Abstract
The utility model relates to an improved pressure spring which comprises a big spiral spring. A top plate is welded on the big spiral spring, the top plate is in a circular shape, and at least three small spiral springs are evenly welded on the top plate in the circumferential direction. The improved pressure spring can be adapted to external load of large area and large pressure.
Description
Technical field
The utility model relates to the spring field, relates in particular to a kind of modified model Compress Spring.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to carry out work, generally with spring steel, makes.Impact or shake, store up the size of energy, measuring force etc. in order to motion, the mitigation of controlling parts, be widely used in machine, instrument.Spring is an accumulator just, and it has the function of stored energy, but can not discharge energy at leisure, realize that this function of slow release should lean on " spring+big speed ratio mechanism " to realize, is common in mechanical watch.Spring had just been applied very early, and the bow in ancient times and crossbow are exactly two kinds of sensu lato springs.By stressed character, spring can be divided into extension spring, Compress Spring, torsion spring and flexural spring, belleville spring, annular spring, leaf spring, helical spring, valute spring and torsion bar spring etc. can be divided into by shape, by working process, cold coiling spring and hot coiling spring can be divided into.The common cylinder spring is simple owing to manufacturing, and can make various types according to the stand under load situation, simple in structure, therefore most widely used.In general the manufactured materials of spring should have high limit of elasticity, fatigue limit, impact toughness and good heat treatment performance etc., and commonly used have carbon spring steel, alloy spring steel, rustproof spring steel and Cuprum alloy, nickel alloy and a rubber etc.The manufacture method of spring has cold coiling method and hot rolling method.Some spring also will be suppressed or shot blast after making, and can improve the bearing capacity of spring.
Compress Spring is the helical spring that bears pressure, it is circular that its material section used mostly is, also useful rectangle and multiply steel are entangled and are rolled, spring is generally equal pitch, the shape of spring has: cylindrical, conical, camber and middle concave and a small amount of non-circular etc., and to adapt to the demand in the different operating situation.Between the circle of Compress Spring and circle, certain gap is arranged, when being subject to external load, the spring contraction distortion, store energy of deformation.But existing spring shape not too adapts to large size, large pressure external load.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of modified model Compress Spring is provided.
The utility model is to be achieved through the following technical solutions:
A kind of modified model Compress Spring, comprise the king bolt spring, on described king bolt spring, is welded with top board, and described top board is rounded, and described top board has at least three small coil springs along circumferential uniform welding.
Further, the thickness of described circular top plate is 3-6mm.
Further, the diameter of described circular top plate is greater than the outermost diameter of king bolt spring.
Further, the outermost diameter of described king bolt spring be the small coil springs outermost diameter 2.5-3.5 doubly.
Further, the bottom surface of the end face of described small coil springs and king bolt spring is plane and is parallel to each other.
Compared with prior art, the beneficial effects of the utility model are: the utility model can adapt to the external load of large size, large pressure.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of modified model Compress Spring, comprise king bolt spring 1, be welded with top board 2 on described king bolt spring 1, described top board 2 is rounded, described top board 2 has at least three small coil springs 3 along circumferential uniform welding, the employing welding method is one-body molded, makes its structure firm, can adapt to the external load of large size, large pressure.
The thickness of described circular top plate 2 is 3-6mm, and the diameter of described circular top plate 2 is greater than the outermost diameter of king bolt spring 1, and the outermost diameter of described king bolt spring 1 is 2.5-3.5 times of small coil springs 3 outermost diameter.
The bottom surface of the end face of described small coil springs 3 and king bolt spring 1 is plane and is parallel to each other.
Be set to plane by end face and bottom surface, can be stable while making spring put stop, facilitate putting and transporting of spring, also has more aesthetic property simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
