives the drive wheel 39 to rotate, and the head 22 and the cylinder 23 roll on the auxiliary wheel 15. With the uniform rotation of the head 22 and the cylinder 23 (the rotation speed is relatively slow), the flux is evenly sprinkled on the weld, and the submerged arc welding machine 21 welds the weld. Finally, the flux naturally falls into the box 31 on one side of the base 11 as the head 22 and the cylinder 23 rotate. A receiving mechanism 7 is provided at the top of the box 31. The fallen flux first falls into the receiving box 71. One end of the receiving box 71 is rotatably connected to the inner wall of the box 31 through the second shaft 72 (as shown in the attached manual). Figure 6As shown in FIG. 1 , one end here refers to the left end of the receiving box 71). A screening mechanism 5 is arranged in the box body 31 below the receiving mechanism 7, and a disc 391 is installed at one end of the driving wheel 39 rotating on the top of the support frame 37, and a first lever 392 and a second lever 393 are installed on the disc 391. The slide plate 54 and the second lever 393 are transmitted through the lever 52, that is, the convex column on the side of the slide plate 54 and the second lever 393 are respectively slidably connected to the adjustment grooves 53 at both ends of the lever 52. When the driving wheel 39 drives the disc 391 to rotate, the second lever 393 drives the upper end of the lever 52 to swing back and forth through the matching adjustment groove 53, so that the lever 52 swings back and forth around the support shaft 51, so that the lower end of the lever 52 drives the slide plate 54 to slide back and forth on the sliding frame 35 in the box body 31.

[0028] During the sliding process of the slide plate 54, the side plate 56 is driven to move synchronously, and the side plate 56 drives the corresponding slider 81 to slide in the slide grooves 74 on both sides of the receiving box 71. Figure 6 The lifting rod 75 is raised, and the third spring 76 is compressed, and the discharge door 77 is driven to rise, so that there is a gap between the bottom surface of the other end of the receiving box 71 and the discharge door 77, and the flux in the receiving box 71 rolls down and falls into the screening frame 55. The screening frame 55 is inclined, and its bottom is a metal mesh through which flux particles that can be continuously used can pass. The flux that falls into the screening frame 55 continues to roll toward the other end of the screening frame 55, thereby avoiding flux accumulation, which helps to quickly screen the flux, and in the process of flux rolling down, the flux that can be continuously used directly passes through the bottom surface of the screening frame 55 and falls into the recycling box 32. The flux with larger particles cannot pass through the bottom surface of the screening frame 55 and eventually rolls to the other end and is intercepted by the door panel 59.

[0029] After the receiving box 71 is tilted, the lever 52 continues to drive the slide plate 54 to slide, and the slide plate 54 drives the screening frame 55 to slide to the right of the slide slot 74, and the side plate 56 drives the slider 81 to slide inside the slide slot 74. Since the slide plate 54 slides horizontally, the height of the side plate 56 remains unchanged during the movement. Therefore, as the side plate 56 drives the slider 81 to slide rightward in the slide slot 74, the receiving box 71 will gradually rotate to a horizontal position. During the rotation of the receiving box 71, the second shaft 72 rotates with the inside of the box body 31, and the second torsion spring 73 accumulates force. After the slider 81 slides to the narrowing point of the lifting rod 75, it will no longer interfere with the lifting rod 75. Subsequently, the lifting rod 75 slides downward under the elastic force of the third spring 76, and drives the discharge door 77 to slide synchronously, thereby closing the other end of the receiving box 71. The receiving box 71 gradually tends to a horizontal state, and after the other end of the receiving box 71 is closed by the discharge door 77, the flux that falls from the weld of the cylinder 23 into the receiving box 71 will no longer roll into the screening frame 55. This can ensure that the receiving box 71 collects a sufficient amount of flux, and the screening frame 55 can screen the flux in batches to avoid flux accumulation, thereby improving the screening effect and ensuring the screening quality.

[0030] When the lever 52 drives the slide plate 54 and the screening frame 55 to slide to the right, since the screening frame 55 and the slide plate 54 are rotationally connected, and the roller 592 at the bottom of the screening frame 55 rolls on the top of the vibration plate 36, the ups and downs of the vibration plate 36 make the screening frame 55 vibrate up and down during the sliding process, thereby accelerating the screening of the flux inside the screening frame 55 and greatly improving the classification efficiency and effect. A waste box 33 is installed on the right side of the recycling box 32. The top surface of the waste box 33 is higher than the top surface of the recycling box 32, and the heights of the two are smoothly transitioned. When the right end of the screening frame 55 slides from above the recycling box 32 to above the waste box 33, the higher top of the waste box 33 contacts and squeezes the rack 62 protruding from the bottom surface of the right end of the screening frame 55, so that the rack 62 slides into the inside of the screening frame 55. The rack 62 compresses the second spring 61 and drives the swing gear 63 to rotate. The swing gear 63 drives the limit block 64 to swing, so that the door panel 59 that originally contacts the outside of the door panel 59 is released. The limit block 64 that cannot be turned over rotates to the inside of the side of the screening frame 55, releasing the restriction on the door panel 59. Then the sliding of the screening frame 55 causes the ejector pin 34 installed on the inner side of the box body 31 to contact the push plate 591, so that the door panel 59 is reversed around the first axis 57. The door panel 59 causes the first torsion spring 58 to accumulate force and opens the right end of the screening frame 55. The block flux that cannot be screened and rolls to the right end of the screening frame 55 falls from the right end of the screening frame 55 into the waste box 33, thereby completing the classification and recovery of the flux, quickly screening out the flux that can be reused, and improving the efficiency of flux use.

[0031] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 11A crushing mechanism 4 is installed at the top of the support frame 37. The crushing mechanism 4 includes a shell 41 installed at the top of the support frame 37. A first spring 42 is installed inside the shell 41. A curved rod 43 is slidably connected to the shell 41. The curved rod 43 penetrates the shell 41, and the curved rod 43 is elastically connected to the shell 41 through the first spring 42. One end of the curved rod 43 abuts against the first shifting rod 392, and a pressure plate 44 is installed at the other end of the curved rod 43.

[0032] When the driving wheel 39 drives the disc 391 to rotate, a plurality of first levers 392 and second levers 393 in a circular array on the surface of the disc 391 push the bottom end of the curved rod 43 in turn, causing the curved rod 43 to slide. During the sliding of the curved rod 43, the first spring 42 inside the shell 41 is compressed. When the first lever 392 or the second lever 393 that has abutted against the bottom end of the curved rod 43 no longer abuts, the curved rod 43 is quickly reset under the elastic force of the first spring 42, thereby driving the pressure plate 44 to knock on the surfaces of the head 22 and the cylinder 23, which can not only accelerate the rolling of the granular flux, but also preliminarily break the flux that has melted together due to the high temperature, and preliminarily break up the agglomerated flux, thereby facilitating the transportation of the receiving mechanism 7 and the screening of the screening mechanism 5, thereby improving the screening efficiency.

[0033] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 11 A crushing mechanism 8 is installed inside the receiving box 71. The crushing mechanism 8 includes two sliders 81 that are slidably connected to the inside of each slide groove 74, and each slider 81 is rotatably connected to the top of the corresponding side plate 56. A connecting plate 82 is installed at the top of the slider 81. The other end of the connecting plate 82 is rotatably connected to one end of a crushing roller 83, and the crushing roller 83 is rollingly connected to the inside of the receiving box 71. A rotating plate 84 is installed at the bottom end of the slider 81. A third shaft 85 is installed at one end of the rotating plate 84. A third torsion spring 86 is sleeved on the third shaft 85, and the rotating plate 84 is elastically connected to the bottom of the slider 81 through the cooperation of the third shaft 85 and the third torsion spring 86. A spring sheet 87 is installed inside the bottom end of the slider 81, and the two ends of the spring sheet 87 respectively contact the inner wall of the slider 81 and the inner wall of the rotating plate 84.

[0034] The two sides of the receiving box 71 are provided with a spring mechanism 9, which includes a plurality of inclined grooves 91 equidistantly arranged at the bottom of the slide groove 74, and a wedge block 92 is slidably connected in the inclined groove 91. A slide bar 93 and a fourth spring 94 are installed inside the two sides of the receiving box 71. The slide bar 93 is elastically connected to the inside of the receiving box 71 through the fourth spring 94. A plurality of slide columns 95 are equidistantly installed on the top surface of the slide bar 93, and each wedge block 92 is sleeved on the top of the corresponding slide column 95. A tooth plate 96 is fixed to the other end of the slide bar 93, and the discharge door 77 A rotating shaft 97 is internally connected for rotation, and transmission gears 98 are installed at both ends of the rotating shaft 97, and the transmission gears 98 are meshed and connected with the corresponding tooth plates 96. A number of cams 99 are equidistantly installed on the rotating shaft 97, and a number of shift blocks 991 are equidistantly installed inside the discharge door 77, and each cam 99 abuts against the corresponding shift block 991. A top column 992 is fixed to the top side of each shift block 991, and a fifth spring 993 is sleeved on the top column 992. The shift block 991 is elastically connected to the inside of the discharge door 77 through the corresponding fifth spring 993.

[0035] When the side plate 56 drives the slider 81 to slide back and forth in the slide groove 74, the slider 81 drives the crushing roller 83 to roll inside the receiving box 71 through the connecting plate 82, crushing the flux inside the receiving box 71, so that the flux initially broken up by the crushing mechanism 4 is further crushed, and the flux particles that are not firmly adhered are removed as much as possible, so as to be recycled and reused, thereby reducing the screening difficulty of the screening mechanism 5 and improving the screening efficiency.

[0036] Since the receiving box 71 is in the process of rotating from the inclined state to the horizontal state, and during this process, the flux continues to fall into the receiving box 71, it is inevitable that some of the flux will roll to the right end of the receiving box 71 and accumulate near the discharge door 77. Therefore, after the slider 81 slides to the right in the slide slot 74 and no longer interferes with the lifting rod 75, the discharge door 77 falls to reclose the right end of the receiving box 71, and after the discharge door 77 is reset, the transmission gears 98 on both sides thereof are re-engaged with the corresponding toothed plates 96. Then, the rotating plate 84 at the bottom of the slider 81 contacts the several wedge blocks 92 at the bottom of the slide groove 74 one by one. In this direction of movement, the rotating plate 84 is engaged with the corresponding wedge blocks 92 and will not rotate around the third axis 85, that is, the rotating plate 84 will not rotate. Therefore, in this direction, the rotating plate 84 pushes the wedge blocks 92 to slide in the corresponding inclined groove 91, and the wedge blocks 92 drive the slide rod 93 to slide inside the side of the receiving box 71 through the slide column 95. The slide rod 93 stretches the fourth spring 94 and drives the toothed plate 96 at the other end thereof to slide. The toothed plate 96 drives the rotating shaft 97 to rotate inside the discharge door 77 through the transmission gear 98. The rotating shaft 97 drives several shifting block cams 99 to rotate. During the rotation of 99, the shift block 991 is pushed away from the push plate 994, and the shift block 991 drives the top column 992 to slide, and the fifth spring 993 accumulates force. When the cam 99 no longer contacts the shift block 991, under the elastic force of the fifth spring 993, the cam 99 and the shift block 991 are synchronously close to the push plate 994 and contact the push plate 994, so that the top of the push plate 994 rotates around the side of the discharge door 77. The violent flipping of the push plate 994 will push the flux gathered at the right end of the receiving box 71, so that the flux is quickly dispersed to the middle of the receiving box 71, reducing the accumulation of flux, thereby facilitating the crushing roller 83 to crush the flux and improving the effect of the crushing roller 83 in crushing the flux. Since the inclined groove 91 is a gradually deepening inclined groove (as shown in the attached manual), the flux accumulated at the right end of the receiving box 71 is pushed away from the push plate 994, and the flux is quickly dispersed to the middle of the receiving box 71, reducing the accumulation of flux, thereby facilitating the crushing roller 83 to crush the flux and improving the effect of the crushing roller 83 in crushing the flux. Figure 7 As shown in the figure, as the rotating plate 84 pushes the wedge 92 to slide, the wedge 92 gradually sinks into the chute 91 until the rotating plate 84 no longer contacts the wedge 92. The slider 81 continues to drive the rotating plate 84 to slide to the right and passes over the wedge 92. After the wedge 92 loses the restriction of the rotating plate 84, the fourth spring 94 pulls the slide bar 93 to reset. The slide bar 93 drives the wedge 92 to return to the highest point of the chute 91 through the slide column 95. The reset of the slide bar 93 causes the tooth plate 96 to drive the transmission gear 98 to reverse. The transmission gear 98 resets all other parts inside the discharge door 77 through the rotating shaft 97. After the slider rotating plate 84 contacts the next wedge 92, the above process is repeated again, so that the push plate 994 repeatedly pushes the flux to reduce the accumulation of welding near the discharge door 77 at the right end of the receiving box 71.

[0037] During the process that the slider 81 drives the rotating plate 84 to slide toward the left end of the slide slot 74, as shown in the attached manual, Fig. 9As shown, the right end of the rotating plate 84 begins to abut against the wedge block 92, and in the movement in this direction, the surface where the wedge block 92 abuts against the right end of the rotating plate 84 is an inclined surface, which is convenient for transition. After the right end of the rotating plate 84 abuts against the wedge block 92, the spring piece 87 is compressed, so that the rotating plate 84 rotates around the third axis 85, so that the third torsion spring 86 accumulates force, and the right end of the rotating plate 84 rotates into the slider 81, thereby easily crossing the wedge block 92. Therefore, when the slider 81 slides to the left, the wedge block 92 will not be pushed by the rotating plate 84.

[0038] This embodiment also discloses a welding method for a pressure vessel welding device, comprising the following steps: S1: The end cap 22 and the cylinder 23 are aligned and placed on the auxiliary wheel 15 between the two clamps 14, and the adjustment motor 12 is started. The adjustment motor 12 drives the clamp 14 to move through the screw rod 13 to stabilize the end cap 22 and the cylinder 23; S2: Start the submerged arc welding machine 21, sprinkle the flux on the gap between the sealing head 22 and the cylinder 23, drive the driving motor 38 to drive the driving wheel 39 to rotate, thereby driving the sealing head 22 and the cylinder 23 to rotate, and the submerged arc welding machine 21 welds the weld; S3: The driving wheel 39 drives the end cap 22 and the cylinder 23 to rotate and drives the crushing mechanism 4 to knock the end cap 22 and the cylinder 23, which not only plays a role in preliminarily crushing the agglomerated flux to disperse it, but also causes the flux to quickly fall into the box 31 through knocking and vibration; S4: The rotation of the driving wheel 39 also drives the screening mechanism 5 to reciprocate. When the screening mechanism 5 moves to one end of the box body 31, the receiving box 71 is tilted, so that the flux received by the receiving box 71 is poured into the screening frame 55; when the screening mechanism 5 moves to the other end of the box body 31, the receiving box 71 is restored to a horizontal level, the material discharge is stopped, and the material is received. At this time, the screening frame 55 classifies the flux, and the recyclable flux falls into the recovery box 32, and the flux that cannot be used is sent to the waste box 33; S5: During the reciprocating motion of the screening mechanism 5 , the crushing mechanism 8 is driven to roll in the receiving box 71 , thereby crushing the compacted flux and further dispersing the compacted flux, which helps to improve the screening efficiency of the screening mechanism 5 .
