Working process of the present utility model is:
According to the design information that twines pre-stress die, determine to twine and use steel coil strip.Select the high-strength spring steel, thickness of strips is less than 0.2mm, and width determines that according to the actual axial length that is wound mould total length should satisfy the material usage that twines a secondary mould.Before the equipment energising, steel coil strip is placed on the mandrel of uncoiling mechanism 1, steel coil strip can freely be rotated around the axis of mandrel.By hand steel band is launched, pass track adjusting wheel, the straightener roll group of smoothing mechanism 2 successively, the tension force rack and rinion adjustment of tension control mechanism 3, tension force fine tuning device, the rotating cylinder group of tension-detecting mechanism 4, cut off the stub bar of certain-length, smooth processing is done in the steel band end, then, steel band is fixed on the outer cylinder surface of mould by methods such as welding.
Before equipment energising back starts automatic winding program, at first design informations such as the known winding tension theoretical curve and the winding number of plies are imported automatic autonomous cruise speed system, theory control curve according to automatic two the clamping oil cylinder oil pressure that generate of autonomous cruise speed system, motor torque forms the closed loop control program.Then, start winding mode of operation automatically.Winding process is divided into sets up tension force, stable winding and end winding three phases, and cooresponding winding process and control method are as follows successively:
1) setting up the tension force stage, at first, the oil pressure of coarse adjustment clamping oil cylinder, fine tuning clamping oil cylinder reaches its maximum set value respectively, clamps steel band and makes it and can not move.Lag behind a period of time, electric motor starting, output torque constantly increases.In this process, the increase situation of pressure sensor continuous gauging steel band tension force, after the setting value that reaches initial tension, the oil pressure of coarse adjustment clamping oil cylinder still keeps constant value, its gripping power is constant, the oil pressure of fine tuning clamping oil cylinder then reduces gradually according to theoretical curve, produces slip until steel band between upper and lower clamping plate, thus the subordinate phase that the beginning mould twines.
2) the stable winding stage is a very long process consuming time, and during this period, along with the increase of twining the number of plies, the gripping power of coarse adjustment clamping oil cylinder is constant, and fine tuning clamping oil cylinder oil pressure and motor torque change according to theoretical curve.Tension-detecting mechanism is with the extremely automatic autonomous cruise speed system of tension signal continuous feedback, the winding number of plies of coder continuous feedback reality, automatically autonomous cruise speed system is analyzed above-mentioned measured result, calculate, and compare with the winding tension theoretical curve that presets, the generated error control signal, be delivered to clamping oil cylinder electrohydraulic servo system and alternating-current variable frequency motor respectively, with the oil pressure in the adjustment of tonicity fine tuning device clamping oil cylinder and the output torque of motor, thereby realize continuous change tension force winding process.
3) when the winding number of plies that detects reaches setting value, winding process enters into and finishes the winding stage.At this moment, keep the output torque of motor constant, should suitably add the gripping power of hightension fine tuning device clamping oil cylinder, cause steel band to move, motor stops operating.Keep this state a period of time, methods such as utilization welding are fixed the outer steel band of mould.Device powers down is cut off unnecessary steel band at weld then, will twine mould and take off from chuck.So far, a secondary steel band twines the manufacturing process end of pre-stress die.
