Problems solved by technology

Because the pipe bending arm needs a lot of power to start, but the existing power is not enough to make it bend under good conditions, and the space in the head of the pipe bending machine is very limited, so it is impossible to increase the power equipment, so this The structural pipe bender can only be limited to bending pipes with small diameters; in addition, when the rack is moving, there will be axial deviation due to the force, which not only consumes too much precious power, but also Reduced pipe bending accuracy

Abstract

The invention discloses a boosting driving device for a spindle of a bending pipe arm. The boosting driving device comprises a main gear which is fixedly mounted on the spindle, wherein a rack is meshed with the main gear; a driving gear is connected to a servo motor through a speed reducer; the driving gear is also meshed with the rack; a one-way cylinder is arranged at the tail end of the rack; and a piston rod of the one-way cylinder is connected to the tail end of the rack. The boosting driving device has the beneficial effects that the one-way cylinder is arranged at the tail end of the rack and the rack is simultaneously influenced by the acting forces of the servo motor and the one-way cylinder at the beginning of a bending process, thereby greatly increasing the power at the beginning of the bending process of the bending pipe arm and solving the problem that such a bending pipe machine can be used for only bending a small-bore pipe; the power transferring efficiency is promoted; the bending precision can be promoted; and the boosting driving device can be applied to a rotating bending pipe machine.

Description

technical field [0001] The invention relates to a drive device for a main shaft of a pipe bending arm in a rotary pipe bending machine. Background technique [0002] At present, a commonly used driving method for the main shaft of the pipe bending arm in the rotary pipe bending machine is: a main gear is fixedly installed on the main shaft, the rack and the main gear mesh with each other, the driving gear is connected with the servo motor through a reducer, and the driving gear Also meshes with the rack. The above-mentioned driving gears and racks are all arranged in the head of the pipe bender, and the reducer and the servo motor are installed on the housing of the head. When working, the servo motor drives the drive gear to rotate through the reducer, the drive gear drives the rack to move, and the rack drives the main gear and the main shaft to rotate, so as to achieve the purpose of pipe bending. Since the pipe bending arm needs a lot of power to start, and the existin...
