Description

Technical Field

[0001] This utility model relates to the field of mold cooling technology, and more specifically, to a rapid cooling tooling for hot forging molds. Background Technology

[0002] Forging processes performed above the recrystallization temperature of a metal are called hot forging, also known as hot die forging. During forging, the deformed metal flows violently, and the contact time between the forging and the die is relatively long. Therefore, the die material is required to have high thermal stability, high-temperature strength and hardness, impact toughness, thermal fatigue resistance, and wear resistance, and to be easy to machine. Forging dies with lighter workloads can be made of low-alloy steel. During the forging process, the die temperature rises due to prolonged contact with the hot billet, requiring cooling to ensure the overall performance of the die.

[0003] A search revealed Chinese patent utility model number 202023131836.5, which discloses a rapid cooling fixture for hot forging molds. The fixture includes a liquid storage tank and an inlet pipe connected to the top of one side of the tank. A valve is fixedly installed on the outer edge of the inlet pipe away from the tank. Support plates are welded to the top of both sides of the tank, and water pumps are fixedly installed at the bottom of both sides. Two ear plates are symmetrically arranged on the opposite sides of the two support plates, and a circular groove for fixing bearings is centrally formed on the facing surfaces of the ear plates. Lead screws are movably connected to the two bearings, and the top of the lead screws passes through the bearings and is fixedly connected to a motor installed on the top of the ear plates. Rectangular grooves for sliding rectangular sliders are centrally formed on the opposite sides of the support plates. This rapid cooling fixture for hot forging molds saves time and labor, improves production efficiency, eliminates the need to be near the heated mold, ensures high safety, and is easy for operators to use. However, the aforementioned patents have the following shortcomings: the screens are easily clogged by debris and powder generated during workpiece forging, and the bottom die and punch cannot be cooled simultaneously, resulting in a slow cooling rate. Therefore, this utility model proposes a new solution. Utility Model Content

The filter assembly penetrates the bottom of the liquid collection box 2 and the top of the liquid storage tank 1. The filter assembly includes a hemispherical screen 7 and a drive mechanism. The output end of the drive mechanism is connected to a cleaning mechanism for cleaning the screen 7. By setting up the screen 7, drive mechanism, and cleaning mechanism, the cleaning mechanism can be driven to rotate during use, thereby continuously cleaning the debris and dust on the screen 7, preventing the screen 7 from being blocked by debris and powder generated during workpiece forging, maintaining the good filtration effect of the screen 7, and ensuring that the coolant can flow smoothly through the screen 7. The liquid is fed into the interior of the storage tank 1. A first bidirectional moving mechanism 5 and a second bidirectional moving mechanism 6 are respectively installed on the two side walls of the storage tank 1. A first slider 8 and a second slider 9 are installed on the first bidirectional moving mechanism 5 and the second bidirectional moving mechanism 6. A nozzle 11 is installed on the first slider 8 and the second slider 9. A conveying mechanism 4 is installed on the front of the storage tank 1. The output end of the conveying mechanism 4 is provided with multiple hoses for connecting the nozzles 11. By setting the first bidirectional moving mechanism 5, the second bidirectional moving mechanism 6, the first slider 8, the second slider 9 and the nozzles 11, the first slider 8 and the second slider 9 can drive the nozzles 11 installed on them to move simultaneously during use, so as to spray and cool the bottom mold and the punch on the first mounting base 3 at the same time, improve the overall cooling speed and further accelerate the production efficiency.

[0027] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the conveying mechanism 4 further includes a base plate 401, a conveying pump 402 mounted on the top of the base plate 401, the input of the conveying pump 402 being inserted into the interior of the liquid storage tank 1, and a T-shaped connector 403 for connecting a hose being mounted on the output end of the conveying pump 402. It should be noted that the hose is conveyed to the nozzle 11, and then the nozzle 11 sprays and cools the bottom mold and the punch.

[0028] like Figure 1 and Figure 3As shown, in a preferred embodiment, based on the above method, the driving mechanism further includes a second mounting base 17, a screen 7 is mounted on the top of the second mounting base 17, a bracket 18 is fixedly mounted on the inner side of the second mounting base 17, a connecting shaft 19 with its top end penetrating the screen 7 is rotatably mounted at the center of the bracket 18, an impeller 23 located below the bracket 18 is connected to the bottom end of the connecting shaft 19, and through holes 24 that cooperate with the second mounting base 17 are opened on both the liquid collection box 2 and the liquid storage tank 1.

It should be noted that the second mounting base 17 is detachably installed on the inside of the liquid collection box 2 by bolts. The second mounting base 17 facilitates the installation of the bracket 18 and the screen 7. During use, the coolant flowing into the liquid storage tank 1 through the screen 7 can drive the impeller 23 to rotate, thereby driving the mounting rod 20 to rotate through the connecting shaft 19, so that the cleaning brush 22 on the inside of the mounting rod 20 can clean the debris on the outside of the screen 7.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, a flow channel 14 is further provided on the top of the first mounting base 3. Connecting pipes 15 and discharge pipes 16, which communicate with the interior of the flow channel 14, are installed on both side walls of the first mounting base 3.

It should be noted that in use, the motor 10 can drive the bidirectional lead screw 12 to rotate in both forward and reverse cycles, thereby driving the first slider 8 and the second slider 9 to move in opposite directions, so that the nozzles 11 mounted on them can perform cyclic spray cooling on the bottom mold and the punch.

[0031] Specifically, the working principle of this rapid cooling fixture for hot forging molds is as follows: During use, the bottom mold is installed on the first mounting base 3. When cooling is required, the conveying mechanism 4 is activated to deliver coolant to the nozzle 11. Then, the first bidirectional moving mechanism 5 and the second bidirectional moving mechanism 6 drive the first slider 8 and the second slider 9 to reciprocate. The coolant is sprayed onto the bottom mold and the punch through the nozzles 11 installed on the first slider 8 and the second slider 9. While spraying and cooling, the conveying mechanism 4 can deliver the coolant to the flow channel 14 at the top of the first mounting base 3 through the connecting pipe 15, cooling the bottom mold from the bottom, thereby accelerating the cooling speed of the bottom mold. When filtering the cooling liquid, the drive mechanism can drive the cleaning mechanism to rotate, thereby continuously cleaning the debris and dust on the screen 7, preventing the screen 7 from being blocked by debris and powder generated during workpiece forging, and maintaining the good filtration effect of the screen 7.
