[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an air conditioner housing stamping machine, including a workbench 1 and an arc-shaped top plate 5. The upper surface of the workbench 1 is provided with a lower die base 3, and two arc-shaped grooves 301 are opened on the lower die base 3. A U-shaped bracket 2 is provided on the workbench 1, and an electric hydraulic cylinder 9 is embedded in the U-shaped bracket 2. The output end of the electric hydraulic cylinder 9 is connected to an upper die base 4. The upper die base 4 is located directly above the lower die base 3, which can realize the stamping process of the air conditioner housing.

[0024] Two arc-shaped top plates 5 are provided. A shaft 501 is provided through one end of the arc-shaped top plate 5. Two circular grooves are opened in the arc-shaped groove 301. The shaft 501 is rotatably fitted between the two circular grooves. Bearings are fitted in the circular grooves. The two ends of the gear 502 are respectively fitted with the inner rings of the two bearings, which can facilitate the rotation of the shaft 501 in the arc-shaped groove 301.

[0025] One end of the shaft 501 passes through the circular groove to the outside of the lower mold base 3. A gear 502 is fitted on the outer surface of one end of the shaft 501. Vertical plates 6 are provided on both sides of the lower mold base 3. A rack 601 is fitted on the vertical plate 6. The gear 502 meshes with the rack 601. A pneumatic push rod 602 is provided on the vertical plate 6. The output end of the pneumatic push rod 602 is connected to the bottom end of the rack 601. A limiting groove 603 is provided on the vertical plate 6. One side of the rack 601 is slidably fitted in the limiting groove 603, which can ensure that the rack 601 can slide up and down on the vertical plate 6. A push plate is provided at the bottom end of the rack 601. The output end of the pneumatic push rod 602 is connected to the bottom of the push plate, which can easily push the rack 601 to slide on the vertical plate 6.

[0026] In use, the sheet metal is placed flat on the lower mold base 3, and then the electric hydraulic cylinder 9 is started. The output end of the electric hydraulic cylinder 9 pushes the upper mold base 4 to move down to stamp the sheet metal on the lower mold base 3. After stamping, the output end of the electric hydraulic cylinder 9 controls the upper mold base 4 to move up and reset. Then, the output ends of the two pneumatic push rods 602 on the two vertical plates 6 push the corresponding racks 601 to slide upward in the limiting grooves 603, so that the racks 601 move upward. The racks 601 mesh with the gears 502. As the racks 601 move upward, the gears 502 drive the shaft 501 to rotate, so that the shaft 501 drives one end of the arc-shaped top plate 5 to rotate in the arc-shaped groove 301. This causes the two arc-shaped top plates 5 to separate from the corresponding arc-shaped grooves 301 and rotate 90 degrees on the lower mold base 3, so that the formed air conditioner shell is flipped out from the lower mold base 3 and ejected from the lower mold base 3, thus realizing the removal of the air conditioner shell formed in the lower mold base 3.

[0027] The upper surface of the workbench 1 is provided with an arc-shaped guide plate 7, which can guide the air conditioner housing after stamping to slide down and ensure that the air conditioner housing can enter the collection box 8. One side of the arc-shaped guide plate 7 contacts the lower die base 3. A rectangular through groove 101 is provided on the workbench 1, and the collection box 8 is fitted in the rectangular through groove 101. The side of the arc-shaped guide plate 7 away from the lower die base 3 contacts the top of the collection box 8.

[0028] After the air conditioner housing is flipped and ejected from the lower mold base 3 by the arc-shaped top plate 5, the air conditioner housing falls onto the arc-shaped guide plate 7 near the lower mold base 3. Then, it slides along the arc surface of the arc-shaped guide plate 7 into the collection box 8 on one side of the arc-shaped guide plate 7. The collection box 8 collects the formed air conditioner housing. After collecting a sufficient number of air conditioner housings in the collection box 8, the pull ring on the collection box 8 is pulled. Through the cooperation of the slide bar 801 and the slide groove 102, the collection box 8 slides out of the rectangular through groove 101, and the air conditioner housing stored in the collection box 8 is removed. Then, the collection box 8 is reset, thereby realizing the collection and removal of the air conditioner housing.
