Description
Technical Field
[0001] This invention relates to the field of ultrasonic welding technology, specifically to an automated punching and positioning device for angle steel of iron towers. Background Technology
[0002] In the automated punching process of angle steel for iron towers, the angle steel is usually held by a feeding trolley and conveyed forward along a hollow pressure roller (support roller) to the punching machine for punching and cutting. The pressure roller, as a direct support and guide component, has its outer circumference in continuous contact with the bottom surface of the outer corner of the angle steel and is passively rotated under the frictional force driven by the movement of the angle steel.
[0003] However, hot-rolled angle steel is covered with a dense oxide scale (mainly Fe3O4, with a hardness as high as HV500~1000), and a large amount of iron filings are generated during conveying and punching. In long-term continuous production, the oxide scale and iron filings gradually adhere to and accumulate on the outer surface of the lower pressure roller. Due to the extremely high hardness of the oxide scale, during the rolling friction of the roller, it is equivalent to continuous abrasive wear on the roller surface, resulting in uneven wear and an uneven surface on the outer circle of the lower pressure roller. When the lower pressure roller is severely worn in some areas, the height of its outer circle becomes uneven, and the support height and horizontal posture of the angle steel fluctuate when it is conveyed on the roller. The angle steel cannot maintain a stable positioning reference surface, which in turn causes twisting deformation and affects the punching accuracy of the angle steel. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an automated punching and positioning device for angle steel in iron towers, solving the problems of existing technologies.

[0008] Preferably, the spacing between the arc-shaped strips and the semi-arc strips is the same.
[0009] Preferably, one end of the fixing plate is fixedly connected to the punching machine, and the punching machine is provided with a scraping assembly, which includes a hydraulic cylinder fixedly installed on the back of the punching machine.
[0010] Preferably, an upper pressure roller is fixedly installed at the output end of the hydraulic cylinder, a mounting bracket is fixedly installed on the top of the housing of the upper pressure roller, and a rectangular rod is fixedly installed inside the mounting bracket.
[0011] Preferably, a T-shaped rotating rod is slidably mounted on the rectangular rod, and a compression spring is sleeved on the rectangular rod. The top end of the compression spring is fixedly connected to the mounting bracket, and the bottom end of the compression spring is fixedly connected to the T-shaped rotating rod.
[0012] Preferably, an arc-shaped limiting plate is rotatably mounted at the end of the T-shaped rotating rod, and two sliding rods are slidably mounted inside the arc-shaped limiting plate.
[0013] Preferably, an arc-shaped spring is fixedly installed on one side of the two sliding rods that are close to each other, and the arc-shaped spring is distributed within the arc-shaped limiting plate.
[0014] Preferably, inclined plates are hinged to the two sliding rods respectively, the bottom ends of the two inclined plates are hinged together, and limit grooves are formed on the two inclined plates respectively.
[0015] This invention provides an automated punching and positioning device for angle steel used in iron towers. Compared with existing technologies, it has the following advantages: 1. By setting up a cleaning component, the arc-shaped strips on the hollow pressure roller, under the gravity of the angle steel, rotate and squeeze the oxide scale and iron filings on the surface of the angle steel. The oxide scale is squeezed into fragments and falls into the gaps between the arc-shaped strips along with the iron filings, thereby reducing the wear of the hollow pressure roller on the iron filings. This prevents the hollow pressure roller from becoming uneven in height due to long-term wear, which would cause the angle steel to become misaligned and twisted during transportation, resulting in slanted holes and cross-sections punched by the punching machine, affecting the quality of the finished angle steel. The oxide scale and iron filings in the gaps within the arc-shaped strips are further compressed by gravity and the rotation angle. The rolled material enters the gap between the semi-circular strips and then flows through the gaps in the arc-shaped blocks into the hollow pressure roller. This prevents iron filings and oxide scale from accumulating in the gaps between the arc-shaped strips, which would fill the gaps and prevent the arc-shaped strips from peeling off the oxide scale from the subsequent angle steel. After the angle steel leaves the pressed semi-circular strips, the arc-shaped blocks will cause the rubber ball to reset and impact the inner wall of the hollow pressure roller, producing a slight deformation. This allows the oxide scale and iron filings in the gaps between the arc-shaped strips to roll smoothly, preventing large pieces of oxide scale from getting stuck in the gaps and causing blockages that would affect the peeling process on the angle steel surface.
[0016] 2. Through the synergy of the arc-shaped block, L-shaped plate, and T-shaped rod, when the angle steel presses down on the top arc-shaped block, the descending L-shaped plate will drive the bottom arc-shaped block to rise. Iron filings and oxide scale in the hollow pressure roller will be discharged from the gap opened by the bottom arc-shaped block into the Y-shaped groove, preventing the accumulation of iron filings and oxide scale in the hollow pressure roller and causing the arc-shaped block to get stuck. When the hollow pressure roller rotates one revolution, the rubber ball will hit the inner wall of the hollow pressure roller four times. The frequent impact of the rubber ball will increase the deformation frequency of the inner wall of the hollow pressure roller, thereby realizing timely cleaning of iron filings and oxide scale in the hollow pressure roller and enhancing the unblocking efficiency of oxide scale and iron filings in the gap of the arc strip. This ensures that the arc strip can stably and effectively peel off the oxide scale on the angle steel, avoiding the impact of the oxide scale on the angle steel on the punching accuracy when the angle steel enters the punching machine.
[0017] 3. By setting up a scraping assembly, when the hydraulic cylinder drives the upper pressure roller to descend, the inclined plate will first contact the inner surface of the angle steel, so that the sides of the two inclined plates are tightly attached to the inner wall of the angle steel. In conjunction with the lower pressure roller, the angle steel is positioned and clamped. Since the angle between the two inclined plates is greater than the angle of the angle steel under normal conditions, the arc spring can achieve tight attachment for angle steels of different angles, improving the applicability of the device. When the angle steel moves, the inclined plate scrapes off the oxide scale and iron filings on the inner surface of the angle steel. The scraped iron filings will leave the angle steel along the inclined surface of the inclined plate, preventing the cutter from suffering severe wear after long-term cutting of oxide scale and iron filings during the shearing of the angle steel. When the oxide scale and iron filings leave the angle steel along the inclined surface of the inclined plate, they will enter the limiting groove. The limiting groove, in conjunction with the inclined surface of the inclined plate, allows the iron filings and oxide scale to leave the angle steel quickly under the guidance, preventing the oxide scale and iron filings from accumulating on the inclined surface of the inclined plate, flipping over the inclined plate and entering the punching machine, which would affect the punching quality of the angle steel.

[0020] 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.
[0021] See Figures 1-11The present invention provides the following three technical solutions: First embodiment: An automated punching and positioning device for angle steel of iron towers, including a punching machine 1, a base plate 101 on the back of the punching machine 1, a fixing plate 102 above the base plate 101, and a plurality of Y-shaped support plates 103 on the top of the base plate 101, each Y-shaped support plate 103 penetrating the fixing plate 102. Y-shaped grooves are provided on each of the Y-shaped support plates 103, and two mounting seats 104 are fixedly installed in each of the Y-shaped grooves. Hollow pressure rollers 105 are rotatably mounted on each of the two mounting seats 104. The two hollow pressure rollers 105 on the Y-shaped support plates 103 are arranged in a V-shape. The device also includes: Several cleaning components are mounted on a hollow pressure roller 105. A rectangular column 106 is disposed inside the hollow pressure roller 105. Several arc-shaped strips 107 are fixedly installed on the outer wall of the hollow pressure roller 105. Several arc-shaped blocks 108 are slidably installed inside the hollow pressure roller 105, sliding through the hollow pressure roller 105. Several semi-arc strips 110 are fixedly installed on the outer wall of each of the arc-shaped blocks 108, and the arc-shaped blocks 108 are positioned close to each other. Limiting springs 109 are fixedly installed on the side closest to each other, and the ends of several limiting springs 109 that are close to each other are fixedly connected to rectangular columns 106; two connecting plates 111 are fixedly installed on the side of the two corresponding arc blocks 108 that are close to each other, and rubber balls 112 are fixedly installed on the ends of several connecting plates 111 that are far from each other; a sloping groove 113 is provided on the Y-shaped support plate 103, and the sloping groove 113 communicates with the Y-shaped groove; a collection groove 114 is provided on the top of the fixing plate 102.
[0022] In use, the angle steel is placed on several hollow lower pressure rollers 105, and then the end of the angle steel is clamped by the clamping pliers on the feeding trolley. Then, the feeding trolley is started to move the angle steel towards the feed inlet of the punching machine 1. When the front end of the angle steel enters the feed inlet, the hydraulic cylinder 2 is started. The hydraulic cylinder 2 drives the upper pressure roller 201 to descend and contact the inner surface of the angle steel. The clamping of the upper pressure roller 201 and the hollow lower pressure rollers 105 ensures that the angle steel will not tilt. The angle steel enters the punching machine 1 under the push of the feeding trolley to complete the punching and shearing.
[0023] As the feeding trolley moves the angle steel on the hollow pressure roller 105, the friction of the angle steel causes the hollow pressure roller 105 to rotate. The arc-shaped strips 107 on the hollow pressure roller 105, under the weight of the angle steel, compress the surface of the angle steel, squeezing out the oxide scale and iron filings. The oxide scale is crushed into fragments by the arc-shaped strips 107, and together with the iron filings, falls into the gaps between the arc-shaped strips 107. This reduces the wear of the hollow pressure roller 105 on the iron filings and prevents the hollow pressure roller 105 from becoming uneven in height over long-term wear. If the angle steel is not positioned accurately during transportation, it may twist and deform. This causes the punching and cutting machine 1 to punch oblique holes and cut beveled surfaces during punching and shearing, affecting the quality of the finished angle steel. When the hollow pressure roller 105 rotates, the angle steel will squeeze against several semi-circular strips 110. The semi-circular strips 110 will drive the arc-shaped block 108 to descend. Since the gaps between the arc-shaped strip 107 and the semi-circular strips 110 are connected, scale and iron filings in the gaps within the arc-shaped strip 107 will roll into the gaps between the semi-circular strips 110 due to gravity and changes in the rotation angle. Some of these will be squeezed out by the angle steel. The arc-shaped block 108 enters the hollow pressure roller 105 through its gap, preventing iron filings and oxide scale from accumulating in the gaps of the arc-shaped strip 107. This would fill the gaps in the arc-shaped strip 107, preventing it from peeling off the oxide scale from the subsequent angle steel. Another portion will fall directly into the Y-shaped groove along the gaps in the arc-shaped strip 107. After the angle steel leaves the pressed semi-arc strip 110, the corresponding arc-shaped block 108 will reset under the elastic force of the limiting spring 109. The arc-shaped block 108 will then drive the connecting plate 111 to reset. The connecting plate 111 will... The rubber ball 112 impacts the inner wall of the hollow pressure roller 105 on both sides of the reset arc block 108. The hollow pressure roller 105 is made of spring steel with elasticity, hardness and impact toughness or other materials with elasticity, hardness and impact toughness. After the rubber ball 112 impacts the inner wall of the hollow pressure roller 105, it will produce a slight deformation, which will allow the oxide scale and iron filings in the gaps of several arc strips 107 to roll smoothly, avoiding large pieces of oxide scale from getting stuck in the gaps of the arc strips 107 and causing blockage, thus preventing blockage from affecting the peeling work on the angle steel surface.
[0024] The second implementation method differs from the first implementation method mainly in that: Figure 5 and Figure 6 As shown, the cleaning assembly also includes several L-shaped plates 115 disposed inside the hollow pressure roller 105. The L-shaped plates 115 are divided into two groups of two. The ends of the two groups of L-shaped plates 115 that are close to each other are respectively hinged to T-shaped round rods 116. Both T-shaped round rods 116 are rotatably connected to the rectangular column 106. The ends of the L-shaped plates 115 that are far from each other are respectively fixedly connected to symmetrical arc blocks 108.
[0025] When the angle steel presses down on the top arc-shaped block 108, the arc-shaped block 108 will cause the L-shaped plate 115 to descend. At this time, the L-shaped plate 115 will cause one end of the T-shaped rod 116 to descend, and the T-shaped rod 116 will rotate. Correspondingly, the T-shaped rod 116 will cause the L-shaped plate 115 on the symmetrical plane of the arc-shaped block 108 to rise. The corresponding L-shaped plate 115 will cause the bottom arc-shaped block 108 to rise. At this time, the iron filings and oxide scale in the hollow pressure roller 105 will be discharged from the gap opened by the bottom arc-shaped block 108 into the Y-shaped groove, and then enter the collection groove 11 through the inclined groove 113. The rubber ball 112 collects iron filings and oxide scale inside the hollow pressure roller 105 to prevent them from accumulating and causing the arc block 108 to get stuck. When the hollow pressure roller 105 rotates once, the rubber ball 112 will hit the inner wall of the hollow pressure roller 105 four times. The frequent impact of the rubber ball 112 will improve the cleaning of iron filings and oxide scale on the inner wall of the hollow pressure roller 105, and enhance the unblocking efficiency of oxide scale and iron filings in the gap of the arc strip 107. It will also enhance the peeling effect of the arc strip 107 on the oxide scale on the angle steel, and prevent the oxide scale on the angle steel from affecting the punching accuracy of the angle steel when it enters the punching machine 1.
[0026] The third implementation method differs from the first and second implementation methods mainly in that: Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the spacing between several arc-shaped strips 107 and several semi-arc strips 110 is the same; one end of the fixed plate 102 is fixedly connected to the punching machine 1, and the punching machine 1 is equipped with a scraping assembly, which includes a hydraulic cylinder 2 fixedly installed on the back of the punching machine 1; an upper pressure roller 201 is fixedly installed at the output end of the hydraulic cylinder 2, and a mounting bracket 202 is fixedly installed on the top of the housing of the upper pressure roller 201, and a rectangular rod 203 is fixedly installed inside the mounting bracket 202; a T-shaped rotating rod 205 is slidably installed on the rectangular rod 203, and a compression spring 204 is sleeved on the rectangular rod 203. The top end of the compression spring 204 is fixedly connected to the mounting bracket 202, and the bottom end of the compression spring 204 is fixedly connected to the T-shaped rotating rod 205. An arc-shaped limiting plate 206 is rotatably installed at the end of the T-shaped rotating rod 205, and two sliding rods 207 are slidably installed inside the arc-shaped limiting plate 206. An arc-shaped spring 208 is fixedly installed on the side of the two sliding rods 207 that are close to each other, and the arc-shaped springs 208 are distributed inside the arc-shaped limiting plate 206. An inclined plate 209 is hinged to each of the two sliding rods 207, and the bottom ends of the two inclined plates 209 are hinged together. A limiting groove 210 is opened on each of the two inclined plates 209.
[0027] When hydraulic cylinder 2 drives the upper pressure roller 201 to descend, hydraulic cylinder 2 will drive the mounting bracket 202 to descend synchronously. The mounting bracket 202 will drive the T-shaped rotating rod 205 to descend, the T-shaped rotating rod 205 will drive the arc-shaped limiting plate 206 to descend, the arc-shaped limiting plate 206 will drive the sliding rod 207 to descend, and the sliding rod 207 will drive the inclined plate 209 to descend. The inclined plate 209 will first contact the inner surface of the angle steel. As hydraulic cylinder 2 continues to descend, compression spring 204 will undergo compression deformation, generating a downward force that keeps the sides of the two inclined plates 209 tightly against the inner wall of the angle steel. At the same time, while the inclined plates 209 are tightly against the two inner surfaces of the angle steel, the arc-shaped spring 208 will undergo compression deformation. Since the angle between the two inclined plates 209 is greater than the angle of the angle steel under normal conditions, the arc-shaped spring 208 can achieve tight contact with angle steel at different angles, improving the applicability of the device. When the upper pressure roller 201 presses against the angle steel... After the inner surface is removed and the angle steel is moved, the inclined plate 209 scrapes off the oxide scale and iron filings on the inner surface of the angle steel. The scraped iron filings will leave the angle steel along the inclined surface of the inclined plate 209, preventing the oxide scale and iron filings from remaining on the inner surface of the angle steel and affecting the punching accuracy of the punching machine 1. At the same time, it prevents the cutter from suffering severe wear after long-term cutting of oxide scale and iron filings during the shearing of the angle steel. When the oxide scale and iron filings leave the angle steel along the inclined surface of the inclined plate 209, they will enter the limiting groove. Inside 210, because the limiting groove 210 is set on the inclined surface of the inclined plate 209, the iron filings and oxide scale entering the limiting groove 210 will be guided by the limiting groove 210 and quickly leave the angle steel along the path of the limiting groove 210, preventing the oxide scale and iron filings from accumulating on the inclined surface of the inclined plate 209. When the accumulation height is higher than the inclined plate 209, the oxide scale and iron filings will flip over the inclined plate 209 and enter the punching machine 1 along the moving angle steel, affecting the punching quality of the angle steel.
[0028] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0029] In use, the angle steel is placed on several hollow pressure rollers 105, and then the end of the angle steel is clamped by the clamping pliers on the feeding trolley. The feeding trolley is then started to move the angle steel towards the feed inlet of the punching machine 1. As the feeding trolley moves the angle steel on the hollow pressure rollers 105, the friction of the angle steel causes the hollow pressure rollers 105 to rotate. The arc-shaped strips 107 on the hollow pressure rollers 105 will press the surface of the angle steel under the action of its gravity, thus exposing the oxide layer on the surface of the angle steel. The scale and iron filings, among which the scale will be squeezed into pieces by the arc-shaped strips 107 and fall together with the iron filings into the gaps between the arc-shaped strips 107. When the hollow pressure roller 105 rotates, the angle steel will squeeze several semi-arc strips 110. The semi-arc strips 110 will drive the arc-shaped block 108 to descend. Since the gaps between the arc-shaped strips 107 and the semi-arc strips 110 are connected, the scale and iron filings in the gaps within the arc-shaped strips 107 will roll into the gaps between the semi-arc strips 110 on both sides due to the change in gravity and rotation angle. Part of the material will enter the hollow pressure roller 105 through the gap of the arc-shaped block 108 pressed down by the angle steel, and the other part will fall directly into the Y-shaped groove along the gap of the arc-shaped strip 107. After the angle steel leaves the half-arc strip 110 that is pressed down, the corresponding arc-shaped block 108 will be reset under the elastic force of the limit spring 109. The arc-shaped block 108 will drive the connecting plate 111 to reset. The connecting plate 111 will drive the rubber ball 112 to hit the inner wall of the hollow pressure roller 105 on both sides of the reset arc-shaped block 108. After the rubber ball 112 hits the inner wall of the hollow pressure roller 105, it will produce a slight deformation, so that the oxide scale and iron filings in the gap of several arc-shaped strips 107 can roll smoothly. When the angle steel presses down the top arc-shaped block 108, the arc-shaped block 108 will drive the L-shaped plate 115 to descend. At this time, the L-shaped plate 115 will drive one end of the T-shaped rod 116 to descend. The T-shaped rod 116 will rotate, and the corresponding T-shaped rod 116 will drive the L-shaped plate 115 on the symmetrical side of the arc-shaped block 108 to rise. The corresponding L-shaped plate 115 will drive the bottom arc-shaped block 108 to rise. At this time, the iron filings and oxide scale in the hollow pressure roller 105 will be discharged from the gap opened by the bottom arc-shaped block 108 into the Y-shaped groove, and then enter the collection groove 114 from the inclined groove 113 for collection. When the hollow pressure roller 105 rotates one revolution, the rubber ball 112 will hit the inner wall of the hollow pressure roller 105 four times. The frequent impact of the rubber ball 112 will improve the cleaning of iron filings and oxide scale on the inner wall of the hollow pressure roller 105. When hydraulic cylinder 2 drives the upper pressure roller 201 to descend, hydraulic cylinder 2 will drive the mounting bracket 202 to descend synchronously. The mounting bracket 202 will drive the T-shaped rotating rod 205 to descend, the T-shaped rotating rod 205 will drive the arc-shaped limiting plate 206 to descend, the arc-shaped limiting plate 206 will drive the sliding rod 207 to descend, and the sliding rod 207 will drive the inclined plate 209 to descend. The inclined plate 209 will first contact the inner surface of the angle steel. As hydraulic cylinder 2 continues to descend, compression spring 204 will undergo compression deformation, and compression spring 204 will generate a downward force, causing the sides of the two inclined plates 209 to press tightly against the inner wall of the angle steel. At the same time, while the inclined plates 209 are pressing tightly against the two inner surfaces of the angle steel, the arc-shaped spring 208 will undergo compression deformation. Since the angle between the two inclined plates 209 is greater than the angle of the angle steel under normal conditions, the arc spring 208 can achieve tight contact with angle steel at different angles. After the upper pressure roller 201 presses against the inner surface of the angle steel, and when the angle steel moves, the inclined plate 209 scrapes off the oxide scale and iron filings on the inner surface of the angle steel. The scraped iron filings will leave the angle steel along the inclined surface of the inclined plate 209. When the oxide scale and iron filings leave the angle steel along the inclined surface of the inclined plate 209, they will enter the limiting groove 210. Since the limiting groove 210 is set on the inclined surface of the inclined plate 209, the iron filings and oxide scale that enter the limiting groove 210 will quickly leave the angle steel along the path of the limiting groove 210 under the guidance of the limiting groove 210.
