[0029] A mounting groove 11 is provided at the top of the base 1, and a driving roller group 12 and a discharging roller 13 are installed in the mounting groove 11. A plurality of discharging rollers 13 are provided, and are located at the discharging end of the driving roller group 12 in contact with each other, and at least one active roller is provided among the plurality of discharging rollers 13. When one end of the lower pressing plate 6 contacts the discharging roller 13, the guide hole 51 is located directly below the punching mechanism 7.

[0030] The driving roller group 12 includes a cross-arranged lifting mechanism and a one-way roller 121, and when the upper pressing plate 5 presses the lower pressing plate 6, the lifting mechanism moves downward, and the one-way roller 121 contacts the lower pressing plate 6 and can rotate.

[0031] Specifically, the lower pressing plate 6 can be used in a disposable manner or in a reusable manner; and for workpieces of different shapes, corresponding slots of different shapes can be opened on the lower pressing plate 6 to achieve the snap-fitting and matching between the workpiece and the lower pressing plate 6.

[0032] Furthermore, the lifting mechanism includes a lifting rod 122 embedded in the mounting groove 11, and a supporting roller 123, a limiting roller 124 and a spring 125 are sequentially installed on the lifting rod 122 from top to bottom, and the supporting roller 123 and the limiting roller 124 are non-rotatable.

[0033] Among them, the specific installation method of the spring 125 is: one end is fixed on the lifting rod 122, and the other end is fixed in the installation groove 11, so as to effectively realize the compression of the spring 125 when the lifting rod 122 descends, thereby ensuring that the lifting rod 122 can have the effect of automatic rebound and reset.

[0034] In addition, regarding the limiting roller 124, a structure with greater surface friction or a gear structure can be provided to limit the one-way roller 121 from rotating when the lifting mechanism is raised, and the rotation direction of the one-way roller 121 is to transmit the lower pressure plate 6 in the direction where the discharge roller 13 is located.

[0035] Furthermore, a discharge hole is provided on the lower pressure plate 6, a blanking gap is provided between the driving roller set 12 and the discharge roller 13, and a blanking hole 14 is provided on the base 1 below the blanking gap.

Based on the above structure, the driving principle of the moving device 3 is as follows: start the driving motor 31 to drive the driving screw 32 in the guide rail 33 to rotate through the driving motor 31, and the driving screw 32 forms a spiral drive with the slide 34 during the rotation process to convert the rotation drive into a moving drive, thereby effectively driving the slide 34 to move and achieve the effect of moving drive. The guide rod 35 is used to effectively prevent the slide 34 from rotating with the driving screw 32 and provide a guiding effect for the movement of the slide 34.

[0037] It is worth noting that the frame 2 includes an L-shaped side frame 21 and a top frame 22. There are at least six L-shaped side frames 21, and two of the L-shaped side frames 21 correspond to the two ends of the top frame 22, and the two moving devices 3 are respectively fixed between the two ends of the top frame 22 and the corresponding L-shaped side frames 21; and the four L-shaped side frames 21 correspond to the two ends of the two moving devices 3. Based on this, on the one hand, the main support structure of the integrated machine is relatively simple, and on the other hand, the stability of the main support structure in the integrated machine is ensured.

[0038] Preferably, a reinforcing support plate 23 is welded between each L-shaped side frame 21 and the moving device 3 , and the reinforcing support plate 23 is fixed at the corner of the L-shaped side frame 21 .

[0039] Preferably, the punching mechanism 7 includes a driving device and a drill bit, and a mounting plate 8 is fixedly mounted on the driving device, a guide column 9 is fixed on the top of the mounting plate 8, and the guide column 9 passes through the top of the frame 2.

[0040] Based on this, the stability of the drill bit during the lifting and drilling process can be effectively improved, and the drilling deviation caused by the shaking of the drill bit can be reduced.

[0041] The working principle and use process of the present invention. When using the all-in-one machine provided by the present invention:

[0042] First, take the workpiece to be punched and the lower pressing plate 6 adapted to the workpiece, and place the lower pressing plate 6 in a Figure 5 The method shown is placed on the driving roller group 12 of the base 1, the workpiece to be punched is placed on the lower pressing plate 6, the moving device 3 is started to adjust the position of the upper pressing plate 5 so that the upper pressing plate 5 is positioned directly above the lower pressing plate 6, and then the lifting cylinder 4 is started to drive the upper pressing plate 5 to press down, thereby cooperating with the lower pressing plate 6 to clamp the workpiece. In this process, the limit block 61 is gradually inserted into the limit groove 52 to achieve the positioning connection between the upper pressing plate 5 and the lower pressing plate 6. At the same time, the lower pressing plate 6 is subjected to downward pressure to press the lifting rod 122 downward, so that the lifting rod 122 retracts into the installation groove 11. In this state, the spring 125 is squeezed to form a contracted state, and the supporting roller 123 and the limiting roller 124 also descend accordingly. In this state, the limiting roller 124 is separated from the one-way roller 121, so that the one-way roller 121 can effectively rotate in one direction;

[0043] Then, the moving device 3 is started to drive the upper pressing plate 5, the workpiece (not punched) and the lower pressing plate 6 in the clamped state to move toward the punching mechanism 7 until one end of the lower pressing plate 6 just contacts the discharge roller 13, and the guide hole 51 on the upper pressing plate 5 is just positioned directly below the punching mechanism 7, thereby ensuring that the punching mechanism 7 can form a precise positioning punching, and when the lower pressing plate 6 contacts the discharge roller 13, since the discharge roller 13 is not driven, the discharge roller 13 cannot rotate, thereby enabling the lower pressing plate 6 to be effectively positioned at this position, ensuring the accuracy of the punching positioning;

[0044] Next, after the punching mechanism 7 completes the punching, the active roller in the discharge roller 13 is started so that the multiple discharge rollers 13 all rotate, and the moving device 3 is started at the same time to send the upper pressure plate 5, the workpiece (completed punching) and the lower pressure plate 6 to the discharge roller 13. The feeding distance can be preset so that the bottom of the lower pressure plate 6 can contact the discharge roller 13. After the feeding is completed, the lifting cylinder 4 is quickly retracted to separate the upper pressure plate 5 from the lower pressure plate 6. The lower pressure plate 6 carries the workpiece with completed punching under the drive of the discharge roller 13 for discharging or unloading, and the upper pressure plate 5 is reset to perform the next clamping and conveying of the workpiece.

[0045] When the lower pressing plate 6 is being conveyed to the material roller 13, if the workpiece is punched as a through hole, when the discharge hole on the lower pressing plate 6 corresponds to the blanking gap, the workpiece waste residue generated by the punching can fall into the blanking hole 14 through the blanking gap and complete the discharge of the waste residue.
