Description

Technical Field

[0001] This utility model relates to the field of thermal testing technology, specifically a temperature equalization device for testing heat treatment furnaces. Background Technology

[0002] Currently, testing departments in the industry generally use conventional methods when conducting various tests on resistance furnaces or gas-fired heat treatment furnaces. However, the actual test results exhibit significant random variations and poor data reproducibility. This can easily lead to situations where the furnace temperature uniformity test passes, but the actual heat treatment effect on the workpiece is poor. During testing, thermocouples placed in the furnace space are bound to a temperature measuring frame with iron wire, and the measuring points are suspended in the air. The actual temperature being measured is the air temperature at the corresponding location in the furnace. This testing method has certain drawbacks. The thermocouple terminals have very small heat capacity, and the induced temperature is greatly affected by the air circulation inside the furnace. Furthermore, the pulse heating from the gas furnace's burner nozzle causes large instantaneous temperature changes at the test points, affecting the stability and accuracy of the collected data. This results in deviations between the test results and the actual temperature state of the metal workpiece during heat treatment. Therefore, for furnaces with high heat treatment process requirements, using similar methods can easily affect the workpiece's process requirements.

[0003] Therefore, when using a temperature equalization device, there is a tendency for the test conditions to deviate from the actual conditions, which can easily affect the product quality of heat-treated workpieces. Utility Model Content

[0004] The purpose of this invention is to provide a temperature equalization device for detecting heat treatment furnaces, so as to improve the accuracy, stability and reproducibility of furnace temperature correlation detection, and improve the similarity between the working conditions and test conditions with high requirements for heat treatment processes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature equalization device for detecting heat treatment furnaces, comprising a base and a temperature equalization chamber. A temperature equalization block is mounted on the left side of the temperature equalization chamber, and a temperature measuring thermocouple groove is mounted inside the temperature equalization block. A straight pin can be inserted into the temperature measuring thermocouple groove. A connecting block is mounted on the right side of the temperature equalization chamber, and a serrated groove is formed in the side of the connecting block. A bracket is mounted on the top of the base. One side of the bracket is a smooth plane, and the other side is designed to be serrated, with the serration matching the serrated groove. A first half-pin is connected to the connecting block on the other side of the serrated groove. A mounting slot is formed in the bottom of the first half-pin, and a mounting post is inserted into the mounting slot. A second half-pin is fixed to the bottom of the mounting post. The first half-pin and the second half-pin form an inverted trapezoidal pin.

[0006] As a further technical solution of this utility model, the insertion post and the insertion slot form a mortise and tenon connection, and a triangular plate is fixed between the outside of the bracket and the base.

[0007] As a further technical solution of this utility model, the base and the bracket are welded together, and the inner wall of the temperature equalization box is equipped with a heat insulation layer.

[0008] As a further technical solution of this utility model, a working motor is installed at the top of the temperature equalization box, and a transmission rod is connected to the output end of the working motor.

[0009] As a further technical solution of this utility model, stirring rods are installed on both sides of the transmission rod, and flow holes are evenly opened in the stirring rods. The stirring rods are staggered on both sides of the transmission rod.

[0010] As a further technical solution of this utility model, an adhesive layer is fixed to the bottom end of the base, and an anti-slip pad is fixed to the outside of the bottom end of the adhesive layer, forming an adhesive connection between the adhesive layer and the anti-slip pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the temperature uniformity device for detecting heat treatment furnaces not only improves the accuracy, stability and reproducibility of detection, but also improves the heat uniformity and bottom stability;

[0012] (1) One side of the bracket is a smooth plane, and the other side is designed to be serrated. The serrated shape and the serrated groove are compatible with each other. First, place the base and the bracket in the corresponding position in the furnace chamber of the heat treatment furnace according to the layout position. Then, put the temperature equalization box on the bracket. Adjust the height of the temperature equalization box according to the size of the furnace chamber and the layout position. After the height is adjusted to the corresponding position, use the first half pin and the second half pin to fix it. In this process, the insertion column and the insertion slot are used to form a tenon and tenon to clamp. After fixing, the temperature measuring end of the temperature measuring thermocouple is folded into a right angle and placed into the temperature measuring thermocouple groove. Finally, the temperature measuring thermocouple groove is blocked with a straight pin to prevent the temperature measuring thermocouple from falling off. With the serrated cooperation, the overall connection stability and accuracy are improved.

[0013] (2) By installing the working motor on the top of the uniform temperature box, the insulation layer forms a heat preservation working condition. After the working motor is started, it drives the transmission rod to rotate. The stirring rods are distributed on both sides of the transmission rod, and the stirring rods are evenly distributed with flow holes. In this way, a certain flow uniform heat working condition is formed during the working process, which improves the overall heat uniformity.

[0014] (3) The bracket is welded and fixed to the top of the base by welding, and a triangular plate is used to connect and fix it at the connection point, thereby improving the stability and reinforcement of the connection point. At the same time, the anti-slip pad is glued and fixed to the bottom of the base by adhesive layer, thereby improving the overall bottom stability. Attached Figure Description
