[0003] like Figure 1 As shown, in the existing enclosure, two parallel and oppositely arranged baffles 11 and a support frame fixedly connected between the two baffles 11 are included. The support frame includes four mutually enclosing and rectangular fixing rods 12, and the four fixing rods 12 are welded end to end. In order to facilitate assembly and welding, the opposite end surfaces of each fixing rod 12 in the length direction are inclined, and the inclined end surfaces of the opposite ends of the same fixing rod 12 are oppositely arranged.

[0004] In the existing pipe cutting machine, there is a machine body 6, a clamp 21 movably mounted on the machine body 6 for clamping the pipe, and a cutting knife 7 movably mounted on the machine body 6 for cutting the pipe. When the pipe needs to be cut, the staff places the pipe on the clamp 21, clamps the pipe with the clamp 21, and then cuts the pipe with the cutting knife 7, and then cuts the pipe to form a fixed rod 12. Since the lengths of the fixed rods 12 are different, the staff needs to manually cut each fixed rod 12 in sections one by one, and such an operation method increases the labor intensity of the staff.

[0005] Therefore, a pipe cutting processing system is needed. Summary of the invention

[0006] In order to reduce the labor intensity of the staff, the present application provides a pipe cutting and processing system.

[0007] The present application provides a pipe cutting system, which adopts the following technical solutions:

[0009] By adopting the above technical solution, when it is necessary to cut the pipe, the staff first adjusts the cutting angle of the cutting knife using the rotating mechanism to facilitate the processing of the inclined end face of the fixed rod, and then places the pipe in the three pipe cutting machines, and uses the clamps of the three pipe cutting machines to clamp the pipe. Then the staff steps on the foot pedal, and uses the electrical connection between the foot pedal and the three pipe cutting machines to start the three pipe cutting machines at the same time, and cut the pipe, and then cut it into several sections of fixed rods. By adjusting the spacing of the three pipe cutting machines, the length of the four fixed rods can be adjusted, and several fixed rods can be cut at one time.

Preferably, in this embodiment, the number of pipe cutters 2 is three, and the three pipe cutters 2 are arranged at intervals along the length direction of the support rods 3, and the three pipe cutters 2 are electrically connected. Specifically, the pipe cutter 2 includes a machine body 6, which is arranged in a rectangular parallelepiped, and one end of the machine body 6 in the length direction is supported by the top plates 31 of the two support rods 3, and the other end of the machine body 6 in the length direction extends in a direction opposite to the ground. The two opposite ends of the machine body 6 in the width direction facing the ground are respectively placed on the surface of the top plate 31 , and then the two support rods 3 support the three pipe cutting machines 2 .

[0038] Reference Figure 2 and Figure 3Preferably, in this embodiment, the number of the adjustment devices 4 is four groups, and the four groups of adjustment devices 4 are respectively located at the four corners of the side of the machine body 6 facing the ground. Specifically, the adjustment device 4 includes a pad 41 welded and fixed to the side of the machine body 6 facing the bottom surface, a fastening bolt 42 that penetrates the top plate 31 and the pad 41, and a fastening nut 43 that is threadedly connected with the fastening bolt 42 and is used to tighten the pad 41. The pad 41 is arranged in a rectangular parallelepiped, and one side of the pad 41 in the thickness direction is welded and fixed to one corner of the machine body 6, and the pad 41 extends horizontally toward the outside of the machine body 6. The other side of the pad 41 in the thickness direction is tightly pressed against the surface of the top plate 31. The pad 41 is provided with a through hole 411 for the fastening bolt 42 to penetrate along its thickness direction. The thickness direction of the top plate 31 is parallel to the vertical direction, and the top plate 31 is provided with a long waist-shaped hole 32 that penetrates the opposite sides of its thickness direction, and the length direction of the long waist-shaped hole 32 is parallel to the length direction of the support rod 3. The nut of the fastening bolt 42 is always located on the side of the top plate 31 facing the bottom surface. The fastening bolt 42 penetrates the long waist-shaped hole 32 and the through hole 411 from bottom to top at the same time, and the fastening bolt 42 slides and fits along the length direction of the long waist-shaped hole 32. The fastening bolts 42 are threadedly connected with each other and pressed against the side of the pad 41 away from the top plate 31, thereby realizing the fixed installation of the machine body 6 on the support rod 3.

[0039] When the pipe cutter 2 needs to be fixedly installed, the staff uses an external trolley to support the pipe cutter 2 and moves it between the two support rods 3, so that the machine body 6 is located directly above the two support rods 3, and the staff can directly place the pipe cutter 2 on the two support rods 3. The staff repeats the above steps, so that the three pipe cutters 2 are spaced on the surface of the support rod 3 along the length direction of the support rod 3, and the spacing distance between the three pipe cutters 2 is pre-set. At the same time, the through hole 411 of the pad 41 is connected with the long waist-shaped hole 32 of the top plate 31 of the support rod 3, and then the staff passes the fastening bolt 42 from bottom to top through the long waist-shaped hole 32 and the through hole 411, and then the staff threadedly connects the fastening nut 43 with the fastening bolt 42 until the fastening nut 43 is pressed against the side of the pad 41 away from the top plate 31, so that the machine body 6 and the support rod 3 are fixedly connected.

[0040] When it is necessary to adjust the spacing distance of the pipe cutters 2, the staff loosens the fastening nut 43, thereby making the fastening bolt 42 active, and then the staff moves the pipe cutters 2 along the length direction of the long waist-shaped hole 32, and then adjusts the spacing between the pipe cutters 2, so that the fastening bolt 42 slides along the length direction of the long waist-shaped hole 32, and the long waist-shaped hole 32 can be used to guide the sliding direction of the pipe cutter 2. After completing the adjustment, the staff can tighten the fastening nut 43 again, thereby fixing the connection between the machine body 6 and the support rod 3.

The foot pedal 5 is electrically connected to the three pipe cutting machines 2, and the foot pedal 5 is used to control the three pipe cutting machines 2 to work in conjunction and cut the pipes simultaneously.

[0042] When it is necessary to cut the pipe, the staff clamps one pipe at the three pipe cutting machines 2 at the same time, and the length direction of the pipe is parallel to the length direction of the support rod 3. Then the staff steps on the pedal 5, and the pedal 5 is electrically connected to the three pipe cutting machines 2, so that the three pipe cutting machines 2 are started at the same time and cut the pipe at the same time, so that four fixing rods 12 can be cut at the same time (refer to Figure 1 As shown), the production efficiency of the fixing rod 12 is improved and the labor intensity of the staff is reduced.

[0043] Reference Figure 4 Specifically, the pipe cutting machine 2 also includes a cutting knife 7 for cutting pipes, a clamp 21 for clamping pipes, and a rotating mechanism movably installed between the cutting knife 7 and the machine body 6 for adjusting the cutting angle of the cutting knife 7.

The rotating block 813 is arranged in a cylindrical shape, one end of the rotating block 813 is placed on the end of the boss 63 away from the machine body 6, and the other end of the rotating block 813 extends in a direction away from the machine body 6. Specifically, the support plate 811 includes a support plate 811 connected between the rotating block 813 and the cutting blade 7, the support plate 811 is arranged in a vertical bending shape, one end of the support plate 811 is welded and fixed to the side wall of the rotating block 813, and the other end of the support plate 811 is connected to the cutting blade 7. A guide block 812 plug-fitting with the guide groove 641 is welded and fixed on the side of the support plate 811 facing the machine body 6, and the guide block 812 can slide and fit between the guide groove 641. The clamp fixing platform 82 is set in a cylindrical shape. One end of the clamp fixing platform 82 in the length direction is placed on the end of the rotating platform away from the boss 63 and is fixedly connected to the machine body 6. The other end of the clamp fixing platform 82 extends in the direction away from the rotating block 813. The end of the clamp fixing platform 82 away from the rotating block 813 is fixedly connected to the clamp 21, thereby supporting the clamp 21.

[0045] When it is necessary to adjust the cutting position of the cutting tool 7, the staff directly pushes the support plate 811 circumferentially, and then the support plate 811 drives the guide block 812 to slide, and then the guide block 812 slides and cooperates with the guide groove 641, thereby guiding the rotation direction of the support plate 811. At the same time, the support plate 811 drives the rotating block 813 to rotate in the same direction, so that the rotating block 813 and the fixture fixing table 82 rotate relative to each other, and then the cutting tool 7 and the fixture 21 rotate relative to each other, so that the cutting position of the cutting tool 7 can be adjusted.

[0046] Reference Figure 4 and Figure 5 , a receiving chamber 61 is provided in the machine body 6, and a rotating groove 62 is provided on the side wall of the machine body 6 in the horizontal direction, and the rotating groove 62 is connected to the internal receiving chamber 61; a through hole 631 is provided in the boss 63 in the vertical direction, which passes through the two opposite sides of the thickness direction, and the through hole 631 is connected to the receiving chamber 61.

A through hole 815 which passes through both the rotating block 813 and the insert block 814 is provided in the vertical direction of the rotating block 813, and the through hole 815 is connected to the receiving chamber.

[0047] Reference Figure 5 and Figure 6, the rotating mechanism also includes a fixing assembly for keeping the rotating block 813 fixed. Specifically, the fixing assembly includes a screw 831 fixedly connected between the fixture fixing platform 82 and the machine body 6, a fixing block 832 threadedly connected to the screw 831, and a handle 835 fixedly connected to the fixing block 832, and the fixing block 832 is used to fix the rotating block 813. One end of the screw 831 in the length direction is welded and fixed to the end of the fixture fixing platform 82 facing the rotating block 813, and the other end of the screw 831 in the length direction passes through the through hole 815 and the accommodating cavity 61 in sequence and is welded and fixed to the inner wall of the machine body 6. The screw 831 is located at the center of the rotating block 813, and the rotating block 813 can rotate relatively around the screw 831. The fixing block 832 is arranged in a cylindrical shape, and the length direction of the fixing block 832 is parallel to the length direction of the screw 831. The fixing block 832 is provided with first threaded holes 833 that penetrate through two opposite sides of the length direction thereof, and the first threaded holes 833 are threadedly connected to the screw rod 831, so that the fixing block 832 can be tightly pressed against one end of the insert block 814 located in the accommodating cavity 61. One end of the handle 835 is welded and fixed to the side wall of the fixing block 832, and the other end of the handle 835 extends in a direction away from the fixing block 832. At the same time, the handle 835 penetrates and extends outside the rotating groove 62, and the handle 835 can slide along the length direction of the rotating groove 62. The end of the side wall of the handle 835 away from the fixing block 832 is provided with anti-slip grooves 836 for contact by staff.

[0048] When the adjustment of the cutting position of the cutting knife 7 is completed, the staff holds the end of the handle 835 provided with the anti-slip groove 836 and rotates the handle 835 along the rotating groove 62, and then the handle 835 drives the fixed block 832 to rotate in the same direction, and utilizes the threaded connection between the fixed block 832 and the screw 831, and then the fixed block 832 can slide along the length direction of the screw 831, so that the fixed block 832 can be pressed against the insert block 814 of the rotating block 813, and then the fixture fixing platform 82 and the fixed block 832 are pressed against the rotating block 813 and the insert block 814 respectively, so that the rotating block 813 remains fixed, so that the cutting position of the cutting knife 7 remains stable in the later stage.

[0049] When the cutting position of the cutting knife 7 needs to be adjusted, the staff rotates the handle 835, and the handle 835 drives the fixed block 832 to rotate. The fixed connection between the fixed block 832 and the screw 831 is utilized, and the fixed block 832 slides along the length direction of the screw 831. At the same time, the fixed block 832 is separated from the insertion block 814, so that the rotating block 813 can rotate.

[0050] Reference Figure 5 and Figure 6The fixing block 832 is circumferentially provided with a plurality of second threaded holes 834 penetrating the opposite ends of the length direction thereof, and the plurality of second threaded holes 834 circumferentially surround the first threaded hole 833, and the diameter of the second threaded hole 834 is smaller than the first threaded hole 833. Preferably, in the present embodiment, the number of the second threaded holes 834 is three, and the three second threaded holes 834 are evenly spaced. Specifically, the fixing assembly further includes three tightening bolts 837 threadedly connected to the second threaded holes 834 and three tightening nuts 838 respectively threadedly connected to the bolts. The tightening bolt 837 penetrates the second threaded hole 834 from one end of the fixing block 832 away from the plug-in block 814 to one end of the fixing block 832 toward the plug-in block 814, and is threadedly connected to the second threaded hole 834. The tightening bolt 837 can be tightened to one end of the plug-in block 814 located in the accommodating cavity 61. The tightening nut 838 is threadedly connected to the tightening bolt 837, and the tightening nut 838 is always located between the end of the fixing block 832 away from the plug block 814 and the nut of the tightening bolt 837. The tightening nut 838 can be tightened against the end of the fixing block 832 away from the plug block 814, thereby keeping the tightening bolt 837 fixed.

[0051] The implementation principle of a pipe cutting processing system in the embodiment of the present application is:

[0052] When it is necessary to install the tightening bolt 837 and the tightening nut 838, the staff first threadably connects the tightening bolt 837 with the tightening nut 838 and passes through the tightening nut 838, and then the staff bolts the tightening bolt 837 to the fixing block 832 and passes through the fixing block 832 until the tightening nut 838 abuts against the end of the fixing block 832 away from the plug block 814, and then the staff tightens the tightening nut 838, and at the same time, part of the tightening bolt 837 extends out of the fixing block 832, thereby completing the installation of the tightening bolt 837 and the tightening nut 838.

[0053] When the cutting angle of the cutting blade 7 is adjusted, the staff member rotates the handle 835, and the handle 835 drives the fixed block 832 to rotate in the same direction. The fixed block 832 rotates and slides along the length direction of the screw rod 831, and the tightening bolt 837 is pressed against the end of the plug block 814 away from the rotating block 813, thereby fixing the rotating block 813. The tightening bolt 837 is used to reduce the contact between the fixed block 832 and the plug block 814, and reduce the wear of the end of the fixed block 832 facing the plug block 814. At the same time, the tightening bolt 837 can reduce the rotation displacement of the fixed block 832 and can effectively tighten the plug block 814.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
