Description

Technical Field

[0001] This utility model relates to the field of copper rod production technology, and in particular to a rolling mill for copper rod production. Background Technology

[0002] In the continuous rolling process of copper rods, multi-pass rolling mills are typically used to continuously roll high-temperature copper billets to gradually reduce their cross-sectional dimensions, ultimately forming round or near-round copper rods of the desired specifications. Traditional rolling production lines often employ rolling mills arranged in a single direction, such as entirely horizontal or entirely vertical. This unidirectional rolling has a significant drawback: when the rolls apply pressure to the copper rod in a single direction, although the rod is compressed in the vertical direction, it inevitably undergoes widening deformation in the horizontal direction. This widening effect accumulates continuously in multiple rolling passes, making it difficult to control the cross-sectional shape of the copper rod and obtain an ideal circular profile and precise dimensional tolerances. The widened copper rod not only affects the geometric accuracy and surface quality of the final product but may also lead to difficulties in subsequent wire drawing processes, increased wire breakage rates, and the generation of more scrap, reducing material utilization and production efficiency. Furthermore, adjusting the roll spacing to accommodate different specifications of copper rods in existing rolling mills is often cumbersome and has limited precision, affecting production flexibility and product consistency. Meanwhile, the frictional heat generated during the rolling process and the high temperature of the copper rod itself require effective lubrication and cooling, but traditional methods may have problems such as low lubrication and cooling efficiency or cross-contamination of media.

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation.

[0032] Example

[0033] like Figures 1-5 As shown:

[0034] A rolling mill for producing copper rods, comprising:

[0035] Box base 1; an upper cover 11 is rotatably provided on the box base 1; the side wall of the box base 1 is provided with a feed inlet 12 and a discharge outlet 13;

[0036] Rolling mill assembly 2; the rolling mill assembly 2 is disposed within the housing 1; the rolling mill assembly 2 includes a vertical rolling mill 21 and a horizontal rolling mill 22; the vertical rolling mill 21 is provided with a first pressing channel 23; the horizontal rolling mill 22 is provided with a second pressing channel 24;

[0037] The vertical rolling mill 21 and the horizontal rolling mill 22 are staggered within the housing 1, and the first pressing channel 23, the second pressing channel 24, the feed inlet 12, and the discharge outlet 13 are strictly aligned on the same horizontal straight line. This arrangement allows the copper rod to be alternately subjected to vertical and horizontal rolling forces during continuous rolling. The widening deformation caused by rolling in one direction is effectively compressed back by subsequent rolling in the vertical direction, and vice versa. This alternating rolling significantly suppresses the cumulative widening effect in a single direction, making the cross-section of the copper rod closer to an ideal circle, greatly improving the dimensional accuracy, geometry, and surface quality of the product, and providing high-quality billets for subsequent wire drawing processes.

[0038] The feed inlet 12, the first compression channel 23, the second compression channel 24 and the discharge outlet 13 are located on the same horizontal straight line;

[0039] Lubrication system 3; the lubrication system 3 includes a lubrication inlet pipe 31 and a lubrication outlet pipe 32 disposed outside the housing 1; the lubrication inlet pipe 31 passes through the housing of the housing 1 and communicates with the rolling mill assembly 2 inside the housing 1;

[0040] The bottom of the rolling mill assembly 2 is also provided with an oil outlet pipe; the oil outlet pipe passes through the housing of the box seat 1 and is connected to the lubricating liquid outlet pipe 32.

[0041] Cooling system 4; the cooling system 4 includes an emulsion inlet pipe 41 disposed outside the housing 1 and an outlet trough located at the bottom of the housing 1; the emulsion inlet pipe 41 passes through the housing 1 and surrounds the first compression channel 23 and the second compression channel 24.

[0042] A dedicated lubrication inlet pipe 31 supplies lubricating oil to the rolling mill assembly 2, and the lubricating oil is recovered through the oil outlet pipe and the lubrication outlet pipe 32. The lubrication points are concentrated in the transmission parts.

[0043] A specially designed emulsion feed pipe 41 directly delivers the cooling emulsion to the area surrounding the first pressing channel 23 and the second pressing channel 24, directly cooling the rolls and high-temperature copper rods. Waste liquid is discharged through the bottom outlet tank.

[0044] This physical isolation design effectively prevents cross-contamination between the lubricating oil and the coolant emulsion, ensuring that their respective properties are maintained: the lubricating oil retains its lubricating properties, and the coolant maintains its cooling efficiency. Targeted supply improves lubrication and cooling efficiency, reduces consumption, extends the life of the rolls and transmission components, and simultaneously guarantees the surface finish of the copper rod.
