Overall operation of decoiler

　　Overall operation of decoiler

　　A rotating oil cylinder is connected to the tail end of the reel shaft, and the piston rod of the oil cylinder drives the front-end quadrangular shaft to slide axially through a pull rod in the center of the reel shaft, thereby driving the sector plate to expand and contract radially. The frame of the decoiler can be moved on the guide rail of the machine base and driven by a hydraulic cylinder, which can realize the central position control. The standard configuration consists of: hydraulic loading trolley, uncoiler, hydraulic feeder, clamping and initial leveling machine, transition table, correction mechanism, fine-tuning unit, shearing machine, conveying table, pneumatic discharge rack, stacking trolley, Hydraulic system, electrical control system, etc. At the same time, it can be equipped with trimming machine, slitting machine, side wire winding machine and other mechanisms according to user needs to obtain four trimming plates or slitting and cutting the steel plate along the length direction. The roll material of the automatic hydraulic decoiler rolls freely on the flow shaft seat of the left and right boxes to open the roll material. The steel plate advances to the decoiler on the conveyor frame, which is the front process of the decoiler. The operator needs to rise or fall (hydraulic jack), adjust the steel coil material to the center of the expansion and contraction reel shaft (that is: the material can enter the expansion and contraction shaft), and adjust the movable bearing seat at the top of the decoiler to make it match the decoiler Keep it on the same level. Adjust the expansion nut to make the four bow-shaped plates and expand the steel coil material to avoid deformation and damage of the steel coil material during work.

　　After the steel coil material is swollen tightly, manually bounce the uncoiler to observe whether the material can move freely to avoid various hidden dangers during work. In order to enhance the stability of the reel, a support arm device is designed on the head of the reel. When there is a steel coil on the reel, the support arm is driven by an oil cylinder to support the head of the reel. Affect the coiling. The leveling line is suitable for uncoiling, leveling and shearing of cold-rolled, hot-rolled steel coils, low-alloy coils, etc., into various specifications of cut-to-length plates with medium thickness. Suitable for machinery, vehicles, metal products, household appliances, steel structures, decoration and other industries. Any violation of the decoiler's safety operating procedures and cause mechanical damage shall be punished in strict accordance with the company's relevant system. The main components of the hydraulic system of the production line adopt high-precision components, and the electrical control adopts imported PLC program controller and touch screen for full-line functional control. It has the characteristics of high automation, good leveling quality, high cutting precision, stable and reliable performance, and convenient operation and maintenance. , One-time loading of coil material can realize the smooth completion of each process, effectively reduce the labor intensity of workers, and has a high cost performance. It is a high-performance product integrating machinery, electricity and hydraulics. Uncoilers must strictly follow the "Uncoiler Operating Regulations" to operate. During the loading operation, a dedicated person must cooperate with the forklift driver to make the steel coil material basically consistent with the center of the expansion and contraction reel shaft, and then the forklift driver slowly puts the steel coil material on the trolley.

　　The mandrel of the uncoiler is connected to four sector-shaped plates through the sloped dovetail slots on the four end faces. Each sector-shaped plate is prevented from moving in the axial direction through a radial slide at the end, but can expand and contract in the radial direction. The automatic hydraulic automatic decoiler is a special equipment for sheet metal leveling. It can be used for leveling line steel plates and uneven plates according to the relevant configuration
