Cut point.
Further, the air compressor connects the cold air pump by the second tracheae.
Compared with prior art, the beneficial effects of the utility model:
1st, cooling nozzles are installed on cutting machine and blow cold air, the cut point of workpiece produces high temperature when preventing from cutting, and prevents work
The problems such as there is molten skin, skull patch, burn, plug-hole in part, it is ensured that the workpiece quality for cutting out, is to drag-line industry production technique and product
Matter is once big lifting and improvement;
2nd, blowing cold air against cutting grinding wheel can take away the amount of heat of grinding wheel, make grinding wheel work at a constant temperature, this
The service life of grinding wheel is greatly improved, is that user is cost-effective.
3rd, cooling nozzles blow cold air against grinding wheel can make the product port for cutting out more preferably, can improve enterprise product product
Matter, improves the product synthesized competitiveness of enterprise.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.
The cooling system of embodiment drag-line pipe cutting machine, including frame as depicted in figs. 1 and 21, for placing workpiece to be cut
9 workpiece slot 2, air compressor (not shown), the cold air pump 3 of connection air compressor and the cooling spray arranged towards workpiece slot
Mouth 4, workpiece slot 2 is in frame 1.The cold air air outlet 31 of cold air pump 3 connects cooling nozzles 4 by the first tracheae 5.Air
Compressor is that cold air pump 3 provides compressed air, and compressed air process is formed cold air and hot-air by cold air pump 3, cold air from
The cold air of cold air pump 3 sprays from cooling nozzles 4 towards in workpiece slot 2, is embodied as the cut point cooling of workpiece 9, and hot-air is from cold
The hot-air air outlet 32 of air pump is discharged.
The top of frame 1 is provided with the abrasive cut-off wheel 6 for cutting workpiece 9, the position that abrasive cut-off wheel 6 is located at and workpiece slot 2 coordinates
Put, the top of abrasive cut-off wheel 6 is provided with the protective cover 10 for protecting abrasive cut-off wheel 6.Abrasive cut-off wheel 6 in the present embodiment is located at workpiece
