In the process of high-speed sewing, the friction of eedle and spur head and collision are unavoidable.If materials'use is improper or heat treatment hardness infiltration layer is bad, the service life of shuttle race all can be affected.
Utility model content
The purpose of this utility model is the rotating shuttle for sewing machine providing a kind of long service life, low energy consumption, high effect, low cost.
For solving the problems of the technologies described above, the utility model provides a kind of rotating shuttle for sewing machine, comprise shuttle race cap and shuttle race circle, the material of described shuttle race cap and shuttle race circle is spheroidal graphite cast-iron, described shuttle race snare is located in shuttle race cap, and the bottom centre of described shuttle race cap is provided with newel, and newel extends back along described shuttle race cap axis direction, be provided with the space holding sewing thread in described newel, bottom described shuttle race circle, be provided with through hole accordingly with described center column; Described shuttle race cap is provided with spur, and the hardness of described spur is greater than the hardness of shuttle race bed body.
The utility model improves to be had, and the lower edges of described shuttle race circle is equipped with groove; The edge part of described shuttle race circle is provided with the opening for installing draw point.
The utility model improves to be had, and the through hole of described shuttle race circle is provided with and is fixedly connected with shuttle race circle and is the lead of hollow structure, and described lead extends forward along described shuttle race cap axial direction.
The utility model improves to be had, and the sidewall of described guiding cylinder offers gathering sill.
The utility model improves to be had, and described spur is carburizing steel material carved piece.
The beneficial effects of the utility model are specific as follows: the rotating shuttle for sewing machine of new structure, when running up coefficient of friction very low energy reduce due to fricative heat, heat is caused to be that oil can ooze out from the inside in friction, substantially increase service life, low energy consumption, high effect, low cost, and the length of sewing thread and width are by the restriction in shuttle race space, sewing thread long as far as possible can be used on shuttle race, reduce the replacing number of times of rotating shuttle for sewing machine coil, improve sewing efficiency, spur part adopts high hardness material, improve the anti-wear performance of spur part, extend the service life of shuttle race, be conducive to cost-saving, and parts processing reduces the difficulty of one processing, improve production.

Label declaration: 1-shuttle race cap; 2-shuttle race circle; 3-newel; 4-spur; 5-lead; 6-gathering sill.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to accompanying drawing 1, the utility model shown in accompanying drawing provides a kind of rotating shuttle for sewing machine, comprise shuttle race cap 1 and shuttle race circle 2, the material of described shuttle race cap 1 and shuttle race circle 2 is spheroidal graphite cast-iron, described shuttle race circle 2 is set in shuttle race cap 1, and the bottom centre of described shuttle race cap 1 is provided with newel 3, and newel 3 extends back along described shuttle race cap 1 axis direction, be provided with the space holding sewing thread in described newel 3, bottom described shuttle race circle 2, be provided with through hole accordingly with described newel 3 body;
Described shuttle race cap 1 is provided with spur 4, and the hardness of described spur 4 is greater than the hardness of shuttle race bed body.
The material that the shuttle race device of new structure adopts is spheroidal graphite cast-iron, substituted for original casting pig, has the following advantages:
1, spheroidal graphite cast-iron has higher tensile strength and bending fatigue limit, also has quite good plasticity and toughness, when sewing machine shuttle runs up coefficient of friction very low energy reduce due to fricative heat.
2, Nodular Iron structure is spherical, can infiltrate grease in gap, when friction causes heat to be that oil can ooze out from the inside, substantially increases service life.
3, this inside parts slideway is through Quenching Treatment, has accomplished low energy consumption for HRC50 °-60 °, high effect, low cost, long life.
By arranging newel 3 at shuttle race cap 1 and arrange through hole accordingly with newel 3 on shuttle race circle 2, sewing thread can pass from the space in newel 3, and penetrate in shuttle race circle 2 for sewing, therefore, coil of sewing can directly be sleeved on newel 3, because the space in newel 3 can be larger, therefore the length of coil of sewing and width are by the restriction in shuttle race space, sewing thread long as far as possible can be used on shuttle race, reduce the replacing number of times of rotating shuttle for sewing machine coil, improve sewing efficiency.
Further, the through hole of described shuttle race circle 2 is provided with and is fixedly connected with shuttle race circle 2 and is the lead 5 of hollow structure, and described lead 5 extends forward along described shuttle race cap 1 axial direction, preferably, the sidewall of described lead 5 offers gathering sill 6.By arranging lead 5 body in shuttle race circle 2, sewing thread is used for sewing through drawing shuttle race through lead 5 body after newel 3, can prevent sewing thread from tiing a knot in shuttle race circle 2, is beneficial to sewing thread guiding.
Shuttle race bed body and spur 4 adopt the material of different hardness, reduce production cost, the whole service life and the production efficiency that improve shuttle race are high, further, described spur 4 is carburizing steel material carved piece, improves the anti-wear performance of spur 4 part, extend the service life of shuttle race, be conducive to cost-saving, and parts processing reduce the difficulty of one processing, improves productivity ratio.
In the present embodiment, the lower edges of described shuttle race circle 2 is equipped with groove; The edge part of described shuttle race circle 2 is provided with the opening for installing draw point, utilizes shuttle race circle 2 to fix draw point, and its fixed effect is better, easy to use, reduces production cost.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
