Description

Technical Field

[0001] This utility model relates to the field of steel plate production technology, specifically to an edge burr removal device for steel plate production. Background Technology

[0002] During the cutting, stamping, or shearing processes, irregular burrs may form on the edges of steel plates due to plastic deformation of the metal or wear of the cutting tools. These burrs not only affect the appearance quality of the steel plates but may also scratch operators, interfere with subsequent processing, and even reduce the mechanical properties of structural components. Therefore, burr removal is an indispensable process in steel plate production. Its core objective is to remove edge burrs through physical or chemical methods to ensure that the edges of the steel plates are flat and smooth, meeting the requirements of downstream processing or use.

[0003] Traditional burr removal methods often involve manual grinding or simple mechanical tools, which are inefficient and labor-intensive. Existing automated equipment (such as fixed grinding rollers and rotary belt sanders) are usually designed for standard shaped steel plates and are not well adapted to irregularly shaped steel plates (such as curved or asymmetrical edges), which means that manual monitoring is still required during the grinding process, which is quite inconvenient.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide an edge burr removal device for steel plate production, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an edge burr removal device for steel plate production, including a cylinder and a top plate horizontally fixed at the top opening of the cylinder. A limiting mechanism is provided inside the cylinder, and the limiting mechanism includes:

[0007] A ring-shaped scissor lift is slidably mounted on the inner wall of the bottom of the cylinder. A pulley is rotatably connected to the outer edge of its top and the center of the pulley. The same belt is wound around the grooves of multiple pulleys. A vertically mounted slider is rotatably connected to the top of the pulley. The slider passes through the top plate and is fixed with a fixing block. A hollow block is fixed to the top of the fixing block. A fixing shaft is fixed to the end of the pulley near the slider. The fixing shaft passes through the slider and the fixing block in sequence and is rotatably connected to each other. A drive motor is fixed to the top of one of the pulleys located in the middle of the top of the ring-shaped scissor lift.

[0008] A damping spring rod is fixed to one end of the hollow block near the center of the top plate. A horizontal roller is provided at the end of the damping spring rod away from the hollow block. The same straight scissor lift is provided at the top of the hollow block and the roller. A pulley assembly is provided at the top of the straight scissor lift. A fixed shaft passes through the hollow block and the straight scissor lift and is connected to the pulley assembly.

[0009] Furthermore, the top of the top plate has multiple sliding channels arranged in a ring array about the axial direction of the top plate, vertically penetrating and extending radially along the top plate. Each sliding channel has a sealing mechanism. A slider slides within the sliding channel. Each sliding channel corresponds to a plurality of pulleys rotatably connected to the outer edge of the top of the ring scissor lift. The hollow block is fixed to the top of the fixed block near the axis of the top plate. The top of the fixed block away from the axis of the top plate is provided with a grinding equipment body. A horizontal rotating platform is rotatably provided at the center of the top of the top plate. The pulley group includes pulleys rotatably provided at each node of the top of the flat scissor lift. The outer sides of the multiple pulleys are wound with the same belt. The fixed shaft passes through the hollow block and the flat scissor lift and is coaxially fixedly connected to the pulleys rotatably provided away from the axis of the top plate. The damping spring rod is axially aligned with the radial direction of the top plate.

[0010] Furthermore, multiple sliding channels II are provided on the inner wall of the bottom of the cylinder, arranged in a ring array about the axial direction of the cylinder and extending radially along the cylinder. One of the sliding channels II is embedded with a horizontally arranged electric push rod. The telescopic end of the electric push rod is oriented towards the cylinder axis. A limit block is fixed to the telescopic end of the electric push rod. The limit block is rotatably set at the position of the pulley I at the bottom of the annular scissor frame corresponding to the outer edge. The limit block slides in the sliding channel II. The cross-section of the slider I in the horizontal direction is rhomboid, and one of its diagonals is aligned with the radial direction of the top plate. A storage groove is provided on the inner side wall of the sliding channel I along the circumference of the top plate. The sealing mechanism includes multiple slider II that are slidably arranged in the storage groove.

[0011] Furthermore, the slider 2 has a placement channel extending radially through the top plate at the corner end near the center of the sliding channel 1. A horizontal wedge block 1 is fixed at each of the two corner ends of the slider 1 along the radial direction of the top plate. The length direction of the wedge block 1 is consistent with the radial direction of the top plate. A wedge block 2 is fixed inside the placement slot. The ends of the wedge block 1 away from the slider 1 have vertical inclined surfaces at both ends along the width direction of the sliding channel 1. The wedge block 1 and the wedge block 2 slide against each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the coordinated design of the annular scissor lift, pulley assembly, and damping spring rod, the device can automatically adapt to the edge contours of steel plates of different shapes. The motor drives multiple pulleys, which in turn drive multiple rollers to rotate. In conjunction with the rotating platform at the center of the top plate, the steel plate can be rotated, so that the grinding rollers of the grinding equipment can automatically track the edge of the steel plate, reducing manual intervention and improving grinding efficiency.

[0014] 2. A dynamic seal is formed by the wedge-shaped block structure of slider one and slider two in the sealing mechanism, similar to the opening and closing mechanism of a zipper. When slider one moves along sliding channel one, slider two slides outward or inward under the action of the wedge block, always sealing the channel gap, preventing debris from entering the cylinder and protecting the internal components of the cylinder to work normally.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see the appendix Figure 1 To be continued Figure 5 This utility model provides an edge burr removal device for steel plate production: it includes a cylinder 10 and a top plate 11 horizontally fixed at the top opening of the cylinder 10. A limiting mechanism is provided inside the cylinder 10, and the limiting mechanism includes:

[0027] The annular scissor lift 20 is slidably mounted on the inner wall of the bottom of the cylinder 10. A pulley 21 is rotatably connected to the outer edge and center of the top of the pulley 20. A single belt 22 is wound around the grooves of multiple pulleys 21. A vertically mounted slider 30 is rotatably connected to the top of the pulley 21. The slider 30 passes through the top plate 11 and is fixed to a fixing block 13. A hollow block 15 is fixed to the top of the fixing block 13. A fixing shaft is fixed to the end of the pulley 21 near the slider 30. The fixing shaft passes through the slider 30 and the fixing block 13 in sequence and is rotatably connected to each other. A drive motor is fixed to the top of one of the pulleys 21 located in the middle of the top of the annular scissor lift 20.

[0028] A damping spring rod 16 is fixed to one end of the hollow block 15 near the axis of the top plate 11. A horizontal roller 17 is provided at the end of the damping spring rod 16 away from the hollow block 15. The same straight scissor lift 18 is provided at the top of the hollow block 15 and the roller 17. A pulley assembly 19 is provided at the top of the straight scissor lift 18. A fixed shaft passes through the hollow block 15 and the straight scissor lift 18 and is connected to the pulley assembly 19.

[0029] The top plate 11 has multiple sliding channels arranged in a ring array about the axial direction of the top plate 11, vertically penetrating and extending radially along the top plate 11. Each sliding channel is equipped with a sealing mechanism. The slider 30 slides in the sliding channel. Each sliding channel corresponds to a plurality of pulleys 21 rotatably connected to the outer edge of the top of the annular scissor lift 20.

[0030] The hollow block 15 is fixed to one end of the top of the fixed block 13 near the axis of the top plate 11. The end of the top of the fixed block 13 away from the axis of the top plate 11 is provided with the grinding equipment body 14. A horizontal rotating table 12 is rotatably provided at the center of the top of the top plate 11.

[0031] The pulley assembly 19 includes pulleys rotatably mounted at each node on the top of the flat scissor lift 18. The same belt is wound around the outer side of the multiple pulleys 19. The fixed shaft passes through the hollow block 15 and the flat scissor lift 18 and is coaxially fixedly connected to the pulleys 19 located away from the axis of the top plate 11. The damping spring rod 16 is axially aligned with the radial direction of the top plate 11.

[0032] It should be noted that: the rotating table 12 is horizontally set at the top center of the top plate 11 and is used to place the steel plate to be processed. After the steel plate is placed, the rotating table 12 can drive the steel plate to rotate around its own axis to assist in the 360-degree edge processing. When the electric push rod is started, the limit block moves along the sliding channel to the axis of the cylinder 10, pushing the annular scissor frame 20 to extend or retract. During this period, the pulley 21 on the outer edge of the top of the annular scissor frame 20 moves synchronously to the center or centrifugal. The annular scissor frame 20 extends and retracts to adjust the initial position of the entire limiting mechanism to adapt to steel plates of different diameters or shapes. The position change of the pulley 21 is to maintain the tension of the belt 22 and thus always maintain the effectiveness of the synchronous transmission of multiple pulleys 21.

[0033] A bearing bracket is fixed at one end of the damping spring rod 16 near the axis of the top plate 11. A horizontally rotatable roller 17 is installed inside the bearing bracket. In one possible embodiment, the grinding equipment body 14 slides on the top of the fixed block 13 and is fixedly connected to the bearing bracket by a fixed connecting rod and is set away from components such as the hollow block 15 and the damping spring rod 16. When the edge of the steel plate is concave or convex or arc-shaped, the roller 17 first contacts the edge and compresses the damping spring rod 16. The fixed connecting rod drives the grinding equipment body 14 to generate synchronous displacement, thereby adapting to the change of edge contour. For example, when the edge of the steel plate is wavy, the roller 17 will float radially along the top plate 11 with the wave, driving the grinding equipment body 14 to keep in contact. During this period, the damping spring rod 16 is used to drive the roller 17 to fit against the side wall of the steel plate or absorb displacement.

[0034] The straight scissor lift 18 is set at the top of the hollow block 15 and the roller 17. Each node at the top of the scissor lift is rotatably equipped with a pulley 2. The belt 2 is wrapped around the outside of all the pulley 2. When the motor drives the pulley 21 to rotate, the pulley 21 drives the pulley group 19 to rotate through the fixed shaft, which in turn drives the roller 17 to rotate. The outer wall of the roller 17 is made of rubber. The extension direction of the straight scissor lift 18 is consistent with the radial direction of the top plate 11. It is mainly used to maintain the tension of the pulley 2 and belt 2 when the roller 17 retracts from the outer edge of the steel plate.

[0035] The grinding equipment body 14 is a known existing technology. The basic function required here is to adjust the angle and distance of the grinding head. That is, the above parameters are preset according to the grinding requirements. After locking, the steel plate is rotated as the roller 17 in the limiting mechanism rotates. When grinding steel plates with irregular edges, the grinding head of the grinding equipment body 14 can always track the edge of the steel plate without manual adjustment.

[0036] Please see the appendix Figure 1 To be continued Figure 5 The present invention provides a technical solution: multiple sliding channels II are provided on the inner wall of the bottom of the cylinder 10, which are arranged in a ring array about the axial direction of the cylinder 10 and extend radially along the cylinder 10. A horizontally arranged electric push rod is embedded in one of the sliding channels II. The telescopic end of the electric push rod is set towards the axis of the cylinder 10. A limit block is fixed to the telescopic end of the electric push rod. The limit block is rotatably set at the position of the pulley 21 at the bottom of the annular scissor frame 20 corresponding to the outer edge. The limit block slides in the sliding channel II.

[0037] The cross-section of the slider 30 along the horizontal direction is rhomboid and one of its diagonals is aligned with the radial direction of the top plate 11. The sliding channel 1 has a storage groove on the inner side wall along the circumference of the top plate 11. The sealing mechanism includes multiple sliders 31 that are slidably disposed in the storage groove.

[0038] The horizontal cross section of the second slider 31 is a right trapezoid, and the inclined surface is set towards the inner wall of the storage groove along the circumference of the top plate 11. An elastic metal sheet is fixed at one end of the second slider 31 near the inner wall of the storage groove. Two adjacent second sliders 31 not located on the same side of the sliding channel are radially staggered about the top plate 11. The first slider 30 slides against the second slider 31.

[0039] The slider 2 31 has a placement channel that runs radially through the top plate 11 at the corner end near the center of the sliding channel 1. The slider 1 30 has a horizontal wedge block 32 fixed at both corner ends along the radial direction of the top plate 11. The length direction of the wedge block 32 is consistent with the radial direction of the top plate 11. A wedge block 2 33 is fixed in the placement slot. The ends of the wedge block 32 away from the slider 1 30 are both vertical inclined surfaces along the width direction of the sliding channel 1. The wedge block 1 32 and the wedge block 2 33 slide and abut against each other.

[0040] It should be noted that: slider 2 31 is slidably disposed on the two inner side walls of the top plate 11 along the circumference of the sliding channel 1. Multiple sliders 2 31 are staggered and abutted in the sliding channel 1 along the length of the sliding channel 1, and slide and abut against each other with slider 1 30. The horizontal cross section of slider 2 31 is a right trapezoid, and the inclined surface is set towards the inner wall of the sliding channel 1. Multiple sliders 2 31 are staggered to form a zipper-like structure to seal the sliding channel 1.

[0041] The storage channel is located at the corner of slider 2 31 away from the inner wall of sliding channel 1, and its vertical height is slightly greater than that of wedge block 1 32, so as to ensure that slider 1 30 can smoothly push slider 2 31 open during the sliding process.

[0042] The elastic metal sheet is fixed to the inner side wall of the slider 2 31 near the sliding channel 1 along the circumference of the top plate 11, and the end away from the slider 2 31 is fixed to the inner side wall of the sliding channel 1. The elastic metal sheet can ensure that the slider 2 31 always maintains a sealed state when it is not subjected to external force, preventing welding slag and small parts from falling into the top plate 11. After the slider 1 30 moves and pushes the slider 2 31 open, it can be reset to continue sealing.

[0043] Working principle:

[0044] First, place the steel plate on the rotating table 12, start the electric push rod, and its telescopic end drives the limit block to move in the sliding channel 2, pushing the annular scissor frame 20 to extend or retract, so that the pulley 21 moves synchronously and keeps the belt 22 taut, and then drives the fixed block 13 to be radially positioned through the slider 30, so that the grinding equipment body 14 is close to the edge of the steel plate.

[0045] The drive motor drives pulley 21 to rotate, which in turn causes pulley group 19 to rotate via a fixed shaft. This drives roller 17 to rotate and assists the steel plate in rotating. When the edge of the steel plate is uneven, roller 17 contacts the edge and compresses damping spring rod 16. Through a fixed connecting rod, the grinding equipment body 14 is driven to move synchronously to adapt to the contour changes.

[0046] When slider 1 30 moves within sliding channel 1, its wedge block 1 32 abuts against the wedge block 2 33 of slider 2 31, pushing slider 2 31 open. The elastic metal sheet resets slider 2 31, achieving dynamic sealing, preventing debris from entering, and finally completing the removal of burrs from the edge of the steel plate.
