Description
Technical Field
The utility model belongs to the automated manufacturing field, specifically speaking relates to a mould a hole shaping chamfer device.
Background
At present in the automobile manufacturing field, most motorcycle types basically all have the rear bumper to be provided with the radar hole for the installation radar of backing a car, the motorcycle type front bumper that has even can set up the radar hole on also, is used for installing leading radar. The radar hole all needs to produce the chamfer at the drill way border that has lacquer painting one side when the shaping to this chamfer can not be the cutting formation, also need remain car lacquer in chamfer department, otherwise the radar is not only pleasing to the eye inadequately after installing in the radar hole, and more serious is that the lacquer begins to fall from the drill way border in radar hole easily.
The radar hole on the existing automobile bumper is formed by stamping, a stamping die of the radar hole generally comprises two parts, namely an upper die with a chamfer-shaped step and a lower die matched with the upper die, the upper die and the lower die are respectively positioned at the upper side and the lower side of the automobile bumper when the radar hole is processed, the upper side is used for detecting the automobile paint surface, and the lower side is used for detecting the automobile paint surface without the paint surface. And by stamping the upper die and the lower die, the chamfer at the edge of the radar hole is pressed by the chamfer-shaped step on the upper die while the radar hole is punched. The biggest defect of this kind of equipment and chamfer shaping mode now is exactly that it is special only to be able to special plane, processes the radar hole of different apertures or all need switch different mould heads when needing to adjust chamfer angle, and equipment flexibility is poor, and especially when some motorcycle types stop production, the radar hole processing equipment of specific size will all be abandoned and eliminated on this motorcycle type, causes manufacturing cost's increase. Changing different die heads affects production efficiency, and in general, the flexibility of the equipment is poor.
The above-mentioned apparatus is poor in flexibility, which is produced by rigid production and flexible production, the rigid production produces mass and standardized products, only products with the same parameters can be produced on one production line, and when the parameters of the products need to be adjusted, the mold or some other apparatus needs to be replaced. Unlike rigid production, flexible production simply means that products meeting different requirements can be manufactured on one production line, customization can be achieved, and flexible production is the trend of future manufacturing industry.
Disclosure of Invention
The utility model discloses an aim at be exactly to above-mentioned prior art not enough, provide a chamfer size is adjustable, and a hole chamfer forming device is moulded to floating constant voltage of chamfer dynamics adjustable.
The utility model adopts the technical scheme as follows:
