曲弯工艺 英语
1. What is the process of bending a metal sheet called?
The process of bending a metal sheet is called sheet metal bending.
曲弯金属板的过程被称为金属板弯曲。
2. What are the common methods of sheet metal bending?
The common methods of sheet metal bending are press brake bending, roll bending, and stretch bending.
金属板弯曲的常见方法有折弯机弯曲、卷曲和拉伸弯曲。
3. What is a press brake?
A press brake is a machine tool used to bend sheet and plate materials.
折弯机是一种用于弯曲金属板材的机床。
4. How does a press brake work?
A press brake works by clamping the sheet metal between a punch and a die. The punch is lowered, bending the sheet metal to the desired angle.
折弯机通过夹紧金属板材在冲压模和模具之间。冲头下降，将金属板弯曲到所需的角度。
5. What is the difference between air bending and bottom bending?
Air bending is a method of bending where the punch only touches the top of the sheet metal, leaving a gap between the punch and the die. Bottom bending is a method of bending where the punch touches the sheet metal and presses it into the die.
tablet press punch and die
空气弯曲是一种弯曲方法，冲头只接触金属板的顶部，留下冲头和模具之间的间隙。底部弯曲是一种弯曲方法，冲头接触金属板并将其压入模具中。
6. What is a hemming operation?
A hemming operation is a process of folding the edges of a sheet metal part over to create
a smooth and safe edge.
折边操作是将金属板零件的边缘折叠起来，以创建平滑和安全的边缘的过程。
7. What is a flanging operation?
A flanging operation is a process of forming a flange on a sheet metal part by bending the edge at a 90-degree angle.
翻边操作是通过将边缘弯曲成90度角，在金属板零件上形成一个法兰的过程。
8. What is a roll bending operation?
A roll bending operation is a process of bending a sheet metal part using a set of rolls to create a cylindrical shape.
卷曲操作是使用一组辊来弯曲金属板零件，以创建一个圆柱形状的过程。
9. What is a stretch bending operation?
A stretch bending operation is a process of bending a sheet metal part by stretching it over a die while holding it down at the ends.
拉伸弯曲操作是通过将金属板零件拉伸到模具上，同时在两端固定住它来弯曲的过程。
10. What are the advantages of sheet metal bending?
The advantages of sheet metal bending include the ability to create complex shapes, high accuracy and repeatability, and the ability to work with a variety of materials.
金属板弯曲的优点包括能够创建复杂的形状、高精度和可重复性，以及能够使用多种材料。
