Description

Technical Field

[0001] This utility model relates to a steel plate processing equipment, and more particularly to a steel plate cross-section grinding mechanism. Background Technology

[0002] Existing steel plate cross-section grinding mechanisms typically use conveyor rollers in conjunction with friction wheels to grind steel plates, that is, to use friction wheels to grind the sides of the steel plates being conveyed.

[0003] For example, Chinese invention patent CN119328522A discloses "a grinding mechanism for the cross-section of an air filter type steel plate", which grinds the burrs on the side of the sheared steel plate by means of a conveying roller, and the generated debris is adsorbed on the air hole, guided into the connecting pipe and collected by the waste collection box.

[0004] This type of steel plate cross-section grinding mechanism has defects. Because the metal surface of the steel plate is relatively smooth, when the steel plate passes through the roller conveyor after pre-processing, there is only constraint on the upper and lower surfaces of the steel plate, but no constraint in the left and right directions. When the steel plate is fed into the conveyor roller, there is an angular offset, which causes the friction wheel and the side of the steel plate to not be on the same plane, affecting the grinding accuracy. In addition, the friction wheel and the steel plate cross-section will overheat after working for a long time, resulting in high wear of the friction wheel and increasing production costs. Utility Model Content

[0005] To overcome the shortcomings of existing steel plate grinding technologies, where the roller conveyor only constrains the upper and lower surfaces during steel plate grinding, resulting in uncontrolled lateral freedom and angular deviations that affect grinding accuracy, and the cost drawbacks of dry grinding (accelerating friction wheel wear after prolonged use, requiring frequent replacements, and causing environmental pollution from metal shavings), this invention provides a steel plate grinding mechanism. This mechanism eliminates deviations through a bidirectional spatial constraint mechanism, suppresses thermal deformation through a closed-loop oil cooling system, and achieves self-recycling of metal shavings to reduce overall costs.

[0007] In the aforementioned steel plate cross-section grinding mechanism, the grinding assembly includes a friction wheel motor suspended on the inner wall of the motor container, with its output shaft passing through the side wall of the motor container and the outer end of the output shaft fixedly connected to a friction wheel. The friction wheel motor drives the friction wheel via AC power. The piston rod end of the third electro-hydraulic rod is fixedly connected to the motor container, and the extension direction of the piston rod of the third electro-hydraulic rod is perpendicular to the direction of movement of the steel plate. There is an outer tube between the third electro-hydraulic rod and the motor container, with one end of the outer tube fixedly connected to the motor container and the other end movably connected to the piston rod of the third electro-hydraulic rod away from the motor container. A spring is installed inside the outer tube, surrounding the piston rod, with one end of the spring fixedly connected to the end of the piston rod and the other end fixedly connected to the inner side of the outer tube away from the motor container. The third electro-hydraulic rod is fixed to a second ear plate, and a motor operation panel is also fixed to the second ear plate. The motor operation panel is directly connected to the friction wheel motor via a wire.

[0008] In the aforementioned steel plate cross-section grinding mechanism, the flexible cleaning brush is movably connected to the third ear plate via an adjusting slot, and the flexible cleaning brush moves along the third ear plate in the vertical direction.

[0009] In the aforementioned steel plate cross-section grinding mechanism, in the settling tank assembly, metal scraps and oil-based lubricant fall into the settling tank body, where the metal scraps are separated by a filter screen; a return oil pipe is fixedly connected to the oil outlet at the lower end of the settling tank body; the return oil pipe is provided with several conical holes spaced apart, and the conical holes are set corresponding to the upper surface of the steel plate; a hydraulic pump is fixedly connected to the return oil pipe, and the oil-based lubricant is pumped by the hydraulic pump through the return oil pipe to the horizontal position directly above the grinding assembly, part of the oil-based lubricant is sprayed onto the friction wheel through the conical holes, and the remaining oil-based lubricant flows back into the settling tank body.

[0010] In the aforementioned steel plate cross-section grinding mechanism, the fixing components can be arranged in multiple sets at intervals along the conveying direction, with the length of each set of horizontal plates matching the maximum processing width of the steel plate; the horizontal plates adopt a segmented extension structure and are fixed to the conveying device bracket through detachable connectors; the side rollers in the fixing components adopt a mirror-symmetrical double roller mechanism, and the piston rod stroke of the second electro-hydraulic rod can be dynamically adjusted.

[0017] The beneficial effects of this invention are that the steel plate cross-section grinding mechanism of this invention adopts a combination of downward pressure rollers and side rollers, effectively eliminating the shortcomings of traditional steel plate cross-section grinding mechanisms that cannot handle different widths, thicknesses, and situations where the steel plates are misaligned. When using an oil-based lubricant with the grinding components, the risk of the friction wheels deforming due to overheating during prolonged operation is effectively reduced. Simultaneously, the return-flow oil supply pipeline continuously sprays the oil-based lubricant onto the grinding components, reducing friction wheel wear, improving grinding efficiency, and lowering processing costs.

[0033] like Figure 1-2 As shown, a steel plate cross-section grinding mechanism includes a conveying device 1, a fixing component 2, a grinding component 3, a surface cleaning brush 4, and a settling tank component 5. The conveying device 1 includes a conveying motor 101, a conveyor belt 102, conveying rollers 103, and a conveying device support 104. A plurality of conveying rollers 103 are rotatably connected to the conveying device support 104, and the conveying rollers 103 are arranged in parallel.

[0034] There are several conveyor rollers 103; and there are belts between adjacent or spaced conveyor rollers 103; the conveyor rollers 103 are connected to the conveyor motor 101 through the conveyor belt 102; the rotation of the conveyor motor 101 drives the conveyor rollers 103 to rotate; at the same time, there are belts between adjacent or spaced conveyor rollers 103; the steel plate moves along the EF direction through the cooperation of the active and driven rollers.

[0035] like Figure 3-4 As shown, the fixing component 2 includes a horizontal plate 201, which is horizontally fixed above the conveying device bracket 104. A first electro-hydraulic rod 202 is vertically mounted on the horizontal plate 201, and its piston rod end is connected to a partition plate 204. A guide post 205 is fixedly mounted at the geometric center of the partition plate 204, and the guide post 205 passes through the horizontal plate 201 vertically through a hole. Several pressing rollers 206 are installed below the partition plate 204, and the first electro-hydraulic rod 202 adjusts the pressing rollers 206 to move vertically.

[0036] The conveying device bracket 104 is fixedly connected to two sides with first ear plates 203. The first ear plates 203 are horizontally fixedly connected to two sides with second electro-hydraulic rods 207. The piston rod ends of the rods are connected to side rollers 208 for adjusting the movement of the side rollers 208 in the horizontal direction. There is an outer tube between the second electro-hydraulic rods 207 and the side rollers 208. One end of the outer tube is fixedly connected to the side rollers 208, and the other end away from the side rollers 208 is movably connected to the piston rod of the second electro-hydraulic rods 207. A spring is installed inside the outer tube and surrounds the piston rod. One end of the spring is fixedly connected to the end of the piston rod, and the other end is fixedly connected to the inner side of the outer tube away from the side rollers 208. When the two symmetrical second electro-hydraulic rods 207 continue to advance towards each other, the spring uses the characteristics of flexible connection to constrain the movement of the side rollers 208, thereby achieving a buffering effect. After the steel plate enters the conveying device 1, the first electro-hydraulic rod 202 drives the lower roller 206 to press the upper surface of the steel plate, and the second electro-hydraulic rod 207 pushes the side roller 208 to clamp the side of the steel plate, which is used to determine the direction of movement of the steel plate and prevent the steel plate from deviating.

[0037] like Figure 5-6As shown, the grinding assembly 3 includes a friction wheel 301, a friction wheel motor 302, a motor housing 303, a third electro-hydraulic rod 304, a motor operation panel 305, and a second lug 306. The friction wheel motor 302 is suspended on the inner wall of the motor housing 303, with its output shaft passing through the side wall of the motor housing 303. The outer end of the output shaft is fixedly connected to the friction wheel 301, completely detaching the working area of ​​the friction wheel 301 from the space of the motor housing 303. The friction wheel motor 302 drives the friction wheel 301 via AC power. The piston rod end of the third electro-hydraulic rod 304 is fixedly connected to the motor housing 303, and the extension direction of the piston rod 304 is perpendicular to the direction of steel plate movement. This is used to adjust the friction wheel's horizontal movement so that it contacts the cross-section of the steel plate. There is an outer tube between the third electro-hydraulic rod 304 and the motor container 303. One end of the outer tube is fixedly connected to the motor container 303, and the other end, away from the motor container 303, is movably connected to the piston rod of the third electro-hydraulic rod 304. A spring is installed inside the outer tube and surrounds the piston rod. One end of the spring is fixedly connected to the end of the piston rod, and the other end is fixedly connected to the inner side of the outer tube away from the motor container 303. When the two symmetrical third electro-hydraulic rods 304 continue to advance towards each other, the spring uses its flexible connection characteristic to constrain the movement of the friction wheel 301, thereby achieving a buffering effect.

[0038] The third electric hydraulic rod 304 is fixed on the second ear plate 306. The second ear plate 306 is also fixed with a motor operation panel 305. The motor operation panel 305 is directly connected to the friction wheel motor 302 through wires and is used to switch the friction wheel motor 302 on and off and regulate its power.

[0039] like Figure 7 As shown, the surface cleaning brush 4 includes a flexible cleaning brush 401, an adjusting slot 402, and a third ear plate 403. The flexible cleaning brush 401 is movably connected to the third ear plate 403 through the adjusting slot 402. The flexible cleaning brush 401 moves vertically along the third ear plate 403 to adapt to the height of the steel plate and rotate to remove metal debris and oil-based lubricant from the upper surface of the steel plate.

[0040] like Figure 8As shown, the settling tank assembly 5 includes a settling tank body 501, a filter screen 502, a return oil pipe 503, and a hydraulic pump 504. Metal scraps and oil-based lubricant fall into the settling tank body 501. The filter screen 502 separates the metal scraps. The oil outlet at the lower end of the settling tank body 501 is fixedly connected to the return oil pipe 503. The return oil pipe 503 has several tapered holes spaced apart, and the tapered holes are set corresponding to the upper surface of the steel plate for uniformly spraying oil-based lubricant onto the grinding assembly 3. The hydraulic pump 504 is fixedly connected to the return oil pipe 503. The oil-based lubricant is pumped by the hydraulic pump 504 through the return oil pipe 503 to a position directly above the grinding assembly 3. Part of the oil-based lubricant is sprayed onto the friction wheel 301 through the tapered holes for lubrication and cooling. The remaining oil-based lubricant flows back to the settling tank body 501 to ensure the recycling of the oil-based lubricant.

[0041] To enhance adaptability to steel plates of different specifications, the fixing assembly 2 adopts a space-expandable design: multiple sets of fixing assemblies 2 are arranged at intervals along the conveying direction; the length of each set of horizontal plates 201 matches the maximum processing width of the steel plate. The horizontal plates 201 adopt a segmented extension structure and are fixed to the conveying device bracket 104 through detachable connectors, enabling flexible adjustment of the coverage area. The side rollers 208 in the fixing assembly 2 adopt a mirror-symmetrical double roller mechanism, and the piston rod stroke of the second electro-hydraulic rod 207 can be dynamically adjusted. Multiple sets of fixing assemblies 2 form a continuous constraint force, eliminating positional offset during long-distance conveying; the symmetrical roller mechanism adapts to changes in the width of the steel plate, avoiding single-point stress concentration.

[0042] The surfaces of the pressure roller 206 and the side roller 208 are composite elastic buffer layers, and the outer edge of the buffer layer is provided with anti-slip texture to enhance the constraint stability of the steel plate.

[0043] The motor housing 303 is made of copper, which has better thermal conductivity than iron. This allows the heat generated by the friction wheel motor 302 during operation to be conducted to the air more quickly, preventing the friction wheel motor 302 from overheating and short-circuiting due to prolonged operation.

[0044] The 401 flexible cleaning brush is made of oleophobic synthetic fibers, allowing debris to fall off naturally under gravity, reducing the frequency of manual cleaning. The quick-release design enables in-situ maintenance, shortening equipment downtime; the oleophobic material and rotating design work together to inhibit debris adhesion.

[0045] To address the flow control requirements of oil-based lubricants, the oil circuit system of the settling tank component 5 is structurally optimized: the return oil pipe 503 has a tapered section after passing through the spray area. The change in cross-sectional area increases the fluid velocity as it flows through the tapered section, creating a local negative pressure zone in the diffusion section behind the tapered section. This naturally slows down the oil flow rate and stabilizes the output pressure. The hydraulic pump 504 is linked to the negative pressure zone, automatically compensating for flow rate fluctuations when fluctuations in the oil-based lubricant flow rate are detected, maintaining spray uniformity. Pipe diameter changes enable fluid self-regulation, reducing reliance on external control components; the negative pressure effect ensures a continuous and stable coverage of the polishing area with the oil-based lubricant.

[0046] The filter 502 uses a multi-layered, staggered arrangement to intercept metal debris while preventing blockage of the flow channels.

[0047] The hydraulic pump 504 can use an axial piston variable pump of model "HP6V" and an electronic pump controller of model "HLEC2414-PQP-PN" to dynamically match its output power with the speed of the friction wheel motor 302. When the speed of the friction wheel 301 increases, the oil injection flow rate increases synchronously.

[0048] When this utility model is in operation, the conveyor motor 101 is started, which drives the conveyor belt 102 to rotate. The conveyor belt 102 drives the conveyor rollers 103 to rotate. There are belts between several adjacent or spaced conveyor rollers 103. Through the cooperation of the active and driven rollers, the steel plate moves along the EF direction. When the steel plate moves to the fixing component 2, the second electro-hydraulic rod 207 drives the side rollers 208 to clamp the two sides of the steel plate. After clamping the two sides of the steel plate, the first electro-hydraulic rod 202 drives the pressing rollers 206 to press the upper surface of the steel plate, thereby fixing the position of the steel plate under different widths, different thicknesses, and steel plate position offsets. When the steel plate moves to the grinding component 3, the friction wheel motor 302 is started, driving the friction wheel 301 to rotate. The third electro-hydraulic rod 307 drives the grinding component 208 to rotate. 04. During operation, the friction wheel 301 is driven to press against the cross-section of the steel plate, grinding the cross-section. Oil-based lubricant is simultaneously sprayed onto the friction wheel 301, providing lubrication and cooling effects, reducing friction wheel wear, and improving grinding efficiency. When the steel plate moves to the surface cleaning brush 4, the flexible cleaning brush 401 moves vertically through the adjusting slot 402, pressing it against the upper surface of the steel plate to remove metal debris and oil-based lubricant. The metal debris and oil-based lubricant fall into the settling tank assembly 5. After a period of settling and filtration, the metal debris remains on the filter screen 502, while the oil-based lubricant is pumped through the return oil pipe 503 and the hydraulic pump 504 to the top of the grinding assembly 2 for spraying, realizing the recycling of the oil-based lubricant. The cleaned steel plate is then sent out from the output port.
