Meet the requirement that smelting iron and steel blast furnace punches a hole, guarantees drilling quality, reduce production cost, extend drilling life of bit, mention
High efficiency increases economic benefit.
The task of the utility model is completed in this way: designing and producing a kind of blast furnace casting mouth of a river perforating disjunctor cross formula
Drill bit, drill bit top constitute cross drill bit in 90 degree of combined crosswises on horizontal bedding by longitudinal cutter and lateral cutter head, indulge
Respective sintering and infiltration stick type carbide bit, longitudinal cutter and lateral cutter head and bit sub above to cutter head and lateral cutter head
Portion's sintered bonds are fixed to be become at the top of cross-shaped drill bit, then sintered bonds are integrated together with drill handle part.Drill handle part
Centre bore inner cavity is provided with internal screw thread, can connect with matched drilling rod external screw thread, between centre bore and longitudinal cutter, lateral cutter head
Gap forms through-hole, for divulging information and ventilating.Longitudinal cutter and lateral cutter head are arranged in a crossed manner on the top of drill handle part, constitute ten
At the top of the drill bit of word flower-shape shape, longitudinal cutter is long rectangular plate reguline metal block, and both ends are welded on the center on drill handle part top
On the outer edge surface of hole, lateral cutter head is two sections short rectangular slab bulk metal block, is separately positioned on the two sides of longitudinal cutter, two pieces of cross
Plate face to the inner end of cutter head respectively with longitudinal cutter two sides is welded and fixed together, and the outer end of lateral cutter head is welded on bit sub
It is fixed on the centre bore outer edge surface in portion；Longitudinal cutter and lateral cutter head sintering and infiltration constitute the drill bit top of fixed cruciate flower shape
Portion, while the drill bit of disjunctor cross formula structure is fixed as at the top of drill bit with drill handle part sintered bonds.
In actual use, the utility model is connect with matched drilling rod by thread screw, and drilling machine drives drilling rod to drive and bores
Head rotation, punches a hole.Since the cutter head of the utility model is integrally formed formula structure at the top of drill bit, while at the top of drill bit
It is fixed as one with the close sintering and infiltration of drill handle part, drill bit high temperature resistant, rate of penetration is fast, and drilling straightness is high, drilling direction
Unbiased, drilling rod is not trembled, and stability is good, safe operation.Drill bit is indeformable under the high temperature conditions, and intensity is high, long service life,
Use cost is reduced, production efficiency is improved.
Implemented according to above scheme, it was demonstrated that the utility model intensity is high, and antiwear heat resisting can satisfy steelmaking furnace and go out
The needs that molten iron mouth punches a hole, long service life, operating cost is low, and remarkable in economical benefits has admirably achieved predetermined purpose.
