There is many Ban gold part in mechanical spare parts, undertake well and truly designing is in to its and its mould contemporary below production demand, become more and more important. Discussed the process that uses general CAD/CAM software to undertake designing to Ban gold spare parts and its mould and method, raise efficiency and accuracy with this, also laid a foundation for CNC Machining at the same time. Spare parts of gold of the Ban in foreword machinery spare parts is having very large amount, and undertake well and truly designing to its and its mould, be in contemporary below production demand, become more and more important. Software of current and commonly used a few CAD/CAM also reached his to promote accurate and efficient and convenient, sudden shift to the design that presses a mould for Ban gold spare parts. The article is with Pro/ENGINEER exemple, the Ban gold part that treated punch to shape and its mould have the process of the design and method. Graph 1 to design flow chart, graph the 2 Ban gold part drawing that devise example for. 1 design stage (the design construction that the geometry that 1) uses according to the spare parts above all, mechanical function and the requirement such as production condition decide a part and workmanship. (2) if the spare parts is bend, strong reduce a construction, the " part that can use Pro/E directly - module of Ban gold " completes hardware design; If the spare parts is drawing structure (2) seeing a picture, the " part that can use Pro/E first - the sunken model that design of hypostatic " module gives drawing pattern (with or punch) , the " spare parts of reoccupy Pro/E - the basic structure that design of module of Ban gold " gives a part, graph 2 spare partses design a circle board first, use " to shape next (FORM)" command, shape drawing sunken model appearance of the structure duplicates in the spare parts. (3) completes the design of structure of spare parts other, if pursue an edge of 2 spare partses. (4) is finished develop a plan. (The 5) drawing that finish, strong cut into parts and bend or the design that other place requires a mould. Graph 1 design flow chart 2 drawing part drawing 2 designs method 2.

Protruding of 1 drawing structure / the " part that the design of sunken model uses Pro/E - hypostatic " module: [Build hypostatic Solid] of Part]-[of New]/[spare parts, build protruding / file of sunken model graph, application commands the design that finish accordingly, graph the 3 sunken patterns that show a part 2 times for the graph. Graph 3 drawing sunken model 2.

The " part that design of hardware of 2 Ban gold uses Pro/E - module of Ban gold " : [Build Sheetmetal] of gold of Ban of Part]-[of New]/[spare parts, build Ban gold part graphical file, application commands the design that finish accordingly. Among them drawing structure must shape with " Form" command is finished, with making this structure can shape with " level off Flatten Form" command develops plane. 2.

3 develop a plan 2.

Can the 1 spare parts that does not have drawing structure use " to spread out the command: such as Unbend" ? Entree of languid  Art is odd - [diagnostic Feature]/[founds Sheetmetal]-[of Creat]-[Ban gold to exhibit smooth Unbeng] , launch the part. 2.

The spare parts ground that 2 have drawing structure spare parts the position of each structure, shape ordinal, OK and ordinal use " level off to shape the structure that Flatten Form" command develops to shape with mould drawing, use " to exhibit the command such as smooth Unbend" to spread out curve generated structure. Use " level off to shape when Flatten Form" command develops the structure that shapes with mould drawing, its are generated spread out appearance and size are umbriferous formation appearance and dimension, actually drawing shapes the figure with spare parts bad wool and dimension are the area computation after shaping according to the spare parts comes out, because this needs according to shape the area after spare parts computation spreads out. The measurement that uses Pro/E software itself does the surface that can the function go to the lavatory to get a part well and truly accumulate: ? Say ダ Fu Analysis]/[Measure] , shoot a Measure dialog box, proper option is installed in this dialog box, choose the surface that should measure, the surface that can acquire a part is accumulated. Also can use spare parts surface to duplicate curved surface of a neutral line (Surface) , the area type in using frame of Measure Liu word (Type): ? Biao Zuo Rea and definition (is Definition)- hypostatic (Entity): ? Option of Xi Xin?Quilt) , apace measures area of spare parts neutral line. According to the measured value of this area, can the size that apace determines spare parts wool is bad. Usually, after drawing shapes, workpiece mouth ministry or protruding edge periphery are not orderly, need undertakes decorating a border, in order to achieve the design requirement of the spare parts. Accordingly, when the dimension of computational part semifinished product, must add H of Δ of the surplus that decorate a border, if pursue the A=36538 of area of neutral line surface of spare parts of 2 body that show a bowl.

3mm2, reach shape partial wool bad diameter 215.

69, decide according to the appearance of the spare parts and dimension the surplus that decorate a border is 2mm, diameter of so final semifinished product: H=219 of D=d+2 × Δ .

The move that 69mm3 conclusion describes according to above place and method, the " part that uses Pro/Engineer software - Ban gold " and " spare parts - the function building a model of hypostatic " module, spare parts of combinative Ban gold and the specific requirement that its mould designs, of the design that can complete Ban gold spare parts and its mould well and truly quickly and part semifinished product spread out, this software " analyses recycle / measure the function such as " , can calculate those who give part semifinished product to develop measure conveniently. This kind of method applies to the design of spare parts of gold of of all kinds Ban and its mould, versatility is strong, go easily simply. And, of program of the numerical control when the part that with Pro/ENGINEER the design gives and mould model also can be used at numerical control machine tool to machine generate. CNC Milling
