摘 要

金属缠绕式垫片(简称缠绕式垫片)是应用最广泛的静密封垫片之一,典型的缠绕式垫片基本上是由具有“V”型截面的金属缠绕带和非金属填料带在同一芯轴上交替缠绕而成的。由于它具有多道密封的作用,且具有回弹性和密封性能好、对介质和温度的适应性强、耐压范围广、安装预紧力小、能吸收振动和冲击等优良特性,因此在炼油、化工、火电、核电等诸多工业部门中广泛地用作容器、设备和管道的静密封元件。

本文针对国内从事缠绕式垫片生产的厂家为数众多,其中大部分是地方性的小型企业,大多处于“生产无标准、工艺无规程、成品无检验、设备无控制”的落后状态,以至使国内缠绕式垫片的性能差异很大,其使用效果也达不到国外同类产品的水平的问题,设计了新型的缠绕垫片金属带成型机。本机器用于缠绕垫片生产过程中的金属带成型过程,平钢带经由导向轮进入一对成型轮,成型轮的结构按钢带最佳结构参数进行设计,将平钢带滚压成型为“V”型,保证成型后的钢带光滑、对称、不扭曲并符合规定的宽度。通过调节专用直流稳压器提供给轴端电磁离合器的激磁电压,实现成型后的钢带在卷带芯片上自动收卷。解决了传统生产设备劳动密集程度较大,生产效率难以提高,产品成本也难以降低以及废品率高的问题。

关键词:缠绕式垫片 金属带 成型 滚压 成型机

ABSTRACT

Metal spiral wound gasket (hereinafter referred to as spiral wound gasket) is one of the most widely used static sealing gasket, typical spiral wound gasket is basically have a "V" shaped cross section of non-metallic filler metal winding belt and belt on the same core shaft winding alternately. Because it has a multichannel sealing effect, and has a resilience and good seal performance, strong adaptability to medium and temperature, pressure range, installation pre-tightening force is small, can absorb the good qualities, such as vibration and shock in oil refining, chemical, thermal power, nuclear power, and many other industrial sectors in the widely used for containers, equipment and piping of the static sealing element.

Domestic, the author of this paper is engaged in production of spiral wound gasket manufacturer is numerous, most of them are local small businesses, mostly in the "top production, process procedures, finished product inspection, equipment without control" backwardness, to domestic spiral wound gasket performance difference is very big, its use effect also can not reach the level of similar foreign products, designed a new type of metal belt winding gasket machine. This machine used in the production of wound gaskets process of metal forming process, through the guide wheel into a pair of flat steel forming wheel, the structure of the forming wheel according to the steel with the optimum parameters of the structure design, the flat steel strip rolling forming for the "V" type, assure the smooth steel belt, symmetry, after forming not distort and the width of the provisions. By adjusting the special dc voltage stabilizer for shaft end electromagnetic clutch driving voltage, after forming of steel strip in the take-up of chip automatic winding. Solve the traditional labor intensive production equipment is bigger, difficult to improve production efficiency, product cost is difficult to reduce, and the problem of high rejection rate.

Keywords: Spiral wound gasket Metal belt molding rolling Molding machine
