Description

[0002] A mandrel is an important tool for manufacturing metal or plastic parts with complex shapes and is widely used in fields such as casting, injection molding, and mold manufacturing. For the processing of steel mandrels, quenching is a crucial step aimed at improving its hardness and strength. Quenching heats the steel to the critical temperature and then rapidly cools it, causing its microstructure to transform into a harder martensite phase, thereby improving wear resistance and fatigue resistance and extending the service life in high-strength environments.

[0003] During the quenching process, a cooling barrel and a coolant are usually used for rapid cooling. The steel mandrel heated to the critical temperature is placed into the cooling barrel by a tool clamp, and the coolant rapidly reduces its temperature. However, in the prior art, impurities such as oxide layers generated during quenching will fall into the cooling barrel. Due to the sedimentation effect of impurities such as oxide layers, the oxide layers and other impurities will accumulate near the drain hole, affecting drainage and increasing the maintenance difficulty. This not only requires the cooling barrel to be cleaned frequently but also increases the maintenance cost and time. To solve the above problems, the technical personnel in this field have proposed a cooling device based on mandrel processing to solve the above problems. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 , an embodiment provided by the present utility model: A cooling device based on mandrel processing includes a cooling barrel 1. A filter box 2 is slidably connected inside the cooling barrel 1. A drain pipe 3 is fixedly connected to the bottom side of the cooling barrel 1. A valve is arranged outside the drain pipe 3, and the valve is a manual or electric valve.

[0026] Specifically, the cooling barrel 1 is mainly used to store the coolant to ensure that the mandrel can be quenched and cooled. The barrel body is made of corrosion-resistant material to ensure long-term use. Through the filter box 2, the impurities generated during quenching will not sink to the bottom. Sealing rings are provided at the joints between the cooling barrel 1 and the filter box 2 to prevent the cooling water from leaking. The filter box 2 slides inside the cooling barrel 1, which facilitates quick disassembly, installation, and maintenance. A drain pipe 3 is fixedly connected to the bottom side of the cooling barrel 1 to discharge the coolant in the cooling barrel 1. A manual or electric valve is used for the valve to facilitate the operator to control the discharge of the coolant.

[0027] Refer to Figures 1-3 , on both the left and right sides inside the cooling barrel 1, limiting grooves 4 are provided. A spring 5 is fixedly connected to the inner wall of the limiting groove 4. One end of the spring 5 is fixedly connected to a limiting block 6. The inner part of the limiting groove 4 is slidably connected to the outer part of the limiting block 6. One end of the limiting block 6 away from the spring 5 is fixedly connected to a clamping block 7. On both the left and right sides inside the filter box 2, clamping slots 8 are provided. The inner parts of the clamping block 7 and the clamping slot 8 are engaged with each other. One side of the limiting block 6 is fixedly connected to a pulling rope 9. The inner part of the cooling barrel 1 is slidably connected to the outer part of the pulling rope 9. The adjacent sides of the two pulling ropes 9 are fixedly connected to a rotating rod 10. The inner part of the cooling barrel 1 is rotatably connected to the outer part of the rotating rod 10.

[0028] Specifically, the limiting groove 4 can guide the limiting block 6 to slide inside the cooling barrel 1 to ensure the stable position and safe operation of the filter box 2. The spring 5 can provide a restoring force to keep the limiting block 6 return to the initial position when not stressed, ensuring that the filter box 2 is fixed. Through the engagement of the clamping block 7 and the clamping slot 8, a stable connection is formed to prevent the filter box 2 from shifting during operation and ensure the filtering effect. By connecting the limiting block 6 and the rotating rod 10 through the pulling rope 9, when the rotating rod 10 is rotated, it can drive the pulling rope 9 to move, and the pulling rope 9 can drive the limiting block 6 to move, so that the limiting block 6 can drive the clamping block 7 to move, thus facilitating the disassembly, installation, and maintenance of the filter box 2.

[0029] Refer to Figure 1 、 Figure 4 and Figure 5, One side of the cooling barrel 1 is fixedly connected with a conveying pipe 12. One end of the conveying pipe 12 is fixedly connected with a filtering pipe 14. The conveying pipe 12 and the filtering pipe 14 are connected by a first connecting flange 13. A filter net 15 is slidably connected inside the filtering pipe 14. A dismounting and installing flange 16 is fixedly connected to the outside of the filtering pipe 14. One end of the filtering pipe 14 far from the conveying pipe 12 is fixedly connected with a first connecting pipe 18. The filtering pipe 14 and the first connecting pipe 18 are connected by a second connecting flange 17. One end of the first connecting pipe 18 far from the first connecting pipe 18 is fixedly connected with a water pump 19. The output end of the water pump 19 is fixedly connected with a second connecting pipe 20. One end of the second connecting pipe 20 far from the water pump 19 is fixedly connected with a heat exchanger 21. One side of the heat exchanger 21 is fixedly connected with a return pipe 22. One end of the return pipe 22 far from the heat exchanger 21 is fixedly connected to the inside of the cooling barrel 1.

[0030] Specifically, the conveying pipe 12 is responsible for transporting the coolant from the cooling barrel 1 to the filtering pipe 14 to ensure the smooth flow of the coolant. The first connecting flange 13 is used to fix the connection between the conveying pipe 12 and the filtering pipe 14, facilitating later maintenance and cleaning. The filter net 15 is located inside the filtering pipe 14 and can effectively remove solid impurities in the coolant, extending the service life of the pipeline, the water pump 19, and the heat exchanger 21. The dismounting and installing flange 16 is fixed to the outside of the filtering pipe 14, facilitating the disassembly of the filter net 15 for cleaning or replacement, improving the maintenance efficiency. The first connecting pipe 18 connects the filtering pipe 14 and the water pump 19 to ensure that the filtered coolant can smoothly enter the water pump 19 for circulation. The second connecting flange 17 is used to fix the connection between the first connecting pipe 18 and the filtering pipe 14, facilitating installation and maintenance. The water pump 19 is responsible for pumping the coolant to the heat exchanger 21, ensuring that the flow rate and pressure of the coolant meet the processing requirements. The second connecting pipe 20 connects the water pump 19 and the heat exchanger 21. The heat exchanger 21 is used to exchange heat between the coolant and the external environment or other cooling media to improve the cooling efficiency. The return pipe 22 is responsible for returning the coolant after passing through the heat exchanger to the inside of the cooling barrel 1 to ensure the normal operation of the coolant circulation system.

[0031] Refer to Figure 1 and Figure 4 , One side of the cooling barrel 1 is fixedly connected with a mounting plate 11. The top end of the mounting plate 11 is fixedly connected with the bottom of the water pump 19. The top end of the mounting plate 11 is fixedly connected with the bottom end of the heat exchanger 21. The heat exchanger 21 is a plate heat exchanger.

[0032] Specifically, the heat exchanger 21 is designed with an efficient plate structure, having a large heat exchange area, which can effectively improve the heat exchange efficiency. The mounting plate 11 not only provides stable support but also ensures the tight connection between the water pump 19 and the heat exchanger 21, reducing vibration and noise.

[0033] Working principle: When too many impurities generated during the quenching of the mandrel in the cooling barrel 1 precipitate on the filter box 2, the rotating rod 10 is rotated to drive the two pull ropes 9 to move towards the adjacent side, thereby driving the limit block 6 to move forward, further squeezing the spring 5 to undergo elastic deformation, thereby driving the clamping block 7 to move forward, and further causing the clamping block 7 to disengage from the clamping groove 8, so that the filter box 2 can be conveniently taken out for cleaning and maintenance. Then, the clean filter box 2 is placed inside the cooling barrel 1, and the spring 5 undergoes a reset movement, thereby driving the limit block 6 to move backward, driving the clamping block 7 to move with it into the clamping groove 8, and further causing the clamping block 7 to engage with the clamping groove 8, so that the position of the filter box 2 is fixed;

[0034] In addition, when it is necessary to cool the overheated water source in the cooling barrel 1, the water pump 19 is started to operate, thereby driving the delivery pipe 12 to draw the overheated water source from the cooling barrel 1, and then flowing into the filter pipe 14 to be filtered through the filter screen 15. After filtration, it is transported to the connecting pipe 20 through the connecting pipe 18, and the overheated water source is transported to the heat exchanger 21 through the connecting pipe 20 for heat exchange, and then the cooled water source flows back into the cooling barrel 1 through the return pipe 22.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
