Tính năng nổi bật

Compact progressive die for electrical contacts: 21 mm strip, 9 mm pitch. Two rows of holes are pierced first, then square parts are blanked at the end of the strip. Rotate the animated 3D model right on this page.

• A narrow 21 mm strip with two rows of pierced holes first, then square parts blanked at the end; 18 punches and 6 inserted dies in a compact die set.
• 21 mm wide strip with a 9 mm pitch. The animated 3D model shows the die opening and closing and the strip advancing one pitch per cycle.
• A spring stripper clamps the strip flat before the punches cut and strips it off the punches as the die opens; the springs compress with the stripper travel.
• Guided by 4 pillars Ø25; a press stroke of about 30 mm keeps the pillars engaged in their bushes throughout the cycle.
• Cutting and forming parts in SKD11 tool steel hardened to 58–62 HRC; shoes and holder plates in S50C to keep cost down; standard screws, dowels, pillars, bushes and springs.
• Order to your drawing: send the part drawing, material and thickness, volume and press data, and ZINITEK will propose the strip layout and die design.
