JW31 H Frame Single Crank Power Press

H frame structure ensures higher rigidness and strength

The JW31 straight side single crank power press machine series features a meticulously engineered H-frame structure, renowned for its exceptional rigidity and strength. Crafted from high-grade steel plates, the welded H-frame body undergoes annealing treatment followed by sandblasting, effectively relieving welding stress and creating an optimal surface for durable painting. The press ram moves smoothly within the robust frame, while all critical components—including the motor, clutch, and lubrication system—are seamlessly integrated into the compact design. This harmonious integration not only ensures precise performance but also enhances the machine's aesthetic appeal, making it a reliable and visually appealing solution for demanding metalworking applications.

Eight faces slide guides with higher precision

The JW31 straight side single crank power press machine series incorporates an advanced H-frame design featuring a precision-engineered ram with 8-face slide guides, ensuring consistent movement along the machine's center axis for unparalleled accuracy. The cast iron ram undergoes CNC machining to achieve micron-level precision, while extended bronze plates are strategically fixed to the press body. This innovative construction, combined with a dedicated grease lubrication system between the bronze plates and slide gibs, delivers smooth operation, reduced wear, and extended service life. Integrating seamlessly with the machine's previously highlighted H-frame structure, annealing treatment, and compact component integration, this design optimization enhances overall rigidity, performance, and reliability for demanding metalworking applications.

Easy maintenance and operation

1. The JW31 straight side single crank power press machine integrates a globally certified wet clutch system, designed for minimal maintenance with semi-annual lubricant oil replacement. Equipped as standard with a hydraulic overload protection system, this press features a user-friendly reset mechanism via a control panel switch, enabling full operational readiness in just one minute.

2. A flat motor is strategically positioned on the press ram's back, working in tandem with an internal worm gear system to facilitate precise shut height adjustments. This functionality is seamlessly controlled through buttons and switches on the T-stand, ensuring effortless and accurate slide positioning.

3. The machine also incorporates an automatic central lubrication system, powered by an electric pump that efficiently distributes grease from the tank to all lubrication points. This comprehensive design, combining the H-frame's rigidity, precision-guided ram, and advanced components, delivers exceptional performance, reliability, and ease of operation for demanding metalworking applications.
