Abstract
The utility model relates to a drill bit used for hole drilling without rock core such as drilling, engineering, coal mines, etc., being composed of a steel sleeve and ball teeth. The utility model is characterized in that the steel sleeve is sheathed on the ball teeth in a fastening way, causing the steel sleeve to be directly welded on a rolling cutter body. The utility model has the advantages of simple manufacturing technique, low cost, high utilization rate of the ball teeth and uneasy disconnection.
Description
The utility model has related to a kind of drill bit, specifically a kind of three gear wheels that oil drilling is used, insert cutter and drag bit that no cores such as engineering and colliery are boring of being used for.
What the boring insert cutter of the no cores such as center three gear wheels, engineering and colliery that at present domestic and international oil drilling is used adopted all is hard alloy spherical-teeths, its using method is with drilling blind hole on the hobboing cutter body, and whole hobboing cutter body is heated to uniform temperature, with the ball tooth with the centerless grinder grinding and freezing after, with forcing press the ball tooth pressure is advanced in the blind hole on the hobboing cutter body.There is following problem in this method: 1. have part ball tooth to be embedded in the hobboing cutter body, can not cut the rock stratum and slattern; 2. can not guarantee that each ball tooth can both be fastening, ball tooth obscission easily takes place; 3. complex process, cost height.
The purpose of this utility model just provides a kind of composite hard alloy ball tooth to overcome above-mentioned deficiency.
For achieving the above object, the utility model is made up of ball tooth and steel bushing 2, it is characterized in that: steel bushing 2 securely is enclosed within on the ball tooth 1.Its method is that steel bushing 2 is heated, and ball tooth 1 is pressed in the cover, and steel bushing 2 is with ball tooth 1 fastening becoming one.
Because the utility model has adopted the structure of steel bushing and the fastening one of ball tooth, and it can directly be welded on the hobboing cutter body, so the utility model manufacturing process is simple, cost of manufacture is low, ball tooth utilization rate height, difficult drop-off.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of the utility model embodiment.
Fig. 4 is the upward view of Fig. 3.
Further describe the utility model below in conjunction with drawings and Examples.
The utility model embodiment is warmed to steel bushing 2 more than 800 ℃, and ball tooth 1 is pressed in the cover, treat its cooling after, steel bushing 2 is with ball tooth 1 fastening forming.Only the utility model need be welded on the hobboing cutter body with welding rod in use and get final product.
