mandrel弯曲工具

Mandrel Bender Tooling

的目的使用芯棒当弯管我s to prevent the tube from flattening and to prevent wrinkles and kinks. To achieve this, the mandrel is held in a fixed position, and the tube is pulled over it. The tube stretching process is localized on the outer radius of the bend, and the material is work-hardened to retain its shape and not flatten. The material stretching is done on the forward tip of the mandrel. This force, acting on the mandrel tip, supports the inner radius of the bend, holding it firmly into the bend die groove.

5Mandrel弯曲的必要组件

这mandrel，或mandrel组装，consists of a mandrel body, mandrel nose insert, a mandrel link or insert link, mandrel screw, and (if needed) a ball subassembly. The mandrel is the part of the rotary-draw tube-bending process to maintain the shape of the tube as it sets into the arc of the bend.

这mandrel is the tooling component that provides support to the inside of the tube. Its primary function is to prevent the tube from buckling and necking. Many different variations of mandrels exist. The required style and material depend on the outside diameter (OD) and wall thickness (WT) of the tube being bent. The simplest design style is the plug mandrel, and the most complex design style is the ball mandrel. The ball mandrel is designed to internally support the tube beyond tangent and depending on the number of ball segments, throughout the entire bend.

这bend die是形成管子以产生所需弯曲半径的主要工具。这是将管子夹紧的形式，然后在周围拉动以产生弯曲。弯曲模具的基本规格是外径和管子的弯曲半径弯曲。

这wiper diekeeps the tube from wrinkling during the bending process. A wiper die is required when the tube’s resistance to compression is high.

一种clamp die旋转以形成弯曲时，将管道材料夹在弯曲模具上。在夹具模具中有两个主要的规格；长度和空腔纹理，彼此相关。夹子越短，腔表面必须越粗糙，才能保持握力在管子上的力。锯齿，膝盖和碳化物浸渍使腔表面粗糙，这改善了夹具对管的握力。

一种压力死亡将管子固定在弯曲处的弯曲状态下，在切线处的恒定压力下，并沿弯道沿着管道。追随者的压力类型在弯曲过程中向前传播，几乎所有现代的旋转式弯曲机都配备了这种压力。

在大多数弯曲机上，两个设置控制压力模具的操作：直接压力和辅助压力。为了减少弯曲点上的阻力，必须将直接压力保持在所需的最低限度，以保持管子与弯曲模腔分离的情况。
