[0047] The application also provides a machining method of the stainless steel flange turning device, including the following steps:

[0048] S1, the T-shaped flange 33 is contacted with the second cutting knife 15 after being rotated by the rotation of the main shaft 32, so that the T-shaped flange 33 is turned;

[0049] S2, the first rotating shaft 11 is rotated by starting the driving motor 10 during the cutting process, the first rotating shaft 11 drives the gear 12 to rotate, the gear 12 moves the first cutting knife 14 and the second cutting knife 15 through the rack 13, at this time, the first cutting knife 14 is retracted after cutting for a period of time, and the heat is accumulated at the cutting edge of the first cutting knife 14, at this time, the first cutting knife 14 is retracted, the second cutting knife 15 is extended to realize tool changing, avoid the high concentration of cutting heat caused by continuous processing, avoid the oxidation and diffusion wear of the cutting tool due to high temperature, and cause the blade edge to crack or plastic deformation;

[0050] S3, the liquid pump 7 is started at the same time to extract the cooling liquid in the liquid collecting frame 6 through the liquid pump 7, and then the cutting position is cooled by the water outlet pipe 9 to reduce the thermal stress generated by cutting and protect the formed workpiece;

[0051] S4, the T-shaped flange 33 is taken out after being cut, and the work is completed.

[0052] Working principle:

[0053] In the working process, the main shaft 32 is rotated to drive the T-shaped flange 33 to rotate and contact the second cutting knife 15, so as to turn the T-shaped flange 33. In this process, the material of the T-shaped flange 33 is stainless steel, and the thermal conductivity of stainless steel is low. The cutting heat is highly concentrated on the cutting edge and the cutting area. At this time, the driving motor 10 is started to drive the first rotating shaft 11 to rotate, the first rotating shaft 11 drives the gear 12 to rotate, the gear 12 drives the first cutting knife 14 and the second cutting knife 15 to move through the rack 13. At this time, the first cutting knife 14 accumulates heat on the cutting edge after cutting for a period of time. At this time, the first cutting knife 14 retracts, and the second cutting knife 15 extends to realize tool changing. When cutting the T-shaped flange 33, the same tool can be avoided because of the high concentration of cutting heat caused by continuous machining, and the tool can be avoided from oxidation, diffusion wear, blade collapse or plastic deformation caused by high temperature, so as to improve the tool life;

[0054] At the same time, when cutting the T-shaped flange 33, because the material of the T-shaped flange 33 is stainless steel, it is difficult to break the chip because of its high plasticity and toughness. At this time, the driving motor 10 is started to drive the first cutting knife 14 and the second cutting knife 15 to move to complete tool changing. Because the cutting position changes, the cutting angle also changes. When the second cutting knife 15 advances, it will cut the continuous chip to make it fall on the surface of the filter screen 4, so as to be recycled. At the same time, it can effectively avoid a large amount of continuous chips generated during cutting, avoid continuous long chips scratching the workpiece or damaging the tool, and finally avoid the chip from sticking to the tool during cutting, reduce the friction resistance, avoid further heating, and improve the cutting effect;

[0055] When cutting the T-shaped flange 33, the liquid pump 7 is started to pump out the cooling liquid in the liquid collecting frame 6 through the liquid pump 7, and then the cutting position is cooled by the water outlet pipe 9 to reduce the thermal stress generated during cutting and protect the formed workpiece. At the same time, the sprayed cooling liquid will bring the cut chip to the surface of the supporting block 34, avoiding the chip from flying around and affecting the cutting effect, and improving the collection of cutting and facilitating the subsequent recycling.

[0056] Meanwhile, the motor 10 drives the cam 16 to rotate, and the cam 16 drives the moving plate 17 to move downwards, and the moving plate 17 drives the pushing plate 22 to displace to one side along the side slope of the moving plate 17, and the moving plate 17 exerts pressure on the second limiting block 31 through the pushing wheel 24 after displacement, and the supporting block 34 is pressed down at this time, and since the top of the moving plate 17 is a plane, the moving plate 17 will be instantly popped out due to the elastic force of the first spring 21 when the cam 16 rotates away from the limit position, and at this time, the tension of the tension spring 30 and the elastic force of the third spring 35 are instantly released, which will cause the filter screen 4 to vibrate, so as to push the chips on the surface of the filter screen 4 to one side of the filter screen 4, thereby avoiding accumulation and better facilitating collection and improving work efficiency.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.

A device for turning a stainless steel flange according to claim 8, characterized in that The nozzle of the water outlet pipe (9) corresponds to the contact surface of the second cutting knife (15) and the T-shaped flange (33), so that the second cutting knife (15) is conveniently cooled, the limiting groove (19) corresponding to the first limiting column (18) is longitudinally arranged, and the limiting groove (19) corresponding to the second limiting column (23) is transversely arranged.

10. A method of machining a stainless steel flange turning device according to any one of claims 1 to 8, characterized in that, The method comprises the following steps: S1, the main shaft (32) is started to drive the T-shaped flange (33) to rotate and contact the second cutting knife (15), so that the T-shaped flange (33) is turned; S2, in the cutting process, the driving motor (10) is started to drive the first rotating shaft (11) to rotate, the first rotating shaft (11) drives the gear (12) to rotate, the gear (12) drives the first cutting knife (14) and the second cutting knife (15) to move through the rack (13), at this time, the first cutting knife (14) is contracted after cutting for a period of time, and the heat is accumulated at the cutting edge of the first cutting knife (14), at this time, the first cutting knife (14) is contracted, the second cutting knife (15) is extended to realize tool changing, so as to avoid the high concentration of cutting heat caused by continuous machining, and avoid the oxidation, diffusion wear, blade edge cracking or plastic deformation of the cutting tool caused by high temperature; S3, at the same time, start the liquid pump (7) to extract the cooling liquid inside the liquid collecting frame (6) through the liquid pump (7), and then through the water outlet pipe (9) to cool the cutting position, so as to reduce the thermal stress generated by cutting to protect the formed workpiece; S4, after cutting the T-shaped flange (33), take it out, and complete the work.
