Abstract
The utility model discloses a kind of high rigidity drawing roller, comprise draw-off godet, be coated with the hard chrome coating outside the draw-off godet surface, outside the hard chrome coating, be coated with and be coated with anti abrasive chromium nitride film layer; The wear-resistant chromium nitride film layer of this kind can make the hardness of draw-off godet reach more than the HV1800, drawing roller can normally be used 5 years at least continuously, prolonged service life greatly, the big defective of winding tension difference that has caused when having reduced drawing roller reparation or replacing, improved homogeneity of product, also avoid drawing roller frequently to electroplate and repaired the pollution that brings, control suitable roughness simultaneously, a yield is improved, reduced working strength of workers, increase work efficiency, be more suitable for the drawing-off of high strength industrial filament, provide appointed condition to the upgrading of high-tenacity industry silk for realizing the general industry silk.
Description
Technical field
The utility model belongs to spinning industrial technology field, relates to the drawing roller of a kind of high rigidity, wear-resistant, long service life.
Background technology
Drawing roller is mainly used in the spinning field, be installed on the drafting system, the drawing roller overlay coating that uses in the spinning field mostly is hard chrome at present, its hardness is HV800～1100, use hard chrome coating to have some inevitable shortcomings, this coating surface hardness is low when mainly showing the high drafting spinning, wear-resisting poor, service life is short, be unfavorable for steady in a long-term production, heavy wear just appears in the general 1-1.5 that uses when conventional spinning, and the roller surfaces that need more renew is arranged in pairs or groups inhomogeneous thereby produce new roller with the roller thickness that has decreased on the surface, cause uniform in quality poor, above-mentioned phenomenon is particularly outstanding when particularly spinning high strength industrial filament.The finish that uses in becoming fine process easily carbonization at high temperature simultaneously very easily with hard chrome plating layer roller surfaces bonding, causes lousiness, fracture of wire, and product yield is low.
Need electroplate during hard chrome plating drawing roller surface heavy wear and repair or change, but electroplating industry is the industry of high pollution and highly energy-consuming, can bring pollution to environment, do not meet that national encourage growth is energy-conservation, the innovation policies requirement of environmental protection new technology.
The utility model content
The purpose of this utility model is to provide the drawing roller of a kind of high rigidity, wear-resistant, long service life.
For achieving the above object, the utility model by the following technical solutions: a kind of high rigidity drawing roller, comprise draw-off godet, the draw-off godet surface is coated with the hard chrome coating, is coated with to be coated with anti abrasive chromium nitride film layer outside the hard chrome coating.
The thickness of described chromium nitride film layer is less than 10 μ m.
The roughness of described chromium nitride film laminar surface is 1.0～4.0 μ m.
Adopt high rigidity drawing roller of the present utility model, the anti abrasive chromium nitride film layer of coating outside the plating hard chromium on surface draw-off godet, the thickness of this chromium nitride film layer is less than 10 μ m, the roughness of chromium nitride film laminar surface is 1.0～4.0 μ m, the hardness of draw-off godet is reached more than the HV1800, good ABRASION RESISTANCE, corrosion resistance and heat-resisting quantity (not changing between 300～450 ℃) are arranged, good low frictional compatibility be arranged with fiber, the strong adhesion of wear-resistant rete of while, chemical stability is good.The drawing roller of the wear-resistant chromium nitride film layer of this kind coating can normally be used 5 years at least continuously, prolonged service life greatly, the big defective of winding tension difference that has caused when having reduced drawing roller reparation or replacing, improved the quality conformance of spinning, also avoid drawing roller frequently to electroplate and repaired the pollution that brings, control suitable roughness simultaneously, a yield is improved, and reduced working strength of workers, increase work efficiency, be more suitable for the drawing-off of high-strength skill industry silk, provide appointed condition to the upgrading of high-tenacity industry silk for realizing the general industry silk.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Embodiment 1: high rigidity drawing roller as depicted in figs. 1 and 2, comprise draw-off godet 1, draw-off godet 1 surface is outer to be coated with hard chrome coating 2, the anti abrasive chromium nitride film layer 3 of coating outside hard chrome coating 2, the thickness of chromium nitride film layer 3 is 3.8 μ m, and the roughness on chromium nitride film layer 3 surfaces is 3.6 μ m.
The case hardness that the method for employing nanometer microprobe is measured this chromium nitride film plating layer drawing roller reaches HV1800, and the result shows that the former hard chrome plating layer of its hardness ratio has improved more than 1 times.
Embodiment 2: be with the difference of embodiment 1: the thickness of chromium nitride film layer 3 is 10 μ m, and the roughness on chromium nitride film layer 3 surfaces is 1.0 μ m.
Embodiment 3: be with the difference of embodiment 1: the thickness of chromium nitride film layer 3 is 5 μ m, and the roughness on chromium nitride film layer 3 surfaces is 4.0 μ m.
Claims (3)
1, a kind of high rigidity drawing roller comprises draw-off godet, and the draw-off godet surface is coated with the hard chrome coating, it is characterized in that: be coated with outside the hard chrome coating and be coated with anti abrasive chromium nitride film layer.
2, high rigidity drawing roller as claimed in claim 1 is characterized in that: the thickness of described chromium nitride film layer is less than 10 μ m.
3, high rigidity drawing roller as claimed in claim 1 or 2 is characterized in that: the roughness of described chromium nitride film laminar surface is 1.0～4.0 μ m.
