Production process for motorcycle wheel hub

Abstract

The invention discloses a motorcycle hub production process, including 1) smelting and component analysis; 2) casting; 3) cutting and drilling; 4) deburring; 5) heat treatment; 6) calibration; 7) shot blasting; 8) valve drilling Hole; 9) Hardness test 10) Processing 11) Spline pulling 12) Impact test; 13) Air tightness test; 14) Cleaning, spraying; 15) Finish paint; 16) Pressing; 17) Assembly; 18) Packaging ; This processing technology improves and adjusts the processing steps. Through process improvement, the appearance quality of the product can be improved to meet higher customer quality requirements. It can improve the product's anti-injury ability, protect the product from oxidation, and reduce molds and save mold costs. , shorten production and processing time, and improve processing efficiency.

Description

technical field [0001] The invention relates to a production process of a motorcycle hub. Background technique [0002] The original motorcycle wheel hub is processed by drilling the valve hole --- deburring --- heat treatment --- shot blasting. The position of the valve hole of the product is dull, dull, and the surface quality is poor, which cannot meet the high requirements of customers. [0003] Secondly, when the traditional motorcycle wheel products need to be sprayed and the car is bright, there will be more or less aluminum chips flying out during processing, resulting in poor appearance of the product, often causing the product to be repaired due to the damage, thereby slowing down the work efficiency and product turnover. The traditional way is to protect by replacing the anti-scratch paint or increasing the baking temperature. Although this has a certain effect, it cannot fully meet the customer's needs for the specified color products. At the same time, the baki...

Problems solved by technology

[0002] In the processing technology of the original motorcycle wheel hub, the product is drilled valve hole --- deburring --- heat treatment --- shot blasting, the valve hole position of the product is dim, dull, and the surface quality is poor, which cannot meet the high requirements of customers

[0003] Secondly, when the traditional motorcycle wheel products need to be sprayed and the car is bright, there will be more or less aluminum chips flying out during processing, resulting in poor appearance of the product, often causing the product to be repaired due to the damage, thereby slowing down the work efficiency and product turnover

The traditional way is to protect by replacing the anti-scratch paint or increasing the baking temperature. Although this has a certain effect, it cannot fully meet the customer's needs for the specified color products. At the same time, the baking temperature is too high, and it is easy to cause discoloration, blistering, etc. defect

[0004] Thirdly, in traditional motorcycle wheel production, a single front wheel or rear wheel product requires a single mold, which directly leads to an increase in the investment in molds in product development. Since it needs to be produced on a separate machine, this method has greatly reduced production efficiency And the probability of problems with the mold itself

When customers provide cross-brand products of different models and products of the same brand series, the development cycle, sample and production cycle often increase
