A kind of arc compression spring, include multiple turns of camber arrangement, in the camber line of the arc compression spring
Direction, is respectively provided with contact plane at left and right sides of the turn, between two contact planes of the turn away from
From the thickness for the turn, the direction of the outer arc from the inner arc of the arc compression spring to the arc compression spring
On, the thickness of the turn gradually increases.
Preferably, during the arc compression spring doubling-up, the turn is in the inner arc of the arc compression spring and outer
Part at arc closes up simultaneously.
Preferably, the cross sectional shape of the turn is oblate, two contact planes of the both sides of the turn and institute
The intersecting lens for stating section forms two oblate straight flanges.
Preferably, the cross sectional shape of the turn is rectangle, two contact planes of the both sides of the turn with
The intersecting lens in the section forms rectangular two opposite side.
Present invention also offers a kind of wind spring equipment, including flatting mill and spring coiling machine, the flatting mill can be adjusted periodically
Save flattening amount, on the direction for making the outer arc from the inner arc of the arc compression spring to the arc compression spring, the spring
The thickness of circle gradually increases.
It can be seen from the above technical proposal that the left and right sides of the turn in arc compression spring in the present invention has
There is a contact plane, the distance between two contact planes are the thickness of turn, from the inner arc of arc compression spring to outer arc
Direction on, the thickness of turn gradually increases, be arranged such turn at inner arc when being partially closed, have it is more its
It is partially closed contact, so that the contact area increase between turn, so that arc compression spring is in impact acceleration operating mode
When, there are enough contact surfaces to disperse stress, so that it is guaranteed that the steady operation of arc compression spring.In addition, the thickness of turn
Reduce because of flattening, so as to reduce space-consuming, increase the compression travel of arc compression spring, be conveniently adjusted arc pressure
The rigidity of contracting spring, has widened application.

Embodiment
The invention provides a kind of arc compression spring, the arc compression spring when by impact acceleration its turn it
Between contact area it is sufficiently large, reliability is high, disclosure satisfy that the demand of impact acceleration occasion.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only the part of the embodiment of the present invention, rather than whole embodiments.Base
In embodiments of the invention, those of ordinary skill in the art obtained on the premise of creative work is not made it is all its
Its embodiment, belongs to the scope of protection of the invention.
In an of the invention specific embodiment, arc compression spring 1 includes multiple turns 11, and multiple turns 11 are into arc
Line is arranged.In the arc direction of arc compression spring 1, the left and right sides of turn 11 is respectively provided with contact plane 10, is respectively a left side
Contact plane and right contact plane, as shown in Figure 2, the distance between left contact plane and right contact plane are turn
Thickness.On direction from the inner arc of arc compression spring to outer arc, the thickness of turn gradually increases, and is arranged such turn and exists
At inner arc when being partially closed, have more other parts and close up contact so that between turn contact area increase,
So that arc compression spring has enough contact surfaces to disperse stress in impact acceleration operating mode, so that it is guaranteed that arc compresses bullet
The steady operation of spring.In addition, the thickness of turn in the present invention reduces because of flattening, so as to reduce space-consuming,
The compression travel of arc compression spring is increased, the rigidity of arc compression spring is conveniently adjusted, has widened application.
In an of the invention specific embodiment, by optimal design-aside in nature the thickness of turn 11 and adjacent
Two turns 11 between gap, to reach in arc 1 doubling-up of compression spring, turn is in arc compression spring
Part at arc and outer arc closes up simultaneously, refer to accompanying drawing 3.Bullet part of the turn 11 at inner arc and outer arc closes up simultaneously when
Contact area between spring coil 11 is maximum, reliability highest.
In a specific embodiment of the invention, the cross sectional shape of turn 11 is oblate.The contact of the both sides of turn 11
Plane 10 and the intersecting lens in the section form two oblate straight flanges.Oblate compression=1-D/C, wherein D are oblate two
The distance between straight flange, C are oblate place diameter of a circle.From the inner arc of arc compression spring 1 to the outer arc of arc compression spring 1
Direction on, the distance between contact plane 10 of the both sides of turn 11 gradually increase, i.e., D is increasing, then compression is got over
Come smaller.Section of the turn 11 at inner arc can be arranged to oblate, the section at outer arc is arranged to round, refer to accompanying drawing
1 and accompanying drawing 3.
In an of the invention specific embodiment, the cross sectional shape of turn 11 can also be rectangle, the two of turn 11
Two contact planes 10 of side form rectangular two opposite side with the intersecting lens in section.From the inner arc of arc compression spring 1 to
On the direction of the outer arc of arc compression spring 1, the distance between rectangular described two opposite side gradually increase,
Present invention also offers a kind of wind spring equipment, including flatting mill and spring coiling machine.Flatting mill being capable of periodic adjustment pressure
Flat amount, on the direction for making the outer arc from the inner arc of arc compression spring to arc compression spring, the contact of the both sides of turn is put down
The distance between face 10 gradually increases.In other words, flatting mill and spring coiling machine cooperating, make flattening amount of the turn at inner arc
Maximum, the flattening amount at outer arc are minimum.The turn of variable cross-section can be produced using the wind spring equipment in the present invention, finally
Obtain variable cross-section arc compression spring.
The described above of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.It is right
