发明有鉴于单向锯切的锯片在鋸刃磨损时即丢弃， 过于浪费， 乃提供一种 可换锯条的圆锯片， 使整体锯片的使用寿限提高一倍。兹列举实施例， 配合图 式， 详述本发明的构造及功效。
请参阅图 1、 图 2所示本发明实施例的外观图与分解图。 本发明所揭示的 可更换锯条的圆锯片 1， 其为一种组装在电锯装置 （图上未示出） 上使用的圆 锯片 1。 该圆锯片 1包含： 一能够固定在电锯装置上由电锯装置驱动旋转的锯 片本体 10、 至少两片能够与锯片本体拼接的弧形锯条 20、 以及多个用来锁固 锯片本体 10与弧形锯条 20之间的螺钉 30。
该锯片本体 10为圆形片状， 其周缘设置有多个凹口 11。 该锯片本体 10 的圆周面设置有一圈沿圆周延伸的凹沟 12。 请参阅图 3。 该凹沟 12可设置在 该锯片本体 10的圆周端面上， 且构成具有两侧壁面 13、 14的凹沟 12。 该凹 沟 12的一侧壁面 13设置有多个螺孔 131， 另一侧壁面 14以相对各螺孔 131 的位置设置有多个穿孔 141。
该各弧形锯条 20的外圆设置有锯齿 21， 且各弧形锯条 20能够相互拼接 成为一完整的环形。 该锯齿 21上设置有锯刃 22. (刀头） ， 能够锯切工作件。 该弧形锯条 20的内缘设置至少一个凸部 23， 该凸部 23能够与锯片本体 10的 凹口 11作一对一的吻合拼合。该弧形锯条 20的内缘设置有一圈沿内缘延伸的 凸片 24， 该凸片 24能够与该锯片本体 10的凹沟 12插合。 该凸片 24上对应 该锯片本体 10的各螺孔 131处设置有多个穿孔 241。 该螺钉 30能够贯穿该锯 片本体 10上的穿孔 141与该凸片 24的穿孔 241， 并锁入该锯片本体 10的螺 孔 131内， 而将各弧形锯条 20锁固在锯片本体 10的周缘。 该锯片本体 10的 凹沟 12的一侧壁面 14上的穿孔 141孔径为扩孔状。该扩孔状的穿孔 141能够 容许该螺钉 30的锥状头部沉入。
前述的各弧形锯条 20在分别组装在该锯片本体 10 内后， 可在锯片本体
10上合围成一完整的环状。 其间， 凭借弧形锯条 20的凸部 23与锯片本体 10 的凹口 11吻合嵌合， 以及螺钉 30所提供锁固作用， 使弧形锯条 20能够与锯 片本体 10—体连动。 同时， 该弧形锯条 20的锯齿 21的锯刃 22成为圆锯片 1 的锯刃 22。 当电锯装置驱动该锯片本体 10转动时， 该锯片本体 10与各弧形 锯条 20即一体连动， 对工作件进行锯切工作。
本发明所提供可更换锯条的结构运用在具有双向锯刃的圆锯片 2上，更能 彰显节省的功效。 请参阅图 4、 图 5及图 6所示本发明另一实施例的外观图与 分解图。具有双向锯刃的圆锯片 2包含：一能够固定在电锯装置上由电锯装置 驱动旋转的锯片本体 40、 至少两片能够与锯片本体拼接的弧形锯条 50、 以及 多个用已锁固锯片本体 40与弧形锯条 50之间的螺钉 60。 其中， 该锯片本体 40设置有与图 2所示锯片本体 10上相同的凹口 41、 凹沟 42、两侧壁 43、 44、 螺孔 431、 穿孔 441等结构。 该弧形锯片 50设置有与图 2所示弧形锯片 20上 相同的凸部 53、 凸片 54、 穿孔 541等结构。 该螺钉 60可将该弧形锯片 50与 锯片本体 40锁固成一体， 且该各弧形锯条 50可在锯片本体 40上合围成一完 整的环状。
该弧形锯片 50沿边缘设置呈突出状且为等角度间隔排列的锯齿 51， 每一 锯齿的前、 后各固设一锯刃 52、 55。 当电锯装置驱动该圆锯片 2旋转时， 该 锯齿 51前缘 （以圆锯片旋转的方向而论， 指锯齿先触及工作件的部位） 的锯 刃 52可对工作件进行锯切， 该锯齿 52后缘的锯刃 55不对工作件锯切。 在使 用一段时间后， 该锯齿 51前缘的锯刃 52发生磨损而不堪使用时， 该锯齿 51 后缘的锯刃 55保持未磨损的锐利状。此时， 可将各弧形锯条 50拆下， 并翻转 180。 重新组装在锯片本体 40上，即可令锯齿 51后缘的锯刃 55转向成为朝前 状态， 锯齿 51前缘的锯刃 52转向成为朝后状态， 而可以该锯刃 55进行锯切 工作件的工作。 如此可更进一步增加弧形锯条 50的使用寿限。 如此， 无须使 用具有正、 反转功能的电锯装置， 就能令圆锯片 2的双向锯刃 52、 55分别作 鋸切工作。
请参阅图 7。前述具有双向锯刃的圆锯片 2可组装在一种可传动双锯片互 做反向旋转的电锯装置（图上未示出）上使用。其中另一圆锯片 3与该圆锯片 2的结构相同，仅螺钉 60' 、 60的锁合位置不同。该电锯装置上的二个锯片 2、 3必须适当的间距， 才能避免二个圆锯片 2、 3的鋸刃 52、 52 ' 相互摩擦， 避 免锯刃 52、 52 ' 损坏， 以及避免锯刃 52、 52' 过热软化变形， 影响切削精度。 圆锯片 2、 3上的螺钉 60、 60' 的末端突出该锯片本体 40、 40' 有 0.25mm的 长度， 且该螺钉 60、 60' 的凸出端与另一圆锯片 3、 2的锯片本体 40' 、 40 接触， 使该二圆锯片 2、 3保有最佳的间距 （二圆锯片 2、 3的锯刃 52、 52' 间距为 0.03mm) 。 其间， 为了避免二圆锯片 2、 3的螺钉 60、 60' 相互触碰， 该二圆锯片 2、 3上的螺钉 60、 60' 位置与二圆锯片 2、 3旋转轴心的距离不 相等， 而呈上、 下错开状。 图 7中附图标记 50' 所指示的元件为弧形锯条。
综上所陈，本发明所提供的可更换锯条的圆锯片， 可凭借更换弧形锯条的 方式， 使圆锯片上的锯刃为崭新状， 而能够提供锯切工作件的功能。 因此， 可 降低耗材成本，让消费者减少支出。本发明结构用于具有双向锯刃的圆锯片上， 更能加倍的延长弧形锯条的使用寿限， 是为一理想而又实用的设计。
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情 况下， 熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但 这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 工业应用性
