Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Refer to Fig. 1 show this utility model embodiment and take out a better embodiment of tooth mould.
The present embodiment is that one takes out tooth mould, as it is shown in figure 1, include upper die and lower die；Upper mold is from top to bottom
Including the upper cover plate 1 being sequentially connected with, train wheel bridge 17 and upper de-plate 14, train wheel bridge 17 is connected with punching pin 12,
Upper de-plate 14 is provided with punching pin pilot hole, and connecting between upper de-plate 14 and upper cover plate 1 has upper elastic component 15；Under
Mould includes lower shoe 3 and the lower bolster 11 being sequentially connected with from bottom to top, described lower bolster 11 is inlaid with and can erect
Nogata enters son 8 to the punching pin of motion, and punching pin enters the lower section connection of son 8 the internal chamber being fixed in lower shoe 3
In air ring and lower elastic component 4, punching pin enters son and 8 is provided with gas hole 801, and gas hole 801 is given vent to anger with air ring
Mouth is connected.
In the present embodiment, taking out in tooth mould and be provided with air ring, this takes out tooth mould punching when taking out tooth hole, punching pin 12
Moving downward and apply a force to punching pin and enter on son 8, punching pin enters son 8 and moves downward, and air ring is owing to being subject to
The gas hole that enter the pressure down of son to punching pin after, its internal gas enters on son by punching pin is discharged, row in gas hole
The gas gone out blows to sheet metal part surface and the chip near Shang Chouya hole, this surface is blown away, thus ensures punching
Son is to the suface processing quality taking out tooth hole.Complete and during punching pin return, due to atmospheric pressure when taking out the punching of tooth hole
More than air ring internal gas pressure, air enters in air ring by the gas outlet of air ring, takes out tooth hole for the punching next one
Prepare.
Concrete, as it is shown in figure 1, air ring is stacked air ring 6, the lower end of stacked air ring 6 is fixed in down
In the internal chamber of base plate 3, the lower end that the upper end of stacked air ring 6 and punching pin enter son 8 is affixed, and stacking
The gas outlet of formula air ring 6 enters the gas hole of son 8 and connects with punching pin.Compared with monolayer air ring, stacked air ring 6
Volume is bigger, it is possible to store more air, can produce bigger air stream when blowing, it is simple to chip is fast
Speed departs from sheet metal part surface.
In order to ensure that elastic component 4 and stacked air ring 6 are more uniformly stressed everywhere, as it is shown in figure 1, punching pin
Enter to be connected between son 8 and lower elastic component 4 and have guide pad 7, the lower surface of guide pad 7 and stacked air ring 6
Upper end is affixed, and guide pad 7 is communicated with hole 701.Guide pad 7 is transported in the internal chamber of lower shoe 3 up and down
Dynamic, then the equal keeping parallelism in the upper surface of elastic component 4 and stacked air ring 6 state, so that elastic component 4 He
Being more uniformly stressed everywhere of stacked air ring 6, reduces both local pressure concentration phenomenon respectively, extends two
The service life of person.Wherein, intercommunicating pore 701 is for entering son 8 by the gas outlet of stacked air ring 6 and punching pin
Gas hole be connected.
Continuing referring to Fig. 1, punching pin enters the lower surface of son 8 and upwards caves in and have and the gas outlet of stacked air ring 6
The buffer air chamber being connected, this buffer air chamber is equivalent to the extension of stacked air ring 6 volume, can accommodate more
Many gas, in order to the control that surface of the work is blown, moreover it is possible to when gas is entered into stacked air ring 6
Entrained part chip is temporarily deposited in this buffer air chamber, thus avoids chip to enter into stacked air ring 6
In, effective protection aquiclude stacked air ring 6, extend its service life.
Punching sheet metal part take out tooth hole during, punching pin 12 drives punching pin to enter son and 8 moves downward, and is anti-
Only punching pin enters sub 8 excessive movements, and lower elastic component 4 is set on a limited block 5, the lower surface of limited block 5
Affixed with lower shoe 3, the upper surface concave downward of limited block 5 has for accommodating and affixed stacked air ring 6
Containing cavity.When guide pad 7 moves downward and its lower surface touches the upper surface of limited block 5, punching pin
12 and punching pin enter son 8 and will be moved to the extreme positions of lower section, excessive to workpiece of punching pin 12 can not only be prevented
Tooth is taken out in punching, it is to avoid sheet metal part take out tooth bore deformation, moreover it is possible to avoid lower elastic component 4 over-compressed to lose efficacy,
Extend the service life of lower elastic component 4.
Due to punching sheet metal part take out tooth hole during, punching pin enter son 8 need move up and down, then with punching
Son enters the sub 8 sub-pilot holes that enter matched and just has abrasion, in order to ensure that punching pin enters son 8 in the course of the work
Accurate guiding, as it is shown in figure 1, be inlaid with insert 9 on lower bolster 11, insert 9 is provided with into sub-guiding
Hole.When in insert 9 when entering sub-pilot hole serious wear, the insert 9 the most more renewed, i.e. insert 9 can be done
One-tenth standard consumable accessory, the most not only reduces and dismounts maintenance time, moreover it is possible to reduce manufacturing cost.
In order to be further ensured that punching pin 12 and punching pin enter matched moulds degree of accuracy between son 8, as it is shown in figure 1, upper
Being connected with several guide pillar 2 on cover plate 1, the quantity of guide pillar 2 determines according to field condition, and lower shoe 3 is provided with
Several guide pillar pilot holes 301 matched with guide pillar 2 or guide pin bushing.
In order to avoid upper cover plate 1 and lower shoe 3 compressive deformation, it is provided with between upper cover plate 1 and train wheel bridge 17
Backing plate 16, the lower surface of upper padding plate 16 contacts cooperation, lower bolster 11 and lower shoe with the upper surface of punching pin 12
Lower bolster 13 it is provided with between 3.
Additionally, the lower surface of lower shoe 3 is connected with lower mold foot 18, in order to the whole series take out the fixing peace of tooth mould
Dress.
Obviously, above-described embodiment of the present utility model is only used to understand the act that explanation this utility model is made
Example, and it is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field
For, can also make other changes in different forms on the basis of the above description.Here without
Also cannot all of embodiment be given exhaustive.All made within spirit of the present utility model and principle
Any amendment, equivalent and improvement etc., should be included in this utility model scope of the claims it
In.
