Abstract
The utility model discloses a drill bit for a converter maintenance machine, which is composed of a drill rod 5 and a plurality of drill teeth 6 distributed radially along an axis of the drill rod, wherein the end part of each drill tooth is provided with a bit edge groove 7, a sawtooth-shaped bit edge 8 is arranged in the bit edge groove 7, the drill tooth and the bit edge are connected through a fixing pin 4, a hollow cooling groove 1 is arranged in the drill rod to be communicated with a branch hole 2 on the drill tooth, and the cooling groove can carry out cooling for the bit edge. A combined drill bit obtained through the utility model has the advantages of easy loading and unloading, high hole-expanding rate, wear reduction of edges and improvement on the service life. The utility model can reduce the cost for the manufacture and the maintenance of drill bits and the labor intensity of operators.
Description
The utility model relates to a kind of converter maintenance and looks drill bit, can be used for converter taphole and carries out reaming, renewal.
Present normally used converter maintaining machine drill bit mostly is the monoblock type (showing as Fig. 1) the drill bit back integral replacing that lost efficacy, because of volume, weight are big, replacing is very inconvenient, particularly made when losing efficacy in the purposes, can't in time change because of drill bit is in the condition of high temperature, thereby can influence the work production of converter.Simultaneously, the drill bit cutting edge is a strip, is unsuitable for cutting hard brittle material (refractory materials), and the smear metal thing is Powdered, and stock-removing efficiency is low, the cutting edge serious wear.And in down operation of high temperature (1100～1300 ℃), drill lip lacks cooling to this drill bit usually, thus require to use red hardness preferably material be drill lip, drill bit is cost an arm and a leg.Russian patent SU269963 discloses a kind of " converter maintaining machine ", is to be equipped with at the working beam middle part to mill the accumulated slag thing that sword can be cut mill off tap hole outside surface, but can not carries out reaming.
The purpose of this utility model is to obtain a kind of novel converter maintaining machine drill bit, can in use change easily, and the stock-removing efficiency height, and can cool off drill lip.
For achieving the above object, the utility model is achieved in that
A kind of converter maintaining machine drill bit is made up of along the radially-arranged brill tooth 6 of drill rod axis drilling rod 5 and several, and there is a drilling knife groove 7 each end of boring tooth, in the drilling knife groove 7 drill lip is housed, and bores tooth and is connected by tumbler pin 4 with drill lip.
The cutting edge of drill lip 8 is a zig-zag.
The cooling tank 1 that hollow is arranged in the drilling rod 5, boring on the tooth has branched hole 2 to lead to the brill tooth ends, and drill rod end has gas lid 3.
Root three tooth tooth tops to the distance of drilling rod axis equates on the cutting edge of drill lip.
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
Fig. 1 is an integral (drill) bit structural representation in the prior art.
Fig. 2 is the utility model drill bit structure synoptic diagram
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the left view of Fig. 2.
Fig. 5 is the structural representation of drill lip in this drill bit.
Referring to Fig. 2～5, the drill bit that present embodiment provides is 4 and bores tooth, changes built-up type into by original monoblock type, original brill tooth is divided into bores tooth and drill lip two portions, and respectively there is a drilling knife groove 7 each end of boring tooth 6, and drill lip 8 is contained in the drilling knife groove 7 and connects with tumbler pin 4; In a single day find the drill lip wear out failure in the use, only need to extract out tumbler pin, change drill lip and get final product, and need not the den bohrkopf abbauen body, can simplify and change driller's preface, reduce labor intensity.The cutting edge of drill lip changes zig-zag into by original linear, and cutting object is by the Powdered bulk that becomes, and stock-removing efficiency, reaming ability obviously improve, and the cutting edge wearing and tearing also slow down to some extent.And root three teeth do not have gradient on the cutting edge of drill lip, are the reaming precision that influences tap hole in order to prevent broken teeth.In addition, cooling tank 1 is arranged in the drilling rod 5, the pressurized air of feeding can be implemented air cooling but to drill lip from branched hole 2 ejections, can slow down the hot mastication of cutting edge material like this, and improve the chip removal ability of drill bit.
Compare the combination type drill bit that the utility model obtains, dress with integral (drill) bit in the prior art Unload easy, the hole expansibility height, hole of the every expansion of integral (drill) bit needs one hour, it is split type to change sawtooth into Can shorten to below 25 minutes, and high life, converter taphole can be shortened significantly like this The replacing time, improve the utilization rate of converter, reduce manufacturing, maintenance cost and the operator of drill bit Member's labour intensity.
