Energy-saving production technique for lower yoke plate of motorcycle

Abstract

The invention relates to an energy-saving production technique for a lower yoke plate of a motorcycle. According to the energy-saving production technique for the lower yoke plate of the motorcycle, the manufactured lower yoke plate is small in hardness scattering difference and high in hardness uniformity; and compared with a production technique for a lower yoke plate of a motorcycle in the prior art, the one-piece energy consumption is reduced by about 55%, and the one-piece cost is reduced by about 56%. Compared with the prior art, the energy-saving production technique for the lower yokeplate of the motorcycle has the beneficial effects that a heat-treatment line including line-frequency induction through-heating, oil bath quenching and mesh-belt furnace tempering is used for replacing a traditional quenching furnace heat-treatment line, therefore, the heating stability and uniformity of a mould and the cooling uniformity of the mould in the cooling process can be improved greatly, it is guaranteed that all parts can be cooled with the extremely-high relative synchronization degree, the hardness scattering difference of the mould is reduced greatly, and the hardness uniformity is improved; and compared with a traditional heat-treatment method, the energy consumption can be reduced greatly.

Description

technical field [0001] The invention relates to an energy-saving production process of a mould, in particular to a prepared lower connecting plate with small hardness dispersion and high uniformity, and the energy consumption per piece is reduced by about 55% compared with the production process of the motorcycle lower connecting plate in the prior art. The energy-saving production process of the lower link plate of the motorcycle with a unit cost reduction of about 56%. Background technique [0002] A motorcycle is a two-wheeled or tricycle driven by a gasoline engine and steered by a handlebar. It is light, flexible, and fast-moving. It is widely used for patrolling, passenger and cargo transportation, etc., and is also used as sports equipment. From the general direction, motorcycles are divided into street cars, road racing motorcycles, off-road motorcycles, cruisers, station wagons and so on. [0003] As an essential part of current motorcycles, the lower connecting pl...
