Abstract
Description
Technical Field
[0001] The invention relates to the technical field of metal pipe straightening, and more particularly to a metal pipe straightening device. Background Art
[0002] After the metal pipe is processed and formed, or after a period of use, due to its slender structural characteristics, it is often bent and deformed due to force or external factors, and needs to be corrected with the help of straightening equipment to restore the surface flatness. Currently common straightening machines usually apply extrusion pressure to the metal pipe through two upper and lower straightening rollers to achieve the straightening effect. However, traditional straightening machines are usually designed for metal pipes of fixed diameters, and their roller spacing cannot be flexibly adjusted, resulting in only being applicable to metal pipes of a single specification. In addition, this type of equipment only has a straightening function and cannot remove rust on the surface of the metal pipe at the same time. For metal pipes of different diameters, it is often necessary to replace straightening machines of different specifications or matching rust removal equipment, resulting in insufficient equipment compatibility, cumbersome operation, and low efficiency. Summary of the invention
[0003] The object of the present invention is to provide a metal pipe straightening device to solve the problems raised in the above background technology.

[0008] Preferably, the plurality of longitudinal straightening groups, the transverse straightening device located in the middle of the longitudinal straightening groups and the conveying mechanism are installed in a cabinet.
[0009] Preferably, the plurality of longitudinal straightening groups include a first longitudinal straightening group, a second longitudinal straightening group and a third longitudinal straightening group, and the first longitudinal straightening group, the second longitudinal straightening group and the third longitudinal straightening group are provided with upper and lower rows of longitudinal straightening rollers, and the upper and lower rows of longitudinal straightening rollers are located on the same line in the vertical direction.
[0010] Preferably, the first longitudinal straightening group, the second longitudinal straightening group and the third longitudinal straightening group are driven by a first motor, a second motor and a third motor respectively;
[0011] The third longitudinal straightening group is linked with the transmission mechanism through gears, is respectively installed on a fixed frame, and is driven by a third motor.
[0012] Preferably, the first longitudinal straightening group, the second longitudinal straightening group and the third longitudinal straightening group can be adjusted to different roller distances by installing upper and lower rollers with different spacings;
[0013] The upper roller and the lower roller are both provided with arc-shaped grooves.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. The present invention provides an adjustable spacing structure between the upper and lower rollers so that the rollers can adapt to metal pipes of different diameters. The straightening operation can be completed without changing the equipment, thereby improving the compatibility and application range of the equipment and meeting the production needs of pipes of various specifications.
[0019] 2. The present invention realizes adaptive contact with the surface of the metal pipe by installing a friction block with a tightening spring on the floating bearing. It can not only provide auxiliary straightening function in the process of correcting slight bending of the metal pipe, but also remove rust and attachments on the surface of the metal pipe, so that straightening and rust removal are completed simultaneously, which reduces the complexity of the process, improves work efficiency, and avoids the increase in time and cost caused by changing equipment or adding additional processes.
[0020] 3. The present invention provides a replaceable clamping mechanism, which can quickly replace the appropriate clamping components according to the metal pipes of different diameters, ensuring that the metal pipes are evenly stressed during the correction process. The clamping mechanism can stably fix the metal pipe and allow it to rotate around its own axis when working, so that the metal pipe can be corrected at multiple angles and in all directions when passing through multiple correction components such as upper and lower rollers and friction blocks, thereby avoiding the problem of local stress concentration that may be caused by traditional fixed straightening methods, significantly improving the uniformity and adequacy of the straightening effect, and ensuring the overall straightness and flatness of the metal pipe.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Working principle: The roller pitch of the longitudinal straightening roller is adjusted according to the required diameter of the metal tube. The servo motor 13 drives the clamping device 12 to rotate around its own axis. The first motor 9 and the second motor 10 respectively drive the first longitudinal straightening group 3 and the second longitudinal straightening group 4 to operate. The metal tube is stably fixed by the clamping device 12 and allowed to rotate around its own axis. Then, under the conveyance of the transmission roller, it enters from the first longitudinal straightening group 3, is conveyed to the second longitudinal straightening group 4 in the horizontal direction, and then enters the transverse straightening device 6. The friction block in the transverse straightening device 6 is in seamless contact with the metal tube. After passing through the transverse straightening device 6, the metal tube enters the third longitudinal straightening group 5. The third motor 11 drives the third longitudinal straightening group 4 to operate. The metal tube enters the conveying device 7 under the conveyance of the transmission roller, and is then removed and stored by the output device 8.
[0034] use Figure 1 The metal tube straightening equipment has good metal tube straightening effect. The equipment can accommodate metal tubes of different diameters by adjusting the roller distance between the upper and lower rollers, effectively solving the problem that the existing straightening machine cannot straighten metal tubes of different diameters. Similarly, by setting a number of floating bearing mounting seats in the transverse straightening device, there are tightening springs on the mounting seats, and friction blocks are set on the tightening springs. The adaptive contact between the friction blocks and the surface of the metal tube can not only provide auxiliary straightening function in the process of correcting the slight bending of the metal tube, but also remove rust and attachments on the surface of the metal tube, so that straightening and rust removal are completed simultaneously, reducing the complexity of the process.
