Abstract
Description
technical field
[0001] The invention belongs to the field of steel strand manufacturing, and relates to a steel strand twisting production device of a double-position cylinder series unit type. Background technique
[0002] The 1×2, 1×3, 1×7, 1×19 prestressed concrete steel strands currently used in the field of construction machinery are all produced by twisting and stranding machines of special specifications. The stranding machines are not compatible to produce steel strands of different specifications, and the strands produced by the traditional twisting stranding machine are point contact structures. Compared with the wire contact structure strands, this type of strands lower strength and durability. In the actual production process, in order to produce multi-standard steel strands for prestressed concrete, it is necessary to manufacture twisting stranding machines with different structures, which greatly increases the investment cost of equipment, and the production e...
