A single tool can solve multiple processing conditions in many aspects, which is more effective and saves time to control costs. It can also be used according to different usage methods and different processing to achieve the maximum efficiency of processing. The chip removal effect is improved through the spiral grooving method, and the cutting front angle of the front tool face and the variable axial back angle method change the front and rear outer diameters to cause unequal cutting forces to meet customer requirements, thereby reducing customer costs, improving customer efficiency, solving the problem of poor stability of the existing traditional method, and improving tool quality.

[0031] like Figures 1 to 4 As shown, the front end blade 1 includes a front end face 101, the front end face 101 is located at the end face of the front end blade 1, the front end blade 1 is formed with a front end face first back angle 102, a front end face second back angle 103, and a front end face back angle wiper edge 104 on the blade face opposite to the workpiece transition surface, the front end face back angle wiper edge 104 is arc-shaped, the outer circle of the front end blade 1 is provided with a first right-hand spiral cutting edge 105, the contour blade 2 includes a second right-hand spiral cutting edge 201, and the second right-hand spiral cutting edge 201 is located near the front end of the contour blade 2 The first step edge 3 includes a third right-hand spiral cutting edge 301, which is located at one end of the first step edge 3 close to the contour cutting edge 2 and close to the second step end cutting edge 8. The third right-hand spiral cutting edge 301 is located at one end of the first step edge 3 close to the contour cutting edge 2 and close to the second step end cutting edge 8. The second right-hand spiral cutting edge 301 is located at the tool face opposite to the workpiece transition surface. A first clearance angle 302 and a second clearance angle are formed, the second step end blade 8 includes a first left-hand spiral cutting edge 801, the first left-hand spiral cutting edge 801 is located at the second step end blade 8 close to the first step blade 3 and close to the second step blade 7, the first left-hand spiral cutting edge 801 is formed with a first clearance angle 802 and a second clearance angle on the blade surface opposite to the workpiece transition surface, the second step blade 7 includes a second left-hand spiral cutting edge 701, the second left-hand spiral cutting edge 701 is located at the second step blade 7 close to the second step end blade 8 and close to the second step rear end blade 9, the second left-hand spiral cutting edge 701 is formed with a third clearance angle 702 and a fourth clearance angle 703 on the blade surface opposite to the workpiece transition surface, the second step rear end blade 9 includes a third left-hand spiral cutting edge 901, the third left-hand spiral cutting edge 901 is close to the second step blade 7 and close to the shank 6, the third left-hand spiral cutting edge 901 is formed with a third clearance angle 902 and a fourth clearance angle on the blade surface opposite to the workpiece transition surface.

[0032] A double helical structure is formed by the first right-hand spiral edge 105 of the front end blade 1, the second right-hand spiral edge 201 of the contour blade 2, the third right-hand spiral edge 301 of the first step blade 3, the first left-hand spiral edge 801 of the second step end blade 8, the second left-hand spiral edge 701 of the second step blade 7 and the third left-hand spiral edge 901 of the second step rear end blade 9. A T-shaped structure is formed by the front end blade 1, the contour blade 2, the first step blade 3 and the second step blade 7. By setting a front double helical structural combined molding contour knife and a rear left-hand spiral structural T-shaped knife, multiple grooving methods under different outer diameters of multiple steps can ensure the consistency of the front angle, and more effectively cut normally under different processing conditions. The second step T-type knife is designed with a left spiral, which can more effectively solve the anti-burr problem in cutting to achieve a better surface finish of the workpiece. It can solve the problem of multiple processing and mismatch of dimensions when conventional tools are processing multiple steps, and more effectively improve the qualified rate of products. At the same time, by reasonably adjusting the parameter size according to different working conditions, it is more convenient to solve the problem effectively, thereby improving efficiency. The surface of the processed product is brighter, eliminating multiple tool changes and multiple processing, and a series of complicated steps. The right-hand spiral cutting edge effectively guarantees chip removal and impact resistance of the front cutting edge, greatly improving the processing life, shortening time and reducing costs while effectively improving efficiency and quality.

[0033] like Figures 4 to 5 As shown, the first connecting rod 4 is provided with a chip suction hole near one end of the cutter head, and a chip suction cavity is provided in the middle of the first connecting rod 4, one end of the chip suction cavity passes through the first connecting rod 4, the second step edge 7 and the middle of the second connecting rod 5 to one end of the tool handle 6, and a first mounting groove is provided on the side of the tool handle 6 near the second connecting end, a first storage box 11 is fixedly installed inside the first mounting groove, a chip discharge pipe 12 is fixedly installed on the top of the first storage box 11, a first suction pump 13 is fixedly installed on one side of the first storage box 11, and a first chip suction pipe 14 is fixedly installed on one side of the first suction pump 13, the first chip suction pipe 14 is located inside the chip suction cavity, a through hole is provided on the side of the tool handle 6 near the first mounting groove, one end of the chip discharge pipe 12 passes through the first mounting groove and extends to the through hole, and a first protective block 15 is rotatably connected to the outside of the through hole and located on the outside of the tool handle 6.

[0034] By starting the first suction pump 13, the first chip suction pipe 14 is used to suck chips from the chip suction hole. The first chip suction pipe 14 is conveniently installed through the chip suction chamber, so that the debris generated when the cutter head is in use can enter the first chip suction pipe 14 from the chip suction hole and be collected by the first storage box 11, thereby improving the effect of debris processing at the cutter head, thereby preventing the accumulation of cutter head debris and affecting the use of the cutter head. The first protective block 15 is then rotated to expose the through hole, so that the chip discharge pipe 12 is exposed, and the debris inside the first storage box 11 is sucked out through the chip discharge pipe 12, and the debris is processed, thereby facilitating the first storage box 11 to collect it again. When the debris inside the first storage box 11 is processed, the first protective block 15 is rotated to the top of the through hole, and the chip discharge pipe 12 is shielded and protected to prevent the chip discharge pipe 12 from being damaged, and to prevent other debris and impurities from entering the first storage box 11 through the chip discharge pipe 12, thereby making it inconvenient for the first chip suction pipe 14 to absorb the debris into the first storage box 11 for storage.

[0035] like Figures 5 to 7 As shown, a groove is provided in the middle of the knife handle 6, and a moving opening 16 is provided on one side of the groove and located on the outer side of the knife handle 6. A fixed block 17 is fixedly installed inside the groove, and a motor 18 is arranged inside the fixed block 17. One side of the motor 18 is fixedly installed with the inner wall of the groove, and a threaded rod 19 is transmission-connected with the output end of the motor 18, and the side of the threaded rod 19 is rotatably connected with the inner wall of the other side of the groove. A moving plate 20 is threadedly connected to one end of the threaded rod 19 close to the motor 18, and both ends of the moving plate 20 are movably connected with limiting rods 21, and the upper and lower ends of the limiting rod 21 are fixedly installed with the inner wall of the groove, and rotating plates 22 are hinged on both sides of the moving plate 20. Moving grooves are provided on both sides of the fixed block 17, and one end of the rotating plate 22 is hinged with a connecting block 23 through the moving groove. The connecting block 23 is located on both sides of the fixed block 17, and one side thereof is movably connected with the inner wall of the moving opening 16, and a moving block 24 is fixedly installed on one side of the connecting block 23.

[0036] Starting the motor 18 causes the motor 18 to drive the threaded rod 19 to rotate along the inner wall of the groove. Through the action of the limiting rod 21, the movable plate 20 moves along the threaded rod 19 in the direction away from the motor 18. When the movable plate 20 moves, the rotating plate 22 deflects, thereby pushing the connecting block 23 to move along the inner wall of the movable opening, so that the connecting block 23 drives the movable block 24 to move from the movable opening to both sides of the tool handle 6, so that the second chip suction pipe 29 on one side of the movable block 24 can collect the splashed debris generated when the cutter head is used, thereby further improving the effect of debris absorption.

[0037] like Figures 7 and 8As shown, the moving block 24 is located inside the moving port 16, and its upper and lower sides are both in contact with the inner wall of the moving port 16, a fixed groove is provided on the side close to the moving block 24, a limiting groove is provided on the inner wall of one side of the fixed groove, a movable block 25 is arranged inside the fixed groove, a limiting block 26 is fixedly installed on one side of the bottom of the movable block 25, and the limiting block 26 is slidably connected to the limiting groove, a second mounting groove is provided on the side of the moving block 24 away from the connecting block 23, a mounting hole is provided at the bottom of the second mounting groove and on the side of the moving block 24 close to the connecting block 23, a second storage box 27 is fixedly installed inside the second mounting groove, a second suction pump 28 is fixedly installed on one side of the second storage box 27, and a second chip suction pipe 29 is fixedly installed on one side of the second suction pump 28 and inside the mounting hole.

[0038] When the connecting block 23 drives the moving block 24 to move outward along the moving opening 16, the limiting block 26 at the bottom of the movable block 25 moves along the limiting groove. When the moving block 24 moves to the outside of the moving opening 16, the second chip suction pipe 29 inside the installation opening is exposed, and then the second suction pump 28 is started to allow the second chip suction pipe 29 to absorb the splashing debris generated when the cutter head is used, so that the debris is collected by the second storage box 27, further improving the effect of debris absorption when the cutter head is used, thereby facilitating improving the use effect of the cutter head.

[0039] like Figures 8 to 10 As shown, two baffles 30 are provided on one side of the moving block 24 close to the second storage box 27, and the two baffles 30 are located at both ends of the second storage box 27. A rotating rod is fixedly installed on one side of the two baffles 30, and one side of the rotating rod is rotatably connected to one side of the moving block 24. A sliding groove is opened on the side of the moving opening 16 close to the baffle 30, and the two baffles 30 are slidably connected to the sliding groove. Fixed plates 31 are provided on both ends of the bottom of the second storage box 27, and one side of the fixed plate 31 is movably connected to the inner wall of the second mounting groove. A compression spring is fixedly installed on the bottom of the fixed plate 31, and a mounting plate 32 is fixedly installed on one end of the compression spring, and the mounting plate 32 is fixedly installed on the inner wall of the second mounting groove.

[0040] The second storage box 27 is conveniently supported and fixed by the mounting plate 32, the compression spring and the fixing plate 31, so that the second storage box 27 can be installed inside the second mounting groove. The baffle plate 30 is rotated, and the fixing plate 31 is pushed away from the mounting plate 32 by the elastic action of the compression spring, so that the fixing plate 31 pushes one end of the second storage box 27 to move out of the second mounting groove, and then the second storage box 27 is taken out for replacement, so that the debris can be easily absorbed by the second storage box 27 and the second chip suction tube 29, thereby increasing the service life of the cutter head and facilitating the use of the combined forming knife.

[0041] Working principle: When in use, by setting the front double-helix structural combined forming contour knife and the rear left-helix structural T-knife, multiple grooving methods can be guaranteed to ensure the consistency of the front angle under multiple steps with different outer diameters, and more effectively cut normally under different processing conditions. The third step T-knife is designed with a left-helix method, which is more effective in solving the anti-burr problem in cutting to achieve a better surface finish of the workpiece, and can solve the problem of multiple processing and size mismatch of conventional tools when processing multiple steps. The spiral grooving method ensures the cutting front angle of the front tool face and the variable axial back angle method changes the cutting force caused by the unequal front and rear outer diameters, thereby improving the stability of the tool quality.

[0042] When the cutter head generates debris during use, the right-hand spiral cutting edge and the groove design of the multi-spiral groove 10 are improved to effectively ensure the chip removal and impact resistance of the front cutting edge. At the same time, the first suction pump 13 is started to drive the debris generated when the cutter head is used into the first chip suction pipe 14 through the chip suction hole, and the debris is collected by the first storage box 11, so as to improve the effect of chip treatment at the cutter head. Then, the motor 18 is started so that the motor 18 drives the threaded rod 19 to rotate along the inner wall of the groove. Through the action of the limiting rod 21, the movable plate 20 moves along the threaded rod 19 in the direction away from the motor 18. When the movable plate 20 moves, the rotating plate 22 is deflected. Thereby, the connecting block 23 is pushed to move along the inner wall of the movable opening, so that the connecting block 23 drives the moving block 24 to move from the movable opening to the two sides of the tool handle 6. When the connecting block 23 drives the moving block 24 to move outward along the movable opening 16, the limiting block 26 at the bottom of the movable block 25 moves along the limiting groove. When the moving block 24 moves to the outside of the movable opening 16, the second chip suction pipe 29 inside the installation opening is exposed, and then the second suction pump 28 is started so that the second chip suction pipe 29 absorbs the splashing debris generated when the cutter head is in use, so that the debris is collected by the second storage box 27, thereby further improving the effect of debris absorption when the cutter head is in use.

[0043] When the first storage box 11 needs to be replaced, the first protective block 15 is rotated to expose the through hole, and the debris inside the first storage box 11 is sucked out through the chip discharge pipe 12, and the debris is processed, so as to facilitate the first storage box 11 to collect again. When the debris inside the first storage box 11 is processed, the first protective block 15 is rotated to the top of the through hole to cover and protect the chip discharge pipe 12 to prevent the chip discharge pipe 12 from being damaged. When the second storage box 27 needs to be replaced, the baffle 30 is rotated to push the fixed plate 31 away from the mounting plate 32 through the elastic action of the compression spring, so that the fixed plate 31 pushes one end of the second storage box 27 out of the second mounting groove, and then the second storage box 27 is taken out for replacement, so as to facilitate the second storage box 27 and the second chip suction pipe 29 to absorb the debris, thereby increasing the service life of the cutter head and facilitating the use of the combined forming knife.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
