A feeding module and its automatic laser pipe cutting machine

Abstract

The invention discloses a feeding module and a full-automatic laser pipe cutting machine thereof. The full-automatic laser pipe cutting machine comprises: a feeding module, which is used to load the pipes to be cut into the pipe grooves of the feeding wheel one by one, and then the upper The material wheel rotates so that the pipes to be cut go through the processes of feeding, centering, clamping, cutting, and discharging in sequence; the power module is used to drive the rotation of the pipes at the cutting process to ensure that the pipes are cut in one circle, and at the same time, the The feeding wheel is driven to rotate to complete the process switching; the cutting module is used to cut the pipe through the laser emitted by the laser, and the pipe is relatively fixed in the axial direction, and the laser cutting head moves and positions along the axial direction of the pipe to complete the pipe cutting precise cutting. The invention can realize automatic feeding, and the five processes of feeding, clamping, axial alignment, section cutting, and discharging can be synchronized to realize at least twice or more increase in production efficiency. In addition, the method of moving the laser and fixing the pipe can be adapted to more lengths of pipe.

Description

technical field [0001] The invention relates to pipe cutting equipment, in particular to a fully automatic laser pipe cutting machine. Background technique [0002] In actual processing and manufacturing, since the pipes purchased are generally relatively long, they need to be cut into sections according to the design length. Considering the requirements for the flatness of the incision, a laser pipe cutting machine is generally selected. The current related equipment mainly adopts a small trailer to drag the long pipe, the laser does not move, and the small trailer drives the long pipe to move to the laser to adjust the length of the cut section. The small trailer is generally driven by a screw or a chain, and a round hole is opened inside to clamp the long pipe. A rotating wheel is installed in the round hole. The rotating wheel is pressed against the outer wall of the long pipe, and then the rotating wheel rotates to drive the long pipe to rotate in a circle. In order t...

AI Technical Summary

Problems solved by technology

[0003] 1. Feeding is troublesome. Since the long pipe must pass through the round hole, manual loading is required most of the time, which results in relatively low efficiency and serious obstacles to the design of subsequent fully automated processing technologies.

[0004] 2. The positioning accuracy is not high when the small trailer drives the long pipe to move along its axial direction. Considering that the long pipe is generally more than four meters in length, it will obviously cause greater manufacturing difficulty if the lead screw is used to drive the trolley, and Under the requirement of high precision, the lead screw must have relatively high transmission accuracy, and the cost is very high. In addition, the support and coaxiality of the lead screw are also difficult problems to solve.

If the chain drive is used, although the cost is low and the structure is simple, the positioning accuracy is low and the positioning time is long, which cannot meet the requirements of high-precision cutting

[0005] 3. Continuous feeding cannot be realized by using a small trailer, that is, loading can only be carried out after each long pipe is cut, and the loading time is relatively long, because it involves the process of clamping and axial positioning

Therefore, the way of small trailers cannot break through the current processing efficiency
