How did the machinery for making pins evolve over time?

Early simple tools stage
Hand forging period: In the early days of pin making, there was no special making machine, mainly relying on simple hand tools. Artisans use tools such as hammers and pliers to hammer, bend and shape the metal strip, forming the metal material into a rough pin shape. This method is inefficient, and the shape and size of the pins produced are not standardized.
Industrial revolution push stage
Introduction of mechanical power: During the Industrial Revolution, simple steam-powered pressing and bending machines appeared and began to be used for pin making. These machines use steam power to drive stamping dies and bending devices, stamping metal sheets or wire into the basic shape of the pin, compared to manual production, production efficiency has been greatly improved, and the shape and size of the pin is more uniform.

Special machines appeared: After the mid-19th century, with the further development of mechanical manufacturing technology, there were machines specifically used to make pins. For example, the emergence of integrated pin manufacturing machines that can automatically feed, press, bend and cut wire, these machines use gears, chains and other transmission devices to achieve partial automation of pin production, production efficiency and product quality have been significantly improved.
Stage of modernization since the 20th century
Automated production line: At the beginning of the 20th century, motor drive technology was widely used, and pin making machines achieved a higher degree of automation. The automated production line integrates the feeding, forming, assembly, surface treatment and other processes together, and can continuously and efficiently produce pins through the collaborative work of the motor, controller and mechanical transmission. For example, automatic pin assembly machines are available that automatically assemble the pin stem and base together.
Application of numerical control technology: in the late 20th century, numerical control technology was applied to pin making machines, which greatly improved the accuracy and flexibility of the machines. CNC bending machine, CNC punching machine and other equipment can accurately process metal materials according to the preset program, and can quickly adjust the processing parameters to produce pins of various shapes, sizes and specifications to meet the needs of different customers.
Intelligent and multi-functional: Into the 21st century, the pin making machine to intelligent and multi-functional direction. Some machines are equipped with sensors and visual inspection systems that can automatically detect the quality and size of pins and automatically eliminate unqualified products. At the same time, there are also a variety of functions in one of the pin making machine, such as can be completed in a machine steel wire straightening, punching, bending, riveting and other processes, like the pin rotary ring machine, can be automated assembly of the pin and rotary ring.
