Description
Technical field
The present invention relates to cutter ring of disc cutter technical field, the cutter ring of disc cutter development of specially a kind of high abrasion.
Background technique
Disk cutter is a kind of cutter of replaceable cutter ring, is usually divided into single-blade, twolip and multiple-cutting-edge, often with radial
Or spiral distribution, on cutter head of shield machine, shield machine tunnels forward under the pressure of jack, while cutter head of shield machine is made
Rotary motion, the cutter being mounted on cutter head of shield machine simultaneously, oneself are made certainly with cutterhead revolution under frictional force and pressure
Turn, rolls shear action to generate using cutter ring cutting edge to rock surface, disk cutter broken rock working principle is understood that
Are as follows: cutter ring of disc cutter first squeezes out a slot in rock when driving, and splitting for initial pulling damage is generated around slot
Line, well are constantly used to cutter into the lozenges of cutter ring plays failure by shear, initial tensioning to the rock on cutter ring both sides
Destroy crackle can the rock crackle forming under shearing force between rock tangential direction Continuous rapid expansion, adjacent cutter can produce
Life influences each other, and generates further pulling damage, generates the phacolith between adjacent grooving under this pulling damage larger
Crumbling get off, disk cutter work when other than the normal pressure of cutter ring circumferential direction to be born, also by cutter ring tangentially
The effect of alternate stress in frictional force and lateral, stress is complicated, and working environment is severe, the rock of stratum and peeling
There are grinding, erosion effect to cutter ring, cutter hub, easily cause the initial failure of cutter, to the rock breaking efficiency and cutter pair of cutter
The tolerance performance of working environment and the stability of tool quality propose high requirement, and the quality of cutter directly determines
Quality, cost, safety and the efficiency of engineering are one of the core technologies in tunnel and Shield Method Tunnel for Metro construction.
The working environment of cutter ring of disc cutter is severe, and force environment is complicated, and existing cutter ring of disc cutter is by steel
Limitation, hardness and wearability be not high, is easy to be worn by hard stone after a period of operation, causes cutter ring due to abrasion
Damage, limits the service life of cutter ring of disc cutter, reduces the practicability of cutter ring of disc cutter.
