Laser cutting machine for thin-walled pipe cutting of on-line pipe making pipe

Abstract

The invention relates to a laser cutting machine for thin-walled pipe cutting of an on-line pipe making pipe. The laser cutting machine for the thin-walled pipe cutting of the on-line pipe making pipecomprises a main body rack; a first movable platform is arranged at the front end of the main body rack; a second movable platform is arranged at the rear end of the main body rack; a rotary laser cutting device is arranged on the first movable platform; a pipe clamping component is arranged at the front end of the rotary laser cutting device; and the second movable platform is provided with a residue blocking component and a discharge component. The laser cutting machine for the thin-walled pipe cutting of the on-line pipe making pipe can be linked with pipe making equipment to carry out on-line cutting on a pipe and can machine a thin-walled pipe; the pipe is not prone to deformation when being clamped; an optical fiber/electrical line pipe is prevented from pulling and winding; and theresidue blocking component is adopted, so that damage to the inner wall of the pipe in the cutting process is avoided, the residue blocking effect is good, and the damage is little during pipe machining.

Description

technical field [0001] The invention relates to the field of cutting thin-walled pipes of online pipe making machines, in particular to a laser cutting machine used for cutting thin-walled pipes of online pipe making machines. Background technique [0002] The existing thin-walled pipe cutting method of the online pipe making machine is to cut off the thin-walled pipe with a fixed size grinding wheel cutting machine after the online pipe making machine seals the thin-walled pipe. There are many ways to determine the size. The simple point is to install a micro switch at a certain length of the discharge port. After the pipe reaches the switch, a circuit is triggered to control the cutting wheel to cut off the pipe. When the grinding wheel is initially cut off, the incision will be deformed, and the incision needs to be reshaped. If it is serious, it will directly cause the materials at both ends to be unusable. The length accuracy is not high, and the grinding wheel often n...

Problems solved by technology

However, it is indeed a difficult problem to add laser cutting after the online tube machine, and no major breakthrough has been made

[0004] In the prior art, the laser cutting machine of ZL2016208172176 for cutting pipes can realize and linkage cutting to a certain extent, and cut pipes at one time without secondary truncation and shaping; however, for thin-walled pipes produced by online pipe making machines When cutting, due to the design of its own structure, its clamping device is easy to deform the thin-walled tube clamp, and its concentricity is not high, and the optical fiber / electrical line tube of the laser is easy to break during the rotation process, which affects the use of the laser life
