Description

Technical Field

[0001] The present invention relates to the technical field of punching machine loading and unloading, and specifically relates to an automatic loading and unloading device for a numerical control turret punching machine. Background Art

[0002] A numerical control turret punching machine is composed of a computer control system, a mechanical or hydraulic power system, a servo feeding mechanism, a tool magazine, a tool selection system, a peripheral programming system, etc. The numerical control turret punching machine is based on a machining program compiled by programming. The servo feeding mechanism sends the sheet material to the position to be processed. At the same time, the tool turret structure is controlled to quickly switch tools, and the hydraulic power system performs stamping according to the program to automatically complete the processing of workpieces.

[0003] Currently, during the automatic loading and unloading process of numerical control turret punching machines, most of them grab and convey the sheet materials by installing multiple suction cups on the conveying equipment, thereby realizing the loading and unloading operations. However, the traditional loading and unloading equipment is large and bulky, with a complex structure, not easy to disassemble, install, move, and only completes the conveying work during the loading and unloading process. When the sheet material is processed, due to factors such as the punching machine tool, part of the waste material is easily adhered to the sheet material. After unloading, it is necessary to manually shake or strike the sheet material to make the waste material fall off. This increases the operation process, is time-consuming and laborious, and when loading the sheet material, there is a lack of a cleaning component for the top side of the sheet material. When there are sundries on the sheet material that are not cleaned, the sheet material is likely to damage the punching machine tool during the processing, and at the same time, it also affects the processing quality of the sheet material.
