I want to make a small clockwork generator, what do I need to prepare?

Oh! Your idea is a bit outdated. When primary battery technology was not yet available, a large number of toys, clocks, etc. were powered by mechanical springs. But now, there are all kinds of batteries in front of us, and their volume ratio, weight ratio, capacity ratio, price ratio, etc. All aspects of performance are far superior to clockwork power. Therefore, except if you want to experiment or experience the following clockwork, in terms of real practicality, it is better to use batteries.

The direction of the casting mold

The blade diameter is not professional, it should be the sweep diameter. The mainstream blade shapes are 126/110/114, etc., and the corresponding blade sizes are 68m, 54m, and 56m; now the diameter of the largest wind turbine blade has exceeded 70 meters, which is equivalent to the wingspan of a Boeing aircraft.

When it comes to materials, it’s more complicated. Different parts of the blade have different materials. Generally speaking, three categories are used, carbon fiber and fiberglass as the outer surface, and balsa wood and foam as the core. material.

The other thing is the binder. Carbon fiber is ideal because it has better strength and is lighter, but it is also a problem because it is too expensive. Balsa wood is balsa wood. As for foam, there are relatively many types, but they are generally hard foam. 3A products account for 90% of the share in this area.

The main materials of wind turbine blades are fiberglass fabrics and reinforced resins.

Large-megawatt blade spar caps may use a carbon-glass hybrid design, and the shell webs generally use glass. Fiber fabric

In addition to LM, mainstream domestic and foreign wind turbine blade manufacturers such as VESTAS, SIEMENS, GAMESA, etc. all use epoxy resin systems; LM relies on its own understanding of the interface ability between resin and fiberglass fabric, Using polyester resin, the bonding speed is fast, the post-curing process does not require heating, and the mold turnover efficiency is high;

The goal of casting molds is to sell them to users for service. When it flows into the hands of downstream users, it must be marketable. With the advancement of industrialization, judging from the development of the industry, in the future, the following six aspects will be the development direction of the casting mold industry.

The first one is intelligent casting molds that serve emerging strategic industries, and energy-saving and environmentally friendly casting molds that serve energy-saving and environmentally friendly industries;

The second one is the new generation of information technology industry Serving precision and ultra-precision casting molds with sensing and other functions;

The third is precision and ultra-precision casting molds for medical devices serving the biological industry;

The fourth is "high-end equipment Intelligent casting molds serving the "manufacturing industry";

The fifth is casting molds serving the new energy industry. These molds mainly include new blade molds for megawatt wind turbines, spindle molds and motor molds, etc. ;

The sixth is a casting mold serving the new energy automobile industry.

With the development of industries related to the casting mold industry, the casting mold industry must timely adjust its production scale and product structure, keep pace with the times, and betterGrasp future development trends to adapt to market needs in the new era.
