Abstract
The invention discloses a sheet metal part three-dimensional die set design technology. The sheet metal part three-dimensional die set design technology comprises the first step of starting modeling software and extracting information of surfaces of a target sheet metal part, the second step of building a new template and extracting the geometrical characteristic of the sheet metal part, the third step of drawing a two-dimensional picture with the part surfaces as working planes, the fourth step of carrying out extrapolation extending on the surfaces of the extracted sheet metal part, the fifth step of dividing a stretching body in the third step, the sixth step of trepanning a dividing body at the pin hole position and trepanning positioning holes in the edge portion of the dividing body, the seventh step of carrying out the circular bead process on the dividing body to finish the design of a die tire, and the eighth step of repeating the seven steps with the designed die tire as the standard to design other parts of the component. The method can improve the machining precision of the sheet metal and can adapt to the technological tendency from a two-dimensional model to a three-dimensional model.
Description
Technical field
The invention belongs to Computer-aided Design Technology field, relate in particular to the three-dimensional press-moulding die design technology of a kind of sheet metal component.
Background technology
The Thin-shell constitutional detail that sheet metal component is made up of metal blank, is widely used in all trades and professions.Mould is to utilize the given shape of itself to go shaping to have the goods instrument of definite shape and size.It is one of important basic equipment in commercial production.Along with IT application in enterprises with manufacture and design the development that deepens continuously of digitizing technique, design, the processing of sheet metal part are also being carried out deep reform.The mode of traditional two-dimentional universal mold design can not meet the needs of modern Aviation production.
First Three-Dimensional Modeling Technology can carry out solid modelling to sheet metal part.Sheet metal component solid modelling is mainly carried out in sheet metal designing module, will indicate the relevant information of sheet metal component in design process.Such as having or not the correlated characteristics such as symmetrical member, sheet metal component parameter, modeling benchmark, technique information, assembling figure number, contour dimension, the dated standard that Design of Dies personnel has been played to certain reference of these features.
Summary of the invention
Technical matters to be solved by this invention is: comply with Tool and Die Technology development trend, a kind of process that relates to of three-dimensional model is provided.
The technical solution used in the present invention is:
The three-dimensional press-moulding die design technology of a kind of sheet metal component, comprises the following steps:
1. start modeling software, extract each surface of target sheet metal part, sheet metal part surface and the pin hole position of extracting are copied;
2. a newly-built part template, concentrates the sheet metal part surface of extraction and pin hole position to paste at newly-built part template geometric figure, completes the extraction to sheet metal part geometric properties;
3. taking extract piece surface as working face carries out two-dimensional pattern drafting, subsequently drawn figure is stretched, draw direction is identical with the direction of sheet metal component bending;
4. extrapolation extension is carried out respectively in the panel beating surface of extracting, till making the surface of extrapolation be large enough to cut apart the extrusion in three steps;
5. the extrusion in 3. step is cut apart;
6. in pin hole position, dividing body is carried out to perforate, position hole perforate in dividing body marginal portion subsequently;
7. dividing body is carried out to fillet processing, complete the design to mould tire;
8. taking the mould tire of previous designs as benchmark, repeat 1-7 step, other ingredients of design part.
Preferred scheme is that described modeling software is CATIA software.
The present invention can effectively overcome curved surface on three-dimensional modeling and the technical barrier such as cut apart, and improves the precision of modeling, the technological trend of adaptive model from two dimension to three-dimensional model.
Embodiment

Start the three-dimensional sheet metal designing software module of CATIA, design a kind of three-dimensional model of coverplate parts, step specific as follows:
1. extract each surface of target sheet metal part, sheet metal part surface and the pin hole position of extracting are copied;
2. a newly-built part template, concentrates the sheet metal part surface of extraction and pin hole position to paste at newly-built part template geometric figure, completes the extraction to sheet metal part geometric properties;
3. taking extract piece surface as working face carries out two-dimensional pattern drafting, subsequently drawn figure is stretched, draw direction is identical with the direction of sheet metal component bending;
4. extrapolation extension is carried out respectively in the panel beating surface of extracting, till making the surface of extrapolation be large enough to cut apart the extrusion in three steps;
5. the extrusion in 3. step is cut apart;
6. in pin hole position, dividing body is carried out to perforate, position hole perforate in dividing body marginal portion subsequently;
7. dividing body is carried out to fillet processing, complete the design to mould tire;
Above-described embodiment is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
