Problems solved by technology

[0002] The windshield is an important accessory on a motorcycle. It is traditionally made of tempered glass or plexiglass. When tempered glass is used, the windshield is heavy and has high requirements for installation and fixing, and it is easy to be damaged due to impact. The overall fragmentation, when using plexiglass processing, the plexiglass sheet is generally thermoformed first, and then the sheet is cut according to the needs. On the one hand, it is easy to cause scratches on the surface of the sheet during cutting, and on the other hand, it is easy to cut. A large amount of waste is produced during the cutting process, resulting in waste of raw materials, and the surface of the plexiglass is poor in friction and scratch resistance. During long-term use, it is easy to be scratched by dust and leaves carried by the wind, resulting in scratches and affecting sight.

Abstract

The invention discloses a motorcycle wind shield production process. The motorcycle wind shield production process comprises the following steps: firstly, selecting transparent polycarbonate particles in the corresponding specification according to product requirements to be dried; secondly, feeding the treated polycarbonate particles into an injection molding machine, and directly forming a base plate of a motorcycle wind shield through injection molding by the injection molding machine; thirdly, cooling and shaping the base plate of the motorcycle wind shield at the normal temperature, then removing grease and dust on the base plate of the motorcycle wind shield, and finally blowing the surface of the base plate of the motorcycle wind shield to be dry through a hot air blower; and fourthly, spraying a transparent epoxy protection layer to the face, facing the wind blowing direction, of the base plate of the motorcycle wind shield through spraying equipment, and trimming the edge of the base plate of the motorcycle wind shield after the epoxy protection layer is hardened to obtain a finished product of the motorcycle wind shield. By means of the above manner, the production efficiency of the wind shield can be improved, the production cost is reduced, the surface hardness is high, and scratching is not likely to happen.

Description

technical field [0001] The invention relates to the field of motorcycle accessories, in particular to a production process of a motorcycle windshield. Background technique [0002] The windshield is an important accessory on motorcycles. It is traditionally made of tempered glass or plexiglass. When tempered glass is used, the windshield has a heavy weight, requires high installation and fixation, and is prone to collisions. The whole is broken. When using plexiglass, the plexiglass sheet is generally thermoformed first, and then the sheet is cut as needed. On the one hand, it is easy to cause scratches on the surface of the sheet during cutting, and on the other hand, it is easy to cut. A large amount of waste is generated during the cutting process, resulting in waste of raw materials, and the surface of the plexiglass has poor resistance to friction and scratches. During long-term use, it is easy to be scratched by dust and leaves carried by the wind, resulting in scratch...
