Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing devices, in particular to a straightening mechanism for pipe fitting processing. Background Art

[0002] At present, when processing pipe fittings on a pipe fitting production line, most metal pipes have a certain structural bend and need to be straightened. The existing technology usually drives a driving mechanism to drive a horizontally arranged straightening cylinder to move horizontally to straighten the middle pipe fitting.

[0003] For example, a Chinese patent with the application number CN 202221663449.2 discloses a bending and straightening device for metal frame pipe fittings, including a straightening table. A driving seat is slidably installed on the top of the straightening table along its length direction, and a bracket is fixedly connected to the driving seat. A positioning straightening cylinder is rotatably installed on the bracket. When the electric telescopic rod is started, the transverse moving frame can drive the displacement straightening cylinder to move up and down, and then adjust the displacement straightening cylinder to a suitable position above the positioning straightening cylinder, so that the straightening gap between the two corresponds to the metal frame pipe fitting to be straightened, and then the straightening tool fits better with the pipe diameter for subsequent straightening, which is suitable for workpieces with a smaller pipe diameter. However, before the metal pipe is shaped and straightened, it is usually a blank pipe, and a large amount of metal rust often adheres to the surface of the pipe fitting. And this straightening device cannot remove rust. Once the straightening cylinder on it accumulates rust slag, it will cause damage to the surface of the pipe fitting. Summary of the Utility Model

[0004] In view of this, the purpose of the present utility model is to provide a straightening mechanism for pipe fitting processing to solve the technical problem that the existing technology cannot remove rust, and once the straightening cylinder on it accumulates rust slag, it will cause damage to the surface of the pipe fitting.

[0005] Based on the above purpose, the present utility model provides a straightening mechanism for pipe fitting processing, including a straightening table and a clamp arranged on one side of the straightening table. The straightening mechanism further includes:

[0006] A sliding frame, which is installed on the straightening table through a first driving component;

[0007] A straightening cylinder, which is installed on the sliding frame through a second driving component. A positioning frame is rotatably installed on the straightening cylinder, and the positioning frame slides on the sliding frame. Both ends of the straightening cylinder along the sliding direction of the sliding frame are cavity structures, and a chip discharging port is opened at the lower end;

[0008] Two scraping cylinders, which are respectively threadedly installed at both ends of the straightening cylinder.

[0009] Further, the clamp includes:

[0010] A cylinder, with two cylinders respectively and oppositely installed on the straightening table;

[0015] Guide rods, with two guide rods respectively arranged on the straightening table, and the sliding frame is slidably arranged on the guide rods.

[0016] Furthermore, the second driving assembly includes:

[0017] A second driving motor, installed on the sliding frame;

[0018] Rotating members, with two rotating members respectively rotatably installed on the top of the sliding frame, one side of the rotating member is connected to the output end of the second driving motor, and balls are installed on both of the two rotating members;

[0019] Slide bars, with two slide bars respectively fixedly arranged on both sides of the straightening cylinder, and the two balls are respectively slidably arranged on the two slide bars.

[0020] Furthermore, a lapping block is arranged on one side of the straightening table away from the fixture.

[0021] Furthermore, a chip collecting groove is rotatably arranged below the chip discharging port on the positioning frame, and a plug board is inserted at the lower end of the chip collecting groove on the positioning frame.

[0022] The beneficial effects of the present utility model: When using a straightening mechanism for pipe fitting processing of the present utility model, the sliding frame is driven by the first driving assembly to reciprocate on the straightening table, and the rotating members are driven by the second driving assembly to rotate synchronously on the sliding frame. Then, with the cooperation of the balls on both sides and the slide bars, the straightening cylinder can reciprocate slightly back and forth on the sliding frame and simultaneously swing around the pipe fitting, and cooperate with the chip scraping cylinder to complete the grinding of the pipe fitting, thereby realizing the rust removal operation during the straightening process.
