Abstract

The invention relates to an automatic feeding-type punch press which comprises automatic feeding devices. The automatic feeding devices are mounted on two sides of a die of the punch press in an alignment manner respectively. Each automatic feeding device comprises a support provided with a worktop on the top face; sliding seats are arranged on screw rod transmission mechanisms mounted on the worktops; feeding sliders are mounted on the sliding seats through guide sliding rails perpendicular to the screw rod transmission mechanisms; plate fixing devices are arranged above the feeding sliders; each feeding slider slides on the corresponding guide sliding rail through two feeding cylinders respectively arranged on two sides of the feeding slider; motors of the automatic feeding devices are controlled by a control system of an electrical control cabinet to drive the screw rod transmission mechanisms to enable the sliding seats to slide, and the feeding cylinders are utilized to control the feeding sliders to slide to complete automatic feeding of plates. The automatic feeding-type punch press is adopted to punch workpieces, the automatic feeding devices are simple in structure, small in occupied space and applicable to processing of various plates, and the die of the punch press is convenient to maintain and easy for workers to operate.
