Abstract
A metal pipe straightening machine comprises a drive mechanism and a straightening mechanism. The straightening mechanism adopts rotors for straightening, the straightening mechanism is divided into two groups, each group includes at least three rotors, the two groups are the same in rotor quantities, a moving route of material processing serves as the axis of symmetry, the two groups of rotors are in mirror symmetry, a control device, namely a scale adjusting plate, used for adjusting the inclined angle of the rotor is arranged behind each rotor, the distance between two corresponding rotors is controlled by the scale adjusting plates behind the rotors, and each rotor is driven through a universal joint. According to the metal pipe straightening machine, the universal joint is used for completing transmission; since each rotor is driven by one independent universal joint, and all universal joints in one group are controlled by one motor, the consistences of all rotor are guaranteed; owing to features of the universal joints, little deviation is produced when the rotors rotate, and accuracy of the straightening machine is improved greatly.
Description
Technical field
The present invention relates to metal tube manufacture field, relate in particular to a kind of metal tube straightener.
Background technology
At present, aspect the alignment for metal tube, the technology mostly adopting is to have pushed alignment by the rotary head subtend of many group rotations, but, at present domestic rotary head in the time carrying out alignment is all to complete transmission by chain, the transmission of every group of rotary head is all to start to drive backward second rotary head to rotate from first, and continue to drive next, during due to chain drive, kinetic energy can lose a part, so just cause the rotating speed of each rotary head inconsistent, the slight vibrations that produce during simultaneously due to chain drive also have slight deviation can cause rotary head to be rotated time, affect alignment precision.
Summary of the invention
The present invention aims to provide the metal tube straightener that a kind of precision is higher.
For realizing above-mentioned technical purpose, the invention provides following technical scheme, a kind of metal tube straightener, comprise driving mechanism and aligning mechanism, described aligning mechanism adopts rotary head to proofread and correct, aligning mechanism is divided into two groups, every group is at least provided with 3 rotary heads, the rotary head number of two groups is consistent, taking the moving line of rapidoprint as symmetry axis, these two groups of rotary head Mirror Symmetries, it is scale adjustment disk that the rear of each rotary head is equipped with for the control device of regulating rotary head tilt angle, spacing between corresponding two rotary heads is also controlled by the scale adjustment disk at rotary head rear, each rotary head is carried out transmission by a universal joint.
As preferably, described drive unit is motor, and all driving universal joints of every group of rotary head are all driven by a drive unit.
As preferably, described aligning mechanism is provided with 6 rotary heads altogether, every group of 3 rotary heads, and 3 driving universal joints of every group are by same Electric Machine Control.
As preferably, the angle between each rotary head rotary head is corresponding thereto 45 °-135 °.
As preferably, two corresponding rotary heads are mutually vertical.
As preferably, rotary head is made up of wolfram steel, is totally cylindrical, and mid portion diameter is less than the diameter of both sides.
The metal tube straightener of the present invention's design, transmission is completed by universal joint, because having independent universal joint, each rotary head completes transmission, and all driving universal joints of every group are all by same Electric Machine Control, and this has just ensured the uniformity of all rotary heads, the while is due to the characteristic of universal joint self, few deviation that produces when rotary head is rotated, greatly improved the precision of straightener, precision can have been controlled in 0.1mm from 0.05mm, efficiency is higher.
