Monofilament is spent, then is sent by finished product diaphragm capsule to wrap-up.Further, first direction can be counter clockwise direction, volume fixing turn
It can be 2 to 4 circles, can so guarantee that Extra High Strength monofilament stable winding on the first cone pulley 1 or the second cone pulley 2, does not occur
Slip phenomenon.
In practical applications, it is 0.33mm that the steel wire drawing specification that specification is 1.94mm, phosphorus content is 0.97%, which can be used,
Extra High Strength monofilament, using 22 passage water tanks carry out drawing, can take n be 3, i.e., the 1st passage to the 19th passage use first
Group the 5, the 20th passage of mold, the 21st passage and the 22nd passage use second group of mold 6.The steel wire or high-strength that each passage pulls out
The string diameter of degree monofilament is shown in Table 1, and the unit of string diameter is mm.
1 1.94-0.33 template strand of table
| Passage | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |

4, the compression ratio distribution of the 20th passage, the 21st passage and the 22nd passage before increasing third group mold 4 is shown in Table 2, increases third group
The 20th passage, the corresponding passage of the first drawing mould 41, the 21st passage, the corresponding passage of the second drawing mould 42 after mold 4
Compression ratio distribution with the 22nd passage is shown in Table 3, and the sizing bandwidth of the first drawing mould 41 is 0.355mm, the second drawing mould
42 sizing bandwidth is 0.336mm, and the unit of string diameter is mm.
Table 2 increases the compression ratio distribution before third group mold
| Passage | 20 | 21 | 22 |
| String diameter | 0.368 | 0.343 | 0.330 |
| Compression ratio | 13.13% | 7.44% |
Table 3 increases the compression ratio distribution after third group mold
| Passage | 20 | The corresponding passage of first drawing mould | 21 | The corresponding passage of second drawing mould | 22 |
| String diameter | 0.368 | 0.355 | 0.343 | 0.336 | 0.330 |
| Compression ratio | 6.94% | 6.64% | 4.04% | 3.54% |
13.13% compression ratio between contrast table 2 and the 3, the 20th passage of table and the 21st passage is corresponding by the first drawing mould 41
Passage is divided into 6.94% and 6.64%, and 7.44% compression ratio between the 21st passage and the 22nd passage is divided by the second drawing mould 42
