Description
The top layer treatment process and the device of major parts-rings of the spinning frame in producing the present invention relates to weave.
Rings is one of consumable accessory of spinning frame.The domestic rings material of China generally adopts ordinary low-carbon steel, and the surface hardness after conventional carbon, nitrogen (C, N) ooze processing altogether can only reach about 850Hv, and hardness is inhomogeneous, and work-ing life is only about 1 year.The rings material adopts low-carbon alloy steel in the world, and the hardness after the surface treatment is greater than 1000Hv, and can reach about 3 years work-ing life.But low-carbon alloy steel cost height, manufacturing involves a wide range of knowledge, the promotion and implementation difficulty.
The purpose of this invention is to provide technology and the device thereof that handle on a kind of rings top layer, this technology and device can make the rings top layer working face (i.e. the logical surface of the race that contacts with Steel Traveler) of ordinary low-carbon steel material realize noncrystalline state, thereby improve the hardness on rings surface, increase the service life.
The present invention is achieved in that the processing of soft steel rings working face top layer being infiltrated non-crystalline state forming elements such as C, N, B, Si or P, must be noted that the generation and black generation mutually of control ε phase in the treating processes; Rings behind the infiltration non-crystalline state forming element is placed on the custom-designed device, make laser fast thawing chilling and handle, make the rings surface form noncrystalline state.
The amorphous treatment unit of custom-designed rings mainly partly is made up of laser source, base, electric motor, transmission turning mechanism, rings anchor clamps etc.Base comprises base plate and the upright piece of base plate, plays the whole device of supporting; Electric motor adopts DC formula torque motor; Transmission turning mechanism mainly comprises the worm and wormwheel of rotating shaft, drive shaft, the panel that is driven by rotating shaft and the gear that drives anchor clamps.The rings anchor clamps adopt magnetic clamp, mainly comprise the magnet steel, magnetic circuit plate, the magnet nylon ring that hold rings, and make rings realize the location stop rod of not being in the mood for rotating for eliminating the influence that diameter of ring and deviation from circular from cause.
Advantage of the present invention is to adopt the common low carbon steel to make rings, and low cost of manufacture has improved the hardness and the toughness on rings working face top layer after the laser treatment, approach the rings of low-carbon alloy steel material work-ing life.

2The relation of sweep velocity and hardness during laser treatment.
Below the present invention is described in further detail.
The technology of the amorphous processing of rings comprises pre-treatment and laser treatment two portions.The technical process of pre-treatment is: No. 20 ordinary low-carbon steel rings manufacturing → C, N ooze processing → quenching → polishing → deoil altogether, adopt known thermal treatment process in the ordinary low-carbon steel rings, to infiltrate C, N in this flow process, must be noted that the generation and black generation mutually of ε phase during processing.
The technological process of laser treatment is in proper order: and rings material loading → device rotation → laser lock opens (control automatically) → time control → laser lock and cuts out → and rings falls to getting → the rings sampling analysis.
The structure of laser machining device as shown in Figure 1.During laser treatment, rings 15 is placed on the magnet steel 10, behind the actuating motor 13, motor gear 5 transfer motion speed changing gears 6 make the combination rotation of being made up of bearing core print seat 17, magnetic circuit plate 7 and magnet steel 10, have driven rings 15 rotations.The change of rings 15 speed of rotation can be achieved by the electric current of transposing gear or change electric motor 13.After worm screw 16 is rotated, rotating shaft 1 is rotated, and drive whole front panel 4 rotations, at this moment can change the relative angle between rings 15 and the laser beam, to satisfy processing requirements.Because the aperture of rings 15 exists size and roundness deviation, under condition, be not in the mood for rotation when requiring rings 15 to rotate automatically, to eliminate the influence that diameter and deviation from circular from cause near location stop rod 11.No slip is skidded between this special magnetic clamp and the rings 15,, but can radially slide.The rotation center of magnetic clamp does not overlap with the rotation center of rings 15, and outside deflection 1.5-2.5 millimeter, 15 of rings can be close to location stop rod 11 and move about with the circularity variation of self.
High energy pulse nd glass laser, high repetition frequency YAG laser and high-power CO have been adopted in the non-crystalline state treating processes
2Laser deals with rings working face (being runway) top layer, has studied the possibility that forms amorphous layer, and laser processing technique condition and the hardness on rings working face top layer, processing back and the relation between the wear resistance.Can reach the work-ing life that non-crystalline state is handled the back rings 〉=2 years.
Ordinary low-carbon steel rings C, N ooze processing parameter that back laser non-crystalline state handles altogether and handle that afterwards the relation between the rings surface hardness is as follows: laser treatment forms that amorphous condition depends primarily on the tissue signature on the laser power density that is radiated at the metallic surface, action time, treated material surface and to the absorption feature of laser.Only under the short condition of laser power density height, action time, the heat of rings top layer gained just has little time to import into the rings matrix, this moment rings top layer melting efficiency height, and the rings matrix is in cold conditions, cause the thermograde of fusing top layer and matrix to increase, improve the condensate depression on fusing top layer, can satisfy amorphous formation condition.Therefore, in the treating processes, the nd glass laser power density adopts 9 * 10
4W/cm
2, action time 100-200 μ s; The YAG laser power density adopts 1.2 * 10
6W/cm
2, action times 100 μ s-40ns; CO
2Laser power density 10
5W/cm
2More than, sweep velocity 400-500mm/s.The C of ordinary low-carbon steel rings, N co-penetration layer all can be realized non-crystalline state under the above-mentioned condition.Show that the rings top layer forms amorphous important symbol and has two: one, surface hardness reaches more than the 1000Hv, and the 2nd, electron diffraction is disperse style (the polycrystalline state electron diffraction pattern is diffraction ring) like a slice white clouds.Under the lasing time rigid condition, the hardness on rings surface has a maximum value (seeing Fig. 2,3,4,5) with the increase of power density or energy density after handling, and three kinds of laser treatment have same this rule.When laser power density or energy density were suitable, action time, length was little to the surface hardness influence of handling the back rings; But when power density was too high or too low, surface hardness significantly improved (seeing Fig. 6,7) with the increase of action time.
The processing parameter that the laser non-crystalline state was handled after ordinary low-carbon steel rings C, N oozed altogether is as follows with the relation of handling the back amorphous layer depth of rings (that is thickness): owing to amorphous layer thickness is generally very thin, be micron dimension, this thickness and laser non-crystalline state treatment process relating to parameters, when laser power density does not reach enough under the big situation, the increase of action time is little to the thickness effect of amorphous layer; But power density is enough big, reaches 10
7W/cm
2Under the above situation, action time is remarkable to the effect that increases amorphous layer thickness.
