Description

Technical Field

[0001] The utility model relates to the field of testing machines, and particularly relates to a glass molding press testing machine. Background Art

[0002] Precision glass molding is a multi-process technological process involving heating, loading, annealing, and cooling. Mastering complete glass thermodynamic parameters is of great significance for deeply understanding the thermodynamic behavior of glass at each stage of molding, predicting the final molding effect, and determining reasonable process parameters. Existing testing machines that can provide high pressure cannot provide a high-temperature environment for glass. If the glass is heated externally and then placed under a testing machine that can provide high pressure, the test accuracy is not high, and the glass cannot be stabilized at the temperature required for the test. Therefore, the data obtained from the test is not accurate enough.

[0003] To solve the above problems, a glass molding press testing machine is specifically proposed. Summary of the Utility Model

[0004] The utility model aims at the problems existing above, and specifically designs a glass molding press testing machine, enabling it to perform a molding test on glass under a specific environment, detecting the performance of glass under high temperature and high pressure, and providing a basis for experimental data for the research and development of glass.

[0005] To achieve the above object, the utility model provides a glass molding press testing machine, including: a working platform, a support device, a pressurizing device, a heating device, and a graphite plate. The support device is arranged on the working platform, the heating device is placed on the working platform, the pressurizing device is installed on the support device and is located directly above the heating device. A lower pressing plate is arranged on the working platform, the lower pressing plate is placed in the heating device from below, the end of the pressurizing device is placed in the heating device from above, graphite plates are arranged at the end of the pressurizing device and on the top of the lower pressing plate, and a test piece is placed between the two graphite plates.

[0006] In the above manner, the test piece is placed on the lower pressing plate, the pressurizing rod applies high pressure to it, the heating device is provided with openings at both the top and bottom, and the lower pressing plate and the pressurizing rod clamp the test piece in the heating device through the openings, realizing the application of high pressure to the test piece in a high-temperature environment.

[0007] Further, the support device includes: a cross beam, a column, a lead screw, a sliding sleeve, and a motor. One end of the column is fixedly connected to the working platform, the cross beam is slidably connected to the column, one end of the lead screw passes through the working platform and is connected to the motor, the lead screw is located behind the column and is parallel to the column, and the cross beam is connected to the lead screw through the sliding sleeve.

[0008] In the above manner, the motor drives the lead screw to rotate, the rotation of the lead screw drives the sliding sleeve to move, the sliding sleeve drives the cross beam to move, and the supporting device on the cross beam also moves accordingly. Therefore, the movement of the end on the pressing rod is realized.

[0009] Further, the pressing device includes a hydraulic system and a pressing rod. The hydraulic system is arranged on the cross beam. The pressing rod is connected to the output end of the hydraulic system. The pressing rod can extend downward. The bottom end of the pressing rod is provided with the graphite plate and is placed in the heating device.

[0010] Further, the heating device includes a heating furnace and a heating cavity. The heating furnace is composed of two semi-cylinders with a hollowed-out middle part as the heating cavity. The two semi-cylinders are movably connected and can be opened and closed. The heating furnace is placed on the working platform, and the graphite plate is located in the heating cavity. The heating furnace can be opened and closed. When the heating furnace is opened, the graphite plate and the test piece can be installed and placed.

[0011] Further, test grooves are formed on the graphite plate. There are several test grooves and they are arranged in an array on the contact surface between the graphite plate and the test piece. The fluidity of the tested glass increases in a high-temperature environment. After pressure is applied, the glass will deform in the groove part. Different-shaped grooves are formed on the graphite plate according to different test requirements.

[0012] Further, the working platform includes a heat-insulating platform. The heat-insulating platform is installed on the working platform and is located on both sides of the lower pressing plate. The heating device is placed on the heat-insulating platform. The heat-insulating platform is made of heat-insulating material to prevent the heat of the heating furnace from being transferred to the working platform.

[0013] Further, the test grooves are formed on one of the two graphite plates. One side of each of the two graphite plates is in contact with the tested glass. Forming the grooves on one side can specifically reflect the deformation of the glass on one side during the test.

[0014] In summary, the present utility model has the following advantages and beneficial technical effects:

[0015] 1.
