有些实施例中： 所述的两个侧面上均设有导折凹槽， 且一个侧面上的导折 凹槽与另一个侧面上的导折凹槽相对。利用相对的导折凹槽去除由磨损而遗留的 根部会更省力。
另一些实施例中： 所述的导折凹槽在两个侧面上沿纵向分段错开分布且 一个侧面上的每一分段的两端分别与另一个侧面上对应分段的端头有重叠 ^域。 也可利用这种导折凹槽的结构去除由磨损而遗留的根部， 达到省力的目的。
一种优化的结构是： 所述两个安装孔远离下底面而靠近上顶面； 所述侧面 上的导折凹槽有多条且相互平行。这样，在加工的过程中可及时地去除由磨损而 遗留的根部，使工作面整体向上凹的程度控制在较小的范围内，有效地控制加工 阻力。两个安装孔远离下底面而靠近上顶面，可在下底面与两个安装孔之间容纳 多条导折凹槽， 并使得去除上述根部的锯条的使用寿命得到延长。
另一种优化的结构是： 所述的两个侧面上位于两个安装孔之间各设置多条 竖立的导砂槽且一个侧面上的导砂槽与另一个侧面上的导砂槽相互错开。这些导 砂槽将有利于切屑的排出， 减小加工阻力和锯条的磨损， 延长锯条的使用寿命。
再一种优化的结构是：所述导折凹槽的两端靠近对应的安装孔各设一条从导 折凹槽到下底面的斜导折凹槽。斜导折凹槽与导折凹槽配合，会使去除由磨损而 遗留的根部的操作更省力。 本发明石材锯条，在至少一个侧面上靠近下底面设置与下底面平行且从一个 端面向另一个端面延伸的导折凹槽。利用导折凹槽，使用扳手之类的简单工具夹 住锯条上由磨损而遗留的根部相对导折凹槽翻折，就可使该根部沿该导折凹槽从 锯条上断裂下来；而不必使用气割枪。利用两个侧面上设置相对的导折凹槽或在 两个侧面上沿纵向分段错开分布的导折凹槽以及斜导折凹槽等措施，使去除由磨 损而遗留的根部的操作会更省力。两个安装孔远离下底面而靠近上顶面，在下底 面与两个安装孔之间容纳多条导折凹槽，使工作面整体向上凹的程度控制在较小 的范围内， 有效地控制加工阻力并使得去除上述根部的锯条的使用寿命得到延 长。在两个侧面上设置导砂槽，减小加工阻力和锯条的磨损，延长锯条的使用寿 命。 因此本发明石材锯条， 具有生产效率高， 消耗量小的优点， 可为石材加工者 带来明显的经济效益。 附图说明

一、 实施例一 本发明石材锯条一个较佳实施例的立体结构， 如图 2所示。 该石材锯条呈 纵向延伸的矩形长条状， 有前后相对的纵向前侧面 10和后侧面 10' , 纵向延伸 且上下相对的上顶面 20和下底面 20' , 左右相对的左端面 30和右端面 30 '。 它 的位于图 2所示下方的下底面 20 ' 为工作面， 上方的上顶面 20为非工作面。 它 的纵向两端处各有一个贯穿前后两个侧面 10、 10' 的安装孔 40; 两个安装孔 40 远离作为工作面的下底面 20 '而靠近作为非工作面的上顶面 20。前侧面 10上靠 近作为工作面的下底面 20' 间隔地设置三条与下底面 20 ' 平行且从左端面 30 向右端面 30 '延伸的导折凹槽 61、 62、 63。导折凹槽 63的两端靠近对应的安装 孔 40各设一条从导折凹槽 63到下底面 20' 的斜导折凹槽 90。后侧面 10 ' 上与 前侧面 10' —一对应， 位置上布置导折凹槽 61、 62、 63和斜导折凹槽（图中未 示出）。
在切割石材的加工过程中， 在工作面与石材之间添加颗粒状硬质的磨削材 料，纵向往复拉动该锯条， 带动磨削材料切割石材。但是磨削材料也同时会造成 锯条工作面的磨损，使工作面由平面逐渐向上凹变成图 2中虚线所示的弧面 51 ; 随着弧面 51的弧线增大，加工的阻力也愈来愈大；当弧面 51的弧线达到引起加 工困难时， 就可使用扳手依次夹住该锯条上由磨损而残留的与弧面 51相邻的两 个根部 71沿导折凹槽 61和斜导折凹槽 90翻折； 使其从锯条上断裂下来； 使加 工面整体向上凹的程度控制在较小的范围内，有效地控制了加工阻力。当工作面 逐渐向上凹变成图 2中虚线所示的弧面 52时， 再次使用扳手依次夹住该锯条上 由磨损而遗留的与弧面 52相邻的两个根部 72沿斜导折凹槽 90和导折凹槽 62 翻折， 就可分别使两个根部 72从锯条上断裂下来； 使工作面整体向上凹的程度 再次控制在较小的范围内，再次有效地控制了加工阻力。当工作面逐渐向上凹变 成图 2中虚线所示的弧面 53; 再使用扳手依次夹住该锯条上由磨损而遗留的与 弧面 53相邻的两个根部 73沿斜导折凹槽 90和导折凹槽 63翻折,分别使该根部
73从锯条上断裂下来； 又一次使加工面整体向上凹的程度控制在较小的范围内， 有效地控制了加工阻力。当工作面逐渐向上凹使锯条最弱横截面抗拉强度趋不安 全， 成图 2中虚线所示的弧面 54时， 则该锯条将不能继续使用。
请注意， 两个安装孔 40远离作为原始工作面的下底面 20' 而靠近作为非 工作面的上顶面 20， 因此本实施例可在作为原始工作面的下底面 20 ' 与两个安 装孔 40之间， 在前侧面 10上容纳多条导折凹槽 61- 63、 在后侧面 10 ' 上容纳 多条导折凹槽 61 ' - 63 '， 并使得去除上述根部 71、 72、 73的锯条的使用寿命 得到延长。
斜导折凹槽 90与各导折凹槽配合， 会使去除由磨损而遗留的根部的操作更 省力。 当然， 斜导折凹槽 90也可开成与各导折凹槽垂直的直槽。 各导折凹槽可 以是在轧机热轧制造本实施例的锯条的过程中直接成型的， 亦可以在冷态下成 型， 斜导折凹槽 90则是冷态下在土冲压出来的。 二、 实施例二 本发明石材锯条第二个实施例的立体结构，如图 3所示。该石材锯条呈纵向 延伸的矩形长条状， 有前后相对的纵向前侧面 110和后侧面 110'， 上下相对的 纵向上顶面 120和下底面 120 '， 左右相对的左端面 130和右端面 130 '。 该石材 锯条下方的纵向下底面 120 ' 为加工面， 上方的上顶面 120为非加工面。 该石材 锯条的纵向两端处各有一个贯穿前后两个侧面 110、 110' 的安装孔 140。两个安 装孔 140远离下底面 120 ' 而靠近上顶面 120。 前侧面 110上靠近下底面 120 ' 间隔地设置两条与下底面 120 ' 平行且从左端面 130向右端面 130 ' 延伸的导折 凹槽 161、 162。 前侧面 110上位于两个安装孔 140之间各设置多条竖立的导砂 槽 170。后侧面 110 '上位于两个安装孔 140之间各设置多条竖立的导砂槽 170 '。 前侧面 110上的各导砂槽 170与后侧面 110 ' 上的各导砂槽 170' 相互错开。 前 侧面 110上导折凹槽 162的两端靠近对应的安装孔 140各设一条从导折凹槽 160 到下底面 120 ' 的斜导折凹槽 190。 这些导砂槽 170将锯条上的导折凹槽 161、 162划分成多段。
在切割石材的加工过程中加工面由平面逐渐向上凹后，使用扳手依次夹住锯 条上由磨损而遗留的根部的各段借助于斜导折凹槽 190相对导折凹槽 161翻折， 分别使该根部的各段沿导折凹槽 161和斜导折凹槽 190从锯条上断裂下来;使加 工面整体向上凹的程度控制在较小的范围内。继续加工过程，在加工面再次逐渐 向上凹严重后，再使用扳手依次夹住锯条上由磨损而遗留的根部的各段借助于斜 导折凹槽 190和导折凹槽 162分割导折作用，可使该根部的各段沿导折凹槽 162 和斜导折凹槽 190从锯条上断裂下来， 再次减小加工面整体向上凹的程度。 三、 实施例三 本发明石材锯条第三个实施例的立体结构，如图 4所示。该石材锯条呈纵向 延伸的矩形长条状， 有前后相对的纵向前侧面 210和后侧面 210' , 上下相对的 纵向上顶面 220和下底面 220'， 左右相对的左端面 230和有端面 230'。 该石材 锯条下方的纵向下底面 220' 为工作面， 上方的上顶面 220为非工作面。该石材 锯条的纵向两端处各有一个贯穿前后两个侧面 210、 210' 的安装孔 240。两个安 装孔 240远离下底面 220' 而靠近上顶面 220。 前侧面 210上靠近下底面 220' 设置三条与下底面 220'平行且从左端面 230向右端面 230'延伸的导折凹槽 261、 262、 263。导折凹槽 263的两端靠近对应的安装孔 240各设一条从导折凹槽 263 到下底面 220' 的斜导折凹槽 290。 前侧面 210上位于两个安装孔 240之间设置 多条竖立的导砂槽 270。前侧面 210上这些导砂槽 270将锯条上的导折凹槽 261、 262、 263划分成多段。 后侧面 210' 上靠近下底面 220' 间隔地设置三条与下底 面 220'平行且从左端面 230向右端面 230'延伸的导折凹槽 261 '、 262'、 263 Ό 其中导折凹槽 263' 的两端靠近对应的安装孔 240各设一条从导折凹槽 263' 到 下底面 220' 的斜导折凹槽（图 4中未示出）。 前侧面 210上的导折凹槽 261与 后侧面 210' 上的导折凹槽 26 相对； 前侧面 210上的导折凹槽 262与后侧面 210'上的导折凹槽 262' 相对； 前侧面 210上的导折凹槽 263与后侧面 210' 上 的导折凹槽 263' 相对。 前侧面 210上的两个导折凹槽 290分别与后侧面 210 ' 上对应的斜导折凹槽相对。 后侧面 210' 上位于两个安装孔 240之间设置多条与 前横向宽端面 210上各纵向导砂槽 270相互错开的竖立的导砂槽 270'。 这些导 砂槽 270' 将锯条上的导折凹槽 26 、 262 '、 263 ' 划分成多段。
在切割石材的加工过程中工作面由平面逐渐向上凹后，使用扳手依次夹住锯 条上由磨损而遗留的根部的各段沿斜导折凹槽 290和导折凹槽 261翻折，就可分 别使该根部的各段沿导折凹槽 261和斜导折凹槽 290从锯条上断裂下来;减小工 作面整体向上凹的程度。继续加工生产，在加工面逐渐向上凹严重后，使用扳手 依次夹住鋸条上由磨损而遗留的根部的各段沿斜导折凹槽 290和导折凹槽 262 翻折,就可分别使该根部的各段沿导折凹槽 262和斜导折凹槽 290从锯条上断裂 下来，再次减小了加工面整体向上凹的程度。继续加工生产，在加工面逐渐向上 凹严重后，再使用扳手依次夹住锯条上由磨损而遗留的根部的各段沿斜导折凹槽 290和导折凹槽 263翻折，就可分别使该根部的各段沿导折凹槽 263和斜导折凹 槽 290从锯条上断裂下来，再次减小了加工面整体向上凹的程度。由于本实施例 采用了双面配合的导折凹槽 261 - 263、 261 ' - 263 ' 和双面配合的各斜导折凹 槽， 非常便于翻折去除根部。 四、 实施例四 本发明石材锯条第四个实施例的前后两个侧面的对比结构， 如图 5所示。 该石材锯条呈纵向延伸的矩形长条状， 有前后相对的纵向前侧面 310和后侧面 310'， 上下相对的纵向上顶面 320和下底面 320' , 左右相对的左端面 330和右 端面 330'。 该石材锯条下方的下底面 320' 为工作面， 上方的上顶面 320为工 作面。 该石材锯条的纵向两端处各有一个贯穿前后两个侧面 310、 310' 的安装 孔 340。 两个安装孔 340远离下底面 320' 而靠近上顶面 320。 前侧面 310上位 于两个安装孔 340之间设置多条竖立的导砂槽 370。后侧面 310'上位于两个安 装孔 340之间设置多条与前侧面 310上各导砂槽 370相互错开的竖立的导砂槽 370'。在前侧面 310和后侧面 310'上从靠近下底面开始设置三条从左端面 330 向右端面 330' 延伸的导折凹槽 361、 362、 363, 这三条导折凹槽 361、 362、 363在前后两个侧面 310、 310'上高度相同沿纵向分段错开分布且在前侧面 310 上的每一分段 L的两端分别与后侧面 310'上对应分段 L'的端头有重叠区域 C。 前侧面 310上导折凹槽 363的两端靠近对应的安装孔 340各设一条从导折凹槽 363到下底面 320' 的斜导折凹槽 390。后侧面 310 '上导折凹槽 363的两端靠近 对应的安装孔 340各设一条从导折凹槽 363到下底面 320' 的斜导折凹槽 390'。 前侧面 310上的两个斜导折凹槽 390分别和后侧面 310'位置上对应的斜导折凹 槽 390' 相对应。
在切割石材的加工过程中加工面由平面逐渐向上凹后，使用扳手依次夹住锯 条上由磨损而遗留的根部的各段沿斜导折凹槽 390和导折凹槽 361翻折，就可分 别使该根部的各段沿导折凹槽 361和斜导折凹槽 390从锯条上断裂下来；减小加 工面整体向上凹的程度。继续加工生产，在加工面逐渐向上凹严重后，使用扳手 依次夹住锯条上由磨损而遗留的根部的各段沿斜导折凹槽 390和导折凹槽 362 翻折，分别使该根部的各段沿导折凹槽 362和斜导折凹槽 390从锯条上断裂下来， 再次减小了加工面整体向上凹的程度。继续加工生产，在加工面逐渐向上凹严重 后，再次使用扳手依次夹住锯条上由磨损而遗留的根部的各段沿斜导折凹槽 390 和导折凹槽 363翻折， 就可分别使该根部的各段沿导折凹槽 263和斜导折凹槽 390从锯条上断裂下来， 再次减小了加工面整体向上凹的程度。 由于本实施例采 用了双面交错配合的导折凹槽 361、362、363和双面配合的斜导折凹槽 390、390' , 也便于翻折去除根部。前侧面 310上各条导折凹槽 361、 362、 363的每一分段 L 的两端与后侧面 310' 上对应分段 L' 的端头之间的重叠区域 C可利于翻折时断 裂线的衔接。 以上所述，仅为本发明较佳实施例， 不以此限定本发明实施的范围，依本发 明的技术方案及说明书内容所作的等效变化与修饰， 皆应属于本发明涵盖的范 围。 工业实用性
