Description

Technical Field

[0001] This utility model relates to the field of refrigerator back panel processing technology, specifically a refrigerator back panel grooving device. Background Technology

[0002] The back panel of a refrigerator is an important component of its structure. Located at the rear, it typically covers the main components such as the condenser and compressor. The back panel is generally made of metal (such as steel or aluminum), plastic, or composite materials to provide sufficient strength and durability. It protects the internal electrical and mechanical components from interference and damage from external objects. It blocks dust, dirt, and other external factors from affecting the equipment. The back panel often acts as a radiator for the condenser, helping to dissipate heat generated inside the refrigerator and maintain the system's normal operating temperature. In the design and operation of a refrigerator, the quality and condition of the back panel directly affect the equipment's performance and lifespan.

[0003] When the back panel of a refrigerator is being grooved, the stamping force can easily cause the back panel to stick to the mold, requiring manual removal. Manual removal during equipment operation is time-consuming and potentially dangerous. Conventional stamping dies may cause inconsistent stamping paths when moving vertically, resulting in mismatched groove positions and dimensions for multiple back panels. Therefore, a refrigerator back panel grooving device that automatically ejects the back panel and restricts the stamping die path is designed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a refrigerator back panel pressing device, which has the advantages of automatically ejecting the back panel and restricting the stamping die path. It solves the problem that the stamping force can easily cause the back panel to stick to the die, requiring manual removal. Manual removal during equipment operation is time-consuming and dangerous. Conventional stamping dies may cause inconsistent stamping movement paths when moving vertically, resulting in mismatched pressing positions and sizes of multiple back panels.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goals of automatically ejecting the back panel and limiting the path of the stamping die, this utility model provides the following technical solution: a refrigerator back panel pressing device, including a control cabinet and a support leg installed on the lower side of the control cabinet, and a cabinet door on the front side of the control cabinet. An operating table is fixedly installed on the top of the control cabinet, and a support block is installed on the upper side of the operating table. A lower pressing frame is fixedly installed on the upper end of the support block, and multiple top columns are installed inside the support block. One end of each top column penetrates the interior of the lower pressing frame. A top plate is provided above the operating table, and an upper pressing plate is installed on the lower side of the top plate. A pressing die is fixedly installed on the lower side of the upper pressing plate, and limiting grooves are provided on both sides of the upper pressing plate. The back panel is placed on the upper side of the lower pressure frame, aligning its position with the frame. The upper pressure plate on the lower side of the top plate drives the pressing mold to move vertically, pressing a groove into the back panel of the refrigerator. As the upper pressure plate moves, the limiting groove restricts its vertical movement, ensuring that the pressing position and size of multiple back panels are consistent. When the pressing is complete, the top column moves vertically, pushing the back panel out from the upper side of the lower pressure frame. It can then be directly removed by workers, greatly reducing the probability of danger.

[0008] Preferably, a pneumatic cylinder is installed inside the operating platform, with its lower end located inside the control cabinet. A connecting plate is fixedly installed at the output end of the pneumatic cylinder, and the outer side of the connecting plate is slidably connected to one side of the support block. The top column is fixedly installed on the upper side of the connecting plate. The non-output end of the pneumatic cylinder passes through the inner walls of the operating platform and the control cabinet in sequence and is fixed to the top of the control cabinet. The outer side of the connecting plate is also slidably connected to one side of the support block. The support block can restrict the vertical movement path of the connecting plate. When the pressing groove is completed, the pneumatic cylinder drives the connecting plate to move vertically, causing it to push the top column out of the refrigerator back panel on the upper side of the lower pressing frame, facilitating timely removal.

[0009] Preferably, a hydraulic cylinder is provided inside the top plate, and the output end of the hydraulic cylinder is located on the lower side of the top plate. The upper pressure plate is fixedly installed on the output end of the hydraulic cylinder, and the upper end of the hydraulic cylinder penetrates through the interior of the top plate. The hydraulic cylinder is fixed to the inner wall of the top plate, and its non-output end is located on the upper side of the top plate. The hydraulic cylinder drives the upper pressure plate to move vertically on the lower side of the top plate, which in turn drives the grooving mold to move vertically, thereby performing grooving treatment on the refrigerator back panel on the upper side of the lower pressure frame.

[0010] Preferably, a side support frame is installed between the top plate and the operating table, and the side support frame is installed at both ends of the operating table. The two ends of the side support frame are fixedly connected to the lower side of the top plate and the upper side of the operating table, respectively. The top plate is set on the upper side of the operating table through the side support frame, and the two ends of the side support frame are fixedly installed to the lower side of the top plate and the upper side of the operating table, respectively, by bolts.

[0011] Preferably, a support column is fixedly installed at one end of the lower side of the top plate, and the lower end of the support column is fixedly connected to the upper side of the operating table. The side support frame and the support column are used in conjunction. The support column, used in conjunction with the side support frame, can increase the stability between the top plate and the operating table. Both ends of the support column are also fixedly installed to the lower side of the top plate and the upper side of the operating table respectively by bolts.

[0012] Preferably, sliding blocks are fixedly installed at both ends of the upper pressure plate, and the sliding blocks are slidably connected to the inner wall of the limiting groove. The two ends of the limiting groove are fixedly connected to the lower side of the top plate and the upper side of the operating platform, respectively, and the limiting groove is located between two adjacent support piers. The two ends of the upper pressure plate are connected to the inner wall of the limiting groove via sliding blocks. When the upper pressure plate moves vertically, it drives the sliding blocks to move vertically along the inner wall of the limiting groove, which indirectly improves the stability of the upper pressure plate during movement. Furthermore, the limiting groove can be used in conjunction with side support frames and support columns to enhance the stability between the top plate and the operating platform.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a refrigerator back panel pressing device, which has the following beneficial effects: This refrigerator back panel pressing device places the back panel on the upper side of the lower pressing frame, and the upper pressing plate on the lower side of the top plate drives the pressing mold to move vertically, so as to press the refrigerator back panel. When the upper pressing plate moves, the vertical movement path of the upper pressing plate is restricted by the limiting groove. When the pressing is completed, the top column moves vertically to push the refrigerator back panel out from the upper side of the lower pressing frame, thereby achieving the effects of automatically pushing out the back panel and restricting the path of the pressing mold.
