This punching machine is designed for the side plate and keel of building aluminum formwork with a cross-section width of 80-600mm and more than 100*120 C slots. It features strong versatility and easy interchangeability, accommodating rib heights of 63.5mm and 65mm simultaneously. The machine body is heat-treated to eliminate internal stress, ensuring sufficient strength and rigidity. It uses a hydraulic station from a leading domestic brand and Schneider electrical components for stable and durable performance.

Operated by hydraulic pressure and a four-link mechanism, it ensures synchronized operation of the sliding block and punching needle during punching, achieving a punching diameter of 16.5mm with a hole distance of 50mm and 58 holes. It includes end positioning devices and allows for customized grinding tools as per customer requirements. The stroke adjustment bolts and travel switches provide convenient adjustment of the effective working stroke and travel, respectively. The blanking needle is guided by a back material plate for precise center alignment with the die core, ensuring burr-free punching holes and prolonging the blanking needle's service life. The compact hydraulic system design saves space and incorporates 40 valve sets to enhance production efficiency, achieving a punching completion time of 6 seconds. It offers free disassembly of the punching needle for efficient hole spacing changes and utilizes a special guide for precise hole placement in profiles.
