Description

[Technical field]

[0001] The utility model relates to the technical field of steel pipe processing, in particular to the technical field of steel pipe straightening devices. [Background technology]

[0002] Steel pipes generally need to be straightened during processing. When straightening slender steel pipes with small diameters and thin walls, the steel pipes will vibrate to a certain extent under the action of the straightening rollers. When the slender steel pipes are almost straightened, the unstraightened part is prone to tail swinging. The thinner the steel pipe, the more serious the tail swinging. The tail swinging of the steel pipe is easy to hit the operator or other workpieces or equipment nearby. Similarly, when the slender steel pipes are just being straightened, the straightened part is prone to head swinging, which is also easy to hit the operator or other workpieces or equipment nearby, which is not safe to use.

An outer sleeve is sleeved on the outside of the protective cylinder, and the bottom of the outer sleeve is connected to a vertically arranged connecting rod. A rotating shaft is fixed on the connecting rod, and the rotating shaft is parallel to the protective cylinder. The end of the rotating shaft is rotatably installed on the straightening device body. A plurality of limiting holes are provided on the connecting rod, and a plurality of nuts corresponding to the limiting holes are fixed on the straightening rotating shaft body. Each limiting hole is equipped with a bolt, which passes through the limiting hole and is screwed into the nut. A mounting frame is provided at the discharge end of the straightening device body, and a plurality of supporting rollers are provided on the mounting frame.

[0005] Preferably, the inner diameter of the protective tube is 3-10 mm larger than the outer diameter of the steel pipe, and the length of the protective tube is 40 cm-100 cm.

[0006] Preferably, the bolt consists of a head, a polished rod section and a threaded section which are connected in sequence, the length of the polished rod section is greater than the depth of the limiting hole, and the outer diameter of the polished rod section is adapted to the inner diameter of the limiting hole.

[0007] Preferably, the limiting holes are distributed on both sides of the rotating shaft.

[0008] Preferably, a vertically arranged protective plate is provided on both sides of the mounting frame.

[0009] Preferably, the outer diameter of the protective sleeve is equal to the inner diameter of the outer sleeve, and a flange is provided on the outer wall of the protective sleeve away from the main body of the straightening device.

[Specific implementation method]

[0015] See also Figure 1 The utility model comprises a steel pipe straightening device with a protective mechanism, comprising a straightening device body 1, a mounting frame 3, a rotating shaft 23, a connecting rod 22, an outer sleeve 21, and a protective cylinder 2. A horizontally arranged protective cylinder 2 is provided near the feed port of the straightening device body 1, and the steel pipe passes through the protective sleeve to enter the straightening device body 1. An outer sleeve 21 is sleeved on the outside of the protective cylinder 2, and the bottom of the outer sleeve 21 is connected to a vertically arranged connecting rod 22. A rotating shaft 23 is fixed on the connecting rod 22, and the rotating shaft 23 is parallel to the protective cylinder 2. The end of the rotating shaft 23 is rotatably mounted on the straightening device body 1. A plurality of limiting holes 24 are provided on the connecting rod 22, and a plurality of nuts 10 corresponding to the limiting holes 24 are fixed on the main body of the straightening rotating shaft 23. Each limiting hole 24 is equipped with a bolt 25, and the bolt 25 passes through the limiting hole 24 and is screwed into the nut 10. A mounting frame 3 is provided at the discharge end of the straightening device body 1, and a plurality of supporting rollers 30 are provided on the mounting frame 3.
