Description

Technical Field

[0001] The present invention relates to the technical field of copper-clad steel wire manufacturing, and more particularly to a multi-station tinning device applied to the copper-clad steel wire manufacturing process. Background Art

[0002] Copper-clad steel wire is a composite wire with a steel wire core and an outer copper layer. Combining the electrical conductivity of copper with the mechanical strength of steel, it is achieved through high-temperature welding, electroplating or hot-dip plating to achieve a metallurgical bond between copper and steel. The multi-station tinning process for copper-clad steel wire is an efficient production technology that achieves a metallurgical bond between the copper layer and the steel core by treating the wire surface in stages, and then covers the outer layer with a tin layer.

[0003] After tinning, copper-clad steel wire can be cooled by air or water cooling. When water cooling is used for cleaning, tin slag falling off is a common phenomenon. During the tinning process, when the high-temperature tin liquid comes into contact with the copper-clad steel wire, tin slag is generated due to temperature fluctuations, metal oxidation and physical impact. These slag include tin oxides and incompletely attached free tin particles. When water cooling is used, the tin slag suspended in the cooling pool and falling above the limit wheel poses a risk of scratching the copper-clad steel wire. A solution is now provided for this problem. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figures 1-8 As shown, in this embodiment, a multi-station tinning device for copper-clad steel wire manufacturing process includes a tinning pool 1 and a cooling pool 2 arranged on the output side thereof. A support frame 3 is provided on the top of the cooling pool 2. A plurality of sets of cooling long plates 81 arranged in parallel with each other for cooling the copper-clad steel wire are fixedly provided inside the cooling pool 2. A semicircular groove 82 is provided on the top of the cooling long plate 81. A plurality of sets of arc-shaped grooves 83 arranged in parallel with each other are provided on the inner wall of the semicircular groove 82. A cooling assembly 9 for cooling the copper-clad steel wire is provided above the plurality of cooling long plates 81. The cooling assembly 9 includes a liftable arc-shaped plate 96 arranged inside the arc-shaped groove 83, a retaining plate 97 is fixedly arranged above the arc-shaped plate 96, and two groups of long water spray plates 95 are symmetrically arranged above the cooling long plate 81. A slide groove 99 is opened on the side wall opposite to the long water spray plate 95 and the arc-shaped plate 96. The slide groove 99 is a T-shaped groove. A T-shaped block is slidably arranged inside the slide groove 99. A pull rod 98 is rotatably provided on the top of the T-shaped block. The other end of the pull rod 98 is rotatably connected to the arc-shaped plate 96. When the curved plate 96 moves upward, it drives the pull rod 98 to pull the outer side of the long water spray plate 95 outward. At this time, the bottom of the curved plate 96 drives the copper-clad steel wire upward to prevent the bottom of the copper-clad steel wire from contacting the semicircular groove 82 of the cooling long plate 81. In addition, part of the water spraying side of the long water spray plate 95 is directed toward the inner wall of the semicircular groove 82, discharging the tin slag and impurities remaining in the semicircular groove 82 to the outside of the semicircular groove 82 and being filtered by the first filter plate 10 and the second filter plate. Limit rods 910 are fixedly provided on the inner walls of the two sets of long water spray plates 95. The ends of the two sets of limit rods 910 are rotated together to form side connecting plates 92, which are fixedly connected to the cooling pool 2. When the curved plate 96 is reset, the bottom of the long water spray plate 95 contacts the inner wall of the semicircular groove 82 again, so that the bottom of the copper-clad steel wire is immersed in the semicircular groove 82 for water cooling, thereby ensuring its water cooling effect. Through the above steps, the tin slag and impurities inside the cooling long plate 81 are regularly cleaned to prevent the tin slag from scratching the outer wall of the copper-clad steel wire, thereby improving the tin plating quality. In the above steps, the first filter plate 10 and the second filter plate can be cleaned regularly to avoid clogging of the two, ensure the continuous cooling of the cooling water, and improve the cooling efficiency of the copper-clad steel wire; Example 2: Please refer to Figures 1-8 As shown, two groups of long water spray plates 95 are connected by multiple groups of U-shaped tubes 94. The multiple groups of U-shaped tubes 94 are arranged parallel to each other. The multiple groups of U-shaped tubes 94 are connected by long water pipes 93. The multiple groups of long water pipes 93 are connected by lower water pipes 91. See also Figure 1-Figure 3 、 Figure 8 As shown, a water pump 51 is fixedly installed on the side wall of the cooling pool 2. The output end of the water pump 51 is connected to the upper water pipe 53. The output end of the upper water pipe 53 passes through the support frame 3 and is connected to the lower water pipe 91. The input end of the water pump 51 is connected to the water inlet pipe 52. The input end of the water inlet pipe 52 extends to the bottom of the cooling pool 2; the water inlet pipe 52 is located below the installation slot 1 and the installation slot 2. It should be noted that: the copper-clad steel wire after tinning through the tinning pool 1 enters the interior of the cooling pool 2, and the copper-clad steel wire passes through the semicircular groove 82 above the cooling long plate 81. At this time, the water pump 51 is controlled to work, and the water pump 51 delivers the cooling water at the bottom of the cooling pool 2 to the lower water pipe 91 through the water inlet pipe 52 and the upper water pipe 53. The cooling water is discharged into each long water pipe 93 through the lower water pipe 91, enters each U-shaped pipe 94 through the U-shaped pipe 94, and is discharged through the long water spray plate 95 to the outer wall of the copper-clad steel wire for water cooling and to wash away the tin slag above the copper-clad steel wire. See also Figure 8 As shown, the middle and lower part of the cooling pool 2 is provided with a mounting groove 1 and a mounting groove 2 from top to bottom. A first filter screen plate 10 is provided inside the mounting groove 1, and a blocking strip 11 is inserted on the side wall of the mounting groove 2. A rubber pad is provided on the contact surface between the blocking strip 11 and the mounting groove 2. It should be explained that a second filter screen can also be installed inside the second installation slot, and the first filter screen 10 and the second filter screen are used alternately, that is, after the first filter screen 10 is blocked, the second filter screen is immediately replaced, and the first filter screen 10 and the second filter screen are inserted into the cooling pool 2, which is convenient for replacement, and the blocking strip 11 serves to block the second installation slot or the first installation slot to prevent liquid leakage and improve the safety of the tinning device when in use; The clean water inside the cooling long plate 81 first overflows the semicircular groove 82 and then flows into the cooling pool 2, where it is filtered by the first filter plate 10 and the second filter plate, intercepting the tin slag and impurities in the clean water, and then flows into the bottom of the cooling pool 2; See also Figures 1-8 As shown, the two sets of curved plates 96 are symmetrically arranged relative to the midline of the cooling long plate 81, and the material of the retaining plate 97 is rubber to avoid scratching the copper-clad steel wire; See also Figure 1-Figure 3 、 Figure 8 As shown, an electric push rod 4 is provided above the cooling pool 2, and a middle lifting plate 7 is fixedly provided at the extended end of the electric push rod 4; Multiple sets of side lifting plates 6 are provided on both sides of the middle lifting plate 7, and the side lifting plates 6 are fixedly connected to the top of the arc-shaped plate 96; the extended end of the electric push rod 4 is intermittently controlled to retract, so that the middle lifting plate 7 and the side lifting plates 6 are moved upward synchronously, so that the arc-shaped plate 96 moves upward; See also Figure 1-Figure 3 、 Figure 8 As shown, the support frame 3 is arranged on the top wall in the middle of the cooling pool 2, and the center of the bottom of the support frame 3 is fixedly connected to the electric push rod 4; In the present invention, it can be seen from the combination of Example 1 and Example 2 that: by adjusting the angle of the long water spray plate 95, the height of the curved plate 96 is intermittently increased under the premise of continuously cooling the copper-clad steel wire, so that the bottom of the copper-clad steel wire is temporarily away from the cooling long plate 81, and part of the water flow cooled by the long water spray plate 95 is used to clean the tin slag remaining at the bottom of the cooling long plate 81, thereby preventing the tin slag from scratching the outer wall of the copper-clad steel wire and improving the tin plating quality. In addition, the tin slag is alternately filtered through the first filter plate 10 or the second filter plate to ensure the continuous use of cooling water, thereby jointly improving the cooling efficiency of the copper-clad steel wire.

[0028] Working principle: First, the copper-clad steel wire, after being tinned in the tinning pool 1, enters the interior of the cooling pool 2. The copper-clad steel wire passes through the semicircular groove 82 above the cooling long plate 81. At this time, the water pump 51 is controlled to work. The water pump 51 delivers the cooling water at the bottom of the cooling pool 2 to the lower water pipe 91 through the water inlet pipe 52 and the upper water pipe 53. The cooling water is then discharged into each long water pipe 93 through the lower water pipe 91, enters each U-shaped pipe 94 through the U-shaped pipe 94, and is discharged through the long water spray plate 95 to the outer wall of the copper-clad steel wire for water cooling and to clean the tin slag above the copper-clad steel wire. The clean water inside the cooling long plate 81 first overflows the semicircular groove 82 and then flows into the cooling pool 2, where it is filtered by the first filter plate 10 and the second filter plate, intercepting the tin slag and impurities in the clean water, and then flows into the bottom of the cooling pool 2; Subsequently, the extended end of the electric push rod 4 is intermittently controlled to retract, and the middle lifting plate 7 and the side lifting plate 6 are synchronously moved upward, so the curved plate 96 moves upward. When the curved plate 96 moves upward, it drives the pull rod 98 to pull the outer side of the long water spray plate 95 to move outward. At this time, the bottom of the curved plate 96 drives the copper-clad steel wire to move upward, preventing the bottom of the copper-clad steel wire from contacting the semicircular groove 82 of the cooling long plate 81, and part of the water spraying side of the long water spray plate 95 is directed toward the inner wall of the semicircular groove 82, discharging the remaining tin slag and impurities inside the semicircular groove 82 to the outside of the semicircular groove 82, and being filtered by the first filter plate 10 and the second filter plate; Then the extended end of the electric push rod 4 is controlled to reset, so that the bottom of the long water spray plate 95 contacts the inner wall of the semicircular groove 82 again, so that the bottom of the copper-clad steel wire is immersed in the semicircular groove 82 for water cooling to ensure its water cooling effect; through the above steps, the tin slag and impurities inside the cooling long plate 81 are regularly cleaned to avoid the tin slag scratching the outer wall of the copper-clad steel wire, thereby improving the tin plating quality; and in the above steps, the first filter plate 10 and the second filter plate can be cleaned regularly to avoid clogging of the two, thereby ensuring the continuous cooling use of the cooling water and improving the cooling efficiency of the copper-clad steel wire.
