Embodiment 1
[0020] Example 1: see image 3 , 4 , the coaxial cable metal strip outer conductor longitudinal wrap molding die of the present invention is composed of two symmetrical 7-character bar-shaped upper dies 1 and two symmetrically combined (combined stitching lines are omitted in the perspective view) similar U-shaped lower dies 2. The short vertical side of the 7-shaped mold is processed with an inwardly protruding arc approximately equal to the radius of the formed tube, and the upper part of the two upright sides of the lower mold has an inner concave arc that matches the shape, and the combination of concave and convex forms a slit arc for deformation. Groove 3, lower mold U-shaped bottom edge is flat bottom 4, and the bottom edge width gradually shrinks according to the mold axial direction, and the length is to make the arc-shaped wrap angle on both sides of the flat metal strip become an arc of 75-100°. When the cable is longitudinally wrapped with metal tape, the metal ta...
Embodiment 2
[0021] Example 2: see Figure 5 , 6 , as mentioned above, wherein the U-shaped bottom of the lower mold is a gradually shrinking arc 5 .
[0022] According to the concept of the present invention, the upper mold of the mold of the present invention can also adopt a two-piece integral structure, or the mold can be formed into an integral structure by milling.
