Description

Rotary module and intelligent laser pipe cutting machine thereof

Technical Field

The invention relates to pipe cutting equipment, in particular to a rotating module and an intelligent laser pipe cutting machine thereof.

Background

In actual manufacturing, since the purchased pipes are generally long, the pipes need to be cut into pieces according to the designed length. A laser pipe cutter is generally selected in consideration of the requirement for flatness of the cut. The existing related equipment mainly adopts a small trailer to drag the long pipe and the laser to be stationary, and the small trailer drives the long pipe to move towards the laser so as to adjust the length of the cut segment. The small trailer is generally driven by a lead screw or a chain, a round hole for clamping the long pipe is formed in the small trailer, a rotating wheel is installed in the round hole and is tightly pressed with the outer wall of the long pipe, and then the rotating wheel rotates to drive the long pipe to rotate circumferentially so that the laser cuts the long pipe for one circle to complete the cutting. This approach has the following major disadvantages:

1. the feeding is troublesome, and the long pipe must pass through the round hole, so manual feeding is needed most of the time, which causes lower efficiency and serious obstacle to the design of the subsequent full-automatic processing technology.

2. The positioning accuracy is not high in the process that the small trailer drives the long pipe to move along the axial direction of the long pipe, the long pipe is generally longer than four meters, if the lead screw is adopted to drive the trolley obviously or cause great manufacturing difficulty, the lead screw has high transmission accuracy under the high-accuracy requirement, the cost is very high, and in addition, the support and the coaxiality of the lead screw are also the problems which are difficult to solve. If the chain drive is adopted, although the cost is low and the structure is simple, the positioning precision is low and the positioning time is long, and the requirement of high-precision cutting cannot be met.

3. Continuous feeding can not be realized by adopting a small trailer, namely feeding can be carried out after the cutting of each long pipe is finished, and the feeding time is relatively long because the processes of clamping and axial positioning are involved. Therefore, the mode of the small trailer cannot break through the current processing efficiency.

To this inventor design an intelligence laser pipe cutting machine, it can realize waiting to cut the automatic feeding of tubular product, location, clamp, cut off, and whole journey can realize unmanned, intelligent.
