Description

Technical Field

[0001] The utility model relates to the technical field of oxygen-free copper production, in particular to an immersion-coated oxygen-free copper rolling mill. Background Art

[0002] An oxygen-free copper rod refers to a copper rod material with an oxygen content of less than 20 ppm. Oxygen-free copper rods usually have a bright appearance, so they are often called bright copper rods. Oxygen-free copper rods are pure copper materials without oxygen and any deoxidizer residues, and are mostly used for processing and manufacturing conductive materials for power transmission and signal transmission. In the prior art, oxygen-free copper rods are generally prepared by the up-drawing method and the impregnation method, among which: the impregnation method is a casting method in which a seed rod is impregnated in a furnace and solidified into shape.

[0003] In order to ensure the oxygen content during oxygen-free copper production, rolling is usually carried out in a protective atmosphere. The existing two-roll rolling mill adjusts the roll gap offline, and the maximum adjustment amount is mostly within 1.5 mm. Moreover, offline production is required, and the adjustment time is long, which has a great impact on production. When producing multiple specifications, the mechanical structure needs to be changed, resulting in low output and unstable quality, reducing production efficiency; on the other hand, there is no separation between the gear drive and the rolls in the rolling mill, and oil and water are mixed during use, which will cause the gears to rust, resulting in large rust losses of the equipment after shutdown, and is not conducive to the later operation of the equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problems that the existing two-roll rolling mill cannot adjust the roll gap online and the mixing of oil and water is likely to cause equipment damage, and provide an immersion-coated oxygen-free copper rolling mill.

[0036] The following uses specific specific examples to illustrate the implementation mode of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0037] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0038] Embodiment

[0039] As Figures 1 to 7 shown, a dip-coating oxygen-free copper rolling mill includes a hollow box body 1, and the hollow box body 1 is enclosed by a base 101, a box body 102, and an upper cover 103; an oil passage 600 is arranged inside the base 101 and the upper cover 103, and the oil passage 600 is used to inject lubricating oil into the hollow box body 1. Specifically, the inlet of the oil passage 600 is located on the side wall of the upper cover 103, and the outlet of the oil passage 600 points to the internal transmission mechanism. The closed box body isolates the entry of water and protects the gears from water corrosion, and sufficient lubrication improves the service life of the bearings and gears.

[0040] The rolled piece is disposed through the hollow box body 1. The rolled piece includes a main shaft 6, and the main shaft 6 is rotatably disposed in the hollow box body 1 through a first bearing member 4 and a second bearing member 7. Specifically, the first bearing member 4 includes a first seat body 41 and a first bearing 42 sleeved inside the first seat body 41, and the first bearing 42 is a tapered surface bearing. The second bearing member 7 includes a second seat body 71 and a second bearing 72 sleeved inside the second seat body 71, and the second bearing 72 is a self-aligning bearing. By using a self-aligning bearing below and a tapered roller bearing above to limit and fix the main shaft 6, the main shaft 6 can bear a greater radial force to meet long-time rolling, and the tapered surface bearing can better adjust the bearing oil gap and improve the service life of the internal mechanism.

[0041] The upper end of the main shaft 6 passes through the hollow box body 1 and is sleeved with a rolling roll 9. Specifically, a tapered sleeve 92 is further disposed between the rolling roll 9 and the main shaft 6, and a fixing sleeve 91 is sleeved at the top end of the main shaft 6. By using the tapered sleeve 92 to expand and tighten and the fixing sleeve 91 to be positioned by a flat key for transmission, it is prevented from slipping and idling during production.

[0042] In this solution, two rolled pieces are provided, namely a first rolled piece 100 and a second rolled piece 200. A rolling gap is formed between the rolling rolls 9 at the upper parts of the first rolled piece 100 and the second rolled piece 200.

[0043] In order to adjust the rolling gap, an adjusting sleeve body 5 is further provided. Specifically, the adjusting sleeve body 5 includes a first eccentric sleeve 51 fixedly sleeved on the first bearing member 4 and a second eccentric sleeve 52 fixedly sleeved on the second bearing member 7. Specifically, the main shaft 6 is eccentrically inserted into the eccentric sleeve. When the eccentric sleeve rotates, the main shaft 6 rotates eccentrically. An arc-shaped connecting arm 53 is disposed between the first eccentric sleeve 51 and the second eccentric sleeve 52, and an arc-shaped meshing section 54 is disposed on the surface of the arc-shaped connecting arm 53. Specifically, the arc-shaped meshing section 54 is preferably an arc-shaped worm gear structure.

[0044] On the other hand, in order to drive the arc-shaped meshing section 54 and control the rolled piece to deflect, an adjusting member 2 is further provided. The adjusting member 2 includes a rotating shaft 21 horizontally penetrating through the inside of the hollow box body 1. One end of the rotating shaft 21 passes through the hollow box body 1 and is sleeved with a coupling 20, and the coupling 20 is connected to an external high-torque servo motor. The other end of the rotating shaft 21 is limited and disposed on the side wall of the hollow box body 1 through a first bearing seat 24. A first threaded sleeve 22 and a second threaded sleeve 23 are sleeved on the rotating shaft 21, and the first threaded sleeve 22 and the second threaded sleeve 23 are arranged in the reverse direction. The first threaded sleeve 22 meshes with the arc-shaped meshing section 54 on the first rolled piece 100. The second threaded sleeve 23 meshes with the arc-shaped meshing section 54 on the second rolled piece 200.

[0045] In this solution, the adjusting member 2 is specifically a worm with opposite tooth directions. The two opposite threaded sleeves are respectively engaged with the arc-shaped meshing sections 54 on the first rolling member 100 and the second rolling member 200. Driven by the adjusting member 2, due to the use of an eccentric sleeve for connection, while ensuring that the center of the rolling gap remains unchanged, the distance between the first rolling member 100 and the second rolling member 200 from the rolling gap is reduced or increased, thereby realizing the function of changing the wire of multi-specification copper rods without stopping the machine. It should be noted that: in this solution, the threaded sleeve can be a sleeve in the sense of transmission, or a threaded section directly engraved on the shaft.

[0046] In this solution, the adjusting member 2 can also be replaced by two threaded rods with opposite directions. The positive and negative rotation screw rods are used to adjust the positive and negative rotation worm wheels to enlarge and reduce the roll gap without changing the rolling center. The maximum roll gap can reach 15 mm, which is much larger than the 1.5 mm roll gap amount in the industry, achieving the purpose of passing a 16 - thick rod without disassembling the rolling mill components and passing the wire.

[0047] To realize the rotation of the rolling member, a driving member is also provided which penetrates through the hollow box body 1 and contacts the rolling member to drive the rolling member to rotate; the driving member includes a middle shaft 81, and the middle shaft 81 is rotatably and limitedly arranged in the hollow box body 1 through a second bearing seat 82 and a third bearing seat 84; a transmission tooth member 83 is sleeved on the middle shaft 81.

[0048] Specifically, two sets of driving members are provided, namely a first driving member 400 and a second driving member 300; the transmission tooth members 83 of the first driving member 400 and the second driving member 300 are meshed with each other; the middle shaft 81 of the first driving member 400 passes through the hollow box body 1 and a drum-shaped tooth 401 is sleeved on it. A driven tooth member 63 is sleeved on the rolling member through a first limiting sleeve 61 and a second limiting sleeve 62; the driven tooth member 63 of the second rolling member 200 is meshed with the transmission tooth member 83 of the second driving member 300; the driven tooth member 63 of the first rolling member 100 is meshed with the transmission tooth member 83 of the first driving member 400. When in use, the power output end drives the first driving member 400 to rotate through the drum-shaped tooth 401. Under the transmission of the transmission tooth member 83, at this time, the first rolling member 100 and the second driving member 300 rotate. Since the driven tooth member 63 is meshed with the transmission tooth member 83 of the second driving member 300, at this time, the main shaft 6 of the second rolling member 200 rotates, driving the rolling roll 9 to rotate, and finally realizing the opposite rotation of the two rolling rolls 9, thereby achieving the purpose of rolling the copper rod.

[0049] Specifically, in this solution, the first bearing seat 24, the second bearing seat 82, and the third bearing seat 84 at least include a bearing and an installation sleeve, wherein the inner ring of the bearing is sleeved on the inner side wall of the installation sleeve, assisting the rotation of the shaft body and limiting the radial displacement of the shaft body at the same time.

[0050] In order to cool the rolling rolls during the rolling process, a cooling water spraying mechanism 500 is further provided on the surface of the hollow box body 1. The cooling water spraying mechanism 500 includes a pipeline and nozzles arranged on the pipeline. Further, in order to prevent the cooling water from entering the interior of the hollow box body 1, a seal 3 is sleeved on the main shaft 6, and the seal 3 is located at the connection between the main shaft 6 and the upper wall of the hollow box body 1.

[0051] The above embodiments only represent the specific implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
