[0002] As a common basic component in the field of liquid transmission, tubular items require cutting equipment to cut long strips of tubular components during the production and processing process to obtain pipe sections that meet the customer's specified size requirements and satisfy the needs of actual application scenarios.

[0003] However, existing mainstream pipe cutting equipment still has obvious technical defects in actual use: on the one hand, the inclination angle of the pipe fitting cut needs to be flexibly adjusted according to the specific needs of customers, but the cutting angle of existing pipe cutting equipment is mostly a fixed structural design, which cannot adapt to the diverse cutting angle processing needs, resulting in limited applicability and poor versatility; on the other hand, the pipe fitting lacks an effective positioning constraint structure when placed at the cutting station, which is prone to positional deviation, resulting in excessive deviation in cutting size, affecting the cutting accuracy of pipe sections, and making it difficult to ensure product quality stability.

[0004] Therefore, it is necessary to provide a new pipe cutting device with a sliding track and a rotating blade holder to solve the above-mentioned technical problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] First embodiment: Please refer to the following: Figures 1-3The pipe cutting device, featuring a sliding track and a rotating blade holder, includes: a lower fixed plate 12 and an upper fixed plate 2 positioned above it. Two fixed supports 9 are bolted between the two for stability. Four foot pads are bolted to the bottom of the lower fixed plate 12, and a pipe fitting fixing seat 11 is bolted to the top of the lower fixed plate 12. The pipe fitting fixing seat 11 has a pipe groove, within which a pipe fitting 10 is placed. The groove engages with the pipe fitting 10, thus restraining it and preventing it from shifting during cutting. Two blade grooves with a certain angle are formed on the pipe fitting fixing seat 11, dividing it into three sections. A first telescopic cylinder 1 is fixedly mounted on the upper fixed plate 2, its output shaft passing through and slidably connected to the upper fixed plate 2. The lower fixed plate 12... A tool holder fixing plate 4 is provided between the upper fixing plate 2 and the tool holder fixing plate 4. The output shaft of the first telescopic cylinder 1 is fixedly connected to the tool holder fixing plate 4. Two guide columns 3 are fixedly installed on the top of the tool holder fixing plate 4. The top ends of the two guide columns 3 pass through the upper fixing plate 2 and are slidably connected to it to improve stability. Two waist holes are opened on the tool holder fixing plate 4. Threaded columns are provided in the two waist holes. Blade fixing seats 5 are threadedly installed at the bottom of the two threaded columns. Anti-rotation rings 18 are threadedly fitted on the two threaded columns. The tops of the two anti-rotation rings 18 abut against the tool holder fixing plate 4. By tightening the anti-rotation rings 18, the threaded columns cannot be easily rotated. Thus, the cutting angle of the blade 6 can be adjusted by rotating the threaded columns. Blade mounting slots are opened at the bottom of the two blade fixing seats 5. Blade 6 is fixedly installed in the two blade mounting slots by bolts. The two blades 6 are respectively adapted to the two blade slots.

[0019] In this embodiment, in order to ensure the smooth extension and retraction of the output shaft of the first telescopic cylinder 1, two bearing holes are provided on the upper fixed plate 2. Linear bearings are provided in both bearing holes. Two guide posts 3 pass through the two linear bearings and fit against the inner wall of the corresponding linear bearings. Bearing pressure plates are fixedly sleeved on both linear bearings. Both bearing pressure plates are fixedly connected to the top of the upper fixed plate 2 by bolts.

[0020] In this embodiment, in order to achieve pressing and limiting of the pipe fitting 10 from above the pipe fitting fixing seat 11, two connecting rods 8 are provided in each of the two waist holes. The top of each of the four connecting rods 8 is fixedly installed with a screw head. The bottom of each of the four screw heads abuts against the tool holder fixing plate 4. Each of the four connecting rods 8 is fitted with a pressing tube rubber 7. The bottom of each of the four pressing tube rubber 7 is provided with a nut groove. The bottom of each of the four connecting rods 8 is fixedly installed with a threaded rod. The bottom of each of the four threaded rods extends into the corresponding nut groove, and each of the four nut grooves is provided with a nut. The top of each of the four nuts is respectively attached to the top inner wall of the four nut grooves. Each of the four threaded rods passes through the corresponding nut and is screwed into the corresponding nut. When the first telescopic cylinder 1 is activated, the pressing tube rubber 7 descends and first contacts the top of the pipe fitting fixing seat 11. At this time, the output shaft of the first telescopic cylinder 1 continues to extend, so that the pressing tube rubber 7 is compressed by force, thereby achieving pressing and limiting of the pipe fitting 10 and preventing it from jumping out of the pipe groove.

[0021] In this embodiment When cutting, first install the pipe fitting fixing seat 11 with the corresponding tilt angle knife groove according to the requirements. Then the operator places the pipe fitting 10 to be cut into the pipe groove of the pipe fitting fixing seat 11. The pipe groove provides initial support and positioning for the pipe fitting 10. Subsequently, the cutting angle of the pipe fitting 10 is adjusted according to customer requirements. First, the anti-rotation rings 18 corresponding to the threaded columns in the two waist holes are loosened to release the fixed constraint between the threaded columns and the tool holder fixing plate 4. Since there are two waist holes on the tool holder fixing plate 4, the threaded columns can slide along the length of the waist holes. At the same time, the blade fixing seat 5 can rotate around its own axis with the threaded columns, thereby driving the blade 6 to move and rotate synchronously. By adjusting the sliding position and rotation angle of the two blade fixing seats 5 in the waist holes, the two blades 6 are precisely aligned with the two tool grooves on the pipe fitting fixing seat 11, and the cutting edge of the blade 6 is consistent with the inclination angle of the tool groove. After the adjustment is completed, the anti-rotation rings 18 are tightened to fix the angle of the blade 6 and meet the processing requirements of diverse cutting angles. Then, the first telescopic cylinder 1 is activated, and its output shaft extends downward, driving the knife holder fixing plate 4, which is fixedly connected to it, to move smoothly downward along the axial direction of the guide column 3. During this process, the two blades 6 at the bottom of the knife holder fixing plate 4 move downward synchronously with the knife holder fixing plate 4. At the same time, multiple pressure tube rubbers 7 also descend. Among them, the pressure tube rubbers 7 first contact the pipe fitting fixing seat 11 and are compressed by force. Then, the blades 6 and the knife groove on the pipe fitting fixing seat 11 contact the pipe fitting 10, and then the positioning pipe fitting 10 is cut. At the same time, the pressure tube rubbers 7 always maintain the pressure on the pipe fitting 10, effectively preventing the pipe fitting 10 from moving under the action of cutting force, and ensuring the cutting dimension accuracy. After the cutting is completed, the output shaft of the first telescopic cylinder 1 retracts, driving the knife holder fixing plate 4 and the blade 6 to return to the initial position. The operator can then take out the cut pipe section product and complete one cutting cycle.

[0022] Compared with related technologies, the pipe cutting device with sliding track and rotating blade holder provided by this utility model has the following advantages: I. This utility model has a dual adjustment structure of sliding waist hole + rotating blade fixing seat 5, and with a replaceable tube fixing seat 11 with angled knife groove, it can quickly adjust the cutting angle of the blade 6 to meet the processing needs of different inclined cutting, and has strong versatility. Second, this utility model effectively avoids the deviation and movement of the pipe fitting 10 during cutting by the dual constraint of the initial positioning of the pipe groove and the elastic pressing of the pipe pressure rubber 7. Combined with the smooth movement of the tool holder fixing plate 4 guaranteed by the guide column 3 and the linear bearing, the cutting size accuracy is greatly improved.

[0023] Second embodiment: Based on the pipe cutting device with a sliding track and a rotating blade holder provided in the first embodiment of this application, the second embodiment of this application proposes another pipe cutting device with a sliding track and a rotating blade holder. The second embodiment is merely a further embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0024] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figure 4 The pipe cutting device with sliding rails and rotating blade holder also includes two mounting protrusions 13. The two mounting protrusions 13 are respectively fixedly installed on the opposite sides of the two fixed supports 9. A second telescopic cylinder 14 is fixedly installed on each of the two mounting protrusions 13. The output shafts of the two second telescopic cylinders 14 pass through the corresponding mounting protrusions 13 and are slidably connected to the corresponding mounting protrusions 13. A rodless cylinder 15 is fixedly installed on the output shafts of the two second telescopic cylinders 14. A connecting piece 16 is fixedly installed on the slider of the two rodless cylinders 15. A push rod 17 is installed on each of the two connecting pieces 16.

[0026] Both connecting pieces 16 have threaded holes, and threaded heads are threaded into both threaded holes. The ends of the two threaded heads that are close to each other are fixedly connected to the two push rods 17 respectively.

[0027] In this embodiment After cutting, since multiple pipe segments are in the pipe groove and difficult to pry out by hand, the output shafts of the two second telescopic cylinders 14 are first activated to extend, causing the rodless cylinder 15 to descend with the push rod 17. Eventually, the two push rods 17 are aligned horizontally with the pipe groove. Then, the two rodless cylinders 15 are activated, and the two push rods 17 move closer to each other and insert into the pipe groove, eventually contacting the end of the corresponding pipe segment. At this point, the cut pipe segments are temporarily held together by the clamping force from both sides. Then, the output shafts of the second telescopic cylinders 14 are retracted, allowing multiple pipe segments to rise and eventually be removed from the pipe groove. Afterward, the operator drags the multiple pipe segments and activates the rodless cylinders 15 again to separate the push rods 17 from the pipe segments, making it easy to remove the multiple pipe segments.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
