[0035] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0036] This utility model provides an automatic rotary type 3 punching and cutting machine, as shown in the attached figure. Figures 1 to 4 As shown, the punching machine includes a base 1, a connecting frame 2, a turntable 3, a clamping component 4, and an elastic component 5, as well as a drive motor 6 and a drive cylinder 7. The base 1 is equipped with an upper frame 11 and a worktable 12. The connecting frame 2 is embedded in and fixed to the worktable 12, and a circular opening is formed above the connecting frame 2. The upper frame 11 is located on one side of the worktable 12, and a liftable punching body 8 is disposed within the upper frame 11. The punching body 8 fixes an upper die 91, allowing the upper die 91 to rise and fall relative to one side of the turntable 3.

[0037] As attached Figure 3 and 5 As shown, a housing 13 is located below the fixed connecting frame 2 on the base 1. The lifting cylinder 7 and the drive motor 6 are both fixed inside the housing 13, and a lifting seat 71 is also installed inside the housing 13. The lifting cylinder 7 can be a pneumatic cylinder, hydraulic cylinder, or electric push rod, etc., a drive element with a piston rod. The piston rod of the lifting cylinder is fixed to the lifting seat 71, and a bearing seat 72 is fixed on the lifting seat 71. The turntable 3 is connected to the bearing seat 72 via a spline 31 fixed at its bottom. Specifically, the spline 31 passes through the connecting frame 2 into the housing 13 and then connects to the bearing seat 72, so that the spline 31 and the turntable 3 are axially fixed relative to the bearing seat 72 and can only rotate. The extension and retraction of the piston rod of the drive cylinder 7 drives the lifting seat 71 and the spline 31 to rise and fall relative to the housing 13 and the connecting frame 2, thus allowing the turntable 3 to rotate and rise and fall only along its axial direction relative to the connecting frame 2. Preferably, guide columns 14 are fixed on both sides inside the housing 13, and linear bearings 73 are fixed on both sides of the lifting seat 71. The two linear bearings 73 are respectively fitted on the outside of the two guide columns 14, thereby restricting the lifting seat 71 to only be raised and lowered vertically and not rotated.

[0038] Please refer to the appendix. Figure 4 and 8As shown, the bottom of the spline 31 is fixed with a limiting shaft 32, the bottom of the limiting shaft 32 is provided with a diameter expansion part 321 with enlarged diameter, the limiting shaft 32 is adapted to pass through the inner ring of the bearing seat 72, and the diameter expansion part 321 is located at the bottom of the inner ring of the bearing seat 72. When the piston rod of the lifting cylinder 7 drives the lifting seat 71 to descend, the spline 31 and the rotating disc 3 are driven to descend by pulling down the diameter expansion part 321, and the structure of the diameter expansion part 321 strengthens the pressure bearing strength of the spline 31 under the pressure, so that the spline 31 and the rotating disc 3 can be stably pressed and descended. Further, the diameter expansion part 321 is provided on a limiting shaft 32, the side surface of the limiting shaft 32 is screw-connected with a second bolt 33, the bottom surface of the spline 31 is inwardly recessed to form a mounting hole 301, and the side surface of the spline 31 is provided with a counterbore hole 302 penetrating into the mounting hole 301. During installation, the limiting shaft 32 is first passed through the bearing seat 72, then the limiting shaft 32 is inserted into the mounting hole 301, and then the second bolt 33 is screw-connected to the fastening after passing through the counterbore hole 302 and the limiting shaft 32, so that the bearing seat 72 can be arranged between the spline 31 and the diameter expansion part 321.

[0039] The output shaft of the driving motor 6 is fixed with a gear 61, the gear 61 is engaged with the spline 31, and further, the utility model can be provided with a control system which can be a PLC controller for controlling the working state of the driving motor 6 and the lifting cylinder 7, the signal control of the control system can realize that the driving motor 6 drives the rotating disc 3 to pause after rotating 180° each time, and the structure of the gear 61 engaged with the spline 31 is not affected by the lifting of the rotating disc 3, so that the spline 31 and the gear 61 always maintain the engaged state. Through the rotating of the rotating disc 3 by 180° each time, the lower dies 92 on both sides of the rotating disc 3 can be sequentially rotated to be below the upper die 91, so that the lower die 92 outside the workbench 12 can be taken out and placed in the process of the formed fabric and the placed fabric to be punched, the lower die 92 below the upper frame 11 is pressed by the upper die 91 to form the punching process of the fabric, then the rotating disc 3 is rotated by 180°, so that the lower die 92 completing the punching of the fabric is rotated to the outside of the workbench 12, and the lower die 92 placing the fabric to be punched is rotated to the inside of the upper frame 11. Such a cycle realizes the taking out of the formed fabric and the placing of the new fabric in the punching process, forms a continuous automatic production process, and significantly improves the fabric punching processing efficiency.

[0040] As shown in the accompanying drawings, Figure 9 As shown, the rotating disc 3 is pivotally connected with the pressing members 4 on both sides of the position for placing the lower die 92, and further referring to the accompanying drawings, Figures 5 to 7The two ends of the pressing member 4 are respectively a pressing plate 41 and a guide plate 42, and the part of the pressing member 4 between the pressing plate 41 and the guide plate 42 is pivotally connected with the bottom surface of the rotating disc 3, and the pivotally connected structure can be that a rotating shaft 34 is fixedly connected with the bottom of the rotating disc 3, the rotating shaft 34 passes through the part of the pressing member 4 between the pressing plate 41 and the guide plate 42, the axis of the rotating shaft 34 forms the pivotally connected axis of the pressing member 4 and the rotating disc 3, so that the pressing member 4 rotates around the rotating shaft 34. In addition, since the two sides of the rotating disc 3 relative to the rotating axis are both the positions where the lower moulds 92 are placed, the rotating shaft 34 can pass through the pressing member 4 on the same side of the rotating disc 3 where the two lower moulds 92 are placed.

[0041] Referring to the drawings again, Figure 10 And 11 The elastic member 5 is connected with the pressing member 4, and the elastic force formed by the elastic member 5 pulls the pressing member 4 to swing, so that the pressing plate 41 presses the lower mould 92 downwards, and the guide plate 42 swings to be inclined downwards and to the middle of the rotating disc 3. Specifically, the elastic member 5 can be a tension spring with hooks at both ends, a pull ring 43 is arranged above the rotating shaft 34 on the side of the pressing member 4 facing the rotating disc 3, the hooks at both ends of the tension spring are respectively hooked on the pull ring 43 of the corresponding pressing member 4, and the elastic force of the tension spring is used to pull the two pressing members 4 to the middle of the rotating disc 3, so that the pressing plate 41 above the two pressing members 4 swings to the middle of the rotating disc 3 and downwards, to form the pressing force for pressing the lower mould 92, thereby forming the elastic self-locking mechanism for the lower mould 92.

[0042] After the above structure is adopted, when the lower mould 92 needs to be replaced, the lifting cylinder is controlled to drive the lifting seat 71 to descend, so that the rotating disc 3 synchronously moves downwards relative to the connecting frame 2, the guide plate 42 is blocked by the bottom surface of the connecting frame 2 and swings to the middle of the connecting frame 2, the pressing plate 41 is lifted to be separated from the top surface of the lower mould 92, and the lower mould 92 can be easily taken out at this time. Preferably, a rotatable guide wheel 44 is arranged at the bottom of the guide plate 42, so as to reduce the frictional force of the guide plate 42 during the swinging process to the middle of the connecting frame 2. After the new lower mould 92 is placed again, the lifting cylinder is controlled to drive the lifting seat 71 to ascend, so that the rotating disc 3 synchronously moves upwards relative to the connecting frame 2, the guide plate 42 is no longer limited by the bottom surface of the connecting frame 2, and at the same time, under the elastic force of the elastic member 5, the pressing plate 41 above the two pressing members 4 automatically swings to the middle of the rotating disc 3 and downwards to press the lower mould 92, thereby forming the mechanism of the upward linkage for pressing the lower mould 92. It can be seen that the lower mould 92 can be conveniently and labor-savingly replaced.

[0043] In addition, the bottom of the rotating disc 3 is fixedly connected with a connecting piece 35, the connecting piece 35 has a vertical strip-shaped hole, the end surface of one end of the rotating shaft 34 is screw-connected with a first bolt 36, the first bolt 36 passes through the strip-shaped hole and the rotating shaft 34 and is connected to fastening. In the structure, the distance between the pressing plate 41 and the rotating disc 3 can be adjusted by adjusting the height of the rotating shaft 34, so that the lower die 92 with different thicknesses can be pressed.

[0044] In summary, when the rotating disc 3 is driven to descend by the lifting cylinder, the guide plate 42 of the pressing piece 4 is blocked from swinging by the connecting frame 2, and the pressing plate 41 is automatically lifted to release the locking of the lower die 92. After the lower die 92 is replaced, the rotating disc 3 is lifted, and the elastic force formed by the elastic piece 5 makes the pressing plate 41 press down to fix the new lower die 92, so that the efficient operation of automatically locking and unlocking the lower die 92 is realized while the rotating disc 3 is switched by lifting, without manually disassembling the fastener for locking the lower die, and the replacement process of the lower die 92 is simplified. At the same time, the intermittent rotation of the rotating disc 3 at 180° separates the blanking station from the die changing station, workers can replace the die on the outside safely, and the stamping operation is carried out synchronously on the inside, so that the production continuity and the operation convenience are taken into account; the bearing structure of the spline 31 limit shaft 32 expansion part 321 and the guide column 14 guarantees the stability and the pressure strength in the lifting process, avoids the jamming, and is especially suitable for the flexible production line which needs to frequently change the die.

[0045] The above is only the specific implementation manner of the present application, but the design concept of the present application is not limited to this, and any non-essential change of the present application by using the concept should belong to the behavior of infringing the protection range of the present application.
