Detailed Embodiment
[0023] Please refer to the attached drawings of the specification Figure 1 to attached drawing Figure 6 As shown, the present invention is a submerged arc welding head device for a box body, including a frame ( Figure 2 ), a welding torch device ( Figure 3 ), a Y-shaped positioning and navigation device ( Figure 4 ), a flux baffle device ( Figure 5 ), and a flux recovery pipe.
[0024] As Figure 1 shown, it is a schematic diagram of the overall structure of a submerged arc welding head device for a box body.
[0025] As Figure 2 shown, among them, the first plate 21, the second plate 22 and the third plate 23 are welded to form a "C"-shaped frame.
[0026] As Figure 3As shown, the conductive rod 1 31 and the conductive rod 2 32 are used to adjust the welding angle through the pole 1 angle adjuster 33 and the pole 2 angle adjuster 34. In this embodiment, the pole 1 position adjustment device 37 and the pole 2 position adjustment device 38 are respectively installed on the plate 2 22 and the plate 3 23 by bolt connection, so that the welding wire can be adjusted up and down and left and right. The pole 1 angle adjuster 33 and the pole 2 angle adjuster 34 are respectively installed on the pole 1 position adjustment device 37 and the pole 2 position adjustment device 38. The front welding wire 39 and the rear welding wire 40 are respectively extended through the conductive rod 1 31 and the conductive rod 2 32 for positioning and welding. The flux tube 35 is fixed on the conductive rod 1 31 through the connector 36. The above components constitute a welding gun device.
[0027] Further explanation, such as Figure 4 As shown, the Y-type electronic sensing contact 41 is connected to the electronic feedback device 42 through bolts, and the angle is adjusted through the Y-type positioning rotation connection device 43, and the position is adjusted through the bent round rod 44, the straight round rod 45, and the Y-type positioning position adjustment device 46. The Y-type positioning position adjustment device 46 is driven by a cylinder and finally fixed with the plate 47 and the plate 22 by bolts. The above components constitute a Y-type positioning navigation device.
[0028] Further explanation, such as Figure 5 As shown, the baffle 51 is fixed with bolts by angle steel adjusters 52 and 53, extended and retracted up and down by telescopic devices 54 and 55, adjusted up and down and left and right by baffle position adjusting devices 56 and 57, and fixed to the frame by bolts by baffle position adjusting devices 56 and 57. The above components constitute a flux baffle device.
[0029] To further explain, the flux recovery pipe 61 is connected and fixed to the frame by welding through the plate 62, and a box-type submerged arc welding head device is formed through the connection of the above-mentioned various parts.
[0030] The working principle of a box submerged arc welding head device of the present invention is as follows: First, through the rough positioning of the entire device, the Y-type electronic sensing contact 41 is brought close to the edge of the box, and pressure is applied to the Y-type electronic sensing contact 41 through the Y-type positioning position adjustment device 46 to make the Y-type electronic sensing contact 41 close to the edge of the box. During the welding crane project, the electronic feedback device 42 continuously gives system signal feedback to prevent the Y-type electronic sensing contact 41 from deviating from the edge of the box.
[0031] The specific operation steps are as follows: before welding, the Y-shaped electronic induction contact 41 is positioned first, and then the front welding wire 39 and the rear welding wire 40 are positioned, mainly through the pole one angle adjuster 33 and the pole two angle adjuster 34, and then the pole one position adjustment device 37 and the pole two position adjustment device 38 are respectively used to make the welding wire at the accurate position of the groove.
[0032] The baffle 51 is further adjusted through the baffle position adjusting device 56 and the baffle position adjusting device 57 so that the baffle 51 is located above the edge of the box body to prevent the flux and molten iron from leaking out during welding.
[0033] The above specific implementation methods are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
