Chromium alloy glass testing machine with hydraulic platen, fragment collector and circular-track pressing plate

Abstract

The invention relates to a tempered glass testing inspection machine. A chromium alloy glass testing machine with a hydraulic platen, a fragment collector and a circular-track pressing plate is characterized in that a supporting base plate is fixed to the lower end of a broken gap formed in a rear plate upper plane, a T-shaped guide rail is arranged at the center of the lower plane of the rear end of a testing platen, and a hydraulic lifting mechanism is arranged between the T-shaped guide rail and the supporting base plate. A machine frame front middle pull rod, a machine frame front upper pull rod and a machine frame rear upper pull rod jointly fix the fragment collector. A circular-track pressing plate assembly is fixed to the upper plane of the testing platen. The stepped lower surface of a sliding plate part is a sliding plate lower plane, a round groove is formed in the sliding plate lower plane, and a centrally symmetric transitional groove is formed between the round groove and the sliding plate lower plane. The upper surface of a pressing plate part is a pressing plate upper plane, a circular convex track is arranged on the pressing plate upper plane, and a centrally symmetric transitional convex strip is arranged between the circular convex track and the pressing plate upper plane. The sliding plate lower plane and the pressing plate upper plane are located on the same height. Bursting caused by non-uniform local stress of tempered glass plates is avoided.

Description

technical field [0001] The invention relates to a test and inspection machine for tempered glass, in particular to a chromium alloy glass testing machine with a hydraulic platform debris collector, a circular rail press plate, which can be enlarged or reduced around the press plate and uses a reversible workbench to test glass performance indicators . Background technique [0002] Fragmentation test is a main way to detect the quality of tempered glass. According to the requirements of national standards, after the 3mm thick tempered glass is broken, the fragments in any 50*50mm should be more than 30 pieces, and the 4mm~12mm thick tempered glass is broken. Fragments within any 50*50mm should be larger than 40 pieces, and a small amount of long fragments are allowed, the length of which should not exceed 75mm. The direction of the strip-shaped fragments should be roughly parallel to the edge of the glass. If they are not parallel, the included angle should not exceed 45 d...

Problems solved by technology

This method is not only inconvenient to operate, it takes a long time, and the tape is a disposable product, which is easy to cause waste and pollution, and the tape residue on the test bench must be removed after each test to remove the broken glass, otherwise , the remaining glass fragments will affect the next experimental test operation

At the same time, the adhesive tape is also likely to be broken by the force of the tempered glass explosion, causing the operator to be injured. Therefore, it is very necessary to improve the tempered glass fragment test device

[0004] Chinese patent application number: 2009203050079, tempered glass falling ball test bench, in order to solve the problem of glass fragments splashing everywhere when tempered glass is used for experiments, the method of supporting frame box is adopted, although it can effectively remove glass fragments, it is inconvenient to read glass fragments , and the installation efficiency of continuous multi-piece tempered glass is low

[0005] China's other patent application number: 201420595067.X, tempered glass shard state test device, proposed some new methods and measures to deal with the pressure plate of brittle glass, but it is still impossible to adjust the size at will, and it is impossible to make the four sides of the pressure plate all in the same on flat surface

At least one side of the patent must not be in contact with the test bench surface

What is referred to as the suspended retaining wall 5 in the embodiment cannot be in contact with the base 1 simultaneously with other three-sided retaining walls, so the retaining piece 4 has to be used to make up the gap between the suspended retaining wall 5 and the base 1, resulting in four Uneven surrounding force

In addition, the width of the baffle 4 itself is fixed, and only multi-piece splicing can be used, and continuous changes of different widths cannot be achieved.
