Description

Technical Field

[0001] The present application relates to the technical field of copper wire surface processing, and in particular to a copper wire stripping device. Background Art

[0002] Copper wire is a conductive material widely used in the electrical and electronics industries, enjoying widespread popularity due to its excellent conductivity, ductility, and corrosion resistance. However, due to copper's chemical properties and environmental influences, copper wire is susceptible to oxidation when exposed to air, forming a black oxide layer. This oxide layer not only affects the copper wire's appearance but also its electrical conductivity. Therefore, removing the oxide layer from the copper wire surface is a crucial step in copper wire production.

[0003] CN220740634U discloses a copper wire surface treatment device, which includes a base plate, the bottom of the base plate is fixedly connected to a support leg, the top of the base plate is fixedly connected to a support frame, a grinding adjustment component is arranged inside the support frame, and the grinding adjustment component includes a cylinder, a movable plate, a sliding sleeve, a first connecting rod, a second connecting rod and a slide plate, the inside of the support frame is fixedly connected to the cylinder, the piston rod of the cylinder is fixedly connected to the movable plate, the outer side of the movable plate is slidably connected to the sliding sleeve, one side of the sliding sleeve is respectively rotatably connected to the first connecting rod and the second connecting rod, and the inside of the support frame is slidably connected to the slide plate.

[0004] The above patent document aims to remove the black oxide layer on the surface of the copper wire after the annealing process. The method adopted is to grind the black oxide layer on the surface of the copper wire. However, in actual application, it is difficult to ensure that the surface oxide layer can be completely removed by grinding alone, because it is difficult for the grinding device to contact all surfaces of the round copper wire, and the copper wire will jump during grinding, resulting in part of the continuously transmitted copper wire not being able to be polished. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a copper wire stripping device, which mainly removes the surface oxide layer through two steps of grinding and stripping, and uses cutting fluid to clean the surface of the copper wire before stripping. On the one hand, it can remove grinding waste chips, and on the other hand, it can lubricate the stripping process. In addition, the copper chips are collected and recovered through a collection chamber connected to the stripping chamber, thereby reducing consumables and improving economic benefits and environmental protection factors.

[0015] The following is a clear and complete description of the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0016] Example 1

[0017] refer to Figures 1 to 3 A copper wire stripping device comprises a frame 1, a straightening unit 2 and a stripping unit 3 connected to the frame 1 in sequence; the straightening unit 2 is used to straighten the copper wire and grind the oxide layer of the copper wire; the stripping unit 3 comprises a spray chamber 301, a stripping chamber 302 and a collecting chamber 303 connected in sequence; the spray chamber 301 is provided with a nozzle 31 for spraying cutting fluid onto the oxide layer of the copper wire; the stripping chamber 302 is provided with a stripping mechanism 32 for stripping the oxide layer of the copper wire; one side of the stripping chamber 302 is an open side a and the open side a is connected to the collecting chamber 303, and the copper chips stripped by the stripping mechanism 32 enter the collecting chamber 303 from the open side a.

[0018] In this embodiment, it should be noted that an external annealing device is arranged at the rear end of the device, that is, after the copper wire passes through the device to remove the oxide layer, it immediately enters the annealing device for annealing treatment. As for the structure of the annealing device, please refer to another patent document of our company - Publication No.: CN219326807U, Subject Name: A Copper Wire Annealing Device.

[0019] In actual use, the copper wire first passes through the straightening unit 2 to polish the surface oxide layer and straighten it. Then it enters the spray chamber 301, where the nozzle 31 cleans the polished waste. Then it enters the stripping chamber 302, where the copper wire oxide layer is stripped by the peeling mechanism 32, and the copper chips enter the collection chamber 303. It should be noted that the premise of peeling is that a margin of approximately 1mm in diameter must be reserved when producing the copper wire. The part stripped by the peeling mechanism 32 is this 1mm margin.

[0020] This embodiment mainly removes the surface oxide layer through the two steps of grinding and peeling, and uses cutting fluid to clean the surface of the copper wire before stripping. On the one hand, it can remove grinding waste chips, and on the other hand, it can lubricate the stripping process. In addition, through the collection chamber 303 connected to the stripping chamber 302, the copper chips pass through the open side a into the knife collection chamber 303 for centralized recovery, thereby reducing consumables and improving economic benefits and environmental protection factors.

[0021] In this embodiment, specifically, the straightening unit 2 includes a tensioning wheel 21, a grinding wheel 22 and a limiting wheel group arranged on the frame 1 in the front and rear; one side of the grinding wheel 22 is provided with a driving mechanism 26 for driving its own rotation; the tensioning wheel 21 is used to tighten the copper wire.

[0022] More specifically, the limiting wheel assembly includes a first limiting wheel 23 and a second limiting wheel 24; the first limiting wheel is slidably connected to the frame via a lifting mechanism, and the second limiting wheel is fixed to the frame. The first limiting wheel 23 is slidably connected to the frame 1 via a lifting mechanism 25, and the second limiting wheel 24 is fixed to the frame 1.

[0023] In actual application, the lower edge of the tensioning wheel 21 should be slightly lower than the upper edge of the grinding wheel 22, and the grinding wheel 22 should be arranged horizontally with the second limiting wheel 24, and then the first limiting wheel 23 is adjusted by the lifting mechanism 25 to make the copper wire completely limited. It should be further explained that the tensioning wheel 21, grinding wheel 22, first limiting wheel 23 and second limiting wheel 24 are all V-shaped rollers.

[0024] More specifically, the structure of the lifting mechanism 25 is a hand-cranked screw lifting structure. Since this structure is well known to those skilled in the art, it will not be described in detail in this embodiment. However, it should be noted that those skilled in the art can simply replace it with an electric, hydraulic or other lifting structure within the scope of protection of this embodiment.

[0025] As a preferred embodiment of the present invention, the peeling mechanism 32 includes a first peeling knife 321 and a second peeling knife 322 arranged in front and back; the first peeling knife 321 and the second peeling knife 322 both have an annular cutting surface, and the diameter of the annular cutting surface of the first peeling knife 321 is larger than the diameter of the annular cutting surface of the second peeling knife 322. Under the above design, the two-step peeling can effectively reduce the pressure on the peeling knife, thereby increasing the service life of the first peeling knife 321 and the second peeling knife 322. In this embodiment, the specific structure of the peeling knife is not limited, because there are many peeling knife structures in the art, such as the peeling cone structure described in Publication No. CN208189964U or Publication No. CN205752952U.

[0026] As a further preferred embodiment of this embodiment, the stripping chamber 302 is provided with a liquid inlet 3021 and a liquid return port 3022. The nozzle 31 is connected to an external liquid storage device via a pipe via the liquid inlet 3021. The liquid return port 3022 is located at the bottom of the stripping chamber 302 and is connected to the external liquid storage device. This design allows for continuous recycling of the coolant, thereby reducing production costs.

[0027] In this embodiment, preferably, the stripping unit 3 further includes an isolation chamber 304 provided between the spray chamber 301 and the collecting chamber 303 ; the isolation chamber 304 is used to prevent copper chips from entering the spray chamber 301 .

[0028] Under the above-mentioned preferred embodiment, the isolation chamber 304 effectively prevents copper chips from accidentally entering the spray chamber 301 and causing the liquid return port 3022 or an external liquid storage device to be blocked.

[0029] In this embodiment, a first wire feed trough 110 is preferably provided between the straightening unit 2 and the spray chamber 301, a second wire feed trough 120 is provided between the spray chamber 301 and the isolation chamber 304, and a third wire feed trough 130 is provided between the isolation chamber 304 and the stripping chamber 302. The copper wire is sequentially transported in a straight line through the first, second, and third wire feed troughs 110, 120, and 130. In practical applications, the widths of the first, second, and third wire feed troughs 110, 120, and 130 should be designed based on the diameter of the copper wire, and are preferably designed to be exactly equal to the diameter of the copper wire to reduce vibration of the copper wire. With this further preferred embodiment, the copper wire is transported in a straight line through the first, second, and third wire feed troughs 110, 120, and 130 into the stripping mechanism 32, effectively improving processing quality and increasing the coaxiality of the copper wire.

[0030] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and intent of the present application, and that the scope of the present application is defined by the claims and their equivalents.
