Production method of wear-resistant HT300 automobile clutch pressure plate

Abstract

The invention discloses a production method of a wear-resistant HT300 automobile clutch pressure plate, and relates to the technical field of automobile clutch pressure plates. The production method of the wear-resistant HT300 automobile clutch pressure plate comprises the steps of sand mixing, modeling, furnace charge smelting, tapping inoculation treatment, pouring, cooling, box opening and casting cleaning; and molten iron used for pouring comprises the following chemical components in percentage by mass: 2.9-3.4% of C, 1.5-2.6% of Si, 0.6-1.1% of Mn, 0.06-0.12% of S, less than or equal to 0.15% of P, less than or equal to 0.25% of Cr, less than or equal to 0.25% of Mo, less than or equal to 0.6% of Cu, less than or equal to 0.15% of Sn and the balance Fe and inevitable impurities. According to the production method of the wear-resistant HT300 automobile clutch pressure plate, a casting method and a casting device are adopted for producing the clutch pressure plate, the utilization rate of metal is increased by more than 40%, the working efficiency is improved by about 60%, the carbon content is high, the mechanical strength of castings of the obtained clutch pressure plate can meet the requirements, then the wear resistance of the pressure plate is improved, the elongation of the pressure plate is obviously increased, the manufacturing cost is reduced, and the practicability is higher.

Description

technical field [0001] The invention belongs to the technical field of automobile clutch pressure plates, in particular to a preparation method of wear-resistant HT300 automobile clutch pressure plates. Background technique [0002] The clutch is an important part of the vehicle power system, and it is responsible for disconnecting and connecting the power and the engine. When driving on urban roads or complex road sections, the clutch is one of the most frequently used parts. And the clutch pressure plate is an important structure on the clutch, and its function is very important to the driving safety of the car. There are friction plates on the clutch pressure plate, just like the brake plates on the wheels, which are very wear-resistant asbestos and copper wire. made. [0003] The pressure plate is a metal disc, which is a part of the automobile clutch. In the normal state, it is closely combined with the clutch plate to form a whole, rotates with the engine, and transm...
