Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel strand cutting technology, and specifically to a steel strand cutting device. Background Technology
[0002] Steel strand is a steel product made of multiple strands of steel wire twisted together. It undergoes stress-relieving and stabilization treatments to ensure stable performance during use. A layer of zinc or zinc alloy is plated onto the surface of carbon or low-alloy structural steel wire, giving the steel strand high strength, low relaxation, good ductility and flexibility, and enhancing its corrosion resistance. Due to these excellent physical and chemical properties, steel strand is widely used in various engineering fields such as bridges, power plants, water conservancy projects, and road fences. In engineering construction, steel strand plays a crucial role in prestressed concrete engineering. During construction, the steel strand is first threaded into pre-drilled holes in the concrete structure using a strand-threading machine. Then, anchors, jacks, and other tools are used to tension the steel strand, applying compressive stress to the concrete structure. Because the concrete structure is subjected to prestress, its load-bearing capacity and stability are significantly enhanced, thereby significantly improving its load-bearing capacity, stability, and crack resistance, and ultimately extending the service life of concrete buildings.
[0003] Steel strand manufacturers typically ship their products in coils for easy transport. Upon arrival at the construction site, these coils need to be cut into multiple strands according to specific construction requirements. Due to the high strength of steel strands, manually cutting them on-site using tools like grinders would be extremely time-consuming. Therefore, cutting devices are used to cut the steel strands. Among various cutting devices, arc cutting and abrasive wheel cutting are commonly used. While arc cutting is fast, the electric arc generates high temperatures at the cutting point, which can damage the mechanical properties of the steel strand and reduce its stability. Abrasive wheel cutting, although slower than arc cutting, has less impact on the steel strand and does not require high-voltage maintenance. Therefore, in practical applications, abrasive wheel cutting is widely used for cutting steel strands.
[0004] For cutting steel strands, cutting the ends at flat angles facilitates fixing and connection with other components or devices. Cutting the ends at bevels reduces resistance when penetrating pre-drilled holes in concrete structures, allowing the strands to be transported more smoothly along the predetermined path. However, to facilitate cutting strands at different angles using cutting devices, workers need to manually adjust the cutting angle of the grinding wheel before cutting. This manual adjustment is cumbersome and lacks precision. Furthermore, to improve cutting efficiency, multiple strands are often cut at once. This results in beveled and flat-ended strands being mixed together after cutting, requiring workers to sort them, increasing their workload. Therefore, there are shortcomings in steel strand cutting methods. A solution is needed to adjust the cutting angle, facilitate sorting, and improve cutting efficiency to meet the needs of engineering construction. Summary of the Invention

[0008] Preferably, there are at least two guide plates, and several guide plates are located on the same horizontal plane. A linkage mechanism is provided between two adjacent guide plates. The linkage mechanism includes two vertically arranged circular tubes and an n-shaped tie rod between the two circular tubes. The vertical rods on both sides of the tie rod are respectively movably fitted into the two circular tubes. The two circular tubes are respectively installed on the side walls of two adjacent guide plates. The top of the tie rod is not higher than the height of the top surface of the guide plate. One end of each of the several guide plates is vertically provided with a second hinge. One end of the guide plate is hinged to the bracket through the second hinge. One end of the guide plate is not lower than the height of the other end of the guide plate.
[0009] Preferably, a support base is provided on the side of the grinding wheel away from the bracket. The support base is mounted on the frame, and the top surface of the support base and the top surface of the baffle are on the same plane. Two support bars are respectively provided on the top surface of the support base, and the two support bars are respectively installed on both sides of the top surface of the support base. A fixed frame and a second motor are respectively provided on the side of the support base away from the grinding wheel. The second motor and the fixed frame are both mounted on the support base, and a conveying mechanism is provided between the fixed frame and the second motor.

A screw is vertically provided on one side of the bearing seat, and the top of the screw is mounted on the fixed seat. The top plate of the frame has a fixed groove with an arc structure. The center of the fixed groove and the rotation center of the bearing seat are located on the same axis. The screw is movably fitted on the fixed groove, and a nut is threaded on the screw.

[0012] The beneficial effects of this utility model are as follows: First, the utility model uses a first motor to drive the grinding wheel to rotate so that the grinding wheel can be used to cut the steel strand. Second, the utility model uses a telescopic cylinder to control the fixed plate to rotate around the hinge between the fixed seat and the fixed plate, thereby driving the grinding wheel to move towards the frame so as to cut the steel strand placed on the frame. Furthermore, this invention utilizes a telescopic cylinder II to rotate the fixed base, thereby rotating the grinding wheel to control the cutting angle. This facilitates the cutting of steel strands with flat or chamfered ends. By controlling the length of the telescopic cylinder II, the length of the cut steel strands can be precisely controlled to meet the need for rapid adjustment of the cutting angle. A partition rod divides the storage space of the bracket. A guide plate hinged to the bracket guides the steel strands to the storage space on one side of the partition rod. A telescopic cylinder III, located between the guide plate and the bracket, rotates the guide plate. When the guide plate is against the side of the bracket, the cut steel strands fall into the storage space on the other side of the partition rod. This allows steel strands with different end structures to be placed in the storage spaces on both sides of the partition rod, meeting the need for categorized placement of the steel strands.
[0013] Secondly, this invention uses two support plates at the top of the bracket and two support bars on the support base to form a conveying channel for the steel strand, preventing the steel strand from swaying left and right during the cutting process. The baffle and support base further support the steel strand, ensuring stability during cutting. After cutting, the cut steel strand falls onto the baffle. A telescopic cylinder, hinged at both ends to the baffle and the bracket, causes the baffle to rotate around the hinge during its extension and retraction, allowing the cut steel strand to fall into the storage space of the bracket. This controls the conveying of the steel strand and improves the stability of the cutting process. Furthermore, multiple guide plates provide support at multiple points on the cut steel strand, allowing it to be conveyed along the top of the guide plates. A circular tube and pull rod control the simultaneous rotation of multiple guide plates.
[0014] Furthermore, this invention utilizes a second motor and gears to drive two rotating shafts to rotate in opposite directions. The steel strand passes between pressure rollers mounted on the two shafts, which then move the steel strand to facilitate cutting. Additionally, the invention employs a screw mounted on the fixed base, a nut threaded onto the screw, and a circular arc-shaped fixing groove on the frame to clamp the fixed base onto the frame, reducing shaking during cutting and improving the cutting efficiency. A fixing frame on the fixed base constrains the movement of the fixing block, which is connected to a fixing plate via a fixing rod, thus constraining the rotation of the fixing plate and preventing the first motor or grinding wheel on the fixing plate from colliding with the frame.

[0023] like Figures 1 to 8As shown, a steel strand cutting device includes a frame 1, a first motor 2 mounted on the frame 1, and a grinding wheel 3 connected to the drive end of the first motor 2, thereby using the first motor 2 to drive the grinding wheel 3 to cut the steel strand. A fixed base 4 is rotatably mounted on the top of the frame 1, and a fixed plate 5 is hinged to the top of the fixed base 4. The first motor 2 is mounted on the fixed plate 5. A telescopic cylinder 6 is provided between the fixed base 4 and the fixed plate 5, with its two sides hinged to the fixed base 4 and the fixed plate 5 respectively. The device controls the extension of the telescopic cylinder 6. The device retracts to rotate the fixed plate 5 around the hinge point between the fixed base 4 and the fixed plate 5, thereby moving the grinding wheel 3 toward the frame 1 to cut the steel strand placed on the frame 1. The fixed base 4 and the frame 1 are equipped with a telescopic cylinder 7, with its two sides hinged to the fixed base 4 and the frame 1 respectively. The device controls the extension and retraction of the telescopic cylinder 7 to rotate the fixed base 4, thereby rotating the grinding wheel 3 and facilitating the cutting of the steel strand at various angles. A support 8 is provided on one side of the frame 1. The support 8 consists of vertical rods, horizontal rods, and longitudinal rods. A telescopic cylinder 3.9 is horizontally mounted on the top of the support 8. A guide plate 10 is hinged to one side of the telescopic cylinder 3.9, with one end of the guide plate 10 hinged to the support 8. A partition rod 11 is vertically mounted in the middle of the support 8, with its bottom end installed on the support 8 and its top end not exceeding the top of the support 8. The other end of the guide plate 10 contacts the partition rod 11. The support 8 is used to hold cut steel strands, and the partition rod 11 separates the storage space of the support 8. One side of the support 8... Outside the grinding wheel 3, the guide plate 10 is located below the grinding wheel 3. The guide plate 10 is used to guide the cut steel strands into the storage space of the bracket 8 on one side of the partition rod 11. By controlling the retraction action of the telescopic cylinder 3 9, the guide plate 10 is rotated so that the other end of the guide plate 10 is attached to the side of the bracket 8, so that the cut steel strands fall into the storage space of the bracket 8 on the other side of the partition rod 11, so that steel strands with different joint structures can be placed in the storage spaces on both sides of the partition rod 11 to meet the needs of steel strand classification and placement.

The telescopic cylinder 16 is located outside the baffle 14, thereby preventing the rotation of the baffle 14 from colliding with the telescopic cylinder 16. The two support plates 12 form a steel strand conveying channel, and the baffle 14 is used to support the steel strand. After the steel strand is cut, it falls onto the baffle 14. By controlling the telescopic cylinder 16 to retract, the baffle 14 is driven to rotate around the hinge 15, so that the cut steel strand slides off the baffle 14 and falls into the storage space of the bracket 8, so as to control the conveying of the steel strand and improve the stability of the steel strand cutting.

The pull rod 18 drives the remaining guide plate 10 to rotate. The top of the pull rod 18 is not higher than the top surface of the guide plate 10, so as to prevent the pull rod 18 from affecting the steel strand conveyed by the guide plate 10. Each of the guide plates 10 has a hinge 2 19 vertically installed at one end. One end of the guide plate 10 is hinged to the bracket 8 through the hinge 2 19. One end of the guide plate 10 is not lower than the height of the other end of the guide plate 10, so as to facilitate the use of the guide plate 10 to guide the steel strand to the storage space of the bracket 8 on one side of the partition rod 11.

The top surface of the support base 20 and the top surface of the baffle 14 are on the same plane. Two support bars 21 are respectively provided on the top surface of the support base 20. The two support bars 21 are respectively installed on both sides of the top surface of the support base 20, thereby forming a steel strand conveying channel between the two support bars 21.

The support base 20 is used to support the steel strand to ensure the stability of the cutting steel strand. A fixed frame 22 and a second motor 23 are respectively provided on the side of the support base 20 away from the grinding wheel 3. The second motor 23 and the fixed frame 22 are both installed on the support base 20. A conveying mechanism is provided between the fixed frame 22 and the second motor 23. The conveying mechanism includes two rotating shafts 24 rotatably mounted on the fixed frame 22. Each of the two rotating shafts 24 is provided with a support bar on one side. The pressure roller 25 and the other side of the two rotating shafts 24 are each equipped with a gear 26. The gear 26 and the pressure roller 25 are respectively installed on both sides of the rotating shaft 24. The second motor 23 is connected to one of the rotating shafts 24. One rotating shaft 24 is located below the other rotating shaft 24. The gears 26 installed on the two rotating shafts 24 mesh with each other to drive the two rotating shafts 24 to rotate. By passing the steel strand through the pressure roller 25 installed on the two rotating shafts 24, the pressure roller 25 pushes the steel strand to move, so as to push the steel strand to perform cutting. Furthermore, the number of conveying mechanisms is not less than two. Several conveying mechanisms are arranged sequentially on the fixed frame along the horizontal direction. The transmission gears between adjacent conveying mechanisms mesh with the gears 26 of the two adjacent conveying mechanisms on both sides, thereby driving the two adjacent conveying mechanisms so that the second motor 23 drives multiple conveying mechanisms to operate.
[0027] In this embodiment, a bearing seat 27 is provided on the top of the frame 1. The fixed seat 4 is rotatably mounted on the frame 1 through the bearing seat 27. By controlling the extension and retraction of the telescopic cylinder 2 7, the fixed seat 4 is driven to rotate around the rotation center of the bearing seat 27.

A nut 30 is threaded on the screw 28. The outer wall length of the nut 30 is not less than the groove width of the fixed groove 29. The screw 28 and the fixed seat 4 are clamped and fixed on the top plate of the fixed seat 4 by the nut 30, thereby reducing the shaking of the fixed seat 4 during the cutting process and improving the cutting effect of the steel strand.
[0028] Please refer to Figure 1 and 3A fixing rod 31 is inclinedly arranged below the fixing plate 5. The top end of the fixing rod 31 is installed on the fixing plate 5. A fixing block 32 is arranged on one side of the fixing rod 31 and is installed on the bottom end of the fixing rod 31. A fixing frame 33 is arranged on the fixing seat 4. The fixing block 32 is located in the inner cavity of the fixing frame 33, thereby constraining the rotation angle of the fixing plate 5 to prevent the first motor 2 or the grinding wheel 3 on the fixing plate 5 from colliding with the frame 1.
[0029] The instructions for using this product are as follows: Figures 1 to 8 As shown, firstly, the free end of the coiled steel strand is passed between the pressure rollers 25 mounted on the two rotating shafts 24. The second motor 23 is controlled to operate, driving the two rotating shafts 24 to rotate. This uses the pressure rollers 25 to push the steel strand towards the support 8, allowing the free end of the steel strand to pass between the support bars 21 and into the space between the two support plates 12. Then, when the length of the steel strand on one side of the grinding wheel 3 reaches the cutting dimension, the second motor 23 is stopped, the first motor 2 is started, and the telescopic cylinder 6 is extended, allowing the grinding wheel 3 to cut the steel strand, causing it to fall onto the baffle 14 between the two support plates 12. Next, the telescopic cylinder 16 is retracted, causing the baffle 14 to rotate, allowing the steel strand to fall onto the guide plate 10, thus placing it into the storage space of the support 8 on one side of the partition rod 11. If it is necessary to cut the end of the steel strand at an angle, first control the telescopic cylinder 7 to extend and retract to adjust the cutting angle of the grinding wheel 3. Tighten the nut 30 to clamp the fixed seat 4 on the frame 1, so that the grinding wheel 3 can be used to cut the end of the steel strand at an angle. Then, control the telescopic cylinder 9 to retract to drive the guide plate 10 to rotate, so that the guide plate 10 fits against the side of the bracket 8, so that the cut steel strand falls into the storage space of the bracket 8 on the other side of the partition 11, thereby meeting the cutting requirements of the steel strand.
[0030] In this embodiment, the first motor 2 drives the grinding wheel 3 to rotate so that the grinding wheel 3 can be used to cut the steel strand. The telescopic cylinder 6 controls the fixed plate 5 to rotate around the hinge between the fixed base 4 and the fixed plate 5, thereby driving the grinding wheel 3 to move toward the frame 1 so as to cut the steel strand placed on the frame 1. Furthermore, this invention utilizes a telescopic cylinder 2 7 to rotate the fixed base 4, thereby rotating the grinding wheel 3 to control the cutting angle. This facilitates the cutting of steel strands with flat or chamfered ends. Controlling the length of the telescopic cylinder 2 7 allows for precise control of the cut steel strand length, enabling rapid adjustment of the cutting angle. A partition rod 11 divides the storage space of the bracket 8. A guide plate 10 hinged to the bracket 8 guides the steel strands to the storage space on one side of the partition rod 11. A telescopic cylinder 3 9, located between the guide plate 10 and the bracket 8, rotates the guide plate 10. When the guide plate 10 is against the side of the bracket 8, the cut steel strands fall into the storage space on the other side of the partition rod 11. This allows steel strands with different end structures to be placed in the storage spaces on both sides of the partition rod 11, satisfying the need for categorized steel strand placement.
