Flexible bending die with wheel preventing deformation

Abstract

The invention discloses a flexible bending die with a wheel preventing deformation and belongs to the technical field of metal bending dies. The flexible bending die solves the problems that when an existing outer refrigerator plate is in bent production, a condensing pipe is liable to be bent, shrunken and deformed. The flexible bending die with the wheel preventing deformation comprises an upper die and a lower die. The lower die comprises a lower die base. A rotating arm is hinged to the front end of the lower die base. The upper die comprises an upper die base located above the lower die base. A through groove which is through in a front-and-back mode is formed in the center of the upper die base. Male dies are arranged at the front ends of the parts, located on the two sides of the through groove, of the upper die base respectively. A rotating shaft is installed between the male dies. The wheel is arranged on the rotating shaft. According to the flexible bending die with the wheel preventing deformation, due to the fact that the wheel is arranged between the male dies, in the bending process, the deforming position of the condensing pipe floats along with the cylindrical wheel, the damp generated in deformation is eliminated, and the defect that when the existing outer refrigerator plate is in bending production, hard spots are generated on the condensing pipe or bending, shrinking and deforming are generated on the condensing pipe is overcome.

Description

technical field

[0001] The invention belongs to the technical field of metal bending molds, in particular to a bending mold used for producing refrigerator boxes. Background technique

[0002] Modern refrigerator condensers generally change the external formation to the internal formation. In the manufacture of existing refrigerators, under the premise of not affecting the cooling efficiency, the condensation pipe is fixed on the inner side of the outer box of the refrigerator with aluminum foil tape, and then U-shaped bending is performed; the cost is reduced, and the appearance and safety of the refrigerator are improved. However, when the U-shaped bending is performed, the condenser tube often bends and deforms, resulting in defective products. Contents of the invention

[0003] In order to solve the problem that the condensation pipe is prone to bending and deformation during the bending production of the existing refrigerator outer box board, the present invention pr...
