Embodiment
The technical solution of the utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
Referring to described in accompanying drawing 1 and accompanying drawing 2, workpiece 5 can form sharp edge and burr 7 after being punched in the lower end of punching mouth.Referring to
Shown in accompanying drawing 3 and accompanying drawing 4, the quick device for removing workpiece punching mouth sharp edge and burr, including upper mould 1, be sheathed on it is right on mould 1
Upper mould 1 is oriented to stripper plate 2, the lower mould 3 corresponding with upper mould with positioning action.The lower upper end of mould 3 vertically be provided with
The corresponding round platform 4 in hole 6 to be processed, the height of round platform 4 is less than the axial depth in hole 6 to be processed.The height of round platform 4 can be to treat
Process the axial length in hole 6 0.5 to 0.9 times, it is preferred that the height of round platform 4 can be the 0.8 of the axial length in hole 6 to be processed
Times.Meanwhile, the upper surface diameter of round platform 4 is less than the diameter in hole 6 to be processed, and the bottom surface diameter of round platform 4 is more than the straight of hole 6 to be processed
Footpath, but the bottom surface diameter of round platform 4 is no more than the maximum limit of size in hole 6 to be processed.The bottom surface diameter of round platform 4 is than to be processed
The diameter big 0.1mm to 0.2mm in hole 6, it is preferred that diameter big 0.15mm of the bottom surface diameter than hole to be processed.
The bottom surface of wherein upper mould 1, the upper surface of round platform 4, above lower mould 3 it is horizontal plane, is removed using the present apparatus
When sharp edge and burr 7, sharp edge and burr 7 are towards the bottom of the round platform.Rounding can be set with the lower junction of mould 3 in round platform 4, can
So that the edge after blunt-edged or burr 7 is gentler.
As shown in accompanying drawing 5 and accompanying drawing 6, the sharp edge and burr 7 of the workpiece to be processed 5 need to be put towards the bottom of round platform 4 to
After on lower mould 3, hole 6 to be processed is sheathed on round platform 4.Because the bottom surface diameter of round platform 4 is more than the diameter in hole 6 to be processed, institute
There is gap between above now workpiece to be processed 5 and lower mould 3.
As shown in accompanying drawing 7 and accompanying drawing 8, when upper mould 1 is pressed downward workpiece to be processed 5, due to the axial depth in hole 6 to be processed
More than the height of round platform, workpiece to be processed 5 can be depressed into the bottom of round platform 4 by upper mould 1, while the bottom surface of upper mould 1 and round platform 4
Also there is gap between upper surface, therefore the present apparatus can fully extrude the sharp edge and burr 7 at the edge of hole 6 to be processed.
As shown in accompanying drawing 9 and accompanying drawing 10, hole 6 to be processed is before blunt-edged and burr 7, the lower edge tool in hole 6 to be processed
There are sharp edge and burr 7, it is relatively more crude.After blunt-edged and burr 7 then than shallower.Therefore, the present apparatus can be fast and effeciently
Sharp edge and burr 7 are removed, the quality and efficiency of the potential safety hazard of production, lifting blunt-edged and burr is reduced.
Above-described embodiment is only to illustrate technical concepts and features of the present utility model, and its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover protection domain of the present utility model it
It is interior.
