Abstract
The invention relates to a method for assembling an automobile covering part drawing die based on a knowledge-based engineering (KBE) system, belongs to the field of design and manufacture of automobile covering part dies, and solves the technical problem that assembly efficiency is reduced because the conventional model is low in utilization rate. The method comprises the following steps of: 1, preliminarily determining parts, components and an assembly route which are required by die assembly; 2, determining an assembly reference part; 3, adding part assembly features, a constraint relation and an assembly reference; 4, establishing an assembly model of the components of the automobile covering part drawing die; 5, measuring and adjusting a gap between a male die and a female die, performing interference detection on actions such as guiding, discharging and pushing, and designing and correcting the model; 6, assembling the model of the components; and 7, assembling the die. The organization form and method of die assembly are reasonably selected, the assembly quality of the die can be ensured, the assembly efficiency is improved, and the labor intensity of workers is reduced.
Description
Technical field
The present invention relates to the automobile die assembly method, is a kind of automobile panel cupping tool assembly method of KBE, belongs to Auto body panel die design and manufacturing field.
Background technology
Whether the prosperity of auto industry is the important symbol of estimating the Industry Development Levels such as country's machinery, electronics, material, mould.Body of a motor car mainly is comprised of automobile panel, and its design and production are the keys of car load exploitation, and it has determined construction cycle and the cost of new model to a great extent.China's automobile volume of production and marketing in 2011 continues to be sure to occupy the whole world the first, being in great demand of car panel die.The assembly quality of drawing and forming mould directly affects stamping quality and mold use and the maintenance of covering in the car panel die production process, and the assembling level that therefore improves such mould is the key that promotes automobile industry development.
Car panel die weight can reach tens tons, and the position that the assembling of each parts need to be adjusted is more, and assembly period, long-acting rate was low, and the quality of die assembly depends on assembler's experience.A lot of standard components are the position difference when having assembling in the assembling process, and model is identical, and more time assembling standard component or a series of standard component of cost will repeat modeling when product carried out trim designs, and the utilization rate of model is not high, causes efficiency of assembling to descend.
Summary of the invention
The utilization rate that the present invention will solve existing model is not high, the technical problem that causes efficiency of assembling to descend; And a kind of automobile panel cupping tool assembly method based on assembly features simulation is provided.The present invention is in conjunction with KBE (Knowledge-based Engineering, be called for short KBE, i.e. knowledge engineering) technology, the organizational form of choose reasonable die assembly and method, can guarantee mould assembly quality, improve efficiency of assembling, alleviate workman's labour intensity.
Automobile panel cupping tool assembly method based on the KBE system among the present invention realizes by following step:
Step 1, analysis car panel die fittage are tentatively determined required parts, assembly and the assembling route of die assembly;
Step 2, according to step 1 die assembly task analysis result, set up the cupping tool Standardized part model library of KBE, cupping tool Standardized part model library comprises the standard of part geometry model library and assembling, and determines the standard of assembling according to major part processing and structural dependence;
Step 3, obtain standard according to step 2, add parts assembly features, restriction relation and reference for assembling;
Step 4, each Assembly of the parts of determining according to step 3 concern that other parts are take reference for assembling spare as the basis, and rule-based reasoning is assembled, and sets up each component assembling model of automobile panel cupping tool;
Step 5, according to the component assembling model that step 4 obtains, measure the interference of adjusting clearance between punch and die and guiding, discharging and push piece action and detect, this model is designed and revises;
Step 6, according to the assembling model that step 5 obtains, finish each component assembling model;
Step 7, the die assembly Model Mounting that obtains according to step 6 go out actual automobile panel cupping tool.
The present invention compared with prior art has following effect: the present invention can effectively simulate interference and the gap that occurs between each parts in the assembling process by the method for KBE simulation, occurs the trouble that the gap is difficult for adjustment after avoiding assembling, and brings difficulty to assembling.Needing to obtain the cupping tool model of assembling by adjusting clearance between punch and die and the actions such as guiding, discharging and push piece, the assembly method of this model can be used for instructing the die assembly production line, shortens the die debugging cycle, improves mould production efficiency.
Description of drawings
Fig. 1 is automobile panel cupping tool assembly flow charts; Fig. 2 is the base installation diagram of drift and mould.
The specific embodiment
The specific embodiment one, describe with reference to Fig. 1 and 2, present embodiment is assembled into example with the base 2 of drift 1 and mould, makes a detailed description based on the concrete assembly method of KBE theory.
Step 1, analysis car panel die fittage determine that the required part of die assembly is comprised of drift 1 and base 2, and assembling process requires base 2 endoporus axle center and drift 1 axis coinciding, and the plane contact of the plane of drift 1 and base 2;
Step 2, according to the die assembly task analysis result of step 1, set up drift 1 and base 2 Parametric Model Libraries in the cupping tool of KBE, select in the part geometry model library and will assemble concrete part, and determine that according to major part processing and structural dependence the standard that assembles is base 2;
Step 3, obtain standard according to step 2, add respectively assembly features, restriction relation and the reference for assembling of base 2 and drift 1, wherein restriction relation is contiguity constraint and with one heart constraint, and reference for assembling is provided with consult straight line and reference point;
Step 4, two Assembly of the parts determining according to step 3 concern that take base 2 standards as benchmark, rule-based reasoning is assembled, and sets up drift 1 component assembling model;
Step 5, the component assembling model that obtains according to step 4, interfere detection, in order to analyze the collision between parts, contact and gap situation, if any interference, this model is designed and revises (drift 1 and its base 2 installation diagrams are interfered verification, and check results shows both no-floats, realizes the expection purpose);
Step 6, according to the assembling model that step 5 obtains, finish this component assembling model.
