Abstract

The invention belongs to roller plotting system of cold rolled section. It develops rapid automatic plotting roller mechanism drawing system according to the similarity and roller characteristic value of the large scale steel and isomorphic small steel shape. The invention sorts the roller according to geometric form and determines the characteristic value of the roller. It programs VC++ plotting program and size labeling program according to geometric form and characteristic value of arx format. When plotting roller mechanism picture, finding the program corresponding to the sort of roller, loading the program to Auto CAD plotting software, running the program in command line, inputting the corresponding plotting feather parameter and size labeling parameter, the roller standard mechanism picture would be automatically drawn rapidly.

Description

Roller fast automatic drawing system

Technical field:

The invention belongs to the roller fast automatic drawing system of cold-rolled section, be the system that draws machine drawing according to the roll characteristic parameter that section design method is designed fast automaticly.

Background technology:

Cold-rolled forming section or longitudinal welded pipe are cold rolling section bars commonly used in the development of the national economy, and the instrument of rolling cold-rolled forming section or longitudinal welded pipe is a roll.The moulding of cold-rolled forming section or longitudinal welded pipe will be by the last moulding of the crimp of many roll stacks.Every roll stacks constitutes this pass, after pass designs, according to calculating, obtains forming each roller parameter of pass, draws the mechanical drawing of each roll at last.Because the geometric configuration of roll is very complicated, the mapping software that promptly uses a computer, drawing drawing also can be very loaded down with trivial details.According to the situation of present professional production roll enterprise, a slip-stick artist only can draw several limited roll figure a working day, and this has directly influenced design and production cycle.The present invention develops the system of fast automatic drafting roll machine drawing according to characteristics such as the similarity of the corresponding roll of the small-sized steel of big shaped steel and similar shape and roll eigenwerts.

Summary of the invention:

The purpose of this invention is to provide a kind of fast automatic drafting roll machinery drawing system.It can be according to composing the machine drawing that the characteristic parameter of giving each roll is drawn standard apace in the pass design.As long as the basic configuration of selected roll and concrete parameter, native system can be finished drawing work fast, has surpassed people's plotting speed out and away.

In order to realize above-mentioned purpose of the present invention, the scheme that the present invention takes is:

1. the selection of shape

For some general cold-rolled forming section or longitudinal welded pipe, its roll geometric shape has similarity, only is the difference of size.The present invention is with roll divide into several classes shape.For the roll of certain type, the input design parameter is big, then obtains big roll, the big shaped steel of rolling similar shape, and the input design parameter is little, then obtains little roll, the little shaped steel of rolling similar shape.

2. rolling eigenwert chooses

The shape of roll is according to the requirement of pass and fixed.In order both to satisfy the Roller Machining requirement, reduce the purpose of redundant data again, native system is selected the eigenwert of important data as roll for use, can ignore for inoperative some data of breaker roll.Because the pass of each frame is different, the shape of roll is also different, and what of roll eigenwert number are also inconsistent.But the eigenwert of determining must be to make the roll necessary parameter.

3. program drawing

3.1 object ARX software is installed in the VC++ development environment;

3.2 establishment eigenwert loading routine, module plotter program and mark parameter loading routine etc., being made into .arx is the file of extension name;

3.3 in AutoCAD, load plotter program, and in AutoCAD, move the module plotter program;

3.4 under prompting, import relevant parameters, can go out the roll machine drawing rapidly after satisfied.

Description of drawings: Fig. 1 is a roller fast automatic drawing system synoptic diagram of the present invention.1 is that the VC++ development environment loads the ARX interface among Fig. 1, the 2nd, the plotter program of all types of rolls of establishment, the 3rd, a plurality of parameter inputs and plotter program, the 4th, in the AutoCAD mapping software, load the roll plotter program, the 5th, operation roll plotter program is drawn in the AutoCAD mapping software.

Embodiment:

At first selecting the proportional roll of eigenwert according to the pass of rolling section bar is similar roll.Classification according to said method, and the number of parameters of definite this type of roll.ARX software is installed in the VC++ environment, sets up plotter program and the parameter marking program of ObjectARX AppWizard.Plotter program of every class roll establishment gets final product.Start AutoCAD, will expand arx program by name then and be loaded in the AutoCAD environment.And in the AutoCAD command bar operation this program.After the input parameter title input of program prompts relevant eigenwert and mark parameter, plotter program will be drawn corresponding roll figure automatically in AutoCAD.The machine drawing that plotter program is drawn can directly be revised in AutoCAD.

The present invention compared with prior art, its advantage is: according to the similar figures characteristics of shaped steel, adopted roll similar figures sorting technique and roll eigenwert technology, and two technology are carried out the drawing and the marking program design of roll in view of the above.When startup drawing and marking program under AutoCAD and after importing corresponding Roller Design parameter and marking parameter, AutoCAD draws corresponding roll machine drawing apace, significantly improves drawing efficiency.

Claims

1, roller fast automatic drawing system carries out the system of QuickDraw to cold-rolled forming section and the rolling roll of longitudinal welded pipe.The roller parameter that designs in the pass is input in the native system corresponding module, and native system will be drawn corresponding roll figure automatically.

2, roller fast automatic drawing system according to claim 1 is classified by geometric configuration to general roll, it is characterized in that: same class roll geometric configuration has similarity.Be that same class roll has a fixing geometric shape, the size of input roll eigenwert only determines roll to amplify in proportion or dwindles, but the overall geometry form remains unchanged.Such as: certain roll of rolling diameter of phi 50mm pipe is similar with the corresponding roll geometric shape of rolling diameter of phi 76mm pipe, the physical dimension difference.

3, roller fast automatic drawing system according to claim 2 is determined the eigenwert number of same class roll.It is characterized in that: same class roll has identical eigenwert number.The eigenwert number what by the decision that needs of drawing.Promptly can satisfy the machining precision of roll, can not increase redundant data again.

4, roller fast automatic drawing system according to claim 3, the drawing characteristic ginseng value of same class roll can be different, but proportional substantially.The essential characteristic value number of drawing roll should be consistent.

5, roller fast automatic drawing system according to claim 1 is drawn and has been adopted VC++ and ARX interface software.It is characterized in that: work out corresponding roll machinery plotter program and marking program with VC++ language, class libraries etc. with the ARX interface software, these programs are to be the file of extension name with arx.

6, roller fast automatic drawing system according to claim 5, the mapping software that is loaded into AutoCAD directly draws.It is characterized in that: move the value-added tax function among the AutoCAD earlier, the plotting file that will be extension name with arx is loaded among the AutoCAD, in the order line of AutoCAD, move plotting file, behind prompting input parameter title symbol, provide relevant parameters, can go out to have the roll machine drawing of mark after satisfying.These figure can directly revise in the mapping software of AutoCAD.
