Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in the figure, the cylinder gasket for grooving between cylinders comprises a cylinder gasket body 11 and rivets 3, wherein the cylinder gasket body is formed by combining four layers of an upper plate 4, a middle plate 5, a lower plate 6 and a reinforcing plate 7, the upper plate 4, the middle plate 5, the lower plate 6 and the reinforcing plate 7 are connected through the rivets 3, the reinforcing plate 7 is located below the lower plate 6, a cylinder opening 1, bolt holes, cooling liquid holes and lubricating oil holes are formed in the cylinder gasket body 11 according to the specification of a gasoline engine, full-corrugated sealing ribs 12 are adopted at the cylinder openings 1 of the upper plate 4 and the lower plate 6, sealing rings 2 are arranged on the periphery of the cylinder opening 1, and the sealing rings 2 are located between the upper plate 4 and the middle plate 5. The sealing rib 12 widens from cylinder to cylinder. And balance ribs 8 are additionally arranged on the outer edges of the half ribs of the lower plate bolt hole, the cooling liquid hole and the lubricating oil hole. The upper plate 4, the lower plate 6 and the sealing ribs 12 are printed with a double-layer rubber coating 10.
The working principle is as follows: the cylinder gasket body 11 adopts a four-layer plate structure, bolt holes, cylinder opening holes 1, lubricating oil via holes, cooling liquid via holes and the like are punched on the upper plate 4 and the lower plate 6 by a stamping process, full-corrugated sealing ribs 12 are manufactured by the stamping process, and micro-sealing rubber wires are manufactured at the sealing ribs 12 by a screen printing process.
