Description

Technical Field

[0001] The invention relates to the technical field of copper strip welding equipment, and in particular to a continuous welding device for copper strip production. Background Art

[0002] In the actual copper strip production and manufacturing work, the widening and connection work of the copper strip is often involved, and welding is usually required for processing. Some copper strips are long and need to ensure welding continuity. Manual welding is difficult to meet the requirements. The current welding machines are widely used due to their advantages such as firm welding. The current continuous welding devices for copper strip production are subject to the seam limitations of the copper strip, which is not convenient for continuous negative pressure welding. Bubbles are prone to exist in the weld path, affecting the production quality of the copper strip. At the same time, it is not convenient to preheat and improve the welding stress. The copper strip is prone to deformation at the weld, and the flatness of the molten pool is not good after cooling. It is not convenient to trim the molten pool while it is hot. At the same time, when two copper strips are continuously welded, it is not convenient to control the tension of the two copper strips in real time. The loose copper strip is easy to cause the weld path to be dislocated, and the excessive tension conveying method will pull and damage the copper strip. Summary of the invention

[0042] The working principle of this embodiment is as follows: first, two copper belts are placed between the driven wheel 103 and the conveying wheel 102, and then pass through the upper limit plate 402, and then pass through between the driving support wheel 204 and the driving roller 302, and the conveying motor 104 is started to drive the copper belt to move at a constant speed, and the two copper belt control motors 301 are started to drive the driving roller 302 to pull the conveying copper belt. The driving speed of the two copper belt control motors 301 is higher than that of the conveying motor 104. At this time, as the copper belt control motor 301 is driven, the copper belt will be pulled, and the reverse force of the copper belt is used to pull back the sliding frame 201. At this time, the connecting spring 203 on the two sliding frames 201 is compressed, and the pressure sensor 202 squeezes the conveying mounting frame 101. The external display of the two pressure sensors 202 is used to understand the current pulling force, to ensure that the pulling force of the two copper strips is consistent and within a suitable range to prevent the copper strips from being damaged by pulling. The staff observes the detection of the two pressure sensors 202 and adjusts the speed of the two copper strip control motors 301. In the process of the two copper strips being conveyed, the upper negative pressure shell 602 and the lower negative pressure shell 501 are sucked by the external vacuum pump, and the welding gun head 603 is used in real time. The weld of the copper strip is welded, and the bubbles in the molten pool that is not completely solidified are eliminated under the action of negative pressure. As the copper strip is continuously conveyed, the upper negative pressure shell 602 and the lower negative pressure shell 501 are attached to the surfaces of the two copper strips and sealed. The electric heating wire in the weld laminating plate 403 is energized to heat the weld, and the weld that is not welded and closed is attached and sealed. When the copper strip is welded and conveyed, the tension spring 702 can pull the lower pressure column 701 downward, and the scraper shell 703 is attached to the surface of the weld path, scraping and pressing down. The inclined scraper shell 703 can also flatten the semi-solidified molten material in the molten pool. The scraper wheel 502 is 603 meters away from the welding gun head. The molten material in the molten pool is basically solidified when it reaches the position of the scraping wheel 502. At this time, the scraping wheel 502 can be used to scrape and remove the solidified molten material protruding from the bottom of the weld path. The scraping wheel 502 can be driven to rotate and scrape by starting the driving motor 503. The scraped slag can be easily discharged by unscrewing the cover plate 601. The bottom of the upper limit plate 402 is used to fit the copper belt. At this time, the inward motor 801 drives the opposite seam-closing rod 802 to rotate, and the spiral protrusion 803 is used to fit and rub against the bottom of the copper belt. The copper belt is controlled to retract inward to fit the weld seam fitting plate 403 to keep the weld seam accurate.
