Problems solved by technology

The existing cylinder pads have the problems of low strength, poor sealing performance, poor high temperature resistance, poor guiding performance and poor stability
The currently used stamping dies for cylinder head gaskets have certain defects, such as incomplete removal of waste, low production capacity, small number of stampings per die, lack of fastening mechanisms, and poor knife edge toughness.
[0003] The start and development time of domestic automobiles is short, the production process of cylinder head gasket is immature, and the development speed is slow. In addition, the domestic process supervision and development of cylinder head gasket is relatively weak, and the development of cylinder head gasket process is relatively imperfect.

Embodiment example 1

[0030] The specific operation steps of the described cylinder head gasket processing technology are as follows:

[0031] Procurement of raw materials: Purchasing the required raw materials for cylinder head gasket production, iron-based powder 15%-30%, copper-based powder 10%-25%, engine oil 1%-4%, tackifier 0.6%-0.9%, Preservative 0.1%-0.4%, oxidant 0.3%-0.6%, graphite 20%-35%, resin 7%-10%, friction performance modifier 1%-2.5%.

[0032] Thermoforming stage: Pour the mixed and processed raw materials into the mold for raw material production, and use a double-piece thermoforming machine tool to obtain the blank raw material of the cylinder head gasket with the help of pressure. There are many processing methods for thermoforming, which are not limited to the two-piece thermoforming mentioned in the present invention, and also include mold forming and differential pressure. The hot pressing conditions are in a high-collar induction heating piezoelectric furnace with a temper...

Abstract

The invention discloses a cylinder head gasket processing method. The cylinder head gasket mold is composed of a lower mold and an upper mold, and the lower mold includes a lower mold guide plate and a guide column inside the connection part of the lower mold, a lower mold base and other parts of the lower mold; The upper mold includes an upper mold guide plate and a guide sleeve inside the upper mold connection part, an upper mold base and other parts of the upper mold; the lower mold base is surrounded by waste knives; the upper mold base is surrounded by trimming knives, The edge trimming knife is fixed on the base of the upper mold by bolts. There are various punching holes inside the edge trimming knife, and the punching holes are also installed on the base of the upper mold. The cylinder gasket processing process includes: raw material procurement, thermoforming stage, mold forming stage, hot pressing forming stage, heat treatment stage, surface treatment stage, grinding and polishing stage and parts testing, the present invention specifies and perfects the processing flow steps of the cylinder head gasket on the basis of improving the mold production efficiency, thereby further improving the cylinder head gasket. quality.

Description

technical field [0001] The invention relates to the field of cylinder gaskets, in particular to a cylinder gasket mold and a processing method thereof. Background technique [0002] Cylinder head gasket, also known as cylinder liner, is located between the cylinder head and the cylinder block. Its function is to fill the microscopic pores between the cylinder head of the cylinder block and ensure good sealing at the joint surface, thereby ensuring the sealing of the combustion chamber and preventing Cylinder leak and water jacket leak. According to different materials, cylinder gaskets can be divided into metal-asbestos gaskets, metal-composite gaskets and all-metal gaskets. The cylinder head gasket is the seal between the top surface of the body and the bottom surface of the cylinder head. Its function is to keep the cylinder seal from leaking air, and to keep the coolant and oil flowing from the body to the cylinder head from leaking. The cylinder head gasket is subject...
