[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) A rust removal device for machining metal bars. When the metal bar needs to be rusted, the worker can put the metal bar in a rust removal box and put a large amount of rust removal liquid in the rust removal box. The servo motor is started to drive the rust removal shaft to rotate, which can drive the centrifugal ring to rotate. Under the action of the rotating centrifugal force, the centrifugal ring can drive the magnetic ball to rise through the iron wire under the dual buoyancy of air and rust removal liquid. When the magnetic force on the metal part is greater than the weight of the metal bar itself, the metal bar rises under the buoyancy of the rust removal liquid. At the same time, the gravity, magnetic force and The buoyancy provides centripetal force for the metal rod. When the magnetic ball rotates above, it will cause the metal rod to move. Traditionally, a stirring device is used when the metal rod contacts the rust removal solution, but this time the stirring device is saved, and the contact area between the metal rod and the solution is increased. In addition, the metal rod can collide with the rust removal rod on the arc plate during movement, further shaking off the rust on the metal rod and improving the rust removal effect of the metal rod. At the same time, the servo motor can control the forward and reverse rotation of the rust removal axis to move the magnetic ball up and down, which can make the metal rod in the solution move irregularly and enhance the rust removal effect.

[0013] (2) A rust removal device for machining metal bars. After rust removal is completed, the worker can pull the pull rod, so that the pull rod drives the opening and closing ring to rotate on the surface of the opening and closing ring, and further causes the moving rod to pull the opening and closing leaves to rotate a certain angle on the surface of the opening and closing ring. When the four opening and closing leaves are fully opened, the rust removal liquid and the metal bar can all flow into the funnel under the action of the centrifugal force of the water flow. The rotary opening and closing mechanism can complete the opening and closing action in a limited space. Compared with other linear opening and closing mechanisms, it can achieve a larger opening and closing angle, and is more stable and continuous than linear motion. Therefore, the opening and closing mechanism can achieve a relatively stable opening and closing action, reducing the shaking and vibration of the metal bar and preventing the metal bar from remaining on the support plate under vibration.

[0014] (3) A rust removal device for machining metal rods. When the rust removal liquid and the metal rod flow onto the filter plate through the funnel and the discharge channel, the rust removal liquid continues to fall into the recovery box through the filter holes on the filter plate, while the metal rod remains on the filter plate. At this time, the timer controls the battery to discharge so that the strong electromagnet is energized, which can adsorb the magnetic block on the other side of the limit plate. Under the adsorption effect, the magnetic block drives the cleaning plate to move forward under the limit of the limit plate, so that when the push block encounters the metal rod, it pushes the metal rod into the salvage box. At the same time, the cleaning brush can clean and push the rust dust and impurities on the filter plate after rust removal, so that the rust dust and impurities also fall into the salvage box. At the same time, the cleaning plate moves backward under the resetting effect of the elastic rubber, and can clean the impurities on the filter plate again. When the cleaning plate returns to its original position, it will generate rapid vibration under the residual force of the elastic rubber, and all the impurities on the cleaning brush will be shaken off into the cleaning box under the vibration.

[0015] (4) This rust removal equipment for machining metal bars, when the metal bars and impurities all fall into the salvage box, the salvage box is filled with water, the motor is started to drive the rotation of the shaft, which can drive the rotation of the salvage plate, and further drive the rotation of the salvage leaves to salvage the metal bars. The provided blocking plate does not affect the entry of the metal bars, and can prevent the metal bars from being thrown out under the effect of rotation. At the same time, the residual impurities remain in the salvage box. After the gold brush rods are all collected, the salvage cover is opened, the metal bars are taken out, and the salvage box is opened at the same time, so that all the sewage is discharged. The metal bars are salvaged through the salvage mechanism, and the impurities are also removed.

[0016] (5) In the rust removal equipment for machining metal bars, after the rust removal liquid flows into the recovery tank, the water pump is started to pump the rust removal liquid back into the rust removal tank, thereby achieving the effect of recycling the rust removal liquid.

Under the action of the rotating centrifugal force, the centrifugal ring 203 is moved by the iron wire in both air and rust removal liquid. The buoyancy of gravity can drive the magnetic ball 204 to rise. When the magnetic force on the metal part is greater than the weight of the metal rod itself, the metal rod rises under the buoyancy of the rust removal liquid. At the same time, the gravity, magnetic force and buoyancy of the metal rod provide centripetal force for the metal rod. When the magnetic ball 204 rotates above, it will cause the metal rod to move. Traditionally, a stirring device is used when the metal rod contacts the rust removal liquid, but this time the stirring device is saved, and the contact area between the metal rod and the solution is increased. In addition, the metal rod can collide with the rust removal rod 208 on the arc plate 207 during movement, further shaking off the rust on the metal rod, thereby improving the rust removal effect of the metal rod.

When the rust removal is completed, the staff can pull the pull rod 406 so that the pull rod 406 drives the The opening and closing ring 403 rotates on the surface of the opening and closing ring 405, further causing the moving rod 402 to pull the opening and closing leaf 401 to rotate a certain angle on the surface of the opening and closing ring 405. When the four opening and closing leaves 401 are fully opened, the rust removal liquid and the metal rod can all flow into the funnel 5 under the action of the centrifugal force of the water flow. The opening and closing action can be completed in a limited space by utilizing the rotary opening and closing mechanism. Compared with other linear opening and closing mechanisms, it can achieve a larger opening and closing angle, and is more stable and continuous than linear motion. Therefore, the opening and closing mechanism 4 can achieve a relatively stable opening and closing action, reduce the shaking and vibration of the metal rod, and prevent the metal rod from remaining on the support plate under vibration.

The motor 703 is started to drive the rotation of the rotating shaft 701, which can drive the rotation of the salvage plate 704, and further drive the rotation of the salvage leaf 705 to salvage the metal rod. The provided blocking plate 706 does not affect the entry of the metal rod and can prevent the metal rod from being thrown out under the rotation effect. At the same time, the residual impurities remain in the salvage box 702. After all the gold brush rods are collected, the salvage cover 707 is opened, the metal rod is taken out, and the salvage box 702 is opened at the same time to discharge all the sewage.

[0023] The cleaning mechanism 8 includes a filter plate 801, both sides of the filter plate 801 are fixedly connected with a fixed plate 802, one side of the fixed plate 802 close to the filter plate 801 is fixedly connected to a limiting plate 803, one side of the limiting plate 803 is slidably connected to a cleaning plate 804, one edge position of one side of the cleaning plate 804 is fixedly connected with a magnetic block 805, one side of the cleaning plate 804 is fixedly connected with a pushing block 806, a bottom of the cleaning plate 804 is fixedly connected with a cleaning brush 807, a side of the cleaning plate 804 away from the pushing block 806 is fixedly connected with an elastic rubber 808, an end of the elastic rubber 808 away from the cleaning plate 804 is fixedly connected with a cleaning box 809, an edge position of one side of the limiting plate 803 is fixedly connected with an electromagnet 810, the electromagnet 810 is electrically connected to a timer 811 through a wire, and the timer 811 is away from the wire.

When the four opening and closing leaves 401 are fully opened, the rust removal liquid and the metal rod can all flow into the funnel 5 under the action of the centrifugal force of the water flow. The rotary opening and closing mechanism can complete the opening and closing action in a limited space. Compared with other linear opening and closing mechanisms, it can achieve a larger opening and closing angle, and is more stable and continuous than linear motion. Therefore, the opening and closing mechanism 4 can achieve a relatively stable opening and closing action, reduce the shaking and vibration of the metal rod, and prevent the metal rod from remaining on the support plate under vibration.

[0024] The recycling mechanism 9 includes a recycling box 901, one side of the recycling box 901 is connected to a water pump 902 through a water inlet pipe, and the side of the water pump 902 away from the water inlet pipe is fixedly connected to a water outlet pipe 903.

[0025] When it is necessary to remove rust from the metal rod, the staff can put the metal rod in the rust removal box 1, and put a large amount of rust removal liquid in the rust removal box 1, start the servo motor 205 to drive the rust removal shaft 201 to rotate, which can drive the centrifugal ring 203 to rotate. Under the action of the rotating centrifugal force, the centrifugal ring 203 can drive the magnetic ball 204 to rise through the iron wire under the dual buoyancy of air and rust removal liquid. When the magnetic force on the metal piece is greater than the weight of the metal rod itself, the metal rod rises under the buoyancy of the rust removal liquid. At the same time, the metal rod is subjected to the combined action of gravity, magnetism and buoyancy. Providing centripetal force, when the magnetic ball 204 rotates above, it will cause the metal rod to move. Traditionally, a stirring device is used when the metal rod contacts the rust removal solution, but in this case, the stirring device is saved, and the contact area between the metal rod and the solution is increased. In addition, the metal rod can collide with the rust removal rod 208 on the arc plate 207 during movement, further shaking off the rust on the metal rod, thereby improving the rust removal effect of the metal rod. At the same time, the servo motor 205 can control the forward and reverse rotation of the rust removal shaft 201 to move the magnetic ball 204 up and down, which can make the metal rod in the solution move irregularly, thereby enhancing the rust removal effect. When the rust removal is completed, the staff can pull the pull rod 406, so that the pull rod 406 drives the opening and closing ring 403 to rotate on the surface of the opening and closing ring 405, and further makes the moving rod 402 pull the opening and closing leaf 401 to rotate a certain angle on the surface of the opening and closing ring 405. When the four opening and closing leaves 401 are fully opened, the rust removal liquid and the metal rod can all flow into the funnel 5 under the action of the centrifugal force of the water flow. The rotary opening and closing mechanism can complete the opening and closing action in a limited space. Compared with other linear opening and closing mechanisms, it can achieve a larger opening and closing angle, and is more stable and continuous than linear motion. Therefore, the opening and closing mechanism 4 can achieve a relatively stable opening and closing action, reduce the shaking and vibration of the metal rod, and prevent the metal rod from remaining on the support plate under vibration.

[0026] At the same time, when the rust removal liquid and the metal rod flow onto the filter plate 801 through the funnel 5 and the discharge channel 6, the rust removal liquid continues to fall into the recovery box 901 through the filter holes on the filter plate 801, while the metal rod remains on the filter plate 801. At this time, the timer 811 controls the battery 812 to discharge so that the strong electromagnet 810 is energized, which can adsorb the magnetic block 805 on the other side of the limit plate 803. Under the adsorption effect, the magnetic block 805 drives the cleaning plate 804 to move forward under the limit of the limit plate 803, so that the pushing block 806 pushes the metal rod when it encounters the metal rod. The rod falls into the salvage box 702. At the same time, the cleaning brush 807 can clean and push the rust, dust and impurities on the filter plate 801 after rust removal, so that the rust, dust and impurities also fall into the salvage box 702. At the same time, the cleaning plate 804 moves backward under the resetting effect of the elastic rubber 808, and the impurities on the filter plate 801 can be cleaned again. When the cleaning plate 804 returns to its original position, it will vibrate rapidly under the residual force of the elastic rubber 808, and the impurities on the cleaning brush 807 will be shaken off into the cleaning box 809 under the vibration. When the metal rod and the impurities all fall into the salvage box 702, the salvage box 702 is filled with water, and the motor 703 is started to drive the rotation of the rotating shaft 701, which can drive the rotation of the salvage plate 704, and further drive the rotation of the salvage leaf 705 to salvage the metal rod. The provided blocking plate 706 does not affect the entry of the metal rod, and can prevent the metal rod from being thrown out under the effect of rotation. At the same time, the remaining impurities remain in the salvage box 702. After all the gold brush rods are collected, the salvage cover 707 is opened, the metal rod is taken out, and the salvage box 702 is opened at the same time, so that all the sewage is discharged. The metal rod is salvaged through the salvage mechanism 7, and the impurities are also removed.
