Feeding mechanism of automatic punching machine

Abstract

The invention discloses a feeding mechanism of an automatic punching machine. The feeding mechanism comprises conveying roller ways which are positioned on two sides of a lower die and driven by conveying motors mounted on a machine tool body, the conveying roller ways include a front roller way and a back roller way, the front roller way is positioned on the feeding side of the lower die, the back roller way is positioned on the discharging side of the lower die, and a sensing device is arranged at the tail end of the front roller way and is connected with the conveying motor. The feeding mechanism of the automatic punching machine has the advantages that since door sheets are conveyed through the conveying roller ways, different specifications of door sheets can be conveyed, and collision between the door sheets and an upper rail cannot be caused because of a high conveying speed; when the door sheets are close to the lower die, the sensing device can send a signal to the conveying motor after sensing the door sheets, and the door sheets can be guided into the lower die safely for punching through reduction of a rotating speed of the conveying motor, so that safer operation and high speed are achieved and improvement on production efficiency is benefited.

Description

technical field [0001] The invention relates to a punching device, in particular to a feeding mechanism of an automatic punching machine. Background technique [0002] At present, most of the doors in China are equipped with peepholes to observe the situation outside the door, because the peepholes allow people to observe the people or the environment outside the door, so that people can decide whether to open the door according to the actual situation, so as to prevent accidents Therefore, it is very necessary to install a cat's eye on the door; if you want to install a cat's eye on the door, you must process a cat's eye hole on the door; now there is a punching hole The machine base is provided with a track for transporting door panels, but its track is composed of upper and lower tracks sandwiched by two panels, and the gap between the upper and lower tracks forms a channel for door panels to pass through, so it is suitable for relatively Thin door panel conveying makes ...

If the speed is too fast, it will easily cause the door panel and the two panels forming the track to collide with each other, resulting in relatively low production efficiency
