Description

Technical Field

[0001] The utility model relates to the technical field of elbow processing, in particular to an automatic flattening machine for elbow pipe fittings. Background Art

[0002] There are many burrs on the surface of the two perpendicular end faces of the elbow pipe after production. At this time, a flattening machine is needed to flatten the two end faces of the elbow. Generally, a robot is used to clamp the elbow to be processed, and then the end face of the elbow is pressed against the rotating flat plate.

[0003] When using the existing flat-mouth machine, it is necessary to manually take the elbow and then grind the elbow through the flat-mouth machine, which increases the workload of the staff and is inconvenient to use.

[0004] An existing patent (publication number: CN216881223U) discloses an automatic flattening machine for elbows. Through the cooperation between a servo motor, a scraper assembly and a driving component, the waste chips falling on the bottom of the chute will be pushed into a storage box from the chute and the chip inlet by a first scraper. There is no need to manually clean the waste chips at the bottom of the chute, which is convenient and saves trouble.

[0005] However, the above technical solution still has certain defects. When the flattening machine is in use, the staff is required to manually take the bent pipe, and then start the equipment and grind the bent pipe through the flattening machine, which increases the workload of the staff. After working for a long time, the staff is prone to fatigue, which may affect the accuracy of the bending process and may cause safety hazards, thereby causing injuries to the staff. It is inconvenient to grind the bent pipe. Therefore, an automatic flattening machine for elbow pipe fittings is proposed. Utility Model Content
