Embodiment Construction

[0016] Describe an embodiment below in conjunction with accompanying drawing, the present invention is further described.

[0017] Embodiment: In the figure, the refrigerator door panel hemming bending mold includes an upper template 3 and a lower template 37, and the upper template 3 is symmetrically fixed with two drive blocks 11 sequentially from the outside to the inside, and the lower template 37 is symmetrical There are two large slides 18, and each large slide 18 is fixed with a traction block 15 and a bending bar 17 from the outside to the inside. The bending bar 17 is provided with a curved surface. When the mold is closed, the outer surface of the driving block 11 and the traction block The inner surface of 15 cooperates, the end of the outer surface of the driving block 11 is provided with a first guiding slope 21 , and the end of the inner surface of the traction block 15 is provided with a second guiding inclined surface 22 . The lower template 37 is provided with...

Abstract

The invention discloses an edging and bending die for a refrigerator door panel. The edging and bending die comprises an upper die plate and a lower die plate. A material pressing plate is arranged in the middle of the upper die plate and provided with a discharging mechanism. A material supporting plate is arranged on the lower die plate, and two bending mechanisms are fixed to the positions, at the two sides of the material pressing plate, of the upper die plate. According to the edging and bending die for the refrigerator door panel, due to the fact that shaping wheels used for fast bending a refrigerator door and a rolling shaping shaft are adopted, the surface of the refrigerator door panel is prevented from being pulled to be damaged in the bending process, the shaping wheels at the two sides of the shaping shaft enable the bevel ends of the refrigerator door to form flat wrap angles, and therefore the wrap corners of the refrigerator door panel are flat and the wrap corners can prevent the refrigerator door from deforming after being shaped. Due to the fact that a pressure assembly exerts pressure on the shaping shaft, the forming speed of the die is improved, and meanwhile the shaping shaft is prevented from being scrapped due to bending and deforming after long-time use. The matching position of the pressure mechanism and the shaping shaft is provided with a rolling pressure rolling shaft, the sliding friction between the shaping shaft and the pressure assembly is converted into rolling friction, abrasion of the shaping shaft is further reduced, and the quality of the formed refrigerator door panel is further improved.

Description

technical field [0001] The invention relates to a mold, in particular to an edge-wrapping and bending mold for a refrigerator door panel. Background technique [0002] The cross-section of the refrigerator door is usually U-shaped, and its production method usually adopts stamping forming. However, the existing stamping forming process can only stamp the refrigerator door into a U-shape, and there is no solid end surface at the corner of the refrigerator door. This not only affects the appearance but also the stamped refrigerator door is easily deformed. Contents of the invention [0003] In order to solve the defects that the surface of the existing refrigerator door panel edge-wrapping bending mold is strained and the corners of the produced refrigerator door panel have no flat corners and the mold life is short, the invention provides a refrigerator door panel edge-wrapping bending mold. [0004] The technical solution adopted by the present invention to solve the tec...
