Description

Technical Field

[0001] The invention relates to the technical field of copper tube production, in particular to an inner wall tube straightening device for an upward continuous casting copper rod crystallizer. Background Art

[0002] The inner wall tube of the upward continuous casting copper rod crystallizer is the key inner layer component of the crystallizer in the continuous casting copper rod production. It constitutes the main structure with the outer tube. With its good thermal conductivity, the copper liquid introduced into the crystallizer is cooled and solidified into a copper rod in the tube, and the smooth inner wall is conducive to the forming of the copper rod and the quality accuracy. If the raw materials for making the inner wall tube have uneven internal residual stress, the stress release in the subsequent processing will cause the tube to bend and deform. This situation will occur due to improper rolling process. Once the inner wall tube is bent, the copper liquid will flow unevenly in the crystallizer, affecting the solidification of the copper rod, causing its organizational structure to be uneven and defects, seriously damaging the quality and performance of the copper rod.

[0003] In the prior art, most metal tube straightening uses external straightening. The principle is to apply a corrective force from the outer surface of the metal tube to achieve straightening. However, the effect of this corrective force is relatively single, and it only acts on the outer surface of the tube, and cannot simultaneously stabilize and adjust the internal structure of the metal tube. After the external straightening is completed, the residual stress originally existing in the metal tube has not been effectively balanced and still remains in the tube. With long-term use or interference from some slight external forces during subsequent use, the metal tube is very likely to rebound and then return to a bent or deformed state. In this way, the effect achieved by the straightening is difficult to maintain for a long time, and secondary straightening operations are often required frequently, which will undoubtedly increase the corresponding cost and workload. Moreover, the external straightening method has limitations, and there is no way to accurately adjust the internal structure of the metal tube. Even if the external shape of the metal tube reaches a straight state after straightening, there is still a deviation in the concentricity between the inside and the outside. When such a metal tube is applied to a specific equipment, it will affect the forming of the copper tube, and the surface wear of the formed copper tube will be aggravated when the formed copper tube is drawn, etc., affecting the overall performance of the product.

[0004] Therefore, those skilled in the art provide an inner wall tube straightening device for an upward continuous casting copper rod crystallizer to solve the problems raised in the above background technology. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a device for straightening the inner wall tube of an upward continuous casting copper rod crystallizer. The device has the advantages of arranging an extrusion assembly, combining the contact of a rotating roller and the rotation of an inserted rod to achieve comprehensive straightening, and will not wear the inner wall of the inner tube. Straightening the inside and outside at the same time can make the tube wall bear force evenly, reduce stress concentration, delay fatigue damage, and be beneficial to the long-term stable use of the inner wall tube of the crystallizer, reduce the frequency of equipment renewal and maintenance, etc., and solves the problem that the existing technology mostly adopts external straightening of metal tubes and applies corrective force on the outer surface, but this method has a single effect and cannot stably adjust the internal structure. After straightening, the residual stress inside the metal tube is not balanced, and it is easy to rebound by slight external force or long-term use. The straightening effect is difficult to last, and frequent secondary straightening is required, which increases cost and workload. In addition, it is difficult to accurately adjust the internal structure by external straightening. Even if the outside is straightened, the concentricity of the inside and outside may still have deviations, which will affect the forming of the copper tube when applied to the equipment, and will also aggravate surface wear during drawing, affecting the overall performance of the product.

[0006] In order to achieve the above purpose, an extrusion assembly is set up, and then the roller contact and the insertion rod rotation are combined to realize comprehensive straightening without wearing the inner wall of the inner tube.

[0030] In summary, when the inner wall tube straightening device of the upward continuous casting copper rod crystallizer is used, the inner wall tube is placed between two rows of straightening rollers 2, and the outer part of the inner wall tube is straightened by the rotation of the straightening rollers 2. After the outer part is straightened, the inner wall tube will slide toward the direction close to the insertion rod 6, and the insertion rod 6 is inserted into the inner tube. When the inner wall tube is completely inserted into the outer surface of the insertion rod 6, the driving motor 9 is started to drive the driving gear 10 to rotate, and the driving gear 10 drives the insertion rod 6 and the roller through the meshing of the driven gear ring 11. 8 rotates inside the inner wall tube, and the insertion rod 6 rotates, driving the reciprocating screw 123 to rotate.

At this time, the inside of the boost chamber 121 is not in a boost state, and the strong pressure inside the boost chamber 121 is slowly discharged through the air outlet pipe 1212 until there is no large friction between the roller 8 and the inner wall of the inner wall tube.
