Description
Technical Field
The invention relates to the technical field of stranding machines, in particular to a twisting method of an efficient double-twisting stranding machine.
Background
The steel wire twisting product is produced by rotating a plurality of monofilaments through twisting equipment, and is generally produced by adopting a single twisting machine and a double twisting machine, so that the production efficiency of the steel wire twisting is limited.
The method for controlling the lay length of the former steel wire stranding machine adopts a proportioning driving wheel and a driven wheel of a mechanical reduction gearbox to adjust a gear reduction ratio and change the speed of a traction wheel so as to control the lay length of a steel wire strand. In addition, the gear reduction box needs to be maintained regularly, engine oil in the gear reduction box needs to be replaced, and if the sealing performance of the gear reduction box is not in place, the situation of engine oil leakage can be caused. Besides engine oil, the bearings need to be replaced regularly, and the bearings are prevented from being seriously worn to cause seizure.
The flywheel disc plays a role of stranding in a machine tool, namely, a plurality of strands of steel wires are twisted together like a rice twisting rope to form a metal rope. Generally, the running speed of a steel wire stranding machine refers to the speed of a flywheel disc, the higher the speed of the flywheel disc is, the higher the production efficiency of a machine tool is, and the highest running speed is usually set under the condition that the overall performance of the machine tool can bear.
The traction wheel plays a traction pulling force in the machine tool to pull the twisted metal rope out of the machine tool, so that the twisted metal rope is wound up by the spool of the winding machine. Therefore, the lay length of the metal rope can be changed by only changing the speed ratio between the flywheel disc and the traction wheel of the machine tool, and under the condition that the running speed of the flywheel disc is unchanged, the faster the speed of the traction wheel, the larger the lay length, and the slower the speed of the traction wheel, the smaller the lay length.
The method for controlling the lay length by changing the speed of the traction wheel by using the mechanical reduction gearbox has the defects, so that the traction wheel can be driven by a servo motor which is widely applied to industrial automation to replace the mechanical reduction gearbox, and the servo motor has the advantages of high control precision, no maintenance, long service life and the like. If the traction wheel is driven by the servo motor, the speed of the traction wheel can be changed by changing the speed of the servo motor of the traction wheel, namely the lay length of the metal rope is changed. Therefore, the four-fold stranding equipment and the stranding method can be developed, constant-speed forward and reverse rotation of the two flywheel discs is realized through forward and reverse rotation of the inner main shaft and the outer main shaft, and the purpose of multi-fold stranding of the steel wires is achieved by combining rotation speed control of the servo motor.
