Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator component processing, in particular to a refrigerator door panel bending and forming tool. Background Art

[0002] Freezers, also called freezers, are devices that preserve food and other items at low temperatures. They are divided into household and commercial types. Commercial freezers are used in restaurants, water bars, food processing, and supermarkets. The freezer door panels mainly play a sealing role. In the production process of freezers, bending equipment is needed to bend the freezer door panels.

[0003] For example, a freezer door panel bending and forming tool with authorization announcement number "CN220049552U" drives the rotating rod to rotate, and the threaded sleeve is driven to rotate under the action of the connecting mechanism, so that the threaded rod extends outward and presses on the plate through the pressure plate. When the rotating rod continues to rotate, the pulling mechanism is used to control the bending plate to flip upward to bend one end of the plate. The plate is pressed and fixed by lowering the pressure plate to prevent the plate from shifting during the bending process and affecting the bending effect. The plate is automatically pressed and fixed, which saves time and effort and improves processing efficiency. However, the bending position of the freezer door panel bending and forming tooling is fixed, and the bending position needs to be adjusted manually. The manual operation increases the labor force. At the same time, when the freezer door panel bending and forming tooling is bending the freezer door panel, it is necessary to first limit the position of the freezer door panel. When the freezer door panel is bent, the freezer door panel will move. When the freezer door panel of the device is bent after being limited, the freezer door panel cannot be moved, which affects the bending work of the freezer door panel. Utility Model Content
