Description

Technical Field

[0001] The present application relates to the technical field of tube processing, and in particular to a tube cutting device. Background Art

[0002] In order to protect the metal rod, a hose is put on the metal rod. In order to improve the installation convenience of the hose and the metal rod, the hose needs to be cut open and then the metal rod is inserted into the hose through the cut slit of the hose.

[0003] The existing method is that the staff holds a blade by hand, places the blade against the end face of the hose, and then moves the blade along the axial direction of the hose to cut the hose. This cutting method is prone to cause the blade to deflect, thereby causing the cut seam of the hose to deflect, reducing the cutting quality of the hose, and therefore needs further improvement. Utility Model Content

[0004] In order to reduce the possibility of deviation of the hose cut seam, the present application provides a tube cutting device.

[0005] The present application provides a pipe cutting device that adopts the following technical solution:

[0006] A pipe cutting device comprises a guide seat, wherein the guide seat has a guide groove for a hose to slide through, and the guide seat is provided with a blade with one end extending to the guide groove for cutting the hose.

[0007] By adopting the above technical solution, when the hose needs to be cut, the end of the hose is inserted into the guide groove. When the end face of the hose abuts against the blade, the hose is continuously pushed, so that the hose can be quickly cut and the possibility of deviation of the hose cut is effectively reduced.

[0008] Preferably, the guide seat is provided with a limiting knife groove connected to the guide groove, and the blade is inserted in the limiting knife groove.

[0009] By adopting the above technical solution, the blade is inserted into the limiting knife groove, and the limiting knife groove has a limiting effect on the blade, effectively reducing the possibility of the blade being deflected, thereby improving the straightness of the hose cutting seam.

[0010] Preferably, the notch of the limiting knife groove extends to the outer side wall of the guide seat, the blade penetrates to form a limiting hole, and the guide seat is provided with a limiting member inserted in the limiting hole.

[0011] By adopting the above technical solution, when installing the blade, the blade is inserted into the notch of the limiting blade groove so that one end of the blade extends into the guide groove, and then the blade and the guide seat are fixed by inserting the limiting piece into the limiting hole.

[0012] Preferably, the outer side wall of the guide seat is provided with a first threaded hole connected to the limiting knife groove, and the limiting member includes a limiting bolt threadedly connected to the first threaded hole, and the limiting bolt is passed through the limiting hole.

[0013] By adopting the above technical solution, when installing the blade, the blade is inserted into the notch of the limiting knife groove so that one end of the blade extends into the guide groove, and the first threaded hole corresponds to the limiting hole. The limiting bolt is tightened so that the limiting bolt passes through the limiting hole, thereby fixing the blade and the guide seat.

[0014] Preferably, the outer wall of the guide seat is provided with a through hole connected to the limiting knife groove, the limiting member includes a limiting rod slidably arranged in the through hole, and the guide seat is provided with an elastic member inserted into the limiting hole which forces the limiting rod to slide toward the direction close to the limiting knife groove under normal circumstances.

[0015] By adopting the above technical solution, when installing the blade, a force is first applied to the limit rod so that the limit rod slides in the direction away from the limit knife groove, providing avoidance space for the blade. At this time, the elastic member undergoes elastic deformation and has elastic potential energy. The blade is inserted into the notch of the limit knife groove so that one end of the blade extends into the guide groove, and the through hole corresponds to the limit hole. After the force applied to the limit rod is removed, the elastic member forces the limit rod to slide in the direction close to the limit knife groove and be inserted into the limit hole, thereby fixing the blade and the guide seat.

[0016] Preferably, the end of the limiting rod away from the limiting knife groove is fixedly connected to a force plate, and the elastic member is a spring, one end of the spring is fixedly connected to the outer side wall of the guide seat, and the other end of the spring is fixedly connected to the force plate.

[0017] By adopting the above technical solution, the spring has the characteristics of good elastic potential energy and is easy to install.

[0018] Preferably, the end of the limiting rod has a guide surface for the end of the blade to abut against so as to force the limiting rod to slide toward the outside of the guide seat.

[0019] By adopting the above technical solution, when installing the blade, the blade is directly inserted into the notch of the limiting knife groove, so that one end of the blade first abuts against the guide surface of the limiting rod, and then the blade is pushed forward, forcing the limiting rod to slide toward the outside of the guide seat. At this time, the elastic member undergoes elastic deformation and has elastic potential energy. When the end of the blade extends into the guide groove and the through hole corresponds to the limiting hole, the elastic member forces the limiting rod to slide toward the direction close to the limiting knife groove and be inserted into the limiting hole, thereby fixing the blade and the guide seat.

[0020] Preferably, the other end of the blade protrudes out from the guide seat.

[0021] By adopting the above technical solution, the convenience of disassembling and assembling the blade is improved.

[0022] Preferably, the guide seat / blade is detachably connected to a protective scabbard which is sleeved on the blade.

[0023] By adopting the above technical solution, the protective scabbard covers the blade exposed from the guide seat, thereby improving the usability and installation.

[0024] Preferably, the end surface of the protective scabbard is fixedly connected with a mounting ring plate, and the mounting ring plate is penetrated by a protective bolt which is threadedly connected to the guide seat.

[0025] By adopting the above technical solution, a mounting ring plate is added to provide a mounting carrier for the protective bolt, and a detachable connection between the protective scabbard and the guide seat is achieved through the protective bolt.

[0026] In summary, the utility model has the following beneficial effects:

[0027] 1. When the hose needs to be cut, insert the end of the hose into the guide groove. When the end face of the hose abuts against the blade, continue to push the hose to quickly cut the hose and effectively reduce the possibility of the hose cutting seam being deflected;

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Embodiment 1:

[0038] The present application embodiment discloses a tube cutting device, referring to Figure 1 , including a guide seat 1, the guide seat 1 has a guide groove 11 for the hose to slide through. In this embodiment, the guide groove 11 is opened on the upper end surface of the guide seat 1, the length direction of the guide groove 11 is parallel to the length direction of the guide seat 1, and the two end notches of the guide groove 11 extend on both sides of the guide seat 1 respectively, and the diameter of the guide groove 11 is adapted to the outer diameter of the hose.

[0039] Reference Figure 2 , Figure 3 The lower end surface of the guide seat 1 is provided with a limiting knife groove 12 connected to the inner wall of the bottom of the guide groove 11. The guide seat 1 is provided with a blade 2 inserted in the limiting knife groove 12. The upper part of the blade 2 extends to the guide groove 11 to cut the hose. The lower part of the blade 2 protrudes from the lower end surface of the guide seat 1. The blade plane of the blade 2 is parallel to the axial direction of the guide groove 11, and the upper part of the blade 2 has an inclined blade 21.

[0040] Reference Figure 2 , Figure 3 The blade 2 has a limiting hole 22 formed through the blade body, and the guide seat 1 is provided with a limiting member 4 inserted in the limiting hole 22. Specifically, the outer wall of the guide seat 1 is provided with a first threaded hole 13 connected to the limiting knife groove 12, and the limiting member 4 is a limiting bolt 41 threadedly connected to the first threaded hole 13, and the limiting bolt 41 is a countersunk bolt, and the limiting bolt 41 is inserted in the limiting hole 22.

[0041] Reference Figure 1 , Figure 2 The guide seat 1 or the blade 2 is detachably connected with a protective scabbard 3 mounted on the blade 2. In the present embodiment, the guide seat 1 is detachably connected with a protective scabbard 3 mounted on the blade 2. Specifically, the upper end surface of the protective scabbard 3 is fixedly connected with a mounting ring plate 31, and the mounting ring plate 31 is penetrated by a protective bolt 32 which is threadedly connected to the lower end surface of the guide seat 1.

[0042] When installing the blade 2, insert the blade 2 into the limiting knife groove 12 on the lower end surface of the guide seat 1, so that one end of the blade 2 extends into the guide groove 11, and the first threaded hole 13 corresponds to the limiting hole 22, and tighten the limiting bolt 41 so that the limiting bolt 41 passes through the limiting hole 22 to fix the blade 2 and the guide seat 1, and then put the protective scabbard 3 on the blade 2 exposed from the guide seat 1, and finally lock the protective bolt 32.

[0043] The implementation principle of a tube cutting device in an embodiment of the present application is: when it is necessary to cut a hose, the end of the hose is inserted into the guide groove 11. When the end face of the hose abuts against the blade 21 of the blade 2, the hose is continuously pushed, and the blade 21 of the blade 2 can quickly cut the hose and effectively reduce the possibility of deviation of the hose cut.

[0044] Embodiment 2:

[0045] The difference from Example 1 is that, referring to Figure 4 A mounting hole 23 is formed through the lower part of the blade 2, and a second threaded hole 33 connected to the inner cavity of the protective scabbard 3 is formed on the outer wall of the protective scabbard 3. The protective scabbard 3 is provided with a mounting bolt 34 threadedly connected to the second threaded hole 33. The mounting bolt 34 is a countersunk bolt. The mounting bolt 34 is passed through the mounting hole 23, and the upper end surface of the protective scabbard 3 abuts against the lower end surface of the guide seat 1.

[0046] The implementation principle of the embodiment of the present application is: after the blade 2 and the protective scabbard 3 are fixed, the blade 2 is inserted into the limiting knife groove 12 on the lower end surface of the guide seat 1, and the blade 2 is fixed and installed by the limiting bolt 41.

[0047] Embodiment 3:

[0048] The difference from Example 1 is that, referring to Figure 5 The outer wall of the guide seat 1 is provided with a through hole 14 connected to the limiting knife groove 12. The limiting member 4 is a limiting rod 42 that is slidably inserted into the through hole 14. The end of the limiting rod 42 away from the limiting knife groove 12 is fixedly connected to a force plate 43. The guide seat 1 is provided with an elastic member inserted into the limiting hole 22 to force the limiting rod 42 to slide toward the limiting knife groove 12 under normal conditions. Specifically, the elastic member is a spring 44. One end of the spring 44 is fixedly connected to the outer wall of the guide seat 1, and the other end of the spring 44 is fixedly connected to the force plate 43. The end of the limiting rod 42 has a guide surface 45 for the upper end surface of the blade 2 to abut against so as to force the limiting rod 42 to slide toward the outer side of the guide seat 1.

[0049] The implementation principle of the embodiment of the present application is: when installing the blade 2, directly insert the blade 2 from the notch of the limiting knife groove 12, so that the upper end of the blade 2 first abuts against the guide surface 45 of the limiting rod 42, and then continue to push the blade 2, forcing the limiting rod 42 to slide toward the outside of the guide seat 1. At this time, the spring 44 undergoes elastic deformation and has elastic potential energy. When the end of the blade 2 extends into the guide groove 11 and the through hole 14 and the limiting hole 22 correspond, the spring 44 forces the limiting rod 42 to slide toward the direction close to the limiting knife groove 12 and be inserted into the limiting hole 22, thereby realizing the rapid fixed installation of the blade 2 and the guide seat 1.

[0050] 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.
