Definitions

  • the utility model relates to a hole-drilling drill bit of a stone sheet and an artificial stone sheet. Background technique
  • the cooling water holes on the existing stone sheet and artificial stone sheet top-drilling drill bits are usually eccentric holes, such as the top-drill drill bit of Chinese Patent No. 99319002.2. Because the shaft of this type of drill is relatively thin, the cooling water hole must be It has a certain hole diameter, so this type of drill bit can easily come out from the side of the drill shaft when processing the cooling water hole, and the drill bit is discarded. Summary of the invention
  • the technical problem to be solved by the present utility model is to provide a thin-plate hole-boring drill bit which overcomes the above-mentioned defects.
  • the utility model adopts the following technical scheme: It includes a drill pipe, a cutting head, and a cooling water hole is provided in the drill pipe and the cutting head; the cooling water hole is composed of a water guide hole and a water spray hole, and the water guide is The hole is located in the drill pipe section, concentric with the drill pipe, the water jet hole is located in the cutting head, its upper end is connected with the water guide hole, and its lower end outlet is eccentrically arranged on the lower end face of the cutting head, and is connected with the drainage groove.
  • the cooling water hole is divided into a water guiding hole which is concentric with the drill pipe and a water spray hole located on the cutting head part, which not only eliminates the existing water drill hole which is easy to be out of the drill pipe during processing Problems, and it is convenient to increase the diameter of the water guide holes, so that the cooling water holes are not easily blocked.
  • the utility model can also adopt the following further technical solutions at the same time:
  • the cutting head is frustum-shaped, and its outer surface is provided with hard cutting particles such as diamond. It is also provided with a second cutting function above the cutting head. The distance between the second cutting function and the cutting head corresponds to the depth of the drilled hole. The cutting radius of the cutting function is greater than the radius of the drilled hole. Because the cutting function is also provided above the cutting head, the thickness of the surrounding area of the hole can be controlled while drilling. Especially for thin plates, the flatness of the curtain wall can be ensured even if there is an error in the plate thickness. And can help improve the seismic performance of the curtain wall.
  • the second cutting function may be hard cutting particles such as diamond stuck to the lower end face of the drill tail.
  • the second cutting function can also be provided on the drill pipe.
  • the second cutting function member may include a base body connected to the drill pipe, and hard cutting particles such as diamond adhered to the lower end surface of the base body.
  • the cutting head is threadedly connected to the drill rod. In this way, when the cutting head is worn, it can be easily replaced without having to abandon the drill rod, which can reduce the use cost.
  • the diameter of the water guide holes is slightly larger than that of the water spray holes, and the drainage grooves are mesh-shaped or distributed radially around the water spray holes.
  • a water guiding cone surface is processed in the drill tail thread assembly hole.
  • the drill tail thread assembly hole includes a smooth positioning hole segment and a thread segment, and the positioning hole segment is concentric with the thread segment. In this way, the concentricity of the drill bit and the power output head of the drill rig is ensured, and the defect that the past relying only on the thread for mounting is likely to cause the eccentricity of the drill bit and the drill output head.

Abstract

La présente invention se rapporte à un trépan utilisé pour une pièce à travailler à paroi mince. Ce trépan comprend une tige de trépan et un élément tranchant, tous deux dotés d'un orifice de refroidissement à eau. Cet orifice de refroidissement à eau comporte deux parties que sont un orifice d'amenée de l'eau et un orifice de pulvérisation de l'eau. L'orifice d'amenée de l'eau est formé coaxialement dans la tige trépan tandis que l'orifice de pulvérisation de l'eau est disposé dans l'élément tranchant de sorte que sa partie supérieure soit raccordée à l'orifice d'amenée de l'eau. La sortie inférieure de l'orifice de pulvérisation de l'eau, qui est disposée de manière excentrique sur la surface inférieure de l'élément tranchant, est raccordée à une rainure de drainage. Le trépan conforme à la présente invention, dans lequel l'orifice de refroidissement à eau est divisé en deux parties que sont un orifice d'amenée de l'eau qui est concentrique par rapport à la tige du trépan et un orifice de pulvérisation de l'eau formé dans l'élément tranchant, ne permet pas seulement de résoudre le problème posé dans les trépans classiques par la facilité de déviation de la tige du trépan par rapport à l'orifice de refroidissement à eau en cours d'usinage, mais permet également d'agrandir le diamètre de l'orifice d'amenée de l'eau de sorte que celui-ci ne se bouche pas facilement.
