Description

Technical Field

[0001] The utility model relates to the technical field of forging production, in particular to a rapid cooling device for aluminum alloy pin forgings. Background Art

[0002] Aluminum alloy pin forging is a pin made of aluminum alloy material, which is processed by forging process. Forging is a metal hot working process, which forms the metal material into the desired shape and size in a plastic state by hammering or pressure.

[0003] A Chinese utility model with authorization announcement number CN213729167U discloses a rapid cooling device for automobile forging processing. When in use, the device controls the operation of an air pump to blow air through the vents connected to the air guide grooves, thereby quickly drying water stains on the surface of the forging. However, in actual use, when the forging is being dried, its lower end face contacts with a support plate, and during the drying process, the cooling airflow is prevented from reaching this area, resulting in this part of the forging being unable to be effectively cooled, resulting in uneven drying. Therefore, it is necessary to redesign the rapid cooling device for aluminum alloy pin forgings to address the above-mentioned problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a rapid cooling device for aluminum alloy pin forgings.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rapid cooling device for aluminum alloy pin forgings comprises a cooling box, the upper end of which is open, a slide plate is slidably connected inside the cooling box, a plurality of through holes are penetrated through the outer wall of the slide plate, two groups of electric telescopic rods are rotatably connected to the inner wall of the cooling box, the ends of the two groups of electric telescopic rods are fixedly connected to clamping plates, two groups of side plates are fixedly connected to the upper end surface of the cooling box, a reciprocating screw is rotatably connected between the two groups of side plates, the reciprocating screw is connected to a jet plate through a connecting mechanism, the jet plate is slidably connected to the inside of the cooling box, and a connecting pipe is installed on the outer wall of the jet plate.

[0007] Preferably, the connecting mechanism comprises a screw sleeve threadedly connected to the threaded section of the reciprocating screw, and the jet plate is fixedly connected to the lower end of the screw sleeve.

[0008] Preferably, a limit rod is fixedly connected between the two groups of side plates, and the lead screw sleeve is slidably connected to the outer wall of the limit rod.

[0009] Preferably, the cooling box and a group of side panels and side walls thereof are rotatably connected to a transmission wheel 1 and a transmission wheel 2 respectively, and the transmission wheel 1 is connected to the transmission wheel 2 through a transmission belt.

[0010] Preferably, the transmission wheel 1 is coaxially fixedly connected to the adjacent electric telescopic rod, and the transmission wheel 2 is coaxially fixedly connected to the reciprocating screw.

[0011] Preferably, a servo motor is fixedly connected to the outer wall of one group of the side panels, and the end of the output shaft of the servo motor is coaxially fixedly connected to the reciprocating screw.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model drives the jet plate to slide back and forth inside the cooling box to spray the air flow evenly to the forgings. With the rotation of the electric telescopic rod, the clamped forgings can be driven to rotate. While drying by themselves, the forgings can be dried in all directions with the sliding jet plate. Not only can the water stains on the surface of the forgings be dried quickly, but also the lower end face of the forgings can be prevented from contacting with the support plate, preventing the cooling air flow from reaching this part of the forging, resulting in the inability to effectively cool this part of the forging, thereby causing the problem of uneven drying.

[0014] 2. The utility model realizes rapid cooling of the aluminum alloy pin forging by injecting cooling water into the cooling box. At the same time, through the design of the electric telescopic rod and the clamping plate, the forging can be stably clamped during the cooling process, avoiding the movement or slipping of the forging during the cooling process, thereby improving the cooling efficiency and safety.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3A rapid cooling device for aluminum alloy pin forgings comprises a cooling box 1, the upper end of the cooling box 1 is open, a slide plate 2 is slidably connected to the cooling box 1, and a plurality of through holes are provided on the outer wall of the slide plate 2. Two sets of electric telescopic rods 9 are rotatably connected to the inner wall of the cooling box 1, and the ends of the two sets of electric telescopic rods 9 are fixedly connected to a clamping plate 10, and two sets of side plates 3 are fixedly connected to the upper end surface of the cooling box 1, and a reciprocating screw 7 is rotatably connected between the two sets of side plates 3. The reciprocating screw 7 is connected to a jet plate 12 through a connecting mechanism, and the jet plate 12 is slidably connected to the inside of the cooling box 1, and the connecting mechanism comprises a screw sleeve 11 threadedly connected to the threaded section of the reciprocating screw 7, and the jet plate 12 is fixedly connected to the lower end of the screw sleeve 11, and a connecting pipe 13 is installed on the outer wall of the jet plate 12.

[0021] With the help of the extension of the telescopic ends of the two sets of electric telescopic rods 9, the clamping plate 10 is driven to contact the outer wall of the aluminum alloy pin shaft forging until it fits with the outer wall to achieve the purpose of clamping it. When air-drying, the rotation of the electric telescopic rod 9 can be used in conjunction with the sliding jet plate 12 to air-dry it in all directions, and the jet plate 12 is connected to an external air pump through a connecting pipe 13.

[0022] A limit rod 8 is fixedly connected between the two groups of side panels 3, and a screw sleeve 11 is slidably connected to the outer wall of the limit rod 8. The cooling box 1 and the side walls of one group of side panels 3 are respectively rotatably connected with a transmission wheel 1 4 and a transmission wheel 2 5. The transmission wheel 1 4 is connected to the transmission wheel 2 5 through a transmission belt 6. The transmission wheel 1 4 is coaxially fixedly connected to the adjacent electric telescopic rod 9, and the transmission wheel 2 5 is coaxially fixedly connected to the reciprocating screw 7. A servo motor 14 is fixedly connected to the outer wall of one group of side panels 3, and the end of the output shaft of the servo motor 14 is coaxially fixedly connected to the reciprocating screw 7. It should be noted that the forging can be clamped and fixed when it is cooled, and the electric telescopic rod 9 does not rotate at this time.

[0023] In the utility model, the specific function of the device is as follows: first, the aluminum alloy pin shaft forging is placed in the cooling box 1, and cooling water is injected into the cooling box 1 to achieve the purpose of rapid cooling. After the cooling is completed, the clamping plate 10 is driven to contact the outer wall of the aluminum alloy pin shaft forging by extending the two sets of electric telescopic rods 9 until it fits with the outer wall to achieve clamping. Then, the servo motor 14 is started, and its output shaft drives the reciprocating screw 7 to rotate, and then drives the jet plate 12 to slide back and forth inside the cooling box 1. The connecting pipe 13 on the outer wall of the jet plate 12 is connected to the external air pump, so that the air flow can be evenly sprayed to the forging.

[0024] At the same time, the transmission wheel 1 4 and the transmission wheel 2 5 are arranged in cooperation to drive the electric telescopic rod 9 to rotate, and synchronously drive the clamped forging to rotate, and at the same time of self-drying, cooperate with the sliding air jet plate 12 to achieve all-round air drying of the forging. In this way, not only can the water stains on the surface of the forging be quickly dried, but also the problem of uneven air drying can be avoided because the lower end surface of the forging is in contact with the support plate, preventing the cooling air flow from reaching this part of the forging, resulting in the inability to effectively cool this part of the forging.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
