[0017] 4. The annular grinding equipment for producing and processing building pipe fittings generates friction by the rotation and movement of the building pipe fittings in the knife ring frame, which contacts the arc scraper, forcing the pad and the arc scraper to deflect on the cutter seat, and cooperates with the top support and rebound effect of the reset part to make the accommodating groove contact the protrusion or burr on the surface of the building pipe fitting to share the load, avoiding a single position on the arc scraper to bear too much load and cause blade loss, and uses the reset bent rod to bear the thrust of the pad and the arc scraper, so that the sliding rod slides in the sleeve and squeezes the spring part to deform, and cooperates with the rebound force of the spring part to ensure the recovery effect of the sleeve, thereby improving the scraping effect on the surface of the building pipe fitting, so as to ensure the service life and processing efficiency of the sleeve.

A sleeve 352 is fixedly mounted on the inclined table of the fixed seat 351. A limiting collar 355 is fixedly mounted on the inner wall of one end of the sleeve 352 away from the fixed seat 351. A slide rod 353 is slidably adapted on the inner edge surface of the limiting collar 355. One end of the slide rod 353 extends to the inside of the sleeve 352 and slides with the inner edge surface of the sleeve 352. The end of the slide rod 353 extending to the inside of the sleeve 352 is fixedly connected to a spring member 356. The spring member 35 One end of the sliding rod 353 away from the slide bar 353 is fixed to the inner wall of the sleeve 352, and one end of the sliding rod 353 away from the spring member 356 is fixedly connected to the reset bent rod 354. One end of the reset bent rod 354 away from the sliding rod 353 is ball-hinged with the outer edge surface of the fixing seat 351. The reset bent rod 354 receives the thrust of the pad 341 and the arc scraper 342, so that the sliding rod 353 slides in the sleeve 352 and squeezes the spring member 356 to deform. With the resilience of the spring member 356, the recovery effect of the sleeve 352 is ensured, and the scraping effect on the surface of the building pipe fitting is improved.

[0026] During operation, the construction pipe is rotated and moved in the knife ring frame 32, and the friction force is generated by the contact with the arc scraper 342, forcing the pad 341 and the arc scraper 342 to deflect on the cutter seat 33. The reset bent rod 354 is used to receive the thrust of the pad 341 and the arc scraper 342, so that the slide rod 353 slides in the sleeve 352 and squeezes the spring member 356 to deform. The rebound force of the spring member 356 is cooperated to ensure the rebound and reset effect of the sleeve 352, so that the accommodating groove 343 contacts the protrusions or burrs on the surface of the construction pipe to share the load, thereby avoiding a single position on the arc scraper 342 from being subjected to excessive load and causing blade loss.

[0027] The following is a detailed description of the working principle of the annular grinding equipment used in the production and processing of building pipe fittings.

[0028] When in use, the staff places the building pipe fittings between the driving rotating member 51 and the auxiliary rotating member 52, and drives the positioning arc plate 514 to move by the extension and retraction of the output shaft of the first cylinder 513, and drives the auxiliary positioning arc plate 524 to move by cooperating with the extension and retraction of the output shaft of the second cylinder 523, and supports the inner wall of the building pipe fittings to fix the building pipe fittings, and then drives the first turntable 512 to rotate by the rotation of the output shaft of the motor 511 to rotate the building pipe fittings, and then drives the screw rod 43 to rotate by the rotation of the output shaft of the mounting frame 41, so that the sliding plate 44 moves and drives the driving rotating member 51 and the building pipe fittings thereon to move, and utilizes the sliding of the roller 525 in the slide plate 527 to reduce the friction force of the movable support plate 521 and the building pipe fittings thereon when moving, and cooperates with the scraping groove 215 to adapt to the protrusions or burrs on the surface of the building pipe fittings through the contact between the grinding petal 214 and the surface of the rotating building pipe fittings. The position of the grinding flap 214 is used to perform pre-rough grinding. The grinding flap 214 and the scraping groove 215 are used to ensure the grinding degree when the building pipe is roughly ground. The building pipe is rotated and moved in the knife ring frame 32 to contact the arc scraper 342 to generate friction, forcing the pad 341 and the arc scraper 342 to deflect on the cutter seat 33. The reset bent rod 354 is used to receive the thrust of the pad 341 and the arc scraper 342, so that the slide bar 353 slides in the sleeve 352 and squeezes the spring member 356 to deform. The rebound force of the spring member 356 is cooperated to ensure the rebound reset effect of the sleeve 352, so that the accommodating groove 343 contacts the protrusion or burr on the surface of the building pipe to share the load, so as to avoid a single position on the arc scraper 342 from bearing too much load and causing blade loss. Then, the fine grinding member 22 is used to perform more fine grinding on the surface of the building pipe; At the same time, the chip guide arc groove 213 and the gap between the inner fixed ring 212 and the outer ring plate 211 are used to discharge the impurities removed by grinding, and the suction force generated by the suction fan 64 is used to accelerate the circulation and cleaning of the polished impurities in the guide pipe 62, and then the V-shaped impurity removal filter plate 63 is used to filter the impurities, and the impurities scraped and polished are suctioned and filtered. After the grinding process of the building pipe fittings is completed, the building pipe fittings are removed and left for subsequent processing.
