Abstract
The invention is a digital controlled gradually-shaping method able to quickly shape metal sheet without mould, using ball head tool as shaping one, using clamps to fix the sheet on the working table of digital controlled machine tool, using 3D software to control the ball head tool and the working table to relatively move according to NC code produced by the product shape, using the ball head tool to gradually extrude part of the sheet to distort the sheet so as to gradually approach to the product shape size, and finally obtaining the finished product. It replaces the molding surface of the mould with the envelope surface formed by tool moving track to gradually shape parts.
Description
Technical field
The present invention relates to the manufacturing process and the building mortion thereof of sheet metal, a kind of specifically numerical control progressive forming method and device thereof that utilizes plastic deformation to realize the sheet metal quick shaping.
Background technology
Conventional metal sheet forming technology realizes by mould.This method working (machining) efficiency height, constant product quality, low cost product during production in enormous quantities.But adopt this method Mould design, manufacturing and debugging cycle longer, die cost is higher, is not suitable for the innovative design and the short run processing of product.Along with improving constantly of people's living standard, society is to the requirement variation day by day of product, and the life cycle of product shortens, and the renewal of product is accelerated, and this constantly brings forth new ideas with regard to the design that requires product, requires the many kinds of production, the small batch of product.This shows that conventional metal sheet forming technology can not satisfy this class demand in market.
Summary of the invention
In order to remedy the deficiency of common metal sheet material forming technology, the invention provides a kind of sheet metal numerical control progressive forming method and device thereof, need not to use mould can be needed product with the sheet metal progressive forming just.
The numerical control progressive forming method of sheet metal of the present invention, be to use the bulb instrument as forming tool, to be fixed on the worktable of numerically-controlled machine with anchor clamps around the sheet metal, utilize three-dimensional software to do relative motion according to NC code control bulb instrument and the worktable that product design generates, the bulb instrument pushes one by one to the sheet material part, the physical dimension that makes the sheet material plastic yield approach product one by one, making sheet material forming is required product.
The present invention realizes that the sheet metal numerical control progressive forming device that described method is used is made of numerically-controlled machine, anchor clamps, forming tool and support stick, anchor clamps are installed on the worktable of numerically-controlled machine, forming tool is installed in the cutter fixed head of lathe, support stick is fixed on the bed piece, and described forming tool is the bulb instrument.
Aspect hardware unit, use the bulb instrument as forming tool, will be fixed on the worktable of numerically-controlled machine with anchor clamps around the sheet metal, and reserve enough deformation spaces in the sheet material bottom.Support stick is installed on lathe is used to support the sheet material bottom, strengthen the rigidity of sheet material, prevent sheet material unstability in process.
On technology path, at first in three-dimensional software, set up the spatial shape of plate product, according to product design the reasonable process technology parameter is set, generate machining path, utilize the preprocessor that software provides to generate the NC code then, these codes are input to that control bulb instrument and worktable do relative motion in the lathe again, the bulb instrument pushes one by one to the sheet material part, the physical dimension that makes the sheet material plastic yield approach product one by one, finally making sheet material forming is required product.
This method replaces the profile of mould to come the progressive forming part with the formed enveloping surface of the relative movement orbit of worktable and instrument, therefore need not at first to design and mfg. moulding die.
Meaning of the present invention is, need not design and mfg. moulding die and just can process needed sheet metal product, thereby shortened the manufacturing cycle of product, has reduced processing cost, is particularly suitable for the trial-production or the short run processing at product development initial stage.

1. worktable, 2. anchor clamps, 3. bulb instruments, 4. sheet metals, 5. support sticks among the figure.
Embodiment
In Fig. 1, the present invention realizes that the step of sheet metal quick shaping is: the spatial shape that at first makes up plate product in three-dimensional software, appearance profile according to product is provided with optimum technological parameter then, generate machining path, utilize machining simulation functional check machining path setting that software provides whether rationally or inerrancy arranged, the preprocessor that utilizes software to provide after the affirmation generates the NC code that numerically-controlled machine can be discerned, again these NC codes are called in numerically-controlled machine, drive numerically-controlled machine worktable and bulb instrument do relative motion, the bulb instrument pushes one by one to the sheet material part, the physical dimension that makes the sheet material plastic yield approach product one by one, finally making sheet material forming is required product.
In device work synoptic diagram shown in Figure 2, anchor clamps (2) are fixed on sheet material (4) on the worktable (1), by the relative motion of worktable (1) and bulb instrument (3) sheet material are carried out plastic yield one by one, finally are configured as required product.In the progressive forming process, bulb instrument (3) has an extruding force to sheet material, and is very big as the surface configuration fluctuating of fruit product, just causes the sheet material unstability easily, and therefore the form accuracy of product can not get guaranteeing.Native system prevents sheet material unstability in the progressive forming process by adding the rigidity that a support stick (5) strengthens sheet material in the sheet material bottom.Add and regulate the position of support stick (5) according to the shape of product needs man-hour, lock it on the lathe then and bulb instrument (3) pairing is used.
Claims (2)
1, a kind of numerical control progressive forming method of sheet metal, it is characterized in that: use the bulb instrument as forming tool, to be fixed on the worktable of numerically-controlled machine with anchor clamps around the sheet metal, utilize three-dimensional software to do relative motion according to NC code control bulb instrument and the worktable that product design generates, the bulb instrument pushes one by one to the sheet material part, the physical dimension that makes the sheet material plastic yield approach product one by one, making sheet material forming is required product.
2, realize the sheet metal numerical control progressive forming device that the described method of claim 1 is used, it is characterized in that constituting by numerically-controlled machine, anchor clamps, forming tool and support stick, anchor clamps are installed on the worktable of numerically-controlled machine, forming tool is installed in the cutter fixed head of lathe, support stick is fixed on the bed piece, and described forming tool is the bulb instrument.
