Description
Technical field
The present invention relates to Laying head technical field more particularly to a kind of Laying heads with multistage combination forming device.
Background technique
Laying head is the key equipment for collecting the wire spinning of rolling with benefit in rolls in high-speed wire mill.Existing high speed
For the mill speed of wire rod production line up to 120m/s or more, this also proposed higher technical requirements to Laying head.Laying head by
The components such as transmission device, hollow shaft, laying head, spinneret, bevel gear composition.Laying head passes through tooth by a motor driven
Bevel-gear sett engagement drives hollow shaft rotation in roller box, and spinneret is the working part of high-speed rod product lopping, passes through pipe
Folder is mounted on laying head, and laying head is bolted with hollow shaft, and when Laying head works, wire rod is by Laying head entry conductor
It is sent into the hollow shaft of Laying head, hollow shaft drives laying head and spinneret to rotate together with, and keeps the wire rod entered in hollow shaft logical
The spinneret for crossing rotation exports tangent to periphery direction discharge coil along spinneret, and is smoothly poured on air-cooled roller-way, shape
At continuously coil.
When wire rod passes through high-speed rotating spinneret, by the normal pressure of spinning tube wall, force of sliding friction, itself high speed
Under the collective effect of rotary centrifugal force, as the shape of spinneret is gradually curved deformation, it is gradually curved by linear motion, and spitting
Fiber tube outlet reaches required curvature, forms spiral winding, and the lopping of uniform and stable spues.
Laying head most common failure and problem have:
(1) whipping, it is non-round easily to occur coil disorder, lopping when wire rod tail portion spues through Laying head, size is uneven, arrangement not
Together, whipping amplitude improves with mill speed and more becomes serious.
(2) spit circle it is non-round, after Laying head starts Tu Quan, circle segment shape it is bad or spinning circularity it is inadequate, cause to control cold rail
Piling of steel, steel-fastening influence production are normally carried out frequent occurrence at road sum aggregate volume station.
(3) spinning swings, in silking process, the phenomenon that coiling for occurring spuing swings, to a certain degree
Upper increase subsequent set rolls up difficulty, and seriously affects coiling packaging quality.
(4) spinning tube lifetime is short, and spinneret service life is short not only to will increase production cost, and the tube wall that spins when serious can also
It is worn through, piling of steel accident occurs.
Spinneret is the working part and key part of Laying head, and technology status directly decides the technology water of Laying head
It is flat.Spinneret track is that complicated space curve is divided into three parts: introduction segment, deformation section, plastic section.
Existing spinneret is formed with one whole high-alloy steel pipe hot bending, is suffered from the drawback that
1. utilization rate is not high: being analyzed according to spinneret space curve, what is mainly worn is deformation section；In actual production
Almost all of spinneret is all and to deform segment length since deformation section excessive wear leads to life failure only to account for spinneret total
It is about 20%, this is the huge wasting of resources.
2. replacement is inconvenient: the space curve of spinneret complexity causes replacement spinneret workload very big, needs to dismantle all
Pipe clamp and the part that interferes of front end, some types even only remove laying head from transmission case, could replace spinning
Pipe.
