Description

Technical Field

[0001] The invention relates to the technical field of steel strand cross-section polishing, and in particular to an aluminum-clad steel prestressed steel strand cross-section polishing device and process. Background Art

[0002] Aluminum clad steel prestressed steel strand is made of 2, 3, 7 or 19 high-strength aluminum clad steel wires twisted into strands and subjected to stress relief treatment (stabilization treatment). It has excellent anti-corrosion properties, as well as the high strength and low relaxation properties of prestressed steel strands. It can be used for photovoltaic flexible brackets, cables and other similar purposes. Each single wire in the aluminum clad steel prestressed steel strand is in aluminum contact, and there is no galvanic cell effect, which can slow down the corrosion rate of the conductor. The corrosion rate of aluminum clad wire is much lower than that of galvanized steel wire. The bonding strength of aluminum and steel is high. Through extrusion and drawing, there is a good metallurgical bond between steel and aluminum. After a torsion test of more than 20 turns, the steel and aluminum on the cross section do not separate. Compared with galvanized steel wire of the same specification, the specific gravity is reduced by 15%, reducing the dosage.

[0003] Since the aluminum-clad steel prestressed steel strand is twisted into a strand by multiple high-strength aluminum-clad steel wires, when the cross-section of the aluminum-clad steel prestressed steel strand is polished, when the grinding force between the cross-section of the aluminum-clad steel prestressed steel strand and the polishing part is too large, the steel strand will shake during the polishing process, causing the steel strand to move under the action of the grinding force, which in turn leads to the phenomenon of loose steel wire.

At the same time, when the contact extrusion force between the metal impurities attached to the grinding disc and the contact block is greater than the tensile force of the second spring, the contact block slides on the inner side of the contact plate through the sliding rod, so as to avoid excessive extrusion force between the metal impurities attached to the grinding disc and the contact block, which would cause extrusion damage to the side surface of the contact block. At the same time, when the contact block slides toward the inner side of the contact plate through the sliding rod, the block moves on the inner side of the contact block through the sliding frame and the sliding shaft, so as to eject the impurities stuck in the contact block, so as to avoid a large amount of impurities being attached to the contact block when the contact block cleans the grinding disc for a long time, thereby interfering with the normal cleaning work of the contact block.

[0008] 4. The present invention provides an ejection mechanism. After the polishing work on the cross section of the aluminum-clad steel prestressed steel strand is completed and the air suction machine stops working, the grid frame is stretched by the reset of the third spring, so that the mesh plate drives the ejector pin through the ejection rod to eject some impurities stuck in the mesh of the mesh plate. At the same time, when the impurities stuck in the mesh of the mesh plate are tightly stuck to the inner side of the mesh, and the extrusion force between the ejector pin and the impurities is greater than the stretching force of the third spring, the ejector pin slides in the groove through the cylinder and the moving rod, thereby avoiding the phenomenon that the extrusion pressure between the impurities and the ejector pin is too large, which will squeeze and damage the impurities on the ejector pin, and at the same time cause the impurities to rub and squeeze with the inner wall of the mesh, thereby causing the inside of the mesh to expand.

Embodiment 2, use Figure 6-Figure 8 The cross-section polishing device for aluminum-clad steel prestressed steel strand of the present invention is described as follows: like Figure 6-Figure 8 The present invention shows an aluminum-clad steel prestressed steel strand cross-section polishing device, based on the first embodiment; The polishing component 5 includes a fixed frame 51, a water storage mechanism 52 is fixedly connected to the top of the fixed frame 51, water pipes 53 are fixedly connected to both sides of the water storage mechanism 52, a contact mechanism 55 is fixedly connected to the inner side of the water pipe 53, a spray frame 56 is fixedly connected to the bottom of the water pipe 53, a double-axis motor 57 is fixedly connected to the middle of the inner side of the fixed frame 51, and a polishing disc 58 is fixedly connected to the output end of the double-axis motor 57; when the cross section of the aluminum-clad steel prestressed steel strand is polished, the double-axis motor 57 is turned on and the polishing disc 58 is driven by the output end of the double-axis motor 57 The disc 58 rotates to grind the cross section of the aluminum-clad steel prestressed steel strand. At the same time, the water pump in the water storage mechanism 52 is turned on, so that the coolant in the water storage mechanism 52 enters the water pipe 53. At the same time, the coolant flows into the spray rack 56 through the water pipe 53. When the grinding disc 58 is grinding, the side of the grinding disc 58 can be cooled by the spray rack 56. At the same time, when the grinding disc 58 rotates, the contact mechanism 55 can contact and clean the side of the grinding disc 58.

At the same time, the suction force generated by the suction machine 43 causes the grid 46 to move downward through the telescopic rod 45, so that the grid 46 drives the ejection mechanism 48 to separate from the mesh of the mesh plate 42; The ejection mechanism 48 includes an ejection rod 481, the bottom of the ejection rod 481 is fixedly connected to the top of the grid 46, a notch 482 is provided on the side of the ejection rod 481, a cylinder 483 is slidably connected to the inner side of the notch 482, a moving rod 484 is fixedly connected to the side of the cylinder 483, an ejector pin 485 is fixedly connected to the top of the moving rod 484, a fourth spring 486 is sleeved on the moving rod 484, the top of the fourth spring 486 is fixedly connected to the bottom of the ejector pin 485, and the bottom of the fourth spring 486 is fixedly connected to the top of the ejection rod 481; when the polishing work on the section of the aluminum-clad steel prestressed steel strand is completed, the suction machine 43 stops working, and the grid The frame 46 is stretched by the reset of the third spring 47, so that the mesh plate 42 drives the ejector pin 485 through the ejector rod 481 to eject some impurities stuck in the mesh of the mesh plate 42. At the same time, when the impurities stuck in the mesh of the mesh plate 42 are tightly stuck to the inner side of the mesh, the extrusion force between the ejector pin 485 and the impurities is greater than the stretching force of the third spring 47, the ejector pin 485 slides in the slot 482 through the cylinder 483 and the moving rod 484, thereby avoiding the phenomenon that the extrusion force between the impurities and the ejector pin 485 is too large, which will squeeze and damage the impurities of the ejector pin 485, and at the same time cause the impurities to rub and squeeze the inner wall of the mesh, thereby causing the inner side of the mesh to expand. Embodiment 4, use Figure 1-Figure 10 The cross-section polishing device for aluminum-clad steel prestressed steel strand of the present invention is described as follows: like Fig.11 A process for polishing the cross section of an aluminum-clad steel prestressed steel strand is shown, comprising the following steps: S1: placing the cut aluminum-clad steel prestressed steel strand on the connecting component 3; S2: adjusting the position of the connecting component 3, and then polishing the cross section of the aluminum-clad steel prestressed steel strand through the polishing component 5; S3: Open the collecting component 4 to collect the metal scraps generated during the polishing of the cross section of the aluminum-clad steel prestressed steel strand; The specific workflow is as follows: During operation, the cut aluminum-clad steel prestressed steel strand is placed on the connecting component 3, so that the cross section of the aluminum-clad steel prestressed steel strand is polished by the polishing component 5, and at the same time, the metal scraps generated during the polishing of the cross section of the aluminum-clad steel prestressed steel strand are collected by opening the collecting component 4; After the aluminum-clad steel prestressed steel strand is placed on the clamping mechanism 33 for fixing, the motor 32 is turned on, and the output end of the motor 32 drives the screw rod 31 to rotate on the inner side of the workbench 1, thereby driving the clamping mechanisms 33 on both sides to move on the slide rod 34, so that the cross section of the aluminum-clad steel prestressed steel strand is polished by the polishing component 5; By placing the aluminum-clad steel prestressed steel strand in the limiting assembly 336, opening the electric hydraulic cylinders 332 on both sides, and driving the clamping plate 334 to move relatively through the output end of the electric hydraulic cylinder 332, the clamping plate 334 drives the limiting assembly 336 to clamp and fix the aluminum-clad steel prestressed steel strand through the connecting shaft 335; The output end of the electric hydraulic cylinder 332 drives the clamping plate 334 to move, and the clamping plate 334 drives the limit plate 3361 to move through the connecting shaft 335, so that the limit plate 3361 clamps and fixes the aluminum-clad steel prestressed steel strand. At the same time, when the aluminum-clad steel prestressed steel strand is fixed, since the aluminum-clad steel prestressed steel strand is twisted into a stranded wire by multiple high-strength aluminum-clad steel wires, when the cross-section of the aluminum-clad steel prestressed steel strand is polished, when the grinding force between the cross-section of the aluminum-clad steel prestressed steel strand and the polishing component 5 is too large, the steel strand will shake during the polishing process, causing the steel strand to be displaced under the action of the grinding force, thereby causing the steel wire to loosen. By arranging an electric rotating rod 3 on the inner side of the limit block 3362 363, by arranging a spiral block 3364 on the side of the electric rotating rod 3363, and the spiral block 3364 is made of rubber, so that after the limit plate 3361 clamps and fixes the aluminum-clad steel prestressed steel strand, when the polishing work is performed, the electric rotating rod 3363 is opened, so that the electric rotating rod 3363 drives the spiral block 3364 to contact and rotate with the aluminum-clad steel prestressed steel strand, so that when the cross section of the aluminum-clad steel prestressed steel strand is polished, multiple steel strands can be squeezed and rotated, and when the cross section of the aluminum-clad steel prestressed steel strand is polished, multiple high-strength aluminum-clad steel wires can be rotated and twisted, thereby avoiding displacement of the steel strand under the action of the grinding force, which leads to the phenomenon of loose steel wires; When the cross section of the aluminum-clad steel prestressed steel strand is polished, the double-shaft motor 57 is turned on, and the output end of the double-shaft motor 57 drives the grinding disc 58 to rotate, so as to polish the cross section of the aluminum-clad steel prestressed steel strand. At the same time, the water pump in the water storage mechanism 52 is turned on, so that the coolant in the water storage mechanism 52 enters the water pipe 53, and the coolant flows into the spray rack 56 through the water pipe 53. When the grinding disc 58 is polishing, the side of the grinding disc 58 can be cooled by the spray rack 56. At the same time, when the grinding disc 58 is rotating, the contact mechanism 55 can contact and clean the side of the grinding disc 58. When the grinding disc 58 is driven to rotate by the output end of the dual-axis motor 57, the contact plate 551 drives the contact block 555 to contact the side of the grinding disc 58, so that when the contact block 555 grinds the grinding disc 58, the metal impurities attached to the grinding disc 58 are scraped off. At the same time, when the contact extrusion force between the metal impurities attached to the grinding disc 58 and the contact block 555 is greater than the tensile force of the second spring 556, the contact block 555 slides on the inner side of the contact plate 551 through the sliding rod 554, thereby avoiding the metal impurities attached to the grinding disc 58 from being stuck. The extrusion force between the impurities and the contact block 555 is too large, which will cause extrusion damage to the side of the contact block 555. At the same time, when the contact block 555 slides toward the inner side of the contact plate 551 through the sliding rod 554, the block 558 moves inside the contact block 555 through the sliding frame 557 and the sliding shaft 559, thereby ejecting the impurities stuck in the contact block 555, thereby preventing the contact block 555 from being attached with a large amount of impurities when the contact block 555 cleans the polishing disc 58 for a long time, thereby interfering with the normal cleaning work of the contact block 555. When the aluminum-clad steel prestressed steel strand is polished, the suction machine 43 is turned on, and the suction force generated by the suction machine 43 is used to suck the metal scraps generated during the polishing work into the collection box 41 through the mesh plate 42 for collection, thereby avoiding the metal scraps generated during the polishing work on the aluminum-clad steel prestressed steel strand section from splashing. At the same time, the suction force generated by the suction machine 43 causes the grid frame 46 to move downward through the telescopic rod 45, so that the grid frame 46 drives the ejection mechanism 48 to separate from the mesh of the mesh plate 42; When the polishing work on the cross-section of the aluminum-clad steel prestressed steel strand is completed and the vacuum machine 43 stops working, the grid frame 46 is stretched by the reset of the third spring 47, so that the mesh plate 42 drives the ejector pin 485 through the ejector rod 481 to eject some impurities stuck in the mesh of the mesh plate 42. At the same time, when the impurities stuck in the mesh of the mesh plate 42 are tightly stuck to the inner side of the mesh, the extrusion force between the ejector pin 485 and the impurities is greater than the stretching force of the third spring 47, the ejector pin 485 slides in the slot 482 through the cylinder 483 and the moving rod 484, thereby avoiding excessive extrusion pressure between the impurities and the ejector pin 485, which will squeeze and damage the impurities of the ejector pin 485, and at the same time cause friction and extrusion between the impurities and the inner wall of the mesh, thereby causing the inside of the mesh to expand.
