Not only detecting the precision height, moreover can be accurately combining the adhesion strength at interface to detect with the basic unit to compound layer, fundamentally have solved prior art and has examined time measuring carrying out the clad steel plate adhesive strength, system appearance difficulty, detects the technological problem of the unable detection of low, the thin specification clad steel plate adhesive strength of accuracy.
Description
Technical field
The utility model relates to a kind of and the matching used clad sheet steel sample of clad sheet steel combination interface bonding strength detection fixture, belongs to clad sheet steel and detects apparatus technical field.
Background technology
Interfacial adhesion strength is the ability characterizing clad sheet steel combination interface anti tear under normal force effect, is an important indicator of evaluating combined steel plate bond strength.The length of clad sheet steel interfacial adhesion strength test samples is the thickness of clad sheet steel, the thickness of current conventional clad sheet steel only has about 10mm, and cladding thickness only only has several millimeters, directly cannot clamp test samples with cupping machine and carry out tension test.The clad sheet steel interfacial adhesion strength detection method that standard GB/T-T6396 recommends is: during sample preparation in the thicker basic unit of clad sheet steel sample, bore by mach mode and beat blind hole, the degree of depth of blind hole need be greater than groundwork thickness but can not be greater than the gross thickness of clad sheet steel; Put in sample blind hole with cylindrical crimp during detection and apply normal pressure until cladding comes off.It can thus be appreciated that existing detection method sample preparation is numerous and diverse, need to bore on sample to beat blind hole, cannot with Linear cut etc. accurately cutting equipment process, machining can only be carried out with lathe.And during machining, shake on the one hand and impact larger, certain impact can be produced to the combination interface of clad sheet steel, thus affect the accuracy of testing result, the ability that the anti-normal direction of clad sheet steel combination interface is torn can not be reflected really, if the basic unit of clad sheet steel and cladding are in conjunction with poor, even in sample making course, just can there is cracking and cause sample preparation failure; The precision of machining is lower on the other hand, and the situation of punching sample or not wearing combination interface, easily appears in the cladding very thin thickness of clad sheet steel in sample making course in addition, thus causes sample preparation failure.Secondly, the method accuracy of detection is low, and when detecting, need pressure head to stretch into sample blind hole applying pressure, make the annular of sample by inspection region uniform stressed, and have certain tapering with the machine-tooled method brill blind via bottom beaten on sample, therefore be difficult to when detecting ensure that the annular of sample is by inspection region uniform stressed, will inevitably concentrate and affect the accuracy of testing result by build-up of pressure.What is more important, is less than the clad sheet steel of 10mm for thickness, its cladding thickness only has about 1mm, cannot realize sample preparation and detection by existing method at all.Therefore, be necessary to be improved prior art.
Summary of the invention
The purpose of this utility model is to provide a kind of and the matching used clad sheet steel sample of clad sheet steel combination interface bonding strength detection fixture, accurately can detect clad sheet steel combination interface bonding strength.
The utility model is completed by following technical proposal: a kind of and matching used clad sheet steel sample of clad sheet steel combination interface bonding strength detection fixture, comprise cladding, basic unit and tack coat, it is characterized in that cladding is set to cuboid, this cuboid is connected with the frustum of basic unit by tack coat, the frustum of basic unit and the cuboid of basic unit are integrated, respectively the cladding of cuboid and the basic unit of cuboid to be placed in the groove of corresponding upper and lower grip shank when detecting.
Described frustum is rectangle frustum, its upper end is little, lower end is large, upper end is connected with cladding cuboid by tack coat, the cuboid of lower end and basic unit is connected as a single entity, thus make the tack coat area at cladding and combination interface place of basic unit minimum, and then can only disconnect from this bonding part when detecting, reach Detection results.
Described clad sheet steel combination interface bonding strength detection fixture, comprise upper and lower two grip shank that upper and lower chuck is matched with cupping machine respectively, one end that wherein upper and lower two grip shank are relative is equipped with groove, the bottom land of groove is provided with opening, this opening is communicated with groove, so that after upper and lower two grip shank connect, sample to be tested is snapped in groove corresponding to upper and lower grip shank, can detect.
The opening of described groove and groove bottom land forms inverted convex shape structure, to facilitate clamping sample.
Cell wall between described groove and bottom land opening is set to circular arc, to increase cell wall intensity, prevents groove to be out of shape in drawing process.
Described grip shank pommel outside surface is provided with anti-skidding male and fomale(M&F), skids when stretching to prevent it.
The utility model has following advantages and effect: adopt such scheme, not only sample sample preparation is simple, direct machine work just can obtain the sample of desired structure, this sample holder is very convenient, directly snap in, in lower groove, not only accuracy of detection is high, and can detect the cohesive strength of cladding and basic unit's combination interface exactly, fundamentally solve prior art when carrying out clad sheet steel bonding strength and detecting, sample preparation difficulty, detection accuracy is low, the technical barrier that Thin Specs clad sheet steel bonding strength cannot detect, be a desirable clad sheet steel combination interface bonding strength detection fixture in fact, and supporting sample with it.
