Description

Pipeline cutting device

Technical Field

The utility model relates to a pipeline cutting field, concretely relates to pipeline cutting device.

Background

In the process of beveling the pipeline, the pipeline is easy to slide, and the accuracy of the beveling track is further influenced.

In the prior art, a clamping mechanism is adopted to clamp a pipeline, so that the pipeline is prevented from sliding. However, the cutting mechanism usually cuts the pipeline from top to bottom, the clamping mechanism usually adopts a left-right clamping mode for avoiding collision with the cutting mechanism, and because the length of one side of the pipeline after beveling is greater than the other side, the distances between the beveling surfaces at two sides of the pipeline and the clamping position are unequal, in the beveling process, the restraining force of the clamping mechanism on two sides of the pipeline is unequal, the stress on two sides of the pipeline is uneven, and further the accuracy of the beveling track is affected.

So set up, the piece of keeping silent can further restrict the displacement of pipeline through the vertical removal of second breach restraint pipeline, has improved the oblique cutting orbit accuracy.

Preferably, as an improvement, the device further comprises a feeding mechanism, wherein the feeding mechanism comprises a feeding unit and a feeding cylinder, the feeding unit can clamp the pipeline, and the feeding cylinder can enable the feeding unit to be close to the clamping mechanism. Compared with manual feeding, the feeding mechanism is more stable in feeding, and abrasion to the pipeline in feeding can be reduced; when a pipeline is obliquely cut twice, the length of the output shaft of the feeding cylinder is fixed, so that the feeding distance is fixed every time, and the distance between two oblique cutting surfaces can be controlled.

Preferably, as an improvement, still include the box, cutting mechanism sets up and is being close to and holds pipe one side tightly, and cutting mechanism includes base member, arm, slitting saw, cutting cylinder, and the one end and the base member of arm rotate to be connected, and the other end and the slitting saw center of arm rotate to be connected, and the output shaft and the arm of cutting cylinder are close to slitting saw one end and rotate to be connected, and the cutting cylinder rotates with the box to be connected. So set up, be close to the pipeline through cutting cylinder drive slitting saw, through rotatory slitting saw, miscut to the pipeline.

Preferably, as an improvement, clamping mechanism, feeding mechanism, cutting mechanism set up in the box, and box one side that the box is close to feeding mechanism is equipped with the box breach, and the remaining side of box is the transparent plate. So set up, the beveling in-process, the piece is controlled in the box, avoids the piece in a confused state of mind to fly, is convenient for clear up.

Preferably, as an improvement, the cutting saw is sleeved with a protective cover which is fixedly connected with the mechanical arm. So set up, prevent that the slitting saw from hindering the people, increase cutting mechanism's security.
