Abstract
A Vickers micro-hardness test sample preparation device consists of a bracket (1), an impact rod (2), a spring (3), an iron block (4) with plasticine and a base (5), wherein the iron block with the plasticine is placed on a work plane at the upper part of the base (5), and a bracket guide pole hole perpendicular to the work plane at the upper part of the base (5) is formed at the upper part of the bracket (1); and the spring (3) is sleeved at the upper part of the impact rod (2), and the impact rod (2) and the bracket guide pole hole are in sliding fit. The uneven side of a sample is placed on the plasticine, and arranged on the working face of the base right below the impact rod together with the iron block, and the impact rod is depressed to enable the plasticine and the sample to be in close combination, so that the uneven side of the sample is smooth for hardness test, polishing two sides of the sample to be smooth and flat is not required, the work efficiency is improved, and abrasive paper is saved simultaneously; the plasticine is reusable and has lower cost; and the Vickers micro-hardness test sample preparation device has the advantages of simple structure, reliability in operation and convenience in use.
Description
Technical field
The utility model relates to a kind of micro-vickers hardness test sample preparation device, belongs to the material test equipment technical field.
Background technology
Hardness is one of important performance indexes of weighing in metal material, is the overall target of mechanical properties such as elastic properties of materials, plasticity, intensity and toughness, and it is meant the ability of material opposing elastic deformation, plastic yield or destruction.Facts have proved between hardness of metal materials value and intensity level and other mechanical property certain relation is arranged, can estimate other mechanical property of material according to hardness.
Hardness comprises Bu Shi, Rockwell, Vickers hardness etc., can convert according to Bu Shi, Rockwell, the Vickers hardness number table of comparisons.Because the test force rate of Vickers is more; Measurement range is more extensive; Can measure used almost whole metal materials in the present industry; (3000 Vickers units) all can measure from very soft material (several Vickers unit) to very hard material, therefore in real work, need often carry out Vickers hardness test.
And hardness test is had relatively high expectations to specimen surface flatness and smooth finish, promptly requires the specimen surface smooth planar, non-scale and external dirt; Especially the grease that do not have therefore need polish to sample, and metal is harder; If the sample two sides is all made smooth bright and clean; Not only time and effort consuming can not draw experimental result timely, and hardness test only needs make an experiment to one side and get final product most of the time.If the specimen surface that can adopt a kind of method will need not carry out hardness test flattens whole fast and does not influence test findings or influence smaller; The one side that only needs to make an experiment polishes smooth smooth; This also can practice thrift sand paper simultaneously with very big increasing work efficiency, and reduces cost.
Summary of the invention
The purpose of the utility model is, discloses a kind of micro-vickers hardness test sample preparation device, can improve the work efficiency of hardness test effectively.
The utility model solves the technical scheme that its technical matters adopted: said device is made up of the iron block 4 and the base 5 of support 1, impact rod 2, spring 3, band plasticine.Support, base are processed by cast iron, and the iron block of band plasticine is placed on the working face on base 5 tops, and the support guide pillar hole vertical with base 5 top working faces arranged at support 1 top, and bracket base has four bearings, guarantees that it is steady; Spring 3 is sleeved on and impacts excellent 2 tops, and impacting between rod 2 and the upper bracket guide pillar hole is sliding fit, can in support guide pillar hole, move up and down behind the elastic force that overcome spring 3.After pressing excellent impact specimen of impact and plasticine 4, because spring action can make it set back; It is smooth only to need one side with sample polish smooth, and then sample is not placed on the plasticine on the plane, places on the base top working face that impacts under the rod with iron block; Press and impact rod, plasticine and sample are not combined closely on the plane, the plane is not smooth to make sample; Can carry out hardness test, thereby improve work efficiency effectively, also practice thrift sand paper simultaneously; And plasticine is reusable, has reduced cost.
The beneficial effect of the utility model is: during the sample preparation of micro-vickers hardness test sample; The one side that only need will make an experiment polishes smooth smooth, re-uses the sample preparation of the utility model device, can carry out hardness test; Improved work efficiency effectively; Simultaneously also practiced thrift sand paper, and plasticine is reusable, has reduced cost.On the other hand, the utility model is simple in structure, and it is easy and durable to select materials, and reliability is also very high.

Picture in picture number expression: the 1st, support; The 2nd, impact rod; The 3rd, spring; The 4th, the iron block mounting table of sample and band plasticine; The 5th, base.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is elaborated.
As shown in Figure 1, be the structural representation of present embodiment.Device is made up of the iron block 4 and the bracket base 5 of support 1, impact rod 2, spring 3, band plasticine.Support 1 and bracket base 5 are processed by cast iron, and the iron block of band plasticine is placed on the working face on base 5 tops, and four bearings are arranged at bracket base 5 bottoms, keep it steady; Spring 3 is sleeved on and impacts excellent 2 tops, and impacting between rod 2 and the upper bracket guide pillar hole is sliding fit, can in support guide pillar hole, move up and down behind the elastic force that overcome spring 3.Press and impact rod 2, overcome the elastic force impact specimen and plasticine of spring 3 after, owing to spring action can make it set back.During use, it is smooth only to need one side with sample polish smooth, and then that sample is uneven one side is placed on the plasticine; On the base top working face under iron block places the impact rod, press and impact rod, plasticine and sample are not combined closely on the plane; Even the sample out-of-flatness also can be carried out hardness test, thereby has improved work efficiency effectively; Simultaneously also practiced thrift sand paper, and plasticine is reusable, has reduced cost.
Shown in Figure 2 is hardness sample enlarged diagram.Similar microhardness hardness test sample all can adopt the method to carry out sample preparation, and is convenient and swift.
Claims (1)
1. a micro-vickers hardness test sample preparation device is characterized in that said device is by support (1), the iron block (4) that impacts rod (2), spring (3), band plasticine and base (5) formation; The iron block of band plasticine is placed on the working face on base (5) top, and support (1) top has and the vertical support guide pillar hole of working face, base (5) top; Spring (3) is sleeved on and impacts rod (2) top, impacts between rod (2) and the upper bracket guide pillar hole for being slidingly matched.
