Buoyance lift material lift part 31 is selectively attached in mounting hole 21, can be according to the abrasion of lower template 20 during actual use
Situation selects the buoyance lift material lift part 31 of appropriate length.
Certainly, in the other embodiment of the utility model, a buoyance lift material lift part 31 can also be only set, need to change
When becoming the length of buoyance lift material lift part 31, directly mill cuts buoyance lift material lift part 31, simple in structure, of low cost.
For the ease of effectively being supported to material strip 50, the material lift section of the buoyance lift material lift part 31 in the present embodiment is provided with edge
The groove 311 of buoyance lift material lift part 31 being radially arranged, in actual use, the edge of material strip 50 is fastened in groove 311,
It is simple in structure, it is easy to implement.Certainly, in the other embodiment of the utility model, groove 311 can also be set to buckle etc.
Structure, as long as other modes of texturing under the design of the utility model, both are within the protection scope of the present invention.
In the present embodiment, locked component includes washer 32 and locking member 33, and washer 32 is located at the bottom of buoyance lift material lift part 31
Portion is simultaneously locked by locking member 33, and the diameter of washer 32 is more than the diameter of mounting hole 21, convenient for buoyance lift material lift part 31 to be limited to
In mounting hole 21, and convenient for the length of buoyance lift material lift part 31 is adjusted.Preferably, the locking member 33 in the present embodiment is six
Angle screw, buoyance lift material lift part 31 is buoyance lift material lift pin, simple in structure, is easy to implement.Certainly, in other implementations of the utility model
In example, locking member 33 can also be set to the structures such as pin or rivet, pin or rivet are preferably easy-to-dismount knot here
Structure.
Shown in Fig. 1 and Fig. 2, the die assembly in the present embodiment further includes lower die holder 10 and reset assembly 40.
Wherein, lower template 20 is mounted on lower die holder 10, and location hole corresponding with mounting hole 21 11 is provided on lower die holder 10；Reset group
Part 40 is mounted on location hole 11 so that material lifting device 30 resets.During real work, due to isostructural by material strip 50
Pressure acts on, and buoyance lift material lift part 31 can be pressed down, through this embodiment in reset assembly 40 effect, can make material lift machine
Structure 30 resets.
Specifically, the location hole 11 in the present embodiment is threaded hole, and reset assembly 40 includes plug screw 41, elastic element
Plug screw 41 when installation, is mounted on the bottom of threaded hole by 42, mandril 43；Elastic element 42 is mounted in location hole 11 and is located at
The top of plug screw 41, mandril 43 are mounted on the top of elastic element 42, and mandril 43 is supported in the bottom of material lifting device 30.
Preferably, the elastic element 42 of the present embodiment is spring, certainly, in the other embodiment of the utility model, also
Elastic element 42 can be set to the structures such as resilient rubbber cushion, as long as other deformation sides under the design of the utility model
Formula both is within the protection scope of the present invention.
According to being that the above embodiments are known that：
30 main function of material lifting device of mold is：In high speed stamping, positioning material band 50 swing and raise material strip 50 from
Die sinking face, feeding function allows material strip 50 to advance by regulation step pitch automatically under die opening state, carries out continuous automatic press.
In the utility model, buoyance lift material lift part 31 connects entirety by washer 32 and locking member 33, with mandril 43, elastic element
42 and plug screw 41 form component bullet is passed through by lower die holder 10 and the location hole of lower template 20 11 and 21 stationary positioned of mounting hole
Property element 42 move up and down, up movement lift incoming band 50 away from lower template 20.
Due to such die life after 1.5 hundred million times or more, 3,000,000 jig frequency of lower die cutting edge punching press rust, need to integrally grind low
Ensure that cutting edge is sharp, the height that buoyance lift material lift part 31 is higher by the material lift section of lower template 20 becomes larger, in order to ensure that material strip 50 raises height
Spend almost the same, the needs of buoyance lift material lift part 31 facilitate adjustment height, and structure is changed to buoyance lift material lift part 31 by washer 32 and locking member
33 compositions, adjustment height are realized by grinding buoyance lift material lift part 31.It is loosened in the no locking of the presence of locking member 3 or punching course
May, buoyance lift material lift part 31 jumps back out in lower template 20, and upper mold pressure can explode mold when punching press, or even have part high speed and fly
Go out.
The utility model in 31 lower end of buoyance lift material lift part design hanging platform and position limiting structure 312, hanging platform design height by examining
Worry need to grind height, and lower template 20 designs countersunk head, and hanging platform and countersunk head stay the spaces 0.5~1mm, when soket head cap screw is fallen, buoyance lift
Material lift part 31 occurs due to there is hanging platform not jump out to prevent such major accident.
In the other embodiment of the utility model, soket head cap screw, buoyance lift material lift part 31 and washer 32 can also be cancelled
Design is integrated.This scheme can prevent to jump out problem, but height is unable to adjust, and 20 height of lower template needs brand-new different after being lower
Height part is replaced, and 20 requirement for height of general lower template reduces 8mm or so, to ensure material lift high consistency, at least
7 kinds of different heights need to be designed, cost and production management cost are increased.In the other embodiment of the utility model, it can also make
It obtains buoyance lift material lift part 31 and cancels hanging platform, connected by soket head cap screw.
It can be seen from the above description that the above embodiments of the present invention achieve the following technical effects：
Die assembly according to the present utility model can prevent such part and jump out cavity, avoid following situations；It breaks
Mold seriously affects the production schedule, and assembling stops line, influences delivery and meets with claim, the mold dimension of macrocyclic mold repair and great number
Expense is repaiied, part, which flies out, to cause casualties.Buoyance lift material lift part facilitates production maintenance height tune with locked component separate structure
It is whole.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
