Description

Technical Field

[0001] This utility model relates to the field of cooling technology, specifically to a forging cooling device. Background Technology

[0002] Cooling of forgings has a significant impact on their microstructure, such as grain size. This microstructure directly determines the macroscopic properties of forgings, such as strength, toughness, homogenization, and density. Therefore, choosing a suitable cooling method is of utmost importance.

[0003] In the existing technology, common cooling methods for forgings include air cooling and water cooling. Air cooling usually involves placing the forging in the air and using a blower to accelerate airflow and thus speed up the cooling process. This method is inefficient, slow in cooling, results in low grain size, and poor forging performance. Water cooling usually involves immersing the forging directly in water. This method has a fast cooling speed, but the forging is prone to cracking and has a low yield. Furthermore, uneven cooling can also lead to localized cracking of the forging. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a forging cooling device with high and uniform cooling efficiency, high grain size, and high forging quality.

For example, they can refer to fixed connections, detachable connections, or integrally formed connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections.

[0026] like Figure 1-4 As shown in the figure, an embodiment of a forging cooling device includes a spray cooling chamber 1, a temperature measuring zone 2 and an immersion cooling pool 3 arranged in sequence, and also includes a conveying assembly 4 for conveying the forging from the spray cooling chamber 1 to the immersion cooling pool 3.

[0027] The spray cooling chamber 1 includes an inlet 11 and an outlet 12 arranged opposite to each other. The temperature measuring area 2 and the immersion cooling pool 3 are both arranged on one side of the outlet 12. The spray cooling chamber 1 includes a top wall 13, a bottom wall 14 and two side walls 15. The lower surface of the top wall 13 is provided with a first spray area 131, the inner surface of the side wall 15 is provided with a second spray area 151, and a third spray area 161 is slidably connected between the two side walls 15 and is arranged opposite to the first spray area 131.

[0028] The conveying assembly 4 includes a forged support member 41, which passes through the spray space enclosed by the first spray zone 131, the second spray zone 151 and the third spray zone 161.

[0029] Furthermore, the forging cooling device also includes a base 6, a spray cooling chamber 1, a temperature measuring zone 2, and an immersion cooling pool 3, all of which are located on the base 6.

[0030] The forging first enters the spray cooling chamber 1 for initial cooling via a sequentially arranged spray cooling chamber 1, temperature measuring zone 2, and immersion cooling pool 3. After exiting the outlet 12 of the spray cooling chamber 1, it enters the temperature measuring zone 2 to measure the temperature of the forging. When the temperature is lower than the set temperature value, the forging enters the immersion cooling pool 3 for final and comprehensive cooling. However, when the temperature is higher than the set temperature value, the forging returns to the spray cooling chamber 1 for secondary spray cooling. The set temperature value here is the critical temperature at which the forging will not crack when directly immersed in water cooling, as determined by testing. In this embodiment, spray cooling and immersion cooling are combined to increase the cooling speed of the forging while avoiding surface cracking, effectively improving the grain size and thus the quality of the forging product.

[0031] The spray cooling chamber 1 is designed to atomize water to form water molecules that act on the surface of the forging, ensuring uniform cooling of the forging surface; at the same time, spray cooling is performed before immersion cooling to avoid excessively fast cooling that could cause the forging to crack.

[0032] The device features multi-directional spray zones for more comprehensive and uniform cooling of the forging surface, resulting in excellent cooling performance. Specifically, water is converted into a mist and sprayed onto the forging surface, ensuring more even coverage. Furthermore, the mist is finer than water, allowing it to penetrate the forging surface and reach its interior for effective cooling, thus improving cooling efficiency.

[0033] The forging support member 41 is provided to support the forging to complete the transfer from the spray cooling chamber 1 to the immersion cooling pool 3.

[0034] like Figure 1-4As shown, in another preferred embodiment, the first spray zone 131, the second spray zone 151 and the third spray zone 161 are respectively provided with a first spray head 1311, a second spray head 1511 and a third spray head 1611; the first spray head 1311 and the third spray head 1611 are arranged facing each other; the second spray head 1511 on the two side walls 15 are arranged facing each other.

[0035] The first spray zone 131 and the third spray zone 161 are arranged opposite each other and spray the forgings in the vertical direction to cool them; the second spray zone 151 on both side walls 15 is arranged opposite each other and sprays the forgings in the horizontal direction to cool them; this ensures that the surface of the forgings is sprayed thoroughly and cooled evenly, thereby improving the quality of the forgings.

[0036] Furthermore, each spray zone is equipped with multiple spray heads, which are evenly spaced to ensure uniform spraying of the forgings.

[0037] Furthermore, the angle between the spray surface of the first spray head 1311 and the lower surface of the top wall 13 is 45°, and the spray surface of the third spray head 1611 is arranged facing the spray surface of the first spray head 1311. The 45° angle of the first spray head 1311 allows the spray to act on the top and side of the forging simultaneously; similarly, the angle of the third spray head 1611 allows the spray to act on the bottom and another side of the forging simultaneously; this provides more comprehensive spraying of the forging, improving the cooling effect and the quality of the forging.

[0038] like Figure 1-4 As shown, in another preferred embodiment, the third spray zone 161 includes a water pipe 1612 and a third spray head 1611, the third spray head 1611 being disposed on the outer wall of the water pipe 1612 and communicating with the water pipe 1612.

[0039] Furthermore, an atomizing device is installed inside the water pipe 1612. The water in the water pipe 1612 is processed by the atomizing pump and then sprayed out from the spray head in a mist form.

[0040] like Figure 1-4 As shown, in another preferred embodiment, the side wall 15 is provided with a guide hole 152, and the water pipe 1612 is slidably connected to the side wall 15 through the guide hole 152 and slides up and down along the guide hole 152.

[0041] In this embodiment, the guide hole 152 is a waist hole;

[0042] The length of the guide hole 152 extends vertically, and the height of the third spray zone 161 is adjustable, thereby adjusting the distance between the third spray zone 161 and the forging. Different distances result in different cooling effects of the third spray zone 161 on the forging, thus achieving controllable cooling effect.

[0043] like Figure 1-4As shown, in another preferred embodiment, the conveying assembly 4 further includes a conveying track 42 and a trolley 43; the conveying track 42 is disposed on the top wall 13 and extends above the immersion cooling pool 3; one end of the trolley 43 is slidably connected to the conveying track 42, and the other end is connected to the forging carrier 41.

[0044] The conveying direction and route of the forging are determined by the conveying track 42; the forging is fixed by the cooperation of the traveling crane 43 and the forging carrier 41, and the height of the forging carrier 41 and the forging can be adjusted in the vertical direction by the traveling crane 43, that is, the distance between the forging and the first spray zone 131 and the third spray zone 161 is adjusted, and different distances achieve different cooling effects; the traveling crane 43 cooperates with the conveying track 42 and moves along the conveying track 42 to realize the conveying of the forging.

[0045] Furthermore, a support frame is installed above the immersion cooling pool 3, and the support frame is connected to the conveyor track 42. The support frame ensures the stability of the conveyor track 42.

[0046] like Figure 1-4 As shown, in another preferred embodiment, the temperature measuring zone 2 is provided with an infrared thermometer 21. The infrared thermometer 21 is located between the discharge port 12 and the immersion cooling pool 3 to measure the temperature of the forging after spray cooling. The infrared thermometer 21 is fixed to the lifting rod 22 and the height of the infrared thermometer 21 is adjusted by the lifting rod 22.

[0047] The temperature of the forging is measured by an infrared thermometer 21 to determine the subsequent running direction and cooling method of the forging.

[0048] In this embodiment, the lifting rod includes an inner rod and an outer rod. The outer rod is disposed on the base and sleeved on the inner rod. The outer rod is provided with a waist hole, and the inner rod is provided with a through hole. A locking member is inserted through the waist hole and the through hole to fix the outer rod and the inner rod. The height of the inner rod is adjusted by the movement of the locking member in the waist hole.

[0049] like Figure 1-4 As shown, in another preferred embodiment, the first spray zone 131, the second spray zone 151 and the third spray zone 161 are all connected to the water tank 5.

[0050] Water tank 5 is configured to provide water for spray cooling of forgings.

[0051] Furthermore, the first spray zone 131, the second spray zone 151 and the third spray zone 161 are respectively connected to the water tank 5 through shut-off valves. The shut-off valves can control the first spray zone 131, the second spray zone 151 and the third spray zone 161 to work independently in their respective zones.

[0052] like Figure 1-4 As shown, in another preferred embodiment, the bottom wall 14 is provided with a water storage tank 141.

[0053] The water storage tank 141 collects water from the spray cooling chamber 1.

[0054] The operating steps of this utility model are as follows:

[0055] Step 1: Place the forging on the forging support 41, and the crane 43 lifts the forging support 41 containing the forging; place the third spray zone 161 between the two side walls 15; adjust the height of the forging support 41 and the third spray zone 161;

[0056] Step 2: Start the crane 43 to move along the conveyor track 42 (i.e., from the feed inlet 11 to the discharge outlet 12), and simultaneously start the first spray zone 131, the second spray zone 151 and the third spray zone 161;

[0057] Step 3: The forging moves to temperature measurement zone 2, and the crane 43 stops moving; adjust the height of the lifting rod 22 so that the infrared thermometer 21 measures the temperature of the forging;

[0058] Step 4: Compare the temperature measured in Step 3 with the preset temperature; if the measured temperature is greater than the preset temperature, start the crane 43 to move in the reverse direction (i.e., move from the discharge port 12 to the feed port 11) to perform secondary spray cooling, and then repeat Step 2 to Step 4; if the measured temperature is less than or equal to the preset temperature, start the crane 43 to continue moving forward to the top of the immersion cooling pool 3, and lower the forging carrier 41 into the immersion cooling pool 3 for final cooling.

[0059] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
