Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance manufacturing technology, specifically to a shell stamping device for refrigerator manufacturing. Background Technology
[0002] Refrigerator manufacturing refers to the process of transforming raw materials into refrigerators through a series of manufacturing processes. These mainly include shell forming, insulation layer filling, refrigeration system assembly, and electrical system installation. Automated production lines are used to ensure product quality, improve production efficiency, and meet market demands.
[0003] Stamping is suitable for mass production, enabling the rapid and continuous production of large quantities of identical or similar products, thus improving production efficiency. Therefore, it is necessary to use a refrigerator shell stamping device. However, traditional refrigerator shell stamping devices have a relatively simple design, making it inconvenient to replace stamping dies and to limit the movement of the pressure plate. If die replacement is inconvenient, it will lead to extended production line downtime, thereby reducing overall production efficiency. Inconvenient die replacement means that more time and manpower are needed to complete the die replacement work, which will increase labor costs. If the movement of the pressure plate is not effectively controlled, it may collide with the die or other parts of the stamping device, causing die damage or equipment failure. Utility Model Content
[0004] The purpose of this invention is to provide a shell stamping device for refrigerator production, so as to solve the problems mentioned in the background art.

A connecting block is rotatably connected to one end of the connecting rod. A sliding rod is slidably connected to the inner wall of the connecting block.
[0008] A replacement mechanism is provided on one side of the stamping die to facilitate disassembly and replacement of the stamping die. The replacement mechanism includes a sleeve fixed to the inner wall of the stamping die, a slide tube slidably connected to the inner wall of the sleeve, a snap-fit block snapping onto the outer side of the slide tube, a slider slidably connected to the inner wall of the snap-fit block, and the top of the slider being fixedly connected to the inner wall of the frame.

The mounting column 11 is then reset to achieve a protective effect. At this time, the cylinder 8 is activated. The cylinder 8 drives the pressure plate 31 to move, thereby rolling the metal sheet. At the same time, when the pressure plate 31 moves, it is connected by the connecting plate 32, the connecting rod 33, and the connecting block 34. The connecting block 34 slides outside the slide rod 35, thereby limiting the movement of the pressure plate 31 and preventing it from tilting. When it is necessary to replace the stamping die of the stamping die 2, the slider 44 cooperates to lift the locking block 43 upward. After lifting, the slide tube 42 is reset, thereby disassembling the stamping die 2.
