Description

Technical Field

[0001] This utility model belongs to the field of metal material heat treatment testing technology, specifically relating to an integrated digital control end-effector quenching system. Background Technology

[0002] With the increasing sophistication of metal surface treatment processes, metal surface hardening treatment has been widely applied in aerospace, equipment manufacturing, and other fields. The hardened surface not only reduces material usage costs but also increases the service life of metal materials. The most widely used surface hardening method for metal materials is quenching hardening. This process achieves a good hardened surface simply by heating the material to a certain temperature and then rapidly cooling it with a suitable cooling medium. Its principle mainly involves the transformation of the material's microstructure, causing the surface to form martensite, thereby achieving surface hardening. The different hardenability of different metal materials will also lead to varying degrees of surface hardening.

[0003] Before quenching a metal, a quenching test must be conducted using end-quenched samples. However, during the test, the distance from the water spray pipe to the quenching end face, the water jet height, and the water temperature cannot be precisely controlled, leading to inconsistent surface hardening of the same metal material. This, in turn, affects the judgment of the hardenability of the metal material and may result in incorrect material characterization. In the process of developing new materials, various factors such as quenching time and quenching temperature may be changed to seek the optimal hardenability of the material. Therefore, a stable quenching system is particularly important. Utility Model Content

[0004] The purpose of this invention is to provide an integrated digital control end-effector quenching system to solve the problem in the prior art where the distance from the water spray pipe to the quenching end face, the water spray height, and the water temperature cannot be precisely controlled, leading to incorrect judgment of the hardenability of the metal.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an integrated digital control end-quenching system, comprising an industrial chiller and an end-quenching device fixedly connected by an inlet pipe and a return pipe, the end-quenching device comprising a body and a top cover movably connected, an inner cylinder fixedly connected inside the body, an inlet pipe penetrating the middle of the inner cylinder, a spray pipe fixedly connected to the middle of the inlet pipe inside the inner cylinder, a water-draining disc fitted on the top of the spray pipe, an electromagnetic valve provided at the connection between the inlet pipe and the spray pipe, a drain pipe fixedly connected to the bottom of the inner cylinder, a return pipe penetrating the bottom of the body and fixedly connected to the return pipes on both sides of the body via an adapter, an inlet pipe fixedly connected to the inlet pipes on both sides of the body via an adapter, a pumping pipe fixedly connected to the return pipe, a limiting through hole opened in the middle of the top cover, a control panel fixedly connected to the front of the body, the control panel electrically connected to the electromagnetic valve via a data cable, an end-quenching sample inserted into the limiting through hole, and a limiting boss integrally formed on the top of the end-quenching sample.

[0009] Preferably, the industrial chiller is equipped with a water pump, which is fixedly connected to the return water pipe.

[0011] Preferably, the side of the main body is provided with an observation window, and a high-temperature resistant and impact-resistant glass is fixedly connected to the observation window.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 and Figure 2 The integrated digital control end-quenching system shown includes an industrial chiller 3 and an end-quenching device fixedly connected by an inlet pipe 1 and a return pipe 2. The end-quenching device includes a body 4 and a top cover 5 movably connected. An inner cylinder 6 is fixedly connected inside the body 4. The inlet pipe 1 passes through the middle of the inner cylinder 6. A water spray pipe 7 is fixedly connected to the middle of the inlet pipe 1 inside the inner cylinder 6. A water leakage disc 8 is fitted on the top of the water spray pipe 7. A solenoid valve 9 is provided at the connection between the inlet pipe 1 and the water spray pipe 7. A drain pipe 10 is fixedly connected to the bottom of the inner cylinder 6. Water pipe 2 runs through the bottom of the main body 4 and is fixedly connected to the return water pipe 2 on both sides of the main body 4 via an adapter. Water inlet pipe 1 is fixedly connected to the water inlet pipe 1 on both sides of the main body 4 via an adapter. Water pumping pipe 11 is fixedly connected to the return water pipe 2. A limiting through hole 12 is opened in the middle of the top cover 5. A control panel 13 is fixedly connected to the front of the main body 4. The control panel 13 is electrically connected to the solenoid valve 9 via a data cable. An end quenching sample 14 is inserted into the limiting through hole 12. A limiting boss 15 is integrally formed on the top of the end quenching sample 14.

[0022] To ensure the stability and accuracy of the quenching test of the end-quenched specimen 14, the distance from the water spray pipe 7 to the bottom of the end-quenched specimen 14 is set to 12-13 mm; at the same time, the solenoid valve 9 can precisely control the water outlet height of the water spray pipe 7 to 55-75 mm.

[0023] In order to ensure that the end-quenched sample 14 can be fixed in the middle of the top cover 5 and that the bottom of the end-quenched sample is inserted into the inner cylinder 6, the diameter of the limiting boss 15 is set to be larger than the diameter of the limiting through hole 12, and the diameter of the bottom of the end-quenched sample 14 is smaller than the diameter of the limiting through hole 12.

[0024] To ensure that the temperature of the circulating water supply remains constant, a water pump is installed inside the industrial chiller 3. The water pump is fixedly connected to the return water pipe 2. The water pump draws out the quenched water and then inputs it into the industrial chiller 3 to cool the water and ensure that the quenching test is carried out in a constant temperature environment.

[0025] To facilitate adding water to the industrial chiller 3, a water inlet 16 is provided on the side of the industrial chiller 3. New water is injected into the industrial chiller 3 through the water inlet 16. When there is too much water in the industrial chiller 3, the water can be discharged through the overflow outlet 17.

[0026] To facilitate real-time observation of the quenching status of the end-quenched sample 14 by staff, an observation window 18 is provided on the side of the main body 4, and a high-temperature resistant and impact-resistant glass is fixedly connected to the observation window 18.

[0027] The working process of this utility model is as follows: First, according to the requirements of the quenching test, an end-quenching sample 14 of the corresponding size is made, and the quenching end face of the end-quenching sample 14 is appropriately finely processed, preferably by fine grinding to remove burrs; Second, the end-quenching sample 14 is inserted into the inner cylinder 6 through the limiting through hole 12, and the limiting boss 15 at the top of the end-quenching sample 14 is precisely engaged with the top of the limiting through hole 12 to fix the end-quenching sample 14; Third, the industrial chiller 3 is started, and the industrial chiller 3 continuously provides quenching water to the end-quenching device. The solenoid valve 9 is opened through the control panel 13, and the end-quenching duration and water flow rate are set through the control panel 13. The water is continuously sprayed through the water spray pipe 7 to quench the end-quenching sample. The bottom of sample 14 is sprayed and quenched. When the set time is reached, the solenoid valve 9 is controlled to cut off the power supply in time and stop the quenching of the sample 14. Secondly, during the quenching process, the oxide scale generated will fall on the surface of the water leakage disc 8 to ensure the smooth flow of water and prevent the oxide scale from accumulating at the bottom of the inner cylinder 6 and forming a blockage, which would affect the normal use of the end quenching device. Finally, the quenched water falls into the bottom of the inner cylinder 6 through the water leakage disc 8 and enters the bottom of the body 4 through the water drop pipe 10. The water pump in the industrial chiller 3 pumps the water at the bottom of the body 4 back into the industrial chiller 3 through the return water pipe 2. After cooling it, it is injected back into the water inlet pipe 1 to form circulating water, which is convenient for subsequent quenching tests.

[0028] The above description is only a preferred embodiment of the present utility model. The technical solution of the present utility model is not limited thereto. It should be noted that for those skilled in the art, under the technical teachings provided by the present utility model and as common knowledge in the field, other equivalent modifications and improvements can be made, which should also be considered within the protection scope of the present utility model.
