Description

Technical Field

[0001] This utility model relates to the field of machine tool castings, specifically a cooling device for manufacturing machine tool castings. Background Technology

[0002] Cooling devices for machine tool casting manufacturing typically refer to cooling devices used during the production of machine tool castings. These devices are designed to control the temperature of machine tool castings to ensure that the castings do not overheat during processing. In some cases, machine tool castings require heat treatment, such as quenching and tempering. During and after these heat treatment processes, cooling devices are needed to cool the castings to achieve the required microstructure and performance requirements. Chinese Patent No. CN222718438U discloses a cooling device for machine tool casting manufacturing, including a main block. A liquid storage block is fixedly connected to one side of the main block. Slots are provided on the inner side of the main block near the front and back. A limit rod is fixedly connected to the top of the main block. A threaded rod is bearing-connected to the top of the main block away from the limit rod. A top plate is bearing-connected to the top of the threaded rod. The bottom of the top plate is fixedly connected to the limit rod. A fixed plate is bearing-connected to the inner side of the main block near the top. A floor pad is provided on the inner side of the main block near the bottom. A collection box is mounted on the top of the floor pad.

[0003] The aforementioned cooling device for manufacturing machine tool castings, by incorporating a fixed disc and a first gear, facilitates uniform cooling of the entire casting surface, preventing thermal stress concentration caused by excessively high or low local temperatures, and promoting the refinement and uniform distribution of metal grains. However, the aforementioned cooling device for manufacturing machine tool castings still has the following drawbacks in practical use:

[0004] Since the casting itself is at a high temperature after heat treatment, and the aforementioned cooling device for machine tool casting manufacturing cools by spraying without any protection, the water sprayed on the casting will heat up rapidly at the high temperature of the casting. Some of the water will evaporate at the high temperature, and the rest will splash out in all directions, which may burn the workers. Therefore, a cooling device for machine tool casting manufacturing is proposed to address the above problems. Utility Model Content

[0026] Please see Figures 1-4 As shown, a cooling device for manufacturing machine tool castings includes a cooling box 1 for cooling the manufactured machine tool castings. Side plates 2 are fixedly installed on the upper parts of opposite sides of the cooling box 1. Mounting holes 3 are opened on both side plates 2. Grid plates 4 are fixedly installed in both mounting holes 3. A top plate 20 is fixedly installed on the upper end of both side plates 2. Ventilation holes 5 are opened on the upper surface of the top plate 20. Fans 6 are installed in the ventilation holes 5. Mounting strips 17 are lifted and installed on both sides of the cooling box 1. A hollow placement plate 7 for placing machine tool castings is slidably installed between the two mounting strips 17. Pull rings 11 are fixedly installed on the upper surfaces of both ends of the hollow placement plate 7.

[0027] Through the design of side plate 2, grid plate 4, ventilation hole 5, fan 6, hollow placement plate 7, pull ring 11, mounting strip 17 and top plate 20, when the heat-treated casting needs to be cooled, coolant is injected into the cooling box 1, the hollow placement plate 7 is first raised to the top of the cooling box 1, and then the hollow placement plate 7 is pulled out by the pull ring 11, so that the casting can be placed on the hollow placement plate 7. Finally, the hollow placement plate 7 is pushed back to its original position and lowered into the cooling box 1 for cooling. The cooperation of side plate 2 and top plate 20 has a protective function. After cooling, the hollow placement plate 7 is raised to the top of the cooling box 1 and the fan 6 is turned on to work in the ventilation hole 5, so that the moisture on the casting can be dried quickly. The design of grid plate 4 on side plate 2 facilitates ventilation and cooling of the casting when the fan 6 is working, ensuring the safety of the workers and improving the protection of the workers.

[0028] Among them, a fan guard 19 for protecting the fan 6 is fixedly installed on the top plate 20 at the ventilation hole 5.

[0029] To improve the protection of fan 6, the fan guard 19 is designed to block some external debris from entering the ventilation hole 5 and causing damage to fan 6, thus improving the protection of fan 6.

[0030] In this case, slide rails 10 are fixedly installed on both opposite sides of the cooling box 1, and the two opposite sides of the two mounting strips 17 are slidably connected to the opposite sides of the cooling box 1 through the slide rails 10.

[0031] In order to facilitate the lifting and lowering of the mounting strip 17 in the cooling box 1, the slide rail 10 is designed to not only facilitate the lifting and lowering of the mounting strip 17 in the cooling box 1, but also to limit the mounting strip 17 and improve the stability of the hollow placement plate 7 during use.

[0032] Among them, multiple pads 9 are fixed in a linear array evenly distributed on the upper surface of the hollow placement plate 7.

[0033] In order to increase the contact area between the bottom of the casting and the water in the cooling box 1, the design of the pad strip 9 allows the bottom of the casting to have space after it is placed on the hollow placement plate 7, which facilitates uniform cooling of the casting.

[0034] Among them, the upper surface of the hollow placement plate 7 has multiple filter holes 8 evenly distributed in an array between every two pads 9.

[0035] In order to facilitate the raising and lowering of the perforated plate 7 inside the cooling box 1, water in the cooling box 1 will drain through the filter holes 8 when the perforated plate 7 is raised and lowered, thereby reducing the resistance of the water in the cooling box 1 to the perforated plate 7 when it is raised and lowered.

[0036] The two mounting strips 17 have grooves 18 on their opposite sides that correspond to the two sides of the hollowed-out placement plate 7. The two sides of the hollowed-out placement plate 7 are slidably connected in the two grooves 18.

[0037] In order to allow the hollow placement plate 7 to slide out and place the casting, the hollow placement plate 7 is slidably connected to the slide groove 18 on both sides, which not only allows the hollow placement plate 7 to slide out, but also supports it when it slides out.

[0038] The top plate 20 has rotating rods 13 at both ends, and each of the two rotating rods 13 has a support plate 12 that rotates through both ends. The four support plates 12 are fixedly connected to the surfaces at both ends of the top plate 20. A motor 16 for driving the rotating rods 13 is fixedly installed on one end of each of the two rotating rods 13 on the side of the support plate 12.

[0039] To facilitate the raising and lowering of the hollow placement plate 7, two motors 16 can be started to drive two rotating rods 13 to rotate, thereby controlling the raising and lowering of the hollow placement plate 7.

[0040] Among them, both ends of the two rotating rods 13 are fixedly connected to the winding reels 14, and multiple winding reels 14 are wound with pull ropes 15. One end of the multiple pull ropes 15 is fixedly connected to both ends of the two mounting strips 17 respectively.

[0041] In order to raise and lower the hollow placement plate 7 by rotating the rotating rod 13, the rotating rod 13 will drive the winding reel 14 on it to rotate together. Since the other end of the pull rope 15 is fixedly connected to the mounting strip 17, the winding reel 14 will wind and unwind the pull rope 15 to control the raising and lowering of the hollow placement plate 7 when it rotates.

[0042] Working principle: Through the design of side plate 2, grid plate 4, ventilation hole 5, fan 6, hollow placement plate 7, pull ring 11, mounting strip 17 and top plate 20, when the heat-treated casting needs to be cooled, coolant is injected into the cooling box 1, the hollow placement plate 7 is first raised to the top of the cooling box 1, and then the hollow placement plate 7 is pulled out by the pull ring 11, so that the casting can be placed on the hollow placement plate 7. Finally, the hollow placement plate 7 is pushed back to its original position and lowered into the cooling box 1 for cooling. The cooperation of side plate 2 and top plate 20 has a protective function. After cooling, the hollow placement plate 7 is raised to the top of the cooling box 1 and the fan 6 is started to work in the ventilation hole 5, so that the moisture on the casting can be dried quickly. The design of grid plate 4 on side plate 2 facilitates ventilation and cooling of the casting when the fan 6 is working, ensuring the safety of the workers and improving the protection of the workers.

[0043] The working process of the cooling device in this embodiment is as follows:

[0044] (I) Preparation Stage

[0045] 1. Installation and debugging

[0046] Fill the cooling tank 1 with an appropriate amount of coolant (such as water or a special cooling medium).

[0047] Check whether the motor 16, fan 6, pull rope 15 and other components are properly connected, and ensure that the slide rail 10 and slide groove 18 are not stuck.

[0048] 2. Operations before placing the casting

[0049] Start the motor 16 to drive the rotating rod 13 to rotate, and the winding reel 14 will wind up the pull rope 15 to lift the installation strip 17 and the hollow placement plate 7 to the top of the cooling box 1.

[0050] Hold the pull ring 11 and pull the hollowed-out placement plate 7 horizontally out of the slide groove 18 of the mounting strip 17 to facilitate the placement of machine tool castings.

[0051] (II) Cooling Stage

[0052] 1. Casting loading

[0053] The heat-treated machine tool casting is placed on the hollowed-out placement plate 7, with the bottom of the casting in contact with the pad strip 9 to ensure that the bottom is suspended and in contact with the coolant through the filter hole 8.

[0054] 2. Reset and Cooling

[0055] Push the hollow placement plate 7 back to its original position along the slide groove 18, turn off the motor 16, and release the pull rope 15 to allow the hollow placement plate 7 to slowly descend into the coolant in the cooling box 1.

[0056] The coolant contacts the casting through the filter hole 8, and the pad 9 supports the casting to increase the cooling area and achieve uniform cooling.

[0057] (III) Air-drying stage

[0058] 1. Remove the casting

[0059] After cooling is complete, start motor 16 again, rewind rope 15, and lift the hollow placement plate 7 above the cooling box 1 to remove it from the coolant.

[0060] 2. Ventilate and air dry

[0061] Start the fan 6 to send air into the cooling box 1 through the ventilation hole 5. The airflow is discharged through the grid plate 4 to quickly dry the moisture on the surface of the casting.

[0062] The side plate 2 and the top plate 20 form a protective structure to prevent coolant from splashing or debris from entering, ensuring the safety of operators.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
