Spin Forging Process.
Spin forging, also known as flow forming, is a metalworking process in which a rotating mandrel is pressed against a workpiece, causing it to deform and assume the shape of the mandrel. The process is typically used to produce hollow, cylindrical parts with complex geometries.
Process flow.
The spin forging process typically involves the following steps:
1. Preparation of the workpiece: The workpiece is typically a cylindrical blank made of a ductile metal, such as aluminum, steel, or titanium. The blank is mounted on a chuck and secured in place.
2. Mandrel selection: The mandrel is a cylindrical tool with the desired shape of the finished part. The mandrel is typically made of a hard material, such as tool steel or carbide.
3. Lubrication: A lubricant is applied to the workpiece and mandrel to reduce friction and prevent galling.
4. Spinning: The workpiece is rotated at a high speed while the mandrel is pressed against it. The force of the press causes the workpiece to deform and flow around the mandrel.
5. Forming: The workpiece is gradually formed into the desired shape as the mandrel is moved along its length.
6. Cooling: After the workpiece is formed, it is cooled to room temperature.
7. Trimming: Any excess material is trimmed from the workpiece.
Advantages of spin forging.
Spin forging offers several advantages over other metalworking processes, including:
High precision: Spin forging can produce parts with very precise dimensions and tolerances.
Complex geometries: Spin forging can be used to produce parts with complex geometries that would be difficult or impossible to produce using other methods.
High strength: Spin forging can produce parts with high strength and durability.
Low cost: Spin forging is a relatively low-cost process, especially for high-volume production.
Applications of spin forging.
Spin forging is used in a variety of industries,
including:
Automotive: Spin forging is used to produce a variety
of automotive components, such as wheels, gears, and shafts.
Aerospace: Spin forging is used to produce aerospace components, such as engine casings and fuel tanks.
Medical: Spin forging is used to produce medical implants, such as bone screws and artificial joints.
Electronics: Spin forging is used to produce
electronic components, such as heat sinks and connectors.

旋压成型工艺流程。

旋压成型，也称为径向锻造，是一种金属加工工艺，其中将旋
转芯轴压在工件上，使其变形并获得芯轴的形状。

该工艺通常用于
生产具有复杂几何形状的空心圆柱形零件。

工艺流程。

旋压成型工艺通常包含以下步骤：
1. 工件准备，工件通常是一个圆柱形毛坯，由铝、钢或钛等延性金属制成。

毛坯安装在卡盘上并固定到位。

2. 芯轴选择，芯轴是一个圆柱形工具，具有成品的预期形状。

芯轴通常由工具钢或硬质合金等硬质材料制成。

3. 润滑，在工件和芯轴上涂抹润滑剂以减少摩擦并防止擦伤。

4. 旋转，工件高速旋转，同时芯轴压在其上。

压力的作用使工件变形并围绕芯轴流动。

5. 成形，随着芯轴沿其长度移动，工件逐渐成形为所需形状。

6. 冷却，工件成形后，冷却至室温。

7. 修整，从工件上修剪掉任何多余材料。
