Abstract
The utility model discloses a combined light steel spinning cup which is a key component used on a rotator spinning machine. The combined light steel spinning cup is formed by the combination of a drive rod 1, a supporting seat 2, a rotating cup 3, a buckling rotating cup 3 and a spring pressing sheet 4, wherein the rotating cup and the buckling rotating cup are formed by punching thin steel boards; the spring pressing sheet enables the rotating cup and the buckling rotating cup to rotate simultaneously. The spinning cup has the advantages of material saving, easy manufacture, low investment in processing equipment, good quality of yarn produced by the spinning machine, and long service life.
Description
The utility model belongs to the key component on a kind of open-end spinning frame, and it directly influences spinning efficiency and quality.
Rotor spinning (having another name called open-end spinning) is modern novel spinning technology.Because its spinning efficiency height, quality is good, and can make characteristics such as raw material with shoddy cotton, is applied rapidly at home.Cup be exactly this equipment key component, it directly influences spinning efficiency and quality.The used revolving cup of present frame both domestic and external (on the cup main); all use aluminium (steel) material monolithic car system to form; constitute the monoblock type cup then on the ramming stem; this cup has different inner chamber profile (fibre-condensing groove); the luminosity of this profile requires all very strict from luminosity and the whole pendulum of compiling; so adopt Digit Control Machine Tool processing mostly; also there is minority to process with omnipotent fine turning lathe; no matter by which kind of equipment processing; efficient is all very low; the revolving cup of domestic production at present generally is to be made by the aluminium car in addition; but in order to prevent of the pollution of aluminium ash to yarn; so inner cavity surface must be handled, plating is with protective layer, yet this protective finish ABRASION RESISTANCE is still undesirable; bond strength is also bad sometimes, easily peels off; influence the working life of revolving cup.
The purpose of this utility model is a kind of combined type light section cup of design, replaces all-in-one-piece cup to be used to overcome deficiency of the prior art with (part).
The utility model is to realize with following technical pattern: it comprises that drive link 1, revolving cup 3, special feature are that to be provided with bearing 2 on drive link 1 be interference fit with drive link 1, the end of the revolving cup 3 that is stamped to form by book shaped steel plate and an end of bearing are close to, have a butterfly spring compressing tablet 4 also to be interference fit with drive link 1, the axial force of utilizing camber of spring to produce compresses revolving cup 3 on bearing 2.
Advantage of the present utility model: this cup is easy to manufacture, and working (machining) efficiency is about 3-5 times of existing monoblock type cup; This cup in use yarn quality is good, does technical indicators such as CV% value, slubbing, details and cotton knot at bar and all is better than (equaling) homemade whole shape cup; Long service life is existing more than 5 times of cup; Low equipment investment, the revolving cup of producing in the utility model only needs common apparatus such as hydraulic press, punch press, polishing machine, and produces revolving cup in the whole shape cup except that hydraulic press, must be with accurate universal lathe or numerically controlled lathe, the latter invests than the former and exceeds more than 5 times.
Description of drawings of the present utility model:
Fig. 1 partly cuts open front view for the whole shape of the utility model.
Fig. 2 is a revolving cup of the present utility model operation schematic diagram in force: blanking (2) revolving cup stretching pre-profiling, (3) revolving cup final molding of (1) expression revolving cup
In conjunction with the accompanying drawings structural principle of the present utility model and enforcement thereof are described further:
Shown in Figure 1: in addition form by four, drive link 1 is transmitting torque by parts for this cup, by belt bar 1 is driven (40,000-60,000 rev/mins) rotation at a high speed, thus make revolving cup etc. other parts rotate together in addition, the revolving cup inner chamber is negative pressure, with the cotton fiber that sucks, slip into the fibre-condensing groove along wall and twist into yarn and extract, finish spinning process out.Revolving cup 3 is the thick 0.8F plate stamping spare of 0.8mm, join with bar 1 to be associated with certain tightness, but because thickness is too little, the frictional force that this tightness produces under high speed rotating can not guarantee that revolving cup and bar 1 keep stable synchronous rotation; Therefore must utilize bearing 2 and spring pressuring plate 4 to choke revolving cup 3 at the pressure that axially produces, to reach stable purpose of rotating synchronously, compressing tablet 4 is a kind of butterfly spring sheets, is interference fit with bar 1, the axial force of utilizing the distortion of axial compression rear spring to produce compresses revolving cup on bearing 2, and bearing 2 is an interference fit with bar 1 equally.
The key of this cup is the processing of revolving cup 3, and as shown in Figure 2, this is a kind of sheet metal component, and at first blanking is made through master operations such as punching press, stretching, extrusion modlings again.The moulding of inner chamber profile is to excise overlap on the basis of stretching, pre-profiling.Keep accurate computed altitude, extrusion molding in the upper and lower mould of similar sealing with surfaces externally and internally polishing, bore hole, carries out antirust Wear-resistant Treatment at last then.
