Abstract
The invention aims to disclose a drill head. The service life of the drill head can be prolonged under the condition that good cutting performance is guaranteed. The drill head provided by the invention comprises a handle part and a blade part. The key of the drill head is as follows: the handle part is made of high-speed steel, the blade part is made of hard alloy, and the handle part is in fixed connection with the blade part. The blade part made of hard alloy is capable of guaranteeing the good cutting performance, and the handle part made of high-speed steel is capable of enabling the whole drill head to have a certain flexibility to ensure that the vibration generated in the process of processing is reduced or eliminated, so that the process precision under a severe condition is enhanced, and the precision of a workpiece and the service life of a cutter are guaranteed. Through changing materials of the handle part and the blade part of the drill head, the service life of the drill head is prolonged under the condition that the good cutting performance is guaranteed, therefore, the use cost of the cutter is reduced.
Description
Technical field
The invention belongs to cutter manufacturing technology field, specially refer to a kind of drill bit.
Background technology
Drill bit with an important component part in the cutter, is mainly used the roughing with the hole as machining.Along with the development of mechanical industry, the consumption of drill bit grows with each passing day, especially the major diameter drill bit.But the price of bar rises steadily, and has brought huge cost pressure to processing industry.Existing drill bit generally all is a whole hard alloy, though carbide alloy has higher hardness, can satisfy the requirement of processing relatively hard materials, and its toughness is relatively poor, if bigger vibrations are arranged, cutter and part is scrapped in process.
Summary of the invention
The objective of the invention is to propose a kind of drill bit, can under the prerequisite that guarantees its good cutting ability, prolong its service life.
Drill bit of the present invention comprises shank and blade, and key is that described shank adopts high-speed steel to make, and described blade adopts carbide alloy to make, and described shank is fixedlyed connected with blade.
The blade of carbide alloy can guarantee that it has good cutting ability, the shank of high-speed steel makes drill bit integral body have certain toughness, can reduce or eliminate the vibrations that in process, produce, thereby improve its machining accuracy under mal-condition, guarantee workpiece accuracy and cutter life.
Further, the end of described shank is provided with anti-rotation groove radially, and described blade is provided with the radially boss that cooperates with described anti-rotation groove, and described boss is connected in the anti-rotation groove.Anti-rotation groove and boss cooperate, and shank and blade are rotated synchronously, reduce rotary action power between the two, and then can prevent that both from separating.
Further, described shank and blade welding are fixing, and be fixing reliable.
Drill bit of the present invention, prolongs its service life, thereby has reduced the use cost of cutter under the prerequisite that guarantees its good cutting ability by changing the material of shank and blade.
Description of drawings
Fig. 1 is the structural representation of drill bit of the present invention.
Among the figure: 1, shank; 2, blade.
The specific embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail embodiment.
Embodiment 1:
As shown in Figure 1, the drill bit of present embodiment comprises shank 1 and blade 2, and shank 1 adopts high-speed steel to make, and blade 2 adopts carbide alloy to make, and shank 1 and blade 2 welding are fixing.
The end of shank 1 is provided with anti-rotation groove radially, and blade is provided with the radially boss that cooperates with anti-rotation groove, and boss is connected in the anti-rotation groove.Anti-rotation groove and boss cooperate, and shank 1 and blade are rotated synchronously, reduce rotary action power between the two, and then can prevent that both from separating (anti-rotation groove and boss do not draw among the figure).
The blade of carbide alloy can guarantee that it has good cutting ability, the shank of high-speed steel makes drill bit integral body have certain toughness, can reduce or eliminate the vibrations that in process, produce, thereby improve its machining accuracy under mal-condition, guarantee workpiece accuracy and cutter life.
Claims (3)
1. a drill bit comprises shank and blade, it is characterized in that described shank adopts high-speed steel to make, and described blade adopts carbide alloy to make, and described shank is fixedlyed connected with blade.
2. drill bit according to claim 1, the end that it is characterized in that described shank is provided with anti-rotation groove radially, and described blade is provided with the radially boss that cooperates with described anti-rotation groove, and described boss is connected in the anti-rotation groove.
