Embodiment 1
[0025] A kind of sharpening process that is beneficial to steel wire drawing and piercing die in embodiment one is made up of following steps:
[0026] A. Pay-off and straightening: Unfold a wire rod with a diameter of 15.5mm for pay-off. The unrolled steel wire 1 runs horizontally and horizontally between the upper and lower rows of straightening rollers 2-1 of the rotary straightener 2. During the process, the steel wire 1 is corrected into a straight strip (to facilitate subsequent threading);
[0027] B. Press the steel wire: the straightened steel wire 1 passes through the threading hole Ⅰ3-2 in the fixed chuck 3, the inner cavity of the electromagnetic induction heating tube 4 with a length of 800mm, and the wire hole Ⅱ5 in the moving chuck 5 -2, turn off the rotary straightener 2 at this time; then screw down the pressing bolt Ⅰ3-1 in the fixed chuck 3 and the pressing bolt Ⅱ5-1 in the moving chuck 5 respectively, so that the pressing bolt Ⅰ3- 1 and the lower end of th...
Embodiment 2
[0032] A kind of sharpening process that is beneficial to steel wire drawing and piercing die among the embodiment two is made up of following steps:
[0033] A. Pay-off and straightening: Unfold the wire rod with a diameter of 5.5mm for pay-off, and the unrolled steel wire 1 runs horizontally and horizontally between the upper and lower rows of straightening rollers 2-1 of the rotary straightener 2. During the process, the steel wire 1 is corrected into a straight strip (to facilitate subsequent threading);
[0034] B. Press the steel wire: the straightened steel wire 1 passes through the threading hole Ⅰ3-2 in the fixed chuck 3, the inner cavity of the electromagnetic induction heating tube 4 with a length of 300mm, and the wire hole Ⅱ5 in the moving chuck 5 -2, turn off the rotary straightener 2 at this time; then screw down the pressing bolt Ⅰ3-1 in the fixed chuck 3 and the pressing bolt Ⅱ5-1 in the moving chuck 5 respectively, so that the pressing bolt Ⅰ3- 1 and the low...
Embodiment 3
[0039] A kind of sharpening process that is beneficial to steel wire drawing and piercing die among the embodiment three is made up of following steps:
[0040] A. Pay-off and straightening: Unfold a wire rod with a diameter of 10.5mm for pay-off, and the unrolled steel wire 1 runs horizontally and horizontally between the upper and lower rows of straightening rollers 2-1 of the rotary straightener 2, During the process, the steel wire 1 is corrected into a straight strip (to facilitate subsequent threading);
[0041] B. Press the steel wire: the straightened steel wire 1 passes through the threading hole Ⅰ3-2 in the fixed chuck 3, the inner cavity of the electromagnetic induction heating tube 4 with a length of 600mm, and the wire hole Ⅱ5 in the moving chuck 5 -2, turn off the rotary straightener 2 at this time; then screw down the pressing bolt Ⅰ3-1 in the fixed chuck 3 and the pressing bolt Ⅱ5-1 in the moving chuck 5 respectively, so that the pressing bolt Ⅰ3- 1 and the lo...
