Problems solved by technology

Submerged arc welding flux automatic recovery suction nozzle is usually the suction nozzle (such as figure 1 ) into a vertical installation, the suction nozzle is in the working state of being dragged forward along with the welding torch during work, when the working state encounters a bump or an obstacle, because the suction nozzle is connected with the recovery rubber hose, the flexibility of the hose can make the suction The nozzle can climb over protrusions or obstacles. If the nozzle is required to move forward with the welding torch, that is, the nozzle is installed tilted backward but it is easy to get stuck when it moves forward, and then mechanical failure occurs.

Embodiment Construction

[0014] In order to describe the present invention more specifically, the present invention will be further described below in conjunction with the accompanying drawings, but the implementation of the present invention is not limited to this embodiment.

[0015] combine figure 2 It can be seen that the front end of the suction nozzle of the present invention is leaning forward. When encountering a protrusion or an obstacle, the flexibility of the hose can make the suction nozzle climb up the protrusion or obstacle and then cross the obstacle. It is in the shape of a bridge arch and imitates the shape of the weld seam to ensure that the useful flux can be recovered as much as possible without touching the weld seam. The suction port is arranged in the middle and rear of the bridge arch. The suction pipe can be connected to the flux rubber hose at a certain angle behind ( Such as figure 2 ).

[0016] This nozzle is especially suitable for installation at the end of the cross ...

Abstract

The invention relates to a soldering flux suction nozzle, wherein the front end of the suction nozzle is in a forward leaning way, a rear middle part is in a bridge arch way and in a copy welding line way, the suction nozzle is arranged in the bridge arch type rear middle part, the suction pipe is backwards formed at a certain angle and is connected with a flux hose. The flux hose is a rubber hose. The suction nozzle is arranged at a cross arm end of a welding manipulator. The flux suction nozzle can effectively pass over either bulges or barriers; and the soldering flux suction nozzle is good in flux recovery effect, convenient to use and strong in practicality.

Description

technical field [0001] The invention relates to a flux recovery suction nozzle, in particular to a flux recovery suction nozzle used in submerged arc welding. Background technique [0002] Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) is a method in which the arc burns under the flux layer for welding. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke make it the main welding method in the manufacture of important steel structures such as pressure vessels, pipe section manufacturing, and box-shaped beams and columns. [0003] During welding, the welding machine moves forward, and the welding arc moves with it. The arc continuously melts the weld metal, welding wire and flux in front, while the edge behind the molten pool begins to cool and solidify to form a weld, and the liquid slag then condenses to form a hard slag crust. Unmelted flux can be recycled by the flux r...
