wherein, the fixed clip 200 is provided with a first V-shaped plate 210, and the movable clip 300 is provided with a second V-shaped plate 310; the openings of the first chevron 210 are opposite the openings of the second chevron 310, and the area between them is the sample placement area.
During operation, a plurality of processed round rods are placed in the sample placing area like steel pipe stacking, the movable clamp 300 is moved to enable the second V-shaped plate 310 to be close to the first V-shaped plate 210, the sample placing area is gradually reduced, a plurality of round rods are clamped tightly, then the movable clamp 300 is locked with the channel 110, finally the wire cutting machine is started to move the molybdenum wires to perform material breaking operation on the round rods, and redundant materials at two ends of the round rods are cut off respectively. The area is placed through the sample between first V template 210 and the second V template 310 promptly, but many round bars of disposable clamping can accomplish the disconnected material operation at many round bar both ends simultaneously, has improved disconnected material machining efficiency greatly.
In order to improve the stability of the round bar in the process of material breaking after being clamped, two first V-shaped plates 210 are symmetrically arranged and are respectively positioned on the bases 100 on the two sides above the channel 110; the two first V-shaped plates 210 are connected through a bottom plate 220 to form a U-shaped passageway; the second chevron 310 is located directly above the channel 110 and is movable into the U-shaped aisle. That is, by the movement of the movable clamp 300, the second V-shaped plate 310 is overlapped with the first V-shaped plate 210 in a crossing manner, and is contacted with the round bar from three positions respectively, so as to form three-point positioning, thereby clamping the round bar.
