Under the action of motor 14, the threaded rod 15 rotates to adjust the position of the drive block 18, so that it adjusts the position of the processing tool 111, and then the cylinder 2 19 is started to move the processing tool downward to cut the flange 214. Example

[0023] like Figure 1-6As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the clamping mechanism 2 includes a motor three 21 and a rotating disk 22, the top of the rotating shaft of the motor three 21 is fixedly connected to the bottom of the rotating disk 22, the top of the support plate 13 is fixedly connected to the rotating plate 23, the top of the rotating plate 23 is provided with a rolling groove 24, the bottom of the inner cavity of the rolling groove 24 is overlapped with a ball 25, the top of the rotating disk 22 is fixedly connected to a clamping groove 26, the bottom of the inner cavity of the clamping groove 26 is fixedly connected to a lifting cylinder 27, the top of the lifting cylinder 27 is fixedly connected to a lifting plate 28, the bottom of the inner cavity of the clamping groove 26 is fixedly connected to a fixed column 29, the surface of the fixed column 29 is fixedly connected to a hydraulic cylinder one 210, one end of the hydraulic cylinder one 210 is fixedly connected to a clamping plate one 211, one side of the inner cavity of the clamping groove 26 is fixedly connected to a hydraulic cylinder two 212, one end of the hydraulic cylinder two 212 is fixedly connected to a clamping plate two 213, and the bottom of the inner cavity of the clamping groove 26 is overlapped with a flange 214.

[0024] In this embodiment, by starting the motor three 21, under the action of the motor three 21, the rotating disk 22 drives the flange 214 to rotate, so that the processing tool 111 cuts the inner circle of the flange 214, and then the surface of the flange 214 is drilled by the processing tool 111. When the outer circle needs to be processed, the lifting cylinder 27 is started again to move the flange 214 downward, so that the fixing column 29 passes through the inner circle of the flange 214, and then under the action of the hydraulic cylinder 1 210, the clamp 1 211 clamps the flange 214 from the inside, so that the flange processing does not require frequent replacement of the fixture, and the processing efficiency is higher. This solves the problem that during the flange processing process, different fixtures need to be frequently replaced to facilitate the fine processing of the inner and outer circles of the flange, but frequent replacement of fixtures during the processing process will consume a lot of time, which affects the efficiency of flange processing to a certain extent. Example

[0025] like Figure 1-6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the dust removal mechanism 3 includes a dust suction pipe 31 and a dust suction chamber 32, the top of the dust suction pipe 31 is fixedly connected to the bottom of the inner cavity of the dust suction chamber 32, the top of the inner cavity of the dust suction chamber 32 is fixedly connected with a ventilation pipe 33, the interior of the ventilation pipe 33 is fixedly connected with a telescopic hose 34, one end of the ventilation pipe 33 is fixedly connected with a dust collector 35, and one side of the dust collector 35 is fixedly connected with a dust storage bin 36.

[0026] In this embodiment, by starting the vacuum cleaner 35, under the action of the vacuum cleaner 35, the metal debris in the clamping groove 26 is passed along the dust suction pipe 31 through the ventilation pipe 33 into the dust storage bin 36 for storage, so that the metal debris will not splash everywhere, which is more convenient to use. It solves the problem that a large amount of fine metal debris will be generated during flange processing. Most processing devices use high-pressure air guns to clean them, but high-pressure air guns will cause metal debris to splash everywhere, which is not convenient for subsequent cleaning and has certain inconveniences in use.

[0028] In this embodiment, the flange 214 is placed in the inner cavity of the oil immersion bin 45 and then the electric telescopic rod 42 is started, so that the oil immersion bin 45 drives the flange 214 to move downward into the anti-rust oil in the oil storage bin 41, so that a layer of anti-rust oil adheres to the surface of the flange 214, thereby avoiding direct contact with the air and causing surface oxidation of the flange 214 during storage, which is more convenient to use and solves the problem of needing to store the flange after processing is completed. The surface of the flange directly stored in the warehouse will be oxidized under the action of moisture in the air, causing rust on the surface of the flange, which will cause certain inconveniences in use. Example

[0029] like Figure 7 As shown, the present invention provides a flange processing device and a method for using the same. The manufacturing method of the reinforced concrete prefabricated part forming device comprises the following steps: Step 1: Inner circle finishing: The pre-cast disc is clamped by the clamping mechanism 2 and then finished by the processing mechanism 1; Step 2: Punching the disc: After the disc is clamped in the inner cavity of the clamping groove 26, the position of the processing tool 111 is controlled by the motor 14 to punch the disc; Step 3: burr grinding: after punching, the processed flange is polished by the polishing component 112 to remove the burrs generated during the processing; Step 4: Oil immersion and storage: After the flange with burrs removed is placed in the oil immersion bin 45, the flange is immersed in the anti-rust oil in the oil storage bin 41 through the electric telescopic rod 42, so that a layer of anti-rust oil is attached to the surface of the flange, and then it is stored in the warehouse.

[0030] In summary, if Figure 1-7 As shown, when using the device, by starting the cylinder 12, the height of the support plate 13 can be adjusted to adapt to operators of most heights, and then the pre-cast flange 214 is placed in the clamping groove 26, and then the flange 214 is pushed upward under the action of the lifting cylinder 27, and then the metal disc is clamped under the action of the hydraulic cylinder 212, and then the motor 14 is started. Under the action of the motor 14, the threaded rod 15 rotates to adjust the position of the drive block 18 so that it adjusts the position of the processing tool 111, and then the cylinder 219 is started to move the processing tool downward to cut the flange 214, and at the same time, the motor 3 21 is started. Under the action of the motor 3 21, the rotating disk 22 drives the flange 214 to rotate, so that the processing tool 111 cuts the inner circle of the flange 214, and then the surface of the flange 214 is drilled by the processing tool 111. When the outer circle needs to be processed, the lifting cylinder 27 is started again. , so that the flange 214 moves downward, so that the fixing column 29 passes through the inner circle of the flange 214, and then under the action of the hydraulic cylinder 210, the clamping plate 211 clamps the flange 214 from the inside, so that the flange processing does not need to frequently replace the clamp, and the processing efficiency is higher. At the same time, the setting of the grinding component 112 enables it to grind and remove the burrs generated during the processing of the flange 214. After the processing is completed, the vacuum cleaner 35 is started. Under the action of the vacuum cleaner 35, the metal debris in the clamping groove 26 enters the dust storage bin 36 along the dust suction pipe 31 through the ventilation pipe 33 for storage, so that the metal debris will not splash everywhere, which is more convenient for use. After the processing is completed, the flange 214 is placed in the inner cavity of the oil immersion bin 45, and then the electric telescopic rod 42 is started, so that the oil immersion bin 45 drives the flange 214 to move downward into the anti-rust oil in the oil storage bin 41, so that a layer of anti-rust oil adheres to the surface of the flange 214, avoiding direct contact with the air and causing surface oxidation of the flange 214 during storage, which is more convenient for use.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
