Description
Technical field
The present invention relates to a kind of processing methods of the boring cutter of the embedding rock of engineering, are applied to the embedding rock drilling machine drilling of offshore wind farm
The fields such as construction, tunnel shaft drilling construction, mineral products vertical shaft drilling construction.
Background technique
Existing drilling device drilling efficiency is not high to be there are two very important factor: a. cutter is worn, Wu Fagao
Embedding rock is imitated, cutter is needed to frequently replace；B. cutter and metal object, which collide, leads to tool damage.And cause the main of this two o'clock
The reason is that caused by the button alloy block (i.e. cutter tooth) on cutter is fallen off.After button alloy block falls off from cutter hub, cause
Cutter hub is directly contacted with the cutting soil body, can not effective broken rock.After button alloy block falls off from cutter hub, button alloy block is due to close
It spends larger, is scattered in bit cutting face, cannot be discharged with mud, collide with cutter in time, cause premature tool failures.It is existing
There is the hobboing cutter cutter hub processing method in technology, as shown in attached drawing 1 to attached drawing 3, comprising the following steps: a. first processes cutter hub
At cylindrical hole one by one is presented in cutter hub periphery, which is blind hole；B. button alloy block is put into liquid nitrogen, and button is closed at this time
Gold bullion, which is endured cold, to be shunk, and button alloy block diameter is relatively small；C., button alloy block is packed into the cylindrical hole of cutter hub periphery
Interior, when cutter hub and button alloy block restore to room temperature, button alloy block diameter becomes larger, and cutter hub and button alloy block are matched in interference
Conjunction state.The shortcomings that this processing method, is that existing button alloy block (wedge-shaped hard alloy blocks) is only in the peace with cutter hub
It is wedge shape other than dress portion, mounting portion is still cylinder, and the connection of button alloy block and cutter hub uses top plug-in type, i.e., by ball
For ratcheting gold bullion to being inserted into inside cutter hub outside cutter hub, it is real that the fixation between button alloy block and cutter hub only relies on interference fit
Existing, or the adhesive added in connection realizes, which haves the defects that structural, and insert cutter is in work shape
The load being subject under state is extremely complex, and button alloy block is caused to be very easy to fall off in the case where stress.
Summary of the invention
To solve the above problems, the purpose of the present invention is to provide a kind of processing methods of the boring cutter of the embedding rock of engineering.
