Description

Technical Field

[0001] The invention relates to the technical field of electric heating presses, and in particular to a temperature uniformity control mechanism for a vacuum high-temperature electric heating press. Background Art

[0002] In many industrial production fields, such as new material research and development, electronic component manufacturing, and aerospace material processing, vacuum high-temperature electric heating presses play a vital role. They can perform high-temperature pressing on materials in a vacuum environment, which helps to eliminate the interference of air on material properties. At the same time, high temperature and high pressure conditions are used to induce specific physical or chemical changes in materials to meet the strict requirements of various high-end products for material performance.

[0003] In these application scenarios, the uniformity of the temperature inside the press is a key factor affecting product quality. If the temperature distribution is uneven, the reaction degree of each part of the material during the pressing process will be inconsistent, which will lead to local performance differences in the product, such as uneven hardness and strength. These quality defects will not only reduce the product yield and increase production costs, but may also affect the reliability and stability of the product in actual use.

Specific embodiment three

[0026] A vacuum high-temperature electric heating press is used to perform hot pressing of a composite material workpiece, which needs to be pressed under high temperature and high pressure conditions to improve its physical properties.

[0027] Equipment preparation: First, use the temperature uniformity control mechanism of the vacuum high temperature electric heating press described. Place the equipment in a suitable location, ensure that it is placed horizontally, and have enough space around it for operation and maintenance. Check whether each component is firmly installed, and connect the power supply 163 and control lines.

[0028] Steps: Place the workpiece: The moving mechanism 3 is started, and the specific operation is to control the first electric telescopic rod 302, and send a signal to the first electric telescopic rod 302 through the controller 164 to extend or shorten it, push the connecting plate 303, drive the placement plate 2 to slide on the horizontal plate 1, and accurately place the workpiece on the placement plate 2. The distance sensor 11 will monitor the position of the placement plate 2 in real time to ensure that the placement plate 2 reaches the predetermined position. At the same time, the cooperation of the sliding rod 305 and the sliding sleeve 306 ensures that the placement plate 2 moves smoothly to prevent the workpiece from shifting during the placement process.

[0029] Temperature uniformity control during heating: The electric heating plate 102 is started, and a start signal is sent to the electric heating plate 102 through the controller 164 in the circuit control mechanism 16, and the electric heating plate 102 starts to work and heats the heat-conducting fluid medium in the box 101. The heat is transferred to the hot pressing plate 103 through the evenly distributed heat-conducting plate 104, and the hot pressing plate 103 is heated.

[0030] At the same time, the position and angle adjustment procedure of the infrared temperature monitoring sensor 153 is started: First, the second electric telescopic rod 13 is started, and the second electric telescopic rod 13 is extended or shortened, driving the first adjustment mechanism 14 and the second adjustment mechanism 15 to move up and down, and adjusting the height of the infrared temperature monitoring sensor 153 to reach a suitable monitoring height to cover the entire area of ​​the hot pressing plate 103.

[0031] Next, the second motor 144 is started, and the second motor 144 drives the fourth gear 145 to rotate. Through the meshing of the gears, the third gear 143 and the first transmission rod 142 rotate accordingly, thereby driving the infrared temperature monitoring sensor 153 to rotate horizontally.

[0032] Finally, the third electric telescopic rod 154 is started, and the third electric telescopic rod 154 pushes the second transmission rod 155 to move, so that the infrared temperature monitoring sensor 153 swings with the bottom of the connecting block 152 as the center, completes the vertical angle adjustment, and realizes all-round monitoring of the hot pressing plate 103.

[0033] The temperature sensors 1018 evenly distributed inside the box 101 will monitor the temperature of the heat transfer fluid medium in real time. These temperature sensors 1018 will feed back the detected temperature data to the controller 164, and the controller 164 will compare the data differences of each temperature sensor 1018 to determine whether the temperature is uniform.

[0034] If the controller 164 finds that the temperature is uneven, it will automatically start the circulation pump 105 and the first motor 1016: The circulation pump 105 starts to work, extracts the heat transfer fluid medium from one side of the box body 101, and transports it to the other side through the pipeline, so as to realize the circulation flow of the heat transfer fluid medium and promote uniform heat distribution.

[0035] The first motor 1016 drives the second gear 1017, which in turn drives the first gear 1015, the worm 1014, the worm wheel 1013 and the rotating rod 1011 to rotate, and the stirring blade 1012 on the rotating rod 1011 starts to stir the heat transfer fluid medium, and the temperature of the heat transfer fluid medium is made more uniform through the stirring effect.

[0036] The controller 164 will continue to receive data from the infrared temperature monitoring sensor 153 and the temperature sensor 1018. Once the temperature distribution reaches a uniform state, the first motor 1016 and the circulation pump 105 will be automatically turned off to stop the stirring and circulation operations of the heat transfer fluid medium.

[0037] Hot pressing: When the temperature is evenly distributed, the controller 164 sends a start signal to the hydraulic telescopic rod 7, and the hydraulic telescopic rod 7 starts to work and extends downward. The hydraulic telescopic rod 7 drives the moving plate 8 to slide downward along the column 5, and the moving rod 602 and the moving sleeve 601 ensure the vertical movement of the moving plate 8. The moving plate 8 drives the supporting plate 9 and the hot pressing mechanism 10 to move downward as a whole, and the hot pressing plate 103 of the hot pressing mechanism 10 performs hot pressing processing on the workpiece placed on the placing plate 2.

[0038] Process monitoring and adjustment: During the hot pressing process, the infrared temperature monitoring sensor 153 and the temperature sensor 1018 continue to monitor the temperature. If temperature fluctuations or unevenness occur, the controller 164 can restart the circulation pump 105 and the first motor 1016 according to a preset program to adjust the temperature to ensure temperature uniformity throughout the hot pressing process.

[0039] Heat pressing completed: After the hot pressing operation is completed, the hydraulic telescopic rod 7 retracts, driving the hot pressing mechanism 10 to rise, and the moving mechanism 3 moves the placement plate 2 to a suitable position, so that the operator can take out the processed workpiece.

[0040] The working principle of the present invention is as follows: the electric heating plate 102 is started, and the electric heating plate 102 works to heat the heat-conducting fluid medium. The heat-conducting fluid medium cooperates with the heat-conducting plate 104 to transfer heat to the hot pressing plate 103, so as to heat the hot pressing plate 103. The use position and monitoring angle of the infrared temperature monitoring sensor 153 are adjusted. First, the second electric telescopic rod 13 is started, and the second electric telescopic rod 13 works to drive the first adjustment mechanism 14 and the second adjustment mechanism 15 to move up and down, so as to adjust the use height of the infrared temperature monitoring sensor 153. After the height is adjusted, the second motor 144 is started first, and the second motor 144 works to drive the fourth gear 145 to rotate, and the fourth gear 145 drives the third gear 143 to rotate, and the third gear 143 drives the fourth gear 145 to rotate. A transmission rod 142 rotates, and the first transmission rod 142 drives the second adjustment mechanism 15 and the infrared temperature monitoring sensor 153 to rotate, so as to adjust the horizontal angle of the infrared temperature monitoring sensor 153, and then start the third electric telescopic rod 154, and the third electric telescopic rod 154 drives the second transmission rod 155 to move, and the second transmission rod 155 drives the infrared temperature monitoring sensor 153 to swing with the bottom of the connecting block 152 as the center of the circle, so as to adjust the vertical angle of the infrared temperature monitoring sensor 153. Through multi-directional adjustment, it is ensured that the infrared temperature monitoring sensor 153 can fully monitor the hot pressing plate 103, and the infrared temperature monitoring sensor 153 performs real-time visual monitoring of the temperature distribution, so as to timely discover and adjust the temperature unevenness. The temperature of the heat transfer fluid medium in the box 101 is monitored in real time through the temperature sensors 1018 evenly distributed inside the box 101, and the differences between the monitoring values ​​of each temperature sensor 1018 are compared to determine whether the temperature is evenly distributed. The two temperature monitoring methods can achieve accurate monitoring. When the infrared temperature monitoring sensor 153 or the temperature sensor 1018 detects that the temperature is unevenly distributed, the controller 164 automatically controls the first motor 1016 and the circulating pump 105 to work. The circulating pump 105 works to circulate the heat transfer fluid medium in the inner cavity of the box 101, thereby improving the uniformity of heat distribution on the hot pressing plate 103. The first motor 1016 drives the second gear 1017 to rotate, and the second gear 1017 The first gear 1015 is driven to rotate, and the first gear 1015 drives the worm 1014 to rotate. The worm 1014 drives the worm wheel 1013 to rotate. The worm wheel 1013 drives the rotating rod 1011 to rotate. The rotating rod 1011 drives the stirring blade 1012 to rotate. The evenly distributed stirring blade 1012 stirs and mixes the heat transfer fluid medium, thereby further improving the uniformity of heat distribution on the hot pressing plate 103. When the temperature is evenly distributed, the controller 164 automatically controls the first motor 1016 and the circulating pump 105 to stop working, and starts the hydraulic telescopic rod 7. The hydraulic telescopic rod 7 drives the movable plate 8 to move downward, and the movable plate 8 drives the support plate 9 and the hot pressing mechanism 10 to move downward. The hot pressing mechanism 10 cooperates with the placement plate 2 to perform hot pressing processing on the workpiece.
