Abstract

The invention provides a limiting method for a cylinder opening part of a cylinder gasket. The limiting method for the cylinder opening part of the cylinder gasket comprises the following steps: a) arranging an adjusting plate between two sealing function layers, and thinning and stretching the adjusting plate at the cylinder opening part; and hemming the stretched material, filling the hemmed material into the cylinder opening part, and flattening to form a limiting layer, so as to realize that the self material taking of the adjusting plate forms a limiting height difference at the cylinderopening part; wherein the adjusting plate is a soft cold-rolled plate. Compared with the prior art, the limiting method is based on the middle adjusting plate made of the specific material, the thinning and stretching technology is adopted, and a laser welding machine and extra welding materials do not need to be added, so that the cost is remarkably reduced; and moreover, the limiting method is high in efficiency and strength, the limiting layer and a body are integrated, no gap exists between the limiting layer and the body, and an impact of high-pressure fuel gas can be blocked, so that thelimiting function is guaranteed, and finally sealing with excellent stability is achieved.

Description

technical field

[0001] The invention relates to the technical field of cylinder gaskets, and more specifically, relates to a method for limiting the position of the cylinder port of the cylinder gasket. Background technique

[0002] The cylinder gasket is located between the cylinder head and the cylinder block, also known as the cylinder bed; its function is to fill the microscopic pores between the cylinder block and the cylinder head to ensure good sealing at the joint surface, thereby ensuring the sealing of the combustion chamber and preventing the cylinder Air leaks and water jacket leaks.

[0003] At present, the limit height difference of the cylinder head of the cylinder gasket (such as the metal cylinder gasket of a diesel engine) is formed by laser welding another material (SUS304), and then punched, see figure 1 shown. However, on the one hand, it is necessary to increase the laser welding machine and welding limit materials, and the cost of equipment and mater...
