Water-cooled slag discharging device and method for realizing water circulation

Abstract

The invention relates to a water-cooled slag discharging device for realizing water circulation. The water-cooled slag discharging device comprises a box body and a bearing assembly, wherein a sliding cavity for storing and moving the bearing assembly is formed in the box body; the bearing assembly is detachably connected into the sliding cavity; the bearing assembly comprises a supporting plate; a refractory plate for resisting laser and collecting residues is connected onto the supporting plate; a water-cooled cavity for storing water is formed between the supporting plate and the refractory plate; the water-cooled cavity is formed along the width direction of the refractory plate and extends along the length direction of the refractory plate; a water storage cavity for storing excessive water of the water-cooled cavity is formed in the box body; the water storage cavity is positioned on one side, far away from the bearing assembly, of the sliding cavity; and a water circulation assembly for recycling cooling water is connected between the water storage cavity and the water-cooled cavity. According to the water-cooled slag discharging device disclosed by the invention, laser rays are subjected to heat reduction and ablation by the refractory plate, the water-cooled cavity and the water storage cavity, so that the laser rays are prevented from deforming the body of a slag discharging trolley, and normal slag discharging of the slag discharging device is ensured.

Description

【Technical field】 [0001] The invention relates to laser cutting machine equipment, in particular to a water-cooled slag discharge device and method for realizing water circulation. 【Background technique】 [0002] At present, with the continuous improvement of the cutting capacity of high-power laser cutting machines, the thickness of cutting metal materials is also gradually increasing. In order to avoid cutting the laser cutting machine when cutting metal sheets, laser cutting manufacturers usually use refractory mud or graphite to coat Laser cutting machine interior to prevent laser burns. However, because the slag discharge trolley at the bottom of the laser cutting machine is right under the laser cutting area, the received laser energy density is high, and the frequency of receiving laser energy is high, so it often happens that the slag discharge trolley cannot be pulled out from the bottom of the machine tool due to thermal deformation caused by the laser. problems, ...

However, because the slag discharge trolley at the bottom of the laser cutting machine is under the laser cutting area, the received laser energy density is high, and the frequency of receiving laser energy is high, so it often happens that the slag discharge trolley cannot be pulled out from the bottom of the machine tool due to thermal deformation caused by the laser. problems, resulting in the inability to achieve faster slag discharge during slag discharge, and the common water-cooled slag discharge method, the water temperature will continue to rise under the action of the laser, so that the heat absorption efficiency of the water to the laser is reduced, which is still very Easy to cause damage to the slag discharge device
