Description
Technical field
The invention belongs to CAPP System technical fields, and in particular to a kind of intaglio press printing equipment
Assembly sequence-planning system and planing method.
Background technique
Assembly sequence-planning is on the basis of Product Assembly eigenmatrix, to the assemble sequences of components according to certain
It is sixty-four dollar question in complex product production assembly technology it is required that being planned and being selected.According to statistics, some industrialized
Country, the people that 30% is had more than in the manufacturing process of complex product are carrying out and are assembling relevant operation, the assembly man-hour of product
The half or so when manufacturing chief engineer is accounted for, assembly cost accounts for the 30%-50% of total manufacturing cost.Shared by the assembling process of complex product
The specific gravity of entire production cycle is larger, so carrying out Sequence Planning to its assembly informationmodel, can greatly reduce assembling process
The time of middle cost reduces production cost, reduces the design cycle of product.
During the assembly sequence-planning of complex product, comprehensively considers the geometric feasibility in assembling process, assembles
Operational stability, redirects the factors such as number and tool changing number at stability of strutting system.Establish the overall merit of assembly sequence
Index.Yin Ji manufacturing enterprise is limited in intaglio press Design and manufacturing process by operating experience, is designed, manufactures and is assembled
Etc. links cannot realize information interchange well, this has resulted in most of designer to the manufacturing process and dress of product
Lack with craftsmanship and deeply understands, and most of assembly crewman also lacks design process and explicitly recognizes, in assembling process
Highly dependent upon artificial subjective experience.
Intaglio press printing equipment is assembled as the key link in intaglio printing press manufacturing process, at present under realistic situation according to
So there is extensive artificial the phenomenon that solving assembly sequence, relies heavily on artificial subjective experience to determine to solve, do not have more
There is a unified evaluation index, therefore is extremely easy to produce carelessness and the phenomenon that mistake selects scheme, so that production efficiency reduces, it is raw

The assembly sequence-planning system of print machine printing equipment, including connect with database Assembling resource management module, assembly sequence rule
Module and Virtual assemble emulation module are drawn, using discrete particle cluster gravitation searching algorithm, calculates and chooses intaglio printing press printing
The program results of device components assembly sequence, the complexity of assembly sequence-planning are low.It is disadvantageous in that existing for the system
Algorithm used is not particularly suited for the assembling process of large-scale complex part.Jiangsu University of Science and Technology Zhou Honggen et al. establishes a kind of ship
Body block assembly Sequence Planning system carries out segmentation planning to the assembly of hull by integrating the Assembling resource information of hull, but
The shortcomings that being the system, is development cost height, and the investment of later period O&M is excessive.
Due to the characteristics such as production process complexity, the influence factor of intaglio press be numerous, lead to its key components and parts
Assembly process planning difficulty is larger, it is long to formulate the period, technique superior and inferior evaluating process is complicated；Currently, the print machine manufacture of most of China
The assembly technology of enterprise, which is formulated, mostly to carry out according to the experience of existing design manufacture, and micro-judgment lacks corresponding standard file and refers to
Lead, assembly technology formulation process slowly and its quality stability there is also larger hidden dangers；Existing print machine assembly technology knowledge
Lack and arrange and inherit, leads to technology establishment process repeatedly, substantially prolong the entire production cycle；Moreover, the assembler formulated
Skill lacks corresponding evaluation and verifying system, so that the superiority and inferiority of assembly technology is difficult to carry out the evaluation of indexing, this also gives reality
Production process bring problems.
