Automatic multi-punch punching machine

Abstract

The invention relates to an automatic multi-punch punching machine which comprises a rack, a pipe feeding device, a female die device and a die head assembly. The die head assembly comprises punch assemblies, punch control assemblies, an upper pressing plate, lifting guide columns, a lifting plate, lifting screws, a guide plate, lower pressing guide columns, a lower pressing plate and a bottom plate, two sets of guide wheels are arranged on the bottom plate, and a punching position is formed between the two sets of guide wheels. The lower pressing plate, the guide plate and the lifting plate all slide along the lower pressing guide columns, the lifting screws are fixedly connected with the lifting plate and are in threaded connection with the lower pressing plate, the upper pressing plateslides along the lifting guide columns, and limiting steps movably connected with the upper pressing plate in a clamped mode are arranged at the top ends of the lifting guide columns. All the punch assemblies slide along the lifting plate, the guide plate and the lower pressing plate respectively and point to the punching position, all the punch control assemblies are installed on the upper pressing plate and movably matched with the corresponding punch assemblies, the female die device is installed on the rack and stretches into the punching position, the cost is low, and use is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of punching machines, in particular to an automatic multi-head punching machine. Background technique [0002] Punching machines are widely used in the processing and forming of mechanical parts, and the processing of these parts is often not a simple repetition of the same unit. In order to adapt to the processing of fine and diverse parts, it is usually necessary to use a multi-station punch. In the existing stamping process, a very high-priced turret-type CNC punch with a multi-station punch is often used, that is, punches of different stations It is installed on a rotatable shaft, but when this kind of punch is used, it needs to be calibrated to make the punch and the concave template precisely aligned, which is inconvenient to use, and this type of punch is difficult to produce. Therefore, it is generally expensive. If you do not use a brick tower CNC punching machine, you must frequently replace the p...

In order to adapt to the processing of fine and diverse parts, it is usually necessary to use a multi-station punch. In the existing stamping process, a very high-priced turret-type CNC punch with a multi-station punch is often used, that is, punches of different stations It is installed on a rotatable shaft, but when this kind of punch is used, it needs to be calibrated to make the punch and the concave template precisely aligned, which is inconvenient to use, and this type of punch is difficult to produce. Therefore, it is generally expensive. If you do not use a brick tower CNC punching machine, you must frequently replace the punch, which is extremely inconvenient to use.
