Description

Technical Field

[0001] This utility model relates to the field of liquid quenching, and in particular to a controllable flow rate spray device for workpiece quenching. Background Technology

[0002] Controllable flow rate spray devices for workpiece quenching are mainly used for cooling treatment during the quenching process of metal workpieces. They are especially suitable for small and medium-sized steel parts and aluminum alloy parts that require basic control of cooling rate. They are widely used in industries such as machinery manufacturing, automotive parts processing, and hardware tool production. Their core function is to control the cooling rate of the workpiece by adjusting the flow rate of the spray medium, so as to avoid deformation or cracking due to excessive cooling, while ensuring that the workpiece has basic hardness and microstructure properties after quenching. Currently, such devices on the market mainly consist of a water tank, a pump, a control valve, and a spray pipeline. The pump provides the power to deliver water or ordinary quenching liquid from the water tank into the pipeline. After the flow rate is adjusted by the flow control valve, the medium is evenly sprayed onto the surface of the high-temperature workpiece through the nozzle to achieve controllable and uniform cooling and ensure the quenching quality of the workpiece. Existing controllable flow rate spray devices for workpiece quenching waste cooling medium during use, polluting the environment and wasting resources. Therefore, a controllable flow rate spray device for workpiece quenching is proposed to solve the above problems. Utility Model Content

[0011] This utility model has the following beneficial effects: 1. In this utility model, the cooling medium after spraying is guided and collected, filtered to remove impurities, and then returned to the water tank.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-5 The present invention provides an embodiment of a controllable flow rate spraying device for workpiece quenching, comprising a processing container 1, a spraying mechanism 11 disposed outside the processing container 1, a control component 18 fixedly connected to the outside of the processing container 1, inclined grooves 14 formed around the bottom of the processing container 1, a circular hole 15 formed at the center of the bottom of the processing container 1, a filter screen 16 fixedly connected inside the circular hole 15, a drainage pipe 17 fixedly connected to the bottom of the processing container 1, a water tank 4 fixedly connected to the end of the drainage pipe 17 away from the processing container 1, and a main water pipe 5 fixedly connected to the outside of the water tank 4.

[0017] The processing container 1 serves as the core bearing space for workpiece quenching, used to place the workpiece to be processed. The external spray mechanism 11 provides a cooling medium spray channel for the workpiece. The control component 18 serves as the control center of the entire device, coordinating and regulating the operating status of each component. The inclined groove 14 at the bottom of the processing container 1 adopts an inclined structure design, which can guide the sprayed cooling medium to converge towards the circular hole 15 at the bottom center, avoiding the accumulation of medium residue at the bottom of the container. The filter screen 16 inside the circular hole 15 can filter the returning cooling medium, intercepting metal chips, impurities, etc. generated during the quenching process, preventing subsequent pipelines and components from being blocked, and ensuring the stable operation of the device. The filtered cooling medium flows into the water tank 4 through the drainage pipe 17 for recycling and storage. The main water pipe 5 serves as the main channel for medium transportation, providing a continuous supply of cooling medium to the spray mechanism 11.

[0018] Reference Figures 1-5A water pump 6 is fixedly connected to the outside of the main water pipe 5. Two branch water pipes 7 are fixedly connected to the end of the main water pipe 5 away from the water tank 4. A control valve 8 is fixedly connected to the outside of the branch water pipe 7. A water pressure gauge 9 is fixedly connected to the outside of the branch water pipe 7. Multiple nozzles 10 are fixedly connected to the outside of the branch water pipe 7. Cooling medium can be input to the end of the branch water pipe 7 away from the main water pipe 5.

[0019] The water pump 6 provides power for the circulation of the cooling medium, driving the cooling medium stored in the water tank 4 to be transported along the main water pipe 5 to the branch water pipe 7. The two branch water pipes 7 realize the diversion and transportation of the medium. The control valve 8 can adjust the flow rate of the medium in the corresponding branch water pipe 7, thereby precisely controlling the spray flow rate to meet the different requirements of cooling speed during the quenching of different workpieces. The water pressure gauge 9 monitors the medium pressure in the branch water pipe 7 in real time, making it easy for operators to intuitively grasp the flow rate status and make timely adjustments. Multiple nozzles 10 serve as the actuators for medium spraying, converting the cooling medium in the branch water pipe 7 into a uniform spray of water. The cooling medium inlet reserved at the end of the branch water pipe 7 away from the main water pipe 5 can realize the rapid replenishment of external medium when the medium in the water tank 4 is insufficient or when a special cooling medium needs to be replaced, improving the flexibility of the device.

[0020] Reference Figures 1-5 The bottom of the processing container 1 is fixedly connected to four support legs 2, and the end of the support legs 2 away from the processing container 1 is fixedly connected to a base plate 3.

[0021] The four support legs 2 are symmetrically distributed and jointly bear the weight of the processing container 1, raising the processing container 1 to a certain height. This not only provides installation and operating space for components such as the bottom inclined groove 14 and drainage pipe 17, avoiding direct contact between these components and the ground, which could cause wear or blockage, but also ensures the levelness of the inside of the processing container 1 and prevents uneven distribution of the cooling medium inside the container. The bottom plate 3 at the bottom of the support legs 2 increases the contact area between the device and the ground, effectively distributing the overall weight and improving the stability of the device when it is placed.

[0022] Reference Figures 1-5 The water tank 4 is fixedly connected to the top of the base plate 3, and the water pump 6 is fixedly connected to the top of the base plate 3.

[0023] The base plate 3 provides a unified installation reference surface for the water tank 4 and the water pump 6, ensuring that their installation positions are relatively fixed and flat, reducing relative displacement caused by vibration during operation, and preventing loosening of connecting pipes. At the same time, the close installation of the water tank 4 and the water pump 6 on the base plate 3 shortens the transportation path of the cooling medium from the water tank 4 to the water pump 6, reduces pressure loss during medium flow, improves medium circulation efficiency, and allows the spray mechanism 11 to quickly obtain a stable pressure of cooling medium, ensuring timely response of the controllable flow rate spray function.

[0024] Reference Figures 1-2The control component 18 has multiple buttons 19 externally fixedly connected to it, and multiple switches 20 externally fixedly connected to it.

[0025] Multiple buttons 19 correspond to different function parameter settings, such as spray flow rate adjustment, spray time setting, and medium circulation mode switching. Operators can input control commands by pressing the corresponding button 19. Multiple switches 20 are used to control the start and stop of each core component, such as the start and stop of water pump 6 and the on / off switching of branch water pipe 7, to achieve direct control of the device's operating status. After receiving the parameter commands from the buttons 19 and the start and stop signals from the switches 20, the control component 18 processes the signals and transmits them to the corresponding execution components, thereby achieving automated and precise control of the entire spray quenching process and meeting the usage requirements under different working conditions.

[0026] Reference Figure 5 Two support columns 12 are fixedly connected to the inner walls on both sides of the processing container 1, and a clamp 13 is fixedly connected to the end of the support column 12 away from the processing container 1.

[0027] The support column 12 provides a stable mounting support for the clamp 13, enabling it to be accurately positioned in a preset position inside the processing container 1. It can clamp and fix the workpiece from both sides or both ends, ensuring that the workpiece maintains a stable posture during the quenching process and preventing the workpiece from shifting or shaking due to the impact of the spray water or the flow of the medium. Through the fixing effect of the clamp 13, the workpiece can be placed in the optimal spraying area inside the processing container 1, ensuring that the cooling medium sprayed by the subsequent nozzles 10 can act evenly on the surface of the workpiece, improving the consistency and quality stability of the quenching process.

[0028] Reference Figures 1-4 Multiple nozzles (10) can evenly cover the workpiece area.

[0029] The arrangement of multiple nozzles 10, combined with the spray angle and range design of the nozzles 10 themselves, ensures that the spray areas of all nozzles 10 are interconnected and cover the surface of the workpiece in the processing container 1 without any dead angles. This uniform coverage design ensures that all parts of the workpiece are sprayed with cooling medium simultaneously during the quenching process, and that the medium flow rate and contact amount are consistent in each part. This avoids defects such as deformation and cracking of the workpiece due to excessively fast or slow local cooling rates. At the same time, with the precise control of the flow rate by the control valve 8, the quenching hardness, toughness and other performance indicators of the workpiece can be precisely controlled to meet the quenching process requirements of different workpieces.

[0030] Working principle: The spray flow rate, spray time, and media circulation mode are set by the button 19 on the outside of the control component 18. Then, the device is started by the switch 20 on the outside of the control component 18. At this time, the water pump 6 fixed on the top of the base plate 3 starts to work, and the cooling medium in the water tank 4, which is also fixed on the top of the base plate 3, is transported along the main water pipe 5 to two branch water pipes 7. During the transportation process, the water pressure gauge 9 on the outside of the branch water pipe 7 monitors the pressure of the medium in the pipe in real time. The operator can adjust the flow rate of the medium in the pipe according to the quenching requirements by using the control valve 8 on the outside of the branch water pipe 7 to accurately control the spray flow rate. The cooling medium is transported through the branch water pipe 7 to multiple nozzles 10 on its outside. The nozzles 10 are the core execution components of the spray mechanism 11. According to the preset arrangement and spray angle, the cooling medium is evenly sprayed onto the workpiece inside the processing container 1. The support columns 12 fixed on the inner walls of both sides of the processing container 1 provide stability for the clamp 13. The workpiece is fixed in place by a clamp 13, which holds the workpiece in place from both sides or ends, ensuring that the workpiece is always in the optimal spraying area within the processing container 1 and will not shift due to water flow impact. The cooling medium after spraying flows along the inclined grooves 14 around the bottom of the processing container 1 to the round hole 15 at the center of the bottom of the container. The filter screen 16 inside the round hole 15 filters out metal chips and impurities generated during quenching in the medium, preventing subsequent pipe blockage. The filtered cooling medium flows back to the water tank 4 through the drainage pipe 17 fixed at the bottom of the processing container 1 for recycling. At the same time, the four support legs 2 fixed at the bottom of the processing container 1 raise the processing container 1 to a preset height, which not only provides sufficient installation and operating space for components such as the inclined grooves 14 and drainage pipes 17, but also increases the contact area between the device and the ground through the base plate 3 connected to the bottom of the support legs 2, effectively distributing the overall weight of the device and ensuring the stable operation of the device throughout the quenching spraying process.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
