Slitting Machines TRIZ Cases
- Ductile Steel Cup Absorbs Impact on PCD Bit
A ductile steel receiving cup absorbs impact forces on polycrystalline diamond bits, preventing tip fracture during concrete milling operations.
- Bit Holder Shank Radial Deflection for Interchangeable Bore Retention
Elongate slots in a cylindrical bit holder shank allow radial deflection, resolving retention reliability versus adaptability contradictions.
- Clearing Element for Milling Depth Accuracy
A pivoting clearing element with curved edges clears ground material before the movable side plate contacts the surface.
- Pick Tool Brazing Interface Design for Wear Resistance
Segmented planar sub-surfaces on the non-planar interface improve join consistency and wear resistance while reducing manufacturing complexity.
- Wireless Wear Sensor Coupling for Tunnel Boring Machine Tool Heads
A wireless coupling module connects wear sensors to tunnel boring machine tool holders, enabling rapid head replacement without physical electrical plugs.
- Cutting-bit Holder Block Cavity Design for Tool Access
A cutting-bit holder block features a side cavity extending from the interior to the bottom mounting portion.
- High-Pressure Air Burst Dust Mitigation for Mining Lenses
Pneumatic air jets clear optical surfaces on rigs, resolving the trade-off between cleaning efficiency and equipment safety.
- Rotatable Tool Holder on Pivoted Arm for Heading Machine
A rotatable tool holder mounted on a pivoted arm adjusts disc tool orientation to vary cutting profile heights and widths.
- Degradation Pick Hammer Element Impact Distribution
Integrally formed hammer element on a conical frustum body distributes impact forces to extend service life against premature wear.
- Chisel Holder with Angled Support Surfaces for Mining
Segmented angled support surfaces reduce acting torques and prevent screw loosening under alternating stress in high-infeed mining operations.
- Mining Plow Height-Adjustable Roof Carrier
Height-adjustable roof cutting bit carrier anchors at variable positions on the plow base to enable rapid reconfiguration of the mining assembly.
- Bit Removal Device Front-Side Extraction Mechanism
Front-side extraction eliminates back-access constraints and noise pollution during frequent bit replacement.
- Milling Drum Tooth Retainer Mechanism
Interlocking retainer features in overlapping drum recesses replace welding to eliminate cutter bit replacement downtime.
- Eccentrically Driven Disc Cutter for Hard Rock Excavation
Oscillating disc cutters mounted on a heavy arm apply tensile forces to break hard rock, reducing required excavation force and power consumption.
- U-Shaped Guide Piece With Locking Recess for Coal Plough
A replaceable U-shaped guide piece uses a central recess and locking mechanism to secure the component within a mining plough claw.
- Bit Holder Tire Portion Deflects Milling Particles
An enlarged tire portion on a bit holder deflects milling particles to protect the steel block from premature wear and damage.
- Composite Milling Tool Holder Supporting Area
A composite milling tool holder integrates a rear supporting area to stabilize the tool replacement device during maintenance operations.
- Arcuate Edge Cutting Element with Rotating Teeth
Rotating teeth on an arcuate base cut through dissimilar planes to reduce wear and extend cutting drum service life.
- Hard Face Structure Wear Retardation
A hard face structure fused to a steel substrate enhances wear resistance through composite phases, resolving reliability and complexity trade-offs.
- Segmented Bit Shank Tapered Interference Fit Ejection Prevention
A segmented bit shank with a tapered mediate segment creates radial interference contact within the base block bore.
