Description

Technical Field

[0001] This application relates to the technical field of argon arc welding processing, and particularly relates to a protection tooling for argon arc welding splicing of titanium plates. Background Technique

[0002] Argon arc welding is a common metal welding technique. It uses argon gas as a shielding gas to protect the welding area from oxygen and water vapor in the air, thereby preventing problems such as oxidation and hydrogen embrittlement. This welding method is applicable to the welding of various metals and alloys, especially in the welding of thin-walled structures, high-demand welding joints, and occasions where high precision and good appearance are required.

[0003] When manually welding titanium plate splices with tungsten inert gas (TIG) welding, the back protection mainly relies on a person using a trailing shield to protect the welding area on the back. However, when considering the splicing of large flat plates, the spliced flat plates need to be placed on a rack or welded upright so that the back can be protected manually. The operation is complex and there is a certain degree of danger.

[0004] Therefore, those skilled in the art have provided a protection tooling for argon arc welding splicing of titanium plates to solve the problems raised in the above background technique. Utility Model Content

[0005] To solve the problems raised in the above background technique, this application provides a protection tooling for argon arc welding splicing of titanium plates.

[0006] The protection tooling for argon arc welding splicing of titanium plates provided by this application adopts the following technical solutions:

[0007] A protection tooling for argon arc welding splicing of titanium plates includes a back channel steel. End plates are provided at both ends of the back channel steel. A plurality of partition plates are also installed between the two side walls of the back channel steel. The top surface of the partition plate is flush with the top edge of the back channel steel. An air inlet pipe is installed through the front and rear end plates. Exhaust grooves are provided in sections on the air inlet pipe. A diffuser cylinder is sleeved at the part of the air inlet pipe where the exhaust grooves are provided. The position of the diffuser cylinder is between two adjacent partition plates, and a plurality of exhaust holes are evenly opened on the outer surface of the diffuser cylinder.

[0008] Preferably, an inner sleeve is also installed inside the diffuser cylinder. The inner sleeve is rotatably sleeved on the air inlet pipe, and air permeation grooves adapted to the exhaust grooves are opened on the inner sleeve. Both ends of the inner sleeve are installed on the inner wall of the diffuser cylinder through a plurality of connecting plates.

[0009] Preferably, a support block is also installed on the partition plate. The support block is slidably arranged in a slot at the center of the top end of the partition plate for supporting the spliced titanium plate.

[0010] Preferably, an adjusting rack is connected to the bottom of the partition board. An adjusting gear is meshed on the adjusting rack. The adjusting gear is rotatably installed on the partition board, and a scale line is further arranged on the side of the partition board.

[0011] Preferably, side plates are further connected to the tops of both sides of the back channel steel. The side plates are inclined from outside to inside. A high-temperature resistant rubber strip is arranged above the side plates, and the bottom of the side plates is connected to the back channel steel through rib plates.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. The back channel steel provided in the present application can form a relatively sealed space. After the titanium plates are spliced and placed in the back channel steel, the air inlet pipe can release argon into the back channel steel to protect the back of the weld and avoid phenomena such as oxidation of the weld during the welding process.

[0014] 2. A diffuser cylinder is also sleeved at the exhaust groove position of the air inlet pipe. An inner sleeve is installed inside the diffuser cylinder. Venting grooves adapted to the exhaust grooves are provided on the inner sleeve. When the venting grooves are aligned with the exhaust grooves, argon can be released to the outside through the diffuser cylinder. When the length of the titanium plate is small and only occupies part of the partition area, the venting grooves can be staggered from the exhaust grooves to avoid the waste of argon and reduce the loss.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] As Figures 1-4 shown, the present application discloses a protection tooling for argon arc welding splicing of titanium plates, including a back channel steel 1. End plates 2 are arranged at both ends of the back channel steel 1. A plurality of partition plates 4 are further installed between the two side walls of the back channel steel 1. The top surface of the partition plate 4 is flush with the top edge of the back channel steel 1. An air inlet pipe 3 is installed through the front and rear end plates 2. Exhaust grooves 31 are arranged in sections on the air inlet pipe 3. A diffuser cylinder 5 is sleeved at the part of the air inlet pipe 3 where the exhaust grooves 31 are provided. The position of the diffuser cylinder 5 is between two adjacent partition plates 4. A plurality of exhaust holes 51 are evenly arranged on the outer surface of the diffuser cylinder 5;

[0023] Specifically, side plates 6 are further connected to the top of both sides of the back channel steel 1. The side plates 6 are inclined from outside to inside. A high-temperature resistant rubber strip 7 is arranged above the side plates 6. The bottom of the side plates 6 is connected to the back channel steel 1 through a rib plate 8, which can facilitate placing the spliced titanium plates on the side plates 6 on both sides. The high-temperature resistant rubber strip 7 arranged on the side plates 6 can keep the relative seal between the titanium plates and the side edges of the back channel steel 1, thereby reducing the leakage of argon gas and fully protecting the weld. The air inlet pipe 3 is provided with exhaust grooves 31 at the positions of adjacent partition plates 4, and a diffuser cylinder 5 is sleeved at this position. The diffuser cylinder 5 can uniformly release argon gas to the surrounding, ensuring that the argon gas uniformly fills the compartment.

[0024] As Figure 3 shown, an inner sleeve 52 is further installed in the diffuser cylinder 5. The inner sleeve 52 is rotationally sleeved on the air inlet pipe 3. Ventilation grooves 53 adapted to the exhaust grooves 31 are arranged on the inner sleeve 52. Both ends of the inner sleeve 52 are installed on the inner wall of the diffuser cylinder 5 through a plurality of connecting plates 54;

[0025] Furthermore, in order to avoid the phenomenon of wasteful empty discharge of argon gas, an inner sleeve 52 is installed in the diffuser cylinder 5. The inner sleeve 52 is sleeved on the air inlet pipe 3. When the ventilation grooves 53 are aligned with the exhaust grooves 31, argon gas can be released to the outside through the diffuser cylinder 5. When the length of the titanium plate is small and only occupies part of the compartment area, the ventilation grooves 53 in this compartment can be staggered from the exhaust grooves 31, thereby avoiding the empty discharge of argon gas and reducing the loss.

[0026] As Figure 1 、 Figure 4As shown in the figure, a support block 41 is also installed on the partition board 4. The support block 41 is slidably arranged in the slot at the center of the top of the partition board 4 and is used to support the spliced titanium plate. The bottom of the partition board 4 is connected with an adjusting rack 42, and an adjusting gear 43 is meshed with the adjusting rack 42. The adjusting gear 43 is rotatably installed on the partition board 4, and a scale line 44 is also arranged on the side of the partition board 4. In addition, in order to stably support the spliced titanium plate, a support block 41 is also arranged at the center of the top of the partition board 4. Under the cooperation of the adjusting gear 43 and the adjusting rack 42, the height of the support block 41 can be adjusted, so as to facilitate the support of the middle joint of the titanium plate, which is relatively stable.

[0027] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt the mature conventional means such as bolts, rivets, and welding in the prior art. The machinery, parts, and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0028] At the same time, the content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.

[0029] The implementation principle of an argon arc welding splicing protection tooling for titanium plates in an embodiment of the present application is as follows:

[0030] During use, the adjusting gear 43 can be rotated first. Through the cooperation of the adjusting gear 43 and the adjusting rack 42, the support block 41 is pushed to slide up and down, and with the cooperation of the scale line 44, the support blocks 41 on multiple partition boards 4 are adjusted to the same height. Then, the spliced titanium plate can be placed on the side plates 6 on both sides of the back channel steel 1, and the weld position of the titanium plate is aligned and placed on the support block 41. Since the high-temperature adhesive strip 7 is arranged on the side plate 6, the relative seal between the titanium plate and the side of the back channel steel 1 can be maintained, thereby reducing the leakage of argon gas and fully protecting the weld. The air inlet pipe 3 is provided with an exhaust groove 31 at the position of the adjacent partition board 4, and a gas diffusing cylinder 5 is also sleeved at this position. The gas diffusing cylinder 5 can uniformly release argon gas to the surrounding, ensuring that the argon gas uniformly fills the compartment;

[0031] In addition, in order to avoid the phenomenon of wasteful empty discharge of argon gas, an inner sleeve 52 is also installed in the gas diffusing cylinder 5. The inner sleeve 52 is sleeved on the air inlet pipe 3. When the air permeating groove 53 is aligned with the exhaust groove 31, the argon gas can be released to the outside through the gas diffusing cylinder 5. When the length of the titanium plate is small and only occupies part of the compartment area, the air permeating groove 53 of this compartment can be staggered from the exhaust groove 31, thereby avoiding the empty discharge of argon gas and reducing the loss.

[0032] The foregoing has shown and described the basic principles, main features and advantages of the present utility model.
