Abstract
The invention discloses a liquid cooling drill bit which comprises a rod body, a drill bit body, a main cutting blade, a chip groove and a liquid cooling hole. The front end of the rod body is provided with the drill bit body provided with the cutting blade. The chip groove is formed in the rod body. The liquid cooling hole is coaxially formed in the center of the rod body in the axis direction of the rod body. Due to the way, the liquid cooling drill bit has the advantages of being high in reliability, compact in structure, high in strength and rigidity, good in chip removal, low in work temperature, effective in heat dissipation and wide in application range, and has wide market prospects in the mechanical field.
Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of liquid cooling drill bit.
Background technology
Drill bit is to go out through hole or blind hole in order to drilling on solid material, and can be to the cutter of existing hole reaming, conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill, in drilling process, inevitably produce amount of heat, due to the particularity of Drilling operation, heat is easily piled up, borehole accuracy is declined, bit wear seriously and easily causes built-up edge, infringement cutter, and simultaneously traditional cooling means is also difficult for boring effective cooling.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of liquid cooling drill bit, and by design liquid cooling hole and apopore, drill bit can form effective cooling at front end; By using carbide alloy steel making drill bit, meet preferably the demand of drill bit rigidity and hardness; Be designed with 2 chip areas, effectively discharge smear metal; Tip designs has fast connector, realizes drill bit quick-replaceable and more effective power transmission.The advantage such as have that reliability is high, compact conformation, intensity be large, and hardness is higher, and chip removal is good, and operating temperature is low, efficiently radiates heat, and the scope of application is wide, has market prospects widely at mechanical field simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of liquid cooling drill bit is provided, comprise: the body of rod, drill bit, main cutting edge, chip area, liquid cooling hole, lever front end is provided with drill bit, drill bit is provided with cutting edge, on the body of rod, be furnished with chip area,, there is a liquid cooling hole at body of rod center along body of rod axis direction is coaxially arranged.
In a preferred embodiment of the present invention, described drill bit angle is 108 °.
In a preferred embodiment of the present invention, described chip area has two, becomes double helix shape to be arranged in body of rod both sides, and chip area is provided with front cutting edge.
In a preferred embodiment of the present invention, described body of rod lower end is provided with apopore, and described apopore is arranged in chip area, and apopore axis is vertical and crossing with body of rod axis, and apopore is communicated with liquid cooling hole.
In a preferred embodiment of the present invention, described body of rod rear end is provided with snap joint, and described snap joint is semi-cylindrical hill, is symmetrically distributed in body of rod both sides.
In a preferred embodiment of the present invention, described liquid cooling drill bit adopts carbide alloy steel making.
The invention has the beneficial effects as follows: liquid cooling drill bit of the present invention is by design liquid cooling hole and apopore, and drill bit can form effective cooling at front end; By using carbide alloy steel making drill bit, meet preferably the demand of drill bit rigidity and hardness; Be designed with 2 chip areas, effectively discharge smear metal; Tip designs has fast connector, realizes drill bit quick-replaceable and more effective power transmission.The advantage such as have that reliability is high, compact conformation, intensity be large, and hardness is higher, and chip removal is good, and operating temperature is low, efficiently radiates heat, and the scope of application is wide, has market prospects widely at mechanical field simultaneously.
