[0018] The following will clearly and completely describe the technical solutions of the present invention in combination with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Embodiment 1: Aiming at the problem that it is impossible to integrate and adapt the positioning structure to synchronize the cutting and grinding processes, and it is difficult to synchronously process the burrs on the end and inner wall after cutting, the following technical solutions are proposed: Refer to Figure 1 - Figure 5 and Figure 8 - Figure 10 As shown in the figure, in this embodiment, a cutting device for outdoor metal furniture pipes with end face grinding includes a pipe feeding box 1, a primary feeding frame 2 and a secondary feeding frame 3. An arranging plate 8 is arranged in the pipe feeding box 1, and a pipe hole for discharging the pipe body 7 is opened at the lower end of the pipe feeding box 1 corresponding to the arranging plate 8. The primary feeding frame 2 and the secondary feeding frame 3 are axially aligned with the pipe hole and are both provided with feeding components for intermittently pushing the pipe body 7; Pre-aligning mechanisms 4 are symmetrically arranged on both sides between the primary feeding frame 2 and the secondary feeding frame 3, and a cutting and grinding component 5 for cutting and grinding the pipe body 7 is installed on the pre-aligning mechanism 4. When cutting the pipe body 7, first, the pipe feeding box 1 completes the continuous advancement of the pipe body 7, and then the feeding components respectively arranged on the primary feeding frame 2 and the secondary feeding frame 3 complete the continuous feeding of the pipe body 7. When advancing to the required cutting length, the cutting and grinding component 5 continuously cuts and grinds the pipe body 7, so as to achieve the synchronous cutting and grinding during the cutting process of the metal furniture pipe, reduce the turnover times of materials and shorten the processing cycle, and improve the cutting processing efficiency of the pipe; Refer to Figure 3 - Figure 5 As shown in the figure, the cutting and grinding component 5 includes a first cutting knife 11 and a second cutting knife 13. A grinding wheel 10 is coaxially arranged with the first cutting knife 11. The end of the grinding wheel 10 is in a conical structure and can be in a coincident contact with the end face of the cut pipe body 7. A friction wheel 12 is coaxially arranged with the second cutting knife 13. The cutting and grinding component 5 reciprocates horizontally and radially on both sides of the pipe body 7; Refer to Figure 3 、 Figure 4 and Figure 9As shown in the figure, the feeding assembly includes a laterally arranged feeding wheel 25 and an auxiliary supporting wheel 28. An extrusion wheel 27 is movably arranged vertically above the feeding wheel 25, and the wheel gap between the feeding wheel 25 and the extrusion wheel 27 is for the pipe body 7 to pass through. Motors four 24 are installed on the outer sides of the front feeding frame 2 and the rear feeding frame 3, and the output ends of the motors four 24 are connected to the feeding wheels 25. Motors five 26 are installed in the middle of the upper ends of the front feeding frame 2 and the rear feeding frame 3. The output ends of the motors five 26 are connected to a wheel seat through threaded rods. The extrusion wheel 27 is rotatably arranged under the wheel seat, and guide blocks 29 vertically slidably connected to the front feeding frame 2 or the rear feeding frame 3 are installed on both sides of the wheel seat. During the cutting process of the pipe body 7, the gap cooperation between the feeding wheel 25 and the extrusion wheel 27 can adapt to pipes with different cross-sectional shapes for continuous feeding. No matter what cross-sectional shape the pipe body 7 is, it can cooperate with the cutting tool one 11 or the cutting tool two 13 in the cutting and grinding assembly 5 to complete the cutting action, and cooperate with the grinding wheel 10 and the friction wheel 12 in the cutting and grinding assembly 5 to complete the rotating all-round grinding action. Under the mutual cooperation of the two, the cutting and grinding can be carried out synchronously; Refer to Figure 8 As shown in the figure, the pre-alignment mechanism 4 includes a bottom plate 16 and a moving plate 17 that are slidably connected to each other. A motor three 18 is arranged outside the bottom plate 16, and the output end of the motor three 18 is equipped with a lead screw 19 extending to the lower side of the moving plate 17. A slide rail 22 is installed on the bottom plate 16, and the moving plate 17 is slidably arranged on the slide rail 22. A sleeve plate threadedly connected to the lead screw 19 is installed at the bottom of the moving plate 17. A machine frame 23 is installed in the middle of the upper surface of the moving plate 17. A motor one 14 and a motor two 15 are respectively installed at the upper ends of a pair of machine frames 23. The output end of the motor one 14 is coaxially connected to the grinding wheel 10, and the output end of the motor two 15 is coaxially connected to the friction wheel 12; It should be noted that during the cutting and grinding processes of the pipe body 7, the quick switching between cutting and grinding is realized through the pre-alignment mechanism 4, and the specific actions are as follows: When the pipe body 7 travels to the required cutting length and stops, at this time, the third motor 18 starts to drive the screw rod 19 to rotate. The rotation of the screw rod 19 drives the movement of the sleeve plate sleeved with the thread, and the moving plate 17 on the sleeve plate drives the cutting knife 11 or the cutting knife 13 installed with the first motor 14 and the second motor 15 to complete the horizontal movement. During this process, the cutting action of the pipe body 7 is completed through the cutting knife 11 or the cutting knife 13. After the cutting is completed, the third motor 18 will continue to be started. The third motor 18 drives the friction wheel 12 to move horizontally to the outside of the cut pipe body 7 and abut against it. Then, the third motor 18 on the other side is started, so that the grinding wheel 10 corresponds to the end face of the cut pipe body 7. At this time, the second motor 15 starts to drive the friction wheel 12 to rotate, thereby driving the pipe body 7 to rotate. The first motor 14 drives the grinding wheel 10 to rotate at a high speed, realizing the grinding of the end of the cut pipe body 7, and the conical grinding wheel 10 can realize the coincidence and fit with the end of the pipe body 7, and finally complete the end face grinding of the pipe body 7; thus, the cutting and grinding are completed synchronously.

[0020] Basic principle: The principle of the present invention is basically similar to the cutting and grinding principles in the prior art. The differences are as follows: The automatic cutting feed and continuous grinding of the pipe are jointly constituted by the parallel cutting structure and the grinding and rotating structure, and the adaptive multi-specification clamping mechanism is supplemented to realize the adaptive continuous advancement of the pipe, so as to reduce the number of material turnover times and shorten the processing cycle.

[0021] Example 2: Refer to Figure 1 、 Figure 7 and Figure 10 As shown, it further includes a pushing component. The pushing component includes an electric push rod 6 installed on the other side of the pipe hole corresponding to the discharge of the pipe feeding box 1. The output end of the electric push rod 6 extends to one end of the pipe feeding box 1 and is connected with an anti-pulling rod 20. The outer end of the anti-pulling rod 20 is connected with a pushing cone plate 21. The arranging plate 8 is bent in an "L" shape. A arranging rack 9 for intermittently discharging the pipe body 7 is installed on the upper surface of one side of the arranging plate 8. During the pushing stage of the cutting process of the pipe body 7, it is realized by the electric push rod 6 driving the anti-pulling rod 20 and the pushing cone plate 21. The anti-pulling rod 20 drives the pushing cone plate 21 to move horizontally. The pipe body 7 stacked through the arranging plate 8 rolls to the corresponding pipe hole position through the arranging rack 9, and then realizes continuous cutting and grinding feeding under the pushing action of the pushing cone plate 21. And after pushing one pipe body 7 is completed, the pushing cone plate 21 and the anti-pulling rod 20 jointly retract and push away the pipe body 7 to be processed that has rolled to the pipe hole position, avoiding the situation of discontinuous pushing; Similar to that in the first embodiment, the feeding assembly includes horizontally arranged feeding wheels 25 and auxiliary supporting wheels 28. An extrusion wheel 27 is movably arranged vertically above the feeding wheels 25. The wheel gap between the feeding wheels 25 and the extrusion wheel 27 is for the pipe body 7 to pass through. Motors four 24 are installed on the outer sides of the front feeding frame 2 and the rear feeding frame 3. The output ends of the motors four 24 are connected to the feeding wheels 25. Motors five 26 are installed in the middle of the upper ends of the front feeding frame 2 and the rear feeding frame 3. The output ends of the motors five 26 are connected to a wheel seat through threaded rods. The extrusion wheel 27 is rotatably arranged under the wheel seat. Guide blocks 29 vertically slidably connected to the front feeding frame 2 or the rear feeding frame 3 are installed on both sides of the wheel seat. It should be importantly noted that: pressure sensors are provided on both the feeding wheels 25 and the extrusion wheels 27, and when the feeding wheels 25 and the extrusion wheels 27 clamp the pipe body 7, they can real-time feedback the clamping force, and will adjust the rotation speeds of the motor one 14, the motor two 15, the motor four 24 and the motor five 26 according to the feedback clamping force, so as to solve the problem of uneven grinding caused by the eccentric vibration of the special-shaped pipe. And this feedback control grinding assembly can be real-time intelligently controlled through the terminal host computer, and finally achieve comprehensive grinding and uniform grinding.

[0022] Basic principle: This embodiment is based on the first embodiment. On the one hand, the continuous feeding of the pipes to be processed placed in a chaotic stack is realized through the pushing assembly, and stable intermittent pushing can be achieved, avoiding the situation of discontinuous feeding caused by the skew of the pipes; on the other hand, the pressure sensors added in real-time feedback the clamping force, and the corresponding rotation feeding speed is adjusted according to the feedback clamping force to solve the uneven grinding caused by the eccentric vibration of the special-shaped pipe; under the mutual cooperation of the two, the purpose of synchronous intermittent continuous pushing and uniform grinding can be achieved.

[0023] Embodiment Three: Refer to Figure 1 - Figure 10 As shown, this embodiment combines the first embodiment and the second embodiment. A method for cutting outdoor metal furniture pipes with end face grinding includes the following steps: S1: The pushing stage in the cutting process of the pipe body 7: It is realized by the electric push rod 6 driving the anti-pulling rod 20 and the propulsion cone 21. Among them, the anti-pulling rod 20 drives the propulsion cone 21 to move horizontally. The pipe body 7 stacked by the arranging plate 8 rolls to the corresponding pipe hole position through the arranging frame 9, and then realizes continuous cutting and grinding feeding under the pushing action of the propulsion cone 21. And after pushing one pipe body 7 is completed, the propulsion cone 21 and the anti-pulling rod 20 retract together and push open the pipe body 7 to be processed that rolls to the pipe hole position, avoiding the situation of discontinuous pushing. S2: Cutting stage of the pipe body 7: When the pipe body 7 travels to the required cutting length and stops, at this time, the third motor 18 starts to drive the screw rod 19 to rotate. The rotation of the screw rod 19 drives the movement of the sleeve plate sleeved with threads, and the moving plate 17 on the sleeve plate drives the cutting knife one 11 or the cutting knife two 13 installed with the first motor 14 and the second motor 15 to complete the horizontal movement. During this process, the cutting action on the pipe body 7 is completed through the cutting knife one 11 or the cutting knife two 13; S3: Grinding stage of the pipe body 7: After cutting is completed, the third motor 18 will continue to be started. The third motor 18 drives the friction wheel 12 to horizontally move to the outside of the cut pipe body 7 and abut against it. Then the third motor 18 on the other side is started to make the grinding wheel 10 correspond to the end face of the cut pipe body 7. At this time, the second motor 15 starts to drive the friction wheel 12 to rotate, thereby driving the pipe body 7 to rotate. The first motor 14 drives the grinding wheel 10 to rotate at a high speed, realizing the grinding of the end of the cut pipe body 7. And the conical grinding wheel 10 can realize the coincidence and cooperation with the end of the pipe body 7, and finally complete the end face grinding of the pipe body 7; thus, the cutting and grinding are completed synchronously; S4: In S3, pressure sensors are provided on both the feed wheel 25 and the extrusion wheel 27, and when the feed wheel 25 and the extrusion wheel 27 clamp the pipe body 7, they can real-time feedback the clamping force, and will adjust the rotation speeds of the first motor 14, the second motor 15, the fourth motor 24 and the fifth motor 26 according to the feedback clamping force, so as to solve the problem of uneven grinding caused by the eccentric vibration of the special-shaped pipe, and this feedback control grinding component can be real-time intelligently controlled through the terminal upper computer, and finally realize comprehensive grinding and uniform grinding.

[0024] In summary: On the one hand, the present invention realizes the continuous feeding of the to-be-processed pipes placed in a chaotic stack through the pushing component, can realize stable intermittent pushing, and avoid the situation of discontinuous feeding caused by the skew of the pipes; supplemented by the cross-process integration method of simultaneous cutting and grinding to realize the continuous processing of metal pipes and improve the pipe cutting processing efficiency; on the other hand, the pressure sensor added in real-time feedbacks the clamping force, and adjusts the corresponding rotation feeding speed according to the feedback clamping force, solving the uneven grinding caused by the eccentric vibration of the special-shaped pipe; Under the mutual cooperation of the two, the cutting device for outdoor metal furniture pipes adopts a parallel cutting structure and a grinding and rotating structure to jointly constitute the automatic cutting feed and continuous grinding of the pipes, and is supplemented by an adaptive multi-specification clamping mechanism to realize the adaptive continuous advancement of the pipes, achieving the purpose of reducing the number of material turnover times and shortening the processing cycle.
