Abstract
Diamond thin wall drill, it has one yuan of pipy barrel, and the lower extreme of barrel has a joint, and the last port border equipartition of barrel has the tool bit more than two, has the medial surface of a tool bit and the medial surface parallel and level of barrel at least, in addition, the medial surface of other each tool bit exceeds the medial surface of barrel. The utility model provides a during diamond thin wall drill holed to the reinforced concrete wall body, the reinforcing bar cutting of drill bit from the wall body in be the reinforcing bar piece down, and cut down reinforcing bar piece salient when the concrete column's that is cut down profile owing to have the medial surface of a tool bit and the medial surface parallel and level of barrel at least, consequently, as long as rotate the barrel, through the adjustment, can be very fast with tool bit with barrel medial surface parallel and level and reinforcing bar block alignment, and then smooth withdrawing from the barrel in the wall body. The utility model discloses rational in infrastructure, use reliably, its is difficult to by the card in the wall body for drilling quality and progress obtain guaranteeing.
Description
Technical field
The utility model relates to drill bit, specifically a kind of diamond thin-wall drill bit for punching on wall.
Background technology
At present, what cement wall is holed employing usually is diamond thin-wall drill bit.Existing diamond thin-wall drill bit basic structure is: the lower end of the cylindrical shell of a circular tube shaped is connected with a joint, and the upper port edge of cylindrical shell is evenly equipped with plural diamond segment, and the medial surface of each cutter head all exceeds the medial surface of cylindrical shell.On existing this drill bit, the medial surface of each cutter head all exceeds the structure of the medial surface of cylindrical shell, is in order to after having holed, drill bit can exit smoothly smoothly from the hole of having bored and the concrete column be cut.But Problems existing is, when the wall body hole to reinforced concrete, owing to containing reinforcing bar in body of wall, drill bit is once get on reinforcing bar and after a part for reinforcing bar being cut down, this part reinforcing bar be cut is subjected to displacement along with the rotation of drill bit, cause the meeting of this part reinforcing bar to protrude from the profile of the concrete column be cut, the medial surface due to each cutter head all exceeds the medial surface of cylindrical shell, and this part reinforcing bar be cut just hinders cylindrical shell to exit from the hole of having bored; Therefore, once there are the problems referred to above in construction, then drill bit can be caused because can not moving back to be trapped in punching failure phenomenon on body of wall, this not only have impact on body of wall attractive in appearance, but also have impact on construction speed, and cause the waste of drill bit.
Utility model content
The purpose of this utility model is to provide a kind of diamond thin-wall drill bit, and this diamond thin-wall drill bit still can exit after being cut to reinforcing bar in reinforced concrete Drilling operation smoothly.
To achieve these goals, the utility model adopts following technical scheme: diamond thin-wall drill bit, it has the cylindrical shell of a circular tube shaped, the lower end of cylindrical shell has a joint, the upper port edge of cylindrical shell is evenly equipped with plural cutter head, have at least the medial surface of a cutter head concordant with the medial surface of cylindrical shell, in addition, the medial surface of other each cutter head exceeds the medial surface of cylindrical shell.
From such scheme, during the diamond thin-wall drill bit adopting the utility model to provide is holed to reinforced concrete body of wall, drill bit is from the lower reinforcing bar block of reinforcing bar cutting in body of wall, and cut down reinforcing bar block when protruding from the profile of the concrete column be cut, because the medial surface of the medial surface with cylindrical shell that have a cutter head at least is concordant, therefore, as long as rotating cylinder, by adjustment, can be very fast by the cutter head concordant with cylindrical shell medial surface and reinforcing bar block alignment, and then smoothly cylindrical shell is exited in body of wall.
The utility model is rational in infrastructure, use is reliable, and it is not easy to be stuck in body of wall, and drilling quality and progress are guaranteed.
Accompanying drawing explanation
The structural representation of Fig. 1 the utility model one embodiment;
The top view of Fig. 2 Fig. 1;
Fig. 3 use principle figure of the present utility model.
Detailed description of the invention
The utility model is further illustrated below in conjunction with embodiment and accompanying drawing.
See Fig. 1, Fig. 2
The diamond thin-wall drill bit that the utility model provides, it has the cylindrical shell 2 of a circular tube shaped, and the lower end of cylindrical shell 2 has a joint 3, and the upper port edge of cylindrical shell 2 is evenly equipped with plural cutter head.In the present embodiment, have the medial surface of a cutter head 1b concordant with the medial surface of cylindrical shell 2, in addition, the medial surface of other each cutter head 1a exceeds the medial surface of cylindrical shell 2.
See Fig. 3
Adopt the diamond thin-wall drill bit that provides of the utility model to when holing with regard to body of wall, owing to there being the medial surface of a cutter head 1b concordant with the medial surface of cylindrical shell 2, therefore after boring completes, between this cutter head 1b and the concrete column 4 that is cut out, there is space 6.When this diamond thin-wall drill bit is holed on reinforced concrete wall, cutter head has encountered reinforcing bar, and cut reinforcing bar block 5, and the reinforcing bar block 5 cut down is when protruding from the profile of the concrete column 4 be cut, the ledge that reinforcing bar is 5 pieces has blocked cutter head 1a corresponding thereto, cylindrical shell 2 cannot be exited, for addressing this problem, rotating cylinder 2, the cutter head 1b concordant with the medial surface of cylindrical shell 2 is adjusted to and aims at reinforcing bar block 5, both space 6 had been rotated and aimed to the part that reinforcing bar block 5 is given prominence to, cylindrical shell can be exited from the hole of having bored and the concrete column be cut together with cutter head.
Claims (1)
