Width of corrugation: 300~1300mm 2. Thickness of steel sheet: 0.5-1.75mm 3. Length of formed sheet: >=290mm 4. Height of corrugation: 50-400mm 5. Corrugation pitch: >=40mm 6. Corrugation pitch accuracy: ±0.25mm                     7. Corrugation inner gap: 6mm 8. Max. Pressure: 25MPa 9. Max. Flux: 200L/minIII  Equipment Description 1. Description of Necessary Machine Unit           (1) Hydraulic Automatic Decoiler Machine   1.1 Introduction   The base frame of decoiler is welded steel construction, the expandable mandrel is mounted on roller bearings. Expansion and retraction of the mandrel is hydraulically realized.When the steel sheet is automatically fed, a hydraulic motor equipped on the mandrel will function as an auxiliary mechanism for decoiling and partially rewinding the coil. A photoelectrical device composed of 2 photoelectrical switches can sense the sheet hanging between decoiler and corrugation former to control material feeding process.    1.2 Parameters of Our Hydraulic Automatic Decoiler Machine  1) Hydraulic pressure: 16MPa        2) Coil inner diameter: Min 470mm, Max 520mm  3) Max. External diameter of steel coil: 1200mm  4) Coil width: Max. 1300mm  5) Coil weight: Max. 10 tons(with inclined support structure)      1.3 Pictures of Our Hydraulic Automatic Decoiler Machine     (2) Transformer Corrugated Fin Forming Machine 2.1 Introduction  The corrugation former consists of steel-welded base, 2-roll feeder, movable forming mold, movable forming pressboard and fixed forming pressboard. It is employed to form the steel corrugation automatically. The corrugation former processed steel sheet using the theory of corrugation extrusion, it is controlled by high accuracy servo system. Hydraulic oil is supplied by hydraulic station. The control system of the former is independent from that of the welding unit. There are 2 quenched pressing bars on both movable forming pressboard and fixed forming pressboard, which are used to press the two ends of corrugation. The position of pressing bars is adjustable according to the width of steel sheet. Reinforcement slots(embossments) can be formed upon customer's request. Main Technical Parameters of Transformer Corrugated Fin Production Line 1.
