Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is stated in detail.
Referring to figs. 1 to shown in Fig. 5, the present embodiment proposes a kind of punching die being conveniently replaceable drift, this punching die
Mainly include upper mold portion, lower mold portion and the above-mentioned drift being conveniently replaceable, like the prior art, upper mold portion to
Under include upper bolster 10, upper padding plate 20, fixed plate 30, baffle plate 40, stripper plate 50, wherein, upper bolster 10, upper padding plate successively
20th, fixed plate 30 is fixed together, and baffle plate 40, stripper plate 50 are fixed together, fixed plate 30 and baffle plate 40
Between be connected with spring so that can be movable relatively between fixed plate 30 and baffle plate 40.Under lower mold portion includes from top to bottom successively
Template 60, lower bolster 70 and die shoe 80, lower template 60 is provided with the punching concave die corresponding with described drift, and lower template 60 is used
Treat punched material in placement.Certainly, for improving the precision of upper mold portion and lower mold portion cooperation, it is additionally provided with guide frame therebetween,
Drift and punching concave die is made to can be good at coordinating.
Particularly, for realizing being conveniently replaceable the effect of drift, the present embodiment punching die also includes insert 91, lower insert
92 and upper bolt, lower bolt.Upper insert 91 is provided with bore of the punch 1, as shown in figure 4, lower insert 92 is provided with bore of the punch two
922, as shown in figure 5, bore of the punch 1 and bore of the punch 2 922 are fitted with drift, as shown in Figure 2；Fixed plate 30 is provided with through hole one
31, baffle plate 40 is provided with through hole 2 42, and stripper plate 50 is provided with through hole 3 53, as shown in Figure 3；Upper insert 91 pass through through hole 1,
After through hole 2 42, through hole 3 53, by using being above bolted to the bottom surface of upper padding plate 20, now the bottom surface of upper padding plate 20 is blocked
Punch tip, thus fixing the position of drift, now going up insert 91 and being located at through hole 1, the inside of through hole 2 42, upper bolt
Head be located at the inside of through hole 2 42, and during fixed plate 30 and baffle plate 40 relative motion, upper insert 91 and upper spiral shell
Bolt all will not interfere with lower insert 92；Lower insert 92 is located at the inside of through hole 3 53 and using lower bolt connection in baffle plate 40
Bottom surface, the head of lower bolt is located at the inside of through hole 3 53, treats punched material to avoid interference with.
What drift was conveniently replaceable focus on is installed insert 91 and can directly be completed on punch press with the process of lower insert 92,
Do not need to disassemble upper mold portion from punch press, be discussed in detail below by way of the concrete steps changing drift.
After the phenomenon that excessive wear, fracture etc. need replacing in the old drift in punching die, first with punch press
Ensure that upper mold portion is held apart at lower mold portion, using dismantling device by lower Bolt dismantling, after lower Bolt dismantling finishes, lower insert 92
Dropped from through hole 3 53 by own wt, and eventually disengage from upper mold portion；Then inserting dismantling device will be upper in through hole 3 53
Bolt dismantling, after upper Bolt dismantling finishes, upper insert 91 is fallen to through hole three by own wt from through hole 1, through hole 2 42
53, and eventually disengage from upper mold portion, now just easily can take out old drift from upper insert 91.
When more renewing drift, first the top of drift is inserted in the bore of the punch 1 of upper insert 91, and by upper insert
91 are placed in inside through hole 1 and through hole 2 42 through through hole 3 53, to be reconnected upper insert 91 in upper using upper bolt
The bottom surface of backing plate 20, then descends insert 92 to be placed in and is inserted into rushing of lower insert 92 in through hole 3 53 and simultaneously by the bottom of new drift
In head bore 2 922, using lower bolt, lower insert 92 is reconnected in the bottom surface of baffle plate 40, just can enter again after installing
Row punch operation, it is significant to note that, when drift does not work, its underpart can be completely disposed in bore of the punch 2 922, to avoid
Punched material is treated in scraping.Whole Renewal process, one is just operable to complete, and installs and dismantles all simple, easy to implement, saves
Time, improve replacing efficiency.Because upper insert 91 is located at through hole 1, through hole 2 42 inside and it needs to pass through through hole 3 53,
Therefore, in the present embodiment, through hole 1, through hole 2 42, the cross-sectional area of through hole 3 53 increase, successively to further facilitate operation
The installation of personnel and dismounting.
Specifically, in the present embodiment, upper insert 91 and lower insert 92 all employ the rectangular structure of easy processing manufacture, and
And for mitigating abrasion, between the side of upper insert 91, all process circular arc camber and the side of lower insert 92 between.Certainly, at this
In the other embodiment of utility model, for the simple drift of some structures, also can adopt completely identical in structure upper insert 91
With lower insert 92, with reach reduce insert species effect.
Specifically, the present embodiment is provided with, in upper insert 91, the installing hole one coordinating with upper bolt, and the bottom surface of upper padding plate 20 sets
There is the screwed hole one with the cooperation of upper bolt, the screw rod of upper bolt passes through installing hole one and the cooperation of screwed hole one screw thread；Lower insert 92
It is provided with the installing hole two with the cooperation of lower bolt, the bottom surface of baffle plate 40 is provided with the screwed hole two with the cooperation of lower bolt, lower bolt
Screw rod passes through installing hole two and the cooperation of screwed hole two screw thread.
For avoiding upper bolt and the head of lower bolt to cause interference, in the present embodiment installing hole one and installing hole two be heavy
So that the head of upper bolt is located inside installing hole one, the head of lower bolt is located to be installed inside two head bore.Certainly in this practicality
In new other embodiment, if not adopting counter sink scheme, also can be by reducing the thickness of upper insert 91, to ensure through hole
The accommodation space of the head of bolt is left inside 2 42, and by reducing the thickness of lower insert 92, to ensure through hole 3 53
The accommodation space of the head of lower bolt is left in inside.
In order to corresponding with above-mentioned counter sink, in the present embodiment, upper bolt and lower bolt are all using being easy to fastening, be difficult to slide
The hexagon socket head cap screw at angle, and in order to reduce bolt model, omit the time distinguishing bolt, in the present embodiment, adopt specifications and models phase
Same upper bolt and lower bolt.
Above example is only in order to illustrating the technical solution of the utility model, rather than is limited；Although with reference to front
State embodiment this utility model has been described in detail, for the person of ordinary skill of the art, still can be right
Technical scheme described in previous embodiment is modified, or carries out equivalent to wherein some technical characteristics；And these
Modification or replace, do not make appropriate technical solution essence depart from this utility model technical scheme required for protection spirit and
Scope.
