DEVICE FOR TESTING GLASS PACKAGING

摘要

The apparatus is intended for testing of compressive strength fatigue in glass packaging. It is used to provide test conditions as close as possible to reality, and provide a variable pressure force that leads to increased reliability of the test results. The apparatus consists of a frame (11) and set of guides (26), on which is mounted an operating mechanism (14) attached to a load apparatus; a load cell (3); a dynamometer (8); and an adjustable fixable plate (9). A passive adjustable plate (12) is attached to frame (11). The loading apparatus is fabricated in the shape of an eccentric mechanism consisting of a shaft (18) connected to the operating mechanism, with an eccentric sleeve (19) mounted on the shaft of said operating mechanism; a second eccentric bushing (21) is mounted on this shaft, with a pressed-on sliding bearing (22) resting on load cell (3), which consists of several replaceable rubber sections. Multiple glass packages under test are placed in a row between the active (9) and passive (12) plates.<IMAGE>
