[0025] The following describes the specific embodiments of the present utility model with reference to the drawings.
[0026] Embodiment 1
[0027] In this embodiment, a PE water supply pipe cutting device is proposed. Please refer to Figures 1-4 , the PE water supply pipe cutting device includes a first clamp 3 and a second clamp 4 for clamping the pipe, and a linear transmission structure.
[0028] The first clamp 3 is driven by the linear transmission structure to approach or move away from the second clamp 4. It also includes a cutting structure, and the cutting object of the cutting structure is the pipe clamped by the second clamp 4.
[0029] Please refer to Figure 1 , the above linear transmission structure is arranged on the workbench 1. Among them, the linear transmission structure includes a first seat 5 and a second seat 6. There is a lead screw 8 between the first seat 5 and the second seat 6, and two limit rods 9. The above first clamp 3 cooperates with the lead screw 8 and also slides with the two limit rods 9.
[0030] Please continue to refer to Figure 1 , the linear transmission structure is also equipped with a first motor 7 to drive the lead screw 8 to rotate. In this way, the first clamp 3 responsible for clamping one end of the pipe can approach or move away from the second clamp 4 by linear motion.
[0031] Please refer to Figure 1, the second clamp 4 is fixed on the workbench 1, and its lateral position is the above-mentioned cutting structure. In this embodiment, the cutting structure includes a support 2 adjacent to the second clamp 4. A tool 12 is movably carried above the support 2. The tool 12 is equipped with a cutter head 13. Of course, the tool 12 also has a second motor 14 for driving the cutter head 13 to perform a rotary cutting action.
[0032] Furthermore, the cutting structure further includes a lifter 10 installed above the workbench 1, and a transfer part 11 connected to the lifting part in the lifter 10. The transfer part 11 is connected to the tool 12, and the lifter 10 is connected to the transfer part 11. The lifter 10 drives the tool 12 to lift or lower.
[0033] Please refer to Figures 1-4 , in this embodiment, the second clamp 4 has an improvement. Specifically, the second clamp 4 is equipped with two blowing parts 15. The two blowing parts 15 are opposite and staggered on both sides of the pipe. When the second clamp 4 clamps the pipe, it encircles the pipe and blows air flow to the outer surface of the pipe. It should be noted that the blowing part 15 blows air to the pipe cutting place.
[0034] Please refer to Figure 2 , in this embodiment, the second clamp 4 includes a clamp seat 41. The clamp seat 41 is a U-shaped seat, and there is a movable block 42 inside it. The movable block 42 moves linearly in the clamp seat 41. The outer end side of the clamp seat 41 is equipped with a third motor 43. The driving part in the third motor 43 drives the movable block 42 to move in the clamp seat 41.
[0035] Furthermore, there is a first groove in the middle position of the movable block 42. On both sides of the first groove are first clamping blocks 44. There is a second groove in the middle position of the clamp seat 41. On both sides of the second groove are second clamping blocks 45. When the movable block 42 moves linearly in the clamp seat 41, the first clamping blocks 44 and the second clamping blocks 45 encircle the pipe.
[0036] In this embodiment, the main structural composition of the first clamp 3 is the same as that of the second clamp 4. The difference is that the second clamp 4 is equipped with blowing parts 15, and the first clamp 3 has a slider that cooperates with the lead screw 8 and the limit rod 9.
[0037] Furthermore, the second clamping block 45 is a mirror image of the first clamping block 44. The first clamping block 44 and the second clamping block 45 are divided into a first clamping part and a second clamping part. Specifically, the volume of the first clamping part is larger than that of the second clamping part. The first clamping part in the first clamping block 44 faces the second clamping part in the second clamping block 45, and the first clamping part in the second clamping block 45 faces the second clamping part in the first clamping block 44.
[0038] Please use Figure 2For reference, between the first groove and the second groove is the cutting area of the cutting structure. The above-mentioned lifter 10 drives the cutter 12 to lift or lower, so that the cutter head 13 enters or moves away from the cutting area to perform the cutting action.
[0039] In the embodiment, the first clamping part of the first clamping block 44 close to the cutting area and the first clamping part of the second clamping block 45 close to the cutting area are both equipped with a blowing part 15.
[0040] Please refer to Figure 3 and Figure 4 , the blowing part 15 includes a box 151 embedded in the first clamping parts of the first clamping block 44 and the second clamping block 45. The box 151 has a curved area adapted to the curvature of the pipe, and there are grooves 156 in this area. The box 151 is also equipped with a box cover 152, and the box cover 152 is fixedly combined with the box 151 through bolts 155. The box cover 152 has a number of air nozzles 153 and an air pipe installation nozzle 154. The air pipe installation nozzle 154 is used to connect the air pipe, and the air pipe introduces the air flow into the box 151 and blows it out from the air nozzles 153 to the straight cutting area.
[0041] In this embodiment, the blowing part 15 needs to be combined with an air pump (not shown in the figure). The functions of the blowing part 15 include cooling and blowing chips. Specifically, as described above, the cutting structure has a series of processes such as lowering the knife, cutting, and lifting the knife. In this embodiment, when the cutting structure lowers the knife, the blowing part 15 blows the cutting area of the pipe. After cutting, that is, during the lifting of the cutting structure, it still blows the cutting position. The blowing is continuous throughout the cutting process. The advantage of doing this is that on the one hand, it can pre-clean the residues in the previous cutting process, on the other hand, it can blow chips and cool the cutting area during the current cutting (it also has a cooling effect on the cutter head 13). Finally, after cutting, it can blow chips and cool the entire cutting area more comprehensively to improve the use effect.
[0042] In this embodiment, the box 151 has grooves 156. When the box 151 is close to the pipe, the temperature at the cutting part of the pipe is transmitted to the inside of the box 151 through the grooves 156 by the flowing air inside the box 151, and then dissipated outward through the air flow, further improving the cooling effect of the cutting part.
[0043] In this embodiment, the working process of the PE water supply pipe cutting device is as follows:
[0044] First, the first clamp 3 and the second clamp 4 reserve enough space for the pipe to pass through. When the pipe enters the first clamp 3 and the second clamp 4, the first clamp 3 and the second clamp 4 lock it.
[0045] Second, the cutting structure cuts the pipe located at the second clamp 4. After cutting, the second clamp 4 is released. The first clamp 3 is driven by the linear drive structure to push the pipe to move relative to the second clamp 4, re-determine the cutting position, and repeat the above cutting process.
[0046] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "below" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.
