DEVICE FOR PLATE MATERIALS PERFORATION

摘要

The frame structure (2) with a working hydraulic unit (3) is mounted on the basic braced structure (1) and the hydraulic unit (3) consists of two rows of hydraulic elements (4) of pre-stressing of compressive force with quick-action piercing heads (5). The working hydraulic unit (3) comprises collecting channels (6) and it is stiffened from above by a supplying and distributing hydraulic unit (7), which is connected to the frame structure (2). The mechanical-hydraulic stepper (9), which is connected to the basic braced structure (1), is also connected to the carrier device (10), which is equipped with adjustable points (10). Two side guides (14) and four side hydraulic clamps (15) are mounted on the basic braced structure (1). The mechanical-hydraulic clamps can be mounted instead of the adjustable points (12).<IMAGE>
