Abstract
The invention provides a torsion spring for shoes, which comprises a segmental spring strip. The torsion spring is characterized in that: two ends of the spring strip are coiled upwards to form hook shapes which are favorable for hinging at corresponding parts of a sole, the spring is of an upward arc from one end to the other end, and the spring is rotated and coiled twice at the symmetrical positions of the arc top. The torsion spring has a simple structure and good elasticity, and can effectively play a role in buffering and reduce sport injury; and the forming process is simple and has high production efficiency.
Description
Technical field
The present invention relates to a kind of footwear with torsional mode spring and moulding process thereof, be applied to footwear and already produce, belong to the spring field.
Background technique
Footwear are requisite daily necessitiess during we live, and in movement process, the effect of sole is obvious especially especially.Because we are in life motion, for example walking, climb the mountain, play ball etc. when movable, can make our bone produce bump, friction, thereby damage our bone joint, sole damping, buffer function are just most important.Thereby, are research purposes of the present invention at the problems referred to above.
Summary of the invention
One of purpose of the present invention is that a kind of footwear torsional mode spring will be provided, and this spring structure is simple, and elastic force is good, and cushioning effect is good.
The invention is characterized in: a kind of footwear torsional mode spring, comprise the section of one-tenth spring, it is characterized in that: volume and one-tenth hook-type on the described spring two end part, be placed on the sole corresponding site in order to hinged, described spring one end to the other end becomes to go up arc, and symmetry twice rotation in place reeled on the arc top.
Another object of the present invention is that a kind of footwear torsional mode spring forming technology will be provided, and this manufacturing process is simple, and the shaping efficiency height is easy and simple to handle.
Another feature of the present invention is: a kind of footwear is characterized in that with torsional mode spring forming technology, carry out as follows:
A. select the SUS304 stainless steel material for use, and to select diameter for use be 2.5mm;
B. send into the automatic spring wind-roll-forming;
C. carry out tempering heat treatment, adopting temperature is 380 ° ± 15 °, temper time 30m;
D. temper profiled member is carried out shot blast, shot-peening time 30-45m;
E. again the profiled member after the shot blast is carried out tempering heat treatment, adopting temperature is 240 ° ± 15 °, temper time 30m;
F. carry out cleaning process, decontamination;
G. pack.
Advantage of the present invention: the present invention is simple in structure, and elastic force is good, can effectively play buffer function, reduce injury gained in sports, and moulding process is simple, the manufacturing efficiency height.
Description of drawings
Fig. 1 is an embodiment of the invention structural front view.
Fig. 2 is an embodiment of the invention structure plan view.
Embodiment
With reference to figure 1 and Fig. 2, a kind of footwear torsional mode spring, comprise the section of one-tenth spring 1, the last volume of described spring two end part 1-1,1-2 also becomes hook-type, be placed on the sole corresponding site in order to hinged, described spring one end 1-1 arc to the other end 1-2 one-tenth, and reel in twice rotation of the symmetry 1-3 of place of arc top, the race diameter that is wound into the circle place reaches 8.6mm.
Above-mentioned rotation is reeled and is adopted dextrorotation to roll, and rotation coiling axis 2 is parallel with end hook oblique crank Z line 3.。
Above-mentioned one-tenth section spring adopts the SUS304 stainless steel material, and to become a section spring to select diameter for use be 2.5mm.
A kind of footwear torsional mode spring forming technology, carry out as follows:
A. select the SUS304 stainless steel material for use, and to select diameter for use be 2.5mm;
B. send into the automatic spring wind-roll-forming;
C. carry out tempering heat treatment, adopting temperature is 380 ° ± 15 °, temper time 30m;
D. temper profiled member is carried out shot blast, shot-peening time 30-45m;
E. again the profiled member after the shot blast is carried out tempering heat treatment, adopting temperature is 240 ° ± 15 °, temper time 30m;
F. carry out cleaning process, decontamination;
G. pack.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
