【摘要】 本文主要进行了船体型材逆直线加工的计算系统和逆直线数控划线机的研究。 1.进行了船体型材逆直线加工的计算系统软件的开发。详细探讨了逆直线的原理及模型建立和求解过程。并在这个基础之上,进行了计算系统的软件开发。本系统以Windows为系统平台,VisualC++为软件平台进行开发。该系统可以根据船型信息和船体型值进行给定分段上的肋骨,横梁,纵骨等进行逆直线设计,在屏幕上给出逆直线图形,可以用打印机打印图形。系统可将计算所得的数据转换为实际加工所需要的数据格式。为系统添加了数据库读取和网络功能,使得现场计算机可以和设计部门实现资源共享。 2.进行了逆直线数控划线机的研究。本数控划线机主要为船舶建造及大型金属结构型材弯曲加工时划线及开孔而研制。本划线机全部采用箱式机构,尤其轨道采用箱式机构后刚性好,安装方便。纵横均配有无间隙传动装置,纵向(x轴)沿高精度轨道做直线运动,横向(y轴)和上下(z轴)双导杆运动。大小车驱动装有直流或交流伺服传动系统,并配有行星减速机构,z轴采用永磁直流电机和行星齿轮箱。划线装置主要有管道、氧气、乙炔、减压阀、电磁阀、回火器及划线枪组成,并装有自动点火装置,全部的操作都在数控工作台上自动完成。 在本课题的研究里,从逆直线的计算到逆直线的绘制,实现了无图纸的信息流动。而且计算逆直线的原始数据来源于设计图纸的肋骨型值,这样就可以将该逆直线的计算过程纳入到数学放样系统之中,从而使逆直线的数据能和其他加工数据一体化输出。 船体型材加工逆直线方法及划线机研究可以提高造船工业中的型材弯曲加工效率,缩短造船周期,减轻劳动强度。课题研制的划线机的目标是:不仅适应批量生产的需要,也能满足流水线的需要,为船体型材加工自动化和CIMS系统开发创造有力的条件。同时以可以服务于肋骨冷弯机,提高型材加工质量。

【Abstract】 This paper attempts to study two items: the software for ship frame anti-lines calculating, and the CNC machine for anti-lines drawing.1. Study for the software that is used to calculating and drawing the anti-lines. This paper studies the anti-lines theory and it’s mathematic model detailed. This software takes 586 computer as it’s hardware plate, Windows as system plate, and VC++ as software plate. This software can calculate anti-lines and draw the sketch map according to the data provided by the design section. And this software can get the data from the database in the computer of the design section by using the network.2. Study for the machine that is used to draw lines and pinch holes in ship building and large-sized metal structure bending. This machine takes the structure like box, and this structure makes machine have better rigidity and be fixed expediently. Transmission equipments without clearance are taken in landscape orientation and upright of machine. The equipments for drawing lines include: conduit, oxygen, acetylene, decompressed valve, and electromagnetism valve.In this study, from the anti-lines calculating to the anti-lines drawing, the information flows without blueprint. The data needed by the calculation system is provided by the design section.The study can improve the efficiency of frame bending for shipyards. The machine used to draw lines must adapt to a batch production, can be used in automatic produce line, and can serve for the machine for frame bending.
