[0015] As described in the background art, a deburring and trimming device for metal mold processing can only remove burrs from the upper end face of the sheet metal. If it is necessary to remove burrs from the lower end face of the sheet metal, the sheet metal must be flipped over and then sent to the grinding mechanism for grinding. The deburring efficiency of the sheet metal needs to be further improved.

[0016] To solve this technical problem, this utility model provides a metal deburring device, which is applied to the deburring treatment of metal sheets.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] Example 1 Please refer to Figure 1-5 A metal deburring device includes: a base frame 1, a conveying and grinding mechanism mounted on the base frame 1, mounting frames 2 mounted on both sides of the base frame 1, and an upper surface grinding mechanism mounted on the mounting frames 2. The conveying and grinding mechanism includes a support frame 3, two rotating rollers 4 rotatably mounted on the support frame 3, a conveying and grinding belt 5 sleeved on the two rotating rollers 4, and a first driver 6 that provides power for the rotation of one of the rotating rollers 4. The upper surface grinding mechanism includes two mechanical slides 7 mounted on the mounting frames 2, a slide 8 mounted on the mechanical slides 7, an adsorption limiting mechanism mounted on the slide 8, and a grinding mechanism for grinding the upper surface of the metal sheet. The adsorption limiting mechanism is used for adsorption limiting of the metal sheet. An acute angle is formed between the mechanical slides 7 and the top surface of the conveying and grinding belt 5. Furthermore, the first driver 6 includes a motor and a transmission component fixedly mounted on the support frame 3. The output shaft of the motor is connected to the corresponding rotating roller 4 via the transmission component. The transmission component can be a synchronous belt, chain, gear set, etc. The acute angle between the conveying and grinding belt 5 and the mechanical slide 7 is 30-60°. It should be noted that the two mechanical slides 7 are driven by the same motor and are synchronously connected via the transmission component to ensure the smooth movement of the slide 8. By starting the mechanical slide 7, the mechanical slide 7 can drive the slide 8 to move up or down, thereby causing the grinding mechanism to feed towards or away from the upper end face of the metal sheet, so as to adjust the distance between the grinding mechanism and the metal sheet.

[0020] For details, please refer to Figure 4The adsorption limiting mechanism includes a first drive cylinder 9 mounted on the slide 8 and a pneumatic suction cup assembly 10 fixedly mounted on the bottom output end of the first drive cylinder 9; the grinding mechanism includes a frame 11 mounted on the slide 8, multiple guide wheels 12 rotatably mounted on the frame 11, and a grinding strip 13 sleeved on the guide wheels 12. The grinding strip 13 is arranged perpendicularly to the conveying grinding belt 5. A second driver 14 is mounted on the frame 11 to provide power for the rotation of one of the guide wheels 12. Furthermore, there are at least two sets of first drive cylinders 9. The first drive cylinders 9 are provided with extension and retraction kinetic energy by an external pneumatic pump station or hydraulic pump station, and the pneumatic suction cup assembly 10 is provided with adsorption kinetic energy by an external suction negative pressure system; the guide wheels 12 near the bottom of the frame 11 are evenly distributed side by side in the horizontal direction to ensure smooth contact between the grinding strip 13 and the top surface of the metal sheet; the second driver 14 can be a motor.

[0021] For details, please refer to Figure 1 The bottom of the support frame 3 is provided with a receiving plate 21, and the top edge of the receiving plate 21 is provided with a surrounding plate 22; furthermore, the receiving plate 21 and the top surrounding plate 22 form an open collection groove.

[0022] For details, please refer to Figures 1-2 ,as well as Figure 4 and Figure 6 The frame 11 is symmetrically equipped with a push-limiting mechanism on both sides. The push-limiting mechanism includes a second drive cylinder 23 and a push-limiting plate 24 installed at the output end of the second drive cylinder 23.

[0023] Specifically, multiple rollers 25 are rotatably mounted on the push-limit plate 24, and the multiple rollers 25 are arranged in parallel with the conveying direction of the conveying and grinding belt 5.

[0024] In this embodiment, the metal deburring device, when grinding the upper surface of a metal sheet, uses a mechanical slide 7 to drive a carriage 8 downwards to ensure close contact between the grinding strip 13 and the top surface of the metal sheet. When deburring the lower surface of the metal sheet, the metal sheet is conveyed by the grinding belt 5 to below the adsorption limiting mechanism. The mechanical slide 7 drives the carriage 8 upwards until the grinding strip 13 disengages from the top surface of the metal sheet. Subsequently, the output end of the first drive cylinder 9 extends, and the pneumatic suction cup assembly 10 moves downwards to contact the top of the metal sheet, adsorbing the metal sheet. The limit is set, while the conveyor grinding belt 5 continuously performs deburring and grinding on the bottom of the metal sheet; the grinding strip 13 is perpendicular to the conveyor grinding belt 5, so that the metal sheet bears friction in different directions, which can prevent relative sliding between the metal sheet and the conveyor grinding belt 5 during the top surface grinding and deburring process, so as to ensure the smooth progress of the top surface deburring and grinding operation of the metal sheet; the receiving plate 21 can receive the debris generated during the grinding process, while the surrounding plate 22 can effectively reduce the metal debris from sliding off the receiving plate 21, and concentrate the metal debris generated during grinding, so as to improve the convenience of subsequent metal debris cleaning. By activating the second drive cylinder 23, the output end of the second drive cylinder 23 extends, causing the push limiting plate 24 to limit the two sides of the metal sheet to prevent the metal sheet from sliding off the conveyor grinding belt 5 during the deburring and grinding of the top surface. The roller 25 can reduce the friction between the push limiting plate 24 and the edge of the metal sheet, avoiding interference with the synchronous movement of the metal sheet following the conveyor grinding belt 5.

[0025] Example 2 For details, please refer to Figures 1-5 It also includes a lifting frame 15 that slides vertically on the base frame 1 and a synchronous lifting drive that provides power for the vertical sliding of the lifting frame 15. The support frame 3 is installed on the lifting frame 15. The synchronous lifting drive includes four sets of screw jacks 16 installed on the base frame 1 and a third drive 17 that provides power for the four sets of screw jacks 16. Further, the third drive 17 preferably consists of a motor, a transmission gearbox, and a synchronous shaft. The output shaft of the motor provides lifting power to the four sets of screw jacks 16 through the transmission gearbox and the synchronous shaft. Alternatively, the third drive 17 can also consist of a motor, a chain, and a sprocket. The output shaft of the motor provides lifting power to the four sets of screw jacks 16 through the chain and the sprocket. The four sets of screw jacks 16 are arranged in a rectangular or square shape at the base frame 1. A sliding rod is installed at the bottom of the lifting frame 15. The base frame 1 has sliding holes that fit the sliding rod. The sliding rod is installed in the sliding holes to further improve the stability of the vertical sliding of the lifting frame 15.

[0026] For details, please refer to Figure 4The bottom of the support frame 3 is equipped with multiple guide rods 18. The lifting frame 15 is provided with a guide cylinder 19 that fits with the outer wall of the guide rods 18. The guide rods 18 are slidably installed in the guide cylinder 19. A spring 20 is sleeved on the guide rods 18. One end of the spring 20 abuts against the top of the lifting frame 15, and the other end of the spring 20 abuts against the bottom of the support frame 3.

[0027] The metal deburring device provided in this embodiment can adjust the height of the support frame 3 when deburring metal sheets of different thicknesses is required. This allows for the adjustment of the distance between the conveyor grinding belt 5 and the grinding strip 13, thereby meeting the deburring requirements of metal sheets of different thicknesses and improving the applicability of the device. Under the action of the guide rod 18, guide cylinder 19 and spring 20, the metal sheet can be flexibly contacted with the conveyor grinding belt 5 or grinding strip 13 during the deburring and grinding operation, avoiding excessive wear on the end face of the metal sheet during the deburring operation.

[0028] The metal deburring device provided by this utility model is used as follows: A metal sheet is placed on the conveyor grinding belt 5, with both ends of the metal sheet positioned between the two push-limiting plates 24. Both ends of the metal sheet are in contact with the rollers 25. The first driver 6 drives the rotating roller 4 to rotate, and the conveyor grinding belt 5 transports the metal sheet to the bottom of the grinding mechanism. The mechanical slide table 7 drives the slide 8 downwards until the grinding belt 13 is in close contact with the upper surface of the metal sheet. The second driver 14 drives the guide wheel 12 to rotate, and the grinding belt 13 grinds the upper surface of the metal sheet passing below. When… When the lower end face of the metal sheet needs to be deburred and polished, the metal sheet is conveyed by the conveying and polishing belt 5 to the area below the adsorption and limiting mechanism. The mechanical slide table 7 drives the slide 8 to move upward until the polishing belt 13 disengages from the top surface of the metal sheet. Then, the output end of the first drive cylinder 9 extends, and the pneumatic suction cup assembly 10 moves downward and contacts the top of the metal sheet. The pneumatic suction cup assembly 10 adsorbs and limits the metal sheet, while the conveying and polishing belt 5 continues to deburr and polish the bottom of the metal sheet. After the deburring of the upper and lower end faces of the metal sheet is completed, the metal sheet can be unloaded.
