A rotary automatic feeding mechanism for double punching machines

Abstract

The invention discloses a rotary type automatic feeding mechanism with two punching machines. The rotary type automatic feeding mechanism with the two punching machines comprises a machine frame and a fetching mechanism and is characterized by further comprising two feeding mechanisms, the two punching machines, two detection plates, two blank detecting and positioning mechanisms and a main control machine, wherein the feeding mechanisms, the fetching mechanism and the detection plates are fixed to the machine frame; one feeding mechanism, one detection plate, one punching machine, the other detection plate, the other feeding mechanism and the other punching machine are sequentially fixed around the fetching mechanism in the clockwise direction; the two feeding mechanisms, the two detection plates and the two punching machines are symmetric with the center of the fetching mechanism; and the distances between the feeding mechanisms and the center of the fetching mechanism, between the detection plates and the center of the fetching mechanism as well as between the punching machines and the center of the fetching mechanism are the same. Blanks to be machined are positioned twice through positioning blocks above the feeding mechanisms and a mold sleeve outside a mold, and it is ensured that the blanks are accurately put in the machining position; and besides, photoelectric detectors on the punching machines can detect whether the blanks are put accurately or not, so that the effect that the mold is prevented from being damaged and safety during punching are further ensured.

Description

technical field [0001] The invention relates to a blank supply device for a punching machine, in particular to a rotary 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 th...
