QD11-10 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‑gripping when burrs form on the sheet metal. Recommended for integration into production lines for rapid connection to customer workcells. Powered by compressed air, it operates quietly with no pollution. Features advanced pneumatic clutch technology. Shearing speed is significantly higher than conventional mechanical or hydraulic shearing machines. Failure rates are greatly reduced compared to traditional shearing machines. Crankshaft drive offers superior performance over conventional straight‑shaft drive. Employs four‑point supported rolling guides that eliminate support clearance; compared to three‑point roller systems, motion is smoother and more reliable, ensuring consistent shearing quality. Blade gap is adjusted manually or electrically—quickly and precisely. Both upper and lower blades are made from premium tool steel with four usable edges, extending service life. A centralized lubrication system minimizes the risk of machine damage caused by operator oversight or omission of lubrication.

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 four-point-supported rolling guide rail to eliminate support clearance; compared with three-point roller motion, this provides smoother and more reliable operation, ensuring cutting 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.
