热缩延长杆的工作原理
热缩延长杆的工作原理主要基于热胀冷缩原理。具体来说，它利用了刀柄（通常为特殊不锈钢材质）和刀具（如硬质合金刀具）之间热膨胀系数的差异，通过加热使刀柄膨胀，然后迅速套入刀杆，待其冷却后，刀柄因收缩而紧紧固定住刀具，从而实现精准的延长和固定效果。
详细工作步骤：
1. 加热阶段：将热缩延长杆（刀柄）加热至一定温度，使其内部材料因热膨胀而体积增大。
2. 套入刀杆：在刀柄处于膨胀状态时，迅速将其套入刀杆（或刀具的安装部位）。
3. 冷却固定：待刀柄冷却后，材料因热胀冷缩原理收缩，与刀杆之间产生紧密的锁紧力，从而牢固地固定住刀具。这种固定方式不仅操作简便，而且固定效果非常牢固，完全不用担心在使用过程中会出现松动或脱落的情况。
4. 重复使用：当刀具磨损需要更换时，只需再次加热延长杆，使其膨胀后即可轻松取下旧刀具并安装新刀具，非常方便快捷。
优势：
高精度夹紧：冷却过程中金属均匀收缩，保证与所夹持的刀具具有很大的接触面积，可提供的夹持力几乎相当于整体刀具，超过其他各类刀柄的夹持精度和精度保持能力。
操作简便：无需复杂工具，通过加热和冷却即可完成安装和拆卸。
适用广泛：适用于木工、金属加工、CNC加工等多种场景，能延长工具寿命，提高工作效率。
总之，热缩延长杆通过巧妙利用材料的热胀冷缩特性，实现了对刀具的高精度、高效率固定，是机械加工和手工制作中的实用工具。
The working principle of the heat shrinkage extension rod
The working principle of the heat shrinkage extension rod is mainly based on the principle of thermal expansion and contraction. Specifically, it takes advantage of the difference in the coefficient of thermal expansion between the tool holder (usually made of special stainless steel) and the cutting tool (such as hard alloy cutting tools). By heating, the tool holder expands and then is quickly inserted into the tool shank. After it cools down, the tool holder contracts and tightly fixes the cutting tool, thereby achieving precise extension and fixation effects.
Detailed work steps
1. Heating stage: Heat the heat shrinkage extension rod (tool handle) to a certain temperature, causing the internal material to expand in volume due to thermal expansion.
2. Insert the tool holder: When the tool holder is in an expanded state, quickly insert it into the tool holder (or the installation area of the tool).
3. Cooling and fixation: After the tool holder cools down, the material contracts due to the principle of thermal expansion and contraction, generating a tight locking force between it and the tool shank, thereby firmly fixing the tool. This fixing method is not only easy to operate but also has a very firm fixing effect. There is no need to worry at all about loosening or falling off during use.
4. Reuse: When the tool wears out and needs to be replaced, simply reheat the extension rod to expand it, and then the old tool can be easily removed and a new one installed. It is very convenient and fast.
Advantages
High-precision clamping: During the cooling process, the metal shrinks uniformly, ensuring a large contact area with the clamped tool. The clamping force it can provide is almost equivalent to that of the entire tool, surpassing the clamping accuracy and precision retention capacity of other types of tool holders.
Easy operation: No complex tools are required. Installation and disassembly can be completed simply by heating and cooling.
Wide application: It is suitable for various scenarios such as woodworking, metal processing, and CNC processing, which can extend the service life of tools and improve work efficiency.
In conclusion, the heat shrink extension rod achieves high-precision and high-efficiency fixation of cutting tools by ingeniously utilizing the thermal expansion and contraction characteristics of materials, making it a practical tool in both mechanical processing and manual manufacturing.
