Description

一种分齿型带锯条 技术领域
本发明涉及一种分齿型带锯条，属于锯切技术领域。
背景技术
从硬质合金产品发展来看，目前主要有分齿型和不分齿型硬质合金带锯条两大类。对于绝大多数的工件来说，锯切主要采用分齿型的硬质合金锯条。
分齿型硬质合金锯条从齿形设计上来看，主要有三屑标准型以及多屑型，其中多屑型又有7屑型，11屑型。从切削力的角度来看，多屑型硬质合金在锯切过程中所受切削力要明显低于三屑标准型，而且分屑越多，所受切削力就越小，但是带锯条的生产成本和质量把控也更难。
目前国内的锯床相比之前有非常大的进步，但是总体而言还是属于老旧设备，而且一些简易型的锯床不带背压，因此在使用硬质合金带锯条的过程中，容易出现非常大的振动，锯切声音非常尖锐、刺耳。尤其是采用三屑标准型硬质合金带锯条，由于每组齿数最少，故其固有频率很低，很容易产生共振的现象，因此不但振动大，而且由于共振容易导致锯条的提前失效。
对于多屑型的硬质合金锯条而言，虽然在共振的问题以及切削力的问题上得到很大的改善和提升，但是多屑型的锯条由于每组齿数较多，每组齿中的单个齿的刃口利用程度并不高，即每一单个齿实际起到切削作用的刃口较短，因此对于单个齿而言，起到切削作用的刃口越短，该受力刃口的应力就越大，其刃口就非常容易出现磨损的情况，从而出现锯不动、效率低等情形。
因此，在降低切削力的基础上，如何增加单齿刃口利用率成为多屑型硬质合金带锯条需要解决的技术问题。
发明内容
本发明提供一种分齿型带锯条，一方面是为了解决在锯切工件时由于每组齿数少导致其固有频率低，容易产生振动、尖叫的问题，另一方面是为了解决在锯切过程中单齿磨损过大造成切不动、锯切效率低，容易产生锯斜的问题。具体技术方案如下。
一种分齿型带锯条，包括锯条本体和位于锯条本体上的锯齿，其特征在于，连续分布的7个锯齿形成一个周期，一个周期内7个齿分别为第一锯齿、第二锯齿、第三锯齿、第四锯齿、第五锯齿、第六锯齿、第七锯齿；
分齿前，所述第一锯齿、第三锯齿的顶部向左边倾斜，所述第二锯齿、第四锯齿的顶部 向右边倾斜，所述第五锯齿的顶部两侧具有倒角，所述第六锯齿、第七锯齿的顶部平齐；所述第一锯齿、第二锯齿、第三锯齿、第四锯齿的高度相同，且大于所述第五锯齿的高度；所述第六锯齿和所述第七锯齿的高度相同，所述第五锯齿的高度大于所述第六锯齿的高度；
分齿后，所述第一锯齿、第二锯齿、第五锯齿不分齿，所述第三锯齿、第六锯齿向右边分齿，所述第四锯齿、第七锯齿向左边分齿，其中，所述第三锯齿、第四锯齿的分齿量相同，所述第六锯齿、第七锯齿的分齿量相同，且所述第三锯齿的分齿量小于所述第六锯齿的分齿量；沿着所述锯条本体的延伸方向观察，所述第五锯齿顶部中间平齐部分高于所述第一锯齿的中间部分，也高于所述第二锯齿的中间部分。
进一步地，所述锯齿的前角为10°-20°，优选为10°；锯齿后角为10°-30°，优选20°。
进一步地，分齿前，所述第一锯齿、第五锯齿、第六锯齿的高度呈等差数列分布。优选地，所述第一锯齿比所述第五锯齿高0.07mm，所述第五锯齿比所述第六锯齿高0.07mm。
进一步地，分齿前，所述第一锯齿、第三锯齿的顶部向左边倾斜的角度为θ，所述第二锯齿、第四锯齿的顶部向右边倾斜的角度为θ，角度θ为5°-15°；优选地，角度θ为7°。
进一步地，所述第五锯齿的倒角角度ω为15°-50°；优选为45°。
本发明采用7齿/组的齿形设计，锯切过程中的切屑更加细长且薄，能够进一步降低切削力；通过对各个齿型的设置，充分利用了不同齿的刃口部分的补偿作用，并尽可能地提高每一个齿的刃口利用程度，能够增强整体抗磨损性能，延长齿部的使用寿命。

具体实施方式
下面结合附图对本发明作进一步详细描述。
参见图1-6，一种分齿型带锯条，包括锯条本体和位于锯条本体上的锯齿，其特征在于，连续分布的7个所述锯齿形成一个周期，一个周期内7个齿分别为第一锯齿1、第二锯齿2、第三锯齿3、第四锯齿4、第五锯齿5、第六锯齿6、第七锯齿7；
如图3所示，分齿前，第一锯齿1、第三锯齿3的顶部向左边倾斜，第二锯齿2、第四锯齿4的顶部向右边倾斜，第五锯齿5的顶部两侧具有倒角，第六锯齿6、第七锯齿7的顶部平齐；第一锯齿1、第二锯齿2、第三锯齿3、第四锯齿4的高度相同，由于它们的顶部均是倾斜的，其高度是指最高高度(尖端高度)，且第一锯齿1的高度大于第五锯齿5的高度；第六锯齿6和第七锯齿7的高度相同，第五锯齿5的高度大于第六锯齿6的高度；优选地，第一锯齿1、第五锯齿5、第六锯齿6的高度呈等差数列分布。优选地，第一锯齿1比第五锯齿5高0.07mm，第五锯齿5比所述第六锯齿6高0.07mm；第一锯齿1、第三锯齿3的顶部向左边倾斜的角度为θ，第二锯齿2、第四锯齿4的顶部向左边倾斜的角度为θ，根据锯切材料的不同，θ的角度也不同。一般θ的角度范围为0°～15°，在本实施案例中，由于锯切材料硬度不高，θ在5°～10°，优选7°；5#为两侧倒角，角度为ω，ω一般在15°～50°，在本实施案例中，由于锯切材料较软，因此角度在30°～50°，优选45°。
如图2所示，分齿后(带锯条的锯齿加工好之后会进行分齿加工)，第一锯齿1、第二锯齿2、第五锯齿5不分齿，第三锯齿3、第六锯齿6向右边分齿，第四锯齿4、第七锯齿7向左边分齿，其中，第三锯齿3、第四锯齿4的分齿量相同，第六锯齿6、第七锯齿7的分齿量相同，且第三锯齿3的分齿量小于第六锯齿6的分齿量；沿着锯条本体8的延伸方向观察(如图2所示)，第五锯齿5顶部中间平齐部分高于第一锯齿1的中间部分，也高于第二锯齿2的中间部分。这里的左边和右边是相对而言的，其实质是表示第一锯齿1和第二锯齿2顶部的倾斜方向相反；第三锯齿3和第四锯齿4的分齿方向相反。
锯齿前角α(见图1)在切削过程中主要是对工件的切入性，一般地前角越大，切入性越好；前角的大小能够改善切削力，前角越大，锯齿在切削过程中，所受切削力越小。α的范围一般在-5°～20°，在本实施案例中，由于锯切工件是比较通用型材料，因此前角α为10°～20°，优选为10°；
锯齿后角β(见图1)在切削过程中主要是抗振动能力以及进给方向的切削力。一般地后角越大，抗振动能力越差，进给方向所受切削力越小；另外，后角越大，后刀面与工件之间的摩擦就越小，锯切时切削液能够更好的进入到齿尖与工件之间，散热效果更好，能够更好的降低齿尖的温度，减缓齿尖刃口的磨损。后角β的范围一般在10°～30°，在本实施案例中，由于在进给方向上所受切削力不大，因此后角β为10°～30°，优选20°；
1～7#锯齿产生的切屑见图4所示。其中1#、2#齿所产生的切屑厚度相同，3#、4#齿所产生的切屑厚度相同；6#、7#齿所产生的切屑厚度相同；5#齿产生的切削厚度较厚较窄。
各齿尖刃口见图5-6所示。在锯切过程中，1#～7#齿依次进入工件，1#齿的刃口由L1～L4组成，2#齿的刃口由L5～L8组成，5#齿的刃口为L9。当1#、2#进入工件后，因1#齿 锯切部分已经覆盖2#齿的L7、L8，2#齿的锯切部分已经覆盖1#齿的L3、L4，所以其真正起到锯切作用的是L1、L2以及L5、L6部分的刃口，而当L1、L2以及L5、L6出现磨损过大的情况，则L7、L8以及L3、L4将会对其进行补偿，从而达到延长锯条寿命的效果。同理，5#齿的刃口L9出现过大磨损后，1#、2#齿的刃口部分L2、L3、L6、L7也会对其进行补偿。一方面，可以补偿刃口的磨损(L10、L11)，二是降低3#、4#、6#、7#齿，即左、右偏齿的切削力，从而获得更加光滑的锯切断面。
根据M.Sarwar，H.Hellbergh，A.R.Doraisingam，M.Persson等人发表的论文“Simulation of the Intermittent Cutting Action of a Bandsaw Blade”，我们可以建立相应的锯切过程中切屑厚度与切削力之间的关系，如图7所示，其中方点表示切削力的理论值，圆点表示实际及修正值。
根据切削力与切屑厚度关系，将硬质合金常见齿形的切削力进行计算，并得出各个齿形的切削力，见下表1所示：
表1不同齿行切屑力和切削数的对比表
Figure PCTCN2021108123-appb-000001
从上表格中可以看出，本实施案例中的齿型设计所受切削力是最低的，从整体齿型设计来看，本发明专利相比三屑通用型产品，其切削力要降低17.85％，相比Bacho 3881THQ系列其切削力虽无明显优势，但是其生产加工效率要高。另外，本发明专利中7齿/组，其中中齿占了3齿，占比42.86％(Bacho THQ中齿占比33.33％)，相比上述的分齿型的系列都要高很多，增强了齿部抗磨损的能力，达到了抗切斜的目的。
上面结合附图对本发明的实施例进行了描述，在不冲突的情况下，本发明中的实施例及 实施例中的特征可以相互组合。本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是局限性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护范围之内。
