Abstract
The invention belongs to the field of drill bits and particularly relates to a welded alloy drill comprising a drill bit shank. A drill bit connecting portion is arranged at one end of the drill bit shank, a drill bit positioning portion is arranged at the other end of the drill bit shank, an alloy drill body is welded to the drill bit connecting portion, a drill point is arranged at the end of the alloy drill body, and drilling retaining plates are arranged on the peripheral surface of the joint of the alloy drill body and the drill bit connecting portion. The welded alloy drill has the advantages that drillings can be retained through the drillings retaining plates, and cost can be saved as the drill bit is welded.
Description
Technical field
The invention belongs to drill bit field, specifically a kind of welding alloy bores.
Background technology
Drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Used normal drill bit generally uses material for carbide alloy and high-speed steel, the drill bit made with Hardmetal materials, although durable in use, price is very high, and the outside diameter produced can not exceed
production and application cost is high, the drill bit made with high-speed steel, although low price, use cost relative moderate, the low easy fracture of the drill bit rigidity due to high speed steel material, so use cumbersome, often change.
Summary of the invention
The present invention is directed to the weak point existed in above-mentioned technology, propose a kind of welding alloy and bore, save use cost by the mode of welding.
The invention provides following technical scheme:
Welding alloy bores, and it comprises drill handle part, and drill handle part one end is provided with drill bit connecting portion, the other end is provided with drill bit location division, drill bit connecting portion is welded with alloy drill body, and alloy drill body end is provided with apex point, and the side face of alloy drill body and drill bit connecting portion junction is provided with drilling cuttings baffle plate.
Described apex point is provided with alloy blade.
Described drill bit location division is made up of tapered portion and cylindrical portion.
Advantage of the present invention can block chip by drilling cuttings baffle plate, and the drill bit simultaneously welded can save cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, welding alloy bores, it comprises drill handle part 1, drill handle part 1 one end is provided with drill bit connecting portion 2, the other end is provided with drill bit location division 3, drill bit connecting portion 2 is welded with alloy drill body 4, and alloy drill body end is provided with apex point 5, and alloy drill body 4 is connected 2 places side face with drill bit connecting portion is provided with drilling cuttings and keeps off 6 plates.
Described apex point is provided with alloy blade 7.
Described drill bit location division forms b by tapered portion a and cylindrical portion.
