Abstract

本发明公开了一种海带切丝刀片。其主要解决现有圆形刀片因前角、楔角设定不合理而存在拉料速度慢且不均速、效率差的问题。其包括一圆片状刀体，在刀体中心开有一轴孔，在刀体的周边上设有若干刀齿，特点是：刀齿的前角角度为0°～10°，楔角角度为35°～50°，齿深为1.0～1.1mm。本发明前角角度设定成正值，拉动海带的受力方向改变，增加了拉力且不会产生打滑；楔角角度设定变小，刀齿可快速深入料体内。本发明拉料速度均匀且快，效率高，适用范围广。

Description

一种海带切丝刀片
技术领域
本发明涉及切割元件，尤其是一种海带切丝刀片。
背景技术
海带切丝加工已实现机械化，海带切丝机得到广泛应用。其主要包括第一刀轴及第二刀轴，在第一刀轴及第二刀轴上间隔安装圆形刀片，该圆形刀片采用陶瓷材料烧结、磨削制成，且圆形刀片周边上均匀设有刀齿，两根刀轴上的刀片相互交错插入，电动机驱动两刀轴带动刀片对向转动，通过圆形刀片上的刀齿实现拉料功能，通过相邻刀片的刀体剪切作用实现切丝功能。例如，2014年1月29日公开的CN203409806U中国实用新型专利说明书中就公开了这样一种结构的海带切丝机。目前，公开使用的海带切丝圆形刀片如图1所示，其刀齿的前角4角度均设定为负值，楔角5角度(约为60°)设定过大。这种结构的圆形刀片，因楔角角度过大造成刀齿进入料体过浅，前角角度设定为负值造成刀齿拉料易出现打滑，尤其是料体较肥厚的海带打滑现象十分明显，其存在着拉料速度慢且不均速、效率差问题。
发明内容
为了克服现有圆形刀片因前角、楔角设定不合理而存在拉料速度慢且不均速、效率差的不足，本发明提供一种设计合理、拉料速度均速且快、效率高、适用范围广的海带切丝刀片。
本发明解决其技术问题所采用的技术方案是：一种海带切丝刀片，其包括一圆片状刀体，在所述的刀体中心开有一轴孔，在刀体的周边上设有若干刀齿，其特征在于：所述的刀齿的前角角度为0°～10°，楔角角度为35°～50°，齿深为1.0～1.1mm。
所述的刀齿的前角角度为4°。
所述的刀齿的楔角角度为45.21°。
所述的刀齿的齿深为1.05mm。
所述的轴孔为一双扁轴孔。
本发明是在圆片状刀体的周边上设有若干刀齿，刀齿的前角角度为0°～10°，楔角角度为35°～50°，齿深为1.0～1.1mm，其楔角角度设定变小，刀齿齿尖变小，可快速深入料体内；前角角度设定成正值，改变了刀齿拉动海带的受力方向，增加了刀齿拉动海带的拉力，其在拉动海带料体时不会产生打滑。本发明与现有海带切丝圆形刀片相比，其拉料速度均匀且快、效率高，尤其适合料体较为肥厚的海带切丝，其适用范围广。
附图说明
下面结合附图和实施例对本发明作进一步说明。
图1是本发明的现有技术的一种结构示意图；
图2是本发明的一种结构示意图；
图3是图1中Ⅰ处的放大视图。
图中标记：1.刀体，2.刀齿，3.轴孔，4.前角，5.楔角，6.齿深。
具体实施方式
实施例一
在图2中，一种海带切丝刀片，其包括一圆片状刀体1，在刀体1的周边上均匀设有若干刀齿2。其中，刀体1选用耐磨、抗腐蚀的陶瓷材料烧结、磨削制成。如图3所示，在本实施例中，刀齿2的前角4角度设定为4°，楔角5角度设定为45.21°，齿深6为1.05mm。
需要说明的是，海带切丝刀片的外径、厚度、轴孔直径等几何参数可根据使用要求设定。
为了刀片的制造工艺及合理装配在刀轴上，如图2所示，在刀体1的中心开有一轴孔3，该轴孔3为双扁轴孔。双扁轴孔的设计，使得圆形刀片烧结过程中不易变形，且传递扭矩均匀，其设计合理。
本实施例中，刀齿2的前角4、楔角5、齿深6的参数设定，是本发明的最佳方案，其刀齿可深入料体内，增加了拉动海带的拉力且不会产生打滑现象，具有拉料速度快且均匀、效率高的优点。
实施例二
本实施例中，一种海带切丝刀片，其包括一圆片状刀体1，在刀体1的周边上均匀设有若干刀齿2。其刀体1与实施例1相同，其不同之处在于：刀齿2的前角4角度设定为0°，楔角5角度设定为49.21°，齿深6为1.0mm。
实施例三
本实施例中，一种海带切丝刀片，其包括一圆片状刀体1，在刀体1的周边上均匀设有若干刀齿2。其刀体1与实施例1相同，其不同之处在于：刀齿2的前角4角度设定为10°，楔角5角度设定为35.21°，齿深6为1.1mm。
