Description
Affiliated technical field
The present invention relates to the manufacturing technology of high-speed wire spinning machine, particularly a kind of spinneret atomization cooling device of high-speed wire spinning machine.
Background technology
Laying head be high-speed rod produce in by the wire spinning rolling of rolling in order to collect key equipment.Laying head is mainly made up of several parts such as input rotor, output rotor, gear-box, safety guard and bases, and wherein output rotor is made up of turning cylinder (also claiming hollow shaft), laying head, spinning plate etc. again.The entrance point of spinneret pierces into the center of turning cylinder (hollow), and the port of export is arranged on the spinneret bearing of laying head.Because spinneret is with output rotor High Rotation Speed, wire rod enters spinneret from spinneret import, passes from spinneret outlet, is just wound into the coil of wire, " tells " and falls on loose volume conveyor roller, then cooling, collection through spinning plate.The speed of wire rod when through Laying head spinneret is more than 90m/s, and the wire rod of high-speed motion and curved spinneret inwall produce violent friction; Laying head laying temperature is more than 900 DEG C, and wire rod is continuously by spinneret, and spinneret is also heated to 900 DEG C of left and right, and high temperature reduces the abrasion resistance of spinneret greatly; Moreover the at high temperature stone iron scale of surperficial oxidized generation one deck of wire rod, the directly wearing and tearing of aggravation to spinneret.Generally adopt at present logical compressed-air actuated method in spinneret, in the hope of blowing down the iron scale accumulating in spinneret and reducing spinneret temperature, thereby improve the spinneret life-span, effect is unsatisfactory.What spinneret life-span was long can mistake steel three, 40,000 tons, short only have four, five kilotons.Short direct result of spinneret life-span is exactly that maintenance cost increases, and the high-speed rod steel rolling line spinneret consumption costs of a year having reaches one unexpectedly, 2,000,000 yuan.The time that changing in addition a spinneret needs can be lacked 40 tons of left and right of rolled wire.In addition, also the wearing and tearing of Chang Fashengyin spinneret cause rolling line heap steel accident, cause waste product, even damage equipment.
Summary of the invention
In order to overcome existing high-speed wire spinning machine spinneret because can not get the fully deficiency of cooling rapid wear, the invention provides a kind of spinneret atomization cooling device of high-speed wire spinning machine, this device can not only improve the cooling effect to spinneret, and can between wire rod and spinneret, produce certain lubrication, thereby extend resistance to wearing the life-span of spinneret.

The principle that the present invention solves technical scheme that its technical problem adopts is as follows:
(1) function of Laying head has determined to adopt gas as medium, spinneret to be carried out under cooling prerequisite, the technical program improves the specific heat of cooling medium by water and air atomizing, strengthen the cooling dynamics to spinneret, improved the wearability of spinneret.
(2) adopt atomization cooling, hydrone forms moisture film on spinneret surface, plays certain lubricated and protective effect, has reduced the wearing and tearing of wire rod to spinneret, the life-span of having improved spinneret.
(3) mode that described atomization cooling device adopts atomization water self pressure to add " tube fluid flow at high speed produces negative pressure to tube wall causes tube wall outer fluid to be passed in tube wall aperture suction line " is carried out atomization, and simple in structure, atomizing effect is good.For the suction function that strengthening flow produces, it is large that middle little two is made in the cross section of the air flue through hole of the housing of described atomization cooling device, in the cross section at water spout place minimum.
(4) adjusting lever is set, to adjust the water yield, can best atomizing effect.
Feature of the present invention and further improvement are:
(1) feature of described atomization cooling device is water to be mixed with air produce fog, has improved medium specific heat, has strengthened the cooling effect to spinneret.
