The Production Technology of Motorcycle Lower Link Plate

Abstract

The invention relates to a process for manufacturing a motorcycle lower yoke plate. The process includes the steps of conducting early-stage manufacturing of a die to make early-stage preparation for forging and stamping, conducting forging and stamping forming to forge and stamp the die into a lower yoke plate finished product, conducting heat treatment to improve hardness of the lower yoke plate, conducting shot blasting to remove oxide skins which are formed on the surface of the lower yoke plate due to forging, stamping and heating, conducting flaw detection to ensure that the surface of the product is free of cracks, and conducting rust preventive packaging to prevent rusting. According to the process, secondary quench hardening is conducted on the die, and therefore the hardness of the die is improved, the material walking effect in the forging and stamping process is improved, and a heat treatment method is suitable for dies which work at the temperature ranging from 400 DEG C to 450 DEG C.

Description

technical field [0001] The invention relates to a production process of a motorcycle lower connecting plate. Background technique [0002] As an essential part of motorcycles, the lower connecting plate has a complex shape, so its production process is also relatively complicated, especially in the forging forming stage, which is difficult, difficult to feed the blank, and has a high production scrap rate. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned disadvantages in the prior art, and provide a production process of the lower connecting plate of a motorcycle with a reasonable structural design, which can reduce the difficulty of feeding blanks and improve the qualified rate of products. [0004] The technical solution adopted by the present invention to solve the above problems is: the production process of the lower connecting plate of the motorcycle, which is characterized in that the production process compr...
