Abstract
The utility model discloses a coal cutter cutting tooth and belongs to rock breaking tools. The coal cutter cutting tooth comprises a cutting tooth head, a cutting tooth handle, and hard alloy, wherein the cutting tooth head and the cutting tooth handle form an integral structure, and the hard alloy is brazed on the cutting tooth head. The coal cutter cutting tooth can prevent the phenomenon that the hard alloy falls off since the tooth head is worn to flat or the tooth head is worn quicker than the hard alloy. The coal cutter cutting tooth can lay a solid foundation for continuous working of a mining machine and lowering halt and maintenance cost.
Description
Technical field
The utility model belongs to rock crushing tool, relates in particular to a kind of coal winning machine cutting bit.
Background technology
In the prior art; because the working condition of conical pick is more abominable, just easily tooth head Fast Wearing appears in use, and carbide alloy comes off in the situation that lack topping; increase shutdown, the frequency of maintenance of coal mining enterprise's coal-winning machine, virtually increased mining costs.The situation that coal winning machine cutting bit manufacturing enterprise comes off in order to reduce carbide alloy can only take to increase production technology, and the head built-up welding strengthens the carbide alloy topping, has virtually increased cost of production.
Summary of the invention
The utility model aims to provide long a kind of coal winning machine cutting bit in a kind of application life.
The utility model is made of cutting pick head, cutting pick handle, carbide alloy, and cutting pick head and cutting pick handle are structure as a whole, and soldering has carbide alloy on the cutting pick head.
Described carbide alloy is the KE9 material;
Described cutting pick head is made of frustum and cylinder, and frustum and cylinder are overall structure, and the end of cutting pick head is provided with groove;
The diameter of the large conical surface of described frustum is 55mm, and the diameter of the little conical surface is 26.5mm, and the length of frustum is 72mm, and cylindrical length is 13mm, and cylindrical diameter is 55mm;
Described carbide alloy is made of shank and head, and shank is embedded in the groove of cutting pick head and with the cutting pick head soldering and is integrated, and head is cone.
The utility model is achieved in that when conical pick head of the present utility model pierces coal, locked middlings or Polodyakonov coefficient coefficient f and is not more than 5 soft rock; can protect the denticle head; reduce the wearing and tearing of denticle head, reduce to greatest extent the early fallout that causes carbide alloy because of the Fast Wearing of denticle head.The denticle head position has improved antiwear property, and carbide alloy weares and teares synchronously, until carbide alloy all wearing and tearing are complete.
The utility model has avoided tooth head mill flat or cause the generation of carbide alloy obscission faster than the wearing and tearing of carbide alloy.Be the continuous operation of coal-winning machine, reduce shutdown and maintenance cost and lay a solid foundation.
