Adjustable dust flushing device for stainless steel saw-cutting and hot-rolling

Abstract

The invention discloses an adjustable dust flushing device for stainless steel saw-cutting and hot-rolling. The adjustable dust flushing device for stainless steel saw-cutting and hot-rolling comprises a saw blade device, a feeding device, a saw-cutting table, an end cropping pit, a coupler and a base. The saw blade device comprises a saw blade cover, water collecting pipes, a water collecting pipe seat, a water inlet pipe, inclined nozzles, an adjusting bolt and a bottom plate. The bottom plate and the saw blade cover are welded; and the lower end of the water collecting pipe seat is connected with the bottom plate through the adjusting bolt. The water collecting pipes are arranged on two sides of the water collecting pipe seat; two sides of the water collecting pipe seat are welded withthe water collecting pipes; the inclined nozzles are uniformly arranged on two inner sides of the water collecting pipes and are connected with the water collecting pipe through bolts; and the water collecting pipe seat and the water inlet pipe are welded. By utilizing the device, the aim of high-efficiently flushing away scrap iron on a saw blade is achieved when a stainless steel rod is saw-cut,the problem of difficulty in saw-cutting the stainless steel rod is solved, the service life of the saw blade is prolonged, and the saw-cutting cost is reduced.

Description

technical field [0001] The invention relates to the field of sawing stainless steel bars, in particular to an adjustable sawing and chipping device for hot-rolled stainless steel. Background technique [0002] Sawing stainless steel has always been a difficult problem. The existing steel blade saws are easy to stick saw teeth when sawing hot stainless steel, because stainless steel contains nickel element, its structure is fine and strong, and its toughness is also high at 750°C to 900°C. The particles inside the super steel structure will not deform, but will slide obliquely, so the particles on the surface of the two steel plates can penetrate into each other and bond closely, showing superplasticity twice that of ordinary steel, which will cause a lot of nickel components to stick to the teeth. Gradually, the saw teeth are covered with "sawdust" and cannot be sawed, and the saw blades need to be replaced frequently. In the long run, a lot of working time is wasted to repl...

[0002] Sawing stainless steel has always been a difficult problem. The existing steel blade saws are easy to stick saw teeth when sawing hot stainless steel, because stainless steel contains nickel element, its structure is fine and strong, and its toughness is also high at 750°C to 900°C. The particles inside the super steel structure will not deform, but will slide obliquely, so the particles on the surface of the two steel plates can penetrate into each other and bond closely, showing superplasticity twice that of ordinary steel, which will cause a lot of nickel components to stick to the teeth. Gradually, the saw teeth are covered with "sawdust" and cannot be sawed, and the saw blades need to be replaced frequently. In the long run, a lot of working time is wasted to replace the saw blades, which not only increases the cost of sawing, but also reduces the work efficiency, thus affecting the output

like Figure 8 As shown, the prior art includes water collecting pipe 14A and water collecting pipe seat 16A, water collecting pipe seat 16A can not be adjusted left and right, and water collecting pipe 14A is a straight pipe, the spray area of ​​water sprayed by the nozzle on the straight pipe is small, can not saw The chips are completely washed away, and the work efficiency is low, resulting in a short service life of the saw blade, which still cannot solve the problem of sawing stainless steel
