6-dies drawing+five stations precision rolling mills

Production scope: Suitable for rolling copper flat wire with rounded corners. Finished product cross-section: 3-25 mm ² wire R-angle and tolerance: in accordance with the latest version of GB/T 5584 R-angle: 0.5-1mm 1≤b/a≤12 Feed material: Low oxygen copper rod (SCR or equivalent). Finished product size accuracy: Inlet diameter: Φ 3~Φ 8mm, with no oil, dust or dirt on the inlet surface, and no intermediate annealing treatment; Thickness direction: ± 0.005mm; Width direction: ± 0.01mm. Rounding radius: in accordance with GB/T 5584. Acceptance criteria: Feed material: Low oxygen copper rod (SCR or equivalent); Incoming line: wire diameter ≤ Φ 8mm, tensile strength ≤ 250MPa; Line diameter range ≤ 0.01mm; Finished product thickness and dimensional accuracy: ≤± 0.005mm; Surface roughness: ≤ Ra0.8 without bamboo joints Size measurement method: The whole machine runs steadily at the set speed for 5 minutes before rolling for 200 meters, removing 50 meters of tail samples, taking 150 meters of samples, and measuring any size. Wiring quality: The wiring is neat, the gaps are uniform, flat, and there are no defects such as buckling, stacking, or bending. The U-turn wiring is smooth; Note: Acceptance of the status of the I-shaped wheel (based on the inner hole of the I- shaped wheel, radial runout ≤ 1mm, inner side runout ≤ 1mm). Acceptance quantity: Select three typical specifications (to be provided by the customer), with each specification not exceeding 3000Kg. Tensile strength of incoming line: ≤ 250MPa Rolling passes: 5 passes Operating speed: The maximum designed linear speed is 400m/min, and the rolling and drawing processes are determined through negotiation between both parties; Or refer to the production process of Party B in the same industry and similar models. (Party B shall cooperate with Party A to develop production processes and meet Party A's product process requirements)
