Cutting table of angle-adjustable optical fiber laser cutting machine

Abstract

The invention relates to the technical field of laser cutting, in particular to a cutting table of an angle-adjustable optical fiber laser cutting machine. A cutting table body comprises stand columnsand cross rods arranged at the upper edges of the stand columns, wherein the cross rods are fixedly connected with the upper edges of the stand columns; the cross rods are fixedly connected end to end; a movable plate is in hinge joint with one cross rod; a support rod is arranged at one end, far away from the hinge joint end, of the movable plate; double rubber covered rollers are arranged on the cross rod mutually perpendicular with the cross rod connected with the movable plate; groove notches are formed in the middles of the stand columns; and a material receiving plate is clamped in thegroove notches. Compared with the prior art, the cutting table has the following advantages: one end of a to-be-cut workpiece is leaned against the movable plate, the other end of the to-be-cut workpiece is fixed through the double rubber covered rollers, the movable plate can adjust the angle, and the double rubber covered rollers also can be adjusted through different mounting positions in a mounting groove, so that the to-be-cut workpiece can realize fixation of a fixed angle; and in addition, the material receiving plate below can collect fused dripping generated during cutting, so that the cutting table or the surrounding is not polluted.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a cutting table of an angle-adjustable fiber laser cutting machine. Background technique [0002] Fiber laser cutting uses a focused high-energy-density laser beam to irradiate the workpiece. Under the premise of the laser energy density exceeding the laser threshold, the energy of the laser beam and the chemical reaction heat generated by the active gas-assisted cutting process act on the material. This causes the temperature of the laser action point to rise suddenly. After reaching the melting and boiling point, the material begins to melt or vaporize to form holes. With the relative movement of the beam and the workpiece, a slit is finally formed on the material. Laser cutting has the following characteristics. First, laser cutting has no contact, no tool wear, narrow kerf, small heat-affected zone, small incision surface roughness, good incision parallelism, and high p...

AI Technical Summary

Problems solved by technology

The fiber laser cutting machine is mainly composed of a cutting mechanism and a cutting table. The cutting table is used to support the workpiece for cutting. The table structure is simple and the function is single, especially when the fiber laser cuts metal plates such as steel and aluminum magnesium, it will produce high-heat molten drops, which will cause damage or pollution to the cutting table. , to realize the angle placement of the plate on the cutting table
