Description
Technical field
The utility model relates to a kind of centralising device that is suitable for plate forming testing machine and carries out conical cup test, belongs to plate stamping former technical field.
Background technology
Sheet material forming testing machine is the testing machine that one is exclusively used in qualification and discriminating Sheet metal forming (punching press) performance, is the useful tool of controlling plate rolling quality, reasonable selection punching press plate.Germany Erichsen plate forming testing machine is mainly used in the research of Automobile Plate impact briquetting test, possesses the protruding test of cup, lug test, hole expansion test, FLC, the test capability of the aspects such as hydraulic forming, conical cup test.Wherein in the time doing conical cup test, between the project organization feature of testing machine own, in the time of each conical cup test, while placement due to sample, there is no special sample centering tooling, sensation is placed sample completely artificially, and while causing sample placement, position there will be and departs from.The position that simultaneously different testing crews is placed also may be different, causes conical cup test drift in punching course, easily to make sample skew, causes conical cup test failure.Due to each sample placement location difference, make test figure homogeneity poor, test parameters deviation is large, affects test effect, has also reduced test efficiency simultaneously.Be more than the ubiquitous problem of conical cup test in plate forming, not yet effectively solved so far, be therefore necessary the centering of conical cup test to carry out Improvement and perfection.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of centralising device for plate forming testing machine conical cup test, this centralising device can accurately be located cone cup sample, ensure that each sample placement location fixes, thereby improve the Stability and veracity of conical cup test, ensure conical cup test success ratio on plate forming testing machine.
The technical scheme solving the problems of the technologies described above is:
A kind of centralising device for plate forming testing machine conical cup test, it is a rectangular fixture block, one side of fixture block has snap ring and inner sleeve, snap ring is in the bottom of fixture block, snap ring is fan-shaped breach, the excircle of the drift base module that the radian of snap ring sector notch and plate forming testing machine instrument itself carry matches, it above snap ring, is inner sleeve, inner sleeve is similarly sector notch, the center of circle of inner sleeve sector notch overlaps with the center of circle of snap ring sector notch, the sector notch radian of inner sleeve with matched by test agent excircle.
The above-mentioned centralising device for plate forming testing machine conical cup test, fluted on the bottom surface of described snap ring, groove is along the fan-shaped marginal distribution of snap ring.
The above-mentioned centralising device for plate forming testing machine conical cup test, described centralising device is made up of multiple fixture blocks, and the snap ring of multiple fixture blocks is identical, and the radian of the sector notch of their inner sleeve is the sample of corresponding different-diameter respectively.
The beneficial effects of the utility model are:
(1) the utility model can accurately be located conical cup test sample position, to realize the strict centering of sample and drift movement locus, has avoided sample skew, has improved test accuracy.
(2) before this centralising device assembling application, testing machine cone cup experiment related die need be installed, comprise drift base module, sample drift etc., and the use of this centralising device completely can cone of influence cup the installation of experiment self mould, and can not have any impact to the precision of cone cup experiment mould.
(3) it is accurate that the utility model makes the each placement positioning of sample, drift is in the process of impacting, success of the test rate reaches 100%, and sum up 10 groups of samples (Automobile Plate DC03 is as a comparison sample, and thickness is 0.15mm, sample diameter be-) by contrast, after comparative analysis test cone cup value finds that this centralising device comes into operation, not only make success of the test rate reach 100%, improved test efficiency simultaneously, can complete 30 tests by 20 original tests/hour mention are per hour.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the side view of Fig. 2.
In figure, mark is as follows: fixture block 1, snap ring 2, inner sleeve 3, groove 4.
Embodiment
The utility model is a rectangular fixture block 1, and a side of fixture block 1 has snap ring 2 and inner sleeve 3.
In figure, show, snap ring 2 is in the bottom of fixture block 1, and snap ring 2 is fan-shaped breach, and the radian of snap ring 2 sector notch matches with the excircle that cone cup is tested required drift base module.Conical cup test drift base module external diameter size, is fixed measure, determines reference point for centralising device, reaches centering effect accurately.
In figure, show, be inner sleeve 3 above snap ring 2, and inner sleeve 3 is similarly sector notch, and the center of circle of the sector notch of inner sleeve 3 overlaps with the center of circle of the sector notch of snap ring 2, and the radian of the sector notch of inner sleeve 3 and different-diameter excircle match.Inner sleeve 3 internal diameters are identical with the external diameter of sample, are used for fixing sample position, ensure centering.Before experiment, first this fixture block 1 device is placed on base, snap ring 2 is mated with the circumference on base, sample is installed afterwards, how much centers of circle that make sample in same position, ensure the centering of sample with inner sleeve 3 centers of circle, remove afterwards this centralising device, start to test.
Centralising device is made up of multiple fixture blocks 1, and the snap ring 2 of multiple fixture blocks 1 is identical, and the radian of the sector notch of their inner sleeve 3 is the sample of corresponding different-diameter respectively.Be all available uses of sample of 36mm, 50mm, 60mm, 78mm to the diameter of standard-required, the inner sleeve 3 that adapted is different.
In figure, show, fluted 4 on the bottom surface of snap ring 2, groove 4 is uniform along the fan-shaped edge of snap ring 2.Groove 4 is for making this centralising device contact more closely and design with drift base module, for eliminating the gap of centralising device and drift base module, ensured that the two can close contact, reaches the required centering effect of test.
The utility model course of work is as follows:
When use, first plate forming testing machine protective cover is opened, changed the required various parts of conical cup test, the luggage of going forward side by side is joined.Conical cup test drift position is dropped to minimum by controlling hydraulic oil pump afterwards, whether the position of observing drift is axially vertical, then drift base module located.Now the forming tester conical cup test centralising device of exploitation is placed on drift base module, in conjunction with different sample sizes, change the inner sleeve 3 of different-diameter, sample is placed in centering module, when placement, sample outward flange is adjacent to centralising device inner sleeve gently, ensure centering position, take away gently afterwards conical cup test centralising device, open hydraulic pressure and build protective cover, combined standard sets impact velocity, pressure-pad-force, the parameters such as the stroke limit, can test, ensure the strict centering of specimen width and thickness direction, stop the relative displacement of sample and drift.
