On the cutter hub of hobboing cutter, and it is fixedly connected by the shaft shoulder and reinforcement retaining ring opened up on cutter hub.
The present invention it is a kind of for Suporting structure combination cutter ring Hob for cutting rock processing and manufacturing when, mainly pass through following step
The rapid installation to complete the combination cutter ring Hob for cutting rock:
S1: outer ring smooth surface cutter ring with groove is made using the relatively low hard alloy machining of hardness；
S2: routinely technique is slotted in smooth surface cutter ring outlet；
S3: along the two sides outer rim abrasion-resistant welding wire build-up wear-resistant alloy-layer of smooth surface knife outer ring groove；
S4: it is forged through Overheating Treatment with flat tooth on the groove of smooth surface cutter ring outer ring using the relatively high hard alloy of hardness
Flat land circle form the combination cutter ring；
S5: added in the smooth surface cutter ring outer ring groove two sides of the combination cutter ring of formation using built-up welding and tumble in wear-resistant alloy layer；
S6: knife is inserted in for cutter ring is combined using hot charge practice, then reinforcement retaining ring is installed and is fixed cutter ring is combined.
In general, through the invention it is contemplated above technical scheme is compared with the prior art, can achieve following has
Beneficial effect: a kind of combination cutter ring Hob for cutting rock for Suporting structure of the present invention, the flat land circle and smooth surface knife
The mutually chimeric combination cutter ring for forming integral type of circle, and in two side external surface build-up wear-resistant alloy-layer of smooth surface cutter ring groove, it reduces
Abrasion in cutter ring work, it is larger to improve the rock breaking capacity of hobboing cutter, improve the rock stratum drivage efficiency of Suporting structure.
