Although the factory handicraft industry is relatively backward, it has trained and created many skilled workers. Although they are not experts in the manufacture of machines, they can manufacture a variety of hand tools, such as knives and saws. Needles, drills, cones, mills, shafts, sleeves, gears, bed frames, etc., in fact, the machine is assembled from these components.
2.1 The earliest trampoline designer, the Da Vinci trampoline, was called the “mother of machineryâ€. Speaking of trampoline, I have to talk about Da Vinci first. This legendary figure is probably the first designer of a trampoline for metalworking. The trampoline he designed is powered by hydraulic or pedals, the boring tool is rotated against the workpiece, and the workpiece is fixed on a mobile platform driven by a crane. In 1540, another painter drew a painting of "Fire Engineering" and also had the same trampoline chart. The trampoline was used to finish the hollow casting.
2.2 The first trampoline that was born for the processing of cannon barrels (Wilkinson, 1775). In the 17th century, due to military needs, the artillery manufacturing industry developed very rapidly. How to make the cannon's barrel became a popular one. A big problem to solve.
The world's first real trampoline was invented by Wilkinson in 1775. In fact, Wilkinson's trampoline is a drill that can precisely process cannons. It is a hollow cylindrical mast with both ends mounted on bearings.
In 1728, Wilkinson was born in the United States. When he was 20 years old, he moved to Staffordshire and built the first iron furnace in Bilston. Therefore, Wilkinson is known as the "master of blacksmiths in Staffordshire." In 1775, the 47-year-old Wilkinson worked hard in his father's factory to finally create a new machine that could drill cannon barrels with rare precision. Interestingly, after Wilkinson's death in 1808, he was buried in his own cast iron enamel.
