The invention relates to an automatic
punching special
machine for an automotive glass guide rail. The automatic
punching special
machine for the automotive glass guide rail comprises a holding rack, a top circle rotary table is arranged on the holding rack through a driving device, fixed seats are arranged in the
peripheral direction of the top circle rotary table through mounting holes, the lower ends of the fixed seats are connected with lifting cylinders, and carriers are arranged on the upper end faces of the fixed seats; an inner-circle table is arranged on the central portion of the top circle rotary table, multiple sets of dies are arranged in the
peripheral direction of the inner-circle table, and oil hydraulic cylinders are fixed on the corresponding sets of dies through mounting plates; a workpiece unloading mechanical arm and a workpiece loading mechanical arm are arranged at the front end of the holding rack, a workpiece unloading
conveyor belt is arranged below the workpiece unloading mechanical arm, and a material feeding
conveyor belt is arranged below the workpiece loading mechanical arm; a workpiece ejector cylinder is further arranged on the inner-circle table, and the workpiece ejector cylinder is corresponding to a workpiece
workstation of the workpiece loading mechanical arm. By means of the automatic
punching special
machine for the automotive glass guide rail, complete
machining processes of feeding, clamping, punching, forming and unloading are achieved automatically, the excessive equipment occupation and the waste of human resources are effectively solved, and the production efficiency and the
machining precision are significantly improved.
