Abstract
A method for twisting a multi-wire contact equidirectional twisted steel wire rope is characterized in that during twisting, the twisting of each strand must be controlled to be minus 180 degrees to minus 360 degrees, the diameter of a working roller of a pre-deformer is selected to be 3-4 times of the diameter of the strand during twisting, the bending depth of the pre-deformer is 1.25-1.3 times of the diameter of the rope, the distance between roller ends is 80-85 percent of the twisting distance of the steel wire rope, the strand is bent in the direction opposite to the twisting direction of the rope, a pressing tile is compressed for production, a turning device is not adopted for upward force production during twisting, a cone is used for prying the strand steel wire without loosening, and the twisting of the steel wire rope is less than or equal to. The invention solves the problem of unbalanced steel wire moment caused by strand breaking strength during rope twisting, the steel wires in the strands are not loosened, the fatigue resistance of the steel wire rope is improved, and the service life of the steel wire rope is prolonged.
Description
Technical Field
The invention relates to a twisting method of a multi-filament contact equidirectional twisted steel wire rope, belonging to the technical field of metal cable processing.
Technical Field
The multi-wire contact same-direction twisted steel wire rope product is mainly used as one of materials required by people and objects carried in important places such as mine hoisting, aerial ropeways, coal mine monkey vehicles, tourist attraction ropeways and the like. When the same-direction twisted steel wire rope is produced in the past, in order to ensure that the steel wire rope is not loose and does not become shell, the twisting is tight, the twisting of the strand is controlled within the range of +/-90 degrees, when the twisting of the strand is controlled at 90 degrees, the steel wires in the strand are loosened, and in the twisting process of the same-direction twisted steel wire rope, the moment of the steel wires in the strand is unbalanced due to the fact that the strand is in a breaking state when the strand is twisted, so that the steel wires in the strand are loosened, in the past, the problem that the steel wires in the steel wire rope are loosened is solved by basically adopting a production mode that a turnover device applies force to the strand while twisting when the strand is twisted, but the steel wire rope twisting is increased due to the production mode, and the service life of the steel. The twisted steel wire rope is twisted by a new method that the twisting of strands is controlled to be-180 degrees to-360 degrees during strand twisting, the diameter of a working roller of a pre-former is 3-4 times of the diameter of the strands during rope twisting, and the bending multiple of the pre-former is 1.25-1.3 times of the diameter of the rope, so that the strands do not need to be stressed, the twisted steel wire rope is compact in structure, and strands are not loosened. The twisting quality reaches and meets the use requirements of users, and meanwhile, the service life of the steel wire rope is prolonged.
The technology has no report of the same technical content on public media.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a twisting method of a multi-wire contact same-direction twisted steel wire rope, which solves the problem of strand looseness caused by unbalanced steel wire moment during strand twisting by controlling strand twisting during strand twisting, and has the advantages of good fatigue resistance of the steel wire rope product and prolonged service life.
A twisting method of a multi-filament contact same-direction twisted steel wire rope is characterized by comprising the following implementation steps:
(1) strand twisting
During stranding, selecting a proper line pressing tile and a rear deformer according to the size of the strand diameter, pressing the line pressing tile tightly, and checking that the twisting of each strand must be controlled to be-180 to-360 degrees;
(2) twisted rope
Selecting a proper rope twisting machine according to the specification of the steel wire rope, selecting a pre-former with the working roller diameter being 3-4 times of the diameter of a strand, selecting a pre-former with the bending depth being 1.25-1.3 times of the diameter of the rope, selecting the roller end distance being 80-85% of the lay length of the steel wire rope, bending the strand in the direction opposite to the lay length, and pressing a line pressing tile for production.
When twisting rope, the turning-over device is not adopted for top production, the awl is used for prying the strand steel wire to prevent the steel wire from loosening, and the twisting degree of the steel wire rope is less than or equal to-360 degrees.
The control of twisting is beaten the thigh usually among the conventional art at 90 within ranges, and the strand well steel silk will appear becoming flexible when twisting the thigh, and the wire moment is uneven in the thigh in the state of being broken strength at the rope twisting in-process thigh in addition syntropy twisting wire rope, leads to the strand well steel silk not hard up.
When the steel wire rope is twisted, the twisting of the strands is controlled within the range of-180 degrees to-360 degrees, the problem of unbalanced steel wire moment caused by strand breaking force when the strands are twisted is solved, the product quality defect of steel wire loosening in the strands is overcome, the fatigue resistance of the steel wire rope is improved, and the service life of the steel wire rope is prolonged.
Detailed Description
The invention relates to a twisting method of a multi-thread contact equidirectional twisted steel wire rope, which comprises the following implementation steps:
(1) strand twisting
During stranding, selecting a proper line pressing tile and a rear deformer according to the size of the strand diameter, pressing the line pressing tile tightly, and checking that the twisting of each strand must be controlled to be-180 to-360 degrees;
(2) twisted rope
Selecting a proper rope twisting machine according to the specification of the steel wire rope, selecting a pre-former with the working roller diameter being 3-4 times of the diameter of a strand, selecting a pre-former with the bending depth being 1.25-1.3 times of the diameter of the rope, selecting the roller end distance being 80-85% of the lay length of the steel wire rope, bending the strand in the direction opposite to the lay length, and pressing a line pressing tile for production.
When twisting rope, the turning-over device is not adopted for top production, the awl is used for prying the strand steel wire to prevent the steel wire from loosening, and the twisting degree of the steel wire rope is less than or equal to-360 degrees.
The invention solves the problem of strand twisting during strand twisting, thereby solving strand wire loosening caused by unbalanced steel wire moment during rope twisting of steel wires in strands.
