Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Usually here in attached drawing description and
The component of the utility model embodiment shown can be arranged and be designed with a variety of different configurations.Therefore, below to attached
The detailed description of the embodiments of the present invention provided in figure is not intended to limit the range of claimed invention,
But it is merely representative of the selected embodiment of the utility model.
Referring to Figures 1 and 2, the utility model discloses a kind of sheet metal component hole flanging mold comprising:
Upper mold 1, the upper mold 1 are provided with formed punch 3, and the formed punch 3 includes shaft 301 and coaxial arrangement under shaft 301
The diameter of the red needle 302 at end, the red needle 302 is less than shaft 301；
Lower die 2, the corresponding formed punch 3 of the lower die 2 offer punching, and the punching hole diameter is greater than 301 diameter of shaft, in punching
It is equipped with mold insert 4 movable up and down, the corresponding red needle 302 of the mold insert 4 is provided with waste discharge through-hole 8, and 4 side of mold insert is provided with convex
The side of platform 401, corresponding 4 lower end of mold insert of lower die 2 is provided with plummer 6, and the outer surface of mold insert 4 is arranged with spring 5, the spring
5 one end abuts boss 401, the other end abuts plummer 6, so that the concordant punching in the upper end of mold insert 4.
In this way, red needle 302 and the cooperation of mold insert 4 complete pre-punched hole processing and are pressed into punched scrap to arrange in 1 downlink of upper mold
Useless through-hole 8 and be discharged downwards, be about to mold insert 4 under shaft 301 later and depress and complete flange processing, last upper mold between punching
1 uplink, the upper end of mold insert 4 abut flange and are ejected by the effect of spring 5.The utility model is once past by press device
The hole flanging production that can complete sheet metal component is returned, high production efficiency, wherein mold insert 4 has both material returned effect, and punched scrap is rushed
Needle 302 is pressed into waste discharge through-hole 8 and is discharged downwards, will not be adhered on flange, and processing quality is high, can save process, and positioning is avoided to miss
Hole flanging defect caused by difference improves the precision of hole flanging, practical.
For the ease of after pre-punched hole, sheet metal component uses circular cone to lower flange between the red needle 302 and shaft 301
Face or spherical transition make formed punch 3 gradually expand sheet metal component when contacting sheet metal component, can avoid sheet metal component cracking.
The hole flanging mold of the utility model, in a non-operative state when, the lower end of mold insert 4 extends in plummer 6, and makees
The lower end of mold insert 4 can be pierced by plummer 6 when industry, and punched scrap is expelled directly out by waste discharge through-hole 8, will not be accumulated and be blocked up in carrying
In the upper end of platform 6 or spring 5.In order to accelerate waste discharge efficiency, preferably, the waste discharge through-hole 8 includes being located at 4 upper end of mold insert
And the first duct 801 for being adapted to 302 diameter of red needle and 4 lower end of mold insert is extended to from 801 end of the first duct and diameter is greater than
Second duct 802 in the first duct 801.For cooperating red needle 302 to complete pre-punched hole processing, punching later is useless in the first duct 801
Material enters the second duct 802, can accelerate the velocity of discharge because frictional force reduces.The length in the first duct 801 is greater than or equal to punching
The length of needle 302, such red needle 302 cannot pass through the first duct 801 enter the second duct 802, and then be not present backhaul when by
The problem of shearing force is broken.
As shown, the punching includes the molding duct and installation duct of coaxial arrangement, the molding hole from top to bottom
Road is for cooperating formed punch 3 to complete flange processing, and the diameter in the installation duct is greater than molding duct, and the upper end of the mold insert 4 is
The diameter of the profiled section 402 being adapted to molding duct, the boss 401 is adapted to installation duct, and mold insert 4 is held on the top of spring 5
The shaft shoulder for forming boss 401 in 4 upper end of mold insert abuts the end in installation duct, so make the upper end of mold insert 4 at
The upper end in type hole road keeps concordant.The lower end in installation duct is equipped with locking nut and detachably so as to form plummer 6, described
The lower end of mold insert 4 is pierced by from locking nut.It is connected through a screw thread between locking nut and installation duct, mold insert 4 is in cylinder
The upper and lower side of boss 401 is set as the circular tube structure being adapted to molding duct, in order to process.In view of mold insert 4 needs
The stamping press of receiving is larger, preferably, the spring 5 is heavily loaded Rectangular Spring, to ensure use intensity.In this way, mold insert 4
It can be up and down under the slide-and-guide effect in boss 401 and installation duct.
Further, the upper end of the upper mold 1 corresponds to formed punch 3 and is provided with quick-changing mechanism, and the formed punch 3 can be by changing planes fastly
The fast quick-detach of structure.As shown, the upper end of the formed punch 3 is provided with the head that diameter is greater than shaft 301, the upper mold 1 includes
Upper padding plate and upper clamp plate, the upper clamp plate offer the third duct being adapted to the shaft 301 of formed punch 3, corresponding the on upper padding plate
Three ducts offer the 4th duct that diameter is greater than 3 head of formed punch, and upper mold 1 is in being detachably equipped with fastening screw in the 4th duct
7, the formed punch 3 can be packed into third duct and locked by fastening screw 7 from the 4th duct.
Workpiece is placed between upper mold 1 and lower die 2 by the hole flanging mold of the utility model, and upper mold 1 passes through press device downlink
And cooperate the first duct 801 of 4 upper end of red needle 302 and mold insert and complete pre-punched hole, since mold insert 4 is using heavily loaded Rectangular Spring branch
Support, therefore before the upper end of red needle 302 does not abut mold insert 4, mold insert 4 can be kept fixed without downlink.Punching is come downwards to formed punch 3
After the end abutment workpiece of needle 302, formed punch 3 is gradually expanded the pre-punched hole on workpiece by circular conical surface or spherical surface and makes workpiece gradually
Mold insert 4 is pushed to lower flange, while by the flange, so flange height neat and consistent.To the end abutment mold insert of red needle 302
Behind 4 upper end, downlink under the action of formed punch 3 of mold insert 4, and the flange on workpiece is total through shaft 301 and 801 inner wall of the first duct
Same-action molding.Later 1 uplink of upper mold and drive formed punch 3 to exit, mold insert 4 is under the action of heavily loaded Rectangular Spring and boss 401
It releases, is automatically performed with 3 uplink synchronization of formed punch, while by the flange in duct is formed under the guiding role of installation duct cooperation
Material returned action.Since the pushing to mold insert 4 relies primarily on the changeover portion between the end of red needle 302 and shaft 301, abrasion
It is larger, replacement formed punch 3 may be frequently necessary to, by quick-changing mechanism can with quick-replaceable formed punch 3, without dismantle upper padding plate, on
The structures such as clamping plate, it is easy to use, it is practical.
Above-described embodiment is the preferred embodiment of the utility model, and the utility model can also have other embodiments.Ability
The technical staff in domain can also make equivalent deformation or replacement without departing from the spirit of the present invention, these equivalent changes
Type or replacement are all contained in range set by the claim of this application.
