Description

TECHNICAL FIELD

[0001] The present application belongs to the field of protection welding equipment, and particularly relates to a chimney titanium composite plate welding seam argon protection welding equipment. BACKGROUND

[0002] When the existing cylindrical chimney titanium composite plate is butt welded, annular welding is usually required along the joint, and in order to avoid the reaction of titanium with oxygen, nitrogen and hydrogen in the air, resulting in weld embrittlement, pore formation, color abnormality and loss of corrosion resistance, an argon protection welding equipment is usually arranged inside the cylindrical chimney titanium composite plate for protection of the weld, which is composed of a cylindrical gas bag and an argon gas input exhaust port. In use, the gas bag needs to be inflated to expand and abut against the inner wall of the cylinder, and sealing tape needs to be wrapped around the gap between the cylinder and the cylinder to reduce the overflow of argon. Then, argon is delivered into the sealed space formed between the gas bag and the cylinder wall, so that only argon exists in the cavity of the weld. As the welding progresses, the tape needs to be torn off gradually to enable annular welding.

[0003] In use, since the position of the argon gas exhaust port is fixed after the gas bag is fixed, it is necessary to use tape to seal the joint, and if the sealing of the tape is not tight, argon will leak from the position where the sealing is not tight when the welding is far away from the argon gas exhaust port, so that the cavity of the weld cannot be filled with argon, affecting the quality of the welding.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] Example 1 Reference Figures 1-5 For the first embodiment of the present application, the embodiment provides a chimney titanium composite plate weld argon shield welding equipment, which realizes the effect of position switching of argon gas spout following welding, which includes a surrounding part, including an inner ring 10 arranged inside the cylindrical titanium composite plate, the outer part of the inner ring 10 is fixedly connected with an inflatable air bag 11, the right side of the inflatable air bag 11 is fixedly connected with an air bag gas pipe 12, the inside of the inner ring 10 is fixedly connected with an argon gas pipe 13, the outer part of the inner ring 10 is rotatably connected with a rotating ring shell 14, the outer part of the rotating ring shell 14 is fixedly connected with an exhaust port 15, and the outer part of the rotating ring shell 14 is provided with a push assembly 16; a sealing part, including a connecting double ring 20 slidingly connected outside the exhaust port 15, the outer side of the connecting double ring 20 is fixedly connected with a first guide column 21, the outer part of the first guide column 21 is slidingly connected with an inclined chute block 22, the bottom of the inclined chute block 22 is fixedly connected with a connecting arm 23, the inner side of the connecting arm 23 is fixedly connected with a cover 24, and the outer part of the rotating ring shell 14 is provided with a delay assembly 25; a moving part, including a first electromagnet 30 arranged on the left side of the welding torch, the outer part of the rotating ring shell 14 is provided with a push fit assembly 31, the outer part of the rotating ring shell 14 is fixedly connected with a telescopic support rod 32, and the front of the telescopic support rod 32 is fixedly connected with a second electromagnet 33.

[0027] Specifically, the rigid inflatable air bag 11 is arranged in the inflatable air bag 11 to replace the traditional air bag sealing. After the inflatable air bag 11 is inflated, the inflatable air bag 11 tightly abuts against the inner wall of the titanium composite inner cylinder, so that the exhaust port 15 is arranged at the welded joint, and the argon gas is discharged through the exhaust port 15. Since the exhaust port 15 sprays the argon gas to the welded joint, the welded joint is always filled with the argon gas. After the welding position is changed, the position of the exhaust port 15 is changed by pushing the slide column 162. The position of the argon gas spraying is always corresponding to the welding position by rotating the exhaust port 15, so that the welding quality is not affected.

[0028] The sealing member is arranged to seal the outlet of the exhaust port 15 when the welding is about to be completed. Since there is only a local cavity at the joint of the titanium composite inner cylinder when the welding is about to be completed, the slide column 162 is pushed into the fixed shell 161. When the slide column 162 enters the fixed shell 161, the cover 24 is automatically sealed under the guidance of the first guide column 21 and the inclined groove block 22, so that the argon gas is not wasted. The cover 24 is slowly closed after the slide column 162 enters the fixed shell 161, so that the remaining local welding is also covered by the argon gas.

[0029] When the slide column 162 enters the fixed shell 161, the position of the exhaust port 15 cannot be adjusted. At this time, the second electromagnet 33 is pushed to be attached to the inner wall of the titanium composite inner cylinder. Since the first electromagnet 30 connected to the welding gun is also attached to the outer wall of the titanium composite inner cylinder, the first electromagnet 30 and the second electromagnet 33 are magnetically attracted when the first electromagnet 30 and the second electromagnet 33 are electrified, so that the first electromagnet 30 and the second electromagnet 33 are attracted to each other through the titanium composite inner cylinder. When the first electromagnet 30 on the outer side is pushed, the position of the second electromagnet 33 on the inner side is changed, so that the rotating ring shell 14 is temporarily rotated. Therefore, even if the slide column 162 cannot be pushed, the position of the exhaust port 15 can be changed at the remaining welding position, so that the argon gas is sprayed to the welding position.

[0030] Further, the pushing assembly 16 comprises the fixed shell 161 fixedly connected to the outer side of the rotating ring shell 14. The slide column 162 is fixedly connected in the fixed shell 161. The circulating groove 163 is arranged on the right side of the slide column 162. The connecting blocks are arranged on the top and the bottom of the slide column 162. The rotating ring shell 14 and the connecting blocks are fixedly connected through the spring telescopic rod 164. The guide pull rod 165 is fixedly connected to the outer side of the rotating ring shell 14.

[0031] Wherein, the slide post 162 can be fixed when pressed by the elastic force of the spring telescopic rod 164 and the pulling of the guide pull rod 165, and will not slide to the outside of the joint of the titanium composite inner cylinder again, and can be exposed again after pressing again, so that the push of the rotating ring shell 14 can be performed.

[0032] Preferably, the guide pull rod 165 is of elastic structure, and the end of the guide pull rod 165 away from the rotating ring shell 14 is embedded in the inside of the circulation groove 163. The front end of the circulation groove 163 is a concave groove concave to the back, and the center of the concave groove is dislocated with the protrusion at the front end. The protrusion at the front end is arranged below the center of the concave groove. The depth of the horizontal groove on the top of the circulation groove 163 is shallower than the rest of the change direction grooves, and the front of the horizontal groove is provided with an inclined slope. The edge of the rotating ring shell 14 is provided with a sealing ring for sealing, and the sealing ring is symmetrically arranged at the joint on both sides of the rotating ring shell 14.

[0033] It should be noted that, since the concave groove at the front end of the circulation groove 163 is in a dislocated state with the protrusion, the guide pull rod 165 will always move towards the position of the horizontal groove after bending, and when the slide post 162 is reset, the guide pull rod 165 will enter the inside of the horizontal groove first. At the same time, the sealing ring arranged at the edge of the rotating ring shell 14 can increase the friction, so that the natural rotation of the rotating ring shell 14 can be avoided.

[0034] In use, first, the inner ring 10 is placed at the center of the joint of the two titanium composite inner cylinders, and the inflation air bag 11 is inflated by the air bag gas pipe 12, so that the inflation air bag 11 is inflated and tightly abuts against the inner wall of the titanium composite inner cylinder. At this time, the inside of the rotating ring shell 14 can be injected with argon gas through the argon gas pipe 13, and the argon gas in the inside of the rotating ring shell 14 is sprayed from the inside of the exhaust port 15 to protect the welding. Since the position of the exhaust port 15 is close to the cavity of the welding, it is not necessary to paste sealing tape at the edge joint.

[0035] First, the position of the exhaust port 15 is welded, and the argon gas fills the position, so that the welding can be directly performed. When the welding at the position is completed, the slide post 162 is pushed to drive the rotating ring shell 14 to rotate through the fixed shell 161, so that the exhaust port 15 changes the position of the gas injection by rotating. When the position is changed, the gas injection at the outlet is performed. When the slide post 162 is about to rotate around the titanium composite inner cylinder, the welding is also about to rotate around the titanium composite inner cylinder. At this time, only a part is not welded, and the slide post 162 is pressed to enter the inside of the fixed shell 161. At this time, the end of the guide pull rod 165 embedded in the inside of the circulation groove 163 will slide along the circulation groove 163 obliquely and enter the concave groove at the front end of the circulation groove 163. By pulling the guide pull rod 165, the spring telescopic rod 164 will not release the pressure, and the slide post 162 is placed in the inside of the titanium composite inner cylinder, which will not affect the welding.

[0036] In summary, by rotating the rotating ring shell 14, the sliding column 162 can be pushed so that the position of the argon gas ejected from the exhaust port 15 can change with the welding position, thereby ensuring that the welding position is always filled with argon gas, while avoiding the cumbersome sealing with tape and preventing the welding quality from being affected.

[0037] Example 2 Reference Figures 6-8 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a sealing component for an argon-protected welding device for titanium composite plate weld seams in chimneys, which solves the problem that argon gas will still be ejected after welding. It includes a delay component 25, including a cylinder 251 fixedly connected to the outside of the rotating ring shell 14. The end of the connecting double ring 20 away from the exhaust port 15 is located inside the cylinder 251. A first spring 252 is provided between the back of the connecting double ring 20 and the cylinder 251. A connecting plate 253 is fixedly connected to the bottom of the sliding column 162. A circular push rod 254 is fixedly connected to the back of the connecting plate 253. A pressure block 255 is fixedly connected to the outside of the circular push rod 254. A rubber ring 256 that slides and connects to the inner wall of the cylinder 251 is fixedly connected to the outside of the pressure block 255. A second spring 257 is provided between the back of the connecting plate 253 and the pressure block 255. The inside of the cylinder 251 is provided with a circumferential friction texture, and the friction texture is evenly distributed.

[0038] Specifically, when the connecting plate 253 moves toward the sliding column 162, it pushes the circular push rod 254 to move. After the circular push rod 254 stops moving inside the cylinder 251, due to the friction between the rubber ring 256 and the inner wall of the cylinder 251, the second spring 257 slowly releases its elastic force, causing the connecting plate 253 to slowly enter the cylinder 251, thus creating a delay function. This allows the cover 24 to close with a delay after the sliding column 162 is pressed, preventing the argon gas from stopping being discharged before the welding is finished.

[0039] Furthermore, the exhaust port 15 is composed of an exhaust pipe and a raised T-shaped limiting block. The T-shaped limiting blocks are symmetrically distributed on the front of the exhaust port 15, and a limiting groove is opened inside the cover 24. The size of the T-shaped limiting block corresponds to the size of the limiting groove. An inclined groove is opened inside the inclined groove block 22, and the inclined direction of the inclined groove gradually slopes backward from top to bottom. The diameter of the first guide post 21 corresponds to the width of the inclined groove and is tightly embedded inside the inclined groove.

[0040] The T-shaped limiting block arranged on the front of the exhaust port 15 can limit the cover 24, and when the connecting double ring 20 slides to the rear, the position of the first guide column 21 changes, and the sliding of the first guide column 21 can drive the cover 24 to move to the position close to the exhaust port 15, and the design of the T-shaped limiting block and the limiting groove can make the cover 24 stably slide at the port of the exhaust port 15, and the phenomenon of deviation does not occur.

[0041] In use, when the slide column 162 is pressed to enter the inside of the fixed shell 161, it indicates that the surrounding welding is about to end, and only a small cavity is left to be welded, so when the slide column 162 slides, it drives the connecting plate 253 to slide, and the sliding connecting plate 253 preferentially pushes the circular push rod 254 to move backward and extrudes the second spring 257. When the slide column 162 stops moving, the circular push rod 254 at this time stops moving, and because there is friction between the rubber ring 256 and the inner wall of the cylinder 251, the pressing block 255 will slowly slide into the inside of the cylinder 251 under the action of the release of the elastic force of the second spring 257, which can delay the closure of the exhaust port 15 and have enough time to completely weld the remaining cavity.

[0042] And in the process of the pressing block 255 gradually entering the cylinder 251, it will contact the connecting double ring 20, thereby extruding the first spring 252 to store energy for resetting. When the connecting double ring 20 moves, it drives the first guide column 21 to move, thereby making the inclined groove block 22 drive the cover 24 to move to the position close to the exhaust port 15, until the second spring 257 stops releasing the elastic energy, at which time the exhaust port 15 stops moving and covers the surface of the exhaust port 15, at which time the argon stops discharging, and before that, the welding is directly completed.

[0043] In summary, by pressing the slide column 162 to drive the circular push rod 254 to move and extrude the second spring 257, and by using the friction between the pressing block 255 and the cylinder 251 and the cooperation between the first guide column 21 and the inclined groove block 22, the delayed closure of the exhaust port 15 can be formed, so that the argon can be delayed to stop spraying, and the process of the welding that is about to end can also be filled with argon.

[0044] Example 3 Reference Figures 9-10For the third embodiment of the present application, unlike the previous embodiment, the embodiment provides a moving component of the chimney titanium clad plate welding seam argon shielded welding equipment, solves the problem that the slide post 162 cannot change the position of the exhaust port 15 after entering the titanium clad plate inner cylinder, and comprises a pushing and fitting assembly 31, which comprises a limiting strip 311 fixedly connected to the outside of the rotating ring shell 14, a slotted sliding plate 312 slidably connected to the outside of the limiting strip 311, a trapezoidal block 313 fixedly connected to the top of the slotted sliding plate 312, and a second guide column 314 slidably connected to the inside of the slotted sliding plate 312. The front surface of the second guide column 314 is fixedly connected with a rectangular push rod 315 fixedly connected with the back of a second electromagnet 33.

[0045] Specifically, after the slide post 162 enters the inside of the fixed shell 161, a resisting force is applied to the trapezoidal block 313, so that the slotted sliding plate 312 moves, and the moving slotted sliding plate 312 is guided by the second guide column 314 to move the rectangular push rod 315 to move the second electromagnet 33 to a position close to the inner wall of the titanium clad plate inner cylinder until it can be fitted.

[0046] Further, the right side of the trapezoidal block 313 is fitted with the left side of the fixed shell 161, and the slope of the trapezoidal block 313 gradually inclines upward from front to back.

[0047] Since the trapezoidal block 313 is fitted with the fixed shell 161, when the slide post 162 moves, it can stably contact the trapezoidal block 313 and apply a resisting force to it, and the slope gradually inclining upward from front to back can stably move the slotted sliding plate 312 downward.

[0048] In use, when the slide post 162 enters the inside of the fixed shell 161, a resisting force is applied to the trapezoidal block 313, which enables the trapezoidal block 313 to push the slotted sliding plate 312 to move downward, even if the orientation of the slotted sliding plate 312 changes after the rotating ring shell 14 rotates. If the center of gravity of the slotted sliding plate 312 is downward, it can be tightly resisted by the resisting force, and if the center of gravity is not downward, it can also be moved by the resisting force. The moving slotted sliding plate 312 is guided by the second guide column 314 to move the rectangular push rod 315 to a position close to the inner wall of the titanium clad plate inner cylinder, so that the second electromagnet 33 is fitted with the inner wall. Since the first electromagnet 30 provided on the outer welding handle is always fitted with the outer wall of the titanium clad plate inner cylinder, when the first electromagnet 30 and the second electromagnet 33 are electrified, the movement of the first electromagnet 30 can drive the movement of the second electromagnet 33, thereby enabling the rotating ring shell 14 to rotate.

[0049] Therefore, when the slide post 162 enters the inside of the titanium composite plate inner cylinder and the position of the exhaust port 15 needs to be adjusted for subsequent local cavity welding, the first electromagnet 30 can drive the second electromagnet 33 to move, that is, the rotating ring shell 14 is rotated, so that the position of the argon gas spout is changed.

[0050] In summary, the slide post 162 exerts a resisting force on the trapezoidal block 313, so that the second electromagnet 33 is attached to the inner wall of the titanium composite plate inner cylinder, and through the magnetic attraction between the first electromagnet 30 and the second electromagnet 33, the exhaust port 15 can be moved locally in the case of environmental limitation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
