Abstract
A double-hardness cotton-spinning ring with high precision comprises a ring base body which is provided with an inner runway (3) and an outer runway (4), and is characterized in that the ring base body is a bearing steel ring whose upper hardness and lower hardness are different, wherein the hardness of the upper portion (1) of the ring base body is 81.5<= HRA <= 100, and the hardness of the lowerportion (2) of the ring base body is HRC <38. The double-hardness cotton-spinning ring has high precision, wherein the circular degree is lower than 10mm, and the planeness lower is lower than 5mm, and the double-hardness cotton-spinning ring has excellent consistency, does not have running-in time, is wearable, greatly improves the service life, and has low manufacture cost, simple manufacture process and high production efficiency.
Description
Technical field
The utility model relates to a kind of rings, the high-precision double-hardness cotton spinning ring that uses on the ring spinner in particularly a kind of cotton spinning industry.
Background technology
Rings is the critical component of ring throstle and common ring spinner, supporting twisting and the coiling of finishing yarn jointly such as it and steel traveler, spindle, spool.The quality of rings quality directly influences spinning quality, spinning efficiency and economic benefit.Rings is of low quality, the spinning tension instability, and spinning the Yarn filoplume that comes increases, and the spun yarn bar is done and is worsened, and spinning end breaking is increased, and production efficiency descends.How producing high-quality rings is the technical barrier that those skilled in the art need research and solve.
Bearing steel rings is with its phosphorus content height, and hardness height, quenching degree are good etc., and advantage becomes the development trend of cotton spinning ring from now on, service life that its ABRASION RESISTANCE is good, prolonged rings and all showing better performance aspect antisticking wearing and tearing and the fatigue wear; The bearing steel rings smooth surface, circularity, flatness, the depth of parallelism etc. all are better than the common plane rings, and the steel traveler running rail is unobstructed, and spinning tension is stable, and broken end, fibrous index all can be controlled at better level during thousand ingots.But existing bearing steel rings is owing to the reason of manufacturing technique exists precision low, and the deficiency of uniformity difference often exists than big-difference with a collection of its roundness of the bearing steel rings of producing, and uses like this.
The utility model content
The purpose of this utility model just provides the different high-precision double-hardness cotton spinning ring of a kind of rings matrix upper and lower hardness, and the roundness of this rings is lower than 10 microns, flatness and is lower than 5 microns, and precision is very high, high conformity.
The purpose of this utility model is to realize by such technical scheme, it includes the rings matrix, the rings matrix is provided with inner track and outer track, the rings matrix is the different bearing steel rings matrix of top hardness and bottom hardness, wherein the hardness on rings matrix top is: 81.5≤HRA≤100, the hardness of rings matrix underpart is: HRC＜38.
The Rockwell hardness on its rings matrix top of high-precision double-hardness cotton spinning ring described in the utility model is 81.5≤HRA≤100, and the bottom is not heated and quenches, and its hardness still keeps the hardness of bearing steel itself, and hardness is: HRC＜38.In use, steel traveler is high speed rotary on the runway of rings, requires rings matrix top must reach certain rigidity, and particularly its hardness of interior outer track of the rings of the usefulness of confession steel traveler high speed rotary must reach 81.5≤HRA≤100 hardness numbers; The inside and outside runway hardness of rings is too small, the coefficient of friction of steel traveler and rings runway is big, rings to walk the ripe phase long, wearing and tearing and high temperature (more than 300 ℃) that steel traveler and rings produce because of friction, can make steel traveler fly off, burn or turn round unstable, cause moment shake or the Wedged of steel traveler on the rings runway to live, these phenomenons all can make Yarn break.The task of steel traveler high speed rotary is not born in the bottom of rings matrix, its hardness need not reach the such hardness in rings matrix top, need not in the process of processing heating quenching to be carried out in the bottom of rings handles, employing is carried out the processing of part heating quenching to rings matrix top, obtains rings matrix top hardness height and the little Dual Hardness Steel neck matrix of rings matrix underpart hardness.This Dual Hardness Steel neck is in heat treatment process, the rings matrix underpart is not subjected to high temperature, can not deform, can pin down the distortion of rings matrix top in high-temperature heating, the rings bulk deformation of this pair of hardness is little or indeformable, has improved the precision of rings greatly, and the roundness of rings is lower than 10 microns, flatness and is lower than 5 microns, the precision height, high conformity.
Owing to adopted technique scheme, the utlity model has following advantage: cotton spinning ring precision height of the present utility model, roundness is not more than 10 microns, flatness and all is not more than 5 microns, high conformity is not walked the ripe phase, and is wear-resisting, improved service life greatly, and cost of manufacture is cheap, and manufacture craft is simple, the production efficiency height.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
1. rings matrix top; 2. rings matrix underpart; 3. inner track; 4. outer track.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, cotton spinning ring of the present utility model comprises the rings matrix, the rings matrix be provided with inner track 3 and outer track 4, the rings matrix is top hardness and the different bearing steel rings of bottom hardness, wherein the hardness of rings matrix top (1) is: 81.5≤HRA≤100, the hardness of rings matrix underpart 2 is: HRC＜38.
High-precision double-hardness cotton spinning ring described in the utility model, the top of rings matrix comprise inner track 3 and outer track 4 and part rings matrix.
High-precision double-hardness cotton spinning ring described in the utility model, the top of rings matrix comprise inner track 3 and outer track 4.
The Rockwell hardness on its rings matrix top of high-precision double-hardness cotton spinning ring described in the utility model is 81.5≤HRA≤100, and the bottom is not heated and quenches, and its hardness still keeps the hardness of bearing steel itself, and hardness is: HRC＜38.In use, steel traveler is high speed rotary on the runway of rings, requires rings matrix top must reach certain rigidity, and particularly its hardness of interior outer track of the rings of the usefulness of confession steel traveler high speed rotary must reach 81.5≤HRA≤100 hardness numbers; The inside and outside runway hardness of rings is too small, the coefficient of friction of steel traveler and rings runway is big, rings to walk the ripe phase long, steel traveler and rings produce wearing and tearing and high temperature (more than 300 ℃) because of friction, can make steel traveler fly off, burn or turn round unstable, cause moment shake or the Wedged of steel traveler on the rings runway to live, these phenomenons all can make Yarn break.The task of steel traveler high speed rotary is not born in the bottom of rings matrix, its hardness need not reach the such hardness in rings matrix top, need not in the process of processing heating quenching to be carried out in the bottom of rings has handled, employing is carried out the processing of part heating quenching to rings matrix top, obtains rings matrix top hardness height and the little two rings matrixes of rings matrix underpart hardness.This Dual Hardness Steel neck is in heat treatment process, the rings matrix underpart is not subjected to high temperature, can not deform, can pin down the distortion of rings matrix top in high-temperature heating, the rings bulk deformation of this pair of hardness is little or indeformable, has improved the precision of rings greatly, and the roundness of rings is lower than 10 microns, flatness and is lower than 5 microns, the precision height, high conformity.
