Abstract
The utility model discloses a kind of automobile refuelling pipe hole-expansion punch mould, comprise punch body, described punch body center is provided with a mozzle, and described mozzle is the body of one end open, and opening part is positioned at the afterbody of punch body; The head of described punch body is provided with some drainage troughs uniformly, and described drainage trough is all through with the other end of mozzle.A cooling mozzle is set at punch body center, some drainage troughs are set at the head of punch body, make cooling fluid flow out from drift inside like this, concerning processing environment, more totally, cooling fluid is saved more; A pin mouth is increased at punch body afterbody, convenient when changing punch body, can more save time; Material, after Overheating Treatment, by making titanium nitride coating on surface, makes punch body smooth abrasion-proof more, promotes hardness, makes the service life of punch body longer, saves fund.
Description
Technical field
The utility model relates to a kind of diel of the automobile refuelling pipe mouth of pipe, is specifically related to a kind of automobile refuelling pipe hole-expansion punch mould.
Background technology
The automobile refuelling pipe mouth of pipe generally adopts mould punching shaping, and existing automobile refuelling pipe hole-expansion punch mould exists following problem: adopt outside mode of watering pouring cooling fluid more, and easy like this causing makes processing environment dirty and waste cooling fluid; The fixed form of plunger chip die adopts punch-center through hole screw to fix, and wasting time and energy, using inconvenience when changing plunger chip die; In order to promote case hardness and smoothness, then general employing heat treatment carrying out surface finish, and due to the precision problem of grinding machine, surface flatness is not easy to reach requirement.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of high rigidity, Fast Installation and clean automobile refuelling pipe hole-expansion punch mould of lowering the temperature.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of automobile refuelling pipe hole-expansion punch mould, comprise punch body, described punch body center is provided with a mozzle, and described mozzle is the body of one end open, and opening part is positioned at the afterbody of punch body; The head of described punch body is provided with some drainage troughs uniformly, and described drainage trough is all through with the other end of mozzle.The afterbody perfusion of cooling fluid from mozzle, all for cooling use, being entered, then being flowed out from the drainage trough of punch body head by described mozzle and drainage trough, cooling fluid is made to flow out from punch body inside like this, concerning processing environment, more totally, cooling fluid is saved more.
As further improvement of the utility model, the afterbody of described punch body is provided with a pin mouth, convenient when changing punch body, can more save time.
As further improvement of the utility model, the surface being positioned at described punch body is provided with one deck titanium nitride coating uniformly.Material, after Overheating Treatment, by making titanium nitride coating on surface, makes punch body smooth abrasion-proof more, promotes hardness, makes the service life of punch body longer, saves fund.
As further improvement of the utility model, described drainage trough is provided with the six roots of sensation.
The beneficial effects of the utility model are: arrange a cooling mozzle at punch body center, arrange some drainage troughs at the head of punch body, make cooling fluid flow out from drift inside like this, concerning processing environment, more totally, more save cooling fluid; A pin mouth is increased at punch body afterbody, convenient when changing punch body, can more save time; Material, after Overheating Treatment, by making titanium nitride coating on surface, makes punch body smooth abrasion-proof more, promotes hardness, makes the service life of punch body longer, saves fund.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is transverse cross-sectional view of the present utility model;
Fig. 3 is longitudinal sectional drawing of the present utility model;
Wherein: 1, punch body, 2, mozzle, 3, drainage trough, 4, pin mouth.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1 to Figure 3, a kind of automobile refuelling pipe hole-expansion punch mould, comprises punch body 1, and described punch body 1 center is provided with a mozzle 2, and described mozzle 2 is the body of one end open, and opening part is positioned at the afterbody of punch body 1; The head of described punch body 1 is provided with six roots of sensation drainage trough 3 uniformly, and described drainage trough 3 is all through with the other end of mozzle 2.The afterbody perfusion of cooling fluid from mozzle 2, all for cooling use, being entered, then being flowed out from the drainage trough 3 of punch body 1 head by described mozzle 2 and drainage trough 3, cooling fluid is made to flow out from punch body inside like this, concerning processing environment, more totally, cooling fluid is saved more.
The afterbody of described punch body 1 is provided with a pin mouth 4, convenient when changing punch body 1, can more save time.
The surface being positioned at described punch body 1 is provided with one deck titanium nitride coating uniformly.Material, after Overheating Treatment, by making titanium nitride coating on surface, makes punch body 1 smooth abrasion-proof more, promotes hardness, makes the service life of punch body longer, saves fund.
