Utilize the utility model discloses an anchor clamps are used in test of coating bonding strength at system appearance in -process, can keep the centering degree between sample and the tensile stick well to the even bonding between sample and the tensile stick be can promote, thereby the accuracy and the validity of final test result are guaranteed.
Description
Technical field
The utility model relates to a kind of anchoring strength of coating fixture for testing.
Background technology
Prepare various functional coatings in metal surface by hot-spraying technique, can effectively promote goldBelong to the various performances of matrix. Bond strength between coating and matrix is that can coating play a roleA key index.
Fig. 1 shows a kind of anchoring strength of coating test block, surface spraying is had to the examination of coating 5The upper and lower surface of sample 4 is fixed with up-down stretch rod 1 by powerful viscose glue 6 respectively. Logical againCross the pin-and-hole 3 arranging on the end 2 of up-down stretch rod 1 and be fixed with mechanical test machine, logicalOverstretching is peeled away coating 5 and sample 4, utilizes maximum fracture tensile force to weigh coating 5Bond strength with sample 4.
In the test block shown in Fig. 1, sample 4 is all cylindrical with up-down stretch rod 1 conventionally,And diameter is identical. In gluing sample making course, sample 4 often can be sent out with up-down stretch rod 1Raw skew, can not keep good alignment degree, thereby affects the accurate of final bond strength testProperty.
Utility model content
The purpose of this utility model is to provide a kind of anchoring strength of coating fixture for testing, its energyEnough improve the accuracy of final testing result.
According to anchoring strength of coating fixture for testing of the present utility model, comprise upper die and lower die,Upper die and lower die are respectively arranged with the circular groove to joining, and between upper die and lower die, are also provided withFastening structure.
Under preferable case, on upper die and lower die, the number of circular groove is 5.
Under preferable case, the radius of circular groove is 25mm.
Under preferable case, the radian of circular groove is 1/3-1/2 arc length.
Under preferable case, fastening structure is the bolt hole being arranged on upper die and lower die side, logicalCrossing bolt is fastenedly connected.
Under preferable case, upper die and lower die are made up of stainless steel material.
Utilize anchoring strength of coating fixture for testing of the present utility model, in sample making course,The alignment degree between sample and stretching rod can be kept well, and sample and stretching rod can be promotedBetween even bonding, thereby ensure accuracy and the validity of final testing result.
Brief description of the drawings
Fig. 1 is a kind of anchoring strength of coating test block schematic diagram.
Fig. 2 is the end face signal according to anchoring strength of coating fixture for testing of the present utility modelFigure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described. Those skilled in the art shouldUnderstand, below describe only for explaining the utility model but not for it being made to any restriction.
Referring to Fig. 2, according to anchoring strength of coating fixture for testing of the present utility model, compriseMould 10 and counterdie 20. On patrix 10, be provided with circular groove 11, on counterdie 20, be provided withTo the circular groove 21 of joining. Between patrix 10 and counterdie 20, be also provided with fastening structure 12With 22. Under preferable case, patrix 10 and counterdie 20 adopt identical structure, therebyConvenient manufacture.
Referring to Fig. 1, when the sample 4 that is coated with coating 5 is by viscose glue 6 and up-down stretch rod 1After preliminary fixing, by first test block horizontal positioned in the circular groove 21 of counterdie 20, thenCover patrix 10, make the circular groove 11 of patrix 10 and the circular groove 21 of counterdie 20To joining, block test block. Pass through again fastening structure 12 and 22 by patrix 10 and counterdie 20Be fastened to together, clamp test block. Then integral clamp is erect and is placed into 60-200 DEG CIn drying box, make viscose glue heat preservation solidification.
In order to make test result more accurate, conventionally adopt multiple parallel samples 4 to carry out parallel surveyExamination, therefore in anchoring strength of coating fixture for testing of the present utility model, patrix 10 and underOn mould 20, the number of circular groove is preferably 5. By trying with 5 tests of a collection of preparationSample, ensures sample preparation uniformity.
Patrix 10 and counterdie 20 circular grooves 11 and 21 are for roughly semicircle, its radius withThe main diameter of up-down stretch rod 1 is identical, is preferably 25mm. In order to make the fixture can be effectiveClamp up-down stretch rod 1, the radian of circular groove 11 and 21 will be slightly less than 1/2 arc conventionallyLong, be preferably 1/3-1/2 arc length.
Fastening structure 12 and 22 can be for being arranged on the bolt on patrix 10 and counterdie 20 sidesHole, is fastenedly connected by bolt; Also can adopt screwed hole, be undertaken fastening by screwConnect.
Because fixture is fixing after up-down stretch rod 1 and sample 4, be placed in drying boxBe incubated, and fixture is wanted long-time Reusability. In order to prevent fixture oxidation and rusting and changeShape, patrix 10 and counterdie 20 preferably adopt stainless steel material to make.
Prepare anchoring strength of coating test sample by fixture of the present utility model, can be effectivePrevent the slippage in bonding process of stretching rod and sample, keep good alignment degree. And energyEnough make sample and stretching rod in viscose glue solidification process, keep erectting and place, can effectively prevent from gluingGlue trickles in heat preservation solidification process, makes test block bonding evenly. Thereby, effectively ensureAccuracy and the validity of anchoring strength of coating test result.
