Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and specifically to a base welding local cooling welding device. Background Art

[0002] In the fields of mechanical manufacturing and steel structure processing, as the basic support structure of equipment or components, the welding quality of the base directly affects the stability and safety of the overall structure. Base welding often involves continuous welding operations of long welds and multiple joints. During the welding process, the high heat generated by the arc or heat source will cause the temperature in the local area to rise sharply, forming a significant temperature gradient, which will in turn cause problems such as welding deformation, grain coarsening, and stress concentration. The existing cooling methods mostly use natural cooling and forced air cooling.

[0003] However, in the actual base welding process, the divergent air flow of the traditional air cooling device is difficult to effectively suppress the heat input of long-distance welding. Especially when the base size is large, the air flow is blocked on the surface of the base, resulting in the boundary layer separation phenomenon, and a large amount of cooling air flow is dissipated before acting on the target area. At the same time, due to the inconsistent base size specifications, the existing clamping and positioning devices lack the ability of adaptive adjustment.

[0004] The above problems make it difficult for the existing technology to meet the quality requirements of high-precision base welding, and there is an urgent need for a base welding local cooling welding device. Summary of the Invention

[0063] Embodiment Three

[0064] To achieve the functions of reducing the diffusion of the air-cooled airflow and precise cooling, as Figure 1 、 Figure 2 and Figure 5 shown, in this embodiment, a first connecting frame 41 and a second connecting frame 42 are fixedly installed at the bottom of the air deflector 4. The first connecting frame 41 and the second connecting frame 42 are used to fix the installation position of the air deflector 4, and the first connecting frame 41 and the second connecting frame 42 are respectively fixedly installed with the placement box 113 and the slag receiving box 112.

They are respectively fixedly installed with the placement box 113 and the slag receiving box 112, having the characteristic of ensuring the stability of the air deflector 4.

[0066] Furthermore, a air supply mechanism 7 is further included. The air supply mechanism 7 is fixedly installed on the back of the operation table 1, and the air outlet direction of the air supply mechanism 7 matches the position where the air inlet slot 43 is opened.

[0067] Specifically, the air supply mechanism 7 is fixedly installed on the back of the operation table 1 to realize the function of providing cooling air flow for the welding device. Its air outlet direction matches the opening position of the air inlet groove 43, and it has the characteristic of enabling the cooling air flow to accurately enter the flow guiding cover 4. The air supply mechanism 7 adopts a design corresponding to the position of the air inlet groove 43 to ensure that the air flow effectively acts on the welding area.

[0068] The air inlet grooves 43 are evenly distributed along the semi-circular structure of the flow guiding cover 4, which can ensure that the cooling air flow can evenly enter the flow guiding cover 4 to cool the welding area. When the air enters the flow guiding cover 4 from the air inlet grooves 43, it will first contact the base being welded, then bounce back, and then under the guiding action of the flow guiding cover 4, it can make the air fully contact the base, and the air cooling acts on the back of the welding surface, thereby effectively improving the cooling effect.

[0069] When the present invention is in use, the operation table 1 is pushed, and the device is moved to a suitable working position by the universal wheels 111 at the bottom of the chassis 11, and then fixed by the braking device on the universal wheels 111 to ensure that the device is stable and does not move.

[0070] According to the size of the base to be welded, first adjust the angle of the adjusting mechanism 2. The positioning pin 121 on the first column 12 is inserted into the first positioning hole 231 or the second positioning hole 233 on the mounting frame 23, and the adjusting mechanism 2 is rotated to a suitable angle and locked by cooperating with the rotation of the first rotating shaft 122. Then, the adjusting cylinder 22 is started to drive the second positioning plate 5 to move and clamp the base together with the first positioning plate 3. The anti-slip sleeves 6 on both of them can prevent the base from sliding.

[0071] The air supply mechanism 7 installed on the back of the operation table 1 is started, and the cooling air flow enters the flow guiding cover 4 along the air outlet direction matching the air inlet groove 43. The semi-circular structure of the flow guiding cover 4 reduces the air flow diffusion. After the air enters through the air inlet groove 43, it contacts the back of the welding surface of the base, bounces back, and then fully contacts the base under the guiding of the flow guiding cover 4 to achieve effective temperature reduction.

[0072] After confirming that the base is firmly clamped and the cooling system is operating normally, the base is welded. The welding slag generated during the welding process falls into the slag receiving box 112, which is convenient for subsequent cleaning.
