Method for preparing cylinder gasket

汽缸垫的制备方法

Abstract

一种汽缸垫的制备方法,其特征在于步骤为:以单层的不锈钢板作为汽缸垫本体,冲压成型有缸口孔、水孔、油孔、推杆孔和定位孔,在缸口孔的边缘上冲压成型有一向下凸的环形凸筋;将冲压后不锈钢板进行表面处理;以氟橡胶为原料配成硫化氟橡胶配方,经过混炼与不锈钢板进行加热注压硫化、再硫化,在水孔、油孔、推杆孔的位置包覆氟橡胶密封圈,在不锈钢板外边缘包覆氟橡胶包边;不锈钢基材冲压制作缸口孔护圈,将缸口孔护圈装配在缸口孔上,最后修边、整平后检验合格进行包装即可。本发明制备工艺先进、工序简单,制得的汽缸垫外观整洁、密封性能好、安装简单且成本较低,可与汽车、工程机械、船舶、发电等多个领域的柴油发动机配套适合。
A method for preparing a cylinder gasket is characterized by comprising the following steps: using a single-layer stainless steel plate as a cylinder gasket body, molding a cylinder opening hole, a water hole, an oil hole, a push rod hole and a positioning hole through stamping, and molding an annular rib protruding downwards in the edge of the cylinder opening hole through stamping; carrying out surface treatment on the stamped stainless steel plate; utilizing fluororubber as a raw material to prepare a sulfide fluorine rubber formula, carrying out heating, injection molding, vulcanization and second vulcanization on the stainless steel plate through mixing, coating fluororubber seal rings in the positions of the water hole, the oil hole and the push rod hole, and wrapping a fluororubber bordure on the outer edge of the stainless steel plate; stamping a stainless steel base plate to manufacture a guard ring for the cylinder opening hole, assembling the guard ring for the cylinder opening hole on the cylinder opening hole, finally trimming and leveling, and after detecting the cylinder gasket is qualified, packaging. The preparing technology is advanced, the procedures are simple, and the made cylinder gasket has tidy appearance and great seal performance, is simple to mount, is low in cost and can be matched with diesel engines in the multiple fields of automobiles, engineering machinery, ships, power generation and the like.
