Description

Technical Field

[0001] This invention belongs to the field of metal deburring technology, specifically relating to an edge deburring device for steel plate processing. Background Technology

[0002] During steel plate cutting, stamping, or laser processing, burrs and sharp angles at the edges are unavoidable process defects. These burrs not only affect the assembly accuracy and safe operation of the workpiece, but may also cause subsequent paint peeling, personnel injuries, and other hazards. Therefore, deburring the edges of steel plates has become a critical process in metal processing.

[0003] Currently, the main technical solutions for edge burr removal on straight-edged steel plates are as follows: 1. Manual grinding: The operator uses a handheld angle grinder or file to grind the edge of the steel plate. This method is highly flexible, but labor-intensive, inefficient, and difficult to guarantee consistency in large-scale processing; the grinding force and angle depend on the operator's experience, which can easily lead to uneven edges or excessive wear; high-speed rotating tools pose safety hazards and threaten the operator's health; 2. Using a motor-driven fixed grinding wheel, with the steel plate manually pushed for edge grinding, although this reduces equipment costs, the frictional resistance during the steel plate's movement is high, which can easily lead to surface scratches or vibrations, affecting the straightness of the edge.

[0004] For deburring straight edges of small and medium-sized steel plates, the market urgently needs a solution that balances ease of operation, processing consistency, and safety. Existing equipment either relies on high-cost automation or sacrifices accuracy and safety, especially in terms of angular stability and human-machine interaction safety in manual feeding mode, where there are significant technological gaps.

[0006] As a preferred embodiment of the present invention, the grinding area faces the working seam, and the grinding area and the operating table are arranged perpendicularly, and the working seam and the grinding area are arranged collinearly.

[0007] As a preferred embodiment of the present invention, the sliding assembly includes a mounting cavity, which is evenly arranged in a rectangular array on the worktable surface. A ball bearing is installed inside the mounting cavity, and the diameter of the ball bearing is larger than the diameter of the opening of the mounting cavity.

[0008] As a preferred embodiment of the present invention, the drive roller assembly includes a drive motor, the output end of the drive motor is connected to a rotating shaft, the shaft body of the rotating shaft is fixed with a drive roller body, and the shaft end of the rotating shaft is rotatably connected by a bearing and a bracket.

[0009] As a preferred embodiment of the present invention, a door panel is hinged to the back of the housing, the dust collection mechanism is installed at the bottom of the door panel, the dust collection mechanism includes a centrifugal fan, an air duct is fixed to the air inlet of the centrifugal fan, the air inlet of the air duct is fixed to the door panel, and a detachable filter is installed at the air outlet of the centrifugal fan.

[0010] As a preferred embodiment of the present invention, one end of the tension adjusting rod is rotatably connected to the top of the bracket, and the other end of the tension adjusting rod is equipped with a first electric cylinder. The tail end of the first electric cylinder body is rotatably connected to the inner side of the bracket, and the output end of the first electric cylinder is rotatably connected to the end of the tension adjusting rod.

[0011] As a preferred embodiment of the present invention, the limiting component includes a mounting plate, which is fixed to a bracket. A slide is slidably connected to the top of the mounting plate. A second electric cylinder is fixed to one end of the mounting plate. The output end of the second electric cylinder is fixedly connected to the slide. A central shaft is fixed at the center of the bottom of the slide. A bushing is rotatably connected to the central shaft.

[0012] As a preferred embodiment of the present invention, a transparent observation window is provided on the top of the side of the housing connected to the operating table, and a collection box is slidably connected to the bottom of the housing via a slide rail.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The automated grinding mode of driving the annular grinding belt with the drive roller group replaces the traditional manual hand-held grinding machine operation, which significantly reduces labor intensity. At the same time, the steel plate edge can be accurately put into the grinding area by manual pushing. No professional training is required to complete the operation, which further reduces the dependence on operating experience and ensures that different operators can work stably. The annular grinding belt forms a cyclic motion under the drive roller group. In conjunction with the grinding area formed by the first driven roller, the contact angle design between the grinding belt and the edge of the steel plate is used to realize the deburring and chamfering processing in a single feed, which significantly improves efficiency compared with the traditional step-by-step operation.

[0015] (2) The enclosed structure of the casing, combined with the directional design of the working seam, isolates the high-speed grinding components from the operator. The combination of the tension adjustment rod and the first electric cylinder can adjust the tension of the annular grinding belt in real time to ensure stable grinding pressure for steel plates of different thicknesses. At the same time, the contact pressure and angle between the steel plate and the grinding belt are controlled by the rigid limiting component to avoid uneven edge caused by manual operation, achieve consistency in mass processing, adapt to edge processing of steel plates of various specifications, and improve the versatility of the equipment.

[0016] (3) The collinear design of the grinding area and the working seam and the layout perpendicular to the operating table ensure that the advancing angle of the steel plate edge and the annular grinding belt is constant, avoiding edge straightness error caused by angle deviation and solving the shaking problem in the traditional equipment during the advancement process; the ball bearing design on the surface of the operating table transforms the sliding friction between the steel plate and the table into rolling friction, greatly reducing the advancing resistance, which not only avoids scratches on the steel plate surface, but also makes manual advancement smoother and less strenuous.

[0017] (4) The integrated dust collection mechanism forms a directional airflow through a centrifugal fan and air duct, which efficiently captures the metal dust generated during grinding. The dust is collected in a centralized manner through a detachable filter and a collection box is used to collect solid debris, which significantly improves the working environment and reduces the harm of dust to the health of operators. The transparent observation window enables visual monitoring while ensuring the safety of human-machine interaction and solves the safety hazards of traditional open equipment.

[0018] In summary, this invention combines a simplified basic structure with ease of operation, enabling the equipment to be highly adaptable to small and medium-sized steel plate straight edge processing scenarios, and meeting the needs of mass production without the need for high automation investment.

[0036] Please see Figure 2In order to collect the metal dust generated during the grinding process in a timely manner, prevent the dust from spreading through filtration, improve the working environment and protect the health of operators, in this embodiment, as a preferred technical solution of the present invention, a door panel 17 is hinged to the back of the casing 1, and a dust collection mechanism is installed at the bottom of the door panel 17.

[0037] Please see Figure 4-6 In order to achieve flexible adjustment of the tension of the annular grinding belt 11, ensure that the grinding belt maintains a suitable tension during operation, and ensure uniform and stable grinding pressure, in this embodiment, as a preferred technical solution of the present invention, one end of the tension adjusting rod 9 is rotatably connected to the top of the bracket 5, and the other end of the tension adjusting rod 9 is equipped with a first electric cylinder 21. The tail end of the first electric cylinder 21 is rotatably connected to the inner side of the bracket 5, and the output end of the first electric cylinder 21 is rotatably connected to the end of the tension adjusting rod 9.

[0038] Please see Figure 4-7 In order to accurately limit the steel plate, and at the same time control the contact pressure and angle between the steel plate and the grinding belt to adapt to the grinding needs of steel plates of different thicknesses, in this embodiment, as a preferred technical solution of the present invention, the limiting component includes a mounting plate 22, which is fixed on the bracket 5. A slide table 23 is slidably connected to the top of the mounting plate 22. A second electric cylinder 27 is fixed to one end of the mounting plate 22. The output end of the second electric cylinder 27 is fixedly connected to the slide table 23. A central shaft 24 is fixed at the center of the bottom of the slide table 23. A bushing 25 is rotatably connected to the shaft of the central shaft 24.

[0039] Please see Figure 1 In order to facilitate operators to observe the internal grinding situation in real time, and to facilitate the collection and cleaning of grinding debris, thereby improving the ease of operation, in this embodiment, as a preferred technical solution of the present invention, a transparent observation window 26 is provided on the top of the side of the housing 1 connected to the operating table 2, and a collection box 28 is slidably connected to the bottom of the housing 1 via a slide rail.

[0040] In summary, based on the above technical solutions, the detailed workflow of this edge deburring device for steel plate processing is as follows:

[0041] Please see Figure 1 and Figure 3 Workpiece placement and positioning: The steel plate to be processed is placed stably on the surface of the operating table 2. The sliding assembly consists of a mounting cavity 12 opened on the table surface of the operating table 2 and a ball bearing 13 installed inside. The ball bearing 13 protrudes from the opening of the mounting cavity 12. When the steel plate is pushed, the ball bearing 13 rotates freely in the mounting cavity 12, which greatly reduces the frictional resistance between the steel plate and the operating table 2, making it easy for the operator to move the steel plate.

[0042] Please see Figure 4 and Figure 7 After the edge of the steel plate is aligned with the working seam 3, the limiting component is activated for positioning. The mounting plate 22 of the limiting component is fixed on the bracket 5. The top of the mounting plate 22 is provided with a sliding groove. The slide table 23 is slidably connected to the mounting plate 22 through the sliding groove. The second electric cylinder 27 is fixed at one end of the mounting plate 22. Its output end is connected to the slide table 23. When the second electric cylinder 27 is activated, the piston rod extends and retracts, driving the slide table 23 to move back and forth along the sliding groove, thereby adjusting the front and back position of the bushing 25. The bushing 25 is rotatably connected to the central shaft 24 at the bottom center of the slide table 23. The bushing 25 moves with the slide table 23 to form a hard contact with the edge of the steel plate. This hard contact not only forms a lateral limit on the steel plate, but also ensures that the contact pressure between the steel plate and the annular grinding belt 11 reaches the preset value each time through the resistance feedback and limitation generated by the contact. Since the bushing 25 can rotate around the central shaft 24, it can rotate synchronously with the steel plate as it moves along the operating table 2, which not only maintains a stable hard contact state, but also avoids scratching the edge surface of the steel plate after grinding.

[0043] Please see Figure 4 and Figure 6 Grinding operation: Start the drive roller group. The output end of the drive motor 14 is connected to the rotating shaft 15 through a coupling. The shaft body of the rotating shaft 15 is fixed with the drive roller body 16. Its shaft end is rotatably connected to the bracket 5 through a bearing. The drive motor 14 drives the rotating shaft 15 and the drive roller body 16 to rotate. The annular grinding belt 11 is sleeved on the outside of the drive roller group, the first driven roller 7 and the second driven roller 10, and forms a cyclic motion under the drive of the drive roller body 16.

[0044] Please see Figure 4-6 Each of the two supports 5 has a support 6 fixed at its front end. The top and bottom of the symmetrical supports 6 are respectively rotatably connected to the first driven rollers 7. The two first driven rollers 7 form a grinding area 8 (i.e., the steel plate edge insertion area). The tension adjusting rods 9 installed at the top of the two supports 5 are rotatably connected to the second driven rollers 10. One end of the tension adjusting rod 9 is rotatably connected to the top of the support 5, and the other end is rotatably connected to the output end of the first electric cylinder 21. The tail end of the cylinder body of the first electric cylinder 21 is rotatably connected to the inner side of the support 5. By controlling the extension and retraction of the piston rod of the first electric cylinder 21, the tension adjusting rod 9 can be pushed or pulled to rotate around the connection point with the support 5, thereby adjusting the up and down position of the second driven roller 10, realizing the adjustment of the tension of the annular grinding belt 11, and ensuring that the pressure during grinding is uniform and stable.

[0045] The edge of the steel plate enters the machine housing 1 through the working seam 3 and extends horizontally into the grinding area 8 along the plane of the operating table 2. At this time, the annular grinding belt 11 is in a taut state perpendicular to the operating table 2 under the support of the two first driven rollers 7. When the edge of the steel plate abuts against the middle of the annular grinding belt 11, the grinding belt deforms under the thrust of the steel plate, forming a bend that is concave into the machine housing 1. Please refer to [link / reference]. Figure 9 .

[0046] During the cyclic transmission of the annular grinding belt 11, the two sides of the bend formed by the annular grinding belt 11 make precise contact with the edge of the steel plate: the inner side is in contact with the burr protrusions on the edge of the steel plate, and the sharp burrs are removed by high-speed friction; the outer side is in contact with the upper and lower edges of the edge of the steel plate, and the edges are beveled during continuous transmission to form a chamfer at a preset angle. Because the first electric cylinder 21 maintains a constant tension of the annular grinding belt 11 through the tension adjusting rod 9, and the second electric cylinder 27 of the limiting component adjusts the front and rear limits of the bushing 25, the bend shape of the annular grinding belt 11 is kept stable, so that the contact pressure between the annular grinding belt 11 and the edge of the steel plate is uniform. At the same time, the operator manually pushes the steel plate along the operating table 2 to form relative motion with the cyclic transmission of the annular grinding belt 11, ensuring that the burrs on the entire edge of the steel plate are completely removed, and the chamfered surface is smooth and continuous, avoiding local over-grinding or missed processing.

[0047] Please see Figure 2 Dust collection and filtration: The dust collection mechanism is installed at the bottom of the door panel 17 on the back of the casing 1, and consists of a centrifugal fan 18, an air duct 19, and a removable filter 20. The air inlet of the centrifugal fan 18 is connected to the air duct 19, the air inlet of the air duct 19 is fixed on the door panel 17, and the air outlet of the centrifugal fan 18 is connected to the removable filter 20. During the grinding operation, the centrifugal fan 18 is started, and the metal dust inside the casing 1 is drawn into the centrifugal fan 18 through the air duct 19 under the action of airflow, and then enters the removable filter 20.

[0048] The detachable filter 20 has a hollowed-out outer shell made of ABS engineering plastic. The side air inlet is connected to the air outlet of the centrifugal fan 18 by a plug-in connection. The air outlet at the hollowed-out part is tightly fitted and fixed with a metal mesh filter layer to ensure that all airflow passes through the filter layer. The centrifugal fan 18 on one side of the filter 20's outer shell is connected by a snap-fit, and a silicone sealing ring is provided at the edge for easy removal. After the dust-laden airflow enters the filter 20, large dust particles are intercepted by the metal mesh, and the filtered air is discharged from the hollowed-out part.

[0049] Please see Figure 1Monitoring and storage: A transparent observation window 26, made of tempered glass, is provided on the top of the side of the machine housing 1 connected to the operating table 2. It is surrounded by rubber sealing gaskets and is fixed to the machine housing 1 with bolts. The operator can monitor the internal grinding situation in real time through the transparent observation window 26. A collection box 28 is slidably connected to the bottom of the machine housing 1 through a slide groove. Larger debris generated during the grinding process falls directly into the collection box 28. After the operation is completed, the collection box 28 can be pulled out along the slide rail for cleaning.
