Abstract
The utility model discloses a kind of molds of inner cavity deformation when limitation clutch case punching, including stripper, movable inner cavity limited block is uniformly arranged on the clutch case mounting surface of the stripper, the inner cavity limited block is located on same Radius annulus position, setting position can be adjusted according to clutch case size along clutch case radial direction, in punching, inner cavity limited block just withstands the interior lumen type face on clutch case, it is indeformable to limit the punching of clutch case inner cavity, the inner cavity limited block is L-shaped, it is connect on the outside of its long side with the interior lumen type face paste of clutch case, the inner cavity limited block is three.The mold of this structure can be realized quickly to be adjusted on lathe, improves the efficiency that repairs a die, and saves the cost that repairs a die, and is haved the function that limit the deformation of clutch case inner cavity, is guaranteed the position degree in the original forming dimension of clutch case and hole.
Description
Technical field
The utility model belongs to clutch case hole punching positioning device field, and in particular to when a kind of limitation clutch case punching
The mold of inner cavity deformation.
Background technique
In automotive field, as the structure updating of clutch product and mold manufacturing procedure are reduced, clutch case at present
Hole location require it is relatively previous more stringent, since clutch case is a kind of unique covering of shape, punch process
, there is moment rebound in effect of the inner cavity by impact force, and inner cavity occurs elasticity or plastic deformation, leads to the position of its punching after punching
It sets and changes, to influence the position degree in hole, frequency of maintenance is very high, and maintenance cost increases, while influencing the production effect of product
Rate is not timely completed qualified product delivery.
Utility model content
The purpose of this utility model is to overcome the deficiencies of existing clutch case mold, provide a kind of limitation clutch case
The mold that inner cavity deforms when punching.This mold can smoothly complete a processing flow, realize and quickly adjust on lathe, raising repairs a die
Efficiency is saved the cost that repairs a die, while can be adjusted according to the size of clutch case, and limitation clutch case inner cavity is reached
The effect of deformation guarantees the position degree in the original forming dimension of clutch case and hole.
The utility model is achieved through the following technical solutions:
The mold of inner cavity deformation when a kind of limitation clutch case punching, including
Upper die holder and lower die holder；
The upper die holder lower surface is sequentially with upper padding plate, punch retainer and stripper from top to bottom, and upper die holder is by interior
It is sequentially with inner guiding post and limited post outward, clutch case is installed in stripper upper surface, and punch retainer is equipped with punch-pin；
The lower die holder upper surface is sequentially with lower bolster and die block from bottom to top, and die block is equipped with recessed
Mould is equipped with mesoporous positioning, positioning mold insert and jigger pin, lower die holder on lower bolster from inside to outside and cushion block is arranged below；
The cavity plate and punch-pin cooperate；
Movable inner cavity limited block is uniformly arranged on the clutch case mounting surface of the stripper, the inner cavity limited block is set
On same Radius annulus position, in punching, inner cavity limited block just withstands the interior lumen type face of clutch case.
The inner cavity limited block is L-shaped, connects on the outside of long side with the interior lumen type face paste of clutch case.
The inner cavity limited block is three.
Limited block fixed counterbore in inner cavity is set on the stripper, and inner cavity limited block pedestal is screwed on counterbore.
The utility model has the beneficial effects that the cavity plate and punch-pin cooperate, clutch case is impacted masterpiece by upper die holder
With punching is completed, limited by the clutch case mounting surface in stripper with movable inner cavity is uniformly arranged on Radius annulus position
Position block guarantees that inner cavity limited block when punching just withstands the interior lumen type face of clutch case, prevents clutch case inner cavity from being impacted
There is moment rebound and elasticity or plastic deformation occurs in the effect of power, and the position of its punching after being punched is caused to change, thus
The position degree for influencing hole, prevents clutch case from not blocked by stripper in the punching material returned, smoothly completes a processing flow, real
It is quickly adjusted on existing lathe, improves the efficiency that repairs a die, save the cost that repairs a die.Inner cavity limited block setting position can be according to clutch
The size of device lid is adjusted along clutch case radial direction, thus inner cavity deformation when reaching limitation clutch case punching
Effect guarantees the position degree in the original forming dimension of clutch case and hole.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram；
Fig. 2 is that the structural schematic diagram on stripper is arranged in inner cavity limited block in the utility model embodiment.
In figure, 1. upper die holder, 2. upper padding plate, 3. punch retainer, 4. stripper, 5. inner guiding post, 6. limited post, 7. punch-pin
8. 13. cushion block of inner cavity limited block 9. cavity plate, 10. die block, 11. lower bolster, 12. lower die holder, 14 jigger pin 15. is fixed

Specific embodiment
The content of the present invention is further elaborated with reference to the accompanying drawings and examples, but is not to the utility model
Restriction.
Embodiment:
As shown in Fig. 1 Fig. 2, it is a kind of limitation clutch case punching when inner cavity deformation mold, including
Upper die holder 1 and lower die holder 12；
1 lower surface of upper die holder is sequentially with upper padding plate 2, punch retainer 3 and stripper 4 from top to bottom, and upper die holder 1 is by interior
It is sequentially with inner guiding post 5 and limited post 6 outward, clutch case 17 is installed in 4 upper surface of stripper, and punch retainer 3 is equipped with convex
Mould；
12 upper surface of lower die holder is sequentially with lower bolster 11 and die block 10 from bottom to top, sets on die block 10
There is cavity plate 9, is equipped with mesoporous positioning 16, positioning mold insert 15 and jigger pin 14 from inside to outside on lower bolster 11, lower die holder 12 is set below
There is cushion block 14；
The cavity plate 9 cooperates with punch-pin 7；
Movable inner cavity limited block 8, the inner cavity limit are uniformly arranged on 17 mounting surface of clutch case of the stripper 4
Block 8 is located on same Radius annulus position, and in punching, inner cavity limited block 8 just withstands the interior lumen type face of clutch case 17.
The inner cavity limited block 8 is L-shaped, connects on the outside of long side with the interior lumen type face paste of clutch case 17.
The inner cavity limited block 8 is three.
Limited block fixed counterbore in inner cavity is set on the stripper 4, and limited block 8 pedestal in inner cavity is screwed in counterbore
On.
In use, determining that position and mould is arranged in inner cavity limited block 8 first according to the size and structure of clutch case 17
