Abstract
The utility model provides a spinning groove drum suitable for superplastic forming, which comprises a barrel body provided with a U-shaped yarn-guiding groove, an upper cover, a bottom cover and a sleeve arranged in the barrel body, wherein the upper cover and the bottom cover are correspondingly installed at the upper end and the lower end of the barrel body, and the sleeve is installed in a hole of the upper cover and a hole of the bottom cover. The outer side of one end of the sleeve is provided with a triangular ring groove, and the outer side of the other end of the sleeve is provided with a through hole and a boss. The spinning groove drum suitable for superplastic forming has the advantages of resolving the problem that a bearing support arranged in the groove drum can not be processed in superplasticity forming mode, and being light in weight, sufficient in intensity and rigidity, bright and clean in surface, high in precision, good in consistency, simple in formed equipment, small in investment, short in production cycle and easy in thread winding.
Description
Technical field
The utility model relates to the technical field that is used for the groove drum on the weaving loom, refers in particular to a kind of weaving groove drum of suitable superplastic forming.
Background technology
The groove drum profile of present textile machines has conical butt and cylindrical; According to different driving methods; Roughly be divided into two kinds of structures: a kind of is that the groove drum two-port directly cooperates transmission with transmission shaft, is the hollow structure that stainless steel material is processed like the disclosed groove drum structure of CN2132726Y; CN1086429A discloses a kind of employing superplastic grooved alloy drum and manufacturing process and device.The weak point that above-mentioned type of drive exists is that driving torque is bigger, and rotating speed is low.Another kind of drive mechanism is that the midway location of groove drum has bearing seat, like the groove drum structure on Japan's " field, village " bobbin-winding machine, the method for cylindrical shell with covers and bearing seat employing casting processing is processed as one; The advantage of this structure is that moment of torsion is little, and power is little, and rotating speed is high; Working stability, but its weak point is a too complicacy of contour structures, and casting processing groove drum surface is more coarse; Precision is low, must replenish processing through high-precision numerical control machine, and cost is higher.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of simple and reliable for structure, is fit to the weaving groove drum of superplastic forming.
For realizing above-mentioned purpose; The technical scheme that the utility model provided is: a kind of weaving groove drum of suitable superplastic forming; It includes cylindrical shell, loam cake, the bottom of U-shaped guide groove and places the sleeve in the cylindrical shell; Wherein, loam cake and bottom correspondence are installed in the two ends up and down of cylindrical shell, and sleeve is installed in the hole of loam cake and bottom; The one end outside of described sleeve is provided with the triangle annular groove, and its other end outside is provided with through hole and boss.
The hard-wired contact surface of described loam cake and bottom and cylindrical shell inboard is separately installed with steady ring.
The external diameter of described sleeve is circular.
There are 45 ° of chamferings at described sleeve two ends.
The utility model is after having adopted such scheme, and its great advantage has been to solve the difficult problem that superplastic forming can not processed tape spool bearing in the middle of the groove drum, and groove drum is in light weight; Enough strength and stiffness are arranged, any surface finish, precision is high; High conformity, and former is simple, invests little; With short production cycle, be easy to reach the standard grade.
Description of drawings
Fig. 1 is the scheme drawing of the utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
Shown in accompanying drawing 1; The described weaving groove drum of present embodiment; It includes cylindrical shell 1, loam cake 2, the bottom 3 of U-shaped guide groove and places the circular sleeve 4 in the cylindrical shell 1, and wherein, loam cake 2 and bottom 3 correspondences are installed in the two ends up and down of cylindrical shell 1; Circular sleeve 4 is installed in the hole of loam cake 2 and bottom 3, and the circular sleeve 4 of present embodiment uses as the groove drum middle bearing bracket; One end of described circular sleeve 4 outside is provided with triangle annular groove 5, and its other end outside is provided with through hole 6 and boss 7, and there are 45 ° of chamferings at sleeve 4 two ends, and is convenient for assembly.Described loam cake 2 is separately installed with steady ring 8 with bottom 3 and cylindrical shell 1 hard-wired contact surface inboard.The cylindrical shell 1 of present embodiment is realized with sleeve 4 usefulness superplastic forming job operations, also can be used the steel plate it by punch and weld.And the loam cake 2 of present embodiment can adopt the superplastic forming processing technology with bottom 3, also can adopt the processing of casting processing or other common machining method.In a word, the utility model has solved the difficult problem that superplastic forming can not be processed tape spool bearing in the middle of the groove drum, and groove drum is in light weight, enough strength and stiffness are arranged; Any surface finish, precision is high, high conformity, and former is simple; Invest for a short time, with short production cycle, be easy to reach the standard grade.
The above embodiment is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
