Description

Technical Field

[0001] The utility model relates to a cored wire processing and production technology, in particular to a cored wire straightening device. Background Art

[0002] The cored wire is made of alloy powder wrapped by a strip-shaped steel strip. According to the different alloy powders, it can be divided into: silicon calcium cored wire, silicon manganese calcium wire, silicon calcium barium wire, barium aluminum wire, aluminum calcium wire, calcium iron wire, pure calcium wire, etc. After the aluminum titanium iron alloy comes out of the cored wire machine, problems such as bending, bending and right angles will occur, which will affect the progress and production of subsequent processes, so this part of the cored wire needs to be straightened. For example, a Chinese patent with publication number CN206127351U discloses a cored wire straightening device, comprising a frame, a vertical straightening wheel group, and a horizontal straightening wheel group; the vertical straightening wheel group and the horizontal straightening wheel group are arranged inside the frame; it is characterized in that the cored wire is placed in a straight line at the middle position of the vertical straightening wheel group and the horizontal straightening wheel group, and the vertical straightening wheel group and the horizontal straightening wheel group are spatially perpendicular to each other. During the feeding process of the cored wire, the device is used to straighten the wire in both horizontal and vertical directions, limiting the freedom of the cored wire. After passing through the wire feeding guide tube, the cored wire enters the molten steel in a straight line, completely avoiding the cored wire from entering the molten steel in a spiral line, feeding the cored wire to the expected molten steel depth, improving the accuracy of wire feeding, and greatly improving the utilization rate of the fed cored wire.

[0003] However, the distance between the upper and lower vertical straightening wheels is fixed, which cannot meet the straightening requirements of cored wires of different sizes, and has limitations in use and poor practicality. To this end, a Chinese patent with publication number CN218425311U discloses a cored wire straightening device, in the field of cored wire straightening technology, specifically a cored wire straightening device, comprising: a base, a movable groove is provided inside the base, a sliding groove is provided on the top surface of the base, a cored wire body is provided on the top surface of the base, a straightening structure is installed inside the base, and the straightening structure includes a threaded hand rod, the threaded hand rod is movably installed inside the movable groove through a bearing, the outer side of the threaded hand rod is threadedly connected with two groups of threaded sleeve rods, and sliders are fixedly welded at both ends of the threaded sleeve rod.

[0004] This patent provides movable straightening rollers to adapt to the straightening of cored wires of different sizes. However, during the straightening process, the freedom of the cored wire can only be limited within one plane, resulting in poor straightening effect of the cored wire, which affects the subsequent processing of the cored wire.
