Description

Technical Field

[0001] This invention belongs to the field of copper-clad steel round wire welding technology, and specifically relates to a copper-clad steel round wire welding device. Background Technology

[0002] Copper-clad steel round wire is an important material used in grounding systems, widely applied in power, communications, construction, and lightning protection. It is a composite material formed by electroplating or continuous casting to coat a steel substrate with a uniformly thick layer of copper. This structure combines the excellent conductivity of copper with the high strength of steel, allowing it to maintain good performance in various environments.

[0003] Before welding copper-clad steel (CCS) round wire, the welding end face needs to be ground smooth to improve the welding strength. Since the copper layer on the outside of the CCS round wire is related to its conductivity, grinding of the copper layer should be avoided as much as possible. When grinding the welding end face of the CCS round wire, high temperatures are generated locally. Because the coefficient of thermal expansion of the copper layer is much greater than that of the steel core, metal powder easily adheres to the copper layer and grinding disc near the grinding area during continuous grinding. After the CCS round wire cools, the metal powder will solidify on the copper layer, making it difficult to clean and affecting the welding process. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a copper-clad steel round wire welding device to solve the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solution: a copper-clad steel round wire welding device, comprising a worktable and a straightening track mounted thereon, a welding table installed in the middle of the straightening track, a drive straightening roller and an adjustment straightening roller respectively installed on the straightening track, a fixed frame and a grinding cylinder respectively installed on the welding table, the output end of the grinding cylinder connected to a grinding assembly, the grinding assembly comprising a scissor fork and two grinding plates connected to the scissor fork, the scissor fork being connected to the output end of the grinding cylinder, ventilation micro-holes being provided on each grinding plate, the two grinding plates being connected through an air bladder cavity, and the air bladder cavity communicating with the ventilation micro-holes on the grinding plate, the scissor fork squeezing the air bladder cavity, the air bladder cavity being connected to an air pump.

[0006] As a further optimization or improvement of this solution, the welding table includes an adjustment frame and a slide groove, with the scissor fork slidingly engaged with the slide groove.

[0007] As a further optimization or improvement of this solution, the grinding assembly also includes a pressure rod, which is installed on the moving section of the scissor lift and compresses the airbag cavity.

[0008] As a further optimization or improvement of this solution, an alignment component is installed on the worktable. The alignment component includes a sliding plate and a sliding sleeve. The sliding sleeve is slidably connected to the output end of the grinding cylinder. A transverse groove is opened on the sliding plate, and an upper fixed sleeve is slidably installed in the transverse groove. The sliding sleeve and the upper fixed sleeve are connected by a rotating rod, and the upper fixed sleeve is connected to a copper-clad steel round wire.

[0009] As a further optimization or improvement of this solution, the alignment assembly also includes a lower fixing sleeve and a locking cylinder. The locking cylinder is installed on the upper fixing sleeve, and the output end of the locking cylinder is connected to the lower fixing sleeve.

[0010] As a further optimization or improvement of this solution, the grinding assembly also includes a push plate, which is connected to the input end of the grinding cylinder. The push plate abuts against the sliding sleeve, and the push plate is connected to the scissor fork via a push rod. The scissor forks are slidably connected to each other via a sliding rod and a sliding tube. A ratchet is installed on the sliding tube, and a rack is installed on the sliding rod. The ratchet meshes with the rack.

[0011] As a further optimization or improvement of this solution, the welding table also includes an adjustment frame, a sliding groove is opened inside the adjustment frame, and a grinding plate is adjusted laterally within the adjustment frame.

[0012] The beneficial effects of this invention are:

[0013] (1) The present invention reduces the local temperature of the polishing surface by opening ventilation micro-holes on the polishing plate and slowly filling the airbag cavity with cold air through an air pump, thereby avoiding the copper layer temperature from being too high and adhering to metal powder.

[0014] During the polishing process, to prevent metal powder from clogging the ventilation micropores and causing poor ventilation, this invention adjusts the distance between the polishing plates by pressing the scissor fork, ensuring that the polishing plates always fit the polishing surface during operation. At the same time, by pressing the scissor fork, the air bladder cavity is squeezed, and the gas inside the air bladder cavity is discharged through the micropores of the polishing plates, thus clearing the micropores. When the gas inside the air bladder cavity passes through the unblocked micropores, it can clean the metal powder that has fallen onto the copper layer.

[0015] (2) After the grinding plate finishes grinding the copper-clad steel round wire, the grinding cylinder drives the push plate and the grinding plate to move up, so that the scissor fork on the grinding plate is disengaged from the slide groove. During the process of the push plate moving up, the push plate will drive the slide sleeve to move up synchronously. The slide sleeve moves up and drives the upper fixed sleeve and the copper-clad steel round wire on it to move along the transverse groove, so that the two copper-clad steel round wires move relative to each other. When the two copper-clad steel round wires come into contact, they collide and shake off the metal powder adhering to the copper layer of the copper-clad steel round wire. At the same time, the welding ends of the two copper-clad steel round wires are automatically aligned, which facilitates welding. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] See Figures 1-6A copper-clad steel round wire welding device includes a workbench 1 and a straightening track 2 mounted on it. A welding table 8 is installed in the middle of the straightening track 2. A drive straightening roller 3 and an adjusting straightening roller 4 are respectively installed on the straightening track 2. A fixing frame 5 and a grinding cylinder 6 are respectively installed on the welding table 8. The output end of the grinding cylinder 6 is connected to a grinding assembly 9. The grinding assembly 9 includes a scissor fork 904 and two grinding plates 902 connected to the scissor fork 904. The scissor fork 904 is connected to the output end of the grinding cylinder 6. Each grinding plate 902 has ventilation micro-holes. The two grinding plates 902 are connected by an air bladder cavity 907, and the air bladder cavity 907 communicates with the ventilation micro-holes on the grinding plates 902. The scissor fork 904 squeezes the air bladder cavity 907, and the air bladder cavity 907 is connected to an air pump.

[0029] It should be noted that the air chamber 907 is connected to an air pump. The air pump continuously and slowly fills the air chamber 907 with cold air, maintaining the temperature within a specified range. Within this range, the cold air slowly contracts the metal surface, effectively eliminating internal stress and simultaneously cooling the copper-clad steel round wire. It is important to note that the air pump should not rapidly fill the air chamber 907 with cold air. Rapid filling will cause the metal surface to contract rapidly, potentially leading to cracks in the metal surface.

[0030] In use, adjust the drive straightening roller 3 so that the copper-clad steel round wire passes through the drive straightening roller 3 and the adjusting straightening roller 4 for straightening. Then, the straightened copper-clad steel round wire is clamped by the lower fixed sleeve 706 and the upper fixed sleeve 705. Start the grinding cylinder 6. The grinding cylinder 6 drives the scissor lift 904 and the grinding plate 902 to move down synchronously through the push plate 901. At the same time, the scissor lift 904 slides down along the slide groove 802. When the scissor lift 904 moves to the bottom of the slide groove 802, the grinding cylinder 6 presses down through the push plate 901. The scissor lift 904 causes the grinding plate 902 to move relative to it, gradually bringing the grinding plate 902 into contact with the end of the copper-clad steel round wire. At this time, the ratchet gear 910 locks the position of the grinding plate 902. Then, the grinding cylinder 6 drives the grinding plate 902 to grind the end face of the copper-clad steel round wire. During this process, the grinding cylinder 6 presses the scissor lift 904 as it passes the bottom of the slide groove 802, so that the grinding plate 902 always keeps in contact with the end face of the copper-clad steel round wire, improving the grinding efficiency.

[0031] It should be noted that the present invention reduces the local temperature of the polished surface by opening ventilation micro-holes on the polishing plate 902 and slowly filling the air chamber 907 with cold air through an air pump, thereby preventing the copper layer from getting too hot and causing metal powder to stick.

[0032] During the polishing process, the ventilation micropores are easily clogged by metal powder, resulting in poor ventilation. Therefore, this invention adjusts the distance between the polishing plates 902 by pressing the scissor fork 904, so that the polishing plates 902 always fit the polishing surface during operation. At the same time, by pressing the scissor fork 904, the air bladder 907 is squeezed, and the gas inside the air bladder 907 is discharged through the micropores of the polishing plates 902, thereby clearing the micropores. When the gas inside the air bladder 907 passes through the unblocked micropores, it can clean the metal powder that has fallen onto the copper layer.

[0033] See Figure 4 The welding table 8 includes an adjustment frame 801 and a slide groove 802, and the scissor fork 904 is slidably engaged with the slide groove 802.

[0034] Specifically, the welding table 8 also includes an adjustment frame 801, a slide 802 is opened inside the adjustment frame 801, and a grinding plate 902 is located in the adjustment frame 801 for horizontal adjustment.

[0035] It should be noted that an arc welding gun 803 is installed on one side of the adjustment frame 801. After grinding is completed, the copper-clad steel round wire can be welded directly through the arc welding gun 803.

[0036] See Figure 5 The grinding assembly 9 also includes a pressure rod 906, which is installed on the moving section of the scissor lift 904 and compresses the air chamber 907.

[0037] See Figure 3 and Figure 9 The alignment component 7 is installed on the worktable 1. The alignment component 7 includes a sliding plate 703 and a sliding sleeve 701. The sliding sleeve 701 is slidably connected to the output end of the grinding cylinder 6. A transverse groove 704 is opened on the sliding plate 703. An upper fixed sleeve 705 is slidably installed in the transverse groove 704. The sliding sleeve 701 and the upper fixed sleeve 705 are connected by a rotating rod 702. The upper fixed sleeve 705 is connected to a copper-clad steel round wire.

[0038] Specifically, the alignment assembly 7 also includes a lower fixing sleeve 706 and a locking cylinder 707. The locking cylinder 707 is installed on the upper fixing sleeve 705, and the output end of the locking cylinder 707 is connected to the lower fixing sleeve 706.

[0039] It should be noted that a locking cylinder 707 is installed on the upper fixing sleeve 705. The corrected copper-clad steel round wire is placed between the upper fixing sleeve 705 and the lower fixing sleeve 706. The locking cylinder 707 is activated, causing the lower fixing sleeve 706 to clamp the copper-clad steel round wire.

[0040] During use, after the grinding plate 902 finishes grinding the copper-clad steel round wire, the copper layer on the wire is at a high temperature. (See...) Figure 3The grinding cylinder 6 drives the push plate 901 and the grinding plate 902 to move upward, causing the scissor fork 904 on the grinding plate 902 to disengage from the slide groove 802. During the upward movement of the push plate 901, the push plate 901 will drive the slide sleeve 701 to move upward synchronously. The upward movement of the slide sleeve 701 will drive the upper fixed sleeve 705 and the copper-clad steel round wire on it to move along the transverse groove 704, so that the two copper-clad steel round wires move relative to each other. When the two copper-clad steel round wires come into contact, they will collide, shaking off the metal powder remaining on the copper layer of the copper-clad steel round wires. At the same time, the welding ends of the two copper-clad steel round wires are aligned, which facilitates welding.

[0041] See Figures 7-8 The grinding assembly 9 also includes a push plate 901, which is connected to the input end of the grinding cylinder 6. The push plate 901 abuts against the sliding sleeve 701. The push plate 901 is connected to the scissor fork 904 via the push rod 903. The scissor forks 904 are slidably connected to each other via the sliding rod 908 and the sliding tube 905. A ratchet 910 is installed on the sliding tube 905, and a rack 909 is installed on the sliding rod 908. The ratchet 910 meshes with the rack 909.

[0042] It should be noted that the pawl on the ratchet 910 is electrically adjustable. When the grinding is finished, the pawl automatically disengages from the ratchet 910. At this time, when the grinding cylinder 6 drives the push plate 901 to move upward, the slide rod 908 slides along the sliding tube 905, the scissor fork 904 folds, and the two grinding plates 902 retract.

[0043] The implementation principle of this invention is as follows:

[0044] In use, adjust the drive straightening roller 3 so that the copper-clad steel round wire passes through the drive straightening roller 3 and the adjusting straightening roller 4 for straightening. Then, the straightened copper-clad steel round wire is clamped by the lower fixed sleeve 706 and the upper fixed sleeve 705. Start the grinding cylinder 6. The grinding cylinder 6 drives the scissor lift 904 and the grinding plate 902 to move down synchronously through the push plate 901. At the same time, the scissor lift 904 slides down along the slide groove 802. When the scissor lift 904 moves to the bottom of the slide groove 802, the grinding cylinder 6 presses down through the push plate 901. The scissor lift 904 causes the grinding plate 902 to move relative to it, gradually bringing the grinding plate 902 into contact with the end of the copper-clad steel round wire. At this time, the ratchet gear 910 locks the position of the grinding plate 902. Then, the grinding cylinder 6 drives the grinding plate 902 to grind the end face of the copper-clad steel round wire. During this process, the grinding cylinder 6 presses the scissor lift 904 as it passes the bottom of the slide groove 802, so that the grinding plate 902 always keeps in contact with the end face of the copper-clad steel round wire, improving the grinding efficiency.

[0045] This invention reduces the local temperature of the polishing surface by creating ventilation micro-holes in the polishing plate 902 and slowly filling the air chamber 907 with cold air using an air pump, thus preventing the copper layer from overheating and adhering metal powder. During the polishing process, the ventilation micro-holes are easily blocked by metal powder, leading to poor ventilation. Therefore, this invention adjusts the spacing between the polishing plates 902 by pressing the scissor fork 904, ensuring that the polishing plates 902 always fit the polishing surface during operation. At the same time, pressing the scissor fork 904 squeezes the air chamber 907, and the gas inside the air chamber 907 is discharged through the micro-holes of the polishing plate 902, thus clearing the micro-holes. When the gas inside the air chamber 907 passes through unblocked micro-holes, it can clean some of the metal powder that has fallen onto the copper layer.

[0046] After the grinding plate 902 finishes grinding the copper-clad steel round wire, the copper layer on the wire is at a high temperature. (See below) Figure 3 The grinding cylinder 6 drives the push plate 901 and the grinding plate 902 to move upward, causing the scissor fork 904 on the grinding plate 902 to disengage from the slide groove 802. During the upward movement of the push plate 901, the push plate 901 will drive the slide sleeve 701 to move upward synchronously. The upward movement of the slide sleeve 701 will drive the upper fixed sleeve 705 and the copper-clad steel round wire on it to move along the transverse groove 704, causing the two copper-clad steel round wires to move relative to each other. When the two copper-clad steel round wires come into contact, they will collide, shaking off the metal powder remaining on the copper layer of the copper-clad steel round wires. At the same time, the welding ends of the two copper-clad steel round wires will be aligned to facilitate welding. At this time, the grinding cylinder 6 drives the grinding plate 902 to disengage from the slide groove 802, and the copper-clad steel round wires can be directly welded by the arc welding gun 803.
