Automatic punching machine

Abstract

The invention discloses an automatic punching machine. The automatic punching machine comprises a machine tool main body, and a lower die is fixedly mounted in the central position of the lower part of the machine tool main body; an upper die is arranged right above the lower die; rollgangs used for conveying door panels are arranged in the positions, on the two sides of the lower die, of the machine tool main body; the rollgangs are driven through a conveying motor; the conveying motor is a variable frequency motor; a sensing device is arranged at the ends, close to the lower die, of the rollgangs in the feeding direction; and the sensing device is connected with the conveying motor. According to the automatic punching machine, the door panels are conveyed through the rollgangs, so that the door panels of different specifications can be conveyed, the conveying speed is relatively high, and impact of the door panels and an upper rail is prevented; and the sensing device is arranged, when the door panels are close to the lower die, the sensing device sends a signal to the conveying motor after sensing the door panels, the conveying motor is decelerated through frequency conversion,the door panels can be safely introduced onto the lower die to be punched, working is safer, speed is higher, and production efficiency is improved.

Description

technical field [0001] The invention relates to a punching device, in particular to 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 it difficult to carry d...

[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 it difficult to carry door panels of different specifications, and its conveying speed is relatively slow. 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
