【摘要】：可发性聚苯乙烯泡沫塑料(EPS),俗称苯板、泡沫板,被广泛地应用于建筑装修装潢、道路施工、电影道具布景、包装箱体等很多的领域,有着广阔的市场需要和使用价值。目前针对EPS板材主要有三种不同的加工方式:第一种是手工切割,即采取绝缘措施后由工人手持电热切割丝切割板材,切割的形状和位置完全由人工决定,缺点是加工精度无法保证,加工效率极低且存在一定的安全隐患;第二种是机器简单切割,目前市场上也存在着一些EPS板材的造型设备,主要有片块样式切割设备、装饰用线条类切割设备、仿照形状类数控切割设备等,缺点是这些设备都只能对EPS板材进行简单的造型切割,无法实现成批量、流水线、智能化切割;使用效果更好的承插式EPS板材的生产主要采用的是注塑的方式,由于需要制作专门的模具,因此成本很高,生产效率不高,无法实现大范围的推广和使用。通过智能EPS板材切割调控系统和机械平台的配合,(1)实现对于EPS板材的6面造型的切割;(2)接受PC机发出的指令,完成切割时电热切割丝切割速度(位置)的数值控制,提高切割加工时切口表面的质量和精度,完成燕尾类槽、锯形类槽、梯形类槽等各种不同形状和尺寸的槽的切割;实现欧式建筑檐线、脚线、罗马柱体等异形体的切割;并把常用形体的切割数据固定化,便于成批量反复切割生产;(3)实现电热切割丝的温度(电流)、张紧度和电热切割丝的切割速度的合理匹配,完成温度(电流)及速度的调节,实现高精度、高效率、高质量,低能耗、低成本、低废品率的目标,最终达到承插式EPS板材流水线切割的要求。因此,针对EPS板材,进而延伸到消失模的切割,研究出一套合理的智能切割调控系统对于促进EPS板材切割技术的发展和相关行业的推广应用都有着十分重要的现实意义。本文通过研究适用于电热切割丝切割的智能切割调控系统,并制造出相应的机械应用平台,论证系统的可行性与实用性,同时通过设计相关因素的实验,寻找影响切割效果的几个因素之间的关系,为EPS板材的合理切割提供合适的实验数据和结论支撑。
[Abstract]:EPS, commonly known as benzene board, foam board, is widely used in many fields, such as decoration, road construction, film props setting, packaging box and so on. At present there are three different processing methods for EPS sheet: the first is manual cutting, that is, after taking insulation measures, the workers hold the electric heat cutting wire to cut the plate. The shape and position of the cutting are completely determined by manual, the shortcomings are that the machining precision can not be guaranteed, the machining efficiency is extremely low and there are certain safety risks. The second one is simple machine cutting. At present, there are some modeling equipment of EPS sheet in the market, mainly cutting equipment in block style, line cutting equipment for decoration, NC cutting equipment for copying shape class, and so on. The drawback is that these equipments can only cut EPS sheet simply, can not realize into batch, pipeline, intelligent cutting; The production of EPS plate with better effect is mainly by injection molding, because of the need to make special mold, so the cost is very high, the production efficiency is not high. It can not be popularized and used in a wide range. Through the intelligent EPS board cutting control system and the coordination of the mechanical platform, we can realize the EPS sheet 6-sided shape cutting; 2) accept the instruction of PC, complete the numerical control of cutting speed (position) of electrothermal cutting wire, improve the quality and precision of cutting surface, finish the groove of swallowtail and sawing. Trapezoidal grooves and other different shapes and sizes of slot cutting; To achieve the European building eaves, foot lines, Roman columns and other shaped body cutting; The cutting data of common objects are immobilized to facilitate the repeated cutting production in batches. The temperature (current, tension) and cutting speed of electrothermal cutting wire can be reasonably matched, and the adjustment of temperature (current) and speed can be completed, so as to achieve high precision, high efficiency and high quality. The goal of low energy consumption, low cost and low scrap rate is to meet the requirements of EPS board pipeline cutting. Therefore, for EPS plate, and then extend to EPC cutting. It is very important to study a reasonable intelligent cutting control system for promoting the development of EPS sheet cutting technology and the popularization and application of related industries. This paper is suitable for electrothermal cutting wire cutting. Intelligent cutting control system for cutting. And the corresponding mechanical application platform is made to demonstrate the feasibility and practicability of the system. At the same time, through the design of the experiment of related factors, the relationship between several factors that affect the cutting effect is found. Provide suitable experimental data and conclusion support for reasonable cutting of EPS sheet.
