Detailed description of the invention
Referring to Fig. 1-3, the rings-steel traveler device according to the ring ingot shape spinning machine of present invention is described.With reference to Figure 1A, 1B, 1C, rings-steel traveler device comprises rings 11 and along rings 11 slidably steel traveler 12.Rings 11 has flange 11A, and it has T-shaped on cross section; And steel traveler 12 has C shape on cross section.Rings 11 is made up of bearing steel, and has hard chromium coating 13, and this chromium coating has thickness at about 10 to 20 μm, as shown in figs. ib and 1 c.
As is shown in fig. 1 c, rings 11 has multiple recess 14, in the surface that the steel traveler 12 that recess is at least formed in rings can slide along it.In the present example, recess 14 is formed in the inner surface of flange 11A of rings 11.
As shown in Figure 2A and 2B, each recess 14 has round-shaped openend and spherical recessed surface (curved surface).In other words, each recess is formed by rounded opening edge and bending inner surface.The round-shaped of opening of recess needs not be real circle, but it comprises its variant, and it may be because the reason of the error in recess 14 formation is formed.Recess 14 is so formed, thus makes the half of the radius of circular open or diameter D be equal to or greater than the depth H of recess 14.In the present example, the opening of recess 14 is between 10 and 100 μm.
Recess 14 is formed can by being irradiated to the surface that recess 14 will be formed wherein by femtosecond pulse bundle, high output picosecond pulse laser bundle or ps pulsed laser and ns pulsed laser bundle.
Hereafter the operation with the rings-steel traveler device of configuration described above will be described.In the spinning operation of spinning machine, to send and the yarns Y (as shown in Figure 1 C) of passing steel traveler 12 is wound on around the (not shown) bobbin with High Rotation Speed from the drafting unit (not shown) of spinning machine.During the normal spinning operation of ring ingot shape spinning machine, the maximum rotative speed of the ingot of spinning machine is approximately 25000 revs/min, and steel traveler 12 slides on the flange 11A of rings 11, stands the winding tension of yarns Y simultaneously.Although the sliding position of steel traveler 12 may slightly change according to its translational speed, steel traveler 12 still slidingly contacts with lower surface in flange 11A, as is shown in fig. 1 c.
Because steel traveler 12 with high-speed slide, describedly produces frictional heat on flange 11A on the slidingsurface of steel traveler 12 and flange 11A.Unless discharged described heat efficiently, otherwise steel traveler 12 subjects to too early degeneration and blocks problem.
During the spinning operation of spinning machine, the rotation of bobbin and steel traveler 12 produce the adjoint air stream 15 (below be called for short air-flow) along the inner surface of the flange 11A of rings 11 along the slip of rings 11.Form the partial-flow of the air-flow 15 flowed on the surface of recess 14 wherein by recess 14, as shown in Figure 3.Be different from traditional recess 32 with vertical wall surface 32, the inner surface of the recess 14 formed by curved surface allows air-flow 15 to smoothly pass recess 14, does not produce whirlpool, thus the air exchange in recess 14 is occurred efficiently, and therefore, heat is efficiently discharged.Such simple structure of the rings-steel traveler device of present example allows the slip of rotation and steel traveler 12 by utilizing bobbin to increase radiating effect.
Present invention will provide following effect.
(1) rings-steel traveler device of ring ingot shape spinning machine comprises multiple recess 14, and in its surface slidingly contacted with steel traveler 12 being at least formed in rings 11, and each recess has circular open and spherical curvature inner surface.Therefore, utilize simple structure to pass through to use the rotation of bobbin and the slip of steel traveler 12, can radiating effect be increased.
(2) formation that the opening radius had is equal to or greater than the recess 14 of the depth H of recess 14 allows the air-flow 15 produced by the rotation of bobbin and the slip of steel traveler 12 to smoothly pass in recess 14.
(3) recess 14 formed by bulb-type recessed surface is easily formed, and allow smooth flow of gas 15 by recess 14.
(4) because the position of steel traveler 12 and catch up with (chasing) of bobbin move, the air-flow around rings 11 is inconstant.But, there is bulb-type recessed inner surface and therefore not the directive recess of tool 14 allow under any airflow state heat efficiently discharged.
Present invention is not limited to above-described embodiment, but it can be modified by different way, as illustrated below.
Recess 14 can so be arranged, thus its surface is formed by the recessed surface connected continuously glossily of the ball of different-diameter.
Recess 14 needs not be bulb-type recessed, as long as it has basic curved surface.Such as, recess 14 can have the shape formed by ellipse of revolution or parabola.
The surface of recess 14 can need not to be smooth, but it can be Slight undulations, and its surface area due to increase can produce the radiating effect more expected.
Recess 14 need not be formed by the curved surface simply caved in, but it can by its recess with heave the curved surface that portion smooth is connected continuously and formed.
The recess of different size can be formed.
Recess 14 need not separate with well-balanced interval (the unified distance between two adjacent dimple 14), but they can arrange in a random basis.
The cross section of the flange 11A of the rings 11 of rings-steel traveler device needs not be T-shaped.Such as, the cross section of flange 11A can be formed slopely, as shown in Figure 4.In this case, steel traveler 12 should be formed the flange 11A mating inclination, as shown in Figure 4.
Recess 14 is not necessarily formed by laser, but can be formed by different chemistry or physical method, such as microetch or bead.
Recess 14 can be formed in the steel traveler 12 of rings-steel traveler device, instead of in rings 11.But in this case, the quantity of recess obviously reduces.In order to better draught effect, recess should be preferably formed in rings 11.
Rings-steel traveler device is applicable to any spinning machine with rings, such as ring doubling frame.
