[0002] A grinding machine is a device that grinds workpieces through a high-speed rotating grinding wheel. It can smooth out burrs and uneven areas on steel to a smooth state. It is also one of the main ways to trim steel products.

[0003] Because the workpiece is made of steel, it is inevitable that sparks or flying dust will be generated during the grinding process. Current grinding does not have any protective measures against these, and sparks and flying dust are generally allowed to fly out, which will cause damage to the workers' bodies. In addition, the flying dust and sparks accumulate on the ground or on the workbench, which will also affect subsequent processing. Therefore, a steel grinding machine is proposed.

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] Please refer to Figure 1-3The utility model is a steel grinding machine, comprising a processing table 1, a column 8 is set on one side of the processing table 1, the column 8 is an L-shaped structure, a blocking cover 9 is set on the bottom side wall of the column 8, the outer wall of the blocking cover 9 is detachably embedded with a guide plate 10, the guide plate 10 is communicated with the inside of the blocking cover 9, and the top side wall of the guide plate 10 is fixedly connected with a duct 12, one end of the duct 12 away from the guide plate 10 passes through the column 8 and is detachably connected with a suction fan 11, and the suction fan 11 is detachably connected to the top side wall of the column 8.

[0017] A telescopic rod 13 is detachably embedded in the side wall at the bottom of the column 8, and a connecting column 14 is fixedly connected to the output end of the telescopic rod 13. The connecting column 14 is inserted and fixedly connected in the middle of the top side wall of the blocking cover 9, and the guide plate 10 is sleeved on the output end of the telescopic rod 13. A spring 15 is connected inside the connecting column 14 near the bottom end, and a movable column 16 is set below the connecting column 14. The top end of the movable column 16 extends into the spring 15 and is fixedly connected to the bottom end of the spring 15. A motor 17 is embedded in the middle of the end of the movable column 16 away from the connecting column 14, and a grinding wheel 18 is fixedly connected to the output end of the motor 17.

[0018] The technical effect of this solution is as follows: the metal is placed on the placement plate 6, and then the motor 17 is started to drive the grinding wheel 18 to rotate at high speed, and the grinding wheel 18 is lowered through the telescopic rod 13 to make it fit with the metal part, so as to grind the metal part. At the same time, the blocking cover 9 that descends synchronously will cover the grinding wheel 18, so that the sparks and flying dust generated during the grinding process are blocked, which effectively avoids the damage caused by sparks and flying dust to the staff, and can also avoid excessive accumulation of waste dust affecting subsequent grinding treatment.

[0019] A vertical guide rail 4 is fixedly connected to the top of the processing table 1 and near the edges at both ends, and a transverse guide rail 5 is set above the vertical guide rail 4. The transverse guide rail 5 is slidably connected to the two vertical guide rails 4 through the bottom side walls at both ends. A slider is slidably connected in the transverse guide rail 5, and a placement plate 6 is detachably connected to the top of the slider. A spray plate 7 is fixedly connected to the side wall of one end of the placement plate 6. The spray plate 7 is a hollow inclined structure. A connecting hose 3 is fixedly connected to the side wall of one end of the processing table 1, and a collecting tank 19 is fixedly connected to the bottom side wall of the processing table 1. A water pump 20 is set at one end of the collecting tank 19. A collecting column 2 is fixedly connected to the top edge of the end of the processing table 1 away from the connecting hose 3. The collecting column 2 is communicated with the inside of the processing table 1, and the water pump 20 connects the connecting hose 3 to the collecting tank 19 through a pipeline. The end of the connecting hose 3 away from the processing table 1 is fixedly connected to the middle of one side wall of the spray plate 7.

[0020] The technical effect of this solution is as follows: when necessary, the water pump 20 is started to extract the coolant stored in the collection tank 19 and send it to the spray plate 7 through the connecting hose 3. Finally, the coolant is discharged from the spray plate 7 to the metal parts. The sprayed coolant can reduce the high temperature generated during grinding, thereby avoiding serious negative impact on grinding due to high temperature. Auxiliary agents for grinding can also be sprayed to improve the efficiency of grinding and increase the aesthetics after grinding.

[0021] Specifically, when the utility model is used, after the metal piece to be processed is stably placed on the placement plate 6, the telescopic rod 13 is first started to drive the grinding wheel 18 and the blocking cover 9 to descend. When the grinding wheel 18 is in contact with the metal piece, the blocking cover 9 and the connecting column 14 continue to descend under the action of the spring 15 until the blocking cover 9 is in contact with the metal piece. During the movement, the air duct 12 is synchronously extended and retracted. To ensure smooth operation, the air duct 12 uses a telescopic bellows structure. Then the motor 17 is started to drive the grinding wheel 18 to rotate at a high speed to grind the metal piece. The sparks and flying dust generated by the grinding enter the guide plate 10 and are extracted by the suction fan 11 through the air duct 12 to avoid accumulation. In this process, the placement plate 6 is moved. Move along the vertical guide rail 4 and the horizontal guide rail 5 to achieve the effect of comprehensive movement and adjustment, ensure that the surface of the metal part can be fully processed and processed, and improve the smoothness of grinding. To ensure the stability of the metal part, a limiting structure can be connected to the placement plate 6 to position the metal part to avoid the problem of offset during the grinding process. If necessary, start the water pump 20 to spray the cooling water in the collection tank 19 on the metal part through the spray plate 7. The coolant flow will finally fall into the collection column 2, and then enter the collection tank 19 through the collection column 2 to achieve the function of recycling. To avoid waste, not much coolant is sprayed each time to ensure that a thin layer of coolant can be accumulated on the metal part.
