链锯导板 技术领域  Chain saw guide
本发明属一种链锯导板的技术领域， 尤指一种能避免材料的浪费， 达到成本降 低的目的。 背景技术  The invention belongs to the technical field of a chain saw guide, and particularly relates to a purpose of avoiding waste of materials and achieving cost reduction. Background technique
按， 链锯为一种动力工具， 用于裁切木材或石材， 而链锯主要设置有动力部及 可锁固于动力部的导板， 导板周缘设有链锯导沟， 链锯导沟的目的， 在承受链锯条 的高速、 高压的正常运转， 为提供安全又耐用的导沟， 链锯导板的设计， 由材质、 硬度及方便性， 正发展多种的形式。  According to the chain saw, it is a power tool for cutting wood or stone. The chain saw is mainly provided with a power part and a guide plate that can be locked to the power part. The periphery of the guide plate is provided with a chain saw guide groove, and the chain saw guide groove Purpose, in the high-speed, high-pressure normal operation of the chain saw blade, in order to provide a safe and durable guide groove, the design of the chain saw guide is developed in various forms by material, hardness and convenience.
上述请参阅图 5所示， 链锯 3 0基本上包含有动力部 3 1、 链锯条 3 2、 链锯 导板 3 3，其中该动力部 3 1并具有壳体 3 4包覆，其间并设有握把 3 5提供握持。 链锯导板 3 3供链锯条 3 2导正移动而磨擦，所以链锯导板 3 3的硬度及靭性均需 符合要求， 才不致因链锯条 3 2的摩擦而损坏。  As shown in FIG. 5, the chain saw 30 basically includes a power portion 3 1 , a chain saw blade 3 2 , and a chain saw guide 33 . The power portion 31 has a casing 34 and is disposed therebetween. There is a grip 3 5 to provide grip. Chain saw guide 3 3 for chain saw blade 3 2 guides to move and rub, so the hardness and toughness of the chain saw guide 3 3 must meet the requirements, so as not to be damaged by the friction of the chain saw blade 3 2 .

It needs to withstand extremely high temperatures, which soften the guide groove steel and even damage the guide groove. Therefore, the material used at the forefront of the guide plate is the best with the hardness of STEADITE. Please refer to Figure 6, which includes There is a metal plate 41.

The depth of 4 2 can be deepened, so that the chain saw blade can be engaged, so that the teeth of the chain saw blade can reciprocate along the guiding of the guiding groove, and the object can be cut.
然而， 史帝田铁板材 4 3板材价格很高， 又难切割成所需的形状， 切割太多或 较少时， 都容易浪费材料， 只能用高价的激光加工， 才能达到所需的要求； 且在悍 接史帝田铁板材 4 3时， 易造成偏斜， 导致导沟 4 2的空位形状不正确， 进而使链 锯条高速运转下， 卡死甚至跳脱。  However, the price of the 4th sheet of the Styron sheet metal is very high, and it is difficult to cut into the desired shape. When cutting too much or less, it is easy to waste materials, and only high-priced laser processing can be used to meet the required requirements. And when the 帝 史 田 铁 铁 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4
