Abstract
The utility model provides rock tunnel(ling) machine point sword hob-cutter structure.The cross section of 1 blade of hobboing cutter cutter ring 2 is sharp blade type, contacts tread 2mm, 10 ° of sharp sword both sides angle, 21 ° of blade angle.It is sharp blade type because the utility model uses the cross section of hobboing cutter cutter ring blade, contact area reduces, and reduces frictional force and resistance, improves drivage efficiency, extends cutter life, reduces cost.It is suitable to be used as rock tunnel(ling) machine point sword hobboing cutter.
Description
Technical field
The utility model provides a kind of structure of rock tunnel(ling) machine hobboing cutter cutter ring, specifically rock tunnel(ling) machine point
Sword hob-cutter structure.
Background technology
Rock tunnel(ling) machine routine hobboing cutter cutter ring blade is to justify blade type, and blade contact area is big when hobboing cutter passively rotates, friction
Power and resistance are larger, and drivage efficiency is not high, reduce hobboing cutter service life.
The content of the invention
In order to reduce hobboing cutter cutter ring frictional force and resistance, cutter life is improved, the utility model provides tunnel digging
Enter machine point sword hob-cutter structure.By reducing cutter ring blade reduced cross-sectional, contact surface reduction frictional force and resistance are solved the structure
The technical problem of rock tunnel(ling) machine hobboing cutter drivage efficiency and service life.
The utility model solves the scheme that is used of technical problem：
The cross section of 1 blade of hobboing cutter cutter ring 2 is sharp blade type, contacts tread 2mm, 10 ° of sharp sword both sides angle, 21 ° of blade angle.
Good effect, is sharp blade type because the utility model uses the cross section of hobboing cutter cutter ring blade, and contact area reduces,
Frictional force and resistance are reduced, drivage efficiency is improved, extends cutter life, reduces cost.Suitably as rock tunnel(ling) machine point sword
Hobboing cutter is used.
Brief description of the drawings
Fig. 1 is the utility model blade schematic diagram.
In figure, 1. hobboing cutter cutter ring, 2. blade.
Specific embodiment
According to the figure, the cross section of 1 blade of hobboing cutter cutter ring 2 is sharp blade type, contacts tread 2mm, 10 ° of sharp sword both sides angle, sword
21 ° of portion's angle.
The characteristics of the utility model：
The cross section of hobboing cutter cutter ring blade is sharp blade type, and contact surface diminishes, and contact point resistance diminishes, and frictional force reduction is carried
The drivage efficiency of hobboing cutter high.Because frictional force is small, hobboing cutter cutter ring tipping and abrasion can be reduced, extend making for hobboing cutter cutter ring
Use the life-span.
Claims (1)
1. rock tunnel(ling) machine point sword hob-cutter structure, it is characterized in that：Hobboing cutter cutter ring（1）Blade（2）Cross section is sharp blade type, contact edge
2mm wide, 10 ° of sharp sword both sides angle, 21 ° of blade angle.
