Description

Technical Field

[0001] This utility model relates to the field of metal quenching technology, specifically to a device for testing the effectiveness of metal heat treatment quenching. Background Technology

[0002] Quenching is a heat treatment process. Metals need to undergo quenching after heat treatment. When quenching fails, such as due to abnormalities in the spraying process at the preceding station (cracked spray tank, leaking spray pipes, etc.) leading to insufficient quenching flow for the workpiece, or due to an unreasonable quenching position for the workpiece, quenching failure can be caused by detecting the temperature of the workpiece after quenching. For example, if the temperature exceeds the limit, it indicates that the quenching was not sufficient.

[0003] In current metal quenching testing, the quenched metal is usually tested directly. However, if water, oxide scale, or other substances remain on the quenched metal workpiece, it will affect the emissivity of the object and thus affect the accuracy of temperature measurement.

[0004] Furthermore, existing displays for inspecting quenching are generally far from the workstation and lack alarm mechanisms. Workers may not be able to detect abnormal metal temperatures in time, and thus may not be able to promptly identify metals that have failed to quench. Therefore, a device for inspecting the effectiveness of metal heat treatment quenching is needed. Summary of the Invention

[0005] The present invention aims to solve the technical problems mentioned in the background section above, and provides a metal heat treatment quenching effectiveness testing device to solve the testing abnormalities caused by water or oxide scale remaining on the workpiece surface during the testing process.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a metal heat treatment quenching effectiveness testing device, including a base, a support rod fixedly installed on the upper surface of the base, a testing box fixedly installed on the top of the support rod, an installation groove opened in the testing box, a feeding roller conveyor installed in the installation groove, the upper surface of the feeding roller conveyor can convey quenched metal, and a dust removal mechanism is provided in the testing box.

[0007] In some embodiments, the dust removal mechanism includes a solenoid valve control group fixedly installed on one side of the detection box, an air duct fixedly installed inside the detection box, one end of the air duct fixedly installed on the solenoid valve control group, an air blowing head fixedly installed on the other end of the air duct, a power cord fixedly installed on the solenoid valve control group, and a power plug fixedly installed on the other end of the power cord.

[0008] In some embodiments, the solenoid valve control group includes an air blowing device, the output port of which is connected to the air blowing head via an air duct.

[0009] In some embodiments, the dust removal mechanism further includes an electric control block fixedly installed on the upper surface of the detection box. The electric control block includes a rotary motor, and a rotating rod is fixedly installed at the output end of the rotary motor. The rotating rod passes downward through the top wall of the detection box and is rotatably connected to the detection box. The lower end of the rotating rod is connected to a grinding head.

[0010] In some embodiments, an electric telescopic rod is fixedly installed at the bottom of the rotating rod along the axial direction, and a grinding head is fixedly installed at the output end of the electric telescopic rod.

[0011] In some embodiments, a connecting rod is fixedly mounted on the upper surface of the base, a control box is fixedly mounted on the top of the connecting rod, an mounting rod is fixedly mounted on the control box, and a data display screen is fixedly mounted on the top of the mounting rod.

[0012] In some embodiments, a speaker is provided inside the control box, and a strobe light is fixedly installed on the control box.

[0013] In some embodiments, an infrared thermometer is fixedly installed on the upper surface of the testing box, and a temperature measuring head is fixedly installed on the bottom of the infrared thermometer, with the temperature measuring head fixedly installed inside the testing box.

[0014] The advantages of this utility model compared with the prior art are as follows: By setting the dust removal mechanism, the quenched metal is placed on the feeding roller conveyor. When the feeding roller conveyor is started, it drives the quenched metal to move. When the quenched metal moves to the side of the air blowing head, the air blowing head will blow away the water remaining on the surface of the quenched metal. Then the quenched metal will continue to move to the bottom of the grinding head and stop. The grinding head can grind away the oxide scale on the surface of the quenched metal by rotating. This setting can make the temperature detection of the surface of the quenched metal more accurate and prevent the residual water and oxide scale on the quenched metal from affecting the temperature measurement accuracy of the quenched metal.

[0015] The advantages of this invention also lie in the following: through the setup of a control box, mounting rod, data display screen, speaker, and strobe light, the quenched metal is conveyed to the bottom of the temperature measuring head, which measures the temperature of the quenched metal and transmits the temperature data from the infrared thermometer to the control box. The temperature is displayed in real time on the data display screen, and abnormal temperatures trigger an alarm from the speaker and a strobe light. This setup allows workers to promptly detect quenched metal that has failed to quench, preventing the circulation of quenched metal that has failed to quench. At the same time, it can reduce the frequency of quality inspections by production personnel and significantly reduce workload.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] The present invention will now be described in further detail.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] The electronic components provided in this embodiment, including the feeding roller conveyor 5, infrared thermometer 7, temperature measuring head 8, control box 10, data display screen 12, and dust removal mechanism 13, are all powered by a single main power line 134. The transformer and other technical means used in the circuits are all existing and well-known technologies, and will not be elaborated upon here.

[0026] Combination Figure 1 , Figure 4 As shown, this embodiment provides a metal heat treatment quenching effectiveness inspection device, including a base 1, a support rod 2 fixedly installed on the upper surface of the base 1, a test box 3 fixedly installed on the top of the support rod 2, an installation groove 4 opened in the test box 3, a feeding roller 5 installed in the installation groove 4, an infrared thermometer 7 fixedly installed on the upper surface of the test box 3, a temperature measuring head 8 fixedly installed on the bottom of the infrared thermometer 7, and the temperature measuring head 8 fixedly installed in the test box 3.

[0027] Combination Figure 2 As shown, a connecting rod 9 is fixedly installed on the upper surface of the base 1, a control box 10 is fixedly installed on the top of the connecting rod 9, an installation rod 11 is fixedly installed inside the control box 10, a data display screen 12 is fixedly installed on the top of the installation rod 11, a dust removal mechanism 13 is provided inside the detection box 3, a speaker 14 is provided inside the control box 10, and a strobe light 15 is fixedly installed on the control box 10.

[0028] The control box 10 is communicatively connected to the infrared thermometer 7. The quenched metal 6 is placed on the feeding roller conveyor 5. The feeding roller conveyor 5 is started, and it moves the quenched metal 6 into the detection box 3. The quenched metal 6 is then conveyed to the bottom of the temperature measuring head 8, which measures the temperature of the quenched metal 6 and transmits the temperature data from the infrared thermometer 7 to the control box 10. The temperature is displayed in real time on the data display screen 12. If the temperature is abnormal, the speaker 14 will sound an alarm and the strobe light 15 will flash. This setting allows workers to promptly detect quenched metal that has failed to quench, preventing the quenched metal 6 from being circulated. At the same time, it can reduce the frequency of quality inspections by direct production personnel and significantly reduce workload.

[0029] Combination Figure 3 As shown, the dust removal mechanism 13 includes a solenoid valve control group 131 fixedly installed on one side of the detection box 3. A duct 132 is fixedly installed inside the detection box 3. One end of the duct 132 is fixedly installed on the solenoid valve control group 131, and the other end of the duct 132 is fixedly installed with an air blowing head 133. A power cord 134 is fixedly installed on the solenoid valve control group 131, and the other end of the power cord 134 is fixedly installed with a power plug 135.

[0030] In order to blow away the water remaining on the surface of the quenched metal 6, the solenoid valve control group 131 starts the air blowing device. The air blowing device generates airflow that blows out from the air blowing head 133 through the air duct 132. Then, the quenched metal 6 is placed on the feeding roller 5 and the feeding roller 5 is started. The feeding roller 5 drives the quenched metal 6 to move. When the quenched metal 6 moves to the side of the air blowing head 133, the air blowing head 133 will blow away the water remaining on the surface of the quenched metal 6.

[0031] Combination Figure 4 As shown, an electric control block 136 is fixedly installed on the upper surface of the test box 3. A rotating rod 137 is fixedly installed at the output end of the rotary motor of the electric control block 136. An electric telescopic rod 138 is fixedly installed at the bottom of the rotating rod 137. A grinding head 139 is fixedly installed at the output end of the electric telescopic rod 138.

[0032] To remove the oxide scale from the upper surface of the quenched metal 6, the quenched metal 6 will move to the bottom of the grinding head 139 and stop. First, the electric telescopic rod 138 is started to adjust the grinding head 139 to contact the upper surface of the quenched metal 6. Then, the rotary motor of the electric control block 136 is started. The rotary motor drives the rotating rod 137 to rotate, the rotating rod 137 drives the electric telescopic rod 138 to rotate, and the electric telescopic rod 138 drives the grinding head 139 to rotate. The rotation of the grinding head 139 can remove the oxide scale from the upper surface of the quenched metal 6.

[0033] When using this embodiment:

[0034] First, plug the power plug 135 into the socket to power on the device. Then, activate the air blowing device of the solenoid valve control group 131. The air blowing device generates airflow that passes through the air duct 132 and blows out from the air blowing head 133. Next, place the quenched metal 6 on the feeding roller conveyor 5 and activate the feeding roller conveyor 5. The feeding roller conveyor 5 moves the quenched metal 6. When the quenched metal 6 moves to the side of the air blowing head 133, the air blowing head 133 will blow away the water remaining on the surface of the quenched metal 6. Then, the quenched metal 6 will continue to move until it stops at the bottom of the grinding head 139. First, activate the electric telescopic rod 138 to adjust the grinding head 139 to contact the upper surface of the quenched metal 6. Then, activate the electric control block 136, which controls the rotary motor to rotate. The rotating rod 137 rotates, which in turn drives the electric telescopic rod 138 to rotate. The electric telescopic rod 138 then drives the grinding head 139 to rotate. The rotation of the grinding head 139 removes the oxide scale from the surface of the quenched metal 6. This setup allows for more accurate temperature measurement of the surface of the quenched metal 6, preventing residual water and oxide scale from affecting the temperature measurement accuracy. The quenched metal 6 is then transferred to the bottom of the temperature measuring head 8, which measures the temperature of the quenched metal 6 and transmits the temperature data from the infrared thermometer 7 to the control box 10. The temperature is displayed in real time on the data display screen 12. An abnormal temperature will trigger an alarm on the speaker 14 and a strobe light 15 to flash.

[0035] This setup allows workers to promptly identify metals that have failed to quench, preventing the circulation of such metals. It also reduces the frequency of quality inspections by production staff, significantly decreasing workload.
