Description

Technical Field

[0001] This utility model belongs to the field of cold rolling mill technology, specifically a cold rolling mill for copper alloy tubes. Background Technology

[0002] The cold rolling mill for copper alloy tubes is a specialized piece of equipment for the cold working of copper alloy tubes. Through a periodic rolling process, using the combination of rolls and mandrels, the tubes are reduced in diameter, wall thickness, and deformed to achieve uniformity. This equipment is widely used in electrical, electronic, shipbuilding, and automotive industries, and is particularly suitable for the blanking production of copper alloy tubes that have rapid work hardening and poor plasticity. It can replace the traditional hot extrusion process, enabling energy-efficient and continuous disc production. It is a key piece of equipment for improving precision and reducing costs in the manufacturing of copper alloy tubes. The existing patent (publication number: CN208866148U) describes a cold rolling mill for copper alloy tubes. This cold rolling mill can process copper alloy tubes of different lengths and can effectively adjust the processing depth. However, this cold rolling mill does not have surface cleaning capabilities, and a lot of rust and impurities will remain on the outer surface of the copper alloy tubes, which will affect the integrity of the cold-rolled products and thus reduce their production quality. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a cold rolling mill for copper alloy tubes, which effectively solves the problem that the existing cold rolling mills do not have surface cleaning capabilities, and that a lot of rust and impurities remain on the outer surface of the copper alloy tubes, which will affect the integrity of the cold-rolled products and thus reduce their production quality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cold rolling mill for copper alloy tubes, comprising a worktable, with support legs fixedly installed on both sides of the bottom of the worktable, an installation frame fixedly installed at one end of the top of the worktable, and an installation cylinder fixedly installed at the other end of the top of the worktable. A feeding hopper is fixedly installed at the bottom of the installation cylinder. A servo motor is fixedly installed on one side of the top of the worktable via a support frame. A lower roller is provided in the lower part of the installation frame, and an upper roller is provided in the upper part of the installation frame. A cleaning ring is provided inside the installation cylinder. A transmission component is provided at the output end of the servo motor. The transmission component is connected to the lower roller, the upper roller, and the cleaning ring. When the servo motor is running, it outputs power to the lower roller, the upper roller, and the cleaning ring through the transmission component, causing the lower roller, the upper roller, and the cleaning ring to rotate.

[0005] Preferably, the transmission assembly includes a drive sprocket, which is fixedly mounted on the output end of the servo motor. A first shaft is fixedly mounted on one side of the drive sprocket, one end of which extends into the interior of the mounting frame and is fixedly connected to the upper roller. A second shaft is fixedly mounted on one end of the upper roller, one end of which extends into the exterior of the mounting frame and is fixedly mounted on an upper gear. A lower gear is meshed with the lower part of the upper gear. A third shaft is fixedly mounted on one side of the lower gear, one end of which extends into the interior of the mounting frame and is fixedly connected to the lower roller. One end of the lower roller is rotatably connected to the inner wall of the mounting frame.

[0006] Preferably, a driven sprocket is provided on one side of the driving sprocket, and one side of the driven sprocket is rotatably connected to the top of the worktable via a positioning seat. A chain meshes between the driven sprocket and the driving sprocket. A driving bevel gear is fixedly installed on the other side of the driven sprocket, and a driven bevel gear meshes with one side of the surface of the driving bevel gear. A transmission gear is fixedly installed on one side of the driven bevel gear. The sides of the transmission gear and the driven bevel gear that are far apart from each other are rotatably connected to the top of the worktable via a rotating seat.

[0007] Preferably, one side of the transmission gear extends into the interior of the mounting cylinder and is meshed with an external gear ring. A rotating ring is fixedly mounted on one side of the external gear ring. Two slip rings are fixedly mounted on the surface of the rotating ring. Two annular grooves are formed on the inner wall of the mounting cylinder. The two slip rings are slidably mounted inside the two annular grooves. The interior of the rotating ring is fixedly connected to the cleaning ring.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator passes one end of the copper alloy material to be processed through the mounting frame and inserts it between the upper and lower rollers. Then, the servo motor is started to drive the drive sprocket to rotate. When the drive sprocket rotates, it drives the upper roller to rotate through the first shaft. The upper roller drives the lower gear to rotate through the upper gear on the second shaft. The lower gear drives the lower roller to rotate through the third shaft, thereby performing cold rolling processing on the copper alloy material and moving the copper alloy material at the same time. When the drive sprocket rotates, it drives the driven sprocket to rotate via a chain. The driven sprocket then drives the driven bevel gear to rotate via the drive bevel gear. The driven bevel gear, in turn, drives the external gear ring to rotate via the transmission gear. The external gear ring, in turn, drives the cleaning ring to rotate via the rotating ring. The rotating ring, in turn, causes two slip rings to slide inside two annular grooves, increasing the stability of the rotating and cleaning rings during rotation. The cleaning ring continuously cleans the surface of the copper alloy material as it rotates, giving this cold rolling mill excellent surface cleaning capabilities. It can effectively remove residual rust and impurities from the outer surface of the copper alloy tube, preventing them from affecting the processing of the cold-rolled material and thus improving production quality.
