Problems solved by technology

However, in the prior art, there are very few products that use argon arc welding technology to weld 90° arc bending. bending welds, such as figure 1 As shown, the inner edge of the water inlet of the water tank to be welded 100 extends inward to form a square inner recess 101, and the corners of the inner recess 101 are arc-shaped transition connections. The present invention refers to the transition connection structure as a 90° arc shape bend 102, the top weld 103 and the bottom weld 104 of the 90° arc bend 102 need to be welded during production, and if the back gas protection device of the existing argon arc welding welding tool is used, it is through the shielding gas Directly blow the welding place from the outside, so that the material receives a lot of heat during argon arc welding, and the heat dissipation efficiency is insufficient only by direct blowing of the protective gas, and the material is easy to soften and deform, which affects the welding effect

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Such as Figure 2-9 As shown, the argon arc welding tool for 90° arc bending in this embodiment includes a base plate 1 , a base 2 , a support 3 , a top cover 4 , a first pressing mechanism 5 and a second pressing mechanism 6 . Wherein, the middle part of the substrate 1 has an operation opening 11, and the base 2 is arranged on the substrate 1 and is used to support the workpiece 100 to be welded. The opening of the seat 2 is larger than the operation opening 11 on the base plate 1 , and the opening of the base 2 surrounds the operation opening 11 .

[0034]In this embodiment, the support member 3 is arranged on the base 2 and has a support portion 31 for supporting the inner concave portion 101 of the workpiece 100 to be welded. The supporting surface 311 that matches the inner wall of the arc-shaped bend 102. A gas channel 312 ext...

Abstract

The invention relates to a 90° arc bending argon arc welding tool, which comprises a base plate, a base, a support piece and a top cover. The welding tooling of the present invention is provided for welding on 90° arc-shaped bending edges. During welding, argon gas is introduced from the gas channel inlet of the support, and then surrounded by three paths, that is, the first argon gas Spray from the first recessed area on the edge of the upper surface of the top cover to protect the upper edge of the 90° arc-shaped bend top weld, and the second puff of argon is ejected from the second recessed area on the edge of the lower surface of the top cover to 90° The lower edge of the arc-shaped bending top weld is protected, and the third argon gas is ejected from the air outlet of the support surface to protect the entire inner wall of the 90° arc-shaped bend on the workpiece to be welded, thereby expanding the scope of action of the shielding gas , improve the heat dissipation efficiency, and then improve the welding effect.

Description

technical field [0001] The invention relates to a 90° arc bending argon arc welding tool. Background technique [0002] Argon arc welding is a welding technology that uses argon as a shielding gas. Argon arc welding, also known as argon shielded welding, refers to passing argon shielding gas around the arc welding to isolate the air from the welding area to prevent Oxidation of the weld zone. Specifically, argon arc welding technology is based on the principle of ordinary arc welding, using argon to protect the metal welding material, and through high current to melt the welding material into a liquid state on the base material to be welded to form a molten pool, so that the welded material A welding technique in which metal and welding consumables are metallurgically combined. Since argon is continuously supplied during high-temperature fusion welding, the welding consumables cannot be in contact with oxygen in the air, thus preventing the oxidation of the welding consumab...
