Description

Progressive forming processing method and device
Technical field
The present invention relates to progressive forming processing method and device.
Technical background
On one side bar-shaped instrument and metallic plate raw material are bumped and connect, one side with answer the formed article shape corresponding, along contour in addition the progressive forming process equipment of progressive forming in following patent documentation 1, come forth.
[patent documentation 1]
The spy opens 2002-1444 communique (european patent application discloses 1147832A2 number)
Summary of the invention
Fig. 1 uses the oblique view of the present invention by the goods of progressive forming processing and fabricating.
Represent that with symbol 1 whole goods are to possess the outstanding structure of the 2nd shaped portion 20 that middle body at the 1st shaped portion 10 with the crooked section configuration of two dimension has 3D shape.
Fig. 5～Fig. 9 represents the operation with common progressive forming processing and fabricating goods 1.
The anchor clamps 100 that are provided in the shaping usefulness on the workbench 50 have 1st type member 110 corresponding with the 1st shaped portion 10 of goods and the 2nd type member 120 corresponding with the 2nd shaped portion 20 of goods.
Metallic plate 140 as processing (raw material) is raw material of flat shape, and its periphery is by work holder 130 and 150 clampings of workpiece clamping plate.Work holder 130 can descend from the top of the 2nd type member.Progressive forming machining tool 160 makes the axle center can move with vertical direction in the horizontal direction along vertical direction.
Fig. 6 represents that the summary of processing one by one, Fig. 7 represent the route that is shaped.
As Fig. 6, as shown in Figure 7, be applied on the whole work-piece by making route P1 that the 1st shaped portion is shaped and the route P2 that the 2nd shaped portion is shaped, and be processed into shape of products.
As shown in Figure 8, progressive forming machining tool 160 flat shape 140 above one side on parallel X-Y axle, move, on one side form at a Z-direction pitch of feed P.In each figure of Fig. 8, show progressive forming machining tool 160, be actually 1.Represent to move with 3 instruments 160 along contour.
That is,, be shaped so and will advance along contour if the spacing P of feeding is defined as constant.When the radius of curvature of the 1st shaped portion curved surface was big, the interval of the route of adjacency broadened, and produced the problem of formability variation.
Therefore, improve formability, will increase the total length of shaping route so, elongated improper situation process time occurs if want to reduce pitch of feed.
Fig. 9 (a) expression progressive forming process finishing, the 1st shaped portion 10 and the processed state of the 2nd shaped portion 20 on workpiece 140.
Then, corresponding with the peripheral shape of goods, on workpiece 140, implement suitable trim process C1, obtain goods 1.
On workpiece 140, remaining have the end face material (offal) that cuts out the space 142 of goods by trim process, becomes the reason that makes raw-material decrease in yield.
The present invention just provides progressive forming processing method and the device that solves the above problems.
For achieving the above object, 3 dimension shape progressive forming methods of the present invention are exactly the workpiece of preparing to have the curved surface corresponding with the 1st shaped portion, in the part of this workpiece the 2nd shaped portion of 3 dimension shapes are processed.
And, the progressive forming processing unit (plant) possesses the work holder of placement holding workpiece periphery and the workbench of workpiece clamping plate, and the progressive forming machining tool that is mounted at vertical direction of principal axis for workbench, and possess work holder corresponding and clamping plate with processing curve.

The specific embodiment
Fig. 2～Fig. 4 is the key diagram of preparation method of the goods of expression progressive forming of the present invention processing.
In the present invention, 200 of forming jigs that are provided on the workbench 50 possess the type model component 220 corresponding with the 2nd shaped portion of goods.
Be processed to have the curved surface of the 2 dimension curved surfaces identical in advance with the 1st shaped portion of goods as the metallic plate 240 of workpiece (raw material).
Work holder 230 has the seat surface consistent with the curved surface of workpiece 240 232.Also identical with workpiece clamping plate 250, have the clamping plate face 252 consistent with the curved surface of workpiece 240.
Adding man-hour, progressive forming machining tool 260 and workbench are relatively moved along the flat shape of the 2nd shaped portion on X-Y plane, simultaneously, when at progressive forming machining tool 260 when Y direction relatively moves, control so that make progressive forming machining tool 260 along the 1st shaped portion, promptly the curved surface along workpiece 240 moves.
In addition,, make the spacing P2 of 260 feeding regulations of progressive forming machining tool, the 2nd shaped portion is processed identical with the processing of common progressive forming along with the carrying out of processing.
As shown in Figure 4, because pay 2 dimension curved surfaces in advance for workpiece 240, and only 3 dimensions the 2nd shaped portion is carried out progressive forming processing, so the shaping route can shorten, and also be shortened process time.

Claims (4)
