Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting machines, in particular to a tube laser cutting machine capable of drawing materials. Background Art

[0002] Laser cutting machines focus laser light emitted from a laser source through an optical system into a high-power, high-density laser beam. The laser beam strikes the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the beam and workpiece move relative to each other, a slit is formed in the material, achieving the desired cutting effect. Because the mechanical portion of the laser cutter head does not contact the workpiece, it does not scratch the surface during operation, leading to the increasing use of laser cutting machines.

[0003] During the drawing process, the existing laser cutting machine is prone to slippage when clamping pipes of different diameters due to the different diameters of the pipes. Utility Model Content

[0007] As a preferred embodiment of the above technical solution, the top end of the bottom support frame is connected to a grinding pad, and the bottom end of the top mounting frame is connected to another grinding pad.

[0008] Under the action of two sets of abrasive pads, the pipes required for drawing are wrapped, which increases the friction between the bottom support frame and the top mounting frame and the pipes in direct contact, thereby avoiding slippage and ensuring the stability of the pipe clamping during the drawing process.

[0009] As a preferred embodiment of the above technical solution, the side walls of the upper clamping block are installed with guide side plates.

[0010] Under the guidance of the guide side plate, the upper clamping block is guided to dock with the top end of the lower clamping block stably and smoothly.

[0012] With the use of the elastic mechanism, the upper clamping block and the lower clamping block can be conveniently connected, installed and disassembled, thereby ensuring the working efficiency of the device during use.

[0013] The beneficial effects of the utility model are:

[0014] In this application, the pipe to be pulled is placed on the bottom support frame for support, and the upper clamping block and the lower clamping block are initially locked with the help of the limiting mechanism.
