Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, specifically to a burr-removing device for steel plate processing. Background Technology

[0002] Grinding is a type of surface modification technology. It generally refers to a processing method that uses rough objects (such as sandpaper containing high-hardness particles) to change the physical properties of the material surface through friction. Its main purpose is to obtain a specific surface roughness. When processing steel, it is necessary to cut it, but the cut plane and edges are prone to burrs and rough surfaces, so the steel plate needs to be deburred.

[0003] For example, Chinese Patent (CN222711699U) discloses a burr-removing device for steel plate processing, including a main body. A threaded block is overlapped on the inner wall of the main body. A rotating component is provided on the right side of the main body. An L-shaped frame is fixedly installed on the top of the threaded block. A slider is fixedly installed at the bottom of the L-shaped frame, and the surface of the slider overlaps with the inner wall of the main body. A limit rod is slidably installed inside the slider, and both ends of the limit rod are fixedly connected to the inner wall of the main body. This burr-removing device for steel plate processing can drive the threaded block to move left or right through the rotating component, so that the threaded block drives the L-shaped frame to move left or right, which is convenient for quickly fixing according to the size of the steel plate. The collecting component collects iron filings and smoke in the collecting hood, preventing iron filings and smoke from splashing and spreading during the burr-removing process of steel plates, thus preventing pollution of the working environment and ensuring the health of the workers.

[0004] The aforementioned device can only grind one point at a time when grinding steel plates. When grinding other areas is required, the steel plate needs to be re-clamped. Frequent re-clamping and single-point grinding result in a slow work pace, significantly reduced production efficiency, and the grinding process cannot be streamlined. Workers need to repeat the three steps of loading, grinding, and unloading. The repetitive clamping operation wastes a lot of time and reduces overall productivity. To address the above problems, a burr grinding device for steel plate processing is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a burr grinding device for steel plate processing. It solves the problem that the current method of grinding steel plates can only grind one point at a time. When grinding other positions is required, the steel plate needs to be re-clamped. Frequent re-clamping and single-point grinding result in a slow work pace, significantly reduced production efficiency, and the inability to form a streamlined operation. Workers need to repeat the three steps of loading, grinding and unloading. The repetitive clamping operation wastes a lot of time and reduces the overall production capacity.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a burr grinding device for steel plate processing, comprising a base plate, a roller conveyor for transporting steel plates is fixedly installed in the middle of the upper surface of the base plate, two guide rods are fixedly connected to the left and right sides of the roller conveyor on the upper surface of the base plate, a fixed plate is fixedly connected above the four guide rods, a grinding assembly is arranged between the four guide rods and below the fixed plate, threaded rods are rotatably connected to the middle of the left and right sides of the bottom surface of the fixed plate, the upper ends of the two threaded rods pass through the bottom surface of the fixed plate and are fixedly connected to the first synchronous pulleys, the two first synchronous pulleys are connected by synchronous belt drive, and a fixed clamp is detachably connected to the outer surface of at least one guide rod, and a limit sensor is fixedly installed on the fixed clamp.

[0010] Preferably, a movable slide rail is fixedly connected to the middle of the inner side of each of the two connecting plates, and a sliding plate is slidably connected to the sides of each of the two sets of movable slide rails via a sliding block. A tension roller is rotatably connected between the two sliding plates, and an electric push rod for pushing the sliding plate is fixedly connected to the inner side of each of the two connecting plates.

[0013] Compared with the prior art, the advantages of this utility model are: 1.

The grinding belt surrounds the pressure detection roller, rotating roller, and tension roller to form a large grinding surface, which can simultaneously treat burrs on the surface and edges of the steel plate without multiple positioning. The tension roller pushes the sliding plate along the moving slide rail through an electric push rod, which can adjust the tension of the grinding belt to ensure that the belt tension is consistent during the grinding process and avoid slippage that affects the grinding effect. The cooling air knife is connected to the air source through a connecting pipe, which can blow cold air into the grinding area to reduce the high temperature generated by grinding in time, prevent the steel plate from deforming due to overheating, and reduce the wear of the grinding belt, thus extending its service life.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Reference Figures 1-6 As shown, a burr-removing device for steel plate processing includes a base plate 1. A roller conveyor 11 for transporting steel plates is fixedly installed in the middle of the upper surface of the base plate 1. The rollers on the roller conveyor 11 are made of a material with high friction to ensure that the steel plates do not slip during transportation and grinding. Two guide rods 2 are fixedly connected to both sides of the roller conveyor 11 on the upper surface of the base plate 1. A fixing plate 3 is fixedly connected above the four guide rods 2. A grinding component 8 is arranged between the four guide rods 2 and below the fixing plate 3. The guide rods 2 are the grinding component 8. The up-and-down movement provides guidance and ensures the stability of the movement. Threaded rods 4 are rotatably connected to the middle of the left and right sides of the bottom surface of the fixed plate 3. The upper ends of the two threaded rods 4 pass through the bottom surface of the fixed plate 3 and are fixedly connected to the first synchronous pulleys 5. The two first synchronous pulleys 5 are connected by a synchronous belt drive. At least one guide rod 2 has a fixed clamp 12 detachably connected to its outer surface. Limit sensors 13 are fixedly installed on the fixed clamp 12. The detachable connection of the fixed clamp 12 facilitates position adjustment according to the thickness of the steel plate, thereby ensuring that the grinding assembly 8 is not damaged.

[0020] Specifically, a connecting arm 9 is fixedly connected to the left side of the fixed plate 3, and a controller 10 is fixedly connected to the end of the connecting arm 9. A motor frame 6 is fixedly connected to the right side of the upper surface of the fixed plate 3, and a first motor 7 is fixedly installed above the motor frame 6. The output end of the first motor 7 is fixedly connected to the first synchronous wheel 5 on the right side. The controller 10 is used to receive sensor signals, control the motor operation, and adjust the device parameters. For specific selection, refer to Siemens S7-1200.

[0021] Specifically, the grinding assembly 8 includes a movable plate 801. The four corners of the movable plate 801 are slidably connected to four guide rods 2 through sliding sleeves. The left and right ends of the movable plate 801 are threadedly connected to two threaded rods 4 through threaded sleeves. The grinding assembly 8 is driven to move up and down through the threaded transmission to adjust the distance between the grinding belt 812 and the surface of the steel plate.

[0022] Furthermore, connecting plates 805 are fixedly connected to the bottom left and right sides of the movable plate 801. A pressure detection roller 806 is rotatably connected between the two connecting plates 805 above, and a rotating roller 807 is rotatably connected between the two connecting plates 805 below. The left end of the rotating roller 807 passes through the side of the left connecting plate 805 and is fixedly connected to the second synchronous wheel 813.

[0023] Specifically, a movable slide rail 808 is fixedly connected to the inner center of each of the two connecting plates 805. Sliding plates 809 are slidably connected to the sides of each of the two sets of movable slide rails 808 via sliding blocks. A tension roller 810 is rotatably connected between the two sliding plates 809. An electric push rod 811 for pushing the sliding plates 809 is fixedly connected to the inner side of each of the two connecting plates 805. A grinding belt 812 is connected between the tension roller 810, the pressure detection roller 806, and the rotating roller 807. When the grinding belt 812 contacts the steel plate and applies grinding pressure, the reaction force of the steel plate on the belt is transmitted to the pressure detection roller 806 through the belt, causing the pressure detection roller 806 to experience downward pressure. This pressure acts on the bearing or the sensing component connected to the shaft end of the pressure detection roller 806, thereby ensuring uniform grinding force and pressure. The detection roller 806 integrates a pressure sensor (such as a strain gauge sensor or a piezoelectric sensor). Its sensing element is connected to the force-bearing part of the roller. When the pressure detection roller 806 is subjected to pressure transmitted by the sanding belt, the sensing element will undergo physical deformation (such as changes in the resistance of the strain gauge or changes in the charge of the piezoelectric material), and convert this deformation into an electrical signal. The electrical signal generated by the pressure sensor is transmitted to the controller 10 through wires. The controller 10 analyzes and processes the signal and calculates the current pressure value of the sanding belt on the steel plate in real time. If the pressure value exceeds or falls below a preset threshold, the controller 10 will automatically trigger an adjustment mechanism (such as controlling the first motor 7 to drive the threaded rod 4 to rotate, adjusting the height of the moving plate 801, and changing the distance between the grinding component 8 and the steel plate), thereby dynamically adjusting the pressure to a suitable range to ensure a uniform and stable grinding effect.

[0024] Specifically, a second motor 814 is fixedly connected to the left side of the upper surface of the movable plate 801. A third synchronous pulley 815 is fixedly connected to the output end of the second motor 814. The third synchronous pulley 815 and the second synchronous pulley 813 are connected by a synchronous belt drive, which provides power for the rotation of the rotating roller 807 and the grinding belt 812.

[0025] Specifically, baffles 804 are fixedly connected to the bottom left and right sides of the movable plate 801 between the connecting plate 805 and the guide rod 2. A cooling air knife 802 is fixedly connected to the bottom front side of the movable plate 801. The top of the cooling air knife 802 passes through the bottom surface of the movable plate 801 and is fixedly connected to a connecting pipe 803. Compressed air is introduced through the connecting pipe 803 to the external air source and spray cold air into the grinding area to reduce the temperature of the sanding belt and steel plate and prevent overheating damage.

[0026] Working principle: First, connect the external air source to the connecting pipe 803. Based on the thickness of the steel plate to be ground, set the height of the grinding assembly 8 via the controller 10. Start the first motor 7, whose output drives the right first synchronous pulley 5 to rotate. Through synchronous belt transmission, the left first synchronous pulley 5 rotates synchronously, and the two threaded rods 4 rotate accordingly, driving the moving plate 801 to slide up and down along the guide rod 2 until the distance between the grinding belt 812 and the steel plate surface meets the requirements. Adjust the position of the fixing clamp 12 on the guide rod 2 so that the limit sensor 13 is aligned with the moving plate. The lowest position of the moving plate 801 is used to detect whether the moving plate 801 has reached the lowest position, preventing excessive contact between the grinding belt 812 and the steel plate, which could cause the grinding belt 812 to fail to rotate properly. The electric push rod 811 is activated, pushing the sliding plate 809 to move along the moving slide rail 808, which in turn drives the tension roller 810 to adjust its position, ensuring the grinding belt 812 is tensioned to a suitable level to prevent slippage during grinding. The steel plate to be ground is then placed at the input end of the roller conveyor 11, which starts, moving the steel plate towards the grinding assembly. The steel plate is conveyed below the grinding assembly 8. When the front end of the steel plate passes below the grinding assembly 8, the output end of the second motor 814 drives the third synchronous pulley 815 to rotate. Through synchronous belt transmission, the second synchronous pulley 813 and the rotating roller 807 rotate. The rotating roller 807 drives the grinding belt 812 to circulate. The steel plate is continuously conveyed to the area below the grinding belt 812. The moving grinding belt 812 contacts the surface and edges of the steel plate, removing burrs through friction. The pressure detection roller 806 detects the pressure of the grinding belt on the steel plate in real time and feeds the data back to the controller 10. If the pressure is too high... If the grinding force is too large or too small, the controller 10 adjusts the height of the moving plate 801 through the first motor 7 to ensure uniform grinding force. During the grinding process, the baffle 804 blocks the splashing of iron filings to prevent the threaded rod 4 and the guide rod 2 from being damaged by the splashing iron filings. The cooling air knife 802 introduces compressed air through the connecting pipe 803 and sprays cold air into the grinding area to reduce the temperature of the sanding belt and steel plate and prevent overheating damage. If continuous processing is required, the steel plate to be ground can be continuously placed at the input end of the roller conveyor line 11, and the device can repeat the above process to realize automated assembly line operation.
