Description

Technical Field

[0001] This utility model relates to an auxiliary cooling device for iron graphite cast iron parts of automotive brake drums, belonging to the technical field of auxiliary cooling devices. Background Technology

[0002] When machining automotive brake drum ball graphite cast iron parts, it is necessary to cool the cast iron parts to facilitate the work of the staff and make it easier for them to continue processing.

[0003] Chinese Patent Publication No. (CN 220567578 U) discloses a cooling device for parts processing, belonging to the field of parts processing technology. It includes a support frame with a perforated conveyor belt circulating within it for transporting parts to be cooled. A water storage tank is located on the lower side of the perforated conveyor belt, storing clean water. A first transition tank, a second transition tank, and a third transition tank are sequentially fixedly connected to the upper side of the support frame. A water spray pipe is fixedly connected to the first transition tank. A circulation mechanism is installed on the support frame, which circulates clean water into the water spray pipe to spray and cool the parts. Air-cooling mechanisms are installed on the second and third transition tanks, using airflow to cool the parts and remove surface water droplets. Through three cooling cycles, the cooling effect is greatly enhanced, effectively cooling the parts and removing surface water droplets, reducing the need for drying.

[0004] However, the production of existing cast iron parts generates a large amount of high temperature. In order to facilitate subsequent processing by workers, the cast iron parts need to be cooled down. However, the existing cooling method is to cool down by immersion, which has low cooling efficiency. It is also inconvenient for workers to handle when the parts are picked up, resulting in low work efficiency.

The cooling box 1 is equipped with a cooling mechanism 2 inside. The cooling mechanism 2 includes an extraction box 201, a connecting pipe 202, and an air outlet 203. The bottom of the extraction box 201 is fixedly connected to the top of the cooling box 1, and the bottom of the extraction box 201 extends into the interior of the cooling box 1. The inner side of the connecting pipe 202 is connected to the outer side of the cooling box 1, and the outer side of the air outlet 203 is connected to the inner side of the connecting pipe 202. The front side of the cooling box 1 is movably connected to a movable door 3 via a hinge. An observation window 4 is opened on the front side of the movable door 3. A limiting block 5 is fixedly connected to the inner wall of the cooling box 1. The limiting block 5 is sleeved on the surface of the connecting pipe 202. A rotary motor 6 is fixedly connected inside the cooling box 1. A placement plate 7 is fixedly connected to the output end of the rotary motor 6. A placement frame 8 is movably connected to the top of the placement plate 7. A ventilation groove 9 is opened on the surface of the placement frame 8.

[0030] When cooling the casting, the cooling mechanism 2 draws outside air into the air extraction box 201, and the cold air is blown out from the air outlet 203 through the connecting pipe 202 to cool the casting. The movable door 3 and the observation window 4 are provided to facilitate the staff to observe the cooling situation.

[0031] Example 2

[0032] like Figure 3 and Figure 4 As shown, in one embodiment, a positioning block 10 is fixedly connected to the front side of the placement plate 7. A cavity 11 is formed inside the positioning block 10, and a positioning mechanism 12 is provided inside the cavity 11. The positioning mechanism 12 includes a pull rod 1201, a fixing post 1202, a rotating rod 1203, a connecting rod 1204, and a compression spring 1205. The right side of the pull rod 1201 extends through the cavity 11 to the right side of the positioning block 10, and the left side of the pull rod 1201 extends into the cavity 11. The rear side of the fixing post 1202 is fixedly connected to... The front side of the pull rod 1201 and the front side of the fixing post 1202 extend to the front side of the rotating rod 1203. The rotating rod 1203 is movably connected to the inside of the cavity 11 via a rotating shaft. The inner side of the rotating rod 1203 contacts the outer side of the connecting rod 1204. The outer side of the compression spring 1205 is fixedly connected to the inner side of the connecting rod 1204.

[0034] In operation, the uncooled casting is first placed inside the placement frame 8, and the placement frame 8 is placed on top of the placement plate 7. The pull rod 1201 is then pulled downwards, causing the fixed column 1202 to move downwards. The fixed column 1202 then causes the rotating rod 1203 to move downwards. The rotating rod 1203 rotates around its axis, and during rotation, the surface of the rotating rod 1203 presses against the inner side of the connecting rod 1204, causing the connecting rod 1204 to move inwards simultaneously. At this point, the placement frame 8 can be installed. Release the compression spring 1205 so that the connecting rod 1204 can be inserted into the fixed groove 13. At this moment, start the suction box 201 to draw external air into the suction box 201. The air is sprayed out from the air outlet 203 through the connecting pipe 202 to cool the casting. During cooling, start the rotary motor 6. The rotary motor 6 drives the placement plate 7 to rotate, continuously rotating the placement frame 8 and gradually cooling the inside of the placement frame 8.
