Detailed description of the invention
Technical scheme is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
Refer to Fig. 1 to show the embodiment of the present invention 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 mould includes the upper cover plate 1, train wheel bridge 17 and the upper de-plate 14 that are sequentially connected with from top to bottom, and train wheel bridge 17 is connected with punching pin 12, and upper de-plate 14 is provided with punching pin pilot hole, is connected to elastic component 15 between upper de-plate 14 and upper cover plate 1; Counterdie includes the lower shoe 3 and the lower bolster 11 that are sequentially connected with from bottom to top, the punching pin being inlaid with energy vertical direction motion on described lower bolster 11 enters son 8, punching pin enters the air ring being connected below being fixed in the internal chamber of lower shoe 3 of son 8 and lower elastic component 4, punching pin enters son 8 and is provided with gas hole 801, and gas hole 801 is connected with the gas outlet of air ring.
In the present embodiment, take out in tooth mould and be provided with air ring, this takes out tooth mould punching when taking out tooth hole, punching pin 12 moves downward and applies a force to punching pin and enters on son 8, punching pin enters son 8 and moves downward, air ring is discharged owing to being subject to the gas hole that after punching pin enters sub pressure down, its internal gas enters on son by punching pin, and in gas hole, expellant gas blows to sheet metal part surface and the chip near Shang Chouya hole, this surface is blown away, thus ensureing the punching pin suface processing quality to taking out tooth hole. Completing and during punching pin return when taking out the punching of tooth hole, owing to atmospheric pressure is 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 and prepares.
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 the internal chamber of lower shoe 3, the lower end that the upper end of stacked air ring 6 and punching pin enter son 8 is affixed, and the gas outlet of stacked air ring 6 enters the gas hole of sub 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 rapidly separated 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 enters is connected to guide pad 7 between son 8 and lower elastic component 4, the lower surface of guide pad 7 is affixed with the upper end of stacked air ring 6, and guide pad 7 is communicated with hole 701. Guide pad 7 moves up and down in the internal chamber of lower shoe 3, the then equal keeping parallelism state in the upper surface of elastic component 4 and stacked air ring 6, so that being more uniformly stressed everywhere of elastic component 4 and stacked air ring 6, reduce both local pressure concentration phenomenon respectively, extend both service life. Wherein, intercommunicating pore 701 is connected for the gas hole that the gas outlet of stacked air ring 6 enters son 8 with punching pin.
Continue referring to Fig. 1; punching pin enters the lower surface of son 8 and upwards caves in the buffer air chamber having the gas outlet with stacked air ring 6 to be connected; this buffer air chamber is equivalent to the extension of stacked air ring 6 volume; more gas can be held; so that the control that surface of the work is blown, moreover it is possible to part chip entrained when gas enters into stacked air ring 6 is temporarily deposited in this buffer air chamber, thus avoiding chip to enter in stacked air ring 6; effective protection aquiclude stacked air ring 6, extends its service life.
Take out in the process of tooth hole at punching sheet metal part, punching pin 12 drives punching pin to enter son 8 and moves downward, for preventing punching pin from entering sub 8 excessive movements, lower elastic component 4 is set on a limited block 5, the lower surface of limited block 5 and lower shoe 3 are affixed, and the upper surface concave downward of limited block 5 has for holding and the containing cavity of affixed stacked air ring 6. 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 position of lower section, can not only prevent punching pin 12 from the excessive punching of workpiece is taken out tooth, that avoids sheet metal part takes out tooth bore deformation, also it is avoided that lower elastic component 4 over-compressed lost efficacy, extends the service life of lower elastic component 4.
Owing to taking out in the process of tooth hole at punching sheet metal part, punching pin enters son 8 to be needed to move up and down, then enter the sub 8 sub-pilot holes that enter matched with punching pin and just have abrasion, in order to ensure that punching pin enters son 8 accurate guiding in the course of the work, as shown in Figure 1, being inlaid with insert 9 on lower bolster 11, insert 9 is provided with into sub-pilot hole. When in insert 9 when entering sub-pilot hole serious wear, the insert 9 more renewed at any time, namely insert 9 can make standard consumable accessory, so not only reduce dismounting 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 shown in Figure 1, being connected with several guide pillar 2 on upper cover plate 1, the quantity of guide pillar 2 is determined according to field condition, and lower shoe 3 is provided with several guide pillar pilot hole 301 matched with guide pillar 2 or guide pin bushing.
In order to avoid upper cover plate 1 and lower shoe 3 compressive deformation, being provided with upper padding plate 16 between upper cover plate 1 and train wheel bridge 17, the lower surface of upper padding plate 16 contacts cooperation with the upper surface of punching pin 12, is provided with lower bolster 13 between lower bolster 11 and lower shoe 3.
Additionally, the lower surface of lower shoe 3 is connected with counterdie foot 18, in order to the whole series take out the fixed installation of tooth mould.
Obviously, the above embodiment of the present invention is only used to the clear example of the present invention that illustrates, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, 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 any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within the protection domain of the claims in the present invention.
