Horizontal impact testing machine and testing method for impact resistance of glass

Abstract

The invention discloses a horizontal impact testing machine for impact resistance of glass and a testing method, and belongs to the field of glass detection. The horizontal impact testing machine comprises a control box, an air compressor, an air storage tank, a steel ball bin, a guide sliding cylinder and a glass sample supporting frame; wherein the air compressor is communicated with the air storage tank, an air outlet of the air storage tank is communicated with the steel ball bin, a pressure release switch is arranged at the air outlet of the air storage tank, and steel balls of different specifications can be arranged in the steel ball bin; the air compressor and the pressure release switch are electrically connected with the control box; the guide sliding barrel is horizontally arranged, an inlet of the guide sliding barrel is communicated with the steel ball bin, a glass sample supporting frame is arranged at an outlet of the guide sliding barrel, a glass sample is vertically fixed by the glass sample supporting frame, and the glass sample supporting frame can move up and down. The steel balls with different sizes and weights and different impact speeds and kinetic energy are provided for glass samples with different specifications, the restriction of the height space of a test room is solved, the detection efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to the field of glass detection, in particular to a glass impact resistance level impact testing machine and a testing method. Background technique [0002] At present, the impact resistance test of glass generally adopts the falling ball impact method. The falling ball impact method is to drop steel balls of specified mass from different heights to measure the impact resistance of glass. However, the falling ball impact method has the following deficiencies in actual use: [0003] 1. The impact height of the falling ball specified in some standards is relatively high. For example, the impact height of the falling ball of the safety glass of the car will reach 12 meters. The high impact height will not only make the test equipment too tall and expensive, but also occupy a large laboratory space. To meet the high requirements of test equipment, the laboratory also needs to be specially modified, which virtually increases the cost ...

AI Technical Summary

Problems solved by technology

[0003] 1. The impact height of the falling ball specified in some standards is relatively high. For example, the impact height of the falling ball of the safety glass of the car will reach 12 meters. The high impact height will not only make the test equipment too tall and expensive, but also occupy a large laboratory space. To meet the high requirements of test equipment, the laboratory also needs to be specially modified, which virtually increases the cost of testing

[0004] 2. When the glass sample is replaced or the equipment is in an accident, if the steel ball limit device fails and the steel ball falls, it may cause serious injury to the test personnel

[0005] 3. The steel balls in some test devices can only be used for a single drop ball impact test. The steel balls need to be replaced after one impact. Some tests require 20 times for a single group, and the test efficiency is extremely low
