In the case of up to 7%-8%, it still can restore its original shape.Its corrosion resistance is medical stainless better than best at present
Steel, therefore the application demand of all kinds of engineerings and medicine can be met, it is a kind of very outstanding functional material.
In electronics and mechanical industry application field, nickel-titanium alloy material is often as the structure that can bear aximal deformation value deformation
Part is used, and is the indispensable auxiliary products of many novel light-weight designs.In recent years, made using shape-memory material
Case for the mechanics component of electronic product is more and more, and market prospects are open.In the practical application as mechanics component, nickel
To product, finally workable life cycle has extremely significantly for fatigue life performance of the titanium alloy member in design use scope
It influences, once failure fracture occurs, product can at once be lost using function.And in practical application in industry, special-shaped Nitinol
Material is also very important one of application, and how reasonably to test the fatigue life of special-shaped Nitinol silk material is one important
Subject under discussion.The silk material that conventional overarm method of testing (our company patent CN105388076A) is more suitable for circular cross-section uses, and for different
Shape Nitinol silk material, such as flat filament, polygon silk, band wait for, and the method for test of hanging oneself from a beam has many limitations, while survey of hanging oneself from a beam
Examination method cost is higher, and testing efficiency is low, cannot meet the quick test request of mass.
Utility model content
The utility model lies in that overcome above-mentioned deficiency, it is relatively low to provide a kind of cost, efficient, can meet mass and quickly survey
Try the fatigue life test equipment of desired Nitinol product.
What the purpose of this utility model was realized in：
A kind of fatigue life test equipment of Nitinol product, it include two parallel arrangement the linear guides, two
It is equipped with fixed cross beam between the front end of the linear guide, is additionally provided with movable beam in two the linear guides, before movable beam
End is driven by cylinder, to be slid back and forth along the linear guide, is respectively and fixedly provided at the top of the fixed cross beam and movable beam
Multiple fixtures are clamped in product to be tested between fixed cross beam and movable beam by fixture, and movable beam is front and back
Product to be measured is strutted or compressed in motion process, the start-stop position of movable beam movement is limited by proximal end limiter and distal end
Device controls, and the cylinder, proximal end limiter, distal end limiter are connected with the control system in switch board, work as movable beam
When being moved to the defined position of proximal end limiter, distal end limiter, control system controls cylinder counter motion, removable to realize
The reciprocating motion of crossbeam is moved, counter is provided on rear side of the movable beam, counter is for before recording movable beam
The number moved afterwards, and counter is connected with switch board, the movement time for the simultaneous display movable beam on switch board
Number, until test product is broken.
The fatigue life test equipment of the utility model Nitinol product has the following advantages：
The cost of the fatigue life test equipment of this Nitinol product is relatively low, and testing efficiency is high, can meet mass
The demand quickly tested, and special-shaped Nitinol product is tested, including square, triangle, the NiTis such as ellipse
Alloy wire can more simulate the fatigue life test during straight reciprocating motion.
