Plate assembly includes that lower flashboard body, lower knife body and lower sawtooth are constituted, and upper knife body and lower knife body are V-shaped in the horizontal plane, the angle of V-type
For α, the angle of cutter hub blade surface and horizontal plane is β in perpendicular for upper knife body and lower knife body, upper knife body bottom and cut
Sawtooth and lower sawtooth are installed, sawtooth end longitudinal profile end is vertical line segment, is formed with adjacent bevel surfaces blunt at the top of body
Angle, the brake application plate body and upper knife body are casting integrated molding, and it is be bonded that upper sawtooth and upper knife body pass through high-performance viscose glue, lower flashboard
Body and lower knife body are casting integrated molding, and lower sawtooth is be bonded by high-performance viscose glue with lower knife body.
Preferably, above-mentioned angle α and β are adjustable.
Preferably, the upper sawtooth and lower sawtooth are in same level, upper sawtooth and lower sawtooth are respectively provided with four.
It is fixedly connected preferably, engagement thread can be used with the connection of flashboard cutter hub in above-mentioned sawtooth.
For the shear ram of the utility model design during shearing drilling rod, the sawtooth on upper lower flashboard cutter hub cutting edge is first
First drilling rod is engaged, after quickly forming the surface defects such as groove, under the continuous action of external force, the surface defects such as groove will
Diffusion rapidly, this effectively accelerates the fracture of the tools such as drilling rod, then continues to squeeze up to fracture completely, to complete by cutter hub
The shearing work of the tools such as drilling rod, under the action of identical shearing external force, compared to the mode of traditional direct shearing, the Novel scissors
The shear ability for cutting flashboard geometric format is stronger, more efficient, under the action of identical thrust, direct is cut with cutter hub compared to traditional
The flashboard cut, efficiently shear ram shear ability at least improves 20%~40% for this, and further, upper sawtooth and lower sawtooth are designed
In same level, from left and right directions to drilling rod one from apply thrust, the shearing force of formation destroys more caused by drilling rod
Greatly.
