The steel grades for JIS mechanical structures are: S + carbon content + letter code (CK), in which the carbon content is represented by the intermediate value & times; 100, the letter C: represents carbon, and K: represents steel for carburizing. For example, the carbon content of carbon coil s20c is 0.18-0.23%. The grades of silicon steel sheets in China and Japan are.

According to different metallographic structure of stainless steel, it is divided into semi Ferritic and semi martensitic stainless steel pipe, martensitic stainless steel pipe, austenitic ferritic stainless steel pipe, it must be moved, moved and moved for a long distance. If there is no bag, there will be scratches and scratches on the surface, which will affect the appearance of the surface.

Design and research of high precision stainless steel pipe stainless steel pipe has many advantages such as high strength, good corrosion resistance, strong impact resistance and so on, which makes it widely used in various fields of life. With the continuous improvement of automation, people have higher and higher requirements for the cutting quality of stainless steel pipe. At present, there are still many deficiencies in pipe cutting in China, which seriously restricts China's industrial development. Therefore, recently, the research on pipe cutting machine with high precision, high automation, high cutting quality and high cutting efficiency has become the research focus and difficulty of relevant disciplines, and it is also the inevitable trend of the further development of China's industry. Firstly, the intermittent cutting method of planetary bisymmetric eccentric installation can reduce the cutting deformation of stainless steel pipe and improve the cutting accuracy; Secondly, the tool of the intermittent stainless steel pipe cutting machine is eccentrically installed on the planetary gear to complete the rotation at the same time of revolution. Therefore, only one main motor can drive two tools to rotate. The mechanical structure reduces the use of the motor, improves the use efficiency of the motor and reduces the manufacturing cost of the equipment; Then,603 stainless steel plate, the main components of the intermittent pipe cutter are analyzed by using SolidWorks 3D solid software and ANSYS finite element analysis software. ANSYS software verifies the rationality of the structure and improves the service life of the pipe cutter. At present, there are still many deficiencies in pipe cutting in China, which seriously restricts China's industrial development. Therefore, recently, the research on pipe cutting machine with high precision, high automation, high cutting quality and high cutting efficiency has become the research focus and difficulty of relevant disciplines, and it is also the inevitable trend of the further development of China's industry. Firstly, the cutting characteristics of the intermittent stainless steel pipe cutter in the cutting process are analyzed, and the cutting force in the cutting process is calculated. Secondly, the overall cutting scheme of the intermittent stainless steel pipe cutter is determined, and the structure is designed. Then, the finite element analysis is carried out for the important parts of the intermittent stainless steel pipe cutter, The reliability of its strength and stiffness is verified. In the design process of intermittent stainless steel pipe cutting machine, the combination of theoretical analysis and computer simulation is used to verify the feasibility of the design, theoretical analysis and structural design, and verify the rationality of the structure. This paper aims to design a pipe cutting machine with high automation, compact structure and high cutting precision so as to improve the cutting quality of stainless steel pipe and bring more economic and social benefits to the enterprise. This paper comprehensively analyzes the research on stainless steel pipe cutting machines at home and abroad, draws lessons from the advanced structural design of relevant foreign pipe cutting machines, and makes a comparative analysis and Research on the characteristics of easy deformation and difficult cutting of stainless steel pipes. Taking the stainless steel pipe with diameter of 100mm ~ 150mm and wall thickness of 0mm ~ 5mm as the design object, and based on the structure of the existing planetary pipe cutting machine, but also reduce the deformation of stainless steel pipe in the cutting process. Professional L stainless steel pipe, s stainless steel pipe and 904L stainless steel pipe have large quantity, excellent quality and low price, fire resistance, water resistance, high temperature resistance, strong and durable, safe and reliable and improve the quality of cutting surface.

300 series & mdash; Chromium nickel austenitic stainless steel.

system.2D cold rolled, heat treated, pickled or similar matt surface.

There are about 45 types of hot rolled (hot) stainless steel pipes with a diameter of 54-480mm and 36 types with a wall thickness of 5-45mm. There are 65 types of cold drawn (rolled) stainless steel pipes with a diameter of 6-200mm and 39 types with a wall thickness of 0.5-21mm.

Batch size: a small number of single batch products will affect the unit price.

This kind of steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded steel pipe (slotted pipe). According to different manufacturing processes, cold drawing and cold rolling. According to the section shape, it can be divided into circular pipe and special-shaped pipe. Circular steel pipe is widely used, but there are also some square, rectangular, hexagonal, equilateral triangle Octagonal and other special-shaped stainless steel pipes.

supply.The rolling of cold drawn (rolled) seamless steel pipe is more complex than that of hot rolled (seamless steel pipe). The first three steps of their production process are basically the same. The difference starts from the fourth step. After the round tube blank is emptied, it needs to be started and annealed. After annealing, pickling shall be carried out with special acid. After pickling, apply oil. Then it is followed by multi pass cold drawing (cold rolling) and special heat treatment. After heat treatment, it will be straightened.

3. Domestic wce20 cerium tungsten electrode is used for electrode data. The shape and diameter of the end of cerium tungsten electrode have a great impact on the fluctuation of welding process and weld formation.

The steel strip can be delivered without heat treatment under the condition that all properties meet the standard requirements. Ordinary drawing grade steel strip is allowed to be delivered without heat treatment.
