Automatic feeding mechanism of double punching machines

Abstract

The invention discloses an automatic feeding mechanism of double punching machines. The automatic feeding mechanism comprises a frame, a loading mechanism, a taking mechanism and a main controller, and is characterized by further comprising two punching machines, two thickness measurers and blank detection positioning mechanisms; the metal thickness detectors and the loading mechanism are both fixed on the frame; the taking mechanism is positioned rightly above the loading mechanism; the two ends of the frame are respectively connected with the two punching machines; the punching machines are provided with the blank detection positioning mechanisms; the metal thickness detectors are positioned in the middle positions of the punching machines and the loading mechanism; the metal thickness detectors can detect the thickness of blanks sucked on the taking mechanism so as to judge the number of the sucked blanks; and in the process of the taking mechanism conveying the blanks to the punching machines, the number of the blanks is detected to prevent the damage of molds. In addition, when the blanks are put in the molds, photoelectric detectors on the punching machines can detect if the blanks are placed precisely, so that such problems as mold damage and punching safety are further guaranteed.

Description

technical field [0001] The invention relates to a blank supply device for a punching machine, in particular to an automatic feeding mechanism for a double punching machine. Background technique [0002] A punch press is a stamping press. It is widely used in national production. For punching conventional blanks that are independent of each other into workpieces with specific shapes, workers or manipulators generally put the workpieces into the punch press one by one, but for large-volume workpiece processing, workers or manipulators Putting the workpiece into the punch press will be very inefficient, so it is particularly important to design an automatic feeding mechanism. First of all, to realize automatic feeding, the most important problem is how to make the raw materials be placed in the processing position accurately every time, that is, put the blank into the mold, and after placing the blank, the blank cannot be placed sideways, tilted or otherwise. Due to the tigh...
