Description

Technical Field

[0001] This utility model relates to the technical field of rolling, specifically to a rolling mill for processing copper bushings. Background Technology

[0002] The rolling process in copper bushing manufacturing involves repeatedly rolling and annealing copper ingots to produce plates, strips, or foils with specific thicknesses and widths. This process utilizes the principle of plastic deformation in metals, repeatedly rolling copper strips using high-precision rolling mills, combined with annealing treatment, to achieve the required mechanical properties and dimensional accuracy of the copper material. The final product possesses excellent ductility, electrical conductivity, and bending resistance, and is widely used in electrical, construction, decoration, and aerospace fields.

[0003] According to Chinese Patent No. CN220837214U, a rolling mill for processing copper sleeves includes a table. Four legs are fixedly installed around the bottom of the table. Two connecting plates are fixedly installed on the lower surface of the table. Each connecting plate has a movable groove inside. A work plate is fixedly connected between the two connecting plates. Motor brackets are fixedly connected to both sides of the bottom of the work plate. A first motor is fixedly installed on the surface of each of the two motor brackets. Gears are fixedly connected to the output ends of each of the two first motors. A support column is slidably installed on one side of each of the two motor brackets. A toothed plate is fixedly installed on one side of each of the two support columns. Bearings and couplings are fixedly installed at the upper ends of the two support columns. A first rotating shaft and a second rotating shaft are fixedly installed inside the bearings and couplings, respectively. A roller is fixedly connected between the first rotating shaft and the second rotating shaft.

[0004] In the above scheme, the rolling of raw materials is achieved by extruding them with rollers, which still has the following disadvantages: when the rollers roll the raw materials, the edges of the raw materials may be irregular on both sides, requiring subsequent cutting, which reduces the efficiency of processing copper sleeve raw materials. Utility Model Content

[0005] The purpose of this invention is to provide a rolling mill for copper sleeve processing, in order to solve the problem that irregular edges may occur on both sides during rolling, requiring subsequent cutting and reducing the efficiency of copper sleeve raw material processing.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a rolling mill for copper sleeve processing, comprising a rolling roller, the rolling roller being rotatably disposed on the top surface of a mounting plate, a pressing roller being rotatably disposed above the rolling roller, two sliding openings being provided on the top surface of the mounting plate, two sliding folding plates being slidably disposed above the mounting plate, the two ends of the sliding folding plates being slidably disposed with the two sliding openings respectively, a sliding rod being fixed inside the sliding opening, two sliding holes being provided on one side of the sliding folding plate, the sliding rod being slidably inserted into the sliding holes, two adjustment openings being provided on the top surface of the mounting plate, connecting plates being fixed on both sides of the sliding folding plates respectively, a sliding screw being fixed on the bottom surface of the connecting plate, the sliding screw being slidably inserted into the adjustment opening, and a nut being threadedly connected to one end of the sliding screw passing through the adjustment opening.

[0007] Preferably, the top surface of the mounting plate is fixed with two fixing plates, and motors are fixed on the two opposite sides of the two fixing plates. The output shaft of the motor passes through the fixing plates and is fixed to one end of the rolling roller. A lifting plate is slidably arranged above the fixing plates, and the two lifting plates are rotatably arranged with the two ends of the pressing roller on their opposite sides.

[0008] Preferably, the top surface of the sliding folding plate is detachably provided with two heightening pads, the top surface of the heightening pads is provided with two fixing holes, the top surface of the sliding folding plate is provided with two threaded grooves, a fixing bolt is rotatably inserted into the fixing hole, and the bottom end of the fixing bolt passes through the fixing hole and is threadedly connected to the threaded groove.

[0009] Preferably, a fixing screw is fixed to the top surface of the fixing plate, and a through hole is opened on the top surface of the lifting plate. The fixing screw is slidably inserted into the through hole, and two nuts are threadedly connected to the fixing screw. The lifting plate is supported upward by the nuts below.

[0010] Preferably, a stabilizing rod is fixed to the top surface of the fixed plate, and two sleeve holes are opened on the top surface of the lifting plate, wherein the stabilizing rod is slidably inserted into the sleeve holes.

[0011] Preferably, a support column is fixed at each of the four corners of the bottom surface of the mounting plate, and an anti-slip pad is fixed at the bottom of the support column.

[0012] Compared with the prior art, a rolling mill for copper bushing processing that adopts the above technical solution has the following advantages:

[0013] Beneficial effects:

[0014] Before rolling the raw material for making copper sleeves, the workers apply force to two sliding folding plates, causing them to slide inside the sliding opening. During this sliding process, the distance between the two sliding folding plates changes. Then, when rolling the raw material, it is placed between the rolling roller and the pressing roller. The output shaft of the motor drives the rolling roller to rotate synchronously. The rotating rolling roller, in cooperation with the pressing roller, rolls the raw material. At this time, the two sliding folding plates have been adjusted to their positions on the mounting plate as required. During the subsequent rolling process, the elongation of the raw material is limited by the distance between the two sliding folding plates, restricting the width to a specific size. This also increases the neatness of the raw material on both sides after rolling, avoiding the need for secondary processing of the raw material edges and increasing the efficiency of copper sleeve raw material processing.

[0015] 2. To address the thickness of the calendered product, workers will install different numbers of heightening pads on the top surface of the sliding folding plate. Then, they will use fixing bolts to pass through the fixing holes and connect with the threads of the threaded grooves to fix the heightening pads on the top surface of the sliding folding plate. The thickness of the heightening pads will increase the height of the sliding folding plate, thereby limiting the extension range of calendered products of different thicknesses and increasing the applicability during calendering.

[0016] Third, when workers need to roll raw materials into finished products of different thicknesses, they will rotate the nut clockwise or counterclockwise, causing the nut to move up and down on the surface of the fixed screw. This allows them to adjust the height of the lifting plate above the fixed plate, thereby adjusting the distance between the rolling roller and the pressing roller to roll copper sleeve raw materials of different thicknesses, increasing the convenience of processing copper sleeve raw materials of different thicknesses.

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, a rolling mill for processing copper bushings includes a rolling roller 3, which is rotatably mounted on the top surface of a mounting plate 1. A pressing roller 5 is rotatably mounted above the rolling roller 3. Two sliding openings 7 are provided on the top surface of the mounting plate 1. Two sliding folding plates 8 are slidably mounted above the mounting plate 1. The two ends of the sliding folding plates 8 are slidably mounted to the two sliding openings 7 respectively. A sliding rod 9 is fixed inside the sliding opening 7. Two sliding holes 10 are provided on one side of the sliding folding plate 8. The sliding rod 9 is slidably inserted into the sliding holes 10. Two adjustment openings 15 are provided on the top surface of the mounting plate 1. Connecting plates 16 are fixed on both sides of the folding plate 8. A sliding screw 17 is fixed on the bottom surface of the connecting plate 16. The sliding screw 17 is slidably inserted into the adjustment port 15. A nut is threaded onto the surface of the sliding screw 17 that passes through the adjustment port 15. Two fixing plates 2 are fixed on the top surface of the mounting plate 1. Motors 6 are fixed on the two fixing plates 2 that are far apart from each other. The output shaft of the motor 6 passes through the fixing plate 2 and is fixed to one end of the rolling roller 3. A lifting plate 4 is slidably arranged above the fixing plate 2. The two lifting plates 4 that are close to each other are rotatably arranged with the two ends of the pressing roller 5.

[0024] In use, before rolling the raw material for making copper sleeves, the operator applies force to the two sliding folding plates 8, causing them to slide inside the sliding opening 7. During this sliding process, the distance between the two sliding folding plates 8 changes. Subsequently, when rolling the raw material, it is positioned between the rolling roller 3 and the pressing roller 5. The output shaft of the motor 6 drives the rolling roller 3 to rotate synchronously. The rotating rolling roller 3, in cooperation with the pressing roller 5, rolls the raw material. At this time, the two sliding folding plates 8 have been adjusted to their positions on the mounting plate 1 as required. During the subsequent rolling process, the elongation of the raw material is limited by the distance between the two sliding folding plates 8, restricting the width to a specific size. This also increases the neatness of the raw material on both sides after rolling, avoiding the need for secondary processing of the raw material edges and increasing the efficiency of copper sleeve raw material processing.

[0025] like Figure 1 and Figure 4As shown, the top surface of the sliding folding plate 8 is detachably provided with two heightening pads 11. The top surface of the heightening pads 11 has two fixing holes 12. The top surface of the sliding folding plate 8 has two threaded grooves 13. Fixing bolts 14 are rotatably inserted into the fixing holes 12. The bottom end of the fixing bolts 14 passes through the fixing holes 12 and is threadedly connected to the threaded grooves 13. Support columns 22 are fixed at the four corners of the bottom surface of the mounting plate 1. Anti-slip pads 23 are fixed at the bottom ends of the support columns 22.

[0026] In use, depending on the thickness of the calendered product, the staff will install different numbers of heightening pads 11 on the top surface of the sliding folding plate 8, and then use fixing bolts 14 to pass through fixing holes 12 and connect with the threads of threaded grooves 13 to fix the heightening pads 11 on the top surface of the sliding folding plate 8. The thickness of the heightening pads 11 increases the height of the sliding folding plate 8, thereby limiting the extension range of calendered products of different thicknesses and increasing the applicability during calendering.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, a fixing screw 18 is fixed on the top surface of the fixing plate 2, and a through hole 19 is opened on the top surface of the lifting plate 4. The fixing screw 18 is slidably inserted into the through hole 19. Two nuts are threaded on the fixing screw 18. The lifting plate 4 is supported upward by the nuts below. A stabilizing rod 20 is fixed on the top surface of the fixing plate 2, and two sleeve holes 21 are opened on the top surface of the lifting plate 4. The stabilizing rod 20 is slidably inserted into the sleeve holes 21.

[0028] In use, when workers need to roll the raw material into finished products of different thicknesses, they can rotate the nut clockwise or counterclockwise to move the nut up and down on the surface of the fixed screw 18, thereby adjusting the height of the lifting plate 4 above the fixed plate 2. This allows for adjustment of the distance between the rolling roller 3 and the pressing roller 5, which is used to roll copper sleeve raw materials of different thicknesses, increasing the convenience of processing copper sleeve raw materials of different thicknesses.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
