Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and more specifically, to a copper strip polishing mechanism for the production of copper-aluminum alloy wire. Background Technology

[0002] Copper-aluminum alloy wire, also known as copper-clad aluminum alloy wire, is a type of conductor consisting of an aluminum core wrapped with a thin layer of copper strip. This structure combines the excellent conductivity of copper with the lightweight properties of aluminum, aiming to provide a cost-effective conductor material.

[0003] Currently, copper strips are typically used to directly coat aluminum wires, or the copper strips are cleaned before coating. However, because the surface of the copper strip is exposed, it is prone to oxidation. Ordinary cleaning cannot remove the oxide layer, which affects the conductivity of the coated copper-aluminum alloy wire and thus impacts product quality. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a copper strip polishing mechanism for the production of copper-aluminum alloy wire that can automatically polish copper strips and is applicable to copper strips of different thicknesses.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] The guide component and guide groove work together vertically to provide stable vertical guidance. Rotating the adjusting screw allows for raising and lowering of the guide component, which in turn raises and lowers the copper strip on the support, controlling the distance between the copper strip and the polishing part. This method is suitable for copper strips of different thicknesses. The adjusting screw also allows the top surface of the copper strip to be pressed against the polishing part for polishing, thus removing the oxide layer on the side of the copper strip covering the aluminum wire and ensuring the product quality of the copper-aluminum alloy wire. Because the adjusting screw and installation are threaded, the adjustment of the copper strip height is more precise.

[0019] The guide groove is formed between the mounting plate, the two guide plates, and the pressure plate; the adjusting screw is threaded onto the base plate.

[0020] Preferably, the pressure plate is threaded with a clamping screw, which is inserted into the guide groove and pressed against the guide member.

[0021] Preferably, the guide member has a groove on the side near the pressure plate; the end of the clamping screw located in the guide groove is provided with a pressure block that fits into the groove.

[0022] Preferably, the portions of the clamping screw and the adjusting screw located outside the guide groove are threaded with self-locking nuts.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] refer to Figure 1-4 A polishing mechanism for copper strip 6 used in the production of copper-aluminum alloy wire includes: a mounting base 1, a guide member 2, an adjusting screw 3, a bearing base 4, and a polishing assembly. The mounting base 1 is provided with a guide groove 11; the guide member 2 is vertically guided within the guide groove 11; the adjusting screw 3 is threaded onto the bottom of the mounting base 1 and connected to the guide member 2, used to adjust the height of the guide member 2; the bearing base 4 is located on top of the guide member 2 and is used to support the copper strip 6; the polishing assembly has a polishing component 5 located above the bearing base 4 for polishing the copper strip 6.

[0036] Understandably, the guide groove 11 is a component used to vertically guide the guide member 2. For example, it can be formed by opening it in the mounting base 1, or it can be formed by multiple plates, etc., but is not limited to these. The guide member 2 and the guide groove 11 have a shaft-hole mating structure. The guide member 2 can be a round rod structure, a square structure, etc., but is not limited to these. The adjusting screw 3 can be in contact with the guide member 2, or it can be rotatably connected to the guide member 2, etc. The bearing base 4 is a component that supports the copper strip 6. For example, it can be a plate structure or a structure similar to a transfer roller composed of multiple rollers, etc., but is not limited to these. The polishing component 5 can be an actively rotating polishing wheel, or it can be a polishing block that automatically polishes the copper strip 6 through automatic transfer, etc., but is not limited to these.

[0037] The guide 2 and guide groove 11 work together to provide stable vertical guidance. Rotating the adjusting screw 3 allows the guide 2 to be raised or lowered, which in turn raises or lowers the copper strip 6 on the bearing seat 4, thus controlling the distance between the copper strip 6 and the polishing part 5. This method is suitable for copper strips 6 of different thicknesses. The adjusting screw 3 allows the top surface of the copper strip 6 to be pressed against the polishing part 5 for polishing, which removes the oxide layer on the side of the copper strip 6 that covers the aluminum wire, ensuring the product quality of the copper-aluminum alloy wire. Since the adjusting screw 3 is threaded, the height of the copper strip 6 can be adjusted more precisely.

[0038] In some embodiments, the mounting base 1 includes: a mounting plate 12, two guide plates 13, a base plate 14, and a pressure plate 15. The two guide plates 13 are vertically and spaced apart on the mounting plate 12; the base plate 14 is disposed at the bottom of the two guide plates 13; the pressure plate 15 is detachably disposed on the side of the two guide plates 13 away from the mounting plate 12; wherein, a guide groove 11 is formed between the mounting plate 12, the two guide plates 13, and the pressure plate 15; and an adjusting screw 3 is threaded onto the base plate 14.

[0039] Understandably, the mounting plate 12 is the base component used to install the entire base. The guide plate 13, the base plate 14, and the mounting plate 12 can be integrally formed, or they can be welded or connected by screws, etc. The pressure plate 15 can be detachably installed by locking it to the guide plate 13 with screws, etc. The main function of the base plate 14 is to use the threaded adjustment screw 3, which can provide a fully enclosed or unenclosed plate structure for the bottom of the guide groove 11.

[0040] Thus, the adjusting screw 3 can be threaded onto the base plate 14; the detachable installation of the pressure plate 15 facilitates the disassembly and assembly of the guide component 2 inside the guide groove 11.

[0041] In some embodiments, a clamping screw 8 is threaded onto the pressure plate 15, and the clamping screw 8 passes into the guide groove 11 and presses against the guide member 2. Thus, after the position of the guide member 2 is adjusted by the adjusting screw 3, the clamping screw 8 can be tightened to lock the position of the guide member 2. Furthermore, a groove 21 is provided on the side of the guide member 2 near the pressure plate 15; a pressure block 81 that fits into the groove 21 is provided at one end of the clamping screw 8 located in the guide groove 11. Here, the groove 21 can be a square groove 21, a trapezoidal groove 21, etc., and the guide member 2 is adapted to the shape of the groove 21, but is not limited to this. Thus, through the cooperation of the pressure block 81 and the groove 21, the contact area between the adjusting screw 3 and the guide member 2 can be increased, improving the stability of the clamping of the guide member 2.

[0042] In some embodiments, the portions of the clamping screw 8 and the adjusting screw 3 located outside the guide groove 11 are threaded with a self-locking nut 9. In this way, the self-locking nut 9 can slightly lock the positions of the clamping screw 8 and the adjusting screw 3, thereby strengthening the stability of the guide member 2.

[0043] In some embodiments, the top of the support 4 is provided with a limiting groove 41 for limiting the copper strip 6. The limiting groove 41 is a component for limiting the copper strip 6. For example, it can be formed by recessing into the support 4, or by providing spaced limiting blocks 42 on the support 4, but it is not limited to these. Here, the width of the limiting groove 41 needs to be set to be slightly larger than the width of the copper strip 6. In this way, the limiting groove 41 can limit the copper strip 6, prevent the copper strip 6 from shifting during transmission, and ensure that the polishing part 5 can be stably polished on the copper strip 6.

[0044] Specifically, the limiting groove 41 consists of two spaced-apart limiting blocks 42, with two sets of the two limiting blocks 42 spaced apart. In this way, the two sets of limiting blocks 42 spaced apart can form a clearance groove in the middle, which can avoid the polished part 5 and prevent the polished part 5 from contacting the bearing seat 4.

[0045] In some embodiments, the polishing element 5 is a polishing wheel, and the polishing assembly also includes a motor with a power output end connected to the polishing wheel. Here, since connecting the motor to the polishing wheel is a conventional arrangement, the motor is not shown in the accompanying drawings. Thus, the copper strip 6 can be actively polished by rotating the polishing wheel with the motor.

[0046] In some embodiments, reference Figure 1The polishing mechanism also includes a housing 7, with through slots 71 on both sides for the copper strip 6 to pass through; the mounting plate 12 and the polishing parts 5 are both mounted on the inner wall of the housing 7. Here, the housing 7 can be a closed housing 7 with a door, or a housing 7 structure with an opening on one side, etc., but is not limited to these. Thus, the housing 7 can house and protect the internal polishing mechanism. Other straightening and traction mechanisms related to copper-clad aluminum can also be installed on the housing 7.

[0047] In some embodiments, a traction mechanism for pulling the copper strip 6 is also provided outside the housing 7. The traction mechanism can be a pressure roller or a turntable, etc., which are existing technologies and will not be described in detail here. In this way, the copper strip 6 can be driven to move through the traction mechanism, and the surface of the copper strip 6 can be continuously polished in conjunction with the polishing assembly.

[0048] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
