【Embodiment】
Illustrate embodiments of the invention now with reference to alterations.Will from this announcement for those skilled in the art scholar Clear, the explanation of following examples, 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, it is punched according to the continuous cutting die assembly of one embodiment of the invention comprising first stop Mould 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 provided with stamping knife 11p, and it links oil hydraulic cylinder or pneumatic cylinder, to carry out the Punching Technology of first stage to plate 30.Second station rushes Cut the second die cutting die portion 21 and the 3rd die cutting die portion 22 that mould 20 includes 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, and it links oil hydraulic cylinder or pneumatic cylinder, with first stop die cutting die The Punching Technology of second stage is carried out after 10 Punching Technology to plate 30.Rushed by first stop die cutting die 10 and second station Cut processing of the mould 20 at the same position of plate 30, the punching shape that can be synthesized in this place.
Join Fig. 4, the stamping knife 11p in the first die cutting die portion 11 first produces two longitudinally spaced punching gaps to plate 30 11c1 and 11c2, then when the previous of plate 30 is punched through the position that first stop die cutting die 10 is punched through being delivered to second station After mould 20, processing is punched out at punching gap 11c1 and 11c2 both ends again and produces 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 outline of shape, it will drop and discard as the intermediate materials 30m not being connected with plate 30 among this outline.Knot Fruit, this forms complete synthesis punching shape 30c (ginseng Fig. 7) on plate 30.Two punching gaps and two at both ends The size of blanking area and position are the outlines for synthesizing punching shape to be reached with meeting of suitably arranging in pairs or groups.
By positioning system of feeding of punching, seem (such as servo motor, accurate belt, gear, refining bar etc., be not shown), plate 30 second station die cutting die 20 can be delivered to from first stop die cutting die 10 with complete plate 30 be accurately positioned and it is two stage Blanking process.Work as and can understand for the skilled worker of this technical field, be also possible to set second station die cutting die 20 In the front of first stop die cutting die 10, the punching of both sides blanking area is first carried out, two is then carried out again and is punched rushing for gap Cut.
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 be by being padded on below the pedestal in the first die cutting die portion 11 to adjust its height using cushion block 12 so that the first blanking die The stamping knife 11p in tool portion 11 can be changed relative to the standing height of plate 30.Second die cutting die of second station die cutting die 20 Die cutting die portion 22 of portion 21 and the 3rd can transverse shifting on guide rail, to carry out the adjustment of lateral attitude, and by bolt or fixed Sell to fix position.
The position adjustment in the first die cutting die portion 11, the second die cutting die portion 21 and the 3rd die cutting die portion 22 is not limited to The mode stated, and mechanical, electronic, hydraulic mechanism etc. can be reached with other.
Reference picture 5, it shows the operation chart of first stop die cutting die 10, and wherein Fig. 5 (A) is display stamping knife 11 and plate The sectional view taken along the line B-B in Fig. 3 of part 30, and Fig. 5 (B) is the top view of plate of the display through punching.Carrying out the During the Punching Technology in one die cutting die portion 11, stamping knife 11p is punched twice to plate 30, 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 to be punched 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 provided with two stamping knives of longitudinal subdivision, to be formed together Above-mentioned two is punched gap.
As seen in Figure 6, the stamping knife 11p in the first die cutting die portion 11 has gradient laterally outward so that away from plate There is gradually long horizontal section (profile) on the direction of part 30.It is preferred that stamping knife 11p is formed in substantive centre has given angle The tip of degree.This sophisticated angle for example has 90 degree to 170 degree of scope generally., can for larger tip angle There can be the length change in obvious punching gap under the change of less punching depth.For less tip angle, Although a length change in obvious punching gap can just be had by wanting larger punching depth under changing, smaller tip angle for Plate can have bigger damage capability.
Because stamping knife 11p has gradually long effective section, when stamping knife 11p rushes deeper relative to plate 30, punching Gap 11c1 and 11c2 length become longer.In this embodiment, because 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 raised, Punching depth is smaller, thus obtains shorter punching gap;When the first die cutting die portion 11 is reduced, 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 of the punching shape commonly used on plate is 75,89,100,120,140mm etc., can The punching gap of these different lengths is formed using a stamping knife.Length 200 for conventional longer punching shape, 250, 300th, for 350mm etc., another stamping knife can be used to form these longer different lengths.Consequently, it is possible to it need not prepare each Kind size rushes block.
Next, reference picture 7, it shows the operation chart of second station die cutting die 20, and wherein Fig. 7 (A) rushes for display The sectional view taken along the line B-B in Fig. 3 of block and plate, and Fig. 7 (B) is the top view of plate of the display through punching.Passing through Cross 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 the 3rd die cutting die portion 22 is punched out to plate 30, with Blanking area 21c and 22c are formed at punching gap 11c1 and 11c2 both ends on plate 30.Between blanking area 21c and 22c Spacing adjusted by the lateral attitude in the second die cutting die portion 21 and the 3rd die cutting die 22.By first stop die cutting die 10 The punching gap 11c1 and 11c2 formed be connected with the blanking area 21c and 22c formed by second station die cutting die 20 and Complete synthesis punching shape 30c outline is formed on plate 30.Middle non-blanking area 30m no longer with the phase of plate 30 Even drop.
It will be appreciated that synthesis punching shape 30c is not necessarily final punching shape, that is, this continuous cutting mould The die cutting die of more multistation can be additionally comprised, to be punched to the synthesis on plate 30 around shape 30c or other are not punched area Domain is punched out.
According to the adjustment of the first stop die cutting die 10 of this embodiment and second station die cutting die 20, visual demand is formed Smaller or larger synthesis punching shape.The characteristics of these synthesis punching shapes is that the punching shape at both sides is substantially identical, And the punching length of center section difference.Therefore, the section of stamping knife and rush block section area summation be less than be intended to rush The area of shape is cut, and is punched shape to change, for single punching shape, this is avoided must be using complete in known technology Size is rushed the shortcomings that block, and for multiple punching shapes, also avoid must prepare and change various sizes rush block or mould The shortcomings that.Punching strength is also advantageously reduced using stamping knife.
In the second embodiment of the present invention (not shown), in contrast to first embodiment, in order to complete as first implements Synthesis punching shape in example, the blanking area at both ends can be first punched using second station die cutting die 20, then using first Die cutting die 10 stand to be punched two of centre punching gaps.The general technology personage of the art, which works as, can understand this details, Therefore repeat no more.
