Description

Technical Field

[0001] The invention relates to the technical field of chip cutting equipment, and in particular to an adjustable cutting equipment for processing stainless steel products. Background Art

[0002] Stainless steel products refer to various items made of stainless steel materials, which have many excellent properties. Stainless steel is an alloy steel containing alloy elements such as chromium and nickel. The addition of chromium forms a dense chromium oxide film on its surface. This film can prevent the internal metal from being further oxidized, giving stainless steel good corrosion resistance, making it not easy to rust and corrode in humid, acidic and alkaline corrosive environments. Stainless steel products are widely used in many fields such as architectural decoration, kitchen utensils and tableware, medical equipment, industrial equipment, automobile manufacturing, aerospace, etc., providing high-quality, durable and beautiful products for people's lives and production;

[0003] Stainless steel pipe cutting is the operation of separating and processing tubular materials made of stainless steel. Commonly used methods include mechanical cutting, such as cutting with a sawing machine. It has high cutting accuracy and smoother incisions and is suitable for stainless steel pipes of various diameters. When cutting thicker steel pipes, more heat will be generated, which may cause changes in the metal structure at the incision and produce a heat-affected zone. At the same time, the slag and chips generated by the cutting may adhere to the surface of the steel pipe again, affecting the processing quality of the steel pipe. Therefore, we proposed an adjustable cutting equipment for stainless steel product processing. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an adjustable cutting device for processing stainless steel products, comprising:

[0005] A bottom plate, wherein an upper tube is arranged on the top of the bottom plate, and a lower tube is arranged at a distance between the upper tube and the bottom plate;

[0006] A cutting mechanism, wherein the cutting mechanism is arranged at the interval between the upper tube and the lower tube, and a side of the upper tube and the lower tube close to each other is fixedly connected to the cutting mechanism, and the cutting mechanism is fixedly connected to the top of the bottom plate;

[0007] Wherein, the cutting mechanism comprises:

[0013] Start the lifting assembly, which drives the upper tube, the protective cover and the lower tube to rise. The top of the upper tube receives the stainless steel tube, and the steel tube slides into the upper tube. The fixing assembly starts to fix the steel tube, and the lifting assembly descends and resets. Then the driving assembly is started, and the driving assembly drives the saw blade to rotate to cut the steel tube. At the same time, the driving assembly drives the saw blade to feed and penetrate the steel tube. The driving assembly drives the saw blade to revolve around the steel tube to cut the steel tube. While cutting the steel tube, the jet assembly is started, and the jet assembly sprays out protective gas. The smoke is discharged from the top of the upper tube with the airflow to protect the steel tube during cutting and prevent oxidation and thermal deformation of the steel tube. The airflow passes through the lower tube and the upper tube in turn to generate an upward airflow, which is opposite to the falling direction of the chips and slag, and can slow down their falling speed to avoid splashing. At the same time, it can cool the chips and slag to prevent them from attaching to the inside of the steel tube again. The external air enters the gap between the upper tube and the lower tube through the protective cover, and the external air rises along the outside of the protective gas column. Prevent smoke, chips and slag from entering the inside of the protective cover to prevent them from affecting the operation of the driving component. The external air rises along the outside of the protective gas column to prevent the external air from contacting the welding position and ensure the protective effect of the protective gas on the welding position of the steel pipe. Then start the lifting component again, and the lifting component drives the upper pipe, protective cover and lower pipe to rise again. The fixing component is unfixed, and the cut steel pipe is unloaded from the bottom of the lower pipe. The top of the upper pipe receives another stainless steel pipe and is fixed by the fixing component for processing again.
