Abstract
The invention relates to a method for changing die shape when overall dimension of a forming die or sample die changes. The method comprises the following steps: cutting a die body into two die bodies on a working face of the die according to the die shape, and then adding a die supplement which has the same material as the die bodies and the corresponding shape at the cutting place of the die, or removing the excess die body at the cutting place, connecting and fixing the die supplement and the two cutting die bodies of the die with locating pins and fitting bolts on a non-working face, and then remachining the die. In the invention, a method of increasing or decreasing the die bodies on the working face of the die is employed to cause the die to be applied to the forming die and modification of plane and automobile components at research and development stage of planes and automobiles, thus decreasing quantity of new dies.
Description
Technical field
The present invention relates to a kind of to shaping mould or sample-piece mold a kind of method that changes die shape when appearance and size changes.
Background technology
In aircraft, automobile development process, run into the situation that certain parts need be adjusted through regular meeting, and the adjustment of each parts just generally can cause the part change; The part change just can produce the change of the frock of finished parts again.Change has two kinds of situations as part, and wherein a kind of is the part reduced profile, and another kind of situation is that the part profile strengthens.Change little situation for the part profile, general manufacturing frock generally is recoverable by reprocessing in processing, and situation about strengthening for the external form of part, generally be not easy to reprocess, if the external form of part is complicated, and what make this part is metal die, normally this metal die is scrapped again and is made.Scrap the new system frock and can produce two kinds of main negative consequences, 1 increases the frock manufacturing cost; 2 prolong the frock manufacturing cycle, can directly influence the progress of producing, and serious situation can have influence on the payment on time of products such as aircraft, automobile.
Summary of the invention
The objective of the invention is to provide a kind of mould changes the problem of scrapping because of profile a kind of method that changes die shape that solves.Technical solution of the present invention is, according to mold shape the mold cutting of mould is divided into two molds on die-face, then, adopts one of following mode,
(1) at mold material identical, the shape corresponding mould added body of the cut place of mould increase with mould, with mould added body and two molds that are cut mould after being connected and fixed with alignment pin and bolt on the non-working surface, processing mold profile again;
(2) remove unnecessary mold in the cut place of mould, with two molds being cut mould after being connected and fixed with alignment pin and bolt on the non-working surface, processing mold profile again.
Cutting position on die-face is chosen in die-face straightway position or near the center of straightway position or working face.
Advantage that the present invention has and beneficial effect, the present invention adopts the mode that increases or reduce mold on the working face of mould, make mould can be applicable to the development stage of mould at aircraft and automobile, the remodeling of aircraft, auto parts, reduced the new system quantity of mould, can reduce the phenomenon of scrapping of mould with this repair method, reduce development cost, especially in the reprocessing of the relatively large import mould of automobile, be suitable for especially.

Fig. 2 connects die body surface, back and detects schematic diagram with model for Fig. 1 mould decomposes;
Fig. 3 connects generalized section for Fig. 1 die body.
The specific embodiment
On die-face, the cutting of the mold of mould is divided into two molds, then, adopts one of following mode according to mold shape,
(1) at mold material identical, the shape corresponding mould added body of the cut place of mould increase with mould, with mould added body and two molds that are cut mould after being connected and fixed with alignment pin and bolt and fixed head on the non-working surface, processing mold profile again;
(2) remove unnecessary mold in the cut place of mould, with two molds being cut mould after being connected and fixed with alignment pin and bolt on the non-working surface, processing mold profile again.
Cutting position on die-face is chosen in die-face straightway position or near the center of straightway position or working face.
Embodiment one
The method that die shape strengthens, its main technique measure is to adopt molybdenum filament electric spark cutting die, promptly on the more suitable surface of die body body, with the molybdenum filament electric spark mold is cut into mold 1 and mold 3, then, increase and the concrete identical mould added body 2 of grand master pattern in the cut place of mold, after mould added body 2 that increases and the mold 1 after the cutting and mold 3 usefulness alignment pins 4 bolts 5 location-plates 6 are connected and fixed, Mathematical Modeling according to the required standard of mould, with Digit Control Machine Tool processing mold profile again, perhaps according to the original profile of mould, directly with mould added body 2 that artificial fairing increased, perhaps manually reprocess by mold 1 with standard jig 7, the profile of the new die 8 of mold 3 and mould added body 2 stack combinations makes the requirement up to specification of die body monnolithic case.See Fig. 2 for details.
Embodiment two
The method that die shape reduces, its main technique measure is the more suitable surface at mold, mold is cut into mold 1 and mold 3, on mold 1 and 3, cut respectively again and remove the mold part that mould should reduce, after more remaining mold 1 and mold 3 usefulness alignment pins 4 bolts 5 being connected and fixed, Mathematical Modeling according to the required standard of mould, with Digit Control Machine Tool processing mold profile again, perhaps according to the original profile of mould, directly with mould added body 2 that artificial fairing increased, perhaps manually reprocess by mold 1 with standard jig 7, the profile of the new die 8 of mold 3 and mould added body 2 stack combinations makes the requirement up to specification of die body monnolithic case.
Claims (2)
1. a method that changes die shape is characterized in that, according to mold shape the cutting of the mold of mould is divided into two molds on die-face, then, adopts one of following mode,
(1) at mold material identical, the shape corresponding mould added body of the cut place of mould increase with mould, with mould added body and two molds that are cut mould after being connected and fixed with alignment pin and bolt on the non-working surface, processing mold profile again;
(2) remove unnecessary mold in the cut place of mould, with two molds being cut mould on non-working surface, after being connected and fixed with alignment pin and bolt and fixed head, processing mold profile again.
2. the method that die shape according to claim 1 strengthens is characterized in that, the cutting position on die-face is chosen in die-face straightway position or near the center of straightway position or working face.
