Description

Novel internal cooling drill bit

Technical Field

The utility model relates to a drilling technical field specifically is a novel inside cooling drill bit.

Background

The drill bit is a cutting tool used by a typical drill or drilling machine to cut a circular hole. The basic principle of the drill bit is to rotate the edge cutting of the drill bit, cut a workpiece and remove drill cuttings through a drill slot. Commonly used drill bits mainly include twist drills, flat drills, center drills, deep hole drills, and trepanning drills. Reamers and reamers are not capable of drilling solid materials, but they are also traditionally classified as drills.

The existing drill bit is not cooled in place in the thick plate processing process, so that the heat of the end part of the drill bit is too large, and the drill bit is broken in the cutting groove. This fracture will make cutter and cuttings unable take out, brings great harm for the product for the work period extension can't guarantee the engineering time limit for a project, for this reason, the utility model designs a novel inside cooling drill bit.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel inside cooling drill bit solves the cutter in the thick plate course of working, and the cooling is not in place, makes drill bit tip heat too big, leads to the drill bit to be disconnected in the condition of cutting the inslot.

In order to achieve the above object, the utility model provides a following technical scheme: including drill bit, stalk portion, flat tail and water-cooling tank, the connection of drill bit rear end is provided with the stalk portion, the connection of stalk portion rear end is provided with flat tail, the inside water-cooling tank that is provided with of drill bit and stalk portion, stalk portion top department cover has the cooling ring, the cooling ring upper end is provided with the cooling tube interface, the cooling tube interface is used for leading into drill bit and stalk portion with the coolant liquid in, makes cutting tool can obtain sufficient cooling in the course of working, improves cutter life.

Preferably, the drill bit, the handle part and the flat tail are of an integral structure, and the integral drill bit can be changed into any shape according to the process requirements.

Preferably, the drill bit and the handle are provided with water cooling grooves in the center, the top end of the handle is provided with a side hole in a penetrating and extending mode, a T-shaped rail formed by the water cooling grooves is formed in the drill bit and the handle, and the cooling liquid is introduced into the drill bit and the handle from the side face, so that the cutter can be sufficiently cooled in the machining process, and the service life of the cutter is prolonged.

Preferably, the cooling ring is matched with the sealing ring and the gasket to be fixedly sleeved at the top end position of the handle.

Preferably, the cooling pipe interface corresponds to a side hole at the top end of the handle, and the cooling pipe interface is connected with a water pipe through threads.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses the cooling effect is good, and machining efficiency is high, is convenient for change the tool bit, saves the preparation time, solves the cutter in the thick plate course of working, and the cooling is not in place, makes drill bit tip heat too big, leads to the drill bit to be disconnected in the condition of cutting cut groove.

Drawings

Fig. 1 is the overall structure schematic diagram of the internal cooling drill of the present invention.

In the figure: 1-drill bit, 2-handle, 3-flat tail, 4-water cooling groove, 5-cooling ring, 6-cooling pipe interface.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the drill bit comprises a drill bit 1, a handle part 2, a flat tail 3 and a water cooling groove 4, wherein the handle part 2 is connected and arranged at the rear end of the drill bit 1, the flat tail 3 is connected and arranged at the rear end of the handle part 2, the water cooling groove 4 is arranged inside the drill bit 1 and the handle part 2, a cooling ring 5 is sleeved at the top end of the handle part 2, a cooling pipe interface 6 is arranged at the upper end of the cooling ring 5, the drill bit 1, the handle part 2 and the flat tail 3 are of an integral structure, the integral drill bit 1 can change any shape according to process requirements and can replace a tool bit, the water cooling groove 4 is arranged at the center of the drill bit 1 and the handle part 2, a side hole is formed in the top end of the handle part 2 in a penetrating and extending mode, a T-shaped rail formed by the water cooling groove 4 is formed in the drill bit 1 and the handle part 2, cooling liquid is, the cooling ring 5 is matched with a sealing ring and a gasket to be fixedly sleeved at the top end of the handle part 2, the cooling pipe connector 6 corresponds to a side hole at the top end of the handle part 2, and the cooling pipe connector 6 is connected with a water pipe through threads.
