Description
Technical field
The invention belongs to compress leaf spring field, and in particular to a kind of compression leaf spring residual stress cancellation element.
Background technique
Supersonic vehicle upper spring part is in addition to applying the spring as made of steel wire wound (referred to as around spring), and there are also by steel
The spring (abbreviation leaf spring) of plate production, leaf spring class part play important work to the normal flight and reliably working of supersonic vehicle
With since leaf spring part material is spring steel, compared with common iron: spring steel material elasticity modulus is generally smaller, therefore plate
Inside parts are inevitably present apparent residual stress after spring forming parts, and the presence of leaf spring inside parts residual stress
Service life and steady operation to part cause to directly affect.
Summary of the invention
The object of the present invention is to provide a kind of compression leaf spring residual stress cancellation elements, solve part after leaf spring forming parts
Inside is inevitably present the problem of apparent residual stress.
The technical solution of the present invention is as follows: a kind of compression leaf spring residual stress cancellation element, it is characterised in that: including bottom plate 3,
Left and right locating piece and before in after three templates, left and right locating piece is separately fixed at bottom plate two sides, and three templates are parallel by screw
It is fixed on bottom plate, between the locating piece of left and right；Former and later two template bottom outsides are equipped with multiple slots；The two sides of middle template
It is equipped with multiple slots；Multiple compression leaf springs are directly plugged in the slot of template, on leaf spring the weight of cover constant weight,
Keep leaf spring compression after a certain period of time, release, disassembly leaf spring.
The utility model has the advantages that the present invention by leaf spring the weight of cover constant weight, keep leaf spring compression after a certain period of time,
Release, disassembly leaf spring, achieve the purpose that convenient, quick elimination leaf spring internal residual stress, ensure that the stabilization of elasticity of plate spring
Property, the effect and function of leaf spring are played, to greatest extent for other similar compression leaf spring residual stress cancellation element design ginsengs
It examines and uses for reference, have immeasurable influence to the normal flight of supersonic vehicle, reliably working and batch production.
Detailed description of the invention
Fig. 1 is leaf spring schematic diagram；
Fig. 2 is main view of the invention
Fig. 3 is the top view of Fig. 2.
Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, a specific embodiment of the invention is made further detailed
Thin description.
The present invention provides a kind of compression leaf spring residual stress cancellation element, including bottom plate 3, left and right locating piece 1,2, it is preceding in after
Three templates 4,5,6, left and right locating piece are fixed by screws in bottom plate two sides respectively, and three templates are fixed in parallel by screw
On bottom plate, between the locating piece of left and right；
Former and later two template bottom outsides are equipped with multiple slots；The two sides of middle template are equipped with multiple slots；
The end of multiple compression leaf springs is plugged in the slot of template；The pluggable compression plate in template two sides positioned at middle part
Spring, positioned at the template of two sides, its outside can compress leaf spring with grafting；Leaf spring part is directly plugged in the slot of device, in plate
After a certain period of time, release, disassembly leaf spring reach and eliminate inside leaf spring for the weight of cover constant weight, the compression of holding leaf spring on spring
The purpose of residual stress.
Locating piece plays position-limiting action, and weight is placed on locating piece, and the height of locating piece should be greater than leaf spring itself most
Big decrement, less than the height of leaf spring.
1) the following attached drawing 1 of plate spring structure form is imitated according to the space structure feature of leaf spring and in view of the production of leaf spring
Rate is intended making the present apparatus with the steel plate design of thickness 40mm~60mm, 20~30 parts that are once loaded may be implemented, it is contemplated that
The convenience that part is loaded on device, according to leaf spring be loaded position size (40mm × 30mm × 2.5mm) the three of device
A cope plate designs several slots, leaf spring part is directly plugged in the slot of device, after residual stress is eliminated, from device
It is unloaded in slot and takes leaf spring part, improve the convenience of leaf spring part handling.
2) in view of the resistance of deformation of leaf spring part material and part itself is larger (about 1 ton), which is taken
Spiro connection structure, part auxiliary is using welding after the completion of being spirally connected, to achieve the purpose that dual guarantee design strength of the present invention.
3) consider the maximum compressibility 50mm of leaf spring itself, two locating piece height of the two sides of the present invention for the leaf spring that is loaded
Size presses 60mm (leaf spring height dimension 110mm), for limiting leaf spring decrement, guarantees leaf spring compression control in flexible deformation model
Within enclosing, so that it is guaranteed that not being plastically deformed after leaf spring compression.
4) several leaf springs are loaded and are fixed in the present invention, the process die of cover thickness 3mm above leaf spring, in technique mould
The weight (weight is greater than 1 ton) that constant weight is put on plate, after keeping 36H, lays down the weight and process die on leaf spring, from this
It is unloaded in the slot of invention and takes leaf spring, achieve the purpose that eliminate leaf spring residual stress.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
