Description

一种金刚石链锯及成型方法 技术领域
本发明公开一种金刚石链锯及成型方法，按国际专利分类表(IPC)划分属于金刚石切割工具技术领域。
背景技术
现有花岗石荒料大板，使用金刚石绳锯(单条或者多条组合)来加工切割，在切割时，金刚石绳锯通过二个转动轮或者四个转动轮转动，实现垂直或水平切割。转动轮安装在机架上，整个机架向下移，则为垂直切割，整个机架若水平移动，则为水平切割。但由于金刚石绳锯切割效率较低，且绳锯串珠的金刚石工作层只有1.5毫米左右，因此成本较高，影响它的使用范围。
发明内容
针对现有技术的不足，本发明提供一种金刚石链锯，具有切割效率高、使用范围广、成本低等优点。
为达到上述目的，本发明是通过以下技术方案实现的：
一种金刚石链锯，包括若干链节，链锯的每一节为一体式的链节，链节与链节通过两端的凸出部位与凹入部位相连，金刚石刀头焊接在链节的中部。
进一步，金刚石刀头的排布是连续排布在链锯的每一个链节上或间隔排布在对应链节上。
进一步，链节与链节的凸出部位与凹入部位通过销轴固定相连，销轴两侧与链节平整。
进一步，销轴与链节对应的销孔用焊接的方法固定或销轴两端塑性变形而固定连接。
进一步，链节凸出部位两侧为限位面，该链节为第一链节，相连接的另一链节为第二链节，第二链节的凹入部位具有两侧片，两侧片前端面包括圆弧面和平面，第二链节的平面与第一链节的限位面形成互为直角面的限位结构。
进一步，链锯的总厚度为3mm至7mm。
进一步，链锯配合挂在二个以上数量的转动轮上，转动轮与链条的接触部位是嵌在转动轮外缘开口槽的橡胶条。
本发明还提供一种金刚石链锯的成型方法。
一种金刚石链锯的成型方法，将钢板通过线切割工艺，制成链节，将50目金刚石刀头底部通过高频焊机、使用银焊片焊接到链节中部，然后，将每节链节连接起来，是将链节凸端装入另一链节凹端中，再装上连接销轴用氩弧焊工艺或销轴两端塑性变形固定，便成为整条金刚石链锯。
一种金刚石链锯的成型方法，将合金粉末通过粉末冶金工艺MIM，制成一体式链节，将单个链节放入已经石墨磨具中，将金刚石刀头直接热压到链节上，脱模后，将若干链节装配连接是用销轴装入链节对应孔，然后向销轴施加压力，让销轴的两端塑性变形，填满链节孔外侧的倒角部位，形成整条金刚石链锯。
本发明中链节是一体式结构，没有外链片和内链片，具有如下有益效果：
1、本发明链片的中部为实心结构设计，此中部是与金刚石刀头焊接的部位，链条的抗拉强度增加、链条不易偏摆，链片中部与刀头接触面大，与转动轮摩擦力大、不打滑。
2、本发明链锯制造成本低，焊接在链锯上的刀头，其工作层厚度可达到6毫米左右，降低了切割生产成本。
3、本发明链锯在工作时，由于链条的刚性比绳锯强，不易弯曲，因此切割效率高。

具体实施方式
下面结合附图对本发明作进一步说明：
实施例：请参阅图1至图14，一种金刚石链锯，包括若干链节100，链锯每一节为一体式的链节100，链节与链节通过两端的凸出部位与凹入部位相连，凸出部位与凹入部位也称为链节的凸端3或凹端2，金刚石刀头5焊接在链节的中部1。金刚石刀头5的排布是连续排布在链锯的每一个链节上或间隔排布在对应链节上。链节与链节的凸出部位与凹入部位设有链节连接孔4以供销轴10穿设固定相连，销轴10两侧与链节外表面平整。销轴10与链片对应的销孔用焊接的方法固定或销轴两端塑性变形而固定连接。链节凸出部位(凸端3)两侧为限位面，该链节为第一链节，相连接的另一链节为第二链节，第二链节的凹入部位具有两侧片，两侧片前端面包括圆弧面和平面，第二链节的平面与第一链节的限位面形成互为直角面的限位结构。链锯的总厚度可控制在3mm至7mm。如图11至图14，链锯配合挂在二个以上数量的转动轮6上，转动轮与链条的接触部位是嵌在转动轮外缘开口槽的橡胶条13。
一种金刚石链锯的成型方法，将钢板通过线切割工艺，制成链节，将50目金刚石刀头底部通过高频焊机、使用银焊片焊接到链节中部，然后，将每节链节连接起来，是将链节凸端装入另一链节凹端中，再装上连接销轴用氩弧焊工 艺或销轴两端塑性变形固定，便成为整条金刚石链锯。
本发明链节还可以采用金属粉末注射成形MIM生产，一种金刚石链锯的成型方法，将合金粉末通过粉末冶金工艺MIM，制成一体式链节，将单个链节放入已经石墨磨具中，将金刚石刀头直接热压到链节上，脱模后，将若干链节装配连接是用销轴装入链节对应孔，然后向销轴施加压力，让销轴的两端塑性变形，填满链节孔外侧的倒角部位，形成整条金刚石链锯。
本发明中链节也称为链片，轮动轮也可简称为轮子或链轮。
一种金刚石链锯，节与节连接起来后成为链锯整体，节与节的连接是通过两端的凸出部位与凹入部位相连，通过销轴10固定起来。金刚石刀头5焊接在每一节的中间位置即链节中部实体上，每条链锯上，金刚石刀头的排布可以是连续排布在每一个链节上，也可以间隔排布在每一个链节上。金刚石链锯的链节的销轴两侧与链片平整，用焊接的方法固定或两侧销轴两端塑性变形而固定。链条的总厚度3mm至7mm左右。链条可以挂在二个以上数量的链轮上。链条可挂在二个以上数量的轮子上，链条与轮子的接触部位是嵌在轮子外缘的橡胶条。
本发明设计了一种金刚石链锯，其链条没有外链片和内链片，链条的每一节为一片，也称链节，节与节连接起来后成为链条，节与节的连接是通过两端的凸出部位与凹入部位相连，通过销轴固定起来。金刚石刀头焊接在每一节的中间位置，每条链锯上，金刚石刀头的排布可以是连续排布在每一个链节上，也可以间隔排布在每一个链节上。金刚石刀头工作层厚度可达6毫米左右，金刚石链锯，其连接的销轴两侧与链片平整，用焊接的方法固定，也可以采取销轴两端塑性变形，使之二端外径变得略大一点，与链片孔外侧的倒角相配合，可填充于销孔两侧的倒角边12处，从而使链片固定起来。
由于链片的独特设计，特别是链片的中部为实心设计，有以下优点：1、使 得链条的抗拉强度增加了，保证在切割石材时，链条的拉力足够大而使链条不易偏摆；2、中部平面与金刚石刀头的底部平面接触面积大，焊接时刀头与链片或链节的焊接强度大，链锯切割工作时，刀头不易脱落；3、由于中部为实心设计，在与轮子接触面，摩擦系数大，链锯不需要链轮，而链锯与轮子外缘的橡胶垫接触时不会打滑，保证了链条的正常工作状态；4由于链片结实，使得将链片变薄成为可能，例如总厚度可变为3-5毫米时，焊在其链片或链节上的刀头就可制成3.5-5.5毫米厚，这样由于切缝小，可以用来切割名贵花岗岩薄板，解决了长期以来切割名贵花岗岩薄板的困难，即切缝大，名贵石材的荒料浪费严重的问题。
其次，链锯制造成本低，焊接在链锯上的刀头，其工作层厚度可达到6毫米左右，降低了切割生产成本。
再次，链锯在工作时，由于链条的刚性比绳锯强，不易弯曲，因此切割效率高。
为了增加链片的功能，在设计链片形状时，也可以作些改变，例如为了提高链条的稳定性，增强链片与链片的接触面积，采取图4、图5的设计方案，即将链片上下部位与链片外侧平行的方向，将凹入部位(凹端2)、凸出部位(凸端3)与中部1弧面连接起来，这样即提高了链片的强度，又增加了链片的接触面积，使得链锯在切割中不易偏摆。
为了使金刚石链锯在切割时，链锯中部不会拱起来，因此在链片两端的半圆形设计，也可改为上面四分之一圆，下面为直角设计，见图9所示。这样再金刚石链锯切割石材时，由于相邻的二片链片，互为直角，金刚石链锯在切割时，在石材切缝里，便不会往上拱起来成为圆弧形运动轨迹，使得链锯更稳定，不会偏摆。设备不需要对链锯施加太大的张紧力，降低了链锯部件的磨损程度。
本锯锯类似绳锯，可设计安装单条金刚石链锯机，也可设计出安装多条金刚石链锯机，用于石材切割。
实施例1、用厚度2毫米的45#钢板，通过线切割工艺，制成链片或链节形状，见图1或图4，将金刚石刀头5底部通过高频焊机，使用银焊片将含有50目金刚石的金刚石刀头，焊接到链片中部(链节的中部1)上。然后，将每节链片或链节连接起来，也就是将链片凸端3装入链片凹端2中，再装上连接销轴10，并且用氩弧焊工艺，将销轴固定好，便成为整条金刚石链锯7，见图6，将链锯挂到含有二个轮子的设备上，图12、图13，通过张紧装置，将二个轮张紧后，便可以切割石材荒料8，石材荒料位于滑动台9上。
实施例2、通过粉末冶金工艺MIM，制成一种链片形状(图2、图9所示)，将单个链片放入已经订制好的石墨磨具中，将金刚石刀头直接热压到链片上，脱模后，将链片装配起来，用销轴10，装入链片直接孔4中，见图7，销轴两端有凹槽11，然后向销轴施加压力，让销轴10的两端塑性变形，填满链片销孔两侧的倒角12部位，便使金刚石链锯安装好，见图8。然后，将金刚石链锯挂到四轮(图11)或五轮(图14)设备上，便可进行切割。

  5. 根据权利要求1所述的一种金刚石链锯，其特征在于：链节凸出部位两侧为限位面，该链节为第一链节，相连接的另一链节为第二链节，第二链节的凹入部位具有两侧片，两侧片前端面包括圆弧面和平面，第二链节的平面与第一链节的限位面形成互为直角面的限位结构。
  6. 根据权利要求1所述的一种金刚石链锯，其特征在于：链锯的总厚度为3mm至7mm。
  7. 根据权利要求1至6之一所述的一种金刚石链锯，其特征在于：链锯配合挂在二个以上数量的转动轮上，转动轮与链条的接触部位是嵌在转动轮外缘开口槽的橡胶条。
  8. 一种金刚石链锯的成型方法，其特征在于包括如下步骤：将钢板通过线切割工艺，制成链节，将50目金刚石刀头底部通过高频焊机、使用银焊片焊接到链节中部，然后，将每节链节连接起来，是将链节凸端装入另一链节凹端中，再装上连接销轴用氩弧焊工艺或销轴两端塑性变形固定，便成为整条金刚石链锯。
  9. 一种金刚石链锯的成型方法，其特征在于包括如下步骤：将合金粉末通过粉末冶金工艺MIM，制成一体式链节，将单个链节放入已经石墨磨具中，将金刚石刀头直接热压到链节上，脱模后，将若干链节装配连接是用销轴装入链节对应孔，然后向销轴施加压力，让销轴的两端塑性变形，填满链节孔外侧的倒角部位，形成整条金刚石链锯。
