Description

Technical Field

[0001] The invention relates to the technical field of flange processing, and in particular to a punching device for pipeline flange processing. Background Art

[0002] With the continuous development of industrialization, pipe flanges are more and more widely used in various industrial systems. In order to ensure the stable connection and reliable sealing of the pipeline system, drilling on the flange has become a key link. When drilling holes in pipe flanges, a punching machine is generally used. During the operation, a chuck is needed to fix the flange blank, and then the drill bit of the punching machine is lowered to achieve the drilling operation of the flange.

[0003] The existing publication number is: CN115647431B. The present invention provides a processing device and a processing method for a high-sealing pipeline flange, which belongs to the technical field of pipeline flange processing, and comprises a lower bracket, wherein a rotating cylinder 1 is fixedly connected to the upper wall surface inside the lower bracket, and the output end of the rotating cylinder 1 extends to the outer side of the lower bracket and a lower assembly table is installed, and a locking component for firmly locking the pipeline flange is installed on the lower assembly table, and a variable component 1 is installed on the upper bracket, and a variable component 2 is installed on the variable component 1, and a puncher is installed on the variable component 2. The present invention solves the problem that the existing processing device for high-sealing pipeline flanges mostly performs manual locking of the pipeline flanges for drilling holes in the pipeline flanges, which is time-consuming and labor-intensive, and the processing efficiency of the pipeline flanges is low. At the same time, after locking, the pipeline flanges will also change when drilling holes, and the firm locking of the pipeline flanges cannot be guaranteed, which leads to deviations in the punched holes and a high defective rate.

[0004] However, when drilling holes in the flange blank, due to the feed of the drill bit, the debris generated by the drilling will be discharged along the chip groove of the drill bit. However, since the drilling depth of many flanges is large, long strips of debris will be generated. After being discharged, these long strips of debris will be swung along with the drill bit and easily scattered on the drilling workbench, resulting in the need for workers to clean and collect the debris later, resulting in high labor intensity for the workers. Summary of the invention

[0005] In view of this, the present invention provides a punching device for pipe flange processing, which has the function of realizing cleaning the hole of the flange blank. At the same time, multiple sets of punching limit rods are inserted into the mounting holes of the flange blank, thereby avoiding circumferential displacement of the flange blank during the punching process, improving the accuracy of punching the flange blank, ensuring the processing quality of the pipe flange, realizing the collection of debris, avoiding the scattering of debris, facilitating the subsequent reuse of the debris, avoiding workers from manually cleaning the debris, and reducing the labor intensity of workers.
