[0002] The steel wire skeleton hose is composed of inner and outer rubber layers and a skeleton layer. The skeleton layer is made of steel wire to improve the performance of the hose. When assembling the steel wire skeleton hose, it is necessary to cut the steel wire skeleton hose.

[0003] However, the cutting of wire skeleton hoses generally adopts manual fixing of the hose, and a toothed saw is used for one cut or a toothless saw is used for multiple cuts. Due to the large diameter of the hose and the steel wire inside, the cut surface of the hose cannot be kept perpendicular to the axis of the hose, is uneven, and the steel wire is exposed during cutting. This affects the assembly and crimping of the subsequent hose assembly, reduces the performance of the hose assembly, and does not meet people's use needs. For this reason, we propose an automatic ring cutting device for wire skeleton hoses. Summary of the invention

At the same time, the sliding of the active orifice plate drives the connecting orifice plate to slide along the outer wall of the connecting limit rod through the active pin, and then the sliding of the connecting orifice plate drives the driven orifice plate to slide along the outer wall of the driven limit rod through the driven pin, and the sliding of the driven orifice plate drives the second roller to fit the outer wall of the wire skeleton hose. The first roller and the second roller slide relative to each other, thereby ensuring that the cutting surface of the hose can remain perpendicular to the axial direction of the hose, so that after the wire skeleton hose is cut, the hose is neat and there is no exposed wire, which effectively ensures the subsequent assembly and buckling of the hose assembly and improves the performance of the hose assembly.

[0008] Preferably, a handle is fixedly connected to the outer wall of the positioning frame, and an observation window is provided on the outer wall of the working frame. When working, the handle is provided to facilitate the transportation and transfer of the annular cutting device, and the observation window is provided to facilitate the staff to clearly observe the cutting area of ​​the wire skeleton hose.

[0009] Preferably, the working frame and the positioning frame are both arc-shaped in appearance, and the sliding trajectories of the active orifice plate, the connecting orifice plate and the driven orifice plate all move along the radial straight line of the positioning frame. During operation, by setting the arc-shaped working frame and the positioning frame, the positioning frame can be directly placed in the cutting area.

[0010] Preferably, the second roller is provided with two groups, the first roller and the two groups of second rollers are distributed at equal angles around the center of the positioning frame, the active roller, the first roller and the second roller are located on the same circumference, and during operation, the active orifice plate slides through the active pin to drive the connecting orifice plate to slide along the outer wall of the connecting limit rod, and then the connecting orifice plate slides through the driven pin to drive the driven orifice plate to slide along the outer wall of the driven limit rod, and the sliding of the driven orifice plate drives the second roller to fit against the outer wall of the wire skeleton hose, and the relative sliding of the first roller and the second roller ensures that the cutting surface of the hose can remain perpendicular to the axial direction of the hose.

[0011] Preferably, an adjusting screw penetrates the inner wall of the working frame, one end of the adjusting screw is fixedly connected to an adjusting knob, the outer wall of the adjusting screw is threadedly connected to an adjusting slider, the outer wall of the adjusting slider is screwed to a connecting support rod, one end of the connecting support rod is screwed to an adjusting base rotatably connected to the inner wall of the working frame, the outer wall of the adjusting base is fixedly connected to the outer wall of the cutting motor, when working, the adjusting knob rotates to drive the adjusting slider to slide along the inner wall of the working frame through the adjusting screw, the sliding of the adjusting slider drives the adjusting base to rotate through the connecting support rod, the rotation of the adjusting base drives the toothless saw disk at one end of the cutting motor to contact the wire skeleton hose, and then, the cutting motor works to drive the toothless saw disk to rotate, thereby cutting the wire skeleton hose.

[0012] Preferably, the adjustment base forms a rotating structure with the working frame through the adjustment slider and the connecting support rod, and the toothless saw disk is parallel to the working frame. During operation, the adjustment slider slides through the connecting support rod to drive the adjustment base to rotate, and the rotation of the adjustment base drives the toothless saw disk at one end of the cutting motor to contact the wire skeleton hose. By setting the toothless saw disk parallel to the working frame, it is ensured that the cutting surface of the hose can always remain perpendicular to the axis of the hose.

[0013] Preferably, the side wall of the positioning frame is fixedly connected with a rotating guide rail, the outer wall of the rotating guide rail is embedded with a rotating sleeve, the bottom end of the rotating sleeve is fixedly connected to the mounting base, the top of the rotating sleeve is fixedly connected to the switching frame, the inner wall of the switching frame is penetrated by a switching screw, the top of the switching screw is fixedly connected with a switching knob, the outer wall of the switching screw is threadedly connected with a lifting slider, and the outer wall of the lifting slider is fixedly connected with a clamping column, and a clamping groove is provided at the connecting part of the rotating guide rail and the clamping column. During operation, when the length of the wire skeleton hose is long or the weight is heavy, it is more difficult for the active roller to drive the wire skeleton hose to rotate. The staff installs the rotating sleeve on the mounting base through bolts, and then turns the switching knob. The rotation of the switching knob drives the lifting slider to slide through the switching screw, and the sliding of the lifting slider drives the clamping column and the clamping slot to move away, so that the rotating guide rail and the rotating sleeve can rotate relative to each other.

During operation, by setting the rotating sleeve and the mounting base as detachable structures, cutting operations on different types of steel wire skeleton hoses can be achieved. By setting the rotating guide rail with a "T"-shaped cross-section, it is beneficial to improve the rotation stability of the positioning frame, and avoid shaking of the positioning frame during rotation, which causes the cutting surface of the hose to be unable to remain perpendicular to the axis of the hose.

[0015] Preferably, the central axis of the clamping column coincides with the diameter of the rotating guide rail, and the rotating guide rail forms a positioning structure with the rotating sleeve through the clamping column and the clamping slot. During operation, the switching knob rotates to drive the lifting slider to slide through the switching screw, and the sliding of the lifting slider drives the clamping column and the clamping slot to engage, thereby realizing the synchronous movement operation of the rotating guide rail and the rotating sleeve.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting an active orifice plate and a driven orifice plate, the active orifice plate slides to drive the first roller to fit the outer wall of the steel wire skeleton hose. At the same time, the active orifice plate slides through the active pin to drive the connecting orifice plate to slide along the outer wall of the connecting limit rod, and then the connecting orifice plate slides through the driven pin to drive the driven orifice plate to slide along the outer wall of the driven limit rod. The driven orifice plate slides to drive the second roller to fit the outer wall of the steel wire skeleton hose. The first roller and the second roller slide relative to each other, thereby ensuring that the cut surface of the hose can remain perpendicular to the axial direction of the hose, so that after the steel wire skeleton hose is cut, the hose is neat and there is no exposed wire, which effectively ensures the subsequent assembly and crimping of the hose assembly and improves the performance of the hose assembly.

[0018] 2. By setting a connecting hole plate, the sliding of the connecting hole plate drives the working base to slide synchronously. The sliding of the working base drives the active roller at one end of the rotating motor to fit the outer wall of the wire skeleton hose. Then, the rotating motor drives the active roller and the wire skeleton hose to roll relative to each other, thereby driving the wire skeleton hose to rotate 360° evenly, avoiding the uneven cutting surface of the wire skeleton hose due to the uneven rotation speed of the wire skeleton hose.

[0019] 3. By setting an adjustment base, the adjustment knob is rotated to drive the adjustment slider to slide along the inner wall of the working frame through the adjustment screw. The adjustment slider slides through the connecting support rod to drive the adjustment base to rotate. The rotation of the adjustment base drives the toothless saw disk at one end of the cutting motor to contact the wire skeleton hose. Then, the cutting motor works to drive the toothless saw disk to rotate and cut the wire skeleton hose.

[0020] 4. By setting the clamping column and the clamping slot, when the wire skeleton hose is long or heavy, it is difficult for the active roller to drive the wire skeleton hose to rotate. The staff installs the rotating sleeve on the mounting base through bolts, and then turns the switching knob. The switching knob rotates to drive the lifting slider to slide through the switching screw. The sliding of the lifting slider drives the clamping column and the clamping slot to move away, so that the rotating guide rail and the rotating sleeve can rotate relative to each other. The rotation of the active roller will drive the positioning frame to rotate with the central axis of the wire skeleton hose, so as to realize the quick cutting operation of the wire skeleton hose with a long length or heavy weight.

When working, the handle 5 is provided to facilitate the transportation and transfer of the annular cutting device, and the observation window 6 is provided to facilitate the staff to clearly observe the cutting area of ​​the wire skeleton hose.

[0039] For further information, see Figures 4 to 7 The working frame 1 and the positioning frame 2 are both arc-shaped in shape, and the sliding tracks of the active orifice plate 204, the connecting orifice plate 207 and the driven orifice plate 210 all move along the radial straight line of the positioning frame 2. When working, by setting the arc-shaped working frame 1 and the positioning frame 2, the positioning frame 2 can be directly placed in the cutting area.

[0040] For further information, see Figure 4 , Figures 5 to 8 The second roller 213 is provided with two groups, the first roller 206 and the two groups of second rollers 213 are distributed at equal angles about the center of the positioning frame 2, the active roller 402, the first roller 206 and the second roller 213 are located on the same circumference, when working, the active orifice plate 204 slides through the active pin 208 to drive the connecting orifice plate 207 to slide along the outer wall of the connecting limit rod 209, and then the connecting orifice plate 207 slides through the driven pin 211 to drive the driven orifice plate 210 to slide along the outer wall of the driven limit rod 212, the driven orifice plate 210 slides and drives the second roller 213 to fit the outer wall of the steel wire skeleton hose, and the first roller 206 and the second roller 213 slide relative to each other, thereby ensuring that the cutting surface of the hose can remain perpendicular to the axial direction of the hose.

[0041] For further information, see Figure 4 and Fig. 9 The inner wall of the working frame 1 is penetrated by an adjusting screw 7, one end of the adjusting screw 7 is fixedly connected with an adjusting knob 701, the outer wall of the adjusting screw 7 is threadedly connected with an adjusting slider 702, the outer wall of the adjusting slider 702 is screwed with a connecting support rod 703, one end of the connecting support rod 703 is screwed with an adjusting base 704 rotatably connected to the inner wall of the working frame 1, the outer wall of the adjusting base 704 is fixedly connected to the outer wall of the cutting motor 3. When working, the adjusting knob 701 rotates through the adjusting screw 7 to drive the adjusting slider 702 to slide along the inner wall of the working frame 1, the adjusting slider 702 slides through the connecting support rod 703 to drive the adjusting base 704 to rotate, and the rotation of the adjusting base 704 drives the toothless saw disk 301 at one end of the cutting motor 3 to contact the wire skeleton hose, and then, the cutting motor 3 works to drive the toothless saw disk 301 to rotate, and the wire skeleton hose is cut.

[0042] For further information, see Figure 4 and Fig. 9The adjusting base 704 forms a rotating structure with the working frame 1 through the adjusting slider 702 and the connecting support rod 703. The toothless saw disk 301 is parallel to the working frame 1. When working, the adjusting slider 702 slides through the connecting support rod 703 to drive the adjusting base 704 to rotate. The adjusting base 704 rotates to drive the toothless saw disk 301 at one end of the cutting motor 3 to contact the wire skeleton hose. By setting the toothless saw disk 301 parallel to the working frame 1, it is ensured that the cutting surface of the hose can always remain perpendicular to the axis of the hose.

[0043] For further information, see Figures 10 to 12 The side wall of the positioning frame 2 is fixedly connected with a rotating guide rail 8, the outer wall of the rotating guide rail 8 is embedded with a rotating sleeve 801, the bottom end of the rotating sleeve 801 is fixedly connected with a mounting base 802, the top of the rotating sleeve 801 is fixedly connected with a switching frame 803, the inner wall of the switching frame 803 is penetrated by a switching screw 804, the top of the switching screw 804 is fixedly connected with a switching knob 805, the outer wall of the switching screw 804 is threadedly connected with a lifting slider 806, the outer wall of the lifting slider 806 is fixedly connected with a clamping column 807, and a clamping groove 808 is provided at the connection portion between the rotating guide rail 8 and the clamping column 807. When working, when the length of the steel wire skeleton hose is longer, When the wire skeleton hose is long or heavy, it is difficult for the active roller 402 to drive the steel wire skeleton hose to rotate. The staff installs the rotating sleeve 801 on the mounting base 802 by bolts, and then the staff turns the switching knob 805. The switching knob 805 rotates to drive the lifting slider 806 to slide through the switching screw 804. The sliding of the lifting slider 806 drives the clamping column 807 and the clamping slot 808 to move away, so that the rotating guide rail 8 and the rotating sleeve 801 can rotate relative to each other. The rotation of the active roller 402 will drive the positioning frame 2 to rotate about the central axis of the steel wire skeleton hose, thereby realizing the rapid cutting operation of the steel wire skeleton hose that is long or heavy.

[0044] For further information, see Figures 10 to 12 The shapes of the rotating guide rail 8 and the rotating sleeve 801 are both arc-shaped, the centers of the rotating guide rail 8 and the rotating sleeve 801 coincide with the center of the positioning frame 2, the rotating sleeve 801 and the mounting base 802 are detachable structures, and the cross-section of the rotating guide rail 8 is "T"-shaped. During operation, by setting the rotating sleeve 801 and the mounting base 802 as detachable structures, the cutting operation of different types of steel wire skeleton hoses can be realized. By setting the rotating guide rail 8 with a "T"-shaped cross-section, it is beneficial to improve the rotation stability of the positioning frame 2, and avoid the positioning frame 2 from shaking during rotation, which causes the hose cutting surface to be unable to remain perpendicular to the hose axis.

[0045] For further information, see Fig.12The central axis of the clamping column 807 coincides with the diameter of the rotating guide rail 8. The rotating guide rail 8 forms a positioning structure with the rotating sleeve 801 through the clamping column 807 and the clamping groove 808. When working, the switching knob 805 rotates to drive the lifting slider 806 to slide through the switching screw 804. The sliding of the lifting slider 806 drives the clamping column 807 and the clamping groove 808 to engage with each other, thereby realizing the synchronous movement operation of the rotating guide rail 8 and the rotating sleeve 801.

[0046] The working principle of the present invention is as follows: when using the automatic circular cutting device for the steel wire skeleton hose, first, the staff places the steel wire skeleton hose inside the working frame 1, then performs a center positioning operation on the steel wire skeleton hose, and the staff rotates the hand wheel 202, and the hand wheel 202 rotates to drive the active plate 203 to slide along the diameter direction of the working frame 1 through the positioning screw 201, and the active plate 203 slides to drive the active orifice plate 204 to slide along the outer wall of the active limit rod 205, and the active orifice plate 204 slides to drive the first roller 206 to fit the outer wall of the steel wire skeleton hose, and at the same time, the active orifice plate 204 slides The active pin 208 drives the connecting hole plate 207 to slide along the outer wall of the connecting limit rod 209, and then the connecting hole plate 207 slides through the driven pin 211 to drive the driven hole plate 210 to slide along the outer wall of the driven limit rod 212. The sliding of the driven hole plate 210 drives the second roller 213 to fit the outer wall of the steel wire skeleton hose. The first roller 206 and the second roller 213 slide relative to each other, thereby ensuring that the cut surface of the hose can remain perpendicular to the axial direction of the hose, so that after the steel wire skeleton hose is cut, the hose is neat and there is no exposed wire, which effectively ensures the subsequent assembly and crimping of the hose assembly and improves the performance of the hose assembly.

[0047] At the same time, the connecting hole plate 207 slides to drive the working base 4 to slide synchronously, and the sliding of the working base 4 drives the active roller 402 at one end of the rotating motor 401 to fit the outer wall of the steel wire skeleton hose. Then, the rotating motor 401 works to drive the active roller 402 and the steel wire skeleton hose to roll relative to each other, thereby driving the steel wire skeleton hose to rotate 360° evenly, avoiding the uneven cutting surface of the steel wire skeleton hose due to the uneven rotation speed of the steel wire skeleton hose.

[0048] Next, the wire skeleton hose is cut by the staff member turning the adjusting knob 701. The adjusting knob 701 rotates through the adjusting screw 7 to drive the adjusting slider 702 to slide along the inner wall of the working frame 1. The adjusting slider 702 slides through the connecting support rod 703 to drive the adjusting base 704 to rotate. The adjusting base 704 rotates to drive the toothless saw disk 301 at one end of the cutting motor 3 to contact the wire skeleton hose. Then, the cutting motor 3 works to drive the toothless saw disk 301 to rotate, and the wire skeleton hose is cut.

[0049] Finally, when the steel wire skeleton hose is long or heavy, it is difficult for the active roller 402 to drive the steel wire skeleton hose to rotate. The staff installs the rotating sleeve 801 on the mounting base 802 by bolts, and then the staff turns the switching knob 805. The switching knob 805 rotates to drive the lifting slider 806 to slide through the switching screw 804. The sliding of the lifting slider 806 drives the clamping column 807 and the clamping slot 808 to move away, so that the rotating guide rail 8 and the rotating sleeve 801 can rotate relative to each other. The rotation of the active roller 402 will drive the positioning frame 2 to rotate about the central axis of the steel wire skeleton hose, thereby realizing the rapid cutting operation of the steel wire skeleton hose that is long or heavy.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
