Problems solved by technology
This cylinder head gasket is made of upper and lower two-layer metal plates. Sealing ribs are arranged independently on the cylinder holes of the metal plates. Since the sealing ribs are directly formed on the metal plate, the sealing ribs are easy to deform if used for a long time, and are made of Two layers of metal plates are superimposed, the production process is complicated and cumbersome, and the production cost is high

Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] Such as Figure 1 to Figure 4 Shown, the preparation method of the cylinder gasket of the present embodiment, the steps of this preparation method are:
[0023] 1. A single-layer stainless steel plate 1 with a thickness of 0.45-0.55mm is used as the body of the cylinder head gasket, and the cylinder mouth hole 11, water hole, oil hole, push rod hole and positioning hole 12 are stamped and formed on the stainless steel plate 1, and are placed on the cylinder pad. On the edge of the mouth hole 11, there is a downwardly protruding annular rib 13 formed by stamping;
[0024] 2. Perform surface treatment on the stamped stainless steel plate 1, glue and dry it;
[0025] 3. Use fluororubber as a raw material to make a vulcanized fluororubber formula. After mixing, refining, sheeting, cutting, weighing, and step 2, the treated stainless steel...

Abstract
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.
Description
technical field [0001] The invention relates to an engine component, in particular to a method for preparing a cylinder gasket of a diesel engine. Background technique [0002] Cylinder head gasket is one of the parts of piston compressor, which is located between the cylinder block and the cylinder head of the internal combustion engine. The sealing of the chamber prevents the leakage of the cylinder and the leakage of the water jacket. With the continuous strengthening of internal combustion engines, the thermal load and mechanical load are increasing, so the sealing effect of the cylinder head gasket is becoming more and more important. In the past, most of the cylinder gaskets used rubber sealing rings, which could not meet the requirements of users. At present, most of the cylinder gaskets use metal structures, such as the Chinese invention patent "Full Metal Cylinder Gasoline Engine Gasoline Engine Gasket Gasoline Engine Gasket" with the patent number CN200910108665.3...
