Description

Technical Field

[0001] The invention belongs to the technical field of copper-clad round steel wire welding, and in particular relates to a copper-clad round steel wire welding device. Background Art

[0002] Copper-clad steel round wire is an important material for grounding systems and is widely used in power, communications, construction, lightning protection and other fields. Copper-clad steel round wire is a composite material formed by coating a uniform copper layer on the surface of a steel substrate using electroplating or continuous casting. This structure combines the good conductivity of copper with the high strength of steel, allowing it to maintain good performance in a variety of environments.

[0003] Before welding, the welding end face of the copper-clad round steel wire needs to be polished to make it smooth, thereby improving the welding strength of the copper-clad round steel wire. Since the copper layer on the outside of the copper-clad round steel wire is related to the electrical conductivity of the copper-clad round steel wire, it is necessary to avoid polishing the copper layer as much as possible. When polishing the welding end face of the copper-clad round steel wire, high temperature will be generated locally on the polishing surface. Since the thermal expansion coefficient of the copper layer is much larger than that of the steel core, metal powder is easily adhered to the copper layer and the polishing sheet near the polishing part during continuous polishing. After the copper-clad round steel wire cools down, the metal powder will adhere to the copper layer on the copper-clad round steel wire, making it difficult to clean the metal powder and affecting the welding of the copper-clad round steel wire. Summary of the invention

[0004] The purpose of the present invention is to provide a copper-clad steel round wire welding device to solve the technical problems in the prior art in view of the shortcomings of the prior art.

[0005] The objective of the present invention can be achieved through the following technical scheme: a copper-clad steel round wire welding device, which includes a workbench and a correction track installed thereon, a welding table is installed in the middle of the correction track, a driving correction roller and an adjusting correction roller are respectively installed on the correction track, a fixing frame and a grinding cylinder are respectively installed on the welding table, the output end of the grinding cylinder is connected to the grinding assembly, the grinding assembly includes a scissors-type member and two grinding plates connected to the scissors-type member, the scissors-type member is connected to the output end of the grinding cylinder, ventilation micropores are opened on the grinding plates, the two grinding plates are connected by an airbag cavity, and the airbag cavity is connected to the ventilation micropores on the grinding plates, the scissors-type member squeezes the airbag cavity, and the airbag cavity is connected to the air pump.

[0006] As a further optimization or improvement of the present solution, the welding platform includes an adjustment frame and a slide groove, and the scissors-type member is slidably matched with the slide groove.

[0007] As a further optimization or improvement of the present solution, the grinding assembly further comprises a pressure rod, which is mounted on the motion joint of the scissors-type member and squeezes the airbag cavity.

[0008] As a further optimization or improvement of the present solution, an alignment assembly is installed on the workbench, and the alignment assembly includes a sliding plate and a sliding sleeve. The sliding sleeve is slidably connected to the output end of the polishing cylinder. A transverse groove is provided 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 the copper-clad steel round wire.

[0009] As a further optimization or improvement of the present solution, the alignment assembly further includes a lower fixing sleeve and a locking cylinder, the locking cylinder is mounted 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 the present solution, the grinding assembly also includes a push plate, which is connected to the input end of the grinding cylinder, abuts the sliding sleeve, and is connected to the scissors-fork part through a push rod. The scissors-fork parts are slidingly connected through a sliding rod and a sliding tube, a ratchet gear is installed on the sliding tube, a rack is installed on the sliding rod, and the ratchet gear is meshed with the rack.

[0011] As a further optimization or improvement of the present solution, the welding table further includes an adjusting frame, the slide groove is opened in the adjusting frame, and the grinding plate is located in the adjusting frame for transverse adjustment.

[0012] Beneficial effects of the present invention:

[0013] (1) The present invention provides ventilation micropores on the polishing plate and slowly fills cold air into the airbag cavity through an air pump to reduce the local temperature of the polishing surface and prevent the copper layer from being overheated and adhering to metal powder;

[0014] During the grinding process, in order to prevent metal powder from clogging the ventilation micropores and causing poor ventilation, the present invention adjusts the distance between the grinding plates by pressing the scissor-fork pieces, so that the grinding plates are always in contact with the grinding surfaces during the working process. At the same time, the airbag cavity is squeezed by pressing the scissor-fork pieces, and the gas inside the airbag cavity is discharged through the micropores of the grinding plate, thereby achieving the effect of clearing the micropores. When the gas inside the airbag cavity passes through the unblocked micropores, the gas inside the airbag cavity can pass through the micropores to clean up the metal powder that has fallen on 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 separated from the slide groove. In the process of the push plate moving up, the push plate will drive the sliding sleeve to move up synchronously. The upward movement of the sliding sleeve 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 contact, the two copper-clad steel round wires collide, and the metal powder adhering to the copper layer of the copper-clad steel round wire is shaken off. At the same time, the welding ends of the two copper-clad steel round wires are automatically aligned, which is convenient for welding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present 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 creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 6A copper-clad steel round wire welding device comprises a workbench 1 and a correction track 2 installed thereon, a welding table 8 is installed in the middle of the correction track 2, a driving correction roller 3 and an adjusting correction roller 4 are respectively installed on the correction 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 the grinding component 9, the grinding component 9 comprises a scissors-fork piece 904 and two grinding plates 902 connected to the scissors-fork piece 904, the scissors-fork piece 904 is connected to the output end of the grinding cylinder 6, ventilation micropores are opened on the grinding plates 902, the two grinding plates 902 are connected by an airbag cavity 907, and the airbag cavity 907 is connected to the ventilation micropores on the grinding plates 902, the scissors-fork piece 904 squeezes the airbag cavity 907, and the airbag cavity 907 is connected to the air pump.

[0029] It should be noted that the airbag cavity 907 is connected to an air pump, and the air pump continuously and slowly fills cold air into the airbag cavity 907. The temperature of the cold air is maintained in a specified range. In the range, the cold air slowly shrinks the metal surface, thereby effectively eliminating internal stress and cooling the copper-clad steel round wire. It should be noted that the air pump cannot quickly fill the airbag cavity 907 with cold air. Filling the cold air too quickly will cause the metal surface to shrink rapidly, which may easily cause cracks on the metal surface.

[0030] When in use, the driving correction roller 3 is adjusted to make the copper-clad steel round wire corrected by the driving correction roller 3 and the adjusting correction roller 4, and then the corrected copper-clad steel round wire is clamped by the lower fixing sleeve 706 and the upper fixing sleeve 705, and the grinding cylinder 6 is started. The grinding cylinder 6 drives the scissor fork 904 and the grinding plate 902 to move downward synchronously through the push plate 901, and the scissor fork 904 slides down along the slide groove 802. When the scissor fork 904 moves to the bottom of the slide groove 802, the grinding cylinder 6 presses the push plate 901. The scissors fork piece 904 drives the grinding plate 902 to move relatively, and the grinding plate 902 gradually fits the end of the copper-clad steel round wire. At this time, the ratchet gear 910 locks the position of the grinding plate 902, and then drives the grinding plate 902 to grind the end face of the copper-clad steel round wire through the grinding cylinder 6. During this process, every time the scissors fork piece 904 passes through the bottom of the slide groove 802, the grinding cylinder 6 will press the scissors fork piece 904, so that the grinding plate 902 always fits the end face of the copper-clad steel round wire, thereby improving the grinding efficiency.

[0031] It should be noted that the present invention opens ventilation micropores on the polishing plate 902 and slowly fills cold air into the airbag cavity 907 through an air pump to reduce the local temperature of the polishing surface and prevent the copper layer from being overheated and adhering to metal powder.

[0032] During the grinding process, the ventilation micropores are very likely to be blocked by metal powder, resulting in poor ventilation. Therefore, the present invention adjusts the distance between the grinding plates 902 by pressing the scissor-fork piece 904, so that the grinding plates 902 always fit the grinding surface during the working process. At the same time, the airbag cavity 907 is squeezed by pressing the scissor-fork piece 904, and the internal gas of the airbag cavity 907 is discharged through the micropores of the grinding plate 902, thereby achieving the effect of clearing the micropores. When the internal gas of the airbag cavity 907 passes through the unblocked micropores, the internal gas of the airbag cavity 907 can pass through the micropores to clean the metal powder dropped on the copper layer.

[0033] See also Figure 4 The welding platform 8 includes an adjustment frame 801 and a slide groove 802 , and the scissor member 904 is slidably matched with the slide groove 802 .

[0034] Specifically, the welding table 8 further includes an adjusting frame 801 , a slide groove 802 is opened in the adjusting frame 801 , and a grinding plate 902 is located in the adjusting 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 the grinding is completed, the copper-clad steel round wire can be directly welded by the arc welding gun 803.

[0036] See also Figure 5 The grinding assembly 9 also includes a pressure rod 906 , which is installed on the motion joint of the scissor member 904 , and the pressure rod 906 squeezes the airbag cavity 907 .

[0037] See also Figure 3 and Fig. 9 An alignment component 7 is installed on the workbench 1, and 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 polishing cylinder 6. A transverse groove 704 is provided on the sliding plate 703, and 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, and the upper fixed sleeve 705 is connected to the copper-clad steel round wire.

[0038] Specifically, the alignment assembly 7 further 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, and the corrected copper-clad steel round wire is placed between the upper fixing sleeve 705 and the lower fixing sleeve 706, and the locking cylinder 707 is started to drive the lower fixing sleeve 706 to clamp the copper-clad steel round wire.

[0040] When in use, after the grinding plate 902 finishes grinding the copper-clad round steel wire, the copper layer on the copper-clad round steel wire is in a high temperature state. Figure 3The polishing cylinder 6 drives the push plate 901 and the polishing plate 902 to move upward, so that the scissor fork piece 904 on the polishing plate 902 is separated from the slide groove 802. In the process of the push plate 901 moving upward, the push plate 901 will drive the sliding sleeve 701 to move upward synchronously. The upward movement of the sliding sleeve 701 drives the upper fixed sleeve 705 and the copper-clad steel round wire thereon 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 contact, the two copper-clad steel round wires collide, and the metal powder remaining on the copper layer of the copper-clad steel round wire is shaken off. At the same time, the welding ends of the two copper-clad steel round wires are aligned to facilitate welding.

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

[0042] It should be noted that the pawl on the ratchet gear 910 can be electrically adjusted. When the grinding is completed, the pawl automatically disengages from the ratchet gear 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 scissors fork 904 is folded, and the two grinding plates 902 are retracted.

[0043] The implementation principle of the present invention is:

[0044] When in use, the driving correction roller 3 is adjusted to make the copper-clad steel round wire corrected by the driving correction roller 3 and the adjusting correction roller 4, and then the corrected copper-clad steel round wire is clamped by the lower fixing sleeve 706 and the upper fixing sleeve 705, and the grinding cylinder 6 is started. The grinding cylinder 6 drives the scissor fork 904 and the grinding plate 902 to move downward synchronously through the push plate 901, and the scissor fork 904 slides down along the slide groove 802. When the scissor fork 904 moves to the bottom of the slide groove 802, the grinding cylinder 6 presses the push plate 901. The scissors fork piece 904 drives the grinding plate 902 to move relatively, and the grinding plate 902 gradually fits the end of the copper-clad steel round wire. At this time, the ratchet gear 910 locks the position of the grinding plate 902, and then drives the grinding plate 902 to grind the end face of the copper-clad steel round wire through the grinding cylinder 6. During this process, every time the scissors fork piece 904 passes through the bottom of the slide groove 802, the grinding cylinder 6 will press the scissors fork piece 904, so that the grinding plate 902 always fits the end face of the copper-clad steel round wire, thereby improving the grinding efficiency.

[0045] The present invention opens ventilation micropores on the polishing plate 902 and slowly fills cold air into the airbag cavity 907 through an air pump, thereby reducing the local temperature of the polishing surface and preventing the copper layer from being overheated and adhering to metal powder. During the polishing process, the ventilation micropores are easily blocked by metal powder, resulting in poor ventilation. Therefore, the present invention adjusts the distance between the polishing plates 902 by pressing the scissor-fork member 904, so that the polishing plates 902 always fit the polishing surface during operation. At the same time, the airbag cavity 907 is squeezed by pressing the scissor-fork member 904, and the gas inside the airbag cavity 907 is discharged through the micropores of the polishing plate 902, thereby clearing the micropores. When the gas inside the airbag cavity 907 passes through the unblocked micropores, the gas inside the airbag cavity 907 can pass through the micropores to clean up part of the metal powder that has fallen on the copper layer.

[0046] When the grinding plate 902 finishes grinding the copper-clad round steel wire, the copper layer on the copper-clad round steel wire is in a high temperature state. Figure 3 , the polishing cylinder 6 drives the push plate 901 and the polishing plate 902 to move upward, so that the scissor fork piece 904 on the polishing plate 902 is separated from the slide groove 802. In the process of the push plate 901 moving upward, the push plate 901 will drive the sliding sleeve 701 to move upward synchronously. The upward movement of the sliding sleeve 701 drives the upper fixed sleeve 705 and the copper-clad steel round wire thereon 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 contact, the two copper-clad steel round wires collide, and the metal powder remaining on the copper layer of the copper-clad steel round wire is shaken off. At the same time, the welding ends of the two copper-clad steel round wires are aligned to facilitate welding. At this time, the polishing cylinder 6 drives the polishing plate 902 to separate from the slide groove 802, and the copper-clad steel round wire can be directly welded by the arc welding gun 803.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
