Description

Technical Field

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

[0002] In subsequent production processes, cold-rolled steel sheets need to be cut into rectangular plates of the required size. The cut plates are then precision-machined to obtain the desired products or workpieces. After the cold-rolled steel sheets are cut, burrs are generated on their edges. In subsequent processing, to avoid the impact of burrs on the processing and to prevent injury, the four sides of the cut cold-rolled steel sheets need to be deburred and trimmed.

[0003] Existing technology typically uses clamps to fix the cut cold-rolled steel sheet, and then uses a grinding and finishing device to deburr the side edges of the cold-rolled steel sheet. After deburring one side of the cold-rolled steel sheet, the position of the cold-rolled steel sheet needs to be readjusted to continue deburring the next side edge. As a result, the position of the cold-rolled steel sheet needs to be adjusted three times during the deburring process on all four sides. Readjusting the position of the cold-rolled steel sheet requires removing the clamps and reinstalling them, which is time-consuming and labor-intensive, and greatly reduces the efficiency of deburring. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency deburring device for processing cold-rolled steel sheets, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A deburring device for processing cold-rolled steel sheets includes a base, a placement platform for placing cold-rolled steel sheets fixed on the base, grinding mechanisms for grinding and deburring the side edges of the cold-rolled steel sheets arranged on the four sides of the placement platform above the base, an mounting platform arranged above the placement platform via a three-axis moving assembly, a suction cup for holding the cold-rolled steel sheets installed below the mounting platform, and an air distribution mechanism for evacuating or inflating the suction cups on the mounting platform.

[0007] Furthermore, the three-axis moving assembly includes a first moving assembly, a second moving assembly, and a third moving assembly. The first moving assembly is arranged above the placement platform, the second moving assembly is arranged below the first moving assembly, and the third moving assembly is arranged below the second moving assembly. The mounting platform is arranged below the third moving assembly. The first moving assembly is used to drive the mounting platform to move left and right, the second moving assembly is used to drive the mounting platform to move back and forth, and the third moving assembly is used to drive the mounting platform to adjust its height.

[0008] Furthermore, the first movable assembly includes a pair of columns, a suspension, a first power guide rail, and a first movable seat. The two columns are symmetrically fixed on the upper surface of the base on both sides of the placement platform and extend vertically upward. The top of the two columns is fixed with the suspension. The first power guide rail is located below the suspension, and the first movable seat is movably mounted on the first power guide rail.

[0009] Furthermore, the second movable assembly includes a mounting bracket, a second power guide rail, and a second movable seat. The mounting bracket is fixed to the lower end of the second movable seat, the second power guide rail is arranged below the mounting bracket, and the second movable seat is movably mounted on the second power guide rail.

[0010] Furthermore, the third movable assembly includes a mounting base and a first electric push cylinder. The mounting base is fixed to the lower end of the second movable base, and the first electric push cylinder is fixed to the lower end of the mounting base and extends vertically downward. The mounting platform is mounted on the end of the telescopic rod of the first electric push cylinder.

[0011] Furthermore, the grinding mechanism includes side seats, a pair of drive rollers, a grinding belt, and a drive motor. The four side seats are fixed above the base and located on the four sides of the placement platform. Each side seat has a side groove. The two drive rollers are rotatably installed on both sides of the side groove. The grinding belt is mounted on the two drive rollers. The drive motor is fixed on the top of the side seat and fixedly connected to the end of one of the drive rollers.

[0012] Furthermore, the gas distribution mechanism includes a gas distribution cylinder, a piston, a second electric push cylinder, a connecting arm, and a gas guide pipe. The gas distribution cylinder and the piston are respectively fixed on the top of the mounting platform. The piston is slidably fitted into the gas distribution cylinder. A connecting arm is fixedly connected to the side of the piston. The connecting arm slidably extends through to the outside of the gas distribution cylinder and is fixedly connected to the end of the telescopic rod of the second electric push cylinder. One end of the gas guide pipe is connected to the gas distribution cylinder, and the other end is connected to the suction cup.

[0013] Furthermore, several spherical grooves, all of which are open to the outside, are evenly distributed above the placement platform. Rolling balls are rolled in each of the spherical grooves, with the parts of the rolling balls exposed above the placement platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model provides grinding mechanisms on all four sides of the base. The three-axis moving assembly drives the side edge of the cold-rolled steel plate to contact the grinding mechanism on the corresponding side for polishing. Compared with the traditional polishing method, the entire process does not require disassembling and reassembling the fixture to adjust the position of the cold-rolled steel plate, saving time and effort. Moreover, the polishing process has high continuity, saving time and greatly improving the efficiency of cold-rolled steel plate polishing.

[0016] 2. When the cold-rolled steel sheet is placed on the placement table, the rolling ball abuts against the lower surface of the cold-rolled steel sheet. When the three-axis moving assembly moves the cold-rolled steel sheet, the rolling ball rolls, which can reduce the friction when the cold-rolled steel sheet moves, ensuring a smoother and more stable movement process. In addition, it can reduce the wear on the lower surface of the cold-rolled steel sheet and ensure the appearance quality of the cold-rolled steel sheet. Attached Figure Description

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-6 The present invention provides a deburring device for processing cold-rolled steel plates, including a base 1, a placement platform 2 for placing cold-rolled steel plates fixed on the base 1, a grinding mechanism 3 for grinding and deburring the side edges of the cold-rolled steel plates arranged on the four sides of the placement platform 2 above the base 1, an installation platform 8 arranged above the placement platform 2 via a three-axis moving assembly 4, a suction cup 81 for holding the cold-rolled steel plates installed below the installation platform 8, and an air distribution mechanism 9 for evacuating or inflating the suction cup 81 on the installation platform 8.

[0028] The three-axis moving group 4 includes a first moving group 5, a second moving group 6, and a third moving group 7. The first moving group 5 is arranged above the placement platform 2, the second moving group 6 is arranged below the first moving group 5, the third moving group 7 is arranged below the second moving group 6, and the mounting platform 8 is arranged below the third moving group 7. The first moving group 5 is used to drive the mounting platform 8 to move left and right, the second moving group 6 is used to drive the mounting platform 8 to move back and forth, and the third moving group 7 is used to drive the mounting platform 8 to adjust its height.

[0029] The cold-rolled steel sheet is placed on the placement platform 2, ensuring that the four edges of the cold-rolled steel sheet are parallel to the four sides of the grinding mechanism 3. Then, the three-axis moving assembly 4 drives the mounting platform 8 to press down until the suction cup 81 is tightly attached to the upper surface of the cold-rolled steel sheet. The gas distribution mechanism 9 extracts the gas from the suction cup 81, reducing the pressure inside the suction cup 81 and firmly holding the cold-rolled steel sheet. Then, the three-axis moving assembly 4 drives the cold-rolled steel sheet closer to one side of the grinding mechanism 3 until it makes contact. The grinding mechanism 3 on that side grinds and polishes the corresponding side edge of the cold-rolled steel sheet. After the polishing of that side is completed, the three-axis moving assembly 4 drives the cold-rolled steel sheet closer to the adjacent grinding mechanism 3 to complete the polishing of the next side edge of the cold-rolled steel sheet. This process is repeated to complete the polishing of all four sides of the cold-rolled steel sheet.

[0030] This invention provides polishing mechanisms 3 on all four sides of the base 1. The three-axis moving assembly 4 drives the side edges of the cold-rolled steel plate to contact the corresponding polishing mechanisms 3 for polishing. Compared with traditional polishing methods, the entire process does not require disassembling and reassembling the fixtures to adjust the position of the cold-rolled steel plate, saving time and effort. Furthermore, the polishing process is highly continuous, saving time and greatly improving the efficiency of cold-rolled steel plate polishing.

[0031] Specifically, the first moving group 5 includes a pair of columns 51, a suspension 52, a first power guide rail 53, and a first moving seat 54. The two columns 51 are symmetrically fixed on the upper surface of the base 1 on both sides of the placement platform 2 and extend vertically upward. The top of the two columns 51 is fixed with the suspension 52. The first power guide rail 53 is located below the suspension 52. The first moving seat 54 is movably installed on the first power guide rail 53. The first moving seat 54 can be driven to move left and right by the operation of the first power guide rail 53. Under the connection of the second moving group 6 and the third moving group 7, the mounting platform 8 can be driven to adjust its left and right position. Thus, when the suction cup 81 holds the cold-rolled steel plate, the left and right movement adjustment of the cold-rolled steel plate can be realized.

[0032] The second moving group 6 includes a mounting frame 61, a second power guide rail 62, and a second moving seat 63. The mounting frame 61 is fixed to the lower end of the second moving seat 63. The second power guide rail 62 is arranged below the mounting frame 61. The second moving seat 63 is movably mounted on the second power guide rail 62. When the second power guide rail 62 is working, it can drive the second moving seat 63 to move back and forth. Under the connection of the third moving group 7, it can drive the mounting platform 8 to achieve back and forth position adjustment. Thus, when the suction cup 81 holds the cold-rolled steel plate, the back and forth movement adjustment of the cold-rolled steel plate can be realized.

[0033] The third moving group 7 includes a mounting base 71 and a first electric push cylinder 72. The mounting base 71 is fixed to the lower end of the second moving base 63. The first electric push cylinder 72 is fixed to the lower end of the mounting base 71 and extends vertically downward. The mounting platform 8 is mounted on the end of the telescopic rod of the first electric push cylinder 72. By extending and retracting the first electric push cylinder 72, its telescopic rod can drive the mounting platform 8 to be raised and lowered. When the first electric push cylinder 72 extends, it can push the mounting platform 8 down, so that the suction cup 81 is in contact with the surface of the cold-rolled steel plate for easy suction. When the telescopic rod of the first electric push cylinder 72 retracts, it can drive the mounting platform 8 up, thereby making room above the placement platform 2 for easy picking and placing of the cold-rolled steel plate.

[0034] Specifically, the grinding mechanism 3 includes side seats 31, a pair of drive rollers 32, a grinding belt 33, and a drive motor 34. The four side seats 31 are fixed above the base 1 and located on the four sides of the placement platform 2. Each side seat 31 has a side groove 311. The two drive rollers 32 are rotatably installed on both sides of the side groove 311. The grinding belt 33 is driven and mounted on the two drive rollers 32. The drive motor 34 is fixed on the top of the side seat 31 and fixedly connected to the end of one of the drive rollers 32. The drive motor 34 drives one of the drive rollers 32 to rotate. The rotating drive roller 32 can drive the grinding belt 33 to rotate. When the side edge of the cold-rolled steel plate contacts the rotating grinding belt 33, friction is generated, which can achieve the effect of grinding and deburring.

[0035] Specifically, the valve train 9 includes a valve train body 91, a piston 92, a second electric push cylinder 93, a connecting arm 94, and a guide pipe 95. The valve train body 91 and the piston 92 are respectively fixed to the top of the mounting platform 8. The piston 92 is slidably fitted inside the valve train body 91. The connecting arm 94 is fixedly connected to the side of the piston 92. The connecting arm 94 slidably extends through to the outside of the valve train body 91 and is fixedly connected to the end of the telescopic rod of the second electric push cylinder 93. One end of the guide pipe 95 is connected to the valve train body 91, and the other end... Connected to the suction cup 81, the second electric push cylinder 93 retracts, and under the action of the connecting arm 94, the piston 92 moves to the side of the second electric push cylinder 93. The fine air guide tube 95 can draw the gas in the suction cup 81 into the gas distribution cylinder 91, realizing the negative pressure suction of the suction cup 81. When the second electric push cylinder 93 extends, under the action of the connecting arm 94, the piston 92 can push the gas fine air guide tube 95 in the gas distribution cylinder 91 back into the suction cup 81, thereby canceling the negative pressure suction of the suction cup 81 on the cold-rolled steel plate.

[0036] Specifically, several spherical grooves 21, all of which are connected to the outside, are evenly distributed above the placement platform 2. Rolling balls 22 are rolled in each of the spherical grooves 21. The parts of the rolling balls 22 are exposed above the placement platform 2. When the cold-rolled steel sheet is placed on the placement platform 2, the rolling balls 22 abut against the lower surface of the cold-rolled steel sheet. When the three-axis moving assembly 4 moves the cold-rolled steel sheet, the rolling balls 22 roll, which can reduce the friction when the cold-rolled steel sheet moves, ensuring a smoother and more stable movement process. In addition, it can reduce the wear on the lower surface of the cold-rolled steel sheet and ensure the appearance quality of the cold-rolled steel sheet.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
