Abstract

A servo direct-driven harmonic drive spiral bending machine comprises two symmetrically arranged power portions. Output of the power portions is achieved through planetary roller screw mechanisms, and the power portions are connected with a sliding block of the bending machine. Each power portion comprises a permanent magnetic motor portion, a harmonic wave speed reduction portion and a roller screw portion; when permanent magnetic motors are powered up, rotors directly drive harmonic generators to rotate under the action of magnetic field force and accordingly staggered tooth motions are carried out between a flexible gear and a rigid gear, speed reduction and torque increase are achieved, motions output by the flexible gear drive output shafts to rotate, the front ends of the output shafts are provided with the planetary roller screw mechanisms, and accordingly the sliding block is driven to move up and down, and a plate is bent and formed through a die on the sliding block. The mechanical-electrical integration design is adopted, the structure is compact, and equipment reliability is high; a large reduction ratio can be achieved through harmonic gears, and large forming force is provided; by means of a computer and servo control, elasticity of the plate can be predicted, and the plate can be bent and formed accurately.

Description

technical field [0001] The invention belongs to forging punching and shearing equipment, in particular to a servo direct drive type harmonic drive spiral bending machine. Background technique [0002] When processing the plate, it is often necessary to bend the plate at a certain angle to meet the needs of practical applications. At present, the main sheet metal bending equipment is divided into mechanical type and hydraulic type. The mechanical bending machine usually uses a motor and a series of gear transmission systems to realize the up and down movement of the slider; the hydraulic bending machine uses a hydraulic cylinder and a series of Complex oil circuit control elements to realize the up and down movement of the slider. Bending machines play an important role in the iron and steel industry, especially in large iron and steel enterprises, which often require continuous and high-precision operation of bending machines. However, at present, due to the complexity of t...
