Abstract
The invention provides a hob cutter ring provided with alloy strips in an embedded mode. The hob cutter ring mainly comprises a cutter ring base body and the alloy strips. The section of each alloy strip is of a T-type structure, the alloy strips are embedded in the cutter ring base body in a brazing mode, and the alloy strips are seamlessly distributed on the cutter ring base body in a whole ring mode or are closely distributed at intervals. Impact bending moments borne by the alloy strips in the rock breaking process are reduced due to the T-type structure, and the alloy strips are prevented from breaking; meanwhile, the periphery areas of the ally strips of the hob cutter ring are protected, the anti-wearing capacity of the cutter ring base body is improved, the alloy strips are prevented from loosening and disengaging, the service life of a hob is prolonged and rock breaking efficiency is improved.
Description
Technical field
The present invention relates to shield engine disk type hobbing cutter ring in shield machine industry, is a kind of brand-new embedded alloy bar hobboing cutter cutter ring.
Background technology
Disk hobbing cutter used for shielded tunnel boring machine cutter ring belongs to the accessory easy to wear of shield machine disk cutter, and disk cutter is arranged on the rotating cutter-head of shield machine, and the wedge shape cutter ring wedging rock mass of disk cutter makes its fragmentation.In rock break-off process, cutter ring of disc cutter not only bears very large radially broken rock power, stands again the sharp wear of hard mineral matter in rock simultaneously.Serious wearing and tearing have reduced the broken rock speed of development machine, must regularly change hobboing cutter cutter ring, and complete machine operating efficiency is reduced, and excavation cost improves.Therefore work out
oneplant more wear-resisting hobboing cutter cutter ring extremely urgent.
Summary of the invention
The object of the present invention is to provide a kind of disk hobbing cutter used for shielded tunnel boring machine cutter ring more wear-resisting, rational in infrastructure, to solve in underground construction process, hobboing cutter cutter ring is too fast, wearing and tearing, and then the defect that causes hobboing cutter to scrap too early,
The present invention is achieved in that
An embedded alloy bar hobboing cutter cutter ring, is mainly comprised of cutter ring matrix (1), alloy bar (2).It is characterized by, alloy bar (2) truncation surface becomes T-shape structure, and it is upper that alloy bar is embedded in cutter ring matrix (1) by brazing mode, alloy bar whole circle on cutter ring matrix is seamless arrange or interval densely arranged.The operating principle of this hobboing cutter cutter ring is, hobboing cutter cutter ring hot charging is on hobboing cutter cutter hub, during cutterhead work, hobboing cutter cutter ring first contacts with excavation face, under thrust, be pressed on scar, rotation along with cutterhead, hobboing cutter revolves round the sun around cutterhead central axis on the one hand, around self axis rotation, under the thrust and torque acting in conjunction of cutterhead, hobboing cutter cutter ring is pressed into rock simultaneously, to rock, will produce the comprehensive functions such as extruding, shearing, drawing crack, rock is cracked, and along with the continuation rotation of cutterhead, carg will depart from parent.
The present invention compares with existing hobboing cutter cutter ring, cutter ring blade is inlayed high-anti-friction hard alloy bar, alloy bar truncation surface becomes T-shape structure, alloy bar is embedded on cutter ring matrix by brazing mode, alloy bar whole circle on cutter ring matrix is seamless arrange or interval densely arranged, this T-shape structure decrease the impact moment of flexure that in rock break-off process, alloy bar bears, prevented the fracture of alloy bar; Hobboing cutter cutter ring alloy bar perimeter zone is played a protective role simultaneously, strengthened the antiwear property of hobboing cutter cutter ring body, thereby prevent the loosening of alloy bar and come off, extend the application life of hobboing cutter, improve efficiency of breaking rock.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention; Fig. 2 is the left sectional view of structure of the present invention; Fig. 3 is that alloy bar top is the structure sectional view of plane; Fig. 4 is that alloy bar top is convex structure sectional view; Fig. 5 is the structure sectional view of one-tenth obtuse angle, alloy top form.
In accompanying drawing, (1) is cutter ring matrix, and (2) are alloy bar.
The specific embodiment
With reference to accompanying drawing, a kind of embedded alloy bar hobboing cutter cutter ring, is mainly comprised of cutter ring matrix (1), alloy bar (2).Main feature is that alloy bar truncation surface becomes T-shape structure, alloy bar is embedded on cutter ring matrix by brazing mode, alloy bar whole circle on cutter ring matrix is seamless arrange or interval densely arranged, this T-shape structure decrease the impact moment of flexure that in rock break-off process, alloy bar bears, prevented the fracture of alloy bar; Hobboing cutter cutter ring alloy bar perimeter zone is played a protective role simultaneously, strengthened the antiwear property of hobboing cutter cutter ring body, thereby prevent the loosening of alloy bar and come off, extend the application life of hobboing cutter, improve efficiency of breaking rock.
Below in conjunction with accompanying drawing, the invention will be further described:
Figure 1 shows that the present invention adopts alloy bar (2) at the upper seamless arrangement form of whole circle of cutter ring matrix (1); Figure 2 shows that the present invention adopts alloy bar (2) in the densely arranged form in the upper interval of cutter ring matrix (1); Figure 3 shows that the invention of this reality adopts the alloy bar top plane alloy bar equal with cutter ring matrix exposed face; Figure 4 shows that the present invention adopts top to become circular-arc, exposes the alloy bar of cutter ring matrix; Shown in figure, 5 for the present invention adopts one-tenth obtuse angle, alloy top form, and expose cutter ring matrix.
The invention of this reality selects these several alloy bar forms all can protect cutter ring matrix; can greatly strengthen the anti-wear performance of cutter ring; and can select different-alloy strips effectively to protect cutter ring matrix according to different geology, extend the application life of hobboing cutter cutter ring, improve efficiency of breaking rock.
Claims (5)
