The casting is moved by a first conveyor roller, and after the first cooling and cleaning are completed, the casting on the first conveyor roller flows into the second conveyor roller through the gap between the first hood and the second hood, a sealed chamber is formed inside the second hood through the second door curtain, and air is blown into the second hood by a cold air blower to complete secondary cooling of the casting, thereby accelerating the cooling speed of the casting. After the casting is conveyed to the second conveyor roller by the first conveyor roller, the cold air blower is turned on, and the cold air in the cold air blower reaches the inside of the second hood through the air outlet pipe through the connecting pipe, thereby completing secondary cooling of the casting on the second conveyor roller.

In actual operation, the contact area between the bottom of the casting and the conveyor rollers is large, and the cooling wind is difficult to act on the bottom of the casting. Although the cooling speed of the casting is greatly improved, it still has certain limitations. Utility Model Content

[0025] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0026] Embodiment 1:

[0027] This embodiment introduces a specific structure of a rapid cooling device for casting processing. Figure 1-Figure 3 As shown, the rapid cooling device includes a transfer mechanism, which includes a carrier frame 3 for carrying the casting to be cooled and two vertical frames 4 symmetrically arranged on the left and right. The tops of the two vertical frames 4 are assembled and connected with a first horizontal bar 6, and the bottoms of the two vertical frames 4 are assembled and connected with a second horizontal bar 11. Two hydraulic cylinders 10 are arranged on one side of the two second horizontal bars 11.

[0028] Among them, the inner sides of the four corners of the carrier frame 3 are welded with angle plates 5. By hingedly connecting one end of the hydraulic cylinder 10 with the bottom of the angle plate 5, the other end of the hydraulic cylinder 10 is hingedly connected with one end of the second horizontal bar 11, so that one end of the four hydraulic cylinders 10 is supported at the bottom of the four corners of the carrier frame 3 respectively. When the four hydraulic cylinders 10 are working, the carrier frame 3 can be pushed to move toward the top, thereby driving the casting to be cooled mounted on the top of the carrier frame 3 to rise, which is beneficial to increase the exposed area of ​​the bottom of the casting to be cooled, and improve the cooling efficiency of the casting by the cold air blown by the cold air blower in the prior art;

[0029] At the same time, by adopting the articulated mode at both ends of the hydraulic cylinder 10, when the supporting frame 3 is controlled to move up and down between the two vertical frames 4, there will be no interference between the supporting frame 3 and the vertical frames 4, thereby ensuring that the supporting frame 3 moves up and down smoothly;

[0030] Secondly, in order to ensure that the support frame 3 can move vertically, Figure 2 and Figure 3 As shown, the bottoms of both ends of the carrier 3 are processed and welded with two limiting long rods 12, and by making the two limiting long rods 12 on one side of the carrier 3 slidably connected to the first horizontal bar 6 and the second horizontal bar 11 on the same side, a fixed track can be provided for the carrier 3 during the up and down movement;

[0031] Furthermore, the bottoms of both sides of the supporting frame 3 are respectively overlapped on the tops of the two upright frames 4. By making one end of the limiting long rod 12 located inside the second horizontal bar 11, when the two upright frames 4 move as a whole, the upright frame 4 will not affect the movement of the supporting frame 3 because one end of the limiting long rod 12 protrudes from the bottom of the upright frame 4.

[0032] By adopting the above technical solution:

[0033] The above-mentioned design sets the supporting frame 3 between the tops of the two vertical frames 4, so that the limiting long rods 12 welded at the two ends of the supporting frame 3 slide inside the first horizontal bar 6 and the second horizontal bar 11 between the two vertical frames 4. When the hydraulic cylinder 10 set at the four corners of the bottom of the supporting frame 3 and hinged to the upper corner plate 5 of the supporting frame 3 at one end works, it pushes the casting to be cooled mounted on the top of the supporting frame 3 to rise, which is beneficial to increase the exposed area of ​​the bottom of the casting to be cooled and improve the effect of the casting being cooled by cold air.

[0034] Embodiment 2:

[0035] Based on Example 1, this example introduces the specific structure of the stand 4. The tops of both ends of the two stands 4 are processed with lap plates 2, one side of the bottom of the lap plate 2 is assembled and connected with a drive motor 8, one end of the rotating shaft of the drive motor 8 is assembled and connected with a roller 9, and the bottoms of the two stands 4 are provided with the same supporting base frame 1, and the tops of both sides of the supporting base frame 1 are processed with positioning ribs 7;

[0036] The lap plate 2 is arranged in an L-shape so that the top surface of the lap plate 2 is flush with the top surface of the carrier 3. When the casting to be cooled is placed on the top of the carrier 3, the two vertical frames 4 can jointly support the casting to be cooled, thereby improving the stability of the casting movement.

[0037] At the same time, by locating the roller 9 and the driving motor 8 on both sides of the bottom of the lap plate 2 respectively, the roller 9 at the same end of the two uprights 4 is rollingly connected to the top of the same positioning rib 7. When the driving motor 8 controls the rotation of the roller 9, the roller 9 can be supported on the top of the positioning rib 7, so that the two uprights 4 can drive the supporting frame 3 to be movably connected to the inner side of the supporting base frame 1, thereby controlling the casting to be cooled mounted on the top of the supporting frame 3 to move into the hood in the prior art and move out from the inside of the hood.

[0038] By adopting the above technical solution:

[0039] The above-mentioned design is achieved by welding a driving motor 8 on one side of the bottom at the top ends of the two vertical frames 4, and a lap plate 2 is provided on the other side which is transmission-connected to the driving motor 8. When the roller 9 is mounted on the top of the positioning rib 7 and the driving motor 8 is working, the driving motor 8 controls the roller 9 to rotate. The roller 9 uses the friction between the roller 9 and the positioning rib 7 to make the lap plate 2 drive the vertical frame 4 to move on the inner side of the supporting base frame 1, thereby driving the bearing frame 3 between the two vertical frames 4 to move, which is beneficial to control the casting to be cooled mounted on the top of the bearing frame 3 to move into the hood in the prior art and move out of the hood.

[0040] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
