Abstract
The utility model relates to a built-up hard alloy grinder which comprises a hard alloy block (1), a pushing block (2), a grinding disc (3), a tire body (4) and a drill buckle (5). The utility model has advantages that the utility model avoids the defects that residual stress generated by the hard alloy block and the steel tire body lead the phenomena of flaking, tipping, cracking, etc. on the hard alloy block. Expensive brazing filler metal is saved. The difficultly controlled brazing technique of the hard alloy block and steel material is converted into a built-up type process technique. The cutting ability of the hard alloy block is raised, and the service life of the hard alloy of the grinder is extended. The tire body can be repeatedly used, thus a great amount of high quality steel material is saved, and transport capability is saved.
Description
The utility model belongs to oil, gas field, mine, geological drilling engineering tools technical field.
In the drilling process of petroleum and natural gas, mine, Geological Engineering, the iron and steel junk is often arranged, or drilling tool fracture falls in the well, cause serious engineering accident.In the time can't salvaging junk, be releasing accident as early as possible, often use the iron and steel junk or the drilling tool top of fish of abrasive dust device grinding down-hole.The general abrasive dust device that uses all is with in the hole of carbide alloy block brazing on carcass, and coefficient differs greatly because line Peng of carbide alloy and steel is expanded, and (the bloated coefficient of carbide alloy line Peng is 6 * 10
-6℃
-1, steel is 12 * 10
-6℃
-1).Residual stress is big after the soldering, causes hard alloy blocks to crack, and is easy to take place flake and tipping in the use.
The purpose of this utility model is to provide a kind of assembling carbide alloy abrasive dust device, crackle, flake, tipping that the residual stress concentrations that it has avoided carbide alloy to produce because of soldering causes, the service life of having improved the abrasive dust device.
The utility model comprises hard alloy blocks (1), a piece (2), mill (3), carcass (4), drilling tool button (5), and figure (1) is a structure chart.Hard alloy blocks (1) mill (3) endoporus of packing into is welded on the mill (3) with jacking block (2) village, is assembled into a sub-assembly; Mill (3) welds with carcass (4); Drilling tool button (5) is connected with the drilling tool lower end with thread forms.
The utility model has the advantages that: the soldering processes technology of hard alloy blocks that will be difficult to grasp and steel is converted into the packaging technology technology of hard alloy blocks and steel; Eliminate the hard alloy blocks that causes because of the soldering residual stress and attacked line, flake and tipping; Prolonged abrasive dust device service life; After the hard alloy blocks wearing and tearing, only need to change the mill assembly, and carcass is reusable, thereby saves a large amount of high-quality carcass steel and carcass processing charges; Reduce production costs, saved transport power
Accompanying drawing is the structure chart of assembling carbide alloy abrasive dust device
Claims (1)
- Assembling carbide alloy abrasive dust device is characterized in that comprising hard alloy blocks (1), jacking block (2), mill (3), carcass (4), drilling tool button (5).Hard alloy blocks (1) is assembled in mill (3) hole, is compressed by jacking block (2), is assembled into an assembly, and mill (3) is connected with carcass (4), the upper end car system drilling tool button (5) of carcass.
