Metal-Working Drilling Tools TRIZ Cases
- Planar Rake Fluted Drill Bit for Better Chip Removal
Planar cutting faces with helical flutes improve chip removal and cutting efficiency while keeping drill bits manufacturable from cylindrical stock.
- Stainless Self-Drilling Screw Cold Forming Without Heat Treatment
Multi-stage cold forming work-hardens a stainless self-drilling screw, enabling steel-sheet penetration without heat treatment or bimetallic construction.
- Stainless Self-Drilling Screw Preforming for Thick Steel Penetration
Contour-edge preforming and cold work hardening let a stainless self-drilling screw penetrate steel sheets over 1.5 mm without heat treatment.
- Rotary Swaging Cam Tool for Precise Helical Outer Contours
A multi-stage cam tool forms precise helical outer contours by rotary swaging, cutting cost and avoiding separate strengthening steps.
- Connecting Element Groove Forming With Radial-Axial Shifting
Short forming bodies and axial shifting create closed longitudinal grooves with lower force, less die wear, and simpler production.
- Wired Drill Pipe Repeaters for Logging-While-Tripping Data Readout
Distributed repeaters store logging-while-tripping data during disconnected tripping, enabling surface readout and fast faulty segment verification.
- Connecting Element Forming with Single-Die Locking Groove Embossing
A single die with radially movable forming bodies creates entrainment surfaces and locking grooves while avoiding twisting, downtime, and bore scoring.
- Connecting Element Forming with a Single Die to Prevent Twisting
A single die with radially movable forming bodies creates drive surfaces and locking grooves while preventing twisting and cutting production cost.
- Oilfield Drill Pipe Upset Forging with Continuous Induction Heating
Continuous induction heating and auxiliary re-heating prevent rapid cooling, reducing production cycle time for oilfield drill pipes.
- Casing Bit Cutting Element Bond Strength Control
Laser-weldable metal alloy layers bond superhard cutting elements to casing bit bodies for controlled detachment during drilling operations.
- Forging Device Helical Blade Back Pressure Plate
Integrating the back pressure plate with the die blade simplifies structure and prevents unfilled portions in twisted forged articles.
- Monolithic Cutting Tool Shank and Fluted Portion
A monolithic cutting tool combines an injection molded shank with an extruded fluted portion for distinct material properties.
- W-Shaped Flute Milling Cutter Chip Evacuation
Split path grinding creates W-shaped flute cross sections that maximize chip evacuation volume while maintaining tooth strength for high-flute cutters.
- Forming Closed Longitudinal Grooves in Tool Shanks
Plastic deformation closes longitudinal grooves without machining, eliminating material waste and reducing manufacturing cycle time.
- Non-round Grinding for Drill Tip Supporting Chamfers
Non-round grinding integrates supporting chamfer formation into a single pass, reducing process complexity and improving concentric running.
