Abstract: Disclosed are a lower jacking member, a wire withdrawal method based on the lower jacking member, and a squaring machine including the lower jacking member. The lower jacking member is used for axially fixing a bottom surface of an edge scrap formed by cutting a round rod, and a bottom outline of the edge scrap has a cutting edge. The lower jacking member includes at least two single components, and drive structures independently connected to the single components. A spacing between at least one of the single components and the cutting edge is different from a spacing between the rest of the single components and the cutting edge; and the drive structures are used for driving tops of the single components to abut against the bottom surface of the edge scrap.

Abstract: Disclosed are an upper jacking structure, a half-slitting machine and a half-slitting method. The upper jacking structure includes a lower jacking block, a cutting assembly, a first linear reciprocating device, an upper jacking block and an auxiliary tensioner. The lower jacking block is located below the upper jacking block, a clamping space is formed between the lower jacking block and the upper jacking block, a cutting end of the cutting assembly moves in a vertical direction and a horizontal direction in and out of the clamping space, a movable end of the first linear reciprocating device moves in the vertical direction, and the upper jacking block is provided on the movable end of the first linear reciprocating device; the upper jacking block has a first jacking surface provided with a first jacking head and a second jacking head at either side of a center line of the first jacking surface.
