2results about How to "Prevent re-oxidation" patented technology

This application relates to the field of welding robots and discloses a tracked mobile welding robot device, including a mobile walking mechanism. A welding execution mechanism is mounted on the mobile walking mechanism, which includes a programmable controllable robotic arm. A welding torch is mounted at the end of the robotic arm. A welding wire feeding mechanism is also mounted on the mobile walking mechanism, comprising a welding wire spool and a welding wire grinding component. The welding wire grinding component includes a sanding sleeve, the inner wall of which is lined with sandpaper. The sandpaper is fitted onto the welding wire and is responsible for grinding the oxide layer on the surface of the welding wire. This invention, through the cyclical, pre-reserved wire pulling and releasing, allows the welding work to proceed in an orderly manner. This ensures that the thickness of the weld wire is the required set thickness and is uniform; it also ensures that the wire feed is continuous and uninterrupted during the welding process; and it saves time waiting for wire grinding.

The utility model discloses an anti-oxidation wiredrawing annealing device based on vacuum sealing, which relates to the technical field of wiredrawing annealing and comprises a wiredrawing device, one side of the wiredrawing device is connected with an annealing box through bolts, one side of the annealing box is fixedly connected with a thermal insulation layer, and one side of the thermal insulation layer far away from the wiredrawing device is fixedly connected with a cooling box. And one side of the cooling box is rotationally connected with a winding table, the side, away from the winding table, of the wire drawing device is rotationally connected with a containing disc, and an air suction hole is formed in the top end of the annealing box. The wiredrawing annealing device based on vacuum sealing oxidation prevention disclosed by the utility model has the advantages that a small amount of oxide generated on the surface of a metal material subjected to wiredrawing operation is cleaned through the cleaning module, and meanwhile, a small amount of generated heat can be absorbed and conducted out of the device through the heat absorption plate and the heat conduction column; the metal material is effectively prevented from being oxidized again, and the wire drawing quality of the metal material is improved, so that the quality of a finished product is improved, and the loss of raw materials is reduced.
