Technical Field

The invention belongs to the technical field of steel wire rope flexibility, and mainly relates to a stress relieving and flexibility improving device for steel wire rope production and manufacturing and steel wire rope stranding. The invention relates to a steel wire rope rear deformation device which is used for eliminating or reducing the stress of steel wire rope production and manufacturing and steel wire rope combination, thereby improving the flexibility of the steel wire rope.

Background content

The steel wire rope is a spiral steel wire bundle which is formed by twisting steel wires with mechanical properties and geometric dimensions meeting requirements according to a certain rule. The steel wire rope is a spiral rope which is formed by twisting a plurality of layers of steel wires into strands, and then twisting a certain number of strands by taking a rope core as a center. The method is classified into the following steps according to the steel wire rope twisting method: (1) single strand ropes, also known as single lay ropes, are formed by twisting rope-making steel wire ropes around a central wire or hemp core in layers, and may be twisted in one or more layers. (2) The double-twisted rope is formed by twisting a double-strand rope around a rope core (a steel core or a fiber core), can be twisted into one or more layers of steel wires, and is the most widely used steel wire rope variety. (3) The invention relates to a three-twist rope, which is formed by twisting a double-twist rope as a strand rope around a rope core, and is mainly used for thick steel wire ropes with the diameter of more than 60mm, such as marine steel wire ropes and the like. The steel wire rope has high strength, light dead weight, stable work, difficult sudden whole breakage and reliable work. The processed steel wire rope needs to be coiled into a steel wire rope roll on a special winding drum. Therefore, a rope reeling process exists in the processing and manufacturing process of the steel wire rope, and the steel wires are extruded mutually to have larger plastic deformation during rope reeling, so that certain stress is formed in the steel wire rope after rope reeling, and the synthesized steel wire rope has poor flexibility and is difficult to bend and curl on a winding drum; the presence of stresses within the steel cord also affects the fatigue strength of the steel cord and reduces the life of the steel cord.

In the 'one steel wire rope after-deformation' (patent No. CN 201820173489.6; granted No. CN208023303U) of the chinese utility model patent, a steel wire rope after-deformation device is proposed, in which an upper support plate and a lower support plate are arranged inside a box body, three groups of guide pulleys are uniformly installed on the upper support plate, four groups of guide pulleys are uniformly installed on the lower support plate, and the upper and lower pulleys are staggered. The formed steel wire rope is attached to the bottom of the upper deformation roller and the lower deformation roller from the middle through the top of the steel wire rope, so that the internal stress of the steel wire rope is eliminated. However, in the invention, the steel wire rope can only be bent section by section, so the flexibility method has large influence on the outer steel wire of the steel wire rope, the flexibility effect on the inner strand of the steel wire rope is not obvious, and the flexibility of the whole circumference of the steel wire rope cannot be realized. In the invention of a steel wire rope post-deformation device with multi-layer and multi-column arrangement and spatial dislocation (patent number: CN 202011089049.0; granted number: CN112227097A), the invention provides a steel wire rope post-deformation device, which adopts common straight groove winding drums with multi-layer and multi-column arrangement, and two winding drums of each group are relatively inclined at a certain angle to wind the steel wire rope. However, in the actual processing and production, the probability of producing defective products due to mutual interference of the steel wire ropes in the device is high, and the steel wire ropes are arranged in multiple layers and multiple rows by adopting a single motor to drive a single shaft to rotate, so that the speed synchronization among the shafts is difficult to achieve, and the steel wire ropes are dislocated on the straight groove winding drum during rope winding, so that the stress relief cannot be achieved. The synchronous cog belt transmission is adopted, the whole device is driven by a motor, and the speed synchronization problem is well solved.
