带半封闭冷却水槽的同步切割机用组合开槽片 技术领域
本发明涉及切割机领域，具体地指一种带半封闭冷却水槽的同步切割机用组合开槽片。
背景技术
金刚石组合开槽片是一种多片开槽片同轴旋转同步切割的高效切割装置。然而，由于切割作业中钢基体受热影响，尤基体刚性难以保证，同时组合开槽片片的直径越大、切深越深，外部浇水无法进入切缝内部，钢基体发热严重，钢基体的刚性越难以保障，受热影响越明显，使得基体易于变形，切割效率降低、切割寿命下降。如果仅通过增加钢基体的厚度去维持基体的刚性，则大幅增加了钢基体的成本以及设备的功率消耗。
因此，大直径的金刚石组合开槽片而言，冷却问题一直是阻碍其降低成本和提高效率的一大要因。
发明内容
本发明的目的在于，提供一种整体散热冷却效果好的带半封闭冷却水槽的同步切割机用组合开槽片。

作为优选方案，带所述缝隙的所述冷却水槽与不带所述缝隙的冷却水槽在所 述内部夹板上间隔分布。
作为优选方案，每一所述内部夹板上的所述闭冷却水槽的数量与所述外侧金刚石开槽片上的所述冷却水通孔的数量相对应，所述外侧金刚石开槽片上沿同一圆周均匀分布有8个所述冷却水通孔，所述内部夹板上内部夹板上分布有8个所述闭冷却水槽。
作为优选方案，所述闭冷却水槽靠近所述外侧金刚石开槽片的圆心处的端部为圆弧形，所述闭冷却水槽远离所述外侧金刚石开槽片的圆心处的端部为圆弧形，所述缝隙沿所述内部夹板的径向连通所述冷却水槽的远端的所述圆弧形处与所述内部夹板的外圆边缘所述内部夹板。

作为优选方案，所述组合开槽片的直径大于600mm。
本发明的有益效果是：本发明的带半封闭冷却水槽的同步切割机用组合开槽片通过外侧开槽片的冷却水通孔往内部夹板的冷却水槽注水，形成连通的水槽，使其在切割作业中，尤其切缝较深无法通过外部浇水冷却基体时，充分发挥半封闭冷却水槽的持续冷却效果，同时从冷却水槽流出的水可以进一步冷却开槽片外圆的金刚石节块和基体，对组合开槽片的整体进行有效持续散热和冷却，保持钢基体的刚性，提高切割效率和寿命，特别适用于各种高强度、高效率的作业场合。
