Embodiment 1
[0031] Such as Figure 1A , Figure 1B with Figure 1C As shown, it is a structural schematic diagram, a front view and a side view of Embodiment 1 of the thin metal wire pulling and clamping head of the present invention; wherein, the thin metal wire pulling and clamping head includes: pulling and clamping head 1, clamping member 11, cutting seam 12, thin wire 2 and weld 3.
[0032] The two clamping parts 11 are square, and they can be cut into the same two halves by a square part along the central axis. The cutting method is wire cutting, and the two half surfaces of the cutting are flat; The same two square pieces. The rounded corners of the edges of the square piece and the rounded corners of the plane slits at both ends reduce the stress concentration of the thin metal wire at the end of the traction and clamping head, and at the same time reduce the accuracy requirements of the drawing direction during traction and clamping, and increase the service life.

Embodiment 2
[0037] Such as Figure 2A , Figure 2B with Figure 2C As shown, it is a schematic structural view, a front view and a side view of Embodiment 2 of the thin metal wire pulling and clamping head of the present invention; wherein, the thin metal wire pulling and clamping head includes: a pulling and clamping head 1, a clamping member 11, a cutting seam 12, thin wire 2 and weld 3.
[0038] The thin wire 2 is a wire with a very small diameter, which can be a thin wire that is easy to weld; it can also be a thin wire that is refractory and difficult to weld, such as tungsten wire, molybdenum wire or other alloy wire.
[0039] The welding of the two clamping parts 11 is argon arc welding, and the slit 12 is welded by argon arc welding to form two side welds 3 to connect the two clamping parts 11 together. The shrinkage stress is clamped by the two halves of the clamping head, the shrinkage stress of the weld is large, the clamping and fixing are reliable, and the thin metal wire ...
Embodiment 3
[0044] Such as image 3 As shown, it is a structural schematic diagram of the third embodiment of the thin metal wire pulling and clamping head of the present invention; wherein, the thin metal wire pulling and clamping head includes: pulling and clamping head 1, clamping member 11, slit 12, thin metal wire 2 and weld 3.
[0045] Both clamping pieces 11 are hemispherical, and they can be cut into the same two halves by a spherical piece along the central axis, and a plane is cut on one side of the spherical piece, and the cutting method is wire cutting, cutting The surfaces of the two halves are flat; they can also be two hemispheres with the same shape and size. The rounded corners of the hemispherical edges and the rounded corners of the plane slits at both ends reduce the stress concentration of the thin metal wire at the end of the traction and clamping head, and at the same time reduce the accuracy requirements of the drawing direction during traction and clamping, and i...
