Double barrel series-unit production device for twisting steel strands

Abstract

The invention discloses a double barrel series-unit production device for twisting steel strands. The device comprises a plurality of barrels, a main driving shaft, a motor, a coupler, a transmission case, a belt wheel, a clutch and a connection base and can be used for twisting steel strands in a line contact structure and of multiple specifications such as 1*2, 1*3, 1*7 and 1*19 and the like, and can complete the whole twisting process of the steel strands at one time. The device has the advantages of simple structure and high production efficiency and is convenient to operate.

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...
