Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerator production, and particularly relates to a device for expanding the head and discharging the refrigerator condenser tube. Background Art

[0002] During the production of refrigerators, in order to connect multiple condenser tubes, it is necessary to expand the aperture at one end of the condenser tube and reduce the aperture at the other end. Currently, for expanding the aperture, some are manual hole expansion, that is, relying on manual labor to insert the condenser tube into the punching column for hole expansion, and some are automatic hole expansion after placing the condenser tube in the head expansion device. For example, a condenser tube head expansion device disclosed in the utility model patent with the publication number CN215697488U can complete the hole expansion at one end of the condenser tube by clamping the condenser tube and then automatically pushing and sleeving it onto the inner extension column. However, after the hole expansion is completed by this device, it is still necessary to manually remove the condenser tube, which affects the processing efficiency and it is necessary to make improvements. Summary of the Utility Model

Detailed implementation manners

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] An embodiment of the present application provides a device for discharging the expanded heads of refrigerator condenser pipes, as Figures 1 - 3 shown, including a lower pressing plate 1, an upper pressing plate 4, a fixing plate 5, a third pushing mechanism, etc.

[0023] Specifically, the lower pressing plate 1 is rotatably connected between a pair of vertical plates 101. The pair of vertical plates 101 are fixed on a slider 102. The slider 102 is slidably connected to a slide rail 2. The length direction of the slide rail 2 is perpendicular to the length direction of the lower pressing plate 1. A plurality of lower accommodating grooves 103 are formed at the top of the lower pressing plate 1 for accommodating the condenser pipes. The length direction of the lower accommodating grooves 103 is parallel to the length direction of the slide rail 2. One side of the lower pressing plate 1 is hinged to the telescopic end of a first pushing mechanism 3. The fixed end of the first pushing mechanism 3 is hinged to the lower pressing plate 1. The upper pressing plate 4 is arranged above the lower pressing plate 1. A plurality of upper accommodating grooves 401 corresponding to the lower accommodating grooves 103 are formed at the bottom of the upper pressing plate 4. The upper pressing plate 4 is connected to the telescopic end of a second pushing mechanism 402. The second pushing mechanism 402 is fixed above the lower pressing plate 1 through a U - shaped frame 403. The telescopic direction of the telescopic end of the second pushing mechanism 402 is the vertical direction. The fixing plate 5 is arranged at intervals on one side of the lower pressing plate 1. A plurality of stamping columns 501 corresponding to the lower accommodating grooves 103 are arranged along the length direction on the side of the fixing plate 5 facing the lower pressing plate 1 for expanding the heads of the condenser pipes. The third pushing mechanism is connected to the slider 102 for driving the slider 102 to move along the length direction of the slide rail 2.

[0024] During actual use, multiple condenser tubes are respectively placed into multiple lower accommodating grooves 103. Then, the second pushing mechanism 402 is controlled to drive the upper pressing plate 4 to move downward, clamping the condenser tube between the upper accommodating groove 401 and the lower accommodating groove 103. Specifically, rubber sheets can be provided in both the upper accommodating groove 401 and the lower accommodating groove 103 to increase the friction force on the condenser tube. Then, the third pushing mechanism is controlled to drive the slider 102 to move towards the fixed plate 5, so that the end of the condenser tube is sleeved on the stamping post 501, and the head expansion can be completed. Then, the third pushing mechanism is controlled to drive the slider 102 to retract, the second pushing mechanism 402 is controlled to drive the upper pressing plate 4 to retract, and the telescopic end of the first pushing mechanism 3 is controlled to push out, so that the lower pressing plate 1 rotates upward, and the condenser tube in the lower accommodating groove 103 can be poured out of the lower pressing plate 1 to complete the unloading.

[0025] Specifically, refer to Figure 1 , a collecting frame 9 is provided at one end of the slide rail 2 away from the fixed plate 5, which is used to collect the condenser tubes poured out of the lower accommodating groove 103 to prevent the condenser tubes poured out of the lower accommodating groove 103 from scattering everywhere. Specifically, refer to Figure 3 , a support block 1022 is provided on the slider 102, and the support block 1022 is located below the bottom of the lower pressing plate 1 on the side facing the fixed plate 5. When the lower pressing plate 1 is parallel to the slide rail 2, the bottom of the lower pressing plate 1 abuts against the support block 1022, avoiding relying only on the telescopic end of the first pushing mechanism 3 to support the lower pressing plate 1 and improving the stability of the device.

[0026] Specifically, refer to Figure 2 , Figure 3 , the third pushing mechanism includes a screw 6 and a driving motor 601. A threaded hole 1021 is formed in the slider 102 through which the screw 6 passes along the length direction of the slide rail 2. The screw 6 is connected to the threaded hole 1021, and the output shaft of the driving motor 601 is connected to one end of the screw 6. More specifically, the driving motor 601 can be fixed on the side of the fixed plate 5 away from the lower pressing plate 1, so that the screw 6 passes through the fixed plate 5 and is connected to the output shaft of the driving motor 601. Compared with directly using a cylinder or an oil cylinder as the pushing mechanism, the overall length of the device can be reduced, and the floor area of the device can be reduced.

[0027] Preferably, refer to Figure 1 , Figure 3, on one side of the upper pressing plate 4 facing the fixing plate 5, an L-shaped baffle 7 is provided at intervals. The length direction of the L-shaped baffle 7 is parallel to the length direction of the lower pressing plate 1. The vertical section 702 of the L-shaped baffle 7 faces downward, and the horizontal section 701 of the L-shaped baffle 7 faces the upper pressing plate 4. The top of the horizontal section 701 of the L-shaped baffle 7 is connected to the telescopic end of a fourth pushing mechanism 8. The telescopic direction of the fourth pushing mechanism 8 is the vertical direction. When the upper pressing plate 4 presses the condenser tube placed in the lower accommodating groove 103 and the telescopic end of the fourth pushing mechanism 8 is pushed out, the vertical section 702 of the L-shaped baffle 7 covers all the upper accommodating grooves 401 and the lower accommodating groove 103. Before placing the condenser tube into the lower accommodating groove 103, the telescopic end of the fourth pushing mechanism 8 can be controlled to be pushed out first, so that the vertical section 702 of the L-shaped baffle 7 is aligned with the lower accommodating groove 103. After placing the condenser tube into the lower accommodating groove 103, the condenser tube is pushed toward the vertical section 702 of the L-shaped baffle 7. When the condenser tube abuts against the vertical section 702 of the L-shaped baffle 7, the ends of the condenser tubes can be aligned, avoiding the situation that the ends of multiple condenser tubes are not aligned during subsequent reaming, resulting in inconsistent reaming speeds. Moreover, the horizontal section 701 of the L-shaped baffle 7 can block the upward rotation of the condenser tube, preventing the end of the condenser tube that needs to be reamed after being placed in the lower accommodating groove 103 from rotating upward and causing the condenser tube to slide out of the lower pressing plate 1.

[0028] The above are only some embodiments listed in this application and do not limit this application.
