Description

Technical Field

[0001] The invention belongs to the technical field of welding protection, in particular to an inflatable tooling for protecting the back side of a stainless steel plate welding. Background Art

[0002] During the stainless steel welding process, the oxygen on the back will react with the tungsten electrode (especially in TIG welding) or the molten metal, causing the weld to oxidize and turn black, and even produce defects such as pores. These defects will seriously affect the quality and appearance of the welding. Usually, an inert gas layer is formed through inflation protection to effectively isolate pollutants such as oxygen, nitrogen, and water vapor in the air, preventing them from entering the welding area, thereby protecting the weld from contamination.

[0003] However, spraying inert gas directly on the back of the weld to protect the weld will result in a waste of inert gas.

[0004] However, the practice of directly spraying inert gas on the back of the weld to protect the weld will actually lead to a large amount of inert gas waste. Although this direct blowing method can provide a certain degree of protection, due to the lack of effective gas control and guidance, a large amount of inert gas will diffuse rapidly during the welding process, which will not only lead to the waste of inert gas but also affect the protection of the welding process.

[0005] To this end, the present invention provides a stainless steel plate welding back side protection inflatable tooling. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 7 As shown, a stainless steel plate welding back side protection inflatable tooling according to an embodiment of the present invention comprises a workbench 1, an inert gas tank 5 and a stainless steel plate body 2. The positions where the grooves are opened on the two stainless steel plate bodies 2 are aligned and then placed on the table top of the workbench 1 for welding.

[0035] The working groove 25 is provided at the top of the working table 1 and is located below the welding seam on the stainless steel plate body 2;

[0036] The welding part needs to be located above the working groove 25 to facilitate the release of inert gas to the back of the weld to ensure the quality of the weld.

[0037] The placement box 7 is fixedly installed inside the working tank 25, and a blowing box 18 is slidably installed inside the placement box 7. A blowing pipe 19 is provided at the top of the blowing box 18, and the blowing box 18 is connected to the inert gas tank 5;

[0038] There are multiple blow pipes 19, all of which are arranged at the top of the blow box 18. The inert gas can be transported to the inside of the blow box 18 through the inert gas tank 5, and then the inert gas is sprayed on the back of the weld by the multiple blow pipes 19 to maintain the quality of welding.

[0039] A placing cylinder 3 is fixedly mounted inside the working groove 25, and a placing ring 4 for placing a welding gun is slidably mounted on the placing cylinder 3;

[0040] Before welding, the worker needs to insert the head of the welding gun through the inside of the placement ring 4 and then weld the stainless steel plate body 2. At this time, the placement ring 4 will be pulled out from the inside of the placement tube 3 as the welding gun moves.

[0041] The control component is arranged at the top of the workbench 1, and is used to control the sliding of the blow box 18 inside the placement box 7. The sliding of the blow box 18 can be controlled by the set control component, so that follow-up blowing can be performed according to the welding position, which can effectively reduce the waste of inert gas and make the utilization rate of inert gas higher.

[0042] The cooperative component is arranged inside the placement tube 3, and is used for synchronizing the sliding of the blowing box 18 with the placement ring 4. The moving trajectory of the blowing box 18 can be synchronized with the moving trajectory of the placement ring 4 through the arranged cooperative component, so that the inert gas sprayed by the blowing box 18 can be sprayed in real time following the welding position, thereby reducing the waste of inert gas and improving the utilization rate of inert gas.

[0043] It is a preferred embodiment of the present invention, the control component includes a spiral transmission rod 9 and a slider 17, the slider 17 is fixedly installed at the bottom end of the blowing box 18, the spiral transmission rod 9 is rotatably installed inside the placement box 7, and the slider 17 is slidably installed on the outer wall of the spiral transmission rod 9.

[0044] A spiral groove is provided on the spiral transmission rod 9, which cooperates with the protrusion set inside the slider 17. Therefore, when the spiral transmission rod 9 rotates, the protrusion slides inside the spiral groove, which can drive the slider 17 to control the blowing box 18 to slide on the outer wall of the spiral transmission rod 9. By controlling the rotation direction of the spiral transmission rod 9, the sliding direction of the blowing box 18 can be controlled.

[0045] It is a preferred embodiment of the present invention. The cooperative component includes a rotating rod 10, a connecting tube 11, a first bevel gear 13 and a second bevel gear 14. The rotating rod 10 is rotatably installed inside the placement tube 3, and one end extends out of the bottom end of the placement tube 3. The connecting tube 11 is wrapped around the outer wall of the rotating rod 10. One end of the connecting tube 11 is fixedly connected to the inside of the placement tube 3, and the other end is fixedly connected to the placement ring 4. The first bevel gear 13 is fixedly installed on the outer wall of the rotating rod 10. The second bevel gear 14 is fixedly installed on one end of the spiral transmission rod 9 close to the rotating rod 10. The first bevel gear 13 is meshed with the second bevel gear 14.

[0046] When the placement ring 4 is located inside the placement tube 3, pulling the placement ring 4 can drive the rotating rod 10 to rotate by pulling the connecting tube 11. When the rotating rod 10 rotates, the first bevel gear 13 and the second bevel gear 14 can be driven to rotate. Therefore, the blowing box 18 can be controlled to slide on the outer wall of the spiral transmission rod 9 at the same time. Therefore, when the welding gun is placed on the placement ring 4 and the welding work is started, the connecting tube 11 can be pulled to rotate the rotating rod 10. Through the cooperation of the first bevel gear 13 and the second bevel gear 14, the blowing box 18 is driven to slide at the same time. Therefore, the inert gas can be sprayed along the weld, which not only reduces the waste of inert gas, but also improves the use effect of the inert gas.

[0047] This is a preferred embodiment of the present invention. A coil spring 15 is fixedly connected to the bottom end of the rotating rod 10 , and the other end of the coil spring 15 is fixedly connected to the inside of the workbench 1 .

[0048] When the placement ring 4 is located inside the placement tube 3, the coil spring 15 does not deform. When the placement ring 4 is pulled out from the placement tube 3, the connecting tube 11 will drive the rotating rod 10 to rotate. At the same time, the rotating rod 10 will also cause the coil spring 15 to rotate and deform, and store elastic potential energy. Therefore, when the welding is completed, you only need to take the welding gun out of the placement ring 4. At this time, the coil spring 15 will release the elastic potential energy, drive the rotating rod 10 to reset and rotate, and at the same time, reel the connecting tube 11 to pull the placement ring 4 back to the inside of the placement tube 3.

[0049] This is a preferred embodiment of the present invention. An air inlet pipe 6 is fixedly installed at one end of the placement box 7 away from the placement tube 3. The inert gas tank 5 is connected to the air inlet pipe 6 through a hose. A bellows 8 is fixedly installed at one end of the air inlet pipe 6 away from the hose. The other end of the bellows 8 is fixedly connected and conducted to the blowing box 18.

[0050] The inert gas tank 5 delivers the inert gas to the inside of the air inlet pipe 6 through a hose, and then enters the inside of the blowing box 18 through the bellows 8. The bellows 8 can solve the problem of the sliding distance of the blowing box 18 and ensure the normal operation of the equipment.

[0051] This is a preferred embodiment of the present invention. A piston cylinder 23 is fixedly installed inside the workbench 1, and a piston 22 is slidably installed inside the piston cylinder 23. A first tube 16 and a second tube 24 are fixedly connected to the piston cylinder 23. One end of the first tube 16 extends to the inside of the connecting tube 11, and one end of the second tube 24 extends out of the outer wall of the workbench 1. Both the first tube 16 and the second tube 24 are provided with a one-way valve.

[0052] The one-way valve disposed on the first tube 16 can block the direction in which the first tube 16 flows back to the piston cylinder 23 , and the one-way valve disposed on the second tube 24 can block the direction in which the piston cylinder 23 flows toward the second tube 24 .

[0053] When the piston 22 slides upward inside the piston cylinder 23, the external gas can be sucked into the piston cylinder 23 through the second tube 24. Then, the piston 22 is controlled to slide downward inside the piston cylinder 23, so that the gas inside the piston cylinder 23 can be transported to the inside of the first tube 16 and finally to the inside of the connecting tube 11.

[0054] This is a preferred embodiment of the present invention. An impeller 20 is rotatably installed inside the air inlet pipe 6. A transmission rod 26 is fixedly installed at the bottom end of the impeller 20. A sliding rod 21 is threadedly connected to the outer wall of the transmission rod 26. The end of the sliding rod 21 away from the impeller 20 is fixedly connected to the piston 22.

[0055] When the inert gas tank 5 delivers the inert gas to the inside of the intake pipe 6, the high-pressure inert gas will impact the impeller 20, causing the impeller 20 to drive the transmission rod 26 to rotate. The transmission rod 26 is provided with a reciprocating thread groove. Therefore, when the transmission rod 26 rotates, the slide bar 21 can slide back and forth up and down on the outer wall of the transmission rod 26, and at the same time, it can drive the piston 22 to slide back and forth inside the piston cylinder 23. Through the reciprocating sliding of the piston 22, the external gas can be continuously sucked into the piston cylinder 23, and then the sucked gas can be pushed out of the first tube 16.

[0056] This is a preferred embodiment of the present invention, the placement ring 4 is hollow, and an air nozzle 12 is provided on the placement ring 4, and the air nozzle 12 is inclined.

[0057] Through the reciprocating sliding of the piston 22, the external gas can be continuously sucked into the piston cylinder 23, and then the sucked gas can be pushed out into the first tube 16, and then it can enter the interior of the connecting tube 11 and be transported to the inner cavity where the ring 4 is placed. The dust on the welding track can be sprayed through the inclined air nozzle 12. At the same time, the one-way valves arranged on the first tube 16 and the second tube 24 can also be reversely arranged. In this way, the opening of the air nozzle 12 can be in a negative pressure state, and the welding track can be sucked, and the dust on the stainless steel plate body 2 or in the air can be absorbed, thereby improving the welding quality and the air quality.

[0058] Working principle: by passing the head of the welding gun through the interior of the placement ring 4, and then welding the stainless steel plate body 2, the placement ring 4 will be pulled out from the interior of the placement tube 3 as the welding gun moves, and the rotating rod 10 is driven to rotate by pulling the connecting tube 11, which can drive the first bevel gear 13 and the second bevel gear 14 to rotate, so that the spiral transmission rod 9 rotates, and the blowing box 18 is controlled to slide on the outer wall of the spiral transmission rod 9. At this time, the blowing box 18 that sprays inert gas can follow the weld to spray in real time, which can not only reduce the waste of inert gas, but also improve the use effect of inert gas.

[0059] When the inert gas is delivered to the inside of the air inlet pipe 6 through the inert gas tank 5, the high-pressure inert gas will impact the impeller 20, so that the impeller 20 drives the transmission rod 26 to rotate. A reciprocating thread groove is provided on the transmission rod 26. Therefore, when the transmission rod 26 rotates, the slide bar 21 can slide back and forth up and down on the outer wall of the transmission rod 26, and at the same time, it can drive the piston 22 to slide back and forth inside the piston cylinder 23. Through the reciprocating sliding of the piston 22, the external gas can be continuously sucked into the piston cylinder 23, and then the sucked gas can be pushed out of the first tube 16, and then it can enter the inside of the connecting tube 11 and be delivered to the inner cavity where the ring 4 is placed. The dust on the welding track can be sprayed through the inclined air nozzle 12, so as to further improve the welding effect.
