本实用新型的有益效果是：通过在所述的钻头本体上设置螺旋角a逐渐变化的容屑槽，并使所述的容屑槽与所述的引屑槽连通。这样，便可以根据被加工产品的材料特性在钻屑过程中出现的铁屑的变化情况，选择含有不同螺旋角a的容屑槽的钻头进行钻屑，尽量使变形后的铁屑能随容屑槽顺利排出，达到有效提高排屑率，保证排屑通道最大限度畅通的目的。The beneficial effects of the utility model are: by setting chip flutes with gradually changing helix angle a on the drill bit body, and making the chip flutes communicate with the chip introduction flutes. In this way, according to the material characteristics of the processed product and the change of iron filings during the drilling process, drill bits with chip flutes with different helix angles a can be selected for drilling chips, so that the deformed iron filings can be as easily as possible The chip flute is discharged smoothly to effectively improve the chip removal rate and ensure the maximum smoothness of the chip removal channel.
进一步的是，绕所述钻头本体外表面旋转的所述容屑槽的槽侧面与所述钻头本体轴向截面之间的所述螺旋角a逐渐变大。Further, the helix angle a between the flute side of the chip flute that rotates around the outer surface of the drill body and the axial section of the drill body gradually increases.
进一步的是，绕所述钻头本体外表面旋转的所述容屑槽的槽侧面与所述钻头本体轴向截面之间的所述螺旋角a逐渐变小。Further, the helix angle a between the flute side of the chip flute rotating around the outer surface of the drill body and the axial section of the drill body gradually becomes smaller.
进一步的是，所述的钻头本体还包括加强凸台，所述容屑槽的尾端结束于所述的加强凸台中。Further, the drill bit body also includes a reinforcing boss, and the tail end of the chip flute ends in the reinforcing boss.

具体实施方式Detailed ways
如图1所示是本实用新型提供的一种能有效的提高排屑率，保证排屑通道最大限度畅通的便于排屑的钻头。所述的钻头包括设置有引屑槽2的钻头本体1，在所述的钻头本体1上还设置有螺旋角a逐渐变化的容屑槽3，所述的容屑槽3与所述的引屑槽2连通。通过在所述的钻头本体1上设置螺旋角a逐渐变化的容屑槽3，并使所述的容屑槽3与所述的引屑槽2连通。这样，便可以根据被加工产品的材料特性在钻屑过程中出现的铁屑的变化情况，选择含有不同螺旋角a的容屑槽的钻头进行钻屑，尽量使变形后的铁屑能随容屑槽顺利排出，达到有效提高排屑率，保证排屑通道最大限度畅通的目的。As shown in Figure 1, the utility model provides a drill bit that can effectively improve the chip removal rate and ensure the smoothest chip removal channel to facilitate chip removal. The drill bit includes a drill body 1 provided with a chip flute 2, and a chip flute 3 with a gradually changing helix angle a is also provided on the drill body 1, and the chip flute 3 is connected with the guide Chip flute 2 is connected. A chip flute 3 with a gradually changing helix angle a is provided on the drill body 1 , and the chip flute 3 communicates with the chip introduction flute 2 . In this way, according to the material characteristics of the processed product and the change of iron filings during the drilling process, drill bits with chip flutes with different helix angles a can be selected for drilling chips, so that the deformed iron filings can be as easily as possible. The chip flute is discharged smoothly to effectively improve the chip removal rate and ensure the maximum smoothness of the chip removal channel.
上述实施方式中，所述容屑槽3绕所述钻头本体1外表面旋转的螺旋角a可以有两种结构，一种结构是绕所述钻头本体2外表面旋转的所述容屑槽3的槽侧面与所述钻头本体2轴向截面之间的所述螺旋角a逐渐变大，这种结构的钻头用于铁屑5在切除过程中弯曲变形较大的硬度的产品的钻削；另一种结构是绕所述钻头本体2外表面旋转的所述容屑槽3的槽侧面与所述钻头本体2轴向截面之间的所述螺旋角a逐渐变大，这种结构的钻头用于铁屑5在切除过程中弯曲变形较小的硬度的产品的钻削。In the above embodiment, the helix angle a of the chip flute 3 rotating around the outer surface of the drill body 1 can have two structures, one structure is that the chip flute 3 rotates around the outer surface of the drill body 2 The helix angle a between the side of the groove and the axial section of the drill body 2 gradually increases, and the drill with this structure is used for drilling of products with greater hardness and bending deformation of the iron filings 5 during the cutting process; Another structure is that the helix angle a between the groove side of the chip flute 3 that rotates around the outer surface of the drill body 2 and the axial section of the drill body 2 becomes larger gradually. It is used for drilling of products with less bending deformation during the cutting process of iron filings 5.
同时，为了避免排出的铁屑随容屑槽3上升排出时对钻床的旋转轴造成损坏，同时提高钻头的强度，所述的钻头本体1还包括加强凸台4，所述容屑槽3的尾端结束于所述的加强凸台4中。Simultaneously, in order to prevent the discharged iron filings from causing damage to the rotating shaft of the drilling machine when the chip pocket 3 rises and discharges, and at the same time improve the strength of the drill bit, the drill bit body 1 also includes a reinforcing boss 4, and the chip pocket 3 The tail ends in the said reinforcing boss 4 .
