Embodiment
A kind of punching stretch interchanged type mould, including upper die and lower die and the feeder between upper die and lower die, it is described
Upper mould includes the cope plate 1, backing plate 2, punch retainer 3 and the convex template 4 that are sequentially connected, and punch retainer 3 is connected with the side by side
A kerf drift 5, the second notch punches 6, draw punch 7, reforming plunger 8, pierce punch 9 and blanking die 10；The lower mould,
Concave template 12 including lower template 11 and above lower template, the concave template 12 has been mounted side by side and the first notch punches
5 corresponding first ejection blocks 13, with corresponding second ejection block 14 of the second notch punches 6, with draw punch 7 the corresponding 3rd push up
Expect block 15, the 4th ejection block 16 corresponding with reforming plunger 8, punching concave die insert 17 corresponding with pierce punch 8 and blanking punching
First 9 corresponding blanking die insert 18；And correcting die insert 19 is located at the top of the 4th ejection block 16, female die embedding is stretched
Block 21 is located at the top of the 3rd ejection block 15；The lower section of the blanking die insert 18 is blanking port 20.
Punching machine presses, convex template 4 is contacted with concave template 12, and concave template 12 makes the compression spring of convex template 4 with upward by fixation
Motion, ejects punch-pin, sheet material is pressed into cavity plate, the first ejection block 13 is moved downward.
The diameter of second notch punches 6 is more than the diameter of first notch punches 5, during second of otch, tie point with before
Connecting node mutually staggers.
Punching stretch interchanged type mould, its workflow is as follows：
Step 1, otch 1：
Material is sent in mould by feeder first, ensures that material will not during transport by helping material nail to be oriented to
Deflection.Punch press operating drives upper mould to run downwards simultaneously, when convex template touches concave template, and concave template is fixed and forces convex template
Compression spring is moved upwards, ejects punch-pin, and sheet material is pressed into cavity plate, and the first ejection block of cavity plate is moved downward.Now basis
The shape of punch-pin cuts sheet material, and retains a part of tie point, sheet material is not cut off, so as to reach the purpose of otch.Now
Mould is molded, and motion ejects sheet material to the first ejection block of cavity plate upwards, it is ensured that product is not snapped into cavity plate.
Step 2, otch 2：
Complete after first step otch, feeder operating feeding, punch press operating.The sheet material not being punched continues to complete the first step
Otch, while first step incision site is delivered under second step notch punches, now cope plate is moved downward, and forms of motion is same
Step 1, with step 1 difference, this second notch punches diameter is more than the diameter of the first notch punches, and tie point
Position is mutually staggered with connecting node before, does not result in the phenomenon of cut-out.
The step otch of the above two is primarily to the 3rd step stretches what is prepared, because metal plate can be sent out in stretching or bending process
The shape that changes or tear.In order to ensure the shape and outward appearance of product, deformation position is made in incision site by us, so that drawing process
In will not tear sheet material.
Step 3, stretch：
Complete the continuation feeding of step 2 feeder and the sheet material being punched is delivered into stretching station, now cope plate falls, stretching
Drift is stretched in sheet material press-in stretching die plate insert sheet material, incision site is dropped by punch-pin and inwardly deformed, shape
Into petal-shaped, so as to ensure that product edges are not stretched tear.Complete after drawing process, mold open passes through the 3rd ejection block
Product after stretching is ejected in order to avoid product is caught in concave template, and the punch-die of most importantly mould is fabricated to insert
Structure, the stretching diameter of product is changed by switching punch-die.
Step 4, shaping：
Complete the continuation feeding of step 3 feeder and the sheet material being punched is delivered into shaping station, mould closure.Reforming plunger will
In sheet material press-in stretching die plate insert, product shaping is carried out.Complete after reforming process, mold open, will by the 4th ejection block
Product ejection after stretching is in order to avoid product is stuck in concave template.This station mainly enters the product appearance and size after stretching
Row adjustment, makes it more accurate, it is adaptable to the higher product of precision.As fine, and the most importantly convex-concave molding of mould
The structure of insert is made, the stretching diameter of product is changed by switching punch-die.
Step 5, punching：
Complete feeder continuation feeding after step 4 and the sheet material being punched is delivered into punching station, mould closure.Pierce punch
The product stretched is pressed into punching concave die insert, product is punched out by circle by the offset of pierce punch and die plate insert
Hole, and the punch-die of most importantly mould is fabricated to the structure of insert, and the punching of product is changed by switching punch-die
Diameter.
Step 6, blanking：
Complete feeder continuation feeding after step 5 and the sheet material being punched is delivered into blanking station, mould closure.Blanking die
The product of active position is washed out, fallen into by blanking port in carrying case, the processing of product is completed.
It is described above, only the invention preferably embodiment, but the invention protection domain not
This is confined to, any one skilled in the art is in the technical scope that the invention is disclosed, according to the present invention
The technical scheme of creation and its inventive concept are subject to equivalent substitution or change, should all cover the invention protection domain it
It is interior.
