Abstract
The utility model discloses a shield machine hob ring, and belongs to the field of cutters for shield machines. The shield machine hob ring mainly comprises a ring body, and a hard alloy rolling ring is brazed on the periphery of the ring body. The shield machine hob ring is characterized in that: the rolling ring consists of a plurality of arc strips and is brazed in an annular inner groove of the ring body; and two transverse lateral surfaces of each arc strip are provided with a raised longitudinal rib respectively. The shield machine hob ring is convenient for brazing and firm to braze and has strong abrasion resistance; and the working performance of the hob ring is effectively improved, and the integral service life of a hob for a shield machine is prolonged.
Description
Technical field
The utility model belongs to shield machine and uses the cutter field, is a kind of improved shield machine hobboing cutter circle specifically.
Background technology
Shield machine belongs to the rapid wear accessory of shield machine with the hobboing cutter circle, is installed on the hob head of shield machine rotating cutter-head.Mainly, finish constructions such as tunnel excavation, driving jointly with multiple shield machine cutter work compound.Hobboing cutter circle performance is the key of hobboing cutter bulk life time.Now used hobboing cutter circle is common carbide alloy bar, and the soldering difficulty is big, and fastness is poor, causes not wear-resistantly, and working life is short.
Summary of the invention
The purpose of this utility model is to provide a kind of shield machine roller cutter circle of being convenient to soldering, and fastness is strong, long working life.
The utility model is achieved in that
The shield machine roller cutter circle mainly comprises circle body, and soldering has carbide alloy rolling ring on the circle body periphery, it is characterized in that: described carbide alloy rolling ring is made up of a plurality of arc strips, and soldering is in the annular inner groovy of circle body; Be respectively arranged with the longitudinal rib of projection on two horizontal sides of each arc strip.
After the utility model adopted said structure, the carbide alloy rolling ring soldering of being made up of a plurality of arc strips was in the annular inner groovy of circle body, and each arc strip is provided with protruding longitudinal rib, is convenient to soldering, and brazing filler metal is firm, and abrasion resistance is strong; Effectively improve the service behaviour of hobboing cutter circle, improve the whole service life of shield machine with hobboing cutter.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the vertical view of Fig. 1; Fig. 3 is a kind of structural representation of the structure of arc strip, and Fig. 4 is the lateral view of Fig. 3, and Fig. 5 is the profile of Fig. 3 along A-A.
In the accompanying drawing, 1 is circle body, and 2 is arc strip, and 3 is lower body, and 4 is the upper body, and 5 are the transition body, and 6 is longitudinal rib.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in Figure 1, 2, the utility model is the shield machine roller cutter circle, mainly comprises circle body 1, offers annular inner groovy on circle body 1 periphery, and soldering has carbide alloy rolling ring in the inner groovy, and the rolling ring is made up of a plurality of arc strips 2; The flute profile of inner groovy matches with arc strip 2, arc strip 2 Hardmetal materials manufacturing, and a plurality of arc strips 2 are brazed in the annular inner groovy of circle body 1 jointly, form high strength rolling ring.The external diameter of rolling ring is a bit larger tham or equals the external diameter of hobboing cutter circle body 1.As shown in Figure 4, the bottom of arc strip 2 is a lower body 3, and top is upper body 4, and the thickness of upper body 4 is greater than lower body 3, and middle is transition body 5, and transition body 5 adopts arc-shaped transition between upper body 4 and lower body 3; The upper side of upper body 4 adopts circular arc.Shown in Fig. 3,5, on two horizontal sides of the arc strip 2 of upper body 4, intermediate and lower body 3 parts, be respectively arranged with the longitudinal rib 6 of projection, two or more longitudinal rib 6 is set on each horizontal side, be convenient to soldering, guarantee that the weld seam thickness is even.
