Description

Novel hard alloy drill bit

Technical Field

The utility model relates to the technical field of hard alloy drill bits, in particular to a drill bit for drilling hard materials such as rock, metal, concrete and the like.

Background

When the existing drill bit is used for drilling hard materials, the problems of serious abrasion, low drilling efficiency, poor drilling quality and the like of the drill bit are frequently encountered, and particularly when the drill bit is used for drilling high-hardness and high-toughness materials, the abrasion and consumption of the drill bit are more serious. Conventional drill bit structures generally result in wasted production materials and high manufacturing costs.

Disclosure of Invention

The utility model aims to provide a novel hard alloy drill bit so as to solve the technical scheme.

In order to achieve the above purpose, the utility model provides the following technical scheme,

The utility model provides a novel carbide drill bit, its characterized in that includes the drill bit body, the drill bit body have with handle of a knife welded welding hole, be formed with the cutting edge on the drill bit body, the cutting edge distributes the side of drill bit body to extend to drill bit body one side in welding hole one side and assemble and form the common point, be 120 distribution between the cutting edge.

The utility model further provides that a drain groove is formed between the blade parts at the side of the common point.

The utility model further provides that the drain groove is a V-shaped groove.

The utility model further provides that a blanking groove is formed between the blade parts and the drill bit body, and when the drill bit body works, the waste scraps are discharged through the draining groove and the blanking groove.

The utility model further provides that the drill bit body and the blade part are integrally formed.

The utility model has the beneficial effects that: the three-jaw alternating cutting is adopted for the blade part, the roundness of the drill is taken into account, the roundness requirement of a workpiece is guaranteed, the consumption of raw materials can be reduced during drilling, and the cutting edge is not broken and the cutter handle is not twisted off during clamping of the workpiece; and the arrangement of the welding holes has a self-guiding function.

Detailed Description

The following detailed description of embodiments of the present application will be given with reference to the accompanying drawings and examples, by which the implementation process of how the present application can be applied to solve the technical problems and achieve the technical effects can be fully understood and implemented.

As shown in fig. 1-2, the present utility model is a novel cemented carbide drill, including a drill body 10, the drill body 10 has a welding hole 20 welded with a shank, the drill body 10 is formed with blade portions 30, the blade portions 30 are distributed on the side surface of the drill body 10, and extend from one side of the welding hole 20 to one side of the drill body 10 to form a common point 40, and the blade portions 30 are distributed at 120 °. The edge portions 30 form a drain groove 50 at a position on the side of the common point 40. The drain groove 50 is a V-groove. A chute 60 is formed between the blade parts 30 and the drill body 10, and when the drill body 10 is in operation, the waste scraps are discharged through the discharge chute 50 and the chute 60. The bit body 10 is integrally formed with the blade 30.

The three-jaw alternating cutting is adopted for the blade part 30, the roundness of the drill is taken into account, the roundness requirement of a workpiece is guaranteed, the loss of raw materials can be reduced during drilling, and the cutting edge is not broken and the cutter handle is not twisted off during clamping of the workpiece; and the welding hole 20 is provided with a self-guiding function.

Certain terms are used throughout the description and claims to refer to particular components. Those of skill in the art will appreciate that a hardware manufacturer may refer to the same component by different names. The description and claims do not take the form of an element differentiated by name, but rather by functionality. As used throughout the specification and claims, the word "comprise" is an open-ended term, and thus should be interpreted to mean "include, but not limited to. By "substantially" is meant that within an acceptable error range, a person skilled in the art is able to solve the technical problem within a certain error range, substantially achieving the technical effect.

It should be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a product or system that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such product or system. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a commodity or system comprising such elements.
