Problems solved by technology

[0002] The existing steel strand twisting production equipment usually uses a tubular machine or a rope skipping machine, which can only produce 1×7 point contact structural steel strands, and the production of 1×19 structural steel strands cannot be twisted in one time, and two Secondary twisting and point contact structure, so there are many processes and low production efficiency. In order to reduce the process and improve work efficiency, the production of 1×19 structural steel strands can be completed at one time. The present invention reorganizes two twisting machines with different structures Combined installation and arrangement into a production line for twisted steel strands, which can realize the independent production of 1×7 point contact structural steel strands, and the joint production of 1×19 line contact structural steel strands
At present, there is no domestic manufacturer capable of producing twisting equipment for steel strands for 1×19 wire contact structure prestressed concrete, which is a new product

Embodiment Construction

[0009] The multi-wire contact structure prestressed steel strand combined twisting equipment structure involved in the present invention, the specific implementation mode will be described in detail in conjunction with the accompanying drawings:

[0010] It consists of a set of skip-rope or tubular stranding machine 1 and a set of basket-type stranding machine 2. The speed change mechanism 3 connects two sets of different stranding machines in series. After series connection, the two machines are synchronized. The whole machine Coordination and matching, single machine can operate independently, and combined machine can be combined to operate; skipping rope or tubular machine 1 is equipped with seven I-shaped wheels, and can produce 1×7 structural steel strands when used independently; basket-type stranding machine 2 Twelve basket racks are installed, and twelve I-shaped wheels and skipping rope or tubular stranding machine 1 are installed in series to form a set of steel stran...

Abstract

The invention discloses a multi-silk thead contact structure pre-stress assembled entwisting equipment, comprising a skipping rope type or tubular stranding machine (1) and a set of basket type stranding machine (2) connected in series by a speed change mechanism (3). 1*7 structural steel stranded wires can be produced by a single machine, and 1*19 thread contact structural steel stranded wires can be produced by the assembled machine. Accommodation area of the factory building is relatively small, equipment investment is saved, and production efficiency is increased.

Description

1. Technical field [0001] The invention relates to a steel strand twisting production equipment, in particular to a combined twisting production equipment capable of producing multi-wire contact structure prestressed steel strands. 2. Background technology [0002] The existing steel strand twisting production equipment usually uses a tubular machine or a rope skipping machine, which can only produce 1×7 point contact structural steel strands, and the production of 1×19 structural steel strands cannot be twisted in one time, and two Secondary twisting and point contact structure, so there are many processes and low production efficiency. In order to reduce the process and improve work efficiency, the production of 1×19 structural steel strands can be completed at one time. The present invention reorganizes two twisting machines with different structures The combined installation is arranged into a production line for twisted steel strands, which can realize the independent p...
