Description

Technical Field

[0001] This utility model relates to the field of glass production equipment, specifically to a tempered glass strength testing device. Background Technology

[0002] Tempered glass is a type of prestressed glass. Through physical (heating followed by rapid cooling) or chemical (ion exchange) processes, compressive stress is formed on the surface and tensile stress is formed internally, thereby improving its strength and safety. To test the performance of tempered glass, its strength needs to be tested, including impact strength testing, which is used to evaluate the impact resistance of tempered glass. Examples include the falling ball impact tester and the shot bag impact tester. The former tests the glass surface's penetration resistance by having a steel ball fall freely from different heights and impact it; the latter is used to verify the safety strength performance of tempered laminated glass for building applications. Traditional falling ball impact testers have a significant drawback: the steel ball may bounce back after impacting the sample, causing a secondary impact on the sample. This can lead to inaccurate test results, especially under critical conditions, which may directly cause misjudgment. Therefore, it is necessary to design a tempered glass strength testing device that can capture the impacted steel ball and ensure accurate test results. Utility Model Content

[0003] The purpose of this invention is to provide a tempered glass strength testing device that can capture the impacted steel ball, ensuring accurate test results.

[0004] The technical solution adopted is as follows:

[0005] A tempered glass strength testing device includes a frame, a lifting slider, a steel ball delivery device, and a steel ball capture mechanism. A worktable is mounted on the frame.

[0006] The lifting slider is slidably mounted on the frame and located above the worktable.

[0007] The steel ball dispensing device is installed on the lifting slider.

[0008] The steel ball catching mechanism is mounted on the frame and located above the worktable.

[0009] The steel ball catching mechanism includes a conical funnel.

[0010] A baffle is rotatably installed at the lower end of the conical funnel, and a high-speed motor connected to the baffle is installed at the lower end of the conical funnel.

[0011] Preferably, the frame is provided with a lifting frame, and the lifting frame is connected to a protective cover that covers the workbench.

[0012] Preferably, the steel ball dispensing device includes an electromagnet adsorption plate, with steel balls adsorbed at the lower end of the electromagnet adsorption plate.

[0013] Preferably, a guide column is vertically arranged on the frame, the lifting slider is slidably connected to the guide column, and an electric telescopic cylinder is vertically arranged on the frame, the upper end of the electric telescopic cylinder being fixedly connected to the lifting slider.

[0014] Preferably, the lower end of the lifting slider is provided with a downward-facing laser emitter, which is used for positioning the conical funnel.

[0015] Compared to existing technologies, the advantages are:

[0016] In this invention, a steel ball falls from a conical funnel and impacts the tempered glass placed on the worktable. As the steel ball bounces up, it re-enters the conical funnel. A high-speed motor drives a baffle to rotate to the lower end of the conical funnel to block the steel ball and prevent it from impacting the tempered glass a second time, thus ensuring the accuracy of the tempered glass impact test.

[0021] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:

[0022] Example 1: A tempered glass strength testing device includes a frame 1, a lifting slider 2, a steel ball launching device, and a steel ball capturing mechanism. A worktable 3 is provided on the frame 1. The worktable 3 is horizontally positioned and is used to place tempered glass for impact testing. The lifting slider 2 is slidably mounted on the frame 1 and located above the worktable 3. The steel ball launching device is installed on the lifting slider 2. The lifting slider 2 is used to adjust the height of the steel ball launching device, thereby adjusting the impact force of the steel ball.

[0023] The steel ball catching mechanism is installed on the frame 1 and located above the workbench 3. The steel ball catching mechanism includes a conical funnel 7. The upper end of the conical funnel 7 is open and corresponds vertically to the steel ball dispensing device. A baffle 8 is rotatably installed at the lower end of the conical funnel 7. A high-speed motor 9 connected to the baffle 8 is installed at the lower end of the conical funnel 7. The baffle 8 is horizontally set, and the high-speed motor 9 is used to control the high-speed rotation of the baffle 8.

[0024] The steel ball falls from the conical funnel 7 and hits the tempered glass placed on the workbench 3. As the steel ball bounces up, it enters the conical funnel 7 again. The high-speed motor 9 drives the baffle 8 to rotate to the lower end of the conical funnel 7 to block the steel ball and prevent it from hitting the tempered glass a second time.

[0025] Example 2: A tempered glass strength testing device includes a frame 1, a lifting slider 2, a steel ball delivery device, and a steel ball capture mechanism. A worktable 3 is provided on the frame 1. The worktable 3 is horizontally positioned and is used to place tempered glass for impact testing. The lifting slider 2 is slidably mounted on the frame 1 and located above the worktable 3. A guide column 4 is vertically mounted on the frame 1, and the lifting slider 2 is slidably connected to the guide column 4. An electric telescopic cylinder 5 is vertically mounted on the frame 1, and the upper end of the electric telescopic cylinder 5 is fixedly connected to the lifting slider 2. The steel ball delivery device is mounted on the lifting slider 2, and the lifting slider 2 is used to adjust the height of the steel ball delivery device, thereby adjusting the impact force of the steel ball.

[0026] The steel ball launching device includes an electromagnet adsorption plate 6, on which a steel ball is adsorbed. By turning off the electromagnet, the steel ball adsorbed on the electromagnet adsorption plate 6 falls under the action of gravity.

[0027] The steel ball catching mechanism is installed on the frame 1 and located above the workbench 3. The steel ball catching mechanism includes a conical funnel 7, the upper end of which is open and corresponds vertically to the steel ball delivery device. The lower end of the lifting slider 2 is provided with a downward-facing laser emitter, which is used for positioning the conical funnel 7. A baffle 8 is rotatably provided at the lower end of the conical funnel 7. A high-speed motor 9 connected to the baffle 8 is provided at the lower end of the conical funnel 7. The baffle 8 is horizontally positioned, and the high-speed motor 9 is used to control the high-speed rotation of the baffle 8.

[0028] The steel ball falls from the conical funnel 7 and hits the tempered glass placed on the workbench 3. As the steel ball bounces up, it enters the conical funnel 7 again. The high-speed motor 9 drives the baffle 8 to rotate to the lower end of the conical funnel 7 to block the steel ball and prevent it from hitting the tempered glass a second time. The frame 1 is equipped with a lifting frame 10, which is connected to a protective cover 11 that covers the workbench 3. The protective cover 11 prevents the tempered glass from splashing during the impact of the steel ball.

[0029] The working principle is as follows:

[0030] According to the impact force to be tested, the position of the lifting slider 2 is adjusted to adapt to different impact forces. The tempered glass is placed on the worktable 3. The position of the conical funnel 7 is positioned using a laser emitter. The protective cover 11 is placed on the worktable 3. The steel ball falls from the conical funnel 7 and hits the tempered glass placed on the worktable 3. As the steel ball bounces up, it enters the conical funnel 7 again. The high-speed motor 9 drives the baffle 8 to rotate to the lower end of the conical funnel 7 to block the steel ball and prevent the steel ball from hitting the tempered glass a second time, thus ensuring the accuracy of the tempered glass impact test.
