Description

Technical Field

[0001] This utility model relates to the technical field of high and low temperature testing, and in particular to a high and low temperature testing device for testing. Background Technology

[0002] High and low temperature testing equipment is an advanced device that can accurately measure the dynamic mechanical properties of materials under high and low temperature environments. It evaluates the dynamic response of materials by generating stress waves through high-speed impact. It can accurately obtain stress-strain data of materials under extreme temperature conditions, helping researchers and engineers to better understand the behavior of materials at different temperatures, thereby optimizing product design and improving safety and reliability.

[0003] When using high and low temperature testing equipment, firstly, the sample of the material to be tested is connected to the sensor and data acquisition system. Then, a high-speed impact is applied to the sample through an electromagnetic drive device to excite the dynamic response of the material. At the same time, the high and low temperature environmental chamber is set to the required test temperature and maintained constant by the temperature control system. During the test, strain gauges or sensors record the propagation of stress waves when the sample is impacted. This data is collected in real time and transmitted to the data processing unit. Finally, based on the collected data, the analysis software calculates the dynamic mechanical property parameters of the material, such as elastic modulus, yield strength, and fracture toughness, thereby evaluating the material's performance under different temperature conditions.

[0004] Some existing high and low temperature testing equipment suffers from insufficient environmental adaptability, only capable of conducting tests at room temperature. This fails to meet the demands of dynamic mechanical property testing of materials under extreme high and low temperature environments. The reasons for this are threefold: first, the lack of an efficient high and low temperature environment simulation system makes it difficult to quickly and stably regulate and maintain temperature during testing; second, the temperature control module and impact loading system of existing equipment are independent, compromising the accuracy and reliability of test data during dynamic loading in high and low temperature environments; and third, uneven temperature field distribution during testing leads to uneven heating or cooling of materials, severely affecting the accuracy of test results. Therefore, this paper proposes a new high and low temperature testing equipment to address these issues. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 One embodiment of this utility model is a high and low temperature testing device, including a main unit box 1. The main unit box 1 is the outer shell of the entire high and low temperature testing device, which plays a supporting and protective role. A door 2 is fixedly connected to the front of the main unit box 1 to seal the internal space of the main unit box 1 and prevent external environmental factors from interfering with the internal testing environment. A high and low temperature mechanism is provided inside the main unit box 1, and an automatic pop-out mechanism is provided inside the main unit box 1.

[0034] The high and low temperature mechanism includes a high and low temperature plate 3, which has a high specific heat capacity and good heat conduction uniformity, enabling it to quickly and evenly transfer heat and ensure that the test sample is in a stable temperature environment. A high and low temperature cavity 4 is opened in the internal space region of the high and low temperature plate 3. In order to ensure the uniform temperature distribution inside the cavity, a temperature sensor is provided to monitor the temperature change inside the cavity in real time and feed the temperature signal back to the temperature control unit interface 9 so as to adjust the fluid flow rate or temperature in the temperature control flow channel pipe ring 5 of the high and low temperature plate 3 in a timely manner, thereby achieving precise control of the temperature inside the cavity. Adjustment components are fixedly connected to the left and right sides of the internal space region of the high and low temperature cavity 4 to adjust the temperature of the high and low temperature plate 3. By controlling the flow rate, temperature and other parameters of the fluid flowing through the pipe ring, the high and low temperature plate 3 is heated or cooled, thereby achieving the purpose of regulating the temperature inside the high and low temperature cavity 4.

[0035] Insulating ceramic buckets 6 are fixedly connected to the left and right sides of the adjustment component. The insulating ceramic buckets 6 have good insulation and high temperature resistance, which can effectively prevent the conduction of current, ensure the safe operation of the equipment, and enhance the stability of the entire high and low temperature mechanism. An electrical contact 7 is fixedly connected to one side of the insulating ceramic bucket 6, which can accurately transmit the electrical signal or control current output by the temperature control unit to the temperature control flow channel coil 5, so as to achieve precise control of the temperature of the high and low temperature plate 3. A heat insulation plate 8 is fixedly connected to one side of the electrical contact 7, which reduces the heat exchange between the high and low temperature cavity 4 and the external environment, and improves the temperature holding capacity and energy utilization efficiency of the high and low temperature cavity 4.

[0036] A temperature control unit interface 9 is fixedly connected to the top space of the heat insulation plate 8. It is responsible for transmitting the temperature signal in the high and low temperature chamber 4 to the temperature control unit and transmitting the control signal of the temperature control unit to the high and low temperature mechanism, thereby realizing the automatic adjustment of the temperature in the high and low temperature chamber 4. Pressure monitoring 10 is fixedly connected to the left and right sides of the heat insulation plate 8 to monitor the pressure change of the high and low temperature plate 3 during the test in real time. When the pressure exceeds the set value, an alarm signal is issued in time to remind the test personnel to take corresponding measures to prevent the equipment from being damaged due to excessive pressure. The high and low temperature plate 3 is fixedly connected to the inside of the main unit box 1.

[0037] The automatic ejection mechanism includes a telescopic rod 11, which is responsible for pushing the specimen support plate 14 outward after the test is completed or in an emergency. The telescopic rod 11 is driven by the elastic potential energy of the spring 12 to achieve the automatic ejection of the test sample. Springs 12 are sleeved on the left and right sides of the telescopic rod 11. When the telescopic rod 11 is triggered, the springs 12 are compressed to store elastic potential energy, and then release the energy to push the specimen support plate 14 outward. Connecting blocks 13 are fixedly connected to the left and right sides of the telescopic rod 11, which serve to transmit the force of the spring 12 and connect the specimen support plate 14.

[0038] The top left and right sides of the connecting block 13 are fixedly connected to the specimen support plate 14, which is used to place the test sample. It is the direct target of the automatic pop-out mechanism and is used to cooperate with the limit block 16 on the box door 2 to ensure that the specimen support plate 14 is in a fixed position during the test and to prevent accidental movement. The outer left side of the telescopic rod 11 is fixedly connected to the inner left and right sides of the main unit box 1.

[0039] Reference Figures 3 to 4The adjustment component includes a temperature control flow channel ring 5, which is externally fixed to the outside of the high and low temperature plate 3. The inside of the insulating ceramic bucket 6 is internally fixed to the outside of the temperature control flow channel ring 5. An adapter groove 15 is provided on the right side of the specimen carrier plate 14 for cooperating with the limiting block 16 on the door 2. During the test, the limiting block 16 is inserted into the adapter groove 15 to fix the specimen carrier plate 14 inside the main unit box 1. When the automatic pop-out mechanism is triggered, the limiting block 16 disengages from the adapter groove 15, and the specimen carrier plate 14 pops outward under the force of the spring 12.

[0040] A limiting block 16 is fixedly connected to the left side of the inner wall of the box door 2. It is used to fix the position of the specimen carrier plate 14 during the test. It matches the adapter groove 15 on the specimen carrier plate 14 and can be tightly inserted into the adapter groove 15 to prevent the specimen carrier plate 14 from moving. The limiting block 16 is fixedly connected to the outside of the adapter groove 15. The left and right sides of the inner wall of the main unit box 1 are fixedly connected to the slide rail 17, which is used to provide guidance and support for the sliding of the specimen carrier plate 14. The internal space area of ​​the slide rail 17 is provided with a sliding groove 18, which is the track for the sliding of the specimen carrier plate 14.

[0041] Reference Figures 1 to 2 The slide groove 18 has a sliding block 19 inside, which is used to connect with the outer wall of the specimen support plate 14 to realize the sliding of the specimen support plate 14. The slide groove 18 has a slide rail outlet 20 on the right side inside, which is the channel for the specimen support plate 14 to detach from the slide rail body 17 when it pops out. The outer wall of the sliding block 19 is fixedly connected to the left and right sides of the outer wall of the specimen support plate 14.

[0042] A touch screen 21 is fixedly connected to the front of the enclosure door 2 to display the working status, temperature, pressure and other parameters of the equipment, and to provide a human-machine interface. A control function area 22 is fixedly connected to the front of the enclosure door 2 to provide manual control and emergency operation of the equipment. A power switch 23 is fixedly connected to the front of the enclosure door 2 to control the power supply of the equipment. The specimen support plate 14 is externally slidably connected to the inside of the main unit box 1.

[0043] Working principle: The high and low temperature plate 3 is equipped with a temperature sensor in the high and low temperature cavity 4 to monitor the temperature change in real time and feed the temperature signal back to the temperature control unit interface 9. The temperature control flow channel ring 5 in the adjustment component heats or cools the high and low temperature plate 3 by controlling the fluid flow rate, temperature and other parameters of the fluid flowing through the ring, so as to regulate the temperature inside the high and low temperature cavity 4. The insulating ceramic barrel 6 ensures the safe operation of the equipment. The electrical contact 7 transmits the electrical signal or control current output by the temperature control unit to the temperature control flow channel ring 5 to achieve precise temperature control. The heat insulation plate 8 reduces the heat exchange between the high and low temperature cavity 4 and the outside. The temperature control unit interface 9 realizes the automatic adjustment of the temperature inside the high and low temperature cavity 4. The pressure monitoring 10 monitors the pressure change of the high and low temperature plate 3 in real time during the test and issues an alarm signal when the pressure exceeds the set value.

[0044] By fixing the specimen carrier plate 14 inside the main unit box 1, and with the sliding block 19 on the outer wall of the specimen carrier plate 14 in the slide groove 18 of the slide rail body 17, the slide rail body 17 provides guidance and support. When the test is completed, the automatic ejection mechanism is triggered. The springs 12 on both sides of the telescopic rod 11 are first compressed to store elastic potential energy. Then, the springs 12 release energy to drive the telescopic rod 11 to push the connecting block 13. The connecting block 13 drives the specimen carrier plate 14, causing the limiting block 16 to disengage from the adapter groove 15. Under the action of the spring 12, the specimen carrier plate 14 slides along the slide groove 18 and ejects from inside the main unit box 1, realizing the automatic ejection of the test sample.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
