大模型看图识别薄壁成型工艺

寂静回声

人从此图中能看到10'代表要成型的薄壁筒零件，101代表凸成形滚轮和芯棒及一侧端面，102代表凹成形滚轮。因为此薄壁圆筒没有两端端面，所以从图中还可以看到两端端面支撑工装。薄壁筒零件的旋转中心与芯棒旋转中心是不一致的，是偏的。而弯曲箭头的旋转中心明显与芯棒的轴线是一致的。
豆包大模型的识别

似乎豆包大模型看懂了图，但却把零件与零件号搞错了，把要成型的零件编号写成了101，而凹模具给识别成了径向力，那明明是个模具啊。

GPT-5的识别

Gpt-5的识别能力就是强，工件，模具和零件号都答对了，甚至看到了粗的黑色箭头。
但是GPT-5把描绘旋转的箭头理解成了流体运动方向，结果判断出现严重失误，说是什么液体胀形，离谱好吧。

这幅图展示的是一种薄壁圆柱件的成型工艺，从结构和工艺特征来看，属于典型的内高压成形（Hydroforming） 或 管材液压成形（Tube Hydroforming） 工艺。
分析如下：
关键部件识别：
101：表示被加工的管状毛坯（通常为金属管材），在图中呈弯曲状。
102：是模具或型腔的一部分，用于限制管材变形并赋予其最终形状。
10'：可能是密封装置或端部封头，用于封闭管材两端以便内部加压。
工艺过程：
管材被放置在模具（102）中，两端被夹紧或密封（由10'表示）。
通过向管材内部注入高压液体（如水或油），使管材内壁受压膨胀。
在内部压力作用下，管材贴合模具型腔，形成所需的复杂形状（如图中的U形或T形结构）。
外部模具提供支撑和约束，确保成形精度和防止过度变形。

102算是看对了，其余判断全是错的，一点边都不沾，还流体，那么两边明明没有端面流体怎么动。

百度文心5.0大模型的识别

这幅图展示的薄壁圆柱件的成型工艺是旋压成形（Spinning）。
旋压成形是一种通过旋压轮对高速旋转的坯料施加压力，使坯料逐点连续塑性变形，从而形成薄壁回转体零件（如圆柱、圆锥、半球等形状）的塑性加工工艺。图中能观察到坯料的旋转运动（箭头示意旋转）以及旋压轮（或类似成形工具）的进给/施压动作（黑色箭头示意进给方向），这些是旋压工艺的典型特征——依靠旋转坯料与成形工具的相对运动，实现薄壁件的逐点塑性成形。

若图中凸型是局部非轴对称凸包、轴向分段凸条等非圆周连续结构，旋压无法实现。百度大模型都没描述出图中谁是要成型的零件，谁是模具，哪个部分是最终成型，就敢判断是旋压工艺啊。

这一追问，好嘛，直接把要加工的零件10'给当成型工具，102给当成待加工的坯料，101是最终成型，离大谱了。

Based on the visual evidence in the diagram, the forming process shown is Necking (specifically Spinning or Shear Spinning used for necking).
Here is a breakdown of the process shown:
Process Name: Necking (often referred to as Spinning when performed with a roller).
Key Elements:
Workpiece (10'): A thin-walled cylindrical part (like a tube or can).
Tool (102): A forming roller that rotates and applies pressure.
Support (101): An internal mandrel or chuck that supports the workpiece during deformation.
Mechanism: The cylindrical part is rotated (indicated by the curved arrow on the mandrel). The roller (102) moves radially inward (indicated by the straight arrow) to apply localized pressure. This causes the metal to flow inward, effectively reducing the diameter of the cylinder in that specific section.
Application: This process is commonly used in manufacturing to create reduced diameters on ends of parts (like the top of a beverage can or a gas cylinder) or to create grooves and structural features in tubular parts.
In summary, the image depicts a necking operation performed via a spinning technique, where a roller radially compresses a rotating thin-walled cylinder to reduce its diameter.

好，开头描述的还可以，中间这块就错了圆筒形工件随芯棒旋转，这个就判断错了，那个弯曲箭头代表的是芯棒及凸滚轮旋转。还有最后判断不对，成形明明是往从内向外压，凸出来的，gemini给理解反了，理解成从外向里压凹进去的，所以才说那直径变小。

直接把零件模具都给识别成工序，你就知道错的有多离谱了。

Upon closer examination of the diagram, it depicts a backward flow forming process (a variant of spinning, also known as tube spinning or shear forming for cylindrical geometries). This is evident from the rotational motion indicated, the localized deformation under the tool, and the material flow direction opposite to what would be the roller's feed path—standard for producing precision thin-walled cylindrical components like tubes or pressure vessels.
To address your points directly:

Identification of components:
The horizontal cylindrical structure is the workpiece (the preform tube being formed).
Label 102 points to the mandrel (the internal mold or support around which the workpiece rotates and is shaped).
Label 101 points to the roller (the external forming tool that applies localized pressure to thin the wall and elongate the material).
The final formed part is the thinned, elongated section of the tube to the right of the roller contact point, with reduced wall thickness compared to the original preform on the left.
The 10' label: This likely indicates the attack angle (or rake angle) of the roller, set at 10 degrees, which is common in flow forming to control shear and material flow without excessive force or defects.
Rotation and flow arrows: The curved arrow on the left shows the direction of rotation for the mandrel and workpiece. The straight arrow inside the tube points to the material flow direction (backward, accumulating material opposite the roller's axial feed).
Regarding non-axisymmetric or segmented convex shapes: While standard spinning processes indeed cannot produce non-rotational-symmetric features (like local bulges or axial strips that break symmetry, as they rely on continuous rotation), the diagram here clearly shows an axisymmetric cylindrical geometry. The "convex shape" appears to refer to the rounded profile of the roller itself, which is typical and fully compatible with spinning for symmetric parts. If the intent was to form a non-symmetric convex hull or strip, a different process like hydroforming or incremental sheet forming would be needed—but that's not what's illustrated.

标号10'明明指向待加工的薄壁筒零件 ，硬给理解成滚轮的切入角（或称前角），设定为10度，就知道这判断全错了。
