Embodiment 1
[0013] Take No. 3 copper flat wire as an example:
[0014] 1. Pre-flattening process:
[0015] 1.1 Flattening process:
[0016] φ2.74, tensile 460-490N / mm 2 After the copper round wire is actively paid off by the pay-off frame, it enters the flattening machine and is flattened into a flat wire of 1.49mm×3.45mm.
[0017] 1.2 Drawing process:
[0018] After adjusting the tension, the flattened flat wire enters the 11-die wire drawing machine, and is drawn into a 0.82mm×3.35mm flat wire through 8 dies. The matching die table is die 1: die 2: die 3: die 4: die 5:module 6:module 7:module 8=1.02:1.04:1.06:1.08:1.06:1.04:1.02.
[0019] 2. Annealing process: Send the flat wire produced in the wire drawing process into the annealing machine for online water seal annealing. After the tension control of the annealed flat wire, the wire take-up machine uses the I-shaped wheel to take up the wire into a coil with a weight of 600kg. flat line.

[0023] Take No. 4 copper flat wire as an example:
[0024] 1. Pre-flattening process:
[0025] 1.1 Flattening process:
[0026] φ2.74, tensile 460-490N / mm 2 After the copper round wire is actively paid off by the pay-off frame, it enters the flattening machine and is flattened into a flat wire of 1.38mm×3.80mm.
[0027] 1.2 Drawing process:
[0028] After adjusting the tension, the flattened flat wire enters the 11-die wire drawing machine, and is drawn into a 1.00mm×3.70mm flat wire through 6 dies. The matching die table is die 1: die 2: die 3: die 4: die 5: modulo 6: = 1.02: 1.06: 1.08: 1.06: 1.02.
[0029] 2. Annealing process: Send the flat wire produced in the wire drawing process into the annealing machine for online water seal annealing. After the tension control of the annealed flat wire, the wire take-up machine uses the I-shaped wheel to take up the wire into a coil with a weight of 700kg. flat line.
[0030] 3. Final flattening process: The finished machine pr...
Embodiment 3
[0032] Take No. 5 copper flat wire as an example:
[0033] 1. Pre-flattening process:
[0034] 1.1 Flattening process:
[0035] φ2.74, tensile 460-490N / mm 2 After the copper round wire is actively paid off by the pay-off rack, it enters the flattening machine and is flattened into a flat wire of 1.25mm×4.20mm.
[0036] 1.2 Drawing process:
[0037] After adjusting the tension, the flattened flat wire enters the 11-die wire drawing machine, and is drawn into a 1.00mm×4.10mm flat wire through 4 dies. The matching die table is die 1: die 2: die 3: die 4 = 1.03 : 1.07: 1.05.
[0038] 2. Annealing process: Send the flat wire produced in the wire drawing process into the annealing machine for online water seal annealing. After the tension control of the annealed flat wire, the wire take-up machine uses the I-shaped wheel to take up the wire into a coil with a weight of 800kg. flat line.
[0039] 3. Final flattening process: The finished machine processes the I-wheel take-up in...
