Illustrate the embodiment of the present invention now with reference to alterations.Those skilled in the art scholar is disclosed from this will
Clear, the explanation of following embodiment, which is only provided, makees exemplary explanation, rather than is to limit scope of the invention.
With reference first to Fig. 2 and Fig. 3, the continuous cutting die assembly of an embodiment according to the present invention is punched comprising first stop
Mold 10 and second station die cutting die 20.First stop die cutting die 10 includes the first die cutting die portion 11.First die cutting die portion
11 are equipped with stamping knife 11p, link oil hydraulic cylinder or pneumatic cylinder, to carry out the Punching Technology of first stage to plate 30.Second station punching
Cutting mold 20 includes the second die cutting die portion 21 and third die cutting die portion 22 being transversely spaced.Second die cutting die 21 and
Three die cutting dies 22, which are respectively equipped with, to be rushed block 21p and rushes block 22p, links oil hydraulic cylinder or pneumatic cylinder, in first stop die cutting die
The Punching Technology of second stage is carried out after 10 Punching Technology to plate 30.It is rushed by first stop die cutting die 10 and second station
Cut processing of the mold 20 at 30 same position of plate, the punching shape that can be synthesized at this.
Join Fig. 4, the stamping knife 11p in the first die cutting die portion 11 first generates two longitudinally spaced punching gaps to plate 30
11c1 and 11c2, then when the previous position being punched through first stop die cutting die 10 of plate 30 is delivered to second station punching
After mold 20, processing is punched out at the both ends of punching gap 11c1 and 11c2 again and generates the other punching being spaced laterally apart
Region 21c and 22c, whereby, punching gap 11c1 and 11c2 are connected with blanking area 21c and 22c and form synthesis punching shape
The outer profile of shape will fall as the intermediate materials 30m not being connected with plate 30 among this outer profile and be discarded.Knot
Fruit, this forms complete synthesis punching shape 30c (ginseng Fig. 7) on plate 30.Two punching gaps and at two of both ends
The size and location of blanking area are suitably arranged in pairs or groups to meet the outer profile of the synthesis punching shape to be reached.
It seem (such as servo motor, accurate belt, gear, refining item etc., be not shown), plate by positioning system of feeding of punching
30 can be delivered to second station die cutting die 20 from first stop die cutting die 10 to complete the accurate positioning of plate 30 and two stage
Blanking process.The skilled worker of this technical field is worked as and can be illustrated, is also possible to for second station die cutting die 20 being arranged
In the front of first stop die cutting die 10, the punching of two sides blanking area is first carried out, then carries out rushing for two punching gaps again
It cuts.
Referring again to Fig. 2, the first die cutting die portion 11 of first stop die cutting die 10 is vertically moving die cutting die,
It can adjust its height by using cushion block 12 to be padded below the pedestal in the first die cutting die portion 11, so that the first blanking die

The position adjustment in the first die cutting die portion 11, the second die cutting die portion 21 and third die cutting die portion 22 is not limited to
The mode stated, and can be reached with other mechanical, electronic, hydraulic mechanisms etc..
Referring to Fig. 5, the operation chart of first stop die cutting die 10 is shown, wherein Fig. 5 (A) is display stamping knife 11 and plate
The cross-sectional view that the line B-B in Fig. 3 of part 30 is taken, and Fig. 5 (B) is the top view for showing the plate through being punched.Carrying out the
When the Punching Technology in one die cutting die portion 11, stamping knife 11p is punched plate 30 twice, to form two punchings on plate 30
Joint-cutting gap 11c1 and 11c2.In this stage, the stamping knife 11p in the first die cutting die portion 11 first completes punching gap 11c1, then
Plate advances, and stamping knife 11p is completed and punching gap 11c2 again.The spacing being punched between gap 11c1 and 11c depends on plate
Forward travel distance.In other cases, the first die cutting die portion 11 can for example be equipped with two stamping knives of longitudinal subdivision, to be formed together
Above-mentioned two punching gap.
As seen in Figure 6, the stamping knife 11p in the first die cutting die portion 11 has gradient laterally outward, so that far from plate
There is gradually long lateral section (shape) on the direction of part 30.Preferably, stamping knife 11p is formed in substantive centre has given angle
The tip of degree.The angle at this tip is for example generally with 90 degree to 170 degree of range.It, can for biggish tip angle
There can be the length variation in apparent punching gap under the variation of lesser punching depth.For lesser tip angle,
Although can just there is the length variation in apparent punching gap under wanting biggish punching depth to change, smaller tip angle for
Plate can have bigger damage capability.
Since stamping knife 11p has gradually long effective section, when stamping knife 11p rushes deeper relative to plate 30, punching
The length of gap 11c1 and 11c2 become longer.In this embodiment, since the punching stroke in the first die cutting die portion 11 is solid
Fixed, the depth of punching is determined by the upright position in the first die cutting die portion 11.When the first die cutting die portion 11 is increased,
Punching depth is smaller, thus obtains shorter punching gap；When reducing the first die cutting die portion 11, punching depth is larger,
Thus obtain longer punching gap.However, in other cases, the first die cutting die portion 11 relative to the vertical of plate 30
Position is to be fixed, and punching stroke can be changed, so that forming the punching gap of different length.
In the processing procedure of C-type steel, the length that shape is commonly punched on plate is 75,89,100,120,140mm etc., can
The punching gap of these different lengths is formed using a stamping knife.For the commonly length 200 of longer punching shape, 250,
300, for 350mm etc., another stamping knife can be used to form these longer different lengths.In this way, need not prepare each
Kind size rushes block.
Next, showing the operation chart of second station die cutting die 20 referring to Fig. 7, wherein Fig. 7 (A) is display punching
The cross-sectional view that the line B-B in Fig. 3 of block and plate is taken, and Fig. 7 (B) is the top view for showing the plate through being punched.It is passing through
It crosses after first stop die cutting die 10, plate 30 is transported to second station die cutting die 20 to be punched out processing.Referring concurrently to
The block 21p and 22p that rush in Fig. 4 and Fig. 7, the second die cutting die portion 21 and third die cutting die portion 22 is punched out plate 30, with
Blanking area 21c and 22c are formed at the both ends of punching gap 11c1 and 11c2 on plate 30.Between blanking area 21c and 22c
