Automobile grill hot stamping process

Abstract

The invention provides a car grille hot stamping technology. The technology comprises the following steps: 1, making a hot stamped film which sequentially comprises a carrier, a stripping layer, a protection layer, a metal layer and a sticking layer from top to bottom; 2, selecting a stamping clamp: arranging a direction adjusting mechanism below the stamping clamp, wherein the direction adjusting mechanism can realize the adjustment of the X direction, the Y direction and the Z direction in the space; 3, heating silica gel of an upper die in the stamping process, pressing the silica gel to make the silica gel touch the hot stamped film in order to press the hot stamped film and compact the hot stamped film on the stamped surface of a grille component on the surface of a lower die; and 4, separating a stamped surface area and a non-stamped surface area, arranging the stamped surface to be a projecting structure, and dividing the whole grille component into a plurality of parts, and stamping the grille component. The hot stamping technology adapts to multiple form styles, has the advantages of short shaping time, provision of a bright surface effect, avoiding of toxic gases or wastewater generated in the electroplating process, energy saving, and environmental protection; and a stamping device has the advantages of small occupied space, small energy consumption and low development cost.

Description

technical field [0001] The invention relates to the technical field of hot stamping machine equipment, in particular to a hot stamping process for automobile grilles. Background technique [0002] With the development of the economy, people's pursuit of car quality is getting higher and higher, and the interior and exterior of the car are an important part of the quality and appearance; because hot stamping technology can provide various decorative effects, such as peach wood, carbon fiber and metal effects, so It is increasingly favored by various OEMs. At present, the hot stamping process is widely used in mainstream automobile manufacturers, mainly used in air-conditioning outlets, door slumps, central decorative frames, radiator grilles, signs, exterior trim strips and other parts; hot stamping technology can improve the quality of automobiles. The surface quality of interior and exterior decorations meets the diversified development needs of automobile interiors and ex...

Problems solved by technology

[0004] The current problem of using this method is that the shape of the current car grille is a relatively complex arc surface, and the hot stamping surfaces are not on the same plane, and the overall size of the grille is too long. The height difference between the point and the lowest point is huge, which is far greater than the tensile limit of conventional metal foil films, so it is impossible to achieve hot stamping
