**Main Features of Hand Feed Hairpin Bender or Semi-Automatic Hairpin Bender**
The semi-automatic hairpin bender is a compact and efficient machine designed for low-volume production of hairpin bends. It can produce hairpin benders ranging from 200mm to 3000mm in length, making it ideal for small-scale manufacturing.
The hand-fed (or semi-automatic) hairpin bender is capable of producing 2, 3, or 5 pieces per cycle, depending on the specific requirements and application. This flexibility makes it suitable for a wide range of industries that require precision and consistency in their bending processes.
**Structural Characteristics of the Semi-Automatic Hairpin Bender:**
1. **Compact Design:** The machine is built with a space-saving layout, making it easy to integrate into existing production lines.
2. **Servo Motor Driven:** Ensures precise and controlled movement during the bending process.
3. **Manual Feeding:** Operators manually feed the material, offering greater control over the process.
4. **Dual Operation Modes:** Can be operated in either manual or automatic mode, depending on the user's preference and task requirements.
**Automatic Operation Process:**
Material feeding (manual) → Mould tooling clamping → Oil spraying → Bending → Mandrel retraction → Clamp release → Unloading → Unloading to home position → Bending tooling returns to home.

The Song Dynasty, which lasted from 960 to 1279 AD, was a period of great cultural and technological advancements in China. During this time, the Song Dynasty produced some of the finest swords in Chinese history.
The Song Dynasty sword, also known as the "Jian," was a double-edged straight sword that was highly regarded for its craftsmanship and effectiveness in combat. It was primarily used by the military elite, including generals and officers.
The Song Dynasty sword had a distinctive design that set it apart from earlier swords. It featured a slender and straight blade, typically measuring around 70-90 centimeters in length. The blade was made from high-quality steel, which was renowned for its durability and sharpness.
One of the unique features of the Song Dynasty sword was its hilt, which was often adorned with intricate carvings and decorations. The hilt was usually made from materials such as jade, ivory, or precious metals, showcasing the wealth and status of the sword's owner.
The Song Dynasty sword was known for its versatility in combat. Its lightweight design allowed for quick and agile movements, making it suitable for both thrusting and slashing attacks. The sword's sharpness and durability made it highly effective in close-quarters combat, and it was often used in conjunction with other weapons, such as spears or bows.
