Description

TECHNICAL FIELD

[0001] The present application relates to a full-automatic bending machine die changing mechanism and a mounting method thereof. BACKGROUND

[0002] Metal material bending processing is one of the key forming processes in the fields of mechanical manufacturing, construction engineering, automobile industry, aerospace, etc., and is widely used in the production of structural parts, frames, pipes, decorative parts and other products. With the rapid development of manufacturing industry towards high efficiency, precision and intelligence, the market puts forward higher requirements for the automation level, processing precision, production efficiency and flexibility of bending processing.

[0003] At present, common bending processing equipment mainly includes manual bending machines, semi-automatic hydraulic or numerical control bending machines. Manual equipment relies on the experience of operators to complete bending through manual operation of levers or dials, which has low processing precision, poor consistency, high labor intensity, and safety hazards, and is only suitable for small batch, low precision or on-site temporary processing scenes. Semi-automatic and numerical control equipment to a certain extent realizes the program control of angle and position, and improves the repeatability. However, in the bending process, the die is the core process equipment to realize different bending radii, angles and workpiece shapes. The die of the traditional bending machine, whether manual, hydraulic or numerical control type, is usually designed as a single body and fixed on the workbench or slide of the equipment by bolts, pins or hydraulic clamping slots. When the production task needs to change the product specification, the corresponding die changing operation must be carried out, and the die changing is a heavy labor and technical work. The operator needs to use lifting equipment or manually carry the heavy die, disassemble and install multiple fasteners one by one, and roughly position and align. The whole process is time-consuming, which leads to low effective utilization rate of the equipment. In the small batch, multi-variety flexible manufacturing scene with frequent production change, the cumulative die changing time may be much longer than the actual processing time, which seriously reduces the overall production efficiency.

[0004] The storage, searching, transportation and clamping state management of the existing die are mostly in the stage of manual paper record or experience memory. It is easy to cause problems such as misuse of die, difficulty in searching, confusion of versions, etc. Moreover, it is impossible to quickly replace the die during processing, thereby delaying the processing progress.

[0005] Therefore, it is necessary to invent a full-automatic bending machine die changing mechanism and a mounting method thereof to solve the above problems. SUMMARY
