Description
Technical field
The present invention relates to testing equipment field more particularly to Apparatus for Bending at low-temp fields, specifically a kind of to be used for electric power
Industry tubulose charges the Apparatus for Bending at low-temp of managing security tools and instruments and tubular composite material.
Background technique
The bending property of power industry tubulose electrification managing security tools and instruments and tubular composite material is to examine the material and product
The important indicator of performance, existing market there is no standard device to detect it.Commercially available Apparatus for Bending at low-temp or universal testing machine are more
For the segments sample such as steel pipe, reinforcing bar and plastic tube, power industry tubulose electrification managing security tools and instruments is unable to satisfy from carrying jig
And the test of tubular composite material needs.Since the Work tool shape of power industry is special, and length dimension is larger, conventional examination
Proved recipe method is then to pass through weights to examination in the central position of sample by the both ends of simple beam mechanism supports sample
Sample applies pressure.Although this method is simple, in addition for a certain type it is also very practical, however its defect is also obvious
's.Specifically, existing electric power instrument includes the multiple types such as insulating ladder, insulating bar, insulating bar, bottle-holding rack, and
Its length of each type of sample and shape are all different, and this simple bracket institution applicability is poor, are unable to satisfy all kinds of
The positioning requirements of kind of sample, reliability and stability it is difficult to ensure that；Due to being loaded by weights, loading speed often reaches
Less than test requirements document, lead to the poor repeatability of test, test result inaccuracy；Since the position adjustment and load of sample all need people
Work is completed, thus labor intensity is high, and efficiency is very low.
Summary of the invention
The present invention is to solve the above problem of the existing technology, it is desirable to provide a kind of versatility is good, test is accurate
The Work tool Apparatus for Bending at low-temp that degree is high, labor intensity is low and high-efficient.
To solve the above problems, the invention adopts the following technical scheme: Work tool Apparatus for Bending at low-temp, including it is guide rail, omnipotent
