QD11-4 Series Pneumatic Bottom Shear

Unlike traditional shearing machines that cut from top to bottom, this machine uses a bottom‑up cutting action, which prevents scrap and belt‑hooking when burrs form on the sheet metal. Recommended for integration into production lines for rapid connection with customer workgroups. Powered by compressed air, it operates quietly, cleanly, and without pollution. Features advanced pneumatic clutch technology. Shearing speed is significantly higher than conventional mechanical or hydraulic shearing machines. Failure rates are substantially reduced compared to traditional models. Crankshaft drive outperforms traditional straight‑shaft drive. Employs three‑point support rolling guides to eliminate bearing clearance and ensure shearing quality. Blade gap is adjusted manually or electrically—quickly and precisely. Both upper and lower blades are made of high‑quality tool steel with four usable edges, extending service life. A centralized lubrication system minimizes machine damage caused by operator oversight or failure to lubricate.

Technical Parameters

Unlike traditional shearing machines that cut from top to bottom, this machine uses a bottom‑up cutting action, which prevents scrapes and snags on the conveyor belt when burrs form on the sheet metal being cut.

Recommended for use with production lines, enabling rapid integration into customer workgroups.

The power source uses compressed air, resulting in low noise and clean, pollution-free operation.

Advanced pneumatic clutch technology

The cutting speed is significantly higher than that of traditional mechanical shearing machines and hydraulic shearing machines.

Significantly reduces the failure rate compared to traditional shearing machines.

Crankshaft drive is superior to conventional straight-shaft drive.

It employs a three-point-supported rolling guide rail to eliminate support clearance and ensure shearing quality.

Manual or electric adjustment of blade clearance, fast and accurate;

The upper and lower blades are made of high-quality tool steel and feature four cutting edges, extending their service life.

Centralized lubrication system, which to the greatest extent prevents machine damage caused by operators forgetting or neglecting to lubricate.
