Description

Technical Field

[0001] This utility model relates to the field of flux-cored welding wire production technology, specifically a flux-cored welding wire coating forming machine. Background Technology

[0002] Flux-cored welding wire is a welding material made of thin steel strips wrapped with flux or metal powder. Its structure is divided into tubular and folded types, and it has the function of combined gas and slag protection. It is widely used in automatic and semi-automatic welding.

[0003] Currently, the components for rolling steel strips inside flux-cored welding wire forming machines still have certain defects in actual use. Since the rolling of the steel strip is gradually formed by multiple rollers, during the rolling process, multiple rollers repeatedly contact the protective oil on the surface of the steel strip. The oil residue will repeatedly contact the inner wall of the rolled steel strip, resulting in a large amount of protective oil residue remaining on the inner wall after the steel strip is rolled. This can lead to hydrogen porosity problems during subsequent welding operations.

[0004] In view of this, a flux-cored welding wire coating forming machine was designed to solve the above problems. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0019] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a flux-cored welding wire coating forming machine.

[0020] Example 1: Combination Figures 1 to 4 As shown, the present invention provides a flux-cored welding wire coating forming machine, including a steel strip 300, a coiling mechanism 100 disposed outside the steel strip 300, and a strip surface degreasing mechanism 200 disposed on the coiling mechanism 100, wherein the strip surface degreasing mechanism 200 is located directly below the steel strip 300. The coiling mechanism 100 is used to provide effective stabilization and protection during the oil scraping of the steel strip 300, and the strip surface degreasing mechanism 200 is used to efficiently degrease the inner wall of the coiled steel strip 300.

[0021] The curling mechanism 100 includes two trusses 110, two supports 1101 fixedly installed at the bottom of the trusses 110, and a base support 1102 fixedly installed at the bottom of the two supports 1101. The winding mechanism 100 also includes a first winding wheel 130, a second winding wheel 140, and a third winding wheel 150. The first winding wheel 130 is movably mounted at one end of the two trusses 110 and is located directly above the two supports 1101. The second winding wheel 140 is movably mounted in the middle of the two trusses 110, and the third winding wheel 150 is movably mounted at the other end of the two trusses 110. The outer surfaces of the third roll wheel 150, the second roll wheel 140, and the first roll wheel 130 are all provided with U-shaped grooves, and the diameter and width of the U-shaped grooves in the third roll wheel 150, the second roll wheel 140, and the first roll wheel 130 gradually decrease. The surface degreasing mechanism 200 includes a second slide 220, a bushing 2101 movably installed inside two supports 1101, a first slide 210 fixedly installed on the bushing 2101, and a groove 2102 is provided inside the first slide 210, a pad 2103 is fixedly installed inside the groove 2102, a slider 2201 installed at one end of the second slide 220 and passing through the groove 2102, and the second slide 220 is located inside the first slide 210. A slide channel 2202 is provided inside the second slide 220, and the pad 2103 is adapted to pass through the slide channel 2202. The surface degreasing mechanism 200 also includes a first oil scraper 230, a second oil scraper 240 and a third oil scraper 250. The first oil scraper 230 passes through the first slide 210 and is inserted into the bushing 2101. The second oil scraper 240 is movably mounted on the pad 2103 and the third oil scraper 250 is movably mounted on the other end of the second slide 220. The dimensions of the third oil scraper 250, the second oil scraper 240, and the first oil scraper 230 gradually decrease.

[0022] The two first lead screws 120 are pre-adjusted until the first lead screws 120 are lifted upward along the inside of the base 1102. The clamp 1201, which is movably installed at the top of the first lead screws 120, will bring the surface degreasing mechanism 200 closer to the two trusses 110. The first roller 130, the second roller 140 and the third roller 150 will shorten the gap of the roller pressing at the first oil scraper 230, the second oil scraper 240 and the third oil scraper 250 respectively. When the steel belt 300 enters through the gap between the third reel 150 and the third oil scraper 250, it is subjected to the roller pressure drive of the third reel 150. The steel belt 300 is then subjected to the first oil scraping by the third oil scraper 250. After the rolled steel belt 300 enters the gap between the second reel 140 and the second oil scraper 240, the steel belt 300 will be further curled due to the reduced diameter of the second reel 140. The U-shaped inner wall of the curled steel belt 300 will then be subjected to the second oil scraping by the second oil scraper 240. Finally, the rolled steel belt 300 will enter the gap between the first reel 130 and the first oil scraper 230. At this time, the first oil scraper 230 will perform a third oil scraping process on the steel belt 300, thereby ensuring that no oil residue remains on the inner wall of the curled part of the steel belt 300.

[0023] Example 2: Combination Figure 2 and Figure 4 As shown, based on Embodiment 1, the curling mechanism 100 further includes a first lead screw 120, a clamp 1201 movably mounted on the top of the first lead screw 120, a first spring 160 disposed inside the two supports 1101, and the top of the first spring 160 is welded to the truss 110, and the bottom of the first spring 160 is welded to the bushing 2101. The top of the clip 1201 is provided with an arc-shaped groove adapted to be clamped in the bushing 2101; The base 1102 has a screw hole inside, and the first lead screw 120 is movably installed in the screw hole.

[0024] Preferably, the first roller 130, the second roller 140, and the third roller 150 are all mounted in the two trusses 110 via bearings. After the two first springs 160 are compressed, the gaps between the first roller 130, the second roller 140, and the third roller 150, which are evenly distributed in the vertical direction, and the first oil scraper 230, the second oil scraper 240, and the third oil scraper 250, respectively, can remain constant. This ensures that no blockage occurs during the gradual winding of the steel belt 300, thereby improving the smoothness of the delivery of the steel belt 300 after gradual winding.

[0025] Example 3: Combination Figure 4 As shown, based on Embodiment 1, the surface degreasing mechanism 200 further includes three oil drain pipes 260, a positioning clip 270 fixedly installed in the slider 2201, a movable clip 280 fixedly installed at the outer end of the second oil scraper 240, and a second lead screw 290 movably installed in the positioning clip 270. The movable clip 280 has a threaded hole inside, and the threaded section of the second lead screw 290 is adapted to pass through the threaded hole inside the movable clip 280.

[0026] Three oil drain pipes 260 are respectively fixedly installed on the first oil scraper 230, the second oil scraper 240 and the third oil scraper 250; Preferably, the first oil scraper 230, the second oil scraper 240 and the third oil scraper 250 are all provided with cylindrical oil removal cavities, and the three oil drain pipes 260 are respectively fixedly installed in the vertical pipes at the bottom of the first oil scraper 230, the second oil scraper 240 and the third oil scraper 250, and the oil drain pipes 260 are composed of L-shaped conduits and hoses.

[0027] The working principle and usage process of this utility model are as follows: The first roller 130, the second roller 140 and the third roller 150 are driven by an external drive device until the first roller 130, the second roller 140 and the third roller 150 maintain the same speed. Based on the thickness of the steel strip 300 to be processed, the two first lead screws 120 are adjusted to rotate forward until the two clamps 1201 are pushed and lift the strip surface degreasing mechanism 200 as a whole toward the two trusses 110 until the gap between the first oil scraper 230, the second oil scraper 240 and the third oil scraper 250 and the first winding wheel 130, the second winding wheel 140 and the third winding wheel 150 respectively gradually decreases until the steel strip 300 can be pressed and pass through the adjusted gap normally. Next, one end of the steel strip 300 is fed along the gap between the third reel 150 and the third oil scraper 250. Driven by the roller pressure of the third reel 150, the steel strip 300 is fed into the gap between the second reel 140 and the second oil scraper 240. After being driven by the roller pressure of the second reel 140, the steel strip 300 continues to be fed into the gap between the first reel 130 and the first oil scraper 230. At the same time, the surface of the steel strip 300 facing the third oil scraper 250, the second oil scraper 240, and the first oil scraper 230 is forced to shrink due to the pressure of the U-shaped gap. During the continuous curling process of the steel strip 300, the third oil scraper 250, the second oil scraper 240, and the first oil scraper 230 effectively scrape off the oil and impurities on its curled surface, thereby avoiding the problem of hydrogen porosity during subsequent welding.
