Description
Technical field
The utility model relates to a kind of tooling device, particularly relates to a kind of tooling device being applied to mechanical test.
Background technology
The tooling device for carrying out three point bending test of existing Metal Material Fatigue testing machine, comprises flexual center, props up roller and bearing down; As shown in Figure 1, upper flexual center is a force roller, under prop up roller and comprise two supporting rollers, sample to be tested is the strip that cross section is rectangle, sample two to be tested is supported in down on two supporting rollers of a roller, apply pressure downwards by the force roller of upper flexual center, thus the bending test completing sample measures the mechanical property of metal material.But traditional three point bending test frock does not have the function of test sample point of application shift value, test Fracture of Metal Material toughness J therefore cannot be met
iCneeds.
Utility model content
Technical problem to be solved in the utility model is the tooling device that will provide a kind of more optimal three point bending test, make sample to be tested accurately can obtain the shift value of the point of application while doing three point bending test, thus can Simultaneously test Fracture of Metal Material toughness J
iC.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of three point bending test tooling device, comprise flexual center, prop up roller and bearing down, lower described roller is two supporting rollers being supported in sample two ends to be tested; Described upper flexual center and the side of described sample contacts are circular arc cylinder, and the two ends of described circular arc cylinder are provided with upper blocking seat holder; Described three point bending test tooling device also comprises:
One upper blocking seat, described upper blocking seat is removably fixedly connected with described upper blocking seat holder, the lower surface of described upper blocking seat be provided with the arm cutting edge of extending of coupling COD crackle rule on to be installed the edge of a knife;
Deck once, described lower deck is arranged at the side of sample, mate setting up and down with described upper blocking seat, described lower deck supports and is arranged on two described supporting rollers, and be installed under the upper surface of described lower deck is provided with the arm cutting edge of extending of coupling COD crackle rule the edge of a knife; Be installed on described the edge of a knife and under the edge of a knife coupling that is installed arrange, can upper flexual center is downward in determination test shift value after Matching installation COD crackle rule between described upper and lower clothing swaging clamp mouth.
The two ends of the described circular arc cylinder of flexual center respectively can be provided with a upper blocking seat holder on described.
Described lower deck is the strip that cross section is square.
Three point bending test tooling device of the present utility model improves upper flexual center structure in former three-point bending frock, is provided with a pair upper and lower deck for fixation of C OD crackle rule extensometer dexterously simultaneously.First upper blocking seat is connected with the upper flexual center partial fixing of redesign during test, lower deck level together with sample is held on down on a roller, two arms of extending that COD crackle is advised vertically are fixed on, two of lower deck are installed (as shown in Figure 5) in the edge of a knife, after on-test, loads, upper blocking seat displacement along with upper pressing down of flexual center, lower deck is then supported in down on a roller geo-stationary, on, between lower deck two edges of a knife, the change of relative distance is the point of application shift value of sample, accurately acquisition can be measured by COD crackle rule, therefore the utility model tooling device is utilized can to realize the function of test sample point of application displacement.Thus can by calculating the fracture toughness J of Simultaneously test sample
iC, realize the object of the J integration determination test of metal material.So greatly save manpower and materials, as long as by a set of three-point bending frock, just a series of comprehensive bending property value can be obtained by single test, both saved experimentation cost and test period, and also agreed with the industrial development theory of energy-saving and emission-reduction.
Three point bending test tooling device structure of the present utility model is ingenious and reliable, easy for installation, wherein why upper blocking seat adopts dismountable structure to be also the ingenious part of the utility model tooling device, because sample to be tested along with test sample different size its highly have different difference, but the spacing of the edge of a knife that is installed up and down of the arm cutting edge installation of extending of coupling COD crackle rule must mate the installation adapting to COD crackle rule, so be installed up and down, the spacing dimension of the edge of a knife should be fixing, demountable structure is adopted to solve this problem just between the upper blocking seat of the utility model upper blocking seat and upper flexual center, by the upper blocking seat changing different size thickness both can ensure the sample of different size load onto rear upper blocking seat on to be installed the spacing being installed under the edge of a knife and lower deck and keeping fixing between the edge of a knife coupling COD crackle rule and install.
