Abstract
The utility model relates to a beset aiguille in a pudding blast furnace iron output mouth, which is composed of an aiguille body 1 and more than two hard alloy blades 2; wherein the hard alloy blades are embedded on the top of the aiguille body. An ash output groove 6 is positioned on the aiguille body which is positioned between every two neighboring blades; the center of the aiguille body has an air inlet 3 which passes through the aiguille body; the joint 5 of the rail of the aiguille body is provided with a connecting worm. The blades are hard alloy blades and are embedded into the top of the aiguille body. The aiguille body smoothly outputs scraps, has good intensity blades, and is tough with nick, good in interchange ability, and long in service life.
Description
Technical field
The utility model relates to the bit tool that iron-smelting blast furnace iron notch opening is used.
Background technology
The current iron-smelting blast furnace drill bit that mouth of a river opening is used that taps a blast furnace, a kind of is to be provided with the mach interalloy tool steel of forging of cooling air inlet hole drill bit from external introduction.This kind drill bit does not move back ash bits duct, takes impact type to advance to bore during use, and the ash bits withdraw from from the slit of bit face, the shortcoming of this drill bit is that the ash bits withdraw from not smooth, drill bit material red hardness is poor, when drill bit pierces the body of heater certain depth, owing to the hardness of the blast furnace temperatures involved drill bit blade effectiveness of losing the job, drill bit is connected by adapter sleeve with drilling rod and connects, the drill bit part is many, uses combination complicated, and machining is many, the cost height, every cover price reaches about 250 yuan; In addition, the connection portion of this kind drill bit is a special screw thread, and interchangeability is poor, changes very inconvenient.Another kind of drill bit is the iron-smelting blast furnace iron notch start bit that Chinese patent 93224046.1 provides.This drill bit is a two-phase built-up type drill bit, form by drill main body and cutting tip, the drill main body head is being inlayed 2 above Wimet steel blades, afterbody has general connecting thread, there is the intake opening that runs through entire body at the center, has the axial pass trough of ash discharge bits on main body between per 2 adjacent knife blades.This drill bit ash discharge bits are unobstructed, can advance to bore continuously, and resistance to elevated temperatures is good, renders a service height, and connecting thread interchangeability is better.But the carbide-tipped lathe tool blade of this drill bit, the big normal breach that produces of fragility, it is to weld easily to come off that drill bit is connected with drilling rod.99238308.8 the precision casting integral finish drill bit that provides is simple in structure, easy to manufacture, and is because of the frame of the bit and the blade of this drill bit is the integral body that alloy casting becomes, more with alloy steel products.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned drill bit, provides a kind of ash discharge bits smooth, and cutter intensity is good, the iron-smelting blast furnace iron notch start bit of being convenient to exchange.The iron-smelting blast furnace iron notch start bit of realizing the utility model purpose is a kind of inserted two-phase tapping outlet drill bit, the two-phase combined drill that this drill bit is made up of drill main body and the blade that is fixed on its head, drill bit head is uniform is inlaying 2 with cutter, chip discharging groove is vertically arranged on the drill main body between 2 whenever adjacent blades, bit central has the intake opening that runs through entire body, there is connecting thread afterbody connection section office, characteristics are that the blade embed type is embedded in the drill main body head, and blade is ore deposit, a Wimet ground blade.
It is all kinds of that this drill bit is divided into two sword formulas, three sword formulas, four sword formulas etc. according to embedded knife number.
The utility model drill bit, because move back grey junk slot, the ash discharge bits are unobstructed, can advance brill continuously and impact brill, the blade that is inlaid into is ore deposit, a ground blade, and resistance to elevated temperatures is good, the deliquescing of can at high temperature not annealing, render a service height, drill main body afterbody connecting thread is general internal thread or outside screw, is convenient to change drilling rod.
Description of drawings
Fig. 1,2 has the master of the iron-smelting blast furnace iron notch opening insert bit of four blades to look synoptic diagram, schematic top plan view.
Fig. 3 is the schematic top plan view that the iron-smelting blast furnace iron notch opening insert bit of three blades is arranged.
Among the figure: the 1st, drill main body, the 2nd, blade, the 3rd, intake opening, the 4th, drill main body head, the 5th, connecting thread, the 6th, ash discharge bits groove.
Embodiment
This iron-smelting blast furnace iron notch opening insert bit, comprise a high temperature steel drill main body 1, the connection screw thread is arranged in the afterbody junction 5 of drill main body 1, uniformly on drill main body head 4 inlaying 4 or ore deposit, 3 Wimet ground blade 2, have the intake opening 3 that runs through entire body in the centre of drill main body 1, this hole is done into, and cooling air cools off drill bit and blows ash and use, at the groove 6 that has 1 ash discharge bits on the body head 4 between per 2 adjacent blades, when drill bit advances to bore, blade is cut the ash bits that get off and is moved to the drill bit afterbody from the head along groove 6, discharges from afterbody.
This drill bit is embedded in the drill main body head with YK-45, YG-15, ore deposit, YG8-C ground blade embed type, with behind the welding rod full weld, grinds off welding slag and makes.This drill bit result of use is good, tough and tensile not breach, and the life-span is long, and interchangeability is good.
Claims (1)
1, a kind of iron-smelting blast furnace iron notch start bit, it is by drill main body (1) and be fixed on the two-phase combined drill that the blade (2) on its head (4) is formed, there is the intake opening (3) that runs through entire body at drill main body (1) center, connecting thread has been located in afterbody connection portion (5), the head (4) of drill main body (1) is upward uniform is inlaying 2 with cutter (2), chip discharging groove (6) is vertically arranged on the drill main body between 2 whenever adjacent blades, it is characterized in that blade (2) embed type is embedded in the drill main body head (4), blade is ore deposit, a Wimet ground blade.
