Description

一种板式平焊法兰
技术领域
本发明涉及法兰技术领域,尤其涉及一种板式平焊法兰。
背景技术
法兰是一种连接工具,法兰连接是指由法兰、垫片及螺栓三者相互连接作为一组组合密封结构的可拆连接。法兰分螺纹连接(丝扣连接)法兰、焊接法兰和卡夹法兰。法兰连接因其连接密封性好、结构稳固、强度高、使用方便、成本低等优点,被广泛应用于建筑行业、城市供水、锅炉压力容器、石油行业、供气、化工行业、食品业、消防、制药行业、电站、水利、暖通等行业。
平焊法兰是法兰中的一种;由于它是近几年的产生的新工艺,仍然存在着不足:a、由于在卷曲过程外圆受拉伸,内圆受积压,致使卷制出来法兰毛坯总是内圆厚、外圆薄,如公开号为CN 1817556A的中国发明专利“一种法兰的制作方法”其热卷的条状扁钢的横截面为矩形,在卷曲时出现内外径厚度不等现象,下道工序乃至以后的精加工都带来麻烦,从而进一步浪费燃料资源和加大操作工序。因此为了保证外圆的加工量,必须加大毛坯整体的加工量,这就造成了加工量不能减少到最小,废料多。
发明内容
针对现有技术中的上述不足,本发明提供了一种板式平焊法兰,其制备简单,节约原材料,而且平整度好,使用方便,密封性好,成材率高,降低了加工成本,适合推广实施,具有较好的社会和经济效益。
为了达到上述发明目的,本发明采用的具体方案为:
一种板式平焊法兰,包括钢坯及密封垫,所述密封垫包括下列重量份的组份:丙烯酸酯橡胶70-75份、氯丁橡胶20-25份、炭黑24-28份、纳米云母12-18份、苯并三氮唑2-3份、聚乙二醇2-3份、环烷酸钴1-2份、硬脂酸钙1-2份、纳米陶土20-25份、偶联剂1-2份、促进剂1-2份、硫磺1-2份、氧化锌2-3份、改性凹凸棒土10-12份。
进一步,所述板式平焊法兰的制备方法包括以下几个步骤:
(1)按照需要制作的法兰成品内径制作圆柱形模具备用,或者在可调整的圆柱形模具上调出所需法兰成品内径尺寸备用;
(2)将钢坯入炉加热至1100-1200℃;
(3)将钢坯出炉,在轧机上逐次轧压出扁条状的初轧钢坯,再在轧机上安装与所需要制作法兰成品的厚度、宽度,以及法兰成品端面上的凸面台阶或沟槽的宽度和高度相应的轧辊,在轧机上轧制出带有加工余量的凸面台阶或沟槽的热轧扁钢;
(4)将轧制后的带有凸面台阶或沟槽的热轧扁钢及时送入法兰热卷机内,启动热卷机使热轧扁钢围绕圆柱形法兰模具卷制出多圈螺旋圆环钢圈;
(5)沿多圈螺旋圆环柱体纵向切割使其被分割为单个带错口的圆环钢圈;
(6)将(5)中单个独立的圆环钢圈在700℃以上放入压力机上压平后再进行冷却;
(7)对冷却后的法兰毛坯进行校圆、割口焊接及焊后校平;
(8)对焊接后法兰毛坯以及毛坯上的凸面台阶或沟槽进行精加工制成法兰成品,套设适配法兰成品的密封垫。
本发明的有益效果为:
其制备简单,节约原材料,而且平整度好,使用方便,密封性好,成材率高,降低了加工成本,适合推广实施,具有较好的社会和经济效益。
