Current can/end growth/buckle tester use inside the dome area of the can for location of the can during test, therefore cans with different height have the same vertical position during the test and do not depend from height of the can. Using flanged long bushing for locating the can with different height and holding expandable plug and distribution parts for air pressure permitted reduce outside dimensions of the tester and reduce weight. Use the position of the testing can on top of expandable rubber bushing by inside the dome area of the can, permitted using almost the same volume of the growth/buckle air for any can, therefore reduce dispersion of measurement values. Area for growth/buckle tests is sealed by expandable rubber bushing with the special internal shape and durometer, which has ability to sealed by inflation any diameter of the testing can and holding growth/buckle pressure during the test. The body of sectional clamps made as I-beam with placing turning cams inside sectional clamps and top holding plates on top of body reduce size and increase rigidity of the tester. Turning pins connect inside turning cams and top holding plates. This connection permit the wall of testing can control rotation both parts. Sectional clamps with turning cams and middle central part hold the testing can in vertical and horizontal positions permitted create uniform holding and clamping force during the tests. Turning cams with rubber plates and middle rubber plate installed on the middle of the sectional clamps permit contact the testing can around and relieve thin-walled can partially from inflation pressure of expandable rubber bushing. Angle of rotation turning cams depend and control by outside diameter of testing can. Extension springs control initial opening position of turning cams. Using Belleville spring and sectional clamps with top holding plates with chamfers for holding testing cans any diameter and height during the test, created stable vertical position of the testing can during growth/buckle tests. Cuts around Bellville spring make path for delivering testing air pressure for the growth/buckle tests. Edges of top holding plates hold testing can around the outside area of the testing can by their chamfers and create necessary space around the stand for growth/buckle tests. sectional clamps pressure hold the can against of the top holding plates and work at the same direction as Belleville spring making fixed vertical position of the testing can that increase tolerance of the tests. Pressure for inflation is coming directly to expandable rubber bushing, movement sectional clamps and growth/buckle tests deliver from the same manifold.
Placement of the testing can on top of Belleville spring and air pressure push the testing can to the same direction as Belleville spring allow make growth/buckle tests for testing cans with any height, does not have any additional replaceable parts, units (such as cylinders) and holding parts for holding testing cans during testing different diameters and height of testing cans as current designs do
Combination of mechanical properties of rubber, variation of thickness of the internal wall of the rubber bushing and the durometer of rubber allow create chamber between expandable rubber bushing and testing can for any diameters of the cans, which hold testing pressure.
The chamber with almost the same volume created by this unique design for any testing can, method of placing of testing can, needless air accumulators for quickly compensation differences of volume of the air for different size of cans, reducing time of the test and reducing dispersion of measurement values, as current designs do, make tests more accurate.
Each holding clamps include three separate parts:
The angle of rotation of sectional turning cams control by contacting the testing can.
