Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary testing equipment for resistance heat treatment furnaces, specifically relating to a furnace temperature performance testing device for resistance heat treatment furnaces. Background Technology

[0002] In modern manufacturing, heat treatment is a crucial process widely used in machinery, aerospace, automotive, shipbuilding, and many other fields. By heating, holding, and cooling metallic materials, their microstructure can be altered, thereby improving their mechanical properties, hardness, toughness, wear resistance, and many other characteristics to meet the requirements of various engineering components. The temperature of the resistance heat treatment furnace is one of the most critical process parameters in the entire heat treatment process. The accuracy, uniformity, and stability of the furnace temperature directly determine the quality of the workpiece after heat treatment. Improper furnace temperature control can lead to quality problems such as uneven hardness, internal structural defects, and excessive deformation, seriously affecting product performance and service life. Therefore, to quickly and accurately understand the furnace temperature performance of resistance heat treatment furnaces, regular performance tests are required to ensure the stability and reliability of the heat treatment production process, reduce product defects caused by furnace temperature issues, improve production efficiency, and reduce production costs. Utility Model Content

[0003] The purpose of this invention is to provide a device for detecting the furnace temperature performance of a resistance heat treatment furnace, so as to achieve accuracy and stability in detecting the furnace temperature performance of the resistance heat treatment furnace, while shortening the detection time and improving the customer's production efficiency and product quality.

[0004] To achieve the above objectives, the technical solution of this utility model is: a resistance heat treatment furnace temperature performance testing device, comprising a resistance heat treatment furnace, a test platform on the top of the resistance heat treatment furnace, a testing instrument on the top of the test platform, folding rods rotatably connected to the four corners of the bottom of the test platform, a plurality of threaded holes on the top of the resistance heat treatment furnace, a thermal sensor inserted into the threaded hole, a fixing pin inserted into the threaded hole, the thermal sensor being fixed in the threaded hole by the fixing pin, and the testing instrument being connected to the thermal sensor by a compensating wire.

[0005] Preferably, the test platform is provided with tension rods on both sides, and limit grooves are provided on the tension rods. Support rods are rotatably connected to the four corners of the top of the test platform. The support rods are arranged in a crisscross manner, and the other end of the support rod is connected to the tension rod by a fixing bolt. The fixing bolt can move within the limit groove.

[0006] Preferably, the end of the heat sensor that extends into the resistance heat treatment furnace is fitted with a ceramic sleeve.

[0007] The present invention has the following advantages over the prior art: 1. The present invention provides a resistance heat treatment furnace temperature performance testing device that performs testing at the top of the furnace chamber. Even if the temperature inside the furnace chamber is very high, testing can be performed without lowering the temperature to install a heat sensor and then raising the temperature again, thus shortening the preparation time before heating. 2. This device can ensure that the ambient temperature of the measuring instrument and the cold end of the thermal sensor is within a suitable temperature range, which fully meets the requirements of the detection method; 3. Using this device can prevent the thermal sensor from coming into contact with the heating resistance wire when it is inserted into the furnace, which could cause a short circuit and burn out the thermal sensor. 4. The utility model has a simple structure, is easy to move, and is safe and reliable during use. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] like Figures 1 to 3 The device shown is a resistance heat treatment furnace temperature performance testing device, including a resistance heat treatment furnace 1, a test platform 2 on the top of the resistance heat treatment furnace 1, a testing instrument 8 on the top of the test platform 2, and folding rods 7 rotatably connected to the four corners of the bottom of the test platform 2. The top of the resistance heat treatment furnace 1 has several threaded holes 3, and a heat sensor 4 is inserted into the threaded holes 3. A fixing pin 13 is inserted into the threaded holes 3, and the heat sensor 4 is fixed in the threaded holes 3 by the fixing pin 13. The testing instrument 8 and the heat sensor 4 are connected by a compensating wire 6.

[0014] To support the compensating wires 6 on both sides of the test platform 2 and prevent the furnace top temperature from being too high and affecting the accuracy of the measurement data, tension rods 9 are provided on both sides of the test platform 2. Limiting grooves 10 are provided on the tension rods 9. Support rods 12 are rotatably connected to the four corners of the top of the test platform 2. The support rods 12 are arranged in a crisscross pattern. The other end of the support rod 12 is connected to the tension rod 9 by fixing bolts 11. The fixing bolts 11 can move within the limiting grooves 10, stretching the tension rods 9 to both sides of the test platform 2. The fixing bolts 11 move within the limiting grooves 10, and the tension rods 9 unfold to both sides to support the compensating wires 6, so that the compensating wires 6 and the resistance heat treatment furnace 1 are at a certain height, preventing the temperature of the compensating wires 6 from being too high and affecting the test results. When testing is not required, the tension rods 9 can be retracted to both sides of the test platform 2.

[0015] To prevent the thermal sensor 4 from not contacting the resistance wire inside the furnace when it is inserted into the resistance heat treatment furnace 1, and to avoid short circuits, a ceramic sleeve 5 is fitted onto the end of the thermal sensor 4 that extends into the resistance heat treatment furnace 1.

[0016] The working process of this utility model is as follows: First, select an appropriate number of thermal sensors 4 according to the measurement needs, fit ceramic sleeves 5 on the ends of thermal sensors 4, remove the pre-installed bolts on the threaded holes 3, and then insert the corresponding thermal sensors 4 into the furnace chamber of the resistance heat treatment furnace 1 through the threaded holes 3. When the thermal sensors 4 extend to a fixed length, insert the fixing pins 13 into the threaded holes 3 to fix the thermal sensors 4; Second, place the test platform 2 on top of the resistance heat treatment furnace 1, open the folding rod 7 to support the test platform 2, and place the testing instrument 8 above the test platform 2; Third, pull... The tension rods 9 on both sides of the test bench 2 and the fixing bolts 11 at the ends of the support rods 12 can move within the limiting grooves 10. After reaching the limit position, the tensioning stops. One end of the compensation wire 6 is connected to the test instrument 8, and the other end is connected to the thermal sensor 4. The compensation wire 6 is placed on the tension rod 9, so that the compensation wire 6 and the resistance heat treatment furnace 1 are kept at a certain height to prevent the temperature of the compensation wire 6 from being too high and affecting the test results. Finally, the resistance heat treatment furnace 1 is heated to the set temperature. After maintaining the temperature for a certain period of time, the test instrument 8 is started to test the furnace temperature performance in the furnace chamber and the data after the test is recorded.
