[0032] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] The utility model provides a circumferential circle equal - division cutting device, which includes a fixed table 1, a plurality of cutting parts 2 and a rotating part 3. The fixed table 1 is provided with a limiting and accommodating part 4. A raw material 6 can be placed in the limiting and accommodating part 4, and the limiting and accommodating part 4 can axially limit the raw material 6. The fixed table 1 is provided with a plurality of sliding grooves 5, and all the sliding grooves 5 are annularly arranged and distributed along the central axis of the limiting and accommodating part 4. The length direction of the sliding groove 5 is consistent with the radial direction of the limiting and accommodating part 4; the cutting part 2 is arranged in the sliding groove 5 and is in sliding fit with the sliding groove 5. The cutting part 2 includes a guiding part 21 and a cutting part 22, and the cutting part 22 can cut the wall surface of the raw material 6; the rotating part 3 is rotatably connected to the fixed table 1, and a plurality of guiding grooves 31 are arranged on the rotating part 3. The guiding part 21 is located in the guiding groove 31 and is in sliding fit with the guiding groove 31.

[0034] The basic usage method of the utility model:

[0035] S1: Workers place the raw material 6 (pipe fitting blank) at the limiting and accommodating part 4, and the limiting and accommodating part 4 temporarily centers the raw material 6.

[0036] S2: Rotate the rotating part 3 so that the guiding part 21 slides in the guiding groove 31, and then the cutting part 2 slides in the sliding groove 5. Finally, the cutting part 22 approaches the raw material 6 to cut the wall surface of the raw material 6 (when all the cutting parts 22 contact the raw material 6, the cutting part 22 contacts the outer wall of the raw material 6 and combines with the function of the limiting and accommodating part 4, and the raw material 6 is limited).

[0037] S3: Rotate the rotating part 3 in the reverse direction so that the cutting part 22 moves away from the raw material 6, and the worker takes down the product.

[0038] The raw material 6 of the utility model is tubular. Multiple equally - divided incisions 61 need to be opened at the top of the raw material 6 located on the limiting and accommodating part 4, and each incision 61 is cut by the corresponding cutting part 22.

[0039] Specifically, a plurality of convex blocks 7 are arranged on the fixed table 1, and all the convex blocks 7 are circumferentially arranged around a center. Two adjacent convex blocks 7 form a sliding groove 5.

[0040] The limiting and accommodating part 4 includes a receiving groove 41 and a sleeve column 42. An equal - value gap is provided on the outer peripheral surfaces of the receiving groove 41 and the sleeve column 42. The raw material 6 can be sleeved outside the sleeve column 42, and the raw material 6 can be accommodated in the gap. The interaction between the sleeve column 42 and the cutting part 2 enables the raw material 6 to be limited.

[0041] The guiding groove 31 is located outside the outer end of the sliding groove 5. The guiding groove 31 is arc-shaped, and one end of the guiding groove 31 is not equidistant from the center of the limiting accommodating part 4. When all the guiding parts 21 slide from one end of the guiding groove 31 to the other end, the cutting part 2 will gradually slide from the outside of the sliding groove 5 to the inside, or from the inside to the outside. When the cutting part 2 is in the first position, the cutting part 22 is far away from the raw material 6. At this time, it is convenient to put the raw material 6 into the limiting accommodating part 4 or take out the finished product from the limiting accommodating part 4. When in the second position, the cutting part 22 can perform the cutting work to cut the raw material 6.

[0042] In order to facilitate the concentric rotational connection between the rotating part 3 and the fixed table 1, a rotating groove 11 is provided on the upper surface of the fixed table 1. The rotating part 3 is directly arranged in the rotating groove 11, so that the rotating part 3 can rotate in the rotating groove 11, and the rotating part 3 is flush with the top surface of the fixed table 1, improving the aesthetics and reducing the overall occupied space of the device.

[0043] The present utility model further includes a transmission member 8. The fixed table 1 is provided with a through hole. The transmission member 8 includes a connecting column 81 and a connecting handle 82. The bottom of the connecting column 81 is fixed to the rear half of the connecting handle 82. The top of the connecting column 81 passes through the through hole and is fixed to the rotating part 3. The front end of the connecting handle 82 is hinged to the actuator of the driving component 9. The transmission member 8 is used to transmit the power of the driving component 9 to the rotating part 3, playing an intermediate bridging role. When the driving component 9 is started, its actuator causes the connecting handle 82 to swing back and forth, realizing the reciprocating rotation of the rotating part 3.

[0044] The driving component 9 in the present utility model can be a cylinder or an oil cylinder. The free end of the telescopic rod of the cylinder or the oil cylinder is hinged to the front end of the handle. When the telescopic rod of the cylinder or the oil cylinder expands and contracts, the connecting handle 82 can be caused to swing back and forth, realizing the reciprocating rotation of the rotating part 3.

[0045] The present utility model further includes a housing 10. The cutting part 2, the fixed table 1, the rotating part 3, the transmission member 8 and the driving component 9 are all located inside the housing 10. The bottom of the housing 10 is fixed to the workbench.

[0046] The setting of the housing 10 can prevent the above-mentioned components from being contaminated by dust, water vapor, corrosive gases and foreign objects, ensuring the long-term stable operation of the device. In addition, since the cutting part 22 of the present utility model is covered by the housing 10, it provides protection for the safety of workers, can prevent the hands of workers from being cut by the cutting part 22, improves the safety of production and avoids potential safety hazards.

[0047] The utility model further includes a mounting base 20. A channel 12 is provided at the center of the fixed table 1. The diameter of the channel 12 is smaller than that of the receiving groove 42. The top of the mounting base 20 is fixed at the center of the bottom surface of the fixed table 1. The mounting base 20 is provided with a through cavity 201. A lifting device 30 is fixed at the bottom of the mounting base 20. The actuator of the lifting device 30 can sequentially pass through the through cavity 201 and the channel 12 and be fixed to the sleeve column 42. Since the gap between the receiving groove 41 and the sleeve column 42 is only enough to accommodate the raw material 6 or the product, in this case, it is not convenient to take out the product after it is manufactured. At this time, the actuator of the lifting device 30 shortens, retracts the sleeve column 42 inward, and the sleeve column 42 moves below the receiving groove 41, while the product remains in the receiving groove 41, so that the staff can pick out the product from the receiving groove 41 with tweezers. After the product is removed, the actuator of the lifting device 30 elongates, and the sleeve column 42 rises to reset, so as to be used for centering the raw material 6 next time. The lifting device 30 of the utility model is a cylinder, and its actuator is a telescopic rod.

[0048] The inner wall shape of the channel 12 is polygonal, and the shape of the lower half of the sleeve column 42 is also polygonal. The shapes of the channel 12 and the sleeve column 42 fit each other. When the sleeve column 42 is lifted or lowered, the channel 12 provides linear guidance for the lifting and lowering of the sleeve column 42.

[0049] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the inventive creation of the utility model.
