[0002] Metal parts refer to a collective term for metal blocks, metal rods, metal tubes, etc. of various specifications and shapes manufactured from metal materials. In the production and processing of metal parts, some parts need to be quenched. Quenching involves heating the metal parts to above the critical temperature, holding them at that temperature for a certain time, and then cooling them at a rate greater than the critical cooling rate, thereby increasing the strength and service life of the metal. A quenching device is used in the quenching process of metal parts. A container is filled with coolant, and then the metal parts are placed on a metal mesh and immersed in the coolant for quenching.

However, due to the different shapes of metal parts, clamping is difficult and the metal parts are easy to fall off. At the same time, the clamping position does not come into contact with the oil, resulting in poor quenching effect and directly affecting the quality of the metal parts. Therefore, a quenching equipment for metal parts processing is needed to solve this problem. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-3 A quenching device for metal parts processing includes a housing 1, the interior of which is filled with coolant. A bracket 2 is fixedly connected to the upper end face of the housing 1. An electric push rod 3 is installed on the upper end face of the bracket 2. The output end of the electric push rod 3 extends to the lower part of the bracket 2 and is fixedly connected to a gantry frame 4. A roller 5 is rotatably connected to the inner wall of the gantry frame 4 through a bearing. The middle part of the roller 5 has a mesh structure. A toothed ring 8 is fixedly connected to one end of the outer wall of the roller 5. A servo motor 6 is installed on the upper end face of the gantry frame 4. A gear 7 that meshes with the toothed ring 8 is fixedly connected to the output end of the servo motor 6.

[0022] An air pump 9 is installed on the outer wall of the housing 1. The air outlet of the air pump 9 extends into the interior of the housing 1 and is connected to an air pipe 10 located at the bottom of the interior of the housing 1. Multiple evenly distributed through holes 11 are opened on the upper end face of the air pipe 10.

[0023] In this embodiment: This invention is applicable to cylindrical (or tubular) workpieces. The heated cylindrical (or tubular) workpiece is placed in roller 5 (roller 5 is made of high-temperature resistant material). The electric actuator 3 is activated, which drives the gantry frame 4 to move downward, thereby immersing the workpiece in roller 5 into the coolant. The servo motor 6 is activated, which drives the gear 7 to rotate, which in turn drives the roller 5 to rotate through the gear ring 8, causing the workpiece in roller 5 to roll and ensuring that the coolant fully contacts the workpiece. Gas (such as nitrogen or compressed air) is introduced into the air pipe 10 through the air pump 9. The bubble disturbance breaks the vapor film on the surface of the workpiece, significantly improving the cooling uniformity and preventing local overheating and media stratification. At the same time, the gas flow can also accelerate heat dissipation efficiency and reduce metal oxidation. Combined with the rotational movement of roller 5, it achieves all-round uniform quenching, thereby effectively improving the hardness of the workpiece and reducing deformation.

[0024] As a technical optimization of this utility model, a filter box 13 is provided on the outer wall of the housing 1, and a filter plate 14 is detachably connected to the inner wall of the filter box 13 by bolts. A pump body 12 with an inlet connected to the housing 1 is installed on the outer wall of the housing 1, and the outlet of the pump body 12 is connected to the filter box 13. A chiller 15 with an inlet connected to the filter box 13 is installed on the outer wall of the housing 1, and the outlet of the chiller 15 is connected to the housing 1.

[0025] In this embodiment: the coolant in the housing 1 is pumped into the filter box 13 by the pump body 12, and the impurities in the coolant are filtered by the filter plate 14. The filtered coolant enters the chiller 15 for cooling, and the cooled coolant re-enters the housing 1 for recycling.

[0026] As a technical optimization of this utility model, a temperature sensor 16 is provided on the inner wall of the box 1.

[0027] In this embodiment, the temperature sensor 16 facilitates real-time monitoring of the coolant temperature.

[0028] As a technical optimization of this utility model, the waterproof rating of the servo motor 6 is IP67.

[0029] In this embodiment, by setting the waterproof rating of the servo motor 6 to IP67, it can be ensured that it operates stably in the high humidity, water mist or short-term immersion environment of the quenching device, effectively preventing motor damage caused by coolant seepage.

[0030] As a technical optimization of this utility model, the trachea 10 is S-shaped.

[0031] In this embodiment, by setting the gas pipe 10 to an S-shape, the quenching uniformity and bubble coverage can be significantly improved.

[0032] As a technical optimization of this utility model, a controller is provided on the outer wall of the bracket 2, and the electric push rod 3, servo motor 6, air pump 9, pump body 12, chiller 15 and temperature sensor 16 are all electrically connected to the controller.

[0033] In this embodiment, an integrated controller is used to uniformly manage the electric actuator 3, servo motor 6, air pump 9, pump body 12, chiller 15 and temperature sensor 16, which can realize intelligent coordinated control of quenching process parameters, significantly improve cooling uniformity, energy efficiency and process stability, and simplify manual operation.

[0034] The working principle and usage process of this utility model are as follows: First, the heated cylindrical (or tubular) workpiece is placed into the roller 5. Then, the electric actuator 3 is activated, which drives the gantry frame 4 downwards, thereby immersing the workpiece in the roller 5 into the coolant. Next, the servo motor 6 is activated, driving the gear 7 to rotate, which in turn drives the roller 5 to rotate via the gear ring 8, causing the workpiece inside the roller 5 to roll and ensuring full contact between the coolant and the workpiece. Simultaneously, gas (such as nitrogen or compressed air) is introduced into the air pipe 10 through the air pump 9. The bubble agitation breaks the vapor film on the workpiece surface, significantly improving cooling uniformity and preventing localized overheating and media stratification. Furthermore, the gas flow accelerates heat dissipation efficiency and reduces metal oxidation. Combined with the rotational motion of the roller 5, this achieves all-around uniform quenching, effectively improving workpiece hardness and reducing deformation.

[0035] At the same time, the pump body 12 and the chiller 15 are started. The pump body 12 pumps the coolant in the tank 1 into the filter box 13. The filter plate 14 filters the impurities in the coolant. The filtered coolant enters the chiller 15 for cooling. The cooled coolant re-enters the tank 1 for recycling.
