As improvement, the inner peripheral surface of described opening is equipped with the metal collar of friction resistant.
Improving further, the upper and lower surface on the neighboring, local of described metal collar is respectively equipped with the reinforcement annular bar of end face and metal collar top flush, the width of described reinforcement annular bar is 2～4mm.
As improvement, the opening of described sealing gasket is four, and the quantity of described metal collar is corresponding with opening, and the overall collar that described metal collar is time processing is coated on the periphery of opening, and the degree of depth that described metal collar wraps into is 2～6mm.
As improvement, described overall structure being provided with fixed via, be equipped with the sheet metal that can be convenient for changing in described fixed via, described sheet metal is provided with fixing hole, the thickness of described sheet metal is 0.08～0.3mm.
The manufacture method of described cylinder seal pad, by following steps:
One, first the graphite linings of the specific thickness on upper strata is adhered on the surface in middle level by glue, lower floor is coated with and is placed on the bottom surface in middle level, and control the thickness of lower floor well；
Two, again by upper strata, middle level, under be placed in extrusion die carry out extruded；
Three, extruded sealing gasket is carried out deburring, be sealing member products formed；
Four, metal collar bound edge is carried out again；
Five, on sealing member products formed, it is brushed on paint, after airing, is finished product.
Compared with prior art, the utility model has the advantage of: be provided with, on the end face of sealing gasket and bottom surface, the convex tendon being disposably extruded from, sealing property can not only be improved and improve bend resistance intensity, and significantly have submitted production efficiency, production efficiency is made to improve more than at least three times than original production efficiency, thus it is greatly reduced labor intensity, it is effectively saved producing cost, and it is more accurate to have sealing station by the convex tendon being once extruded from, set because having at extrusion die, so it is more preferable to produce sealing gasket leakage efficiency, so that the service life of sealing gasket is longer；Further, cylinder seal is lined with three layers, and the upper and lower are respectively equipped with the reinforcement annular bar of end face and metal collar top flush, improves cylinder seal pad bend resistance ability；Being equipped with the metal collar of friction resistant on the inner peripheral surface of opening, extend the service life of cylinder seal pad, sealing effectiveness improves further, and the degree of depth that metal collar wraps into is 2～6mm, makes metal collar be difficult to get loose, improves sealing property further；Being provided with sheet metal on fixed via, it is convenient to change.And manufacture method in this utility model is very convenient, fabricating quality the most easily operates.
