Description
Technical field
The present invention relates to a kind of spring, more particularly to a kind of wave forms spring for carrying protection.
Background technology
Wavy spring is the spring element on sheet metal annulus with several sinusoidal undulations, the ripple of each model
Shape spring has an intrinsic limited compression height.Under external force, when wavy spring by actual compression to being higher than or wait
When intrinsic limited compression height, wavy spring happens is that elastic deformation, that is, remove after external force, wavy spring can return to original
The state come；Under external force, if a wavy spring by actual compression to less than intrinsic limited compression height when, waveform
Spring will be permanently deformed, that is, remove after external force, wavy spring can not return to original state.In actual use, due to
Accidental factor causes wavy spring to be permanently deformed, and elastic force during working condition will be caused significantly to be less than specified force value, can make phase
Close structure to occur pretension deficiency, the major accidents such as piston can not be promoted, wavy spring safety coefficient is relatively low, service life is not long.
The content of the invention
In view of this, the technical problems to be solved by the invention are：A kind of safety coefficient height, long lifespan, band protection are provided
The wavy spring of compression height, makes it protect compression height greater than or equal to its intrinsic limited compression height.
In order to achieve the above object, the present invention adopts the following technical scheme that to realize：
A kind of wavy spring, comprising wavy spring body, wavy spring body is provided with multiple crests and trough, the ripple
Shape spring body is provided with convex body in trough concave surface center.The convex body increases by one in the concave surface center of wavy spring body trough
Surely thickness is protected, makes it protect thickness to protect compression height greater than or equal to intrinsic limited compression height, and less than waveform bullet
Spring operating compression height, i.e., less than the compression height in wavy spring real work.
Preferably, the wavy spring body is provided with opening, the opening is located at trough.
Preferably, the convex body is shaped in wavy spring body, the concave direction of opening side trough is anti-
Convex body is formed to bending；Increase protection thickness by the way of the concave direction inverse bending near wavy spring trough opening,
I.e. compression height is protected in increase.
Preferably, the convex body welding or bonding are connected to the concave surface of the spring body trough of opening side；Using
Increase protection thickness in the mode such as the welding of wavy spring trough concave direction immediate vicinity or bonding, that is, protect compression height.
Preferably, the wavy spring body is closed loop spring body, the convex body welding or bonding are connected to wherein
The concave surface of one trough；Wavy spring body can be increased in trough concave direction immediate vicinity using the mode such as welding or bonding
Thickness is protected, i.e. increase protection compression height
Wavy spring is positioned in parallel upper lower platen, and lower platen is fixed, using in compression process when top board compress
During to protection compression height, under accidental extreme case, top board can not continue down to compress, and effectively protect waveform
Spring, prevents wavy spring to be permanently deformed.
As shown from the above technical solution, the beneficial effects of the invention are as follows：
Compared with prior art, the present invention passes through in the certain protection thickness of trough concave direction immediate vicinity increase, it is to avoid ripple
Shape spring is compressed to the situation generation less than intrinsic limited compression height, prevents wavy spring to be permanently deformed, so as to carry
The high safety coefficient of wavy spring, the service life for enhancing wavy spring.

Embodiment
In order that those skilled in the art can be further understood that the feature and technology contents of the present invention, referring to following has
Close detailed description of the invention and accompanying drawing.
Embodiment one
As shown in Fig. 1, Fig. 1-1, a kind of wavy spring, comprising wavy spring body 1, wavy spring body 1 is provided with more
Individual crest and trough, wavy spring body 1 are convex body 3 provided with protection structure in trough concave surface center, and convex body 3 is welded to connect solid
At the concave surface 2 of the spring body trough of the side of opening 4；L is A/F, and t0 is the material thickness of wavy spring body 1,
T1 is increased thickness, and t2 is the protection compression height for protecting thickness to be wavy spring.T2 is more than or equal to consolidating for wavy spring
There is limited compression height, while the operating compression height of wavy spring need to be less than.
Embodiment two
As shown in Fig. 2, Fig. 2-1, convex body 3 is shaped in wavy spring body 1, the direction of concave surface 2 for the 4 side troughs that are open
Inverse bending formation convex body 3；The direction inverse bending increase protection thickness of concave surface 2 near trough opening 4 of wavy spring body 1.
T0' is wavy spring bulk material thickness, and t1' is increased thickness, and t2' compresses high for the protection that protection thickness is wavy spring
Degree.T2' is more than or equal to the intrinsic limited compression height of wavy spring, while need to be less than the operating compression height of wavy spring.
Embodiment three
As shown in Fig. 3, Fig. 3-1, wavy spring body 1 is closed loop spring body, and convex body 3 is welded to connect in one of ripple
At the concave surface 2 of paddy；Wavy spring body 1 using welding manner increase protection thickness, that is, increases in trough concave direction immediate vicinity
Plus protection compression height；T0 " is wavy spring bulk material thickness, and t1 " is increased thickness, and t2 " is waveform for protection thickness
The protection compression height of spring.T2 " is more than or equal to the intrinsic limited compression height of wavy spring, while need to be less than wavy spring
Operating compression height.
As shown in figure 4, the structural representation of the wavy spring for existing prior art, wavy spring body 1 is protected without any
Protection structure, using central, because accidental factor causes wavy spring to be permanently deformed, when will cause working condition, elastic force is significantly
Less than specified force value, dependency structure can occurs, and pretension is not enough, can not promote the major accidents such as piston, causes very big safety hidden
Suffer from.
Implement structural representation as shown in figure 5, being installed for wavy spring, wavy spring body 1 is placed in lower platen 6 and upper pressure
In plate 5.In compression process, lower platen 6 and the keeping parallelism of top board 5, lower platen 6 are fixed, and top board 5 is moved down.When upper
Pressing plate 5 touch protection structure i.e. the upper surface of convex body 3 when, be between top board 5, wavy spring body 1 and lower platen 6 rigidity
Contact, top board 5 can not continue to move down, so as to avoid excess compression wavy spring.
