Product Features and Applications
High strength and impact resistance, withstands impacts from logs, branches, and other raw materials without easily bending or deforming
The pressure plate bears the weight of the cutting blade, protecting it, reducing chipping and breakage, and extending its service life
Mainly used on the cutter rollers or discs of large drum chippers and disc chippers
Product Details
01.
The throwing knife pressure plate and throwing knife are perfectly matched, preventing the throwing knife from suddenly flying out and detaching from the blade groove, thus avoiding safety accidents
02.
The pressure plate has standard bolt positioning holes, making throwing knife replacement simple and convenient without repeated calibration
03.
If grooves deeper than 1mm appear on the mating surface, the throwing knife cannot be evenly pressed, and the throwing knife pressure plate is considered unusable

FAQ
1)What causes frequent deformation and bending of the pressure plate?
A: ①Insufficient strength of the pressure plate material
②Uneven stress on the fastening bolts
③Excessive instantaneous impact load from large logs, burls, or hardwoods
2) Why do the pressure plate bolts frequently loosen, and why does the cutter clearance fluctuate?
A: ①High-speed vibration of the equipment, and lack of anti-loosening measures for ordinary threads
②Wood chips and debris on the bottom surface of the pressure plate, the back of the fly cutter, and the contact surface of the cutter holder
③Low bolt strength grade (below 8.8)
3) How to choose between a long, integral pressure plate and segmented, small-piece pressure plates?
A: Choose a long, integral pressure plate for high-power, heavy-duty production; choose segmented pressure plates for small to medium-sized equipment and for cost-effective maintenance
4)If grooves appear on the pressure plate due to wear, is it okay to replace only the cutter without replacing the pressure plate?
A: If the pressure plate has grooves, it is not recommended to use it for a long time if only the fly cutter is replaced
5)What is the normal service life of a set of pressure plates?
A: Heat-treated alloy steel standard pressure plate, clean cork stable operating conditions: 6000-10000 hours
6)What malfunctions will occur if the pressure plates on both sides of the same cutter have inconsistent thicknesses?
A: ①Uneven clamping force on the left and right sides of the flying knife, causing slight blade wobble during operation.
②Excessive thickness of one side of the pressure plate causes excessive local stress on the flying knife, making it prone to chipping and breakage
