Tin-plating device for copper-clad steel wire

Abstract

A tin-plating device for a copper-clad steel wire. By providing a tin-plating structure, an electromagnetic coil is used to push a magnetic block to enable a sliding column to slide inside a sliding sleeve, and this causes a pressing block to descend to press the copper-clad steel wire into a tin bath such that the copper-clad steel wire is submerged below the surface of molten tin, thereby achieving better tin plating for the copper-clad steel wire. As the pressing block drives the copper-clad steel wire to be submerged below the surface of the molten tin, heat from the molten tin is conducted via the sliding column and sliding sleeve to heat a memory spring. This allows the copper-clad steel wire to always remain submerged below the surface of the molten tin, thereby achieving a superior tin plating effect.

Description

A tinning device for copper-clad steel wire TECHNICAL FIELD

[0001] The present application relates to the technical field of copper-clad steel wire production equipment, and particularly relates to a tinning device for copper-clad steel wire. BACKGROUND

[0002] Copper-clad steel wire is a bimetallic composite material that combines the excellent conductivity and corrosion resistance of copper with the high strength of steel. Copper-clad steel wire is mainly used in electrified railways, lightning protection grounding systems, communications, electronic component leads, and other fields. With the rapid development of the electronics industry, in order to improve the weldability of electronic components and materials and reduce costs, a tin layer with good weldability is plated on the lead of electronic components (i.e., copper-clad steel wire). When tinning the copper-clad steel wire, the entire surface of the copper-clad steel wire is tinned, or the end of the copper-clad steel wire is tinned.

[0003] However, the tin liquid on the surface of the copper-clad steel wire is prone to form wire drawing at the tinned portion due to natural gravity and other reasons. These wire drawings can affect the appearance of the copper-clad steel wire after solidification.

[0004] As disclosed in Chinese Patent CN115044850A, a tinning device for copper-clad steel wire is provided. A pair of tinning knives are arranged in the rotating groove. The inner cavity of the limiting rod is provided with an expansion slot. The outer surface of the threaded ring is provided with an expansion rod inserted into the expansion slot. A spring is arranged between the outer surface of the expansion rod and the inner cavity wall of the expansion slot. The end of the expansion rod is arranged in a circular arc structure. When the pair of expansion rods move to the opening of the limiting pipe with an inclined structure, the pair of tinning knives can be moved relative to each other through the limiting pipe, making it easy to remove the tinned wire.

[0005] However, when tinning the copper-clad steel wire, the tin liquid wire drawing will first form a solidified state after tinning is completed.

DETAILED DESCRIPTION

[0033] The present application will be further described in detail as follows:

[0034] As shown in Figs. 1-7, the present application provides a tinning device for copper-clad steel wire, which comprises a heater 1, an electric furnace wire 2 is installed inside the heater 1, a tinning structure is arranged on the top surface of the heater 1, a scraping structure is installed on the top of the tinning structure, a cooling structure is arranged on the right side of the tinning structure, and a winding structure is arranged on the right side of the cooling structure.

[0035] The tinning structure comprises a pressing unit and a supporting and guiding unit. The pressing unit comprises a supporting frame 106, a sliding cylinder 107 is arranged at the top of the supporting frame 106, a sliding column 108 is connected to the bottom of the sliding cylinder 107, a memory spring 109 is arranged in the sliding cylinder 107, the sliding column 108 is connected to the bottom of the sliding cylinder 107, a pressing block 110 is arranged at the bottom of the sliding column 108, an electromagnetic coil 111 is arranged at the bottom of the outer surface of the sliding cylinder 107, and a magnetic block 112 is arranged at the top of the outer surface of the sliding column 108. The supporting and guiding unit comprises a tin box 101, mounting rods 102 are fixedly arranged at the left side and the right side of the tin box 101, a limiting plate 103 is arranged at the top of the mounting rods 102, rotating grooves are arranged on the top surface of the mounting rods 102, rotating shafts 104 are arranged in the rotating grooves, and guiding wheels 105 are fixedly arranged on the outer surface of the rotating shafts 104. The bottom of the supporting frame 106 is fixedly connected to the front middle part and the back middle part of the tin box 101, a groove is arranged in the middle part of the bottom of the pressing block 110, and the bottom of the limiting plate 103 is connected to the top of the mounting rods 102 by a fixing bolt.

[0036] The scraping structure comprises a connecting shaft 201, an adjusting frame 202 is connected to the outer surface of the connecting shaft 201, a threaded cylinder 203 is fixedly arranged at the top middle part of the adjusting frame 202, and a scraping ring 204 is threadedly connected to the inside of the threaded cylinder 203. The connecting shafts 201 are fixedly connected to the front and back bottom ends of the supporting frame 106 at the side close to each other, and the outer surface of the connecting shaft 201 is rotatably connected to the inner wall of the rotating hole arranged at the front and back bottom ends of the adjusting frame 202.

[0037] Through the arrangement of the tinning structure, the electromagnetic coil 111 pushes the magnetic block 112 to make the sliding column 108 slide in the sliding cylinder 107, drives the pressing block 110 to descend, presses the copper-clad steel wire into the tin box 101, and makes the copper-clad steel wire immerse below the tin liquid surface to better tin the copper-clad steel wire. Since the pressing block 110 drives the copper-clad steel wire to immerse below the tin liquid surface, the heat of the tin liquid can be conducted through the sliding column 108 and the sliding cylinder 107 to heat the memory spring 109, so that the copper-clad steel wire can always be below the tin liquid surface, and the tinning effect is better.

[0038] By the setting of the scraping structure, the excess tin liquid on the surface of the copper-clad steel wire after tinning can be scraped by the scraping ring 204, preventing the phenomenon of tin liquid drawing, which helps to ensure the quality of the copper-clad steel wire. At the same time, the scraping ring 204 is connected with the threaded cylinder 203 through threads, which facilitates the replacement of the scraping ring 204 and adapts to copper-clad steel wires with various cross-sectional diameters. By the setting of the adjusting frame and the connecting shaft, when the tin liquid level changes with the tinning time, the guiding angle of the copper-clad steel wire will change accordingly. The angle of the scraping ring 204 can be adjusted by the adjusting frame 202, so that the excess tin liquid on the surface of the copper-clad steel wire can be better scraped. At the same time, the scraping ring 204 can always be on the top surface inside the tin box 101, and the scraped tin liquid can flow into the tin box 101, without causing waste of raw materials.

[0039] The cooling structure comprises a support column 301, an arc-shaped plate 302 fixedly installed at the top of the support column 301, a bearing 303 fixedly connected to the top surface of the arc-shaped plate 302, a rotating cylinder 304 connected inside the bearing 303, a stress spring 305 fixedly installed inside the rotating cylinder 304, a spoiler 306 fixedly connected to the end of the stress spring 305 away from the inner wall of the rotating cylinder 304, a driven wheel 307 fixedly installed on the outer surface of the rotating cylinder 304, a belt 308 in transmission connection with the outer surface of the driven wheel 307, a driving wheel 309 in transmission connection with the end of the belt 308 away from the driven wheel 307, a driving shaft 310 fixedly installed at the left middle of the driving wheel 309, a rotating motor 311 connected to the left end of the driving shaft 310, a fixing block 312 detachably connected to the bottom surface of the rotating motor 311, and blades 313 installed inside the rotating cylinder 304. The size of the driving wheel 309 is smaller than that of the driven wheel 307. The bearing 303, the arc-shaped plate 302 and the support column 301 are provided in two groups and are installed at the left and right ends of the rotating cylinder 304. An installation through groove is formed in the blade 313, and an air bag 314 is installed in the installation through groove. A circular hole is formed in the side of the blade 313 away from the inner wall of the rotating cylinder 304, and a one-way valve 315 is installed in the circular hole.

[0040] The winding structure comprises a fixed column 401, an installation plate 402 fixedly installed on the front surface of the fixed column 401, an asynchronous motor 403 detachably installed on the top surface of the installation plate 402, a shaft one 404 connected to the output end of the asynchronous motor 403, a driving gear 405 fixedly installed on the outer surface of the shaft one 404, a driven gear 406 in meshing connection with the outer surface of the driving gear 405, a shaft two 407 fixedly installed on the inner surface of the driven gear 406, and a winding wheel 408 fixedly installed on the outer surface of the shaft two 407. A connecting groove is formed in the top surface of the fixed column 401, and the bottom of the inner wall of the connecting groove is in rotational connection with the front and back ends of the outer surface of the shaft two 407. Threaded holes are formed in the outer surface of the shaft two 407 near the front and back ends of the winding wheel 408, and bolts are in threaded connection with the temples of the threaded holes.

[0041] Through the setting of the cooling structure, the asynchronous motor 403 drives the belt 308 and the driven wheel 307 to rotate, which can make the rotating cylinder 304 rotate. Through the blades 313 installed at the left and right ends inside the rotating cylinder 304, the air flow can be sucked into the rotating cylinder 304 through the blades 313 when the rotating cylinder 304 rotates. The stress spring 305 drives the spoiler 306 to vibrate through the centrifugal force of rotation, which can change the air flow inside the rotating cylinder 304 and cool the tinned copper-clad steel wire.

[0042] The working principle of the tinning device for the copper-clad steel wire will be described below.

[0043] As shown in FIGS. 1-8, the tin box 101 can be continuously and constantly heated by the heater 1, so that the tin inside the tin box 101 can always remain in a liquid state. The copper-clad steel wire is conveyed through the grooves on the outer surfaces of the two guide wheels 105. At this time, the electromagnetic coil 111 is energized to generate a magnetic pole opposite to the magnetic block 112, which pushes the magnetic block 112 to make the slide column 108 slide downward in the slide cylinder 107, driving the pressing block 110 to press the copper-clad steel wire to descend below the tin liquid level in the tin box 101. At this time, the copper-clad steel wire can be tinned. After the pressing block 110 contacts the tin liquid, the high temperature of the tin liquid can be conducted to the inside of the slide column 108 and the slide cylinder 107 through the pressing block 110, thereby heating the memory spring 109 and gradually expanding it to push the slide column 108 to continuously slide downward, thereby ensuring that the copper-clad steel wire continuously descends below the tin liquid level, effectively ensuring better tinning effect. When the copper-clad steel wire passes through the pressing block 110 and passes through the inside of the scraping ring 204, the scraping ring 204 can be used to scrape the excess tin liquid on the outer surface of the copper-clad steel wire to prevent the phenomenon of tin liquid drawing from occurring, thereby affecting the quality of the copper-clad steel wire. During this process, the tin liquid may gradually decrease and the liquid level may decrease due to the continuous tinning work. Therefore, the height and angle of the scraping ring 204 can be adjusted by the rotating connection of the adjusting frame 202 and the connecting shaft 201 to better scrape the tin liquid on the surface of the copper-clad steel wire.

[0044] After the excess tin liquid is scraped off, the copper-clad steel wire enters the inside of the rotating cylinder 304, and the driving shaft 310 and the driving wheel 309 are driven to rotate by starting the rotating motor 311, so that the driven wheel 307 is driven to rotate by the belt 308, and the driven wheel 307 drives the rotating cylinder 304 to rotate when it rotates. When the rotating cylinder 304 rotates, the airflow can be introduced into the inside of the rotating cylinder 304 through the blades 313 installed at the left and right ends of the rotating cylinder 304, and at the same time, the stress spring 304 and the spoiler 306 will swing within a certain amplitude when the rotating cylinder 305 rotates, so that the airflow in the inside of the rotating cylinder 304 changes. The heat of the tin liquid on the surface of the copper-clad steel wire passing through the inside of the rotating cylinder 304 is effectively dissipated by the airflow, so that the tin liquid on the surface of the copper-clad steel wire can be better solidified. At the same time, the air bag 314 installed in the blade 313 will expand in the process of rotating the rotating cylinder 304, and after expanding to a certain extent, the one-way valve 315 is extruded, and when the one-way valve 315 is extruded, the internal gas can be sprayed out. Because the flow rate of the airflow entering the air bag 314 inside the blade 313 during rotation is different, the expansion speed of the air bag 314 inside the plurality of blades 313 is also different, and the rate of air discharged from the one-way valve 315 is also different, so that the airflow speed in the inside of the rotating cylinder 305 changes, the heat dissipation of the tin liquid on the surface of the copper-clad steel wire is accelerated, and the cooling effect is improved. Then the shaft one 404 is driven to rotate by starting the asynchronous motor 403, thereby driving the driving gear 405 to rotate, and the shaft two 407 is driven to rotate by the meshing connection of the driving gear 405 and the driven gear 406. The winding wheel 408 is driven to rotate when the shaft two 407 rotates, so that the copper-clad steel wire after tin plating can be wound, and at the same time, the bolts on the surface of the shaft two 407 can be used to realize the quick installation and disassembly of the winding wheel 408.

[0045] The above is a detailed description of the present application in general, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, the modifications or improvements without departing from the spirit of the present application are within the scope of the present application.
