Abstract
The utility model relates to an auxiliary facility for detection of metal material elongation, in particular to an auxiliary support for elongation measurement. The auxiliary support is characterized in that a V-shaped support groove is formed by a steel plate; the pointed-end bottom of the V-shaped support groove is fixedly connected to a center line of a strip-shaped flat plate in the length direction; and the length of the V-shaped support groove is equal to that of the strip-shaped flat plate. The auxiliary support for elongation measurement is simple in structure and convenient to operate, can improve measurement accuracy and working efficiency for measurement, and can reduce labor intensity of measuring personnel.
Description
Technical field
The utility model detects the auxiliary equipment, particularly a kind of elongation measurement auxiliary stand of metal material length growth rate.
Background technology
The metal material length growth rate is the important mechanical property project that detects metal material plasticity quality, its performance represents the plastic yield of material metal material production and non-destructive ability, and the measurement of length growth rate is exactly the gauge length increment of sample under certain stress and the ratio of original gauge length.In order accurately to measure elongation after fracture, before stretching, delineate continuous gauge length at sample, after waiting to draw high off-test, the part of sample fracture carefully connected its axis is on the same straight line, and take special measure to guarantee that the sample fracture part suitably measures the sample gauge length of having no progeny in the contact back.We contact and pin with hand two parts sample that will rupture in the field practice of " taking special measure to guarantee the suitably contact of sample fracture part ", use vernier caliper to measure operation on the other hand in addition, for sheet coupon, this measuring method is fine, because sheet coupon adopts the standard reduced sectien specimen, during butt joint fracture contact sample because sample is the plate face is positioned on the testing stand and can produce movement: and for the pole sample, screw thread pole sample, operation is very inconvenient like this, pole or screw thread pole sample are when the splicing fracture surface of sample, because fracture face is irregular, pole can produce rolling during sample itself, therefore when having no progeny elongation, measurement often fails, need check fracture again during measurement, with pressing splicing fracture two ends on the other hand, one hand is measured operation, make troubles for laboratory technician's measurement operation and efficient very low, the risk that also can cause accuracy of measurement to reduce.
Summary of the invention
The purpose of this utility model is to provide a kind of elongation measurement auxiliary stand, and it is simple in structure, and is easy to operate, not only can improve accuracy of measurement, and can reduce the labour intensity of survey crew, improves surveying work efficient.
The purpose of this utility model is achieved in that a kind of elongation measurement auxiliary stand, constitute the V-arrangement support slot by steel plate, the most advanced and sophisticated bottom of V-arrangement support slot is fixed on the center line of bar-shaped plate length direction the length of V-arrangement support slot and the equal in length of bar-shaped plate.
The utility model is affixed the V-arrangement support slot that is made of steel plate on bar-shaped plate.After tension test finishes, with the sample butt joint of breaking, and will delineate a little towards on be placed on the V-arrangement support slot, carry out the mensuration of elongation after fracture then after to zero point with vernier caliper.The utility model can make the operator break the experiment work that the sample elongation after fracture is measured need not hand steeredly pressing easily to finish under the situation that fracture connects, both easy and simple to handle, reduce personnel labor intensity, increase work efficiency, also accuracy of measurement can be promoted greatly, this elongation measurement auxiliary stand is good, easy and simple to handle through the on-the-spot verification the verifying results that uses.
The utility model is simple in structure, and is easy to operate, not only improved the accuracy of measuring, and reduced the labour intensity of survey crew, improved surveying work efficient.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.Fig. 1 is perspective view of the present utility model.
Embodiment
A kind of elongation measurement auxiliary stand as shown in Figure 1, constitutes V-arrangement support slot 1 by steel plate, and the most advanced and sophisticated bottom of V-arrangement support slot 1 is fixed on the center line of bar-shaped plate 2 length directions the equal in length of the length of V-arrangement support slot 1 and bar-shaped plate 2.V-arrangement support slot 1 is made of the angle steel of 20mm * 20mm, and the length of V-arrangement support slot 1 is 200-250mm.Bar-shaped plate 2 is made of band steel, and the width of band steel is 30mm.The angle of the groove face of V-arrangement support slot 1 and bar-shaped plate 2 is 45 °.
