The output shaft of the servo motor is connected to the first servo electric cylinder, the second servo electric cylinder, the third servo electric cylinder and the fourth servo electric cylinder through a synchronous belt. Piston rod connections for four servo electric cylinders. The pure electric servo numerical control bending machine provided by the present invention has the characteristics of high bending precision, large bending force, energy saving, and no pollution.

Description

technical field [0001] The invention relates to the technical field of bending machines, in particular to a pure electric servo numerical control bending machine. Background technique [0002] Bending machine is a kind of mechanical equipment commonly used by mechanical equipment manufacturers, mainly used for sheet metal parts processing. Now the rapid development of various industries, the production of various electrical boxes and aluminum curtain walls and a wide variety of communication and entertainment tools, the output is huge. Such as: all kinds of handheld phones: Game boy, PSP, NDSL, GBA; all kinds of mobile phones: economical mobile phones, business mobile phones, smart mobile phones, camera mobile phones, game mobile phones, music mobile phones, etc. The shells of these products all have common characteristics: they are all sheets with thin thickness and small external dimensions (length and width), require high bending precision, and pursue low workpiece cost....

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the bending machine mainly adopts the electro-hydraulic servo numerical control bending machine, and the hydraulic device is used for bending, which has the advantage of large bending force, but the processing accuracy is not high, and the hydraulic device cannot effectively adjust the upper and lower dies of the bending machine. The speed of pressing is low, and the bending production efficiency is not high; moreover, the hydraulic device needs to use hydraulic oil, the operating oil temperature is high, there are overheating, leakage, and the failure rate is high; secondly, the motor and oil pump of the hydraulic device In the process of operation, the noise is loud and the energy consumption is large

Compared with the electro-hydraulic CNC bending machine, the pure electric servo CNC bending machine has the characteristics of high precision, and overcomes the technical defects of the hydraulic device. However, the current pure electric servo CNC bending machine, due to the limitation of the motor power , has the defects of small torque and low bending force, which also affects product processing
