[0030] Example:

[0031] This embodiment shows a high-quality steel wire peeling method, the steps comprising:

[0032] 1) The steel wire passes through the primary peeling die 1 and the secondary peeling die 2 in sequence at a speed of 12m / min-15m / min, and finally passes through the rounding die 3;

[0033] 2) See Figure 1 The primary peeling mold includes a correspondingly arranged previous peeling annular knife body 11 and a next peeling annular knife body 12:

[0034] One side of the last peeling annular knife body 11 corresponds to the horizontal plane, and the other side has a first peeling knife avoidance zone at an angle of 30°-50° with the horizontal plane, so that the steel wire skin can be squeezed into it during peeling to form the last peeling wrinkle to accommodate it;

[0035] One side of the last peeling annular knife body 12 corresponds to the horizontal plane, and the other side has a peeling knife avoidance zone at an angle of 35°-55° with the horizontal plane, so that the steel wire surface can be squeezed into it during peeling to form the wrinkles for the next peeling;

[0036] 3) The secondary peeling mold 2 includes an upper secondary peeling annular knife body 21 and a lower secondary peeling annular knife body 22 which are arranged accordingly:

[0037] One side of the upper secondary peeling annular blade 21 is 10°-15° below the horizontal, and the whole blade is in a 40°-70° fan-shaped shape;

[0038] One side of the lower secondary peeling annular blade 22 is 15°-22° above the horizontal, and the whole blade is in the shape of a fan-shaped blade with an angle of 36°-60°;

[0039] The two sides of the upper secondary peeling annular blade body 21 and the lower secondary peeling annular blade body 22 form a secondary peeling wrinkle accommodating area;

[0040] The wrinkle accommodation area for the last peeling, the wrinkle accommodation area for the next peeling and the wrinkle accommodation area for the second peeling do not overlap at the corresponding positions on the steel wire, and the wrinkles remaining in the first peeling are removed in the second peeling;

[0041] 4) See Figure 4 The full-circle die 3 comprises a group of full-circle annular cutter bodies 31 which are arranged correspondingly to form a full circle.

[0042] The peeling operation is carried out at a temperature of 230°-330°.

[0043] The mold cavity formed by the previous peeling annular knife body and the next peeling annular knife body is larger than the finished steel wire by 0.05-0.06mm.

[0044] The mold cavity corresponding to the upper secondary peeling annular knife body and the lower secondary peeling annular knife body is larger than the finished steel wire by 0.04mm.

[0045] A set of full-circle annular cutter bodies form a corresponding mold cavity to match the specifications of the finished steel wire.

[0046] The upper peeling annular blade body 11, the lower peeling annular blade body 12, the upper secondary peeling annular blade body 21, and the lower secondary peeling annular blade body 22 have a peeling blade body portion 100 with a slope of 12°-15°, see Figure 3 .

[0047] The full-circle annular blade body 31 has a full-circle blade body portion 200 with a slope of 60°-80°, see Figure 5 .

[0048] The full-circle annular blade body 31 is used to remove the residual wire skin after the primary peeling and the secondary peeling, and the full circle is performed through a group of full-circle annular blade bodies 31 in a closed loop.

[0049] Compared with the prior art, the present invention ensures the quality of the steel wire by peeling the surface of the high-quality steel wire, and effectively controls the peeling amount, which is convenient for enterprises to optimize the implementation of product cost control.

[0050] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
