Perforating Tools TRIZ Cases

A lever trigger, wedge members, and a spring lock punch tips securely while enabling quick tool-free changes with less downtime.

A punch-and-die jamb tool creates accurate electric strike openings in metal door frames with less noise, damage, and installation time.

Wedge-shaped punch protrusions flank the weld zone to cut high-strength steel with lower residual stress, better surface quality, and longer punch life.

A removable cutting punch stays lodged in the pierced hole, reducing wear, easing retrieval, and protecting hole shape in high-strength sheet metal.

A motorized quick-release head lets this knockout punch driver make large sheet-material holes while staying compact and serviceable in confined spaces.

A transmission-shaft-driven sheet holder applies preload only during punching to keep thin sheets flat while reducing feed friction and damage.

A screwdriver-driven hydraulic pump replaces compressed air, delivering high riveting and pressing force in a compact, lower-complexity tool.

A transmission-shaft-driven sheet holder with hydraulic preload keeps thin sheets flat during dense perforation while reducing friction.

An engagement section on the punch enables stable extraction from high-strength multi-layer sheet metal without high retraction force or punch breakage.

A movable second die changes blank width in one stroke while arc-shaped sheet support maintains cutting accuracy and reduces bending.

A centering pin and spring-loaded punch remove spot weld slugs by impact, separating sheet metal panels without drill wear or metal damage.

A rotating shifting member replaces linear travel to retract the punch, cutting occupied space while maintaining punch press control.

Multi-sensor cutting data and CNN model updates improve abnormality diagnosis and processed product quality assessment.

Multiple counter tool bodies with different cutting gaps let one machining setup handle varying planar workpiece thicknesses with less tool change.

A synchronized striker and pressure-receive plate mechanism preserves punching force near 90° shaft rotation for thin and thick sheet press work.

Continuous slotting and trimming strokes cut longer sheet slots faster while improving edge quality and preventing material strip counter-sinking.

A pressure-increasing piston lets a hydraulic return valve open independently of fixed working pressure, improving handling of varied workpiece sizes and materials.

Adjustable inner and outer counter cutting edges help separate micro-jointed sheet parts, shorten cycle time, and handle larger workpieces.

A battery-powered hydraulic punch replaces cable-tethered drilling to form cable tray holes with less scrap dispersion and safer handling.

A clamped centering mechanism keeps a hole-making tool stable on pipes, preventing slippage and improving perpendicular hole accuracy.

A threaded engaging portion converts tangential force into controlled punch withdrawal, preventing breakage in high-force blanking of multilayer sheets.

A male-female blade jig punches coated resin bumpers without rotational tearing or burrs, keeping hole edges clean and appearance intact.

A motor-driven hydraulic piston lets a compact hand-held knockout punch create larger holes in sheet material without bulky external hydraulics.

Compression-shaped interchangeable razor blades cut dumbbell coupons from soft materials with repeatable geometry and low maintenance.

Dual spring bias and a breaking mechanism let the knockout pin support the workpiece during pressing, then cut push force to ease punch design.

Modified punch pin dimensions create deeper TORX socket flutes, preserving driver fit after zinc-flake coating buildup.
