Description

Technical Field

[0001] This utility model relates to the field of welding, and more specifically, it relates to a splash-proof device for tank welding. Background Technology

[0002] In the process of tank welding, especially for high-pressure and high-requirement storage tanks made of metal, welding technology is particularly important. Stainless steel tanks are widely used in many fields due to their excellent pressure resistance and corrosion resistance.

[0003] In the manufacturing of this can, the upper and lower parts of the can are first produced, and then the two parts are welded together. For this type of small can, laser welding is usually used to weld the joint. When the laser welding machine welds the can, because the can is heated at a high temperature, a small amount of molten metal droplets will form on the metal part of the can. If the splashed molten metal droplets adhere to and cool on the weld or the surface of the can, they will form raised particles on the surface of the can after cooling, which will affect the smoothness of the surface of the can. The finished can will also have the effect of being sharp to the touch and packaging due to the presence of metal particles.

[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a splash-proof device for tank welding.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: It includes a shell and a tank. A base is fixedly connected to the bottom surface of the shell. Fixed concave plates are fixedly connected to the two inner side walls of the shell. Semi-circular through grooves are opened on the opposite surfaces of the two fixed concave plates. A turntable is rotatably connected to the base between the two fixed concave plates. The bottom surface of the tank abuts against the top surface of the turntable. A welding plate is installed at the top of the base. A welding head is installed on the top surface of the welding plate. An upper baffle and a lower baffle are installed on the shell facing the welding plate. An inclined baffle is fixedly connected to the bottom surface of the upper baffle and to the top surface of the lower baffle. A through hole is opened at the center of the inclined baffle.

[0007] By adopting the above technical solution, this device performs welding work by placing an upper and lower tank inside the shell. The tank above the turntable is fixed by a fixed concave plate fixedly connected to the two inner walls of the shell. The tank rotates at the top of the turntable, and the rotating tank is welded by a welding head installed above the welding plate. When the welding head welds the tank, molten metal splashes and affects the tank. Therefore, an upper baffle and a lower baffle are installed on the surface of the tank. The upper and lower baffles protect the surface of the upper and lower halves of the tank. An inclined baffle is fixedly connected to the lower part of the upper baffle and the upper part of the lower baffle. A through hole is opened in the center of the inclined baffle, so that the welding head can enter the tank and weld the joint of the tank. Due to the large shielding area of ​​the baffle, the surface quality of the tank is reduced by the splashed molten metal.

[0008] The present invention is further configured such that: a number of fixing nails are installed at the connection between the upper baffle and the lower baffle and the shell.

[0009] By adopting the above technical solution, the upper baffle and the lower baffle are connected to the shell by a number of fixing nails. The upper baffle and the lower baffle can be fixed by using fixing nails.

[0010] The present invention is further configured such that the upper baffle and the lower baffle are semi-cylindrical.

[0011] By adopting the above technical solution, the semi-cylindrical upper and lower baffles can better fit the surface of the tank, reducing the possibility of splashed molten metal entering the baffles and the tank.

[0012] The present invention is further configured such that a spherical groove is formed at the top of the turntable.

[0013] By adopting the above technical solution, the top of the turntable is a spherical groove, and the upper and lower ends of the tank are composed of two metal circular plates. Therefore, the upper and lower surfaces of the tank are spherical, so that the tank fits into the turntable.

[0014] The present invention is further configured such that: a sliding groove is provided at the top of the base, and an insert is fixedly connected to the bottom of the welding plate, and the welding plate is slidably connected to the sliding groove of the base through the insert.

[0015] By adopting the above technical solution, the welding plate can slide and move through the bottom block and the groove opened in the base, thereby controlling whether to perform welding work on the tank body.

[0016] The present invention is further configured such that the welding head is connected to the welding plate via a fixing ring installed above.

[0017] By adopting the above technical solution, the welding head is connected to the welding plate above the welding plate through a fixing ring, which not only better stabilizes the welding head and fixes it, but also makes it easy to disassemble.

[0018] In summary, this utility model has the following beneficial effects: by setting up upper and lower baffles, when the welding head is welding the tank, the upper and lower baffles protect the upper and lower parts of the tank, respectively. The welding head is directly facing the through hole located between the upper and lower baffles and opened on the inclined baffle to weld the connection position of the tank, thereby reducing the splashing of molten metal.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example:

[0025] Anti-splash device for tank welding, such as Figure 1 , Figure 4 As shown, the device includes a shell 1 and a tank 3. A base 11 is fixedly connected to the bottom surface of the shell 1. Fixed concave plates 12 are fixedly connected to the two inner side walls of the shell 1. Semi-circular through slots are opened on the opposite surfaces of the two fixed concave plates 12. A turntable 13 is rotatably connected to the base 11 between the two fixed concave plates 12. The bottom surface of the tank 3 abuts against the top surface of the turntable 13. An electric welding plate 2 is installed at the top of the base 11. An electric welding head 21 is installed on the top surface of the electric welding plate 2. An upper baffle 41 and a lower baffle 42 are installed on the shell 1 facing the electric welding plate 2. An inclined baffle 44 is fixedly connected to the bottom surface of the upper baffle 41. An inclined baffle 44 is fixedly connected to the top surface of the lower baffle 42. A through hole is opened at the center of the inclined baffle 44.

[0026] like Figure 2As shown, several fixing nails 43 are installed at the connection between the upper baffle 41 and the lower baffle 42 and the housing 1. The upper baffle 41 and the lower baffle 42 are semi-cylindrical.

[0027] like Figure 3 As shown, the top of the turntable 13 has a spherical groove, the top of the base 11 has a sliding groove 111, the bottom of the welding plate 2 is fixedly connected to the insert 23, the welding plate 2 is slidably connected to the sliding groove 111 of the base 11 through the insert 23, and the welding head 21 is connected to the welding plate 2 through the fixing ring 22 installed above.

[0028] This device performs welding on a tank 3 consisting of two parts, upper and lower, placed inside a housing 1. First, the tank 3 is placed above a turntable 13. The top of the turntable 13 is a spherical concave groove. The upper and lower ends of the tank 3 are composed of two metal circular plates, making both the upper and lower surfaces of the tank 3 spherical, allowing the tank 3 to fit into the turntable 13. A fixing plate 12, fixedly connected to the two inner walls of the housing 1, secures the tank 3 above the turntable 13. The tank 3 rotates on the top of the turntable 13. The rotating tank 3 is welded by a welding head 21 mounted above a welding plate 2. When the welding head 21 welds the tank 3, molten metal splashes, affecting the tank 3. Therefore, an upper baffle 41 and a lower baffle 42 are installed on the surface of the tank 3. The upper baffle... 41 and the lower baffle 42 are connected to the shell 1 by several fixing nails 43. The upper baffle 41 and the lower baffle 42 are set as semi-cylindrical. The semi-cylindrical upper baffle 41 and the lower baffle 42 can better fit the surface of the tank 3, reducing the situation where splashed molten metal enters the baffle and the tank 3. The upper baffle 41 and the lower baffle 42 protect the surface of the upper and lower parts of the tank 3. An inclined baffle 44 is fixedly connected to the lower part of the upper baffle 41 and the upper part of the lower baffle 42. A through hole is opened at the center of the inclined baffle 44 for the welding head 21 to extend into the tank 3 and weld the connection of the tank 3. Due to the large shielding area of ​​the baffle, the surface quality of the tank 3 is reduced by splashed molten metal.

[0029] The welding plate 2 moves by sliding through the bottom insert 23 and the groove 111 opened in the base 11, thereby controlling whether to weld the tank body 3. The welding head 21 is connected above the welding plate 2 by the fixing ring 22, which not only better stabilizes the welding head 21 and fixes it, but also makes it easy to disassemble.
