Abstract
nullThe utility model discloses the spring Welding Structure of a kind of pair of M type，Mainly include double M type butterfly spring and rigid casing，The most double M type butterfly springs are formed by a spring steel coiling，All the time there is the interface of a docking，Described rigid casing two ends have hole，And as the external diameter of the spring steel of the diameter in hole M type butterfly spring double with coiling，Two ends of double M type butterfly springs may be inserted in the hole at rigid casing two ends，Then utilize hydraulic press by rigid casing Pressing Deformation，Two ends of double M type butterfly springs are firmly linked together，Two ends of traditional double M type butterfly springs are all that the mode using common welding links together，Usually there will be welding junction dislocation，Cause welded section too small，When double M type butterfly spring left and right discontinuity，The Displacement-deformation bringing both sides is different，Cause being caused double M type butterfly spring to fracture by shearing force at welding junction.
Description
Technical field
This utility model belongs to spring processing and manufacturing technical field, and specifically, this utility model relates to a kind of pair of M type
Spring Welding Structure.
Background technology
Current double M type butterfly springs are formed by a spring steel coiling, there are the interface of a docking, double M type butterflies all the time
The seam of two ends of butterfly spring is all that the mode using common simple welding links together, and usually there will be welding and connects
Mouth dislocation, causes welded section too small, and when double M type butterfly spring left and right discontinuity, the Displacement-deformation bringing both sides is different,
Causing receiving at welding junction shearing force causes double M type butterfly spring to fracture, and double M type butterfly spring is repeatedly stress constantly becomes
The object of shape, simple welding or welding junction dislocation, the life-span causing a large amount of double M type butterfly spring is the shortest, need to often change, dimension
Protect cost virtually to be increased, and waste social resources.
Summary of the invention
This utility model provides the spring Welding Structure of a kind of pair of M type, it is therefore an objective to solve the welding junction of double M type butterfly spring
Place's welding dislocation, discontinuity, frangibility, cause the problem that the life-span of double M type butterfly spring is the shortest.
To achieve these goals, the technical scheme that this utility model is taked is: the spring Welding Structure of a kind of pair of M type,
Mainly include double M type butterfly spring and rigid casing, it is characterised in that: double M type butterfly springs are formed by a spring steel coiling, and begin
There is a mating interface eventually.
Preferably, described rigid casing two ends have outside hole, and the spring steel of the diameter in hole M type butterfly spring double with coiling
Footpath is identical.
Preferably, two ends of described pair of M type butterfly spring may be inserted in the hole at rigid casing two ends, then uses hydraulic pressure
Two ends of double M type butterfly springs, by rigid casing Pressing Deformation, are firmly linked together by punch press.
Preferably, described rigid casing is that the rigid material with certain ductility and structural strength is made.
This utility model is used to solve at the welding junction of double M type butterfly spring to weld dislocation, discontinuity, easy to break
Disconnected, cause the problem that the life-span of double M type butterfly spring is the shortest, for solving the problems referred to above, the connected mode of docking port has been done brand-new
Design, uses above technical scheme to provide the benefit that: makes into traditional welding manner to connect with rigid casing, then uses liquid
The two of seam ends by rigid casing Pressing Deformation, are linked together by pressure punch press firmly, it is to avoid welding brings
The generation of the welding inconsistent phenomenon at welding junction, uses rigid casing to connect simultaneously, because both sides Displacement-deformation is different, and will welding
Seam pad, by shearing force, is changed into by shearing force in the length in the hole made on rigid casing, by the stress of shearing force
Point dispersion, effectively prevent double M type butterfly spring and fractures at pad and scrap, improve the service life of double M type butterfly spring.

Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, detailed description of the invention of the present utility model is made the most in detail
Thin explanation, it is therefore an objective to help those skilled in the art design of the present utility model, technical scheme are had more complete, accurately and
Deep understanding, and contribute to its enforcement.
As shown in Figures 1 to 4, this utility model is the spring Welding Structure of a kind of pair of M type, and this utility model is used to solve
Welding dislocation, discontinuity, frangibility at the welding junction of the most double M type butterfly springs, the life-span causing double M type butterfly spring is the shortest
Problem.
Specifically, as shown in Figures 1 to 4, the spring Welding Structure of a kind of pair of M type, mainly include double M type butterfly spring 1
With rigid casing 2, the most double M type butterfly springs 1 are formed by a spring steel coiling, all the time exist a mating interface, described just
Property sleeve pipe 2 two ends have a hole, and the external diameter of the spring steel of the diameter in hole M type butterfly spring 1 double with coiling is identical, when double M type butterflies
Two ends of butterfly spring 1 insert the Kong Zhonghou at rigid casing 2 two ends, then utilize hydraulic press by rigid casing 2 Pressing Deformation,
Double M type butterfly springs 1 are fixed together firmly by the deformation utilizing rigid casing 2 at seam, it is to avoid the weldering that welding brings
The generation of the welding inconsistent phenomenon at connection interface, uses rigid casing 2 to connect simultaneously, because both sides Displacement-deformation is different, and will welding
Seam pad, by shearing force, is changed into by shearing force in the length making the hole on rigid casing 2, by the stress of shearing force
Point dispersion, effectively prevent double M type butterfly spring 1 and fractures at pad and scrap, improve the service life of double M type butterfly spring 1.
Above in association with accompanying drawing, this utility model is exemplarily described, it is clear that this utility model implements not
Limited by aforesaid way, as long as have employed the various unsubstantialities that method of the present utility model design is carried out with technical scheme
Improvement；Or the most improved, above-mentioned design of the present utility model and technical scheme are directly applied to other occasion, all at this
Within the protection domain of utility model.
